Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and more particularly to a self-lubricating elevator guide shoe structure. Background Art

[0002] Elevator guide shoes are important safety and mechanical components in elevator systems, mainly used to ensure the smooth operation of the elevator car in the vertical guide rails. The basic function of the guide shoe is to guide and stabilize the car or counterweight through friction with the guide rails to prevent it from deflecting or swinging. The guide shoe is usually made of high-strength metal materials and wear-resistant composite materials, and can withstand greater friction during long-term use. The guide shoe is set at the bottom of the elevator car or counterweight and cooperates with the vertical guide rails to ensure the smooth and stable up and down operation of the elevator.

[0003] The structural setting of elevator guide shoes needs to consider multiple factors, including friction, wear resistance, noise control and vibration resistance. Usually, the guide shoe is composed of an outer shell, an inner lining and an elastic material. The outer shell is responsible for supporting the overall structure of the guide shoe, and the inner lining reduces direct friction with the guide rail to avoid damage to the guide rail or the guide shoe. The elastic material is used to absorb the vibration generated during the operation of the elevator, improving stability and comfort. The setting of modern elevator guide shoes also focuses on environmental protection and noise reduction. Therefore, the composite materials used often have good shock absorption effects and reduce the noise level during elevator operation.

[0004] Existing elevator guide shoes generally use friction materials (such as rubber or polyurethane) to contact the guide rails. With time and increased use, the friction coefficient will gradually increase, causing the guide shoes to wear, thus affecting the smooth operation and safety of the elevator. To solve this problem, traditional technology reduces friction and wear by regularly adding lubricating oil or replacing guide shoes, and requires regular maintenance and refueling, which increases operation and repair costs. Excessive or uneven friction between the guide shoes and the rails will affect the smoothness of the elevator operation and cause noise. The regular lubrication process may not be complete and may still cause the guide shoes to wear too quickly.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a self-lubricating elevator guide shoe structure. Summary of the invention

[0006] The object of the present invention is to provide a self-lubricating elevator guide shoe structure to solve the above-mentioned problems.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0008] A self-lubricating elevator guide shoe structure comprises a shoe seat, a plurality of lubricating rollers and a plurality of lubricating balls, wherein a pair of guide shoe plates are fixedly installed at the front end of the shoe seat, a plurality of rotation grooves are opened at one end of the pair of guide shoe plates close to each other, and the plurality of lubricating rollers are rotatably connected in the plurality of rotation grooves respectively, a plurality of placement grooves are opened at one end of the pair of guide shoe plates far away from each other, and the plurality of placement grooves are respectively connected with the plurality of rotation grooves, a storage box is slidably connected in the placement groove, and a plurality of lubricating balls are all arranged in the storage box, and a filling box is fixedly connected at one end of the storage box close to the lubricating rollers, the stability and reliability of the guide shoe are enhanced by the arrangement of the shoe seat and the guide shoe plate, the front end of the guide shoe plate is fixedly contacted with the guide rail, thereby ensuring the smooth operation of the guide shoe and the durability in long-term use, and the plurality of rotation grooves and placement grooves of the guide shoe plate are arranged, which are conducive to the installation and operation of the lubricating rollers and the lubricating balls, and ensure the smooth operation of the elevator system.

[0009] As a further improvement of the present invention, the lubrication roller includes a sliding-assisting column, which is rotatably connected in a rotating groove. A plurality of groups of accommodating grooves are provided at the outer end of the sliding-assisting column. A magnetic sheet is fixedly connected to the inner wall of the accommodating groove. The lubrication roller is rotatably connected to the sliding-assisting column, and the lubrication ball is adsorbed by the magnetic sheet to ensure that the lubrication ball can be effectively retained in the accommodating groove. When the guide rail slides, the rotation of the sliding-assisting column can crush the lubrication ball to achieve a self-lubricating effect, thereby reducing the friction coefficient and extending the service life of the guide rail and the guide shoe.

[0010] As a further improvement of the present invention, the lubricating roller further comprises a plurality of groups of through holes, the plurality of groups of through holes are provided inside the slide-assisting column, a plurality of flow slots are provided in the middle of the slide-assisting column, and the plurality of groups of through holes are respectively connected with the plurality of groups of receiving slots and the plurality of flow slots, and the friction noise between the guide rail and the guide shoe can be absorbed by the plurality of groups of through holes and the flow slots in the lubricating roller, and the noise is reduced by diffusing it into the flow slots. This helps to reduce the noise generated during the operation of the elevator and improve the user experience.

[0011] As a further improvement of the present invention, the lubricating ball includes a crushing capsule, which is arranged in a storage box. The crushing capsule is filled with lubricant and magnetic particles respectively. By filling the lubricant and magnetic particles in the crushing capsule and rupturing the crushing capsule when squeezed, the lubricant is released, thereby reducing the friction between the guide rail and the guide shoe. At the same time, the presence of the magnetic particles helps to improve the lubrication effect.

[0012] As a further improvement of the present invention, the filling box includes a heat-conducting box, which is fixedly connected to one end of the storage box close to the lubrication roller. A pair of thermal shift strips are fixedly connected to the upper end of the heat-conducting box. A thermal shift strip is provided with a heat-conducting wire inside the thermal shift strip. The thermal shift strip is made of wax material. The filling box absorbs the heat generated by the friction between the guide rail and the guide shoe through the heat-conducting box, and transfers the heat to the thermal shift strip, ensuring that the stability of the lubrication system is not affected in a high temperature environment. The thermal shift strip is made of wax material. After the thermal shift strip is softened, the lubrication ball can be adsorbed by the magnetic suction sheet to prevent the lubrication ball from falling out when it softens prematurely, thereby ensuring the effective use of the lubrication ball.

[0013] As a further improvement of the present invention, a movable groove is provided on the inner wall of the placement groove, a movable plate is slidably connected to the movable groove, a limiting groove is provided on the inner wall of the movable groove, a limiting block is slidably connected to the limiting groove, and the limiting block is fixedly connected to the movable plate, a return spring is fixedly connected to the lower end of the limit block, and the return spring is fixedly connected to the inner wall of the limit groove; through the cooperation of the movable groove and the limit block, the storage box can be firmly placed in the placement groove to prevent falling off or shifting; the action of the return spring enables the limit block to automatically recover after the external force is released, thereby ensuring the reliability and stability of the structure operation, and also providing convenience for the maintenance and replacement of the storage box.

[0014] As a further improvement of the present invention, the storage box is fixedly connected to a hand-pull block at one end away from the lubrication roller, and the movable plate is provided with a hidden groove matching the hand-pull block at one end close to the storage box. The hand-pull block is provided to facilitate the operator to pull out the storage box from the placement groove to replace or replenish the lubrication ball. The setting of the hidden groove avoids the hand-pull block from being exposed during use, making the appearance of the equipment more tidy, while improving the convenience and safety of operation.

[0015] As a further improvement of the present invention, the movable plate is fixedly connected to an auxiliary pad at one end away from the storage box, and a plurality of raised strips are fixedly connected to the surface of the auxiliary pad. The arrangement of the auxiliary pad and the raised strips increases the friction between the movable plate and the storage box, so that during operation, the user can easily apply the necessary force. This arrangement not only makes the movable plate more stable when moving, but also improves the working efficiency of the overall structure.

[0016] As a further improvement of the present invention, a pair of adjustment grooves are provided at the front end of the shoe seat, and an adjusting screw block is slidably connected in the adjusting groove, and the pair of adjusting screw blocks are respectively fixedly connected to a pair of guide shoe plates, and a bidirectional screw is rotatably connected to the side end of the shoe seat, and the bidirectional screw passes through the shoe seat and is screwed to the pair of adjusting screw blocks. Through the cooperation of the adjusting groove and the adjusting screw block, the spacing between the guide shoe plates can be conveniently adjusted to adapt to guide rails of different specifications. This makes the elevator guide shoe system highly adaptable and can be widely used in elevator guide rail systems of different models, while ensuring the fit and stability of the guide shoes.

[0017] As a further improvement of the present invention, the crushing capsule is made of polytetrafluoroethylene, and the magnetic particles are made of nickel material. The crushing capsule is made of polytetrafluoroethylene material, has high temperature resistance, can be used in a high temperature environment and withstand a certain impact, ensuring that it can still work normally under high load conditions, and the magnetic particles are made of nickel material, which can be oxidized in a high temperature and humid environment, further preventing the magnetic particles from affecting the lubrication effect of the system. The oxidized particles are separated from the magnetic suction sheet of the receiving groove, which helps to maintain the durability and stability of the lubrication effect.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] This solution can not only reduce the friction coefficient between the guide shoe and the guide rail, but also reduce the noise generated by the lubrication roller when it rotates with the elevator guide rail. The heat generated by the sliding friction between the guide rail and the guide shoe can soften the thermal shift bar, and the lubrication roller can absorb multiple lubrication balls from the heat conduction box during rotation, and rupture under the squeezing of the guide rail, so that the lubricant flows out to lubricate the guide rail and the guide shoe, which not only reduces the wear of the guide rail and the guide shoe, but also improves the smoothness and stability of the elevator lifting. During the rotation of the lubrication roller, the noise generated by the friction is absorbed and transmitted to the circulation groove by multiple groups of serial holes, thereby weakening the noise and effectively reducing the noise.

[0030] An implementation of the present application is described in detail below with reference to the accompanying drawings.

[0031] Example:

[0032] See also Figure 1-7 A self-lubricating elevator guide shoe structure comprises a shoe seat 1, a plurality of lubricating rollers 3 and a plurality of lubricating balls 5. A pair of guide shoe plates 2 are fixedly mounted on the front end of the shoe seat 1. A plurality of rotation grooves are opened at one end of the pair of guide shoe plates 2 close to each other. The plurality of lubricating rollers 3 are rotatably connected in the plurality of rotation grooves respectively. A pair of guide shoe plates 2 are opened at one end away from each other. A plurality of placement grooves are opened, and the plurality of placement grooves are respectively connected to the plurality of rotation grooves. A storage box 4 is slidably connected in the placement groove. The plurality of lubricating balls 5 are all arranged in the storage box 4. A filling box 6 is fixedly connected at one end of the storage box 4 close to the lubricating roller 3. The filling box 6 is entered through the lubricating balls 5. When the lubricating roller 3 is rotated by sliding the guide rail, the plurality of lubricating balls 5 in the filling box 6 are adsorbed on their outer ends. The plurality of lubricating balls 5 are squeezed by the elevator guide rail, so that the lubricating balls 5 are broken by force to lubricate the guide shoe and the guide rail.

[0033] The lubricating roller 3 includes a sliding column 31, which is rotatably connected in the rotating groove. A plurality of accommodating grooves 32 are provided at the outer end of the sliding column 31. A magnetic sheet 33 is fixedly connected to the inner wall of the accommodating groove 32. The sliding column 31 rotates to adsorb and fix the lubricating ball 5 on the inner wall of the accommodating groove 32 with the help of the magnetic force of the magnetic sheet 33, so that the sliding column 31 is driven to rotate when the guide rail slides along the guide shoe, thereby crushing the lubricating ball 5.

[0034] The lubricating roller 3 also includes a plurality of groups of through holes 34, which are opened inside the sliding column 31. A plurality of flow grooves 35 are opened in the middle of the sliding column 31, and the plurality of groups of through holes 34 are respectively connected with the plurality of groups of accommodating grooves 32 and the plurality of flow grooves 35. The noise generated by the sliding between the guide rail and the guide shoe is absorbed and diffused into the flow groove 35 through the plurality of through holes 34, thereby achieving the effect of silencing and reducing noise.

[0035] The lubricating ball 5 includes a crushing capsule 51, which is arranged in the storage box 4. The crushing capsule 51 is filled with lubricant 52 and magnetic particles 53 respectively. The magnetic particles 53 are attracted by the magnetic attraction sheet 33, so that the lubricating ball 5 is adsorbed and fixed on the inner wall of the accommodating groove 32 as a whole. The crushing capsule 51 is squeezed and ruptured to make the lubricant 52 and the magnetic particles 53 flow out, and the lubricant 52 is used to lubricate the guide rail and the guide shoe.

[0036] The crushing capsule 51 is made of polytetrafluoroethylene, which has excellent high temperature resistance and can withstand temperatures as high as 260°C. Although it usually has good impact resistance, it will still rupture under strong external force when its film thickness is reduced. Therefore, when the crushing capsule 51 is squeezed by the guide rail, it can easily rupture to allow the lubricant 52 to flow out. The magnetic particles 53 are made of nickel material, which has strong magnetism and can be quickly oxidized into antimagnetic or weakly magnetic substances in a wet and high temperature environment. After the lubricant 52 flows out, the magnetic particles 53 are exposed to the air and are quickly oxidized under the action of the heat generated by the friction between the wet lubricant 52 and the guide rail and the guide shoe. The oxidized magnetic particles 53 are separated from the adsorption of the containing groove 32.

[0037] The filling box 6 includes a heat-conducting box 61, which is fixedly connected to one end of the storage box 4 close to the lubrication roller 3. A pair of thermal shift bars 62 are fixedly connected to the upper end of the heat-conducting box 61. The thermal shift bars 62 are provided with heat-conducting wires inside. The thermal shift bars 62 are made of wax material. The heat generated by the friction between the guide rail and the guide shoe is absorbed by the heat-conducting box 61 and transferred to the thermal shift bars 62, so that the thermal shift bars 62 are softened under the action of the heat-conducting wires. Before the thermal shift bars 62 are softened, the lubrication balls 5 can be blocked to prevent them from being adsorbed by the magnetic suction sheet 33. After the thermal shift bars 62 are softened, the lubrication balls 5 can easily pass through and be adsorbed by the magnetic suction sheet 33.

[0038] A movable groove 7 is provided on the inner wall of the placement groove, and a movable plate 8 is slidably connected in the movable groove 7. A limiting groove is provided on the inner wall of the movable groove 7, and a limiting block 9 is slidably connected in the limiting groove, and the limiting block 9 is fixedly connected to the movable plate 8. A return spring 10 is fixedly connected to the lower end of the limit block 9, and the return spring 10 is fixedly connected to the inner wall of the limit groove. The limit block 9 is pushed by the elastic force of the return spring 10, so that the movable plate 8 is pressed against the inner wall of the placement groove to block the storage box 4 and prevent the storage box 4 from leaving the placement groove. When a downward force is applied to the movable plate 8, the limit block 9 compresses the return spring 10. After the force is separated, the movable plate 8 can be driven to return to slide under the rebound force of the return spring 10.

[0039] The storage box 4 is fixedly connected to a hand-pull block 11 at one end away from the lubrication roller 3, and a hidden groove 12 matching the hand-pull block 11 is opened at one end of the movable plate 8 close to the storage box 4. The storage box 4 can be easily pulled out of the placement groove through the hand-pull block 11, and the hidden groove 12 can accommodate and hide the hand-pull block 11.

[0040] An auxiliary pad 13 is fixedly connected to one end of the movable plate 8 away from the storage box 4, and a plurality of raised strips are fixedly connected to the surface of the auxiliary pad 13. The auxiliary pad 13 can be used to conveniently apply force to the movable plate 8 to slide downward, and the friction force can be increased by using a plurality of raised strips.

[0041] A pair of adjusting grooves 14 are provided at the front end of the shoe seat 1, and an adjusting screw block 15 is slidably connected in the adjusting groove 14, and the pair of adjusting screw blocks 15 are respectively fixedly connected to a pair of guide shoe plates 2. A bidirectional screw rod 16 is rotatably connected to the side end of the shoe seat 1, and the bidirectional screw rod 16 penetrates the shoe seat 1 and is screwed to the pair of adjusting screw blocks 15. By twisting the bidirectional screw rod 16, the pair of adjusting screw blocks 15 are moved closer to each other, so as to adjust the distance between the pair of guide shoe plates 2, so that the overall guide shoe can adapt to guide rails of different sizes and can also fit the corresponding guide rails.

[0042] Working principle:

[0043] When heat is generated by friction between the elevator guide rail and the elevator guide shoe, the heat conduction box 61 absorbs the heat and transfers it to the thermal shift bar 62, causing the thermal shift bar 62 to soften due to the heat. Then, the lubricating roller 3 rotates under the sliding action of the guide rail, and the multiple groups of magnetic suction plates 33 at the outer end of the lubricating roller 3 are used to adsorb the lubricating ball 5 in the filling box 6 until the lubricating ball 5 rotates and contacts the guide rail. After being squeezed by the guide rail, the crushing capsule 51 ruptures and the lubricant 52 flows out for lubrication. Under normal working conditions, the lubricating roller 3 can not only reduce the friction coefficient, but also use multiple groups of serial holes 34 to absorb or weaken the noise generated by friction, thereby achieving the effect of reducing noise. Finally, when filling the lubricating ball 5, a downward force is applied to the movable plate 8 by resisting the auxiliary pad 13, and the storage box 4 is pulled out for filling by the hand pull block 11 and then reinstalled.

[0044] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0045] The present invention can reduce the friction coefficient between the guide shoe and the guide rail and the noise generated by the lubricating roller 3 rotating as it slides along the elevator guide rail. The heat generated by the sliding friction between the guide rail and the guide shoe softens the thermal shift bar 62. The lubricating roller 3 can absorb a plurality of lubricating balls 5 from the heat conduction box 61 during rotation, and break under the squeeze of the guide rail, so that the lubricant 52 flows out to lubricate the guide rail and the guide shoe, which not only reduces the wear of the guide rail and the guide shoe, but also improves the smoothness and stability of the elevator lifting. During the rotation of the lubricating roller 3, the noise generated by the friction is absorbed and transmitted to the flow groove 35 by multiple groups of serial holes, so as to weaken the noise, thereby effectively reducing the noise.
