Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a quick-change load device for hoisting training. Background Technology

[0002] With the widespread application of drone technology in logistics, emergency rescue, and material delivery, the demand for drone hoisting operations training is increasing. As a core auxiliary device, the performance of hoisting training payload devices directly determines the training quality and efficiency. Currently available hoisting training payload devices are limited by their structural design and control logic, making it difficult to adapt to the precision and unmanned requirements of modern training.

[0003] Existing hoisting training equipment lacks remote control capabilities. The lowering and retrieval of the hoisting rope requires the operator to manually adjust it at close range or control the rope length by following the drone's movement and manually turning the winch handle, or by connecting the control equipment on the ground via a wired connection. This not only requires an additional 1-2 on-duty personnel, increasing labor costs, but also easily leads to safety risks such as collisions and load falls due to the operator being too close to the drone. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-change load device for hoisting training, which solves the technical problem that existing hoisting training devices lack remote control capabilities and require operators to manually adjust the lowering and retrieval of the hoisting rope at close range.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-change load device for hoisting training includes a drone body. A mounting base is detachably installed on the lower surface of the drone body. Multiple sets of grooves are formed on the lower surface of the mounting base. Hoisting components of hoisting equipment are engaged inside the multiple sets of grooves of the mounting base. A connecting component is installed on the lower surface of the mounting base. Positioning components that limit the position of the mounting base at the lower end of the drone body are installed on the left and right sides of the mounting base.

[0007] Preferably, the hoisting assembly includes multiple sets of positioning rods, which are respectively engaged in multiple sets of grooves in the mounting base. A housing is installed on the lower surface of the multiple sets of positioning rods. A winch body is installed inside the housing. A motor is installed at the outer end of the winch body. The output shaft of the motor is fixedly connected to the rotating shaft of the winch body. A hoisting rope is wound inside the winch body. The end of the hoisting rope away from the winch body passes through the housing and is used to attach the hoisted item.

[0008] Preferably, a hook is installed at the end of the hoisting rope away from the main body of the winch.

[0009] Preferably, the connecting assembly includes a top plate mounted on the lower surface of the mounting base. A connecting plate is provided on the inner wall of the back of the outer casing. An electric telescopic rod is installed on the inner side wall of the connecting plate. A slot is formed at the bottom of the inner wall of the connecting plate. A slider one is slidably connected inside the slot of the connecting plate. The output end of the electric telescopic rod is installed on the side of the slider one near the winch body. A fixing rod is installed at the bottom of the inner wall of the slider one. A sliding groove is formed inside the top plate. A slider two is slidably connected inside the sliding groove of the top plate. The top end of the fixing rod is installed on the lower surface of the slider two.

[0010] Preferably, the positioning component includes multiple sets of latches and multiple sets of locking blocks. The multiple sets of locking blocks are respectively installed on the left and right sides of the main body of the drone, and the multiple sets of latches are respectively installed on the left and right sides of the mounting base. The positions of the multiple sets of locking blocks are respectively located on the rotation path of the multiple sets of latches.

[0011] Preferably, a wireless signal transmitter is provided on the lower surface of the mounting base, and the output end of the wireless signal transmitter is electrically connected to the remote control terminal.

[0012] Preferably, a high-definition camera is mounted on both the front and lower surfaces of the mounting base, and the output end of the high-definition camera is electrically connected to the access end of the wireless signal transmitter.

[0013] Preferably, a limiting block is installed on the outer surface of the suspension rope, and the limiting block is located at the outer end of the outer shell.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the device is in hoisting operation, the training load is attached to the end of the hoisting rope. At this time, the motor is started and rotates forward, and the main body of the winch rotates synchronously to release the hoisting rope. The load is lowered to the designated height with the hoisting rope. When the hoisted goods need to be retrieved, the motor is started to drive the rotating shaft of the main body of the winch to rotate in reverse. The main body of the winch is used to rewind the hoisting rope until the load is close to the bottom of the outer shell. The whole process can be remotely controlled through the ground terminal without the need for manual operation by the operator, thus adapting to the "unattended hoisting training" scenario and improving the practicality of the device.

[0016] 2. When throwing training is required, the electric telescopic rod is activated to push slider one along the slot of the connecting plate, causing the fixed rod and slider two to move synchronously. Slider two is then engaged with the groove inside the top plate, completing the splicing of the connecting assembly. This allows the connecting assembly to position the hoisting assembly at the lower end of the mounting base, preventing the hoisting assembly from moving during use. Conversely, by activating the electric telescopic rod in the opposite direction, slider one is pulled along the slot of the connecting plate away from the hook, causing slider one to move synchronously with the fixed rod. At this time, the connection between the fixed rod and slider two gradually disengages from the groove constraint of the top plate as slider one slides, eventually causing the connecting assembly to disconnect from the fixed connection of the hoisting assembly. This causes the hoisting assembly to lose the support of the connecting assembly, allowing it to fall rapidly under its own weight and the load's weight, completing the throwing action. The entire process has a short response time, thus improving the practicality of the throwing exercise in hoisting training. Attached Figure Description

[0023] This application provides a quick-change load device for hoisting training, which effectively solves the technical problem that existing hoisting training devices lack remote control capabilities and require operators to manually adjust the lowering and retrieval of the hoisting rope at close range.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing hoisting training devices lack remote control capabilities, and the lowering and retrieval of the hoisting ropes require manual adjustment by the operator at close range. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a quick-change load device for hoisting training, including a drone body 1. A mounting base 2 is detachably installed on the lower surface of the drone body 1. Multiple sets of grooves are formed on the lower surface of the mounting base 2, and hoisting components 5 of hoisting equipment are engaged inside the multiple sets of grooves of the mounting base 2. A connecting component 7 is installed on the lower surface of the mounting base 2, and positioning components 3 are installed on the left and right sides of the mounting base 2 to limit the position of the mounting base 2 at the lower end of the drone body 1. Specifically, by activating the hoisting component 5, the height of the moving load at the lower end of the drone body 1 can be adjusted. The entire process can be remotely controlled by a ground terminal without manual operation by the operator, thus adapting to the "unattended hoisting training" scenario and improving the practicality of the device. By activating the connecting component 7, the connecting component 7 can be disconnected and spliced. At this time, the hoisting component 5 falls under the action of gravity, thereby completing the load throwing training.

[0027] The hoisting assembly 5 includes multiple sets of positioning rods 506, which are respectively engaged in multiple sets of grooves in the mounting base 2. A housing 501 is installed on the lower surface of the multiple sets of positioning rods 506. A winch body 504 is installed inside the housing 501. A motor 505 is installed on the outer end of the winch body 504. The output shaft of the motor 505 is fixedly connected to the rotating shaft of the winch body 504. A hoisting rope 502 is wound inside the winch body 504. The end of the hoisting rope 502 away from the winch body 504 passes through the housing 501 and is used to fasten the hoisting item.

[0028] Specifically, when the device is in hoisting operation, the training load is attached to the end of the hoisting rope 502. At this time, the motor 505 is started to rotate forward, and the winch body 504 rotates synchronously to release the hoisting rope 502. The load is lowered to the designated height along with the hoisting rope 502. When the hoisted goods need to be retrieved, the motor 505 is started to drive the rotating shaft of the winch body 504 to rotate in reverse. The winch body 504 is used to wind up the hoisting rope 502 until the load is close to the bottom of the outer shell 501. The whole process can be remotely controlled through the ground terminal without the need for manual operation by the operator, thus adapting to the "unattended hoisting training" scenario and improving the practicality of the device.

[0029] A hook 503 is installed at the end of the hoisting rope 502 away from the main body 504 of the winch. Specifically, the hook 503 is used to replace the hoisting rope 502 to tie the hoisted goods and restrict the position of the hoisted goods at the lower end of the mounting base 2. At this time, the spring-locking hook 503 can quickly attach different types of training loads without additional binding, and the self-locking buckle 301 can prevent the load from falling off during the hoisting process, thereby improving the convenience of load attachment and training safety.

[0030] The connecting assembly 7 includes a top plate 701, which is mounted on the lower surface of the mounting base 2. A connecting plate 702 is provided on the inner wall of the back of the outer casing 501. An electric telescopic rod 703 is installed on the inner side wall of the connecting plate 702. A slot is provided at the bottom of the inner wall of the connecting plate 702. A slider 704 is slidably connected inside the slot of the connecting plate 702. The output end of the electric telescopic rod 703 is installed on the side of the slider 704 near the winch body 504. A fixing rod 706 is installed at the bottom of the inner wall of the slider 704. A sliding groove is provided inside the top plate 701. A slider 705 is slidably connected inside the sliding groove of the top plate 701. The top end of the fixing rod 706 is installed on the lower surface of the slider 705.

[0031] Specifically, when throwing training is required, the electric telescopic rod 703 is activated to push slider 704 along the slot of the connecting plate 702, causing the fixed rod 706 and slider 705 to move synchronously, engaging slider 705 into the slot of the top plate 701, thus completing the splicing of the connecting assembly 7. This allows the connecting assembly 7 to position the hoisting assembly 5 at the lower end of the mounting base 2, preventing the hoisting assembly 5 from moving during use. Conversely, the electric telescopic rod 703 is activated in the opposite direction to pull slider 704 along the slot of the connecting plate 702. The slot of plate 702 slides away from hook 503, causing slider 1 704 to move synchronously with fixed rod 706. At this time, the connection between fixed rod 706 and slider 2 705 gradually breaks away from the constraint of the groove of top plate 701 as slider 1 704 slides. Finally, the connecting component 7 is completely disconnected from the fixed connection with the hoisting component 5, thereby causing the hoisting component 5 to lose the support of connecting component 7, and causing it to fall rapidly under its own weight and the weight of the load, completing the throwing action. The response time of the whole process is short, thereby improving the practicality of the throwing subject in hoisting training.

[0032] The positioning component 3 includes multiple sets of latches 301 and multiple sets of locking blocks 302. The multiple sets of locking blocks 302 are respectively installed on the left and right sides of the UAV body 1, and the multiple sets of latches 301 are respectively installed on the left and right sides of the mounting base 2. The positions of the multiple sets of locking blocks 302 are respectively located on the rotation path of the multiple sets of latches 301. Specifically, by pushing the latches 301 to rotate, the latches 301 are engaged with the outer end of the locking blocks 302. This allows the mounting base 2 to be positioned and unlocked simply by rotating the latches 301 when it is being disassembled or assembled, saving a lot of time compared to the traditional bolt fixing method. The cooperation between the latches 301 and the locking blocks 302 can limit the vertical and horizontal movement of the mounting base 2, reducing the probability of the mounting base 2 becoming loose to zero during training, thereby achieving rapid switching and installation stability of the load components.

[0033] A wireless signal transmitter 6 is installed on the lower surface of the mounting base 2. The output end of the wireless signal transmitter 6 is electrically connected to the remote control terminal. Specifically, the wireless signal transmitter 6 can transmit data such as the length of the hoisting rope 502 and the load height back to the ground terminal in real time. This allows the trainees to monitor the equipment status without having to follow the drone body 1 on the ground, thereby increasing the safe distance between the trainees and the drone body 1 to more than 50m. It also facilitates the recording and analysis of training data, thus realizing remote controllability and data-driven evaluation of hoisting training.

[0034] High-definition cameras 4 are installed on both the front and lower surfaces of the mounting base 2. The output end of the high-definition camera 4 is electrically connected to the access end of the wireless signal transmitter 6. Specifically, the high-definition camera 4 on the front of the mounting base 2 can capture the hoisting environment, and the high-definition camera 4 on the lower surface of the mounting base 2 can capture the load status. The images are transmitted back to the ground terminal through the wireless signal transmitter 6. Trainees can clearly observe the hoisting details and adjust their operations in a timely manner, thereby reducing the error rate of subjects such as load tilt correction and improving the visualization and operational accuracy of hoisting training.

[0035] A limit block 8 is installed on the outer surface of the hoisting rope 502, and the limit block 8 is located at the outer end of the outer shell 501. Specifically, when the winch body 504 winds up the hoisting rope 502, the limit block 8 will abut against the outer end of the outer shell 501 to prevent the hoisting rope 502 from being over-winded and to avoid damage to the outer shell 501 from collision. Since the limit block 8 is made of rubber, it can buffer direct impact force during use, thereby ensuring the safe operation of the equipment and reducing training and maintenance costs.

[0036] Working principle:

[0037] In the first step, when the device is in hoisting operation, the training load is attached to the end of the hoisting rope 502. At this time, the motor 505 is started to rotate forward, and the winch body 504 rotates synchronously to release the hoisting rope 502. The load is lowered to the designated height along with the hoisting rope 502. When the hoisted goods need to be retrieved, the motor 505 is started to drive the rotating shaft of the winch body 504 to rotate in reverse. The winch body 504 is used to wind up the hoisting rope 502 until the load is close to the bottom of the outer shell 501. The whole process can be remotely controlled through the ground terminal without the need for manual operation by the operator, thus adapting to the "unattended hoisting training" scenario and improving the practicality of the device.

[0038] The second step involves activating the electric telescopic rod 703 to push slider 704 along the slot of the connecting plate 702, causing the fixed rod 706 and slider 705 to move synchronously. This engages slider 705 with the groove in the top plate 701, completing the splicing of the connecting assembly 7. This allows the connecting assembly 7 to position the hoisting assembly 5 at the lower end of the mounting base 2, preventing movement of the hoisting assembly 5 during use. Conversely, activating the electric telescopic rod 703 in the opposite direction... Rod 703 pulls slider 704 to slide away from hook 503 along the slot of connecting plate 702, causing slider 704 to move synchronously with fixed rod 706. At this time, the connection between fixed rod 706 and slider 705 gradually breaks away from the groove constraint of top plate 701 as slider 704 slides. Finally, the connecting assembly 7 is completely disconnected from the fixed connection with the hoisting assembly 5, thereby causing the hoisting assembly 5 to lose the support of connecting assembly 7, and causing it to fall rapidly under its own weight and the load weight, completing the throwing action.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
