Among the figure, 1, back timber; 2, column; 3, universal joint; 4, caving shield; 5, walking basal seat; 6, back link; 7, drive system; 8, driving wheel; 9, jack is supported in the back; 10, the back is supported; 11, coal-ploughing board; 12, plough coal jack; 13, expansion tightening wheel; 14, caterpillar chain; 15, control system; 16 front rods.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model caterpillar track travelling hydraulic support mainly comprises: jack 9, back support 10, coal-ploughing board 11, plough coal jack 12, expansion tightening wheel 13, caterpillar chain 14, control system 15 etc. are supported in back timber 1, column 2, universal joint 3, caving shield 4, walking basal seat 5, front rod 16, back link 6, drive system 7, driving wheel 8, back.Its concrete structure is as follows:
On the walking basal seat 5 of employing friction plate integral solder case structure drive system 7 is installed, drive system 7 is provided with driving wheel 8, expansion tightening wheel 13 and caterpillar chain 14, expansion tightening wheel 13 and driving wheel 8 are installed on the front-end and back-end of walking basal seat respectively, and caterpillar chain 14 is installed on driving wheel 8 and the expansion tightening wheel 13.The top of walking basal seat 5 is provided with back timber 1, column 2 is articulated between back timber 1 and the walking basal seat 5, be hinged with caving shield 4 and front rod 16 and back link 6 between walking basal seat 5 and the back timber 1: back timber 1 is hinged by universal joint 3 with the upper end of caving shield 4, the lower end of caving shield 4 is hinged with walking basal seat 5 again by front rod 16 and back link 6 respectively, and control system 15 is installed on the walking basal seat 5.Simultaneously, the walking basal seat 5 anterior coal-ploughing boards 11 of installing, coal-ploughing board 11 is hinged with walking basal seat 5 by plough coal jack 12, and walking basal seat 5, coal-ploughing board 11 and plough coal jack 12 are hinged into cam mechanism; Walking basal seat 5 rear portions are installed the back and are supported 10, and the back supports 10, and to support jack 9 by the back hinged with walking basal seat 5, the back support 10 and the back support jack 9 and be hinged into cam mechanism.
In the utility model, " the caterpillar track travelling hydraulic support friction plate integral solder base " that walking basal seat 5 can adopt Chinese utility application (application number 200820218252.1) to be provided.
In the utility model, the structure between 10, " the improvement structure of caterpillar track travelling hydraulic support " that can adopt Chinese utility application (application number 200820218254.0) to be provided are provided for walking basal seat 5 and coal-ploughing board 11, back.
As shown in Figure 1, driving wheel 8 all is upturned with respect to walking basal seat 13 bottom surfaces with expansion tightening wheel 13 and does not contact with roadway floor, can avoid support when work driving wheel 8 and expansion tightening wheel 13 be subjected to the base plate active force; Simultaneously, this structure is also very favourable to the walking of support.When obstacle such as the coal breakage of emitting skin is arranged when the utility model caterpillar track travelling hydraulic support the place ahead, adjust coal-ploughing boards 11 to rational position by plough coal jack 12, the obstruction before removing on the line direction is to guarantee that support moves ahead smoothly.
Shown in Fig. 2～4, because back timber 1 is connected by universal joint 3 with caving shield 4, make and to form certain angle at longitudinal direction and horizontal direction between back timber 1 and the walking basal seat 5, be beneficial to the utility model caterpillar track travelling hydraulic support and realize cutting top and escape, and can well adapt to the fluctuating of roof and floor.
As shown in Figure 5, in the utility model caterpillar track travelling hydraulic support is absorbed in base plate nest hole and can not walk the time, can support 10 actings in conjunction by coal-ploughing board 11 and back, realization is climbed nest and is saved oneself.Simultaneously, in the time of need overhauling support, also can support 10 actings in conjunction the support complete machine is lifted away from the enough height in ground, easy access by coal-ploughing board 11 and back.
Under coal mine in room and pillar mining and the Pillar Recovery process, play bolt support and application specific support apparatus operation is all very slow, become the bottleneck of whole production system, restricting the production capacity of whole system.The alternative bolt support of the utility model caterpillar track travelling hydraulic support and other special-purpose support apparatus, the work of the management work face of making top board is safer, more reliable, more efficient, and can realize that the work plane goaf top plate is with adopting with emitting, solved the unsettled problem of goaf top plate large tracts of land, effectively prevent roof accident, provide safe working space to personnel and equipment, simultaneously, this utility model has very strong escape capability, even if when taking place that directly frame is pressed in the big face inbreak in top, support also can with voluntarily or the mode of mutuum adjutorium realize escape.
