Description

Technical Field

[0001] This utility model belongs to the field of roller bracket technology, and specifically relates to a roller bracket. Background Technology

[0002] Before the support frame was available, replacing the rubber ring required a lot of manpower to lift the roller and place it on the ground. The unpredictable factors during the roller lifting process made each person carrying the roller feel like they had a time bomb. If they were not careful, the roller could fall off and injure them.

[0003] Currently, the existing textile roller with announcement number CN108048966A includes a support body, a rack seat, and fastening screws. The support body has an inner semi-circular arc I with a recessed cavity at the bottom and fixed steps on both sides. The bottom of the inner semi-circular arc I has a square groove with several through holes II inside the square groove. The rack seat has a semi-circular ring on top and a square bar below. The semi-circular ring has an inner semi-circular arc II with several racks evenly distributed on its inner surface. The bottom of the square bar has several screw holes. The rack seat is installed into the inner semi-circular arc I, and the square bar is embedded in the square groove. The fastening screw passes through the through holes II and is screwed into the screw holes. This invention is a splicing type. After long-term use, when the rack wears or breaks, the rack seat can be removed and replaced. The support body can be reused, which greatly reduces the cost of use and maintenance.

[0004] However, there is a problem: the existing support structure can only provide support and cannot lift the heavy rollers. Utility Model Content

[0005] This solution provides a roller bracket to address the problem of the bracket being unable to be raised or lowered, which necessitates manual lifting to replace the rubber ring.

[0006] This solution provides a roller bracket, including:

[0007] Support unit: Used to support the rollers;

[0008] Fixing unit: used to fix the roller;

[0009] Lifting unit: The lifting unit includes an air frame, an air pump and a telescopic block. The air frame is connected to the air pump, the telescopic block is slidably and sealed to the air frame, and the fixing unit is set on the telescopic block.

[0010] The principle of this solution is as follows: When the rubber ring needs to be replaced, the operator places the air frame under the roller gripping tube and places the rubber ring to be replaced on the air frame. Then, the air pump is started, causing the telescopic block to move upward. The upward movement of the telescopic block will drive the fixing unit upward, so that the fixing unit moves to the gripping tube position, and then the fixing unit closes to fix the gripping tube. Then, the operator fixes the support unit on the fixing unit, so that the support unit supports the gripping tube.

[0011] After completing the preparations, the operator restarts the air pump, and the fixing unit and support unit move upward with the gripping tube, causing the roller to lift. At this point, the operator can replace the rubber ring.

[0012] The beneficial effects of this solution are as follows: 1. By automatically fixing and raising the roller through a mechanical device, the opportunity for operators to directly contact heavy equipment is reduced, thus lowering the risk of safety accidents caused by human error. 2. By adjusting the position of the telescopic block with an air pump, the height of the roller can be precisely controlled, ensuring that each operation step is performed under optimal conditions.

[0013] Furthermore, the support unit includes a main body and an arc-shaped support ring. The main body is detachably and fixedly connected to the fixing unit, and the arc-shaped support ring is fixedly connected to the main body and cooperates with the roller.

[0014] The air pump starts, causing the fixing unit to rise to the roller gripping tube position. The fixing unit closes and clamps the gripping tube, achieving initial fixation. The main body of the support unit is then secured to the fixing unit using fixing bolts. The arc-shaped support ring on the support unit automatically conforms to the outer wall of the roller gripping tube, forming a support point. The air pump is restarted, and the fixing unit and support unit together raise the roller as a whole. After replacing the rubber ring, the fixing unit is released, and the air pump controls the telescopic block to move downward, allowing the gripping tube to rest back on the base. The support unit can then be quickly removed and restored to its original position.

[0015] The arc-shaped support ring of this mechanism fits tightly against the outer wall of the roller gripper tube, effectively distributing the weight of the roller and preventing tilting or slippage due to uneven force. Meanwhile, the detachable connection between the main body and the fixing unit allows the support unit to be quickly replaced or adjusted according to different models of roller gripper tubes.

[0016] Furthermore, the fixing unit includes a sliding plate and a positioning plate. The sliding plate is slidably connected to the telescopic block, and the positioning plate is fixedly connected to the sliding plate. The positioning plate cooperates with the roller.

[0017] When the fixing unit reaches the tube gripping position, the sliding plate is moved manually or automatically until the positioning plate clamps and positions the tube gripper, firmly fixing the roller. At this point, the support unit can be installed for further support. The air pump is restarted, causing the sliding plate, positioning plate, and roller to rise together, completing the roller lifting action.

[0018] The sliding plate of this mechanism can be adjusted to accommodate grippers of different sizes.

[0019] Furthermore, it also includes a protective plate, which cooperates with the main body and is disposed between the main body and the fixing unit.

[0020] The protective plate is placed between the main body and the fixed unit, and the three are fixed together by bolts or other connection methods. The protective plate adheres to the fixed unit, forming a physical isolation layer. During the support phase, when the roller is lifted, its weight is transferred to the fixed unit through the support body. The protective plate, as an intermediate buffer layer, plays a role in pressure dispersion, friction damping, and preventing displacement.

[0021] Simultaneously, it prevents direct contact between the main body and the fixed unit, avoiding wear or deformation caused by metal-to-metal collisions. During operation, if the roller experiences slight shaking or shifting, the protective plate can absorb some of the impact force; it also provides some protection against accidentally dropped small parts or tools, improving the overall safety and reliability of the system. Furthermore, the protective plate also acts as a width compensation mechanism, bridging the gap between the main body and the fixed unit.

[0022] Furthermore, it also includes a limiting block, which is fixedly connected to the protective plate and cooperates with the sliding plate. The limiting block is used to restrict the axial movement of the support unit and prevent the entire support unit from tilting when the pipe is lifted.

[0023] Furthermore, the support unit is provided in multiple ways, and the multiple support units are arranged linearly and equidistantly on the fixed unit, and the multiple support units are located on the same horizontal line.

[0024] By setting up multiple support units, the weight of the roller is distributed across multiple support points. Compared to single-point support or multi-point non-uniform support, multi-point uniform support can better distribute the load, reduce local stress concentration, and thus reduce the risk of structural failure.

[0025] Furthermore, there are two fixing units, which are arranged in a mirror image with the roller as the center.

[0026] Initially, the two fixed units are in an open state and not in contact with the roller gripping tube. When the air pump is started, the two fixed units move upward synchronously to the preset roller gripping tube position. The operator moves the sliding plate to move the two fixed units towards the center, and their positioning plates clamp the gripping tube parts on both sides of the roller, forming a symmetrical clamping force.

[0027] This mechanism uses two fixed units to symmetrically clamp the rollers, forming a stable clamping structure that prevents the rollers from tilting or slipping due to unilateral clamping. Furthermore, the dual-sided clamping structure is more resistant to accidental impacts than single-sided clamping; even if one side becomes slightly loose, the other side can still provide effective support, significantly improving fault tolerance and safety during operation.

[0032] like Figure 1 As shown:

[0033] This solution provides a roller bracket, including a lifting unit, a fixing unit, and a support unit 5. The lifting unit includes an air frame 1, an air pump, and a telescopic block 2. The air frame 1 and the air pump are connected via air pipes to form a closed air circuit system. The telescopic block 2 is connected to the air frame 1 by a sliding seal (e.g., using an O-ring seal and guide rail).

[0034] The air frame 1 is made of high-strength aluminum alloy or carbon steel with anodized / sprayed anti-rust treatment. The telescopic block 2 is made of cast iron or stainless steel, with good wear resistance and sealing performance. The air pump is an industrial-grade air compressor, equipped with overload protection and pressure regulating valve.

[0035] The fixed unit (two units) consists of a sliding plate 3 and a protective plate 52. The bottom of the sliding plate 3 is slidably connected to the top of the telescopic block 2 via a guide rail groove structure, enabling vertical movement. The positioning plate 6 is fixed to the sliding plate 3 by bolts or welding, and its inner side has a contoured groove to fit the shape of the roller gripping tube. The sliding plate 3 has threaded holes for clamping and fixing the roller.

[0036] The sliding plate 3 is made of 45# steel or T6061 aluminum alloy, and the surface coating enhances wear resistance. The positioning plate 6 is made of engineering plastic (such as nylon) or metal-coated structure to prevent scratching the roller gripper tube.

[0037] As attached Figure 1 , Figure 2 As shown:

[0038] The support unit 5 (multiple units, two in this embodiment, but four can also be provided) includes a main body 51, an arc-shaped support ring 53, a protective plate 52, and a limiting block 54;

[0039] The main body 51 is a solid steel block, which is connected to the threaded hole on the fixing unit by fixing bolt 4. The arc-shaped support ring 53 is welded to the main body 51 or integrally formed, and its arc surface fits the outer wall of the roller grip tube. The soft pad 55 is set on the outer wall of the arc-shaped support ring 53, located between the arc-shaped support ring 53 and the roller grip tube, and is used to protect the roller grip tube from being scratched by the arc-shaped support ring 53.

[0040] Multiple support units 5 are arranged linearly and equidistantly along the fixed unit, located on the same horizontal line, and jointly bear the weight of the roller. The main body 51 is made of Q235 carbon steel or 6061 aluminum alloy, and the arc-shaped support ring 53 is made of nylon 6, polyurethane or rubber composite material, which has good friction and cushioning performance.

[0041] The protective plate 52 is positioned between the main body 51 and the fixed unit, and is fixed to the main body 51 and the sliding plate 3 as a whole by fixing bolts 4. The protective plate 52 is attached to the fixed unit, forming a physical isolation layer. The limiting block 54 is fixed to the protective plate 52 and contacts the side of the sliding plate 3, serving as a lateral limiting function. There are two protective plates 52, located on the left and right sides of the main body 51 respectively, with the left protective plate 52 being shorter than the right protective plate 52.

[0042] The protective plate 52 is made of PE, ABS engineering plastic or silicone pads, and has both shock absorption and insulation functions.

[0043] The limiting block 54 is fixedly connected to the protective plate 52. The limiting block 54 is used to restrict the axial movement of the support unit 5 to prevent the support unit 5 from tilting as a whole when the pipe is lifted.

[0044] The limit block 54 is made of POM or stainless steel to ensure limiting accuracy and durability. The two fixing units are mirror-shaped with the roller center axis as the axis of symmetry, which can drive the clamping or opening synchronously, improving clamping stability and safety.

[0045] As attached Figure 1-3 As shown:

[0046] The main body 51 has a buckle 56 in the middle of the front, which allows the operator to hook it from above and then pull the buckle 56 to test the tightness and see if the main body 51 will fall off.

[0047] In operation, initially, the fixed unit is in the open position, and the support unit 5 is not installed. When the rubber ring needs to be replaced, the operator places the air frame 1 at an appropriate position below the roller. The air pump is started, and the lifting action begins. The air pump supplies air to the air frame 1, pushing the telescopic block 2 upward and causing the fixed unit to rise synchronously to the roller's gripping position.

[0048] The operator manually controls the sliding plate 3 to move towards the center, and the positioning plate 6 clamps the gripping parts on both sides of the roller, and clamps and fixes them with set bolts to complete the initial fixation. Multiple support units 5 are fixed to the appropriate-sized protective plates 52 in sequence, and then installed on the fixed unit in sequence. The arc-shaped support ring 53 automatically fits into the outer wall of the roller to form uniform support. The protective plate 52 isolates the main body 51 from the fixed unit, providing buffering and limiting functions, and the limiting block 54 plays a role in resisting axial force.

[0049] Restart the air pump to lift the roller. The lifting unit continues to raise the fixed unit and support unit 5 as a whole, and the roller is stably lifted to a suitable height, making it easy for operators to replace the rubber ring or perform other maintenance. After maintenance is completed, reset the equipment, turn off the air pump, release the air pressure, and the telescopic block 2 moves down; the fixed unit releases the gripping tube, and the support unit 5 can be quickly disassembled; the roller returns to its original position, the equipment is reset to zero, and it is ready for the next use.

[0050] The beneficial effects of this solution are as follows: 1. By automatically fixing and lifting the roller through a mechanical device, the opportunity for operators to directly contact heavy equipment is reduced, thus lowering the risk of safety accidents caused by human error. 2. The height of the roller can be precisely controlled by adjusting the position of the telescopic block 2 with an air pump, ensuring that each operation step is performed under optimal conditions. 3. The arc-shaped support ring 53 of this solution fits tightly against the outer wall of the roller gripper tube, effectively distributing the weight of the roller and preventing tilting or slippage due to uneven force. Simultaneously, the detachable connection between the main body 51 and the fixing unit allows the support unit 5 to be quickly replaced or adjusted according to different models of roller gripper tubes. 4. The support effectively reduces the contact area of ​​the roller, thereby reducing damage to the roller threads.
