Description
Technical field
The utility model relates to the pin removal in the occasion that is applied in coal mine hydraulic supporting disintegration process and needs dismounting hinging pin shaft.
Background technology
In the colliery of pit mining, be subjected to auxiliary shaft diameter and cage transport capacity, comprise the restriction of height and width dimensions, hydraulic support need be disintegrated is that base and back timber two parts could be transported input well smoothly.Conventional hydraulic support disintegration process needs manually the central pin shaft of articulated roof beam and base to be extracted, and base and back timber could be separated.Method is: three people stand on the platform of a 2m * 1.5m * 1.2m and carry out the write off operation in the mode of manually drawing hammer; Extract a bearing pin and expend 1-2 hour, as when running into special circumstances such as bearing pin corrosion, back timber and caving shield dislocation, construction intensity and difficulty are just bigger.Because construction space quality narrow and small, bearing pin reaches more than 25 kilograms, labour intensity is big, causes worker's mental fatigue easily, safety problem occurs.Therefore, no matter be from secure context, still consider from the aspect of increasing work efficiency, all must find out a kind of instrument that can carry out the hydraulic support disintegration safely, fast.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of hydraulic support automatic pin removal, separate body running so that hydraulic support can be carried out effectively, improve the safety guarantee that hydraulic support is separated body running, effectively reduce workman's hydraulic support disintegration labour intensity, increase work efficiency.
The utility model technical solution problem adopts following technical scheme:
The design feature of the automatic pin removal of the utility model hydraulic support is: a pin removal girder that can be placed on the back timber of hydraulic support is set, form with the two ends symmetry on described pin removal girder fixedly installs brace summer by junction plate in the mode of welding, and fixedly installs hydraulic cylinder on the hydraulic cylinder leg that is made of brace summer and junction plate; Described hydraulic cylinder is connected with emulsification pump by control valve; Described hydraulic cylinder is connected to a fixed by connecting rod and back timber pin.
The design feature of the automatic pin removal of the utility model hydraulic support also is: described hydraulic cylinder is to be connected by dismountable connecting pin with connecting rod, and described back timber pin adopts threaded engagement to be connected with connecting rod.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model material therefor is conventional material, and common machine making factory can design processing;
2, the utility model operation and maintenance is all very easy, and common pincers worker just can very well be safeguarded and troubleshooting;
3, the utility model can increase work efficiency, shorten the construction period, with Ding Ji ore deposit 1141 (3) work plane installation processes is example, need 117 hydraulic supports that disintegrate altogether, every hydraulic support need be extracted two bearing pins, and 117 hydraulic supports need be extracted 234 bearing pins altogether; If according to the disassembling method of routine, a work team two hydraulic supports that can only disintegrate at most, the disintegration cycle of 117 supports is 20 days; And utilizing the utility model examination operation, five hydraulic supports that disintegrate can be accomplished the task satisfactorily in eight days; Efficient has improved 60%, has shortened the construction period greatly.
4, the utility model has reduced labour intensity very effectively, and the worker only need operate the valve group of the automatic pin removal of hydraulic support, just can smoothly bearing pin be extracted, and has reduced labour intensity.The bearing pin of choosing in the conventional hydraulic support disintegration process needs at least three people carry out coordinative construction, utilize the utility model then 2 bearing pins only need 2-3 people to get final product complete operation, manually saved 50%.
5, the utility model safety, economic benefit obviously embody, owing to adopt the automatic pin removal construction of hydraulic support, the operating personnel only needs the outbreak of remote-controlled operation hydraulic pressure that the automatic pin removal of hydraulic support is controlled, and it is big that the construction safety space becomes, and has eliminated the potential safety hazard of routine work.In the disintegration process of Ding Ji colliery 1141 (3) work plane ZZ8800 type hydraulic supports, an accident does not take place, artificial saving 50%, duration shortens 60%, save 2 artificial calculating according to each bottom class, 300 yuans of calculating in a man-hour, only cost of labor is one, and the automatic pin removal of hydraulic support is just saved and about 172800 yuan for the Ding Ji colliery.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
Referring to Fig. 1, in the present embodiment, the one pin removal girder 1 that can be placed on the back timber of hydraulic support 10 is set, form with the two ends symmetry on pin removal girder 1 fixedly installs brace summer 4 by junction plate 2 in the mode of welding, on the hydraulic cylinder leg that constitutes by brace summer 4 and junction plate 2, fixedly install hydraulic cylinder 3, the concrete model of hydraulic cylinder is extracted the required power of hinging pin shaft according to measuring and calculating and is chosen, and the power that needs is big more, and the diameter of cylinder of selected hydraulic cylinder is big more; Hydraulic cylinder 3 is connected with emulsification pump by control valve, and connecting the high-pressure rubber pipe voltage withstand class that adopts must not be less than 25Mpa; The tailpiece of the piston rod of hydraulic cylinder 3 is to be connected to a fixed by connecting rod 7 and back timber pin 6.
In concrete the enforcement, the tailpiece of the piston rod of hydraulic cylinder 3 is to be connected by dismountable connecting pin 9 with connecting rod 7, and back timber pin 6 adopts threaded engagement to be connected with connecting rod 7.Back timber pin 6 has been provided with screw when dispatching from the factory, back timber pin 6 is the hydraulic support back timber of needs dismounting and the hinging pin shaft of base; During work, 3 actions of manually-operated control valve control hydraulic cylinder utilize hydraulic cylinder 3 flexible strength to extract the hydraulic support hinging pin shaft.
During use, at first the pin removal in the present embodiment is hung on the hydraulic support back timber of waiting to disintegrate, and tangles hoisting ring 5 with the protection rope with lifting appliance, as the main rope of lifting in the construction operation by one reserve safety precautions after breaking; With lifting appliance the back timber of the hydraulic support 10 of waiting to disintegrate is hung flatly then, and be close to pin removal girder 1; Block the back timber of the hydraulic support 10 of waiting to disintegrate with limited block 8, to guarantee stress equalization in the disintegration process;
With high-voltage tube the hydraulic cylinder on the pin removal 3 is connected with emulsification pump with the control valve of supporting setting again and puts in place; It is good hydraulic cylinder 3 usefulness connecting pins 9 to be fixedlyed connected with connecting rod 7 again, again connecting rod 7 is connected with back timber pin 6, after connection finishes, open emulsification pump power is provided, manipulation valve group makes hydraulic cylinder 3 actions, utilize the strength of hydraulic cylinder 3 action to pull out, take off back timber pin 6 as the back timber pin 6 of hydraulic support hinging pin shaft.
Because hydraulic support weight is big, lifts by crane used wire rope or anchor chain, must guarantee to lift by crane safety in conjunction with the disrumpent feelings coefficient of the accurate calculating of back timber, base weight of hydraulic support.
If the operation bearing pin than difficult situation of taking out, can be taked the method for continuous several times repetitive operation; When adopting above-mentioned way still can't take out, can change two hydraulic cylinders 3 of symmetry simultaneously, use the bigger cylinder body of cylinder diameter to carry out operation as actuating mechanism.
