Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
It is a kind of overhead traveling crane cylinder tool specially for attaching and detaching disclosed in the utility model, by arranging four cover positioners with axial power set are supporting, in whole dismounting and installation process, equal practical power set force cylinder to move axially on drum shaft, without the need to artificial dismounting, convenient operation, avoids damaging parts in manual operation process, improve overhaul efficiency, below by way of two specific embodiments, technical solutions of the utility model are described.
Embodiment 1: the present embodiment comprises axial power set, push rod, chuck, is fixedly mounted on four covers of chuck one side around the uniform positioner of chuck axis, described push rod is fixedly connected with the clutch end of axial power set, described chuck to be set on push rod and to be fixedly connected with axial power set, described often overlap positioner comprise tuning fork-like connector 8(see accompanying drawing 2) and metal hook 10(see accompanying drawing 3), described metal hook 10 tail end and tuning fork-like connector 8 front end hinged, described tuning fork-like connector 8 tail end is fixedly connected with chuck.In installation process, first the metal hook of four cover positioners is stuck in the locating hole of cylinder subplate, install hydraulic cylinder (also can adopt existing bearing dismantling machine) simultaneously, make its axis and drum shaft roughly coaxial, then start Hydraulic Cylinder push rod and move ahead, when behind push rod end and drum shaft ends contact, to the slow fuel feeding of hydraulic cylinder, the cylinder body of hydraulic cylinder moves backward, thus orders about cylinder outwards movement, until removed by cylinder by chuck and four cover positioners.
Described overhead traveling crane cylinder tool specially for attaching and detaching also comprises auxiliary retainer ring 1(for installation process see accompanying drawing 1), described auxiliary retainer ring 1 is symmetrical split-type structural, it comprises the identical semicircular ring of two nested structures, two ends of semicircular ring are equipped with contiguous block 2, two cover semicircular ring surround complete retainer ring, the radial location hole 5 be circumferentially provided with for wearing alignment pin 6 of described wherein a set of semicircular ring by means of the bolt through contiguous block 2; The yoke tail end of described tuning fork-like connector 8 is threaded in fixed disk; Described axial power set are hydraulic cylinder, and described push rod is coaxially fixedly connected with the piston rod of hydraulic cylinder, and described chuck is fixedly connected with hydraulic cylinder body.
In cylinder installation process, also need to implement by means of auxiliary retainer ring, first auxiliary retainer ring is fastened on cylinder end, and use bolt two semicircular ring to be locked, alignment pin is inserted in the hole on locating hole and cylinder simultaneously, realize axial location, then drum sleeve is contained on drum shaft, keyway is aimed at flat key, last fixer cylinder pressure, the metal hook of four cover positioners is hooked auxiliary retainer ring, primer fluid cylinder pressure pulls cylinder to move on drum shaft, until cylinder is in place simultaneously.
Embodiment 2: the difference of the present embodiment and embodiment 1 is axial power set, axial power set in the utility model are to make to produce axial relative motion between push rod and chuck, chuck is connected with cylinder by positioner, push rod top contacts with drum shaft, axial power set in the present embodiment are leading screw and mother lead screw combining structure, described push rod and leading screw end are coaxially fixed, described chuck is fixedly connected with mother lead screw, described leading screw tail end is provided with the handle for rotational lead screw, in embody rule process, pass through turning handle, leading screw is rotated, axial relative motion is produced between leading screw and mother lead screw, in motion process, leading screw itself only produces rotation, mother lead screw moves axially relative to leading screw, thus by chuck and four cover positioners, axial force is passed to cylinder, force rolling to produce relative to drum shaft to move axially, realize dismounting.
In a word, the utility model is by arranging four cover positioners with axial power set are supporting, in unloading process, four cover positioners can be utilized to be connected with cylinder by axial power set, under the effect of axial power set, cylinder is removed from drum shaft, in installation process, the supporting auxiliary retainer ring of positioner is overlapped with four, auxiliary retainer ring pinch roller end, after using four cover positioners to hook auxiliary retainer ring, axial power set are utilized to be contained on drum shaft by drum sleeve, in whole dismounting and installation process, equal practical power set force cylinder to move axially on drum shaft, without the need to artificial dismounting, convenient operation, avoid damaging parts in manual operation process, improve overhaul efficiency.
