Abstract
The utility model provides a large opening backdoor of a self-dumping car. The utility model is composed of a frame type backdoor, a pull steel cable and a steel cable pull seat, wherein the lower end of the steel cable is connected to the steel cable pull seat, the upper end of the steel cable is connected to the front end of the frame type backdoor, and the frame type backdoor is connected with both sides of a car carriage of the self-dumping car by a pin shaft. The large opening backdoor of a self-dumping car can effectively reduce the damage of backdoors of vehicle, increase the service life of the backdoors of the vehicle, save the maintenance cost of an enterprise and can stop a phenomenon of car carriage turnover during vehicle unloading and an accident during unloading.
Description
Technical field
The utility model relates to a kind of big aperture back door of dumping car, especially a kind of big aperture back door that is used to transport the dumping car of steel scrap and irregular material.
Background technology
Increasing along with national basis Facilities Construction dynamics, the demand of heavy-duty tipper is increasing, about 200,000 of present domestic annual output heavy-duty tippers, but existing self dumping lorory back door jack is generally the hinge type back door, this hinge type back door generally comprises bearing pin, back crossette, supporting seat and back door, crossette is welded on both sides, top, back door after two, on the back crossette pin-and-hole is arranged, two supporting seats are welded on top, biside plate back, compartment respectively, and back, two on back door crossette is connected on the supporting seat in compartment by bearing pin.This dumping car hinge type back door relies on the car door deadweight to open when discharging, and opening angle is little, is about 50 degree, is mainly used in granular materials such as loading and unloading earth, sandstone.Use this self dumping lorory back door jack, discharging vehicle is unloading irregular material such as steel scrap and is hanging easily each other when pulling the material of accumulation, material takes place easily clash into the back door strongly, compartment upset over-education phenomenon, cause vehicle back door gross distortion, if ground, vehicle discharging place injustice, sometimes even the slide-out accident takes place.To the damaged bad problem of vehicle back door and vehicle self, need to strengthen the opening angle at back door when transporting steel scrap and irregular material in order to solve discharging vehicle.
Summary of the invention
The purpose of this utility model is the defective at prior art, has designed the big aperture of the dumping car back door that a kind of opening angle can reach 74 degree.
The utility model provides the big aperture of a kind of dumping car back door, it is characterized in that forming by frame-type back door, tension wire rope and steel rope pulling seat, the steel rope lower end is connected on the steel rope pulling seat by pin I, the steel rope upper end is connected frame-type back door front end by pin II, and the frame-type back door connects by the both sides, compartment of bearing pin with dumping car.
The big aperture of above-mentioned dumping car back door, described frame-type back door is made up of horizontal gird, raker beam and back door, horizontal gird is parallel with the side bar on the compartment and be connected to the both sides of compartment side bar by bearing pin, and becoming captive joint with the back door, raker beam becomes captive joint with horizontal gird with the back door respectively.Wherein the angle between horizontal gird and the back door is 110 degree
Vehicle is close to the compartment at transportation, when filling with substance back door, when the vehicle discharging, the compartment rises under the promotion of elevating ram slowly, at this moment steel rope is just strained the front end of back door frame, force the back door around the S. A. Unscrew, when the compartment arrived the end position of upset, the back door was parallel with the side bar on the compartment, reaches maximum opening angle.
When vehicle lifting reached maximum position, the point of connection at attachment point, steel rope and the frame-type back door of steel rope on the steel rope pulling seat and the hinge-point in back door and compartment can not in-lines, otherwise the excessive easy damage steel rope of pulling force.
The beneficial effects of the utility model:
1. the damage at vehicle back door can be effectively reduced at the big aperture of dumping car back door, has improved the service life at vehicle back door, has saved the maintenance cost of enterprise.
2. the accident that takes place when turning over phenomenon and discharging was crossed in the compartment when vehicle discharging can be stopped in the big aperture of the utility model design-calculated dumping car back door.

Fig. 2 is the constitution diagram of the big aperture of dumping car back door when opening
The specific embodiment
Below with reference to Fig. 1 and Fig. 2 the utility model is described in detail:
The big aperture of the dumping car that the utility model provides back door is made up of frame-type back door 1, tension wire rope 2 and steel rope pulling seat 3, tension wire rope 2 lower ends are connected on the steel rope pulling seat 3 by pin I4, tension wire rope 2 upper ends are connected frame-type back door 1 front end by pin II5, and frame-type back door 1 connects by 7 both sides, compartment of bearing pin 6 with dumping car.
Above-mentioned frame-type back door 1 is made up of horizontal gird 8, raker beam 9 and back door 10, horizontal gird 8 parallel with the side bar on the compartment 7 and be connected to by bearing pin 5 on the both sides side bar in compartment 7 and with the 10 one-tenth captive joints in back door, raker beam 9 respectively with the 10 one-tenth captive joints in horizontal gird 8 and back door.Wherein the angle between horizontal gird 8 and the back door 10 is 110 degree.
Vehicle is close to compartment 7 at transportation, when filling with substance back door 10, when the vehicle discharging, compartment 7 rises under the promotion of elevating ram slowly, at this moment tension wire rope 2 is just strained the front end at frame-type back door 1, force back door 10 around bearing pin 6 Unscrews, when the compartment arrived the end position of upset, back door 10 was parallel with the side bar on the compartment 7, reaches maximum opening angle.When vehicle lifting reaches maximum position, the hinge-point in the point of connection at tension wire rope 23 attachment point, tension wire rope 2 and frame-type back door 1 on the steel rope pulling seat and back door 10 and compartment 7 can not in-line, otherwise the excessive easy damage tension wire rope 2 of pulling force.
