Description
Technical field
The present invention relates to the isolated plant that anti-bearing block rotates, specifically refer to, in the grinding roller operation area, clean and when installing bearing block, prevent the isolated plant that top chock rotates.
Background technology
Grinding roller operation area in iron and steel processing enterprise is cleaned and the installation shaft bearing is the front indispensable operation procedure of 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 on rail frame 5, and the centre of bearing block is the rotating shaft homalocephalus 6 that stretches out, in the situation that apply torque, can relatively rotate between the rotating shaft of top chock and grinding roller.During the snap ring screw 9 of operative employee's dismounting bearing block root on lodging bench, must stand in the center between the lever of bearing block two, dead ahead.Nearly 700 kilograms of the weight of top chock, in the situation that without External Force Acting, top chock itself remains static and can not roll, in case the operative employee installs snap ring when exerting oneself the turn of the screw, top chock has been applied 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 the 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 isolated plant, when top chock is cleaned in dismounting, two levers of top chock both sides and the homalocephalus of rotating shaft can be fixed together, relatively rotating between preventing both.
The technical scheme that the present invention addresses the above problem is as follows:
A kind of anti-bearing block rotates isolated plant, 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, be arranged with nut on described lead screw, the both sides of described nut are installed with left balancing pole and the right balancing pole that is on same straight line.
In use, as long as crisscross fixer is stuck in the rotating shaft homalocephalus, fastening nut, the balancing pole of nut both sides is placed on the upper surface of two levers in left and right, relatively rotating between 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, should also comprise three bar hold down gags by anti-bearing block rotation isolated plant, 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 on 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 on 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 isolated plant, 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 the 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:
As shown in Figure 1, a kind of anti-bearing block rotates isolated plant, 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, be arranged with nut 3c on described lead screw, the both sides of described nut are installed with left balancing pole 3a and the right balancing pole 3b that is on same straight line.The height of two door font metal frame 1a, 1b is 20cm.
In use, as long as crisscross fixer is stuck in the rotating shaft homalocephalus, fastening nut, the balancing pole of nut both sides is placed on the upper surface of two levers in left and right, at this moment relatively rotating between can preventing between rotating shaft homalocephalus and lever, be placed on the rail frame in the crescent (not shown) position with the rotating shaft homalocephalus and fix, guarantee that operating personnel when the snap ring screw of dismounting bearing block root, avoid the generation of industrial accident.
Embodiment 2
