Background technology
The mill speed of world today's cold-rolling mill and output develop towards high speed and serialization direction.The output of product depends on the mill speed of unit; the lumber recovery of band; the year maintenance of unit; the operating rate of downtime and unit etc.; in the shortening of downtime of unit, can improve and innovate; in downtime, mainly comprise the roll roll change; contingency is shut down; situations such as maintenance; working roll wherein; intermediate calender rolls roll change every day 4-6 time at least; whether can each roll change reach smoothly and realize that full-automatic fast roll changing is all having a strong impact on the length of roll changing time; directly affect product yield; in the milling train of design in the past; for various reasons; a lot of milling trains all can't be realized on-line automatic fast roll changing, all need manually intervention operation to finish roll change work.
The long stroke backup roll change of present known jobbing sheet-rolling mill, employing be that double sided rack drives the form that changing machine carries out roll change, this changing machine is in assembling and on-the-spot when roll change is installed, be difficult to guarantee that double sided rack locatees synchronously, adjust difficulty, waste time and energy, and needing tooth bar quantity many, cost is big.In order to address the above problem, those skilled in the art design a kind of changing rig that is driven by the unilateral gear rackwork, have avoided the synchronous difficult problem of double sided rack, yet it adopts single motor-driven mode to bring some drawbacks, big such as single motor investment, equipment is heavy; Just in case motor breaks down, changing machine can't move, and influences roll change efficient.
The utility model content
The utility model wants the technical solution problem to be: the changing rig motor synchronous and the gear stationary problem that overcome existing bilateral gear rack drives, a kind of fast roll changing push-and-pull vehicle device is provided, well solved drive motors and gear is synchronous, old roll can be pulled out from milling train by this push-and-pull vehicle device, new roll is pushed milling train finish automatic fast roll changing process, solve because roll changing time is long, directly affect the problem of product yield.
In order to solve above technical problem, a kind of fast roll changing push-and-pull vehicle device of the present utility model, its composition comprises: car body, clamp and drive unit thereof, bilateral driving motor, the bilateral gear that is driven by described driving motor, it is characterized in that: also have a frequency converter, the output of described frequency converter is connected with the bilateral driving motor, realizes that the bilateral driving motor rotates synchronously.
Two driving motors rotate by the gear that shaft coupling and power transmission shaft drive separately respectively, and tooth bar is fixed on roll change cart and the travelling platform car body, moves on tooth bar by gear, realizes moving forward and backward of push-and-pull vehicle car body.
The utility model adopts bi-motor transmission synchromesh gear respectively, has reduced the total capacity of motor greatly, has saved cost of investment; And two motors are realized making transmission more steady synchronously by frequency converter, and braking has accurately been avoided the impact of push-and-pull vehicle car body and roll shop building.
In addition, the utility model roll change push-and-pull vehicle device has four clamps of vertical setting, and two clamps constitute a pair of intermediate calender rolls clamp up and down, and middle two clamps constitute a pair of working roll clamp; Described clamp has two cursors, and balance staff and push-and-pull vehicle car body are fixed in the middle of it, and described clamp drive unit is a hydraulic cylinder, and the head of this hydraulic cylinder base, hydraulic cylinder push rod is rotationally connected with two cursor rear ends respectively.
Each clamp on the push-and-pull vehicle car body is by corresponding Driven by Hydraulic Cylinder, and after push-and-pull vehicle arrived assigned address and comes to a complete stop, the clamp hydraulic cylinder piston rod stretched out, and clamp is lived working roll, intermediate calender rolls roller head-clamp respectively.The motor-driven push-and-pull vehicle moves backward, and working roll, intermediate calender rolls are pulled out; After travelling platform was changed new roller, hydraulic clamp was clamped the roller head of new roller, and motor promotes push-and-pull vehicle and moves forward, working roll, intermediate calender rolls are inserted, after being in place, the withdrawal of clamp hydraulic cylinder piston rod, clamp is opened, and the push-and-pull vehicle car body can independently be return, and finishes the roll change action.The replacing of working roll, intermediate calender rolls can be carried out separately, saves roll changing time when helping fast roll changing, enhances productivity.
In order to prevent that car body from tumbling and axial motion takes place, the utility model car body both sides have the two rows directive wheel, on arrange directive wheel and be flat wheel, following row's directive wheel is a V shaped wheel.Flat wheel is used to prevent to tumble, and V shaped wheel is used to prevent that push-and-pull vehicle car body 1 from axial motion taking place.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model fast roll changing push-and-pull vehicle device front view.
Fig. 2 is the utility model fast roll changing push-and-pull vehicle device side view.
Fig. 3 is the utility model fast roll changing push-and-pull vehicle device vertical view.
The specific embodiment
The fast roll changing push-and-pull vehicle device of present embodiment, as Fig. 1, Fig. 2, shown in Figure 3, its composition comprises: car body 1, clamp 7,7 ', 8,8 ' and drive unit, bilateral driving motor 2,2 ', the bilateral gear 5,5 that drives by described driving motor ', its improvements are: also have a frequency converter (not drawing among the figure), the output of described frequency converter is connected with the bilateral driving motor, realizes that the bilateral driving motor rotates synchronously.The top of two driving motors 2,2 ' be positioned at push-and-pull vehicle car body 1 is also fixing with push-and-pull vehicle car body 1, synchromesh gear 5 (5 ') is in the below of driving motor 2 (2 '), connect by shaft coupling 3 and power transmission shaft 4 between driving motor 2 (2 ') and the synchromesh gear 5 (5 '), tooth bar 12,12 ' be fixed on the car body of roll change cart 11, driving motor 2 (2 ') rotates, synchromesh gear 5 (5 ') and tooth bar 12 (12 ') engagement, push-and-pull vehicle car body 1 moves forward and backward in roll change cart 11.
