[0024] The preferred embodiments of the utility model are explained in detail below in conjunction with the drawings, so that the advantages and characteristics of the utility model can be more easily understood by the person skilled in the art, and the protection scope of the utility model is more clearly and explicitly defined.
[0025] As the accompanying Figures 1-4The anti-shaking device 5 for the speed limiter wire rope 2 of the elevator is shown in the embodiment. The elevator in the embodiment is a conventional device in the prior art, and the specific components and operation principles are in the prior art. The elevator includes a car 11 guide rail 1, a car 11, a safety gear lifting device 7, a speed limiter 3, a speed limiter wire rope 2, a tensioning device 31, and the like. The speed limiter 3 is installed at the top of the shaft, and the tensioning device 31 is installed at the bottom of the shaft. The speed limiter wire rope 2 is wound between the guide wheels of the speed limiter 3 and the guide wheels of the tensioning device 31. The speed limiter wire rope 2 is arranged on one side of the car 11 guide rail 1 in the width direction. In the above installation manner, the speed limiter wire rope 2 has a first straight section 21 close to the car 11 guide rail 1 and a second straight section 22 away from the car 11 guide rail 1. The first straight section 21 is the speed limiter wire rope 2 on the safety gear lifting side, and the second straight section 22 is the speed limiter wire rope 2 on the non-safety gear lifting side. The safety gear lifting device 7 is connected to the first straight section 21.
[0026] The anti-shaking device 5 of the embodiment is arranged on the upper and lower sides of the speed limiter wire rope 2. The anti-shaking device 5 includes a fixed support 51, a connecting support 52, and a U-shaped piece 53. The fixed support 51 is formed by bending a metal plate. The guide rail pressing plate and fasteners are used to fix the fixed support 51 on the car 11 guide rail 1. The connecting support 52 is formed by bending a metal plate. The connecting support 52 is installed on the fixed support 51 and extends in the width direction of the car 11 guide rail 1 to span between the first straight section 21 and the second straight section 22. Specifically, a first waist-shaped hole 511 extending in the horizontal direction is processed on the fixed support 51. A second waist-shaped hole 521 extending in the horizontal direction is processed on the connecting support 52. The length direction of the first waist-shaped hole 511 and the length direction of the second waist-shaped hole 521 are perpendicular to each other in the horizontal plane. A bolt assembly 58 is inserted into the first waist-shaped hole 511 and the second waist-shaped hole 521. The bolt assembly 58 is locked to achieve the mutual locking and fixing of the fixed support 51 and the connecting support 52. The length direction of the first waist-shaped hole 511 or the second waist-shaped hole 521 is the width direction of the car 11 guide rail 1. Through the above structural design, the position of the connecting support 52 on the fixed support 51 can be adjusted, and the distance of the connecting support 52 relative to the speed limiter wire rope 2 can be adjusted. A first buffer pad 56 facing the first straight section 21 is installed on the connecting support 52. In operation, the first straight section 21 of the speed limiter wire rope 2 can contact the first buffer pad 56 when shaking to reduce the collision noise.
[0027] The two free ends of the aforementioned U-shaped piece 53 are connected with the connecting bracket 52, and a limiting space is formed between the U-shaped piece 53 and the connecting bracket 52. The second straight section 22 of the governor rope 2 is inserted into the limiting space, so as to limit the swing of the first straight section 21. The U-shaped piece 53 is sleeved with a buffer sleeve 54. The second buffer pad 57 is installed on the side of the connecting bracket 52 facing the limiting space. In operation, the second straight section 22 of the governor rope 2 can contact the second buffer pad 57 and the buffer sleeve 54 when swinging, so as to reduce the impact noise.
[0028] The first buffer pad 56, the buffer sleeve 54 and the second buffer pad 57 are all rubber pads.
[0029] Specifically, threaded sections are processed on the two free ends of the aforementioned U-shaped piece 53. At least two nuts 55 are installed on the threaded sections. The two free ends of the U-shaped piece 53 are inserted into the side plates of the connecting bracket 52, and the nuts 55 are arranged on both sides of the side plates and locked, so as to lock the U-shaped piece 53 on the connecting bracket 52.
[0030] The elevator in the embodiment further comprises a switch baffle bracket 6 installed on the car 11. The switch baffle bracket 6 is a conventional component in the prior art, and a switch baffle is installed thereon. The switch baffle is a conventional component in the elevator, which functions to limit the movement of the elevator to the limit positions of the upper terminal station and the lower terminal station, and to slow down the elevator before reaching the upper terminal station and the lower terminal station. The switch baffle bracket 6 and the connecting bracket 52 are arranged on opposite sides of the first straight section 21. The switch baffle bracket 6 is provided with a third buffer pad 61 facing the first straight section 21. Through the above structure design, the first straight section 21 of the governor rope 2 is limited between the first buffer pad 56 and the third buffer pad 61. When the first straight section 21 swings, it contacts the first buffer pad 56 and the third buffer pad 61, so as to reduce the impact noise.
[0031] In specific use, the second straight section 22 of the governor rope 2 is inserted and constrained in the limiting space, so as to limit the second straight section 22 of the governor rope 2 from swinging greatly in operation, and to contact the buffer sleeve 54 and the second buffer pad 57 to reduce the impact noise. The first straight section 21 of the governor rope 2 is limited between the first buffer pad 56 and the third buffer pad 61, so as to limit the first straight section 21 of the governor rope 2 from swinging greatly in operation, and to reduce the impact noise. The combination of the above-mentioned modes can limit the swing of the governor rope 2 (the second straight section 22) on the non-safety clamp lifting side and reduce the impact noise, and can limit the swing of the governor rope 2 (the first straight section 21) on the safety clamp lifting side and reduce the impact noise, effectively meeting the anti-swinging requirement of the governor rope 2, and having strong practicability.
[0032] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
