Description

Technical Field

[0001] This utility model relates to the field of mine shaft and tunnel technology, specifically to an anchor bolt tray for mine shaft and tunnel support. Background Technology

[0002] Rock bolts are a fundamental component of roadway support in modern coal mines. They reinforce the surrounding rock, allowing it to support itself. During installation, rock bolt trays are used to limit their position. However, existing rock bolt trays are usually installed directly on the roadway wall. The connection between the tray and the wall is easily affected by the unevenness of the wall, which can compromise the limiting effect of the tray. The current solution is to fill the gap between the tray and the wall with mortar, but this requires manual operation, which slows down the installation process. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide an anchor bolt tray for mine shaft and tunnel support. This solves the problem that existing anchor bolt trays are typically installed directly on the shaft wall during use. The unevenness of the shaft wall at the connection point can affect the anchor bolt tray's positioning effect. Current solutions involve adding mortar between the anchor bolt tray and the shaft wall, but this requires manual operation, reducing the installation speed of the anchor bolts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rock bolt tray for mine shaft support, comprising a rock bolt tray body, a ball head shaft installed in the middle of the rock bolt tray body, and a limiting groove hole opened on the inner side of the rock bolt tray body, a rubber gasket provided on the outer side of the rock bolt tray body, and a rock bolt nut provided on the outer side of the rubber gasket, a hollow rubber pad installed on the inner side of the rock bolt tray body, and buckles distributed along the inner axis of the hollow rubber pad, and a plug threadedly connected to the end of the ball head shaft away from the rubber gasket.

[0005] The beneficial effects of this utility model are as follows: during use, the hollow rubber pad seals the contact point between the anchor bolt tray body and the tunnel wall, ensuring the airtightness of the contact surface between the anchor bolt tray body and the tunnel wall, thereby ensuring the reliability and stability of the anchor bolt tray body during use. This method eliminates the need for mortar filling, ensuring the installation speed of the anchor bolt.

[0006] To facilitate the positioning and fixation of the anchor nut on the anchor tray body when the anchor bolt is in a horizontal or vertical state:

[0007] As a further improvement to the above technical solution, the number of rubber pads is two.

[0008] The beneficial effects of this improvement are: the two rubber gaskets can cooperate to form a washer with parallel upper and lower surfaces, which facilitates the anchor nut's positioning and fixation of the anchor tray body when the anchor rod is in a horizontal or vertical state.

[0009] To facilitate the limiting and fixing of the anchor bolt nut to the anchor bolt tray body when the anchor bolt is tilted:

[0010] As a further improvement to the above technical solution: the inner side of the rubber pad is inclined.

[0011] The beneficial effects of this improvement are as follows: when the anchor rod is in an inclined state, a rubber gasket is installed, with the inclined side fitting against the anchor rod tray body and the other side contacting the anchor rod nut, thereby facilitating the anchor rod nut to limit and fix the anchor rod tray body when the anchor rod is in an inclined state.

[0012] To facilitate the fit between the rubber gasket and the anchor plate body:

[0013] As a further improvement to the above technical solution: the rubber gasket and the anchor tray body are arranged with their centerlines aligned.

[0014] The beneficial effects of this improvement are: the centerline coincidence setting allows the rubber gasket to fit more tightly with the anchor tray body, which in turn facilitates the anchor nut to be used with the rubber gasket to fix the anchor tray body.

[0015] To facilitate the sealing of the anchor bolt tray body by the hollow rubber gasket:

[0016] As a further improvement to the above technical solution: the surface of the hollow rubber pad near the anchor bolt tray body is in close contact with the anchor bolt tray body.

[0017] The beneficial effects of this improvement are: by sealing the contact points between the anchor bolt tray body and the tunnel wall with a hollow rubber pad, the tight fit can ensure the fit between the hollow rubber pad and the contact surface of the anchor bolt tray body.

[0018] To facilitate the fixing of the hollow rubber pad:

[0019] As a further improvement to the above technical solution: the buckle and the limiting slot opened on the anchor rod tray body are engaged.

[0020] As a further improvement to the above technical solution: the buckles are circumferentially distributed on the hollow rubber pad.

[0021] The beneficial effects of this improvement are: the hollow rubber pad can be firmly installed on the anchor bolt tray body by means of the circumferentially distributed buckles and limiting slots, reducing alignment operations and making the installation of the anchor bolt tray body more convenient and faster.

[0022] To facilitate the screwing in of the ball joint:

[0023] As a further improvement to the above technical solution: the center line of the plug and the ball head shaft are arranged to coincide.

[0024] The beneficial effects of this improvement are: by aligning the plug with the axis of the ball head shaft, the angle between the ball head shaft and the anchor rod can be made the same during installation, and the position of the anchor rod tray body can also be limited.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0032] like Figure 1-5As shown, a bolt support tray for mine tunnel support includes a bolt support tray body 1. A ball head shaft 11 is installed in the middle of the bolt support tray body 1, and a limiting slot 12 is formed on the inner side of the bolt support tray body 1. A rubber gasket 2 is provided on the outer side of the bolt support tray body 1, and an anchor nut 3 is provided on the outer side of the rubber gasket 2. A hollow rubber gasket 4 is installed on the inner side of the bolt support tray body 1, and buckles 41 are distributed along the inner axis of the hollow rubber gasket 4. A plug 5 is threaded to the end of the ball head shaft 11 away from the rubber gasket 2. In use, the hollow rubber gasket 4 provides support between the bolt support tray body 1 and the tunnel wall. The anchor bolt tray body 1 is sealed at the contact point to ensure the airtightness of the contact surface between the anchor bolt tray body 1 and the tunnel wall, thereby ensuring the reliability and stability of the anchor bolt tray body 1 during use. This method eliminates the need for mortar filling, ensuring the installation speed of the anchor bolt. Two rubber gaskets 2 are used, which can cooperate to form a washer with parallel upper and lower surfaces, facilitating the limiting and fixing of the anchor bolt tray body 1 by the anchor bolt nut 3 when the anchor bolt is in a horizontal or vertical state. The inner surface of the rubber gasket 2 is inclined. When the anchor bolt is in an inclined state, one rubber gasket 2 is inserted, with the inclined surface in contact with the anchor bolt tray body 1 and the other surface in contact with the anchor bolt nut. The anchor nut 3 contacts the anchor tray body 1, thus facilitating the limiting and fixing of the anchor tray body 1 when the anchor is in an inclined state. The rubber gasket 2 and the anchor tray body 1 are arranged with their centerlines aligned. This alignment allows for a tighter fit between the rubber gasket 2 and the anchor tray body 1, facilitating the fixing of the anchor tray body 1 by the anchor nut 3 in conjunction with the rubber gasket 2. The hollow rubber gasket 4 is in close contact with the anchor tray body 1, sealing the contact point between the anchor tray body 1 and the tunnel wall. This tight fit ensures proper contact between the hollow rubber gasket 4 and the anchor tray body 1. Regarding the fit of the contact surface, the buckle 41 is engaged with the limiting slot 12 on the anchor bolt tray body 1. The buckles 41 are circumferentially distributed on the hollow rubber pad 4. By using the circumferentially distributed buckles 41 in conjunction with the limiting slot 12, the hollow rubber pad 4 can be firmly installed on the anchor bolt tray body 1, reducing alignment operations and making the installation of the anchor bolt tray body 1 more convenient and faster. The plug 5 and the center line of the ball head shaft 11 are set to coincide on the axis. By setting the axis of the plug 5 and the ball head shaft 11 to coincide on the axis, the angle between the ball head shaft 11 and the anchor bolt can be the same during installation, and the position of the anchor bolt tray body 1 can also be limited.

[0033] The working principle of this utility model is as follows: When using this device, mortar is injected into the anchor hole, the anchor rod is inserted into the hole, and the anchor hole is sealed with plug 5 after insertion. After the mortar has solidified, the hollow rubber pad 4, the anchor rod tray body 1 and the rubber gasket 2 move from the top of the anchor rod to the tunnel wall. The anchor rod tray body 1 is rotated to drive the ball head shaft 11 to connect with the plug 5. When the anchor rod is in an inclined state, a rubber gasket 2 is installed. After the connection is completed, the anchor rod nut 3 is rotated to apply pressure to the anchor rod tray body 1. During use, the hollow rubber pad 4 seals the contact point between the anchor rod tray body 1 and the tunnel wall, ensuring the airtightness of the contact surface between the anchor rod tray body 1 and the tunnel wall, thereby ensuring the reliability and stability of the anchor rod tray body 1 during use.
