Inclined drift anti-run-off mechanism for mine

Abstract

The invention discloses an inclined drift anti-run-off mechanism for a mine and belongs to the technical field of safety facilities for mines. The mechanism comprises a pulling rope retracting and releasing device, a vehicle retaining column, a rotary encoder and a group of buffer ropes, wherein the pulling rope retracting and releasing device is arranged on the top of a mine roadway; the vehicleretaining column is connected with a wall of the mine roadway; one end of at least one pair of pulling ropes is connected to the vehicle retaining column, and the other end of the pair of pulling ropes is connected with the pulling rope retracting and releasing device; the rotary encoder is arranged on a winch device; the middle of the group of buffer ropes is sleeved on the vehicle retaining column; and one end of the group of buffer ropes is connected with a buffer, and the other end of the group of buffer ropes is connected with another buffer. The mechanism is characterized in that: the pulling rope retracting and releasing device, the winch device and the rotary encoder are in electrical control connection with an electrical control box provided with a programmable logic controller; and the buffer comprises a bottom plate, a group of foundation piles, a group of pressing plates and a protective cover. The invention has the advantages that: a fixing effect between the mechanism and a foundation pit can be improved, and the safety is ensured; and a good action matching effect can be guaranteed, so that the vehicle retaining column rises and falls timely.

Description

technical field [0001] The invention belongs to the technical field of mine safety facilities, and in particular relates to an anti-car mechanism for inclined lanes used in mines. Background technique [0002] In coal mine shafts, metal mines and non-metallic mines, etc., the single-track or double-track lifting and transport inclined lanes with an inclination angle of about 30° or less must be installed in accordance with safety regulations (the first paragraph of Article 370 of the Coal Mine Safety Regulations). The anti-car mechanism is used to prevent the mine car that is in normal traction and moves on the single or double track from running or sliding (called flying car in the industry), that is, the mine car lane is closed by the anti-car mechanism to avoid being caused by sports car and / or slipping. The car caused a major accident. [0003] In the published Chinese patent literature, there have been reports on the anti-sports car mechanism for inclined lanes used in...

Problems solved by technology

[0005] The raised / lowered mechanism of the improved structure of the bumper introduced by CN2685184Y solves the shortcomings of the aforementioned CN201722087U, but does not provide technical inspiration for the fixing of the buffer (the patent is called an energy absorber) and the foundation pit
