Anti-running method for gradient tunnel track transportation

Abstract

The invention discloses an anti-running method for gradient tunnel track transportation, which belongs to the technical field of gradient mine shaft or tunnel track transportation, particularly relates to the technical field of gradient mine shaft or tunnel track transportation safety, and solves the technical problem that a gradient tunnel for track transportation brakes in time at the moment of broken rope running start to prevent the occurrence of running accidents and avoid the occurrence of body injury accidents. The invention adopts the technical scheme that the method comprises the following steps of: 1, increasing a hook head vehicle between a track transportation train and a steel wire rope, and arranging a slack-rope automatic closing device on the hook head vehicle; 2, arranging a braking track on a track center line of the gradient shaft or tunnel; 3, discontinuously arranging rope erecting wheels on the braking track center line; and 4, operating the slack-rope automatic closing device on the braking track section of the track along the braking track so that the slack-rope automatic closing device is clasped and braked with the braking track when the rope is broken and loosened with the braking track when the rope is not broken; and operating the slack-rope automatic closing device on the non-braking track section of the track so that the slack-rope automatic closing device is completely separated from the braking track. According to the method, when the steel wire rope is broken, the braking device is closed in time and performs braking, and the braking device is in a working state all the time when the transportation vehicle is transferred.

Description

technical field [0001] The invention discloses a sports car-proof method for inclined shaft and roadway rail transportation, which belongs to the technical field of mine inclined shaft or roadway rail transportation, and particularly relates to the technical field of mine inclined shaft or roadway rail transportation safety technology. Background technique [0002] According to the relevant provisions of Article 370 of the "Coal Mine Safety Regulations", the composition and installation of the sports car protection system for inclined lanes follow the following principles: (1) Install a car arrester near the slope change point in the upper parking lot; (2) Install about one train at the slope change point (3) Install the sports car protection device step by step in the inclined roadway according to the actual working conditions of the roadway transportation (roadway length, slope, quality of stringing cars, distribution of partial openings, etc.). [0003] In the inclined la...

AI Technical Summary

Problems solved by technology

[0005] The above two anti-car devices represent the current mainstream of anti-car devices in inclined shafts or roadways. The disadvantages of this kind of anti-car device and this kind of similar anti-car device are: 1. The mine car does not take anti-car device at the moment when the broken rope sports car is started. Sports car measures; 2. When intercepting vehicles, the closed flexible interception structure is subjected to the impact force of the transport vehicle after acceleration; 3. The reliability of the closed flexible interception structure cannot be guaranteed due to the complex conditions of the mine environment
