Description

Technical Field

[0001] This utility model relates to the field of aerial passenger transport technology, and in particular to an anti-reverse protection device for aerial passenger transport. Background Technology

[0002] Mining overhead personnel carriers (also known as "monkey cars") are crucial equipment for transporting personnel underground in mines, and their operational safety directly impacts miners' lives. In actual operation, due to design flaws, missing critical protection functions, or inadequate management and maintenance, "reverse runaway" phenomena can easily occur—that is, the wire rope suddenly reverses direction, causing passengers to be thrown out due to inertia, resulting in serious accidents. Common design flaws include the lack of effective anti-reverse protection, the absence of speed reducers with backstop functions, and the lack of real-time monitoring of wire rope status and emergency braking mechanisms. Although relevant national standards have mandatory requirements for some protective devices, many critical protection functions (such as wire rope anti-reverse, rope breakage capture, and three-stage braking) are not fully covered or are not properly implemented in practice.

[0003] Therefore, it is necessary to provide a new anti-reverse protection device for aerial passenger transport to solve the above-mentioned technical problems. Summary of the Invention

[0004] The technical problem solved by this utility model is to provide an anti-reverse protection device for aerial passenger transport that can significantly enhance the real-time performance and safety of anti-reverse protection without affecting the operation of the main system.

[0005] To solve the above-mentioned technical problems, the anti-reverse protection device for aerial passenger transport provided by this utility model includes: a first support frame, a rope-supporting wheel rotatably mounted on one side of the first support frame, a connecting rod fixedly mounted on the side of the rope-supporting wheel away from the first support frame, a turntable mounted on the side of the connecting rod away from the rope-supporting wheel, a support rod fixedly mounted on the turntable, an iron block fixedly mounted on the support rod, an mounting plate fixedly mounted on the side of the first support frame away from the rope-supporting wheel, one end of an L-shaped rod fixedly mounted on the side of the mounting plate close to the first support frame, a stop post fixedly mounted on the other end of the L-shaped rod, the stop post contacting the support rod, and an infrared sensor provided on the side of the iron block away from the support rod.

[0006] Preferably, a second support frame is fixedly installed on the outside of the infrared sensor, and the top of the second support frame and the first support frame are fixedly installed on the same third support frame.

[0007] Preferably, the top of the rope-supporting pulley is provided with a steel wire rope.

[0008] Preferably, the turntable has an installation groove, the connecting rod is rotatably installed in the installation groove, and an insulating seat is fixedly installed on the inner wall of the installation groove and at one end of the connecting rod located in the installation groove. At least one magnetic block is fixedly installed on the side of the two insulating seats that are close to each other.

[0009] Preferably, the magnetic poles of the magnetic blocks on the two insulating bases that are close to each other are opposite.

[0010] Compared with related technologies, the anti-reverse protection device for aerial passenger transport provided by this utility model has the following beneficial effects: This utility model provides an anti-reverse protection device for an aerial passenger transport device. Through direct contact between the rope pulley and the wire rope, in the event of a reverse rotation, it immediately drives the mechanical transmission components (connecting rod, turntable, support rod, and iron block) to move, triggering the infrared sensor. This achieves a millisecond-level signal response and promptly sends an emergency stop signal to the control panel, effectively preventing further reverse rotation. The device incorporates a magnetic block structure that works in conjunction with a stop post to further confirm the displacement status during mechanical movement. Combined with infrared non-contact detection, it avoids malfunctions or failures caused by environmental factors such as oil or humidity, improving the accuracy of signal judgment. The infrared sensor signal is connected in series with the normally closed emergency stop node on the control panel. Once a reverse rotation signal is detected, the control circuit is immediately cut off, forcing a stop, which meets the functional requirements for emergency stop protection in the "Coal Mine Safety Regulations" and eliminates potential delays caused by human intervention.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the anti-reverse rotation protection device for an aerial passenger transport device provided by this utility model; Figure 2 for Figure 1 The diagram shows a top view of the connection structure of the turntable, support rod, iron block, L-shaped rod, stop post, second support frame and infrared sensor. Figure 3 A cross-sectional view of the connection structure between the turntable and the connecting rod in one embodiment of the anti-reverse protection device for the aerial passenger transport device provided by this utility model. Figure 4 for Figure 3 The diagram shows a side view of the installation structure of the magnetic block and insulating base. The anti-reverse protection device for the overhead passenger transport device includes: a first support frame 1, a rope-supporting wheel 2 rotatably mounted on one side of the first support frame 1, a connecting rod 3 fixedly mounted on the side of the rope-supporting wheel 2 away from the first support frame 1, a turntable 4 mounted on the side of the connecting rod 3 away from the rope-supporting wheel 2, a support rod 5 fixedly mounted on the turntable 4, an iron block 6 fixedly mounted on the support rod 5, an installation plate 7 fixedly mounted on the side of the first support frame 1 away from the rope-supporting wheel 2, one end of an L-shaped rod 8 fixedly mounted on the side of the installation plate 7 close to the first support frame 1, a stop post 9 fixedly mounted on the other end of the L-shaped rod 8, the stop post 9 contacting the support rod 5, and an infrared sensor 11 provided on the side of the iron block 6 away from the support rod 5.

[0015] A second support frame 10 is fixedly installed on the outside of the infrared sensor 11, and the same third support frame 12 is fixedly installed on the top of the second support frame 10 and the first support frame 1.

[0016] The top of the rope pulley 2 is provided with a steel wire rope 13.

[0017] In this embodiment, the turntable 4 is provided with an installation groove 14, the connecting rod 3 is rotatably installed in the installation groove 14, and an insulating seat 15 is fixedly installed on the inner wall of the installation groove 14 and at one end of the connecting rod 3 located in the installation groove 14. At least one magnetic block 16 is fixedly installed on the side of the two insulating seats 15 that are close to each other.

[0018] The magnetic poles of the magnetic blocks 16 on the two insulating seats 15 that are close to each other are opposite.

[0019] In this embodiment, by setting the connecting rod 3 and the turntable 4 to be rotatably connected, and cooperating with the magnetic block 16 on the insulating seat 15, when the wire rope 13 reverses, the connecting rod 3 can be driven to rotate by the rope pulley 2, and the magnetic block 16 on the connecting rod 3 can be driven to rotate by the magnetic block 16 on the turntable 4, thereby realizing that the turntable 4 rotates together with the connecting rod 3. When the support rod 5 contacts the stop post 9, the turntable 4 stops rotating with the connecting rod 3.

[0020] In other embodiments, the connecting rod 3 and the turntable 4 can also be rotated. Under normal circumstances, the support rod 5 is in contact with the stop post 9, causing the rope-supporting wheel 2 to rotate with the wire rope 13. Only when the wire rope 13 reverses will the rope-supporting wheel 2 rotate. And when the support rod 5 is in contact with the other side of the stop post 9, the rope-supporting wheel stops rotating.

[0021] The working principle of the anti-reverse protection device for the aerial passenger transport system provided by this utility model is as follows: When the overhead passenger transport device reverses, the wire rope 13 moves in the opposite direction. At this time, the wire rope 13 drives the support wheel 2 to rotate. The support wheel 2 drives the iron block 6 to move through the connecting rod 3, turntable 4 and support rod 5, so that the iron block 6 rotates around the connecting rod 3 as the axis, thereby causing the support rod 5 to rotate from one side of the stop column 9 to the other side. At this time, the iron block 6 is facing the infrared sensor 11, thereby triggering the infrared sensor 11. The infrared sensor is connected in series with the normally closed emergency stop node of the operating panel of the overhead passenger transport device. When the infrared sensor 11 is triggered, the emergency stop switch of the operating panel is opened and the equipment stops operating.

[0022] Compared with related technologies, the anti-reverse protection device for aerial passenger transport provided by this utility model has the following beneficial effects: This utility model provides an anti-reverse protection device for an aerial passenger transport device. The device uses a rope pulley 2 in direct contact with the wire rope 13. In the event of a reverse rotation, it immediately drives the mechanical transmission components (connecting rod 3, turntable 4, support rod 5, and iron block 6) to move, triggering the infrared sensor 11. This provides a millisecond-level signal response and promptly sends an emergency stop signal to the control panel, effectively preventing further reverse rotation. The device incorporates a magnetic block 6 structure that works in conjunction with the stop column 9 to further confirm the displacement status during mechanical movement. Combined with infrared non-contact detection, this avoids malfunctions or failures caused by environmental factors such as oil or humidity, improving the accuracy of signal judgment. The signal from the infrared sensor 11 is connected in series with the normally closed emergency stop node on the control panel. Once a reverse rotation signal is detected, the control circuit is immediately cut off, forcing a stop. This meets the functional requirements for emergency stop protection in the "Coal Mine Safety Regulations," eliminating potential delays caused by human intervention.
