At the same time, when in use, the linear displacement of the laser detection end can be accurately detected by the laser distance sensor and the infrared transceiver.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: the retaining wall casting trolley in the existing technology is located on both sides of the river channel, but there are no multiple passages reserved for people to go up and down, which makes it inconvenient and unsafe for people to go up and down, and cannot support multiple people to work up and down at the same time, and people need to queue up to go up and down. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problem that the retaining wall casting trolley in the prior art is located on both sides of the river channel, but there are no multiple passages for people to go up and down, which makes it troublesome and unsafe for people to go up and down, and cannot support multiple people to go up and down at the same time. The up and down people need to queue up, and a U-shaped variable-section intelligent mobile trolley is provided.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The U-shaped variable-section intelligent mobile trolley described in the utility model includes a sleeper track; a traveling wheel box is slidably connected to the sleeper track; a lower longitudinal beam is fixedly connected to the traveling wheel box; a plurality of portal columns are fixedly connected to the lower longitudinal beam; a portal upper crossbeam is fixedly connected to the portal column; a plurality of telescopic oil cylinders are symmetrically connected to the portal column; and a template unit is externally connected to the telescopic oil cylinder.

[0008] The U-shaped variable section intelligent mobile trolley provided by the utility model has the following beneficial effects:

[0009] 1. The utility model can change the position of the template unit through the reciprocating action of the telescopic cylinder, so that it can be adjusted according to the width of the U-shaped retaining wall. At the same time, people can get on and off the two sides of the template unit. The inner and outer assembly templates cooperate with the support rod assembly to form a fixed interval shape position, and then pour concrete to form the U-shaped retaining wall.

[0010] 2. The utility model uses an upper walking platform, a middle walking platform and a lower walking platform in conjunction with a ladder, making it more convenient for personnel to move up and down, and can facilitate the assembly and disassembly of the inner assembly template and the outer assembly template.
