The first end of the first traction rope 2 is connected with the frame driving piece 1, and the second end of the first traction rope 2 is connected with the hydraulic support to be removed.
The frame discharging assembly 3 comprises an uplink platform 31 and a frame loading platform 32 which are connected, the uplink platform 31 and the frame loading platform 32 are respectively provided with a first working surface 311 and a second working surface 321, the second working surface 321 is a horizontal plane, the frame discharging driving piece 1 can be pulled by the first traction rope 2 to be removed, the hydraulic support slides to the second working surface 321 along the first working surface 311 to be discharged, a steering piece 33 is arranged on the frame loading platform 32, and the steering piece 33 is positioned on a traction path of the first traction rope 2 and is used for reversing the first traction rope 2.
According to the quick frame discharging device for the hydraulic support in the withdrawing working face, the frame discharging driving piece 1 pulls the hydraulic support to be withdrawn to the frame loading platform 32 along the ascending platform 31 through the first traction rope 2 so as to realize the direct frame discharging of a group of hydraulic supports to be withdrawn.
Specifically, the frame-removing driving member 1 may be, but is not limited to, a hydraulic cylinder, an earring is disposed on a piston rod of the hydraulic cylinder, the first traction rope 2 may be a steel wire rope, a first end of the steel wire rope is fixed on the earring, and the frame-removing device may be a carrier or a winch in the prior art, which is not expanded here.
For convenience of description, a longitudinal direction of the retracting face along the retracting roadway (or a direction in which a plurality of groups of hydraulic supports to be retracted are arranged in sequence) is defined as a first horizontal direction, and a direction perpendicular to the retracting roadway is defined as a second horizontal direction.
In some embodiments, the racking platform 32 and the ascending platform 31 are arranged in sequence along a second horizontal direction, and the racking drive 1 pulls the second end of the first traction rope 2 along the second horizontal direction.
Specifically, the loading platform 32 and the ascending platform 31 are sequentially arranged along the second horizontal direction, and meanwhile, the unloading driving piece 1 pulls the second end of the first traction rope 2 along the second horizontal direction, so that the loading platform 32, the ascending platform 31 and the hydraulic support to be unloaded are in sequential arrangement positions, and under the cooperation of the unloading driving piece 1, the first traction rope 2 and the steering piece 33, the hydraulic support to be unloaded can be directly slipped onto the second working surface 321 from the first working surface 311 to be unloaded quickly, and therefore, the unloading operation can be completed without adjusting the direction of the hydraulic support to be unloaded by means of a downhole unloading manipulator or a crane, for example, the manual labor intensity is reduced, the unloading efficiency of the hydraulic support to be unloaded is improved, and the production requirement can be met.
In some embodiments, the racking drive 1 pulls the first end of the first traction rope 2 in a first horizontal direction, the first horizontal direction and the second horizontal direction being perpendicular to each other.
Specifically, the frame-discharging driving member 1 pulls the first end of the first traction rope 2 along the first horizontal direction, and pulls the second end of the first traction rope 2 along the second horizontal direction under the cooperation of the steering member 33, so that the hydraulic support to be removed can be directly and sequentially slipped to the structure layout on the frame-loading platform 32 by the ascending platform 31, the usage amount of steel ropes and winches in the frame-discharging process of the hydraulic support to be removed is reduced, the quick frame-discharging operation can be realized, the frame-discharging efficiency is improved, and meanwhile, the layout mode has low requirements on the width of the withdrawing roadway, so that the frame-discharging device is more suitable for being arranged in the withdrawing roadway, and the carrying operation of the hydraulic support to be removed in the withdrawing roadway by frame-discharging equipment such as a carrier is convenient.
In some embodiments, the racking platform 32 has first and second ends opposite along its length, and the racking drive 1 is provided at the first end of the racking platform 32.
The first working surface 311 has first and second ends opposite along its length, the first end of the first working surface 311 engaging the second working surface 321.
The ascending platform 31 is rotatably connected to the second end of the loading platform 32 and has an upper frame position and a loading position, in the upper frame position, the second end of the first working surface 311 is lower than the second working surface 321, in the loading position, the second end of the first working surface 311 is equal to or higher than the second working surface 321, and the first working surface 311 is abutted with the hydraulic support to be removed.
Specifically, by rotating the ascending platform 31 on the loading platform 32, a loading position and a loading position can be formed therebetween, so that the hydraulic support to be removed can smoothly slide from the first working surface 311 to the second working surface 321 at the loading position to complete the loading operation, and is reliably temporarily stored on the loading platform 32 at the loading position.
Meanwhile, it can be understood that, since the second working surface 321 is a horizontal plane, in the up-frame position, the height of the second end of the first working surface 311 is lower than that of the second working surface 321, and the hydraulic support to be removed can be pulled to slide onto the second working surface 321 along the first working surface 311, the whole up-frame platform 31 is inclined towards one side far away from the loading platform 32 in the up-frame position, so as to form a climbing structure therebetween, and thus, the hydraulic support to be removed is not required to be lifted onto the loading platform 32 by means of a downhole removing mechanical arm or crane, for example, but can be pulled to climb onto the loading platform 32 along the declining up-frame platform 31 under the cooperation of the removing driving member 1, the first pulling rope 2 and the steering member 33, thereby simplifying the removing operation of the hydraulic support to be removed.
In addition, in the loading position, since the height of the second end of the first working surface 311 is equal to or higher than the height of the second working surface 321, and the first working surface 311 abuts against the hydraulic support to be removed, a reliable support for the hydraulic support to be removed can be formed between the ascending platform 31 and the loading platform 32.
Taking the frame-out driving piece 1 as a hydraulic cylinder for example, the cylinder body and the frame-loading platform 32 are kept in a relatively fixed position, and at the moment, the piston rod of the hydraulic cylinder and the length of the steel wire rope of the hydraulic support to be removed are kept unchanged, so that the frame-out operation of the hydraulic support to be removed is carried out by adopting a traction mode that the frame-out driving piece 1 pulls the first end of the first traction rope 2 along the first horizontal direction under the condition that the frame-out driving piece 1 pulls the second end of the first traction rope 2 along the second horizontal direction, the whole structure of the frame-out device is compact, and meanwhile, compared with a mode that the hydraulic support to be removed is pulled out one by adopting winch and steel wire rope to match in the prior art, the whole use length of the steel wire rope is reduced, the problem that the personnel safety of operators is endangered due to elastic withdrawal caused by huge traction force and easy breakage when the length of the steel wire rope is longer is avoided, the construction safety coefficient is ensured, meanwhile, the difficulty of manual dragging, coiling and connection of the steel wire rope of operators is greatly reduced.
In some embodiments the diverting member 33 is a diverting pulley provided in a middle position of the first end of the racking platform 32 around which the first traction rope 2 passes for diverting the second end of the first traction rope 2.
