Description

Technical Field

[0001] The invention relates to the technical field of bridge engineering, in particular to an automatic simple door machine and a use method thereof. Background Art

[0002] The current simple gantry crane for transportation is equipped with a high-power engine. All the mechanisms are hydraulically driven and wirelessly remotely controlled. The main mechanisms are composed of three parts: the lifting mechanism, the trolley running mechanism and the carriage running mechanism. Usually, the normal working operation steps are as follows: first, the lifting action is controlled to start the starting mechanism and lower the empty hook to the appropriate position. Then the lifting device raises the object to the appropriate height, and then the trolley running mechanism and the carriage running mechanism need to be started to the predetermined position before stopping. After that, the lifting mechanism is started again to lower the object, and then the empty hook is raised to the appropriate height, and the trolley running mechanism and the carriage running mechanism are controlled to run to the original position, so as to prepare for the next lifting work. Each time the transport of the object is completed, the previous process is repeated, and this working process is regarded as a cycle. In the same cycle, each mechanism is not working at the same time. Generally, when this mechanism is working, other mechanisms are stopped, but each mechanism must perform at least one forward operation and one reverse operation.

[0003] In the prior art, after the simple transport gantry crane is hoisted, the equipment is loaded onto a vehicle. Since the existing transport gantry cranes are fixed and cannot be lifted up or folded, when the transport vehicle passes through a tunnel, the existing transport gantry crane is relatively high, which will cause the transport vehicle to be too high when passing through the tunnel and cannot pass through. As a result, the vehicle needs to be disassembled after use and needs to be reinstalled when used, which is very inconvenient. A large amount of manpower and material resources are required when lifting the transport gantry crane, and since the gantry crane is relatively high, it is not easy to lift.
