Description

Technical Field

[0001] The present application relates to the technical field of high-speed elevators, and in particular to a high-speed elevator capable of controlling the vibration frequency of a steel wire rope. Background Art

[0002] The natural frequency of a compensating wire rope is related to its length, linear density, and tension. High-speed elevators often use fixed-weight compensating tensioners, whose primary function is to tighten the compensating wire rope to limit its sway. Some ultra-high-speed elevators are equipped with damped compensating tensioners, which provide both tension and vertical damping, slowing the vertical speed of the compensating tensioner. However, the tensioning force of such damped compensating tensioners remains fixed. Therefore, when the linear density and tension of the compensating wire rope are determined, the frequency of the compensating wire rope is only related to its length.

[0003] When a high-speed elevator is in operation, the length of the compensating rope changes, and the frequency changes accordingly. Assuming the natural frequency of the compensating rope varies within the range [a, b], when the building is short, the building's sway frequency f is lower than the natural frequency range of the compensating rope, meaning f < [a, b]. However, when the building exceeds a certain height (for example, over 400 meters), the building's sway frequency falls within the natural frequency range of the compensating rope, meaning f is within the interval [a, b]. At this point, when the high-speed elevator reaches a certain height, the natural frequency of the compensating rope approaches the building's sway frequency, causing the compensating rope and the building to resonate, affecting ride comfort and even the safety of the high-speed elevator.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application discloses a high-speed elevator capable of controlling the vibration frequency of a steel wire rope. Figure 1 and Figure 2, including a traction machine 1, a car 2, a counterweight frame 3, a compensating wire rope 4, a hydraulic control system 5 and an elevator control system 6. The traction machine 1 is located in the elevator machine room, one end of the wire rope on the traction machine 1 is connected to the top of the car 2, and the other end is connected to the top of the counterweight frame 3; the hydraulic control system 5 is located below the car 2, one end of the compensating wire rope 4 is connected to the bottom of the car 2, and the other end acts on the bottom of the counterweight frame 3, and the compensating wire rope 4 is controlled by the hydraulic control system 5; the hydraulic control system 5 is electrically connected to the elevator control system 6, and the elevator control system 6 is used to adjust the output pressure of the hydraulic control system 5.

[0033] The elevator control system 6 is used to collect signals and transmit them to the hydraulic control system 5. The hydraulic control system 5 adjusts the output pressure on the compensating wire rope 4 to change the tensioning force of the compensating wire rope 4, thereby changing the natural frequency of the compensating wire rope 4, so that the natural frequency of the compensating wire rope 4 is always greater than the swing frequency of the building, thereby solving the problem of resonance between the compensating wire rope 4 and the building and improving the riding comfort and operation safety of the high-speed elevator.

[0034] A first rope end 21 is mounted at the lower end of the car 2, and a second rope end 31 is mounted on the side wall of the counterweight frame 3. The ends of the compensating wire rope 4 are secured to the first and second rope ends 21, 31, respectively. The elevator control system 6 includes a control cabinet 61, a seismic detector 62, a vibration sensor 63, a second cable 64, and a traveling cable 65. Both the control cabinet 61 and the seismic detector 62 are located in the elevator machine room. The seismic detector 62 is electrically connected to the control cabinet 61 via the second cable 64. When an earthquake or strong wind causes the building to sway, the seismic detector 62 can detect the building's sway frequency and transmit it to the control cabinet 61 via the second cable 64. A vibration sensor 63 is mounted on the first rope end 21 and electrically connected to the control cabinet 61 via the traveling cable 65. When the compensating wire rope 4 vibrates, the vibration sensor 63 detects the vibration frequency of the compensating wire rope 4 and transmits it to the control cabinet 61 via the traveling cable 65.

[0035] A first cable 7 is provided between the elevator control system 6 and the hydraulic control system 5. The hydraulic control system 5 includes a compensating tensioner 51 and a control device 52. The control device 52 is mounted on the compensating tensioner 51, around which the compensating wire rope 4 is wound. The control device 52 is used to adjust the output pressure of the compensating tensioner 51 to change the tension of the compensating wire rope 4. The control device 52 is electrically connected to the control cabinet 61 via the first cable 7. When the control device 52 receives a command from the control cabinet 61, it adjusts the output pressure of the control device 52 to change the tension of the compensating wire rope 4, thereby changing the natural frequency of the compensating wire rope 4.

[0036] Reference Figure 2 and Figure 3 The compensation tensioning device 51 includes an upper beam 511, a column 512, a base 513, a suspended counterweight 514 and a damping device 515. The column 512 is vertically arranged, the upper beam 511 is fixedly connected to the upper end of the column 512, the base 513 is fixedly connected to the lower end of the column 512, and the base 513 is fixed to the ground; the suspended counterweight 514 is sleeved on the column 512, and the compensation wire rope 4 is wound around the suspended counterweight 514; the column 512 is close to the two ends of the suspended counterweight 514. Guide rails 516 are provided on each side of the column 512, extending along the length of the column 512. Two guide shoes 517 are mounted on the two inner walls of the column 512, along the vertical axis. These two guide shoes 517 are simultaneously slidably mounted within the same guide rail 516, allowing the levitation counterweight 514 to slide up and down within the guide rail 516 of the column 512. The compensating wire rope 4 moves synchronously with the levitation counterweight 514, thereby varying the tension of the compensating wire rope 4. One end of the damping device 515 is bolted to the lower end of the upper beam 511, and the other end is mounted on the levitation counterweight 514. Two damping devices 515 are provided, symmetrically located on either side of the column 512. These damping devices 515 act as buffers, slowing the speed at which the levitation counterweight 514 slides up and down within the guide rail 516.

[0037] The control device 52 includes a hydraulic workstation 521, a booster oil pipe 522, and a booster oil cylinder 524. One end of the booster oil pipe 522 is connected to the hydraulic workstation 521, and the other end of the booster oil pipe 522 is connected to the booster oil cylinder 524. The hydraulic workstation 521 is electrically connected to the control cabinet 61 via a first cable 7. The upper end of the booster oil cylinder 524 is fixedly connected to the upper beam 511, and the lower end of the booster oil cylinder 524 is fixedly connected to the suspended counterweight 514. The booster oil cylinder 524 can drive the suspended counterweight 514 to slide up and down within the guide rail 516.

[0038] When the hydraulic workstation 521 receives an instruction from the control cabinet 61, the hydraulic workstation 521 controls the boosting oil pipe 522 to load or unload the hydraulic oil in the boosting cylinder 524, so that the boosting cylinder 524 enters or exits the working state. The boosting cylinder 524 drives the suspended counterweight 514 to slide up and down in the guide rail 516 to change the tension of the compensation wire rope 4, thereby changing the natural frequency of the compensation wire rope 4.

[0039] Reference Figure 2 and Figure 4The booster cylinder 524 includes an inner cylinder 5241 and an outer cylinder 5242. The outer cylinder 5242 is sleeved around the inner cylinder 5241 and can slide relative to each other. The upper end of the inner cylinder 5241 is fixedly connected to the upper beam 511, and the lower end of the outer cylinder 5242 is fixedly connected to the suspended counterweight 514. When the outer cylinder 5242 moves up and down, it can drive the suspended counterweight 514 to slide up and down on the guide rail 516. A flow hole 5245 is opened at the center of the bottom of the inner cylinder 5241 for the flow of hydraulic oil. The upper end of the inner cylinder 5241 has a connecting port, in which an oil pipe joint 5243 is installed. The oil pipe joint 5243 is connected to the booster oil pipe 522 for loading or unloading the hydraulic oil in the inner cylinder 5241.

[0040] When the control device 52 is not working, the tensioning force of the compensation wire rope 4 is equal to the tension of the compensation wire rope 4 caused by the deadweight of the suspended counterweight 514. When the control device 52 is working, if it is necessary to increase the natural frequency of the compensation wire rope 4, the hydraulic workstation 521 loads hydraulic oil into the inner cylinder 5241 through the boosting oil pipe 522, and the outer cylinder 5242 presses the suspended counterweight 514 downward, thereby increasing the tensioning force of the compensation wire rope 4. If it is necessary to reduce the natural frequency of the compensation wire rope 4, the hydraulic oil in the inner cylinder 5241 flows back to the hydraulic workstation 521 along the boosting oil pipe 522, the pressure in the boosting oil cylinder 524 decreases, and the compensation wire rope 4 pulls the suspended counterweight 514 upward, thereby driving the outer cylinder 5242 upward until the oil pressure in the boosting oil cylinder 524 returns to the gauge pressure (which can be regarded as atmospheric pressure), that is, the tensioning force of the compensation wire rope 4 is reduced to the tension of the deadweight of the suspended counterweight 514 on the compensation wire rope 4.

[0041] A pressure relief port is provided at the bottom of outer cylinder 5242, which houses a pressure relief valve 5244. Pressure relief pipe 523 is attached to relief valve 5244, which is connected to hydraulic workstation 521 to relieve pressure from booster cylinder 524. If the high-speed elevator experiences an emergency, such as an emergency stop, while control device 52 is in operation, the pressure in booster cylinder 524 could exceed the allowable value. In this case, pressure relief valve 5244 activates, causing hydraulic oil to flow back through relief pipe 523 to hydraulic workstation 521, which then stops loading hydraulic oil into booster cylinder 524, protecting the safety of the high-speed elevator.

[0042] The implementation principle of a high-speed elevator capable of controlling the vibration frequency of a steel wire rope disclosed in an embodiment of the present application is as follows: an earthquake detector 62 is installed in the elevator machine room, and the earthquake detector 62 can detect the swaying frequency of the building and transmit it to the control cabinet 61 through a second cable 64; a vibration sensor 63 is installed on the first rope head 21, and the vibration sensor 63 is used to detect the vibration frequency of the compensation steel wire rope 4 and transmit it to the control cabinet 61 through a traveling cable 65; the control cabinet 61 transmits the signals detected by the earthquake detector 62 and the vibration detector to the hydraulic workstation 521 through the first cable 7, and the hydraulic workstation 521 controls the boosting oil pipe 522 to load or unload the hydraulic oil in the boosting cylinder 524 to change the force of the boosting oil cylinder 524 on the suspended counterweight 514, change the tension of the compensation steel wire rope 4, and thus change the natural frequency of the compensation steel wire rope 4, so that the natural frequency of the compensation steel wire rope 4 is always greater than the swaying frequency of the building, thereby solving the problem of resonance between the compensation steel wire rope 4 and the building and improving the riding comfort and operation safety of the high-speed elevator.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
