Description

Technical Field

[0001] The utility model relates to the technical field of anti-deviation of return rope wheels, in particular to an anti-deviation structure of a return rope wheel in an elevator car. Background Art

[0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. It is a fixed lifting device that serves specified floors. The output and transmission of power mainly rely on the traction machine system, which is mainly composed of a traction machine, traction wire rope, guide wheel and anti-rope wheel.

[0003] According to the description in the elevator car return rope pulley anti-deviation structure disclosed on the patent website (authorization announcement number: CN 218174314 U), "The present application relates to an elevator car return rope pulley anti-deviation structure, and relates to the field of elevator equipment, which includes a limit plate, the limit plate is fixedly connected to the upper beam, an avoidance groove is provided on one side of the limit plate, the rotating shaft is located in the avoidance groove, a gear is provided on the side of the limit plate away from the upper beam, and the rotating shaft is provided with teeth at the gear, and the teeth and the gear are meshed with each other. The present application has the effect of reducing the probability of deviation of the return rope pulley."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, an elastic pad is provided on the side of the limit plate away from the upper beam. The elastic pad can be set as a pad made of elastic material such as a rubber pad. The elastic pad simultaneously opens an arc-shaped groove on the bottom edge at the avoidance groove, and the elastic pad abuts against the rotating shaft at the bottom wall of the arc-shaped groove. In actual use, since the device is provided with a tension rod to limit the rotating shaft, the length of the tension rod is fixed, which makes it inconvenient for staff to replace and repair it later. At the same time, the return rope pulley of the device is only fixedly installed with the rotating shaft. Since the steel cable directly acts on the return rope pulley, the return rope pulley is prone to deviation. Therefore, it is necessary to improve the anti-deviation structure of the return rope pulley of the elevator car to solve the above problems. Utility Model Content

[0030] The limit anti-deviation mechanism 4 includes an anti-deviation component 41 and a limit component 42. The anti-deviation component 41 is arranged inside the installation upper beam 1, and the limit component 42 is arranged outside the installation upper beam 1.

[0031] Further, the anti-deviation component 41 includes a mounting post 411 which is fixedly connected inside the mounting upper beam 1. An outer bearing 412 is fixedly connected to the mounting post 411, and a return pulley body 413 is fixedly connected to the outer part of the bearing 412. A bolt 416 is threadedly connected inside the mounting post 411. A slider 414 is rotatably connected to the outer part of the bolt 416, and a limiting block 415 is fixedly connected to the top of the slider 414. This facilitates adjusting the position of the slider 414, thus facilitating the later maintenance and repair by the staff while preventing the bearing 412 from deflecting during use, thereby achieving anti-deviation during the rotation of the return pulley body 413.

[0032] Further, a groove is provided at the corresponding position of the mounting post 411 and the slider 414, and the slider 414 is slidably connected inside the groove. The limiting block 415 contacts the bearing 412, facilitating a more stable anti-deviation process.

[0033] Further, the limiting component 42 includes a connecting platform 421 which is fixedly connected to the outside of the mounting upper beam 1. A bidirectional threaded rod 422 is rotatably connected inside the connecting platform 421. A limiting rod 423 is fixedly connected inside the connecting platform 421. A movable plate 424 is slidably connected to the outer part of the limiting rod 423. A clamping block 425 is fixedly connected to one end of the movable plate 424 away from the connecting platform 421. This facilitates the clamping block 425 to limit the mounting post 411, preventing accidental situations such as the forward and backward displacement of the mounting post 411 during use and increasing the limiting effect.

[0034] Further, the movable plate 424 is threadedly connected to the bidirectional threaded rod 422. A groove is provided at the corresponding position of the connecting platform 421 and the movable plate 424, and the movable plate 424 is slidably connected inside the groove. A groove is provided at the corresponding position of the mounting post 411 and the clamping block 425, and the clamping block 425 contacts the mounting post 411, facilitating a more stable limiting process. Embodiment

[0035] Please refer to Figures 6-7 and, in combination with Embodiment 1, it is further obtained that the auxiliary limiting mechanism 5 includes a connecting block 51 which is fixedly connected to the outside of the mounting upper beam 1. A connecting box 52 is fixedly connected to one end of the connecting block 51 away from the mounting upper beam 1. A spring 53 is fixedly connected inside the connecting box 52. A movable block 55 is fixedly connected to one end of the spring 53 away from the connecting box 52. A clamping block 54 is fixedly connected to one end of the movable block 55 away from the spring 53. This facilitates the clamping block 54 to limit the limiting block 415, preventing the position of the limiting block 415 from changing during long-term use or due to accidental situations such as vibration.

[0036] Further, the clamping block 54 is slidably connected to the connecting box 52, the movable block 55 is slidably connected to the connecting box 52. A groove is provided at the corresponding position of the clamping block 425 and the clamping block 54, and the clamping block 54 is slidably connected inside the groove, facilitating a more stable use process.

[0037] In the actual operation process, when this device is in use, first install the steel cable on the return rope wheel body 413, and cooperate with the anti-jump frame 2 and the reinforcement plate 3 to avoid unexpected situations such as fracture during the use of the elevator. Through the provided bearing 412, the return rope wheel body 413 rotates relative to the mounting column 411 to achieve the transmission of the steel cable. The staff rotates the bolt 416. Through the rotation of the provided bolt 416, the limit and installation of the slider 414 are achieved, and in cooperation with the limit block 415, the bearing 412 is thus limited. The staff rotates the bidirectional threaded rod 422. Through the rotation of the provided bidirectional threaded rod 422 and in cooperation with the limit rod 423, the movable plate 424 moves, and thus the clamping block 425 moves. The staff pulls the clamping block 54. Through the movement of the provided clamping block 54 and in cooperation with the spring 53, the clamping block 54 moves, thereby realizing the limit of the clamping block 54 on the limit block 415.
