Technical Field
[0001] This utility model relates to the field of inclined ladder technology, and in particular to a guardrail inclined ladder structure. Background Technology
[0002] As is well known, a guardrail ladder is a facility that combines passage and protection functions. It consists of an inclined ladder body and guardrails on both sides. The ladder body is usually made of metal profiles or concrete and is inclined to connect planes of different heights. The guardrails are fixed vertically or inclined to the two sides of the ladder body, forming a protective barrier through the combination of posts and crossbars. They can extend synchronously with the inclination angle of the ladder body. They are widely used in industrial plants, construction sites, warehouse areas and other scenarios to allow people to safely go up and down platforms of different heights. The guardrails can effectively prevent people from falling accidentally. With their structural stability and protective integrity, they meet the safety requirements for passage through different heights.
[0003] The existing inclined ladders require a lot of manpower to move, and they are not stable structures, which greatly reduces their safety.
[0004] An existing patent (publication number: CN205502997U) discloses a movable inclined ladder, including an inclined ladder body, guardrails on both sides of the inclined ladder body, and a pair of rollers at the lower rear end of the inclined ladder body. The inclined ladder body is composed of several angle steel frames arranged side by side with progressively increasing heights. A steel tread is welded to the upper surface of each angle steel frame. Guardrails are provided on both sides along the direction of increasing height. The rollers are fixed to the rear of the inclined ladder body by a pair of connecting plates welded to the angle steel frames. The distance between the lower end of the rollers and the lower end of the inclined ladder body is 5-15mm. The advantages of this utility model are: the movable inclined ladder achieves easy transport by setting rollers at the bottom rear of the conventional inclined ladder; during normal use, the bottom of the inclined ladder body is in direct contact with the ground, ensuring the stability of the structure; when transporting, the inclined ladder body is tilted backward so that the rollers contact the ground to achieve movement.
[0005] To address the aforementioned issues, existing patents offer solutions. However, when installing inclined ladders to accommodate different height and inclination requirements, the lack of an adaptive structure for the ladder angle prevents quick adjustment of the ladder's angle, thus reducing the ladder's flexibility during installation.
[0006] Therefore, a guardrail inclined ladder structure is proposed. Utility Model Content
[0007] The purpose of this invention is to provide a guardrail inclined ladder structure that can solve the problem of the lack of an adaptive inclined ladder angle structure in the existing system, which makes it impossible to quickly adjust the angle of the inclined ladder under different height and inclination requirements, thus reducing the flexibility of the inclined ladder during installation.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a guardrail inclined ladder structure, comprising a stair slab, an adaptation mechanism, and an assembly mechanism. The adaptation mechanism is disposed on the surface of the stair slab, and the assembly mechanism is disposed on the side of the adaptation mechanism away from the stair slab. The adaptation mechanism includes a positioning rotating rod, an adjusting rotating rod group, a supporting guardrail, and a connecting rotating plate. Two positioning rotating rods are rotatably connected to both sides of the stair slab, and four adjusting rotating rod groups are rotatably connected to the top and bottom sides of both sides of the stair slab away from the positioning rotating rods, respectively. The supporting guardrail is snapped into the top of the adjusting rotating rod group, and two connecting rotating plates are rotatably connected to the top and bottom of the inner side of the positioning rotating rod, respectively. The side of the connecting rotating plate away from the positioning rotating rod is rotatably connected to the adjusting rotating rod group.
[0009] Preferably, the assembly mechanism includes a connecting component and a positioning component, wherein the connecting component is located on the side of the connecting plate away from the stair plate, and the positioning component is located at the bottom of the connecting component.
[0010] Preferably, the connecting assembly includes a connecting rod, a positioning frame, a fixed step, and a limiting guardrail. The connecting rod is rotatably connected to the side of the connecting plate away from the stair tread. The positioning frame is fixedly connected to the side of the connecting rod away from the stair tread. The fixed step is fixedly connected to the inner side of the positioning frame. The two limiting guardrails are respectively fixedly connected to the two sides of the top of the positioning frame.
[0011] Preferably, the positioning component includes a positioning base, a ground plate, and a module connecting plate. The positioning base is fixedly connected to the bottom of the fixed pedal, the ground plate is fixedly connected to the inner side of the positioning base, and the module connecting plate is disposed on the top of the ground plate.
[0012] Preferably, a protective sleeve is fixedly connected to the top of the supporting guardrail, and the surface of the protective sleeve is provided with anti-slip texture.
[0013] Preferably, a reinforcing sleeve is fixedly connected to the top of the adjusting rod assembly, and the inner side of the reinforcing sleeve is engaged with the surface of the supporting guardrail.
[0014] Preferably, an assembly screw is fixedly connected to the side of the connecting rotating rod near the positioning frame, and the side of the assembly screw near the connecting rotating rod passes through the positioning frame and is threadedly connected to the positioning frame.
[0015] Preferably, mounting screws are threaded onto both sides of the top of the module connecting plate, and the bottom of the mounting screws penetrates through the module connecting plate.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This application, by setting up an adaptation mechanism, uses the existing metal stair step structure for the stair treads. Through the limiting structure formed by the positioning rotating rod and the adjusting rotating rod group, each stair tread can be limited, and the connecting rotating plate can also be limited. By rotating the connecting rotating plate and the stair treads on the positioning rotating rod, the adjusting rotating rod group can be driven to perform adaptive orientation adjustment. By adjusting the adaptive orientation of the adjusting rotating rod group, each stair tread can be driven to perform synchronous angle adjustment on the positioning rotating rod. Thus, when the angle of any stair tread adapts to the current required angle as the adjusting rotating rod group adapts, the angles of all stair treads are synchronized. The supporting guardrail is the existing inclined stair railing structure, which can provide protection for users walking on the stair treads. Furthermore, the connecting rotating plate can be connected to the connecting rotating rod.
[0018] 2. This application, by setting up an assembly mechanism, allows the connecting components to cooperate with the positioning components. Through the connecting rotating rods, the positioning frame, and the fixed pedal, a fixed structure is formed. The connecting rotating rods can use the positioning frame as a support point to limit the position of each connecting rotating plate. When the fixed pedal is fixed to the ground at different heights along with the positioning base and the modular connecting plate, the two connecting rotating rods can form the required tilt angle. This allows the connecting rotating plate to connect with the two connecting rotating rods, and the connecting rotating plate can drive the adjusting rotating rod group and the positioning rotating rod to adapt to the mechanism to form an inclined ladder with the required tilt angle. The limiting guardrail can protect the user on the fixed pedal. The grounding plate can use the ground as a support point to limit the position of the modular connecting plate and the positioning base. The modular connecting plate can be further fixed through an external ground connection structure. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 The present invention provides the following technical solution:
[0027] A guardrail-style inclined ladder structure includes a stair slab 1, an adaptation mechanism 2, and an assembly mechanism 3. The adaptation mechanism 2 is disposed on the surface of the stair slab 1, and the assembly mechanism 3 is disposed on the side of the adaptation mechanism 2 away from the stair slab 1. The adaptation mechanism 2 includes positioning rotating rods 21, adjusting rotating rod groups 22, supporting guardrails 23, and connecting rotating plates 24. Two positioning rotating rods 21 are rotatably connected to both sides of the stair slab 1, and four adjusting rotating rod groups 22 are rotatably connected to the top and bottom sides of the stair slab 1 away from the positioning rotating rods 21, respectively. The supporting guardrail 23 is snapped into the top of the adjusting rotating rod groups 22, and two connecting rotating plates 24 are rotatably connected to the top and bottom of the inner side of the positioning rotating rods 21, respectively. The side of the connecting rotating plates 24 away from the positioning rotating rods 21 is rotatably connected to the adjusting rotating rod groups 22.
[0028] In this embodiment: by setting the adaptation mechanism 2, the stair tread 1 is a metal stair step structure in the prior art. The limiting structure formed by the positioning rotating rod 21 and the adjusting rotating rod group 22 can limit the position of each stair tread 1 and limit the position of the connecting rotating plate 24. By rotating the connecting rotating plate 24 and the stair tread 1 on the positioning rotating rod 21, the adjusting rotating rod group 22 can be driven to perform adaptive orientation adjustment. By adjusting the adaptive orientation of the adjusting rotating rod group 22, each stair tread 1 can be driven to perform synchronous angle adjustment on the positioning rotating rod 21. Thus, when the angle of any stair tread 1 adapts to the current required angle as the adjusting rotating rod group 22 adapts, the angles of all stair tread 1 are synchronized. The supporting guardrail 23 is a special guardrail structure for inclined stairs in the prior art, which can provide protection for users walking on the stair tread 1. The connecting rotating plate 24 can be connected to the connecting rotating rod 311.
[0029] Specifically, such as Figure 3 As shown, the assembly mechanism 3 includes a connecting component 31 and a positioning component 32. The connecting component 31 is located on the side of the connecting plate 24 away from the stair plate 1, and the positioning component 32 is located at the bottom of the connecting component 31.
[0030] Specifically, such as Figure 4 As shown, the connecting assembly 31 includes a connecting rod 311, a positioning frame 312, a fixed pedal 313, and a limiting guardrail 314. The connecting rod 311 is rotatably connected to the side of the connecting plate 24 away from the stair tread 1. The positioning frame 312 is fixedly connected to the side of the connecting rod 311 away from the stair tread 1. The fixed pedal 313 is fixedly connected to the inner side of the positioning frame 312. The two limiting guardrails 314 are respectively fixedly connected to the two sides of the top of the positioning frame 312.
[0031] Specifically, such as Figure 5 As shown, the positioning component 32 includes a positioning base 321, a ground plate 322, and a module connecting plate 323. The positioning base 321 is fixedly connected to the bottom of the fixed pedal 313, the ground plate 322 is fixedly connected to the inner side of the positioning base 321, and the module connecting plate 323 is located on the top of the ground plate 322.
[0032] In this embodiment: by setting the assembly mechanism 3, the connecting component 31 can cooperate with the positioning component 32. The connecting rod 311, the positioning frame 312, and the fixed pedal 313 form a fixed structure. The connecting rod 311 can use the positioning frame 312 as a support point to limit the position of each connecting plate 24. When the fixed pedal 313 is fixed on the ground at different heights along with the positioning base 321 and the module connecting plate 323, the two connecting rods 311 can form the required tilt angle. This allows the connecting plate 24 to connect with the two connecting rods 311. The connecting plate 24 drives the adjusting rod group 22 and the positioning rod 21 to form an inclined ladder with the required tilt angle according to the adaptation mechanism 2. The limiting guardrail 314 can protect the user on the fixed pedal 313. The grounding plate 322 can use the ground as a support point to limit the position of the module connecting plate 323 and the positioning base 321. The module connecting plate 323 can be further fixed by the external ground connection structure.
[0033] Specifically, such as Figure 2 As shown, a protective sleeve 25 is fixedly connected to the top of the supporting guardrail 23, and the surface of the protective sleeve 25 is provided with anti-slip texture.
[0034] Specifically, such as Figure 2 As shown, a reinforcing sleeve 26 is fixedly connected to the top of the adjusting rod assembly 22, and the inner side of the reinforcing sleeve 26 is engaged with the surface of the supporting guardrail 23.
[0035] In this embodiment: by setting a protective sleeve 25 and a reinforcing sleeve 26, the protective sleeve 25 can cooperate with the support railing 23. When the user holds the protective sleeve 25 while holding the support railing 23, the anti-slip texture on the surface of the protective sleeve 25 can increase the stability of the user when holding the support railing 23. The reinforcing sleeve 26 can cooperate with the adjusting lever assembly 22. By further limiting the support railing 23 connected to the adjusting lever assembly 22 through the reinforcing sleeve 26, the stability of the adjusting lever assembly 22 and the support railing 23 when connected can be increased.
[0036] Specifically, such as Figure 3 As shown, an assembly screw 315 is fixedly connected to the side of the connecting rod 311 near the positioning frame 312. The side of the assembly screw 315 near the connecting rod 311 passes through the positioning frame 312 and is threadedly connected to the positioning frame 312.
[0037] Specifically, such as Figure 4 As shown, mounting screws 324 are threaded onto both sides of the top of the module connection plate 323, and the bottom of the mounting screws 324 penetrates through the module connection plate 323.
[0038] In this embodiment: by setting an assembly screw 315 and a mounting screw 324, the assembly screw 315 can cooperate with the positioning frame 312. The assembly screw 315 is threadedly connected to the positioning frame 312, which facilitates the removal and installation of the connecting rod 311 from the positioning frame 312 via the assembly screw 315. This improves the flexibility of subsequent installation of the connecting plate 24 and the connecting rod 311. The mounting screw 324 can cooperate with the module connecting plate 323. By the mounting screw 324 penetrating the module connecting plate 323, the module connecting plate 323 can be connected to the ground via the mounting screw 324, thus fixing the module connecting plate 323 to the ground.
[0039] Working principle: First, place the landing plate 322 on the ground at the required different heights. Then, install the connecting rotating plate 24 on the connecting rotating rod 311 at the higher position. Next, tilt the end of the positioning rotating rod 21 and the adjusting rotating rod assembly 22 away from the higher connecting rotating rod 311 downwards until the bottom of the connecting rotating plate 24 is flush with the ground. The connecting rotating plate 24 will then drive the adjusting rotating rod assembly 22 to adjust its position. The stair tread 1 will then rotate adaptively along the positioning rotating rod 21 as the adjusting rotating rod assembly 22 moves, until the stair tread 1 rotates to be flush with the connecting rotating plate 24. Finally, the lower connecting plate 24 is installed on the ground. The rotating rod 311 is connected to the connecting rotating plate 24, and then the module connecting plate 323 is fixed to the ground together with the external ground fixing structure through the external ground fixing structure. At this time, the positioning base 321 will support the positioning frame 312 with the module connecting plate 323 as the support point. Finally, the support guardrail 23 is installed on the top of the adjusting rotating rod group 22, and the limiting guardrail 314 is installed on the top of the positioning frame 312. The user can move up to the fixed step 313 by holding the support guardrail 23 along the path formed by the stair tread 1.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
