Example Embodiment

Specific embodiment 1:

[0037] like figure 1 The shown elevator provided with a shock absorption device includes a hoisting device hoist 1 , a guide device 26 , a sling 2 , a car 3 , a counterweight 21 , and a compensation device 20 . One end of the sling 2 is connected to the car 3 that can move vertically in the elevator hoistway 25 , and the other end of the sling is connected to the counterweight 21 that can move vertically in the elevator hoistway after the sling bypasses the hoist and the guide device. The car 3 is connected to a counterweight 21 via a compensation device 20 .

[0038] A shock absorbing device 13 is provided between the car bottom 28 and the car bottom frame 27 , please refer to figure 2 and image 3 , the damping device 13 is provided at each of the four corner positions in the space between the car bottom 28 and the car bottom frame 27 . The damping device 13 includes an upper connecting plate 131 , an outer layer 132 of elastic material, an inner...

Example Embodiment

Specific embodiment 2:

[0044] This embodiment adopts the elevator provided with the shock absorbing device in the first embodiment, and refers to Figure 4 The control flow chart of using the damping device to adjust the balance of the car after the installation of the elevator is completed, and the action of the damping device 13 to adjust the balance of the car 3 will be described. After the elevator is installed, the car 3 is located at the leveling position of the base station with no load, and is in an unloaded state. The car level sensor device 24 acquires a level state signal of the car 3 and inputs the signal to the control device 17 . The control device 17 determines the balanced state of the car 3 according to the input signal of the horizontal state of the car 3. When it is determined that the car 3 is in an unbalanced state, the control device 17 controls the gas supply device 19 and controls the air flow in the damping device 13. The air valve 1352 and the exha...

Example Embodiment

Specific embodiment 3:

[0045] This embodiment adopts the elevator provided with the shock absorbing device in the first embodiment, and refers to Figure 5 The process flow chart of adjusting the car bottom leveling and the car balance control when the elevator is running in the normal running state of the elevator is described in the following figure. During the normal operation of the elevator, passengers are loaded and unloaded by the car 3, and the load in the car 3 is different, which causes the height of the shock absorbing device 13 with adjustable height to change, causing the height of the car bottom 28 to change accordingly, resulting in leveling. If the position changes and the car 3 is in an unbalanced state; or when the car 3 loads and unloads passengers, the passengers stand in different ways, which will also cause the car 3 to be unbalanced. When the elevator is loading and unloading passengers, the door opening and closing detection device 4 located on the ca...

Abstract

The invention discloses a vibration reduction elevator. The vibration reduction elevator comprises a lifting device, an elevator car and vibration reduction devices, wherein the lifting device is fixedly connected with the elevator car, and the vibration reduction devices are arranged between a car platform and a car platform frame of the elevator car; each vibration reduction device comprises an upper connecting plate, an elastic material layer, a pressure sensing device, a lower connecting plate and air chambers, wherein the elastic material layer is arranged between the upper connecting plate and the lower connecting plate and fixedly connected with the upper connecting plate and the lower connecting plate to form a closed air chamber, air inlet valves and exhaust valves are arranged on the lower connecting plate, and the pressure sensing device is arranged on the lower connecting plate. According to the vibration reduction elevator, the vertical flexibility is high, the rigidity and the vertical height can be adjusted, the self-vibration frequency of the elevator car can be decreased, inflating and deflating work can be conducted according to the elevator car loading and unloading weight, vibration and noise transmitted to the elevator car can be effectively absorbed, and the elevator taking comfortableness can be improved.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices, in particular to a shock absorbing elevator and a control method thereof. Background technique [0002] Elevators are the main means of transportation for vertical transportation in buildings. During the operation of the elevator, the comfort of the passengers in the car has always been the focus of attention. Passengers' discomfort when riding an elevator is mainly caused by the vibration generated by the unbalanced load of the car and the vibration generated by the elevator running to the car. In addition, during the operation of the elevator, the insufficient installation accuracy of the elevator guide rails will also cause the vibration generated by the elevator operation; moreover, the vibration generated by the building will also be transmitted to the elevator car, which also reduces the comfort of passengers when taking the elevator. [0003] In the prior art, the commonl...
