Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolt installation, in particular to an installation device for mining anchor bolts. Background Art

[0002] Anchor rods are the most basic component of tunnel support in modern coal mines. They reinforce the surrounding rock of the tunnel so that the surrounding rock can support itself. Now anchor rods are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels and dams. Anchor rods need to be installed with an installation device.

[0003] During installation, the existing anchor rod installation device only uses a rotating motor to directly drive the anchor rod into the terrain facing the terrain. During the rotation process, due to the lack of corresponding limiting facilities, the anchor rod will deviate during the rotation process, and the angle at which it is inserted into the terrain will also deviate to varying degrees. Its support effect will be weaker than expected as the deviation occurs, thereby causing the bearing capacity to weaken and causing landslides that endanger the lives of construction workers. Some anchor rod installation devices with limiting facilities have only fixed inner diameters. When installing thinner anchor rods, their limiting facilities are basically ineffective, and there will still be a situation where the bearing capacity is weakened and landslides occur that endanger the lives of construction workers. Utility Model Content

[0004] In order to solve the above-mentioned problem of how to stably limit the end of anchor rods with different diameters that needs to be inserted into the terrain, the utility model provides a mounting device for mining anchor rods.

By adjusting the position between the two limiting rollers, anchors of different diameters can be limited.

[0007] Furthermore, a slide groove is provided on the support plate, a driving screw is installed in the slide groove, a first motor is provided at one end of the driving screw, a driving nut moving along its axis is provided at the other end, and the driving nut is connected to the connecting block, so as to drive the locking mechanism to move toward the limiting roller to install the anchor rod.

[0008] Furthermore, a second motor is provided on the connection block, and an output shaft of the second motor is connected to the locking mechanism to rotate the locking mechanism, so as to drive the locking mechanism to rotate, thereby screwing the anchor rod into the position where the anchor rod needs to be installed.

[0009] Furthermore, the locking mechanism includes a locking sleeve connected to the second motor, an arc plate and a first screw, a plurality of arc plates are installed on the outer peripheral wall of the locking sleeve through the first screw, the arc plates are located inside the locking sleeve and can move along the radial direction of the locking sleeve, so as to facilitate locking of anchor rods of different diameters and drive the installation of anchor rods of different diameters.

[0010] Furthermore, a handle is provided on one end of the first screw rod located outside the locking sleeve, and the handle is used to conveniently screw the first screw rod to adjust the distance between the arc-shaped plates, thereby adapting to anchor rods of different diameters.

[0011] Furthermore, the limiting mechanism further comprises a vertical plate connected to the support plate and a limiting hole provided on the vertical plate, wherein the hole can be used as a guarantee for receiving the anchor rod after the limiting roller breaks.

[0012] Furthermore, the installation block is connected to a connecting rod of an L-shaped structure, and a rotatable limiting roller is mounted on the connecting rod. When the anchor rod is squeezed and limited between the two limiting rollers, the limiting roller can rotate, which is convenient for the installation of the anchor rod.

[0013] Furthermore, a handle is detachably mounted on the top of the active screw rod, and the handle can be used to drive the active screw rod to rotate, thereby achieving the two limiting rollers to move closer to or farther from each other.

[0014] Furthermore, a plurality of adjustment feet are provided on one side of the support plate away from the locking mechanism, and the adjustment feet are respectively located at the corners of the support plate, so as to facilitate the adjustment of the horizontality of the support plate.

[0028] The exemplary embodiments of the present disclosure will be described in more detail below in conjunction with the accompanying drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0029] Example

[0030] This embodiment provides a mounting device for a mining bolt, see Figure 1-Figure 4 , including a support plate 1 and a connecting block 4 that moves along the length direction of the support plate 1, the connecting block 4 is provided with a rotatable locking mechanism, the locking mechanism clamps the anchor rod, and a limiting mechanism is provided on the side of the support plate 1 away from the locking mechanism; the limiting mechanism includes an active screw 5, a driven screw 6, a gear 7, a mounting block 8, a limiting roller 9 and two guide rods 10, the active screw 5, the driven screw 6 and the two guide rods 10 are respectively provided with mounting blocks 8, a limiting roller 9 for limiting the anchor rod is provided between the mounting block 8 on the active screw 5 and the mounting block 8 on one of the guide rods 10, and a limiting roller 9 for limiting the anchor rod is also provided between the mounting block 8 on the driven screw 6 and the mounting block 8 on the other guide rod 10, the active screw 5 drives the driven screw 6 to rotate in the opposite direction through the gear 7, so that the limiting rollers 9 connected to different guide rods 10 can approach or move away from each other. By adjusting the position between the two limiting rollers 9, anchor rods with different diameters can all be limited.

[0031] By rotating the active screw 5, the mounting block 8 mounted on the active screw 5 can be driven to move up and down, and the mounting plate on the guide rod 10 matched therewith moves up and down synchronously with the mounting plate on the active screw 5. Since the bottom end of the active screw 5 is connected to the driven screw 6 through the gear 7, when the active screw 5 drives the mounting block 8 to move up and down, since the driven screw 6 rotates in opposite directions to the active screw 5, the mounting block 8 on the driven screw 6 moves in the opposite direction to the mounting block 8 on the active screw 5. Similarly, the mounting block 8 on the guide rod 10 matched with the mounting block 8 moves up and down with it;

[0032] When one end of the anchor rod is placed between the upper and lower limiting rollers 9, the distance between the upper and lower limiting rollers 9 can be adjusted by rotating the active screw rod 5, so that the two limiting rollers 9 are in contact with the anchor rod to be installed, ensuring that the two limiting rollers 9 can effectively limit the anchor rod to be installed, and by installing the other end of the anchor rod inside the locking mechanism and moving the connecting block 4, the anchor rod on the locking mechanism can be driven to move, and cooperate with the limiting rollers 9, so that anchor rods of different diameters can be effectively limited, so that the angle will not be offset when the anchor rod is installed, ensuring the accuracy of the anchor rod installation angle.

[0033] The support plate 1 is provided with a slide groove 2, in which a driving screw is installed, one end of the driving screw is provided with a first motor 11, and the other end thereof is provided with a driving nut 3 moving along its axis, and the driving nut 3 is connected to the connecting block 4. It is convenient to drive the locking mechanism to move toward the limiting roller 9 to install the anchor rod.

[0034] The first motor 11 can drive the driving screw to rotate. Since a driving nut 3 is installed on the driving screw, when the driving screw rotates, the position of the driving nut 3 changes with the rotation of the driving screw. Since the driving nut 3 is connected to the locking mechanism through the connecting block 4, the locking mechanism can be moved on the support plate 1, which is convenient for installing the anchor rod.

[0035] The connecting block 4 is provided with a second motor 12, and the output shaft of the second motor 12 is connected to the locking mechanism to rotate the locking mechanism, so as to drive the locking mechanism to rotate, thereby screwing the anchor rod into the position where the anchor rod needs to be installed.

[0036] Since the installation is divided into direct insertion and screw-in installation, when the anchor rod needs to be screwed in, the second motor 12 drives the locking mechanism to rotate, thereby driving the anchor rod to be installed to rotate and screwing the anchor rod into the position where it needs to be installed.

[0037] The locking mechanism includes a locking sleeve 13 connected to the second motor 12, an arc plate 14 and a first screw 15. A plurality of arc plates 14 are installed on the outer peripheral wall of the locking sleeve 13 through the first screw 15. The arc plates 14 are located inside the locking sleeve 13 and can move along the radial direction of the locking sleeve 13. It is convenient to lock anchor rods of different diameters and drive anchor rods of different diameters to be installed. A handle 16 is provided on one end of the first screw 15 located outside the locking sleeve 13. The handle 16 is convenient to screw the first screw 15 and adjust the distance between the arc plates 14 to adapt to anchor rods of different diameters.

[0038] By turning the handle 16, the operator can drive the first screw 15 to rotate, so that the positions of the multiple arc plates 14 can be changed, so that anchor rods of different diameters can be installed and locked inside the locking sleeve 13, thereby achieving the effect of locking anchor rods of different diameters and facilitating the installation of anchor rods of different diameters.

[0039] The limiting mechanism also includes a vertical plate 17 connected to the support plate 1 and a limiting hole 18 opened on the vertical plate 17. The diameter of the limiting hole 18 is the same as the maximum diameter of the anchor rod that can be limited by the limiting roller 9, and the limiting hole 18 can be used as a guarantee for receiving the anchor rod after the limiting roller 9 breaks.

[0040] The mounting block 8 is connected to a connecting rod 19 of an L-shaped structure, and a rotatable limiting roller 9 is mounted on the connecting rod 19. When the anchor rod is squeezed and limited between the two limiting rollers 9, the limiting rollers 9 can rotate, which is convenient for the installation of the anchor rod.

[0041] The limiting roller 9 can rotate. When the anchor rod to be installed is completely restricted between the upper and lower limiting rollers 9, the two limiting rollers 9 can not only limit the position of the anchor rod, but also because the limiting rollers 9 can rotate, when the locking mechanism drives the anchor rod to penetrate into the terrain, the limiting rollers 9 can rotate, reducing the friction force of the limiting rollers 9 on the anchor rod, making it easier for the limiting rollers 9 to quickly complete the installation work.

[0042] The top of the active screw rod 5 is detachably provided with a turning handle 20. The active screw rod 5 can be driven to rotate by turning the handle 16, and the active screw rod 5 can drive the driven screw rod 6 to rotate through the gear 7, thereby realizing that the two limiting rollers 9 are close to or away from each other.

[0043] A plurality of adjustment feet are provided on one side of the support plate 1 away from the locking mechanism, and the adjustment feet are respectively located at the corners of the support plate 1. This facilitates adjustment of the horizontality of the support plate 1. A level is provided in the horizontal direction of the support plate 1. This facilitates intuitive observation of the angle of anchor rod installation and timely adjustment of the anchor rod angle.

[0044] The angle of the support plate 1 can be adjusted by adjusting the legs, and the effect of the angle adjustment can be quickly and accurately identified by a level meter, making it easy to drive the anchor rod into the terrain at a required angle.

[0045] In this embodiment, the working principle of the installation device for mining bolts is as follows:

[0046] First, adjust the angle of the support plate 1 by adjusting the support feet and the spirit level to ensure that the required installation angle is reached; then, insert one end of the anchor rod into the locking sleeve 13, and adjust the arc plate 14 by turning the handle 16 to achieve the fixing effect on the end of the anchor rod, and the other end of the anchor rod is inserted between the two limiting rollers 9; then, by rotating and adjusting the active screw 5 to rotate, the active screw 5 drives the driven screw 6 to rotate in the opposite direction, so that the two limiting rollers 9 move toward or relative to each other, ensuring that the anchor rod is completely clamped between the two limiting rollers 9; finally, through the operation of the first motor 11, the driving screw is driven to rotate, and the locking mechanism installed on the driving nut 3 through the connecting block 4 can move in the direction of the two limiting rollers 9 to achieve the installation of the anchor rod. When a screw-in installation is required, the second motor 12 is used to drive the anchor rod to rotate, thereby achieving the screw-in installation of the anchor rod.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
