[0017] Beneficial effects of this application

[0018] By incorporating stairs inside the tower, the stairs can be better integrated with the tower structure, reducing obstruction of the observation view and improving the observation effect. Compared with the existing straight ladders, the zigzag staircases reduce the climbing difficulty for the staff and reduce the physical exertion during the climb, making the climb more stable and comfortable and avoiding the risk of falling due to fatigue or loss of balance. At the same time, the design of the stairs allows the staff to free up their hands to carry equipment while climbing.

[0019] The standardized design of the standard section makes the installation process simpler and faster, reducing installation costs and time. At the same time, the standard section is easy to disassemble and replace, which facilitates the maintenance of the tower.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0042] This application proposes a watchtower with a folding ladder, such as Figures 1 to 13As shown, the structure includes: a tower body 100, a platform 300, a guardhouse 600, and a staircase; the platform 300 is located at the top of the tower body 100, the guardhouse 600 is located on the top surface of the platform 300, and the platform 300 has an access opening 510; the staircase is located inside the tower body 100; the staircase includes: two or more folding ladders 200; the two or more folding ladders 200 are arranged in a zigzag pattern along the length of the tower body 100, with the topmost folding ladder 200 protruding from the tower body 100 and connecting to the access opening 510, and the bottom of the bottommost folding ladder 200 being suitable for contact with the installation ground; a step 240 is provided between each two adjacent folding ladders 200; the tower body 100 includes: multiple standard sections arranged in sequence, and a connecting section is provided between each two adjacent standard sections. The frame 130 includes a folding ladder 200 in each standard section; treads 240 are located at the connection between two adjacent standard sections, and the two ends of each folding ladder 200 are connected to the upper and lower treads 240 respectively; each standard section includes four uprights 110 and two or more V-shaped support rods 120, the four uprights 110 are arranged opposite each other, and the four uprights 110 of any standard section are fixedly connected to the four uprights 110 of the adjacent standard sections above and below through the first connecting assembly 131; each pair of adjacent uprights 110 is provided with a support rod 120, and the open end of the support rod 120 faces the installation ground, the tip of the support rod 120 is connected to the connecting frame 130, and the two ends of the open end of the support rod 120 are fixedly connected to the first connecting assembly 131.

[0043] It should be noted that the tower body 100 is responsible for bearing the weight of the overall structure and external loads, providing stable support for the platform 300 and the guardhouse 600. The platform 300 is located at the top of the tower body 100 structure, providing a spacious working space for the guards, enabling them to easily conduct observation and monitoring work. The guardhouse 600 is fixedly installed on the top surface of the platform 300, providing a relatively comfortable indoor space for the guards, allowing them to stay for extended periods to continuously observe the surrounding area. The staircase is located inside the tower body 100 and connects the bottom and top of the tower body 100 to the platform 300, providing a path for the guards to move up and down.

[0044] like Figures 1 to 7As shown, the zigzag arrangement of the folded ladder 200 can more effectively utilize the internal space of the tower body 100, distribute the pressure of the ladder on the structure of the tower body 100, reduce the single-point stress, and thus improve the overall structural stability. At the same time, the zigzag arrangement design can reduce the steepness of the ladder, ensuring smooth passage for on-duty personnel and reducing the risk of slipping or falling. The bottom of the folded ladder 200, located at the bottom, is in contact with the installation ground, providing a stable support foundation for the entire ladder, preventing the ladder from swaying or sinking during use, and ensuring the stability of the ladder. For safety, the topmost folding ladder 200 extends out of the tower body 100 and connects to the access opening 510, which provides a convenient access passage for duty personnel. Duty personnel can easily enter the access opening 510 on the platform 300 from the stairs, and then enter the platform 300 or the duty pavilion 600. The step 240 is suitable for providing a temporary rest platform 300 for duty personnel. During the climb of the stairs, duty personnel can naturally adjust their foot position and body center of gravity on the step 240 to ensure that they can continue to move forward in a more stable and safer state.

[0045] By incorporating stairs inside the tower body 100, the stairs can be better integrated with the tower body 100, reducing obstruction of the observation view and improving the observation effect. Compared with the existing straight ladders, the zigzag staircases reduce the climbing difficulty for duty personnel and reduce the physical exertion during the climb, making the climbing process more stable and comfortable for duty personnel. This avoids the risk of duty personnel falling due to fatigue or loss of balance. At the same time, the design of the stairs allows duty personnel to free up their hands to carry equipment while climbing the stairs.

[0046] like Figures 1 to 4 As shown, the main body of the connecting frame 130 is a square structure. The four corners of the connecting frame 130 are fixedly set at the connection of two adjacent standard sections. The square structure of the connecting frame 130 can provide stable and reliable support between adjacent standard sections, avoiding relative displacement or swaying between two adjacent standard sections. At the same time, the connecting frame 130 can better bear and transmit the load on the tower body 100, enhance the stability of the overall structure of the tower body 100, and ensure that the watchtower remains stable and reliable during long-term use. The step 240 is fixedly set on the connecting frame 130 and located at the connection of two adjacent standard sections. The folding ladder 200 is fixed inside the standard section by the upper and lower step 240.

[0047] like Figures 1 to 4As shown, the four columns 110 are parallel to each other in their length direction. The support rod 120 is set between any two adjacent columns 110, and the two ends of the opening of the support rod 120 are fixedly connected to the bottom of the two adjacent columns 110 through the first connecting component 131. The two adjacent columns 110 and the support rod 120 together form a triangular support structure. The design of the support rod 120 further enhances the stability of the standard section. When bearing a large load, the support rod 120 can share part of the load, reduce the burden on the columns 110, and improve the load-bearing capacity of the standard section. The four columns 110 of any standard section are fixedly connected to the four columns 110 of the adjacent standard sections above and below through the first connecting component 131, thereby forming a stable and continuous support structure. This allows the tower body 100 to effectively resist the influence of external loads such as wind pressure and snow pressure, improving the stability of the entire tower. The standardized design of the standard section makes its installation process simpler and faster, reducing installation costs and time. At the same time, the standard section is also easy to disassemble and replace, providing convenience for the maintenance of the tower body 100.

[0048] Furthermore, such as Figure 2 , Figure 4 As shown, both the column 110 and the support rod 120 are made of angle steel. The cross-section of the first connecting component 131 is L-shaped and matches the column 110. The column 110 of any standard section abuts against the column 110 of the adjacent standard sections above and below. The two adjacent columns 110 are set in the opening of the first connecting component 131, and the first connecting component 131 is fixed at the connection of the two columns 110 by high-strength bolts and self-tapping screws. The plane of the connecting frame 130 is perpendicular to the length direction of the column 110, and the four corners of the connecting frame 130 are located at the connection of the two adjacent columns 110. The connecting frame 130 is fixed at the connection of the first connecting component 131 by high-strength bolts and self-tapping screws, thereby realizing the support frame fixed at the connection of the two adjacent standard sections. The two ends of the opening of the support rod 120 are fixedly connected to the first connecting component 131 by high-strength bolts and self-tapping screws.

[0049] Preferably, the main body of the standard section is a cube-shaped frame structure, and the length of the column 110 of each standard section is 2m. The four columns 110 are arranged in pairs opposite each other, and the preset distance between each pair of adjacent columns 110 is 2m.

[0050] In one possible implementation, a second connecting component 132 is also included; the second connecting component 132 is fixedly disposed on the connecting frame 130, and the tip of the support rod 120 is fixedly connected to the connecting frame 130 through the second connecting component 132.

[0051] It should be noted here that, as Figures 1 to 4As shown, the second connecting component 132 is fixedly mounted on the connecting frame 130 and located between two adjacent first connecting components 131. The second connecting component 132 is fixedly connected to the connecting frame 130 and the tip of the support rod 120 respectively by high-strength bolts and self-tapping screws. The design of the second connecting component 132 makes the connection between the support rod 120 and the connecting frame 130 more reliable. When the watchtower is subjected to various external forces, the force borne by the support rod 120 can be accurately transmitted to the connecting frame 130 through the second connecting component 132, and then distributed to the entire tower body 100 structure, thereby enhancing the overall stability of the watchtower.

[0052] Furthermore, such as Figure 4 As shown, a guardrail 121 is installed inside the opening of the "V"-shaped structure of the support rod 120, and the guardrail 121 is arranged adjacent to the tread 240. The guardrail 121 is located inside the opening of the support rod 120, and both ends of the support rod 120 are fixedly connected to the inner wall of the support rod 120. The guardrail 121 provides a safe barrier for the staff on duty when climbing the stairs, preventing them from falling due to slips or accidents when turning or resting at the tread 240, thus ensuring the safety of the stairs during use.

[0053] Preferably, there are two or more guardrails 121, and the two or more guardrails 121 are fixedly installed in the opening of the support rod 120, and the two or more guardrails 121 are arranged parallel to each other in the length direction.

[0054] In one possible implementation, a first base plate 140 is provided at the bottom of the lowest standard section, which is suitable for fixing the tower body 100 to the mounting base.

[0055] It should be noted here that, as Figure 1 , Figure 12 As shown, the first column base plate 140 includes a first base plate 141 and a first reinforcing plate 142. The bottoms of the four columns 110 of the standard section at the bottom are all fixedly connected to the first base plate 141. The first base plate 141 is suitable for fixing the tower body 100 on the installation ground. The first reinforcing plate 142 is located between the top surface of the column 110 and the first base plate, and the plane of the first reinforcing plate 142 is perpendicular to the plane of the first base plate 141. The first reinforcing plate 142 connects the first base plate 141 and the column 110, increasing the contact area and connection points between the two, and improving the connection strength and stability between the column 110 and the first base plate 141. When the tower body 100 is subjected to external force, the first reinforcing plate 142 can distribute the load it bears to the first base plate 141, ensuring that the tower body 100 can be stably installed on the installation ground.

[0056] Furthermore, the first base plate 141, the first reinforcing plate 142, and the column 110 are fixedly connected by welding. Welding ensures a tight connection between the first base plate 141, the first reinforcing plate 142, and the column 110, thereby enhancing the strength and rigidity of the overall structure. At the same time, welding can effectively reduce on-site work and improve overall construction efficiency.

[0057] Furthermore, such as Figures 1 to 3 As shown, the main body of the standard section at the bottom has a stepped structure that is smaller at the top and larger at the bottom. The stepped structure of the standard section allows the bottom of the tower body 100 to have a larger contact area with the installation ground, which can better distribute the overall weight of the tower body 100, provide solid and reliable support for the tower body 100, effectively prevent the tower body 100 from tilting or sinking due to excessive load, and improve the overall load-bearing capacity of the tower body 100.

[0058] Preferably, the distance between the upper ends of any two adjacent columns 110 of the four columns 110 located at the bottom is 2m, and the distance between the lower ends of any two adjacent columns 110 is 2.5m.

[0059] In one possible implementation, such as Figures 4 to 6 As shown, each folding ladder 200 includes two ladder beams 210, two or more step bars 220, and handrails 230; the length directions of the two ladder beams 210 are parallel to each other, the two or more step bars 220 are arranged between the two ladder beams 210, and the handrails 230 are arranged on the two ladder beams 210.

[0060] It should be noted that the two ladder beams 210 are used to provide a support structure for the step rods 220. The two ends of the step rods 220 are fixedly connected to the two ladder beams 210 by welding. The parallel design of the two ladder beams 210 can evenly distribute the load, thereby transferring the weight of the on-duty personnel to the tower body 100 through the step rods 220, ensuring the stability and safety of the folding ladder 200 during use. The length direction of two or more step rods 220 is perpendicular to the length direction of the ladder beams 210, and the two or more step rods 220 are perpendicular to the length direction of the ladder beams 210. The stair rails 220 are equidistantly spaced along the length of the ladder, and the stair rails 220 are equidistantly spaced and perpendicular to the ladder beams 210. This design ensures that the user's feet can be stably placed on the stair rails 220. When the climber's feet step on the stair rails 220, the vertical design allows the feet to be placed naturally, enabling the climber to exert force more easily and move up or down more easily. The handrails 230 are fixedly installed on the two ladder beams 210. The handrails 230 are used to provide safety protection for the staff when going up and down the stairs, preventing the staff from falling due to loss of balance when going up or down the folding ladder 200.

[0061] Furthermore, such as Figure 5As shown, the bottom of the bottom folding ladder 200 is provided with a fixed base plate 260. The main body of the fixed base plate 260 is a rectangular plate structure, and the plane where the fixed base plate 260 is located is set at an angle of 56.3° with the folding ladder 200. The fixed base plate 260 is fixedly connected to the pre-embedded bolts on the installation ground, thereby firmly fixing the folding ladder 200 to the installation ground.

[0062] Preferably, the angle between the length direction of each folding ladder 200 and the horizontal plane is 56.3°, the width of the folding ladder 200 ranges from 615mm to 650mm, the step height of the folding ladder 200 is 200mm, and the step distance of the folding ladder 200 is 133mm. The 200mm step height design avoids the risk of climbers losing their balance due to lifting their legs too high. At the same time, the 133mm step distance ensures that there is enough support space between the feet to prevent slipping due to insufficient foot spacing. This design allows climbers to maintain body stability during climbing and to better control their bodies in case of emergencies, reducing the occurrence of safety accidents.

[0063] In one possible implementation, such as Figures 4 to 6 As shown, it also includes a ladder beam connecting plate 242; the tread 240 is fixedly installed on the connecting frame 130, and one end of the ladder beam 210 is placed on the tread 240 and fixedly connected to the tread 240 through the ladder beam connecting plate 242.

[0064] It should be noted that each mounting frame is equipped with two footplate beams 241. The two footplate beams 241 are arranged in a V-shape and are fixedly connected to the connecting frame 130 by high-strength bolts. The footplate 240 is fixedly installed on the connecting frame 130 through the footplate beams 241. The footplate beams 241 and the connecting frame 130 together provide stable support for the footplate 240, ensuring that the footplate 240 will not shake or shift during use, thus improving the stability of the entire structure. The ladder beam connecting plate 242 firmly connects the folding ladder 200 and the footplate 240 together. When people walk on the folding ladder 200, the ladder beam connecting plate 242 can ensure the effective transfer of load between the folding ladder 200 and the footplate 240.

[0065] In one possible implementation, platform 300 includes a platform frame and walkway 430; the main body of the platform 300 frame has a square grid structure, and the walkway 430 is fixedly laid on the side of the platform 300 frame away from the standard section.

[0066] It should be noted here that, as Figure 8 , Figure 9As shown, the square grid structure of the platform 300 frame provides good stability. Due to the symmetry of the square grid, the force transmission is more balanced, reducing the possibility of deformation or damage to the platform 300 frame caused by excessive local stress, and enhancing the overall load-bearing capacity of the platform 300. The walkway 430 provides a safe and stable passage space for duty personnel and equipment. When on duty, the duty personnel can move freely on the walkway 430 of the platform 300 to meet their work needs.

[0067] Specifically, such as Figure 9 As shown, the platform 300 frame includes four side beams 310, two main beams 320, two crossbeams 330, a first beam 340, a second beam 350, an opening secondary beam 520, and two or more struts 360. The four side beams 310 are connected end to end to form a square frame. The two main beams 320 and the two crossbeams 330 are arranged parallel to each other within the frame, and the length directions of the main beams 320 and the crossbeams 330 are perpendicular to each other. The intersections of the main beams 320 and the crossbeams 330 are connected by a main-secondary beam connecting plate 301 and fixed with high-strength bolts. The first beam 340 is located between the two main beams 320 and is connected to the two crossbeams 330 through a secondary beam connecting plate 302. The second beam 350 is fixed with high-strength bolts. It passes through one of the main beams 320 and the first beam 340 in sequence and then connects with another main beam 320. The intersection of the second beam 350 and the main beam 320 is connected by the main-secondary beam connecting plate 301 and fixed with high-strength bolts. The intersection of the second beam 350 and the first beam 340 is connected by the secondary beam connecting plate 302 and fixed with high-strength bolts. The secondary beam 520 of the opening is located between the two cross beams 330, and there is a preset distance between the secondary beam 520 of the opening and the main beam 320 to form an access opening 510. Two or more support rods 360 are arranged crosswise inside the frame, and the length direction of the two or more support rods 360 is located on the 45-degree diagonal of the frame.

[0068] like Figure 13 As shown, a lower support connecting plate 410 is provided at the intersection of the main beam 320 and the cross beam 330. Correspondingly, the top of the four columns 110 of the standard section located at the top of the tower body 100 structure 100 is provided with a first column top plate 150. The lower support connecting plate 410 and the first column top plate 150 are fixed with high-strength bolts, thereby fixing the platform 300 to the top of the tower body 100 structure 100.

[0069] In one possible implementation, such as Figure 8 As shown, it also includes a first fence 440; the main body of the first fence 440 is a fence frame structure with bends, and the first fence 440 is set on the frame of the platform 300 and located at the access opening 510.

[0070] It should be noted that the opening of the first fence 440 faces the side of the guard booth 600; the bottom of the first fence 440 is fixedly equipped with a fence connector, and the first fence 440 is connected to the secondary beam 520 of the opening through the fence connector and is fixed with high-strength bolts. The L-shaped structure of the first fence 440 can guide personnel to enter the platform 300 through the access opening 510 correctly, while preventing the personnel on duty from accidentally falling from the access opening 510 when walking on the platform 300.

[0071] In one possible implementation, such as Figure 8 As shown, it also includes a second fence 450; the second fence 450 is set around the perimeter of the platform 300 frame. It should be noted that there are four second fences 450, and each of the four second fences 450 is set on the four side beams 310 by fence connectors and fixed by high-strength bolts.
