Description
Technical field
This utility model relate to a kind of can large-scale engineering machinery voluntarily or the chassis of heavy military equipment, the most large-scale rotation
Dig the machinery such as 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 to large-scale
The demand of rotary drilling rig strengthens the most further.But existing large-scale engineering machinery all uses two crawler belt contact ground runnings, deposits
, complete machine structure center of gravity height big at complete machine structure, and the deficiency of the poor stability of complete machine in construction operation.With rotary drilling rig it is
Example, makes the demand of rotary drilling rig day by day increase with the construction of high ferro, road and bridge and sea land wind-powered electricity generation cause, but existing
Rotary drilling rig manufacture, chassis all uses two crawler belts 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, aforesaid way institute when design
All there is drawback in the machinery manufactured.It is mainly manifested in some large-scale rotary drilling rigs, owing to output moment of torsion is bigger, causes complete machine to be tied
Structure increases, weight increases, and complete machine structure center of gravity raises, and in construction operation, the stability of complete machine is poor；The stability of structure
Contacting formed supporting surface size with ground with structure relevant, 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, and the supporting surface that its structure and ground base are formed is less, therefore structure
Stability not enough；It addition, large-scale rotary drilling rig mostly uses the creeper tread that 1m is wide, compare with the creeper tread of narrower width,
On width, 1m broad track plate is easier to unstability.The most existing large-scale engineering machinery and heavy military equipment there is also row
Walk the deficiency 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 discloses one
Planting one side by two frame track frame parallel connections welding or to be assembled by attachment means, four crawler belts of the parallel track beam of composition rise
Heavy-duty machine track beam, chassis and crawler crane.Although this patent can preferably solve prior art exist deficiency, but due to
It sets up two crawler belts of outrigger so that it is the big increase of width of equipment, so at equipment conveying, or can be subject to when equipment transition
The restriction of road conditions.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, stablizes not it is possible to exist
The problem of foot.
Summary of the invention
This utility model provide a kind of overcome prior art not enough be available for can large-scale engineering machinery voluntarily or military affairs
The chassis that equipment uses.
The chassis of a kind of large-scale engineering machinery of the present utility model, including: what vehicle frame and vehicle frame were fixedly connected is respectively used to
Arranging two track beams of crawler belt, and arrange the crawler belt on track beam, the two ends of each track beam are provided for peace respectively

Inserting the external track frame of track beam, described external track frame is similarly one section of rectangular hollow box beam of cross section, carries out
It is respectively arranged with, with in beam and outside external track frame casing, the guide rail matched, track beam and external track frame set the most respectively
It is equipped with both and is mutually located fixing device.Due to this utility model is by existing track beam end insert installation one
Individual external track frame, so can not only realize setting identical with 201510929021.6 Chinese invention patents on chassis equally
Article four, crawler belt, improves the job stabilization of equipment, and owing to two crawler belts of peripheral hardware can be torn open by removing external track frame
Unload, 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, this utility model can also be at external track frame
Case in guide rail is set again, be inserted into second " external track frame " wherein, the 3rd can be arranged at the homonymy of equipment with this
Bar crawler belt, makes corresponding engineering machinery have six crawler belts the most a plurality of, is so possible not only to be greatly improved engineering machinery
Stability, simultaneously significantly can reduce the pressure to ground by equipment so that it is be more suitable for the operation field in soft geology condition
Close and use.
The chassis of large-scale engineering machinery of the present utility model external track frame and inserting respectively be respectively equipped with on track beam to
A few pin hole matched with alignment pin, is constituted phase between track beam and external track frame by described pin hole and alignment pin
The device that location is fixing mutually.Its structure of this device for positioning and securing of the present utility model is extremely simple, but its fixed effect is very
Reliably, and its dismounting operation also extremely convenient.
In one embodiment on the chassis of large-scale engineering machinery of the present utility model, at the case of track beam Yu external track frame
Internal it is provided with dismountable extension oil cylinder, track beam and external track frame side along its length can be made by the effect of extension oil cylinder
Displacement is produced to position.External track frame can be adjusted after this utility model arranges extension oil cylinder more conveniently and insert crawler belt
The position of beam.
Preferably, the chassis of large-scale engineering machinery of the present utility model can arrange at least one in the casing of external track frame
Group reinforcement, to strengthen the rigidity of external track frame.
The utility model has the advantages 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, simultaneously can
To reduce the grounding pressure of a kind of machinery, and then the stability of complete machine is made to improve；
3) extension that can realize external track frame position by extending oil cylinder is moved, and makes the crawler belt handling extremely letter of peripheral hardware
Just, 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 system simultaneously
The cost made；
5) by arranging reinforcement in external track frame, not only increase the rigidity of external track frame, can subtract again simultaneously
Its weight light；
6) four, the most a plurality of crawler belt can be used due to this utility model, therefore can be selected for common subtracting on market
Speed machine, its overall size is less, and then makes the center of gravity of design chassis structure reduce, and this both can improve the stability of complete machine, simultaneously
Cost and the difficulty of manufacture can be reduced；
7) when using four crawler belts, the engineering machinery that this utility model is combined into can use four type of drive, makes large-scale
Engineering equipment is provided with superior walking and climbing capacity.
