Abstract
The utility model relates to a heavy mining self-unloading vehicle, especially a heavy mining self-unloading vehicle frame, which is characterized in that: a lower cross beam is disposed on the lower end surface of a casting; an upper cross beam is disposed on the upper end surface of a casting; the top board of the rear longitudinal beam is a horizontal board; the bottom board is an inclined board; and the integral body is a box girder with variable cross-section. The utility model has a reasonable and unique structure, which can bear greater shocking load, bending load and twisting load; reduce the stress concentration on stress concentrated position, avoid fracture of longitudinal beam, and improve the using performance of mining self-unloading vehicle.
Description
One, technical field
The utility model relates to a kind of mining heavy mining truck, particularly heavy mining truck vehicle frame.
Two, background technology
The actual environment for use of heavy mining truck is more abominable, and vehicle frame bears the effect of gravity, impact load, torque load and reverse load simultaneously.The vehicle frame of the heavy mining truck of Xiao Shouing is to set crossbeam in the foundry goods lower surface in the market, forms semiclosed circle type beam.Back longitudinal beam structure is whole be inclined upwardly certain angle or straight uniform cross section box beam.So easily cause stress concentration position welding bead cracking and longeron fracture damage.
Three, summary of the invention
The purpose of this utility model is to provide a kind of can bear bigger impact load, flexural load and torque load, reduces the stress concentration at stressed concentrated position, avoids the longeron rupture failure, improves the heavy mining truck vehicle frame of quarry tipper in-use performance.
Technical scheme: the foundry goods lower surface is provided with cross sill, and the foundry goods upper surface is provided with entablatrance, and the floor side member upper plate is a horizontal plate, and lower shoe is the hang plate with angle of inclination, and integral body is the variable cross-section box type beam.
Entablatrance, foundry goods and cross sill form totally-enclosed circle type beam.
The lower shoe of floor side member and the angle of inclination of horizontal surface are 1 °-2 °.
The utility model floor side member adopts the welding box-shaped girder construction of high strength steel variable section, and box type structure girder can well bear flexural load and torque load.The longeron upper plate is designed to horizontal structure, and lower shoe is designed to incline structure, makes longeron integral body be variable section structure, and this has solved the restriction because of the compartment shape, loads center of gravity near vehicle frame the place ahead, causes chassis side rail discontinuity problem.Can make vehicle frame whole stressed evenly reasonable, avoid the longeron fracture damage.Reaching under the situation of bearing load simultaneously, and can loss of weight.Cross member of frame is designed to totally-enclosed circle type structure, and the entablatrance and the cross sill of circle type beam are designed to welding box-shaped structure, has solved when using under harsh environment because of vehicle, it is serious to jolt, the vibrations of vehicle frame both sides are inconsistent, and crossbeam bears bigger torsional moment, the problem of stress concentration.
The utility model reasonable in design, uniqueness, this structure can be born bigger impact load, flexural load and torque load, reduces the stress concentration at stressed concentrated position, avoids the longeron rupture failure, improves the quarry tipper in-use performance.
Four, description of drawings
Fig. 1 is the utility model configuration diagram;
Fig. 2 is the structural representation of the utility model crossbeam.
Five, the specific embodiment
The utility model comprises crossbeam 1, floor side member 2, back tailstock 3, front side member 4, bumper/spoiler 5, foundry goods 8, and the upper surface of foundry goods 8 is provided with entablatrance 6, and the lower surface of foundry goods 8 is provided with cross sill 7, entablatrance 6, foundry goods 8 and the totally-enclosed circle type beam of cross sill 7 common formation.Floor side member 2 upper plates are horizontal plate, and lower shoe is a hang plate, and the angle of inclination of hang plate and horizontal surface is 1 °-2 °, and floor side member integral body is the variable cross-section box type beam.
The utility model is in car load, the compartment is above after cross member 2, because of close crossbeam 1 direction of the main loading station in compartment, the impact load of bearing apart from nearly near more floor side member 2 positions of crossbeam 1 when load at the place is greater than floor side member 2 positions away from crossbeam 1, floor side member 2 can produce downward flexure deformation under the effect of gravity simultaneously, produce bigger moment of flexure, in this case, floor side member 2 is designed to the upper plate level, lower shoe bevelled variable cross-section box type girder construction, horizontal upper surface can evenly be born gravity loading, make the floor side member 2 and the weld of crossbeam 1 and back tailstock 3 can not produce bigger stress concentration, the bevelled lower surface is used for bearing more and more littler gravity loading, the force request that had so both guaranteed floor side member 2 has the complete vehicle weight that alleviates, box-structure can bear bigger torque load and flexural load, makes floor side member 2 that rupture failure not take place.In the process of vehicle operating, because actual road conditions are relatively jolted, in the process of jolting, can make left and right sides two parts of vehicle frame produce the trend that divides to both sides, just can bear complicated torque load at crossbeam 1 position, having bigger tensile stress simultaneously concentrates, crossbeam 1 is designed to fully enclosed circle type structure, entablatrance 6 and cross sill 7 are welded together with foundry goods 8, the destruction that the pulling force to both sides that can avoid producing because of jolting brings, entablatrance 6 and cross sill 7 are welding box-shaped structure simultaneously, and this structure can be born torque load, and foundry goods 8 is the great circle arc foundry goods, this has just been avoided concentrating of stress, has reduced the cracking of welding bead.
