Abstract
The utility model discloses a self-locking car arrester, including the connecting plate, the bottom both sides of connecting plate respectively are provided with an ear seat, rotate between two ear seats and are connected with the round pin axle, and the both ends of round pin axle are located the position between two ear seats and all radially are connected with the supporting leg, and the lateral wall center of round pin axle is provided with the stop gear who fixes to the connecting plate bottom. The self-locking car arrester of the utility model can support the rear end of the supporting leg to the ground when the train goes up a slope and backs, thereby assisting the braking and playing the role of preventing the falling of the track; when the train normally goes up a slope, the train moves forwards along with the train, which is equivalent to installing a train arrester moving along with the train at the train.
Description
Technical Field
The utility model belongs to the technical field of coal mining track equipment, concretely relates to auto-lock car arrester.
Background
The derailment of the coal mining equipment train is a serious accident, and one reason is that the train arrester fails. However, when a train is pulled, the train stopper cannot move forwards at any time along with the forward movement of the train, only the front and rear steel wire ropes fix the train, and once the train falls off when going up a slope and going back, the train cannot be braked in time, so that an accident occurs.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a auto-lock car arrester can assist the braking when the train goes up the slope and reverses.
The utility model adopts the technical proposal that: the self-locking car arrester comprises a connecting plate, wherein two sides of the bottom of the connecting plate are respectively provided with an ear seat, a pin shaft is rotatably connected between the two ear seats, the two ends of the pin shaft are positioned between the two ear seats and are both radially connected with supporting legs, and the center of the side wall of the pin shaft is provided with a limiting mechanism fixed to the bottom of the connecting plate.
The utility model is also characterized in that,
the limiting mechanism comprises a limiting groove arranged at the center of the side wall of the pin shaft, a clamping ring is sleeved in the limiting groove, and a connecting rod is fixed between the outer side of the clamping ring and the bottom of the connecting plate.
The connecting plate is provided with a connecting hole.
The supporting leg is rectangular shape, and the supporting leg keeps away from the one end bottom of round pin axle and contracts for the slope shape to the direction of round pin axle.
A compression spring is sleeved on the pin shaft between the supporting leg and the ear seat close to the supporting leg.
The utility model has the advantages that: the self-locking car arrester of the utility model can support the rear end of the supporting leg to the ground when the train goes up a slope and backs, thereby assisting the braking and playing the role of preventing the falling of the track; when the train normally goes up a slope, the train moves forwards along with the train, which is equivalent to installing a train arrester moving along with the train at the train.
Drawings
FIG. 1 is a schematic structural view of the self-locking car arrester of the present invention;
fig. 2 is a left side view of the self-locking car arrester of the present invention in fig. 1.
In the figure, 1, a connecting plate, 2, an ear seat, 3, a pin shaft, 4, a supporting leg, 5, a limiting groove, 6, a clamping ring, 7, a connecting rod, 8, a connecting hole and 9, a compression spring.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a from locking car arrester, as shown in figure 1 and figure 2, including connecting plate 1, connecting hole 8 has been seted up on connecting plate 1, the bottom both sides of connecting plate 1 respectively are provided with an ear seat 2, it is connected with round pin axle 3 to rotate between two ear seats 2, the position that the both ends of round pin axle 3 are located between two ear seats 2 all has supporting leg 4 along radially being connected with, the cover is equipped with compression spring 9 on round pin axle 3 between supporting leg 4 and the ear seat 2 that is close to, supporting leg 4 is rectangular shape, the one end bottom that round pin axle 3 was kept away from to supporting leg 4 is to the direction shrink of round pin axle 3 for slope shape, the lateral wall center of round pin axle 3 is provided with the stop gear who fixes to 1 bottom of connecting plate.
Stop gear is including offering the spacing groove 5 at 3 lateral wall centers of round pin axle, and the snap ring 6 has been registrated in the spacing groove 5, is fixed with connecting rod 7 between the outside of snap ring 6 and the connecting plate 1 bottom to it is fixed to have guaranteed that round pin axle 3 and connecting plate 1 and ear seat 2 relative position.
During operation, place connecting plate 1 in train bottom platform and be connected with it through connecting hole 8, later with two supporting legs 4 separately to 2 directions of ear seat that are close to and extrusion compression spring 9 respectively for two supporting legs 4 stabilize the block in the orbital both sides of train. When the train normally goes up a slope, because the two supporting legs 4 are movably connected with the ear seats 2 and the pin shafts 3, the two supporting legs 4 can move forwards along with the train and do not form resistance to the train; when the train goes up the slope and reverses, the bottom of two supporting legs 4 supports ground and constitutes the support to connecting plate 1 and then to the train, even two supporting legs 4 are uneven because of the difference of track both sides ground height and atress, also can not cause round pin axle 3 to deviate from ear seat 2 because stop gear's effect.
Through the mode, the self-locking car arrester of the utility model has the advantages that the rear ends of the supporting legs 4 can be abutted to the ground when a train goes up a slope and backs, so that the auxiliary braking can play a role in preventing the train from falling; when the train normally goes up a slope, the train moves forwards along with the train, which is equivalent to installing a train arrester moving along with the train at the train.
