Description

Technical Field

[0001] The utility model relates to the technical field of bolt protection, in particular to a mining bolt installation and fixing device. Background Technique

[0002] Bolts are the most basic components for roadway support in contemporary coal mines. They reinforce the surrounding rock of the roadway together, enabling the surrounding rock to support itself. Now, bolts are not only used in mines but also in engineering technology to mainly reinforce slopes, tunnels, and dams. As a tension member that penetrates deep into the ground, one end of the bolt is connected to the engineering structure, and the other end penetrates deep into the ground. The whole bolt is divided into a free section and an anchorage section. The free end refers to the area that transmits the tension at the bolt head to the anchor body, and its function is to apply prestress to the bolt. An installation device is required during the installation process of the bolt.

[0003] The Chinese Patent Network discloses a mining bolt installation device with the publication number CN211081920U. Although the spherical adjustment blocks on the two crossbars are movably abutted in the three-quarter spherical grooves of the installation block, they can not only be used to support the installation block, but also the installation block can rotate in the spherical adjustment block by using the grooves, with stronger flexibility; by setting a red ink droplet in the vacuum transparent tube fixedly embedded in the installation block, the vertical position of the installation block is detected through the position of the red ink droplet in the vacuum transparent tube. However, the length of the support rod cannot be adjusted, making it unable to adapt to different terrains for use, and its practicability is not high.

[0004] Therefore, a mining bolt installation and fixing device is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a mining bolt installation and fixing device.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A mining bolt installation and fixing device, comprising:

[0008] An installation plate and a through hole opened at one end of the installation plate;

[0009] A regulating member is arranged on the rear end surface of the installation plate. The regulating member includes a regulating sleeve fixed on the rear end surface of the installation plate. An adjusting rod is arranged inside the regulating sleeve. One end of the adjusting rod is fixed with a connecting plate, and one end of the connecting plate is fixed with a sharp fixing rod.

[0010] Preferably, an adjusting rotating shaft is fixed on the outer wall of the adjusting rod.

[0011] Preferably, an internal thread is arranged on the inner wall of the regulating sleeve, and an external thread is arranged on the outer wall of the adjusting rod. The adjusting rod is threadedly connected inside the regulating sleeve through the external thread cooperating with the internal thread.

[0012] Preferably, two sliding grooves are symmetrically formed on the front surface of the mounting plate, sliders are installed in both of the two sliding grooves, and clamping plates are fixed to one ends of both of the two sliders.

[0013] Preferably, anti-slip protrusions are provided at one ends of the two clamping plates facing each other.

[0014] Preferably, receiving plates are fixed to one ends of the two clamping plates away from each other, connection holes are formed on the front surface of the receiving plates, and clamping holes are formed on the front surface of the mounting plate;

[0015] A long rod is movably arranged in the connection hole, an auxiliary plate is fixed to one end of the long rod, and one end of the long rod is clamped inside the clamping hole;

[0016] A U-shaped rod is fixed to one end of the auxiliary plate;

[0017] A spring is arranged on the outer wall of the long rod, one end of the spring is fixed to the auxiliary plate, and the other end of the spring is fixed to the receiving plate.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] Since the adjusting rod is connected to the adjusting sleeve by external threads matching internal threads, the adjusting rod can be driven to move inside the adjusting sleeve by adjusting the rotating shaft, so as to adjust the overall length of the adjusting rod and the adjusting sleeve, so that the sharp fixing rod can meet the use requirements of different terrains. Compared with the existing ones, the present utility model can adjust the length of the adjusting rod and the adjusting sleeve, so that the sharp fixing rod can meet the use requirements of different terrains, and has high practicability.

[0020] In the present utility model, by driving the two clamping plates to move towards each other, after the two clamping plates are in contact with the mining bolt, the long rod will be driven to move under the action of the spring. After one end of the long rod is clamped inside the clamping hole, the two clamping plates can be fixed, and the two clamping plates can limit the mining bolt to prevent the mining bolt from rotating, thereby improving the connection stability of the mining bolt.

Compared with the existing ones, the present utility model can adjust the length of the adjusting rod 4 and the adjusting sleeve 3, so that the sharp fixing rod 6 can meet the use requirements of different terrains, and has high practicability;

[0036] Second, by driving the two clamping plates 12 to move towards each other. After the two clamping plates 12 are in contact with the mining bolt, under the action of the spring 20, the long rod 17 will be driven to move. After one end of the long rod 17 is clamped inside the clamping hole 16, the two clamping plates 12 can be fixed. The two clamping plates 12 can limit the mining bolt to prevent the mining bolt from rotating, thereby improving the connection stability of the mining bolt.
