The lower ends of vertical girders are separately articulated with both ends of the beam while the upper ends are articulated with the upper part of the two side box board back and lock pins are disposed at the position corresponding to the automatic locking device at the back end of the body frame. The model removes the original standing posts of the dumper bucket, therefore, the structure is simple, use is convenient and cost is reduced, moreover, the model realizes flat dumping in the true sense.

Description

The self lighting type wagon box

Technical field

The utility model is particularly related to a kind of self lighting type wagon box.

Background technology

Existing self lighting type wagon box is by under-carriage, is welded on the column of both sides, under-carriage rear end respectively, constitutes with column upper end pivotally attached grooved framework and boxboard, and described boxboard is divided into two side box plates and forward and backward boxboard.Wherein, two side box plate lower ends are hinged by folding and under-carriage, and rearing-box plate lower end and grooved framework are hinged.This self lighting type wagon box is when opening two side box plates and rearing-box plate and carry out handling goods, because column is fixed on the under-carriage and can not moves, so just brought great inconvenience to handling goods, especially all the more so when the width of loading thing surpasses the under-carriage width.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of self lighting type wagon box of simple in structure, easy to use, low cost of manufacture is provided.

The utility model is achieved in that it comprises under-carriage, grooved framework and boxboard, described boxboard be by two side box plates and before, rearing-box plate constitutes, the grooved framework is by crossbeam and the upright beam that is located at the crossbeam two ends respectively constitutes, two side box plate lower ends are hinged by folding and under-carriage, rearing-box plate lower end and crossbeam are hinged, upper end, rearing-box plate both sides is connected by latching device with upright beam, between under-carriage and crossbeam, be provided with the automatic lock hook device, its special character is: described Li Liang lower end is hinged with the crossbeam two ends respectively, upright beam upper end is hinged with two side box plate rear upper end respectively, and corresponding automatic lock hook device place is provided with lock pin in the under-carriage rear end.

The utility model has the advantages that: because the Li Liang lower end is with crossbeam is hinged, upright beam upper end and two side box plates are hinged, make this self lighting type wagon box cancel the column of original self-unloading wagon box, simple in structure, really realized dull and stereotyped self-unloading, extremely easy to use, and reduced manufacturing cost.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right elevation of Fig. 1;

Fig. 3 is the birds-eye view of Fig. 2.

Among the figure: 1-under-carriage, 2-boxboard, boxboard before the 201-side box plate, 202-, 203-rearing-box plate, 3-automatic lock hook device, 301-latch hook, 302-limit skateboard, 303-pull bar, the 4-folding, 5-Connection Block, 6-lock pin, 7-folding, 8-grooved framework, the 801-crossbeam, 802-founds beam, the 9-latching device, the 901-driving lever, 902-locating bush, 903-hook, 10-connecting panel, the 11-free bearing, 12-bearing pin, 13-oil cylinder free bearing, 14-base plate.

The specific embodiment:

As shown in the figure, the utility model has a under-carriage 1, is covered with base plate 14 on under-carriage 1, is provided with boxboard 2 on under-carriage 1, described boxboard 2 is to be made of two side box plates 201 and preceding boxboard 202, rearing-box plate 203, and two side box plate 201 lower ends are hinged by folding 4 and under-carriage 1.Be welded with free bearing 11 respectively two side box plate 201 rear upper end, on two free bearings 11, be hinged with connecting panel 10 by bearing pin 12 respectively, be connected with grooved framework 8 two connecting panel 10 lower ends, described grooved framework 8 is to be made of crossbeam 801 and the upright beam 802 that is located at crossbeam 801 two ends respectively, upright beam 802 is hinged on the crossbeam 801 by folding 7, and described connecting panel 10 correspondences are welded on two upright beam 802 upper ends.Described rearing-box plate 203 lower ends and crossbeam 801 are hinged by folding 4, between under-carriage 1 and crossbeam 801, be provided with automatic lock hook device 3, described automatic lock hook device 3 be by the latch hook 301 that is hinged on bottom surface, under-carriage 1 rear portion and be hinged on under-carriage 1 anterior bottom surface limit skateboard 302 and with latch hook 301 and limit skateboard 302 respectively pivotally attached pull bar 303 constitute.Corresponding latch hook 301 places are provided with lock pin 6 in under-carriage 1 rear end, be connected by latching device 9 respectively between upper end and the preceding boxboard 202 between described rearing-box plate 203 both sides upper ends and the upright beam 802, before two side box plates 201, described latching device 9 is by locating bush 902, is inserted into the interior driving lever 901 of locating bush 902 and links up with 903 and constitute.Be welded with Connection Block 5 in bottom surface, under-carriage 1 rear portion, be welded with oil cylinder free bearing 13 in under-carriage 1 anterior bottom surface.

During use, it is hinged with the car body base that this self lighting type wagon box is passed through Connection Block 5, and the cylinder rod end of overturning oil cylinder is hinged on the oil cylinder free bearing 13.During handling goods, can open rearing-box plate 203 or two side box plates 201 or rearing-box plate 203 and side box plate 201 according to actual needs separately and all open, thereby realize that real dull and stereotyped entrucking and flat board unload.When the dull and stereotyped self-unloading of needs, promote lock pin 6 in advance automatic lock hook device 3 is pinned, open rearing-box plate 203 then successively and two side box plates 201 get final product.
