[0002] In the metallurgical industry, it is very common to use water cooling for working rolls that are in direct contact with high-temperature plates, wires, and profiles. The cooling water flows into the working roll cavity through the rotary joint water inlet pipe, and the cold water exchanges heat with the roll body, and then is discharged through the rotary joint return pipe to achieve forced cooling.
[0003] The rotary joint and the working roll are usually connected by threads. For working rolls used for one-way rolling transmission, the appropriate thread direction can be selected for the rotary joint according to the direction of rotation of the roll, which can prevent it from loosening to a certain extent. However, for rolling, straightening and other working rolls that need to roll in both directions, the threaded connection between the rotary joint and the roll is very easy to loosen during the repeated forward and reverse rotation of the roll, and the cooling water flows out abnormally along the gap, causing water waste; at the same time, due to the lack of effective support, the gravity of the rotary joint and the internal cooling water will be transmitted to the threaded connection, causing radial stress concentration at the threaded connection, and the equipment is prone to damage.

[0025] The utility model provides a water-cooled rotary joint anti-loosening support device. Compared with the prior art, the semicircular mounting plates 110 of the two supporting bodies 100 are symmetrically arranged and mounted on the end surface of the flange end cover 600 through the first connecting piece 112 and the mounting hole 111. At this time, the semicircular locking sleeves 120 of the two supporting plates are arranged around the outer periphery of the connecting pipe 700 on both sides, and the two supporting plates are locked through the second connecting piece 132 and the connecting hole 131. The anti-slip structure 121 on the inner wall of the semicircular locking sleeve 120 is tightly matched with the outer wall of the connecting pipe 700, which can form an effective support for the connecting pipe 700 and prevent the connecting pipe 700 from rotating in the circumferential direction. The utility model provides a water-cooled rotary joint anti-loosening support device which can effectively fix the water-cooled rotary joint 300 on the working roll. During the forward and reverse rotation of the working roll, the rotary joint 300 will not loosen, thus avoiding overflow of cooling water. At the same time, the device can support the rotary joint 300 and the connecting pipe 700, thus avoiding stress concentration at the threaded connection and ensuring the normal service life of the equipment.
[0026] Specifically, the anti-skid structure 121 includes anti-skid teeth circumferentially arranged on the inner wall of the semicircular locking sleeve 120, and the length direction of the anti-skid teeth is consistent with the axial direction of the semicircular locking sleeve 120. The anti-skid teeth are clamped on the outer wall of the connecting tube 700, which can form an effective clamping and positioning structure to prevent the connecting tube 700 from circumferential rotation. Of course, the anti-skid structure 121 can also be a mesh-like anti-skid pattern or a matrix-arranged convex dot structure, etc., which will not be repeated here.
[0027] The mounting holes 111 are bolt holes, the first connectors 112 are mounting bolts, and the mounting bolts penetrate the mounting holes 111 to mount the semicircular mounting plate 110 on the flange end cover 600. Specifically, each semicircular mounting plate 110 has three mounting holes 111, which are arranged at equal angles.
[0028] The connecting hole 131 is a bolt hole, and the second connecting member 132 is a connecting bolt. The connecting bolt passes through two corresponding coaxial connecting holes 131 on the two support plates to relatively lock the support plates. Specifically, each connecting plate 130 is provided with two connecting holes 131 at intervals in the length direction.
[0029] The arc surfaces of the two semicircular mounting plates 110 together form an outer circle, and the inner walls of the two semicircular locking sleeves 120 form an inner circle, and the outer circle and the inner circle are coaxial. The two semicircular mounting plates 110 can be installed according to the outer circle of the flange end cover 600 to ensure that the two semicircular locking sleeves 120 can be tightly arranged around the outer circumference of the connecting pipe 700.
[0030] In addition, the semicircular mounting plate 110 and the support plate are integrally formed, and the semicircular mounting plate 110 and the support plate have sufficient strength and rigidity. If necessary, a reinforcing rib plate can be welded between the semicircular mounting plate 110 and the support plate.
[0031] The utility model also provides a working roll, which uses the above-mentioned water-cooled rotary joint anti-loosening support device. The working roll includes a working roll body 200 and a rotary joint 300. One end of the working roll body 200 is connected with a bearing seat 400, a shaft head 500 and a flange end cover 600 in sequence. The rotary joint 300 passes through the flange end cover 600, the shaft head 500 and the bearing seat 400 through a connecting pipe 700 and penetrates into the interior of the working roll body 200. The straight sides of the two semicircular mounting plates 110 are opposite and installed on the flange end cover 600. The semicircular locking sleeves 120 of the two support plates are clamped on both sides of the outer periphery of the connecting pipe 700.
[0032] The beneficial effect of a working roll provided by the utility model is that, compared with the prior art, since the working roll uses the above-mentioned water-cooled rotary joint anti-loosening support device, it has the same beneficial effect as the water-cooled rotary joint anti-loosening support device, which will not be repeated here.
[0033] The shape formed by the two symmetrically arranged semicircular mounting plates 110 is adapted to the end face shape of the flange end cover 600, that is, the outer circle edge formed by the semicircular mounting plates 110 is flush with the outer circle edge of the end face of the flange end cover 600. The multiple mounting holes 111 on the two semicircular mounting plates 110 are adapted to the multiple bolt holes opened on the end face of the flange end cover 600, that is, the number, position and hole diameter are the same.
[0034] In addition, the length of the support plate is not greater than the length of the connecting tube 700. When the two semicircular mounting plates 110 are mounted on the end surface of the flange end cover 600, the end of the support plate away from the semicircular mounting plate 110 will not interfere with the rotary joint 300. Generally, the length of the support plate is greater than 1 / 2 of the length of the connecting tube 700 to ensure the locking effect of the support plate on the connecting tube 700.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
