Description
Technical field
The present invention relates to a kind of can large-scale engineering machinery voluntarily or the chassis of heavy military equipment, the machinery such as the most large-scale rotary drilling rig or goliath, or the chassis of heavy weight missile haulage vehicle.
Background technology
Along with the requirement of domestic and international infrastructure construction, the demand of large-scale engineering machinery increases day by day, such as, strengthen the demand of large-scale rotary drilling rig the most further.But existing large-scale engineering machinery all uses two crawler belts contact ground runnings, also exist that complete machine structure is big, complete machine structure center of gravity is high, and the deficiency of the poor stability of complete machine in construction operation.As a example by rotary drilling rig, with high ferro, the construction of road and bridge and sea land wind-powered electricity generation cause makes the demand of rotary drilling rig day by day increase, during but existing rotary drilling rig manufactures, chassis all uses two crawler belt contact ground runnings, the construction requirement strengthening along with stake footpath, deepening, domestic each main engine plants mostly use increase chassis structure size and crawler width mode to meet requirement when design, and drawback all occurs in the machinery manufactured by aforesaid way.Being mainly manifested in some large-scale rotary drilling rigs, owing to output moment of torsion is bigger, cause complete machine structure increase, weight to increase, complete machine structure center of gravity raises, and in construction operation, the stability of complete machine is poor；It is relevant that the stability of structure and structure contact formed supporting surface size with ground, supporting surface is the biggest more stable, and supporting surface is the least more unstable, and existing rotary drilling rig only has two crawler belt contact ground, the supporting surface that its structure and ground base are formed is less, therefore the stability of structure is not enough；It addition, large-scale rotary drilling rig mostly uses the creeper tread that 1m is wide, comparing with the creeper tread of narrower width, 1m broad track plate is easier to unstability in the direction of the width.The most existing large-scale engineering machinery and heavy military equipment there is also the deficiency that walking is poor with climbing capacity.How to solve the problems referred to above, be key subjects in engineering equipment manufacture field.
For solving the deficiency that prior art exists, the Chinese invention patent of Patent No. 201510929021.6 is disclosed a kind of one side and by two frame track frame parallel connections welding or is assembled by attachment means, four crawler crane track beams, chassis and the crawler crane of the parallel track beam of composition.Although this patent can preferably solve the deficiency that prior art exists, but due to two crawler belts of its erection outrigger so that it is the big increase of width of equipment, so at equipment conveying, or can be limited by road conditions when equipment transition.The most this equipment is when special operation occasion works, during as worked in operation area, soft earth's surface, although this equipment stability in operation is better than prior art, but determines owing to it supports moment, it is possible to there is stable not enough problem.
Summary of the invention
The present invention provide a kind of overcome prior art not enough be available for can the chassis that uses of large-scale engineering machinery voluntarily or military equipment.
A kind of chassis of the large-scale engineering machinery of the present invention, including: what vehicle frame and vehicle frame were fixedly connected is respectively used to arrange two track beams of crawler belt, and the crawler belt on track beam is set, the two ends of each track beam have the parts being provided for installing crawler belt respectively, the track beam of the present invention is the hollow box beam that its cross section is rectangular, the guide rail that can match it is provided with external track frame outer surface in track beam, and for positioning the device of fixing external track frame；Chassis is additionally provided with the external track frame that can be inserted into track beam, described external track frame is similarly one section of rectangular hollow box beam of cross section, it is respectively arranged with, in track beam and outside external track frame casing, the guide rail matched, track beam and external track frame is also respectively provided with both and is mutually located fixing device.Due to the present invention is by existing track beam end insert install an external track frame, so can not only realize equally arranging four crawler belts identical with 201510929021.6 Chinese invention patents on chassis, the job stabilization of raising equipment, and owing to two crawler belts of peripheral hardware can be dismantled by removing external track frame, therefore limited in place or transport can remove two crawler belts of peripheral hardware, thus can reduce the width of equipment, be allowed to meet transport or the requirement in place.Separately it should be noted that in case of need, the present invention can also arrange guide rail in the case of external track frame again, it is inserted into second " external track frame " wherein, Article 3 crawler belt can be set at the homonymy of equipment with this, corresponding engineering machinery is made to have six crawler belts the most a plurality of, so be possible not only to be greatly improved engineering machinery stability, significantly can reduce the pressure to ground by equipment so that it is be more suitable for the different areas of activity in soft geology condition and use simultaneously.
The chassis of the large-scale engineering machinery of the present invention is respectively respectively equipped with at least one pin hole matched with alignment pin on external track frame and insertion track beam, is made up of described pin hole and alignment pin and is mutually located fixing device between track beam and external track frame.Its structure of this device for positioning and securing of the present invention is extremely simple, but its fixed effect is very reliable, and its dismounting operation also extremely convenient.
In one embodiment on the chassis of the large-scale engineering machinery of the present invention, in the track beam casing with external track frame, it is provided with dismountable extension oil cylinder, track beam can be made to produce displacement with external track frame position along its length by the effect of extension oil cylinder.External track frame can be adjusted after the present invention arranges extension oil cylinder more conveniently and insert the position of track beam.
Preferably, the chassis of the large-scale engineering machinery of the present invention can arrange least one set reinforcement in the casing of external track frame, to strengthen the rigidity of external track frame.
The invention have the advantage that
1) assembly and disassembly of crawler belt can be carried out easily so that it is may be adapted to the requirement of transport and various Active workings；
2) position of expansible peripheral hardware crawler belt and quantity so that it is be more suitable for the different areas of activity of different geological conditions, can reduce the grounding pressure of equipment simultaneously, and then make the stability of complete machine improve；
3) extension that can realize external track frame position by extending oil cylinder is moved, and the crawler belt handling making peripheral hardware are extremely easy, and the adjustment of position is the simplest and the most direct；
4) track beam and external track frame all use bin girder construction, can reduce the weight of equipment, also can save the cost of manufacture simultaneously；
5) by arranging reinforcement in external track frame, not only increase the rigidity of external track frame, its weight can be alleviated again simultaneously；
6) four, the most a plurality of crawler belt can be used due to the present invention, therefore can be selected for reductor common on market, its overall size is less, and then makes the center of gravity of design chassis structure reduce, this both can improve the stability of complete machine, can reduce cost and the difficulty of manufacture simultaneously；
7) when using four crawler belts, the engineering machinery that the present invention is combined into can use four type of drive, makes heavy construction equipment be provided with superior walking and climbing capacity.
