Abstract
The utility model pertains to the improvement of the backdoor structure of the self-discharging automobile, in particular to a backdoor take-off and landing device for the self-discharging automobile, which comprises a self-discharging automobile carriage and a carriage backdoor connected to the tail of the carriage through the overturning free bearing, wherein the carriage backdoor is symmetrically provided with an arcing arm; the end is respectively hinged with the symmetrical ends of the connection arm and the other end of the symmetric connection arm is respectively hinged with the overturning free bearing symmetrically arranged on the coping of the rear part of the carriage. In the utility model, when the self-discharging automobile overturns backward and unloads, the opened carriage backdoor will not be damaged even scraping on the hard things on the ground, thereby improving the durability. Thus the smooth unloading can be ensured and the unloading is very convenient. The cargo can be unloaded at one time and working efficiency is improved.
Description
Technical field
The utility model belongs to the improvement, particularly dumping truck back door take-off and landing device of door behind the dumping truck.
Background technology
At present, the connection structure of widely used dumping truck back carriage plate device is on compartment board afterbody end face the upset free bearing to be set, and passes through the articulated carriage back door of upset free bearing at the compartment afterbody.When dumping truck was unloaded, hydraulic ram was with compartment jack-up, turned in the compartment, and the bulk freight sliding force backs down carriage back door and unloads.The carriage back door of opening during unloading pushes up ground hard thing sometimes, and as stone or sandstone, the often bad or top distortion with the carriage back door top can't normally be used dumping truck.In addition, this dumping truck back carriage plate device is in when unloading, because bulk freight once can not unload, dumping truck must the limit be unloaded and just opened forward and goods could be unsnatched.
Summary of the invention
The purpose of this utility model is to provide a kind of dumping truck back door take-off and landing device, when carriage of dump truck is turned over unloading, the carriage back door of opening pushes up ground hard thing can not make carriage back door damage yet, increase the service life, can guarantee smooth unloading, and unloading is very convenient, can once unload the clean cargo thing, increases work efficiency.
The purpose of this utility model is achieved in that a kind of dumping truck back door take-off and landing device, comprise carriage of dump truck and be connected the carriage back door of compartment afterbody by the upset free bearing, be symmetrical arranged the dihedral arm on carriage back door top, its end is hinged with the connecting arm end of symmetry respectively, the symmetry its other end of connecting arm respectively with compartment board rear portion end face on symmetrically arranged upset free bearing hinged.
When carriage of dump truck is turned over unloading, when the carriage back door of opening pushes up ground hard thing, carriage back door is subjected to the upwards antagonistic force on top, carriage back door can continue backward upwards upset by the hinge-point of dihedral arm and connecting arm and the hinge-point of the connecting arm other end and upset free bearing, make bigger that carriage back door opens, when having stopped owing to unloading, the carriage back door of opening pushes up on the ground, make the drawback of carriage back door damage or distortion, prolonged the service life at carriage of dump truck back door.Because structure of the present utility model has increased the aperture of carriage back door significantly when making the dumping truck unloading, it is very convenient to unload, and the bulk freight in the compartment is once unloaded only, has improved work efficiency.
