Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to an anchor rod for construction and municipal administration. Background Art

[0002] Anchor rod is the most basic component of tunnel support in contemporary coal mines. It reinforces the surrounding rock of the tunnel so that the surrounding rock can support itself. Anchor rod is not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels, and dam bodies. As a tensile member deep in the stratum, one end of the anchor rod is connected to the engineering structure and the other end is deep in the stratum. When using the existing self-drilling hollow anchor rod, the hollow anchor rod is usually controlled to drive the end drill bit to rotate and insert into the stratum, and then concrete mortar is injected into the interior through the hollow anchor rod to perform support operations. In the process of supporting with self-drilling hollow anchor rods, when the anchor rod is deformed and fractured due to geological changes or load changes, which leads to support failure, it is not convenient for the staff to discover in time and take remedial measures for the support area. Therefore, a construction and municipal anchor rod is proposed to address the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

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

[0021] Example 2

[0022] like Figure 2 As shown, in order to solve the problem that it is inconvenient to insert the fixed shaft 11 into the sleeve 5 and connect it with the slider 7, the bottom end of the slider 7 is fixedly connected to the first spring 8, and the other end of the first spring 8 is fixedly connected to the sleeve 5. By making the slider 7 slide on the top inner side of the sleeve 5 under the elastic force of the first spring 8 when the fixed shaft 11 is connected to the slider 7, the slider 7 slides on the top inner side of the sleeve 5 under the elastic force of the first spring 8, which facilitates the insertion of the fixed shaft 11 into the sleeve 5 and the connection with the slider 7.

[0023] Example 3

[0024] like Figure 2-3 As shown, in order to solve the problem that it is inconvenient to position the fixed block 9 on the right side of the top end of the anchor rod 1, a fixed shaft 11 that penetrates the slide plate 10, the fixed block 9 and the second spring 13 is fixedly connected at the inner center of the slide plate 10, and the fixed shaft 11 is slidably connected to the fixed block 9, and the bottom of the fixed shaft 11 is spirally connected to the slider 7.

By making the signal light 15 evenly distributed in a ring shape on the outside of the anchor rod 1, it is convenient to observe the signal light 15 from different angles.

[0029] In this embodiment, when the device is used to support the stratum, the anchor rod 1 is first controlled to drive the drill bit 2 to drill into the stratum. When the pad 3 on the outside of the anchor rod 1 is in close contact with the ground under the obstruction of the nut 4, concrete is injected into the stratum through the anchor rod 1 and the drill bit 2. After completing the above operations, the fixing block 9 is rotated to make the bottom of the fixing shaft 11 and the slider 7 spirally connected together.

When the signal light 15 is damaged and cannot be used, the damaged signal light 1 glued to the anchor rod 1 can be taken out by pushing the glass cover 16 to compress the third spring 17. 5 is replaced. During the use of the device after replacement, when the anchor rod 1 is deformed and fractured after geological changes or load changes, resulting in support failure, the anchor rod 1 is deformed and fractured, and the concrete mortar and sleeve rod 5 solidified inside the anchor rod 1 are also broken. The steel cable 6 is subjected to tension, and then the steel cable 6 pulls the slider 7 to compress the first spring 8, and at the same time drives the slide plate 10 to stretch the second spring 13 through the fixed shaft 11. When the slide plate 10 slides and triggers the control switch 12 to start the signal light 15, after observing that the signal light 15 is on, it can be determined that the device is broken, which is convenient for the staff to find out in time and take remedial measures for the support area.
