Bidirectional hook type braking car

Abstract

The invention discloses a bidirectional hook type braking car. The bidirectional hook type braking car comprises two hook type braking devices and a braking rail. Each hook type braking device comprises a pull rod which is connected with a front mine car and a rear mine car. The other end of each pull rod penetrates through a guide sleeve. A compressed spring I is connected to the inner side of each guide sleeve. Each pull rod is sleeved with the corresponding compressed spring I. The end of each pull rod is connected with a guide plate through a nut. The other end of each compressed spring I is in contact with the corresponding guide plate and drives the guide plate to slide inside the corresponding guide sleeve. Each hook type braking device further comprises a connecting rod and a braking rod. Each pull rod is hinged to the corresponding connecting rod through a hinge pin I. Each connecting rod is hinged to the corresponding braking rod through a hinge pin II. A braking sleeve on each braking rod is engaged with tooth grooves in the braking rail. Each braking rod is hinged to an axle. The braking car is provided with a reversing device so that reversed braking can be achieved. The compressed springs are arranged on the braking rods so that braking force can act on the braking car in a buffered mode. By means of the braking devices of the braking car, fast braking can be achieved, no power source needs to be arranged additionally, manufacturing cost is low, installation is easy, and maintenance is convenient.

Description

technical field [0001] The invention relates to a braking mine car, in particular to a two-way hook type braking car. Background technique [0002] Inclined mine car rail transportation is a mode of transportation widely used in mines such as coal mines. Phenomena such as pinning and causing the problem of mine car or mine car train train, cause safety production casualty accident to often take place. [0003] The commonly used anti-sports car device has following several forms at present, and a kind of is to detect the running speed of mine car by sensor in mine, in case finding stall situation utilizes car net or car bar to block mine car. The disadvantages of this method are: the weight of the intercepting device is heavy, it is inconvenient to install, carry and maintain on site, and it is difficult to popularize and use; the intercepting device can only be used once, which not only wastes materials, but also destroys the continuity of mine production. strenuous [00...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: the weight of the intercepting device is heavy, and it is inconvenient to install, carry and maintain on site, and it is difficult to popularize it; the intercepting device can only be used once, which not only wastes materials, but also destroys the continuity of mine production. strenuous

The disadvantages of this method are: equipment debugging and maintenance procedures are complex and complicated, the electronic products used in the equipment have poor dust resistance and corrosion resistance, and the performance of electronic products is unstable after long-term use, and sometimes they will fail at critical moments. Failure or misoperation; What's more, an inclined shaft needs multiple interceptions to achieve a better effect, which not only increases the cost of the mine, but also fails to achieve 100% interception effect
