Description
Technical field
The utility model relates to a kind of vehicle frame of dumping car vehicular field, particularly a kind of light-duty quarry tipper.
Background technology
Dumping car has heavy-duty tipper, light-duty dumping car is arranged, that uses on the mining area generally is heavy-duty tipper or is called the large-scale mine dumping car is arranged, and this dumping car travels on the road surface, mine, often meet the road surface uneven, one take turns or take turns more and ride height or phenomenon such as sink, vehicle frame is subjected to the effect of fitfull torsional deflection.
Vehicle frame is the core component of car load, and its design and manufacture level are represented car load manufacturer's ability.Quarry tipper is in operational process, and the fracture by fatigue accident often takes place vehicle frame.
At present in the vehicle frame of domestic light-duty rigidity quarry tipper, common have three kinds of structures: first kind of box-shaped vehicle frame for being formed by the high-strength steel plate welding; Second kind is the box-shaped vehicle frame that is formed by punching press or the welding of bending longitudinal and cross beam; The third similar average highway dumping car vehicle frame is riveted the grooved vehicle frame that forms by punching press or bending beam.
By retrieval, we find that open source literature has been reported some mining vehicle carriages in recent years, for example
1. Chinese patent: a kind of novel superduty quarry tipper vehicle frame, application number: 90200741, the applying date: 1990.01.17, publication number: CN2067664, open day: 1990.12.19, applicant: Dalian University of Technology, address: Lingshui River, Dalian, Liaoning province, contriver: Yu Changji; Yu Xuebing; Guo Xinglin; Wang Peizhuan; Sun Yuangui; In all, summary: a kind of novel superduty quarry tipper vehicle frame, a cylindrical beam is equipped with by the upper part in the back partially in the middle of two longerons of box space structure, therefore improves the horizontal torsion stiffness of vehicle frame, improve distribution of stress, prevent fracture, improved service life, economic benefit is very considerable.
2. Chinese patent: a kind of dumping car vehicle frame, application number: 200610160422, the applying date: 2006.11.20, publication number: CN101190663, open day: 2008.06.04, applicant: Chinese International Marine Container (Group) Co., Ltd.; Zhumadian CIMC Huajun Vehicle Co., Ltd., the address: the GangWan Road, SheKou Industrial Zone, Shenzhen City, Guangdong Province No.2 Zhongji Group YanFa Center Building, the contriver: bear is for army building; Hu Zhipeng; Wang Junwei; Zhang Weihua; Yan Baogen, summary: this invention provides a kind of dumping car vehicle frame, comprises the longeron 1 of putting on the shelf, and side is reinforced box 3 to being buckled with a grooved within it, and this reinforcing box 3 is fixed together with the inboard of the longeron 1 of putting on the shelf; Also comprise undercarriage longeron 2, the left and right sides of undercarriage longeron 2 adopts the Z font cross section of looking-glass symmetry, and the inboard of undercarriage longeron 2 reinforces box 4 to being buckled with a grooved, and this reinforcing box 4 is fixed together with the inboard of undercarriage longeron 2; It is fashionable to close at longeron up and down, and a described part of putting longeron 1 on the shelf is embedded in the undercarriage longeron 2.Therefore, this invention has been satisfied the requirement that reduces carrying surface under the situation of anti-bending strength that does not influence vehicle frame and intensity, and it effectively reduces carrying surface greatly about about 60mm, thereby vehicle stability is improved.
3. Chinese patent: quarry tipper vehicle frame, application number: 200820155929, the applying date: 2008.11.25, publication number: CN201309441, open day: 2009.09.16, applicant: Sanyi Science and Technology Co., Ltd., Shanghai, address: No. 319, river, economic garden, Chuansha, Pudong New Area, Shanghai main road, contriver: Cao Zhichun; Zhang Hongru; Zhang Qiang; Zhang Jijian; Li Zhou, summary: this utility model discloses a kind of quarry tipper vehicle frame, comprises collar tie beam, two front side members, two floor side members, safety lever, middle torsion tube, back tailstock.Two front side members are connected in described collar tie beam one side.Two floor side members are connected in the other side of described collar tie beam.Safety lever is arranged at described two front side member front ends.Middle torsion tube is connected between described two floor side members.Back tailstock is arranged at described two floor side member rear portions.Described collar tie beam is distributed on the different vertical cross-section with the bevel for welding of front side member, floor side member.Because collar tie beam is distributed on the different vertical cross-section in the bevel for welding of described front side member, floor side member, therefore, has increased the length of weld seam, improves the stressed distribution of weld seam, has improved the intensity of weld seam, can prolong the service life of vehicle frame.
Through investigation on the spot, all kinds of vehicle frames cut both ways, by gathering the real-world operation fault of various structure frames, find: car load is in operational process, because the road surface, mining area is uneven, vehicle frame bears high-intensity distortion and impact, often cause fracture and torsional deflection, badly influence the safety of vehicle, concerning suspension connected crossbeam and center member, this problem was very outstanding.
In conjunction with actual, need us to design a kind of new frame assembly.
Summary of the invention
The purpose of this utility model provides and a kind ofly can solve fracture and torsional deflection, has simple in structure, a safe and reliable light-duty quarry tipper vehicle frame.
The utility model is achieved in that
Light-duty quarry tipper vehicle frame, comprise a left side, the right vertical beam assembly, preceding support beam assembly, the strength beam assembly, in, rear cross beam assembly, a left side, right balance suspension assembly and suspension tie-beam assembly, with a left side, the right vertical beam assembly is a skeleton, preceding support beam assembly, the strength beam assembly, the center member assembly, suspension tie-beam assembly and rear cross beam assembly are fixed on a left side successively, above the right vertical beam assembly, a left side, right balance suspension assembly is fixed on a left side, aerofoil under the right vertical beam assembly and near on the suspension tie-beam assembly, be characterized in: respectively to indulging that bearing capacity is concentrated, crossbeam, suspension tie-beam parts are strengthened, the inside of longeron assembly is the box type construction composite beam, and the inside of crossbeam assembly and suspension beam is cylindrical, box type construction or the cylindrical and compound composite beam of box-shaped.
Above-described longeron assembly by longeron and interior envelope fine strain of millet mutually the make-up weldering form, be combined into box type construction.
Can adopt various connection modes such as riveted joint, bolted connection, welding to be connected between above-described each crossbeam assembly and the longeron assembly.
Compared with prior art, this novelly has a following advantage:
1. light-duty quarry tipper design-calculated rated load is between average highway dumping car and large-scale mine dumping car, and total mass generally is designed to 40～80 tons, has remedied the blank of China's mine transportation equipment.At complicated condition, the gob that the operation place is narrow has effectively replaced the mining car of average highway dumping car and superduty, comformability is strong, this frame assembly, and longeron assembly and each crossbeam assembly are box type construction, structure is more firm, and structure and technology are simple, intensity is big, long working life.
2. adopt above-mentioned vehicle frame, the inventor has carried out finite element analysis to frame assembly, stress has reduced by 38% after the optimization of suspension tie-beam side plate, the stress of other major parts also decreases, improve the horizontal torsional strength of vehicle frame greatly, improve distribution of stress, prevented fracture and torsional deflection, improve safe reliability.
