Abstract

The utility model provides a mine car V-shaped propelling rod structure. The mine car V-shaped propelling rod structure comprises a right longitudinal car frame beam and a left longitudinal car frame beam, a medium bridge upper propelling rod bracket, a medium bridge lower propelling rod bracket, a rear bridge upper propelling rod bracket and a rear bridge lower propelling rod bracket are arranged between the right longitudinal car frame beam and the left longitudinal car frame beam, two front upper propelling rods are disposed on the inner side of the medium bridge upper propelling rod bracket, two front lower propelling rods are disposed on the inner side of the medium bridge lower propelling rod bracket, two rear upper propelling rods are mounted on the inner side of the rear bridge upper propelling rod bracket, two rear lower propelling rods are disposed on the inner side of the rear bridge lower propelling rod bracket, the two front upper propelling rods and the two rear upper propelling rods are connected with a propelling rod upper bracket, and the two front lower propelling rods and the two rear lower propelling rods are connected with a balanced suspension. By means of the mine car V-shaped propelling rod structure, the bearing capacity of medium and rear bridges on a poor road surface can be effectively coordinated, and the overload balanced capacity is good.

Description

Mine car V-type propelling rod structure

Technical field

The utility model relates to mine car parts technical field, relates in particular to a kind of mine car V-type propelling rod structure.

Background technology

At present, a lot of manufacturer production Fei highway expanded letter mine cars, upper thrust rod structure mostly adopts single selection structure, while exercising on complex road condition, because of the injustice of jolting on road surface, cause upper thrust rod stressed larger, easily make propelling rod produce fracture, after propelling rod fracture, cause the damage parts such as bridge and transmission shaft, even if increase propelling rod intensity, also cannot eliminate this problem completely.

Utility model content

The purpose of this utility model is to provide a kind of mine car V-type propelling rod structure, the defect that easily produces fracture, causes the damage parts such as bridge and transmission shaft to overcome single pusher structure of prior art.

To achieve these goals, technical solutions of the utility model are:

Mine car V-type propelling rod structure, comprises vehicle frame right vertical beam, the left longeron of vehicle frame;

Between the left longeron of vehicle frame right vertical beam and vehicle frame, be provided with jackshaft upper thrust rod support, jackshaft lower thrust rod support, back axle upper thrust rod support, back axle lower thrust rod support;

Described jackshaft upper thrust rod support inner side arranges two front upper thrust rods, and described jackshaft lower thrust rod support inner side arranges two front lower thrust rods;

Upper thrust rod after the inner side of described back axle upper thrust rod support arranges two, lower thrust rod after described back axle lower thrust rod support inner side arranges two;

After two front upper thrust rods, two, upper thrust rod connects propelling rod upper bracket, and after described two front lower thrust rods, two, lower thrust rod connects balance suspension.

As the improvement to technique scheme, between described two front upper thrust rods, between two front lower thrust rods, after two, the angle between lower thrust rod is 42 ° between upper thrust rod and after two.

As the improvement to technique scheme, described two front upper thrust rods and jackshaft upper thrust rod support, upper thrust rod and back axle upper thrust rod support adopt ball-and-spigot connection structure after two.

As the improvement to technique scheme, described jackshaft upper thrust rod support, back axle upper thrust rod support are integral cast steel part.

Adopted after technique scheme, the beneficial effects of the utility model are:

The utility model propelling rod structure, after two front upper thrust rods, two, upper thrust rod is isometric, there is good interchangeability, and adopt ball-and-spigot connection structure with jackshaft upper thrust rod support, back axle upper thrust rod support respectively, and can 3600 rotations, vehicle is in motion process, propelling rod can move and produce rotation along with all around of bridge, upper and lower all directions, better back axle motion in balance, eliminates various stress, reaches better equilibrium activity.Superpower each four propelling rod structures up and down, in effectively coordinating, back axle, at the load-carrying capacity on severe road surface, has good overload balanced capacity.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
