Description

Technical Field

[0001] This utility model relates to the field of staircase and walkway technology, and more specifically, to a staircase and walkway that is easy to transport and use. Background Technology

[0002] In construction sites, maintenance work, and temporary passageway construction scenarios, stair walkways serve as critical access facilities, primarily used in stairwell areas to provide safe and stable passageways for workers and equipment. Traditional stair walkways mostly employ fixed structures, forming an integral frame through welding or bolting. While structurally robust, these structures are cumbersome to assemble and disassemble, requiring specialized tools and personnel, and are time-consuming. Although some modular walkways support disassembly and assembly, the complex design of connecting components makes them prone to issues such as lost or damaged parts, affecting reusability. These problems make traditional stair walkways unsuitable for transport and handling needs. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a staircase walkway that is easy to transport and use, thereby solving the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A staircase walkway for easy transport includes a trailer frame, a folding ladder, and a support assembly. The trailer frame includes a rectangular frame with a first hinge position and a second hinge position on the front inner side of the rectangular frame. Rollers are provided at the bottom of the rectangular frame. The bottom of the folding ladder is hinged to the first hinge position and the second hinge position. A connecting plate is provided at the top of the folding ladder. The support assembly includes an upper fixed plate and a lower fixed plate located at the rear of the folding ladder. Slide rails are provided on the two fixed plates, and a sliding plate is slidably mounted on the slide rails. A telescopic rod is provided between the sliding plate and the rectangular frame.

[0006] Furthermore, the folding ladder includes two parallel first connecting rods and two parallel second connecting rods located below them. An anchor rod is provided on the outer side of the first connecting rod near the bottom, which is connected to the first hinge position. The same anchor rod is provided on the outer side of the second connecting rod near the bottom, which is connected to the second hinge position. Several steps are provided between the first connecting rod and the second connecting rod.

[0007] Furthermore, the docking plate is disposed on the top pedal, and an elongated hole is provided on the docking plate.

[0008] Furthermore, the front sides of the upper fixing plate and the lower fixing plate are fixedly mounted on the rear sides of the two second connecting rods, and there are two slide rails, which are arranged parallel between the two fixing plates, and the slide rails are located at the left and right edges of the fixing plates.

[0009] Furthermore, a first anchoring hole is provided on the rear side of the upper fixing plate, a second anchoring hole is provided on the rear side of the lower fixing plate, and a third anchoring hole and a fourth anchoring hole are provided on the rear side of the sliding plate from top to bottom. The four anchoring holes are the same size, and during the movement of the sliding plate, the third anchoring hole / the fourth anchoring hole can coincide with the first anchoring hole / the second anchoring hole.

[0010] Furthermore, a first baffle is provided on the rear side of the upper fixing plate above the first anchoring hole, and a second baffle is provided on the rear side of the lower fixing plate below the second anchoring hole. When the sliding plate abuts against the upper fixing plate, the third anchoring hole coincides with the first anchoring hole.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] like Figure 1-6 As shown, this utility model provides a staircase walkway that is easy to transport, including a trailer frame 1, a folding ladder 2, and a support assembly 3. The trailer frame 1 includes a rectangular frame 11, with a first hinge position 12 and a second hinge position 13 respectively provided on the front inner side of the rectangular frame 11. Rollers 14 are provided at the bottom of the rectangular frame 11. The bottom of the folding ladder 2 is hinged to the first hinge position 12 and the second hinge position 13 respectively. A connecting plate 24 is provided at the top of the folding ladder 2. The support assembly 3 includes an upper fixing plate 31 and a lower fixing plate 32 provided on the rear side of the folding ladder 2. The two fixing plates are provided with... A slide rail 33 is provided, and a sliding plate 34 is slidably mounted on the slide rail 33. A telescopic rod 35 is provided between the sliding plate 34 and the rectangular frame 11. When in use, the sliding plate 34 on the support assembly 3 is moved to the lower fixed plate 32 for fixing. At the same time, the telescopic rod 35 is adjusted according to the height of the working layer of the stairs so that the top connecting plate 24 of the folding ladder 2 contacts the working layer. Then, it is fixed to the connecting plate 24 with screws, thus completing the unfolding. When it is necessary to retract, the sliding plate 34 is moved to the upper fixed plate 31 for fixing, and then the telescopic rod 35 is retracted so that the folding ladder 2 completely falls onto the trailer frame 1.

[0027] In this embodiment, the folding ladder 2 includes two parallel first connecting rods 21 and two parallel second connecting rods 22 located below them. An anchor rod is provided on the outer side of the first connecting rod 21 near the bottom, which is connected to the first hinge position 12. The same anchor rod is provided on the outer side of the second connecting rod 22 near the bottom, which is connected to the second hinge position 13. A plurality of steps 23 are provided between the first connecting rod 21 and the second connecting rod 22.

[0028] The docking plate 24 is set on the top step 23, and the docking plate 24 has an elongated hole. The docking plate 24 facilitates the fixing of the folding ladder 2 to the upper working layer after it is unfolded. That is, the docking plate 24 is fixed to the working layer by anchoring structures such as screws, thereby restricting the movement of the trailer frame 1 in the moving state. At the same time, the roller 14 is preferably a fuma wheel, which has a built-in braking function. After the docking plate 24 is installed in place, the fuma wheel can be limited, increasing the stability of the overall structure.

[0029] like Figure 4-5As shown, in the support assembly 3, the front sides of the upper fixed plate 31 and the lower fixed plate 32 are fixedly mounted on the rear side of the two second connecting rods 22. There are two slide rails 33, which are arranged in parallel between the two fixed plates, and the slide rails 33 are located at the left and right edges of the fixed plates.

[0030] Furthermore, the upper fixing plate 31 has a first anchoring hole 312 on its rear side, the lower fixing plate 32 has a second anchoring hole 322 on its rear side, and the sliding plate 34 has a third anchoring hole 341 and a fourth anchoring hole 342 on its rear side from top to bottom. The four anchoring holes are the same size. During the movement of the sliding plate 34, the third anchoring hole 341 / fourth anchoring hole 342 can coincide with the first anchoring hole 312 / second anchoring hole 322.

[0031] Furthermore, a first baffle 311 is provided on the rear side of the upper fixed plate 31 above the first anchoring hole 312, and a second baffle 321 is provided on the rear side of the lower fixed plate 32 below the second anchoring hole 322. When the sliding plate 34 abuts against the upper fixed plate 31, the third anchoring hole 341 coincides with the first anchoring hole 312. When the sliding plate 34 abuts against the lower fixed plate 32, the fourth anchoring hole 342 coincides with the second anchoring hole 322. When support is needed, the sliding plate 34 is moved to the lower fixed plate 32, and bolts are used to pass through the second anchoring hole 322 and the fourth anchoring hole 342 sequentially from the rear side of the lower fixed plate 32, and then fixed with nuts. The unfolding angle of the folding ladder 2 can be adjusted by the telescopic rod 35. When the sliding plate 34 is moved to the upper fixed plate 31, the folding ladder 2 can be folded.

[0032] In this embodiment, a reinforcing rib is provided between the top of the first baffle 311 and the upper fixing plate 31, and a reinforcing rib is provided between the bottom of the second baffle 321 and the lower fixing plate 32.

[0033] In this embodiment, a crossbar 15 is provided on the rear inner side of the rectangular frame 11, and first hinge seats are provided on both sides of the top of the crossbar 15.

[0034] Furthermore, a second hinge seat is provided on the rear side of the sliding plate 34 near both ends. A telescopic rod 35 is provided between the first hinge seat and the second hinge seat on the same side. The telescopic rod 35 consists of two square tubes sleeved together, with several through holes on the outer side of the two tubes. After adjusting the length, the final adjustment of its length is achieved by inserting an anchor rod into a set of overlapping through holes.

[0035] As a preferred embodiment, such as Figure 6As shown, two pads 16 are provided on the top rear side of the rectangular frame 11. When the folding ladder 2 is fully folded, the telescopic rod 35 abuts against the pads 16. In the current structure, the folding ladder 2 and the rectangular frame 11 cannot be completely overlapped, and there is also a support component 3 between them. The telescopic rod 35 is in contact with the rectangular frame 11. In order to avoid local stress and compression deformation, the pads 16 are provided to increase the stress area, thereby protecting the structure.

[0036] Specifically, the working principle of this easy-to-transfer staircase walkway is as follows: The bottom of the trailer frame 1 is equipped with a swivel wheel. The folding ladder 2 is hinged to the trailer frame 1 via the first and second hinge points 13. When the sliding plate 34 of the support component 3 slides along the slide rail 33 to the lower fixed plate 32, it is fixed with bolts through the anchoring holes. At this time, the telescopic rod 35 adjusts the unfolding angle of the folding ladder 2 so that the top connecting plate 24 (with elongated holes) is anchored to the working layer, forming a stable passageway. When retracting, the sliding plate 34 moves to the upper fixed plate 31 for fixation. The telescopic rod 35 is adjusted to make the folding ladder 2 fall onto the trailer frame 1. With the help of the pad block 16, the pressure is dispersed and the structure is protected. Through the above structure, the problem of the cumbersome disassembly and assembly process of the existing staircase walkway and its inconvenience for transportation and use is solved.

[0037] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
