Description

Technical Field

[0001] The utility model relates to the technical field of loopers, in particular to a wear-resistant double-line side looper. Background Art

[0002] Most of the rollers used in the loopers and pinch rolls of the cold-rolled galvanizing production line are connected to the bearings with tension sleeves. The principle is that there is a 1:12 matching taper between the paired bearings and the tension sleeves. A locking nut is provided on the end face of the tension sleeve. By rotating the locking nut, the outer diameter of the tension sleeve increases, and the tension sleeve and the inner wall of the bearing inner sleeve are squeezed, so that the taper between the tension sleeve and the inner hole of the bearing is tightened; at the same time, the inner diameter of the tension sleeve decreases, and a clamping force is generated between the inner ring of the tension sleeve and the steel rod, thereby achieving the purpose of positioning the bearing on the roller.

[0003] Currently published patent: CN217451487U, discloses a roller and looper. Two locking sleeves are connected to each end of the roller body. The locking sleeves press against the corresponding positioning sleeves on the side away from the spoke. The bearing is connected to the outside of the locking sleeves and is fixed. The roller has a spoke, and the two sides of the positioning sleeve press against the spoke and the locking sleeves, respectively, to achieve axial positioning of the locking sleeves. The bearing is connected to the roller via the locking sleeve, ensuring axial positioning between the bearing and the roller. The bearing is fixed and connected to the roller body via the locking sleeve, thus achieving the connection between the roller body and the bearing.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when the loop is installed, the bearing is connected to the roller through a locking sleeve to ensure the axial positioning between the bearing and the roller. However, the gap between the roller and the loop is likely to become larger and larger during long-term use, which in turn causes the roller to swing up and down inside the loop. The staff usually directly replaces the entire loop, which reduces the service life of the loop, not only increasing the economic loss, but also causing waste of resources. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a wear-resistant double-line side looper, which can solve the problem that the gap between the roller and the looper tends to become larger and larger during long-term use, thereby causing the roller to swing up and down inside the looper. The staff usually directly replaces the entire looper, which reduces the service life of the looper, not only increases the economic loss, but also causes the problem of waste of resources.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant double-line side looper, comprising a looper body and a bushing disassembly device; a bushing is slidably installed inside the looper body; the bushing disassembly device comprises four connecting protrusions, four bolts and four positioning key blocks, the four connecting protrusions are circularly and equidistantly fixedly connected to the outer surface of the bushing, the surface of the looper body is provided with four mounting slots, the four connecting protrusions are respectively slidably connected to the inside of the four mounting slots, the four bolts are circularly and equidistantly installed inside the looper body, and the surfaces of the four connecting protrusions are provided with threaded mounting holes.

[0007] Preferably, the surface of the loop body is circular and has six threaded notches equidistantly formed thereon.

[0008] Preferably, the four bolts are respectively threadedly connected to the inside of the four threaded mounting holes.

[0009] Preferably, the surface of the loop body is circular and has four nut placement holes equidistantly provided thereon, and the nuts of the four bolts are respectively placed inside the four nut placement holes.

[0011] Preferably, the four positioning key blocks are circular and equidistantly fixed to the outer surface of the bushing, and the four positioning key blocks are slidably installed inside the four positioning key slots respectively.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This wear-resistant double-line side looper hides the nuts of the four bolts inside the four nut placement holes, which can maintain the flatness of the looper body surface and will not affect the installation of the looper body. At this time, the bushing can be replaced. The staff can replace the bushing alone and no longer need to replace the looper body. This method indirectly improves the wear resistance of the looper body and extends the service life of the looper body, which not only reduces economic losses but also reduces resource waste.

[0025] When the loop body 1 is in use, the staff can install the loop body 1 into the interior of the threaded groove 2 through the bolt installation, install and fix the loop body 1, and insert the shaft rod into the interior of the bushing 3. After long-term use, when the gap between the shaft rod and the inner wall of the bushing 3 becomes larger, the staff can rotate the bolt 6 with a wrench. The bolt 6 rotates and gradually moves to the rear side and out of the interior of the loop body 1 through the threaded connection between the bolt 6 and the threaded mounting hole 8. After the staff removes the four bolts 6 in the same way, the staff slides the bushing 3 to the front side. The bushing 3 slides to the front side and drives the four connecting protrusions 4 to slide to the front side and move out of the interior of the four mounting slots 5 to complete the disassembly. Then the staff takes out a new bushing 3 and slides the bushing 3 into the interior of the loop body 1. The bushing 3 slides and drives The four connecting protrusions 4 slide into the inside of the four mounting slots 5.

After long-term use, when the gap between the shaft rod and the inner wall of the bushing 3 becomes larger, the staff can rotate the bolt 6 with a wrench. The bolt 6 rotates and gradually moves backward and out of the interior of the looper body 1 through the threaded connection between the bolt 6 and the threaded mounting hole 8. The staff slides the bushing 3 to the front side, and the bushing 3 slides to the front side and drives the four connecting protrusions 4 to slide forward and out of the interior of the four mounting slots 5 to complete the disassembly, and then The staff then takes out a new bushing 3 and slides the bushing 3 into the interior of the loop body 1. The bushing 3 slides and drives the four connecting protrusions 4 to slide into the interior of the four mounting slots 5. Then, after the staff inserts the four bolts 6 into the interior of the four nut placement holes 7, they rotate the bolts 6 with a wrench. The bolts 6 rotate and enter the interior of the threaded mounting hole 8 to complete the replacement of the bushing 3. The bushing 3 slides and drives the four positioning key blocks 10 to slide into the interior of the four positioning key slots 9. The stability of the connection between the loop body 1 and the bushing 3 is increased through the connection between the four positioning key blocks 10 and the four positioning key slots 9.
