Description

Technical Field

[0001] This utility model belongs to the field of elevator component technology, specifically relating to a double shock absorption structure for a household elevator pulley. Background Technology

[0002] With the increasing popularity of home elevators, users have higher and higher requirements for ride comfort. Vibration and noise during elevator operation are the main factors affecting comfort. Vibration is mainly transmitted to the car through the main unit, guide rails, and wire ropes. Currently, rubber vibration damping pads are used in the car frame structure of home elevators to isolate vibration and reduce noise. However, when the elevator speed increases, its vibration isolation effect decreases, and vibration can easily be transmitted from the sheaves to the car frame and then to the car, causing resonance. Common vibration damping measures are mainly set between the main unit and the base, between the bracket and the car bottom, between the car frame and the wire ropes, and between the sheaves and the car frame.

[0003] However, existing technologies typically use only a simple single-layer rubber pad for vibration transmission between the sheave and the car frame. As elevator speed increases, the high-frequency vibration of the wire rope and the rotational vibration of the sheave are directly transmitted to the upper beam of the car frame through the rigidly connected sheave seat, easily causing car resonance, leading to decreased vibration isolation and increased noise. Therefore, a new type of vibration damping structure that can effectively isolate the transmission of sheave vibration is urgently needed. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a double shock-absorbing structure for a home elevator pulley, which is specifically achieved through the following technical solution: A dual shock absorption structure for a home elevator sheave is disclosed. This dual shock absorption structure is a dual shock absorption pad assembly installed between the sheave seat and the upper beam plate of the elevator frame. The dual shock absorption pad assembly includes an upper base plate, an intermediate clamping plate, a lower base plate, and rubber blocks. The intermediate clamping plate is disposed between the upper base plate and the lower base plate, and the rubber blocks are disposed between the intermediate clamping plate and the upper base plate, as well as between the intermediate clamping plate and the lower base plate. Thus, the two outer base plates are bonded to the upper and lower surfaces of the intermediate clamping plate through the rubber blocks, ultimately forming a stable "sandwich" type layered shock absorption result.

[0005] Furthermore, at least one set of the dual shock-absorbing pad assembly is provided, and multiple rubber blocks are provided.

[0006] Furthermore, to prevent excessive shear deformation of the damping block under stress, which could cause the sheave to tilt, a limiting hole is made on the double damping pad assembly. A limiting bolt is inserted into the limiting hole, and the limiting bolt passes through the limiting hole and the upper beam of the car frame in sequence to limit the radial displacement of the double damping pad assembly.

[0007] Furthermore, each set of dual shock-absorbing pads is provided with four rubber blocks, which are symmetrically distributed at the four corners of the middle clamping plate.

[0008] Furthermore, the rubber block is bonded and fixed to the intermediate clamping plate, the upper base plate, and the lower base plate by an adhesive.

[0009] Furthermore, 4-8 sets of double shock-absorbing pad assemblies are installed between the sheave seat and the upper beam of the car frame.

[0010] This utility model forms two vibration attenuation barriers through the setting of a double shock-absorbing pad assembly, which has a good isolation effect on medium and high frequency vibrations. The middle clamping plate evenly distributes the force to the four rubber blocks, avoiding stress concentration and effectively preventing the rubber blocks from tearing or undergoing permanent deformation due to long-term impact, thus extending their service life. The matching design of the limiting hole and the limiting bolt provides flexible shock absorption while ensuring the verticality and stability of the rope wheel system, ensuring safe operation.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings to provide a better understanding of the technical solution.

[0013] like Figure 1-2 As shown, this utility model discloses a double shock-absorbing structure for a household elevator pulley. The double shock-absorbing structure consists of a double shock-absorbing pad assembly 2 installed between the pulley seat 1 and the upper beam plate of the elevator frame. At least one set of the double shock-absorbing pad assembly 2 is provided, preferably 4-8 sets per elevator. Specifically, the double shock-absorbing pad assembly 2 includes an upper base plate 3, an intermediate clamping plate 4, a lower base plate 5, and rubber blocks 6. The intermediate clamping plate 4 is positioned between the upper base plate 3 and the lower base plate 5. The rubber blocks 6 are positioned between the intermediate clamping plate 4 and the upper base plate 3, and between the intermediate clamping plate 4 and the lower base plate 5. Multiple rubber blocks 6 are provided; each set of double shock-absorbing pad assembly 2 has four rubber blocks 6, symmetrically distributed at the four corners of the intermediate clamping plate 4. The rubber blocks 6 are bonded and fixed to the intermediate clamping plate 4, the upper base plate 3, and the lower base plate 5 using adhesive.

[0014] Continue reading Figure 1-2To prevent excessive shear deformation of the rubber block 6 under stress, which could cause the rope wheel to tilt, a limiting hole 7 is provided on the double shock-absorbing pad assembly 2. A limiting bolt 8 is inserted into the limiting hole 7. The limiting bolt 8 passes through the limiting hole 7 and the upper beam of the car frame in sequence to limit the radial displacement of the double shock-absorbing pad assembly.

[0015] During installation, first place the double vibration damping pad assembly 2 on the mounting surface of the car frame upper beam. Then, hoist the sheave seat 1 equipped with the anti-reverse sheave 9 onto it, aligning the mounting holes of the sheave seat 1, the limiting holes 7 of the double vibration damping pad assembly 2, and the mounting holes of the car frame upper beam. Insert the limiting bolts 8 for limiting, and finally, use fastening screws to tighten from both sides to press and fix the entire assembly. After installation, when the elevator is running, the vibration of the wire rope is transmitted to the sheave seat through the anti-reverse sheave and is effectively absorbed and attenuated by the double vibration damping pad assembly installed below it, thereby reducing the vibration and noise transmitted to the car.
