Abstract
The utility model relates to a water cooling device installed on conticaster roller, comprising a pipe casting which axially stretches into the roller and swivel joints installed at the two ends of the pipe casting. The water cooling device adopts the structure that one pipe casting penetrates through the whole roll shaft and the swivel joints are installed at the two ends of the pipe casting, so that the pipe casting is ensured to rotate along with the roller. Therefore, the water cooling device with the structure basically does not have water leakage problem, and reduces production cost at the same time since a connecting piece is saved.
Description
Affiliated technical field:
The utility model relates to a kind of water cooling plant that is installed on the caster roll.
Background technology:
Existing caster roll is to be made of by axial ways of connecting a plurality of section rollers, each section roller comprises roll body and axially passes the roll shaft of roll body, and connect by roller seat between adjacent two section rollers, the bearing that is used to support roll shaft is installed in roller seat, wherein, the roll shaft at two ends is an initiative roll shaft, and the roll shaft at middle part is driven roll shaft.Because conticaster directly contacts with high temperature billet steel when rolled plate, very easily be subjected to the erosion of high temperature billet steel, and easily cause its damage after corroding, so, in the prior art, in order to solve the problem that roller is damaged, the central region at roll shaft is provided with the passage that is used for the cooling water circulation usually, cooling-water duct promptly, and cooling-water duct is to be made of the pipe fitting that axially is installed in the roller middle part respectively.
Because prior art thinks that the main effect of pipe fitting is to guarantee that cooling water can continuous flow, rather than transmits the parts that moment of torsion makes the common rotation of connected two roll shafts, so, suitable seal member between the pipe fitting of adjacent two roll shafts, do not adopted.But, two rollers rotate because of can not reaching in power transmission fully synchronously; promptly when initiative roll shaft rotates; small relative displacement takes place in instantaneous meeting between driven roll shaft and the initiative roll shaft; so; cooperate how closely between simple pipe fitting and the roll shaft; after roller moves a period of time; pipe fitting can because of wearing and tearing or be subjected to the effect of twisting resistance and roll shaft between do not reach and closely cooperate; cause in the roll shaft and cooling water flow out of; and meeting splash everywhere after the water outflow is easy to make bearing to damage because of being subjected to water erosion, and damage of bearings can directly influence the operate as normal of roller; changing bearing needs to shut down, and then influences the conticaster operate as normal.
The name of Chinese patent 201189554Y number bulletin is called " being used for the leakage-proof apparatus on the continuous casting machine fan-shaped segment axle " and provides a solution.This device comprises a hollow, and the two ends of this hollow are respectively arranged with cannelure, and its central region is provided with the limiting section of projection radially outward, and is provided with elastic sealing element in cannelure.Its meaning is to want to utilize sealing and this dual mode of axial restraint to solve cooling water flow to go wrong to prolong the service life of roller inner bearing.Though this leakage-proof apparatus can be realized good sealing,, cause shorten its service life because of elastic sealing element damages under the effect of roller easily; In addition, because of this device is the parts that are used for connecting each section roller pipe fitting, its pipe fitting still adopts segmented structure, even and if the sealing of this device is good again, also can't compare with whole pipe fitting, cost of manufacture also can improve simultaneously.
Summary of the invention:
The purpose of this utility model provides a kind of water cooling plant on the continuous casting arbor of being installed in that utilizes whole pipe fitting and end can solve sealing and cost problem with the mode that roller rotates.
The water cooling plant that is installed on the caster roll that the utility model proposed comprises the swivel joint that axially extend into the pipe fitting in the roller and be installed in these pipe fitting two ends.
Described swivel joint is the single loop swivel joint.Position between described pipe fitting and the roller is fixed by key.
The water cooling plant that is installed on the caster roll that the utility model proposed adopts a pipe fitting to run through the structure of whole roll shaft, and swivel joint is installed at these pipe fitting two ends, so that pipe fitting can rotate with roller, so, the water cooling plant of this kind structure seepy question can not occur basically, simultaneously because of having omitted connector, thereby can reduce cost of manufacture; In addition, because the pipe fitting antileaking makes this device can protect bearing effectively, and then can prolong the service life of roller.
Description of drawings:
Accompanying drawing 1 is the outward appearance cross-sectional view that is installed in the embodiment of water cooling plant on the caster roll that the utility model proposes.
The specific embodiment:
Referring to Fig. 1, this figure provides the surface structure that is installed in the embodiment of water cooling plant on the caster roll that the utility model proposes.The pipe fitting 2 of this assembly axis in extending into roller 1 and the swivel joint 3 that is installed in these pipe fitting 2 two ends, and swivel joint 3 can adopt the single loop swivel joint, can further reduce cost.For pipe fitting 2 can be rotated synchronously with axle 1, between pipe fitting 2 and roller 1, key 4 is installed.Key 4 can be provided with as required, and in the ordinary course of things, the pipe fitting 2 that each section roller 1 is covered can be installed two keys 4.
Claims (3)
1, be installed in water cooling plant on the caster roll, it is characterized in that: this device comprises the swivel joint that axially extend into the pipe fitting in the roller and be installed in these pipe fitting two ends.
2, water cooling plant according to claim 1 is characterized in that: described swivel joint is the single loop swivel joint.
3, water cooling plant according to claim 1 is characterized in that: the position between described pipe fitting and the roller is fixed by key.
