[0026] Example

[0027] like Figure 1 and Figure 2 As shown, this embodiment discloses a zero-height starting multi-raft common rail magnetic levitation slideway, which is a circular closed slideway. Along the conveying direction of the rafts, the slideway includes a starting belt conveyor 100, a magnetic acceleration device, a starting control unit and a plurality of manned rafts 400. This slideway can accommodate multiple manned rafts 400 to operate therein.

[0028] The magnetic acceleration device includes a conveyor body 210 and a plurality of linear motors 220. The conveyor body 210 is provided with a housing chamber 211 for placing the plurality of linear motors 220. The housing chamber 211 is arranged in the central part of the conveyor body 210. The linear motors 220 are placed in the housing chamber 211 in sequence from head to tail. The head of the linear motor 220 is provided with a first position sensor 221, and the tail is provided with a second position sensor 222. The conveyor body 210 includes a conveying lower section, a conveying section and a conveying higher section. The conveying lower section is connected to one end of the departure belt conveyor 100, and the conveying lower section is arranged at the same height as the departure belt conveyor 100.

[0029] In order to prevent water from entering the linear motor 220 , the first position sensor 221 and the second position sensor 222 , a non-metallic protective cover is fixedly connected to the top of the accommodating cavity 211 , and the non-metallic protective cover blocks the accommodating cavity 211 .

[0030] The start control unit is electrically connected to the linear motor 220, the first position sensor 221 and the second position sensor 222. Specifically, the start control unit includes an input module, a controller and an output module, the input module is connected to the first connection end of the controller, the output module is connected to the second connection end of the controller, the input module includes an input end connected to the first position sensor and the second position sensor, and the output module includes an output end connected to the first position sensor and the second position sensor.

[0031] The controller can be an integrated circuit chip with signal processing capabilities. The above-mentioned controller can be a general controller, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal controller (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components. The methods, steps and logic block diagrams disclosed in the embodiments of the present invention can be implemented or executed. The general controller can be a microcontroller or the controller can also be any conventional controller, etc.

[0032] A plurality of manned rafts 400 are placed on the slide at intervals, and a reaction plate is provided at the bottom thereof. Specifically, the upper layer of the reaction plate is an iron plate and the lower layer is an aluminum plate. When the linear motor 220 is powered on, the linear motor 220 is coupled with the reaction plate, thereby driving the reaction plate to move.

[0033] The slide also includes a descending slide 500 and a speed reducing belt conveyor 600. The attached figure of the present embodiment only shows a partial view of the descending slide. The descending slide 500 includes a descending high section, a descending section and a descending low section. The descending high section is connected to the conveying high section, and the descending low section is connected to the other end of the departure belt conveyor 100 through the speed reducing belt conveyor 600. In addition, the descending low section, the belt speed reducer and the departure belt conveyor 100 are arranged at the same height. The descending slide 500 of the present embodiment can be set in shape according to the actual operating conditions, so the descending slide 500 can be set to a fully enclosed type or a semi-enclosed type. The descending slide 500 in the present embodiment is a fully enclosed type.

[0034] The slide in this embodiment is a closed slide, while the raft 400 of the traditional slide can only slide from a high place to a low place in one direction, which is referred to as an open-loop structure. The raft 400 is then sent back to the starting point by manual or mechanical transportation, and the starting and ending ends of the slide platform are respectively at the starting and ending ends of the steel platform. There is no intermediate process for recovering the raft 400, which reduces the process of workers or machines transporting the raft 400 and increases the frequency of starting.

[0035] A steel platform 800 is provided at the bottom of the slideway. Since the conveying body 210 is used to transport the raft 400 from a low place to a high place, the steel platform has a lower height and a lower construction cost than a traditional steel platform. The steel platform 800 uses significantly less steel. At the same time, the steel platform is less susceptible to natural disasters such as wind and earthquake than a traditional steel platform.

[0036] Stairs 700 for passengers to go up and down are arranged on both sides of the departure belt conveyor 100, which is convenient for passengers to take.

[0037] like Figure 3 As shown, the control method of the zero-height starting multi-skin raft common rail magnetic levitation slide includes the following steps:

[0038] The first position information of the tail of the first raft and the second position information of the head of the second raft are obtained, and whether the distance between the tail of the first raft and the head of the second raft is less than the preset safety distance value is analyzed based on the first position information and the second position information. If the distance between the tail of the first raft and the head of the second raft is less than the preset safety distance value, the linear motor corresponding to the position of the second raft is stopped. When the distance between the tail of the first raft and the head of the second raft is not less than the preset safety distance value, the linear motor corresponding to the position of the second raft is restarted. Based on the first position information of the tail of the first raft and the second position information of the head of the second raft, it is analyzed whether the position information of the above two is less than the preset safety distance value. If it is less than the safety distance value, the second raft is stopped. If it is greater than or equal to the safety distance value, the second raft is restarted, thereby ensuring the smooth operation of the two adjacent rafts, avoiding the safety hazard caused by the adjacent rafts being too close due to mistakes, and ensuring the personal safety of passengers.

[0039] Furthermore, it also includes analyzing whether the first position sensor of the current linear motor head detects whether there is a raft at the corresponding position. If the first position sensor of the current linear motor head does not detect the raft, the current linear motor is stopped. By real-time monitoring of the first position sensor, it can be detected whether the raft at the corresponding position of the conveyor body is in place. If it is in place, the current motor is started to drive the raft to move in the conveying direction. In this way, a large amount of power consumption of the entire equipment can be saved.

[0040] In summary, the closed slide of the present invention uses a multi-raft common rail method to transport passengers to the starting point of the slide, which has high transportation efficiency, and uses a linear motor and a reaction plate coupling method to transport the rafts, which is efficient and fast. By starting the control unit to intelligently control the conveying body, the distance between the rafts and the power consumption of the conveying device can be safely controlled.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
