Description

Technical Field

[0001] This application relates to the field of elevator technology, specifically to a shock absorption device and traction system for a heavy-duty elevator. Background Technology

[0002] In traditional elevator designs, the large weight they bear results in significant vibrations and impacts during operation. To reduce the transmission of vibrations to the building structure and lower noise levels, shock-absorbing rubber and other elastic components are typically installed in the elevator's support structures. However, this design has significant technical drawbacks in elevator applications.

[0003] First, elevators have a much higher load than ordinary passenger elevators, especially when frequently transporting heavy goods. Under long-term high loads, the shock-absorbing rubber is prone to excessive compression or plastic deformation, which can lead to the failure of the shock-absorbing device. It can even cause the installation position of the elevator traction machine to shift, thus affecting the alignment of the traction sheave and the wire rope, resulting in uneven distribution of traction force. In severe cases, it may even cause problems such as wire rope slippage, unstable car operation, or abnormal wear of the guide rails, ultimately leading to elevator malfunction and affecting safety and service life. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a shock absorption device for heavy-duty elevators, and the technical solution adopted includes:

[0005] A shock absorption device for a heavy-duty elevator includes a main frame mounted on a load-bearing beam. The upper end of the main frame is provided with a main mounting plate, a first shock-absorbing rubber pad, a clamping plate, and a second shock-absorbing rubber pad arranged sequentially from top to bottom. The upper end of the main mounting plate is used to mount a traction machine. Fasteners pass through the main mounting plate and are threadedly connected to the clamping plate, or the fasteners pass through the clamping plate and are threadedly connected to the main mounting plate. The fasteners can be tightened or loosened under external force to adjust the distance between their lower ends and the main frame.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the host mounting plate is provided with a first through hole, the clamping plate is provided with a second through hole, the clamping plate is provided with a first nut above the second through hole and a second nut below the second through hole, and the fastener is inserted into the first through hole, the first nut, the second through hole and the second nut in sequence to make the fastener threadedly connected to the clamping plate.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the fastener is a bolt.

[0008] This application also discloses a traction system, including a traction machine and the above-mentioned heavy-duty elevator shock absorption device, characterized in that the traction machine is mounted on the main unit mounting plate.

[0009] The beneficial effects of this utility model are:

[0010] Under light loading conditions, there is a gap between the fastener and the main frame. The shock absorption device dampens the main body of the traction machine and controls the vibration amplitude of the main body within a set range.

[0011] Under heavy load conditions, after the first or second damping rubber pad is compressed under the load, the fasteners abut against the main frame. The first or second damping rubber pad will not be over-compressed under the load, avoiding excessive deformation of the damping rubber under heavy load, which would cause the damping device to fail. The first and second damping rubber pads still effectively absorb and dampen the vibration generated by the traction machine, ensuring the smooth operation of the elevator and improving the comfort of operation.

[0019] Reference Figure 1-2 This application proposes an embodiment of the traction system, which includes a shock-absorbing device and a traction machine 20. The shock-absorbing device includes a main frame 30 mounted on a load-bearing beam 10. The upper end of the main frame 30 is provided with a main mounting plate 40, a first shock-absorbing rubber pad 50, a clamping plate 60, and a second shock-absorbing rubber pad 70 arranged sequentially from top to bottom. The traction machine 20 is mounted on the upper end of the main mounting plate 40. Fasteners 80 are provided on both sides of the main frame 30. The fasteners 80 pass through the main mounting plate 40 and are threadedly connected to the clamping plate 60, or the fasteners 80 pass through the clamping plate 60 and are threadedly connected to the main mounting plate 40. The fasteners 80 can be tightened or loosened under external force to adjust the distance between their lower ends and the main frame 30.

[0020] The fastener 80 can be tightened or loosened under external force to adjust the compression degree of the first shock-absorbing rubber pad 50 or the second shock-absorbing rubber pad 70.

[0021] When the traction system is under light load conditions, the shock absorption device reduces the vibration of the main unit of the traction machine 20 and controls the vibration amplitude of the main unit within a set range.

[0022] When the traction system is under heavy load, the first damping rubber pad 50 or the second damping rubber pad 70 is compressed under the load, and the fastener 80 abuts against the main frame 30. The first damping rubber pad 50 or the second damping rubber pad 70 will not be over-compressed under the load, avoiding excessive deformation of the damping rubber under heavy load, which would cause the damping device to fail. The first damping rubber pad 50 and the second damping rubber pad 70 still effectively absorb and dampen the vibration generated by the traction machine 20, ensuring the smooth operation of the elevator and improving the comfort of operation.

[0023] Specifically, in this embodiment, when the freight elevator operates within the loading range of 0 to 50% of its rated load, the fastener 80 is adjusted so that there is a gap between the lower end of the fastener 80 and the main frame 30. The shock absorption device absorbs the vibration of the main unit and controls its amplitude to a set value. When the freight elevator operates between 50% and 100% of its rated load, the fastener 80 will press the main frame 30 tightly. The compression of the shock-absorbing rubber pad will not decrease, and the shock-absorbing rubber pad can still absorb the vibration generated by the traction machine 20, improving the comfort of operation and meeting the loading requirements.

[0024] Referring to the accompanying drawings, the fastener 80 is a bolt. The main mounting plate 40 has a first through hole, and the clamping plate 60 has a second through hole. The clamping plate 60 has a first nut 90 above the second through hole and a second nut 100 below the second through hole. The fastener 80 is inserted sequentially into the first through hole, the first nut 90, the second through hole, and the second nut 100 to make the fastener 80 threadedly connected to the clamping plate 60. The first nut 90 and the second nut 100 ensure that the fastener 80 can be effectively threadedly connected to the clamping plate 60, and can also distribute and transmit the pressure and torque in the equipment or structure, ensuring the normal operation of the equipment when subjected to large loads.

[0025] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
