Abstract
The utility model provides an integrally-placed hydraulic support which comprises a base box, a top beam, a shield beam, a front beam, a telescopic front beam, a front connecting rod, a rear connecting rod, a front stand column, a rear stand column and a stop rod. The top beam is supported above the base box through the front stand column and the rear stand column, a B end of the top beam is hinged to an A end of the shield beam, and an A end of the top beam is hinged to a B end of the front beam; an A end of the front beam is hinged to a B end of the telescopic front beam, an A end of the telescopic front beam is hinged to a B end of a protection assisting plate, and the protection assisting plate is connected with the telescopic front beam through a hydraulic jack to achieve the fact that the protection assisting plate swings relative to the telescopic front beam; the shield beam is connected with the base box through the front connecting rod and the rear connecting rod, a B end of the shield beam is hinged to an A end of a tail beam, and the tail beam is connected with the shield beam through another hydraulic jack to achieve the fact that the tail beam swings relative to the shield beam; an insertion plate is connected with a B end of the tail beam through a hydraulic telescopic jack, so the insertion plate can stretches out and draws back relative to the tail beam.
Description
Technical field
The utility model relates to the coal-mining technique field, is specifically related to a kind of integrated caving hydraulic support.
Background technology
Along with the change of coal winning technology, MKSP-FSC40PL8 type 4/560 support that former Mitsui three pond companies produce is eliminated.But this support integrality is good, and overall structure, each swivel pin, Kong Junwu distortion, nothing cracking still remain intact state.If will improve on the basis of these supports, and continue to be applied to produce, will save a large amount of funds.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of integrated caving hydraulic support.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of integrated caving hydraulic support comprises base member case, back timber, caving shield, front-axle beam, cantilever extension, front rod, back link, front column, rear column and fixed pole; Back timber is supported in by front column and rear column above base member case, and the A end of the B of back timber end and caving shield is hinged, and the A end of back timber and the B end of front-axle beam are hinged; The A end of front-axle beam and the B of cantilever extension are hinged; The A end of cantilever extension and the B end of face guard are hinged, and face guard connects to realize that by hydraulic jack and cantilever extension the relative cantilever extension of face guard swings; Caving shield is connected with base member case with back link by front rod, and the B end of caving shield and the A end of tail boom are hinged, and tail boom connects to realize that by hydraulic jack and caving shield the relative caving shield of tail boom swings; Plate is connected the connection of B end to realize the flexible of the relative tail boom of plate with tail boom by the hydraulically extensible jack.
Above-mentioned integrated caving hydraulic support, base member case is structure as a whole.
Above-mentioned integrated caving hydraulic support, front rod length are 1390mm; Back link length is 1203mm.
Above-mentioned integrated caving hydraulic support, front rod length are 1315mm; Back link length is 1555mm.
The utility model has increased the face guard that is articulated in cantilever extension, tail boom and the telescopic plate of caving shield swing relatively.Tail boom and plate can be completed top coal caving.Face guard can withstand rib in support the place ahead.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the utility model:
Fig. 1 is schematic diagram of the present utility model.
In figure, 3 fixed poles, 4 front rods, 5 back links, 7 base member case, 8 back timbers, 9 caving shields, 10 front columns, 11 rear columns, 12 front-axle beams, 13 cantilever extensions, 14 face guard 15 tail booms, 16 plates.
The specific embodiment
As shown in Figure 1, a kind of integrated caving hydraulic support comprises base member case 7, back timber 8, caving shield 9, front-axle beam 12, cantilever extension 13, front rod 4, back link 5, front column 10, rear column 11 and fixed pole 3.Back timber is supported in by front column and rear column above base member case, and the A end of the B of back timber end and caving shield is hinged, and the A end of back timber and the B end of front-axle beam are hinged.The A end of front-axle beam and the B of cantilever extension are hinged.The A end of cantilever extension and the B end of face guard 14 are hinged, and face guard connects to realize that by hydraulic jack and cantilever extension the relative cantilever extension of face guard swings.Caving shield is connected with base member case with back link by front rod, and the B end of caving shield and the A end of tail boom 15 are hinged, and tail boom connects to realize that by hydraulic jack and caving shield the relative caving shield of tail boom swings.Plate 16 is connected the connection of B end to realize the flexible of the relative tail boom of plate with tail boom by the hydraulically extensible jack.
Existing standoff base member case is split-type structural, and bulk strength is low, and base member case of the present utility model is structure as a whole, and has improved the intensity of base member case.
Particularly, front rod length is 1390mm; Back link length is 1203mm.
Particularly, front rod length is 1315mm; Back link length is 1555mm.
