Abstract
The utility model discloses a novel rolling mill dismounting tool, comprising a base. The top surface on one side of the base is vertically provided with a protective fence; the central part on one side of the base on the back of the protective fence is vertically provided with a rotating shaft. The top end of the rotating shaft is provided with a cantilever; two ends of the cantilever are respectively provided with a pulley; one end of a steel wire rope circling the two pulleys hangs a pneumatic wrench, an end portion of a rotating shaft of the pneumatic wrench being provided with a sleeve, and the other end of the steel wire rope is in connection with a balancing weight slidingly and cooperatively sleeved in the rotating shaft.
Description
Technical field
The utility model relates to a kind of professional tool for the large-scale operation of Steel-rolling Industry plant maintenance dismounting, particularly a kind of novel rolling mill dismantling device.
Background technology
At present, in Steel-rolling Industry, roll off the production line in roll change dismounting upkeep operation for chuck type mill, the artificial dismounting chuck of main employing, the instrument using is mainly box spanner, knocks the light instrument such as spanner and boosting-rod, in disassembly process, make operating personnel must make hammer knock or boosting-rod acts on spanner, expense just can be pulled down the bolt on milling train very energetically, the time-consuming effort again of operating process; In addition, what also have small part employing is the labor-saving tool such as pneumatic impact spanner and electric wrench, but in use tool operation process, operating personnel must have or lift heavy spanner cover upper bush in arms and operate, could remove and install operation to the bolt on milling train, similar pneumatic or electronic labour-saving spanner is first from great, adds the existence of reaction strength and shake in spanner work, cause using this type of labor-saving tool also to have drawback, make troubles to operating personnel.
Summary of the invention
The utility model proposes a kind of novel rolling mill dismantling device, it is simple in structure, easy to operate, can carry out dismounting to large-scale nut expeditiously, and it is time saving and energy saving to use.
The purpose of this utility model is to realize like this, a kind of novel rolling mill dismantling device, comprise base, on base one side end face, guard rail is vertically installed, base one middle side part at the guard rail back side is vertically installed with a rotating shaft, rotating shaft top has a cantilever, cantilever two ends are installed with respectively a pulley, pneumatic impact spanner is being hung in steel wire rope one end of walking around from two pulleys, the roller end of pneumatic impact spanner is installed with sleeve, and the other end of steel wire rope is connected with the balancing weight being sleeved in rotating shaft that is slidably matched.
When carry out dismounting maintenance use for the chuck type mill that rolls off the production line, first operating personnel are fixed on the milling train of required dismounting on special dismounting adapter on request, on pneumatic impact spanner, put the corresponding box spanner of wanting demounting bolt, operating personnel's both hands are caught pneumatic impact spanner, again by the steel wire rope on the pneumatic impact spanner hanging over, assembly pulley and be located at balancing weight effect hiding in swivel mount and easily pneumatic impact spanner promoted, the weight of balancing weight is equal in weight with pneumatic impact spanner, and the rotation swivel mount of taking advantage of a situation is placed in the bolt position place that need to dismantle milling train, aiming at bolt is sleeved on bolt the sleeve of pneumatic impact spanner completely, help on the other hand pneumatic impact spanner, manipulate on the other hand jettron, thereby complete the field-strip of chuck type mill large-sized bolt, realize simple to operateization of whole operation process, time saving and energy saving object.
By the above course of work, the use of this utility model milling train specific purpose tool makes in to large-sized bolt disassembly process, especially to the bolt disassembly operation of chuck type mill simplified operating process, labor intensity of operating staff is reduced greatly, save corresponding equipment dismounting maintenance time, improved operating efficiency.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
