Preferably, in above-mentioned servicing unit, the wheel is universal wheel.
It can be seen from above-mentioned technical proposal, provided by the present invention for underground assembling hydraulic support servicing unit in, bottom Seat is provided with wheel, and the top of lifting member can vertically move, and bearing pin supporting parts are rotated relative to lifting member around vertical axis, As can be seen here, the servicing unit has horizontal direction locomotive function, vertical direction lifting function and horizontal direction rotation adjustment work( Can, the comprehensive action of bearing pin assembling process can be realized, meet the assembling requirement of hydraulic support bearing pin.Due to the servicing unit Change traditional artificial lift and shoulder bearing pin, the assembling mode of chain block lifting bearing pin, it is possible to effectively reducing execute-in-place Unsafe factor, reduces the labour intensity of operating personnel, it is to avoid the unexpected injury of workmen.
In sum, the servicing unit that the present invention is provided can easily lifting heavy pin shaft, so as to improve underground assembling The operating efficiency of hydraulic support.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this Inventive embodiment, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis The accompanying drawing of offer obtains other accompanying drawings.
Fig. 1 is a kind of schematic diagram of servicing unit for underground assembling hydraulic support provided in an embodiment of the present invention;
Fig. 2 is the left view of Fig. 1.
Marked in figure:
1st, bearing pin supporting parts;2nd, swivel bearing;3rd, handrail is elapsed;4th, jack;5th, pedal;6th, base;7th, high intensity Universal wheel.
Specific embodiment
In order to make it easy to understand, the invention will be further described below in conjunction with the accompanying drawings.
It is that a kind of auxiliary for underground assembling hydraulic support provided in an embodiment of the present invention is filled referring to Fig. 1 and Fig. 2, Fig. 1 The schematic diagram put, Fig. 2 is the left view of Fig. 1.
A kind of servicing unit for underground assembling hydraulic support provided in an embodiment of the present invention includes base 6, lifting member With bearing pin supporting parts 1, wherein, base 6 is provided with wheel;The bottom of lifting member is fixedly connected with base 6, and the top of lifting member can Vertically move;Bearing pin supporting parts 1 are rotatably connected with the top of lifting member, and bearing pin supporting parts 1 are with respect to lifting member around perpendicular Straight axis are rotated.
In provided by the present invention for the servicing unit of underground assembling hydraulic support, base is provided with wheel, lifting member Top can vertically be moved, and bearing pin supporting parts 1 are rotated relative to lifting member around vertical axis, it can be seen that, the servicing unit With horizontal direction locomotive function, vertical direction lifting function and horizontal direction rotation adjustment function, can realize that bearing pin is assembled The comprehensive action of process, meets the assembling requirement of hydraulic support bearing pin.Because the servicing unit changes traditional artificial lift Bearing pin, the assembling mode of chain block lifting bearing pin are shouldered, it is possible to effectively reducing execute-in-place unsafe factor, operation is reduced The labour intensity of personnel, it is to avoid the unexpected injury of workmen.
In sum, the servicing unit that the present invention is provided can easily lifting heavy pin shaft, so as to improve underground assembling The operating efficiency of hydraulic support.
In specific practical application, lifting member can be jack, and wheel can be universal wheel, as shown in figure 1, the present embodiment In, jack 4 is arranged on base 6, and base 6 is provided with high intensity universal wheel 7.
Jack 4 is hydraulic jack, and is double telescopic oil cylinder type jack, and the mode of operation of jack 4 is foot-operated Formula, as shown in figure 1, jack 4 is provided with pedal 5.Certainly, in other embodiments, jack 4 can also be mechanical thousand Jin top.
In order to effectively lifting heavy pin shaft, the specified lifting weight of jack 4 is generally 500kg~700kg, and In the stroke for vertically moving, the top of jack 4 is general with the distance between base 6 in 855mm~1760mm models Enclose interior change.
Referring to Fig. 1, in order that bearing pin supporting parts 1 are easily rotated relative to lifting member, in the present embodiment, bearing pin supporting parts 1 with Swivel bearing 2 is provided between jack 4.
For the ease of support bearing pin, (can not marked in figure with setting horizontally extending draw-in groove on bearing pin supporting parts 1 Note).The cross section of draw-in groove can be circular arc or rectangle.In the present embodiment, bearing pin supporting parts 1 are by 10mm thick steel plate bending Into that is, draw-in groove is radiused cross-section, and in specific practical application, arc radius can be 50mm~80mm.
In the present embodiment, from the large scale square planar steel plate of 900mm × 1300mm, steel plate thickness is 10mm to base 6, And the bottom welding of base 6 has 5# channel-section steels as reinforcement, so that the rigidity of base 6 is effectively ensured.Install high in four angles end of base 6 Intensity universal wheel 7, high intensity universal wheel 7 carries blocking device (not shown), can be to high intensity in bearing pin assembling process Universal wheel 7 carries out secure ratcs, prevents vacillating for base 6, improves the stability of device.In order to reduce the center of gravity of base 6, improve The resistance to overturning of the servicing unit, the universal wheel of the preferred small-wheel-diameter of high intensity universal wheel 7.
As shown in figure 1, the passage of base 6 for convenience, can set passage handrail 3 on base 6.
During using the servicing unit, the heavy pin shaft for installing is needed first to be carried near support to be assembled hydraulic support, The servicing unit is pushed into by hydraulic support, behind the place of the adjustment position of base 6 to convenient working, high intensity universal wheel 7 is locked Only.Then, bearing pin is placed in the draw-in groove of bearing pin supporting parts 1, realizes that bearing pin is lifted by trampling the pedal 5 of jack 4 The adjustment of height, makes the angle of bearing pin be adjusted in lifting process, until pin by the effect of draw-in groove lower end swivel bearing 2 , be assembled into bearing pin in pin-and-hole finally by instruments such as sledgehammer or percussion hammers by axle alignment pin holes.
