Abstract
The utility model relates to a set of fully-mechanized coal mining face hydraulic support retracting equipment. The retracting equipment mainly comprises an inclined arc platform, a main platform, walking structures, lug seat devices, a top prop, a guide wheel, a side prop and a lifting platform and is a retracting device of a coal mine fully-mechanized coal mining face complete set of equipment. The fully-mechanized coal mining face hydraulic support retracting equipment solves the problems that a pushing hydraulic cylinder of existing retracting equipment cannot be conveniently manufactured, the existing retracting equipment is huge in size and bolts for connection are prone to fracture. The fully-mechanized coal mining face hydraulic support retracting equipment is provided with lug seats, a hydraulic support is moved onto the retracting equipment through a pushing device of the hydraulic support, the equipment is provided with three lug seats which are used in sequence, and thus the hydraulic support can rotate by a certain angle. An inclined shovel plate and an arc platform are welded together, bolt connection is saved, and the structure is more compact and simpler. The inclined arc platform and the main platform are connected through wedge-shaped structures and hinge pins; the main platform and the lug seat devices are connected through wedge-shaped structures and hinge pins; the main platform and the lifting platform are connected through wedge-shaped structures and hinge pins, and thus connection is firmer. The fully-mechanized coal mining face hydraulic support retracting equipment has the advantages of being simple in structure and high in practicality.
Description
Technical field:
The utility model relates to a kind of device that withdraws of coal mine fully-mechanized mining working a complete set of equipment, especially coal mine fully-mechanized mining face hydraulic support withdrawing device.
Background technology:
Hydraulic support is most widely used equipment in mine.In fully-mechanized mining working a complete set of equipment, hydraulic support quantity is many, and volume is large, weight is large, thus hydraulic support recall Comparision difficulty.The existing equipment that withdraws, majority utilizes pulley push unit that hydraulic support is moved on the equipment of withdrawing, and recycling winch pull rope makes hydraulic support 90-degree rotation; Because the hydraulic cylinder of hauling block is longer, be not only difficult to manufacture, also increase the overall structure of the equipment that withdraws, and connected with bolt between parts, in traction hydraulic support process, bolt is subject to shearing force, easy fracture.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, connect fully-mechanized mining working hydraulic pressure firm and easy to use and withdraw equipment.
The purpose of this utility model is achieved in that a kind of fully-mechanized mining working surface hydraulic support withdraws equipment, is made up of oblique arc platform, main platform, walking structure, support top, ear base device, lifting platform, a neighbour, directive wheel.Tiltedly between arc platform and main platform, be connected with wedge structure and bearing pin; Between main platform and ear base device, be connected with wedge structure and bearing pin; Between main platform and lifting platform, be connected with wedge structure and bearing pin.Wedge structure is connected more firm than bolt connection with bearing pin, not easy fracture.
Withdraw in equipment at above-mentioned fully-mechanized mining working surface hydraulic support, tiltedly arc platform front portion is oblique structure, and rear portion is the platform of arc, is welded by plurality of plates, and there is fillet swash plate and arc junction, and tiltedly there is reinforcing rib arc platform inside.
Withdraw in equipment at above-mentioned fully-mechanized mining working surface hydraulic support, ear base device has been installed two ear holder structures, and ear holder structure is rounded down.
Withdraw in equipment at above-mentioned fully-mechanized mining working surface hydraulic support, lifting platform has an ear holder structure, and ear holder structure is rounded down.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
(1) between parts, be connected with bearing pin with wedge structure, connect more reliably not easy fracture.
(2) tiltedly shovel board becomes oblique arc platform with arc platform welding, has saved bolt connection, and more firm after welding, and volume reduces.
(3) ear base device uses rope to utilize hydraulic support from moving, and has saved passing hydraulic cylinder, and device structure is simpler, easy to use.
(4) on lifting platform, also have an ear holder structure, three ear holder structures use successively, can save time, laborsaving, safe hydraulic support is moved to and withdrawn on platform, and the pull rope of recycling winch makes its 90-degree rotation.
Brief description of the drawings:
Further illustrate this use is novel below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model structural representation;
Fig. 2 is ear holder structure schematic diagram;
Fig. 3 is wedge structure and bearing pin connection diagram;
1. oblique arc platforms in figure, 2. main platform, 3. walking structure, 4. support top, 5. ear base device, 6. lifting platform, 7. a neighbour, 8. directive wheel.
Detailed description of the invention:
In Fig. 1, on ear base device 5, there is ear holder structure, hydraulic support to be withdrawn is parked in the swash plate dead ahead of oblique arc platform 1, the ear seat in hydraulic support dead ahead and hydraulic support push unit is connected together with rope.Utilize hydraulic support self-advancing Device traction hydraulic support, hydraulic support is moved on the equipment of withdrawing; While moving on to certain position, change another ear seat, while making hydraulic support rotate 20 degree left and right; Then change the 3rd ear seat, while making hydraulic support move 40 degree left and right; Finally use winch pull rope to make hydraulic support withdraw 90-degree rotation on equipment, make it be easy to entrucking transport.
