Description

Technical Field

[0001] This utility model relates to the field of industrial building technology, and in particular to a roof cover assembly. Background Technology

[0002] Wastewater treatment plants and other industrial facilities typically house large equipment and tanks. Due to the size and weight of this equipment, it's often impossible to transport the tanks out of the main gate using forklifts or other transport equipment during replacement. Therefore, a hoisting opening is installed on the roof, allowing a crane to lift the large equipment and tanks out when replacement is needed. To prevent rainwater from entering the plant during daily operation, the hoisting opening must be covered with a cover to keep it closed.

[0003] The cover is opened only when the tank needs to be replaced. The connection between the cover and the roof is crucial; common methods include sliding rail and flip-top designs. However, sliding rail covers require high-quality materials. The rails, exposed to wind and rain on the roof, will rust over time. Industrial plants typically have infrequent maintenance cycles, opening only once every 10 years. By then, the rails will be corroded, making the cover difficult to open and close. Furthermore, fully opening the access hatch requires an area equal to the hatch's size to install the sliding rails, which is very space-consuming. Flip-top covers are only suitable for small access hatches. Large access hatch covers are too large, weighing several tons, and the hinges on one side cannot support this weight, making them difficult to open and close. In addition, in traditional methods, the connector and cover are usually integrated. If the connector malfunctions, it will affect the cover, requiring replacement of the cover or removal and replacement of the connector, which is costly, labor-intensive, and time-consuming. Utility Model Content

[0005] This utility model provides the following technical solution:

[0006] A roof cover assembly for covering and sealing roof hoisting openings, the roof cover assembly including a cover plate and a telescopic component.

[0007] The cover plate has multiple first connecting seats evenly distributed on its side, and the outer periphery of the lifting port has a second connecting seat corresponding to the first connecting seat; the telescopic assembly includes a connector, a first connecting rod, and a second connecting rod, the first connecting rod and the second connecting rod being operatively connected to the connector, and the telescopic assembly being able to drive the first connecting rod and the second connecting rod to telescopically move relative to the connector; the first connecting rod has a first connecting part corresponding to the first connecting seat, and the first connecting part is assembled and connected to the first connecting seat; the second connecting rod has a second connecting part corresponding to the first connecting seat, and the second connecting part is assembled and connected to the second connecting seat.

[0008] As a further improvement to the above technical solution, the first connecting rod and the second connecting rod are respectively threaded onto the connecting member.

[0009] As a further improvement to the above technical solution, the threads of the first connecting rod and the second connecting rod are rotated in opposite directions.

[0010] As a further improvement to the above technical solution, both the first connecting rod and the second connecting rod are fitted with elastic dust covers. The end of the dust cover away from the connecting member is fixedly connected to the first connecting rod or the second connecting rod, and the end of the dust cover near the connecting member abuts against the connecting member.

[0011] As a further improvement to the above technical solution, both the first connecting part and the second connecting part are hooks, and the opposite end faces of the first connecting seat and the second connecting seat are provided with hanging grooves, and the hooks are engaged with the corresponding hanging grooves.

[0012] As a further improvement to the above technical solution, a sealing boss is provided on the end face of the lifting port near the cover plate, and a sealing groove corresponding to the sealing boss is provided on the end face of the cover plate near the lifting port, and the sealing boss is installed in the sealing groove.

[0013] As a further improvement to the above technical solution, a sealing gasket is provided between the sealing boss and the sealing groove.

[0014] As a further improvement to the above technical solution, a drainage slope is provided on the side of the end face of the lifting port near the cover plate facing the outer wall, and the height of the drainage slope near the outer wall of the lifting port is lower than the height of the inner wall of the lifting port.

[0015] As a further improvement to the above technical solution, the end face of the cover plate facing away from the lifting port is an arc-shaped surface that protrudes away from the lifting port.

[0016] As a further improvement to the above technical solution, a protective pad is laid on the end face of the cover plate away from the hoisting port.

[0017] As a further improvement to the above technical solution, the protective pad extends away from the center of the cover plate and covers the telescopic component.

[0018] Compared with related technologies, the beneficial effects of this utility model are:

[0019] In practical applications, when it is necessary to cover the hoisting opening of a factory building, the roof cover assembly provided by this utility model first needs to be moved to the position directly above the hoisting opening by means of hoisting equipment or manual hoisting. After the cover reaches the hoisting opening, it is then pressed onto the hoisting opening.

[0020] After the initial placement of the cover plate, the operator needs to connect the first and second connecting rods to the pre-installed first connecting seats on the cover plate and the second connecting seats on the outer wall of the lifting port, respectively. After connection, the operator must sequentially control the corresponding first and second connecting rods to extend and retract relative to the telescopic components of the telescopic assembly. By controlling the extension and retraction length of the telescopic rods, the first and second connecting seats are gradually tightened, making the connection between the cover plate and the lifting port tighter and more stable. During the tightening process, it is necessary to monitor the tightening of each telescopic component to ensure that the tension force in all directions is uniform and consistent, avoiding uneven local stress. Once all telescopic components have been tightened, the entire process of installing the cover plate on the lifting port is complete.

[0021] When it's necessary to open the lifting port, operators simply need to reverse the installation process described above. First, loosen all the telescopic components to gradually reduce the tension between the first connecting rod, the second connecting rod, and the first and second connecting seats. Then, sequentially disconnect the connections between the first connecting rod and the first connecting seat, and the second connecting rod and the second connecting seat. Finally, remove the cover plate from the lifting port using hoisting equipment or manually. The entire operation is simple and easy to understand; operators can master it with minimal training. Furthermore, the operation is relatively safe, effectively preventing accidents caused by improper operation. At the same time, this connection structure has a significant advantage in terms of space utilization, minimizing the space occupied around the lifting port and facilitating normal factory production and operation.

[0022] Furthermore, during the aforementioned usage, the weight of the entire cover plate is primarily borne by the hoisting equipment during the hoisting process, or, once the cover plate is placed on the hoisting opening, its weight is mainly supported by the side wall of the hoisting opening. The telescopic component only needs to provide tension throughout the entire process and does not need to bear the weight of the cover plate. This design effectively reduces the stress on the telescopic component, decreasing the probability of damage due to excessive weight, thereby ensuring the reliability of the roof cover plate assembly of this invention and extending its service life.

[0023] Furthermore, since the telescopic components are all connected to the lifting ports and cover plates in a movable manner, this connection method greatly facilitates later maintenance and replacement work. When a telescopic component malfunctions, operators can disassemble and replace the faulty component individually without having to disassemble and reinstall the entire roof cover plate assembly on a large scale. This not only effectively reduces maintenance costs and downtime caused by equipment repairs, but also improves maintenance efficiency, ensuring that normal factory production is not affected.

[0036] like Figure 1 As shown, an embodiment of the present invention provides a roof cover assembly for covering and sealing the roof hoisting opening 200. The roof cover assembly includes a cover plate 100 and a telescopic component 300.

[0037] The cover plate 100 is provided with a plurality of first connecting seats 110 evenly distributed on its side, and the outer periphery of the hoisting port 200 is provided with a second connecting seat 210 corresponding to the first connecting seat 110; the telescopic component 300 includes a connector 310, a first connecting rod 320, and a second connecting rod 330, the first connecting rod 320 and the second connecting rod 330 being operatively connected to the connector 310 respectively, and the telescopic component 300 being able to drive the first connecting rod 320 and the second connecting rod 330 to telescopically move relative to the connector 310 respectively; the first connecting rod 320 is provided with a first connecting part 321 corresponding to the first connecting seat 110, and the first connecting part 321 is assembled and connected to the first connecting seat 110; the second connecting rod 330 is provided with a second connecting part 331 corresponding to the first connecting seat 110, and the second connecting part 331 is assembled and connected to the second connecting seat 210.

[0038] In practical applications, when it is necessary to cover the hoisting opening 200 of a factory building, the roof cover assembly provided in this embodiment first needs to be moved to a position directly above the hoisting opening 200 by means of hoisting equipment or manual hoisting. After the cover 100 reaches the hoisting opening 200, it is then placed on the hoisting opening 200.

[0039] After the initial placement of the cover plate 100, the operator needs to connect the first connecting rods 320 and the second connecting rods 330 to the pre-set first connecting seat 110 on the cover plate 100 and the second connecting seat 210 on the outer wall of the lifting port 200, respectively. After the connection is completed, the operator needs to control the corresponding first connecting rods 320 and second connecting rods 330 to move back and forth relative to the telescopic components of the telescopic assembly 300. By controlling the extension and retraction length of the telescopic rods, the first connecting seat 110 and the second connecting seat 210 are gradually tightened, making the connection between the cover plate 100 and the lifting port 200 tighter and more stable. During the tightening process, it is necessary to pay attention to the tightening status of each telescopic assembly 300 to ensure that the tightening force in all directions is uniform and consistent, avoiding uneven local stress. After all the telescopic assemblies 300 have been tightened, the entire process of installing the cover plate 100 on the lifting port 200 is complete.

[0040] When it is necessary to open the lifting port 200, the operator only needs to follow the reverse steps of the installation process described above. First, loosen each telescopic component 300 to gradually reduce the tension between the first connecting rod 320, the second connecting rod 330 and the first connecting seat 110, and the second connecting seat 210. Then, sequentially dismantle the connections between the first connecting rod 320 and the first connecting seat 110, and the second connecting rod 330 and the second connecting seat 210. Finally, remove the cover plate 100 from the lifting port 200 using hoisting equipment or manual lifting. The entire operation process is simple and easy to understand. Operators can master it after only simple training. Moreover, the operation process is relatively safe and can effectively avoid safety accidents caused by improper operation. At the same time, this connection structure has a significant advantage in terms of space occupation, as it does not occupy too much space around the lifting port 200, providing convenience for the normal production and operation of the factory.

[0041] Furthermore, during the aforementioned usage, the weight of the entire cover plate 100 is primarily borne by the hoisting equipment during the hoisting process, or, once the cover plate 100 is placed on the hoisting opening 200, its weight is mainly borne by the side wall of the hoisting opening 200. The telescopic component 300 only needs to provide tension throughout the entire process and does not need to bear the weight of the cover plate 100. This design effectively reduces the stress on the telescopic component 300, decreasing the probability of damage due to excessive weight, thereby ensuring the reliability of this embodiment and extending its service life.

[0042] Furthermore, since the telescopic component 300 is connected to the lifting port 200 and the cover plate 100 in a movable manner, this connection method greatly facilitates later maintenance and replacement work. When the telescopic component 300 malfunctions, operators can disassemble and replace the faulty component 300 individually without the need for large-scale disassembly and reinstallation of the entire roof cover assembly. This not only effectively reduces maintenance costs and downtime caused by equipment repairs but also improves maintenance efficiency, ensuring that normal factory production is not affected.

[0043] In some specific embodiments, the first connecting rod 320 and the second connecting rod 330 are respectively threaded onto the connector 310. In actual operation, the operator will first align the ends of the first connecting rod 320 and the second connecting rod 330 with the corresponding threaded holes on the connector 310, and then rotate the first connecting rod 320 and the second connecting rod 330 to gradually screw them into the connector 310 until a suitable depth is reached.

[0044] The design of using a threaded connection to drive the first connecting rod 320 and the second connecting rod 330 through the connector 310 has several significant advantages. Firstly, it greatly facilitates operators in flexibly adjusting the tension between the first connecting seat 110 and the second connecting seat 210 according to actual needs. In practical applications, different working environments, load conditions, and installation requirements necessitate varying tension requirements between the first connecting seat 110 and the second connecting seat 210. For example, under heavy loads or harsh working environments, it may be necessary to increase the tension to ensure connection stability; conversely, in situations where the tension requirement is relatively low, it can be appropriately reduced. Through the threaded connection, operators can easily change the insertion depth of the first connecting rod 320 or the second connecting rod 330 in the connector 310 by simply rotating them, thereby achieving precise adjustment of the tension. This adjustment method is simple and intuitive, requiring no complex tools or specialized knowledge, greatly improving work efficiency and ease of operation.

[0045] On the other hand, the threaded fit itself possesses the important characteristic of self-locking. Once the operator has adjusted the relative positions of the first connecting rod 320, the second connecting rod 330, and the connecting member 310, no additional locking components, such as nuts or snap rings, are needed to ensure a relatively stable positional relationship between them. This is because when the thread is subjected to external force, it generates a frictional force that hinders relative rotation, preventing the first connecting rod 320 and the second connecting rod 330 from easily loosening or shifting. This self-locking property provides a continuous and stable tension force between the first connecting seat 110 and the second connecting seat 210, effectively avoiding problems such as loosening or detachment due to unstable tension force. This ensures the reliability of this embodiment in actual use, extends the service life of the equipment, and reduces safety risks caused by connection failures.

[0046] In some specific embodiments, the threads of the first connecting rod 320 and the second connecting rod 330 have opposite directions of rotation. During actual operation, when it is necessary to adjust the tension or loosening state between the first connecting seat 110 and the second connecting seat 210, the operator will drive the connecting member 310 to rotate. Because the threads of the first connecting rod 320 and the second connecting rod 330 have opposite directions of rotation, a synergistic effect is generated during the rotation of the connecting member 310. When the connecting member 310 rotates in a certain direction, the first connecting rod 320 and the second connecting rod 330 will move in opposite directions. For example, if the connecting member 310 rotates clockwise, the first connecting rod 320 may retract towards the inside of the connecting member 310, while the second connecting rod 330 will extend outwards. Conversely, when the connecting member 310 rotates counterclockwise, the first connecting rod 320 will extend outwards, while the second connecting rod 330 will retract towards the inside of the connecting member 310.

[0047] This method of simultaneously controlling and adjusting the telescopic movement of the first connecting rod 320, the second connecting rod 330, and the connecting member 310 greatly improves the efficiency of tightening or loosening between the first connecting seat 110 and the second connecting seat 210. In traditional connection adjustment methods, it may be necessary to operate the first connecting rod 320 and the second connecting rod 330 separately, which is not only cumbersome but also time-consuming. In this embodiment, by rotating the connecting member 310, the first connecting rod 320 and the second connecting rod 330 can be simultaneously moved telescopically, quickly changing the tightness or looseness state between the first connecting seat 110 and the second connecting seat 210. Whether it is necessary to quickly tighten the first connecting seat 110 and the second connecting seat 210 to ensure the stability of the connection during installation, or to quickly loosen the connection when disassembly or adjustment is required, this design can significantly shorten the operation time, improve work efficiency, and bring great convenience to actual production and use.

[0048] In some specific embodiments, both the first connecting rod 320 and the second connecting rod 330 are fitted with elastic dust covers 340. The end of the dust cover 340 facing away from the connector 310 is fixedly connected to the first connecting rod 320 or the second connecting rod 330. The end of the dust cover 340 near the connector 310 abuts against the connector 310. The dust cover 340 is fitted outside the threads of the first connecting rod 320 and the second connecting rod 330. This is to reduce the intrusion, jamming, or corrosion of the threads on the first connecting rod 320 and the second connecting rod 330 and their connection with the connector 310 caused by rainwater and dust, ensuring the normal use of the telescopic component 300 in this embodiment and extending the service life of this embodiment.

[0049] like Figure 3 As shown, in some specific embodiments, both the first connecting part 321 and the second connecting part 331 are hooks. The opposite end faces of the first connecting seat 110 and the second connecting seat 210 are provided with hanging grooves 211. The hooks are engaged with the corresponding hanging grooves 211, which facilitates the quick connection or separation of the first connecting rod 320 and the second connecting rod 330 with the first connecting seat 110 and the second connecting seat 210 respectively when the telescopic component 300 is in a relaxed state, thereby further improving the assembly efficiency of this embodiment.

[0050] like Figure 2 As shown, in some specific embodiments, the end face of the lifting port 200 near the cover plate 100 is provided with a sealing boss 220, and the end face of the cover plate 100 near the lifting port 200 is provided with a sealing groove 120 corresponding to the sealing boss 220. The sealing boss 220 is installed in the sealing groove 120 to improve the sealing effect when the cover plate 100 blocks the lifting port 200.

[0051] In some specific embodiments, a sealing gasket 230 is provided between the sealing boss 220 and the sealing groove 120. The sealing gasket 230 may be made of a highly elastic material such as rubber. The sealing gasket 230 is pressed and squeezed together by the sealing boss 220 and the sealing groove 120, which helps to further improve the sealing performance between the cover plate 100 and the lifting port 200.

[0052] In some specific embodiments, the lifting opening 200 is provided with a drainage slope 240 on the side of the end face of the cover plate 100 facing the outer wall. The height of the drainage slope 240 near the outer wall of the lifting opening 200 is lower than the height of the inner wall of the lifting opening 200. The drainage slope 240 is used to guide rainwater that accidentally enters the gap between the cover plate 100 and the lifting opening 200, ensuring that the rainwater can be discharged quickly, avoiding water accumulation, and ensuring the protective performance of the lifting opening 200 in this embodiment.

[0053] In some specific embodiments, the end face of the cover plate 100 facing away from the lifting port 200 is an arc-shaped surface that protrudes from the lifting port 200. This improves the load-bearing capacity of the cover plate 100 and reduces the accumulation of dirt and rainwater on the cover plate 100, ensuring its reliable use.

[0054] In some specific embodiments, a protective pad 130 is laid on the end face of the cover plate 100 opposite to the lifting port 200. The protective pad 130 is specifically made of rubber, which possesses many excellent properties, making it an ideal choice for the protective pad 130. Rubber has good elasticity and can deform to a certain extent when subjected to external force, thereby absorbing and dispersing the impact energy. Simultaneously, rubber also has good wear resistance and corrosion resistance, maintaining stable performance under different environmental conditions and extending the service life of the protective pad 130.

[0055] In actual use, factory environments are often complex, with potential for falling debris such as tools and parts, and equipment that may accidentally collide with the cover plate 100 during operation. When these situations occur, the rubber protective pad 130 laid on the end of the cover plate 100 facing away from the lifting port 200 plays a crucial role. Its elasticity effectively buffers the impact of falling debris or collisions, dispersing and reducing the impact to a minimum, thereby preventing the cover plate 100 from deforming or being damaged due to excessive impact, ensuring the stable and reliable use of the cover plate 100.

[0056] In some specific embodiments, the protective pad 130 extends away from the center of the cover plate 100 and covers the telescopic assembly 300. From an overall structural perspective, the protective pad 130 acts like a protective shield, enveloping the telescopic assembly 300 and its connected first connecting seat 110 and second connecting seat 210. This design has a clear practical purpose. In real-world applications, external factors such as rain, dust, and fallen leaves often adversely affect equipment components. Rainwater is corrosive; prolonged direct contact with the telescopic assembly 300 and the first and second connecting seats 110 will gradually erode the surfaces of these components, leading to rust on metal parts and aging of plastic parts, thus affecting their performance and lifespan. Dust and fallen leaves can also accumulate in the gaps between components, hindering their normal movement and even causing malfunctions.

[0057] After the protective pad 130 covers the telescopic component 300 and the first connecting seat 110 and the second connecting seat 210, it can effectively prevent rainwater from falling directly onto these components. When rainwater falls, it will first come into contact with the protective pad 130 and then slide down its surface, without directly contacting the components below. In this way, the probability of corrosion of each component is greatly reduced, and the problems of component damage and performance degradation caused by environmental factors are reduced, thereby ensuring that this embodiment can maintain a long service life in actual use, reducing equipment maintenance costs and replacement frequency.
