Description
Technical field
The utility model belongs to scraper technical field, relates in particular to a kind of swing span and the ground including the swing span
Lower scraper.
Background technology
Working environment and condition of work all very severes of underground carry scraper, in order to improve by performance, using front and rear car
Body articulation steering structure and front-rear axle four-wheel drive, in order that four-wheel can contact ground simultaneously, have been generally designed and have referred to as put
The swing mechanism of moving frame, swing span can make opposing oscillatory around car body longitudinal axis in certain angle, to improve wheel
Attachment condition, make full use of the insertion force of the weight of sticking together of complete machine, increasing traction and scraper bowl.In order that working device of underground scraper
Part keeps preferable stability, and swing span is generally located in aftercarriage, i.e. car body where engine.
For large-scale scraper, using bridge lower space come mounting arrangements swing span, upper space can be saved, is made
Top fluid torque-converter and the hydraulic oil pump and fluid pressure line installed thereon can be arranged in the top of swing span, can so make
Scraper structure characteristics of compact layout, vehicle length of wagon is reduced, reduce vehicle radius of turn, improved vehicle and pass through performance.Due to bridge
Lower space is smaller, and the structure design to swing span brings difficulty, meanwhile, existing swing span is embedded in vehicle frame by axle
In mounting hole, and vehicle frame mounting hole is semicircular subdivision structure, and difficulty of processing is big.
Utility model content
For a variety of deficiencies of prior art, in order to solve the above problems, it is proposed that a kind of swing span and including the swing
The underground scraper of frame.
To achieve the above object, the utility model provides following technical scheme：
A kind of swing span, including support body is swung, the forward and backward both ends for swinging support body are respectively equipped with connection component, described
Connection component includes taper roll bearing and bearing pin, and one end of the bearing pin is free end, and its other end is sheathed on taper roller
In bearing inner race, the taper roll bearing is positioned at the end for swinging support body, positioned at the bearing pin and swing span for swinging support body front end
Body is fixedly connected.
Further, it is provided with first flange between the taper roll bearing and swing support body.
Further, it is connected positioned at the bearing pin for swinging support body front end with swinging support body by second flange.
In addition, the utility model also provides a kind of underground scraper, including above-mentioned swing span and vehicle frame.
Further, the vehicle frame is provided with the mounting hole of full-round structure, the free end insertion mounting hole of the bearing pin
It is interior, and bearing pin is fixedly connected with vehicle frame.
Further, the bearing pin is bolted with vehicle frame.
The beneficial effects of the utility model are：
Bearing pin and vehicle frame are attached by bolt, ensure that relative motion is not present between the mounting hole of bearing pin and vehicle frame,
Avoid wearing, meanwhile, mounting hole is full-round structure, and compared with existing subdivision structure, intensity is big, sturdy and durable,
Mounting hole processed complex, easily damaged is solve thed problems, such as, effectively reduces processing cost, improve vehicle frame uses the longevity
Life, in addition, in swing span installation process, it is only necessary to bearing pin is embedded in mounting hole and fixed again with bolt, improves swing span
Installation and the convenience changed.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
In accompanying drawing：1- swings support body, 2- taper roll bearings, 3- bearing pins, 4- taper roll bearings, 5- bearing pins, 6- first
Flange, 7- second flanges, 8- bolts, 9- vehicle frames.
Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, with reference to of the present utility model
Accompanying drawing, clear, complete description is carried out to the technical solution of the utility model, it is general based on the embodiment in the application, this area
