Abstract
The utility model relates to a synchronous servo lifting device which at least comprises an upper slide block, a lower slide block, a roller way, a screw rod, a balance shaft, a servo trolley, a slide rail and a pull rod seat. The synchronous servo lifting device is characterized in that the lower slide block and the slide rail are respectively fixed on a base seat of a rack and a base seat of the slide rail, the upper slide block and the lower slide block are connected in a sliding mode, and the pull rod seat, the roller way and the upper slide block are in rigid connection through bolts. One end of the balance shaft is fixedly connected with the pull rod seat, and the other end of the balance shaft is connected with the servo trolley in a sliding mode. One end of the screw rod is connected with the pull rod seat in a thrust bearing mode, the other end of the screw rod is connected with the servo trolley through the screw rod, and the servo trolley is connected with the slide rail in a rolling mode. By means of rotation of the screw rod, the upper slide block and the lower slide block can slide, so that synchronous servo lifting device can play a role of adjusting the height of the roller way, and achieves the height adjustment of the roller rail with relatively large load. The synchronous servo lifting device is mainly applied to cold reducing mill roller way lifting.
Description
Technical field
The utility model is applied to the cold pilger mill roller-lifting, is a kind of synchronous follow-up lowering or hoisting gear.
Background technology
The general span of tubing specification that a lot of cold pilger mills are contained is all very big, and shell when nipping centering require very highly, therefore want the tubing of rolling different size, roller-way must be through going up and down adjust the center.A lot of original roller-liftings are regulated through ramp blocks, pull bar pulling ramp, and pull bar is through feed screw nut's pulling, between them through being articulated and connected.Find in the practical operation when the adjustment height, the angle between pull bar and the screw mandrel hour, more or less freely adjusting; In case yet the change of the adjustable height on inclined-plane is big, it is big that the angle between pull bar and the screw mandrel becomes, and the adjusting of screw mandrel becomes very difficult even transfers motionless; Reason just is that the angle of screw mandrel and pull bar becomes big; The horizontal component that acts on the pull bar is then more and more littler, so need a kind of novel structure to realize the synchronous adjustment of screw mandrel and pull bar, reduces even eliminates the angle between them; To reduce the loss of power ability, the efficient when increasing work.
The utility model content
The purpose of the utility model is: design a kind of synchronous follow-up lowering or hoisting gear, be used for adjusting the height of roller-way, give with the pipe that adapts to different size.It is mainly used in the cold pilger mill roller-lifting.
The purpose of the utility model realizes through following technical scheme: a kind of synchronous follow-up lowering or hoisting gear is characterized in that: which comprises at least top shoe, sliding block, roller-way, screw mandrel, trunnion shaft, servo-actuated dolly, slideway, draw-bar seat; Sliding block and slideway are individually fixed on stand base and the slideway base; Be slidingly connected between top shoe and the sliding block, be rigidly connected through bolt between draw-bar seat and roller-way, the top shoe, trunnion shaft one end is fixedly connected with draw-bar seat; The other end and servo-actuated dolly are slidingly connected; Screw mandrel one end becomes thrust bearing to be connected with draw-bar seat, and the other end is connected through screw mandrel with the servo-actuated dolly, and the servo-actuated dolly rolls with slideway and is connected.
Described top shoe and sliding block be shaped as right angled triangle, angle is the angle that can satisfy self-locking between top shoe and the sliding block, the hypotenuse of two slide blocks is a contact edge, can slide along hypotenuse.
Described servo-actuated dolly can be along the slideway scroll-up/down.
The beneficial effect of the utility model is:
1, can adjust roller-way effect just thereby play so that slide between the slide down piece through rotary screw, realize the adjustment of the height of the roller-way of load greatly.
2, can roller-way comparatively accurately be adjusted at needed height, and have good self-locking performance.
3, the adjustment required torque is constant and less.
4, have the good free degree, do not have stuck phenomenon.
5, have good autgmentability, and finally can realize the automatically accurate adjustment function of whole stand height through electrical control.

The specific embodiment
Embodiment 1
As shown in Figure 1: a kind of synchronous follow-up lowering or hoisting gear which comprises at least top shoe 2, sliding block 3, roller-way 4, screw mandrel 6, trunnion shaft 8, servo-actuated dolly 9, slideway 10, draw-bar seat 13; It is characterized in that: sliding block 2 is individually fixed on stand base 1 and the slideway base 5 with slideway 10, is slidingly connected between top shoe 2 and the sliding block 3, is rigidly connected through bolt between draw-bar seat 13 and roller-way 4, the top shoe 2; Trunnion shaft 8 one ends are fixedly connected with draw-bar seat 13; The other end and servo-actuated dolly 9 are slidingly connected, and screw mandrel 6 one ends and draw-bar seat 13 the inner thrust ball bearing 11 and bearing block 12 are installed for thrust bearing is connected; The other end and servo-actuated dolly 9 are connected through screw mandrel; The outer end that connects is equipped with nut 7, and servo-actuated dolly 9 rolls with slideway 10 and is connected, and servo-actuated dolly 9 can be along slideway 10 scroll-up/down.
Embodiment 2
Basic identical with embodiment 1, different is that screw mandrel 6 heads are connected with reducing motor, and reducing motor has encoder, finally can realize the accurate adjustment of roller-way 4 height through electrical control.Reducing motor and electric control system belong to the outsourcing product, and electric control system is the common practise in the electric field.Top shoe 2 and sliding block 3 be shaped as right angled triangle, angle 14 is for satisfying the angle of self-locking between top shoe 2 and the sliding block 3, the hypotenuse of two slide blocks is a contact edge, can slide along hypotenuse.
The operation principle of embodiment is: when rotary screw 6, because slideway 10 along continuous straight runs are irremovable, move forward so screw mandrel 6 must spur draw-bar seat 13; Draw-bar seat 13 is rigidly connected with roller-way 4, top shoe 2; Must spur top shoe 2 and move up along sliding block 3, in this simultaneously, trunnion shaft 8 also drives servo-actuated dolly 9 and moves up along slideway 10; Make the active force of screw mandrel 6 be in forever on the horizontal direction, finally realize the adjusting of roller-way 4 height.
Parts that present embodiment is not described in detail and structure belong to well-known components and the common structure or the conventional means of the industry, here not narration one by one.
