[0028] The following further describes the embodiments of the present utility model with reference to the drawings.

[0029] Embodiment:

[0030] As shown in Figure 1 the figure, a slope anchorage quality inspection mechanism includes a bottom plate 1, a lifting plate 2, a cylinder 3, a clamping assembly, a constant pressure tank and an air pump (the constant pressure tank and the air pump are not shown in the attached drawings). Specifically, the bottom plate 1 is an equilateral triangle structure, and a first through hole 4 is provided in the middle of the bottom plate 1. The lifting plate 2 is also an equilateral triangle structure, and a second through hole 5 is provided in the middle of the lifting plate. The side length of the lifting plate 2 is smaller than the side length of the bottom plate 1. Both the first through hole 4 and the second through hole 5 are circular, and the diameter of the first through hole 4 is equal to the diameter of the second through hole 5.

[0031] One cylinder 3 is respectively provided at three corners of the lifting plate 2. Among them, the cylinder body end of the cylinder 3 is fixedly arranged on the bottom plate 1, and the piston rod end of the cylinder 3 is fixedly arranged on the lifting plate 2. The three cylinders 3 are respectively communicated with the constant pressure tank through a pipeline. The constant pressure tank is a hollow closed structure, and a pressure sensor is arranged in the constant pressure tank.

[0032] In addition, the constant pressure tank is also communicated with the output end of the air pump through a pipeline, and a one-way valve is provided on this pipeline.

[0033] The above clamping assembly is arranged on the lifting plate 2, and three clamping assemblies are arranged around the circumference of the second through hole 5, and the clamping ends of the clamping assemblies are located on the second through hole 5.

[0034] In this embodiment, a first through hole 4 is opened on the bottom plate 1, and a second through hole 5 is provided in the middle of the lifting plate 2, so that the end of the anchor outside the rock layer or soil layer passes through the first through hole 4 and the second through hole 5, and then the anchor is clamped by the cooperation of the clamping ends of all the clamping assemblies. Then, the air pump is used to inflate all the cylinders 3, and the lifting plate 2 is driven to move through all the cylinders 3, so as to drive the clamping assembly to move through the lifting plate 2, and further pull the anchor.

[0035] In this technical solution, the anchor is clamped and fixed by all the clamping assemblies, and then the movement of the clamping assembly is driven by the cylinder 3, so that the force driven by the cylinder 3 is consistent with the length direction of the anchor, so that the data measured by the pressure sensor in the constant pressure tank has a high accuracy.

[0036] In one specific embodiment:

[0037] The clamping assembly includes a support plate 6, a first screw 7, a pressing plate 8 and a hexagonal bolt head 9. Specifically, the support plate 6 is fixedly arranged on the lifting plate 2 and is located on the side of the lifting plate 2 away from the cylinder 3.

A pressing plate 8 is rotatably connected to one end of the first screw rod 7, such that the pressing plate 8 is located in the second through hole 5. Preferably, a side surface of the pressing plate 8 away from the first screw rod 7 is an arc surface. A hexagonal bolt head 9 is provided at the other end of the first screw rod 7.

[0039] In this embodiment, the first screw rod 7 can be directly rotated through the hexagonal bolt head 9, and then the first screw rod 7 moves on the support plate 6 to drive the pressing plate 8 to move on the second through hole 5. Through the cooperation of the pressing plates 8 on all the clamping assemblies, the purpose of clamping the anchor is achieved. In addition, the pressing plate 8 and one side surface of the anchor are provided with an arc surface structure, which can increase the contact area between the pressing plate 8 and the anchor, thereby enhancing the friction force between the pressing plate 8 and the anchor. At the same time, anti-slip lines can also be provided on the side of the pressing plate 8 with an arc surface.
