Abstract
The utility model discloses a double-support swing rack of an underground scraper. A front support plate and a rear support plate are connected via an upper fixing plate. A front protective plate and a front shaft sleeve are disposed at the outer side of the front support plate. A rear protective plate is disposed at the outer side of the rear support plate, and a rear shaft sleeve is disposed at the inner side of the rear support plate. The axial center of the front shaft sleeve and the axial center of the rear shaft sleeve are located on the same axis. The utility model also discloses a rear vehicle frame of the underground scraper. A bridge plate is connected with a front upper support plate, a rear support rack and a bridge-plate reinforcing plate. A scraper body is connected with the bridge plate, the front upper support plate and the rear support rack.

The utility model further discloses an underground scraper. The underground double-support swing rack is connected with the underground scraper via the rear vehicle frame of the underground scraper. The forced situation of the swing rack is changed, and instead of a cantilever beam, front and rear support points are forced, thereby solving the problem of high failure rate of underground scrapers due to the single-support design of swing racks and prolonging the service lifetime of the underground scraper, the double-support swing rack and the rear vehicle frame.
Description
Technical field
The utility model relates to a kind of down-hole haulage device and assembly thereof, is specifically related to car frame behind a kind of underground scraper, a kind of underground scraper double base swing span and a kind of underground scraper.
Background technology
The working environment of underground scraper and condition of work very severe adapt to the situation of stope Uneven road in order to make underground scraper, increase the stability of machine in dress ore deposit or transport, all are designed with the swing mechanism that is called swing span.Swing span is assurance front truck after-frame is made relative swing in certain angle a mechanism.Swing span is arranged on the back axle, is called the back axle swing span.The characteristics of this swing span are: the back vehicle frame is hinged through the gyroaxis device and the swing span of swing span; And make between back vehicle frame and the back axle and guarantee to have enough swing spaces; Make machine when uneven road surface passes through; Back axle is through swing span afer bay swing relatively, and afer bay still can keep the normal position when back axle is swung.
When scraper shoveled ore deposit or transportation on smooth road surface, because four wheels land simultaneously, at this moment swing span was not worked.When scraper shovels ore deposit or transportation on broken terrain; The back axle revolver lands, and right wheel soars, and revolver is faced its active force at this moment with receiving and extended on the swing span; Add that the back vehicle frame acts on action of gravity on the back axle on swing span; Make swing span produce a moment, this moment makes swing span rotate around the swing span gyroaxis, and the right wheel of drive back axle lands.The right wheel of same back axle lands, and when revolver soars, also can land through swing span back axle revolver, so can keep forward and backward bridge wheel to land all the time through the back axle swing span.Therefore, the underground scraper of swing span has been arranged, when on the road surface of injustice, going, the both sides wheel can guarantee kiss the earth simultaneously, improves the condition of adhering to of wheel, makes full use of the weight of sticking together of complete machine, the insertion force of increasing traction and scraper bowl.
Because the working space of down-hole is less, existing scraper is a single support structure for utilization of space generally adopts the swing span design of rear driving axle, and this project organization is simple; Easy to process; But also there are some defectives in single supporting rocker, mainly contains the following aspects: (1) is installed in the back vertically in the hole, discontinuity because the swing gyroaxis of back axle swing span is cantilever ground; Be prone to cause gyroaxis wearing and tearing or bearing premature failure, cause swing span to damage.(2) same owing to cantilever, swing span seems that insufficient strength, hold-down nut are prone to become flexible, and are prone to fracture during use.(3) the swing span manufacturability is bad, and internal stress and distortion that welding causes make that machining accuracy is difficult for guaranteeing.
