Description

Technical Field

[0001] The utility model relates to the field of box-type elevators, in particular to a shock-absorbing and adjusting device for an elevator load-bearing beam. Background Art

[0002] The interference of elevator vibration and noise is an important factor affecting the comfort of high-rise residents and elevator passengers.

[0003] First, the low-frequency vibration sound energy caused by the driving operation of the traction machine, the operation of the car and the counterweight in the elevator shaft propagates along the main load-bearing walls of the structure, causing resonance in the wall and floor slab vibrations, which causes adverse reactions to residents and elevator users.

[0004] Secondly, the friction of the traction equipment causes the elevator car to move up and down. The friction sound generated between the traction wheel and the traction rope during the operation of the elevator will also be transmitted to the car through the wire rope, and further transmitted to the guide rails and adjacent walls, affecting the life and rest of the residents.

[0005] How to achieve vibration reduction for box-type elevators and realize quiet and smooth operation of the elevators is the main goal of the technicians. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a shock-absorbing adjustment device for an elevator load-bearing beam, which can achieve a shock-absorbing effect for a box-type elevator.

[0007] A technical solution to achieve the above object is: an elevator load-bearing beam damping adjustment device, including a traction system and a guide rail, and also including a rubber damping pad;

[0008] The traction system includes a traction machine, an elevator load-bearing beam and a support seat, and the traction machine is connected to the elevator load-bearing beam;

[0009] The connecting part of the elevator load-bearing beam is provided with a rubber vibration-damping pad, and the elevator load-bearing beam, the rubber vibration-damping pad and the support seat are connected and fixed by a bolt assembly with a hole, and the support seat can be slidably clamped on the guide rail.

[0010] Furthermore, a 1 mm clearance is left between the bolt on the support seat side of the hole bolt assembly and the support seat.

[0011] Furthermore, the bolt assembly with a hole is connected to the elevator load-bearing beam through a nylon sleeve, and the bolt assembly with a hole is installed inside the nylon sleeve.

[0012] Furthermore, the upper part of the nylon sleeve is a guide sleeve, and the longitudinal section of the nylon sleeve is a convex-shaped structure.

[0013] Furthermore, the bolt assembly with a hole is composed of an M16 bolt with a hole, an M16 double nut, a φ16 spring washer, a φ16 double flat washer and a cotter pin.

[0015] The utility model is a shock-absorbing and adjusting device for an elevator load-bearing beam. The traction system is fixed on the guide rail and has no direct contact with the building shaft. The elevator load-bearing beam is fixed on the support seat through a nylon sleeve with a bolt assembly with a hole. A rubber shock-absorbing pad is sandwiched between the load-bearing beam and the support seat to reduce the transmission of mechanical collision and vibration. The shock-absorbing and adjusting device for the elevator load-bearing beam is an elastic vibration reduction device that can weaken the vibration transmission rate by 99%, effectively reduce the propagation of vibration, solve the resonance problem caused by the disturbance of the wall and floor caused by the vibration of the elevator, and make the elevator car run smoothly.

[0020] In order to better understand the technical solution of the utility model, the following is a detailed description through specific embodiments:

[0021] See also Figure 1 The utility model discloses an elevator load-bearing beam shock-absorbing and adjusting device, comprising a traction machine 1, an elevator load-bearing beam 2, a rubber shock-absorbing pad 3, a bolt assembly with a hole 3 and a support seat 6.

[0022] The traction machine 1 is connected to the elevator load-bearing beam 2 and is arranged in the center of the elevator load-bearing beam 2. The connection part of the elevator load-bearing beam 2 is provided with a rubber vibration-damping pad 4. The bolt assembly with holes 3 connects and fixes the elevator load-bearing beam 2, the rubber vibration-damping pad 4 and the support seat 6, and the support seat 6 can be slidably clamped on the guide rail 7. The bolt on the support seat side of the bolt assembly with holes 3 and the support seat leave a matching gap of d=1mm. The bolt assembly with holes is connected to the elevator load-bearing beam through a nylon sleeve 5, and the bolt assembly with holes is installed inside the nylon sleeve. Please refer to Figure 3 and Figure 4 The upper part of the nylon sleeve is the guide sleeve, and the longitudinal section of the nylon sleeve is a convex-shaped structure.

[0023] See also Figure 2The bolt assembly with holes is composed of M16 bolt with holes 8, M16 double nut 10, φ16 spring washer 11, φ16 double flat washer 12, and cotter pin 9. A φ16 spring washer is placed in the middle of the double nut. After a 1mm gap is reserved for fixing the load-bearing beam, the double nut fixes and tightens the middle spring washer to prevent the nut from loosening. A perforated pin is added to prevent the bolt with holes from falling off, avoiding the risk of displacement of the rubber shock-absorbing pad.

[0024] The utility model uses a bolt assembly with a hole to fix the support seat, nylon sleeve, rubber shock-absorbing pad and load-bearing beam together, avoiding the displacement and falling off of the rubber shock-absorbing pad, and ensuring the smooth operation of the elevator main unit. The bolt assembly with a hole is installed in the inner hole of the nylon sleeve, and the nylon sleeve avoids the collision and friction between the bolt with a hole and the load-bearing beam when the rubber shock-absorbing pad rebounds to generate noise. The elevator traction machine is directly above the elevator load-bearing beam, and the force applied by the elevator load-bearing beam to the shock-absorbing adjustment device is even, and the deformation of the shock-absorbing adjustment device assembly is also the same. In this way, during the braking or movement of the elevator traction machine, the vibration is evenly distributed to each rubber shock-absorbing pad, and is absorbed and converted by the lower rubber shock-absorbing pad, which greatly reduces the shaking and low-frequency noise generated by the elevator traction system during operation.

[0025] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
