Description

A mining single pillar fixing device

Technical field:

The utility model relates to a fixing device for a single pillar used in mines, which is suitable for the support, anti-dumping and recovery work of the single pillar under the mine.

Background technique:

As support equipment with small size, reliable support, convenient use and low cost, the single pillar is often used in mines. However, in the case of a large inclination angle or a heavy top beam, the single pillar is easy to topple when it is installed and withdrawn, which poses a great safety hazard. At present, the common single pillar fixing devices have the following disadvantages: (1) the process is complicated and the cost is high, such as the device using a circlip for locking; (3) It affects the normal production of the roadway or the working face, such as adopting chains or bars for interlocking and fixing.

Invention content:

Technical problem: The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a mining single pillar fixing device with simple process, low cost, strong adaptability, and no influence on normal production.

Technical solution: In order to achieve the above purpose, a mining single pillar fixing device of the present invention includes the following components: arc splints (1a, 1b), side connecting plates (3a, 3b, 3c), supporting legs ( 4a, 4b, 4c), pressure plates (5a, 5b, 5c), nuts (6a, 6b) and screws (6c, 6d).

The fixing device for a single pillar for mining is combined in the following manner: one end of the support leg (4a, 4b, 4c) is connected to the pressure bearing plate (5a, 5b, 5c), and the other end is connected to the side connecting plate (3a, 3b, 3c) Connect with the curved splints (1a, 1b), the nuts (6a, 6b) are connected with the screws (6c, 6d) through the screw holes (2a, 2b, 2c, 2d) on the curved splints (1a, 1b).

In the fixing device for single pillars used in mines, the angle between any two supporting legs (4a, 4b, 4c) is between 90° and 150°.

Beneficial effect:

Due to the adoption of the above scheme, the utility model is mainly suitable for the support, anti-dumping and recovery work of the single pillar in the mine. The process is simple, the cost is low, the adaptability is strong, the normal production work is not affected, and the effect is good.
