DETAILED DESCRIPTION

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1-5As shown, this embodiment proposes an anti-reversal structure of an aerial passenger device, including a backstop 1 and an electromagnetic trigger rope clamp 2. The backstop 1 is installed on the low-speed shaft end 301 of the reducer 3 of the driving part of the aerial passenger device. The electromagnetic trigger rope clamp 2 is installed on the driving part of the aerial passenger device, and two groups of electromagnetic trigger rope clamps 2 are installed. One end of the traction wire rope 4 of the aerial passenger device is inserted into the two groups of electromagnetic trigger rope clamps 2 and then led out. The backstop 1 includes an outer ring 101, an inner ring 102 and a special-shaped eccentric wedge 103. The inner ring 102 is installed on the reducer 3 of the driving part of the aerial passenger device. A keyway 104 is provided on the inner wall of the inner ring 102 on the outer wall of the low-speed shaft end 301. The keyway 104 of the inner ring 102 transmits torque after being connected with the key of the low-speed shaft end 301 of the reducer 3. An outer ring 101 is provided on the outer side of the inner ring 102. The outer ring 101 is connected to the mounting base of the reducer 3 of the driving part of the overhead passenger device through a check arm 5. A raceway 6 is formed between the outer ring 101 and the inner ring 102. A retaining frame 7 is provided inside the raceway 6. The retaining frame 7 is connected to the inner ring 102. A special-shaped eccentric wedge block 103 is rotatably provided on the retaining frame 7. The special-shaped eccentric wedge blocks 103 are provided in a plurality of groups in a ring array.

[0022] When the inner ring 102 of the backstop 1 rotates in the forward direction, it drives the special-shaped eccentric wedge 103 to rotate together. When the rotation speed is within a certain range, the special-shaped eccentric wedge 103 deflects under the action of centrifugal force and loses contact with the outer ring 101 and the inner ring 102, thereby achieving wear-free operation; when the inner ring 102 rotates in the reverse direction, the special-shaped eccentric wedge 103 contacts with the outer ring 101 and the inner ring 102 under the action of the torsion spring 9, and weds them into one, thereby bearing the reverse torque transmitted by the inner ring 102.

[0023] The retaining frame 7 includes an upper ring plate 701, a lower ring plate 702 and an intermediate plate 703. The upper ring plate 701 is provided above the inside of the raceway 6, the lower ring plate 702 is provided below the upper ring plate 701, and the intermediate plate 703 is provided between the upper ring plate 701 and the lower ring plate 702. The intermediate plates 703 are provided in multiple groups.

[0024] A rotating shaft 8 is provided between adjacent intermediate plates 703 , and the upper and lower ends of the rotating shaft 8 are rotatably connected to the bottom of the upper ring plate 701 and the top of the lower ring plate 702 respectively. The special-shaped eccentric wedge block 103 is installed on the rotating shaft 8 .

[0025] The upper end of the rotating shaft 8 extends out of the top of the upper ring plate 701 , and a torsion spring 9 is connected between the upper end of the rotating shaft 8 and the upper ring plate 701 . The torsion spring 9 provides an initial contact force between the special-shaped eccentric wedge block 103 and the inner ring 102 and the outer ring 101 .

[0026] The check arm 5 is provided with a through slot, the outer ring 101 is located in the through slot, the check arm 5 is provided with a fixing bolt 10, the fixing bolt 10 is provided in multiple groups, and one end of the fixing bolt 10 is connected to the outer wall of the outer ring 101. The check arm 5 is provided with a pin hole, and an anti-rotation pin 11 is provided in the pin hole. The check arm 5 is connected to the mounting base on the reducer 3 of the driving part of the overhead passenger device through the anti-rotation pin 11. By installing the outer ring 101 using the check arm 5 and the anti-rotation pin 11, the outer ring 101 can be fixed to prevent the outer ring 101 from rotating, and the check arm 5 and the backstop can be disassembled and installed by providing the fixing bolt 10.

[0027] The electromagnetically triggered rope clamp 2 is connected to the speed limiter 13 of the overhead passenger device through the brake wire 12. When the driving wheel and the detour wheel lining are greasy or severely worn, resulting in reduced friction, and the passengers gather on the same side, the traction wire rope 4 is likely to slip. The electromagnetically triggered rope clamp 2 can quickly and effectively prevent this from happening.

[0028] The utility model installs a backstop 1 at the low-speed shaft end 301 of the reducer 3 of the driving part of the overhead passenger device. During the startup process of the overhead passenger device, the high and low speed end brakes are opened and the inner ring 102 of the backstop 1 rotates in the reverse direction when the motor is not started. Under the action of the torsion spring 9, the special-shaped eccentric wedge block 103 contacts the inner ring 102 and the outer ring 101 and weds them into one, so as to withstand the reverse torque transferred by the inner ring 102, so that the backstop 1 is still in a braking state, thereby avoiding the occurrence of equipment reversal phenomenon; by arranging the electromagnetic trigger rope clamp 2, the traction wire rope 4 can be quickly clamped after the rope slips and overspeeds, so as to implement braking.

[0029] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
