Detailed Description
The features and advantages of the present invention will become more apparent and appreciated from the following detailed description of the invention.
The invention provides an adjustable horizontal support vehicle, which comprises two bottom cross beams, four rotary screw rods 1, four hand wheels 2, four support sleeves 3, two channel steel cross beams 4, two rectangular pipe cross beams 5 and four thrust ball bearings 6 as shown in figures 1 and 2, wherein,
the two bottom cross beams form a bottom frame through bottom longitudinal beams or reinforcing ribs, two support sleeves 3 are respectively fixed at the upper parts of the bottom cross beams, the support sleeves 3 are of a cylinder structure with openings at two ends, thrust ball bearings 6 are fixed inside the support sleeves, and a hand wheel 2 is fixed at the opening end and used for limiting the hand wheel 2 to move up and down; the middle of the hand wheel 2 is of a threaded hole structure, the lower end of the rotary lead screw 1 sequentially penetrates through the hand wheel 2, the thrust ball bearing 6, the support sleeve 3 and the bottom cross beam to form a free end, and the upper end of the rotary lead screw is fixed on the channel steel cross beam 4 to form a fixed end; the hand wheel 2 is in threaded fit with the rotary lead screw 1, and the rotary lead screw 1 is extended or shortened between the bottom frame and the channel steel beam 4 by rotating the hand wheel 2 to drive the channel steel beam 4 and the upper structure thereof to move up and down;
two through hole structures I corresponding to the positions of the rotary lead screws 1 are processed on two side plates of the channel steel beam 4, through holes are formed in the upper ends of the rotary lead screws 1, the channel steel beam 4 is connected with the rotary lead screws 1 through threaded connecting pieces I7, and the threaded connecting pieces I7 on the side plates of the channel steel beam 4 form a longitudinal hinge structure at the positions;
