Description

Technical Field

[0001] The present invention relates to the technical field of cableways, and in particular to an operating system of a linear motor-driven gondola in a passenger cableway station. Background Art

[0002] Passenger ropeway is a kind of transportation facility for transporting passengers. It has the characteristics of crossing mountains and rivers and overcoming obstacles. It is also a green, low-carbon, energy-saving, emission-reducing, fast and comfortable means of transportation. It is widely used in mountainous areas, scenic spots, ski resorts, urban transportation and other occasions. Passenger ropeway has many types, among which the single-line circulating detachable rope gripper passenger ropeway is more common. It can automatically detach from the carrying rope when the cabin enters the station and run at a low speed in the station, which is convenient for passengers to get on and off safely. Then it will be re-attached to the carrying rope when the cabin leaves the station, and run at high speed on the ropeway line to improve transportation efficiency and safety. Therefore, the key technology of the single-line circulating detachable rope gripper ropeway is the process of detaching and attaching the cabin gripper and the carrying wire rope, driving the cabin to run at different predetermined speeds on the track in the station. This patent is an innovative use of linear motor technology to improve the current driving method of the cabin running in the station.

[0003] Refer to the attached drawings in the specification Figure 1 After the cable car enters the station, its deceleration, uniform speed and acceleration process depends on the close cooperation of rubber power take-off wheels, pulleys, rubber tires, friction plates and other components. Specifically, the power take-off wheel obtains power by friction through close contact with the carrying wire rope, and then transmits the power to the rubber tire through the pulley. The rubber tire then rolls on the friction plate on the cable gripper connected to the suspension rod of the car, and the friction generated between the two drives the car to run at different speeds in the station, thus forming the operation mechanism of the car in the station. However, there are many disadvantages in this traditional operation mode. On the one hand, since the movement of the car in the station is completely achieved by mechanical rotation and contact friction, the mechanical structure of the transmission system is relatively complex, the number of rotating parts is large, the operation efficiency is low, the wearing parts are prone to failure, the reliability is low, and the maintenance work is heavy and complicated. On the other hand, the transmission speed ratio of the traditional transmission system is fixed and the departure interval cannot be changed, which limits the adjustment space of the car operation mode and makes it difficult to flexibly change the operation status according to actual needs.

[0005] The embodiment of the present invention is achieved as follows:

[0006] The embodiment of the present application provides an operation system of a passenger ropeway station in which a linear motor drives a gondola, comprising a steel structure in the station and a gondola travel track. A plurality of linear motor stators are distributed on the steel structure (2) in the station above the gondola travel track (3); a linear motor mover is arranged on the top of the gondola suspension rod; when the linear motor stator is energized, a traveling wave magnetic field is generated, and the linear motor mover cuts the traveling wave magnetic field to generate an induced electromotive force and current, and an electromagnetic force is generated under the interaction of the air gap magnetic field between the linear motor stator and the mover, thereby pushing the gondola forward.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0016] The operation mode and advantages of the cabin transmission system in the passenger ropeway station of the present application are remarkable.

During the slow operation stage in the station, the linear motor drives smoothly to ensure that the cabin moves forward at a uniform speed, still maintaining a contactless and frictionless state, and running quietly and accurately. When the cabin is to accelerate out of the station, the electromagnetic force of the linear motor is increased to drive the cabin to accelerate, and the whole process is smooth and efficient. In addition, thanks to the use of linear motor technology in the system, the speed of the cabin can be adjusted according to operational needs, whether it is to cope with rapid turnover during peak passenger flow or slow operation under special circumstances, it can be easily achieved, greatly improving the flexibility and adaptability of passenger ropeway operations.

[0021] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0022] Example

[0023] Please refer to Figure 1 and Figure 2The embodiment of the present application provides an operation system of a linear motor driven gondola in a passenger ropeway station, comprising a steel structure 2 in the station and a gondola travel track 3, wherein the steel structure 2 in the station supports the gondola travel track 3, and a plurality of linear motor stators 1 are distributed above the track 3; a linear motor mover 5 is arranged at the top of the suspension rod of the gondola 6; when the linear motor stator 1 is energized, a traveling wave magnetic field is generated, and the linear motor mover 5 cuts the traveling wave magnetic field to generate an induced electromotive force and current, and an electromagnetic force is generated under the interaction of the air gap magnetic field between the linear motor stator 1 and the mover 5 to push the gondola 6 forward.

[0024] The operation mode and advantages of the transmission system of the linear motor driven gondola in the passenger ropeway station of the present application are remarkable. When the gondola 6 enters the platform and needs to slow down, the control system regulates the electromagnetic force of the linear motor stator 1, and generates a reverse force on the linear motor mover 5 by changing the magnitude and direction of the electromagnetic force, so as to achieve smooth deceleration of the gondola 6. There is no mechanical contact and no friction during the deceleration process, which avoids component wear and reduces maintenance costs. At the same time, the heat and noise generated by friction are eliminated, and the reliability of the system is improved. In the slow-speed operation stage in the station, the electromagnetic force pushes steadily to ensure that the gondola moves forward at a uniform speed, and still maintains a contactless and frictionless state, and the operation is quiet and precise. When the gondola 6 is to accelerate out of the station, the electromagnetic force thrust is increased to drive the gondola 6 to accelerate, and the whole process is smooth and efficient. In addition, thanks to the use of linear motor technology in the system, the speed of the gondola 6 can be adjusted according to operational needs. Whether it is to cope with rapid turnover during peak passenger flow or slow operation under special circumstances, it can be easily achieved, which greatly improves the flexibility and adaptability of passenger ropeway operation.

[0025] In an embodiment of the present invention, a variable frequency power supply for supplying power to a plurality of the above-mentioned linear motor stators 1 is also included, and any of the above-mentioned linear motor stators 1 is independently connected to the above-mentioned variable frequency power supply.

[0026] It should be noted that: since each linear motor stator 1 can independently obtain power from the variable frequency power supply, when one of the stators fails, it will not affect the normal power supply and operation of other stators, and the reliability of the system can be greatly improved, which can effectively avoid the shutdown of the entire equipment due to local failures and ensure production continuity. Furthermore, independent connection facilitates precise control of the power supply parameters of each stator, and can flexibly adjust the power supply parameters of a single stator according to different working stages and load requirements, optimize motor performance, make equipment operation more efficient, meet diverse operational requirements, and reduce energy consumption and operation and maintenance costs.

[0027] In an embodiment of the present invention, the variable frequency power supply is connected to a control module for independent control of a plurality of the linear motor stators 1 .

[0028] It should be noted that the operator does not need to be present on site, but can remotely and accurately adjust the power supply parameters of each linear motor stator 1 in the control room according to the real-time operating status of the passenger ropeway car 6. Whether it is precise deceleration when the car 6 enters the station, slow and smooth operation in the station, or rapid acceleration when leaving the station, it can be quickly achieved through instructions, which greatly improves the convenience and timeliness of operation.

[0029] In an embodiment of the present invention, the control module realizes speed regulation of the linear motor by changing the frequency of the power supply;

[0030] The control module controls the power supply frequency of the linear motor stator 1 corresponding to the entry and exit sides of the hanging car 6 and the operation in the station, so as to realize the deceleration of the hanging car 6 when entering the station and the acceleration when leaving the station, as well as the uniform speed operation in the station.

[0031] In an embodiment of the present invention, the suspension rod of the above-mentioned hanging car 6 includes a cable gripper and a running wheel 4, the cable gripper is used to cooperate with the carrying rope of the cableway, and the running wheel 4 is used to roll with the above-mentioned hanging car running track 3.

[0032] It should be noted that the rope gripper ensures that the gondola 6 is firmly connected to the carrying rope, and can reliably bear the weight of the entire gondola 6 and passengers when the ropeway is in operation. The running wheels 4 roll with the gondola running track 3, making the gondola 6 smoother during the movement of the station, reducing friction and energy consumption, while allowing the gondola 6 to move smoothly along the predetermined track, ensuring the accurate running direction, improving the overall riding experience, and playing an important role in the smooth, efficient and safe operation of the ropeway system.

[0033] In an embodiment of the present invention, any of the above-mentioned linear motor stators 1 can be detachably matched with the above-mentioned in-station steel structure 2.

[0034] It should be noted that when the linear motor stator 1 fails and needs to be repaired or replaced, the detachable design allows the staff to quickly remove it from the steel structure 2 in the station. The operation is convenient and efficient, which greatly shortens the maintenance time and reduces the impact on the operation of the entire system.

[0035] In an embodiment of the present invention, any of the above-mentioned linear motor stators 1 is connected to the above-mentioned in-station steel structure 2 by bolts, and the position can be easily adjusted.

[0036] It should be noted that when the linear motor stator 1 needs to be maintained, replaced, or the steel structure 2 in the station needs to be adjusted, the bolt connection is easy to operate and can be quickly disassembled without special tools. This not only saves maintenance time and reduces the impact on operations, but also improves the flexibility and maintainability of the equipment, effectively controlling operating costs and failure risks.

[0037] In an embodiment of the present invention, the above-mentioned car travel track 3 may be provided with a branch track, and the car 6 is driven by a linear motor to travel on different paths and enter different areas in the station.

[0038] It should be noted that the branch road provides more running path options for the passenger ropeway cabin 6, and can flexibly divert the cabin 6 to different platforms, maintenance areas, etc., optimize the operation process, and improve transportation efficiency. The departure time is adjusted in real time according to the passenger flow, and the departure is flexible and effective to avoid empty cabins leaving the station.
