[0002] In modern hot-dip galvanizing, galvanizing and aluminum-plating continuous production lines, the strip steel plates are unwinding, cleaning and annealing furnaces before entering the plating tanks to complete the hot-dip plating operation. The production is then completed after coating control, cooling, skinning, straightening, passivation, infrared drying and coiling. Among them, skinning and leveling machines are used in the skinning process. Their main function is to level the coating surface and increase the roughness of the coating, so as to improve the adhesion of the coating during the subsequent oiling process and the surface oil storage capacity during the subsequent processing.

[0040] Combination Figures 1 to 6 As shown, the utility model discloses a disassembly device for a support roller bearing 70 of a smoothing machine of a continuous hot-dip coating production line, comprising: an upper crossbeam 10; a telescopic mechanism 20, the upper end of which is arranged on the lower side of the upper crossbeam 10, for lifting the upper crossbeam 10; a pull rod 30, the upper end of which is arranged on the lower side of the upper crossbeam 10; a lower crossbeam 40, which is connected and fixed to the lower end of the pull rod 30; two slider assemblies, which are slidably arranged on the lower crossbeam 40; the two slider assemblies have an extended state and a retracted state relative to the lower crossbeam 40; when the two slider assemblies are in the extended state, the two slider assemblies slide outward respectively to support the bearing 70.

[0041] Specifically, before disassembling the bearing 70, use a crane or other lifting equipment to lay the bearing seat 60 of the smoothing machine on the ground, and set the end cover of the bearing 70 upward and horizontally. Figure 1 As shown; the overhead crane is then used to place the support roller bearing 70 disassembly device of the continuous hot dip coating production line polishing machine of the present application (hereinafter referred to as the bearing 70 disassembly device) into the bearing 70. It should be noted that at this time, the sliding assembly is in a retracted state, and the two sliding block assemblies have no contact with the bearing 70;

[0042] After the bearing 70 disassembly device is placed in place, the two slider assemblies are operated so that the two slider assemblies slide outward respectively, and the slider assemblies in the extended state contact the lower end surface of the bearing 70 to support the bearing 70; at the same time, the telescopic mechanism 20 placed in the designated position extends to lift the upper beam 10, so that the distance between the upper beam 10 and the ground is increased, and then the lower beam 40 and the two slider assemblies are synchronously lifted, and finally the bearing 70 is pulled out of the bearing seat 60, eliminating the knocking process, making the entire disassembly process simple and time-saving. The bearing 70 pulled out of the bearing seat 60 together with the bearing 70 disassembly device can be transported to the ground under the hoisting action of the overhead crane.

[0043] In one embodiment, the lower cross beam 40 includes a mounting portion 410, and the mounting portion 410 is provided with a clearance groove 411, and the slotting direction of the clearance groove 411 is the same as the sliding direction of the slider assembly; a part of the slider assembly is slidably disposed in the clearance groove 411. Specifically, the mounting portion 410 is disposed on the upper side of the lower cross beam 40, and a part of the slider assembly is slidably disposed in the clearance groove 411, so that the slider assembly can be slidably disposed on the lower cross beam 40, and in the process of supporting and pulling out the bearing 70, the mounting portion 410 can limit the slider assembly.

[0044] Further, the slider assembly includes a slider 510 and a positioning key 520, the slider 510 is slidably disposed in the clearance groove 411; the slider 510 has an inner end and an outer end, the inner end and the positioning key 520 are detachably disposed, and the outer end is used to support the bearing 70. The part of the slider assembly referred to above that is slidably disposed in the clearance groove 411 specifically refers to the slider 510 being slidably disposed in the clearance groove 411, and in this embodiment, the two ends of the slider 510 are defined as the inner end and the outer end, wherein the inner end refers to the end of the slider 510 close to the central position of the bearing 70 disassembly device, and the outer end refers to the end of the slider 510 away from the central position of the bearing 70 disassembly device; the positioning key 520 and the inner end are detachably disposed, so as to limit the position of the slider 510 and the mounting portion 410 when connected, or to facilitate the removal of the slider 510 from the clearance groove 411 when disassembled.

[0045] Furthermore, when the two slider assemblies are in the extended state, the positioning key 520 abuts against the mounting portion 410, so as to utilize the mounting portion 410 to limit the slider 510, thereby preventing it from being separated from the bearing 70 disassembly device and causing failure during the pulling-out process, or causing the bearing 70 to fall off during transportation.

[0046] Furthermore, a fixing screw hole is provided at the inner end of the slider 510, and a countersunk hole is provided at the positioning key 520, and the countersunk hole is arranged corresponding to the fixing screw hole; the slider assembly also includes a bolt 530, and the bolt 530 is threadedly connected to the fixing screw hole after passing through the countersunk hole, so as to set the positioning key 520 at the inner end of the slider 510, and the positioning key 520 and the slider 510 can be detachably connected by tightening or loosening the bolt 530. In addition, the countersunk hole design enables the head of the bolt 530 to be received in the countersunk hole to avoid interference between the bolt 530 and other components.

[0047] In one embodiment, the lower cross beam 40 also includes a limit block 420, and the limit block 420 is arranged between the two slider assemblies; when the two slider assemblies are in a retracted state, the two slider assemblies are abutted against the limit block 420 to prevent the two slider assemblies from excessively retracting and disengaging from the bearing 70 disassembly device.

[0048] In one embodiment, the upper side surface of the mounting portion 410 is connected and fixed to the lower end of the pull rod 30 so as to reasonably utilize the position layout on the lower cross beam 40 so that the lower cross beam 40 can be made into a long strip shape to reduce manufacturing costs.

[0049] Regarding the placement of the telescopic mechanism 20 at a designated position, in one embodiment, the lower end of the telescopic mechanism 20 is placed on a bearing seat 60. In another embodiment, the telescopic mechanism 20 can be prevented from being placed on the ground.

[0050] In one embodiment, the telescopic mechanism 20 includes a jack, and the jack can be extended or retracted by hydraulic pressure or other means to lift up the upper beam 10.

[0051] In one embodiment, the upper cross beam 10 is provided with a hanging hole 110 for suspending by an overhead travelling crane.

[0052] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
