Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0017] Example 1

[0018] Please see Figure 1-12 This utility model provides a technical solution: a fall-prevention cargo lifting platform, including a load-bearing plate 1, a lifting assembly 2, a enclosure assembly 3, and a protective assembly 4. The lifting assembly 2 includes a scissor lift platform 21 and several electric wheels 22. The enclosure assembly 3 includes a storage box 31, enclosure panels 32, and an electric telescopic rod 33. The protective assembly 4 includes a first arc-shaped frame 41, a second arc-shaped frame 42, and a load-bearing ring 43. The top surface of the load-bearing plate 1 has an annular groove 11, and the load-bearing ring 43 is located within the annular groove 11, with its top surface flush with the top surface of the load-bearing plate 1. In this embodiment, there are four enclosure assemblies 3 and two protective assemblies 4. In use, the output end of the electric telescopic rod 33 first shortens, driving the enclosure panels 32 into the storage box 31, allowing workers to move goods to the top of the load-bearing plate 1. During the process of moving goods, the concave surfaces of the first arc-shaped frame 41 and the second arc-shaped frame 42 face each other, preventing goods from occupying the inner space of the annular groove 11 of the load-bearing plate 1. After the goods are stacked on top of the support plate 1, the worker walks between the first arc-shaped frame 41 and the second arc-shaped frame 42, and stands inside the support ring 43. At this time, the second arc-shaped frame 42 separates the worker from the goods. Then, the worker faces the goods and holds onto the second arc-shaped frame 42 with both hands. Next, the output end of the electric telescopic rod 33 extends, pulling the enclosure 32 away from the storage box 31. When the storage box 31, the enclosure 32, and the first arc-shaped frame 41 form a closed ring structure, it prevents the worker from falling. Subsequently, the device moves to a suitable position via the electric wheels 22, and the scissor lift 21 lifts the support plate 1 to transport the goods and the worker. During this process, because the worker holds onto the second arc-shaped frame 42, he can ensure his own stability. Even if the goods sway, the worker's body will not collide with the goods, avoiding injury.

[0019] Please see Figure 11-12When the top surface of the support plate 1 is flush with the top surface of the elevated platform, the output end of the electric telescopic rod 33 near the elevated platform shortens again, causing the enclosure plate 32 to enter the storage box 31. Then, the worker manually rotates the second arc-shaped frame 42, which rotates the support ring 43 along with it. The support ring 43 slides along the inner wall of the annular groove 11, preventing contact between the support ring 43 and the worker's feet. When the second arc-shaped frame 42 rotates behind the worker, there is no obstruction between the worker and the goods, and the worker's movement space on the top surface of the support plate 1 is expanded, allowing the worker to easily transfer goods to the top surface of the elevated platform.

[0020] Example 2

[0021] Based on Example 1, please refer to Figure 1-2 and Figure 5-9 The protective assembly 4 also includes two third arc-shaped frames 44, which are respectively located on both sides of the second arc-shaped frame 42. The first end of each third arc-shaped frame 44 has a pivot 441, and the second end has a locking assembly 45. The locking assembly 45 includes a rod 451, and a slot 421 is provided on the side wall of the second arc-shaped frame 42. When a worker stands inside the support ring 43 and faces the goods, they can pull the second end of the third arc-shaped frame 44 by hand, causing the third arc-shaped frame 44 to rotate on the top surface of the support plate 1 via the pivot 441. When the second end of the third arc-shaped frame 44 approaches the end of the second arc-shaped frame 42, the worker inserts the rod 451 into the slot 421. At this time, the third arc-shaped frame 44 is connected to the second arc-shaped frame 42, and the rod 451 prevents the second arc-shaped frame 42 from moving. This ensures that even if the worker grips the second arc frame 42 tightly while the scissor lift platform 21 is raising the support plate 1, the second arc frame 42 and the support ring 43 will not rotate, further increasing the worker's stability.

[0022] Please see Figure 5-9 The locking assembly 45 also includes a drive plate 452 and a protruding plate 453. The third arc-shaped frame 44 has an assembly cavity 442 inside, and the drive plate 452 is located within the assembly cavity 442, which communicates with the through hole 443. The slot 421 has extension grooves 422 at both its top and bottom. When the third arc-shaped frame 44 and the second arc-shaped frame 42 need to be connected, the insertion rod 451 drives the drive plate 452 and the protruding plate 453 to move together. The drive plate 452 slides along the inner wall of the assembly cavity 442, and the insertion rod 451 slides along the inner wall of the through hole 443. The drive plate 452 prevents the insertion rod 451 from disengaging from the third arc-shaped frame 44. When the insertion rod 451 enters the slot 421, the protruding plate 453 enters the extension groove 422.

[0023] Please see Figure 5-9The locking assembly 45 also includes an adjusting block 454. The assembly cavity 442 penetrates the side wall of the third arc-shaped frame 44 near the first arc-shaped frame 41. The adjusting block 454 has a gripping hole 4542. The operator can reach into the gripping hole 4542 to grasp the adjusting block 454, which in turn moves the drive plate 452, the insert rod 451, and the protruding plate 453 together. When the third arc-shaped frame 44 needs to be separated from the second arc-shaped frame 42, the operator pulls the adjusting block 454 to disengage the insert rod 451 from the slot 421 and the protruding plate 453 from the extension groove 422. Since the protruding plate 453 cannot enter the through hole 443, the locking assembly 45 will not detach from the third arc-shaped frame 44. The side wall of the adjusting block 454 is provided with an arc-shaped cutting surface 4541. When the third arc-shaped frame 44 is separated from the second arc-shaped frame 42, the operator pushes the third arc-shaped frame 44 to rotate, so that the second end of the third arc-shaped frame 44 is close to the first arc-shaped frame 41. The arc-shaped cutting surface 4541 can ensure that the adjusting block 454 and the first arc-shaped frame 41 will not collide, thus avoiding damage to the locking component 45.

[0024] Please see Figure 1-2 and Figure 5-12 The distance between the first end of the third arc-shaped frame 44 and the second arc-shaped frame 42 is greater than the distance between the second end of the third arc-shaped frame 44 and the second arc-shaped frame 42, so the operator can adjust the state of the locking component 45 without having to reach forward. The distance between the second end of the third arc-shaped frame 44 and the second arc-shaped frame 42 is greater than the distance between the first end of the third arc-shaped frame 44 and the first arc-shaped frame 41. When the third arc-shaped frame 44 and the second arc-shaped frame 42 are connected together, the first arc-shaped frame 41, the second arc-shaped frame 42, and the two third arc-shaped frames 44 form a closed ring structure, which increases the stability of the operator and prevents the operator from falling.

[0025] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
