Abstract
The utility model discloses a straightening machine presss from both sides tight first jack catch resetting means, the support frame made including ring shape steel sheet, around the three sets of hydraulic jack and the manual oil pump of support frame axis of rotation equipartition, manual oil pump oil -out through three high -pressure rubber pipes respectively with three sets of hydraulic jack's oil pocket intercommunication, install quick change coupler between high pressure fuel pipe and the hydraulic jack, three sets of jack are all radially installed and the revolving axle of tailpiece of the piston rod portion towards the support frame, install three sets of hydraulic jack on the support frame as pressure device through the use to use three sets of hydraulic jack of manual oil pump synchronous operation, the hydraulic jack of three sets of synchronization can slowly radially push down the jack catch, makes it reset under the prerequisite of not damaging the jack catch, and is easy and simple to handle, improves the operating efficiency.
Description
Technical field
The utility model relates to straightener repairing auxiliary device technical field, particularly relates to a kind of straightener clamping head claw resetting means.
Background technology
Heavy section steel dual-gripper straightener adopts automatic changing rig, before automatic roll change each straightening shaft clamping head on after claw automatic retraction for fixing smoothing roll roller shell, just automatic roll change can be carried out, due to former changing rig design defect, major part claw can not normally be retracted, axle sleeve cannot be unclamped, the hammer radial direction that needs manually to put on airs knocks claw, make it set back, unloading process labour intensity is very big, and safety coefficient is lower, be easy to claw is out of shape, claw is caused to damage, sometimes new chuck jaw can only be changed, have a strong impact on roll change efficiency, improve spare parts cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of straightener clamping head claw resetting means, be arranged on three on bracing frame by use and overlap hydraulic jack as pressure apparatus, and use hand oil pump simultaneously operating three to overlap hydraulic jack, the synchronous hydraulic jack of three covers slowly radial direction can press down claw, under the prerequisite not damaging claw, make it reset, easy and simple to handle, improve operating efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of straightener clamping head claw resetting means, comprise bracing frame that annular steel plate makes, hand oil pump and around the uniform three cover hydraulic jack of bracing frame axis of rotation, described hand oil pump oil-out is communicated with three oil pockets overlapping hydraulic jack respectively by three high-pressure rubber pipes, between high-pressure rubber pipe and hydraulic jack, hydraulic quick coupler is installed, described three cover hydraulic jack are all radial install and piston rod end towards the gyroaxis of bracing frame.
The bracing frame outer rim that described annular steel plate is made is offered the hole for hoist for lifting.
Bracing frame one side that described annular steel plate is made is provided with three around the uniform groove of its axis, and three grooves are all radial to be arranged, and described hydraulic jack is installed in groove.
The beneficial effect that produces of technique scheme is adopted to be: to overlap radial hydraulic jack of installing by the supporting installation three of bracing frame made from annular steel plate, the piston rod of hydraulic jack is towards the axis of rotation direction of bracing frame, position is identical with the claw regularity of distribution on clamping head, when needs press down claw, with overhead traveling crane, this device is sling, and be mounted opposite in clamping head, three cover hydraulic jack are corresponding three cover claws respectively, three cover hydraulic jack are synchronously driven by operation hand oil pump, inwardly extrude claw simultaneously, make it reset, easy and simple to handle, structure is simple, can it be made to reset under the prerequisite not damaging claw, reduce spare parts cost and labour intensity, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state schematic diagram of the present utility model;
Wherein: 1, bracing frame; 2, hydraulic jack; 3, hand oil pump; 4, high-pressure rubber pipe; 5, hydraulic quick coupler; 6, claw; 7, clamping head.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1, the utility model discloses a kind of straightener clamping head claw resetting means, comprise bracing frame 1 that annular steel plate makes, hand oil pump 3 and around the uniform three cover hydraulic jack 2 of bracing frame 1 axis of rotation, described hand oil pump 3 oil-out is communicated with three oil pockets overlapping hydraulic jack 2 respectively by three high-pressure rubber pipes 4, hydraulic quick coupler 5 is installed between high-pressure rubber pipe and hydraulic jack 2, described three cover hydraulic jack are all radial install and piston rod end towards the gyroaxis of bracing frame 1; Bracing frame 1 outer rim that described annular steel plate is made is offered the hole for hoist for lifting; Bracing frame 1 one side that described annular steel plate is made is provided with three around the uniform groove of its axis, and three grooves are all radial to be arranged, and described hydraulic jack 2 is installed in groove.
In embody rule process, the utility model overlaps radial hydraulic jack of installing by the supporting installation three of bracing frame made from annular steel plate, the piston rod of hydraulic jack is towards the axis of rotation direction of bracing frame, position is identical with the claw regularity of distribution on clamping head, when needs press down claw, with overhead traveling crane, this device is sling, and be mounted opposite in clamping head, three cover hydraulic jack are corresponding three cover claws respectively, three cover hydraulic jack are synchronously driven by operation hand oil pump, inwardly extrude claw simultaneously, make it reset, easy and simple to handle, structure is simple, can it be made to reset under the prerequisite not damaging claw, reduce spare parts cost and labour intensity, improve operating efficiency, conveniently carry out automatic roll change.
