Description

Technical Field

[0001] The present invention relates to the technical field of elevator compensation chains, and in particular to an anti-oscillation elevator compensation chain limiting structure and a use method thereof. Background Art

[0002] The elevator compensation chain is used to be installed on the elevator for use. Since a steel wire rope is set on one side of the elevator, the weight of the steel wire rope will cause the elevator to be not stable enough during operation. In order to make the elevator run smoothly, an elevator compensation chain is installed in the elevator to compensate for the weight of the steel wire rope and make the elevator run smoothly. The structure of the elevator compensation chain is an iron chain, and the outside of the iron chain is wrapped with PVC rubber composite material. In order to ensure that the elevator compensation chain can be used smoothly, a limiting structure is required to limit it.

[0003] The defects of the existing elevator compensation chain limiting structure are:

[0004] 1. Patent document US11001476B2 discloses a compensating chain stabilization device and method. "A compensating chain stabilization device for an elevator includes a magnetic field generating device configured to generate a magnetic field to limit the jitter of the compensating chain. An elevator shaft and an elevator system according to an embodiment of the present invention include a compensating chain stabilization device according to an embodiment of the present invention. The device and method of the present invention can suppress the jitter of the compensating chain as much as possible and avoid other problems related to the jitter of the compensating chain." However, this stabilization device can only stabilize the elevator compensating chain to a certain extent, which can easily lead to low stability of the compensating chain.

[0005] 2. Patent document JP2017178546A discloses an elevator compensating chain guide device. However, when guiding the compensating chain, the guide device is prone to generate large friction, which can easily cause damage to the compensating chain.

[0006] 3. Patent document JP2007168939A discloses a compensating chain guide device for an elevator. However, the guide device lacks a noise detection function. If the compensating chain is damaged or the friction is too large, the staff cannot be informed in time.

[0007] 4. Patent document CN203699599U discloses an elevator compensation chain limit device. However, the limit device has an automatic lubrication function for the compensation chain, which may cause the compensation chain to contact the limit device, resulting in excessive noise.

[0017] Preferably, the method of using the elevator compensation chain limiting structure is as follows:

[0018] S1. First, determine the number of elevator compensating chains. Generally, an elevator has two compensating chains. Therefore, when using the elevator compensating chain limiting structure, both the first mounting bracket and the second mounting bracket must be installed. During installation, to ensure that the first mounting bracket and the second mounting bracket are on the same horizontal line, extend the docking plate in the first mounting bracket and insert it into the interior of the second mounting bracket. This ensures that the first mounting bracket and the second mounting bracket are on the same horizontal line, thereby ensuring that the two elevator compensating chains remain aligned during limiting.

[0019] S2. When the elevator compensation chain limiting structure is in use, the elevator compensation chain passes through the inside of the limiting cylinder and the bottom of the limiting shaft respectively. The limiting cylinder is located at a high position, and the limiting shaft is located at the bottom of the elevator compensation chain, so that the elevator compensation chain can be well limited to prevent the elevator compensation chain from oscillating during use;

[0020] S3. At the same time, the bottom end of the elevator compensation chain is limited by the limiting discs and limiting shafts on both sides, so that the elevator compensation chain cannot swing significantly forward and backward or left and right, thereby making the elevator compensation chain more stable. In order to avoid large friction and noise with the limiting discs and limiting shafts, protective pads and protective covers are provided to reduce the noise and damage to the elevator compensation chain during use of the elevator compensation chain limiting structure.

[0021] Preferably, the step S1 further includes the following steps:

[0022] S11. The elevator compensating chain limiting structure can also be used individually. Each elevator compensating chain limiting structure can be fixed for use by a first fixing seat and a second fixing seat at the bottom. A docking plate slidably mounted on one side of the first mounting seat can slide into the interior of the first mounting seat. The fixing plate is rotated and fixed to one side of the first mounting seat using fixing bolts, thereby fixing the docking plate to the interior of the first mounting seat.

[0023] The step S2 also includes the following steps:

[0024] S21. When limiting the elevator compensating chain, in order to prevent the elevator compensating chain from generating friction with the inside of the limiting cylinder in the limiting cylinder, a number of balls are arranged on the inner wall of the limiting cylinder. The balls can rotate, and the elevator compensating chain will contact the balls in the limiting cylinder. The balls rotate during friction, thereby reducing the internal friction between the elevator compensating chain and the limiting cylinder, so that the elevator compensating chain can be used for a longer period of time.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In order to solve the stability of the elevator compensation chain, the present invention installs the anti-vibration component at a high place through a telescopic rod. The telescopic rod can be extended and retracted upward at the top of the support arm, thereby increasing the height of the anti-vibration component. Then, the threaded fixing column is rotated into the threaded hole to fix the telescopic rod, so that the elevator compensation chain is limited by the limiting cylinder in the anti-vibration component. The elevator compensation chain passes through the limiting cylinder respectively, so that the compensation chain has two limiting points, thereby making the compensation chain more stable during use and avoiding vibration.

[0027] 2. In the present invention, since the elevator compensation chain passes through the limit cylinder, in order to avoid damage to the elevator compensation chain caused by large friction with the limit cylinder, a number of balls are arranged inside the limit cylinder for movement. When the elevator compensation chain and the inner wall of the limit cylinder produce friction contact, the balls can rotate, thereby reducing friction between them and avoiding damage to the outer protective cover of the elevator compensation chain due to friction.

[0028] 3. In the present invention, the noise detector is located inside the mounting tube. A sound receiving head is installed at the detection end of the noise detector. The sound receiving head is used to receive the noise generated by the friction between the elevator compensation chain and the limit tube. The noise detector is electrically connected to a signal transmission module. The signal transmission module is used to transmit the noise signal detected by the noise detector. The noise detector is electrically connected to an intelligent controller through the signal transmission module, and the intelligent controller is located in the elevator control room, so that the staff can discover and deal with it in time.

[0029] 4. If the noise detected by the noise detector in the present invention exceeds the maximum value set by the intelligent controller, the intelligent controller will control the actuator to send a signal, thereby controlling the operation of the actuator, and pushing the lubricating oil into the interior of the limit cylinder through the actuator, thereby ensuring the lubrication of the elevator compensation chain, making the elevator compensation chain more lubricated, and reducing the noise generated in the limit cylinder.

[0042] See also Figure 1 、 Figure 3 、 Figure 4 and Figure 7 , an embodiment provided by the present invention: an anti-oscillation elevator compensation chain limiting structure;

[0043] It includes a mounting arm 11, a support arm 17, a support tube 26 and a limiting tube 37. A support arm 17 is installed on one side of the mounting arm 11. A telescopic rod 20 is telescopically provided at the top of the support arm 17. A connecting rod 22 is provided at the top of the telescopic rod 20. A mounting block 23 is installed at one end of the connecting rod 22. The front and back sides of the mounting block 23 are symmetrically provided with a support tube 26. An anti-vibration component is provided at one end of the support tube 26. The anti-vibration component is used to limit the elevator compensation chain. The anti-vibration component includes a limiting tube 37, and the limiting tube 37 is connected to the support tube 26. A plurality of circular limiting grooves 38 are provided on the inner side of the limiting tube 37. A ball 39 is provided inside the circular limiting groove 38. The ball 39 can reduce the friction between the limiting tube 37 and the elevator compensation chain by rolling, and the ball 39 protrudes from the inner side of the circular limiting groove 38. A connecting plate is provided at the other end of the support arm 17. 18. The connecting plate 18 is fixed to one side of the mounting arm 11 by bolts. A threaded fixing column 19 is provided on the top front of the support arm 17. A plurality of threaded holes 21 are provided on the front of the telescopic rod 20, and the threaded holes 21 are threadedly connected to the threaded fixing column 19. A limit assembly is provided on the inner side of the mounting arm 11. The limit assembly is used to limit the elevator compensation chain to prevent the bottom of the elevator compensation chain from shaking significantly. The limit assembly includes a limit disc 12, and the limit disc 12 is symmetrically connected to the inner side of the mounting arm 11. A protective pad 13 is provided on the inner side of the limit disc 12, and the protective pad 13 is used to prevent the elevator compensation chain from colliding with the limit disc 12. A limit shaft 14 is provided between the limit discs 12, and a protective sleeve 16 is provided on the outer side of the limit shaft 14. Rotating shafts 15 are installed at both ends of the limit shaft 14, and the rotating shaft 15 is rotatably connected to the limit disc 12;

[0044] The mounting arm 11 is used to install the limit assembly, which limits the elevator compensation chain through the limit disc 12 and the limit shaft 14. The elevator compensation chain passes under the limit shaft 14, so that the limit shaft 14 limits the front and back swing of the elevator compensation chain. The limit disc 12 limits the left and right swing of the elevator compensation chain, so that when the elevator compensation chain is in use, it can be prevented from not being limited at the bottom and causing the elevator compensation chain to swing. At the same time, the protective cover 16 and the protective cover installed on the limit shaft 14 and the limit disc 12 The protective pad 13 can protect the elevator compensation chain. When the limit shaft 14 and the limit disc 12 limit the elevator compensation chain, a collision will occur. The use of the protective cover 16 and the protective pad 13 can reduce the noise caused by the collision, and also prevent the collision from causing damage to the leather cover on the outside of the elevator compensation chain. The limit shaft 14 is installed through the rotating shaft 15 so that the limit shaft 14 can rotate. When the elevator compensation chain and the limit shaft 14 produce friction, the friction force will cause the limit shaft 14 to rotate, thereby playing a role of friction. The ladder compensation chain is used in elevators and has a certain height. If only the bottom limit is used, the stability of the elevator compensation chain cannot be well solved. Then, the anti-vibration component is installed at a high place through the telescopic rod 20. The telescopic rod 20 can be extended and retracted upward at the top of the support arm 17, thereby increasing the height of the anti-vibration component. Then, the threaded fixing column 19 is rotated into the threaded hole 21 to fix the telescopic rod 20, so that the elevator compensation chain is limited by the limit cylinder 37 in the anti-vibration component. The elevator compensation chain passes through the limit cylinder 37 respectively, so that the compensation chain has two limit points, which makes the compensation chain more stable during use and avoids oscillation. Since the elevator compensation chain passes through the limit cylinder 37, in order to avoid large friction with the limit cylinder 37 and thus damage to the elevator compensation chain, a number of balls 39 are arranged inside the limit cylinder 37. When the elevator compensation chain is in friction contact with the inner wall of the limit cylinder 37, the balls 39 can rotate, thereby reducing friction between them and avoiding damage to the outer protective cover of the elevator compensation chain due to friction.

The noise detector 35 is electrically connected to the intelligent controller 42 through the signal transmission module 46. The intelligent controller 42 is located in the elevator control room. A data analysis module 45 is electrically installed inside the intelligent controller 42. The data analysis module 45 is used to analyze the noise signal transmitted by the signal transmission module 46 to the intelligent controller 42.

[0047] The mounting tube 34 provides an installation position for the noise detector 35 so that it can be installed. The support column 33 is used to install the mounting tube 34 above the mounting block 23. The noise detector 35 detects the friction between the elevator compensation chain and the limit tube 37 through the sound receiving head 36. The louder the detected sound, the greater the friction generated, which makes it easier for the staff to understand the friction conditions of the elevator compensation chain. The noise detected by the noise detector 35 can be transmitted to the intelligent controller 42 through the signal transmission module 46. The maximum value of the noise is set through the data setting module 44 in the intelligent controller 42. If the noise generated exceeds the set maximum value, the intelligent controller 42 will control the signal of the actuator 49 to control the operation of the actuator 49.

[0054] The method of using the elevator compensation chain limiting structure is as follows:

[0055] S1. First, determine the number of elevator compensating chains. Generally, an elevator has two compensating chains.

[0056] S2. When the elevator compensation chain limiting structure is in use, the elevator compensation chain passes through the interior of the limiting cylinder 37 and the bottom of the limiting shaft 14 respectively. The limiting cylinder 37 is located at a high position, and the limiting shaft 14 is located at the bottom of the elevator compensation chain, so that the elevator compensation chain can be well limited to prevent the elevator compensation chain from oscillating during use;

[0057] S3. At the same time, the bottom end of the elevator compensation chain is limited by the limiting disc 12 and the limiting shaft 14 on both sides, so that the elevator compensation chain cannot swing significantly forward and backward or left and right, thereby making the elevator compensation chain more stable. In order to avoid large friction and noise with the limiting disc 12 and the limiting shaft 14, a protective pad 13 and a protective cover 16 are provided to reduce the noise and damage to the elevator compensation chain during use of the elevator compensation chain limiting structure.

[0058] S1 also includes the following steps:

[0059] S11. This elevator compensating chain limiting structure can also be used individually. Each elevator compensating chain limiting structure can be fixed and used by the first fixing seat 2 and the second fixing seat 9 at the bottom. The docking plate 4 slidably mounted on one side of the first mounting seat 1 can slide into the interior of the first mounting seat 1. By rotating the fixing plate 6, the fixing plate 6 is fixed to one side of the first mounting seat 1 using the fixing bolt 7, thereby fixing the docking plate 4 inside the first mounting seat 1.

[0060] S2 also includes the following steps:

[0061] S21. When limiting the elevator compensation chain, in order to prevent the elevator compensation chain from generating friction with the inside of the limiting cylinder 37 in the limiting cylinder 37, a plurality of balls 39 are provided on the inner wall of the limiting cylinder 37. The balls 39 can rotate, and the elevator compensation chain will contact the balls 39 in the limiting cylinder 37. The balls 39 rotate during friction, thereby reducing the internal friction between the elevator compensation chain and the limiting cylinder 37, so that the elevator compensation chain can be used for a longer period of time.

[0062] Working principle: Before using the elevator compensation chain limiting structure, you should first check whether the elevator compensation chain limiting structure has any problems that affect its use. First, install the elevator compensation chain limiting structure through the first mounting seat 1 and the second mounting seat 8 at the position where it needs to be used, and pass the elevator compensation chain through the inside of the limiting cylinder 37 and the bottom of the limiting shaft 14 respectively. Then use the telescopic rod 20 to extend upward to increase the height of the limiting cylinder 37, so that the limiting cylinder 37 can limit the elevator compensation chain at a high place. When the elevator compensation chain is in use, the noise detector 35 will detect the noise generated by friction. If the external protective cover of the elevator compensation chain is damaged or lacks lubricating oil, the detected noise is too loud and the intelligent controller 42 will display it, so that the staff can deal with it in time.
