Description

Technical Field

[0001] The utility model relates to the technical field of elevator balance compensation chains, in particular to an elevator balance compensation chain with a noise reduction function. Background Technique

[0002] During the use of the compensation chain, it may become loose or worn due to long-term operation, resulting in friction or collision between the chain and surrounding components, thus generating noise. Therefore, an elevator balance compensation chain with a noise reduction function is one of the important directions in the development of elevator technology. The elevator balance compensation chain with a noise reduction function can reduce the noise generated during the operation of the elevator and improve the riding experience of passengers.

[0003] In the existing publicly disclosed technical solution, the publication number CN213864930U discloses an elevator balance compensation chain with a noise reduction function, including a main body, a reinforcement layer, and a protective layer. The reinforcement layer is installed on the outer side of the main body, and the protective layer is installed on the outer side of the reinforcement layer. One end inside the protective layer is installed with a flame retardant layer, and one end of the flame retardant layer is installed with a buffer layer. One end of the buffer layer is installed with a sound absorption layer, and one end of the sound absorption layer is installed with a wear-resistant layer. It is made of wear-resistant material, buffer material, and flame retardant material inside the protective layer, which plays a certain protective role for the main body and prolongs the service life of the main body. The sound absorption layer is made of sound absorption material, which can reduce the noise generated by the main body hitting the guiding structure to a certain extent and achieve the effect of noise reduction.

[0004] When the above technical solution is actually implemented, since the protective layer is located outside the iron chain, the protective layer will inevitably wear during use. The worn protective layer greatly reduces the noise reduction ability of the elevator balance compensation chain, and a new elevator balance compensation chain needs to be replaced in time. It may cause damage to the external protective layer, while the internal iron chain remains intact, and it is not convenient to disassemble between the protective layer and the iron chain. If the complete elevator balance compensation chain is replaced, the cost is too high, and it is not convenient to only replace the external protective layer. Summary of the Invention

[0005] The purpose of the utility model is to provide an elevator balance compensation chain with a noise reduction function, which can reduce the maintenance cost by directly replacing the protective noise reduction shell, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an elevator balance compensation chain with a noise reduction function, including a protective noise reduction shell, a plastic-coated pipe is penetrated inside the protective noise reduction shell, and an iron chain main body is fixed inside the plastic-coated pipe. Both ends of the iron chain main body penetrate through the plastic-coated pipe, and a limiting block is arranged on the surface of the plastic-coated pipe;

[0007] Both the upper and lower ends of the protective and noise-reducing housing are provided with limit connection components for positioning. One set of the limit connection components includes two connection bases in a semi-circular ring structure. The inner wall of the connection base is provided with a limit groove adapted to the limit block, and fixed ear plates are fixedly arranged at both the left and right ends of the connection base. Two fixing holes are provided inside the fixed ear plate, and fixing screws are inserted through the fixing holes.

[0008] Preferably, the protective and noise-reducing housing includes a woven layer, an anti-corrosion layer, a sound-absorbing cotton layer, and a rubber layer, which are arranged in sequence from outside to inside.

[0009] Preferably, the protective and noise-reducing housing is of a tubular structure, and the protective and noise-reducing housing is movably connected to the connection base.

[0010] Preferably, the woven layer is made of nylon material, and the woven layer, the anti-corrosion layer, the sound-absorbing cotton layer, and the rubber layer are adhesively connected to each other in pairs.

[0011] Preferably, the two connection bases are detachably connected through the fixed ear plates, the fixing holes, and the fixing screws, and the connection base and the fixed ear plate are integrally formed.

[0012] Preferably, the connection base is engaged with the limit block through the limit groove, and the outer dimensions of the limit groove and the limit block are adapted to each other.

[0013] Preferably, the inner diameter of the protective and noise-reducing housing is equal to the outer diameter of the limit block, and the outer diameter of the protective and noise-reducing housing is equal to the outer diameter of the connection base.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By movably connecting the protective and noise-reducing housing with the plastic-coated pipe, when the noise-reducing effect of the protective and noise-reducing housing decreases due to wear during long-term use, the protective and noise-reducing housing can be directly replaced, reducing the maintenance cost, and the internal plastic-coated pipe and the iron chain body can still be used.

[0016] 2. By providing the limit connection components, the connection base can be directly clamped outside the limit block of the plastic-coated pipe, thereby preventing the protective and noise-reducing housing from shifting and keeping the protective and noise-reducing housing between the two sets of limit connection components.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 in 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.

[0025] The present utility model provides a technical solution:

[0026] Please refer to Figures 1 to 4 , a kind of elevator balance compensation chain with noise reduction function, which includes a noise-proof and shock-absorbing housing 1. A plastic-coated pipe 4 is penetrated inside the noise-proof and shock-absorbing housing 1, and a main body of iron chain 3 is fixed inside the plastic-coated pipe 4. Both ends of the main body of iron chain 3 penetrate through the plastic-coated pipe 4, and a limit block 5 is arranged on the surface of the plastic-coated pipe 4;

[0027] Limit connection assemblies 2 for positioning are arranged at both the upper and lower ends of the noise-proof and shock-absorbing housing 1. A set of limit connection assemblies 2 includes two semi-circular connection bases 201. A limit groove 202 adapted to the limit block 5 is opened on the inner wall of the connection base 201, and fixed ear plates 203 are fixedly arranged at both the left and right ends of the connection base 201. Two fixed holes 204 are opened inside the fixed ear plates 203, and fixed screws 205 are penetrated inside the fixed holes 204;

[0028] Two sets of connecting bases 201 are detachably connected through fixing lugs 203, fixing holes 204 and fixing screws 205. The connecting base 201 and the fixing lug 203 are integrally formed. The connecting base 201 is engaged with the limiting block 5 through the limiting groove 202, and the outer dimensions of the limiting groove 202 and the limiting block 5 are adapted to each other.

[0029] By adopting the above technical solution, since the protective and noise-reducing housing 1 is movably connected to the plastic-coated pipe 4, when the noise-reducing effect of the protective and noise-reducing housing 1 is reduced due to wear during long-term use, the protective and noise-reducing housing 1 can be directly replaced, reducing the maintenance cost, and the internal plastic-coated pipe 4 and the iron chain body 3 can still be used. In order to prevent the protective and noise-reducing housing 1 from sliding on the plastic-coated pipe 4, the protective and noise-reducing housing 1 is located between two sets of limiting connection components 2, and the limiting connection components 2 directly clamp the outer part of the limiting block 5 of the plastic-coated pipe 4 through the connecting base 201, thereby preventing the protective and noise-reducing housing 1 from shifting.

[0030] Specifically, as Figure 4 shown, the protective and noise-reducing housing 1 includes a woven layer 101, an anti-corrosion layer 102, a sound-absorbing cotton layer 103 and a rubber layer 104. The woven layer 101, the anti-corrosion layer 102, the sound-absorbing cotton layer 103 and the rubber layer 104 are arranged in sequence from outside to inside. The protective and noise-reducing housing 1 is a tubular structure, and the protective and noise-reducing housing 1 is movably connected to the connecting base 201. The woven layer 101 is made of nylon material, and the woven layer 101, the anti-corrosion layer 102, the sound-absorbing cotton layer 103 and the rubber layer 104 are adhesively connected to each other. The inner diameter of the protective and noise-reducing housing 1 is equal to the outer diameter of the limiting block 5, and the outer diameter of the protective and noise-reducing housing 1 is equal to the outer diameter of the connecting base 201.

[0031] By adopting the above technical solution, since the rubber layer 104 is arranged inside the protective and noise-reducing housing 1, when the plastic-coated pipe 4 collides with the rubber layer 104, the generated noise is small, and it plays a certain buffering role for the plastic-coated pipe 4. The sound-absorbing cotton layer 103 can absorb sound and reduce noise. Cooperating with the woven layer 101 and the anti-corrosion layer 102, the corrosion resistance and wear resistance of the protective and noise-reducing housing 1 can be improved.

[0032] Working principle: When the protective and noise-reducing housing 1 needs to be replaced, rotate the fixing screw 205 to separate the fixing screw 205 from the fixing hole 204, so that the two fixing lugs 203 are separated from each other, and the connecting base 201 is disassembled, then the protective and noise-reducing housing 1 can be pulled out. When the noise-reducing effect of the protective and noise-reducing housing 1 is reduced due to wear during long-term use, the protective and noise-reducing housing 1 can be directly replaced, reducing the maintenance cost, and the internal plastic-coated pipe 4 and the iron chain body 3 can still be used. In order to prevent the protective and noise-reducing housing 1 from sliding on the plastic-coated pipe 4, the protective and noise-reducing housing 1 is located between two sets of limiting connection components 2, and the limiting connection components 2 directly clamp the outer part of the limiting block 5 of the plastic-coated pipe 4 through the connecting base 201, thereby preventing the protective and noise-reducing housing 1 from shifting.

[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.
