Problems solved by technology

However, in this technology, a single air spring is used for adjustment, and its adjustment direction and strength depend on the adjustment force of the spring itself, and this adjustment method is imprecise and uncontrollable, and the shock absorption effect is not obvious; another On the one hand, the response of the spring itself is not sensitive enough. It takes a certain time for it to provide the rebound force after receiving the compression force, and it is often impossible to adjust the vibration of the elevator in a timely and accurate manner.

specific Embodiment 1

[0037] Such as figure 1 The shown elevator is provided with a shock absorbing device, including a hoisting device hoist 1 , a guiding device 26 , a sling 2 , a car 3 , a counterweight 21 , and a compensating device 20 . One end of the sling 2 is connected to the car 3 that can move vertically in the elevator shaft 25. After the sling has walked around the hoist and the guide, its other end is connected to the counterweight 21 that can move vertically in the elevator shaft. The car 3 is connected to a counterweight 21 through a compensating device 20 .

[0038] A damping device 13 is arranged between the car bottom 28 and the car bottom frame 27, which can be referred to figure 2 and image 3 , The damping device 13 is respectively provided with one at four corner positions in the space between the car bottom 28 and the car bottom frame 27 . The shock absorbing device 13 includes an upper connecting plate 131 , an outer layer of elastic material 132 , an inner layer of elas...

specific Embodiment 2

[0044] This embodiment adopts a kind of elevator provided with damping device in embodiment 1, and refer to Figure 4 The control flow chart of using the damping device to adjust the balance of the car after the elevator is installed is completed, and the action of the damping device 13 to adjust the balance of the car 3 is 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 sensing device 24 acquires the level status 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 car 3 level state signal. The air valve 1352 and the exhaust valve 1353 charge and exhaust the damping device 13, and adjust the level of the car 3; during this process, the car level sensing device 24 continuously inputs the balance state signal of the car 3 The value control device 17 repeats...

specific Embodiment 3

[0045] This embodiment adopts a kind of elevator provided with damping device in embodiment 1, and refer to Figure 5 Adjust the car bottom leveling and car balance control process flow chart when the elevator is running in the normal running state of the elevator, and describe the actions of the shock absorber 13 to adjust the leveling of the car 3 and the balance control of the car 3 when the elevator is running. During the normal operation of the elevator, passengers are loaded and unloaded by the car 3, and the load capacity 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. The position changes and the car 3 is unbalanced; or when the car 3 loads and unloads passengers, the passenger positions are different, which will also cause the car 3 to be unbalanced. When the elevator loads and unloads passengers, the door opening ...

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...
