Description
Technical field
The utility model belongs to cold rolling mechanical equipment technical field, specifically relates to a kind of working roll power transmission shaft bracket system.
Background technology
In the cold rolling of strip steel process, for guaranteeing strip surface quality, need often change working roll, when the milling train of working roll transmission changes jobs roller, need the working roll power transmission shaft is held, so that extract working roll out replacing.Working roll power transmission shaft bracket system commonly used adopts bearing shell twin-screw adjusting device, need regulate bearing shell two ends screw rod respectively for holding up power transmission shaft when changing jobs roller, and complicated operation, required time are also longer.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of working roll power transmission shaft bracket system simple and compact for structure, convenient to operation is provided.
The technical scheme that provides according to the utility model: working roll power transmission shaft bracket system is characterized in that: comprise support, go up trailing arm, trailing arm, screw rod, bearing pin and handwheel down that last trailing arm, the middle part of trailing arm is cut with scissors with bearing pin respectively and is contained on the support down; The front end of last trailing arm, following trailing arm is used to hold the working roll power transmission shaft; Said support is provided with the last screw rod fixed head and following screw rod fixed head that is parallel to each other; Last screw rod fixed head is positioned at trailing arm top and parallel with the last trailing arm second half section; Following screw rod fixed head is positioned at trailing arm top and parallel with the following trailing arm second half section down; Last screw rod fixed head and following screw rod fixed head respectively are screwed with the screw rod of a rotatable turnover, and trailing arm, following trailing arm are pushed down in the screw rod lower end, and the screw rod upper end is equipped with handwheel through flat key.
As the further improvement of the utility model, said upward trailing arm, following trailing arm front end are equipped with backing plate, are concaved with the arc-shaped recess that adapts with working roll power transmission shaft shape on the backing plate.
As the further improvement of the utility model, the screw thread on the said screw rod adopts trapezoidal thread.
The utility model compared with prior art; Advantage is: the utility model is simple and compact for structure; Drive screw rod through handwheel and rotate, press down trailing arm, following trailing arm rear end through screw rod again, come rest working roll power transmission shaft according to lever principle; Convenient to operation, and the manufacturing cost of the utility model is also cheaper.

Description of reference numerals: 1-support, 1a-last screw rod fixed head, 1b-following screw rod fixed head, 2-following trailing arm, 3-screw rod, 4-bearing pin, 5-handwheel, 6-last trailing arm, 7-bearing pin, 8-split pin, 9-backing plate.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: said working roll power transmission shaft bracket system mainly is made up of support 1, time trailing arm 2, screw rod 3, bearing pin 4, handwheel 5, parts such as last trailing arm 6, bearing pin 7 and split pin 8.
As shown in Figure 1, last trailing arm 6, the middle part of trailing arm 2 is contained on the support 1 with bearing pin 7 hinges respectively down, and bearing pin 7 is through split pin 8 pinnings; Last trailing arm 6, the front end of trailing arm 2 is used to hold the working roll power transmission shaft down; Said support 1 is provided with the last screw rod fixed head 1a and following screw rod fixed head 1b that is parallel to each other; Last screw rod fixed head 1a was positioned at trailing arm 6 tops and parallel with last 6 second half sections of trailing arm; Following screw rod fixed head 1b is positioned at trailing arm 2 tops and parallel with following 2 second half sections of trailing arm down; Last screw rod fixed head 1a and following screw rod fixed head 1b respectively are screwed with the screw rod 3 of a rotatable turnover, and the screw thread on this screw rod 3 preferably is made as trapezoidal thread; Trailing arm 6, following trailing arm 2 are pushed down in screw rod 3 lower ends, and screw rod 3 upper ends are equipped with handwheel 5 through flat key 4, so that the turn of screw rod 3 is more laborsaving.
As shown in Figure 1, can stably hold the working roll power transmission shaft in order to make trailing arm 6, following trailing arm 2, said upward trailing arm 6, following trailing arm 2 front ends are equipped with backing plate 9, are concaved with the arc-shaped recess that adapts with working roll power transmission shaft shape on the backing plate 9.
During concrete the application; When needs change jobs roller; Rotation hand wheel 5, handwheel 5 drives screw rod 3 and moves downward, and screw rod 3 lower ends downward promote to go up trailing arm 6, following trailing arm 2; Last trailing arm 6, trailing arm 2 rotates around the bearing pin 7 of center respectively down, last trailing arm 6, descends the front end of trailing arm 2 to upwarp and hold respectively upper and lower working roll power transmission shaft.After roll change finishes; Opposite spin handwheel 5 makes screw rod 3 break away to go up trailing arm 6, trailing arm 2 down respectively, and last trailing arm 6, time trailing arm 2 are respectively around bearing pin 7 backward rotation of center; Last trailing arm 6, trailing arm 2 front ends leave upper and lower working roll power transmission shaft down, get final product operate as normal.
