Abstract
The invention relates to the field of a crawler walking mechanism, and particularly to a walking mechanism of a fully-mechanized coal winning machine. The walking mechanism of the fully-mechanized coal winning machine comprises a crawler frame, a driving wheel, a guiding wheel and a crawler plate. The walking mechanism of the fully-mechanized coal winning machine furthermore comprises a bearing rack which is arranged below the crawler frame between the driving wheel and the guiding wheel and is made of wearing-resistant steel plate, and positioning blocks which are respectively welded in front of and behind the top of the bearing rack. The lower part of the crawler frame is provided with positioning troughs which are in snapped cooperation with the front positioning block and the back positioning block. Compared with the prior art, the walking mechanism of the fully-mechanized coal winning machine has advantages of low fabrication cost, simple and convenient mounting, and simple maintenance. A good effect of no accident in ten-kilometer winning distance is realized in an actual use process, thereby reducing a resistance in walking of the fully-mechanized coal winning machine, reducing labor intensity of maintenance personnel, prolonging use time of the walking mechanism of the fully-mechanized coal winning machine, and saving comprehensive cost. Regular conveying of the walking mechanism of the fully-mechanized coal winning machine to a wellhead for maintenance is replaced by daily inspection, thereby reducing time in detachment, conveying and mounting of the equipment. The walking mechanism is suitable for various types of fully-mechanized coal winning machines.
Description
Technical field
The present invention relates to creeper undercarriage field, specifically a kind of fully-mechanized digging machine traveling gear.
Background technology
Along with the round Realization of mechanization mine, fully-mechanized digging machine is dominate in coal production, and it mainly comprises traveling gear, cutting units, body, hydraulic pressure portion and electrical part etc.Wherein, traveling gear is one of very important parts of fully-mechanized digging machine.Existing fully-mechanized digging machine traveling gear (as shown in Figure 1) comprises track frame 1, be installed on the caterpillar wheel 4 of the drive wheel 2 of track frame 1 lateral rear, the guide wheel 3 of exterior front and outer lower portion respectively, be surrounded on the caterpillar block 5 on drive wheel 2, guide wheel 3 and caterpillar wheel 4.Traveling gear adopts caterpillar wheel 4 and caterpillar block 5 rubs to produce friction force and completes walking function, and fully-mechanized digging machine is mainly supported integrally on bottom surface by the function of traveling gear, transmission and carry various power or the moment that road surface acts on caterpillar block 5.The quality of caterpillar wheel 4 directly affects the serviceability of traveling gear and the smooth running of complete machine.
Along with the continuous increase of fully-mechanized digging machine fuselage, the weight that traveling gear bears also increases thereupon, and caterpillar wheel 4 can not bear load, frequently changes caterpillar wheel 4 when causing fully-mechanized digging machine to run, and impact is produced.And owing to being subject to the restriction in space when changing, there is great potential safety hazard.
Summary of the invention
The present invention, in order to solve fully-mechanized digging machine caterpillar wheel Problems existing, provides a kind of fully-mechanized digging machine traveling gear.
The present invention is achieved by the following technical solutions: fully-mechanized digging machine traveling gear, comprise track frame, drive wheel, guide wheel and caterpillar block, also comprise the heavy frame be made up of wear-resisting steel plate of the track frame outer lower portion be installed between drive wheel and guide wheel, be welded in the locating piece before and after a heavy top of the trellis respectively, described track frame bottom has the positioning groove with front and back two locating piece snap-fit engagement.
During concrete use, described wear-resisting steel plate adopts 40Mn2 high abrasion resisting material to make, and the width of a heavy frame is identical with track shoe width.
Fully-mechanized digging machine traveling gear of the present invention, compared with prior art, has following beneficial effect:
(1) cost is low, installs simple and convenient, keeps in repair easy, achieves the good result of " zero accident " of 1 myriametre digging footage in actual use;
(2) resistance when fully-mechanized digging machine being walked reduces, and reduces the labour intensity of service personnel, extends the period of service of fully-mechanized digging machine traveling gear, saved integrated cost;
(3) make the regularly upper well maintenance of fully-mechanized digging machine traveling gear, change routine inspection into, decrease dismounting and convert the time of fortune, erecting equipment, be applicable to the fully-mechanized digging machine of various model;
(4) area of contact due to caterpillar wheel and caterpillar block is little, be easy to make caterpillar block local pressure damage caterpillar block, and the area of contact of a heavy frame and caterpillar block is large, when caterpillar block stressed large time prop up heavy frame and can share some pressure for caterpillar block, the holding capacity of effective minimizing caterpillar block, extends the period of service of caterpillar block;
(5) when changing caterpillar block, be subject to down-hole space constraint, lift large part and there is very large potential safety hazard, and use the present invention can reduce these links, there is not potential safety hazard;
(6) the present invention is Demountable, effectively saves the repair time, increases work efficiency;
(7) reduce the labour intensity of service personnel, decrease service personnel.
