Description
(1) technical field
The utility model relates to a kind of colliery support apparatus---the dismounting equipment of oil cylinder in the hydraulic support, being a kind of wedge lock type working head that is suitable for being installed on the hydraulic cylinder dismantling machine that this case applicant separate case declares specifically, is a kind of Almightiness type special equipment that designs for dismounting bail type oil cylinder.
(2) background technology
China adopts hydraulic support to mine decades, the hydraulic prop equipment of introducing has nearly thousand covers, especially tear that equipment that cylinder uses is a kind of not to be had yet open and keep in repair used corollary equipment, what use in maintenance at present all is each homemade simple machine in mechanical repair plant, ore deposit, limited in one's ability, an equipment can only be torn a kind of oil cylinder of structure and specification open, and at present the specification of oil cylinder external diameter has kind more than ten, and each all will be made a working head and just can reach and tear whole oil cylinder series open.Zhengzhou factory once designed CMJ250 type of trial-production and tore the cap machine open in 92 years, its structural principle is two slotting pawl driving pawls, it is impartial in the ratchet endoporus that to make six square teeth corresponding with the dismounting groove of the fairlead of split oil cylinder, but the dismounting groove tolerance of fairlead and the deviation of position degree all are free tolerances, are difficult on the correspondence.While side's tooth internal diameter is very little with the gap, footpath, the end of guiding grooving, so the axiality that the center line of the center line of cylinder and working head requires is higher, seldom is concentric but the external diameter of cylinder is a blank with internal diameter.The another one factor is that afterbody is fixed oil cylinder, and the centre clamps again, and the axiality of skew can't be revised.Cause most of oil cylinder not enter working head for above-mentioned reasons, even enter working head, six teeth again can not be simultaneously stressed, has only 1～2 tooth stressed, and tooth can be pulled one by one when the resistance square was big.Shanxi factory also once designed tear a cylinder machine identical with above-mentioned principle, structure is respectively established an oil cylinder about being, piston rod head is adorned an angle iron, two angle irons are clamped oil cylinder, guarantee the axiality of oil cylinder and working head, but fairlead is coaxial with internal diameter, does not reach requirement with the external diameter axiality, and neither up and down can the adjustment, also can't satisfy and tear the cylinder needs open.More than the common issue with that exists of two kinds of products be: 1, the split oil cylinder overwhelming majority does not enter working head, can't realize tearing open the purpose of cylinder; 2, fix six square tooth unbalance stress, tooth is pulled one by one.3, a kind of working head can only be torn a kind of oil cylinder of structure and specification open.Can therefore, design a kind of cylinder machine of tearing open that satisfies multiple model specification oil cylinder, only the working head of tearing open on the cylinder machine head by replacing satisfies the needs of dismantling the different size oil cylinder, has caused relevant insider's concern.
(3) summary of the invention
The purpose of this utility model just at existing problem in the above-mentioned prior art and custom-designed a kind of be used to dismantle the bail type oil cylinder be suitable for being installed in wedge lock type working head on the hydraulic cylinder dismantling machine head, this working head is installed on the hydraulic cylinder dismantling machine that this case applicant separate case declares, can be specifically designed to dismounting bail type oil cylinder, change and use with " multijaw weighing apparatus power working head " that separate case is declared, can be helicitic texture and the different oil cylinder of cylinder diameter specification not only in order to dismounting cylinder mouth, also can be used for dismantling the cylinder mouth simultaneously for fixing, bail type structure and the different oil cylinder of cylinder diameter specification can satisfy the needs of dismantling different model specification oil cylinder.
The purpose of this utility model realizes by following scheme: the wedge lock type working head that originally is suitable for being installed on the hydraulic cylinder dismantling machine head comprises that its circumferential edge is along annular assembly that is evenly equipped with connection holes and the trimming body that is arranged in its ring, rectangle curved tooth by a plurality of mutual couplings between assembly and the trimming body is meshed, between a side field of conjugate action of each tooth, be provided with hemisphere, inner ring surface at trimming body offers three uniform curved surface grooves, three curved surface voussoirs are held in the mouth mutually by the curved surface groove on it and the flange of a pair of curved face type wedge lifting device that is installed in the trimming body both sides and are closed and can slide along wedge lifting device curved surface flange, be processed with teeth on the lower arcuate surface of curved surface voussoir, the shading ring that has the voussoir slot is installed on the side end face of trimming body, and the bottom of voussoir is inserted in the voussoir slot on the shading ring, anti-decylization is installed on the opposite side end face of trimming body, and voussoir promptly slides and then is raised or falls along wedge lifting device flange curved surface with the rotation of shading ring.
In the utility model, annular assembly is to be combined by two ring bodies; Be the sphere combination between assembly and the trimming body, be that mating surface is a sphere, and be meshed by four rectangle curved tooths that mate mutually between the two, between a side field of conjugate action of each tooth, be provided with hemisphere, hemisphere is arranged in the hemisphere nest that the curved tooth end face processes on the trimming body, makes its on-stream universal function with face contact.
This working head in use, at first combine by connection holes on the annular assembly and hydraulic cylinder dismantling machine head, tool using manually rotates shading ring, voussoir promptly slides and then is raised or falls along wedge lifting device flange curved surface with the rotation of shading ring, block the clip position of oil cylinder, and then tear the cylinder machine head open by rotation and drive the working head running, oil cylinder is dismantled.
Advantage of the present utility model is: aim at the design of bail type oil cylinder, cylinder mouth diameter is not limit, and rational in infrastructure, simple to operate, axiality is less demanding, and stressed even, applicability is wide, high efficiency.
