Description

Technical Field

[0001] This invention relates to the field of wire rope tension adjustment, and more particularly to a wire rope tension adaptive device. Background Technology

[0002] After an elevator is installed and put into use, uneven tension will occur in the wire ropes due to stretching and deformation. This necessitates regular inspection using a tension meter to check the tension of each wire rope and then adjust the spring force of the rope end assembly. However, current routine maintenance does not include this requirement, and maintenance companies may not possess wire rope tension meters. Long-term uneven wire rope tension can easily lead to increased vibration and noise, abnormal wear of the rope grooves and wire ropes, significantly reducing performance and lifespan.

[0003] Chinese patent document CN105540385A discloses an "automatic tension adjustment system for elevator wire ropes." It includes several cylinders, each housing a piston. Each piston is fixedly connected to the tail end pull rod of an elevator wire rope and can move freely within the cylinder. Each piston and its cylinder form an internal cavity, and all cavities are interconnected and filled with a pressure-transmitting liquid, forming a closed, interconnected liquid system. The tension of the wire rope acts on the piston through the tail end pull rod, and the piston exerts a certain pressure on the liquid in the internal cavity. Because all the cylinder cavities are interconnected, based on the principle that liquid can transmit pressure in all directions without changing magnitude, the liquid pressure in the different connected cavities eventually reaches a dynamic equilibrium, making the force exerted by the liquid on the different pistons the same, thus achieving automatic adjustment of the tension of all wire ropes. However, this adjustment device is located at the end of the traction rope, and the tension adjustment is mainly along the extension direction of the wire rope. Therefore, the adjustment response time is long, the adjustment speed is slow, and the cost is high. Summary of the Invention

[0004] This invention primarily addresses the technical problems of poor tension adjustment effect and high adjustment cost of existing wire rope systems. It provides a wire rope tension adaptive device, in which a hydraulic device and a fixing rod on the anti-derailment body cooperate to form a hole. The wire rope passes through the limiting rod on the hydraulic device and the hole, and is tightened by the limiting rod. When the tension of several wire ropes changes, it causes the fixing rod to move horizontally, changing the hydraulic pressure in the corresponding hydraulic chamber. Multiple hydraulic chambers within the hydraulic device adjust each other, causing the remaining fixing rods to adjust their tension and change the tension of other wire ropes, thus stabilizing the tension of the entire wire rope and ensuring the safe operation of the elevator.

[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: The present invention includes a hydraulic device and an anti-derailment body. The hydraulic device and the anti-derailment body are equipped with fixed rods. The hydraulic device and the anti-derailment body are connected. The hydraulic device is equipped with a limiting rod, and the wire rope passes between the limiting rod and the fixed rod. Conventional wire rope tension adjustment devices are installed at the ends of the wire ropes in the elevator shaft. When the tension of the wire rope changes, the length of the wire rope changes, and the wire rope pulls the corresponding wire rope fixing rod of the hydraulic device. The movement of each fixing rod causes a change in the hydraulic pressure within the corresponding cavity of the hydraulic device. The hydraulic pressure within the hydraulic device remains constant, thus automatically adjusting the hydraulic pressure in different cavities. The hydraulic pressure adjusts the movement of different fixing rods in the opposite direction to adjust the tension of different wire ropes, ensuring that the overall tension of the entire wire rope remains stable and preventing the collapse of a single wire rope due to excessive tension, which would affect the operation of the entire elevator. However, elevator wire ropes are relatively long. Traditional wire rope tension adjustment devices adjust tension by stretching the wire rope at its end and along its direction. This results in a long response time for tension changes to be transmitted to the corresponding position, requires significant force for adjustment, and the adjustment effect is not very good. The wire rope tension adjustment device of this patent is installed near the end of the wire rope in the hoistway. A fixing rod is installed at the bend of the wire rope; one fixing rod is connected to a hydraulic device, and the other is connected to an anti-derailment body. Limiting rods are provided at both ends of the hydraulic device to fix the passing wire rope. The fixing rods are installed perpendicular to the wire rope. When the wire rope tension changes, the fixing rods adjust the tension of different wire ropes vertically through hydraulic balance within the hydraulic device, maintaining the overall tension stability of the entire wire rope bundle and ensuring the normal operation of the elevator.

[0006] Preferably, the hydraulic device has a limit rod mounting component at its top, and the limit rod is mounted on the limit rod mounting component. A slot is provided between the limit rod mounting component and the limit rod. Limit rod mounting components are provided at both the top and bottom of the hydraulic device. The longitudinal bars at both ends of the limit rod mounting component fix the two ends of the limit rod. The wire rope passes through the slot between the limit rod and the limit rod mounting component, forming an angle. An angle is also formed in the middle of the fixed rod. The angle at the fixed rod and the angle at the slot are in opposite directions. This method can taut the wire rope, ensuring that the fixed rod can stably adjust the tension of the wire rope in the vertical direction.

[0007] Preferably, the anti-detachment body is equipped with an anti-detachment main plate, and anti-detachment connecting rods are provided on both sides of the anti-detachment main plate. Several No. 1 steel wire rope fixing rods are provided at the center of the anti-detachment main plate. The anti-detachment body is connected to the hydraulic device through the anti-detachment connecting rods on both sides, so that the fixing rods on the anti-detachment main plate and the fixing rods on the hydraulic device fix the steel wire rope from two directions perpendicular to the steel wire rope. After the fixing rods on both sides are connected to each other, they can lock the steel wire rope while also adjusting the tension of the steel wire rope in the vertical direction.

[0008] Preferably, the hydraulic device has several No. 2 wire rope fixing rods on its side. Each No. 2 wire rope fixing rod includes a No. 2 fixing rod connector and a rod body. The No. 2 fixing rod connector is located at one end of the rod body, and the other end of the rod body is connected to the side of the hydraulic device. The No. 2 fixing rod connector has a notch in the middle, the size of which is slightly larger than the diameter of the wire rope. The notch has flat surfaces on both sides. The hydraulic device and the anti-derailment main board have corresponding No. 2 wire rope fixing rods. The No. 2 fixing rod connector on the No. 2 wire rope fixing rod is U-shaped, with a semi-circular notch in the middle and flat surfaces on both sides of the notch. This corresponds to the flat surfaces on the fixing rod connector on the anti-derailment main board, allowing the two fixing rods to fit tightly together. The diameter of the notch is slightly larger than the diameter of the wire rope. The fixing rod notch can both hold the wire rope in place to a certain extent and allow the wire rope some relative movement within the notch. Over-tightening the wire rope can cause it to break due to excessive tension when controlled by the fixing rod, affecting the normal operation of the elevator.

[0009] Preferably, the first wire rope fixing rod includes a rod body and a first fixing rod connector. One end of the rod body is equipped with a spring, and the first fixing rod connector is located at the spring-loaded end of the rod body and connected to the spring. The other end of the rod body is connected to one side of the anti-derailment main board. A spring is installed between the rod body and the first fixing rod connector of the first wire rope fixing rod on the anti-derailment main board. When the first wire rope fixing rod moves the wire rope, it will be subjected to the compressive force of the wire rope. The spring can alleviate the compressive force received by the first fixing rod connector, extending its service life and durability.

[0010] Preferably, the two surfaces connected to the side of the second wire rope fixing rod are provided with connecting rod slots. Each connecting rod slot has a central slot, the size of which is adapted to the size of the anti-derailment connecting rod. The orientation of the central slot is the same as that of the second wire rope fixing rod. A corresponding locking device is provided within the central slot, allowing the connecting rod on the anti-derailment body to be easily installed into the central slot. After installation, the connecting rod can perform a small range of extension and retraction within the central slot, ensuring that the connecting rod is not damaged due to excessive force when adjusting the wire rope.

[0011] Preferably, the No. 1 and No. 2 fixing rod joints are sized to form a hole, the size of which is slightly larger than the diameter of the wire rope, and the bend of the wire rope is fixed in the hole. The No. 1 and No. 2 fixing rod joints are identical in size and shape, both U-shaped, with a notch in the middle and flat surfaces on both sides of the notch. During installation, the flat surfaces of the No. 1 and No. 2 fixing rod joints are joined together to form a hole with a diameter slightly larger than the cross-sectional diameter of the wire rope. This hole allows the wire rope to be fixed while also ensuring some room for movement.

[0012] Preferably, the angled steel wire rope at the splicing hole of the first and second fixed rod joints is subjected to forces in three directions: the force F acting on the upper end of the steel wire rope towards the limiting rod, the force F acting on the lower end of the steel wire rope towards the lower limiting rod, and the force Ft acting on the horizontal direction at the angle of the steel wire rope. The angle between one side of the steel wire rope and the horizontal force is α. F1 = Ft / (2*cos(α)), F2 = Ft / (2*cos(α)), Ft = (F1+F2)*cos(α). The force magnitude of the steel wire rope at different bending angles can be calculated using existing steel wire rope force formulas. Changing the height of the limiting rod can change the bending angle of the steel wire rope. Based on the actual force range of the steel wire rope during elevator operation, the most suitable limiting rod height can be selected for manufacturing, improving the service life of the adjustment device and ensuring the daily operational safety of the steel wire rope.

[0013] The beneficial effects of this invention are:

[0014] 1. This invention is installed vertically on the wire rope for lateral tension adjustment, which can more directly and effectively regulate the tension changes of the wire rope.

[0015] 2. This device can balance the tension of the wire rope, reduce damage to components caused by concentrated stress on the wire rope, and improve the service life of elevator components.

[0016] 3. It can effectively alleviate the vibration of the wire rope, reduce the vibration noise transmitted by the wire rope in the elevator, and improve the comfort of the elevator ride.

[0017] 4. No need for elevator maintenance personnel to regularly check and adjust the tension of the steel wire rope. The structure is simple and small in size, with strong applicability, making it convenient for new and old elevators to be retrofitted, thus reducing elevator maintenance costs.

Detailed Implementation

[0025] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0026] Example: This example describes a wire rope tension adaptive device, such as... Figure 1As shown, the main body of this device consists of a hydraulic device 2 and an anti-detachment body 3. The hydraulic device 2 and the anti-detachment body 3 are spliced ​​and fixed by corresponding anti-detachment connecting rods 3.2 and connecting rod slots 2.2. Both the hydraulic device 2 and the anti-detachment body 3 are equipped with several fixing rods, and each fixing rod connected to the hydraulic device 2 has a corresponding hydraulic cavity within the hydraulic device. The fixing rods on both sides are spliced ​​together. Limiting rod mounting components are provided at the top and bottom of the hydraulic device 2. The limiting rod mounting components include two columns and a base connecting the two columns. The base is installed on the top and bottom of the hydraulic device 2. The two ends of the limiting rod 4 are respectively connected to the two columns of the limiting rod mounting component, forming a slot between the two columns of the limiting rod mounting component and the limiting rod 4. When the wire rope is installed on the adaptive device, wire rope 1 passes through the slot between the limit rod 4 at the upper end of the hydraulic device 2 and the limit rod mounting piece. Wire rope 1 is below the limit rod, then passes between the fixed rods, and finally passes through the slot between the limit rod 4 at the lower end of the hydraulic device and the limit rod mounting piece. Wire rope 1 is located above the limit rod 4. Common wire rope tension adaptive devices are all located at the end of the wire rope, and the tension adjustment method is mainly to stretch the wire rope along its direction. However, the length of the elevator shaft is very large, and the end of the wire rope is fixed at the bottom or top of the shaft. Because the wire rope on the elevator is very long, stretching the end of the wire rope to adjust the tension of the wire rope near the elevator would make this adjustment method much slower and would require a lot of pulling force to stretch the wire rope, which would result in very high adjustment costs. Since the tension of the wire rope 1 changes mainly due to elevator operation, this invention addresses this issue by installing a wire rope tension adaptive device at the end of the wire rope 1. The wire rope 1 passes through the limiting rods and fixing rods at both ends of the hydraulic device, keeping it taut at these three points. One fixing rod is connected to the hydraulic device 2, and the other is installed on the anti-derailment body 3. The fixing rod is vertically connected to the wire rope 1 and applies a vertical force to adjust the tension. When elevator operation causes changes in the tension of several wire ropes 1 near the elevator, the wire rope 1 will adjust its tension accordingly. The movement of a fixed rod causes the corresponding fixed rod to move, which in turn causes a change in the hydraulic pressure within the corresponding slot of the fixed rod in the hydraulic device. The overall hydraulic pressure of the hydraulic device 2 remains constant. When the movement of a fixed rod causes a change in the hydraulic pressure of the corresponding hydraulic chamber, the hydraulic pressure in the other hydraulic chambers in the hydraulic device 2 will change accordingly, causing the fixed rod connected to the corresponding hydraulic chamber to move. When the fixed rod connected to the hydraulic device 2 moves, it will cause the steel wire rope 1 fixed to the fixed rod to move, thereby adjusting the tension of the steel wire rope and achieving adaptive changes in the tension of the steel wire rope 1.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the anti-detachment main body 3 is equipped with an anti-detachment main plate 3.1. Anti-detachment connecting rods 3.2 are located on both sides of the anti-detachment main plate 3.1. Several No. 1 wire rope fixing rods 3.3 are located at the center of the same side of the anti-detachment main plate 3.1 and the anti-detachment connecting rods 3.2. Each No. 1 wire rope fixing rod 3.3 includes a rod body 3.3.1 and a No. 1 fixing rod connector 3.3.2. One end of the rod body 3.3.1 is equipped with a spring. The No. 1 fixing rod connector 3.3.2 is located at the spring-loaded end of the rod body 3.3.1 and connected to the spring. The other end of the rod body 3.3.1 is connected to one side of the anti-detachment main plate 3.1. Several holes are provided on the side of the anti-detachment main plate 3.1. Each hole is fitted with a No. 1 wire rope fixing rod 3.3, which is fixed and locked in the hole using conventional fixing methods. A spring is installed between the No. 1 fixed rod joint 3.3.2 and the rod body 3.3.1. When the tension of the wire rope 1 changes, the wire rope 1 will compress the No. 1 fixed rod joint 3.3.2. This compressive force is very large. If the No. 1 fixed rod joint 3.3.2 is subjected to a large compressive force from the wire rope 1, the spring installed between the No. 1 fixed rod joint 3.3.2 and the rod body 3.3.1 will be compressed, providing a certain buffer to the No. 1 fixed rod joint 3.3.2 and simultaneously providing a certain elastic force to reduce the compressive force on the No. 1 fixed rod joint 3.3.2. The No. 1 fixed rod joint 3.3.2 is generally U-shaped, with a notch in the center and flat surfaces on both sides of the notch. The hydraulic device 2 has several No. 2 wire rope fixing rods 2.1 on its side. Each No. 2 wire rope fixing rod 2.1 includes a No. 2 fixing rod connector 2.1.1 and a rod body. The No. 2 fixing rod connector 2.1.1 is located at one end of the rod body, and the other end of the rod body is connected to the side of the hydraulic device 2. The No. 2 fixing rod connector 2.1.1 has a notch in the middle, the size of which is slightly larger than the diameter of the wire rope 1. The notch has flat surfaces on both sides. The No. 1 fixing rod connector 3.3.2 and the No. 2 fixing rod connector 2.1.1 are matched to form a hole, the size of which is slightly larger than the diameter of the wire rope 1. The bend of the wire rope is fixed in the hole. The flat surfaces on both sides of the notch on the first fixed rod connector 3.3.2 correspond to the flat surfaces on both sides of the notch on the second fixed rod connector 2.1.1 and are joined together to form a hole for installing the wire rope 1. Since the diameters of the notches on both the first and second fixed rod connectors 3.3.2 and 2.1.1 are slightly larger than the diameter of the wire rope, the wire rope 1 still has some room to move when it is fixed in the hole formed by the notch. The fixed shape in the hole is an angled shape. When the tension of the wire rope 1 changes due to elevator operation, the force received by the wire rope is very large. This device adjusts the tension of the wire rope from the vertical direction.Therefore, if the diameter of the hole is equal to that of wire rope 1, it will first cause the wire rope to be unable to be easily installed into the hole. Simultaneously, because wire rope 1 is tightly locked in the hole, when wire rope 1 drives the fixed movement or the fixed movement in turn drives the fixed rod, both wire rope 1 and the hole of the fixed rod will be subjected to greater forces. This could even lead to the fixed rod and wire rope jamming due to excessive tightness, resulting in wire rope 1 breaking or the fixed rod being damaged. This would not only cause the elevator to stop operating and require repair, but also pose a safety hazard if such a phenomenon occurs during elevator operation. Connecting rod slots 2.2 are provided on the two surfaces connected to the side of the second wire rope fixed rod 2.1. The center of the connecting rod slot 2.2 has a hollow groove, the size of which is adapted to the size of the anti-disengagement connecting rod 3.2. The anti-detachment main body 3 is fixed to the connecting rod slot 2.2 on the hydraulic device 2 via the anti-detachment connecting rod 3.2. The anti-detachment connecting rod 3.2 can be directly fixed in the empty slot of the connecting rod slot 2.2, and at the same time, the anti-detachment connecting rod 3.2 can also undergo a certain displacement within the empty slot. The displacement amplitude is adapted to the displacement amplitude of the second wire rope fixing rod 2.1 within the hydraulic device 2. When the hydraulic device 2 adjusts the wire rope tension through internal hydraulic balance, it will drive the second wire rope fixing rod 2.1 to move perpendicular to the wire rope 1. The second wire rope fixing rod 2.1 will simultaneously drive the first wire rope fixing rod 3.3 to move. Since the first wire rope fixing rod 3.3 is locked and fixed to the side of the anti-detachment main body, the anti-detachment connecting rod 3.2 needs to first displace within the empty slot of the connecting rod slot 2.2 to ensure that the entire device can move in coordination and will not be damaged. Traditional wire rope tension adaptive devices embed the end of the wire rope into the corresponding hydraulic cavity of the hydraulic system. When the tension of the wire rope changes, the hydraulic pressure in the corresponding hydraulic cavity changes. However, the overall hydraulic pressure within the hydraulic system must remain constant, causing the other hydraulic cavities to move. This, in turn, moves the wire rope within those cavities, thus maintaining a relatively stable tension across the entire row of wire ropes. However, because of this installation method, the end of the wire rope is fixed inside the hydraulic system, making it impossible to install a spring at the end of the wire rope. When installing the wire rope tension adaptive device and the wire rope, the initial tension of the wire rope needs to be adjusted to a stable state. The conventional and practical method is to install a spring at the end of the wire rope and adjust the tension of the wire rope by adjusting the spring at different ends of the wire rope after installation. However, due to the installation method, the existing technology makes it impossible to install a spring at the end of the wire rope for initial tension adjustment. Although the wire rope tension adaptive device can adaptively adjust the tension of the wire rope, if the initial tension of the wire rope is unbalanced, it will affect the operation of the elevator. At the same time, the tension of the wire rope may become further unbalanced due to the operation of the elevator, threatening the daily operation safety of the elevator. The fixing rod of this device is installed vertically to the wire rope and adjusts the tension, so it does not affect the installation of the wire rope at the end, which is convenient for disassembly and assembly, and can also keep the wire rope in a state of tension balance after installation.

[0028] like Figure 6 As shown, the angled steel wire rope 1 at the splicing hole of the first fixed rod joint 3.3.2 and the second fixed rod joint 2.1.1 is subjected to forces in three directions: the force F1 acting on the upper end of the steel wire rope 1 towards the limit rod, the force F2 acting on the lower end of the steel wire rope 1 towards the lower limit rod, and the horizontal force Ft at the angle of the steel wire rope 1. The angle between one side of the steel wire rope 1 and the horizontal force is α. Therefore, F1 = Ft / (2*cos(a)), F2 = Ft / (2*cos(a)), and Ft = (F1 + F2)*cos(a). Based on the existing steel wire rope force formula, the magnitude of the force on the steel wire rope at different bending angles can be calculated. Changing the height of the limit rod can change the bending angle of the steel wire rope. Based on the actual force range of the steel wire rope during elevator operation, the most suitable limit rod height can be selected for manufacturing, improving the service life of the adjustment device and ensuring the daily operational safety of the steel wire rope.

[0029] In operation: The wire rope tension adaptive device of this invention mainly consists of a hydraulic device, fixed rods, an anti-derailment body 4, springs, etc. Multiple fixed rods are installed on the hydraulic device and the anti-derailment body, with their outer sides corresponding to and pressing against each wire rope. The anti-derailment body 4 is installed on the outside of the hydraulic device, and it is fixed with slots, springs, etc. The slots hold the wire rope from the outside, and the springs push the slots to tightly press the wire rope. This wire rope tension adaptive device can be installed independently, attached to the wire rope near the rope end. The wire rope passes between the slot on the anti-derailment body fixed to the outer side of the middle of the device and the fixed rods on the hydraulic device. When the tension of one wire rope increases, the thrust of the wire rope on the fixed rod of the hydraulic device also increases. Since the hydraulic pressure is equal everywhere, this increases the outward thrust of the other fixed rods, thereby maintaining the tension of the wire rope within a certain range to achieve equilibrium.
