Description
Technical field
The utility model relates to a kind of mine car brake equipment, particularly a kind of middle-size and small-size mine car inertia braking device.
Background technology
In order to guarantee the safety of mine car transportation under the mine, the reliable braking of mine car is one of gordian technique, for large-scale segment type mine car, the way that adopts is the pneumatic brake system that equipment evenly disposes in whole train both at home and abroad, to guarantee reliable braking to train, and for needed simple in structure, the reliable operation of middle-size and small-size mine car, brake equipment and control of braking mechanism that cost is low, still blank has directly influenced the safety that a part of mine is produced at present.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of simple in structure, safe and reliable and middle-size and small-size mine car inertia braking device that cost is low is provided.
The technical solution of the utility model is: a kind of middle-size and small-size mine car inertia braking device, it is characterized in that: it comprises that one is arranged on the car body base 9 and the push rod 6 that slides before and after the energy, the two ends of push rod 6 are provided with collision block 7, push rod 6 middle parts are fixedly connected with shifting block 4, be provided with reset attachment 1 near car body base 9 one sides on the push rod 6, fulcrum 8 is arranged on the shifting block 4 below car body bases 9, the upper end of the lever 5 that rotates around fulcrum 8 is arranged on the inboard of shifting block 4, and its lower end is hinged with the brake shoe 3 that is arranged on wheel 2 inboards.
The utility model compared with prior art has the following advantages: the utility model is simple in structure, reliable operation, easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I enlarged drawing of Fig. 1.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, middle-size and small-size mine car inertia braking device comprises a push rod 6 that is arranged on the car body base 9, during brake equipment work, push rod 6 can slide before and after the slideway of being located on the car body base 9, be fixedly connected with shifting block 4 at the middle part of push rod 6, be provided with reset attachment 1 near car body base 9 one sides on the push rod 6, be used to brake resetting of post brake device, collision block 7 is separately positioned on the two ends of push rod 6, fulcrum 8 is arranged on the below car body base 9 of shifting block 4, the upper end of the lever 5 that rotates around fulcrum 8 is arranged on the inboard of shifting block 4, and the lower end of lever 5 is hinged with the brake shoe 3 that is arranged on wheel 2 inboards.
As shown in Figure 2, described reset attachment 1 comprises a spring housing 13, one end of spring housing 13 has the hole, the other end covers on the slideway mouth of the push rod of being located on the car body base 96, and push rod 6 is by passing through perforate in the middle of the spring housing 13, and the spring of being located in the spring housing 13 10 is enclosed within on the push rod 6, the two ends of spring 10 withstand on the baffle plate 12, baffle plate 12 is provided with push rod 6 perforation, and baffle plate 12 is located on the push rod 6 by push rod 6 perforation, and a cylindrical boss 11 is respectively established in the outside of two baffle plates 12.
Middle-size and small-size mine car inertia braking device is arranged on the car body base 9 of mine car, when locomotive brake, be positioned at the locomotive rear portion first segment mine car front portion collision block 7 since inertia bump against with the collision block of being located at the locomotive afterbody, make collision block 7 promote to move after push rod 6 drives the shifting block 4 that is fixed on the push rod 6, the spring 10 of reset attachment 1 is owing to the pushing backward of boss 11 and baffle plate 12 is compressed, the shifting block 4 that moves backward promotes to move behind lever 5 upper ends, lever 5 rotates around fulcrum 8, make the brake shoe that is hinged with it 3 near and compress wheel 2, realize the braking of first segment mine car.Meanwhile, the collision block 7 at first segment mine car rear portion bumps against with second collision block that saves the mine car front portion again, goes down successively, makes each mine car stop mechanism action, realizes the braking of permutation car.After locomotive brake is alleviated, the collision block 7 of each mine car loses pressure gradually, and the spring 10 that is compressed of reset attachment 1 promotes 4 reinstatements of push rod 6 drive shifting blocks forward, and shifting block 4 is left in the upper end of lever 5, the brake shoe 3 of its lower end also just leaves wheel 2, realizes the mine car release of brake.Because mine car bottom brake equipment is except that reset attachment 1, other parts are and are symmetrical arranged, and are not therefore articulated the restriction of direction, and when oppositely articulating, another of mine car is braked wheel.
