Abstract
The utility model discloses a comprehensive mining hydraulic support of a complete top plate of a light type thin coal seam, comprising a hydraulic supporting column as well as a pushing hydraulic cylinder with an oil cylinder and a piston, wherein the bottom part of the hydraulic supporting column is provided with a base, the oil cylinder is connected with the base and the piston is connected with a scraper conveyer. The comprehensive mining hydraulic support of the complete top plate of the light type thin coal seam is a mining working surface support which can increase the integrity and rigidity of a supporting system, enlarge the movable space, reduce the weight and cost of the support, improve safety insurance degree and adapt to the condition of the hard top plate of the thin coal seam.
Description
Technical field
The utility model relates to comprehensive mechanical coal mining face timbering equipment under a kind of coal mine.
Background technology
Comprehensive mechanical coal mining face timbering equipment under the coal mine generally has for the exploitation supporting method of girdle: hydraulic prop and hydraulic support for low coal seam.The separate effect of every pillar of hydraulic prop work plane, independent moving, globality is poor, occur easily crooked, bore phenomenon such as the end.Hydraulic support for low coal seam commonly used generally all has complete top board and base, has reduced effective activity space, and single frame weight is big, and cost height, price are expensive.
The utility model content
The purpose of this utility model provides a kind of globality and rigidity that increases support system, increases activity space, reduces weight support frame and cost, improves the coal-face supporting of safety guarantee degree and adaptation girdle tight roof condition.
For achieving the above object, the utility model adopts following technical scheme: the complete top board comprehensive mining hydraulic bracket of light-duty girdle, comprise hydraulic prop, and the bottom of hydraulic prop is provided with base.
Also comprise the passing hydraulic cylinder that has oil cylinder and piston, oil cylinder links to each other with base, and piston links to each other with scratch board conveyor.
The top of described hydraulic prop is provided with pallet.
Described base is the frame type base, and 4 hydraulic props are positioned at four jiaos of base.
The beneficial effects of the utility model are: 4 hydraulic props are combined integrated, link by the frame type base, and do not establish support and protect top portion, make full use of support space, both strengthened the globality of support, increased the lifting surface area of base again, prevent that effectively support from boring the end.Can realize rising automatically or bouncing back falling the function of frame by hydraulic prop and pallet, be convenient to roof supporting.When hydraulic prop rises roof supporting, can be used as fulcrum, start and pass hydraulic cylinder, piston is protracted promote the scratch board conveyor reach, realized the function of automatic passing scratch board conveyor; When top board is left in the hydraulic prop reduction, can start and pass hydraulic cylinder with scratch board conveyor as fulcrum, by oil cylinder traction base and hydraulic prop reach.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
By the complete top board comprehensive mining hydraulic bracket of light-duty girdle shown in Figure 1, comprise that 5,4 hydraulic props 5 of 4 hydraulic props that are provided with on square frame type base 2 and the base 2 are arranged at four jiaos of base 2 respectively, and the top is equipped with pallet 1.Also comprise the passing hydraulic cylinder that has oil cylinder 3 and piston 4, oil cylinder 3 links to each other with base 2, and piston 4 links to each other with scratch board conveyor.
During use, can realize rising automatically or bouncing back falling the function of frame, be convenient to roof supporting by hydraulic prop 5 and pallet 1.When hydraulic prop 5 rises roof supporting, can be used as fulcrum, start and pass hydraulic cylinder, piston 4 is protracted promote the scratch board conveyor reach, realized the function of automatic passing scratch board conveyor; When top board is left in hydraulic prop 5 reductions, can start and pass hydraulic cylinder with scratch board conveyor as fulcrum, by oil cylinder 3 traction bases and hydraulic prop reach.
