[0002] During the subway underground excavation construction process, concrete pump trucks are often used for pouring concrete due to the influence of the construction site. During the delivery process of the concrete pump, as the pumping pressure increases, the pumping impact force will force the pipe to move back and forth, which not only consumes the pumping pressure, but also puts the connection parts between the pump pipes in a state of impact and intermittent tension, which can cause premature damage to the pipe clamps and rubber rings, and cement slurry overflow. What's worse, because the concrete pump pipe is not firmly fixed, it causes certain safety hazards. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a concrete pump pipe fixing device, which can firmly fix the pump pipe, reduce the shaking and deformation of the pump pipe during transportation, meet the requirements of cyclic use, and provide effective protection for the pump pipe.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Positioning holes are arranged at the four corners of the bottom plate, and positioning bolts are arranged in the positioning holes.

[0007] The pipe rack assembly includes an upper pipe clamp and a lower pipe clamp, which are symmetrically arranged. The lower pipe clamp is externally connected to a lower connecting cover, which adopts a rectangular frame structure. Connecting screws are arranged on both sides of the lower connecting cover. The upper pipe clamp is provided with screw holes corresponding to the connecting screws, and the lower connecting cover is connected to the ball joint assembly.

[0008] Anti-collision cushion layers are arranged on both sides of the bottom of the lower connecting cover.

[0009] The damping spring shock absorbers are arranged corresponding to the four corners of the lower connecting cover.

[0010] A shock absorber positioning groove is arranged below the lower connecting cover at a position corresponding to the damping spring shock absorber, and the shock absorber positioning groove is a circular groove.

[0011] The ball joint assembly includes a ball joint body and a mounting plate, wherein the mounting plate is fixedly arranged on the base plate, the ball joint body is fixedly arranged on the mounting plate, a limiting plate is arranged on the top of the ball joint body, a ball joint screw is arranged above the limiting plate, and the ball joint body is connected to the lower connecting cover via the ball joint screw.

[0013] The inner arc surfaces of the upper pipe clamp and the lower pipe clamp are both provided with a buffer wear-resistant layer.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The setting of the lower connection cover satisfies the connection between the pipe rack assembly and the ball joint assembly, so that the pipe rack assembly can meet the deflection in any direction. The setting of the damping spring shock absorber absorbs the shaking of the pipe rack assembly and ensures the stability of the pump pipe.
