Problems solved by technology

Due to the different mine conditions and roadway conditions, many mines have not installed "inclined lane sports car protection device" due to various factors. Reasons, most of them cannot be in effective working condition
Most of the existing protection devices for sports cars in inclined lanes are uniformly installed with a traffic barrier on the track. The car was seriously damaged
At the same time, the existing protective device for the inclined road sports car does not measure the payload of the mine car in the early stage of the mine car entering the inclined road, which will cause the overweight mine car to enter the track, which is prone to accidents

Embodiment Construction

[0010] like figure 1 As shown, the automatic safety protection device for mine inclined lane track has a winch 2 for providing power to the mine car 4 and a speed detection device 3 for detecting the speed of the winch. At the upper end and the bottom of the inclined alleyway, a car arrester 5 is installed, and the car arrester at the upper end of the inclined alley is a normally closed state, and the car arrester at the lower end of the inclined alleyway is a normally open state. A plurality of anti-vehicle grids 6 are evenly installed on the inclined lane; the said anti-vehicle grid 6 is composed of a grid frame 61 installed on the inclined roadway, a gate 62 installed on the grid frame and a power mechanism for opening and closing the gate 62 63; the gate 62 adopts a gate with an arc-shaped surface; when an accident occurs, the gate 62 can provide a buffer for the mine car 4 and reduce damage to the mine car. The power mechanism adopts a winch, and the motor of the winch i...

Abstract

The invention discloses a safety automatic protection system of a mining inclined roadway track, relating to the technical field of mining roadway safety protection. In the invention, the device comprises a speed detector; car arresters are arranged at the upper end and the lower end of an inclined roadway; a plurality of car arresting grids are uniformly arranged on the inclined roadway track; the car arresting grids comprise grid frames arranged on the roadway, circular-arc gates arranged on the grid frames and power mechanisms for opening / closing the gates; a proximity switch and a safety switch are arranged on each car arresting grid; PLC (Programmable Logic Controller) control boxes are respectively arranged on platforms at the upper end and the lower end of the inclined roadway and are respectively electrically connected with a motor of a winch, the speed detector, the car arresters, the power mechanisms and the safety switches; and weighing devices are arranged at platforms at the upper end and the lower end of the track and are electrically connected with the PLC control boxes. The device provided by the invention has the advantages of high reliability, strong practicability, good safety performance and overall comprehensive protection; and the system has stronger anti-interference ability and can adapt to complex and variable environments of a mine.

Description

technical field [0001] The invention relates to the technical field of safety protection of mine roadways, in particular to an automatic protection system for inclined mine roadways, which is suitable for rail transportation of inclined shaft roadways in mines and other places. Background technique [0002] In the mine system of our country, many mines use inclined shafts to lift. Due to the different mine conditions and roadway conditions, many mines have not installed "inclined lane sports car protection device" due to various factors. Most of the reasons are not in effective working condition. Most of the existing protection devices for sports cars in inclined lanes are uniformly installed with a traffic barrier on the track. The car was severely damaged. At the same time, the existing protective device for the inclined road sports car does not measure the payload of the mine car when the mine car enters the inclined road, which will cause the overweight mine car to en...
