Description

Wagon backdoor latching device

Technical field

The utility model relates to waste-skip box technology field, specifically a kind of wagon backdoor latching device.

Background technology

Waste-skip at present as Special dumpcart has played increasing effect in the waste transportation of town and country, for improving waste transportation amount and transport efficacy, the railway carriage of waste-skip also more and more maximizes, the quantity of refuse that railway carriage loads also gets more and more, the locking of the wagon backdoor therefore maximized also seems important all the more, lock not in place, insecure, rubbish will be caused to spill in transport process, cause rubbish secondary pollution, for this reason current Dumpcart wagon backdoor is all provided with various latching device to strengthen locking property, but due to existing latching device normally a locking piece use a hydraulic actuating cylinder to drive, adopt during more latching device and will seem that structure is mixed and disorderly, take up room large, equipment investment cost increases.

Utility model content

Technical problem to be solved in the utility model is: provide that a kind of structure is simple, take up room the wagon backdoor latching device little, input cost is low.

The technical scheme that the utility model adopts is: provide a kind of wagon backdoor latching device, be located at railway carriage respectively on the two side at back door, comprise hydraulic actuating cylinder, first latch hook, second latch hook and connecting rod, described first latch hook and the second latch hook are located on body side wall up and down, the middle part of the first latch hook and the middle part of the second latch hook are all rotatably connected on body side wall by bearing pin, the gib head of the first latch hook and the second latch hook all hooks the locking pin on back door, described hydraulic actuating cylinder is located between the first latch hook and the second latch hook, the cylinder body of hydraulic actuating cylinder is hinged on body side wall, the push rod of hydraulic actuating cylinder and the hook tail end of the second latch hook hinged, one end of described connecting rod and the hook tail of the first latch hook hinged, the other end is connected to the junction of the second latch hook and body side wall by a plate.

After adopting above structure, the utility model wagon backdoor latching device two latch hook device arrange a hydraulic actuating cylinder, and by the connection of connecting rod, hydraulic actuating cylinder can the opening and closing of the company's of driving latch hook simultaneously, reach that structure is simple, equipment is few, the advantage that input cost is few; Hydraulic actuating cylinder push rod is not directly connected with connecting rod, is driven by rotating pin, and hydraulic actuating cylinder can not be stressed excessive; Hydraulic actuating cylinder is arranged between the first latch hook and the second latch hook, designs ingenious, has the advantage occupied little space.

As preferably, second latch hook of railway carriage both sides and the pinned connection of railway carriage junction integral, the rotating pin of both sides second latch hook links into an integrated entity, the power of both sides hydraulic actuating cylinder can be made full use of, strengthen the coupling mechanism force of latch hook, reduce the power suffered by single Driven by Hydraulic Cylinder two latch hooks, extend hydraulic actuating cylinder service life.

In figure, 1, railway carriage, 2, back door, 3, connecting rod, 4, hydraulic actuating cylinder, 5, connecting panel, the 6, second latch hook, the 7, first latch hook, 8, locking pin.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in detail.

As shown in FIG. 1 to 3, the utility model wagon backdoor latching device, railway carriage 1 arranges two groups, be located at railway carriage 1 respectively on the two side at back door 2, comprise hydraulic actuating cylinder 4, first latch hook 7, second latch hook 6 and connecting rod 3, first latch hook 7 and the second latch hook about 6 are located on the sidewall of railway carriage 1, the middle part of the first latch hook 7 and the middle part of the second latch hook 6 are all rotatably connected on railway carriage 1 sidewall by bearing pin, the gib head of the first latch hook 7 and the second latch hook 6 all hooks the locking pin 8 on back door 2, namely the hook tail of the first latch hook 7 and the second latch hook 6 is in railway carriage 1 side, gib head extends to back door 2, the locking pin 8 that gib head hooks on back door 2 realizes locking, or throw off the unlatching that locking pin 8 realizes back door 2, hydraulic actuating cylinder 4 is located between the first latch hook 7 and the second latch hook 6, the cylinder body of hydraulic actuating cylinder 4 is hinged on railway carriage 1 sidewall, the push rod of hydraulic actuating cylinder 4 and the hook tail end of the second latch hook 6 hinged, one end of connecting rod 3 and the hook tail of the first latch hook 7 hinged, the other end is connected to the junction of the second latch hook 6 and railway carriage 1 sidewall by a plate 5.

The utility model in the specific implementation, hydraulic actuating cylinder 4 and the second latch hook 6 are located between connecting rod 3 and railway carriage 1, second latch hook 6 and railway carriage 1 are rotated on railway carriage 1 by bearing pin, concrete structure can be that connecting panel 5 and the second latch hook 6 are welded on bearing pin, and bearing pin rotates relative to railway carriage 1, also can be that bearing pin is fixed on railway carriage 1, bearing pin overcoat upper bush, sleeve rotates relative to bearing pin, and connecting panel 5 and the second latch hook 6 are welded on sleeve, connecting panel 5 other end and connecting rod 3 hinged.

Second latch hook 6 of railway carriage 1 both sides of the present utility model and the pinned connection of railway carriage 1 junction integral, the bearing pin that namely the second latch hook 6 is connected with railway carriage 1 crosses railway carriage 1 Width, and the bearing pin of both sides second latch hook 6 and railway carriage 1 is linked to be one.

The utility model is not limited to above version; latch hook can adopt three, four,,; each Driven by Hydraulic Cylinder two latch hooks or three latch hooks; railway carriage homonymy can arrange two groups of said structures; only otherwise depart from substance design of the present utility model, all at protection domain of the present utility model.
