Description
Technical field
Mine cage hoisting catching device is the utility model is related to, more particularly to a kind of new type mining pressure tank balance cage chair.
Background technology
At present, China is mainly having three kinds with mine cage chair：One kind is common cage chair, with counterweight, by coaster impeller-hub
On crank lifting, the operating mechanism of cage chair is the form disengaged, therebetween without fixed connection, when hydraulic cylinder piston rod stretching
When, promote coaster to be swung up crank, and ensure that what rocking arm can stablize be in lifting status, when hydraulic cylinder piston rod retraction
When, rocking arm is voluntarily fallen, and the guide rail lining that point is overlapped on cage edge is shaken in front end, and this structure is mainly characterized by cage chair and is overlapped on
After on cage edge, when cage is lifted because of the change steel wire rope of load generation elastic deformation, rocking arm can be without hindrance with cage
The swing hindered, defect are to carry clump weight, and operating mechanism is fragile, and occupied space is big below cage chair, and construction and installation are difficult, especially
Easily slide down when being big part under deep-well.Second is steady tank cage chair, eliminates counterweight, has installed steady tank beam additional, oil cylinder is arranged at lower part
Driving lifting, defect is to utilize the steady tank of cage chair, cage chair fragile bearing block after being hit, and cage normally has the corner cage guide steady
Tank, for oil cylinder in lower part, long-time cylinder rod is stretched outside outside, fragile.The third is support (lock) tank cage chair, with catching device,
Complicated, for drive cylinder all in lower section, space for maintenance is small, and cylinder rod is stretched outside outside for a long time, fragile.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of new type mining pressure tank balance cage chair, the cage chair structure
Simply, it is easy to use, and maintenance is convenient and efficient, extends the service life of oil cylinder.
To achieve the above object, the utility model provides following technical solution：A kind of new type mining pressure tank balance cage chair,
Including cage chair body, the cage chair body is installed on pit shaft side, and cage chair body includes cage chair bearing plate and held for cage chair
The swing span that fishplate bar is swung, is also installed with fixed frame on the pit shaft side, and a pair of of oil is installed with the fixed frame
Cylinder fixed beam, is lifted with oil cylinder in the oil cylinder fixed beam respectively, the telescopic rod of oil cylinder downward, the cage chair bearing plate
Both sides are hinged by the telescopic rod of articulation piece and two oil cylinders respectively.
Preferably, the both sides of cage chair bearing plate are welded with cage chair tie-beam, are respectively welded on the cage chair tie-beam
Lifting lug I, lifting lug I are hinged with the telescopic rod of oil cylinder respectively.
Preferably, two oil cylinder fixed beams are connected by lifting lug II with the base of oil cylinder respectively.
Preferably, cage chair bearing plate is welded with the pressing member for pushing down cage close to one end of pit shaft.
Using above-mentioned technical proposal, the utility model compared with prior art, has the advantages that：1. oil cylinder is installed
On the top, replacement convenient to overhaul, and the telescopic rod most of the time contracting of oil cylinder, in oil cylinder, service life is grown；2. under cage chair
Fang Buzai needs space, eliminates civilwork engineering quantity.3. normal operation and lower big part are separately treated, ensure that the stop time does not prolong
It is long.4. be suitable for deep-well, there are enough adjusting strokes, when lower big part can eliminate steel wire rope elastic elongation, securely and reliably.5. knot
Structure is simple, easy to use.
Brief description of the drawings
Fig. 1 is state diagram when the utility model cage chair bearing plate pushes；
Fig. 2 is state diagram when the utility model cage chair bearing plate lifts.
Embodiment
Below in conjunction with the accompanying drawings, by the description of the embodiment, being described further to the utility model：
As shown in Figure 1, 2, a kind of new type mining pressure tank balance cage chair of the utility model, including cage chair body 1, cage chair body
1 is installed on pit shaft side, and cage chair body 1 includes cage chair bearing plate 11 and the swing span 12 swung for cage chair bearing plate 11,
Fixed frame is also installed with pit shaft side, a pair of of oil cylinder fixed beam 2 is installed with fixed frame, is divided in oil cylinder fixed beam 2
Oil cylinder 3 is not lifted with, and two oil cylinder fixed beams 2 are connected by lifting lug II, 6 with the base of oil cylinder 3 respectively, the telescopic rod of oil cylinder 3
Downward, the both sides of cage chair bearing plate 11 are hinged by the telescopic rod of articulation piece and two oil cylinders 3 respectively, and articulation piece is used and hung
Ear I 5.The both sides of cage chair bearing plate 11 are welded with cage chair tie-beam 4, and lifting lug I, 5 is respectively welded on cage chair tie-beam 4, is hung
I, 5 telescopic rod respectively with oil cylinder 3 of ear is hinged.Cage chair bearing plate 11 is welded with for pushing down cage 8 close to one end of pit shaft
Pressing member 7.
The utility model is in normal operation, and in the lower part connected pipes of oil cylinder 3, top connects threeway control or opens wide, tank
Cage 8 in place after, the dead weight oil return of cage chair body 1 is leaned in 3 lower part of oil cylinder, and cage chair bearing plate 11 falls.Object moves on to cage chair bearing plate
After 11,3 lower part of oil cylinder is oil-filled, and oil cylinder 3 lifts simultaneously self-locking in place.Down during big part, also connected pipes, cage 8 arrive on the top of oil cylinder 3
Behind position, 3 top of oil cylinder is oil-filled, and lower part oil return, cage chair bearing plate 11 continues to pressurize after falling, and the pressure of cage 8 is held, works as cage chair
Bearing plate 11 can be with loading-unloading vehicle after reaching setting value to the pressure of cage 8.Since oil cylinder 3 indirectly can produce pressure to cage 8
Power, steady during so as to ensure big part disengaging tank, after big part entrucking, 3 lower part of oil cylinder is oil-filled, and top oil return, oil cylinder 3 is lifted
Play simultaneously self-locking in place.
The utility model compared with prior art, has the advantages that：1. oil cylinder 3 is mounted above, convenient to overhaul
Replace, and the telescopic rod most of the time of oil cylinder 3 contracts in oil cylinder 3, service life length；2. the lower section of cage chair no longer needs sky
Between, eliminate civilwork engineering quantity.3. normal operation and lower big part are separately treated, ensure that the stop time does not extend.4. suitable for deep
Well, there is enough adjusting strokes, and when lower big part can eliminate steel wire rope elastic elongation, securely and reliably.5. simple in structure, user
Just.
Above-described is only the preferred embodiment of the utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
