Description
Technical field
The utility model belongs to coal-winning machine technical field, particularly relates to a kind of walking mechanism of chainless haulage flitting.
Background technology
Along with the development of mining mechanization, coal-winning machine has very important effect in Modern Coal industry, and it is the basis that extensive fully-mechanized mining working is mined.Along with scientific computer is in the application of coal industry, coal-winning machine, also towards automation, has the future development of high reliability and self-diagnostic function, to adapt to the job requirement under the geological conditions of coal mine work area complexity.Coal-winning machine is mainly made up of parts such as motor, tractive unit, cutting units, electrical system, hydraulic system and fixtures.The running part of coal-winning machine is the critical component of coal-winning machine, and it not only bears the weight of the coal-winning machine in coal-winning machine when walking, but also the moment of flexure of cut counter-force to walking mechanism on cylinder while bearing coal-winning machine coal cutting.And the most of Dou Shi chainless haulage of the running part of modern coal-winning machine mechanism, this mode of traction can meet most of geology condition to the requirement of mining.Conventional chainless hauled shearer mode of traction has gear-pin rail type, roller-rack type, compound gear-rack type and sprocket wheel-rack rails type.
The coal-winning machine of current domestic use, gear-Xiao Guixing chainless haulage mechanisms that adopt more, conventionally have two cover walking driving mechanisms in the close goaf of coal-winning machine one side, by being arranged on the each self-driven road wheel of walking case near head, tail, this road wheel engages with the pin rail being laid on drag conveyor, thereby drives the movement of coal-winning machine along drag conveyor.Because being subject to the restriction of working space, the volume of road wheel, the piston shoes that play the guiding role and pin rail is all very little, although the key position of these key components and parts has used wear-resisting and high-strength material, but still is difficult to meet the requirement of work plane to its intensity.The main failure mode geared surface wearing and tearing of road wheel, flank of tooth Plastic Flow, improper broken teeth etc.Guide slip shoe was also because destructions such as wearing and tearing, tear was lost efficacy very frequent.Pin rail was because the destructions such as pin tooth excessive wear were lost efficacy.The ambient conditions very severe that coal-winning machine is mined at fully-mechanized mining working, has splashing of coal particles and sandstone, also have the erosion of sour water, and its transmission belongs to open type gear driving, the as easy as rolling off a log like this abrasive wear that makes the coal grains of sand cause road wheel and pin rail; In low-speed heavy-loaded gear transmission, position, flank of tooth contact position has great contact stress, and in the time that it exceedes the fatigue limit allowable of material, Plastic Flow will occur the flank of tooth; Uneven due to floor, can shake when coal-winning machine is walked on drag conveyor, and concussion that the weight of hundreds of ton causes is as easy as rolling off a log causes the road wheel gear teeth and the pin rail pin tooth destruction that fractures.
Current many coal enterprise are in order to improve output, all to use high-power chainless hauled shearer, although this has improved productivity ratio, but, as shown in Figure 1, during because of coal mining machine roller 13 coal cutting, coal seam has very big cut counter-force to it, final this cut counter-force is delivered to road wheel 10, support on the pin rail 9 of piston shoes 4 and coal-winning machine 2, and the application point of this cut counter-force is longer to the distance of walking wheel of coal cutter 10, so, the moment of flexure acting in walking mechanism will be very large, consider the destruction reason of above-mentioned traveling mechanism of coal mining machine, this has reduced the application life of traveling mechanism of coal mining machine to a great extent.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of walking mechanism of chainless haulage flitting is provided.When the walking mechanism of this chainless haulage flitting effectively reduces coal-winning machine work, on cylinder, the moment of flexure of cut counter-force to traveling mechanism of coal mining machine and pin rail, has improved application life.
For achieving the above object, the technical solution adopted in the utility model is: the walking mechanism of chainless haulage flitting, it is characterized in that: comprise the guide slip shoe being arranged in Coal Winning Machine, support piston shoes, for with drag conveyor on pin rail engagement fit road wheel and for the power set of ground-engaging wheel, described guide slip shoe and support piston shoes are all arranged on the bottom of Coal Winning Machine, described road wheel is rotatably installed in the bottom of Coal Winning Machine and is positioned at the top of described pin rail, the side of described guide slip shoe and pin rail is and is slidably matched, the end face of the baffle of described support piston shoes and drag conveyor is and is slidably matched, described guide slip shoe is arranged on and supports between piston shoes and the cylinder of coal-winning machine, and described guide slip shoe is near cylinder.
The walking mechanism of above-mentioned chainless haulage flitting, is characterized in that: in described Coal Winning Machine, be provided with the walking case for receiving described power set.
The walking mechanism of above-mentioned chainless haulage flitting, is characterized in that: described walking case be positioned at guide slip shoe directly over, and between Coal Winning Machine and cylinder.
The utility model compared with prior art has the following advantages: by walking case, road wheel and guide slip shoe being all located to the same side side on the lower side of coal mining machine roller, like this, coal-winning machine is in the time of craspedodrome coal cutting, cut counter-force on cylinder has shortened many to the horizontal range of road wheel and guide slip shoe, therefore cut counter-force has also reduced many to the moment of flexure of road wheel, guide slip shoe and pin rail.So under same cut counter-force effect, the application life of this walking mechanism can be longer.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
