What's the reason for the mechanical crane graft track? How? After a gnawing failure in a mechanical crane, a detailed examination of the gnawing should be made and the relevant dimensions measured. A comprehensive analysis will allow for the identification of the reasons for the mechanical cranes and the recovery programme。
(1) adjustments to the large vehicle orbit shall be made to the height, extent and straightness of the orbital markers in strict accordance with the technical requirements, and shall be checked for bolt securing, semi-annually. The wheel-eating orbit occurs mostly in a fixed segment of the orbit and should be replaced in a timely manner if necessary。
(2) when driven individually, a cone-driven wheel is used, with the large end of the wheel being placed inside. If the car goes wrong, the diameter of the front-drive wheel group becomes smaller and the diameter of the back-drive group becomes larger. At the same speed, the rear wheel group travels at a very long distance, so the bridge automatically runs straight. Reduction in the diameter error of the side of the mechanical crane-driven wheel, increase in the hardness of the surface of the wheel and reduce the wear and tear on the pedal; it is important to check the diameter of the wheel。
(3) it is more difficult to repair the trajectories caused by the deformation of the bridge, using flame correction or pre-responding methods. By repositioning the wheel, it is possible to reduce the length of the wheel and the size error of the diagonal line caused by the deformation of the bridge, which is a solution to correct this chewing path。
(4) adjustment of the transmission structure of the bus. In the walk-through agency transmission system, the possible link parts of the system are checked for maintenance because of errors caused by wear and tear of the parts. For example, check gear wear and tear in brakes and coxes, the gap between keys and slots, and the blockage of the coxlear. The repair or replacement of spare parts is then considered. When a single-drive bus operator starts and stops at the same time as a power or brake failure, electrical failure shall be removed, the electric machine repaired or the brake readjusted。
The key to preventing mechanical crane wheels from eating tracks is to enhance security checks on wheels and steel tracks。
The processing and installation of mechanical cranes and cranes shall be within the permitted margin of error. The rolling plane should be flattened without too many defects. Note whether the frame is deformed, strictly control the parallelity, straightness and dichotomy of the wheel, and conduct visual inspections of steel tracks on a regular basis. If cracks, corrosions or bolts are found in the steel tracks, the plywood is loose and should be processed in a timely manner. Oil pollution and ice on steel tracks should be cleaned up in a timely manner, and the link should remain intact and should not be subject to relocation or runoff. The extent, parallelity, etc. Of the two parallel tracks should be checked periodically. The altitude differential is measured and adjusted. Practice has shown that, while mechanical cranes can cause a great deal of harm to us, when we find out why we are chewing on the tracks, it is possible to enhance the targeting of equipment。
