Description

Technical Field

[0001] This utility model relates to the field of steel shed structure technology, and in particular to a special U-shaped steel shed. Background Technology

[0002] U-shaped steel sheds are widely used in various engineering and construction fields, such as mine tunnel support, temporary support for underground projects, and the construction of agricultural greenhouses. With the continuous development of industries such as engineering construction and facility agriculture, the demand for U-shaped steel sheds continues to grow, and higher requirements are being placed on their installation efficiency and structural stability during use.

[0003] Currently, the common practice in installing U-shaped steel sheds is to first assemble various types of steel into a frame structure using welding, bolting, and other methods, and then fix the shed roof to the frame to complete the construction. However, this traditional assembly method has significant drawbacks; it is not only time-consuming but also requires a large amount of manpower. Furthermore, some steel sheds adopt a modular design concept, requiring only the following steps during assembly. However, given the strict stability requirements of steel sheds, precise alignment of the frames on two modules is usually necessary during frame assembly. Since there are multiple connection points between the frames of two modules, achieving the connection between modules requires simultaneous alignment at multiple points. This undoubtedly consumes a significant amount of time for adjustment and calibration, and places extremely high demands on the technical skills and operational precision of the construction personnel, leading to numerous difficulties in the alignment process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a special U-shaped steel shed structure, which solves the technical problems of difficult modular assembly and docking, as well as the inconvenience of controlling the rotation, unfolding and closing of the blades.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A special U-shaped steel canopy, comprising: a frame and a canopy surface, with the canopy surface installed on the outer surface of the frame; multiple connecting rods stably mounted on the inner surface of the frame, used for splicing between two frames; inserts located at one end of the connecting rods; slots located at the other end of the connecting rods, adapted to the inserts; and multiple blades rotatably mounted at the end of the slots away from the inserts, which, when rotated and unfolded, form a trumpet shape to guide the insertion of the inserts. The inserts can be square, hexagonal, or other regular polygons, and their shape should consider their fit with the slots and the force distribution to ensure they can withstand the corresponding forces without deformation or damage during splicing. The slots are adapted to the inserts, and their shape and dimensions must be precisely designed to ensure smooth insertion and a stable connection after insertion.

[0006] In a further embodiment, multiple control blocks are provided. The control blocks are stably connected to the blade and are used to control the rotation of the pressure plate. The connection between the control blocks and the blade must ensure a secure connection to prevent connection failure during use. The shape of the control blocks should be rationally designed according to the rotation requirements and stress conditions of the blade, and their size should be moderate, ensuring effective control of the blade rotation without being too large and affecting the compactness of the overall structure. Simultaneously, the control blocks should have sufficient structural strength to withstand the forces generated during blade rotation, preventing deformation or damage.

[0007] In a further embodiment, there are multiple push blocks, and each push block corresponds to a multiple control block. The push blocks are slidably disposed in the slot and are used to push the control blocks to rotate. The material of the push blocks should have a certain hardness and wear resistance to ensure that they will not wear or deform during frequent sliding, thus affecting the effect of pushing the control blocks to rotate. The fit between the push blocks and the inner wall of the slot should ensure smooth sliding, which can be achieved through appropriate machining accuracy and surface treatment.

[0008] In a further embodiment, the movable rod has one end slidably connected to the connecting rod and the other end connected to multiple push blocks. The movable rod is used to limit the sliding distance of the push blocks. The sliding connection of the movable rod within the connecting rod must ensure the straightness of the sliding, which can be achieved by setting a guide rail or a guide structure. The movable rod must be strong enough to withstand the force of the push blocks and avoid bending or deformation during use, which would affect its distance limiting function for the push blocks. The connection between the two ends of the movable rod must be firm to ensure that the connection with the push blocks and the connecting rod will not loosen, so as to ensure the reliability of the system.

[0009] In a further embodiment, a spring is installed inside the connecting rod. One end of the spring is connected to the end of the movable rod away from the push block, and the other end is connected to the connecting rod. The spring is used to push the movable rod to slide towards the push block. The selection of the spring should be based on the required elastic force and stroke of the system to ensure that its elastic performance can meet the movement requirements of the push block. The installation method of the spring should be firm and reliable, and it can be stably installed inside the connecting rod through a mounting base, hook, or other fixing device. The elastic characteristics of the spring should remain stable and not be affected by the external environment (such as temperature, humidity, etc.) to avoid affecting the normal operation of the system.

[0010] In a further embodiment, the number of blades is the same as the number of sides of the insert. The size and shape of the blades are precisely designed according to the number of sides and size of the insert to ensure that the blades do not interfere with each other when they are unfolded and retracted. The rotation range of the blades must meet the guiding requirements for insert insertion. They must remain stable during rotation to avoid jamming or jumping, which would affect the insertion operation of the insert.

[0011] In a further embodiment, the contact surface between the push block and the control block is an inclined surface, with the inclined surface facing the central axis of the connecting rod. The angle of the inclined surface should be reasonably designed according to the sliding distance of the push block and the rotation requirements of the control block to ensure that the control block can be effectively driven to rotate when the push block slides. The surface of the inclined surface should be smooth to avoid excessive friction caused by surface roughness, which would affect the sliding of the push block and the rotation of the control block. At the same time, the shape of the inclined surface should ensure that its mechanical properties will not change due to wear during long-term use, thus affecting the normal operation of the system.

[0012] Beneficial effects: 1. By setting inserts, slots, and rotatable blades around the slots on the connecting rods, multiple blades can be rotated and unfolded into a trumpet shape. When modular assembly is carried out, the trumpet-shaped blades guide the insertion of the inserts. This achieves the goal of quickly and accurately aligning the inserts with the slots and inserting them, effectively reducing the difficulty of docking caused by the need for multiple precise docking points, thereby improving the efficiency of modular assembly. This makes the splicing of the steel shed frame more convenient and efficient, and reduces construction time and labor costs.

[0013] 2. By utilizing the coordination of springs, movable rods, push blocks, control blocks, and insert blocks, the blades can automatically unfold and close. When the insert block is inserted, the control block slides under the action of the insert block, gradually making it fit against the inner wall of the slot. At the same time, the blades will gradually close and fit against the surface of the insert block. After the insert block is pulled out, the spring pushes the movable rod to move the push block towards the control block, causing the control block to rotate towards the central axis of the connecting rod, thereby unfolding the blades.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in this utility model are described clearly and completely. Obviously, the described embodiments are only some, not all, of the embodiments in this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this utility model without creative effort are within the scope of protection of this utility model.

[0021] This application provides a specially structured U-shaped steel canopy, which solves the technical problems of difficult modular assembly and docking, as well as the inconvenience of controlling the rotation, unfolding, and closing of the blades. In practical use, it achieves the goals of improving modular assembly efficiency, reducing docking difficulty, and enabling the blades to automatically unfold and close as the insert blocks are inserted or removed.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-4 A special U-shaped steel canopy structure includes: a frame 1 and a canopy surface 2, wherein the canopy surface 2 is installed on the outer surface of the frame 1; multiple connecting rods 3 are provided, and the multiple connecting rods 3 are stably set on the inner surface of the frame 1, and the connecting rods 3 are used for splicing between two frames 1; an insert block 301 is provided at one end of the connecting rod 3; a slot 302 is opened at the other end of the connecting rod 3, and the slot 302 is adapted to the insert block 301; and multiple blades 4 are provided, and the blades 4 are rotatably set at the end of the slot 302 away from the insert block 301. After the multiple blades 4 are rotated and unfolded, they form a trumpet shape to guide the insertion of the insert block 301.

[0024] The frame 1 supports the canopy 2, and the frame 1 is spliced ​​together by the connecting rod 3 and the plugs 301 and slots 302 at both ends. The plugs 301 are inserted by rotating and unfolding the blade plate 4 into a trumpet shape, which improves the convenience and accuracy of the frame 1 docking during the modular assembly process.

[0025] Multiple control blocks 401 are provided. The control blocks 401 are stably connected to the blade plate 4 and are used to control the rotation of the pressure plate.

[0026] By stably connecting the control block 401 to the blade plate 4, the rotation of the blade plate 4 can be carried out in a preset manner, thereby more accurately assisting the insertion of the plug block 301 and completing subsequent connection actions.

[0027] Multiple push blocks 7 are provided, and the multiple push blocks 7 correspond to multiple control blocks 401. The push blocks 7 are slidably disposed in the slot 302, and the push blocks 7 are used to push the control blocks 401 to rotate.

[0028] Multiple push blocks 7 correspond to control block 401 and slide within slot 302, providing power for controlling the rotation of blade 4 and ensuring that blade 4 can perform corresponding actions according to the insertion of insert block 301.

[0029] The movable rod 6 is slidably connected to the connecting rod 3 at one end and connected to the plurality of pushing blocks 7 at the other end. The movable rod 6 is used to limit the sliding distance of the pushing blocks 7.

[0030] One end of the movable rod 6 is connected to the push block 7, and the other end slides within the connecting rod 3, ensuring that the push block 7 moves within a reasonable stroke range, thereby ensuring the accuracy and stability of the blade 4 rotation.

[0031] Spring 5 is installed inside connecting rod 3. One end of spring 5 is connected to the end of movable rod 6 away from push block 7, and the other end is connected to connecting rod 3. Spring 5 is used to push movable rod 6 to slide towards push block 7.

[0032] Spring 5 is installed inside connecting rod 3, with one end connected to movable rod 6 and the other end connected to connecting rod 3. During the insertion or removal of insert block 301, spring 5 stores or releases energy, pushing movable rod 6 to drive push block 7 to move, thereby realizing the automatic opening and closing of blade 4.

[0033] The number of blades 4 is the same as the number of sides of the insert block 301.

[0034] The number of blades 4 is the same as the number of sides of the insert block 301, ensuring that each side of the insert block 301 can be guided by the corresponding blade 4 during the insertion process, thus improving the stability of the connection.

[0035] The contact surface between the push block 7 and the control block 401 is an inclined surface, and the inclined surface faces the central axis of the connecting rod 3.

[0036] The contact surface between the push block 7 and the control block 401 is an inclined surface facing the central axis of the connecting rod 3. By utilizing the principle of the inclined surface, the push block 7 can smoothly push the control block 401 to rotate when it slides, thereby driving the blade 4 to move.

[0037] During use, multiple blades 4 at the end of slot 302 unfold in a trumpet shape, guiding the insert block 301 to easily align with and insert into slot 302. As the insert block 301 goes deeper, the control block 401 is pushed by the insert block 301 and rotates, gradually fitting against the inner wall of slot 302. The blades 4 then gradually close, eventually fitting against the surface of the insert block 301. During this process, the insert block 301 first contacts the control block 401 and pushes the control block 401 to rotate. When the control block 401 rotates, it drives the push block 7 to slide into the connecting rod 3, thereby pushing the movable rod 6 to compress the spring 5. When disassembly is required, the insert block 301 is pulled out, the spring 5 rebounds and pushes the movable rod 6, causing the push block 7 to move in the opposite direction, pushing the control block 401 to rotate towards the central axis of the connecting rod 3. The blades 4 unfold again in a trumpet shape, preparing for the next splicing.

[0038] The figures shown in the accompanying drawings are illustrative and are intended only to more intuitively demonstrate the key structure and connection relationships of the special U-shaped steel shed of this utility model. In practical applications, the appearance and size of the device can be adjusted and optimized according to specific needs.
