Fig. 1 is a kind of signal for servicing unit that hydraulic support is assembled for underground that the utility model embodiment is provided Figure;
Fig. 2 is Fig. 1 left view.
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.
Embodiment
In order to make it easy to understand, the utility model will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, Fig. 1 is that a kind of underground that is used for that the utility model embodiment is provided assembles the auxiliary of hydraulic support The schematic diagram of device is helped, Fig. 2 is Fig. 1 left view.
A kind of servicing unit for assembling hydraulic support for underground that the utility model embodiment is provided includes base 6, lifted Part and bearing pin supporting parts 1 are risen, wherein, base 6 is provided with wheel;The bottom of lifting member is fixedly connected with base 6, the top of lifting member End can vertically be moved;Bearing pin supporting parts 1 and the top of lifting member are rotatably connected, and bearing pin supporting parts 1 are with respect to lifting member Rotated around vertical axis.
What the utility model was provided is used in the servicing unit that underground assembles hydraulic support, and base is provided with wheel, lifting The top of part 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 auxiliary Device has horizontal direction locomotive function, vertical direction lifting function and horizontal direction rotation adjustment function, can realize bearing pin The comprehensive action of assembling process, meets the assembling requirement of hydraulic support bearing pin.Because the servicing unit changes traditional people Bearing pin, the assembling mode of chain block lifting bearing pin are shouldered in work lift, so execute-in-place unsafe factor can be reduced effectively, are reduced The labor intensity of operating personnel, it is to avoid the unexpected injury of workmen.
In summary, the servicing unit that the utility model is provided can easily lifting heavy pin shaft, so as to improve underground Assemble 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 vertically moved, the top of jack 4 and the distance between base 6 are general 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.
