Description
Technical field
The present invention relates to the special purpose device that anti-bearing block rotates, specifically refer to, in grinding roller operation area, when cleaning and installing bearing block, prevent the special purpose device that top chock rotates.
Background technology
Grinding roller operation area in iron and steel processing enterprise, cleans and installation shaft bearing is the indispensable operation procedure before roll operation.Fig. 4 is the structural representation of top chock, and under duty, two levers 7,8 that stretch out forward at the two ends, left and right of top chock are erected on guide rail; When disassembly, cleaning, top chock stretches out forward, is vacant state in-orbit on frame 5, and the centre of bearing block is the rotating shaft homalocephalus 6 stretching out, and in the situation that applying torque, between top chock and the rotating shaft of grinding roller, can relatively rotate.During the snap ring screw 9 of operative employee's dismounting bearing block root on lodging bench, must stand on the center between the lever of two, bearing block dead ahead.Nearly 700 kilograms of the weight of top chock, without External Force Acting in the situation that, top chock itself remains static and can not roll, once operative employee, the snap ring the turn of the screw of exerting oneself is installed, top chock has been applied to torque, and bearing block will be under very large effect of inertia and left-right rotation, and the head that two levers of bearing block will be got to operative employee causes security incident, in prior art, top chock is cleaned in dismounting needs two operators' cooperations to carry out.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of anti-bearing block to rotate special purpose device, when top chock is cleaned in dismounting, the homalocephalus of two levers of top chock both sides and rotating shaft can be fixed together, and prevents relatively rotating between the two.
The technical scheme that the present invention addresses the above problem is as follows:
Anti-bearing block rotates a special purpose device, it is characterized in that:
Comprise the crisscross fixer for holding rotating shaft homalocephalus, described crisscross fixer is by two affixed forming of door font metal frame, the top of the infall of described crisscross fixer is installed with lead screw, in described lead screw, be arranged with nut, the both sides of described nut are installed with left balancing pole and the right balancing pole on same straight line.
In use, as long as crisscross fixer is stuck in to rotating shaft homalocephalus, fastening nut, the balancing pole of nut both sides is placed on to the upper surface of two levers in left and right, relatively rotating between can preventing between rotating shaft homalocephalus and lever, guarantee that operating personnel, when the snap ring screw of dismounting bearing block root, avoid the generation of industrial accident.
As further improvement, this anti-bearing block rotates special purpose device and also comprises three bar hold down gags, described three bar hold down gags are fixed in swivel head by three and are mutually the depression bar of 120 ° and form, and described swivel head center is the circular hole of offering screw thread, and swivel head and lead screw are for being threaded.During use, this three bars hold down gag is sleeved in lead screw, firmly rotates three bar hold down gags, it is pressed on nut, nut is firmly fixing, thus guarantee that balancing pole is pressed on the upper end of two levers securely.Thereby safety coefficient is further increased, realize the double insurance of safety operation.
As preferred version, described nut-welding is in lead screw.In this case, nut and crisscross fixer and lead screw are as a whole.
The height of two door font metal frame is 20cm.This highly guarantees the firm of crisscross fixer and the combination of rotating shaft homalocephalus.
In sum, compared to the prior art, beneficial effect of the present invention is:
When using anti-bearing block of the present invention to rotate special purpose device, can the combination of top chock rotating shaft homalocephalus is as a whole, avoid relatively rotating between top chock rotating shaft homalocephalus, guaranteed operative employee's personal safety, the generation of the security incident of avoiding; In addition, only need an operative employee, just can complete dismounting cleaning, greatly improved the operating efficiency of cleaning and installation shaft bearing, reduced job costs.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail:
Embodiment 1
As shown in Figure 1, a kind of anti-bearing block rotates special purpose device, comprise the crisscross fixer 1 for holding rotating shaft homalocephalus, described crisscross fixer is by two door font metal frame 1a and 1b is affixed forms, the top of the infall of described crisscross fixer (i.e. the binding site of two door font metal frame) is installed with lead screw 2, the upper surface of lead screw and two door font metal frame is perpendicular, in described lead screw, be arranged with nut 3c, the both sides of described nut are installed with left balancing pole 3a and the right balancing pole 3b on same straight line.The height of two door font metal frame 1a, 1b is 20cm.
