Abstract
The utility model relates to a back tail seat for a dumper frame, and belongs to the field of dumpers. The utility model aims to provide a back tail seat for a dumper frame, which is cast by high strength alloy, has a few weld passes and can realize various functions. A left back tail seat, a cylinder, and a right back tail seat are welded together to form an integral back tail seat structure; and front ends of the left and right back tail seats have rectangular sections, and are welded with a longitudinal beam of the frame together to form one part of the frame. Six round holes are symmetrically processed on the left and right back tail seats correspondingly to realize functions of hinging a carriage, inserting a safety pin and mounting a rear suspension cylinder. In addition, the cylinder has a thick-wall large-diameter circular tube structure, and is welded with the left and right back tail seats which are made in high strength together, and the strength and the rigidity are high, so that the integral torsion resistance of the frame is improved.
Description
Technical field
The utility model relates to tailstock behind a kind of dumping car vehicle frame, belongs to the dumping car field.
Background technology
Tailstock is used for hinged compartment and vehicle frame behind the dumping car vehicle frame, can rotate and the function of discharging around vehicle frame to realize the compartment.The back tailstock of general dumping car vehicle frame is formed by the steel plate welding, because welding bead is more, and along with the load carrying ability of present dumping car is increasing, the phenomenon of welding bead cracking often takes place in use.The function singleness of back tailstock can only realize the function that the compartment rotates around vehicle frame in addition.
Summary of the invention
The purpose of the utility model is to provide a kind of can prolong tailstock behind the vehicle frame dumping car vehicle frame in service life.
Technical solution:
The utility model comprises left back tailstock, right back tailstock, between left back tailstock and right back tailstock, is provided with cylindrical shell, and the left back tailstock and the right back tailstock outside are respectively equipped with compartment hinge hole, safety pin jack, rear overhang cylinder hinge hole.
The utility model is at left back tailstock, cylindrical shell, right back tailstock weld together; Form a back tailstock structure on the whole; Can bear vehicle frame and on uneven road surface, adopt living tersional stress, improve the whole torsional property of vehicle frame, in use have reliability height, long characteristics of life-span.
Description of drawings
Fig. 1 is the front view of the utility model structure;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
The utility model is provided with cylindrical shell 2 between left back tailstock 1 and right back tailstock 3; Left back tailstock 1, cylindrical shell 2, right back tailstock 3 weld togethers; Form a back tailstock structure on the whole; The front end of left back tailstock 1 and right back tailstock 3 is square-sections, with the longeron weld together of vehicle frame, becomes the part of vehicle frame.Because the high stress areas of back tailstock has been avoided in the position of weld of cylindrical shell 2 and left and right back tailstock 3, make the back tailstock in use have reliability height, long characteristics of life-span.The left back tailstock 1 and right back tailstock 3 outsides are respectively equipped with compartment hinge hole 4, safety pin jack 5, rear overhang cylinder hinge hole 6.The utility model forms a back tailstock structure on the whole at left back tailstock 1, cylindrical shell 2, right back tailstock 3 weld togethers,
The compartment hinge hole is used for realizing the function of hinged compartment and vehicle frame.
The utility model also processes an equirotal circular hole in the corresponding position with the corresponding compartment of safety pin jack; When at maintenance and maintenance vehicle; The compartment lifting is put in place; This moment, the circular hole on the compartment overlapped with circular hole on the tailstock of back, and safety pin is inserted in the circular hole, can realize preventing the compartment because hydraulic system fails and the possibility that falls suddenly.
Rear overhang cylinder in rear overhang cylinder hinge hole and the rear-suspension system is hinged through bearing pin and oscillating bearing, because the back tailstock adopts the high-strength alloy manufacturing, can bear very big stress, makes that like this installation of rear suspension is simple and reliable.
Cylindrical shell adopts the thick-wall and large-diameter circular tube structure in addition, and with the left and right back tailstock weld together that high strength is made, the strength and stiffness of self are very big, can bear vehicle frame and on uneven road surface, adopt living tersional stress, improved the whole torsional property of vehicle frame.
