[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, high, low, top, bottom" generally refer to the position of the corresponding component or structure in the direction of gravity. Figure 1 The directions of the drawings shown. "Inside and outside" refer to the inside and outside of the corresponding component outline. In addition, it should be noted that the terms used, such as "first, second", etc., are to distinguish one element from another and have no order or importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0020] For ease of understanding, please refer to the attached Figure 1 Detailed description of the structure and working principle of the anti-reverse device of the overhead passenger device disclosed in the present invention in combination with the embodiments.

[0021] The present disclosure relates to an anti-reverse device for an aerial passenger device, which can promptly prevent the aerial passenger device from continuing to reverse after it reverses, thereby ensuring the safety of the staff on the aerial passenger device. Figure 1 and Figure 2 The anti-reverse device for an aerial passenger device disclosed in the present invention comprises a top plate 1, a rotating wheel 2 and a stopper 3. The top plate 1 serves as the installation base of the anti-reverse device for an aerial passenger device. The rotating wheel 2 and the stopper 3 are both located on the top plate 1. The top plate 1 can be made of metal material, such as a steel plate, so as to ensure the strength of the top plate 1 and prevent it from being damaged under the impact of the aerial passenger device. The rotating wheel 2 is rotatably connected to the top plate 1, and the rope of the aerial passenger device can be carried by the rotating wheel 2 to ensure the normal operation of the aerial passenger device.

[0022] The stopper 3 is rotatably connected to the top plate 1, and includes a stop position and a passing position. The stopper 3 can switch between the stop position and the passing position by rotating relative to the top plate 1. When the overhead passenger device passes through the stopper 3 normally, the overhead passenger device can push the stopper 3 to rotate forward, from the stop position to the passing position, to ensure that the overhead passenger device can pass normally, and after the overhead passenger device passes, under the action of its own gravity, it rotates back from the passing position to the stop position, to ensure the subsequent anti-retrograde effect. When the overhead passenger device fails and reverses and reverses to the stopper 3, the stopper 3 is in the stopper position and will not rotate under the action of the overhead passenger device, so that the overhead passenger device can be prevented from continuing to reverse in time, ensuring the safety of the staff located thereon.

[0023] The anti-reverse device for the aerial passenger device disclosed in the present invention is provided with a stopper 3 rotatably connected to the top plate 1, so as to ensure that the aerial passenger device can be prevented from continuing to reverse after the aerial passenger device reverses under normal operation conditions by the stopper 3, thereby ensuring the safety of the staff. Moreover, since it is a purely mechanical structure, it is not easy to fail, and it also has a long service life and good stability.

[0024] In one embodiment of the present disclosure, see Figure 1 and Figure 2 , the stop plate 31 is rotatably connected to the top plate 1 through a hinge. A matching portion is provided on the side of the stop plate 31 close to the top plate 1, and a matching portion is also provided on the bottom surface of the top plate 1. The stop plate 31 and the matching portion on the top plate 1 can be matched together, and then the rotating shaft is inserted into the two matching portions to rotatably connect the stop plate 31 and the top plate 1 together through a hinge connection. The stop plate 31 is rotatably connected to the top plate 1 through a hinge connection. Since the hinge part is usually made of metal, it has high strength and hardness, can withstand a large weight, and is not easy to break, so that the stop plate 31 and the top plate 1 can have good stability. On the other hand, the structure of the hinge connection is relatively simple, and it is also easy to install and maintain the stop plate 31 and the top plate 1, and it is also easy to disassemble and replace. Of course, in other embodiments, the stop plate 31 and the top plate 1 can also be rotatably connected together through other rotatable connection methods known to those skilled in the art, which will not be repeated here.

[0025] In one embodiment of the present disclosure, see Figure 1 and Figure 2 A limit member 313 is provided on the stop plate 31. The limit member 313 can prevent the stop plate 31 from being separated from the hinge structure, thereby ensuring the stability of the connection between the stop plate 31 and the top plate 1. Figure 1In this embodiment, the stopper 313 includes a nut disposed on the stopper plate 31 and a bolt located in the nut. The end of the bolt passes through the nut and extends to the position of the hinge shaft. The bolt can prevent the shaft from axially moving out of the hinge structure, thereby ensuring that the stopper plate 31 will not be separated from the top plate 1. Of course, in other embodiments, the stopper 313 can also be of other structures, as long as the stability of the stopper plate 31 on the top plate 1 can be ensured, and the present disclosure does not limit this.

[0026] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The stopper 3 includes a stopper plate 31 and a blocking member 32. The stopper plate 31 is rotatably connected to the top plate 1. The stopper plate 31 can be in a flat plate shape, which is convenient for connection and installation and has a good blocking effect. The blocking member 32 is fixedly connected to the top plate 1. By setting the blocking member 32, the rotation direction of the stopper plate 31 can be limited when the stopper plate 31 is in the stop position, so that the stopper plate 31 can only rotate in the direction of the passing position, thereby being able to timely block the overhead passenger device when the overhead passenger device goes in reverse. See Figure 1 In this embodiment, the blocking member 32 may be a triangular iron disposed on the top plate, so as to contact the stop plate 31 and block the rotation of the stop plate 31. Of course, in other embodiments, the stop member 3 may also be of other structures, which may be determined according to actual conditions, such as the type of the overhead passenger device, and the present disclosure does not limit this.

[0027] In one embodiment of the present disclosure, see Figure 1 and Figure 2 A counterweight 311 is provided on the stop plate 31. By providing the counterweight 311, after the aerial passenger device passes through the stop plate 31, the stop plate 31 can be quickly rotated from the passing position to the stopping position under the action of the counterweight 311, thereby accelerating the conversion of the stop plate 31 between the two positions. Figure 1 In this embodiment, the counterweight 311 is a rectangular iron block disposed on the stop plate 31. The weight of the rectangular iron block can drive the stop plate 31 to quickly rotate from the passing position to the stopping position, ensuring that the stop plate 31 can be in the stopping position when the aerial passenger device is reversed, thereby increasing the safety and stability of the aerial passenger device anti-reverse device disclosed in the present invention. Of course, in other embodiments, the counterweight 311 can also be of other structures, which can be determined according to actual conditions, as long as it can drive the stop plate 31 to rotate quickly, and the present invention does not limit this.

[0028] In one embodiment of the present disclosure, see Figure 1 and Figure 2A rope groove 312 is provided on the stop plate 31. The rope groove 312 allows the rope of the overhead passenger device to pass through the stop plate 31 without hindering the stop plate 31 from pressing against the blocking member 32. Since the rope of the overhead passenger device is always located in the stop member 3, if the rope groove 312 is not provided for the rope to pass through, the stop plate 31 will rest on the rope and cannot completely press against the blocking member 32. When the overhead passenger device goes in reverse, the rope will hinder the stop plate 31 from pressing against the blocking member 32 to a certain extent, reducing the stability of the stop plate 31, weakening the stopping effect of the stop plate 31, and increasing safety hazards. Figure 1 The rope groove 312 is a semicircular hole arranged at the bottom of the stop plate 31 and passing through the bottom of the stop plate 31. The rope of the overhead passenger device can be located in the rope groove 312 and move in the rope groove 312 without hindering the movement of the stop plate 31 and pressing against the blocking member 32.

[0029] In one embodiment of the present disclosure, see Figure 1 and Figure 2 , an anti-collision layer 314 is provided on the side of the stop plate 31 facing the blocking member 32. The anti-collision layer 314 can reduce the impact force of the stop plate 31 on the blocking member 32 when the stop plate 31 rotates from the passing position to the stopping position and when the overhead passenger device reverses, thereby preventing the stop plate 31 or the blocking member 32 from being damaged during the collision and increasing the safety risk. The anti-collision layer 314 can be made of a flexible material and covered on the surface of the stop plate 31, for example, it can be made of resin or rubber, etc. The specific material and structure of the anti-collision layer 314 can be determined according to actual conditions, for example, according to the magnitude of the force when the stop plate 31 and the blocking member 32 collide, and the present disclosure does not limit this.

[0030] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The top plate 1 is provided with a mounting hole 11 and a mounting member 12, through which the top plate 1 can be fixedly connected to the mounting position of the overhead passenger device. Figure 1 In this embodiment, the mounting hole 11 is a threaded hole, and the mounting member 12 is a bolt. When the top plate 1 is fixedly connected, the bolt can be passed through the threaded hole and rotated to complete the fixed connection of the top plate 1. Of course, in other embodiments, the mounting hole 11 and the mounting member 12 can also be other structures, as long as the top plate 1 can be fixedly connected to the installation position, which can be determined according to actual conditions, and the present disclosure does not limit this.

[0031] When the anti-reverse device of the overhead passenger device disclosed in the present invention is used, it is first necessary to install the top plate 1 to the installation position of the overhead passenger device through the cooperation between the installation hole 11 and the installation member 12. After that, the overhead passenger device starts to operate normally. When the manned device in the moving process passes through the stop plate 31 in the forward direction, it can push the stop plate 31 to rotate from the stop position to the passing position and pass through the stop plate 31 smoothly. After the manned device passes, the stop plate 31 will be driven by the counterweight 311 and quickly rotated from the passing position back to the stop position to ensure the subsequent stopping effect. When the manned device reverses due to a malfunction of the overhead passenger device, after the manned device passes through the stop plate 31, the blocking member 32 will block the movement of the stop plate 31, and the stop plate 31 will prevent the manned device from continuing to reverse, thereby preventing accidents and ensuring the safety of the staff on the manned device.

[0032] The anti-reverse device of the aerial passenger device disclosed in the present invention is provided with a stopper 3 rotatably connected to the top plate 1. Under the premise that the aerial passenger device can smoothly pass the stopper 3 during normal operation, when the aerial passenger device reverses, the stopper 3 can prevent the aerial passenger device from continuing to reverse, thereby ensuring the safety of the personnel on the aerial passenger device and avoiding accidents.

[0033] According to the second aspect of the present disclosure, there is also provided an overhead passenger device, comprising a plurality of the overhead passenger device anti-retrograde devices and ropes described in the above embodiments, wherein the plurality of overhead passenger device anti-retrograde devices are evenly arranged along the extension direction of the rope, and the overhead passenger device anti-retrograde devices are provided in both the upward and downward directions of the overhead passenger device. By providing a plurality of overhead passenger device anti-retrograde devices, a better anti-retrograde effect can be ensured, and even after one of the overhead passenger device anti-retrograde devices fails, the other devices can also play an anti-retrograde effect, thereby further improving the safety of the overhead passenger device. The specific installation and working process of the overhead passenger device anti-retrograde device can refer to the description in the above embodiments, and will not be elaborated on here.

[0034] In one embodiment of the present disclosure, the interval between the anti-reverse devices of the adjacent overhead passenger devices is not greater than 200m. If the interval between the anti-reverse devices of the adjacent overhead passenger devices is large, the overhead passenger device will contact the anti-reverse device of the overhead passenger device only after it has reversed for a large distance, reducing the stopping effect of the stopper 3. In addition, if one of the anti-reverse devices of the overhead passenger device is damaged, the distance between the anti-reverse devices of the adjacent other overhead passenger device is far, which will also reduce the stopping effect of the stopper 3, causing harm to the staff on the overhead passenger device.

[0035] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0037] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
