Description

Technical Field

[0001] This utility model relates to the field of elevator maintenance tools, and in particular to a wire rope length adjustment device. Background Technology

[0002] With the rapid development of China's economy, the improvement of urbanization and people's living standards, elevators, as vertical transportation tools in residential buildings, office buildings, and other buildings, have become an indispensable part of our daily lives, just like other modes of transportation. The number of elevators in use nationwide and their annual growth rate have continued to increase year by year.

[0003] Because elevator speed governor wire ropes have a long service life, they tend to stretch and become longer over time, requiring adjustment and maintenance. The traditional adjustment method requires two people: one to hold the wire rope while the other adjusts the rope end. Due to the weight of the wire rope and the presence of a lot of oil, the manual pulling force is unstable, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a wire rope length adjustment device, which solves the problem that the manual pulling force is unstable and poses a safety hazard due to the weight of the wire rope and the presence of a lot of oil.

[0005] To achieve the above objectives, this utility model provides a wire rope length adjustment device, including a rope clamp, a chain, a first chain hook, and a second chain hook. The first chain hook is connected between the rope clamp and the chain, and the second chain hook is installed at the end of the chain away from the rope clamp.

[0006] The rope clamp includes a mounting handle, a first mounting block, a movable block, and a second mounting block. One end of the mounting handle is provided with a mounting ring. The first chain hook is connected between the mounting ring and the chain. The first mounting block is mounted on the end of the mounting handle away from the mounting ring via a first connecting part. One end of the movable block is sleeved on the outer wall of the mounting handle. One end of the second mounting block is fixedly connected to the movable block. The other end of the second mounting block is mounted on the end of the first mounting block away from the first connecting part via a second connecting part.

[0007] The rope clamp further includes a first anti-slip tooth and a second anti-slip tooth. The first anti-slip tooth is fixedly connected to the first mounting block and is located on the outer side wall of the first mounting block. The second anti-slip tooth is fixedly connected to the second mounting block and is located on the outer side wall of the second mounting block.

[0008] The chain includes multiple chain links and auxiliary components. The chain links are interconnected by welding, and the auxiliary components are sleeved on the outer wall of the chain links.

[0009] The auxiliary components include a mounting sleeve, a mounting band, a hook surface, and a rough surface. The mounting sleeve is fitted onto the outer wall of the chain link. The mounting band is fixedly connected to the mounting sleeve and located on the outer wall of the mounting sleeve. The hook surface and the rough surface are arranged opposite each other on both sides of the mounting band.

[0010] This utility model discloses a wire rope length adjustment device. When adjusting and maintaining the wire rope of an elevator speed governor, the wire rope is clamped by the rope clamp, and the chain is wound around the car top guardrail. When the wire rope is pulled down, the tensioning device raises the wire rope under tension. When the target height is reached, the chain is hooked by the second chain hook, forming a stable tension. This replaces the worker's continuous pulling of the rope, avoiding the risk of slippage caused by direct manual pulling. The self-locking structure ensures stable tension, reduces potential accidents, and solves the problem that the heavy weight and oil contamination of the wire rope cause unstable manual pulling force and safety hazards.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a schematic diagram of the overall structure of this utility model. Figure 3 This is a structural schematic diagram of the rope clamp of this utility model. Figure 4 This is a schematic diagram of the chain link and auxiliary components of this utility model.

[0019] This utility model provides a wire rope length adjustment device, including a rope clamp 1, a chain 2, a first chain hook 3, and a second chain hook 4. The rope clamp 1 includes a mounting handle 101, a first mounting block 102, a movable block 103, a second mounting block 104, a first anti-slip tooth 108, and a second anti-slip tooth 109. The chain 2 includes multiple chain links 201 and auxiliary components. The auxiliary components include a mounting sleeve 202, a mounting strap 203, a hook surface 204, and a rough surface 205. The above structure solves the problem that the manual pulling force is unstable and poses a safety hazard due to the weight of the wire rope 5 and the presence of a lot of oil.

[0020] In a specific implementation, the first chain hook 3 is connected between the rope clamp 1 and the chain 2, and the second chain hook 4 is installed at the end of the chain 2 away from the rope clamp 1. When adjusting and maintaining the elevator speed governor wire rope 5, after clamping the wire rope 5 tightly with the rope clamp 1, the chain 2 is wrapped around the car top guardrail 6. When the wire rope 5 is pulled down, the tensioning device of the wire rope 5 is raised after being stressed. When the target height is reached, the second chain hook 4 hooks the chain 2 to form a stable tension, which replaces the worker in continuously pulling the rope and avoids the risk of slippage caused by direct manual pulling of the rope. The self-locking structure ensures stable tension, reduces accident hazards, and solves the problem that the manual pulling force is unstable and poses safety hazards due to the weight of the wire rope 5 and the presence of a lot of oil.

[0021] The mounting handle 101 has a mounting ring 105 at one end. The first chain hook 3 is connected between the mounting ring 105 and the chain 2. The first mounting block 102 is mounted on the end of the mounting handle 101 away from the mounting ring 105 via a first connecting part 106. One end of the movable block 103 is sleeved on the outer wall of the mounting handle 101. One end of the second mounting block 104 is fixedly connected to the movable block 103. The other end of the second mounting block 104 is mounted on the first mounting block 102 away from the mounting ring 105 via a second connecting part 107. When clamping the wire rope 5 at one end of the first connecting part 106, the rope clamp 1 is brought close to the wire rope 5, so that the wire rope 5 is between the first mounting block 102 and the second mounting block 104. The mounting handle 101 is pulled down, and the first mounting block 102 moves closer to the second mounting block 104. The wire rope 5 is fixedly connected by the first mounting block 102 and the second mounting block 104. At the same time, the greater the pulling force on the mounting handle 101, the tighter the first mounting block 102 and the second mounting block 104 clamp the wire rope 5.

[0022] The first anti-slip tooth 108 is fixedly connected to the first mounting block 102 and located on the outer side wall of the first mounting block 102. The second anti-slip tooth 109 is fixedly connected to the second mounting block 104 and located on the outer side wall of the second mounting block 104. When the mounting handle 101 is pulled down, the first mounting block 102 drives the first anti-slip tooth 108 to move towards the second anti-slip tooth 109 until the first anti-slip tooth 108 and the second anti-slip tooth 109 are in close contact with the wire rope 5. When the teeth on the first anti-slip tooth 108 and the second anti-slip tooth 109 come into contact with the wire rope 5, they can embed into the surface of the wire rope 5, significantly increasing the friction between the rope clamp 1 and the wire rope 5, and avoiding safety accidents caused by the slippage of the wire rope 5.

[0023] The chain links 201 are interconnected by welding, and the auxiliary component is sleeved on the outer wall of the chain links 201. The chain links 201 are welded together to form a chain 2, and the auxiliary component is used to house the chain 2.

[0024] The mounting sleeve 202 is fitted onto the outer wall of the chain link 201. The mounting strap 203 is fixedly connected to the mounting sleeve 202 and located on the outer wall of the mounting sleeve 202. The hook surface 204 and the rough surface 205 are arranged opposite each other on both sides of the mounting strap 203. After adjustment, the chain 2 is tidied up, and the mounting strap 203 is wrapped around the chain 2 so that the hook surface 204 contacts the rough surface 205, thereby binding the chain 2, preventing the chain 2 from scattering, and facilitating user recycling.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
