Abstract
The utility model discloses a multiplication stroke push-and-pull device which is used for pushing in or pulling out the working roll system for rough rolling and precision rolling main mill working roll replacing in the cold and hot rolling plate blank production line of large steel companies. The device comprises a base, a support and a hydraulic cylinder, and is characterized by also comprising a push rod, a gear, a fixed rack and a movable rack, wherein the hydraulic cylinder is hinged on the support which is fixedly installed on the base; the lever of the hydraulic cylinder is hinged on a pin roll and supported on the track through supporting wheels II at two sides of the pin roll; the gear is supported on the pin roll through a bearing and respectively meshed with a rack I and a rack II; the rack I is fixedly installed on the base, and the rack II are fixedly installed on the push rod; the push rod is positioned through the supporting wheel I installed on the base and side guide wheels installed on the base at two sides thereof; a push-pull hook is installed on the push rod; and the hydraulic cylinder pushes the push rod to push in and pull out the working roll. The device can lead the stroke of the hydraulic cylinder to have multiplication effect, thus leading the equipment structure to be compact.
Description
Technical field
The utility model relates to a kind of times of journey push-pull device at fixed, is used for the hot-rolled and cold-rolled slab production line roughing of iron and steel corporation and the device that pushes and pull out working roll system that finish rolling main mill working roll is changed.
Background technology
At present, work roll changing all adopts automatic changing rig in the slab four roller hot-rolled and cold-rolled units both domestic and external, changing rig is made up of Traverse Displacement Unit and push-pull device at fixed two parts, it is the centering framework window that Traverse Displacement Unit is responsible for working roll, and push-pull device at fixed is responsible for working roll system is pushed and pull out framework window.The body of work parts of push-pull device at fixed generally drive with big stroke push-and-pull hydraulic cylinder or electric trailer.Because of being subjected to the restriction of push-and-pull stroke and piston rod rigidity and guiding difficulty and precision, general in order to reach required stroke, adopt the form of twin-tub series connection, this big stroke hydraulic push-pull device at fixed can be applied on 2800mm and the following specification mill roll machine thereof, and the big stroke milling train of the above specification of 2800mm, the general electric trailer device that adopts drives, its shortcoming is that structure and control thereof are complicated, poor stability, and driving force is little, control accuracy is low, deficiency in economic performance.
Summary of the invention
The present invention seeks to push and pull out the shortcoming and defect that working roll is a device for what improve that existing operation roll of mill changes, a kind of times of journey push-pull device at fixed proposed, the utility model adopts the Driven by Hydraulic Cylinder working gear to drive tooth bar promotion push rod and finishes the roll change process, makes the stroke of hydraulic cylinder produce times Cheng Xiaoying; Thereby make compact equipment, occupy little space and have energy savings, investment cost is low, reliable operation.
Technical solution of the present utility model is achieved in that
A kind of times of journey push-pull device at fixed comprises support, support and hydraulic cylinder, it is characterized in that: also comprise push rod, gear, stationary rack and movable tooth bar, described hydraulic cylinder is hinged on the support, and support is fixedly mounted on the support; The hydraulic cylinder lever is hinged on the bearing pin, the hydraulic cylinder lever is supported in orbit by the support wheel II that is installed in the bearing pin both sides, gear by bearings on bearing pin, gear meshes with tooth bar I and tooth bar II respectively, tooth bar I is fixedly mounted on the support, and tooth bar II is fixedly mounted on the push rod, and push rod is located by the side guide wheel that is installed in the support wheel I on the support and be installed on its both sides support, the push-and-pull hook is installed on the push rod, and hydraulic cylinder promotes push rod working roll is advanced and pulls out.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model adopts the Driven by Hydraulic Cylinder working gear to drive tooth bar promotion push rod and finishes the roll change process, use pinion and rack that hydraulic cylinder travel is amplified to 2 times, the same specification milling train adopts this kind structure push-and-pull cylinder stroke can be narrowed down to original 1/2 and gets final product.Equipment weight reducing effect is obvious;
2, the utility model has solved the root problem of the above work roll changing machine of 2800mm specification.Adopt the rack-and-pinion serial mechanism can also realize 4 times, 8 times, 16 times in addition ... times Cheng Xiaoguo.This device also can be applied on other similar devices, and extending space and the promotional value of better practicality and Geng Gao promptly arranged;
3, the utility model compact conformation, hydraulic cylinder manufacture difficulty and manufacturing cost also decline to a great extent, and better operability, controlled and ease for maintenance are arranged, and simultaneously, Hydraulic Station capacity and unit interval supply capability also have tangible reduction effect, save cost.
