Description

Technical Field

[0001] This invention relates to a rope clamping mechanism for elevator traction ropes, and more particularly to a rope clamping mechanism for elevator traction ropes, belonging to the technical field of elevator rope clamping equipment. Background Technology

[0002] For traditional elevators, speed governors must be used to monitor and control the downward speed of the car at any time. However, as elevators are used, people have found that the danger of the car speeding upward and overshooting the top does exist. The reason is that when the car is empty or has a very small load, the weight of the counterweight side is greater than that of the car. Once the brake fails or the shaft, key, pin, etc. of the traction machine break, or the traction rope slips in the traction sheave due to severe wear, the upward speed of the car will occur.

[0003] The solution to this problem is to add a clamping device to the elevator's traction rope. This clamps the traction rope when it moves rapidly, fixing its movement and preventing damage from overspeeding. However, most clamping devices on the market currently only clamp the traction rope in one direction. If the traction rope still slips, the device cannot clamp and fix it, and the elevator will continue to rise and reach the top.

[0004] Therefore, there is an urgent need to improve the rope clamping mechanism used for elevator traction ropes in order to solve the above-mentioned problems. Summary of the Invention

[0005] To achieve the above objectives, the main technical solution adopted by the present invention includes: a housing, and traction rods slidably disposed on both sides of the housing. The number of traction rods is four, and each pair of traction rods forms a group. An outer clamping plate is fixedly connected to the inner side of one end of each traction rod through a fixing plate. An inner clamping plate is slidably connected to the end of the housing near the outer clamping plate. The outer clamping plate and the inner clamping plate are used for the sliding placement of the traction rope. A limiter is slidably connected to each traction rod. One end of the limiter is fixedly connected to the housing. A clamp for limiting the sliding movement of the traction rod is slidably connected inside the limiter. The traction rod is connected to a fixed connecting seat through a connecting plate. A strong spring is provided between the connecting plate and the fixed connecting seat.

[0006] The tightening mechanism includes a hydraulic telescopic rod and a connecting base for the inner clamping plate to be pushed out. The hydraulic telescopic rod is connected to a reservoir via an oil pipe. There are two hydraulic telescopic rods, each of which is rotatably connected to a rotating rod via a rotating block. The rotating rod is fixedly connected to the connecting base. One end of the connecting base is connected to the inner clamping plate via a reinforcing rod.

[0007] A reversing mechanism includes an ejector shaft and a drive motor for driving the ejector shaft. A rotating groove is provided in the middle of the outer clamping plate. The ejector shafts are all rotatably disposed inside the rotating groove. The ejector shafts are all fixedly connected to the output end of the drive motor.

[0008] Preferably, an electric telescopic rod is fixedly provided at both the upper and lower ends of the limiter, and a sliding groove is provided in the middle of the limiter for sliding connection with the traction rod. One end of the electric telescopic rod extends into the sliding groove, and the clamp is fixedly connected to one end of the electric telescopic rod.

[0009] Preferably, a rotating rod is rotatably connected to one end of the connecting plate near the strong spring. The rotating rod is located inside the strong spring and is used for stretching and extending the strong spring.

[0010] Preferably, the end of the rotating rod away from the connecting plate is provided with an external thread, and the rotating rod is threadedly connected to the fixed connecting seat through the external thread. The end of the rotating rod near the fixed connecting seat is provided with a plurality of locking grooves.

[0011] Preferably, a first return spring is fixedly installed on the outside of the hydraulic telescopic rod. The first return spring is used for the elastic return of the hydraulic telescopic rod. The hydraulic telescopic rod is connected to the inside of the liquid storage tank through the oil drain pipe and the oil supply pipe.

[0012] Preferably, a rotating connecting column is rotatably provided on one side of the connecting base, and a push plate is fixedly connected to the rotating connecting column on the side away from the connecting base. A reinforcing rod is fixedly provided at the end of the push plate away from the rotating connecting column, and the other end of the reinforcing rod is fixedly connected to the inner clamping plate. Both ends of the rotating connecting column are fixedly provided with reinforcing panels, and both reinforcing panels are fixedly connected to the push plate.

[0013] Preferably, the inner clamping plate has a plurality of limiting slots on the side near the outer clamping plate, and the limiting slots are all corresponding to the position of the rotating slot. At least four guide posts are fixedly provided on the inner clamping plate near the end of the housing, and the guide posts are respectively located at the four corners of the inner clamping plate. The inner clamping plate is slidably connected to the housing through the guide posts.

[0014] Preferably, a connecting rod is fixedly provided on the upper end of the connecting base, and a horizontal connecting rod is fixedly provided on the upper half of the connecting rod. Both ends of the horizontal connecting rod are rotatably connected to a reset chamber, and the end of the reset chamber away from the horizontal connecting rod is fixedly connected to the inner wall of the housing.

[0015] Preferably, a reset rod is rotatably disposed inside the reset chamber, and a second reset rod is fixedly disposed outside the reset rod. One end of the second reset rod is fixedly connected to the inner wall of the reset chamber, and the cross link extends into the interior of the reset chamber and is fixedly connected to the reset rod.

The guide grooves are used for sliding guidance of the traction rods.

[0017] The present invention has at least the following beneficial effects:

[0018] By setting a rotating block at the upper end of the hydraulic telescopic rod, the rotating block can be rotatably connected to the connecting base via a rotating rod. When the hydraulic telescopic rod is extended and retracted under the action of hydraulic oil, the connecting base and its upper part are tilted towards the inner clamping plate. When the hydraulic telescopic rod extends, the connecting base can be pushed towards the inner clamping plate by the rotational force. At the same time, the setting of the reinforcing rod can provide a medium between the two, so that the connecting base can push the inner clamping plate through the reinforcing rod, and the inner clamping plate can move towards the outer clamping plate, thereby increasing the clamping force on the traction rope.

[0019] By rotating an ejector shaft inside the outer clamping plate, and having the ejector shaft driven by a drive motor, the ejector shaft can contact the traction rope through the rotating groove in the middle of the outer clamping plate when the outer clamping plate moves closer to the inner clamping plate. When the distance between the inner and outer clamping plates decreases, the ejector shaft can eject the traction rope. At the same time, the drive motor can drive the ejector shaft to rotate, thereby providing a reaction force to the traction rope and significantly improving the clamping effect of the traction rope.

[0030] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] like Figures 1-8As shown, the rope clamping mechanism for elevator traction ropes provided in this embodiment includes a housing 1 and traction rods 4 slidably disposed on both sides of the housing 1. There are four traction rods 4, with each pair forming a group. An outer clamping plate 10 is fixedly connected to the inner side of one end of each traction rod 4 via a fixing plate. An inner clamping plate 9 is slidably connected to the end of the housing 1 near the outer clamping plate 10. The outer clamping plate 10 and the inner clamping plate 9 are used for the sliding placement of the traction rope. A limiter 5 is slidably connected to each traction rod 4. One end of the limiter 5 is fixedly connected to the housing 1. A clamp 28 for limiting the sliding movement of the traction rod 4 is slidably connected inside the limiter 5. A fixed connecting seat 8 is connected to the traction rod 4 via a connecting plate 7. A strong spring 6 is provided between the connecting plate 7 and the fixed connecting seat 8. Through traction... A connecting plate 7 is provided on the rod 4, and the connecting plate 7 can be connected to the fixed connecting seat 8 through the strong spring 6. At the same time, the strong spring 6 can be manually contracted, so that the strong spring 6 is in a compressed state. The limiter 5 provided on the traction rod 4 can limit the position of the traction rod 4 through the clamp 28 provided inside, so as to prevent the traction rod 4 from moving the outer clamp 10 due to the force of the strong spring 6 under normal conditions. When the clamp 28 is retracted due to external factors, the limit on the traction rod 4 is canceled, so that the traction rod 4 can move rapidly under the force of the strong spring 6, so that the outer clamp 10 can move to the position of the inner clamp 9, thereby clamping the traction rope located between the inner clamp 9 and the outer clamp 10.

[0032] The re-tightening mechanism includes a hydraulic telescopic rod 13 and a connecting base 18 for the inner clamping plate 9 to be pushed out. The hydraulic telescopic rod 13 is connected to a reservoir 2 via an oil pipe 36. There are two hydraulic telescopic rods 13, each rotatably connected to a rotating rod 15 via a rotating block 14. The rotating rod 15 is fixedly connected to the connecting base 18. One end of the connecting base 18 is connected to the inner clamping plate 9 via a reinforcing rod 33. By setting a rotating block 14 at the upper end of the hydraulic telescopic rod 13, the rotating block 14 can be rotatably connected to the connecting base 18 via the rotating rod 15. When the hydraulic... The telescopic rod 13 can extend and retract under the action of hydraulic oil, and the connecting base 18 and its upper end are all tilted towards the inner clamping plate 9. When the hydraulic telescopic rod 13 extends, the connecting base 18 can be pushed towards the inner clamping plate 9 by the action of rotational force. At the same time, the reinforcing rod 33 can provide a medium between the two, so that the connecting base 18 can push the inner clamping plate 9 through the reinforcing rod 33, so that the inner clamping plate 9 can move towards the outer clamping plate 10, thereby increasing the clamping force on the traction rope.

[0033] The reversing mechanism includes an ejector shaft 20 and a drive motor 21 for driving the ejector shaft 20. A rotating groove 19 is provided in the middle of the outer clamping plate 10. The ejector shafts 20 are all rotatably disposed inside the rotating groove 19. The ejector shafts 20 are all fixedly connected to the output end of the drive motor 21. By rotatably disposing the ejector shafts 20 inside the outer clamping plate 10 and driving the ejector shafts 20 to rotate, the ejector shafts 20 can contact the traction rope through the rotating groove 19 in the middle of the outer clamping plate 10 when the outer clamping plate 10 moves closer to the inner clamping plate 9. When the distance between the inner clamping plate 9 and the outer clamping plate 10 decreases, the ejector shafts 20 can eject the traction rope. At the same time, the drive motor 21 can drive the ejector shafts 20 to rotate, thereby providing a reaction force for the traction rope and significantly improving the clamping effect of the traction rope.

[0034] In this embodiment, as Figure 1 , Figure 5 As shown, electric telescopic rods 27 are fixedly installed at the upper and lower ends of the limiter 5. A sliding groove 29 for sliding connection with the traction rod 4 is opened in the middle of the limiter 5. One end of the electric telescopic rod 27 extends into the sliding groove 29. The clamp 28 is fixedly connected to one end of the electric telescopic rod 27. By opening the sliding groove 29 in the middle of the limiter 5, the limiter 5 can be slidably connected to the traction rod 4 through the sliding groove 29. The electric telescopic rods 27 installed at the upper and lower ends of the limiter 5 can drive the clamp 28 to move after receiving a signal, so that the clamp 28 can limit or not limit the traction rod 4.

[0035] In this embodiment, as Figure 1 , Figure 4 As shown, a rotating rod 23 is rotatably connected to the end of the connecting plate 7 near the strong spring 6. The rotating rod 23 is located inside the strong spring 6 and is used to stretch and extend the strong spring 6. The end of the rotating rod 23 away from the connecting plate 7 is provided with an external thread 24. The rotating rod 23 is threadedly connected to the fixed connecting seat 8 through the external thread 24. Several clamping grooves 26 are provided at the end of the rotating rod 23 near the fixed connecting seat 8. By rotating the rotating rod 23 at one end of the connecting plate 7, the operator can rotate the rotating rod 23 through the clamping grooves 26, so that the rotating rod 23 can drive the strong spring 6 to stretch and extend through the threaded engagement. When the traction rod 4 is not limited by the limiter 5, the strong spring 6 can contract through its own elasticity, thereby driving the traction rod 4 fixedly connected to the connecting plate 7 to move, so that the outer clamping plate 10 can quickly move towards the inner clamping plate 9 to clamp the traction rope.

[0036] In this embodiment, as Figure 1 , Figure 8As shown, a first return spring 12 is fixedly installed on the outside of the hydraulic telescopic rod 13. The first return spring 12 is used for the elastic return of the hydraulic telescopic rod 13. The hydraulic telescopic rod 13 is connected to the inside of the reservoir 2 through the oil drain pipe 37 and the oil supply pipe 36. By installing the first return spring 12 on the outside of the hydraulic telescopic rod 13, the first return spring 12 can drive the hydraulic telescopic rod 13 to retract when it is not under the action of hydraulic oil, so that the hydraulic telescopic rod 13 can return to its original state. When the hydraulic telescopic rod 13 returns to its original state, it can pull the connecting base 18 to return to its original state as well, so that the inner clamping plate 9 moves away from the outer clamping plate 10. At the same time, the hydraulic telescopic rod 13 can be connected to the inside of the reservoir 2 through the oil supply pipe 36 and the oil drain pipe 37, so that the reservoir 2 can deliver and extract hydraulic oil to the inside of the hydraulic telescopic rod 13 through the oil pump installed inside, thereby controlling the extension and retraction of the hydraulic telescopic rod 13.

[0037] In this embodiment, as Figure 1 , Figure 6 As shown, a rotating connecting column 30 is rotatably provided on one side of the connecting base 18. A push plate 32 is fixedly connected to the side of the rotating connecting column 30 away from the connecting base 18. A reinforcing rod 33 is fixedly provided at the end of the push plate 32 away from the rotating connecting column 30. The other end of the reinforcing rod 33 is fixedly connected to the inner clamping plate 9. Both ends of the rotating connecting column 30 are fixedly provided with a reinforcing panel 31, which is fixedly connected to the push plate 32. By rotatably providing the rotating connecting column 30 on one side of the connecting base 18, the push plate 32 connected to the connecting base 18 can be kept vertical and horizontal by the rotational force when the connecting base 18 is pushed out, thus preventing the push plate 32 from tilting. At the same time, the setting of the reinforcing panel 31 can increase the connection area between the push plate 32 and the rotating connecting column 30, thus preventing the force of the push plate 32 from deforming due to excessive force.

[0038] In this embodiment, as Figures 1-3 As shown, the inner clamping plate 9 has several limiting slots 22 on the side near the outer clamping plate 10. The limiting slots 22 are all corresponding to the positions of the rotating slots 19. At least four guide posts 11 are fixedly provided on the end of the inner clamping plate 9 near the shell 1. The guide posts 11 are located at the four corners of the inner clamping plate 9. The inner clamping plate 9 is slidably connected to the shell 1 through the guide posts 11. By opening the limiting slots 22 on one side of the inner clamping plate 9, the limiting slots 22 can limit and retract the top part when the ejector shaft 20 ejects the traction rope, so as to avoid direct contact with one side of the inner clamping plate 9, thereby affecting the clamping state. At the same time, the inner clamping plate 9 is slidably connected to the shell 1 through the guide posts 11, so that the guide posts 11 can provide guidance for the sliding of the inner clamping plate 9.

[0039] In this embodiment, as Figure 1 , Figure 7As shown, a connecting rod 3 is fixedly installed on the upper end of the connecting base 18. A horizontal connecting rod 17 is fixedly installed on the upper half of the connecting rod 3. Both ends of the horizontal connecting rod 17 are rotatably connected to a reset chamber 16. The end of the reset chamber 16 away from the horizontal connecting rod 17 is fixedly connected to the inner wall of the housing 1. A reset rod 34 is rotatably installed inside the reset chamber 16. A second reset spring 35 is fixedly installed on the outside of the reset rod 34. One end of the second reset spring 35 is fixedly connected to the inner wall of the reset chamber 16. The horizontal connecting rod 17 extends into the interior of the reset chamber 16 and is fixedly connected to the reset rod 34. By installing the connecting rod 3 at the upper end of the connecting base 18, it is possible to... The connecting rod 3 is rotatably connected to the reset chamber 16 via the cross link 17. At the same time, the reset rod 34 set inside the reset chamber 16 can be driven to rotate by the cross link 17. The second reset spring 35 set on the surface of the reset rod 34 can provide the reset rotation force for the reset rod 34. When the hydraulic telescopic rod 13 does not act on the connecting base 18, the second reset spring 35 can drive the reset rod 34 to rotate in a reset position through its own elasticity, thereby causing the cross link 17 fixedly connected to the reset rod 34 to rotate and reset, avoiding manual adjustment and reducing the labor intensity of manual labor.

[0040] In this embodiment, as Figures 1-2 As shown, a signal transceiver 39 is fixedly installed on the lower half of one side of the housing 1. The signal transceiver 39 is used for receiving and sending signals. Guide grooves 38 are provided on both sides of the housing 1. The traction rods 4 are slidably connected to the guide grooves 38 through pulleys. The guide grooves 38 are used for sliding guidance of the traction rods 4. By setting the signal transceiver 39 in the lower half of the housing 1, the signal transceiver 39 can send a working signal to the electrical equipment of the device after receiving an emergency stop signal, so that the device can operate normally. At the same time, the guide grooves 38 on both sides of the housing 1 can make the traction rods 4 slidably connected to the guide grooves 38 through pulleys. When the traction rods 4 are pulled, the guide grooves 38 can provide guidance for the movement of the traction rods 4 and prevent the traction rods 4 from tilting when moving.

[0041] like Figures 1-8As shown, the principle of the rope clamping mechanism for elevator traction ropes provided in this embodiment is as follows: A connecting plate 7 is provided on the traction rod 4, and the connecting plate 7 can be connected to the fixed connecting seat 8 through a strong spring 6. At the same time, the strong spring 6 can be manually contracted, so that the strong spring 6 is in a compressed state. The limiter 5 provided on the traction rod 4 can limit the position of the traction rod 4 through the clamp 28 provided inside it, so as to prevent the traction rod 4 from driving the outer clamping plate 10 under normal conditions due to the force of the strong spring 6. The displacement occurs when the clamp 28 releases its limit on the traction rod 4 due to external factors during retraction, allowing the traction rod 4 to move rapidly under the force of the strong spring 6. This causes the outer clamping plate 10 to move towards the position of the inner clamping plate 9, thereby clamping the traction rope located between the inner clamping plate 9 and the outer clamping plate 10. Simultaneously, a rotating block 14 is installed at the upper end of the hydraulic telescopic rod 13, allowing the rotating block 14 to be rotatably connected to the connecting base 18 via the rotating rod 15. When the hydraulic telescopic rod 13 is subjected to hydraulic fluid, it can move... The hydraulic telescopic rod 13 extends and extends, with the connecting base 18 and its upper part tilted towards the inner clamping plate 9. This allows the connecting base 18 to push towards the inner clamping plate 9 through rotational force. Simultaneously, the reinforcing rod 33 provides a medium between the two, enabling the connecting base 18 to push against the inner clamping plate 9 via the reinforcing rod 33. This causes the inner clamping plate 9 to move towards the outer clamping plate 10, increasing the clamping force on the traction rope. Furthermore, the force is applied within the outer clamping plate 10. The ejector shaft 20 is rotated and driven by the drive motor 21. This allows the ejector shaft 20 to contact the traction rope through the rotating groove 19 in the middle of the outer clamping plate 10 when the outer clamping plate 10 moves closer to the inner clamping plate 9. When the distance between the inner clamping plate 9 and the outer clamping plate 10 decreases, the ejector shaft 20 can eject the traction rope. At the same time, the drive motor 21 can drive the ejector shaft 20 to rotate, thereby providing a reaction force for the traction rope and significantly improving the clamping effect of the traction rope.
