Description

Technical Field

[0001] This utility model relates to the field of support frame technology, specifically to a support frame for anti-corrosion coating of the inner wall of the stabilizing roller shell of a papermaking machine. Background Technology

[0002] In the papermaking process, the stabilizing roll of the papermaking machine is a key transmission component that has to withstand the effects of pulp moisture, chemical additives and mechanical loads for a long time. Its inner wall is prone to corrosion, rust and damage, which will not only shorten the service life of the stabilizing roll, but may also cause the roll body to run unbalanced and affect the paper forming quality. Therefore, it is necessary to regularly apply anti-corrosion coating to the inner wall of the stabilizing roll shell.

[0003] In the traditional operation mode of anti-corrosion coating of the inner wall of the stabilizing roller shell in papermaking machines, the industry generally uses simple brackets or manual lifting to fix the stabilizing roller. Among them, the simple brackets are mostly welded fixed metal frame structures, which only have basic load-bearing functions and have no lifting and adjustment design. Their support height is fixed after the production is completed and cannot be flexibly adjusted according to the actual operation scenario. In actual coating operations, there are individual differences in the height of operators, and different operators have different comfortable working heights. The fixed height simple brackets can only fit a few people. Most operators need to bend over, stand on tiptoe, or use something to step on in order to work. Over time, this can easily cause fatigue and even increase the risk of back and leg strain. Utility Model Content

[0009] Preferably, the top ends of the four telescopic rods are fixedly connected to the top of the connecting seat to support the connecting seat and make the vertical movement of the connecting seat more stable.

[0010] Preferably, the clamping mechanism includes a load-bearing frame, which is symmetrically and fixedly connected to the top of the connecting seat.

[0014] 1. This is a support frame for anti-corrosion coating on the inner wall of the stabilizing roller shell of a papermaking machine. The lifting mechanism, through the cooperation of a two-way screw and a hinged rod, can precisely adjust the height of the stabilizing roller to adapt to the height requirements of operators of different heights or different coating positions. The telescopic rod provides stable support for the connecting seat, and the limiting rod limits the movement of the moving block to ensure smooth lifting without shaking and prevent the anti-corrosion material from spilling during coating.

[0015] 2. This anti-corrosion coating support frame for the inner wall of the stabilizer roll housing in a papermaking machine has a clamping mechanism that drives the arc-shaped clamping plate to open and close synchronously through gear meshing. It can quickly clamp stabilizer rolls of different specifications with uniform and firm clamping force. The load-bearing frame placement surface and the arc-shaped clamping plate clamping surface are both made of rubber to avoid hard contact with the stabilizer roll surface and prevent the roll body from being scratched or worn.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figure 1-3 This utility model provides a technical solution: a support frame for anti-corrosion coating of the inner wall of the stabilizing roller shell of a paper machine, including a base 1, universal wheels 2 are symmetrically fixedly connected to the bottom of the base 1 in the front, back and left and right, a push handle 3 is fixedly connected to the top right side of the base 1, a lifting mechanism 4 is provided on the top of the base 1, and a clamping mechanism 5 is provided on the top of the lifting mechanism 4.

[0027] The lifting mechanism 4 includes a first fixed frame 41, which is fixedly connected to the top of the base 1. A first servo motor 42 is fixedly connected to the right side of the first fixed frame 41. A bidirectional lead screw 43 is fixedly connected to the output end of the first servo motor 42. Limiting rods 44 are symmetrically fixedly connected to the left and right sides of the inner wall of the first fixed frame 41. Moving blocks 45 are symmetrically threaded to the surface of the limiting rods 44. A first hinge frame 46 is symmetrically fixedly connected to the top of the two moving blocks 45. A hinge rod 47 is hinged inside the first hinge frame 46. A second hinge frame 48 is hinged to the other end of the hinge rod 47. A lifting plate 49 is fixedly connected to the top of the second hinge frame 48. A connecting seat 411 is fixedly connected to the top of the lifting plate 49. Telescopic rods 412 are symmetrically fixedly connected to the top of the base 1.

[0028] The left end of the bidirectional lead screw 43 is rotatably connected to the left side of the inner wall of the first fixed frame 41.

[0029] The two movable blocks 45 have holes on their left and right sides that match the limiting rod 44. The surfaces of the two movable blocks 45 are penetrated and slidably connected to the holes. The limiting rod 44 limits the two movable blocks 45, so that the two movable blocks 45 move towards each other as the bidirectional lead screw 43 rotates.

[0030] The top ends of the four telescopic rods 412 are fixedly connected to the top of the connecting seat 411, providing support for the connecting seat 411 and making the vertical movement of the connecting seat 411 more stable.

[0031] Example 2

[0032] Please see Figure 4 Furthermore, based on Embodiment 1, a clamping mechanism 5 is obtained.

[0033] The clamping mechanism 5 includes a load-bearing frame 51, which is symmetrically and fixedly connected to the top of the connecting seat 411. A second fixed frame 52 is fixedly connected to the top of the connecting seat 411. Rotating shafts 53 are symmetrically and rotatably connected to the inner walls of the second fixed frame 52. Gears 54 are fixedly connected to the surfaces of the two rotating shafts 53. A second servo motor 55 is fixedly connected to the right side of the second fixed frame 52 near the front. Rotating blocks 56 are symmetrically and fixedly connected to the surfaces of the two rotating shafts 53. Arc-shaped clamping plates 57 are fixedly connected to the top of the four rotating blocks 56.

[0034] The output end of the second servo motor 55 is fixedly connected to the right end of the rotating shaft 53 near the front of the inner wall of the second fixed frame 52, and the two gears 54 mesh with each other.

[0035] The placement surfaces of the two load-bearing frames 51 and the clamping surfaces of the four arc-shaped clamping plates 57 are all made of rubber to protect the surface of the stabilizing roller.

[0036] In actual operation, when this device is used, the stabilizing roller shell is placed on two load-bearing frames 51, and then the second servo motor 55 is started. After the second servo motor 55 starts, it drives the rotating shaft 53 to rotate, and the gear 54 fixed on the rotating shaft 53 rotates accordingly. Since the gears 54 on the surfaces of the two rotating shafts 53 mesh with each other, the two rotating shafts 53 achieve synchronous and opposite rotational motion. Each rotating shaft 53 has a rotating block 56 symmetrically fixed on its surface. The top of the rotating block 56 is fixedly connected to the arc-shaped clamping plate 57. When the rotating shafts 53 rotate synchronously in opposite directions, they drive the rotating block 56 to rotate around the axis of the rotating shaft 53, causing the two arc-shaped clamping plates 57 on the same side to close inward or open outward. When the arc-shaped clamping plates 57 close, they can clamp and fix the roller body from both sides.

[0037] After the first servo motor 42 starts, its output end drives the bidirectional lead screw 43 to rotate at the rotation connection point on the left side of the inner wall of the first fixed frame 41, converting the power of the first servo motor 42 into rotational motion of the bidirectional lead screw 43. The symmetrical limiting rods 44 on the left and right sides of the inner wall of the first fixed frame 41 form a lateral limit on the two moving blocks 45. When the bidirectional lead screw 43 rotates, because the threads at both ends of the bidirectional lead screw 43 rotate in opposite directions, the two moving blocks 45 move synchronously towards each other along the limiting rods 44. The first hinge frame 46 at the top of the moving block 45 and the hinge rod One end of the hinge rod 47 is hinged, and the other end of the hinge rod 47 is hinged to the second hinge frame 48, which is fixed to the bottom of the lifting plate 49. When the two moving blocks 45 move towards each other, they push the lifting plate 49 upward. Conversely, when the moving blocks 45 move away from each other, the lifting plate 49 falls back down, thus achieving lifting adjustment. At the same time, the top of the telescopic rods 412, which are symmetrically arranged at the top of the base 1, are fixed to the connecting seat 411. During the lifting process, they provide vertical support to the connecting seat 411, preventing the connecting seat 411 from tilting due to the weight of the stabilizing roller, and ensuring that the lifting action is smooth and without shaking.
