[0002] In helicopter aerial operations, the hook has become a crucial device for lifting and dropping supplies and equipment. To prevent cargo from accidentally falling out of the hook, a guard is designed at the front end of the hook. The existing guard rotates around its axis. When loading cargo, the guard is simply rotated upward and lifted, and the cargo eye is passed through the gap between the guard and the hook end to hang it onto the hook. However, during helicopter flight, the hook is subject to vibration, and there is a risk that the guard could jump upward, causing the cargo to accidentally fall out of the hook. Utility Model Content

[0003] In order to solve the problem in the prior art that during the flight of a helicopter, the hanging is in a vibrating environment, causing the guard to jump upward, which easily leads to the abnormal release of the cargo from the hook, the present application provides a guard locking device for the hanging to solve the above problem.

[0004] In order to achieve the above objectives, the technical solutions adopted in this application are:

[0005] A guard locking device for hanging, comprising a guard and a locking device arranged on a hanging device, wherein the locking device is used to limit the rotation of the guard;

[0006] The locking device includes a rotating electromagnet, a transfer component and a locking arm. The transfer component is detachably and rotatably connected to the end face of the rotating electromagnet. A connecting rod is provided between the locking arm and the transfer component. The two ends of the connecting rod are respectively hinged to the transfer component and the locking arm.

[0007] As a further improvement of the present invention, the rotating electromagnet includes a magnet body and a wire. The magnet body is fixedly mounted on the side wall of the suspension. The wire is electrically connected to the magnet body for energizing the magnet body.

[0008] As a further improvement of the present invention, the adapter component includes an adapter plate and a fixed seat. The adapter plate is installed on an output shaft set in the magnet body through multiple bolts. The output shaft is used to drive the adapter plate to rotate. The fixed seat is installed on the adapter plate and is hinged to the connecting rod.

[0009] As a further improvement of the present invention, a first hinge seat is provided inside the fixing seat, one end of the connecting rod is inserted into the first hinge seat, and hinged by inserting a first rotating shaft.

[0010] As a further improvement of the present invention, the locking arm includes a first part, a second part, and a third part that are connected to each other. A second hinge seat is provided inside the first part, and the other end of the connecting rod is inserted into the second hinge seat, and the hinge is achieved by inserting a second rotating shaft.

[0011] As a further improvement of the present invention, the second part is in the shape of a circular ring, and the second part is rotatably mounted on the side wall of the suspension through a mounting hole provided inside the second part.

[0012] As a further improvement of the present invention, the third portion is in the shape of a long plate, and rounded edges are provided on both sides of the third portion close to the top end of the guard hook.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages and effects:

[0014] 1. In this application, the locking device is designed to prevent the guardrail from jumping upward under vibration conditions, thereby preventing the cargo from accidentally unhooking. The guardrail and the locking device are both installed on the hanging device. When the built-in weighing system of the helicopter's hanging device detects that the cargo is loaded, the system will supply power to the rotating electromagnet through a wire. This causes the output shaft of the rotating electromagnet to rotate counterclockwise to an appropriate angle, and then drives the locking arm to rotate counterclockwise through the connecting rod, and causes the third part of the locking arm to enter the circumferential rotation range of the guardrail, thereby limiting the guardrail and restricting its upward rotation to achieve the locking function. The above-mentioned entire process is controlled by the electromagnet, and the weighing information can be used to complete the automatic control of the guardrail locking device, avoiding manual operation and greatly improving work efficiency and safety. In addition, the design of the locking device also fully considers the influence of environmental factors, such as air flow fluctuations or mechanical vibrations that the helicopter may encounter during flight, and can maintain the stable state of the locking arm without weakening the locking effect.

[0028] Example:

[0029] Combined with the accompanying drawings Figure 1-Figure 5 As shown, a locking device 20 for a guard hanger 10 for hanging includes a guard hanger 10 and a locking device 20 arranged on the hanging device, wherein the locking device 20 is used to limit the rotation of the guard hanger 10; the locking device 20 includes a rotating electromagnet 210, an adapter component 220 and a locking arm 260, and the adapter component 220 is detachably rotatably connected to the end face of the rotating electromagnet 210, and a connecting rod 230 is provided between the locking arm 260 and the adapter component 220, and the two ends of the connecting rod 230 are respectively hinged to the adapter component 220 and the locking arm 260.

[0030] To illustrate, in the locking device 20 of the guard hook 10, a rotating electromagnet 210 serves as a driving element, controlling the swing angle of the locking arm 260 through its rotation. When the electromagnet is energized, the rotor inside it rotates, driving the adapter component 220 with it. The adapter component 220 is hinged to one end of the connecting rod 230, causing the connecting rod 230 to rotate with it. The other end of the connecting rod 230 is hinged to the locking arm 260, transmitting the rotational motion to the locking arm 260, which in turn drives the locking arm 260 to rotate until it reaches the desired position, thereby locking the guard hook 10.

[0031] Specifically, when the locking arm 260 is rotated to the appropriate position, it can restrict the rotation of the guard hanger 10, ensuring that the hanging device remains stable during operation. When the guard hanger 10 needs to be released, the rotating electromagnet 210 is de-energized, and the adapter component 220 and locking arm 260 return to their initial positions, releasing the lock and allowing the guard hanger 10 to rotate freely.

[0032] Brief description of working principle:

[0033] Both the guardrail 10 and the locking device 20 are mounted on the hanging device. When the helicopter's hanging device's built-in weighing system detects that cargo is loaded, the system supplies power to the rotating electromagnet 210 via wire 2120. This causes the output shaft of the rotating electromagnet 210 to rotate counterclockwise to an appropriate angle, which in turn drives the locking arm 260 counterclockwise via the connecting rod 230. This causes the third portion 2640 of the locking arm 260 to enter the circumferential rotation range of the guardrail 10, thereby limiting the guardrail 10's upward rotation and achieving the locking function.

[0034] It is worth noting that the relative positions of the hook 30 and the guard 10 in the actual hanging device are as shown in the accompanying drawings of the specification. Figure 5 As shown, the two can rotate around their rotation axes respectively. When the goods do not need to be hung on the hook 30, the guard hanger 10 is in the first position 40. When the goods need to be loaded onto the hook 30, the guard hanger 10 rotates clockwise to the second position 50, so that a gap is formed between the hook 30 and the guard hanger 10, so that the lifting ring of the goods can pass through the gap to complete the loading of the goods.

[0035] It is worth noting that when the cargo is delivered, the hanging weighing system detects that the load weight becomes 0, and the rotating electromagnet 210 is powered off and rotates clockwise to reset to the initial position. The overall relative position is shown in the accompanying figure of the specification. Figure 3 As shown, at the same time, the adapter plate 2210 also rotates clockwise under the drive of the electromagnet, and through the connection of the connecting rod 230, drives the locking arm 260 to rotate clockwise to the initial position. At this time, the locking arm 260 is no longer within the rotation path range of the guard hanger 10 and no longer has a limiting effect on the guard hanger 10. The guard hanger 10 can rotate freely upward around its rotation axis, thereby completing another cargo loading.

[0036] Combined with the accompanying drawings Figure 1-Figure 5 As shown, the rotating electromagnet 210 includes a magnet body 2110 and a wire 2120 . The magnet body 2110 is fixedly mounted on the side wall of the suspension. The wire 2120 is electrically connected to the magnet body 2110 for energizing the magnet body 2110 .

[0037] For clarity, wire 2120 extends from magnet body 2110 and is connected to a power supply or control system via the internal wiring system of the suspension device. In practical applications, the wiring of wire 2120 must ensure that it is not damaged or interfered with during the movement of the suspension device, while also ensuring sufficient flexibility to accommodate the movement requirements of the suspension device under different operating conditions.

[0038] Furthermore, the magnet body 2110 must be secured in a manner that ensures it remains stable during operation of the suspension device and prevents displacement due to vibration or impact. Typically, the magnet body 2110 is attached to the sidewall of the suspension device via bolts 270, welding, or other mechanical fastening methods. To improve system reliability, the magnet body 2110 should be secured at a location with high structural strength.

[0039] Combined with the accompanying drawings Figure 1-Figure 5 As shown, the adapter component 220 includes an adapter plate 2210 and a fixed seat 2220. The adapter plate 2210 is installed on the output shaft set in the magnet body 2110 through multiple bolts 270. The output shaft is used to drive the adapter plate 2210 to rotate. The fixed seat 2220 is installed on the adapter plate 2210 and is hinged to the connecting rod 230. A first hinge seat is provided inside the fixed seat 2220. One end of the connecting rod 230 is inserted into the first hinge seat and is hinged by inserting a first rotating shaft 240.

[0040] To clarify, adapter plate 2210 is connected to the output shaft of rotating electromagnet 210, and its rotation directly affects the swing of locking arm 260. The combination of adapter plate 2210 and fixing base 2220 not only ensures the stability and durability of adapter component 220 but also provides a reliable hinge point for connecting rod 230. The first hinge seat design within fixing base 2220 enables smooth rotation of connecting rod 230, thereby ensuring that locking arm 260 accurately reaches the predetermined position.

[0041] In practical applications, the materials and manufacturing process of the adapter component 220 are also very important. Typically, the adapter plate 2210 and the fixing base 2220 are made of high-strength metal materials, such as aluminum alloy or stainless steel, to ensure good performance even in harsh operating environments. In addition, surface treatments such as anodizing or plating on the adapter component 220 can further improve its corrosion resistance and wear resistance, thereby extending the service life of the entire locking device 20.

[0042] To ensure the reliability of the locking device 20 under various operating conditions, the adapter component 220 may also be designed with anti-loosening measures. For example, a spring washer or lock nut may be used at the bolt 270 to prevent loosening due to vibration. Furthermore, the hinged structure between the adapter component 220 and the connecting rod 230 must also ensure good rotational flexibility and stability even after extended use.

[0043] Combined with the accompanying drawings Figure 1-Figure 5As shown, the locking arm 260 includes a first part 2610, a second part 2620, and a third part 2640 that are connected to each other. A second hinge seat is opened inside the first part 2610, and the other end of the connecting rod 230 is inserted into the second hinge seat and is hinged by inserting a second rotating shaft 250. The second part 2620 is rotatably installed on the side wall of the suspension through the mounting hole 2630 opened inside. The third part 2640 is also provided with rounded edges on both sides near the top of the guard 10.

[0044] To illustrate, the first portion 2610, serving as the main body of the locking arm 260, is connected to the connecting rod 230 via a second hinged joint, ensuring precise swinging of the locking arm 260 in response to the electromagnet's drive. The second portion 2620 connects to the side wall of the hanger via mounting holes 2630, providing a stable support point and ensuring that the locking arm 260 remains stable even under the weight of the cargo. The rounded edge design of the third portion 2640 near the top of the guardrail 10 not only reduces wear on the guardrail 10 but also prevents it from accidentally moving upward when locked.

[0045] In practical applications, the material selection for locking arm 260 is also crucial. Typically, locking arm 260 is made of high-strength metal, such as carbon steel or a special alloy, to ensure it does not deform or break under heavy loads. Furthermore, surface treatments such as heat treatment or surface coating can further enhance its wear and corrosion resistance, ensuring that locking device 20 maintains optimal operating conditions in a variety of environments.

[0046] To further enhance the reliability of the locking device 20, the design of the locking arm 260 may also include additional anti-loosening measures. For example, the connection between the second hinged seat and the connecting rod 230 may be secured with a self-locking nut or welded to prevent loosening in a vibrating environment, thereby ensuring that the connection maintains good strength even after extended use.

[0047] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
