Description
Technical Field
The utility model relates to the field of machinary, especially, relate to mechanical parts technical field, specifically indicate to be used for the big inclination in colliery to combine the end of adopting working face hydraulic support and transfer antiskid.
Background
The geological conditions of underground coal mining working surfaces of coal mines vary widely, wherein the working surfaces with large inclination angles are common, and particularly bring great difficulty to the safe production of the coal mines. Especially, the anti-skidding and anti-falling problems of the hydraulic support are particularly outstanding on a coal mine fully-mechanized mining face, the anti-skidding device of the hydraulic support is single in function, if the common form of a single bottom adjustment jack can only realize posture adjustment after moving the support, the common structural form of double jacks can only realize the anti-skidding problem, and the anti-skidding device with the single function can obviously not meet the change requirement of the coal mining face.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide a bottom adjustment antiskid that is used for the big inclination in colliery to combine to adopt working face hydraulic support, antiskid nature when can guaranteeing the base and remove can realize moving the posture adjustment after the frame again, satisfies coal face change demand.
The utility model discloses a following technical scheme realizes for the big inclination in colliery combines to adopt working face hydraulic support's the end and transfers antiskid, hydraulic support includes along transversely arranging in proper order and the decurrent base of slope, transfer the jack including setting up on the base and two ends that stretch out downwards along base extending direction, transfer the jack along vertically arranging and connect the operating valve that corresponds respectively at two ends, transfer the end that stretches out of jack to articulate at two ends and transfer the roof beam at the end of vertical extension.
When the fully mechanized mining hydraulic support frame moving device is used, in a large-dip-angle working surface, the problem that the hydraulic support frame slides downwards in the frame moving process can occur, in the scheme, before the frame moving, the bottom adjusting jack extends out, so that the bottom adjusting beam is in contact with the base below, then the fixing of the base above is released, the base needing to be moved takes the base below the bottom adjusting beam as a supporting point, then the bottom adjusting jack is driven to contract, and then the hydraulic support frame starts to move forwards, so that the problem that the hydraulic support frame is skid-proof is solved; after the frame is moved, the extending lengths of the two bottom adjusting jacks are adjusted, so that the bottom adjusting beams can make different angles, the self-made posture and angle adjustment after the movement is carried out by taking the lower base as a fulcrum is facilitated, and the change requirement of the coal face is met.
Preferably, the base is provided with a guide sleeve matched with the bottom adjusting jack, and a cylinder body of the bottom adjusting jack is fixed in the guide sleeve.
This preferred scheme is through the setting of guide sleeve, plays the flexible guide effect and the guard action of adjusting jack to the end.
Preferably, the bottom adjusting beam is provided with an oval hinge hole which is in hinge fit with the extending end of the bottom adjusting jack. This preferred scheme makes two bottom adjusting jacks stretch out, contract more smoothly when controlling respectively through the setting of oval-shaped hinge hole.
Preferably, the bottom adjusting jack is provided with a one-way lock with a safety valve.
This preferred scheme is through the setting of one-way lock, guarantees the jack of transferring at the bottom and guarantees effectively holding power when operating condition and accept. Meanwhile, the service life of the bottom adjusting jack can be effectively ensured.
The utility model has the advantages that: in the big inclination working face, the problem that hydraulic support glided can appear in the full-mechanized mining hydraulic support frame moving in-process, and this scheme is before moving the frame, transfers the jack at the bottom to stretch out, makes the bottom transfer the roof beam and the base contact of below, then removes the fixed of the base that is located the top, and the base that needs to remove transfers the roof beam below base as the strong point through the bottom, then transfers the jack shrink at the bottom of the drive, then hydraulic support begins to shift forward. Thereby solving the problem of skid resistance of the hydraulic support; after the frame is moved, the extending lengths of the two bottom adjusting jacks are adjusted, so that the bottom adjusting beams can make different angles, the self-made posture and angle adjustment after the movement is carried out by taking the lower base as a fulcrum is facilitated, and the change requirement of the coal face is met.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
Referring to the attached drawings 1-2, the utility model is used for big inclination of colliery is combined and is adopted working face hydraulic support's end and transfer antiskid, hydraulic support includes along transversely arranging in proper order and slope decurrent base 4, because base 4 sets up on big inclination working face, therefore base 4 is the slope is arranged downwards.
The front end of base 4 is equipped with two guide sleeve 3 that extend along base 4 extending direction, and two guide sleeve are along vertically arranging, and the rigid coupling has the cylinder body of transferring jack 2 with the end in the guide sleeve 3, and the end that stretches out of transferring jack 2 with the end stretches out to the front lower place, and the end that stretches out of transferring jack 2 with two ends articulates has the end of transferring roof beam 1 that vertically extends, transfers roof beam 1 to set up on the end with the end and transfers the oval hinge hole that the end articulated complex of stretching out of jack 2 with the end.
The bottom adjusting jack 2 is provided with a one-way lock with a safety valve.
Specifically, as shown in fig. 2, the transverse direction is the horizontal direction, and the longitudinal direction is the vertical direction.
The utility model discloses when using, in the big inclination working face, the problem that hydraulic support gliding can appear in the full-mechanized mining hydraulic support frame moving in-process, and this scheme transfers jack 2 to stretch out before moving the frame at the end, makes the end transfer roof beam 1 and the base 4 contact of below, then removes the fixed of the base 4 that is located the top, and the base 4 that needs to remove transfers roof beam 1 below base 4 through the end as the strong point, then transfers jack 2 shrink at the bottom of the drive, then hydraulic support begins to move forward. Thereby solving the problem of skid resistance of the hydraulic support; after the frame is moved, the extending lengths of the two bottom adjusting jacks 2 are adjusted, so that the bottom adjusting beams 1 are in different angles, the self-made posture and angle after the movement is carried out by taking the lower base 4 as a fulcrum can be conveniently adjusted, and the change requirement of the coal face is met.
