the roll changing trolley comprises a rotating shaft, wheels are respectively installed at two ends of the rotating shaft, the edges of the wheels, which are positioned on the inner side of the trolley guide rail, extend outwards to form convex edges, and the convex edges are used for keeping the moving direction of the roll changing trolley when the roll changing trolley moves along the trolley guide rail, so that the roll changing trolley is prevented from deviating.
Furthermore, a sleeve is arranged between the wheel and the rotating shaft.
Furthermore, an outer sleeve is sleeved on the rotating shaft and connected with a power output end of the air cylinder.
Further, the tool is a connecting rod, one end of the connecting rod is connected to the outer sleeve, and the other end of the connecting rod is connected to the working roller.
The utility model has the advantages that: the working roll is connected through roll change dolly one end, and the cylinder is connected to the other end, and the roll change dolly drives the working roll and removes the assigned position towards the assigned direction under the effect of cylinder to the moving direction of roll change dolly has been injectd through the dolly guide rail, and then avoids the working roll to run at the in-process of sideslip, and the accuracy nature of sideslip direction when having improved the change working roll has reduced the roll change time, has improved the productivity.
[ description of the drawings ]
FIG. 1 is a schematic structural view of a roll changing trolley suitable for changing a working roll of a strip steel four-high mill according to an embodiment of the application.
Wherein: 1. a work roll; 2. assembling; 3. a trolley guide rail; 4. a wheel; 5. a cylinder; 6. a sleeve.
[ detailed description ] embodiments
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The embodiment of the application provides a roll changing trolley suitable for changing a working roll of a strip steel four-roll mill, as shown in figure 1, the roll changing trolley comprises two trolley guide rails 3 which are paved on the inner sides of two tracks of the working roll and are arranged in parallel, the trolley guide rails 3 are provided with the roll changing trolley capable of moving back and forth along the trolley guide rails, the front end of the roll changing trolley is connected with a cylinder 5, the rear end of the roll changing trolley is connected with the working roll 1 to be installed through a tool 2, and the roll changing trolley is used for moving back and forth under the driving of the cylinder 5 so as to drive the working roll 1 to move to a specified.
The roll changing trolley comprises a rotating shaft, wheels 4 are respectively installed at two ends of the rotating shaft, the edges of the wheels 4, which are positioned at the inner sides of the trolley guide rails 4, extend outwards to form convex edges, and the convex edges are used for keeping the moving direction of the roll changing trolley when the roll changing trolley moves along the trolley guide rails 4 to prevent the roll changing trolley from deviating.
The working roll is connected through roll change dolly one end, and the cylinder is connected to the other end, and the roll change dolly drives the working roll and removes the assigned position towards the assigned direction under the effect of cylinder to the moving direction of roll change dolly has been injectd through the dolly guide rail, avoids the working roll to run at the in-process that removes. And the inner sides of the wheels are provided with convex edges, so that the wheels 4 can be prevented from deviating on a trolley guide rail, the accuracy of the moving direction of the replacement working roller is improved, the roller replacement time is reduced, and the productivity is improved.
In the embodiment of the application, a sleeve 6 is further arranged between the wheel 4 and the rotating shaft, and the rolling between the wheel 4 and the rotating shaft can be further increased through the sleeve 6, so that the wheel 4 and the rotating shaft are prevented from being rusted, and the wheel cannot roll on the trolley guide rail 3.
