In the present embodiment, the first mounting cylinder 4 is a circular cylinder and is located on the other side of the steel wire rope 1, the opening of the first mounting cylinder 4 being opened at one end close to the steel wire rope 1.

[0021] A blocking rod 3 is slidably disposed within the first mounting tube 4. The blocking rod 3 is a circular rod-shaped structure, and its diameter is smaller than the inner diameter of the first mounting tube 4. The blocking rod 3 is pushed out of the first mounting tube 4 by a first compression spring 6 to trip the hanging chair 2. Specifically, the first compression spring 6 is located in the first cavity, and a blocking ring 301 is fixedly disposed around the outer wall of the blocking rod 3. The inner wall of the blocking ring 301 is fixedly connected to the outer wall of the blocking rod 3. The outer wall of the blocking ring 301 has the same inner diameter as the first mounting tube 4, and the two are clearance-matched, ensuring that the blocking ring 301 can slide along the inner wall of the first mounting tube 4. The first compression spring 6 is sleeved on the blocking rod 3 and is located between the partition plate 403 and the blocking ring 301, that is, one end of the first compression spring 6 is fixedly connected to the blocking ring 301, and the other end of the first compression spring 6 is fixedly connected to the partition plate 403.
[0022] The bottom of the first mounting cylinder 4 is provided with an electromagnet 5 powered by the power supply 10, and the electromagnet 5 will attract the blocking rod 3 into the first mounting cylinder 4 after being powered on, so that the hanging chair 2 can pass through; in the embodiment, the electromagnet 5 is located in the second cavity, and a through hole is formed in the center of the partition plate 403 for the blocking rod 3 to pass through, and the diameter of the through hole is greater than the diameter of the blocking rod 3, so that the blocking rod 3 can smoothly pass through the partition plate 403. The electromagnet 5 is electrically connected with the power supply 10 through the transmission line 1001, and the bottom of the first mounting cylinder 4 is provided with a threading hole 401 for the transmission line 1001 to pass through.
[0023] The power supply 10 powers the electromagnet 5, which is controlled by a switch unit arranged at a safe distance from the boarding position, the switch unit includes a static contact 703 arranged in the second mounting cylinder 7 and a movable contact 704 arranged on the sliding block 8, the second mounting cylinder 7 is fixed on the support of the aerial passenger system, and the second mounting cylinder 7 can be a circular cylindrical structure or a square cylindrical structure, in the embodiment, the second mounting cylinder 7 is a square cylindrical structure with an open end, and the open end of the second mounting cylinder 7 is arranged at the end close to the steel wire rope 1. The bottom of the second mounting cylinder 7 is fixedly connected with a first connecting rod 701, the first connecting rod 701 is perpendicular to the bottom plate of the second mounting cylinder 7, and the first connecting rod 701 is located at the center of the bottom plate, and the connection between the first connecting rod 701 and the second mounting cylinder 7 is welding; the static contact 703 is located at the free end of the first connecting rod 701, and is electrically connected with the power supply 10. The second connecting rod 702 is fixedly connected to the end face of the second mounting cylinder 7, and the second connecting rod 702 is located at the center of the end face, and the connection between the second connecting rod 702 and the sliding block 8 is welding; the movable contact 704 is located at the free end of the second connecting rod 702, and is electrically connected with the power supply 10.
[0024] In the embodiment, the sliding block 8 is slidingly arranged in the second mounting cylinder 7, and one end of the sliding block 8 extending out of the second mounting cylinder 7 has a slope surface on the moving track of the hanging chair 2, as shown in Figure 1 The bottom end of the slope surface is located on the left side, and the top end of the slope surface is located on the right side, and the end face also has a flat surface flush with the top end of the slope surface, so that the hanging chair 2 in the boarding position can pass through smoothly. The sliding block 8 is touched and pressed during the movement of the hanging chair 2, so that the movable contact 704 is in contact with the static contact 703, and then the power supply 10 powers the electromagnet 5. The second mounting cylinder 7 is provided with a second compression spring 9 for separating the static contact 703 and the movable contact 704 to make the electromagnet 5 de-energized, and the number of the second compression spring 9 is two and is symmetrically distributed on both sides of the first connecting rod 701, one end of the second compression spring 9 is fixedly connected with the bottom plate of the second mounting cylinder 7, and the other end of the second compression spring 9 is fixedly connected with the end face of the sliding block 8 extending into the second mounting cylinder 7.
[0025] The working process of this device is as follows: when the previous hanging chair 2 moves to the switch unit, the hanging chair 2 first touches the slope of the slider 8 and squeezes the slider 8 to slide into the second mounting tube 7 until the moving contact 704 contacts the static contact 703. At this time, the second compression spring 9 is compressed, and the power supply 10 supplies power to the electromagnet 5. After the electromagnet 5 is powered, it draws the blocking rod 3 into the first mounting tube 4. At this time, the first compression spring 6 is compressed, and the hanging chair 2 at the boarding position begins to move. After the previous hanging chair 2 passes the slider 8, the second compression spring 9 pushes the slider 8 toward the direction of extending out of the second mounting tube 7, separating the moving contact 704 and the static contact 703, and the electromagnet 5 is de-energized. The blocking rod 3, under the action of the first compression spring 6, extends out of the first mounting tube 4, tripping the next hanging chair 2.
[0026] The above is a basic implementation of the present invention, which can be further improved, optimized and limited to obtain the following embodiments:
[0027] Example 2
[0028] This embodiment is an improvement on the basis of embodiment 1. Its main structure is the same as that of embodiment 1, with the improvement being that a limit ring 402 is provided around the inner side wall of the opening of the first mounting tube 4. The inner diameter of the limit ring 402 is smaller than the outer diameter of the baffle and larger than the diameter of the blocking rod 3. The limit ring 402 is connected to the first mounting tube 4 by welding or bolting. The retaining ring 301 cooperates with the limit ring 402 to limit the maximum extension length of the blocking rod 3. When the first compression spring 6 pushes the blocking rod 3 out of the first mounting tube 4, the retaining ring 301 moves to the limit ring 402 to prevent the blocking rod 3 from extending too long, which would prevent the electromagnet 5 from being able to absorb the blocking rod 3 when energized. That is, the cooperation between the retaining ring 301 and the limit ring 402 limits the maximum extension length of the blocking rod 3, thereby ensuring the normal operation of the device.
[0029] Example 3
[0030] This embodiment is an improvement on the basis of embodiment 1, and its main structure is the same as that of embodiment 1, with the improvement being that a lever 201 is fixedly provided on the hanging chair 2. The lever 201 is a rectangular rod-shaped structure, which is fixed on the hanging rod of the hanging chair 2. When the hanging chair 2 passes through the switch unit, the lever 201 touches the slider 8 and pushes the slider 8 to slide.
