Description

Technical Field

[0002] Construction material transport vehicles are often used at construction sites to transfer construction materials. When using construction material transport vehicles to transport pipe-like construction materials, the pipes are easily displaced on the transport vehicle, causing the pipes to fall from the transport vehicle, which in turn affects the speed of transporting construction materials by the transport vehicle and increases the labor intensity of workers.

[0003] "A construction material transport device with publication number 'CN220430237U'" discloses that by setting two clamping plates, under the action of a first threaded rod and a second threaded rod, the first threaded rod and the second threaded rod are rotated, which can respectively drive the clamping plates to move synchronously on the top of the bottom plate, so that the two clamping plates can clamp and limit the pipes placed on the bottom plate, which can effectively prevent the pipes from falling from the transport vehicle and affecting the speed of the transport vehicle to transport construction materials, thereby effectively improving the practicality of the construction material transport vehicle. However, the above device fixes the screw hole block and the clamping block by bolts, and the bolts are located at the bottom of the vehicle, which is very inconvenient to rotate the bolts, and the operating blocks for adjusting the first threaded rod and the second threaded rod are also located at a lower position, and workers need to squat to operate to rotate, which is not very practical. Therefore, in order to solve the above problems, the present application provides a construction material transportation auxiliary clamping device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.
