Abstract
The invention discloses a frame rear tail base of an electric transmission mining dump vehicle. The fame rear tail base comprises a right tail base casting and a left tail base casting. Matched cylindrical barrels are arranged on the right tail base casting and the left tail base casting respectively. The rear tail base is formed after the right tail base casting and the left tail base casting are connected in a butt joint mode and welded together through butt-joint grooves in the cylinder barrels. Outer side plates in the right tail base casting and the left tail base casting are inserted in the inner sides of longitudinal beams and welded to cushion plates through a joint plate. The cushion plates are arranged on the longitudinal beams through spot welding. By means of the rear tail base structure, the high-stress area is avoided for the welding positions, a frame can bear torsion, bending and impact generated on uneven roads, the integral rigidity, strength and anti-fatigue characteristics of the frame are improved, butt joint weld joints between the left tail base casting and the right tail base casting and between the rear tail base and the longitudinal beams can be easily adjusted, and the installation process is simplified. Holes in the rear tail base and the end faces of the holes can be machined in a rear tail base assembly, and relative positions and precision of the holes and the end faces of the holes are easily ensured.
Description
Technical field
The present invention relates to tailstock structure after a kind of electric transmission carriage of mining self-unloading vehicle, belong to dumper frame technical field.
Background technology
Quarry tipper is the key equipment in surface mine exploitation and extensive earthworks, is the professional equipment for ore or earthwork transportation, have load-carrying greatly, work efficiency high.Current quarry tipper has towards the trend maximized, hugeization develops, also more and more harsher to the requirement of the carrying structure intensity of quarry tipper.The vehicle frame of quarry tipper is as the matrix of car load, the load of other each parts and goods is all applied on vehicle frame, cause vehicle frame to bear the effect of gravity, impact load, torque load and reverse load simultaneously, therefore require that vehicle frame has the characteristics such as good rigidity, intensity and antifatigue.
The vehicle frame of quarry tipper is made up of a pair longeron and multiple crossbeam, and crossbeam forms the enclosed construction of vehicle frame together with longeron.Rear tailstock is exactly wherein one group of crossbeam, be in this vehicle frame afterbody, connect left-right longeron and play the effect of closed whole vehicle frame, its top and the hinged center of gyration as loading space of loading space, bottom and two rear-mounted oil cylinders and an intermediate rod are vertical and be transversely connected to back axle.Not only will support loading space, also the rear-mounted oil cylinder that is forced through of vehicle frame will be passed to back axle, be car load the most complicated stressed parts, because the impact on the reliability of quarry tipper, durability, driving safety of then tailstock is very big.The rear tailstock of current dumper frame is generally formed by steel plate and seamless antitorque steel pipe welding, because welding bead is more, and along with the load carrying ability of current dumping car increasing, in use often occur welding bead cracking phenomenon.
Summary of the invention
For above-mentioned existing technical matters, the invention provides tailstock structure after a kind of super large load carrying ability electric transmission quarry tipper car, larger flexural load, torque load and impact load can be born, the stress reducing stressed concentrated area is concentrated, structural part fractures is avoided to destroy, extend dumper frame service life, meet various functional requirement simultaneously.
The technical solution used in the present invention is:
Tailstock after a kind of electric transmission carriage of mining self-unloading vehicle, is characterized in that, comprises right tailstock foundry goods, left tailstock foundry goods with intermediate rod bore;
Right tailstock foundry goods has with on left tailstock foundry goods the cylindrical tube matched respectively, and right tailstock foundry goods and left tailstock foundry goods are undertaken docking by the butting grooves on cylindrical tube and be welded together to form rear tailstock;
Rear tailstock inserts inside chassis side rail by the outer panel in right tailstock foundry goods and left tailstock foundry goods, welds with the backing plate of spot welding on longeron through a keysets.
Right tailstock foundry goods and one of them individual butting grooves place of left tailstock foundry goods circumferentially arrange the casting backing plate of a circle.
After right tailstock foundry goods and left tailstock foundry goods are welded together to form rear tailstock, on the outer panel of right tailstock foundry goods and left tailstock foundry goods, correspondence offers loading space hinge hole, rear-mounted oil cylinder hinge hole respectively.
Right tailstock foundry goods and the equal casting of left tailstock foundry goods.
Cylindrical tube on right tailstock foundry goods and left tailstock foundry goods and the transition between outer panel are the arc transition of casting.
The auxiliary hole place reserved when the outer panel of right tailstock foundry goods and left tailstock foundry goods is cast arranges cover plate and closes.
The beneficial effect that the present invention reaches:
The cylindrical tube of left tailstock foundry goods 2 and right tailstock foundry goods 1, according to relative position weld together, forms an overall rear tailstock structure; Again the rear tailstock of entirety can be welded on chassis side rail by keysets and backing plate easily afterwards, become a part for vehicle frame; Tailstock structure after this kind, high stress areas is avoided in position of weld, great circle arc transition is used to decrease the sudden change of structure, torsion vehicle frame can being born produce on uneven road surface, bending and impact, improve the integral rigidity of vehicle frame, intensity and fatigue resistance; And location spelling point technique is simple, easily controls welding deformation, and the butt weld easily between the left and right tailstock foundry goods of adjustment and after entirety between tailstock and longeron, greatly simplify mounting process; Loading space hinge hole in rear tailstock, intermediate rod hinge hole, rear-mounted oil cylinder hinge hole and end face thereof can be processed in rear tailstock component, easily ensure relative position and the precision of hole and end face thereof, fine limit work in widgets, handling ease, cycle is short, at the bottom of cost, also easily organizes production.
