Technical Field

[0001] This utility model relates to the field of elevator vibration reduction technology, specifically to a shock-absorbing structure for a double beam and rubber of an elevator traction machine. Background Technology

[0002] During the operation of the traction machine, the low-frequency vibration sound energy it generates will be transmitted through the main load-bearing wall of the structure, causing the wall and floor slab to resonate and conduct vibration and noise into the residents' rooms. The residents on the top and second-to-top floors are most significantly affected, which seriously interferes with their normal daily life, reduces their living experience, and causes a large number of complaints and conflicts.

[0003] Currently, the industry mainly uses the method of directly laying ordinary vibration-damping rubber pads or installing spring shock absorbers at the bottom of the elevator traction machine for vibration control. During installation, the traction machine is installed on the base, which is fixed to the beam. The beam is installed through holes drilled in the wall. To reduce vibration transmission, vibration-damping rubber is usually installed between the base and the beam. However, installing rubber between the beam and the wall requires secondary construction of the wall, increasing the complexity and cost of construction. On the other hand, some customers refuse to carry out wall construction due to concerns about damage to the wall structure or the impact of decoration, making it difficult to implement the double vibration reduction solution, thus increasing the difficulty of construction. Utility Model Content

[0006] The dual vibration damping assembly includes vibration damping rubber installed between the auxiliary beam and the traction machine beam. Steel plates for connecting with the auxiliary beam and the elevator guide rail clamp are fixed on both sides of the vibration damping rubber. Long holes are provided on the steel plates.

[0007] Preferably, the steel plates located on opposite sides of the anti-vibration rubber are bonded to the steel plates by vulcanization, and two parallel steel bars are welded to the outer side of the steel plates for connection with the traction machine beam.

[0008] Preferably, multiple stiffening plates are installed at equal intervals on the auxiliary beam, a channel steel is installed at one end of the auxiliary beam, and an angle steel for mounting with the base assembly is installed at the other end of the auxiliary beam.

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a shock-absorbing structure of a double beam and rubber for an elevator traction machine, including an auxiliary beam 1 installed on the traction machine beam 9, wherein a base assembly 2 for installing the traction machine and a double vibration damping assembly for damping the vibration of the traction machine are installed on the auxiliary beam 1, and the double vibration damping assembly is located below the base assembly 2.

[0025] The dual vibration damping assembly includes a vibration damping rubber 3 installed between the auxiliary beam 1 and the traction machine beam 9. The vibration damping rubber 3 has steel plates 4 fixed on both sides for connecting with the auxiliary beam 1 and the elevator guide rail clamp 5. The steel plates 4 have elongated holes 10, which are arranged along the direction of the steel plates 4, and are 2-4 in number and symmetrically distributed. The two steel plates 4 and the vibration damping rubber 3 form a steel plate 4-rubber-steel plate 4 composite structure, which allows the vibration damping rubber 3 to be replaced individually, reducing maintenance costs.

[0026] By adding an auxiliary beam 1 above the existing traction machine beam 9, and installing anti-vibration rubber 3 between the auxiliary beam 1 and the existing traction machine beam 9, a steel plate 4 is fixed to the outside of the anti-vibration rubber 3 at the bottom of the auxiliary beam 1. The steel plate 4 has elongated holes 10. The auxiliary beam 1 is fixed to the existing traction machine beam 9 by passing a guide rail clamp through the elongated holes 10. The fixing position can be flexibly adjusted according to the width of the existing traction machine beam 9 using the cooperation of the elongated holes 10 and the guide rail clamp, adapting to beams of different specifications. A base assembly 2 is installed above the auxiliary beam 1. The original anti-vibration rubber 3 is retained between the base assembly 2 and the auxiliary beam 1, forming a dual vibration reduction path of base-auxiliary beam 1-existing beam, achieving efficient vibration reduction without modifying the beam and wall, thus improving the engineering adaptability of the solution.

[0027] The steel plates 4 located on opposite sides of the anti-vibration rubber 3 are bonded to the steel plate 4 by vulcanization. Two parallel steel bars 11 are welded to the outer side of the steel plate 4 for connection with the traction machine beam 9. The steel bars 11 are welded perpendicularly to the upper steel plate 4, and the length of the steel bars 11 is not less than the length of the welding area. During the welding operation, the steel bars 11 can block the conduction of high temperature and prevent the anti-vibration rubber 3 from deteriorating due to heat.

[0028] Multiple stiffening plates 101 are installed at equal intervals on the auxiliary beam 1. A channel steel 12 is installed at one end of the auxiliary beam 1, and an angle steel 13 for installation with the base assembly 2 is installed at the other end of the auxiliary beam 1. One of the steel plates 4 on the anti-vibration rubber 3 is installed on the auxiliary beam 1 or the channel steel 12. There is no need to chisel or modify the wall, reducing construction steps, shortening the installation cycle, and reducing the impact on the customer's daily life.

[0029] A stud 14 passes through the elongated hole 10, and nuts 15 are threaded to both ends of the stud 14. Both the auxiliary beam 1 and the elevator guide rail clamp 5 are provided with through holes for the threads to pass through. By passing the stud 14 through the through holes and the elongated hole 10, and then restricting the two ends of the stud 14 with nuts 15, the elevator guide rail clamp 5 and the steel plate 4, as well as the auxiliary beam 1 and the steel plate 4, are detachable. This makes installation convenient, adaptable to existing beams of different widths, and has a wide range of applications.

[0030] Multiple buffer rubbers 6 are installed between the base assembly 2 and the auxiliary beam 1. The multiple buffer rubbers 6 are located at the four corners of the bottom of the base assembly 2. Through the double-layer rubber combination of vibration damping rubber 3 and buffer rubber 6, double vibration reduction is achieved without altering the wall structure, effectively attenuating low and medium frequency vibrations. The noise reduction effect is significantly better than that of a single vibration reduction structure.

[0031] It also includes multiple rubber A7s installed on the traction machine beam 9 and the machine room floor. The multiple rubber A7s are located at both ends of the traction machine beam 9. The traction machine beam 9 and the machine room floor are provided with mounting holes for connecting the rubber A7s. When the customer agrees to the construction of the beam and the wall, the rubber A7s between the beam and the wall adopt a special design.

[0032] Gaskets 8 are vulcanized and bonded to both ends of the rubber A7. The two gaskets 8 on the rubber A7 are fixed to the machine room floor and the traction machine beam 9, respectively. The rubber A7, the buffer rubber 6 and the vibration damping rubber 3 are all made of nitrile rubber or neoprene rubber. The composite structure composed of gaskets 8, rubber A7 and gaskets 8 allows the composite mechanism to be selected and installed according to actual usage requirements.

[0033] The strategy of installing vibration-damping rubber at the contact points between the traction machine beam and the wall, or between the beam and the traction machine base, allows for flexible selection of installation locations to precisely block the vibration propagation path. Depending on the actual construction conditions, when modifications to the shaft wall are limited, rubber can be added directly to the beam to achieve site-specific vibration reduction and noise reduction, effectively minimizing the impact on top-floor and second-to-top-floor residents. Vibration-damping rubber can be flexibly installed at the contact points between the traction machine beam and the wall, or between the beam and the traction machine base, depending on the convenience of on-site construction, forming a targeted vibration buffer barrier. This flexible design ensures vibration reduction effectiveness while avoiding unnecessary structural modifications, significantly improving the engineering adaptability of the solution and providing a completely new approach to elevator vibration reduction.

[0034] When the shaft wall structure is difficult to modify, vibration damping rubber can be added directly to the traction machine beam; if the wall modification conditions permit, it is preferable to install it at the contact position between the beam and the wall. This on-site installation method reduces construction difficulty and cost, expands the scope of application of the vibration damping solution, and meets the needs of diverse engineering scenarios.

[0035] By utilizing the elastic deformation and damping properties of vibration-damping rubber, the propagation path of low-frequency vibrations is cut off at the connection between beams and walls or beams and bases. Regardless of the installation location, vibration energy can be dissipated in the form of heat energy, effectively suppressing wall and floor resonance, significantly reducing the transmission of vibration and noise to residents' homes, and fundamentally solving the problem of elevator operation disturbing residents.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
