Abstract

The utility model relates to the technical field of goods vehicles and discloses a dumper compartment rear door opening and closing device which comprises a swing arm used for connectedly fixing a rear door and hinged on a side plate of a compartment. One end of the swing arm is connected to the lateral side of the rear door while the other end of the same is hinged with a fixed support through a chain, and the fixed support is fixed on an auxiliary frame. Compared with the prior art, the dumper compartment rear door opening and closing device has the advantages that opening angle of the rear door can be twice that of rear doors in common structures, so that material unloading is more convenient and thorough; large-angle material unloading can be realized, so that impact frequency of the rear door is lowered and the rear door is more durable.

Description

The body of tipper carriage opening ﹠ closing device for back door

Technical field

The utility model relates to the load carrying vehicle technical field, especially a kind of device of controlling the railway carriage or compartment door motion of body of tipper carriage.

Background technology

Dumping car is a kind of widely used load carrying vehicle, is usually used in the loading and unloading transport of the earthwork, sandstone, coal, bulk cargo.The compartment of dumping car divides the back to tumbling and two kinds of lateral tilts, and wherein, the back is more general to tumbling, and during the BI dump truck discharge, generally is that lifting device tumbles the compartment compartment lifting backward before utilizing.The back door of existing BI body of tipper carriage afterbody is directly to be articulated on the compartment envelope, and the upper end at back door is articulated in car body top, and when tumbled by lifting in the compartment, open under the effect of deadweight automatically at the back door, to draw off the material in the compartment.But the back door angle that this articulated structure and deadweight mode are opened is limited, when drawing off material, the back door is under little opening angle, be subjected to the bump of material easily, cause the back door to be broken, shortened the service life at back door, and the goods that has drawn off also contacts the back door easily and the back door is deformed, thereby it is cause the carriage back door closure not tight, cause material from leakage, even accidents caused.

The utility model content

The purpose of this utility model provides a kind of body of tipper carriage opening ﹠ closing device for back door, and this carriage back door opening and closing device can solve the problem that the back door is clashed into easily when having body of tipper carriage inclination material now.

In order to address the above problem, the technical solution adopted in the utility model is: this body of tipper carriage opening ﹠ closing device for back door includes be used to the swing arm that is connected and fixed the back door, described swing arm is articulated on the side plate in compartment, one end of described swing arm is connected in the side at described back door, the other end is hinged by chain and fixed bearing, and described fixed bearing is fixed on the subframe.

In the above-mentioned body of tipper carriage opening ﹠ closing device for back door technical scheme, technical scheme can also be more specifically: described swing arm is the triangle swing arm, and an end of described triangle swing arm is connected with described chain, and the two ends in addition of described triangle swing arm are fixed on the described back door.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, the back door can be opened voluntarily by the leverage of chain and swing arm when the compartment lifting;

2, the back door opening angle is big, can reach 2 times of ordinary construction back door opening angle; Can allow the material unloading more convenient, thorough, discharging efficient;

3, the unloading material of wide-angle makes back door bump number of times reduce, and makes it more durable;

4, during the compartment hypsokinesis, rising under the swing arm effect relatively in the back door, has avoided contacting mutually with unloaded bank, prevented from contacting producing distortion.

Description of drawings

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

Fig. 2 is that the A of Fig. 1 is to view.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment:

Body of tipper carriage opening ﹠ closing device for back door shown in Figure 1 mainly includes the triangle swing arm 5 that is articulated on the compartment 4 side plate 4-1, is fixed in the fixed bearing 2 on the subframe 1 and is connected and fixed bearing 2 and the chain 3 of triangle swing arm 5 one ends.Triangle swing arm 5 is used for being connected and fixed

back door

6, and 6 bilateral symmetry is hinged with triangle swing arm 5 at the back door, and side plate 4-1 top, 4 both sides, compartment is symmetrically arranged with hinge 5-1 near the position of envelope rear end, and triangle swing arm 5 is articulated on the side plate 4-1 by hinge 5-1; The two ends of triangle swing arm 5 are connected in the side at back door 6, and the other end is hinged by chain 3 and fixed bearing 2, is connected with brace panel between the arm body of triangle swing arm 5; Fixed bearing 2 symmetries are installed on subframe 1 both sides, and fixed bearing 2 has turning cylinder 2-1, and an end of chain 3 is installed on the turning cylinder 2-1, referring to Fig. 2.

The subframe 1 of dumping car is fixed on the carriage underframe crossbeam, and compartment 4 is located on the subframe 1 and by subframe 1 and is supported, and bottom, 4 rear ends, compartment is hinged with subframe 1 end.Under the situation of finite degrees of freedom, when lifting device drives compartment 4 liftings, envelope rotates around this hinged place, the chain 3 that connects the equal length of both sides triangle swing arm 5 is tensioned on the turning cylinder 2-1 of respective fixation bearing 2, and because chain 3 length immobilize, triangle swing arm 5 is from turning point with hinge 5-1, by lever principle, triangle swing arm 5 drives back door 6 and rotates, and back door 6 is opened, and opening angle is big.
