Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting chain technology, specifically relating to a non-slip and wear-resistant lifting chain. Background Technology
[0002] Lifting chains are chains used for lifting, traction, or securing heavy objects. They are widely used in industries such as manufacturing, construction, shipbuilding, and mining. Their main function is to lift and move large equipment and goods. They are usually made of high-quality alloy steel or stainless steel, which can withstand large tensile forces. The chain structure is flexible and can adapt to various complex lifting and securing needs.
[0003] In some existing lifting chains, the chain plates, due to their structure and installation location, experience concentrated stress. Under prolonged high-intensity conditions, the gaps between adjacent chain plates gradually increase due to continuous friction. This not only weakens the tightness of the chain plates and significantly increases the risk of slippage during lifting operations, but also further exacerbates the wear of the chain plates and shortens the chain's service life, causing considerable inconvenience. Utility Model Content
[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a non-slip and wear-resistant lifting chain. This addresses the issue mentioned in the background art where, during use, the chain plates are subject to concentrated stress due to their structure and installation location. Under prolonged high-intensity conditions, the gaps between adjacent chain plates gradually increase due to continuous friction. This not only weakens the tightness of the chain plates and significantly increases the risk of slippage during lifting operations, but also further exacerbates the wear of the chain plates and shortens the chain's service life, causing considerable inconvenience.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-slip and wear-resistant lifting chain, comprising a main body mechanism and an abutting mechanism disposed on the outside of the main body mechanism. The main body mechanism includes a chain plate, and the abutting mechanism includes a plurality of limiting screws symmetrically arranged on one side of the chain plate and threadedly connected to them. A slider is threadedly connected to the outer side of the bottom end of the limiting screws. A sliding arm is slidably connected to the outer side of the slider. A chain plate is slidably connected to the outer side of the sliding arm. An arc-shaped piece is fixedly connected to one side of the sliding arm. A fixing block is fixedly connected to one side of the arc-shaped piece. A plurality of bases are symmetrically arranged on the inner side of the fixing block. A spring is fixedly connected to the inner side of the base. A top block is fixedly connected to the top of the spring. A fixing block is movably connected to the outer side of the spring and the top block. A ball bearing is rotatably connected to the inner side of the top of the top block.
[0006] Preferably, a plurality of chain plates are symmetrically arranged, a sleeve is fixedly connected to the inner side of the chain plate, a limit pin is locked and connected to the inner side of the sleeve, and a roller is rotatably connected to the outer side of the sleeve.
[0007] Preferably, a washer is movably connected to the outer side of the top end of the limiting screw, and a chain plate is movably connected to the outer side of the washer.
[0008] Preferably, a limiting piece is fixedly connected to one side of the inside of the moving arm, and the limiting piece is located on one side of the slider.
[0009] Preferably, a reinforcing rib is fixedly connected to one side of the fixing block, and two reinforcing ribs are symmetrically arranged. An arc-shaped piece is fixedly connected to one side of the reinforcing rib.
[0010] Preferably, a buffer pad is fixedly connected to the top of the arc-shaped piece and the fixing block, and the buffer pad is made of a flexible material.
[0011] Preferably, one side of the limiting screw and one side of the chain plate are on the same horizontal plane.
[0012] Preferably, the ball is made of stainless steel, and a top block is rotatably connected to the outside of the ball.
[0013] Compared with the prior art, this utility model provides a non-slip and wear-resistant lifting chain, which has the following beneficial effects: 1. This utility model uses ball bearings to assemble the main body mechanism with chain plates, sleeves, rollers, and limiting pins to form a chain. Based on the position of the empty area in the middle of the chain plate, rotating counterclockwise loosens each limiting screw, reducing the pressure of the slider's outer wall pressing against the inner wall of the moving arm, thus releasing the restriction on the moving arm's position. Then, the moving arm slides within the chain plate, moving the arc-shaped piece until the ball bearings above the fixed block are in the desired horizontal position. During the movement of the moving arm, the ball bearings, through rolling, consistently support the chain plate without abrading its outer wall. Rotating the limiting screws clockwise tightens the slider. By increasing the pressure of the outer wall of the slider against the inner wall of the sliding arm, the position of the sliding arm is fixed, so that the ball bearings are at the required point, the middle of the supporting chain plate is left empty, and then the main body mechanism is used for hoisting. Because the outer chain plate is supported by the spring-driven top block and the ball bearings, its stability is greatly improved during use. This reduces the pressure and wear of the inner chain plate by the outer chain plate during shaking. While effectively reducing the risk of slippage, it also reduces the damage caused by the chain plates rubbing against each other due to shaking, thus ensuring the service life of the chain. 2. By setting a gasket, this utility model can effectively reduce the loosening of the limit screw during long-term use, thus ensuring the stability of the positioning capability of the limit screw; 3. By setting a limiting piece, this utility model can effectively reduce the risk of the arm falling due to excessive movement.
[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4This utility model provides a technical solution: a non-slip and wear-resistant lifting chain, including a main body mechanism 1 and an abutting mechanism 2 disposed on the outside of the main body mechanism 1. The main body mechanism 1 includes a chain plate 101. The abutting mechanism 2 includes a plurality of limiting screws 201 threadedly connected to one side of the chain plate 101. A slider 202 is threadedly connected to the outer side of the bottom end of the limiting screw 201. A sliding arm 203 is slidably connected to the outer side of the slider 202. The chain plate 101 is slidably connected to the outer side of the sliding arm 203. An arc-shaped piece 204 is fixedly connected to one side of the sliding arm 203. A [missing information - likely a component or component] is fixedly connected to one side of the arc-shaped piece 204. A fixed block 205 has several bases 206 symmetrically arranged on its inner side. A spring 207 is fixedly connected to the inner side of each base 206. A top block 208 is fixedly connected to the top of each spring 207. The fixed block 205 is movably connected to the outer side of the spring 207 and the top block 208. A ball bearing 209 is rotatably connected to the inner side of the top of the top of the top block 208. After assembling the main body mechanism 1 with the chain plate 101, sleeve 102, roller 103 and limit pin 104, a chain is formed. According to the position of the empty area in the middle of the chain plate 101, the limit screws 201 are rotated counterclockwise and loosened to lower the slider. The outer wall of slider 202 presses against the inner wall of sliding arm 203, releasing the restriction on the position of sliding arm 203. Then, sliding arm 203 slides within chain plate 101, moving arc plate 204 until the ball bearing 209 above fixed block 205 is in the desired horizontal position. During the movement of sliding arm 203, the ball bearing 209 supports chain plate 101 without abrading the outer wall of chain plate 101 by rolling. Rotating limit screw 201 clockwise tightens slider 202, thereby increasing the pressure of the outer wall of slider 202 against the inner wall of sliding arm 203, thus fixing the position of sliding arm 203. This allows the ball bearings 209 to be positioned at the required points, supporting the middle of the chain plate 101 while leaving the rest empty. During the hoisting process via the main body mechanism 1, the outer chain plate 101 is supported by the spring 207 pushing the top block 208 in conjunction with the ball bearings 209. Therefore, its stability is greatly improved during use, thereby reducing the force that causes the outer chain plate 101 to squeeze and wear the inner chain plate 101 during shaking. This effectively reduces the risk of slippage and also reduces the possibility of damage caused by mutual friction between the chain plates 101 due to shaking, thus ensuring the service life of the chain.
[0018] In this utility model, preferably, several chain plates 101 are symmetrically arranged, and a sleeve 102 is fixedly connected to the inner side of the chain plate 101. A limit pin 104 is locked and connected to the inner side of the sleeve 102, and a roller 103 is rotatably connected to the outer side of the sleeve 102. After the main body mechanism 1 is assembled with the chain plate 101, sleeve 102, roller 103 and limit pin 104, a chain is formed, and the chain is used for hoisting operations.
[0019] In this utility model, preferably, a washer 3 is movably connected to the outer side of the top end of the limiting screw 201, and a chain plate 101 is movably connected to the outer side of the washer 3. This can effectively reduce the loosening range of the limiting screw 201 during long-term use and ensure the stability of the positioning capability of the limiting screw 201.
[0020] In this invention, preferably, a limiting piece 4 is fixedly connected to one side of the inside of the sliding arm 203. The limiting piece 4 is located on one side of the slider 202, which can effectively reduce the risk of the sliding arm 203 falling due to excessive movement.
[0021] In this utility model, preferably, a reinforcing rib 5 is fixedly connected to one side of the fixing block 205, and two reinforcing ribs 5 are symmetrically arranged. An arc-shaped piece 204 is fixedly connected to one side of the reinforcing rib 5, which can effectively ensure the stability of the structure between the arc-shaped piece 204 and the fixing block 205.
[0022] In this utility model, preferably, a buffer pad 6 is fixedly connected to the top of the arc-shaped piece 204 and the fixing block 205. The buffer pad 6 is made of flexible material, which can further reduce the wear on the outer wall of the chain plate 101 during the contact process.
[0023] In this utility model, preferably, one side of the limiting screw 201 and one side of the chain plate 101 are on the same horizontal plane, which can effectively ensure the flatness of the outer surface of the chain plate 101.
[0024] In this invention, preferably, the ball bearing 209 is made of stainless steel, and a top block 208 is rotatably connected to the outer side of the ball bearing 209, which can effectively reduce the risk of jamming caused by oxidation and corrosion.
[0025] The working principle and usage process of this utility model are as follows: In use, the main body mechanism 1 is assembled with the chain plate 101, sleeve 102, roller 103, and limiting pin 104 to form a chain. Based on the position of the empty area in the middle of the chain plate 101, each limiting screw 201 is rotated counterclockwise and loosened, reducing the pressure of the outer wall of the slider 202 on the inner wall of the moving arm 203, thus releasing the restriction on the position of the moving arm 203. Then, the moving arm 203 slides within the chain plate 101, moving the arc-shaped piece 204 until the ball bearing 209 above the fixed block 205 is in the desired horizontal position. During the movement of the moving arm 203, the ball bearing 209, through rolling, can consistently support the chain plate 101 without abrading its outer wall. The chain plate 101 is rotated clockwise. The limiting screw 201 tightens the slider 202, thereby increasing the pressure of the outer wall of the slider 202 on the inner wall of the moving arm 203, fixing the position of the moving arm 203. This allows the ball bearing 209 to support the middle of the chain plate 101 at the required point, leaving the rest empty. During the hoisting process via the main body mechanism 1, the outer chain plate 101 is supported by the spring 207 pushing the top block 208 in conjunction with the ball bearing 209. Therefore, its stability is greatly improved during use, thereby reducing the pressure and wear of the inner chain plate 101 caused by the outer chain plate 101 during shaking. This effectively reduces the risk of slippage and also reduces the damage caused by the chain plates 101 rubbing against each other due to shaking, ensuring the service life of the chain.
