DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model

[0026] Embodiment one

[0027] Please refer to Figures 1-7As shown, the embodiment provides an anti-reverse device for an aerial passenger conveying device, which comprises a main shell 1, a support seat 3 mounted on the back of the main shell 1, a shaft 201 rotatably mounted in the main shell 1, a winding wheel 2 fixedly mounted on the top of the shaft 201, an anti-reverse ratchet wheel 202 fixedly mounted on the lower outer wall of the shaft 201, a sliding seat 403 slidably mounted on one side of the inner wall of the main shell 1 through a sliding groove 103, a pawl 401 movably mounted on one side of the sliding seat 403 through a fixed seat 4 and used in cooperation with the anti-reverse ratchet wheel 202, a support spring 402 fixedly mounted on the front side of the fixed seat 4 and connected with the pawl 401, a brake disc 203 fixedly mounted on the upper outer wall of the shaft 201, a brake seat 5 fixedly mounted on one side of the inner wall of the main shell 1 above the brake disc 203 and sleeved on the outer wall of the brake disc 203, brake pistons 502 fixedly mounted on the top and bottom of the brake seat 5, brake pads 501 fixedly mounted in the brake seat 5 and extending from the output ends of the brake pistons 502, a brake oil cylinder 6 fixedly mounted on the rear side of the sliding groove 103, a drive rod 602 fixedly mounted on the output end of the brake oil cylinder 6 and connected with the back of the fixed seat 4, and oil pipes 601 fixedly mounted on the top of the brake oil cylinder 6 and connected with the brake pistons 502.

[0028] In use, the main shell 1 is mounted on the driving end of the aerial passenger conveying device, the winding wheel 2 mounted on the top of the shaft 201 can be connected with the steel rope of the passenger conveying device, so that when the aerial passenger conveying device is running, the winding wheel 2 and the shaft 201 can be driven to rotate, and the shaft 201 can drive the anti-reverse ratchet wheel 202 and the brake disc 203 mounted on the outer wall to rotate. The pawl 401 movably mounted on one side of the fixed seat 4 can contact the anti-reverse ratchet wheel 202, and the support spring 402 can elastically support the pawl 401. When the anti-reverse ratchet wheel 202 rotates in the forward direction, the pawl 401 will not interfere with it, and when the anti-reverse ratchet wheel 202 reverses, the pawl 401 can lock and position it, thereby avoiding the reverse rotation of the anti-reverse ratchet wheel 202, the shaft 201 and the winding wheel 2, thereby preventing the aerial passenger conveying device from reversing. When the pawl 401 supports the anti-reverse ratchet wheel 202 against reverse rotation, the fixed seat 4 and the sliding seat 403 are pushed backward. When the fixed seat 4 moves backward, the drive rod 602 is pushed. The pushing of the drive rod 602 can inject the hydraulic oil in the brake oil cylinder 6 into the brake pistons 502 through the oil pipes 601. The brake pistons 502 can push the brake pads 501 to move. When the brake pads 501 move, the brake disc 203 mounted on the outer wall of the shaft 201 can be locked and positioned, thereby achieving the function of secondary anti-reverse treatment of the shaft 201 and the winding wheel 2, reducing the pressure of the anti-reverse ratchet wheel 202 and the pawl 401 against the aerial passenger conveying device against reverse rotation, and improving the stability of the device against reverse rotation of the aerial passenger conveying device.

The two sets of limiting wheels 302 installed on the front surfaces of the support plates 301 can limit the steel ropes entering and exiting the winding wheel 2. By limiting the steel ropes when entering and exiting, the steel ropes can be wound multiple turns around the outer wall of the winding wheel 2, avoiding the situation that the multiple turns of the steel ropes touch each other and cause friction when wound around the outside of the winding wheel 2. By winding the steel ropes multiple turns, the contact area and friction with the winding wheel 2 are increased, avoiding the situation that the steel ropes slip when the overhead passenger device is prevented from reversing, and increasing the stability of the device when the overhead passenger device is prevented from reversing.
