Description

Technical Field

[0001] This application relates to the field of elevator maintenance auxiliary equipment, and in particular to an auxiliary device for replacing elevator steel cables. Background Technology

[0002] Elevator cables are a critical component of elevator systems, typically composed of multiple high-strength steel wires twisted together, usually with a fiber or metal core for support and cushioning. The outer layer of the steel wires is usually treated with galvanizing or other anti-corrosion methods to improve their corrosion and abrasion resistance. The primary function of elevator cables is to bear the weight of the elevator car, passengers, goods, and counterweight. Through the combined action of multiple cables, this weight is evenly distributed on the traction sheave, ensuring the safe and stable operation of the elevator.

[0003] Because elevator cables are under constant load, they inevitably experience broken wires and wear over time. To ensure the safe operation of the elevator, the cables need to be replaced when broken wires or wear reach a certain standard, which requires the use of various auxiliary devices.

[0004] Rope release devices are commonly used auxiliary equipment in elevator cable replacement operations. When replacing elevator cables, the rope release device neatly releases the new cable, preventing it from becoming tangled and messy on the ground, facilitating operation for workers, and improving the efficiency of cable replacement. However, existing rope release devices, designed for easy storage and cost savings, suffer from poor structural stability and short service life. Utility Model Content

[0005] The main purpose of this application is to propose an auxiliary device for replacing elevator steel cables, which aims to solve the problem of poor structural stability of existing rope release devices.

[0006] To achieve the above objectives, the elevator cable replacement auxiliary device proposed in this application includes: a support assembly and a rotating assembly, wherein the rotating assembly is rotatably mounted on the support assembly, and the rotating assembly is used to place a coiled steel cable.

[0007] The rotating assembly includes a telescopic rod, with several bearing rods and several connecting rods arranged circumferentially on the outer side of the telescopic rod. The first end of the bearing rod is rotatably connected to the first end of the telescopic rod, the first end of the connecting rod is rotatably connected to the corresponding bearing rod, and the second end of the connecting rod is rotatably connected to the second end of the telescopic rod. The telescopic rod is used to extend or shorten the distance between the first end and the second end.

[0008] Optionally, the telescopic rod includes a fixed cylinder and a movable rod. The first end of the fixed cylinder is rotatably mounted on the support assembly. The movable rod is slidably disposed inside the fixed cylinder and extends out from the second end. A spring is also disposed inside the fixed cylinder, with the two ends of the spring abutting against the inner wall of the fixed cylinder and the movable rod, respectively.

[0009] Optionally, the support assembly includes a support block, and a plurality of support rods are evenly arranged on the outer circumference of the support block. The first end of each support rod is rotatably mounted on the support block, and the range of rotation of the support rod is 0°-90°.

[0010] Optionally, a limiting groove is provided on the support block corresponding to the support rod, and the first end of the support rod is rotatably installed in the corresponding limiting groove.

[0011] Optionally, an anti-slip block is fixedly installed on the second end of the support rod, the anti-slip block being used to contact the ground.

[0012] Optionally, the first end of the telescopic rod is rotatably mounted on the support block, and a locking structure is provided between the telescopic rod and the support block to prevent the rotating assembly from rotating.

[0013] Optionally, the locking structure includes a locking groove and a locking block. A cavity is formed inside the support block corresponding to the axis of the telescopic rod. The locking groove is formed on the downward-facing surface of the cavity. The locking block is disposed in the cavity. A control rod is disposed through the telescopic rod. The control rod is splinedly connected to the telescopic rod. The first end of the control rod is fixedly connected to the locking block. The second end of the control rod extends from the second end of the telescopic rod. Teeth are provided on the side of the locking groove and the side of the locking block. The teeth on the locking block are used to engage with the teeth in the locking groove.

[0014] Optionally, a hand-held portion is provided on the second end of the control lever.

[0015] Optionally, it also includes a conductor structure, a mounting rod and a guide ring, wherein the mounting rod is sequentially divided into a connecting part, a supporting part and a mounting part, the connecting part is rotatably connected to one of the supporting rods, the supporting part is supported on the ground, and the guide ring is fixedly installed on the mounting part, the guide ring being used for the steel cable to pass through.

[0016] Optionally, two guide wheels are arranged vertically and parallel to each other inside the guide ring, and the guide wheels are rotatably connected to the guide ring.

[0017] This application's technical solution involves setting up a support assembly and a rotating assembly. The rotating assembly is rotatably mounted on the support assembly and is used to hold a coiled steel cable. The rotating assembly includes a telescopic rod, with several load-bearing rods and several connecting rods arranged circumferentially on its outer side. The first end of each load-bearing rod is rotatably connected to the first end of the telescopic rod, the first end of each connecting rod is rotatably connected to a corresponding load-bearing rod, and the second end of each connecting rod is rotatably connected to the second end of the telescopic rod. The telescopic rod is used to extend or shorten the distance between the first and second ends. When the device needs to be moved or transported, the distance between the first and second ends is extended by the telescopic rod, thereby pulling the load-bearing rod via the connecting rod. The telescopic pole retracts to facilitate transport. In use, the telescopic pole shortens the distance between its first and second ends, which in turn pushes the supporting pole outward via the connecting rod. The coiled steel cable is then looped around the outside of the connecting rod and held in place by the supporting pole. When replacing the cable, pulling one end causes the rotating component to rotate on the support component, allowing the cable to be released smoothly. When the device is deployed, each set of supporting poles and connecting rods forms a triangular structure with the central telescopic pole. Multiple triangular structures are circumferentially distributed on the outside of the telescopic pole, collectively supporting the circular steel cable, thus enhancing the device's stability during use.

[0030] Because elevator cables are under constant load, they inevitably experience broken wires and wear over time. To ensure the safe operation of the elevator, the cables need to be replaced when broken wires or wear reach a certain standard, which requires the use of various auxiliary devices.

[0031] Rope release devices are commonly used auxiliary equipment in elevator cable replacement operations. When replacing elevator cables, the rope release device neatly releases the new cable, preventing it from becoming tangled and messy on the ground, facilitating operation for workers, and improving the efficiency of cable replacement. However, existing rope release devices, designed for easy storage and cost savings, suffer from poor structural stability and short service life.

[0032] In view of this, this application proposes an auxiliary device for replacing elevator steel cables.

[0033] In the embodiments of this application, reference is made to Figures 1 to 3The aforementioned auxiliary device for replacing elevator steel cables includes: a support assembly 2 and a rotating assembly 1. The rotating assembly 1 is rotatably mounted on the support assembly 2 and is used to hold coiled steel cables. The rotating assembly 1 includes a telescopic rod 110, with several bearing rods 120 and several connecting rods 130 arranged circumferentially on the outer side of the telescopic rod 110. The first end of the bearing rod 120 is rotatably connected to the first end of the telescopic rod 110, the first end of the connecting rod 130 is rotatably connected to the corresponding bearing rod 120, and the second end of the connecting rod 130 is rotatably connected to the second end of the telescopic rod 110. The telescopic rod 110 is used to allow the first end... The distance to the second end can be lengthened or shortened; the rotational characteristics of the rotating component 1 on the supporting component 2 are used to realize the free rotation of the steel cable reel, which facilitates the release of the steel cable; the setting of the telescopic rod 110 facilitates the pulling or pushing of the bearing rod 120 through the connecting rod 130, thereby facilitating the retraction and unfolding of the rotating component 1; in addition, when the device is unfolded, each set of bearing rods 120 and connecting rods 130 forms a triangular structure with the middle telescopic rod 110. Multiple triangular structures are circumferentially distributed on the outside of the telescopic rod 110 and jointly support the circular steel cable, making the device more stable during use.

[0034] In this embodiment, the telescopic rod 110 includes a fixed cylinder 111 and a movable rod 112. The first end of the fixed cylinder 111 is rotatably mounted on the support assembly 2. The movable rod 112 is slidably disposed inside the fixed cylinder 111 and extends out from the second end. A spring 113 is also disposed inside the fixed cylinder 111, with the two ends of the spring 113 abutting against the inner wall of the fixed cylinder 111 and the movable rod 112, respectively. When the weight of the steel cable roll acts on the telescopic rod 110, the movable rod 112 slides inside the fixed cylinder 111, compressing the spring 113. When the weight of the steel cable roll decreases, the elastic force of the spring 113 will cause the movable rod 112 to return to its original position, thereby enabling the rotating assembly 1 to automatically retract. In addition, the spring 113 can buffer the impact force generated by the steel cable roll during rotation, reduce damage to the device, and extend the service life of the device. At the same time, the elastic support of the spring 113 enables the rotating assembly 1 to better adapt to steel cable rolls of different weights, ensuring the stability and reliability of the device.

[0035] In this embodiment, the support assembly 2 includes a support block 210, and a plurality of support rods 220 are evenly arranged circumferentially on the outer side of the support block 210. The first end of each support rod 220 is rotatably mounted on the support block 210, and the range of rotation of the support rod 220 is 0°-90°. When the device is in use, the support rods 220 are rotatably mounted on the support block 210 and can rotate within the range of 0°-90°. When the support rods 220 are extended to 90°, they are perpendicular to the ground, which provides stable support for the entire device. After the device is no longer in use, the support rods 220 can be rotated back for easy transport of the device.

[0036] In this embodiment, a limiting groove 211 is provided on the support block 210 corresponding to the support rod 220. The first end of the support rod 220 is rotatably installed in the corresponding limiting groove 211. The first end of the support rod 220 rotates in the limiting groove 211. The limiting groove 211 provides a specific space and trajectory for the rotation of the support rod 220, ensuring that the support rod 220 can rotate accurately within the specified range and avoid swaying or deviation. At the same time, the limiting groove 211 can limit the rotation range of the support rod 220, ensuring that its range is between 0° and 90°, thus ensuring the stability of the support assembly 2.

[0037] In this embodiment, an anti-slip block 221 is fixedly installed on the second end of the support rod 220. The anti-slip block 221 can be a structure made of rubber material. The anti-slip block 221 is used to contact the ground. When the support rod 220 is extended and in contact with the ground, the anti-slip block 221 is tightly attached to the ground to prevent the device from sliding during operation. The anti-slip block 221 effectively improves the stability of the device on the ground, avoids the device from affecting work efficiency or causing safety accidents due to slippage during steel cable replacement, and enhances the safety of the device.

[0038] In this embodiment, the first end of the telescopic rod 110 is rotatably mounted on the support block 210. A locking structure 3 is provided between the telescopic rod 110 and the support block 210 to prevent the rotating component 1 from rotating. When it is necessary to fix the rotating component 1, the locking structure 3 is operated to prevent the rotating component 1 from rotating on the support block 210. When it is necessary to rotate the rotating component 1, the locking structure 3 is released. The locking structure 3 can fix the rotating component 1 when needed, facilitating operations such as adjusting the position of the steel cable or stopping the release of the steel cable. At the same time, the locking can be released when it is not necessary to fix it, allowing the rotating component 1 to rotate freely, improving the flexibility and practicality of the device.

[0039] In this embodiment, the locking structure 3 includes a locking groove 302 and a locking block 301. A cavity 303 is formed inside the support block 210 corresponding to the axis of the telescopic rod 110. The locking groove 302 is formed on the downward-facing surface of the cavity 303. The locking block 301 is disposed within the cavity 303. A control rod 4 is inserted through the telescopic rod 110 and splinedly connected to it. The first end of the control rod 4 is fixedly connected to the locking block 301, and the second end of the control rod 4 extends from the second end of the telescopic rod 110. The sides of the locking groove 302 and the sides of the locking block 301 are also connected. All surfaces are equipped with teeth. The teeth on the locking block 301 engage with the teeth in the locking groove 302. When locking the rotating component 1, the control lever 4 is pushed downwards, causing it to push the locking block 301 downwards into the locking groove 302. The teeth on the locking block 301 engage with the teeth in the locking groove 302, thus preventing the rotating component 1 from rotating. When unlocking, the control lever 4 is pulled, causing the locking block 301 to move upwards, disengaging the teeth and allowing the rotating component 1 to rotate freely. Locking and unlocking the rotating component 1 can be achieved simply by pulling or pushing the control lever 4. The tooth engagement provides a reliable locking effect, ensuring that the rotating component 1 will not rotate in the locked state, thus improving the safety and reliability of the device.

[0040] In this embodiment, a hand-held part 5 is provided on the second end of the control lever 4; the hand-held part 5 provides an easy part for the operator to hold and apply force, so that the operator can more easily control the movement of the control lever 4. At the same time, the device can also be carried by the hand-held part 5 for easy transport.

[0041] In this embodiment, a conductor structure is also included, comprising a conductor structure mounting rod 610 and a guide ring 620. The mounting rod 610 is sequentially divided into a connecting part 611, a supporting part 612, and a mounting part 613. The connecting part 611 is rotatably connected to one of the supporting rods 220. The supporting part 612 is supported on the ground. The guide ring 620 is fixedly mounted on the mounting part 613. The guide ring 620 is used for the steel cable to pass through. The connecting part 611 of the mounting rod 610 is rotatably connected to one of the supporting rods 220, and the position of the mounting rod 610 is adjusted so that the supporting part 612 is supported on the ground. Then, the steel cable is passed through the guide ring 620. During the steel cable replacement process, the guide ring 620 guides the steel cable, allowing it to be released in a predetermined direction. The conductor structure improves the smoothness of the steel cable replacement process, reduces the possibility of steel cable tangling, and improves work efficiency.

[0042] In this embodiment, two guide wheels 621 are arranged parallel to each other vertically inside the guide ring 620, and the guide wheels 621 are rotatably connected to the guide ring 620. When the steel cable passes through the guide ring 620, it contacts the two guide wheels 621, and the guide wheels 621 rotate as the steel cable moves. The arrangement of the guide wheels 621 reduces the friction of the steel cable when it moves inside the guide ring 620, reduces the wear of the steel cable, and extends the service life of the steel cable. At the same time, it also further improves the smoothness and efficiency of the steel cable replacement process.

[0043] This application's technical solution involves setting up a support assembly and a rotating assembly. The rotating assembly is rotatably mounted on the support assembly and is used to hold a coiled steel cable. The rotating assembly includes a telescopic rod, with several load-bearing rods and several connecting rods arranged circumferentially on its outer side. The first end of each load-bearing rod is rotatably connected to the first end of the telescopic rod, the first end of each connecting rod is rotatably connected to a corresponding load-bearing rod, and the second end of each connecting rod is rotatably connected to the second end of the telescopic rod. The telescopic rod is used to extend or shorten the distance between the first and second ends. When the device needs to be moved or transported, the distance between the first and second ends is extended by the telescopic rod, thereby pulling the load-bearing rod via the connecting rod. The telescopic pole retracts to facilitate transport. In use, the telescopic pole shortens the distance between its first and second ends, which in turn pushes the supporting pole outward via the connecting rod. The coiled steel cable is then looped around the outside of the connecting rod and held in place by the supporting pole. When replacing the cable, pulling one end causes the rotating component to rotate on the support component, allowing the cable to be released smoothly. When the device is deployed, each set of supporting poles and connecting rods forms a triangular structure with the central telescopic pole. Multiple triangular structures are circumferentially distributed on the outside of the telescopic pole, collectively supporting the circular steel cable, thus enhancing the device's stability during use.
