Description

Technical Field

[0001] The utility model relates to the technical field of elevator balancing and compensating chains, in particular to a balancing and compensating chain guide device with a noise reduction structure. Background Art

[0002] In an elevator, the counterweight and the car move toward each other under the drive of the traction wire rope. When the car is raised, the counterweight moves downward, and when the car is lowered, the counterweight moves upward. In a high-speed elevator, in order to make the car run more smoothly, a balancing and compensating chain is also provided between the car and the counterweight. In the prior art, an elevator system is also provided with an elevator balancing and compensating chain guide device for guiding the elevator balancing and compensating chain. The elevator balancing and compensating chain guide device includes a roller device rolling with the balancing and compensating chain and a mounting bracket.

[0003] The patent specification with the announcement number CN205990129U discloses an elevator balance compensation chain guide device, which includes a balance compensation chain and a counterweight side guide device, one end of the balance compensation chain is fixed to the bottom of the counterweight frame, and the other end is fixed to the bottom of the car frame, the counterweight side guide device is fixed below the counterweight frame, and the elevator balance compensation guide device also includes a car side guide device. It guides and limits the two sides of the balance compensation chain respectively through the car side guide device and the counterweight side guide device, effectively reducing the swing amplitude of the balance compensation chain when the car is running at high speed, making the operation of the balance compensation chain more stable and safer.

[0004] However, in the implementation of relevant technologies, it was found that the elevator balancing compensation chain guide device of the above-mentioned design has the following problems: in the above-mentioned technical solution, a car side guide device is added on the car side on the basis of the existing technology, so that together with the counterweight side guide device, the two sides of the balancing compensation chain are guided respectively to prevent the balancing compensation chain from swinging too much when the car runs at high speed. However, when guiding, multiple sticks are used for guiding, and noise is easily generated when the balancing compensation chain moves and contacts with the sticks. In view of this, a balancing compensation chain guide device with a noise reduction structure is provided to overcome the above-mentioned defects. Utility Model Content

[0022] Reference Figure 1-Figure 4The utility model provides a balancing compensation chain guide device with a noise reduction structure: it includes a fixed frame 1, two connecting members 2 are fixed in the horizontal direction on the right side of the fixed frame 1, the inner sides of the two connecting members 2 are connected to guide members 3, a compensation chain limiting cavity 4 is opened inside the guide member 3, a fixing plate 5 is fixed to the inner wall of the guide member 3, a plurality of sound absorbing holes 6 are opened on the inner surface of the fixing plate 5, four groups of mounting grooves 7 are symmetrically opened inside the guide member 3, and the inner walls of the four groups of mounting grooves 7 are all inlaid with fixed bearings 12. When the balancing compensation chain moves and generates noise, the sound absorbing holes 6 can absorb certain noise through the fixing plate 5 arranged in the guide member 3, thereby achieving the effect of noise reduction and improving practicality.

[0023] As a further implementation scheme of the above technical scheme: the inner wall of the fixed bearing 12 is connected with a connecting rod 8, and the outer surface of the connecting rod 8 is fixed with a guide roller 9. Through the fixed bearing 12 arranged in the mounting groove 7, the connecting rod 8 can be rotated, thereby driving the guide roller 9 to rotate, thereby ensuring the smoothness of the balance compensation chain during movement.

[0024] As a further implementation scheme of the above technical scheme: the outer surface of the guide roller 9 is sleeved with a rubber inner ring 10, and the outer surface of the rubber inner ring 10 is fixed with a wear-resistant outer ring 11. The rubber inner ring 10 arranged between the guide roller 9 and the wear-resistant outer ring 11 can play a certain noise reduction role, thereby avoiding the direct contact between the balancing compensation chain and the guide roller 9 during movement and generating noise.

[0025] As a further implementation scheme of the above technical scheme: limit grooves 13 are provided in the horizontal direction inside the two connecting members 2, and the connecting rod 8 is rotatably connected to the mounting groove 7 through a fixed bearing 12. With the cooperation of the limit grooves 13, the guide member 3 can be pulled in the horizontal direction, thereby adjusting the horizontal position of the guide member 3.

[0026] In specific implementation, before using the balancing compensation chain guide device with a noise reduction structure, the fixed frame 1 is first placed in a suitable position. When the balancing compensation chain moves in the vertical direction, the connecting rod 8 can be rotated through the fixed bearing 12 arranged in the mounting groove 7, and the balancing compensation chain movement and the wear-resistant outer ring 11 generate friction, thereby driving the guide roller 9 to rotate, ensuring the smoothness of the balancing compensation chain movement, and the rubber inner ring 10 arranged between the guide roller 9 and the wear-resistant outer ring 11 can play a certain noise reduction role to avoid the balancing compensation chain directly contacting the guide roller 9 when moving and generating noise, and through the fixed plate 5 arranged in the guide member 3, when the balancing compensation chain moves and generates noise, the sound-absorbing holes 6 arranged can absorb a certain noise, thereby achieving the effect of noise reduction and improving practicality.

[0027] As a further implementation scheme of the above technical scheme: the internal sliding connection of the limit groove 13 is provided with a limit bar 14 fixedly connected to the guide member 3. The limit bar 14 arranged on the guide member 3 can play an adjustment role so that the guide member 3 and the balance compensation chain are in the same vertical line.

[0028] As a further implementation scheme of the above technical scheme: limiting bolts 15 are installed on the upper surfaces of the two connecting parts 2, and the ends of the limiting bolts 15 are abutted and connected with the upper surface of the limiting strip 14. By tightening the limiting bolts 15, the ends of the limiting bolts 15 are in contact with the limiting strip 14, thereby fixing the guide member 3 and reducing the possibility of deviation.

[0029] As a further implementation scheme of the above technical scheme: four fixing bolts 16 are symmetrically installed inside the fixing frame 1, and the fixing frame 1 is fixed by tightening the fixing bolts 16, thereby ensuring the stability of the device.

[0030] During specific implementation, the fixing frame 1 is fixed by tightening the fixing bolts 16 to ensure the stability of the device, and the balancing compensation chain that needs to be guided is passed through the compensation chain limiting cavity 4 inside the guide member 3. When the horizontal position of the device needs to be adjusted, the limiting bolt 15 on the connecting member 2 can be unscrewed so that the end of the limiting bolt 15 is separated from the upper surface of the limiting strip 14, and the fixation of the limiting strip 14 is released. With the cooperation of the limiting groove 13, the guide member 3 can be pulled in the horizontal direction to adjust the horizontal position of the guide member 3 so that the guide member 3 and the balancing compensation chain are on the same vertical line. After the adjustment is completed, the limiting bolt 15 is tightened so that the end of the limiting bolt 15 is in contact with the limiting strip 14, thereby fixing the guide member 3 and reducing the occurrence of deviation.
