Abstract
The invention relates to mining equipment, in particular to a movable type hoisting device, solving the problem that heavy equipment is difficult to mount in the working conditions without hoisting equipment, such as underground coal mine. The movable type hoisting device comprises two piston shoe type base seats which are arranged in parallel, four supporting columns, two roller shafts and a rectangular supporting frame. According to the movable type hoisting device, the operation way of hoisting by manually pulling a chain block is changed, the operation is convenient, the working efficiency is improved, the labor intensity of workers is reduced, and the hoisting device is effectively prevented from moving by a locking function when in use. During trial of the hoisting device in working faces such as 52/2#, 43B2 and 61B1 in Wangzhuang coal mine, and in the operations of dismantling and aligning chutes, reversed loader components and carbon breaker components, the hoisting device has the functions of greatly reducing the number of workers and labor intensity; when middle grooves of front and back scraper conveyors are butted, the hoisting device is convenient to operate quickly; compared with the traditional method, the working efficiency is improved by more than one time; and the hoisting machine has long-term economic and social benefits.
Description
Technical field
The present invention relates to a kind of mining equipment, specifically a kind of at the inferior service conditions downward moving lifting appliance without weight-lifting equipment of coal mine.
Background technology
Along with the development of combining the technology of adopting, fully-mechanized mining equipment is to heavy-duty, high-performance future development.Therefore, the weight of equipment also increases greatly, and the installation of fully-mechanized mining working has also been caused certain difficulty, has increased workman's labour intensity.
The example that is installed as with slat conveyer, in the installation process of traditional fully-mechanized mining working, the workman needs will load in advance the flat truck haul of the middle pan of scraper conveyor to cutting on the track of eye middle part, jack is installed in the place of erection, artificial pulling jack unloads chute from flat truck after, use an other cover jack that chute is pulled to the installation site, manually adjust direction, install.The whole dependence of whole process are manually carried out, and labour intensity is large, and required personnel are many, production time is longer, also have certain potential safety hazard in operation process.
In sum, be necessary to design a kind of mining mobile lifting appliance.
Summary of the invention
The present invention provides a kind of flexibly portable lifting appliance in order to solve heavier equipment installation hard problem under the inferior service conditions without weight-lifting equipment of coal mine.
The present invention is achieved by 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 all is by an end opening, the upper sleeve pipe of one end sealing and case in consist of, upper sleeve pipe links to each other with cased closed end, and be respectively installed with jack and lower jack in upper sleeve pipe and the 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 the base between two case on the 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, and kink has long roller on the described roll shaft, and the two ends of long roller are provided with symmetrically along the outward extending spacing preiection of circumference; The piston rod upper end that jack stretches out on four 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 girder outsides suspends respectively and controls front jack and the rear jack of each other opposite sense motion of actuated small roadster, and described actuated small roadster downside suspention has jack.
During concrete the use, lifting appliance of the present invention is equipped with the flexible hydraulic efficiency pressure system of each jack of control, 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 of the present invention is across on the track, and stop bit has guaranteed that lifting appliance can not derail when mobile between two spacing preiections of long roller.The artificial lifting appliance or mobile in orbit by winch drive lifting appliance that promotes.
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 the vehicle is worked section by section winching to proper height;
3. the control cock of jack or rear jack before opening, jack or rear jack are passed assigned address to dumping apron with actuated small roadster before utilizing, and 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 the track, utilizes manually to promote lifting appliance or by winch lifting appliance is pushed to next operating location.
Lifting appliance of the present invention has changed the mode of operation that in the past manually spurs 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 of the present invention is in the job interviews such as Wang Zhuan colliery 52/2# driving surface, 43B2,61B1 are used, and unloading is aimed in chute, elevating conveyor parts, the 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.
