Background technology
Heat treatment furnace is the important equipment in steel plate heat treatment process, and heat treatment furnace can be divided into according to purposes difference
Normalizing furnace, glowing furnace, tempering furnace etc., these stoves are mainly used to steel plate heating, heat preservation, cooling, steel plate by normalizing, return
Fire, quenching, to improve the mechanical performance of steel plate.
The width and length of above-mentioned heat treatment furnace are larger, and there is chamber furnace thorax, furnace bottom to be made of furnace roller and transmission mechanism,
Transmission mechanism is mounted on outside burner hearth, is rotated by furnace roller and is sent into steel plate or workpiece by feed end, discharge end is sent out outside stove.Stove
Interior mounted roller subnumber amount is more, and in-furnace temperature is up to 600 DEG C -- and 950 DEG C or so, by the movement of steel plate or workpiece on furnace rolls,
Realize technological requirement.
Above-mentioned heat-treatment furnace is in addition to there are steel plate inlet and outlet at both ends, and entire furnace body is at closed state, due to being used under high temperature
Frequently, the roller in stove by high temperature in the case where being carried motion state, frequent occurrence the defects of roller bending, bulge, pockmark, burr,
These defects on roller generate harmful effect to the surface quality of steel plate or workpiece, for this purpose, at regular intervals will blowing out
Maintenance, replaces the serious roller of defect.Currently, replacing furnace rolls, due to there is no specific purpose tool, relies only on overhead traveling crane and match
Roll change is closed, it is time-consuming and laborious, increase maintenance and replaces workload.
Utility model content
The utility model aim is to provide a kind of roller hearth heat-treated furnace roll change follow-up trolley, can facilitate at roller-bottom type heat
The replacement for managing the roller in stove, solves the problems, such as background technology.
The technical solution of the utility model is：
A kind of roller hearth heat-treated furnace roll change follow-up trolley, including leading screw, screw, suspension hook, vehicle frame and wheel, the vehicle frame
Including support plate and support leg, four support legs are fixed below support plate, are all provided with below each support leg there are one wheel,
Screw is fixed on the supporting plate, and leading screw passes through support plate, leading screw to be threadedly coupled with screw, and leading screw is arranged vertically with support plate, silk
The lower end of thick stick is equipped with suspension hook.
The screw is fixed on the center of support plate, and the center of support plate is equipped with and the matched hole of leading screw.
The upper end of the leading screw is square structure.
It is equipped with reinforcing rib between support plate and support leg in the vehicle frame, lacing wire is equipped between two support legs.
Using the utility model, the furnace rolls period of the day from 11 p.m. to 1 a.m is replaced, trolley is placed on furnace rolls road, the Partner of close furnace roller,
Wheel is replaced an intermediate roller, roller is covered with steel wire rope and is hung on suspension hook, roller using two rollers as track
The fixed seat at both ends is dismantled, rotating threaded shaft, and roller Partner is mentioned, and removes the bearing of Partner, is then led to outside stove
Cross the cooperation of crane, so that it may to realize the quick-replaceable of roller in hot stove.
The utility model has the beneficial effects that：The replacement of the roller in roller hearth heat-treated furnace can be facilitated, it is simple in structure,
Securely and reliably.

Specific implementation mode
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
With reference to attached drawing 1,2, a kind of roller hearth heat-treated furnace roll change follow-up trolley, including leading screw 2, screw 3, suspension hook 4, vehicle frame
5 and wheel 6, the vehicle frame 5 includes support plate 5-1 and support leg 5-2, and four support leg 5-2 are fixed below support plate 5-1,
It being all provided with there are one wheel 6 below each support leg 5-2, screw 3 is fixed on support plate 5-1, and leading screw 2 passes through support plate 5-1,
Leading screw 2 is threadedly coupled with screw 3, and leading screw 2 is arranged vertically with support plate 5-1, and the lower end of leading screw 2 is equipped with suspension hook 4.
In the present embodiment, the processing and making process of roller hearth heat-treated furnace roll change follow-up trolley is as follows：
The steel plate that one piece of thickness of cutting is 25 millimeters or so, 450 millimeters of square of size, as the support plate 5-1 of vehicle frame 5,
One circular hole of heartcut, pore size can pass through leading screw 2 to be advisable, and leading screw 2 is spun on screw 3, and leading screw 2 penetrates support plate 5-1
Hole in after screw 3 is welded on support plate 5-1；
Four support leg 5-2 are welded in quadrangle below support plate 5-1 with angle steel, and the angle of inclination of support leg 5-2 will use up
It measures identical, one group of rotary wheel 6 is filled below each support leg 5-2, wheel shaft and support leg 5-2 weld together.Two
An angle steel is welded between a support leg 5-2 as lacing wire 5-4, uses angle steel as reinforcement between support leg 5-2 and support plate 5-1
Muscle 5-3 is welded, and plays a part of to increase intensity.When welding installation, the centre-to-centre spacing size of two wheels 6 will be equal to phase in stove
Adjacent hearth roll installation center away from 2 times.
A upper rotary suspension hook 4 is welded in the lower end of leading screw 2, suspension hook 4 can make 360 ° of rotations.
The detailed process for replacing furnace rolls is as follows：
1. the asbestos thermal insulation material at roller both ends roller neck of dismantling, trolley is placed on furnace rolls road, close to the quilt of furnace roller
Moved end, wheel 6 are replaced an intermediate roller, roller are covered extension with shorter steel wire rope using two rollers as track
On suspension hook 4, the roller fixed seat at roller both ends is dismantled, the square handle on 2 top of rotating threaded shaft makes leading screw 2 move up, steel wire
Rope is slowly tightened up, and then proceedes to rotating threaded shaft 2 and roller Partner is mentioned, and height is moderate, removes Partner
Bearing；
2. with crane in stove fit on, with steel cable, one end bolt the drive end of roller outside stove, and steel cable is another
End is hung on the hook of crane, then slowly lifts hook, roller drive end is made to raise, it is high by 10 millimeters -60 to leave branch seat stand
Millimeter or so, along the direction for roller being pulled out stove, the trolley of the trolley of traveling hoist, the other end hangs roller with shifting
It is dynamic, the lifting by crane and mobile mutual cooperation, when the body of roll is pulled out about half length or so, rotating threaded shaft 2,
Steel wire rope is unclamped, lower roller is unloaded.The steel cable that the crane bolt of the roller other end also unclamps, at this moment, the intermediate load of entire roller
On the foundation base of roller drive end installation site, with steel cable again pulled out half roller bolt it is good, utilize crane
Entire roller is hung outside stove.When installing new roller, process is opposite.
