the utility model is achieved through the following technical solutions: portable lifting appliance, the base that comprises two skid shoe types placed side by side, four pillar stiffeners, two roll shafts, the bracing frame of rectangle, each pillar stiffener is all by an end opening, the upper sleeve pipe of one end sealing and case in consist of, upper sleeve pipe is connected with cased closed end, and be respectively installed with jack and lower jack in upper sleeve pipe and case in, the piston rod of upper jack and lower jack stretches out respectively sleeve pipe and cased opening, the piston rod that four lower jacks stretch out vertically is fixed on respectively the end of two base upper surfaces, be fixed with respectively the pipe link that is positioned at directly over base between two case on same base, two roll shafts lay respectively between the case in of two bases with end, and roll shaft one end is articulated on the case in of a side, other end bolt is connected on the case in of opposite side, on described roll shaft, kink has long roller, the two ends of long roller are provided with symmetrically along the outward extending spacing preiection of circumference, four upper jacks stretch out piston rod upper end is fixed on respectively four bights of bracing frame, the bracing frame downside two piece track girders parallel with roll shaft that suspend, two track girders are provided with can be along the actuated small roadster of track girder walking, the bracing frame downside that is positioned at two track girders outsides suspends respectively and controls front jack and the rear jack of actuated small roadster opposite sense motion each other, and described actuated small roadster downside suspention has jack.
During concrete the use, lifting appliance described in the utility model is equipped with controls the flexible hydraulic efficiency pressure system of each jack, and the BRW-125/31.5 emulsion power pack that described hydraulic efficiency pressure system can rely on fully-mechanized mining working to use provides pressure for it.
Before concrete the use, the long roller of lifting appliance described in the utility model is across on track, and stop bit has guaranteed that lifting appliance can not derail when mobile between two spacing preiections of long roller.Manually promote lifting appliance or drive lifting appliance by winch to move in orbit.
During concrete the use, at first lifting appliance is passed to predetermined operating location, and hydraulic efficiency pressure system is communicated with by joint with the liquid in-out pipeline of emulsion power pack, and U-shaped pin fixes joint.Locking lifting appliance: open emulsion power pack, open respectively the control cock of upper jack and lower jack, the piston rod of upper jack and lower jack stretches out, bracing frame rises to and holds out against back, base drops to the compression roadway floor, long roller de-orbits, and has guaranteed the steady and safety of this device.
Then, specifically use work flow as follows:
A. dumping apron task program
1. dismantle the bolt of roll shaft one side end, will move to side with the roll shaft of long roller, the vehicle that chute is housed stops after vehicle comes to a complete stop, in time having set the double track stop device at direction of fall to the bracing frame below, then roll shaft is resetted, and tightens the bolt of end;
2. start jack, the chute on vehicle is worked section by section winching to proper height;
3. the control cock of jack or rear jack before opening, before utilizing, jack or rear jack are passed assigned address to dumping apron with actuated small roadster, utilize jack that the chute of slinging is transferred;
4. actuated small roadster is retracted into reference position;
5. repeat 2. above-mentioned～4. step, until the chute on this vehicle is unsnatched;
6. dismantle the bolt of the roll shaft end of opposite side, empty wagons is left.
B. unload elevating conveyor, broken carbon device parts task program: identical with the task program of dumping apron.
At last, if during mobile lifting appliance, start emulsion power pack, upper jack and lower jack are retracted, bracing frame is retracted to the upper bush top, base is retracted to the base upper side and holds out against the lower sleeve end face, and long roller is across on track, utilizes manually promote lifting appliance or by winch, lifting appliance pushed to next operating location.
Lifting appliance described in the utility model has changed the mode of operation that in the past manually pulls the jack lifting, and is easy to operate, improved work efficiency, reduced workman's labour intensity, and its lock function actv. prevents the in use movement of lifting appliance.Lifting appliance described in the utility model the job interviews such as Wang Zhuan colliery 52/2# driving surface, 43B2,61B1 with in, unloading is aimed in chute, elevating conveyor parts, broken carbon device parts operation, has greatly reduced employment quantity and labour intensity; The front and rear part the middle pan of scraper conveyor is to when dress, and is more convenient to operate, quick, compares with orthodox method, and work efficiency is enhanced about more than once; Simultaneously, use workman's number from before 5 people reduce to 2 people, every bottom class save 3 artificial, have long-range economic benefit and social benefit.
