Horizontal inclined shaft rail safe car arresting system

Abstract

The invention discloses a horizontal inclined shaft rail safe car arresting system, which is arranged on a horizontal inclined shaft rail. The horizontal inclined shaft rail is formed by two parallel iron rails; the safe car arresting system comprises two-way reversible car arresters, an automatic safety door and a control device; the two-way reversible car arresters are arranged at the two sides of the iron rails; the automatic safety door is arranged on a variable slope point of the horizontal inclined shaft rail; the control device is connected with the two-way reversible car arresters and the automatic safety door. The horizontal inclined shaft rail safe car arresting system has the advantages that the automatic safety door device is added, so that the rail car arresting protection is more perfect; a mechanical car arresting mode is adopted; a mine car is subjected to two-way controllable car arresting; the horizontal inclined shaft rail safe car arresting system can adapt to the frequent and variable mine car transportation flow process; the symmetrical spring structural design is used, so that the impact damage is effectively reduced; the stable car arresting is realized; the service life of equipment is prolonged; the safety and the stability are improved.

Description

technical field [0001] The invention relates to the technical field of mine vehicle operation equipment, in particular to a safety vehicle stop system for horizontal inclined shaft tracks. Background technique [0002] The horizontal inclined shaft track of coal mines is generally divided into a down line and a weight car line. The down line is used to group the empty mine cars into the inclined shaft. In the process of operation and marshalling, in order to prevent single or multiple mine cars from running out of control, hub clamping deceleration devices and car arresters are generally installed on the rails. The existing mine car arresters are generally self-propelled car arresters. The device has a pair of claws, which are used to stop the meeting of the mine car or the shaft of the mine car. The car stopper is provided with a rotating shaft. In the natural state, it is in an upward state, and a limit block is set in the rotation area at the bottom of the claw. When the...

Problems solved by technology

[0003] The self-propelled car stopper can only stop cars in one direction, and cannot adapt to the frequent and changeable mine car transportation process, and the car stop process is a hard collision, which causes great damage to the equipment and is not conducive to long-term use and maintenance

[0004] In addition, the slope-changing point between the horizontal section of the horizontal inclined shaft track and the inclined shaft section of the coal mine is a frequent point of safety accidents, and a safety guard bar is installed on the slope-changing point as a monitoring point for mine car transportation. Simple blocking effect, this safety protection mode has certain hidden dangers, especially the safety guard bar is relatively fragile, if the front-end car stopper or deceleration device fails, it is difficult to block the mine car, especially the heavy-duty mine car, causing security incident
