[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a turnover protection device that can be adapted to different floors. The turnover protection device that can be adapted to different floors includes a suspension ladder mechanism 1 and a stepping plate mechanism 2. By arbitrarily installing and disassembling the suspension ladder mechanism 1 on the stepping plate mechanism 2, the installation efficiency of the stairs can be improved and manpower and material costs can be saved.

[0039] The suspension ladder mechanism 1 is the basic support structure of the entire protective device, including a suspension ladder frame 11. Multiple hexagonal rods 12 are fixedly connected to one side of the suspension ladder frame 11. The design of the hexagonal rods 12 not only effectively enhances the structural strength of the suspension ladder frame 11, making it stable and less prone to deformation when bearing heavy loads, but also provides workers with more ergonomic footholds based on the rotation angle of the suspension ladder. A gear block 13 is fixedly connected to one end of the suspension ladder frame 11, providing a basis for the transmission and cooperation between the entire device and other components. Through the cooperation of the gear block 13 and subsequent mechanisms, the suspension ladder will not rotate after installation, ensuring stability.

[0040] The stepping plate mechanism 2 includes a stepping plate 21 set at one end of the suspended ladder frame 11. The stepping plate 21 is the part that the operator steps on. During installation, workers can use cranes or other aerial work platforms to pre-install it in a suitable position. The operator can also lay down a soft pad to cover the connecting groove 22 so that the operator can step on it. A connecting groove 22 is opened on one side of the stepping plate 21. A pressing plate 23 is movably installed in the connecting groove 22. The movable design of the pressing plate 23 is the key to realizing various subsequent functions. By operating the pressing plate 23, the coordinated work of other components in the connecting groove 22 can be triggered, thereby realizing the adjustment and control of the protective device.

[0041] Example 2

[0042] Reference Figures 2 to 15This is the second embodiment of the present invention, which is based on the previous embodiment.

[0043] The pressing plate 23 has a threaded hole 23-1, which is used to connect and cooperate with other components with threaded structures. The threaded connection enables the fastening and detachable installation of components. At the same time, the threaded hole 23-1 cooperates with the subsequent mechanism to provide power support for the drive of the subsequent mechanism. A square groove 23-2 is provided on one side of the pressing plate 23, which provides movement space for the rotation of the suspension mechanism 1. A toothed groove 23-4 and a toothed column 23-3 are fixedly connected to one side of the pressing plate 23. The toothed groove 23-4 and the toothed column 23-3 provide conditions for the transmission and positioning between the pressing plate 23 and other components. The toothed groove 23-4 can mesh with components with toothed structures to realize the transmission of power and the control of movement. The toothed column 23-3 can cooperate with holes or grooves on other components to play a positioning and limiting role, ensuring that the pressing plate 23 maintains an accurate position during movement.

[0044] The connecting groove 22 is equipped with a pushing component 24, including a pushing plate 24-1 disposed inside the connecting groove 22. The pushing plate 24-1 has a moving groove 24-2 inside, which provides space for the movement of other components, enabling relative movement between the components. One side of the moving groove 24-2 extends through one side of the pushing plate 24-1. This through-through design facilitates the insertion of other components into the moving groove 24-2 from the side to achieve connection and transmission. One side of the pushing plate 24-1 has multiple limiting holes 24-3, which cooperate with the toothed column 23-3. When the pressing plate 23 moves, the toothed column 23-3 can be inserted into the limiting holes 24-3, thereby restricting the movement of the pushing plate 24-1, locking the position of the pushing component 24, and ensuring the stability of the device during operation.

[0045] The connecting groove 22 is equipped with a clamping member 25, including a movable plate 25-1 that is slidably disposed inside the movable groove 24-2. The movable plate 25-1 can slide within the movable groove 24-2, thereby driving the first clamping plate 25-2 and the second clamping plate 25-3 to move. The first clamping plate 25-2 is fixedly connected to one side of the movable plate 25-1, and the second clamping plate 25-3 is fixedly connected to one side of the movable plate 25-1. The width of the first clamping plate 25-2 is greater than that of the second clamping plate 25-3. This different width setting is intended to allow the suspension mechanism 1 to be inserted into the connecting groove 22. When the gear block 13 is inside the groove 22, it will not contact the second clamping plate 25-3, but will contact the first clamping plate 25-2 behind it. This will cause the gear block 13 to drive the first clamping plate 25-2 and move the entire clamping member 25. The moving plate 25-1 has multiple braking holes 25-4 on one side, which cooperate with the toothed column 23-3. When the pressing plate 23 moves, the toothed column 23-3 can be inserted into the braking hole 25-4 to restrict the sliding of the moving plate 25-1, thereby fixing the position of the clamping member 25 and ensuring that the clamped object will not fall off.

[0046] A sliding groove 21-1 is provided on one side of the inner wall of the pedal 21. A transmission block 26 is symmetrically slidably arranged inside the sliding groove 21-1. One end of the transmission block 26 is fixedly connected to one side of the push plate 24-1. The sliding groove 21-1 provides a track for the sliding of the transmission block 26, so that the transmission block 26 can move stably inside the pedal 21. Through the fixed connection between the transmission block 26 and the push plate 24-1, when the transmission block 26 slides in the sliding groove 21-1, it can drive the push plate 24-1 to move, thereby realizing the movement of the pusher 24, and then driving the clamping member 25 and other components to work. This transmission method can accurately transmit power to each component and ensure the normal operation of the device.

[0047] A rotating groove 21-2 is provided on one side of the foot pedal 21. The rotating groove 21-2 provides space for the rotation and accommodation of the rotating component 27. The rotating component 27 is provided in the rotating groove 21-2. The rotating component 27 includes a rotating ring 27-1 rotatably disposed inside the rotating groove 21-2. The outer wall of the rotating ring 27-1 is provided with a thread 27-2, which cooperates with the threaded hole 23-1. When the rotating ring 27-1 rotates in the rotating groove 21-2, the cooperation between the thread 27-2 and the threaded hole 23-1 can drive the pressing plate 23 to move in the connecting groove 22, so that the tooth 23-4 meshes with the gear block 13, so that the suspension mechanism 1 will not rotate after installation and fixation. At the same time, the tooth 23-3 engages with the brake hole 25-4 on the moving plate 25-1, thereby restricting the movement of the moving plate 25-1 and completing the horizontal fixation of the gear block 13.

[0048] A rotating column 27-3 is rotatably arranged inside the rotating ring 27-1. An actuating groove 27-4 is opened at the bottom of the rotating column 27-3. An actuating column 27-5 is movably arranged in the actuating groove 27-4. One side of the actuating column 27-5 is fixedly connected to one side of the transmission block 26. When the rotating column 27-3 rotates, the rotational motion of the rotating column 27-3 can be converted into the movement motion of the actuating column 27-5 through the cooperation of the actuating groove 27-4 and the actuating column 27-5. This causes the transmission block 26 to slide in the sliding groove 21-1. Driven by the transmission block 26, the pushing member 24 moves so that the first clamping plate 25-2 and the second clamping plate 25-3 completely enclose the gear block 13.

[0049] A first safety element 28 is provided on one side of the rotating column 27-3, including a first actuating groove 28-1 opened on one side of the rotating column 27-3. A first spring 28-2 is fixedly connected to one side of the first actuating groove 28-1. A first actuating rod 28-3 is fixedly connected to one end of the first spring 28-2. A first pin block 28-4 is fixedly connected to one side of the first actuating rod 28-3. When it is necessary to fix the relative position of the rotating column 27-3 and the rotating ring 27-1, the first actuating rod 28-3 is actuated, so that the first pin block 28-4 is inserted into the first pin groove 28-6. At this time, the first spring 28-2 is in a compressed state. Through the elastic force of the first spring 28-2, the first pin block 28-4 can be tightly fixed in the first pin groove 28-6, thereby locking the rotating column 27-3 and the rotating ring 27-1, preventing the rotating column 27-3 from rotating freely in the rotating ring 27-1, and ensuring the safety and stability of the device during operation.

[0050] A locking ring 28-5 is fixedly connected to one side of the foot pedal 21. The locking ring 28-5 has a first pin groove 28-6 inside, which cooperates with the first pin block 28-4. The first pin groove 28-6 provides a space for the first pin block 28-4. Through the cooperation between the first pin groove 28-6 and the first pin block 28-4, the first safety element 28 is locked.

[0051] A second safety element 29 is provided on one side of the rotating ring 27-1, including a second actuating groove 29-1 opened on one side of the rotating ring 27-1, a second spring 29-2 fixedly connected to one side of the inner wall of the second actuating groove 29-1, a second actuating rod 29-3 fixedly connected to one end of the second spring 29-2, a second pin block 29-4 fixedly connected to one side of the second actuating rod 29-3, and a second pin groove 29-5 opened on the inner wall of the sliding groove 21-1, which cooperates with the second pin block 29-4. When it is necessary to fix the relative position of the rotating ring 27-1 and the pedal 21, the safety element 29 is provided. When in use, the second lever 29-3 is moved, causing the second pin block 29-4 to insert into the second pin groove 29-5. At this time, the second spring 29-2 is in a compressed state. Through the elastic force of the second spring 29-2, the second pin block 29-4 can be tightly fixed in the second pin groove 29-5, thereby locking the rotating ring 27-1 with the pedal 21. This further enhances the stability and safety of the device, prevents the rotating ring 27-1 from rotating freely in the rotating groove 21-2, and ensures that the entire turnover protection device can work reliably during use.

[0052] In use, firstly, according to different floor heights, the position and angle of the suspension ladder frame 11 are adjusted by the gear block 13 of the suspension ladder mechanism 1 in cooperation with the external transmission device. The hexagonal rod 12 ensures that the suspension ladder frame 11 remains stable during the adjustment process. The operator sets the position of the foot pedal 21 in advance and pushes the gear block 13 forward toward the connecting groove 22. At this time, the gear block 13 will not contact the second clamping plate 25-3, but will contact the first clamping plate 25-2 behind it, so that the gear block 13 drives the first clamping plate 25-2 and moves the entire clamping component 25.

[0053] After adjusting to the appropriate angle, the first actuating lever 28-3 is moved to disengage the first pin block 28-4 from the first pin groove 28-6. At this time, the first spring 28-2 is in a stretched state, releasing the first pin block 28-4 from its limit in the first pin groove 28-6. Then, the rotating column 27-3 is rotated, and through the cooperation of the actuating groove 27-4 and the actuating column 27-5, the rotational motion is converted into the movement of the transmission block 26, which in turn drives the transmission block 26 to slide in the sliding groove 21-1. Driven by the transmission block 26, the pushing member 24 moves so that the first clamping plate 25-2 and the second clamping plate 25-3 completely enclose the gear block 13.

[0054] At this point, based on the same principle as above, the limit of the second safety component 29 is released, and the rotating ring 27-1 is rotated. During this process, the rotating column 27-3 rotates independently relative to the rotating ring 27-1. At this time, the thread 27-2 on the rotating ring 27-1 and the threaded hole 23-1 cooperate with each other, so that the rotation of the rotating ring 27-1 drives the pressing plate 23 to move downward. The toothed thread 23-4 fixedly connected on one side of the pressing plate 23 meshes with the teeth on the gear block 13, ensuring that the suspension mechanism 1 will not rotate. At the same time, the toothed column 23-3 moves and engages with the brake hole 25-4 on the moving plate 25-1, thereby restricting the movement of the moving plate 25-1 and completing the horizontal fixation of the gear block 13. At this point, the fixation of the entire device is completed.

[0055] If the rotation angle of the suspension mechanism 1 needs to be adjusted, simply rotate the rotating ring 27-1 by a certain angle. At this time, the teeth 23-4 disengage from the teeth on the gear block 13, but the gear post 23-3 will not be completely removed from the brake hole 25-4 on the moving plate 25-1. The operator can then adjust the rotation angle as needed.

[0056] By using the portable installation and disassembly of the suspension ladder mechanism 1 on the stepping plate mechanism 2, compared with the existing technology, the installation efficiency is high, the operation is flexible, and the manpower and material costs are saved.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
