[0002] Tunnel reinforcement binding is the process of binding and fixing the steel bars together according to the design requirements before pouring concrete in the tunnel project to form a grid-like structure, making the concrete more solid and durable. Therefore, a trolley is required for tunnel reinforcement binding.

[0003] For example, the publication number CN217300601U discloses a new type of steel bar trolley that is convenient for steel bar binding, including a trolley bracket, a first operating platform arranged on the top of the trolley bracket, and is characterized in that it also includes a steel bar binding auxiliary component arranged on the first operating platform, and the steel bar binding auxiliary component includes at least two slide rails longitudinally arranged on the first operating platform, a sliding component embedded in the track of the slide rail and capable of sliding freely, a telescopic rod vertically fixed on the top of the pulley sliding component and capable of freely adjusting the length, and a steel bar clamping groove arranged on the top of the telescopic rod. The device is simple and easy to operate, and can reduce the number of workers and reduce costs while controlling the quality of steel bar binding, and can also Adjusting the height and position according to needs can solve the problem of uneven spacing between steel bar binding and improve the quality of steel bar binding connection. However, the trolley still has other shortcomings when in use. First, the trolley is provided with a steel bar slot on the telescopic rod to realize the placement of the steel bars. Since the steel bars will inevitably be touched during the binding process, the simple slot setting makes the limiting and fixing effect of the steel bars general, and there is a possibility that the steel bars will move out of the slot. The height of the steel bars is adjusted by the telescopic rod, but since it does not have a unified structure, the height of the steel bars cannot be guaranteed to be the same. Therefore, there are still certain shortcomings when using the device. Utility Model Content
