Abstract
The utility model relates to a gravity stopper device and install device's coupling buffer, its characterized in that: gravity stopper device includes a bedplate, at an one end rotation connection backset of bedplate, the dog that extends outside the integrative setting earlier on in the backset. Coupling buffer is including installing the gravity stopper device on coupling buffer's hook shadoof seat. The utility model discloses owing to rotate with the one end of one side at bedplate installation hook shadoof seat and connect a backset, consequently the integrative outer dog that extends earlier on that sets up is overturning when unloading in the backset, and the backset remains perpendicular state downwards throughout under self action of gravity, can stop through the dog during in advance to the removal of round hole department when the hook shadoof, prevents that the spring bolt from unblanking voluntarily. The utility model discloses simple to operate, simple structure, do not influence normal coupling buffer's use, improved the fail safe nature of vehicle upset discharge operation simultaneously.
Description
Technical field
The utility model relates to a kind of gravity lock catch device and is provided with the coupler and draft gear of this device, belongs to railway transport field.
Background technology
Tipper is a kind of large-scale, efficient mechanization unloading equipment, is used for the loose unpacked materials such as the coal of dumping different kinds of railways open-top car delivery, ore and grain.Along with the fast development of railway truck heavy haul transport, railway truck rate of discharging requires more and more higher, and tipper is because efficiency is high, cost is low and can Automated condtrol, and therefore tipper unloading system becomes the important tool of unloading.Along with the requirement of market to tipper unloading system is more and more higher, occurred double-car dump, 3-car dumper, four car dumps etc. that efficiency is higher, this kind of tipper can not understood train of vehicles and is carried out upset unloading operation.When train of vehicles separated by needs, as shown in Figure 1, only the hook shadoof 201 of coupler and draft gear 200 upwards need be lifted, it is made to move to circular hole place from the square hole of the handle hole 203 of hook uncoupling rod bracket 202, and at circular hole place, hook shadoof 201 is rotated 90 °, hook tongue 204 can be opened thus realize separating train of vehicles.Although train of vehicles can not understood during many car dump work carries out unloading operation, but in vehicle turnover process, hook shadoof 201 can slide into circular hole place from the square hole of handle hole 203 under gravity, dead bolt 204 is opened automatically cause vehicle to unblank the generation of accident.
In order to avoid the generation of above-mentioned situation, existing most heavy-duty freight car adopts No. 17 hitches, and No. 17 hitches itself have good anti-jump performance, and its anti-jump backing block causes the auto-unlocking of dead bolt after can preventing locking iron play during overturning operation.Simultaneously anti-jump latch can control the rotation of hitch lock pin composition, and then causes dead bolt after avoiding hook lock moves.But because heavy-duty vehicle operation road conditions are severe, longitudinal direction of car collides frequent, and cause the problem such as Train hamulus severe wear and the distortion of anti-jump latch, loss to occur, these faults all can cause the automatic unlatching of dead bolt.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of structure gravity lock catch device simple and easy for installation and is provided with the coupler and draft gear of this device.
For achieving the above object, the utility model takes following technical scheme: a kind of gravity lock catch device, is characterized in that: it comprises a seat board, is rotationally connected a backset in one end of described seat board, and described backset is wholely set an outward extending block.
The gap being greater than 2mm is left between described seat board and described backset.
Described seat board offers multiple through hole.
The diameter of described through hole is 17mm.
A kind of coupler and draft gear, is characterized in that: it comprises the described gravity lock catch device be arranged on the hook uncoupling rod bracket of described coupler and draft gear.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model is owing to being rotationally connected a backset in one end of seat board hold-down hook uncoupling rod bracket the same side, backset is wholely set an outward extending block, therefore when carrying out upset unloading, backset remains state vertically downward under self gravitation effect, can be stopped by block when hook shadoof moves to circular hole place in advance, prevent dead bolt auto-unlocking.2, the use that the utility model is easy for installation, structure simply, does not affect normal coupler and draft gear, improves the safe reliability of vehicle turnover unloading operation simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing coupler and draft gear;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises one for the seat board 1 of hold-down hook uncoupling rod bracket 202, be rotationally connected a backset 2 in one end of seat board 1 hold-down hook uncoupling rod bracket 202 the same side, backset 2 is wholely set an outward extending block 3, and block 3 is for limiting the shift position of hook shadoof 201.
In above-described embodiment, between seat board 1 and backset 2, leave the gap being greater than 2mm.
In above-described embodiment, seat board 1 offers multiple through hole 4 for hold-down hook uncoupling rod bracket 202.The diameter of through hole 4 is 17mm.
The hook uncoupling rod bracket 202 of coupler and draft gear 200 in use, as shown in Figure 1, is first fastenedly connected with seat board 1, then by the handle hole 203 of hook shadoof 201 through hook uncoupling rod bracket 202 by the utility model.When tipper carries out upset unloading operation, hook shadoof 201 can overturn together along with tipper, and hook shadoof 201 can be moved to circular hole place by the square hole of handle hole 203 under gravity simultaneously.Now, because seat board 1 and hook uncoupling rod bracket 202 are fastenedly connected, and backset 2 and seat board 1 are rotationally connected, no matter therefore backset 2 is followed hook shadoof 201 and is turned to any position and all can remains state vertically downward under self gravitation effect, hook shadoof 201 is stopped by block 3 in advance when circular hole place moves, make hook shadoof 201 can not move to the automatic unlock deadbolt 204 in circular hole place, ensure that in whole upset operation process, hook tongue 204 is in locking states, guarantee upset vehicle and cargo security.
Above-mentioned each example is only for illustration of the utility model; wherein the structure of each parts, connection mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
