The device includes a base with protective components on both sides. A hydraulic cylinder is fixedly installed inside the base, and a hydraulic rod is slidably connected to the inner cavity of the hydraulic cylinder. A first connecting block is fixedly installed at one end of the hydraulic rod. The invention reduces damage to the connection device when it collides with the mobile device, preventing displacement of the equipment during the collision and thus avoiding loosening or shifting of the connection components. The clamping component provides stable clamping of the component, allowing the clamp to conform to the outer surface of the component according to its specifications.

Description

Technical Field

[0001] This application relates to the field of building component construction technology, and in particular to a foldable hinged connection device and assembly method for large components. Background Technology

[0002] In the manufacturing and use of large structural components, such as composite main beams for bridges, grid shell structures, and heavy equipment frames for industrial plants, key components often require segmented manufacturing, followed by on-site assembly into a whole for use. Currently, during on-site installation and assembly, workers mostly use traditional methods, relying on shims to connect adjacent sections, and then strengthening the connection through bolt fixing and welding of hinged edges, thus achieving the splicing of large components. However, the following problems exist:

[0003] 1. Existing connection devices lack stable clamping components. Without stable clamping, prefabricated components are difficult to position accurately during splicing, and are prone to lateral slippage during clamping. This is difficult for workers to detect in time, resulting in misalignment and offset between adjacent prefabricated components. Consequently, the overall structural dimensions after splicing deviate significantly, and the connection between spliced ​​prefabricated components is not firm, affecting project quality and subsequent use. In addition, the clamps are prone to deformation during long-term use, thereby reducing the accuracy of clamping and positioning. The clamping components cannot correct the position when deformation occurs, and it is difficult to detect the deformation of the clamps in time. Multiple adjustments are required, which reduces splicing efficiency.

[0004] 2. The existing connection device does not have a protective mechanism. When other mobile devices come into contact with or collide with the connection device, the connection device is easily damaged. At the same time, the device is displaced, resulting in loosening and displacement of the connection parts. This makes it impossible for the spliced ​​prefabricated parts to meet the design requirements for precision and tightness, which seriously affects the integrity and stability of the structure and creates safety hazards for subsequent projects.

[0016] A foldable hinged connection assembly method for large components, using the aforementioned connection device, includes the following steps:

[0017] S1. The protective component is used to prevent other mobile devices from approaching the base. During the process of contacting the base, the device first contacts the protective component and produces a buffering effect to prevent it from affecting the clamping component.

[0018] S2. Place the components to be spliced ​​on the clamping assembly for clamping and fixing. During the clamping process, it can prevent the components from slipping to the side. At the same time, it can correct the position when the folding mechanism is close, so as to prevent the clamping assembly from being inaccurate when splicing.

[0019] S3. The operation of the hydraulic cylinder drives the first connecting block to move, and the movement of the first connecting block drives the two folding mechanisms to move closer together, thereby assembling the components.

[0020] The technical solution provided in this application has at least the following technical effects or advantages:

[0021] 1. By employing protective components, this invention effectively solves the problem of existing connecting devices lacking protective mechanisms. When other mobile devices come into contact with or collide with the connecting device, the connecting device is easily damaged, causing displacement and resulting in loosening or shifting of the connecting parts. This prevents the assembled prefabricated components from meeting the design requirements for precision and tightness, seriously affecting the integrity and stability of the structure and creating safety hazards for subsequent projects. This invention, through protective components, can reduce the damage to the connecting device when mobile devices collide with it, preventing displacement of the equipment during the collision process and avoiding loosening or shifting of the connecting components. This ensures that the assembled components meet the design requirements, thereby guaranteeing the integrity and stability of the assembled components and improving safety for subsequent projects.

[0022] 2. By employing clamping components, the problem of existing connection devices lacking stable clamping components is effectively solved. The lack of stable clamping components makes it difficult to accurately position prefabricated components during assembly, and slippage is prone to occur during clamping, which is difficult for workers to detect in time. This leads to misalignment and offset between adjacent prefabricated components, resulting in large deviations in the overall structural dimensions after assembly. The connections between the assembled prefabricated components are not secure, affecting project quality and subsequent use. Furthermore, the clamps are prone to deformation during long-term use, reducing the accuracy of clamping and positioning. The clamping components cannot correct the position when deformation occurs and are difficult to address promptly. The discovery of fixture deformation necessitates multiple adjustments, reducing splicing efficiency. This invention addresses this by using a clamping assembly to stably hold components. The clamps can conform to the component's outer surface according to its specifications, providing both rigid and flexible limiting. An alarm is triggered when the component slips or shifts, allowing for timely detection and adjustment by staff. Furthermore, when the clamping assembly deforms, causing component displacement, it automatically corrects the shift without affecting normal splicing, improving splicing efficiency. An alarm also alerts staff to any shifts in the clamp's position, indicating the need for equipment maintenance. Attached Figure Description

Detailed Implementation

[0038] For devices lacking protective mechanisms, this invention reduces damage to the connecting device during collisions with mobile devices and connecting devices through protective components, preventing displacement of the device during collisions that could lead to loosening or displacement of the connecting components. For devices lacking stable clamping components, this invention provides stable clamping of components through clamping components, allowing the clamp to conform to the outer surface of the component according to its specifications. It provides dual limiting of the component through both rigid and flexible limits, and issues an alarm when the component slips or shifts, facilitating timely detection and adjustment by staff.

[0039] 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.

[0040] Example 1:

[0041] Please see Figure 1 and Figure 2 As shown, a foldable hinged connection device for large components includes a base 1, protective components 2 on both sides of the base 1, a hydraulic cylinder 3 fixedly installed in the inner cavity of the base 1, a hydraulic rod slidably connected to the inner cavity of the hydraulic cylinder 3, a first connecting block 4 fixedly installed at one end of the hydraulic rod, the first connecting block 4 slidably connected to the inner cavity of the base 1, a folding mechanism 5 provided on the upper surface of the base 1, two folding mechanisms 5, one of which has a first lifting block 6 slidably connected to its inner wall and is fixedly connected to the base 1, and the other has a second lifting block 7 slidably connected to its inner wall and is also slidably connected to the base 1, with the folding mechanism 5 located above the base 1. A clamping assembly 8 is provided, and a straightening rod 9 is provided on the outer surface of the clamping assembly 8 where the second lifting block 7 is located. A fixing block 10 is fixedly installed on the inner wall of the second lifting block 7. The component is placed on the clamping assembly 8 for clamping and fixing. The hydraulic cylinder 3 drives the hydraulic rod to move, and the movement of the hydraulic rod drives the first connecting block 4 to move in the inner cavity of the base 1. At this time, the folding mechanism 5 connected to the second lifting block 7 moves, while the folding mechanism 5 connected to the first lifting block 6 remains fixed, so that the two folding mechanisms 5 are close together, thereby bringing the two components closer together for splicing. The protective assembly 2 is used to protect the base 1 and prevent other mobile devices from colliding with the base 1 and affecting the splicing of the components.

[0042] Please see Figure 2 and Figure 3 As shown, the protective component 2 includes a protective frame 21, which is slidably connected to the inner cavity of the base 1. A roller 22 is rotatably connected to the inner cavity of the protective frame 21. The protective frame 21 protrudes from the outer side of the base 1. Buffer mechanisms 23 are provided at both ends of the protective frame 21. An alarm mechanism 24 is provided in the inner cavity of the base 1. The roller 22 is used to guide other equipment when it approaches the base 1, reducing the impact on the protective frame 21. When an impact occurs on the protective frame 21, the buffer mechanism 23 can buffer the impact force. The alarm mechanism 24 can sound an alarm when the impact reaches a certain level, while increasing the friction between the equipment and the ground to prevent the equipment from moving and avoid affecting the components.

[0043] Please see Figure 4 , Figure 5 and Figure 6As shown, the buffer mechanism 23 includes a buffer frame 231. A fixing rod 232 is fixedly installed on the outer surface of the buffer frame 231. A first slide block 233 is slidably connected to the outer surface of the fixing rod 232. The first slide block 233 and the buffer frame 231 are slidably connected. A first spring 234 is sleeved in the middle part of the fixing rod 232. The first spring 234 is located between the first slide blocks 233. A first connecting strip 235 is rotatably connected to the inner cavity of the first slide block 233. A buffer plate 236 is rotatably connected to the end of the first connecting strip 235 away from the first slide block 233. The buffer frame 231 is fixedly connected to the inner wall of the base 1. The buffer plate 236 is fixedly connected to the protective frame 21. The alarm mechanism 24 includes an inclined block 241. An anti-slip leg 242 is slidably connected to the bottom end of the inclined block 241. A limiting plate 243 is fixedly installed on the inner wall of the base 1. A connecting rod 244 is fixedly installed on the upper surface of the limiting plate 243. A first sliding rod 245 is fixedly installed in the inner cavity of the anti-slip leg 242. A second spring 246 is sleeved on the outer surface of the first sliding rod 245. The first sliding rod 245 and the limiting plate 243 are slidably connected. The anti-slip leg 242 and the inner cavity of the base 1 are slidably connected. The second spring 246 is located between the inclined block 241 and the limiting plate 243. A first button 247 is provided on the bottom wall of the inclined block 241. A first alarm 248 is fixedly installed on the outer surface of the inclined block 241. The first button 247 and the first alarm 248 are electrically connected. Pressing the first button 247 controls the first alarm 248 to sound an alarm. The first button 247 and the connecting rod... Alignment 244, a compression rod 249 is fixedly installed on the outer surface of the protective frame 21. The compression rod 249 and the inclined block 241 are at the same height, and there is a gap between the inclined block 241 and the compression rod 249. The bottom end of the anti-slip leg 242 is housed in the inner cavity of the base 1. The bottom end of the anti-slip leg 242 has a groove. When the protective frame 21 is impacted, the protective frame 21 compresses the buffer plate 236, causing the first connecting bar 235 to rotate. The rotation of the first connecting bar 235 causes the first connecting bar 235 to rotate in the inner cavity of the first slide 233 and compress the first spring 234. At this time, the elastic force of the first spring 234 can buffer the impact on the protective frame 21, thereby reducing the impact on the base 1 during the impact. At the same time, when the protective frame 21 moves, it drives the compression rod 249. When the impact force is large, the compression rod 249 contacts the inclined block 241 and compresses it. At this time, the anti-slip leg 242 slides down the inner cavity of the base 1. The downward movement of the anti-slip leg 242 causes the first sliding rod 245 to move down. The downward movement of the first sliding rod 245 causes the limiting plate 243 to compress the second spring 246. At this time, the connecting rod 244 compresses the first alarm 248 and sounds an alarm, reminding the staff that the protective frame 21 has been impacted. It is necessary to observe the splicing of the components and whether the equipment has been displaced or damaged, and to carry out maintenance and adjustment in a timely manner. At the same time, when the anti-slip leg 242 moves down, it contacts the ground and has a compressing effect, thereby increasing the friction between the base 1 and the ground, thus enhancing the grip of the equipment.To prevent equipment displacement during impact, thereby ensuring stability during impact and guaranteeing the stability of component assembly.

[0044] Please see Figure 1 and Figure 7 As shown, the folding mechanism 5 includes a support base 51. A first threaded rod 52 is rotatably connected to the inner cavity of the support base 51. First moving blocks 53 are threadedly connected to both ends of the first threaded rod 52, with the threads at both ends of the first threaded rod 52 being opposite. Second connecting strips 54 are rotatably connected to both ends of the first moving blocks 53. A first motor 55 is mounted on the outer surface of the support base 51. The output end of the first motor 55 is sleeved with the first threaded rod 52. A folding plate 56 is slidably connected to the inner cavity of the support base 51. The folding plate 56 serves to protect the first threaded rod 52, and slides within the inner cavity of the support base 51 to block the folding plate 56. The folding plate 56... The first lifting block 6 and the second lifting block 7 are fixedly connected. The end of the second connecting bar 54 away from the first moving block 53 is rotatably connected to the second connecting block 57. The second connecting block 57 is fixedly connected to the first lifting block 6 and the second lifting block 7 respectively. The operation of the first motor 55 drives the first threaded rod 52 to rotate. The rotation of the first threaded rod 52 drives the first moving block 53 to move on the first threaded rod 52, causing the angle of the second connecting bar 54 to deflect. This causes the height of the second connecting block 57 to change, which in turn causes the height of the clamping assembly 8 to change. The height of the clamping assembly 8 can be adjusted according to the specifications of the component to achieve the effect of folding and storage.

[0045] Example 2:

[0046] Please see Figure 1 and Figure 8 As shown, the clamping assembly 8 includes a support platform 81, with clamping mechanisms 82 slidably connected to both ends of the support platform 81. A third threaded rod 83 is rotatably connected to the inner cavity of the support platform 81. A second motor 84 is provided on the outer surface of the support platform 81, and the output end of the second motor 84 is sleeved with the third threaded rod 83. A straightening mechanism 85 is provided on the outer surface of the first lifting block 6. There are two support platforms 81, clamping mechanisms 82, third threaded rods 83, and second motors 84. There is only one straightening mechanism 85, which is fixedly connected to the first lifting block 6. The support platform 81 in the inner cavity of the second lifting block 7 is fixedly connected to the second lifting block 7. The support platform 81 in the inner cavity of the first lifting block 6 is slidably connected to the first lifting block 6. The operation of the second motor 84 drives the third threaded rod 83 to rotate. The rotation of the third threaded rod 83 drives the clamping mechanism 82 to move on the support platform 81, so that the clamping mechanism 82 clamps and fixes the component. Thus, the component is brought closer together by the folding mechanism 5 of the second lifting block 7 and then spliced.

[0047] Please see Figure 9 and Figure 10As shown, the clamping mechanism 82 includes a movable plate 821. A flexible connecting mechanism 822 is fixedly installed in the inner cavity of the movable plate 821. One end of the flexible connecting mechanism 822 is fixedly connected to a limiting mechanism 823. An adjusting mechanism 824 is provided on the outer surface of the limiting mechanism 823. The movable plate 821 and the support platform 81 are slidably connected, and the movable plate 821 and the third threaded rod 83 are connected by threads. The threads at both ends of the third threaded rod 83 are in opposite directions. The movable plate 821 is symmetrically distributed about the middle part of the support platform 81. The sexual connection mechanism 822 includes a connecting seat 8221, a second slide 8222 slidably connected to the inner cavity of the connecting seat 8221, a third spring 8223 disposed at one end of the second slide 8222, the third spring 8223 being located between the inner wall of the connecting seat 8221 and the second slide 8222, a pressure ring 8224 rotatably connected to the end of the second slide 8222 away from the third spring 8223, and a floating block 8225 rotatably connected to the inner cavity of the connecting seat 8221, the pressure ring 8224 and the floating block 8225 being tightly connected. The floating blocks 8225 are symmetrically distributed about the pressure ring 8224. The inner walls of the connecting seat 8221 and the moving plate 821 are fixedly connected. When the component is clamped, the third threaded rod 83 rotates, causing the moving plate 821 to move closer to each other. At this time, the limiting mechanism 823 clamps and fixes the component. The flexible connecting mechanism 822 can be angled according to the specifications of the component, so that the limiting mechanism 823 can fit against the outer surface of the component to improve the stability of the component. When the component slides, the adjusting mechanism 824 will sound an alarm to remind the staff to maintain it in time. When the outer surface of the component is tilted, the limiting mechanism 823 will cause the angle of the floating block 8225 to deflect when clamping. At this time, the floating block 8225 squeezes the pressure ring 8224, causing the second slide 8222 to slide in the inner cavity of the connecting seat 8221 and squeeze the third spring 8223. At this time, the angle of the floating block 8225 deflects, so that the limiting mechanism 823 can fit against the outer surface of the component, improving the stability of clamping the component and facilitating the subsequent splicing of components.

[0048] Please see Figure 11 and Figure 12As shown, the limiting mechanism 823 includes a clamping block 8231, which is fixedly connected to a floating block 8225. Sliding grooves 8232 are formed at both ends of the clamping block 8231. A limiting block 8233 is slidably connected to the inner cavity of the clamping block 8231. Second sliding rods 8234 are fixedly installed at both ends of the limiting block 8233. A fourth spring 8235 is sleeved on the outer surface of the second sliding rod 8234, located between the inner walls of the limiting block 8233 and the clamping block 8231. The second sliding rod 8234 and the sliding groove 8232 are slidably connected, meaning the second sliding rod 8234 can slide laterally and longitudinally within the inner cavity of the sliding groove 8232. A slider 8236 is slidably connected to the inner wall of the clamping block 8231. Insert rods 8237 are fixedly installed at both ends of the slider 8236. The rod 8237 and the limiting block 8233 are slidably connected. A fifth spring 8238 is provided in the middle of the slider 8236. The fifth spring 8238 is used to compress the limiting block 8233, so that the limiting block 8233 and the component are in close contact. The limiting block 8233, together with the clamping block 8231, achieves double limiting of the component, that is, the clamping block 8231 provides rigid limiting, and the limiting block 8233 provides flexible connection. The fifth spring 8238 is located between the slider 8236 and the limiting block 8233. A first pressing block 8239 is fixedly installed on the outer surface of the limiting block 8233. The limiting block 8233 protrudes from the outside of the clamping block 8231. The adjusting mechanism 824 includes a second threaded rod 8241, which is rotatably connected to the clamping block 8231. The two ends of the second threaded rod 8241 are threadedly connected to the second moving blocks 8242, and the threads at the two ends of the second threaded rod 8241 are in opposite directions. A second button 8243 is provided on the outer surface of the second moving block 8242, and a second alarm 8244 is fixedly installed on the outer surface of the second moving block 8242. The second button 8243 and the second alarm 8244 are electrically connected, and pressing the second button 8243 controls the second alarm 8244 to sound an alarm. The second moving block 8242 and the inner wall of the clamping block 8231 are slidably connected. The distance from the first pressing block 8239 to the second buttons 8243 on both sides is equal, and the height of the first pressing block 8239 and the second button 8243 is flush. When clamping the component, the limiting block 8233 first contacts the component. As the clamping force increases, the clamping block 8231 and the limiting block 8233 become flush. At this point, the slider 8236 and the limiting block 8233 approach each other and compress the fifth spring 8238. Simultaneously, the insertion rod 8237 slides within the cavity of the limiting block 8233. The limiting block 8233 and the clamping block 8231 together continue to limit the component, and the limiting block 8233 provides flexible limitation. When the component shifts, it causes the limiting block 8233 to slide within the cavity of the slide groove 8232. The movement of the limiting block 8233 causes the slider 8236 to slide within the inner wall of the clamping block 8231. At this time, the second sliding rod 8234 slides within the cavity of the slide groove 8232 and compresses the fourth spring 8235. The movement of the limiting block 8233 causes the first compression block 8239 to move.The movement of the first pressing block 8239 presses the second button 8243, at which point the second alarm 8244 sounds an alarm, alerting the operator that the component has slipped or shifted on the clamp. By rotating the second threaded rod 8241, the second moving block 8242 slides within the cavity of the clamping block 8231, adjusting the gap between the second button 8243 and the first pressing block 8239, thereby setting the component's slippage alarm value for easy adjustment as needed.

[0049] Please see Figure 2 , Figure 13 and Figure 14As shown, the correction mechanism 85 includes a correction block 851. Third slide rods 852 are fixedly installed at both ends of the correction block 851. A sixth spring 853 is sleeved on the outer surface of the third slide rods 852. A positioning groove 854 is provided on one side of the correction block 851. A correction sleeve 855 is provided above the correction block 851. The correction sleeve 855 is fixedly connected to the support platform 81. A connecting frame 856 is fixedly installed on the outer surface of the first lifting block 6. A third alarm 857 is fixedly installed on the lower surface of the connecting frame 856. The third alarm 857, the first alarm 248, and the second alarm 8244 use different alarm sounds to easily distinguish the location of the problem, enabling staff to quickly troubleshoot and perform rapid maintenance. The inner cavity of the connecting frame 856 slides... A positioning rod 858 is connected, with a positioning ball 859 movably connected to one end of the positioning rod 858. A third button 8510 is provided on the outer surface of the connecting frame 856. A second pressing block 8511 is fixedly installed on the outer surface of the positioning rod 858, and the second pressing block 8511 is slidably connected to the connecting frame 856. A seventh spring 8512 is sleeved on the end of the positioning rod 858 away from the positioning ball 859. The seventh spring 8512 is located between the inner wall of the connecting frame 856 and the second pressing block 8511. The third button 8510 is electrically connected to a third alarm 857, and pressing the third button 8510 controls the third alarm 857 to sound an alarm. The positioning ball 859 engages with the positioning groove 854, so that the positioning ball 859 limits the position of the correction block 851. When the support platform 81 remains stable, the straightening block 851 remains stable. When the support platform 81 shifts, the insertion of the straightening rod 9 and the straightening sleeve 855 corrects the position of the support platform 81, achieving precise splicing of the components. The straightening block 851 and the first lifting block 6 are slidably connected. The inner cavity of the straightening sleeve 855 is aligned with the straightening rod 9, and the end of the straightening sleeve 855 away from the support platform 81 is chamfered. By moving the folding mechanism 5 where the second lifting block 7 is located, the two folding mechanisms 5 are brought closer, thereby allowing the components to contact and splice. If the support platform 81 shifts slightly during prolonged use, when the second lifting block 7 approaches the first lifting block 6, it causes the straightening rod 9 to press against the chamfer of the straightening sleeve 855, causing the straightening rod 9 to insert into the straightening sleeve. Inside the cavity of 855, the straightening sleeve 855 undergoes a certain displacement, causing the support platform 81 to move. The movement of the support platform 81 causes the straightening block 851 to move. The movement of the straightening block 851 causes the third slide rod 852 to slide within the cavity of the first lifting block 6 and compress the sixth spring 853. At this time, the positioning groove 854 and the positioning ball 859 disengage, causing the positioning ball 859 to contact the outer surface of the straightening block 851. This causes the positioning rod 858 to slide within the cavity of the connecting frame 856. The sliding of the positioning rod 858 causes the second pressing block 8511 to slide within the cavity of the connecting frame 856 and compress the seventh spring 8512. Simultaneously, the second pressing block 8511 compresses the third button 8510, causing the third alarm 857 to sound an alarm.The system alerts staff that the support platform 81 has shifted, requiring equipment maintenance. Simultaneously, when the straightening rod 9 and straightening sleeve 855 engage, the support platform 81 can move to align itself, achieving automatic correction without affecting the normal assembly of components, thus improving assembly efficiency. When the support platform 81 is not shifted, the straightening sleeve 855 and straightening rod 9 engage normally without any squeezing effect. In this case, the positioning ball 859 and positioning groove 854 remain engaged, ensuring component alignment and precise assembly.

[0050] In summary, the operation of hydraulic cylinder 3 drives the hydraulic rod to move, which in turn moves the first connecting block 4 within the cavity of base 1. At this time, the folding mechanism 5 connected to the second lifting block 7 moves, while the folding mechanism 5 connected to the first lifting block 6 remains fixed, bringing the two folding mechanisms 5 closer together. This allows the two components to be joined together. The protective component 2 protects base 1 from collisions with other mobile devices that could affect the joining of components. When the protective frame 21 is impacted, the buffer mechanism 23 can buffer the impact force. The alarm mechanism 24 can sound an alarm when the impact reaches a certain level, while also increasing the friction between the equipment and the ground to prevent the equipment from moving and thus avoid affecting the components. The operation of the second motor 84 drives the third threaded rod 83 to rotate, which in turn moves the clamping mechanism 82 on the support platform 81, clamping and fixing the components. Thus, by moving the folding mechanism 5 of the second lifting block 7, the components are brought closer together and joined together.
