‌1. Overview

    Coal mine inclined transportation system is an important link that affects the safety production, and the current situation is that some safety guards and protective equipments in inclined transportation are simple, unreliable, without interlocking function, bulky and dangerous to operate. According to the provisions of “Coal Mine Safety Regulations” and “Safety and Quality Standardization”, our company has researched and studied some developed technologies and independently developed the DD-318 type of anti-running car device for different sloping alleys and yards without any industry standards.

2. Main structure

The device mainly consists of pneumatic blocker, pneumatic sleeping gate, pneumatic blocking beam and air control system, and it can choose pneumatic blocker, pneumatic sleeping gate and pneumatic blocking beam for single or multiple combinations, and the air control system realizes the interlocking linkage.

3. Main features 

(1). Pneumatic operation, operation labor-saving, reduce the labor intensity of workers;

(2). It has the function of locking interlocking;

(3). Avoiding the close operation of the hooker, eliminating the personal injury caused by the operation error of the hooker.
