Embodiment 1

[0052] Such as Figure 1-7 As shown, a kind of impact test device for the rod-shaped anchor assembly described in this embodiment,

[0053] Including base 1, support frame 4 and slidable plate 13, wherein,

[0054] The base 1 is used to place the rod-shaped anchor assembly 7 horizontally, and the base 1 is used to connect with the end of the rod-shaped anchor assembly 7 away from the support frame 4;

[0055] A pendulum 5 is hinged on the support frame 4;

[0056] A supporting sliding device 2 is arranged between the base 1 and the supporting frame 4, and the top of the supporting sliding device 2 is supported and connected with a force transmission frame 3, and the force transmission frame 3 is arranged horizontally, and the force transmission frame 3 is arranged along the The horizontal direction cooperates with the movement of the supporting sliding device 2, the end of the force transmission frame 3 close to the base 1 has a first end plate 31, and the end of the force t...

Embodiment 2

[0077] Such as Figure 1-9 As shown, the impact test device for the rod-shaped anchor assembly described in this embodiment is different from Embodiment 1 in that there are at least two seat plates 15, and the seat plates 15 are adjacent to each other. Arranged at intervals, all of the seat plates 15 are provided with fourth through holes 151 for the rod-shaped anchor assembly 7 to pass through, and all of the fourth through holes 151 are coaxially arranged with the first through holes 131 .

[0078] The seat board 15 is connected with the support 12 through a connecting rod 16, and the connecting rod 16 runs through all the seat boards 15, and the two sides of the slidable plate 13 are provided with screws that are threadedly connected with the connecting rod 16. A sleeve 17, one end of the connecting rod 16 is connected with the support 12.

[0079] In the test, the most ideal state is that the first through hole 131, the second through hole 311, the third through hole 121 ...

Abstract

The invention relates to the field of anchoring engineering tests, in particular to an impact test device for a rod-shaped anchoring assembly. The device comprises a base and a supporting frame, and apendulum bob is hinged to the supporting frame. A supporting sliding device is arranged between the base and the supporting frame, a force transmission frame is connected to the top of the supportingsliding device in a supporting mode and movably matched with the supporting sliding device in the horizontal direction, a first end plate is arranged at the end, close to the base, of the force transmission frame, a second end plate is arranged at the end, away from the base, of the force transmission frame, and the pendulum bob can horizontally impact the second end plate in the direction away from the base. According to the impact test device for a rod-shaped anchoring assembly, an impact load test can be conducted on the rod-shaped anchoring assembly when the rod-shaped anchoring assemblyis horizontally arranged, then the cost of the impact load test is reduced, an operator does not need to go to a high place for operation, the operation is convenient, the test difficulty is low, thesafety risk coefficient is low, and an impact test can be carried out on a long anchor rod.

Description

technical field [0001] The invention relates to the field of anchor engineering tests, in particular to an impact test device for rod-shaped anchor components. Background technique [0002] At present, the rod-shaped anchoring components (bolt or anchor cable) used in engineering are widely used in slope reinforcement, tunnel and mine roadway support, etc. Therefore, in the use of some projects, it is necessary to test and evaluate the impact resistance of anchor rods and anchor cables. [0003] However, the existing impact test device for the rod-shaped anchor assembly usually sets the rod-shaped anchor assembly vertically, and impacts the lower end of the rod-shaped anchor assembly downward through a special tool, so as to achieve the purpose of applying an impact load to the rod-shaped anchor assembly. [0004] However, the above scheme has the following disadvantages: [0005] 1. The impact test device needs to be equipped with a bracket at least as high as the rod-sha...
