Description

A kind of hydraulic cylinder dismantling machine

(1) technical field

The utility model relate to a kind of be used for to mining, particularly the colliery support apparatus---the hydraulic vertical prop (oil cylinder) of hydraulic support is dismantled the hydraulic cylinder dismantling machine of maintenance.

(2) background technology

China uses hydraulic support as the support apparatus in colliery decades, especially tear special equipment that cylinder uses open seldom 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.Once design CMJ250 type of trial-production in 92 years as Zhengzhou factory and tore the cap machine open, its structural principle is two slotting pawl driving pawls, dismounting groove in the ratchet endoporus on the impartial fairlead of making six square teeth and split oil cylinder is corresponding, 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.

(3) summary of the invention

The purpose of this utility model is just at existing problem in the above-mentioned prior art and custom-designed a kind of mining industry, particularly colliery support apparatus of being used for---the hydraulic vertical prop (oil cylinder) of hydraulic support is dismantled the hydraulic cylinder dismantling machine of maintenance.

The purpose of this utility model can realize by following technical proposals:

Hydraulic cylinder dismantling machine of the present utility model comprises frame, rack-mounted head, the working head that combines with head, and being arranged on aligning slide unit and the tailstock that is used to support split oil cylinder on the frame, described working head comprises that its periphery is evenly equipped with the toroidal shell of head connecting hole and is installed at least three pawl assemblies on the toroidal shell with equal mode for cloth; The connecting plate that described pawl assembly comprises the fixed connection shaft that is installed on the toroidal shell, combine with fixed connection shaft in mode movingly and by flexibly connecting the ratchet that axle combines with connecting plate and being arranged on back-moving spring above the ratchet side; The described two ends that flexibly connect axle are installed on and are positioned at the arc slot that processes on the annular guard board of the toroidal shell left and right sides; One side of ratchet is provided with the spacing block set that matches with the oblique limit guide groove that processes on the dial, and described dial is arranged between a ratchet and the side ring shape backplate.

Head described in the utility model comprises by the front and back bearings bearing and is installed in the ratchet-type final drive shaft of frame one end, the pawl type driving-disc that matches with the ratchet-type final drive shaft, and combine with engaging lug that place, pawl type driving-disc two edges is provided with about two hydraulic drive cylinders; Described pawl type driving-disc comprises with equal mode for cloth and is installed in three pawl assemblies on the toroidal shell; The connecting plate that described pawl assembly comprises the fixed connection shaft that is installed on the toroidal shell, combine with fixed connection shaft in mode movingly and by flexibly connecting the ratchet that axle combines with connecting plate and being arranged on back-moving spring above the ratchet side; The described two ends that flexibly connect axle are installed on and are positioned at the arc slot that processes on the annular guard board of the toroidal shell left and right sides.

The two ends why the utility model will flexibly connect axle are installed on and are positioned at the arc slot that processes on the annular guard board of the toroidal shell left and right sides, and be provided with the spacing block set that matches with the oblique limit guide groove that processes on the dial in the side of ratchet, its objective is in order to realize ratchet floating within the specific limits, be that ratchet can radially change, constitute instantaneous centre at random in the aligning scope on same circumference, to satisfy the dismounting of different cylinder diameter oil cylinders.

The release that the utility model is torn the cylinder machine open can make the operation of tearing this road difficulty of cylinder open realize the mechanization operation, not only can significantly increase work efficiency, and repair quality is guaranteed.Originally the working head of tearing open in the cylinder machine can exchange with " the wedge lock type working head " of applicant's separate case application of present patent application, can be helicitic texture and the different oil cylinder of cylinder diameter specification not only, also can be used for dismantling the cylinder mouth simultaneously and be fixing, bail type structure and the different oil cylinder of cylinder diameter specification in order to dismounting cylinder mouth.
