Description

Technical Field

[0001] This utility model relates to the field of elevator balance compensation chain technology, and in particular to a fixing device for elevator balance compensation chain. Background Technology

[0002] The compensating chain primarily functions to compensate for the weight of the traction steel wire rope, balancing the weight difference caused by changes in the position of the wire rope during elevator operation. When the elevator is on the top floor, most of the weight of the wire rope is on the counterweight side; when the elevator is on the bottom floor, most of the weight of the wire rope is on the car side. To balance this weight change, the compensating chain moves with the elevator. When the wire rope moves towards the counterweight side, the compensating chain moves with the car to compensate; when the wire rope moves towards the car side, the compensating chain moves with the counterweight towards the counterweight side.

[0003] With the increasing demand for elevators with large lifting heights, the length of elevator steel cables is getting longer and longer, and the weight of the compensating chain will also increase accordingly. Although the elevator compensating chain fixing method is equipped with secondary protection, the compensating chain will inevitably twist and sway during elevator operation, which may lead to the failure of the compensating chain breaking when the elevator is moving up and down.

[0004] An existing patent (publication number: CN217024925U) discloses an elevator compensation chain self-balancing device. When measurement is required, the elevator compensation chain self-balancing device of this utility model can automatically adjust the lateral position of the compensation chain at the bottom of the elevator car or the bottom of the elevator counterweight by installing a balancing component at the bottom of the elevator car or the bottom of the elevator counterweight. The change in the mass of the compensation chain on the car side caused by the change in the length of the compensation chain during elevator operation can be adjusted by compressing the left or right spring, thereby automatically adjusting the mass on one side of the car.

[0005] To address the aforementioned issues, while existing patents offer solutions that can compensate for weight and automatically adjust balance through components such as a left spring, in practical use, the method of connecting the compensation chain relies on the cooperation of a sliding rod and a sleeve rod for support. Due to the weight of the compensation chain, it may become difficult to provide support over time. Summary of the Invention

[0006] The purpose of this utility model is to provide a fixing device for an elevator balance compensation chain, which can disperse the force and avoid excessive force concentration that would cause excessive tension on the components, thereby affecting the stability of the compensation chain when adjusting with the elevator or causing damage to the components. At the same time, the first spring can play a buffering role to avoid collisions, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fixing device for an elevator balance compensation chain, comprising a bearing plate, wherein a bearing rod is fixedly installed on the axial outer wall of the bearing plate, and an adjustment mechanism is provided on one side of the bearing rod;

[0008] The adjusting mechanism includes a slider, which is slidably connected to the outside of the bearing rod. A connecting rod is embedded at the front end of the slider. A rotating block is rotatably connected to the outer wall of the connecting rod. A rotating head is movably connected to the front end of the rotating block. A fixing rod is fixedly installed at the front end of the rotating head. An installation plate is fixedly installed at the front end of the fixing rod. A support rod is fixedly installed on the outer wall of the installation plate. A first spring is sleeved on the outside of the support rod.

[0009] Preferably, a support frame is sleeved on one side of the first spring outside the support rod, and a fixed end is fixedly installed at the bottom of the support frame.

[0010] Preferably, the support rod extends through the interior of the support frame, and a sliding structure is formed between the support frame and the support rod.

[0011] Preferably, the top of the support frame is fitted with a threaded cap, and the inside of the support frame is provided with a lubrication mechanism.

[0012] Preferably, the support frame includes through holes, which are opened on both sides of the outer wall of the support frame, and the interior of the support frame is filled with sponge.

[0013] Preferably, a pressing plate is fixedly installed on one side of the sponge, and a rubber pad is embedded in the outer wall of the pressing plate away from the sponge. A second spring is fixedly installed on the end of the pressing plate facing the sponge, and an abutment rod is fixed on one side of the support rod on the outer wall of the mounting plate.

[0014] Preferably, the pressing plate forms a spring structure with the support frame via a second spring, and the second spring extends into the interior of the sponge.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses the cooperation of the support frame and the fixed end, and four sets of steel wire ropes to fix the compensation chain, thereby dispersing the force and avoiding excessive force concentration that would cause excessive tension on the components, thus affecting the stability of the compensation chain when adjusting with the elevator, or causing damage to the components. At the same time, the first spring can play a buffering role to prevent collisions.

[0017] 2. This utility model uses a sponge to impregnate the lubricating oil, which, when the support frame moves, is pressed by the pressing plate to lubricate the support rod, preventing excessive friction and jamming during the sliding process of the support frame, thus affecting the stability of the compensation chain. Furthermore, when the compensation chain is adjusted to the bottom side of the elevator via the elevator, it supports the support frame through the abutment rod, thereby increasing the load-bearing capacity.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 3 A fixing device for an elevator balance compensation chain includes a bearing plate 1, a bearing rod 2 fixedly installed on the axial outer wall of the bearing plate 1, and an adjustment mechanism 3 provided on one side of the bearing rod 2. The adjustment mechanism 3 includes a slider 301, which is slidably connected to the outside of the bearing rod 2. A connecting rod 302 is embedded at the front end of the slider 301. A rotating block 303 is rotatably connected to the outer wall of the connecting rod 302. A rotating head 304 is movably connected to the front end of the rotating block 303. A fixing rod 305 is fixedly installed at the front end of the rotating head 304. An installation plate 306 is fixedly installed at the front end of the fixing rod 305. A support rod 307 is fixedly installed on the outer wall of the installation plate 306. A first spring 308 is sleeved on the outside of the support rod 307. A bearing frame 309 is sleeved on one side of the first spring 308 outside the support rod 307. A fixing end 310 is fixedly installed at the bottom end of the bearing frame 309. The support rod 307 penetrates into the interior of the bearing frame 309, and a sliding structure is formed between the bearing frame 309 and the support rod 307.

[0028] By adopting the above technical solution, the slider 301 can drive the connecting rod 302 to slide under the support of the bearing plate 1 and the bearing rod 2. With the cooperation of the rotating block 303 and the rotating head 304, the fixed rod 305 can drive the mounting plate 306, thereby allowing the two support rods 307 to support the bearing frame 309. The four fixed ends 310 are connected to the compensation chain by four sets of steel wire ropes, which improves the connection stability and allows the chain to move flexibly according to the force of the compensation chain while maintaining the stability and load-bearing capacity. The first spring 308 is sleeved on the outside of the support rod 307, which can play a buffering role when the bearing frame 309 slides due to the influence of the compensation chain.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a threaded cap 4 is fitted at the top of the support frame 309, and a lubrication mechanism 5 is provided inside the support frame 309. The support frame 309 includes a through hole 501, which is opened on both sides of the outer wall of the support frame 309. A sponge 502 is embedded inside the support frame 309. A pressing plate 503 is fixedly installed on one side of the sponge 502. A rubber pad 504 is embedded on the outer wall of the pressing plate 503 away from the sponge 502. A second spring 505 is fixedly installed on the end of the pressing plate 503 facing the sponge 502. An abutment rod 506 is fixed on one side of the support rod 307 on the outer wall of the mounting plate 306. The pressing plate 503 and the support frame 309 form a spring structure through the second spring 505. The second spring 505 penetrates into the interior of the sponge 502.

[0030] By adopting the above technical solution, lubricating oil is first injected into the support frame 309 periodically by disassembling and assembling the threaded cover 4, and the sponge 502 is soaked. When the support frame 309 moves to a certain position, the abutting rod 506 is inserted into the support frame 309 through the through hole 501 and abuts against the rubber pad 504, causing the pressing plate 503 to compress the second spring 505 and the sponge 502 at the same time. The squeezed-out lubricating oil can be coated on the support rod 307 for lubrication, which can prevent excessive friction and jamming during the movement of the support frame 309. At the same time, when it is close to the bottom of the elevator, the abutting rod 506 can further support the support frame 309 and maintain its stability. When the support frame 309 is away from the bottom of the elevator, the pressing plate 503 can be reset by the second spring 505, so that the rubber pad 504 can prevent the through hole 501 from leaking lubricating oil.

[0031] Working principle: The bearing plate 1 and bearing rod 2 can be fixed to the bottom of the car or the counterweight. The connecting rod 302 slides along the bearing rod 2 via the slider 301. The rotating block 303 sleeved on the outer wall of the connecting rod 302 is movably connected to the fixed rod 305 via the rotating head 304. The front end support rod 307 of the mounting plate 306 fixed to the fixed rod 305 is slidably connected to the bearing frame 309, thereby stably supporting the bearing frame 309. The bearing frame 309 is fixed with steel wire ropes through four fixed ends 310. The other ends of the four sets of steel wire ropes are simultaneously fixed to the compensating chain to improve the connection stability. When the bearing frame 309 slides along the support rod 307 under the guidance of the compensating chain, it is guided by the first spring 30 8. The elastic abutment provides cushioning. The threaded cap 4 is threadedly connected to the support frame 309, facilitating periodic disassembly and reassembly. After that, lubricating oil is injected to wet the sponge body 502. When the support frame 309 slides to a certain position, the abutment rod 506 is inserted into the through hole 501, abutting the rubber pad 504 and the pressing plate 503, thereby compressing the sponge body 502 and squeezing out the lubricating oil to coat the support rod 307, thus keeping the support frame 309 lubricated during the sliding process. The second spring 505 can reset the pressing plate 503 when the abutment rod 506 is disengaged from the support frame 309. The rubber pad 504 can seal the through hole 501 to prevent the lubricant from flowing out when the abutment rod 506 is not inserted.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
