Description
Technical field
The present invention relates to the hydraulic shield support of use under the mine, especially relate to 6.3 meters high supporting hydraulic shield supports.
Background technology
Hydraulic shield support is the support apparatus of underground work indispensability.Along with improving constantly of down-hole mechanical extracting level, to the intensity of hydraulic shield support, highly, safety etc. requires more and more higher.Therefore, to combine the hydraulic shield support of adopting be the problem that those skilled in the art study always to the high-yield and high-efficiency that is used for that possesses that yield load is big, supporting height is high, supporting intensity is big.
Summary of the invention
The object of the invention is to provide a kind of yield load, supporting intensity is big and support height is high 6.3 meters high supporting hydraulic shield supports.
For achieving the above object, the present invention can take following technical proposals:
6.3 meters high supporting hydraulic shield supports of the present invention, it comprises base, is arranged on the Hydraulic Double telescopic column on the described base, described Hydraulic Double telescopic column top and set cap needling are hinged; Set cap rear portion and support caving shield are hinged; Support caving shield bottom is hinged by connecting rod and base; Described set cap is an overall structure, is hinged with the one-level face guard at the set cap front end, is hinged with the secondary face guard at the front end of described one-level face guard; Set cap is provided with one-level wall supporting jack, and the push rod of described one-level wall supporting jack and one-level face guard rear portion are hinged; The one-level face guard is provided with secondary wall supporting jack, and the push rod of described secondary wall supporting jack and secondary face guard rear portion are hinged; Between set cap and support caving shield, be provided with balance jack; Be arranged on the connecting rod that support caving shield bottom and base be hinged and be two front rods, whole back link structure.
The length of set cap front and back ends is arrived than 2.61: 1 in the needling position that is arranged on the described set cap.
Described base is for opening mark structure in the middle of being rigidly connected.
Two side guard boards of described set cap and support caving shield are movable the setting.
The invention has the advantages that working resistance of support is big, can reach more than the 10800KN that supporting intensity reaches more than the 1.10MPa, 6.3 meters of support heights.The column application point is set to 2.61: 1 to back timber front and back ends length ratio, when improving support front end support capacity, has reduced the specific pressure of base front end.The effect of regulating support point of resultant force position, improving the Roof Control effect has been played in the setting of balance jack; When, set cap rear portion pressure more complete when top board was big, balance jack was born pulling force, and will move behind the support force action position, had increased the carrying of support rear portion and had cut the top ability.When fragmentation of top board, when the anterior pressure of set cap is big, balance jack is born pressure, and with the reach of support force action position, has increased the anterior supporting capacity of support.For preventing roof cracking, coal wall caving problem, adopt the long side guard board structure of integral top beam, the long side guard board structure of set cap front end band secondary wall supporting is realized the timely control to top board, has prevented roof collapse.Being provided with little four-bar mechanism between set cap and the one-level face guard, is the radial type structure between the two-stage wall supporting, in time the wall supporting jack is stretched out after coal-winning machine has been adopted coal, rib is lived in the face guard supporting, to prevent coal wall caving, recoverable again face guard when trying to stop people from fighting each other, compact conformation.The connecting rod that support caving shield bottom and base are hinged adopts two front rods, whole back link structure, has improved the torsional property of support, has improved the support resistance to overturning.Base adopts rigidity split pattern, middle bay not to have base arrangement, and base gap bridge back is provided with lifts base mechanism, therefore helps float coal and discharges and lift base.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in the figure, 6.3 meters high supporting hydraulic shield supports of the present invention comprise base 1, be arranged on that cylinder diameter is the Hydraulic Double telescopic column 2 of 400mm on the described base 1, its expansion highly is 6.3m, and working resistance is more than the 10800KN, and supporting intensity is more than the 1.10MPa; Needling 4 on Hydraulic Double telescopic column 2 tops and the set cap 3 is hinged; Set cap 3 rear portions and support caving shield 5 are hinged; Support caving shield 5 bottoms are hinged by connecting rod and base 1; Described set cap 3 is an overall structure, is hinged with one-level face guard 7 at set cap 3 front ends, is hinged with secondary face guard 8 at the front end of described one-level face guard 7, and the expansion of I and II face guard highly is 2.8m; Set cap 3 is provided with one-level wall supporting jack 9, and the push rod of described one-level wall supporting jack 9 is hinged with one-level face guard 7 rear portions by little four-bar mechanism 6; One-level face guard 7 is provided with secondary wall supporting jack 10, and the push rod of described secondary wall supporting jack 10 and secondary face guard 8 rear portions are hinged; Being provided with cylinder diameter between set cap 3 and support caving shield 5 is the balance jack 11 of Φ 230mm; Be arranged on the connecting rod that support caving shield 5 bottoms and base 1 be hinged and be two front rods 12, whole back link 13 structures.Needling 4 positions that are arranged on the set cap 3 are 2.61: 1 to the length ratio of set cap 3 front and back ends; Base 1 is for opening mark structure in the middle of being rigidly connected; Two side guard boards 14,15 of set cap 3 and support caving shield 5 are the bilateral activity structure, and wherein a side is fixing during use gets final product.
