Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figures 1 to 3, cold-rolling mill roll assembling device, comprises the V-type frame 1 for placing roll 18, is arranged at the track 2 of V-type frame both sides, and is arranged on track and for the dismounting chassis of dismounting roll chock; Described dismounting chassis comprises the vertical shift dolly 3 being arranged on track, be arranged at the cross traveling trolley 4 on vertical shift dolly, be arranged at the hydraulic cylinder 5 moving on vertical shift dolly and for controlling cross traveling trolley, be arranged at the lifting platform 6 on cross traveling trolley, and be arranged at the lift 7 that rises or fall for controlling lifting platform on cross traveling trolley.
In order to ensure the stable of roll, and roller surface is not damaged, and described V-type frame upper surface is provided with the first pad 8 directly contacting with roll, and lifting platform upper surface is provided with the second pad 9 directly contacting with roll chock.
In order to adjust accurately the height of lifting platform, and can guarantee the dynamics that lifting platform contacts with bearing block, described lift comprises the screw-threaded shaft elevator 19 being connected with lifting platform, and be connected by power transmission shaft 20 with screw-threaded shaft elevator and for controlling the handwheel 10 of screw-threaded shaft elevator, this power transmission shaft is fixed on cross traveling trolley by bearing block 21.
The phenomenon of tumbling when preventing lifting platform supporting bearing base gravity, on described vertical shift dolly, be also provided with and be " the anti-tipping bearing 11 of [" type, cross traveling trolley below is provided with coupled connecting rod 12, and the lower end of this connecting rod is provided with the anti-tipping little axle 13 that can snap in anti-tipping bearing.Owing to being provided with anti-tipping little axle below cross traveling trolley, in the time that needs support bearing block, this anti-tipping little axle can be along with the movement of cross traveling trolley is carried out in anti-tipping bearing, be stuck, cross traveling trolley just can not be tumbled like this, namely tilt to both sides, guaranteed whole process safety.
