Abstract
The utility model discloses a mine car buffer which comprises a collision head seat, a rubber collision head, springs and positioning pin shafts. The mine car buffer is characterized in that the collision head seat is a steel casting of which three sides are closed and one side is open, wherein the steel casting is provided with a cavity, and a boss with two positioning springs is formed in the cavity of the steel casting; the collision head seat is provided with two small through holes; after the rubber collision head and the springs are arranged in the cavity, the positioning pin shafts are inserted from the small through holes to fix the rubber collision head; and the collision head seat is provided with a big through hole for the insertion of a mine car connecting pin shaft and the connection of one mine car and other mine cars or the connection of one mine car and other equipment. The mine car buffer has the advantages of reasonable structure, low cost, convenience in installation and use, safety and reliability; and when the mine cars collide with each other and stop, the mine cars are buffered through the buffer, and collision spark is not produced, so that the mine cars can be popularized and applied to coal powder and gas roadways.
Description
Technical field
The utility model relates to the fields such as colliery, tunnel piercing, specifically a kind of mine car buffer.
Background technology
In many engineering fields such as coal mining and tunnel piercing, the track transportation is very extensive, in the track transportation, generally uses the mine car transportation.Because itself does not have brake system mine car, the junction between mine car and the mine car all was to be welded with rigidity to meet and discuss in the past, realized that hard collision connects.This kind connects that not only vibratility is large, and easily produces spark, is difficult for using in coal dust and gas tunnel are arranged, and limited general the enclosing of use of mine car.The utility model has solved the problem of above-mentioned existence.
Summary of the invention
The technical problems to be solved in the utility model is: design a kind of mine car buffer, mine car is collided when stopping mutually, obtain buffering, do not produce the collision spark, mine car can be applied to having in coal dust and the gas tunnel.
The technical solution of the utility model:
A kind of mine car buffer comprises the seat of meeting and discussing, rubber meets and discusses, spring, alignment pin, and it is characterized in that: the described seat of meeting and discussing is that three side sealing closes, an opening, with the steel part foundry goods of cavity, in its cavity with the boss of two retainer springes; The seat of meeting and discussing is provided with two small through hole, the rubber of packing in the cavity meet and discuss and spring after, enter to insert alignment pin from small through hole, it is fixing that rubber is met and discussed; The seat of meeting and discussing is provided with a large through-hole, and this through hole inserts mine car and connects bearing pin and uses, and is used for being connected of mine car and mine car or mine car and miscellaneous equipment.
Described a kind of mine car buffer is characterized in that: the described rubber outer end of meeting and discussing is an arc surface, and there are boss and two C shape pawls that positioning rubber is met and discussed of two retainer springes the inner.
Effect of the present utility model: rational in infrastructure, with low cost, installation, easy to use, safe and reliable is collided when stopping mine car mutually, obtains buffering, does not produce the collision spark, and mine car can be applied to having in coal dust and the gas tunnel.

The specific embodiment
Referring to accompanying drawing, a kind of mine car buffer of device described in the utility model, comprise that the seat 1 of meeting and discussing, rubber meet and discuss 2, spring 3, alignment pin 4, it is characterized in that: the described seat 1 of meeting and discussing is that three side sealing closes, an opening, with the steel part foundry goods of cavity, the interior boss with two retainer springes 3 of its cavity; The seat of meeting and discussing 1 is provided with two small through hole, the rubber of packing in the cavity meet and discuss 2 and spring 3 after, enter to insert alignment pin 4 from small through hole, it is 2 fixing that rubber is met and discussed; The seat of meeting and discussing 1 is provided with a large through-hole, and this through hole inserts mine car and connects bearing pin and uses, and is used for being connected of mine car and mine car or mine car and miscellaneous equipment.
Claims (2)
1. mine car buffer comprises that the seat of meeting and discussing, rubber are met and discussed, spring, alignment pin, and it is characterized in that: the described seat of meeting and discussing is that three side sealing closes, an opening, with the steel part foundry goods of cavity, in its cavity with the boss of two retainer springes; The seat of meeting and discussing is provided with two small through hole, the rubber of packing in the cavity meet and discuss and spring after, enter to insert alignment pin from small through hole, it is fixing that rubber is met and discussed; The seat of meeting and discussing is provided with a large through-hole, and this through hole inserts mine car and connects bearing pin and uses, and is used for being connected of mine car and mine car or mine car and miscellaneous equipment.
