Description

Technical Field

[0001] The utility model relates to the technical field of dip - molded balance chains, in particular to a dip - molded balance compensation chain that is convenient for reducing wear effect. Background Technique

[0002] During the operation of an elevator, the lengths of the steel ropes on the car side and the counterweight side are constantly changing, thus causing changes in the weights of the steel ropes on both sides of the traction sheave. When the elevator's lifting height is not large, this change has little impact on the elevator's operating performance. However, when the lifting height exceeds a certain level, it will seriously affect the stability of the elevator operation and endanger the safety of passengers. Therefore, when the elevator's lifting height exceeds a certain height, it is necessary to set up components with a certain weight to balance the weight change caused by the height change, which is the elevator balance compensation chain.

[0003] When operating in an elevator system, the balance compensation chain will be exposed to harsh environments such as humidity and corrosive gases for a long time. Dip - molding treatment can form a protective layer on the surface of the compensation chain, effectively isolating the erosion of the external environment on the compensation chain body, thereby improving its corrosion resistance.

[0004] When the balance compensation chain runs at high speed, it will oscillate or swing. In order to reduce the swing of the compensation chain, a guiding device is installed in the pit, and the guiding device is usually directly fixed in the pit by bolts, which is not convenient for shifting and adjusting the guiding device.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4 , a dip-molded balance compensating chain that is convenient for reducing wear effect, including a compensating chain body 1. A first guiding assembly 3 for guiding is provided at the bottom of the compensating chain body 1, and a second guiding assembly 4 having the same structure as the first guiding assembly 3 is provided on one side of the first guiding assembly 3. A fixed bottom plate 2 for supporting is provided below the second guiding assembly 4 and the first guiding assembly 3. A shifting assembly 5 for adjusting the positions of the second guiding assembly 4 and the first guiding assembly 3 is provided on the fixed bottom plate 2;

[0028] The displacement assembly 5 includes a guiding slider 503 fixed below the support frame 301. A guiding chute 501 is provided at the connection between the guiding slider 503 and the fixed base plate 2. An adjusting lead screw 502 is installed inside the guiding slider 503 through a lead screw sleeve. The displacement assembly 5 further includes an adjusting bevel gear 504 installed at one end of the adjusting lead screw 502, and the other end of the adjusting lead screw 502 is installed inside the fixed base plate 2 through a bearing. A transmission bevel gear 505 is meshed and connected to one side of the adjusting bevel gear 504, and an output shaft 506 is fixedly provided in the middle of the transmission bevel gear 505. One end of the output shaft 506 is installed inside the fixed base plate 2 through a bearing, and the other end of the output shaft 506 is connected to an output bevel gear 507. An active bevel gear 508 is meshed and connected to one side of the output bevel gear 507, and the power output end of a servo motor 509 is installed in the middle of the active bevel gear 508. The servo motor 509 is fixedly installed above the fixed base plate 2 through bolts.

[0029] By adopting the above technical solution, when it is necessary to adjust the positions of the first guiding assembly 3 and the second guiding assembly 4, the servo motor 509 can be started. The power output end of the servo motor 509 drives the active bevel gear 508 to rotate, thereby driving the output bevel gear 507 to rotate through the active bevel gear 508. The output bevel gear 507 drives the two groups of transmission bevel gears 505 to rotate synchronously through the output shaft 506. The adjusting bevel gear 504 meshed with the transmission bevel gear 505 can rotate synchronously, so that the adjusting lead screw 502 on the adjusting bevel gear 504 rotates. Furthermore, under the action of the lead screw sleeve, the guiding slider 503 is driven to slide in the guiding chute 501, thereby adjusting the distance between the two support frames 301 on the first guiding assembly 3 and the second guiding assembly 4. Thus, the positions of the guiding assemblies can be conveniently adjusted according to the position of the car.

[0030] Specifically, as Figure 2 shown, both the first guiding assembly 3 and the second guiding assembly 4 include a support frame 301. A guiding plate 303 is arranged inside the support frame 301. A rubber plate 304 is adhered to the inner side of the guiding plate 303. A guiding rod 302 is installed between the two guiding plates 303 through a bearing. Both the first guiding assembly 3 and the second guiding assembly 4 are provided with two groups. The first guiding assembly 3 and the second guiding assembly 4 can move towards each other on the fixed base plate 2 respectively through the displacement assembly 5. The distance between the guiding plates 303 on the first guiding assembly 3 and the second guiding assembly 4 is smaller than the diameter of the compensation chain body 1. The compensation chain body 1 passes through between the first guiding assembly 3 and the second guiding assembly 4;

[0031] By adopting the above technical solution, the compensation chain body 1 is threaded between the guide rods 302 of the first guide assembly 3 and the second guide assembly 4, and the other end passes out between the guide rods 302 of the first guide assembly 3 and the second guide assembly 4 on the other side. At this time, the compensation chain body 1 is located in the space formed by the guide rods 302 on the first guide assembly 3 and the second guide assembly 4 and the guide plates 303 on the first guide assembly 3 and the second guide assembly 4. When the compensation chain body 1 moves, it is restricted within the guide space. The guide rods 302 can be set as rubber rods, so as to reduce the noise generated by the collision between the compensation chain body 1 and the first guide assembly 3 and the second guide assembly 4. At the same time, the guide rods 302 can rotate on the guide plates 303, reducing the friction between the compensation chain body 1 and the first guide assembly 3 and the second guide assembly 4, thereby reducing the wear of the compensation chain body 1 caused by collision.

[0032] Working principle: The inner chain links of the compensation chain body 1 can be treated by dip coating process on the outside to improve the overall performance of the compensation chain body 1. The compensation chain body 1 is threaded between the guide rods 302 of the first guide assembly 3 and the second guide assembly 4, and the other end passes out between the guide rods 302 of the first guide assembly 3 and the second guide assembly 4 on the other side. At this time, the compensation chain body 1 is located in the space formed by the guide rods 302 on the first guide assembly 3 and the second guide assembly 4 and the guide plates 303 on the first guide assembly 3 and the second guide assembly 4. When the compensation chain body 1 moves, it is restricted within the guide space. The power output end of the servo motor 509 drives the driving bevel gear 508 to rotate, thereby driving the output bevel gear 507 to rotate through the driving bevel gear 508. The output bevel gear 507 drives two groups of transmission bevel gears 505 to rotate synchronously through the output shaft 506. The adjusting bevel gear 504 engaged with the transmission bevel gear 505 can rotate synchronously, so that the adjusting screw rod 502 on the adjusting bevel gear 504 rotates. Then, under the action of the screw rod sleeve, the guide slider 503 slides in the guide chute 501, thereby adjusting the distance between the two support frames 301 on the first guide assembly 3 and the second guide assembly 4. Thus, it is convenient to adjust the position of the guide assembly according to the position of the car.

[0033] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
