Technical Field

[0001] This utility model relates to the field of anchor bolt technology, and in particular to an anchor bolt for mining engineering. Background Technology

[0002] Rock bolts are a commonly used support device in mining engineering. They are mainly used to enhance the stability of structures such as mine tunnels, shafts, and underground engineering projects. By connecting the underground rock mass with the support structure (such as steel frames, concrete linings, etc.), they play a reinforcing role. The application of rock bolts in mining engineering can effectively prevent geological disasters such as rock mass collapse and landslide, and ensure the safety of personnel and equipment.

[0003] Traditional rock anchors are installed by drilling holes in the rock strata and then using a drilling rig and anchoring machine. Pads, trays, and nuts are then attached to the anchors to provide support and reinforcement to the rock mass. However, in practice, it has been found that while the trays enhance the anchoring effect and ensure the integrity of the support system, the lack of connecting components between adjacent anchors affects the support effect and limits the use of rock anchors. Utility Model Content

[0004] The technical problem this utility model aims to solve is that while the tray enhances the anchoring effect and ensures the integrity of the support system during the use of anchor bolts, the tray lacks corresponding connecting parts between adjacent anchor bolts, which affects the support effect of the anchor bolts and limits their use.

[0009] Preferably, the reinforcing device further includes a washer installed on the inner wall of the screw's arc surface, wherein the washer increases the reinforcing strength of the screw.

[0010] The effect achieved by the above components is that, by setting the washer, the screw will fit more snugly when it is installed through the side of the fixing rod, and it is not easy to rotate or loosen, thus ensuring the position of the fixing rod is firm.

[0011] Preferably, the reinforcement device further includes a reinforcement ring installed on the inner wall of the slot, wherein the reinforcement ring improves the connection stability between the fixing rod and the slot.

[0012] The effect achieved by the above components is that, through the setting of the rubber reinforcing ring, the U-shaped fixing rod is less likely to have gaps when it is inserted into the inner wall of the slot, and the contact friction is further improved, thereby ensuring a stable connection between the components.

[0013] Preferably, the inner wall of the adjusting plate is provided with a sliding groove, wherein a slider mounted on the surface of the connecting plate is slidably disposed on the inner wall of the sliding groove.

[0014] The effect achieved by the above components is that, through the setting of sliders and grooves, a stable connection is maintained between the adjusting plate and the connecting plate, preventing detachment and loosening, and ensuring the normal use of the device.

[0015] Preferably, the surface of the tray is provided with a stabilizing device, wherein the stabilizing device includes a pressure plate, and clamping plates are fixedly connected to both sides of the surface of the pressure plate, and bolts are inserted through the surface of the pressure plate, and the bolts are threadedly connected to the surface of the tray.

[0016] The effect achieved by the above components is that the position of the reinforcement device will be better maintained and less prone to abnormal loosening, thereby enabling the anchor bolt to provide better support for the rock mass.

[0017] Preferably, the stabilizing device further includes a throttle mounted on the bolt surface, wherein the throttle can assist in better installation and fixation of the bolt.

[0019] Preferably, the stabilizing device further includes a spring sleeved on the arc surface of the bolt, wherein the two ends of the spring are respectively connected and fixed to the tray and the pressure plate.

[0020] The effect achieved by the above components is that, through the setting of the spring, after the reinforcement device is assembled, the pressure plate can be pressed quickly onto the surface of the adjusting plate under the action of the spring force, thereby facilitating the subsequent installation and fixing of the device.

[0031] Figure 1 and Figure 2 The anchor bolt shown includes an anchor bolt body 1, with a pad 2 and a tray 3 fitted on the surface of the anchor bolt body 1. A nut 4 is threaded onto the arc surface of the anchor bolt body 1. The surface of the tray 3 is provided with a stabilizing device 6 and a reinforcing device 5. The reinforcing device 5 forms a certain connection between adjacent anchor bolt bodies 1 installed on the rock surface by means of an adjusting plate 53. The surface of the tray 3 is provided with a stabilizing device 6.

[0032] Figure 1 , Figure 2 and Figure 3The reinforcement device 5 shown includes a connecting plate 51, wherein adjusting plates 53 are slidably connected to both sides of the surface of the connecting plate 51, and the surface of the connecting plate 51 is provided with several evenly distributed slots 52. An installation shaft 54 ​​is rotatably mounted on one side of the adjusting plate 53, wherein the installation shaft 54 ​​is connected and fixed to the surface of the tray 3. Rotating shafts 55 are respectively mounted on both sides of the surface of the adjusting plate 53, wherein a fixing rod 56 is rotatably mounted on the arc surface of the two rotating shafts 55, wherein the fixing rod 56 is connected and fixed to the adjusting plate 53 by means of screws 57. When using anchor bolts to reinforce and support the rock mass in mining operations, firstly, several anchor bolt bodies 1 are evenly distributed in the installation holes on the surface of the rock mass according to the support requirements, and then the pad block 2, tray 3 and nut 4 are installed in sequence. On the arc surface of the anchor body 1, during the installation of adjacent trays 3, the adjusting plates 53 on the mounting shaft 54 ​​of the two trays 3 will slide with the same connecting plate 51 until the connection position is determined. Then, the fixing rod 56 on the arc surface of the rotating shaft 55 is rotated until the fixing rod 56 is engaged in the slot 52 on the surface of the connecting plate 51. Then, two screws 57 are respectively inserted through both sides of the surface of the fixing rod 56 until the screws 57 and the adjusting plate 53 form a threaded connection, thereby keeping the connecting plate 51 and the adjusting plate 53 stable and promoting the connection and fixation of adjacent trays 3. At this time, when the anchor is used, it can form a stable connection relationship between adjacent trays 3, thereby better supporting the rock mass, improving the use effect and functionality of the anchor, and also expanding the application range of the anchor.

[0033] Figure 1 , Figure 2 and Figure 3 The reinforcing device 5 also includes a washer 58 installed on the inner wall of the arc surface of the screw 57. The washer 58 increases the reinforcing strength of the screw 57. The washer 58 ensures a closer fit when the screw 57 is installed through the side of the fixing rod 56, preventing loosening and ensuring the fixing rod 56 is firmly positioned. The reinforcing device 5 also includes a reinforcing ring 511 installed on the inner wall of the slot 52. The reinforcing ring 511 improves the connection stability between the fixing rod 56 and the slot 52 through the reinforcement of rubber material. The ring 511 is designed to prevent gaps from forming when the U-shaped fixing rod 56 is inserted into the inner wall of the slot 52, and to further increase the contact friction, thereby ensuring a stable connection between the components. The inner wall of the adjusting plate 53 is provided with a sliding groove 510, in which a slider 59 is slidably mounted on the surface of the connecting plate 51. Through the arrangement of the slider 59 and the sliding groove 510, a stable connection is maintained between the adjusting plate 53 and the connecting plate 51, preventing detachment and loosening, and ensuring the normal use of the device.

[0034] Figure 1 , Figure 2 and Figure 4The stabilizing device 6 shown includes a pressure plate 62, with clamping plates 63 fixedly connected to both sides of the surface of the pressure plate 62. Bolts 61 are inserted through the surface of the pressure plate 62 and threadedly connected to the surface of the tray 3. When the tray 3 of the adjacent anchor body 1 on the rock mass is connected and fixed using the reinforcement device 5, the bolts 61 are first inserted through the surface of the pressure plate 62, and then the bolts 61 are threadedly connected to the surface of the tray 3, so that the nut of the bolts 61 contacts and presses against the pressure plate 62. This causes the clamping plates 63 fixedly connected to both sides of the surface of the pressure plate 62 to be clamped onto the surface of the adjusting plates 53 at the adjacent corners of the tray 3. At this time, the position of the reinforcement device 5 will be better maintained and less prone to abnormal loosening, thereby better enabling the anchor to support the rock mass.

[0035] Figure 1 , Figure 2 and Figure 4 The stabilizing device 6 shown also includes a handle 65 mounted on the surface of the bolt 61. The handle 65 can help the bolt 61 to be better installed and fixed. By rotating the handle 65, the bolt 61 can be pre-positioned on the surface of the tray 3, which facilitates the subsequent use of tools to reinforce the bolt 61. The stabilizing device 6 also includes a spring 64 sleeved on the arc surface of the bolt 61. The two ends of the spring 64 are respectively connected and fixed to the tray 3 and the pressure plate 62. By setting the spring 64, after the reinforcement device 5 is assembled, the pressure plate 62 can be pressed quickly onto the surface of the adjusting plate 53 under the elastic force of the spring 64, which facilitates the subsequent installation and fixing of the device.

[0036] Working principle: When using anchor bolts to reinforce and support rock masses during mining operations, several anchor bolt bodies 1 are first evenly distributed on the installation holes on the rock mass surface according to the support requirements. Then, the pads 2, trays 3, and nuts 4 are installed sequentially on the arc surface of the anchor bolt bodies 1. When installing adjacent trays 3, the adjusting plates 53 on the installation shaft 54 ​​of the two trays 3 will slide with the same connecting plate 51 until the connection position is determined. Then, the fixing rod 56 on the arc surface of the rotating shaft 55 is rotated until the fixing rod 56 is engaged in the slot 52 on the surface of the connecting plate 51. Then, two screws 57 are respectively inserted through the two sides of the surface of the fixing rod 56 until the screws 57 and the adjusting plate 53 form a threaded connection, thereby keeping the connecting plate 51 and the adjusting plate 53 stable and promoting the connection and fixation of adjacent trays 3. At this time, when the anchor bolt is used, it can form a stable connection relationship between adjacent trays 3, thereby better supporting the rock mass, improving the use effect and functionality of the anchor bolt, and also expanding the application range of the anchor bolt.

[0037] After the reinforcement device 5 is used to connect and fix the trays 3 of adjacent anchor bodies 1 on the rock mass, firstly, the bolts 61 are passed through the surface of the pressure plate 62, and then the bolts 61 are threaded onto the surface of the tray 3, so that the nut of the bolts 61 contacts and presses against the pressure plate 62, thereby causing the clamping plates 63 fixedly connected on both sides of the surface of the pressure plate 62 to be respectively clamped onto the surface of the adjusting plates 53 at the two adjacent corners of the tray 3. At this time, the position of the reinforcement device 5 will be better maintained and less prone to abnormal loosening, thereby making the anchors better support the rock mass.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
