Description
Technical field
It the utility model is related to a kind of creeper undercarriage, more particularly to a kind of simple creeper undercarriage of excavator.
Background technology
Mechanical digging machine is as a kind of winning equipment, more suitable for open coal mine, nonmetallic ore and non-ferrous metal mineral reserve
Exploitation in, although China mini-excavator develops to hydrofication direction at present, nitrogen large hydraulic excavator is due to by ore deposit
With the limitation of the condition of excavation and Hydraulic Elements, it there are the accuracy of manufacture and require high, maintaining is complicated, and failure is not easy to find,
The features such as field maintenance difficulty, therefore thrown away in large-scale excavating equipment based on use mechanically, this excavator can be not only used for coal
The excacation of ore, but also it is each can be completed by the replacing of equipment for lifting, loading, crawl, big plate, drilling etc.
Kind operation, it is indispensable visual plant in current various strip mining transformations.
In order to realize the requirement of its periodic job, mechanical digging machine is typically provided with equipment, slewing equipment, power
Device, transmission mechanism, running gear and servicing unit etc., for the running gear of mechanical digging machine, there are crawler type, tire
Formula, legged etc., although rubber-tyred, legged running gear respectively have its feature, crawler unit is due to good
It is strong to the adhesive force of soil by property, it is smaller than pressure, rugged road surface is adapted to, plus with good mobility,
It need not lay or prepare road to come by shoal, narrow ditch, abrupt slope or other barriers, so crawler type walking mechanism is machinery
The most important form of formula excavator.
Crawler type walking mechanism is made up of cterpillar drive, suspension and frame.Wherein running gear mainly includes carrying out
Band, driving wheel, thrust wheel, support sprocket wheel, tensioning wheel and tension buffer device etc..The structure choice of caterpillar walking mechanism is
Determined according to the purposes of vehicle.Crawler type walking mechanism designed by this paper is mainly used in not level walking and backman
Make personnel and carry out operation.Therefore, the general structure of crawler type walking mechanism is unsuitable excessive, should be on the basis for meeting job requirements
On, it is designed as far as possible with the small-sized principle that turns to.
The content of the invention
The utility model provides that one kind action is convenient to achieve the above object, adapts to the digging of various complicated landform environment
The simple creeper undercarriage of pick machine.
Technical solution adopted in the utility model：
The simple creeper undercarriage of excavator, including crawler belt, track frame, driving wheel, thrust wheel, front and rear thrust wheel support with
And vehicle frame, track frame are in " ┷ " type, the horizontal component of track frame is fitted with arm-tie in vertical portion both sides respectively, and it is fixed that arm-tie passes through
Position latch is fixed, and driving wheel is placed in track frame top, and two thrust wheels are placed in track frame both sides, and crawler belt is looped around driving wheel and two
On individual thrust wheel, preceding thrust wheel support is connected with thrust wheel, and vehicle frame is connected by attachment means with preceding thrust wheel support, connection dress
Put and be connected to by connecting plate on the axle center of driving wheel, rear thrust wheel support connects two thrust wheels, is propped up on rear thrust wheel support
Support has rolling bearing units, and crawler belt is looped around on rolling bearing units and two thrust wheels, and the other end of vehicle frame is fixed on rolling bearing units with after
On thrust wheel support.
Described crawler belt is that form closed-loop is linked up with connecting pin by creeper tread.
Described driving wheel is gear ring type driving wheel.
The beneficial effects of the utility model：The utility model applicability is wide, exquisiteness simple in construction, can be used as a variety of excavators
Walking mechanism, the corresponding two sets of caterpillar belt structures of front and back wheel are easy to modular repair and convenient action, being capable of more easily Crossing ditch etc.
Complicated landform environment, ability is climbed up and over stronger, and the arm-tie installed on track frame is easy to adjust support wheel spacing, avoids
Track wear is loose and causes derailment occurring.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1- rolling bearing units；2- vehicle frames；3- attachment means；4- connecting plates；5- driving wheels；6- track frames；7- branch weights
