Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency at above-mentioned existence, provide a kind of employing to flexibly connect, advantage with buffering shock-absorbing, improve the stability and the reliable transmission that connect shaft tray, the while also can reduce operative employee's workload and the chain shock absorbing type self-balancing of potential safety hazard connects shaft tray.
The technical scheme that its technical problem that solves the utility model adopts is:
Chain shock absorbing type self-balancing connects shaft tray, include and connect the shaft tray body, be installed in the support body that connects on the shaft tray body, slide block up and down is installed in the support body, slide block connects upward bottom spindle by connecing a gudgeon up and down, it is characterized in that: the described support body outside also is symmetrically installed with sprocket wheel and the chain that is overlapped on the sprocket wheel, the two ends of chain symmetry respectively connect top shoe and sliding block, and wherein, chain connects an end of sliding block, also be provided with tensioning apparatus, chain is connected with tensioning apparatus simultaneously.
In such scheme, described tensioning apparatus is installed in the outer process place of sliding block.
In such scheme, described tensioning apparatus includes spring pedestal and is installed in the interior spring of spring pedestal, has passed connecting rod in the middle of the spring, and the top of connecting rod is connected with chain.
In such scheme, described connecting rod bottom is processed with screw thread, and its bottom is installed on the spring pedestal by adjusting nut.
In such scheme, described adjusting nut is double nuts structure, realizes the adjusting to connecting rod on the one hand, can be fastenedly connected bar on the other hand.
Principle of the present utility model is that the abutment shaft carriage improves, the connecting rod of slide block changes chain into connecting up and down, and increase corresponding chain stretching device and spring shock-absorbing, give full play to chain and flexibly connect advantage with the spring shock-absorbing, the stability and the reliable transmission that connect shaft tray have been improved, also reduced simultaneously operative employee's workload and potential safety hazard, enhanced productivity.
The beneficial effect of the utility model device is:
1, go up the bottom spindle self-balancing, no matter be under any opening degree, the deadweight of last bottom spindle is mutual balance as system's internal force all the time, and both gravity is delivered to the support body that connects shaft tray by sprocket wheel together
2, employing flexibly connects, and has shock-absorbing effect, can regulate length automatically, need not artificial adjustment, reduces workload, eliminates safe hidden trouble, enhances productivity
3, it is convenient and swift that maintenance connects axle, and differential roller directly descends difference to connect an opening degree and need not manual adjustment, has saved a large amount of roll change non-cutting times, realizes fast roll changing, enhances productivity.
