Description
Technical field
The present invention relates to a kind of cold rolling tension roll more changing device, belong to cold rolling and safeguard equipment technical field.
Background technology
In cold rolling production, jockey pulley plays in whole production line as requisite equipment and provides tension force into strip steel
Effect.Jockey pulley is also referred to as S roller, is to utilize the friction between strip steel and jockey pulley to produce " winding effect " to obtain required
The tension force wanted.Jockey pulley in use for some time, is accomplished by the replacing of periodicity according to the abrasion condition of roll surface.For exposed
Replacing in Factory Building internal tension roller, it is only necessary to the assistance of overhead traveling crane just can complete.But in actual Production Line Configured, some
Power roller is arranged under operating room or in some semi-enclosed spaces, narrow space, it is impossible to use overhead traveling crane to be replaced.To this type of
The replacing of power roller, needs several operator to utilize multiple chain block, progressively moves jockey pulley, has bad luck and could will open
Power roller removal small space, mobile Renewal process is the most loaded down with trivial details, and wastes substantial amounts of manpower and materials, and impact produces joint normally
Play.
Summary of the invention
The technical problem to be solved is to provide a kind of cold rolling tension roll more changing device, can convenient, fast complete
The replacing of small space internal tension roller, time saving and energy saving.
The technical scheme solving above-mentioned technical problem is:
A kind of cold rolling tension roll changing rig, including horizontal support, roller seat, support means, leading screw and gear motor；
Described horizontal support includes that 2 are parallel to each other and track, flanged plate, locking side flange plate and at least 2 that length is equal
Cushion block, flanged plate, locking side flange plate are relatively fixed to two ends and and horizontal plane, 2 tracks, the flanged plates of 2 tracks
Forming the framework that a cross section is rectangular after fixing with locking side flange plate, the medial surface that 2 tracks are relative is fixed with mutually
2 parallel one slide rails；The bottom surface of each cushion block and 2 tracks is fixed；
Described roller seat include a surface plate, the roll stand being fixed on surface plate upper surface, be fixed on surface plate bottom surface contiguous block,
2 wheel shafts, 4 rollers being installed on 2 wheel shaft two ends that through contiguous block and are parallel to each other and be fixed on bottom contiguous block
Internal thread sleeve；Spacing between the roller at every wheel shaft two ends is identical with horizontal support 2 one slide rail gauge；4 rollers are located at horizontal stroke
On 2 slide rails being parallel to each other of support；Internal thread sleeve matches with leading screw, the axis of internal thread sleeve and flange in horizontal support
Plate, the locking line coincident in 2 flange hole centers of circle of side flange plate and vertical with axle axis；
Described support means is at least 2, and each support means is overall in " I shape ", fixes with spreader two ends including spreader
2 root posts and be installed on bottom 2 root posts support wheel；Described gear motor is fixed on 2 tracks by electric machine support
One end, motor shaft is connected with leading screw by shaft coupling, and leading screw passes through flanged plate flange hole, internal thread sleeve and locking side flange
The flange hole of plate.
Above-mentioned a kind of cold rolling tension roll changing rig, the cushion block of described horizontal support is 2 pieces, and the length of each cushion block is big
In the gauge of 2 tracks, 2 cushion blocks are individually fixed in the bottom surface at 2 track two ends and are parallel to each other, and the two ends of 2 cushion blocks are solid
Surely axis is had to be perpendicular to the slide cartridge of horizontal plane；The roll stand of described roller seat is at least 2 pieces of metallic plates being parallel to each other, metal sheet plane
With wheel shaft parallel and perpendicular to the surface plate of roller seat, the downward edge direction in metallic plate top has radius and matches with jockey pulley radius
Arc groove；The spreader upper surface of described support means is horizontal plane, and upper surface has the groove for placing jack；Horizontal
Column length is equal with the cushion block length of horizontal support；The shape of column, cross sectional dimensions respectively with cushion block two ends in horizontal support
Shape and the cross sectional dimensions of slide cartridge match, and the wheel shaft supporting wheel is vertical with the axis of spreader.
Above-mentioned a kind of cold rolling tension roll changing rig, the two ends of described leading screw are provided with axle sleeve, and on axle sleeve, sheathed band is convex
The sleeve of edge, sleeve flange has the through screw of through thickness of flange, the size of through screw and flanged plate in horizontal support
The size of connecting hole, the size of locking side flange plate connecting hole match；Leading screw end near gear motor is provided with pressing plate, pressure
Have the installing hole that thickness direction is through on plate, between leading screw end sleeve and the axle sleeve of gear motor, deep-groove ball is being installed
Bearing and thrust ball bearing, by realizing set through the bolt of installing hole, the through screw of sleeve and flanged plate connecting hole on pressing plate
Cylinder is connected with the fixing of flanged plate；Between sleeve and the axle sleeve away from the leading screw end of gear motor, thrust ball bearing is installed,

Step contacts until balancing each other with the gravity of jockey pulley with jockey pulley roll surface, now by the fixing disassembling bolts of jockey pulley both sides, to
Side away from jockey pulley pulls support means until the end face of jockey pulley detaches framework；Starter receiver driven by motor leading screw revolves
Turn, with coordinating of internal thread sleeve in roller seat, the rotary motion of leading screw is changed into the rectilinear movement of roller seat by leading screw, roller seat edge
The slide rail of horizontal support moves until behind the position that can lift by crane, stopping mobile, uses overhead traveling crane to be sling by the jockey pulley of replacing
Become the replacing of jockey pulley；New tension roller is installed can complete according to order contrary to the above.
The radial force that the present invention is produced by roller deadweight during using, and required for transverse shifting roller
Axial force, and the radial force that roller deadweight produces can be delivered on slide rail by roller seat.So screw mechanism is primarily subjected to axially
Power.Use thrust ball bearing and deep groove ball bearing with the use of, it is ensured that leading screw can bear the biggest axial load, and
Certain radial load can be born, simultaneously work as reducing the purpose of rotation friction.
The invention have the benefit that
The present invention is by horizontal support, roller seat, support means, gear motor and the cooperation of leading screw, it is not necessary to by manual calabash
The lifting devices such as reed can complete the three-dimensional direction moving of jockey pulley in small space, convenient, fast can complete small space
The replacing of internal tension roller, time saving and energy saving.
Present configuration is simple, easy to use, can produce roll dimension inspection field at metallurgy rolling and be applicable.
