Description
Technical Field
The invention relates to a radial stacker and a supporting device thereof.
Background
The radial stacker is common equipment for distributing and stacking bulk materials such as copper ores, aluminum ores, coal mines and the like, and generally comprises a truss, a telescopic belt conveyor, a tail traveling part, a head traveling part, a supporting device, a steering cylinder of the head traveling part, a hydraulic station, an electric cabinet, a cab, a pedestrian pavement platform and the like. When the radial stacker walks in a straight line, the head walking part and the tail walking part are placed in parallel; when the radial stacker makes fan-shaped movement, the head walking part and the tail walking part are vertically or nearly vertically placed, the tail walking part is kept motionless, and the head walking part rotates around the rotary bearing at the upper end of the tail walking part to finish fan-shaped cloth. When the radial stacker is switched between front-back linear walking and fan-shaped stacking, the head walking part is supported by the head supporting device to be suspended, then the head walking part is rotated by about 90 degrees by the steering oil cylinder, and the head supporting device is contracted back again to finish steering of the head walking part. The two supporting devices are generally arranged, and are symmetrically arranged on the frame of the head walking part, and as the hydraulic stations, the electric control boxes and other parts are hung on the two sides of the truss, the gravity center of the equipment often has a certain offset distance to the hanging side of the hydraulic stations. Meanwhile, the grounding points of the two supporting devices can be different at any time, and the working conditions are very complicated.
The supporting device of the existing radial stacker is characterized in that a connecting flange is welded outside a cylinder barrel of a supporting oil cylinder and is arranged on a rack at the head of the radial stacker through bolts. One end of the piston rod is a piston and is arranged in the cylinder barrel; the other end of the piston rod is connected with the chassis through a cross axle structure. The supporting oil cylinder directly supports the equipment, and the oil cylinder is connected with the chassis through a cross shaft structure. When the device is used, the head of the device is only supported in the head-tail direction of the device, and the ground working condition is uneven and changeable, the supporting oil cylinder is not perpendicular to the ground, and the included angle between the supporting oil cylinder and the ground is continuously changed, so that the oil cylinder receives extremely large radial force in the head-tail direction of the device. On the other hand, the hydraulic station, the electric cabinet and other parts are hung on two sides of the truss, and the gravity center of the equipment often has a certain offset distance to one side of the hydraulic station, so that the load size difference of the two support cylinders is large in the supporting process, and the equipment has a certain inclination in the supporting process, so that the support cylinders are stressed unevenly in the left-right direction and are 'choked'.
Therefore, it is desirable to provide a new technique to solve the problem that the support cylinder of the existing radial stacker is often damaged.

And the bottom plate 612, wherein the bottom plate 612 is formed by drilling positioning holes of bottom leg nails after steel plate blanking, and then removing assembly welding. The bottom leg nails 613 are made of medium carbon steel, are formed by blanking round steel, performing thermal refining, then removing assembly welding, and surfacing the surface of the round steel with HF800 for 5mm thickness after the assembly welding is finished, so that the wear resistance is improved. The lifting lug 614 is formed by blanking a steel plate and then removing assembly welding. The ball gland 62 is manufactured by blanking a steel plate, processing the spherical surface of the press-joint ball and the threaded hole of the connecting bolt, and dividing the ball gland into two halves after the processing is completed, wherein the two halves are combined for use.
Wherein, the pin shaft 4 is processed with an excircle matching surface, a baffle ring groove and the like. A baffle 7 is arranged in the baffle circular groove to prevent the pin shaft 4 from moving, and the baffle is fixed on the lug plate by bolts 8.
The oil supply loop of the supporting oil cylinders of the radial stacker is controlled by a control valve, and one path of hydraulic oil simultaneously provides hydraulic oil for the two supporting oil cylinders which are arranged in a bilateral symmetry manner through two tee joints. For complex working conditions, uneven ground and gravity center deflection to one side of the suspension of the hydraulic station, the supporting oil cylinder can also control the head of the radial stacker to lift by one key (manually or automatically), so that the effect of self-adaptive adjustment is achieved.
Two control modes of the supporting device and signals for supporting the supporting device are as follows: if the supporting action is manual control, the telescopic travel of the inner cylinder of the supporting device is consistent with the telescopic travel of the oil cylinder, and is determined by the mechanical limiting structure of the oil cylinder, the supporting device can reach the limit travel without action, and the completion of supporting is indicated. If the control is automatic, the control can be performed by using the pressure of the hydraulic system as a signal, and the detection of the system pressure reaches the system pressure, namely the limit stroke is reached at the moment, which indicates that the supporting process is completed.
