Description

Technical Field

[0001] This utility model relates to the technical field of tension detection devices, specifically to an elevator wire rope tension detection device. Background Technology

[0002] Elevator wire ropes are the core component of elevator suspension systems. Their tension balance directly affects the safety, stability, and service life of elevator operation. Uneven tension can cause some wire ropes to be subjected to excessive force, accelerate wear, and even lead to breakage risks. Therefore, tension testing is a key part of elevator maintenance and safety inspection.

[0003] In existing technologies, the inspection of elevator wire ropes is generally carried out by manual inspection by staff. This method makes it difficult to determine whether the tension of each elevator wire rope is uniform and has very low accuracy. Another method is to use elevator wire rope tension testing devices to test the tension of the wire ropes. However, existing tension testing devices are difficult to clamp and fix wire ropes of different diameters, making it inconvenient to perform tension testing. Utility Model Content

[0004] This utility model proposes an elevator wire rope tension detection device to solve the problems in the prior art that it is difficult to clamp and fix wire ropes of different diameters, making it inconvenient to perform tension detection and resulting in low accuracy of tension detection.

[0005] The technical solution of this utility model is as follows: An elevator wire rope tension detection device includes a base, a fixed frame, an arc-shaped seat, a fixing mechanism, a mounting frame, and a detection mechanism. Two fixed frames are symmetrically arranged on the base. The arc-shaped seat is fixedly connected inside the fixed frame to support both ends of the wire rope. The fixing mechanism is arranged on the fixed frame to cooperate with the arc-shaped seat to press against and fix the wire rope. The mounting frame is fixedly connected to the base and is located at the center of the base. The detection mechanism is arranged on the mounting frame to detect the tension of the wire rope.

[0006] Preferably, the fixing mechanism includes a fixing plate and a pressing plate, one end of the fixing plate is fixedly connected to one end of the fixing frame, and the pressing plate is movably disposed within the fixing frame by a locking member.

[0007] Furthermore, the locking component includes a rotating plate, a connecting shaft, a knob, an external thread, and a screw hole. The rotating plate is rotatably disposed within the fixed plate. One end of the connecting shaft passes through one end of the pressing plate and is coaxially and fixedly connected to one end of the rotating plate. The other end of the connecting shaft passes through the fixed plate and extends outward. The knob is coaxially and fixedly connected to the other end of the connecting shaft. The external thread is fitted onto the connecting shaft and is coaxially and fixedly connected to the external thread. A screw hole is provided on the fixed plate to mate with the external thread. The external thread mates with the inner wall thread of the screw hole.

[0008] Furthermore, the detection mechanism includes a cylinder, a mounting plate, a pressure sensor, a spring, and a stop plate. The cylinder is mounted on the mounting frame, and the output end of the cylinder passes through the mounting frame and extends therefrom. One end of the mounting plate is fixedly connected to the output end of the cylinder. The pressure sensor is mounted on the other end of the mounting plate. One end of the spring is fixedly connected to the other end of the pressure sensor. Two sliding grooves are formed inside the mounting frame. Both ends of the stop plate are respectively embedded in the two sliding grooves and slide against the inner wall of the sliding grooves. The top end of the stop plate is fixedly connected to the other end of the spring.

[0009] As a further embodiment of this application, a rubber pad is provided at one end of the extrusion plate, and a rubber ring is provided on the arc-shaped seat.

[0010] As a further improvement in this application, the inner diameter of the screw hole is larger than the diameter of the connecting shaft.

[0011] Based on the aforementioned scheme, the bottom end of the abutment plate is provided with an arc-shaped recess.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, by cooperating with the fixed frame, the arc-shaped seat and the fixing mechanism, the two ends of the wire rope are placed on the two arc-shaped seats respectively, and the wire rope is kept horizontal. By rotating the knob, the extrusion plate is driven to move downward along the inner wall of the fixed frame. The extrusion plate drives the rubber pad to move downward and press against the wire rope. At this time, the knob is stopped and locked by the external thread and the thread of the screw hole. This can keep the extrusion plate stable, and then the rubber pad and the rubber ring press against the wire rope and fix it stably, which can firmly fix the two ends of the wire rope.

[0014] 2. In this utility model, through the cooperation of the mounting frame and the detection mechanism, the cylinder is activated to drive the arc-shaped concave inner wall to abut against the middle of the wire rope and continue to apply longitudinal pressure to the wire rope. The spring contracts and generates an upward elastic force on the pressure sensor. The pressure sensor receives and records the pressure value. In this way, the pressure that the middle of the wire rope can withstand can be tested to calculate the tension of the wire rope. The accuracy of the data can be ensured by taking the average value of multiple measurements. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1-4 As shown, this embodiment proposes an elevator wire rope tension detection device, including a base 1, a fixing frame 2, an arc-shaped seat 3, a fixing mechanism, a mounting frame 5, and a detection mechanism. Two fixing frames 2 are symmetrically arranged on the base 1. The fixing frames 2 are U-shaped. An arc-shaped seat 3 is fixedly connected inside the fixing frame 2 to support the two ends of the wire rope 4. The two ends of the wire rope 4 are placed on the two arc-shaped seats 3 respectively. The outer side wall of the wire rope 4 abuts against the inner side wall of the fixing frame 2, which can limit the positional displacement of the wire rope 4.

[0023] like Figure 2 and Figure 3As shown, the fixing mechanism is installed on the fixing frame 2 to cooperate with the arc-shaped seat 3 to press against and fix the wire rope 4. The fixing mechanism includes a fixing plate 6 and a pressing plate 7. One end of the fixing plate 6 is fixedly connected to one end of the fixing frame 2. The pressing plate 7 is movably installed in the fixing frame 2 by a locking component. A rubber pad 19 is provided on one end of the pressing plate 7. A rubber ring 20 is provided on the arc-shaped seat 3. The rubber ring 20 is semi-circular and fixedly connected to the outer wall of the arc-shaped seat 3, which can increase the friction with the wire rope 4. The locking component includes a rotating plate 8, a connecting shaft 9, a knob 10, an external thread 11, and a screw hole 12. The rotating plate 8 is rotatably mounted inside the fixed plate 6. One end of the connecting shaft 9 passes through one end of the extrusion plate 7 and is coaxially and fixedly connected to one end of the rotating plate 8. The rotating plate 8 is cylindrical and its cross-sectional area is larger than that of the connecting shaft 9. The other end of the connecting shaft 9 passes through the fixed plate 6 and extends outward. A knob 10 is coaxially and fixedly connected to the other end of the connecting shaft 9. An external thread 11 is fitted onto the connecting shaft 9 and is coaxially and fixedly connected to it. A screw hole 12 is provided on the fixed plate 6 to mate with the external thread 11. The external thread 11 mates with the inner wall of the screw hole 12. The inner diameter of the screw hole 12 is larger than that of the connecting shaft 9. Before turning knob 10, the extrusion plate 7 and rubber pad 19 are both above the arc-shaped seat 3 and the wire rope 4. Place both ends of the wire rope 4 on the arc-shaped seats 3 within the two fixing brackets 2, and pull the ends of the wire rope 4 to keep it horizontal. At this time, the connecting shaft 9 passes through the fixing plate 6, and the external thread 11 on the connecting shaft 9 is at the top of the screw hole 12 and engages with the inner wall thread of the screw hole 12. By turning knob 10, knob 10 drives the connecting shaft 9 to rotate, and the connecting shaft 9 drives the external thread 11 to rotate. When the external thread 11 rotates, it will move along the screw hole... The inner wall of 12 moves downward, and the connecting shaft 9 rotates, which also drives the rotating plate 8 to rotate. Since the rotating plate 8 is set inside the extrusion plate 7 and the outer wall of the extrusion plate 7 abuts against the inner wall of the fixing frame 2, the downward movement of the connecting shaft 9 will drive the extrusion plate 7 to move downward along the inner wall of the fixing frame 2. The extrusion plate 7 drives the rubber pad 19 to move downward and press against the steel wire rope 4. At this time, stop rotating the knob 10. The external thread 11 is locked with the thread of the screw hole 12, which can keep the extrusion plate 7 stable, and then the rubber pad 19 and the rubber ring 20 press against and fix the steel wire rope 4 stably.

[0024] like Figure 1 and Figure 4As shown, the mounting bracket 5 is fixedly connected to the base 1, and the mounting bracket 5 is located at the center of the base 1. The detection mechanism is set on the mounting bracket 5 and is used to detect the tension of the wire rope 4. The detection mechanism includes a cylinder 13, a mounting plate 14, a pressure sensor 15, a spring 16, and a contact plate 17. The cylinder 13 is mounted on the mounting bracket 5, and the output end of the cylinder 13 passes through the mounting bracket 5 and extends outward. One end of the mounting plate 14 is fixedly connected to the output end of the cylinder 13. The pressure sensor 15 is mounted on the other end of the mounting plate 14, and one end of the spring 16 is fixedly connected to the other end of the pressure sensor 15. It should be noted that the pressure sensor 15 can be connected to one end of the spring 16. This combination is widely used in various scenarios. Its core is that the force is transmitted through the deformation of the spring 16, and then sensed by the pressure sensor 15 and converted into an electrical signal. Furthermore, the spring 16 has a high damping coefficient, making it difficult to cause the contact plate 17 to move up and down repeatedly. It can sway and withstand greater pressure. The mounting frame 5 has two sliding grooves 18. The two ends of the abutment plate 17 are respectively embedded in the two sliding grooves 18 and slide with the inner wall of the sliding grooves 18, which can limit the position of the abutment plate 17. The top of the abutment plate 17 is fixedly connected to the other end of the spring 16. The bottom end of the abutment plate 17 has an arc-shaped recess 21. After the steel wire rope 4 is fixed, the cylinder 13 is started. The output end of the cylinder 13 drives the mounting plate 14 to move downward. The mounting plate 14 drives the pressure sensor 15 to move downward. The pressure sensor 15 drives the spring 16 to move downward. The spring 16 drives the abutment plate 17 to move downward. When the abutment plate 17 moves, the inner wall of the arc-shaped recess 21 abuts against the middle of the steel wire rope 4 and continues to apply longitudinal pressure to the steel wire rope 4. The spring 16 contracts and generates an upward elastic force on the pressure sensor 15. The pressure sensor 15 receives the pressure value and records it.

[0025] Working principle: When testing the tension of the elevator wire rope 4, the two ends of the wire rope 4 are placed on two arc-shaped seats 3 respectively. The outer wall of the wire rope 4 abuts against the inner wall of the fixed frame 2, which can limit the positional displacement of the wire rope 4 and pull the two ends of the wire rope 4 to keep the wire rope 4 in a horizontal state. By rotating the knob 10, the knob 10 drives the connecting shaft 9 to rotate, and the connecting shaft 9 drives the external thread 11 to rotate. When the external thread 11 rotates, it moves downward along the inner wall of the thread hole 12. At the same time, the rotation of the connecting shaft 9 also drives the rotating plate 8 to rotate. Since the rotating plate 8 is set inside the pressing plate 7 and the outer wall of the pressing plate 7 abuts against the inner wall of the fixed frame 2, the downward movement of the connecting shaft 9 drives the pressing plate 7 to move downward along the inner wall of the fixed frame 2. The pressing plate 7 drives the rubber pad 19 to move downward and press against the wire rope 4. At this time, the rotation stops. Knob 10 is locked in place by the threaded external thread 11 and threaded screw hole 12, which keeps the extrusion plate 7 stable. This allows the rubber pad 19 and rubber ring 20 to press and secure the wire rope 4. Then, cylinder 13 is activated. The output end of cylinder 13 drives the mounting plate 14 to move downward. The mounting plate 14 drives the pressure sensor 15 to move downward. The pressure sensor 15 drives the spring 16 to move downward. The spring 16 drives the abutment plate 17 to move downward. When the abutment plate 17 moves, the inner wall of the arc-shaped recess 21 abuts against the middle of the wire rope 4 and continues to apply longitudinal pressure to the wire rope 4. The spring 16 contracts and generates an upward elastic force on the pressure sensor 15. The pressure sensor 15 receives and records the pressure value. This allows the pressure that the middle of the wire rope 4 can withstand to be tested, and the tension of the wire rope 4 can be calculated. The accuracy of the data can be ensured by taking the average value of multiple measurements.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
