Description

Technical Field

[0001] This utility model relates to the technical field of elevator compensation chains, and in particular to an elevator compensation chain mounting bracket structure. Background Technology

[0002] When an elevator is running, the elevator car is connected to the counterweight on the opposite side via steel cables. When the car is on the top floor, the steel cables are on the counterweight side, adding weight to the counterweight side; when the car is on the bottom floor, the steel cables are on the car side, adding weight to the car side. As the elevator moves up and down, the steel cables will generate a dynamic imbalance, so a compensating chain is needed to compensate for the weight of the steel cables, balance this difference in height, and ensure smooth elevator operation.

[0003] A search revealed Chinese Patent Publication No. CN210103236U, which discloses a telescopic compensation chain fixing bracket, including a U-shaped frame, a fixing component, and a connecting component. The U-shaped frame and the fixing component are both fixedly installed on the outer frame of a load-bearing frame or a car frame. A stop component is hinged inside the U-shaped frame, and the stop component rotates within the hanging area inside the U-shaped frame via an elastic component. A connecting hole is provided on one end face of the U-shaped frame near the fixing component, and the connecting hole can be detachably connected to a limiting flower-shaped block at the lower part of the connecting component. Two limiting flower-shaped blocks are provided, which are symmetrically installed at the upper and lower ends of the central column of the connecting component based on the connecting shaft. A gear shaft, two irregularly shaped shafts protruding outward on both sides, and a reset component are provided inside the column. The gear shaft is located within the rotation limiting area and meshes with the operating gear. The irregularly shaped shaft passes through the reset area at both ends of the rotation limiting area and is fixedly connected to the connecting shaft. The reset area is connected to the rotation limiting area.

[0004] In the existing compensation chain installation structure, the compensation chain is simply suspended on the U-shaped frame by a stop. During elevator operation, the compensation chain will sway on the U-shaped frame, which will cause continuous friction, resulting in metal friction noise and wear on the inner wall of the U-shaped frame.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create an elevator compensation chain mounting bracket structure that would have greater industrial application value. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an elevator compensation chain mounting bracket structure.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] The first embodiment of this utility model:

[0036] like Figure 1 The elevator compensation chain mounting bracket structure of this embodiment mainly includes a car 1, a compensation chain 2, a suspension mounting component 3, and a clamping component 4.

[0037] The suspension mounting assembly 3 for suspending the compensation chain 2 is installed at the bottom of the car 1. A clamping assembly 4 is also installed at the bottom of the car 1 to clamp the top of the suspended compensation chain 2.

[0038] like Figure 2 The suspension mounting component 3 mainly includes a U-shaped suspension bracket 31, which includes an arc-shaped end located in the middle of the bottom and straight ends located on the left and right sides.

[0039] The tops of the straight ends on both sides of the U-shaped suspension frame 31 pass through the first through hole 5 at the bottom of the car 1 and are then locked by the locking nut 33. The locking nut 33 is threadedly connected to the threaded ends on the straight ends on both sides of the U-shaped suspension frame 31. Then the compensation chain 2 is suspended on the arc-shaped end at the bottom of the U-shaped suspension frame 31.

[0040] Among them, a lower support block 32 is installed at the straight ends on both sides of the U-shaped suspension bracket 31 and at the position below the first through hole 5, and the bottom is limited by the lower support block 32.

[0041] like Figure 3 and Figure 4 The clamping assembly 4 mainly includes a clamping mechanism 41, a sliding ring 42, an adjusting frame 43, and a guide rod 45. The clamping mechanism 41 mainly includes a clamping block 411.

[0042] A clamping groove 412 is provided at the bottom center of the clamping block 411. The clamping groove 412 is an arc-shaped structure that protrudes upwards and contacts the top of the compensation chain 2 below.

[0043] Sliding rings 42 are installed on both the left and right sides of the clamping block 411. The sliding rings 42 can slide vertically on the straight ends of the U-shaped suspension frame 31 on both the left and right sides, thereby adjusting the height of the clamping block 411.

[0044] An adjusting frame 43 is installed on the outside of the sliding ring 42. A guide rod 45 distributed vertically is installed on the top of the adjusting frame 43. The guide rod 45 can move a certain distance vertically within the second through hole 6 opened on the bottom of the car 1. A handle 44 is installed at the bottom of the adjusting frame 43. The above-mentioned movement and adjustment process can be completed by holding the handle 44, so that the pressing groove 412 can press the top of the compensation chain 2 and release the above-mentioned pressing process.

[0045] In order to limit the movement of the guide rod 45, an upper limit block 46 and a lower limit block 47 are installed on the guide rod 45 from top to bottom. The upper limit block 46 is designed on the guide rod 45 and located on the side above the second through hole 6, and the lower limit block 47 is designed on the guide rod 45 and located on the side below the second through hole 6.

[0046] In order to buffer the movement of the guide rod 45, a spring 48 is installed on the guide rod 45 between the second through hole 6 and the lower limit block 47. The compression and relaxation of the spring 48 provide a certain buffering effect.

[0047] The second embodiment of this utility model:

[0048] like Figure 4 In order to ensure that the clamping block 411 is in the lowest position under normal conditions, thereby clamping the top of the compensation chain 2, multiple mass blocks 415 can be installed inside the clamping block 411.

[0049] Specifically, an installation cavity 414 is provided on the inner side of the top of the clamping block 411. Multiple mass blocks 415 are arranged in a certain direction in the installation cavity 414 to increase the overall weight of the clamping block 411.

[0050] Furthermore, the clamping treatment of the compensation chain 2 of different specifications can be adapted by increasing or decreasing the mass block 415 located in the mounting cavity 414.

[0051] In addition, a sealing plate 413 is installed on the clamping block 411 on the outer side above the mounting cavity 414. The sealing plate 413 can be installed on the clamping block 411 by bolts.

[0052] The third embodiment of this utility model:

[0053] A rubber layer, a high-temperature resistant layer, and a wear-resistant layer are sequentially arranged from the inside to the outside on the pressing groove 412.

[0054] The rubber layer is made of rubber materials such as rubber pads or rubber sleeves.

[0055] The high-temperature resistant layer is a polyphenylene sulfide coating or similar material applied to the outside of the rubber layer, which gives the inner rubber layer better high-temperature resistance and reduces damage to the rubber layer caused by high temperatures.

[0056] The wear-resistant layer is a polyamide coating, which has good wear resistance. Additionally, a Teflon coating can be applied to the outside of the polyamide coating. Teflon coatings have good thermal stability, allowing them to adapt to both low and high temperature environments, and also exhibit good wear resistance.

[0057] An insulation layer and an anti-oxidation layer are sequentially arranged from the inside to the outside on the compensation chain 2.

[0058] The insulation layer is an aerogel felt layer, which enables the compensation chain 2 to have good performance in low-temperature environments.

[0059] The anti-oxidation layer is a graphite electrode anti-oxidation coating, which gives the compensation chain 2 good anti-oxidation performance, avoids its own oxidation damage, and improves its service life.
