Abstract
The invention relates to a four-drive running mechanism for a development machine, which is composed of two groups of track systems. Each group of track system mainly includes a track, a drive wheel, two guiding drive wheels and a wheel support saddle thereof, a tightener, a running bracket, drive power sources and a decelerator. The running mechanism is provided with four drive power sources to simultaneously drive the two guiding drive wheels and two back drive wheels to provide ultra-strong driving force for the development machine and simultaneously reduce the height of the gravity center of a chassis of the development machine, greatly improve the braking capacity and response speed of a running part and prolong the service life of the track.
Description
Technical field
The present invention relates to a kind of four-drive traveller of development machine,, belong to mining machinery for development machine provides superpower walking driving force.
Background technology
The running part of prior art development machine all is to adopt two drive forms, and there is the driving power source two groups of traveling crawler back, drives driving wheel, drives crawler belt, and front-wheel is a driven pulley, only plays support, guiding and tension, does not have power source directly to drive.Because two-wheel drive drives power and all bears output by two driving wheels, the driving force wretched insufficiency.Driving force is not enough can to produce following problem: 1. when development machine was advanced (the particularly driving and the clear end), running resistance was bigger, can cause the vexed car of walking power source, can make when serious to drive the power source component wear; 2. the development machine climbing capacity is not strong, can not adapt to the large inclination working surface operation; 3. be short of power development machine adaptation base plate limit of power is dwindled.
Drive power simultaneously and all bear output by two driving wheels, require driving wheel and transmission reduction gearing thereof to possess higher intensity, rigidity and other mechanical performances and satisfy high-power driving, in order to reach this requirement, the design modulus of crawler belt sprocket wheel must strengthen, thereby cause in the set of volumes excessive, the chassis center of gravity is higher, also greatly reduces the climbing capacity of development machine.
Two traditional drive form running parts when advancing just up and down one-sided crawler belt be subjected to pulling force, produce thus simultaneously that crawler belt is stressed irregular up and down, have a strong impact on crawler belt application life.
Two drive the running part braking point has only two, must transmit brake force by crawler belt, and the one, the braking force distribution inequality is a little less than the brake force; The 2nd, braking response is slow, long time-delay is arranged, promptly no matter advance or retreat, pine is executed when the side crawler belt is strained fully could bring into play braking ability the biglyyest, so two to drive running parts be totally unfavorable for the bad work plane of base plate condition.
Summary of the invention
The purpose of this invention is to provide a kind of four-drive traveller of development machine, it can strengthen the walking driving force, reduces integral body and height of C.G., equal permanent distribution crawler belt pulling force, strengthen stopping power and shorten the braking response time.
The present invention is achieved in that four-drive traveller of development machine, constitute by two groups of caterpillar systems, every group of caterpillar system comprises crawler belt, driving wheel, directive wheel, the directive wheel bearing, mobile roof support, drive power source and reducer, driving wheel connects with the mobile roof support rear portion by reducer, directive wheel connects with the directive wheel bearing by reducer, the directive wheel bearing connects with mobile roof support is anterior again, crawler belt is plug-in to be installed on driving wheel and the directive wheel, body is fastening connects with driving for the mobile roof support of two groups of caterpillar systems, wherein, described directive wheel is the same with driving wheel, and driving power source and reducer also have been installed, and such two groups of caterpillar systems have four driving wheels.
On the such scheme basis, the driving power source of described four driving wheels can be a hydraulic motor, also can be motor.
In addition, described directive wheel bearing and mobile roof support are to be slidingly connected, and can move forward and backward; Also be provided with a cover tensioning apparatus between directive wheel bearing and the mobile roof support, in order to regulate track tension.
Advantage of the present invention is: 1. export owing to driving force is distributed on four driving wheels, the power of transmission that each driving wheel is born relative two drive to reduce near half, so the monnolithic case of 4 wheel driven running part is less than two and drives, the chassis center of gravity effectively reduces, and has improved climbing capacity and to the adaptive capacity of work plane base plate; 2. crawler belt was subjected to same pulling force about 4 wheel driven moved when advancing, and just the one-sided pulling force of crawler belt was divided into crawler belt bilateral pulling force, made improve half the application life of crawler belt; 3. four-drive traveller is corresponding takes 4 brakings, has increased substantially the stopping power of running part, has shortened the braking response time effectively simultaneously.

The specific embodiment
Describe most preferred embodiment of the present invention in detail below in conjunction with accompanying drawing:
Shown in the vertical view of the front view of Fig. 1 four-drive traveller of development machine of the present invention and Fig. 2 four-drive traveller of development machine of the present invention, four-drive traveller of development machine of the present invention is made of two groups of caterpillar systems, caterpillar system specifically is made up of following component as shown in Figure 2: crawler belt 1, front reduction gear bolt 2, preceding (guiding) driving wheel 3, preceding power source 4, preceding (guiding) driving wheel bolt 5, front reduction gear 6, front wheel driving frame 7, front wheel driving bearing 8, tensioning apparatus 9, mobile roof support 10, rear drive sprocket 11, back reducer 12, back power source 13, back reducer bolt 14, rear drive sprocket bolt 15, wherein: back power source 13 is fixedly connected with back reducer 12, rear drive sprocket 11 is connected with back reducer 12 by rear drive sprocket bolt 15, forms a rear drive unit; Rear drive unit connects with mobile roof support 10 rear portions with back reducer bolt 14; Preceding power source 4 is fixedly connected with front reduction gear 6, and front driving wheel 3 is connected with front reduction gear 6 by front driving wheel bolt 5, is fixed on the front wheel driving frame 7 by front reduction gear bolt 2 again, forms a front drive unit; Front wheel driving frame 7 in the front drive unit inserts in the chute of front wheel driving seat 8, can move forward and backward, and front wheel driving frame 7 rear portions head on tensioning apparatus 9, and front wheel driving seat 8 is fixedly connected with the front portion of mobile roof support 10; Plug-in same crawler belt formed one group of complete caterpillar system like this on forward and backward driving wheel.
Two groups of caterpillar system bilateral symmetry are configured in development machine body both sides, and two mobile roof supports and the fastening (see figure 1) that connects of driving body constitute four-drive traveller of development machine of the present invention.
