Abstract
The invention discloses an opening-closing device for a carriage back door of a self-dumper, which relates to the technical field of goods stocks. The opening-closing device comprises a swinging arm for connecting and fixing the back door, wherein the swinging arm is hinged on a side plate of a carriage; one end of the swinging arm is connected to the side edge of the back door, and the other end of the swinging arm 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 opening-closing device has the advantages that the back door opening angle can be twice that of a back door with an ordinary structure, so that materials are unloaded more conveniently and completely; and materials are unloaded at large angles, so that the collision times of the back door are reduced, and the back door is more durable.
Description
Technical field
The present invention 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 backward tumbling and two kinds of lateral tilts, wherein, backwardly tumbles more generally, during the BI dump truck discharge, generally is that lifting device tumbles the compartment carriage 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, easily be subject to the bump of material, cause the back door to be damaged, shortened the service life at back door, and the goods that has drawn off also easily contacts the back door and the back door is deformed, thereby cause the carriage back door closure not tight, cause material from leakage, even accidents caused.
Summary of the invention
The purpose of this invention is to provide a kind of dump truck cabin rear door opening and closing device, the problem that the back door was easily clashed into when this carriage back door opening and closing device can solve existing body of tipper carriage inclination material.
In order to address the above problem, the technical solution used in the present invention is: this dump truck cabin rear door opening and closing device 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 dump truck cabin rear door opening and closing device 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 in addition two ends of described triangle swing arm are fixed on the described back door.
Owing to having adopted technique scheme, the present invention 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 carriage lifting;
2, the back door opening angle is large, can reach 2 times of ordinary construction back door opening angle; Can allow the material unloading more convenient, thorough, discharging efficient;
3, the unloading materials of wide-angle so that back door bump number of times reduces, 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 invention.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing embodiment:
Dump truck cabin rear door opening and closing device 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.In the situation that finite degrees of freedom, when lifting device drives compartment 4 lifting, 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 corresponding fixed bearing 2, and because chain 3 length immobilize, triangle swing arm 5 is take hinge 5-1 as from turning point, by lever principle, triangle swing arm 5 drives back door 6 and rotates, and back door 6 is opened, and opening angle is large.
Claims (2)
1. dump truck cabin rear door opening and closing device, it is characterized in that: include 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.
2. dump truck cabin rear door opening and closing device according to claim 1, it is characterized in that: described swing arm is the triangle swing arm, and an end of described triangle swing arm is connected with described chain, and the in addition two ends of described triangle swing arm are fixed on the described back door.
