Description

Technical Field

[0001] The utility model relates to the technical field of anchor rod auxiliary equipment, in particular to an anchor rod taking out device. Background Art

[0002] Anchor rod is an important engineering structural component, mainly used to reinforce and support rock and soil. It consists of a rod with high tensile strength, one end of which is connected to the engineering structure and the other end is deep in the stratum. It is divided into two parts: a free section and an anchor section. Anchor rods are widely used in mine tunnels, slopes, tunnels, dams and other projects. Through their longitudinal tension, they can improve the bearing capacity and stability of rock and soil.

[0003] Anchor rods are usually made of high-strength, high-rigidity materials, such as steel bars or steel bundles. These materials themselves have high tensile strength and stability. Therefore, once inserted into the rock and soil, they form a stable mechanical connection with the surrounding rock and soil, and friction is generated between the contact surface of the anchor rod and the rock and soil. This friction increases with the increase of the anchor rod length, resulting in the need to overcome this friction when the anchor rod is removed, making the removal process difficult. Therefore, the existing anchor rod removal device cannot adapt to different terrains to remove the anchor rod from the rock and soil layer. Utility Model Content

The insert block 12 is a cone structure, and the clamping groove 10 is provided on one side of the bottom plate 2, so that the bottom plate 2 can cooperate with the insert block 12 to contact the ground on one side of the anchor rod, so as to facilitate the operation of the screw rod 3;

[0023] like Figure 2 , Figure 4 As shown, a first fixed shaft 16 is fixedly installed on the top of the screw rod 3, and a screw groove 17 is opened at the center position of the top of the first fixed shaft 16, and the top of the screw rod 3 is also rotatably installed in the shaft seat at the top of the column 1. The rotatable screw rod 3 is set to control the lifting and lowering adjustment of the lifting rod 4. A sleeve block 13 is fixedly installed on one side of the lifting rod 4, and a screw hole 14 is opened in the sleeve block 13. A support rod 15 is also fixedly connected between the sleeve block 13 and the bottom of the lifting rod 4. The sleeve block 13 is threadedly connected to the screw rod 3 through the screw hole 14, and the lifting rod 4 and the rotary block 5 extend to the outside of the column 1 through the slide groove 9. The sleeve block 13 is controlled by the screw 3 to move up in the lifting groove 8, so as to cooperate with the lifting rod 4 and the support rod 15 to push the anchor rod up;

[0024] like Figure 2-Figure 3As shown, a socket 18 is provided in the rotary block 5, a fixed block 19 is fixedly installed on the outer side of the rotary block 5, a connecting groove 20 is provided in the fixed block 19, the rotary block 5 is inserted and installed on the first fixed shaft 16 through the socket 18, a connecting block 21 is fixedly installed on the top of the operating handle 7, a second fixed shaft 22 is fixedly installed in the connecting block 21, the connecting block 21 is rotatably installed in the connecting groove 20 through the second fixed shaft 22, a gasket 23 is fixedly installed on the outer side of the fixing screw 6, the bottom of the fixing screw 6 is threadedly connected in the screw groove 17, and the gasket 23 limits the upward movement of the rotary block 5.

[0025] It should be noted that the utility model is an anchor rod removal device. When the anchor rod is taken out from the rock and soil layer, the column 1 can be placed on the stratum on one side of the anchor rod end, and the plug block 12 is inserted into the stratum. At the same time, the card slot 10 on one side of the bottom plate 2 is inserted into the end of the anchor rod, so that the subsequent column 1 can be placed to undergo axial movement.

It is inserted and installed on the first fixed shaft 16 to drive the screw rod 3 to rotate, and then the screw rod 3 rotates in the shaft seat at the top of the column 1. At the same time, the screw rod 3 also rotates in the screw hole 14 of the sleeve block 13, so that the screw rod 3 controls the sleeve block 13 to move up, and the sleeve block 13 drives the screw hole 14 and the support rod 15 to move up. Therefore, as the sleeve block 13 and the screw hole 14 gradually move upward, the anchor rod can be pulled outward in cooperation with the fixing ring at the end of the anchor rod. As the anchor rod is pulled out, the friction layer formed by the rock and soil layer on the surface of the anchor rod may be gradually destroyed, resulting in a reduction in friction, thereby facilitating the rapid removal of the anchor rod.
