Abstract
The invention provides a large-mining-height hydraulic support. The problem that an existing large-mining-height hydraulic support is not reasonable in structure, so that production efficiency is low, and supporting intensity cannot be effectively guaranteed is solved. The large-mining-height hydraulic support comprises a base and a top beam arranged above the base. Double telescopic stand columns hinged to the base and the top beam are arranged between the base and the top beam. The back end of the top beam is hinged to a shield beam. A front connecting rod and a back connecting rod hinged to the base and the shield beam are arranged between the back portion of the base and the lower portion of the shield beam. A telescopic beam is arranged on the front portion of the top beam. The front end of the telescopic beam is hinged to three face guard plates which are hinged in sequence. A jack hinged to the top beam and the shield beam is arranged between the back portion of the top beam and the upper portion of the shield beam. The length ratio of the distances from the hinged position of the double telescopic stand columns on the top beam to the front end and the back end of the top beam is 1 : 2.36. The heights of the face guard plates are 57% of the total height from top beam to the base. The ratio of the width of the top beam or the base to the height from the top beam to the base is 1 : 4.16. The weight of the hydraulic support is reduced, and supporting intensity is effectively guaranteed.
Description
Technical field
The present invention relates to coal-mine hydraulic support, be specially a kind of large mining height hydraulic support.
Background technology
Along with the development of large mining and high comprehensive mining technique and the continuous progress of hydraulic support manufacturing process, large-mining-height working surface is by the fully mechanized mining that is following thick coal-layer mining first-selection, and the reasonable increase of support height is also the inexorable trend of large-mining-height working surface development.
Domestic 7 meters of support with great mining height center to center distance are 2.05 meters at present, and weight generally will exceed 60 tons.Higher to mine conditional request, the weight of support is larger, and production efficiency is low, and supporting intensity can not get effective assurance.
Summary of the invention
The present invention can not get because unreasonable structure causes the low and supporting intensity of production efficiency the problem effectively guaranteeing in order to solve existing large mining height hydraulic support, and a kind of large mining height hydraulic support is provided.
The present invention adopts following technical scheme to realize: large mining height hydraulic support, comprise base and the back timber that is positioned at base top, between base and back timber, be provided with the double-telescopic upright post hinged with both, top beam rear end is hinged with caving shield, between base rear portion and caving shield bottom, be provided with the front rod hinged with both and back link, back timber front portion is provided with extensible canopy, extensible canopy front end is hinged with three hinged successively face guards, between back timber rear portion and caving shield top, is provided with the jack hinged with both; On back timber, the hinged place of double-telescopic upright post is 1:2.36 to the Length Ratio of back timber front and back ends, the height of face guard be back timber to 57% of base overall height, the width of back timber or base and back timber to the ratio of substructure height is 1:4.16.
Choosing of large mining height hydraulic support parameter is that repetition test by a large amount of obtains, when alleviating hydraulic support weight, guarantee supporting intensity, overcome existing large mining height hydraulic support and can not get because unreasonable structure causes the low and supporting intensity of production efficiency the problem effectively guaranteeing.
Reasonable in design of the present invention is reliable, when having alleviated hydraulic support weight, has effectively guaranteed supporting intensity, and has improved production efficiency, has advantages of simple in structure, easy to operate and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-base, 2-back timber, 3-double-telescopic upright post, 4-caving shield, 5-front rod, 6-back link, 7-extensible canopy, 8-face guard, 9-jack.
The specific embodiment
Large mining height hydraulic support, comprise base 1 and the back timber 2 that is positioned at base 1 top, between base 1 and back timber 2, be provided with the double-telescopic upright post hinged with both 3, back timber 2 rear ends are hinged with caving shield 4, between base 1 rear portion and caving shield 4 bottoms, be provided with the front rod hinged with both 5 and back link 6, back timber 2 front portions are provided with extensible canopy 7, and extensible canopy 7 front ends are hinged with three hinged successively face guards 8, between back timber 2 rear portions and caving shield 4 tops, are provided with the jack hinged with both 9; On back timber 2, the hinged place of double-telescopic upright post 3 is 1:2.36 to the Length Ratio of back timber 2 front and back ends, the height of face guard 8 be back timber 2 to 57% of base 1 overall height, the width of back timber 2 or base 1 and back timber 2 to the ratio of base 1 height is 1:4.16.
In specific implementation process, back timber 2 is overall structure, and extensible canopy 7 adopts drawer-type structure, and the width of hydraulic support is 1:4.16 with the ratio of height.
