Description

A kind of horizontal looping car turns to rope wheel replacing device
Technical field
Quick-replaceable horizontal looping car rope sheave can be turned to the present invention relates to a kind of in cold rolling sour rolling mill maintenance process Device, belongs to workshop tools technical field.
Background technology
Kink is to be used to store strip, it is ensured that the device of cold rolling mill acid rolling line continuous and steady operation, looping car is in steel wire Moved back and forth under the traction of rope, in distraction procedure, steel wire rope needs to change trend by the steering rope sheave on looping car. In actual production application, occur to turn to rope sheave bearing abnormal noise often, the phenomenon that retainer is damaged is, it is necessary to which parking immediately is changed and turned To rope sheave.But the narrow space residing for looping car, without appropriate lifting point.And steering rope sheave diameters and weight are all larger, Though middle endoporus is that gap coordinates with bearing pin, gap value very little, when lifting turns to rope sheave, rope sheave is slightly tilted, Turning to rope sheave can not just hang out.Change turn to rope sheave common method be turn to rope sheave bottom place three it is small-sized very heavy Top, three jack synchronous ascendings.Because jack lower space is narrow and small, start to wait until using the small jack of stroke Turn to after the space increase between rope sheave and vehicle frame, then change the larger jack of stroke, separated until turning to rope sheave with wheel shaft, Finally make a concerted effort to have bad luck away rope sheave from the perforate of kink side wall using Unwinding chains.Operating process is very cumbersome, it is necessary to expend big The manpower and materials of amount.General replacement time is up to 6 to 8 hours.Being normally carried out for production is had a strong impact on.
The content of the invention
Rope sheave is turned to it is an object of the invention to the drawback for prior art there is provided a kind of horizontal looping car more to change the outfit Put, to improve the replacing efficiency for turning to rope sheave, it is ensured that production is normally carried out.
Problem of the present invention is realized with following technical proposals:
A kind of horizontal looping car turns to rope wheel replacing device, and composition includes sleeve, lift shaft, rotates nut and is arranged in sleeve Multiple pull bars of surrounding, the sleeve is vertically installed at by base on the wheel shaft for turning to rope sheave, is provided with the barrel of sleeve The axial slide corresponding with each pull bar, the lower end of the lift shaft is located in sleeve and is provided with and each chute on sleeve Corresponding ear mount, one end of each pull bar is hinged with the ear mount in corresponding chute, and the other end is provided with turning to the work on rope sheave The corresponding pulling claw in skill hole;The rotation nut is arranged on sleeve upper end by thrust ball bearing and matched somebody with somebody by screw thread with lift shaft Close, the side of rotation nut is provided with torsion bar.
Above-mentioned horizontal looping car turns to rope wheel replacing device, and the pulling claw is connected by pulling claw support with pull bar, described to draw Pawl support is located in the fabrication hole turned on rope sheave, and upper end and the pull bar of pulling claw support are hinged, and the pulling claw is hooked on steering rope The lower surface of wheel, the root of pulling claw is inserted in the pulling claw groove of pulling claw pedestal lower end and is connected by pin with pulling claw support.
Above-mentioned horizontal looping car turns to rope wheel replacing device, and the base is bolted on the wheel shaft for turning to rope sheave On, it is provided with the chuck corresponding with each chute on sleeve on base top.
Above-mentioned horizontal looping car turns to rope wheel replacing device, and the lift shaft and the screw thread for rotating nut are rectangular thread.
Above-mentioned horizontal looping car turns to rope wheel replacing device, and the pull bar sets four, and they are uniformly distributed around sleeve.
The power that multiple pull bars of the present invention are provided by rotation nut is safely and smoothly taken out rope sheave is turned to from wheel shaft Go out.The device solves the dismounting problem that kink turns to rope sheave well, not only substantially increases the replacing efficiency for turning to rope sheave, Being smoothed out for production is ensure that, and reduces the labor intensity of workman.

Embodiment
The invention provides the device that a kind of fast changeable turns to rope sheave.The device utilizes worm drive principle, will return Transhipment is dynamic to be converted to linear motion, and mechanism operates steadily, and can transmit larger axial force, while also having auto-lock function.Should Depending on the size of device can be according to the space size residing for scene steering rope sheave.
Referring to Fig. 1~Figure 10, the invention mainly comprises base 1, sleeve 2, lift shaft 3, rotation nut 4, pull bar 5, pulling claw Support 6, pulling claw 7, pin 8, torsion bar 9, thrust ball bearing 11.Wherein, three a diameter of 17mm hole is evenly equipped with base 1, can It is fixed on the bolt connection by M16 on the wheel shaft 14 for turning to rope sheave 13.The upper surface of base 1, which is welded with, along the circumferential direction to be divided Four chuck 16 of cloth, the rotation for limiting sleeve 2.The lower end of lift shaft 3 is provided with ear mount 15, for cylinder lever connecting rod 5, sleeve 2 Using wall thickness 20mm, external diameter 200mm steel pipe is processed into.The upper-end inner diameter of sleeve 2 is lathed 190mm, and depth is 30mm, is used for Lay thrust ball bearing.The barrel of sleeve 2 is provided with axial slide 10, and the lower end of chute 10 broadens(Whole chute is shaped as "convex" shaped), when the chuck 16 on base 1 is injected in the lower end of chute 10, sleeve will be fixed.The insertion sleeve 2 of lift shaft 3 It is interior, it can be slided up and down along inside sleeve 2.4 ear mounts 15 in lift shaft 3 can be slided up and down in chute 10.Lifting Axle 3 uses rectangular thread, and this screw thread can bear larger load, and operate steadily.Thrust ball bearing 11 is passed through and carried The threaded portion of lifting shaft 3, its lower end is leaned against on the boss on the inwall of sleeve 2.Nut 4 is rotated by being threaded into lift shaft 3, its Lower surface is pressed in the upper surface of thrust ball bearing 11.In the hole of one end insertion rotation nut 4 side of torsion bar 9.Pull bar 5 passes through pin Axle is connected in the ear mount of lift shaft 3.And axial restraint is carried out to bearing pin by jump ring.The other end of pull bar 5 is also by pin Axle is connected with pulling claw support 6, and axial restraint is carried out to bearing pin by jump ring.Pulling claw 7 is connected by pin 8 with pulling claw support 6.
The course of work of the present invention is as follows:
Base 1 is fixed on by bolt 12 on the wheel shaft 14 for turning to rope sheave.Lift shaft 3 is down to most by the torsion bar 9 on rotation nut 4 Low level.Now pulling claw 7 is respectively put into 4 fabrication holes for turning to rope sheave.And pulling claw 7 is caught on the following table for turning to rope sheave 13 Face.Rotation nut 4 is rotated clockwise manually, and lift shaft 3 can slowly be lifted along sleeve 2, while dropping pull bar 5.Four pulling claws Steering rope sheave 13 is caught on, rope sheave 13 will be smoothly turned to and is extracted out from the wheel shaft 14 for turning to rope sheave, it is high until turning to the bottom of rope sheave 13 In the wheel shaft 14 for turning to rope sheave.Again kink is had bad luck out with the Unwinding chains of side by rope sheave 13 is turned to.
The present invention is solved during kink steering rope sheave lifting well, due to residing narrow space, without appropriate Lifting point, and turn to the problem of steady lifting that causes of rope sheave heaviness is very difficult.Substantially reduce the work in Renewal process Intensity, safe operation is reliable.
