Description

Technical Field

[0001] This utility model relates to the field of emergency rescue technology, specifically, to an emergency rescue device. Background Technology

[0002] Statistical analysis of zipline accidents shows that emergency events mainly fall into three categories: natural disasters, passenger injuries, and passengers stranded at high altitudes. Because ziplines are non-powered special equipment, relying entirely on inertia for descent, passenger stranding at high altitudes is the most common emergency. If rescue is not timely, it can easily generate public opinion and negatively impact the scenic area. If the zipline becomes stuck, passengers are too light, or wind resistance prevents passengers and the zipline from reaching the drop-off point and causes them to stop in the middle, rescue is necessary to bring the stranded individuals to safety. Existing rescue methods have the following drawbacks: 1. Long rescue time: Rescuers often rely on experience to control and operate the equipment, resulting in high labor intensity. 2. Manual cable rescue vehicles require rescuers to forcefully swing the rescue vehicle along the steel cable to the required location, thus limiting the rescue distance. 3. Susceptible to the influence of those being rescued: This method is ineffective in situations where the zipline is stuck or passengers are overly frightened and uncooperative. 4. High requirements for the physical fitness and operational skills of rescue personnel.

[0035] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] This embodiment discloses an emergency rescue device. Figure 1 The entire three-dimensional structure of the emergency rescue device is shown. Figure 2 It shows Figure 1 Cross-sectional structure of section A in the middle. Figure 3 It shows Figure 1 The cross-sectional structure at point B.

[0037] Please refer to Figures 1 to 3This utility model discloses an emergency rescue device used to drive a pulley on a cable. The emergency rescue device is located on one side of a rescue winch and includes: a housing 3, a front hook assembly located at one end of the housing 3, a rear hook 1 located at the other end of the housing 3, a control assembly located inside the housing 3, and a traveling assembly located on the upper part of the housing 3. A rescue rope is mounted on the rear hook 1, with one end of the rescue rope attached to the rescue winch. The front hook assembly is used to connect the pulley. The control assembly is used to control the traveling assembly. The traveling assembly is used to drive the housing 3 to move. The emergency rescue device is placed on the wire rope 10. Then, one end of the rescue rope is fixed to the rear hook 1, and the other end is connected to the rescue winch. The control assembly is activated, causing the traveling assembly to drive the housing 3 to move smoothly to the position of the pulley. Next, the front hook assembly is reliably connected to the pulley. Then, by retracting the rescue rope, the housing 3 is smoothly pulled back, and with the help of the front hook assembly, the pulley is pulled to the platform, thus completing the entire rescue process.

[0038] In addition, the control components include: a control box 4, an electromagnetic clutch 17 electrically connected to the control box 4, a motor 12, and a battery 5. The battery 5 provides power to the electromagnetic clutch 17, which is mounted on the walking assembly. The interaction between the motor 12 and the electromagnetic clutch 17 drives the walking assembly, thereby moving the housing 3. The electromagnetic clutch 17 is mounted on the walking assembly; the motor 12 and the battery 5 are electrically connected to the control box 4, and the electromagnetic clutch 17 is electrically connected to the battery 5. The control components ensure the stability and reliability of the entire system under electric drive. Through the operation of the control box 4, the motor 12 can be easily controlled, thus achieving precise operation.

[0039] Furthermore, the motor 12 is a DC motor 12, which is located on the outside of the housing 3, while the battery 5 is located inside the housing 3. The DC motor 12 has advantages such as large starting torque, wide speed range, and high control precision, meeting the needs of rescue equipment that requires precise control of speed and direction. By adjusting the input voltage or current of the motor 12, the running speed of the housing on the wire rope 10 can be smoothly adjusted, thereby meeting the needs of different rescue scenarios. Moreover, because the electromagnetic clutch 17 is de-energized and disengaged, the DC motor 12 is disengaged, thus protecting the DC motor 12 from damage when dragged in the opposite direction.

[0040] Furthermore, the front hook assembly includes: a front hook 7, a front hook bracket 9 disposed on one side of the front hook 7, and a limit switch 19 disposed on the front hook 7; wherein, a limit plate 8 is disposed at the upper end of the front hook 7, and a tension spring 6 is disposed at the lower end of the front hook 7, the tension spring 6 providing a downward force to the front hook 7; the front hook 7 is used to connect to the trolley; the limit plate 8 and the tension spring 6 are used to limit the opening of the front hook 7. When the front hook 7 approaches the trolley hook 11, the front hook 7 of the rescue device is lifted until the trolley hook 11 is fully engaged with the front hook 7 of the rescue device, after which the front hook 7 of the rescue device is lowered by the spring. The front hook 7 has a reverse-lock function; when the rescue device drags the trolley, the front hook 7 is held in a stable connection with the trolley by the downward force exerted by the lower spring. When the trolley hook is hooked by the front hook 7 of the rescue device and dragged in the opposite direction, the tension spring 6 and the limit plate 8 hold the front hook 7 in a relative position, preventing it from opening again. The tension spring 6 and the limiting plate 8 not only ensure stability during connection, but also effectively prevent the front hook 7 from opening accidentally when subjected to excessive force through the combined use of the limiting plate 8 and the tension spring 6, thereby improving the safety of the entire device.

[0041] In this embodiment, the limit switch 19 is a travel switch. When the current hook 7 slides to the trolley hook 11, the trolley hook 11 presses down the limit switch 19, and the limit switch 19 sends a signal to the motor 12, and the motor 12 stops rotating.

[0042] Furthermore, a pin is provided between the front hook 7 and the front hook 7 bracket. The pin further enhances the connection strength between the front hook 7 and the front hook 7 bracket, thereby ensuring the smooth progress of the rescue mission.

[0043] Furthermore, the walking assembly includes: a walking wheel axle 13 disposed inside the housing 3, and a walking wheel 14 disposed on the walking wheel axle 13; wherein, an electromagnetic clutch 17 is disposed on the walking wheel axle 13; one end of the walking wheel axle 13 is connected to the motor 12, and the other end is provided with an axle end baffle 15, which is used to prevent the walking wheel 14 from disengaging from the walking wheel axle 13, thereby improving the reliability and durability of the entire device.

[0044] Furthermore, bearings are provided at both ends of the walking wheel axle 13 and at the connection between the walking wheel axle 13 and the walking wheel 14. The use of bearings 18 reduces the frictional resistance between the walking wheel axle 13 and the axle end baffle 15 and the motor 12, making the walking smoother and also extending the service life of the walking wheel axle 13 and the walking wheel 14.

[0045] Furthermore, an end cap 16 is provided on one side of the shaft end baffle 15. The end cap 16 is used to restrict the movement of the traveling assembly. The end cap 16 not only provides protection but also ensures the stability of the equipment during operation by limiting the range of motion of the traveling assembly.

[0046] Furthermore, buttons are provided on the control box 4. The buttons allow operators to control the system via the control box 4, and the button labels are clear and easy to understand, enabling quick and correct action even in emergencies.

[0047] Furthermore, a baffle 2 is provided on the housing 3 to prevent the wire rope 10 from slipping out of the housing 3 during operation. The baffle 2 can prevent the wire rope 10 from coming out of the housing 3 during equipment operation, thereby avoiding possible dangerous situations. At the same time, the baffle 2 is made of a strong and durable material, which can withstand large impact forces and can operate normally in harsh environments.

[0048] In summary, the emergency rescue device is driven by two DC motors 12, powered by a battery 5 inside the housing 3. A rescue rope is threaded through the rear hook 1, connecting to a rescue winch located on the platform maintenance platform, used to pull the rescue device back to the platform. Normally, the emergency rescue device is placed on the platform. In an emergency, the upper baffle 2 is removed, the device is hung on the wire rope 10, the baffle 2 is attached, and the start button is pressed. The motor 12 rotates, the battery 5 powers the electromagnetic clutch 17, which engages. The motor 12 drives the axle 13 of the traveling wheel, and the electromagnetic clutch 17 drives the traveling wheel 14, allowing the emergency device to reach any position on the wire rope 10. When the emergency rescue device reaches the trolley position, the front hook 7 hooks the trolley hook 11, the limit switch 19 activates, and the motor 12 stops. At this time, the rescue winch on the platform operates, pulling the rescue device and trolley back to the platform.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
