Description

Technical Field

[0001] The utility model relates to the technical field of small carts, in particular to a small cart that can be moved in a tunnel. Background Art

[0002] The construction of a pumped-storage power station needs to be carried out in an environment with complex terrain and narrow working space. A large amount of mechanical equipment is needed for uninterrupted construction day and night. During cavern construction, the construction of a temporary power supply environment requires the installation of wires on the cave wall, which is extremely cumbersome when moving. It is necessary to re-plug the connectors, fix the wiring, and drag the wires, which can easily cause safety accidents and equipment damage, and delay the construction period. A small cart is needed to drive the distribution box to move in the tunnel. It can be moved to different construction sites according to the progress of the construction to supply energy to various devices so that they can operate normally, thereby avoiding the problem that the distribution box cannot move with the need for rewiring, which is slow in efficiency and has a high failure rate and is prone to safety accidents.

[0003] After searching, the Chinese patent application number 202321362638.0 discloses a mobile tunnel lighting trolley, including a trolley, a support frame and a lighting device. The support frame is installed on the trolley, and the lighting device is installed on the support frame. The lighting device includes an angle adjustment structure, a winding structure and an auxiliary support structure. The winding structure is installed on the support frame, the angle adjustment structure is installed on the support frame, and the auxiliary support structure is installed on the top of the support frame. The angle adjustment structure includes a lighting lamp, a positioning frame, a rotating seat, a positioning bolt and a locking bolt. The mobile tunnel lighting trolley in the above patent has the following shortcomings: when the device is in use, it is impossible to fix the power supply equipment such as the distribution box on the device to drive it to move. As the construction progresses, the power supply of the device needs to be rewired when the distribution box cannot be carried and moved, which will reduce the efficiency of construction and increase the incidence of safety accidents.
