The baffle plate can effectively prevent the support pin 475 from falling out of the pin hole, thereby ensuring the normal operation of the work platform 400.

The working principle and process of the trolley crusher working platform 400 on the broken trolley is as follows: under normal circumstances, the cylinder is in a contracted state, and the base 470 has a certain distance from the ground to facilitate transportation. The 470 and the base 460 are mutually abutted, and the plurality of fixed legs 462 are respectively located in the plurality of mounting holes 471 to ensure the height of the ground of the trolley during the moving process; and the crusher when the broken trolley reaches the designated working position When work is required, the hydraulic pump station and the oil cylinder are started, the piston of the oil cylinder is extended downward, the driving base 470 is in contact with the ground to realize the installation of the base 470, and at the same time, the horizontal position is sought, and then the reaction force of the ground, the trolley and the base The 460 is topped to a certain height. At this time, the ladder wedge 480 is installed on the top of the inner wall of the corresponding mounting hole 471 through the first step wedge surface and the second ladder wedge surface, and the bearing surface and the support surface are in contact with each other. The base 460 is maintained at a corresponding height. After that, the cylinder is started again, the trolley is lowered, and the height of the base 460 is constant or the change is small. At this time, the base 460 and the trolley load beam 490 are separated from each other, so the vibration generated by the crusher operation is not transmitted to the trolley. The body, so that the trolley can be effectively protected from damage. When the crusher completes the specified position and the crushing work needs to be transferred to another working position, the oil cylinder is started, the trolley load beam is lifted, and the guide ball and the first support beam 410 and the second support beam are positioned by the reset on the load beam. The spherical guiding hole on the 420 automatically resets the working platform 400 carrying the crusher to the loading and carrying trolley load beam; meanwhile, the cylinder piston rod continues to extend the lifting trolley load beam and the body, the base 460 and the broken Fixation of machine to frame 460 When the legs 462 are separated from the base 470 to the respective ladder blocks 400, after the ladder block 400 is removed, the piston rod of the shrink cylinder is lowered to the trolley, the base 460 and the crusher are lowered to completely rely on the trolley tire support. After that, the piston rod of the oil cylinder is continuously contracted, and the first support base 430 and the second support base 440 are lifted. Under the guidance of the guide rod, the lifted first support base 430 and the second support base 440 of the trolley crusher work platform 400 are The lift is brought into close contact with the first support beam 410 and the second support beam to prepare for the transfer.

It should be noted that the height of the base 460 can be adjusted by adjusting the ladder wedge 480.
