Description

Technical Field

[0001] This utility model relates to the field of inclined passage technology, and in particular to an inclined passage for a ladder cage. Background Technology

[0002] During construction, traditional vertical ladders or simple passageways are no longer sufficient to meet the needs of construction workers for quick and safe movement, nor are they conducive to material transportation. Inclined ladder cages offer a more convenient and efficient mode of access, improving construction efficiency and ensuring personnel safety.

[0003] Currently, the existing technology of inclined ladder cages is an integrated design that is inconvenient to transport. Furthermore, since the fence and main board are integrated, it is difficult to disassemble and replace them at low concentrations. Moreover, the overall length of the main board cannot be adjusted according to actual needs, which has significant limitations and poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies where the integrated design is inconvenient to transport, the fence and main board are integrated, making it difficult to disassemble and replace, and the overall length of the main board cannot be adjusted according to actual needs, resulting in significant limitations and poor practicality. Therefore, a ladder cage inclined channel is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ladder cage inclined channel, including a main board, a screw rod inside the main board, a secondary plate threadedly connected to the outer wall of the screw rod, the secondary plate being slidably connected to the main board, and one end of the secondary plate penetrating the main board; first railings are provided on both sides of the top of the main board, and mounting plates are fixed to the opposite ends of the two first railings; the two mounting plates are fixed to the main board by a plurality of second bolts; a second railing is slidably connected to one end of each of the two first railings; a connecting block is fixed to the end of each of the two second railings outside the first railings; the connecting block is fixed to the secondary plate by a pin.

[0006] Preferably, a connecting post is fixed to one end of the screw, and the end of the connecting post away from the screw passes through the main board and is fixed with a rotating plate. A damping ring is installed inside the main board, and the connecting post is rotatably connected to the main board through the damping ring.

[0007] Preferably, a support plate is fixed to one end of the main board, a first bolt is provided inside the support plate, the output end of the first bolt is located inside the rotating plate, and a plurality of limiting holes matching the first bolt are provided on the outer wall of the rotating plate.

[0008] Preferably, both ends of the sub-plate are fixed with first limiting blocks, and both ends of the inner wall of the main plate are provided with first limiting grooves that match the first limiting blocks.

[0009] Preferably, a second limiting block is fixed at both ends of the second fence, and a second limiting groove matching the second limiting block is opened at both ends of the inner wall of the first fence.

[0010] Preferably, both the main board and the sub-board are fixed with connecting steel frames at their bottom ends, and each of the two connecting steel frames has multiple mounting holes.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, by rotating the rotating plate, the connecting column rotates, which in turn drives the screw to rotate. This allows the sub-plate to move under the constraints of the first limiting block and the first limiting groove, thereby adjusting the distance between the sub-plate and the main plate at the end furthest from the main plate. This expands the overall length of the main plate, enhancing its practicality. Furthermore, through the telescopic effect of the sub-plate, it can retract into the main plate when not in use, reducing its overall volume and facilitating transportation. The mounting plate and the second bolt allow for the installation and removal of the first fence. On one hand, when the first fence is damaged, it can be replaced individually. On the other hand, the installation and removal design allows the first fence and the main plate to be stacked for easy transportation, further enhancing its practicality.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a ladder cage inclined channel, including a main board 1, a screw 2 inside the main board 1, a secondary plate 3 threadedly connected to the outer wall of the screw 2, the secondary plate 3 being slidably connected to the main board 1, and one end of the secondary plate 3 penetrating the main board 1, the top two sides of the main board 1 are provided with first railings 12, the opposite ends of the two first railings 12 are fixed with mounting plates 14, the two mounting plates 14 are fixed to the main board 1 by a plurality of second bolts 13, one end of the two first railings 12 is slidably connected with a second railing 15, the end of the two second railings 15 located outside the first railings 12 is fixed with a connecting block 18, the connecting block 18 being fixed to the secondary plate 3 by a pin 19.

[0021] The effect achieved by the entire embodiment 1 is that, by rotating the screw 2, the sub-plate 3 can move under the limitation of the first limiting block 4 and the first limiting groove 5, thereby adjusting the distance between the end of the sub-plate 3 away from the main plate 1 and the main plate 1. This allows for length adjustment according to the distance between the ladder cage and the circumferential platform. After adjustment, the opposite ends of the main plate 1 and the sub-plate 3 are welded to the ladder cage and the circumferential platform respectively. By pulling the second fence 15, the second fence 15 covers the sub-plate 3. The pin 19 passes through the connecting block 18 and is located inside the sub-plate 3, thereby fixing the position of the sub-plate 3. The installation plate 14 and the second bolt 13 allow for the installation and removal of the first fence 12. On the one hand, when the first fence 12 is damaged, it can be replaced separately. On the other hand, the installation and removal design allows the first fence 12 and the main plate 1 to be stacked for storage, which is convenient for transportation and has greater practicality.

[0022] Example 2, as Figure 1-4As shown, a connecting post 6 is fixed to one end of the screw 2. The end of the connecting post 6 away from the screw 2 passes through the main board 1 and is fixed to a rotating plate 8. A damping ring 7 is installed inside the main board 1. The connecting post 6 is rotatably connected to the main board 1 through the damping ring 7. A support plate 10 is fixed to one end of the main board 1. A first bolt 11 is provided inside the support plate 10. The output end of the first bolt 11 is located inside the rotating plate 8. Multiple limiting holes 9 matching the first bolt 11 are opened on the outer wall of the rotating plate 8. A first limiting block 4 is fixed to both ends of the sub-plate 3. A first limiting groove 5 matching the first limiting block 4 is opened on both ends of the inner wall of the main board 1. A second limiting block 16 is fixed to both ends of the second fence 15. A second limiting groove 17 matching the second limiting block 16 is opened on both ends of the inner wall of the first fence 12. A connecting steel frame 20 is fixed to the bottom of the main board 1 and the sub-plate 3. Multiple mounting holes 21 are opened in both connecting steel frames 20.

[0023] The overall effect of Embodiment 2 is that by rotating the rotating plate 8, the connecting column 6 rotates, which in turn rotates the screw 2. This allows the sub-plate 3 to move under the limitation of the first limiting block 4 and the first limiting groove 5, thereby adjusting the distance between the end of the sub-plate 3 away from the main plate 1 and the main plate 1, thus expanding the overall length of the main plate 1 and improving its practicality. After adjustment, simply inserting the first bolt 11 through the support plate 10 and into the limiting hole 9 on the outer wall of the rotating plate 8 can limit the position of the rotating plate 8, preventing it from rotating on its own and improving stability. Through the connection of the steel frames 20, the two steel frames 20 can be placed on the protrusions of the ladder cage and the circumferential platform, respectively. Welding allows the two steel frames 20 to be fixed to the ladder cage and the circumferential platform. The mounting holes 21 allow for installation by rotating screws or welding, further enhancing practicality.

[0024] Working principle: When using this device, the user rotates the rotating plate 8, which drives the connecting column 6 to rotate, thereby driving the screw 2 to rotate. This allows the sub-plate 3 to move under the limitation of the first limiting block 4 and the first limiting groove 5, thereby adjusting the distance between the end of the sub-plate 3 away from the main plate 1 and the main plate 1. This allows for length adjustment according to the distance between the ladder cage and the circumferential platform. After adjustment, simply insert the first bolt 11 through the support plate 10 and into the limiting hole 9 on the outer wall of the rotating plate 8 to limit the position of the rotating plate 8 and prevent it from rotating on its own. Then, through the setting of the connecting steel frame 20, the two connecting steel frames 20 can be placed on the protrusions of the ladder cage and the circumferential platform respectively. Through welding, the two connecting steel frames 20 can be fixed to the ladder cage and the circumferential platform. By pulling the second fence 15, the second fence 15 covers the sub-plate 3. The pin 19 passes through the connecting block 18 and is set inside the sub-plate 3 to fix the position of the sub-plate 3.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
