Abstract
The invention discloses a compact working roll hoisting tool, which comprises a mount as a main body, two fixed tracks and a diplopore suite are respectively arranged on lower transverse plane of each end of the mount in vertical direction; a moveable rack is hoisted and arranged in a sliding mode on two fixed tracks through a roller mechanism, two working rolls are arranged on the moveable racks between two ends, levorotatory and dextrorotatory trapezoid nuts are arranged in the moveable rack in vertical direction; a transmission shaft and a leading screw respectively pass through an upper unthreaded hole and a lower unthreaded hole of two diplopore suites on a longitudinal direction, the transmission shaft and the leading screw enable driving connection through a driving gear and a driven gear; screw thread rotation direction of two ends of the leading screw is opposite, and the screw thread rotation direction of two ends of the leading screw is matched with screw thread of levorotatory and dextrorotatory trapezoid nuts. The compact working roll hoisting tool has the advantages of compact structure, safety, reliability, and simple operation.
Description
Technical field
The invention belongs to technical field of metallurgical equipment, relate to a kind of compact working roll lifting device.
Background technology
In band steel production process, owing to improving constantly the requirement of Product Precision and surface quality, production operational availability is high, and the use of breaker roll it is also proposed higher requirement, needs frequent breaker roll to carry out changing, care and maintenance.The roll changed, generally all needs to be lifted into the specific roll storage area of factory and carries out overhauling, safeguarding.
Generally adopt in two ways in hoisting process at present: one is lift with suspender belt or steel rope; Two is lift with special roller suspender.First kind of way needs workman to be fixed on the hanger of bearing seat by steel rope or suspender belt respectively in lifting process, and also will prevent steel rope in lifting process from breaking off relations, its poor stability, efficiency are low, and labour intensity is large.So present roll hoisting tool special is used widely in many large-scale steel mills, but very unreasonable in present roll hoisting tool special structure, and common lifting device easily hinders roll surface, and poor stability have impact on product design to a certain extent.
Summary of the invention
The object of this invention is to provide a kind of compact working roll lifting device, solve common lifting device and easily hinder roll surface, poor stability, efficiency is low, the problem that labour intensity is large.
The technical solution adopted in the present invention is, a kind of compact working roll lifting device, comprises the fixed mount as main body, is longitudinally separately installed with two trapped orbits and a diplopore external member in the lower surface that fixed mount is often held; Often hold two trapped orbits to pass downwardly through the slip of idler wheel mechanism correspondence and be lifted with a movable support body, be altogether provided with two working rolls up and down between the movable support body at two ends, in the movable support body at two ends, longitudinal correspondence is provided with the left and right trapezoidal nut revolved; Be installed with transmission shaft and leading screw respectively in the unthreaded hole up and down of two longitudinal diplopore external members, connected by principal and subordinate's gear transmission between transmission shaft and leading screw; The thread rotary orientation at leading screw two ends is contrary, and the thread rotary orientation at leading screw two ends mates with the left and right trapezoidal nut screw thread revolved.
Compact working roll lifting device of the present invention, is further characterized in that:
Fixed mount upper surface is provided with the hanger of lifting.
Transmission shaft one or both ends are coaxially connected with a handwheel.
The invention has the beneficial effects as follows, during work, turning handle can make movable support body open to both sides simultaneously, is convenient to working roll and loads; Rotate backward handle again after working roll places, movable support body moves inward, and breaker roll two end axles bearing is fixed, accurate positioning, and working roll uniform force is reasonable, does not hinder roll surface; During lifting, the Acme thread adopted due to this structure has auto-lock function, can prevent from loosening by actv., thus realizes safety lifting.Whole apparatus structure is compact, simple to operate, and efficiency is high, and safety is good, and applicability is strong, lifts by crane, also can lift the roll of differential roller footpath and different length the band a set of roll of bearing seat or one-tenth breaker roll.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present invention is, comprise the fixed mount 2 as main body, the hanger 3 (embodiment is four hangers 3) of lifting is installed in fixed mount 2 upper surface, is longitudinally separately installed with two trapped orbits 6 and a diplopore external member 12 in the lower surface that fixed mount 2 is often held; Often hold two trapped orbits 6 to pass downwardly through the slip of idler wheel mechanism 11 correspondence and be lifted with a movable support body 9, altogether be provided with two working rolls 10 up and down between the movable support body 9 at two ends, in the movable support body 9 at two ends, longitudinal correspondence is provided with the left and right trapezoidal nut 8 revolved; Transmission shaft 4 and leading screw 7 is installed with respectively in the unthreaded hole up and down of two longitudinal diplopore external members 12, be in transmission connection by principal and subordinate's gear 5 between transmission shaft 4 and leading screw 7, be coaxially connected with a handwheel 1 in transmission shaft 4 one or both ends, adopt manual rotation's transmission shaft 4 for either end; The thread rotary orientation at leading screw 7 two ends is contrary, the thread rotary orientation at leading screw 7 two ends mates with left and right trapezoidal nut 8 screw thread revolved, leading screw 7 two ends are threaded with the left and right trapezoidal nut 8 revolved, rotational lead screw 7 two ends left and right is revolved trapezoidal nut 8 and rotates simultaneously and realize opening and closing movement, so movable support body 9 is by the movement of idler wheel mechanism 11 on slide rail and trapezoidal nut 8 rotation direction control realization opening and closing movement.
Fig. 2 display be the right half part structure in apparatus of the present invention A-A cross section, Fig. 3 is integral structure of the present invention, apparatus of the present invention left-half structure and right half part full symmetric, omits and do not show in this Fig. 2.
The principle of work of apparatus of the present invention is,
Rotating handwheel 1 drives transmission shaft 4 to rotate, transmission shaft 4 is rotated by principal and subordinate's gear 5 turn-screw 7 of engagement pairing, because leading screw 7 can not move vertically, the revolving trapezoidal nut 8 and will move in or out simultaneously of leading screw 7 two ends, drive movable support body 9 on trapped orbit 6, utilize idler wheel mechanism 11 to move in or out simultaneously, realize the centering clamping of two movable support body in left and right, 9 pairs of working rolls 10 or separate, thus the working roll 10 that will lift by crane is placed and is fixed on lifting or dismounting in movable support body 9.
