The said truck body 2 is provided with a plurality of protective belts 2-3 with adjustable lengths. Both ends of -3 are movably connected to both sides of the truck body 2 in the width direction, respectively. The supporting plate 5 is hinged with the lower end of the truck body 2, and a limiting device is arranged between the supporting plate 5 and the truck body 2. When the supporting plate 5 rotates, the length of the supporting plate 5 and the truck body 2 The included angle of the direction is not more than 90 degrees, the push device includes a push rod 6 and a push plate 7, the push rod 6 is slidably arranged on the upper part of the truck body 2, and the sliding direction of the push rod 6 is perpendicular to The plane where the length direction and width direction of the truck body 2 are located, the cross section of the push plate 7 is arc-shaped, and the concave side of the arc-shaped push plate 7 faces the position where the pallet 5 of the truck body 2 is provided. On one side, the end of the push rod 6 adjacent to the support plate 5 is hinged on the convex side of the push plate 7, and the connecting device includes a rack 9, two gears 8 that mesh with each other, a first connecting rod 10 and a first connecting rod Two connecting rods 11 , the middle part of the first connecting rod 10 is hinged on the truck body 2 , the rack 9 is slidably arranged on the truck body 2 , and the sliding direction of the rack 9 is the same as that of the push rod 6 The sliding direction is the same and the rack 9 is located on the lower side of the push rod 6. As shown in FIG. 4, a slider 9-1 is slidably arranged on the lower side of the rack 9, and the sliding direction of the slider 9-1 is perpendicular to the teeth In the length direction of the bar 9, the upper end of the first connecting rod 10 is hinged with the slider 9-1. As shown in FIG. 8, one end of the second connecting rod 11 is hinged with the lower end of the first connecting rod 10. The other end of the second connecting rod 11 is hinged on the support plate 5 , the lower side of the push rod 6 is provided with a toothed belt, and the two gears 8 are both rotatably connected to the truck body 2 . A gear 8 is meshed with the toothed belt of the push rod 6, and the other gear 8 is meshed with the rack 9. As shown in FIG. 7, when the plane where the pallet 5 is located is perpendicular to the length direction of the truck body 2 , the arc-shaped push plate 7 is completely fitted with the arc-shaped wall plate 2-2; when the support plate 5 rotates in the direction close to the truck body 2, the push rod 6 pushes the push plate 7 away from The direction of the truck body 2 moves.

The upper part of the truck body 2 according to the present invention is provided with a support frame 3, the support frame 3 and the roller 4 are located on the same side of the truck body 2, and the bottom of the support frame 3 is provided with a support wheel 3-1. 3 is provided with limit holes 3-2 arranged along the length direction of the support frame 3, the described truck body 2 is provided with a limit hook 3-3, and the limit hook 3-3 is hung on one of the support frames 3 inside the limit hole 3-2. By hanging the limit hooks 3-3 in different limit holes 3-2, when the support wheel 3-1 is supported on the ground, the angle between the length direction of the truck body 2 and the ground is adjusted, so as to facilitate the handling of different length of oxygen cylinder.

The top of the truck body 2 of the present invention is provided with a handle 1, the handle 1 is a U-shaped frame, and the two ends of the U-shaped frame are respectively connected to the fixing frame 2-1. The frame extends to the convex side of the wall plate 2 - 2 , and the plane where the U-shaped frame is located is perpendicular to the length direction of the truck body 2 . The handle 1 of the U-shaped frame is convenient not only to push the oxygen cylinder truck, but also to lift the truck body 2 into a vertical state.

Working principle: As shown in Fig. 3, Fig. 5 and Fig. 6, the present invention is mainly to facilitate the handling of flat-bottomed oxygen cylinders. When the oxygen cylinder 12 needs to be loaded, the oxygen cylinder truck is first pushed to the vicinity of the oxygen cylinder 12 to make the truck body. The concave side of the wall plate 2-2 of the The distance between the oxygen cylinders 12 can be just contacted. For the convenience of safety, adjust the protective belt 2-3 to an appropriate length and put it on the oxygen cylinder 12, and go around the pallet 5 and the truck body in the direction toward the oxygen cylinder 12. The hinge shaft of 2 rotates the truck body 2, and after the pallet 5 touches the ground, it continues to push, so that the angle between the plane where the pallet 5 is located and the length direction of the truck body 2 gradually decreases, the second connecting rod 11 is under pressure, and the second connecting rod 11 is under pressure. The second connecting rod 11 pushes the hinged end of the first connecting rod 10 to rotate in the direction away from the oxygen cylinder 12 , the upper end of the first connecting rod 10 rotates in the direction close to the oxygen cylinder 12 , and the upper end of the first connecting rod 10 passes through the slider 9 -1 drives the rack 9 to slide in the direction close to the oxygen cylinder 12, the rack 9 drives the two intermeshing gears 8 to rotate, the gear 8 drives the push rod 6 to slide toward the oxygen cylinder 12 through the toothed belt, and the push rod 6 pushes the The push plate 7 moves towards the direction close to the oxygen cylinder 12. After the push plate 7 touches the oxygen cylinder 12, it will push the oxygen cylinder 12 to tilt away from the oxygen cylinder truck, so that the bottom surface of the oxygen cylinder 12 and the ground are formed. When there is a gap, push the oxygen cylinder truck with your feet to move towards the direction close to the oxygen cylinder 12, so that the pallet 5 is inserted into the gap between the bottom surface of the oxygen cylinder 12 and the ground, when the oxygen cylinder truck is pushed forward, the oxygen When the inclination angle of the bottle 12 increases, it is possible to overturn. In order to avoid the overturning, the angle between the pallet 5 and the length direction of the truck body 2 can be increased when the oxygen cylinder truck is propelled, and the protective belts 2-3 can be used. Avoid tipping over of the oxygen cylinder 12 . When the pallet 5 is extended into more than 2/3 of the diameter of the bottle body of the oxygen cylinder 12, turn the truck body 2 away from the oxygen cylinder 12, and the plane where the pallet 5 is located and the length of the truck body 2 clamp The angle increases, the second connecting rod 11 pulls the first connecting rod 10 to reverse, the upper end of the first connecting rod 10 drives the rack 9 to move away from the oxygen cylinder 12, and the rack 9 drives the push rod 6 through the gear 8 to drive The push plate 7 moves away from the oxygen cylinder 12, and the oxygen cylinder 12 falls down due to its own weight. When the inclination angle of the oxygen cylinder 12 is too large, when the truck body 2 rotates backwards, it can also be pulled back through the protective belt 2-3. The oxygen cylinder 12 falls, and the bottom surface of the oxygen cylinder 12 falls on the pallet 5. When the included angle between the plane where the pallet 5 is located and the length direction of the truck body 2 is a right angle, the included angle cannot continue to increase due to the limiting device. , continue to pull the truck body 2 away from the oxygen cylinder 12, so that the truck body 2 rotates around the axis of the roller 4, the support plate 5 lifts the oxygen cylinder 12, and after the rotation to the support wheel 3-1 is on the ground, the oxygen cylinder 12 It completely falls into the concave side of the truck body 2, and the oxygen cylinder can be transferred by pushing the oxygen cylinder truck.

When pushing the oxygen cylinder to incline, the arc-shaped pushing plate 8 can prevent the cylindrical oxygen cylinder 12 from skewing to both sides. When the truck body 2 is rotated to reduce or increase the angle between the length direction and the plane where the pallet 5 is located, the truck body 2 itself becomes a lever, which saves more effort when pushing the oxygen cylinder.

The oxygen cylinder transport vehicle of the present invention is not limited to the transport of oxygen cylinders, and is suitable for various long and slender cylinder bodies and tanks, and any products using this structure and function are within the protection scope of the present invention.
