Technical Field

[0001] The utility model relates to the technical field of elevator balancing and compensating chains, in particular to a self-lubricating elevator balancing and compensating chain. Background Art

[0002] The elevator compensation chain is a transmission chain connecting the elevator running platform and the compensation weight. Lubrication can reduce the friction between the chains, thereby reducing the wear and aging rate. If the compensation chain is not lubricated, it will accelerate the wear and aging of the chain, reduce the safety factor of the elevator, and even cause elevator failure. Good lubrication can extend the service life of the compensation chain, reduce the frequency of replacement due to wear, and reduce maintenance costs.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a technical solution:

[0028] Please refer to Figures 1 to 4 , a self-lubricating type elevator balance compensation chain, including a protective cover 1, an oil supply assembly 6 for supplying lubricating oil is arranged inside the protective cover 1, and lubricating assemblies 5 for applying lubricating oil are arranged on both the upper and lower sides of the oil supply assembly 6, and a compensation chain 4 is penetrated through the interiors of the oil supply assembly 6 and the lubricating assemblies 5;

[0029] The lubricating assembly 5 includes a lubricating cylinder 501 slidably installed inside the protective cover 1, and a lubricating brush 502 that fits the surface of the compensation chain 4 is arranged on the inner wall of the lubricating cylinder 501;

[0030] The oil supply assembly 6 includes an oil storage cylinder 601, rubber plates 603 are arranged at both the top and bottom ends of the oil storage cylinder 601, a pressure rod 605 that penetrates through the oil storage cylinder 601 is arranged at the end of the rubber plate 603, a plug 602 is arranged at the end of the pressure rod 605, a support spring 604 is installed between the plug 602 and the oil storage cylinder 601, and an oil outlet hole 606 is opened on the inner wall of the oil storage cylinder 601.

[0031] By adopting the above technical solution, the compensation chain 4 is installed at the bottoms of the car and the counterweight. When the car runs, it can pull the protective sleeve 1 to move. While the protective sleeve 1 is moving, under the action of gravity, the lubricating component 5 will move between the protective sleeve 1 and the compensation chain 4. When the lubricating component 5 approaches the oil supply component 6, the lubricating cylinder 501 of the lubricating component 5 is closely attached to the oil storage cylinder 601, so that the oil storage cylinder 601 and the rubber plate 603 are pressed against each other. At this time, the rubber plate 603 moves in the direction close to the oil storage cylinder 601, and drives the support spring 604 to stretch through the pressure rod 605, so that the plug 602 moves away from the oil outlet 606, and lubricating oil can flow out at the oil outlet 606. The lubricating oil flows into the protective sleeve 1 along the oil storage cylinder 601 to lubricate the compensation chain 4. As the car moves and the lubricating component 5 slides, the lubricating oil is brushed onto the compensation chain 4 by the lubricating brush 502. Since the lubricating oil is stored in the oil storage cylinder 601 inside the protective sleeve 1, even if the protective sleeve 1 is worn, as long as the lubricating oil flows out from the inside of the oil storage cylinder 601, the compensation chain 4 can be lubricated through the movement of the lubricating component 5.

[0032] Specifically, as Figure 4 shown, the oil outlet 606 is closely attached to the plug 602, and the plug 602 is adapted to the inner cavity size of the oil storage cylinder 601. The plug 602 is elastically connected to the oil storage cylinder 601 through the support spring 604, and the pressure rod 605 penetrates through the inside of the support spring 604. The diameter of the rubber plate 603 is larger than the diameter of the pressure rod 605. There are four groups of plugs 602. One side of the oil supply component 6 is provided with an oil supply port communicating with the protective sleeve 1, and a sealing head 2 is threadedly connected to the oil supply port. Welding bases 3 are fixedly arranged at both the upper and lower ends of the protective sleeve 1, and the compensation chain 4 penetrates through the inside of the welding base 3. There are two groups of lubricating components 5, and the oil supply component 6 is fixed in the middle inside the protective sleeve 1.

[0033] By adopting the above technical solution, the elastic force of the support spring 604 is greater than the inertial force of the rubber plate 603, the pressure rod 605 and the plug 602 when the car moves, so as to prevent the plug 602 from being separated from the oil outlet 606 directly under the inertial action when the car moves. Only when the lubricating component 5 presses against the oil supply component 6, will the lubricating oil flow out. And the welding base 3 protects both ends of the compensation chain 4. The ends of the compensation chain 4 can be directly connected to the car and the counterweight through hooks, which is convenient for installing the compensation chain 4. The lubricating brush 502 can be a soft brush to brush the lubricating oil on the compensation chain 4.

[0034] Working principle: The compensation chain 4 is installed at the bottom of the car and the counterweight. When the car runs, it can pull the protective sleeve 1 to move. While the protective sleeve 1 is moving, under the action of gravity, the lubricating component 5 will move between the protective sleeve 1 and the compensation chain 4. When the lubricating component 5 approaches the oil supply component 6, the lubricating cylinder 501 of the lubricating component 5 is closely attached to the oil storage cylinder 601, so that the oil storage cylinder 601 and the rubber plate 603 are pressed against each other. At this time, the rubber plate 603 moves towards the oil storage cylinder 601, and drives the support spring 604 to stretch through the pressure rod 605, so that the plug 602 moves away from the oil outlet 606. Lubricating oil can flow out at the oil outlet 606, and the lubricating oil flows into the protective sleeve 1 along the oil storage cylinder 601 to lubricate the compensation chain 4. As the car moves and the lubricating component 5 slides, the lubricating oil is brushed onto the compensation chain 4 through the lubricating brush 502. Since the lubricating oil is stored in the oil storage cylinder 601 inside the protective sleeve 1, even if the protective sleeve 1 is worn, as long as the lubricating oil flows out from the inside of the oil storage cylinder 601, through the movement of the lubricating component 5, the compensation chain 4 can also be lubricated.

[0035] 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.
