Abstract
The utility model discloses a large underground trackless vehicle swing bridge, which comprises an upper swing bridge and a lower swing bridge, wherein two ends of the upper swing bridge and the lower swing bridge are respectively hinged through a joint bearing and a shaft, and a thrust joint bearing is arranged between the upper swing bridge and the lower swing bridge on the shaft of at least one end; both ends of the shaft are supported on the lower swing bridge frame, and the joint bearing is provided with a closed structure. When the road surface is uneven, the vertical swing bridge frame can swing transversely through the shaft and the joint bearing, so that the front and rear drive axles can smoothly contact with the ground, and sufficient traction force is provided; the traction force in the running process of the underground trackless vehicle is transmitted to the upper swing bridge frame from the lower swing bridge frame through the thrust knuckle bearing to reach the vehicle body, and the underground trackless vehicle has the advantages of simple structure, uniform stress and long service life.
Description
Technical field
The utility model relates to a kind of shovel dress and transportation device of mine, particularly relates to a kind of Large Underground free-wheel car and swings crane span structure.
Background technology

In prior art, similar patent family: " swing span " of application number 201020617048.4 and " a kind of Novel swing span of bowl scraper " of application number 201120200552.9 stressing conditions is poor, service life is shorter.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, the Large Underground free-wheel car of uniform force, long service life swings crane span structure.
The purpose of this utility model is achieved through the following technical solutions:
Large Underground free-wheel car of the present utility model swings crane span structure, comprise swing crane span structure and lower swing crane span structure, the two ends of described upper swing crane span structure and lower swing crane span structure respectively by oscillating bearing and axle hinged, and the axle of wherein at least one end swing between crane span structure and lower swing crane span structure on described be provided with thrust articulated bearing;
The car body of described upper swing crane span structure and free-wheel car is fixed, and described lower swing crane span structure rides over above drive axle and drive axle is surrounded, and is connected with drive axle by bolt.
The technical scheme provided as can be seen from above-mentioned the utility model, the Large Underground free-wheel car that the utility model embodiment provides swings crane span structure, when running into Uneven road, swing up and down crane span structure and realize horizontal swing by axle and oscillating bearing, thus make front and back drive axle smoothly and earth surface, enough tractive forces can be provided; Tractive force in underground trackless vehicle driving process is delivered to upper swing crane span structure from lower swing crane span structure by thrust articulated bearing, arrives car body, and structure is simple, uniform force, long service life.

Detailed description of the invention
To be described in further detail the utility model embodiment below.
Large Underground free-wheel car of the present utility model swings crane span structure, its preferably detailed description of the invention be:
Comprise swing crane span structure and lower swing crane span structure, the two ends of described upper swing crane span structure and lower swing crane span structure respectively by oscillating bearing and axle hinged, and the axle of wherein at least one end swing between crane span structure and lower swing crane span structure on described be provided with thrust articulated bearing;
The car body of described upper swing crane span structure and free-wheel car is fixed, and described lower swing crane span structure rides over above drive axle and drive axle is surrounded, and is connected with drive axle by bolt.
The bottom of described lower swing crane span structure is fixed with lower plate, and described lower plate is connected with drive axle by bolt.
The two ends of described axle are all supported on described lower swing crane span structure, and described oscillating bearing is located at the middle part of axle, and described upper swing crane span structure is supported on described oscillating bearing.
Described oscillating bearing is provided with enclosed construction.
Specific embodiment:
As shown in Figures 1 to 5, comprise swing crane span structure 1, lower swing crane span structure 2, these two parts realize being connected by oscillating bearing 6 and axle 5,7.
Realize the principle of underground trackless vehicle teeter:
Upper swing crane span structure 1 welds with the car body of free-wheel car; Lower swing crane span structure 2 and lower plate 3 ride over above drive axle, and drive axle is surrounded, and by being connected with drive axle with bolt.When running into Uneven road, swing up and down crane span structure and realize horizontal swing by axle and oscillating bearing, thus make front and back drive axle smoothly and earth surface, enough tractive forces can be provided.Tractive force in underground trackless vehicle driving process, from lower swing crane span structure by thrust articulated bearing 4, then is delivered to swing crane span structure, arrives car body.
Distinguish the feature that other swings crane span structure:
1, structure stress situation is good.Swing crane span structure in the past, adopt cantilever beam structure to connect upper and lower two swinging structures, namely stressed axle only has one end to be supported, and stressing conditions is bad.One of feature of the present utility model is, the two ends of axle are all supported, and stressing conditions is greatly improved.
2, use the oscillating bearing 6 of band enclosed construction, prevent the muddy water of underground mine from entering Bearing inner and cause bearing damage and life-span to reduce.The service life of structure greatly increases.
3, have employed thrust articulated bearing 4, assume responsibility for axial tractive force.In Large Underground trackless equipment, tractive force is very large, increases thrust articulated bearing, avoids the conical bearing that oscillating bearing or other structure adopt and causes when axial force is excessive the destruction of bearing or life-span to reduce.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
