Description

Technical Field

[0001] This invention belongs to the technical field of cantilever components, specifically relating to a combined roof cantilever component. Background Technology

[0002] Roof cantilever beams are widely used in canopies, eaves, and other parts of buildings such as stadiums, theaters, and train stations. To ensure the safety and stability of the cantilever structure, tie rods are usually installed at specific locations on the cantilever beam. The most common practice is to weld lugs onto the cantilever beam and connect the lugs to the upper connection points of the main structure using steel tie rods or cables, thus forming a stable triangular load-bearing system.

[0003] In actual use, since cantilever beam components are usually large in size, the space is compact when transporting and stacking them. The lifting lugs welded to them become the most prominent parts, which are very easy to collide with transport vehicles, stacking supports or other components. Such collisions can cause the lifting lugs to bend and deform, thus affecting the subsequent installation of tie rods. Summary of the Invention

The rotation of the rotating plate facilitates the movement of the insert plate, thereby facilitating the positioning of the slider, preventing the slider from shifting, and making it easier to install the pull rod later.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0020] Reference Figures 1-8 This is the first embodiment of the present invention. This embodiment provides a combined roof cantilever component, including a storage component, including a cantilever beam 10. A storage shell 11 is fixedly connected to the top of the cantilever beam 10. A rubber pad 12 is fixedly connected to the outside of the storage shell 11. A support column 13 is fixedly connected to the inner wall of the storage shell 11. Two support columns 13 are provided and symmetrically arranged on the inner wall of the storage shell 11. A slider 14 is slidably connected to the outside of the support column 13. A lifting lug 15 is fixedly connected to the top of the slider 14. The lifting lug 15 can be stored inside the storage shell 11 by moving and rotating. A limiting component 16 for constraining the lifting lug 15 is provided on the inner wall of the storage shell 11. A rotating component 17 is provided inside the storage shell 11. A lifting component 18 is provided on the inner wall of the storage shell 11.

[0021] The storage shell 11 serves as a protective structure, providing a space for the lifting lug 15. The rubber pad 12 on its exterior acts as a buffer against impacts. The support column 13 provides precise guidance for the linear movement of the slider 14. The limiting component 16, the rotating component 17, and the lifting component 18 work together to achieve the constraint, release, and ejection functions of the lifting lug 15. When the lifting lug 15 is needed, the operation of the rotating component 17 sequentially triggers the limit release and lifting action, exposing part of the lifting lug 15 for easy access. After being moved to a vertical position, the positioning component 22 automatically locks it in the working state, facilitating the subsequent installation of the pull rod.

[0022] The top of the storage shell 11 is provided with a through groove corresponding to the position of the hanging lug 15, and the hanging lug 15 is slidably connected in the through groove. The through groove is L-shaped, which makes it easy to limit the hanging lug 15 in the vertical state so that the hanging lug 15 cannot rotate. When the slider 14 contacts the inner wall of the storage shell 11, the through groove allows the hanging lug 15 to rotate, which facilitates the storage of the hanging lug 15.

[0023] Furthermore, the limiting component 16 includes a surrounding frame 161 fixedly connected to the inner wall of the storage shell 11. A support plate 162 is slidably connected inside the surrounding frame 161. A locking plate 163 is fixedly connected to the top of the support plate 162. A square plate 164 is fixedly connected to one end of the support plate 162 near the surrounding frame 161. An extension block 165 is fixedly connected to the bottom of the square plate 164. A first guide rod 166 is fixedly connected to the inner wall of the surrounding frame 161. The inner side of the extension block 165 is connected to the surrounding frame 161 by a first spring 167. 61. An L-shaped plate 168 is fixedly connected to the inner side of the square plate 164. When the lug 15 is pushed into the storage position, it will squeeze the locking plate 163 to retract it. After it is in place, the locking plate 163 is reset under the push of the first spring 167 and locks into the groove on the side of the lug 15 to achieve a limit, thereby preventing the lug 15 from rotating and ensuring the stability of the lug 15. When unlocking, the L-shaped plate 168 drives the entire support plate 162 to move, so that the locking plate 163 is disengaged from the lug 15. After the lug 15 is lifted, it can rotate and move.

[0024] The extension block 165 has a through hole at the position corresponding to the first guide rod 166, and the first guide rod 166 is slidably connected in the through hole. This ensures that the extension block 165, together with the square plate 164 and the support plate 162, can only slide smoothly along the axial direction of the first guide rod 166, avoiding jamming during the movement and ensuring the reliability and accuracy of the action of the limiting component 16.

[0025] Furthermore, the rotating assembly 17 includes a rotating shaft 171 rotatably connected inside the housing 11. A rotating wheel 172 is fixedly connected to the top of the rotating shaft 171. The rotating wheel 172 is hexagonal, and the top of the rotating plate 173 has an internal hexagonal groove, which facilitates the operator to use tools to rotate the rotating wheel 172. A rotating plate 173 is fixedly connected to the bottom of the rotating shaft 171. A pushing rod 174 is fixedly connected to the bottom of the rotating plate 173. The pushing rod 174 contacts the L-shaped plate 168. When the operator uses tools to rotate the rotating wheel 172, it drives the rotating shaft 171 and the rotating plate 173 to rotate. The pushing rod 174 on the rotating plate 173 rotates accordingly and pushes the L-shaped plate 168 to move. This not only facilitates the release of the limiting work on the lifting lug 15, but also facilitates the subsequent lifting work on the lifting lug 15.

[0026] Furthermore, the lifting assembly 18 includes a trapezoidal block 181 fixedly connected to the inner wall of the bottom of the storage shell 11. A lifting rod 182 is slidably connected inside the support plate 162. A roller 183 is rotatably connected to the bottom of the lifting rod 182. A semi-circular block 184 is fixedly connected to the top of the lifting rod 182. When the support plate 162 is pushed and moved by the rotating assembly 17, it drives the lifting rod 182 and the roller 183 at its bottom to move together. The roller 183 rolls along the inclined surface of the trapezoidal block 181, forcing the lifting rod 182 to slide upward inside the support plate 162. The semi-circular block 184 at the top rises and lifts the lifting lug 15. After the semi-circular block 184 moves to its maximum height, the lifting lug 15, which is lifted and rotated, will extend out of the through slot opened at the top of the storage shell 11 to ensure that the operator can manually rotate and move the lifting lug 15.

[0027] The support plate 162 has a groove at the position corresponding to the semicircular block 184, and the semicircular block 184 is slidably connected in the groove. This groove provides a vertical movement track for the semicircular block 184, and the groove structure also houses the semicircular block 184 inside the support plate 162, ensuring that the lifting lug 15 and the support plate 162 fit together stably.

[0028] When transporting or stacking the cantilever beam 10, the lifting lug 15 must first be adjusted to the retracted position. The operator pushes the lifting lug 15 horizontally along the L-shaped through-slot at the top of the storage shell 11, causing the slider 14 at its bottom to slide along the support column 13 towards the inner wall of the storage shell 11. When the slider 14 contacts the inner wall of the storage shell 11, the lifting lug 15 moves from the vertical section of the through-slot to the horizontal section entrance, at which point the rotation constraint of the lifting lug 15 is released. Subsequently, the operator rotates the lifting lug 15 ninety degrees to flatten it and place it inside the storage shell 11. During this rotation and retraction process, the side of the lifting lug 15 will press against the locking plate 163 of the limiting component 16. The locking plate 163, under force, causes the support plate 162 to slide within the surrounding frame 161, and forces the square plate 164 and the extension block 165 to move along the first guide rod 166, compressing the first spring 167. When the lug 15 is fully retracted and contacts the top of the support plate 162, the extension block 165 is pushed back to its original position by the restoring force of the first spring 167, thereby causing the locking plate 163 to return to its original position. This completes the limiting of the lug 15 in the retracted state, effectively preventing it from rotating accidentally due to vibration during transportation. When the lug 15 needs to be removed for installation, the operator uses a tool to rotate the rotating wheel 172. The rotating wheel 172 drives the rotating shaft 171 and the rotating plate 173 fixed at its lower end to rotate together. The pushing rod 174 at the bottom of the rotating plate 173 pushes the L-shaped plate 168 as it rotates. The L-shaped plate 168 drives the square plate 164, the support plate 162, and the entire limiting assembly 16 to move linearly against the force of the first spring 167, causing the locking plate 163 to move away from the lug 15 and releasing the limiting. As the support plate 162 continues to move, the lifting assembly 18 inside is triggered. The roller 183 at the bottom of the lifting rod 182 begins to contact and roll with the inclined surface of the trapezoidal block 181 fixed to the inner wall of the bottom of the storage shell 11. The inclined surface forces the lifting rod 182 to slide vertically upward within the support plate 162, thereby pushing the semicircular block 184 at its top to rise. After the semicircular block 184 contacts the bottom of the lifting lug 15, it lifts it up and makes it rotate around the support point. This angle ensures that part of the lifting lug 15 is exposed outside the storage shell 11, providing a good hand grip position for the operator, which facilitates the subsequent rotation and movement of the lifting lug 15. The lifting lug 15 is rotated completely ninety degrees to a vertical position, and then moved along the vertical section of the through groove to the working position for subsequent tie rod installation work. Example 2

[0029] Reference Figures 9-11 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a stabilizing component, which includes a U-shaped pad 20 fixedly connected to the inner wall of the top of the storage shell 11. The inner side of the U-shaped pad 20 is fixedly connected to the shell 21, and the interior of the shell 21 is provided with a positioning component 22 for limiting the slider 14.

[0030] Specifically, the U-shaped pad 20 and the housing 21 provide an installation base for the positioning component 22. With the cooperation of the U-shaped pad 20, it is easy to fill the gap between the slider 14 and the storage housing 11, and to distribute the tension on the support column 13 to the storage housing 11.

[0031] Furthermore, the positioning component 22 includes an insert plate 221 slidably connected inside the housing 21. The insert plate 221 is slidably connected to the U-shaped pad 20. An extension plate 222 is fixedly connected to the bottom of the insert plate 221. A second guide rod 223 is fixedly connected to the inner wall of the housing 21. The extension plate 222 is slidably connected to the outside of the second guide rod 223. The outer side of the extension plate 222 is elastically connected to the housing 21 via a second spring 224. A triangular block 225 is fixedly connected to the inner wall of the insert plate 221. A compression wheel 226 is provided outside the triangular block 225. An L-shaped pull plate 227 is rotatably connected to the outside of the compression wheel 226. The pull plate 227 is slidably connected to the housing 21. The L-shaped pull plate 227 contacts the rotating plate 173. The external of the insert plate 221 is fixedly connected to the limit rod 228. The L-shaped pull plate 227 is slidably connected to the outside of the limit rod 228. When the rotating plate 173 rotates to a specific angle, it will squeeze the L-shaped pull plate 227, causing it to drive the squeezing wheel 226 to squeeze the inclined surface of the triangular block 225, forcing the insert plate 221 to overcome the tension of the second spring 224 and retract. When the lifting lug 15 is in place and the rotating plate 173 is released, the second spring 224 pushes the extension plate 222 and the insert plate 221 to pop out along the second guide rod 223, which facilitates the limiting work of the lifting lug 15.

[0032] The lug 15 has a groove at the corresponding position of the insert plate 221, and the insert plate 221 is inserted into the groove. When the insert plate 221 is inserted into the groove, it can effectively prevent the lug 15 and its slider 14 from moving, ensuring the absolute stability of the working state and facilitating the subsequent installation of the pull rod.

[0033] The insert plate 221 has a through groove at the position corresponding to the L-shaped pull plate 227, and the L-shaped pull plate 227 is slidably connected in the through groove. This through groove facilitates the movement of the insert plate 221, thereby avoiding interference between the insert plate 221 and the L-shaped pull plate 227 during the movement.

[0034] In use, rotating the rotating wheel 172 causes the rotating plate 173 to rotate away from the L-shaped plate 168. When the rotating plate 173 contacts and presses the L-shaped pull plate 227, the L-shaped pull plate 227, which slides outside the limiting rod 228, moves. The L-shaped pull plate 227 drives the pressing wheel 226 at its end to move synchronously. The pressing wheel 226 then presses the inclined surface of the triangular block 225 fixed on the insert plate 221. The inclined surface converts the pushing force of the L-shaped pull plate 227 into the pulling force of the insert plate 221, forcing the insert plate 221 to overcome the elastic force of the second spring 224 and slide downward in the guide groove of the U-shaped pad 20 and the housing 21. The extension plate 222 connected to the bottom of the insert plate 221 moves along the second guide rod 223 and stretches the second spring 224. The displacement of the insert plate 221 causes it to exit the predetermined movement path of the lifting lug 15, removing the obstruction to the movement of the lifting lug 15. At this point, the operator can smoothly move the lifting lug 15 to the working position. Once the lifting lug 15 is in place, the groove inside it aligns perfectly with the retracted insert plate 221. The operator releases the rotating wheel 172 or rotates it back to its initial position, and the squeezing force of the rotating plate 173 on the L-shaped pull plate 227 disappears. At this time, the stretched second spring 224 releases its elastic potential energy, pushing the extension plate 222 to reset along the second guide rod 223, thereby driving the positioning assembly 22 to return to its original position and precisely insert it into the groove of the lifting lug 15, preventing the lifting lug 15 from sliding or rotating during operation and ensuring the accuracy and stability of the force point. Furthermore, when the lifting lug 15 is in the working state, there is a gap between the slider 14 and the inner wall of the storage shell 11, which is precisely filled by the U-shaped pad 20 fixed to the storage shell 11. When the tie rod is connected to the lug 15 and bears the tension, the force is transmitted to the slider 14 through the lug 15. Then, through the close contact between the slider 14 and the U-shaped pad 20, a part of the force is directly distributed to the sturdy storage shell 11 body, which enhances the rigidity and safety of the entire cantilever component connection node.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
