Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an elevator traction rope tension regulating device. Background Art

[0002] An elevator hoist rope is a specialized steel wire rope that connects the car and counterweight. It relies on friction with the traction sheave groove to drive the car up and down. The hoist rope is a critical component in the elevator's transmission system, ensuring the proper operation and safety of the elevator. The hoist rope is connected to the main drive unit via the traction unit, which, through suspension, drives the wire rope, causing the car and counterweight to move in opposite directions, thereby achieving the elevator's lifting and lowering functions. The hoist rope relies on friction in the traction sheave groove to transmit power, ensuring smooth elevator operation. The hoist rope is typically made of high-strength steel wire rope with excellent wear resistance and tensile strength. Its structure consists of multiple strands of steel wire wound together, which are then combined into a single rope. This structure not only enhances the rope's strength and durability, but also ensures stability and safety during elevator operation. Rope maintenance and inspection are key to ensuring safe elevator operation. Regular inspection of the hoist rope for wear, lubrication, and signs of breakage or damage is crucial. An elevator rope tension adjustment device is required during use.

[0003] In this regard, China has applied for patent number CN115611116A, which discloses an elevator traction rope tension adjustment device and adjustment method, belonging to the field of elevator traction ropes. The present invention includes a traction rope, a car, a traction sheave, a pulley, and a counterweight. There are four traction ropes, each of which is provided with a first adjustment mechanism for adjusting the tension of a single traction rope. The top of the car is provided with a second adjustment mechanism for simultaneously adjusting the tension of the four traction ropes. The traction ropes pass through the second adjustment mechanism, the traction sheave, the pulley, and the counterweight in sequence. The present invention solves the problem of the inability to adjust the traction rope in the prior art. By changing the position of the rope shaft, the tension of the traction rope that fits the rope shaft can be adjusted. The reciprocating screw driven by the drive motor can move the pulley horizontally to achieve the purpose of adjusting the traction rope tension. The cylinder causes the cross support arm to drive the second adjustment mechanism to rise and fall, thereby changing the distance from the rope end above the traction rope, thereby achieving the purpose of adjusting the traction rope tension.

[0004] However, when the elevator traction rope tension adjustment device is in use, the existing structure cannot adjust the tension of the traction rope at will. The existing device can adjust the tension of the traction rope that fits the rope shaft by changing the position of the rope shaft, but cannot adjust the tension on the traction rope as needed. Therefore, it is impossible to simply adjust the tension of the traction rope as needed, thereby reducing the practicality of the device.

[0005] Therefore, in order to solve the above problems, an elevator traction rope tension adjustment device is proposed. Summary of the Invention

The existing device can adjust the tension of the traction rope that fits the rope shaft by changing the position of the rope shaft, but cannot adjust the tension on the traction rope as needed, and thus cannot simply adjust the tension of the traction rope as needed, thereby reducing the practicality of the device.

[0007] The cam is secured to the upper end of the cam and secured to the lower end of the cam, and the cam is secured to the lower end of the cam. The buffering work is carried out by driving the first limit sleeve through the hydraulic rod in the mechanism, and the first limit sleeve is limited by the limit bolt, and the second limit sleeve is moved by the first limit bolt, thereby contracting the spring.

One end of the traction rope is passed through the slide groove on the protrusion on the fixed plate in the mechanism, and the traction rope is clamped by driving the arc plate at one end through the cross plate. Due to the height difference between the protrusion and the fixed plate, the height difference can be used to lock the traction rope, and then the threaded cap on one side is rotated on the threaded rod, thereby moving the clamping plate on the threaded rod, so that the clamping plate is fitted with the fixed plate, thereby limiting and fixing the arc plate, and then adjusting the tension of the traction rope.
