Protecting device with dust falling function for coal mining

Abstract

The invention discloses a protecting device with a dust falling function for coal mining. The protecting device comprises inserting rods, a supporting plate, an anti-collapse net and a safety rod, a base is arranged above the inserting rods, bearing blocks are arranged at the top of supporting rods, and a beam column is fixedly connected with the bearing blocks through fastening bolts; and connecting cylinders are arranged in the middles of first support rods and the middles of a second support rods correspondingly, clamping hooks are arranged on the inner sides of the right ends of the supporting rods, limiting columns are arranged on the lower portions of the left ends of the clamping hooks, the safety rod is connected to the lower portion of a connecting rod, and a transverse rod is arranged in the top end of the connecting rod. According to the protecting device with the dust falling function for coal mining, a supporting frame makes contact with the top of a mine conveniently, sothat the supporting frame supports the mine conveniently, ventilation and dust falling are facilitated, the environment safety inside the mine is guaranteed, the place outside a support is protected conveniently, anti-collapse early warning is arranged, and the safety of workers is guaranteed conveniently.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a protective device for coal mining with the function of reducing dust. Background technique [0002] With the rapid development of the national economy, the demand for coal mines in the market is also increasing. Coal mining is to mine underground or open-pit coal for people to use. In the process of mine coal mining, in order to avoid mine tunnel collapse , It is necessary to support and protect the shaft of the coal mine. [0003] The current protective devices used in coal mine development are mostly only a support frame during use. There is a gap between the support frame and the top of the mine, which cannot fully support the stability of the mine, and it is inconvenient to settle the dust in the mine, and it is inconvenient It is inconvenient to set collapse warning for the protection of places other than the support frame. Therefore, we propose a protective device fo...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of protective device for coal mine exploitation with dust-reducing function, to solve the current protective device for coal mine exploitation proposed by the above-mentioned background technology, in the process of use, mostly only a support frame is set, and the support frame is connected with the mine shaft. There is a gap at the top of the mine, which cannot fully support the stability of the mine, and it is inconvenient to settle the dust in the mine, and it is inconvenient to protect the place other than the support frame, and it is inconvenient to set the collapse warning.
