Technical Field

[0001] The utility model relates to the technical field of elevator accessories, in particular to an elevator balance compensation chain guide device with an adjustment structure. Background Art

[0002] In elevators, compensation chains are needed to compensate for the weight of the wire rope to make the elevator run smoothly. As the elevator continues to move up and down, dynamic imbalance will occur, so compensation chains are used. During the operation of the elevator, the compensation chain will also move. In order to guide the compensation, a compensation chain guide device needs to be set up.

[0003] The patent specification with announcement number CN217627039U discloses a guide control device of an elevator balance compensation chain, including a bottom surface of a base plate set as an inclined bottom surface, a slide groove is opened on the bottom surface of the base plate, a slide frame that can slide back and forth along the slide groove is mounted in the slide groove, the slide frame includes a slide rod and a pulley at both ends of the bearing connected thereto, a sliding sleeve that can slide back and forth along the slide rod is arranged outside the slide rod, a limit block arranged close to the pulley is also arranged outside the slide rod, a spring located between the limit block and the sliding sleeve is also arranged outside the slide rod, the sliding sleeve is connected to a slider located directly below the sliding sleeve through a connecting rod, a compensation chain is connected to the bottom of the slider, a first buffer block and a second buffer block are respectively arranged on the bottom surface of the base plate, and a second buffer member is arranged on the side walls of the first buffer block and the second buffer block facing the slider; the utility model can realize the sliding of the compensation device along the guiding direction, avoid the problem of elevator operation shaking caused by the imbalance of gravity center of the compensation device, and realize the stable operation of the elevator lifting.

[0004] However, in the implementation of relevant technologies, it was found that the guide control device of the elevator balance compensation chain of the above-mentioned design has the following problems: in the prior art, the stability of the elevator lifting process is improved by the cooperation of components such as sliders, but in the actual use process, the slider drives the compensation chain back to the initial position through the cooperation of the buffer part. Since there is a difference in force between them, and the sliding of the slider causes deviation when the position is reset, accurate adjustment is required to ensure the correct position. In view of this, an elevator balance compensation chain guide device with an adjustment structure is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an elevator balance compensation chain guide device with an adjustment structure.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an elevator balance compensation chain guide device with an adjustment structure, comprising a bottom plate, a slider is slidably connected to one side of the bottom end of the bottom plate, and a compensation chain is passed through the bottom end of the slider, fixed plates are fixed at both ends of the bottom of the bottom plate, and an adjustment mechanism is arranged on one side of the fixed plate;

[0007] The adjusting mechanism includes a motor, which is embedded in one side of the outer wall of the fixed plate, and a bidirectional threaded rod is connected to the power output end of the motor, and a pushing plate is slidably connected to both sides of the outer wall of the bidirectional threaded rod, and a damping spring is embedded in one side of the outer wall of the pushing plate, and a clamping plate is fixed to one end of the damping spring. The pushing plate elastically pushes the clamping plate through the damping spring, and when the slider slides, it has a certain shock absorption effect to avoid damage caused by excessive impact.

[0008] As a further description of the above technical solution: the bidirectional threaded rod is threadedly connected to the pushing plate, and a sliding structure is formed between the bidirectional threaded rod and the clamping plate. The bidirectional threaded rod is driven by a motor to rotate, so that the pushing plate pushes the clamping plate to move, and the slider is reset to maintain the position accuracy.

[0009] As a further description of the above technical solution: an anti-collision pad is fixed to the outer wall of the clamping plate, and a support rod is fixed to the outer wall of the fixed plate facing the pushing plate. The support rod is used to increase the supporting force of the pushing plate to prevent the slider from being excessively impacted and deflected. At the same time, the anti-collision pad improves the anti-collision effect to avoid noise caused by excessive collisions.

[0010] As a further description of the above technical solution: a through hole is opened on the inner wall of the slider, and a supporting rod is passed through the inside of the through hole, so that the stability of the slider, the push plate and the clamping plate during the sliding process is improved by the supporting rod.

[0011] As a further description of the above technical solution: a limiting mechanism is arranged on one side of the base plate, and the limiting mechanism includes a micro push rod, which is embedded in the inside of the base plate, and a penetration rod is connected to the power output end of the micro push rod, and a limiting hole is provided at the top of the slider corresponding to the position of the penetration rod. When the slider is reset, the micro push rod works to allow the penetration rod to penetrate into the limiting hole, thereby achieving a limiting and fixing effect to prevent the slider from being offset when the guide device is not in use.

[0012] As a further description of the above technical solution: the limiting mechanism also includes an electromagnet, which is fixed to the bottom end of the penetration rod, and a permanent magnet is embedded in the interior of the limiting hole. When the micro push rod is working, the electromagnet starts magnetic attraction to the permanent magnet to further improve stability.

[0013] As a further description of the above technical solution: the size of the limiting hole matches the size of the electromagnet, and the electromagnet is magnetically connected to the permanent magnet. The size of the electromagnet is consistent with the limiting hole, which is convenient for penetration and attraction with the permanent magnet.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs an elevator balancing compensation chain guide device with an adjustment structure. A motor drives a bidirectional threaded rod, and a push plate pushes a clamping plate via a damping spring, so that the two clamping plates limit and clamp the slider, thereby ensuring the accuracy of resetting to avoid deviation and maintain accurate adjustment. When the slider slides driven by the compensation chain, the push plate is in place, and the damping spring allows the slider to have shock absorption when it hits the clamping plate. At the same time, the anti-collision pad avoids excessive collision to cause damage and excessive noise.

[0016] The utility model designs an elevator balancing compensation chain guide device with an adjustment structure. Under the support of the supporting rod, the slider, the push plate and the clamping plate remain stable when moving to avoid shaking or offsetting, and the bearing force is improved at the same time. When the slider is reset, the micro push rod works to allow the insertion rod to enter the limit hole, and cooperates with the electromagnet to magnetically absorb the permanent magnet to improve the stability of the slider during positioning, thereby maintaining the stability of the compensation chain.

[0024] As a further implementation scheme of the above technical scheme: the bidirectional threaded rod 502 is threadedly connected with the push plate 503, and a sliding structure is formed between the bidirectional threaded rod 502 and the clamping plate 505. The bidirectional threaded rod 502 is driven by the motor 501 to rotate, so that the push plate 503 pushes the clamping plate 505 to move, and the slider 2 is reset to maintain the position accuracy.

[0025] As a further implementation scheme of the above technical scheme: an anti-collision pad 6 is fixed to the outer wall of the clamping plate 505, and a support rod 7 is fixed to the outer wall of the fixed plate 4 facing the pushing plate 503. The support rod 7 is used to increase the supporting force of the pushing plate 503 to prevent the slider 2 from being excessively impacted and deflected. At the same time, the anti-collision pad 6 improves the anti-collision effect to avoid noise caused by excessive collisions.

[0026] During specific implementation, when the slider 2 drives the compensation chain 3 to be reset, the motor 501 drives the bidirectional threaded rod 502, so that the pushing plate 503 pushes the clamping plate 505 to slide along the bidirectional threaded rod 502 through the damping spring 504, so that the two clamping plates 505 can position and clamp the slider 2 to maintain the accuracy of the position.

[0027] As a further implementation scheme of the above technical scheme: a through hole 9 is opened on the inner wall of the slider 2, and a supporting rod 8 passes through the inside of the through hole 9, so as to improve the stability of the slider 2, the push plate 503 and the clamping plate 505 during the sliding process.

[0031] In specific implementation, the support rod 8 is used to keep the slider 2, the push plate 503 and the clamping plate 505 stable when sliding. When the slider 2 is clamped and positioned, the micro push rod 1001 pushes the insertion rod 1002 into the limit hole 1003 for preliminary positioning. At the same time, the electromagnet 1004 and the permanent magnet 1005 are magnetically attracted to further improve the stability of the connection.
