Abstract

The utility model discloses a pneumatic overturning car arrestor, which comprises a base arranged under two guide rails, wherein two stop blocks which respectively correspond to the guide rails are arranged on the base; one end of each stop block is penetratively connected into a pin boss on the base through a circular shaft; a buffering spring is arranged on each circular shaft; a convex block is arranged at the side surface of each stop block; the outer end of each convex block is articulated with a connecting rod through a pin shaft; the other end of the connecting rod is articulated with one end of a rocking arm which is arranged under the base by a rotating shaft; and the other end of the rocking arm is articulated with an air cylinder. The pneumatic overturning car arrestor disclosed by the utility model is applied to a railway transportation line in a coal mine, realizes a car arresting function and is simple in structure, accurate to position, more stably, safe and reliable.

Description

Pneumatic upset stop device
Technical field
The utility model belongs to mechanical field, the stop device on the middle orbit transportation route of a kind of specifically colliery.
Background technology
At present, in the coal mine lower railway transport systems, in vehicular transport and handling process, need to use stop device, the moving ahead of slow and stable prevention vehicle, this is the link of most critical in the transport, deals with the accident that very easily causes vehicle to deviate from track improperly.
The major defect that existing stop device exists has:
1, widely used manual resistance wheel type stop device, driving all needs manual operation up and down.Hinge is many, mechanism is complicated, cost is high, requires also higher to operating environment.In the practical operation, occur the phenomenons of operating against regulations such as the operator leaves office easily, can't realize Long-distance Control.
2, high-end stop device, as infrared detection device test the speed, electromagnetic senser anti-sport car detection, electromagnetic sensing and the detection of time relay speed etc., these stop devices are not that cost height, reliability are low, are exactly the complex structure maintenance difficult, effect is not ideal.
3, simple and easy stop device, like foot-operated stop device, heavy unreliable.The operator if mistake with stop device place ON state or for save muscle power with stone for pressing pedal, be prone to the generation vehicle and deviate from the track accident.
The utility model content
The utility model technical issues that need to address provide a kind of safe and reliable pneumatic upset stop device simple in structure.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of pneumatic upset stop device comprises being arranged on two bases below the guide rail, be provided with above the base two respectively with the cooresponding block of guide rail; One end of said block is through in the key seat of circular shaft cross-under on base; Recoil spring is housed on the circular shaft, and the side of block is provided with a projection, and the outer end of projection is through the hinged pipe link of bearing pin; The said pipe link other end is hinged with an end that is arranged on the rocking arm below the base through rotating shaft, and the other end and the cylinder of rocking arm are hinged.
The centre of two guide rails is provided with the registration device of limit stop turned position above the said base.
Because the technological advance that has adopted technique scheme, the utility model to obtain is:
The utility model is simple in structure, has only three hinge-points, is hinged between rocking arm and cylinder, the pipe link, is hinged between pipe link and the block; The registration device that is provided with, the rotation space of control block, thus make whole device more accurate; On the circular shaft of block, recoil spring has been installed, bumping collision has reduced impact load, and is safer, steady.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1, cylinder, 2, rocking arm, 3, pipe link, 4, block, 5, registration device, 6, recoil spring, 7, base, 8, circular shaft, 9, projection.
The specific embodiment
Below in conjunction with description of drawings the utility model is explained further details:
As shown in the figure, pneumatic upset stop device comprises base 7; Base 7 is a cuboid, and base 7 is fixed by bolts to below two guide rails, also can be welded on base 7 below two guide rails through the mode of welding; On base 7 through the key seat cross-under have two respectively with the cooresponding block 4 of guide rail, an end of block 4 is through in the key seat of circular shaft 8 cross-under on base 7, a projection 9 is welded in the side of block 4; Recoil spring 6 is housed on the circular shaft 8, plays buffer action, the outer end of projection 9 is through the hinged pipe link 3 of bearing pin; Pipe link 3 other ends and rocking arm 2 one ends are hinged, and rocking arm 2 is arranged on through rotating shaft below the base 7, and rocking arm 2 other ends and cylinder 1 are hinged.The centre of base 7 top two guide rails is provided with the registration device 5 of limit stop 4 turned positions.
The principle of work of the utility model is:
Cylinder 1 starts, and cylinder rod stretches out, and promotes rocking arm 2 and rotates around the axis; rocking arm 2 drives pipe link 3 motions; pipe link 3 drives block 4 and outwards rotates, and block 4 retainings are on guide rail, and block 4 is a blocking state; vehicle operating to block 4 places are stopped, slow and stable stopping under the effect of recoil spring 6; When removing blocking state, the withdrawal of the cylinder rod of cylinder 1 drives rocking arm 2, pipe link 3, the motion of block 4 reversing senses, holds up traffic thereby remove.
