Description
Technical field
The invention belongs to technical field of metallurgical equipment, relate to a kind of compact working roll slinger
Tool.
Background technology
In strip steel production process, owing to the requirement of Product Precision and surface quality is constantly carried
Height, production operational availability is high, and the use to roll it is also proposed higher requirement, and it is the most right to need
Roll is replaced, care and maintenance.The roll changed, is typically necessary and is lifted into work
Factory's specific roll storage area carries out overhauling, safeguarding.
Two ways is typically used at present: one is to carry out with suspender belt or steel wire rope in hoisting process
Lifting；Two is to lift with special roller suspender.First kind of way needs during lifting
Steel wire rope or suspender belt are fixed on the hanger of bearing block by workman respectively, also to prevent from lifting by crane
In journey, steel wire rope breaks off relations, and its poor stability, efficiency are low, and labor intensity is big.So, roll now
Roller hoisting tool special is used widely in many large-scale steel mills, but roll Special-purpose hanger now
In holding tool structure the most unreasonable, common lifting device easily hinders roll surface, poor stability, certain journey
Product quality is have impact on degree.
Summary of the invention
It is an object of the invention to provide a kind of compact working roll lifting device, solve common lifting
Instrument easily hinders roll surface, poor stability, and efficiency is low, the problem that labor intensity is big.
The technical solution adopted in the present invention is, a kind of compact working roll lifting device, including
As the fixed mount of main body, longitudinally it is separately installed with two in the lower surface that fixed mount is often held and fixes
Track and a diplopore external member；Often two trapped orbits of end pass downwardly through the slip of idler wheel mechanism correspondence
It is lifted with a movable support body, between the movable support body at two ends, is the most altogether provided with two work
Roller, in the movable support body at two ends, longitudinal correspondence is provided with the trapezoidal nut of left and right rotation；Longitudinal
The unthreaded hole up and down of two diplopore external members is installed with respectively power transmission shaft and leading screw, power transmission shaft and leading screw it
Between connected by principal and subordinate's gear drive；The thread rotary orientation at leading screw two ends is contrary, the spiral shell at leading screw two ends
Stricture of vagina rotation direction is mated with the trapezoidal nut screw thread of left and right rotation.
The 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.
Power 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 simultaneously to two
While open, it is simple to working roll loads；Working roll rotates backward handle, movable stand after placing again
Body moves inward, and will be fixed roll two end axles bearing, accurate positioning, working roll stress
The most rationally, roll surface is not hindered；During lifting, the trapezoidal thread used due to this structure has certainly
Lock function, can effectively prevent from loosening, thus realize safe lifting.Whole apparatus structure is compact,
Simple to operate, efficiency is high, and safety is good, and the suitability is strong, roll a set of to band bearing block or one-tenth
Roll is lifted by crane, also the roll in differential roller footpath and different length can be lifted.

Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
With reference to Fig. 1, Fig. 2, Fig. 3, the structure of the present invention is, including fixing as main body
Frame 2, be provided with in fixed mount 2 upper surface lifting hanger 3 (embodiment is four hangers
3), it is separately installed with two trapped orbits 6 and one in the lower surface longitudinal direction that fixed mount 2 is often held
Diplopore external member 12；Often hold two trapped orbits 6 to pass downwardly through corresponding slip of idler wheel mechanism 11 to hang
Equipped with a movable support body 9, between the movable support body 9 at two ends, the most altogether it is provided with two works
Making roller 10, in the movable support body 9 at two ends, longitudinal correspondence is provided with the trapezoidal nut 8 of left and right rotation；
The unthreaded hole up and down of two longitudinal diplopore external members 12 is installed with power transmission shaft 4 and leading screw 7 respectively,
Be in transmission connection by principal and subordinate's gear 5 between power transmission shaft 4 and leading screw 7, in power transmission shaft 4 one end or
Two ends are coaxially connected with a handwheel 1, use manual rotation's power transmission shaft 4 for either end；Silk
The thread rotary orientation at thick stick 7 two ends is contrary, and the thread rotary orientation at leading screw 7 two ends is trapezoidal with left and right rotation
Nut 8 screw thread mates, and threadeds with the trapezoidal nut 8 of left and right rotation in leading screw 7 two ends, turns
The left and right rotation trapezoidal nut 8 at movable wire thick stick 7 then two ends rotates simultaneously and realizes opening and closing movement, so
Movable support body 9 passes through the idler wheel mechanism 11 movement on slide rail and trapezoidal nut 8 rotation direction controls
Realize opening and closing movement.
Fig. 2 is shown that the right half part structure of apparatus of the present invention Section A-A, and Fig. 3 is this
The overall structure of invention, apparatus of the present invention left-half structure is full symmetric with right half part,
This Fig. 2 omits not display.
The operation principle of apparatus of the present invention is,
Rotating handwheel 1 drives power transmission shaft 4 to rotate, principal and subordinate's tooth that power transmission shaft 4 is matched by engagement
Take turns 5 turn-screws 7 to rotate, owing to leading screw 7 can not be axially moveable, the rotation at leading screw 7 two ends
Trapezoidal nut 8 will move in or out simultaneously, drives movable support body 9 at trapped orbit 6
On utilize idler wheel mechanism 11 to move in or out simultaneously, it is achieved two, left and right movable support body 9
Centering to working roll 10 clamps or separates, thus the working roll 10 that will lift by crane is placed and consolidates
It is scheduled in movable support body 9 and lifts by crane or dismantle.
