Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly to an opening and closing roof. Background Art

[0002] Due to the requirements of ventilation and fire protection, it is usually necessary to provide opening windows or movable roofs on the daylighting roof of a building. Waterproofing the top is more difficult than the facade, and adding the need for opening further tests the design, processing, and installation levels. When the traditional movable roof is opened, a vertical mechanical lifting device is required to separate the sealing rubber strip between the movable roof and the roof frame. However, the transmission part of the vertical mechanical lifting device is concentrated at one position, with limited driving force, requiring the cooperation of multiple mechanisms, resulting in a complex structure and high cost. Moreover, the vertical mechanical lifting device has a weak adaptability to the deformation and error of the load-bearing structure. Temperature difference deformation, settlement deformation, and installation error of the building structure itself are likely to cause the vertical mechanical lifting device to malfunction, restricting the application of the movable roof. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an opening and closing roof that can achieve the vertical lifting of the movable roof without a vertical mechanical lifting device to facilitate the opening of the roof.

[0004] To solve the above technical problem, the object of the present invention is achieved through the following technical solutions: An opening and closing roof is provided, which is arranged on the main structure of a building and includes a roof fixed frame, a track system, and a movable roof. The roof fixed frame is fixed to the main structure; the track system is fixedly installed on the main structure and is provided with a driving device. The track of the track system is provided with a plurality of pits at intervals along its length, and the inner wall of the side of the pit is inclined outward from bottom to top to form a guiding surface; the movable roof is arranged on the track system and includes a roof main body and a trolley system. The trolley system is slidably installed on the track system and is fixedly connected to the roof main body. A transmission rack mechanism connected to the driving device is fixedly connected to the roof main body. The extending direction of the rack of the transmission rack mechanism is consistent with the length direction of the track of the track system. The driving device meshes with the rack of the transmission rack mechanism to drive the transmission rack mechanism to move and drive the trolley system to move along the track system; when the opening and closing roof is in a closed state, the wheels of the trolley of the trolley system are all located at the bottom horizontal plane of the pit, and the sealing rubber strip of the roof main body and the sealing rubber strip of the roof fixed frame are pressed against each other for sealing.

[0005] Its further technical solution is as follows: There are two sets of the track system, the roof fixing frame and the movable roof, which are symmetrically arranged left and right. The two roof fixing frames are respectively arranged on the outer sides of the corresponding movable roofs. The roof bodies of the two movable roofs are connected in a matching manner. The number of the track system, the trolley system, the driving device and the transmission rack mechanism is the same and their distribution positions are symmetrical.

[0006] Its further technical solution is as follows: A buffer system is further arranged on the main structure. The buffer system includes an end face limit buffer installed at the tail end of the track system.

[0007] Its further technical solution is as follows: The number of tracks of the track system is multiple, and they are arranged in parallel side by side on the main structure. The trolley system includes multiple trolleys. A plurality of trolleys are connected to the roof body along the length direction of each track corresponding to each track. The trolley includes a guiding trolley.

[0008] Its further technical solution is as follows: The trolley further includes a first trolley. The number of guiding trolleys is one more than the number of first trolleys. Among them, the two guiding trolleys are respectively arranged at both ends of the roof body along the length direction of the corresponding track, and the guiding trolleys and the first trolleys are arranged alternately at intervals.

[0009] Its further technical solution is as follows: The number of guiding trolleys is four, and the number of first trolleys is three. When the opening and closing roof is in the closed state, the center distances between the pits corresponding to the three guiding trolleys far from the roof fixing frame and the pits corresponding to the first trolley adjacent to the guiding trolley are 0.3m, 0.4m and 0.5m in sequence along the direction towards the roof fixing frame.

[0010] Its further technical solution is as follows: When the opening and closing roof is in the closed state, the center distances between the pits corresponding to the three guiding trolleys close to the roof fixing frame and the pits corresponding to the first trolley adjacent to the guiding trolley are 2.5m, 2.4m and 2.3m in sequence along the direction away from the roof fixing frame.

[0011] Its further technical solution is as follows: The roof fixing frame is located in the middle of the track and is arranged on one side of the track. The pits are distributed between the front end and the middle of the track.

[0012] Its further technical solution is as follows: The length of the top surface of the pit is 78mm, the depth is 8mm, and the length of the horizontal plane at the bottom of the pit is 18mm.

[0013] The beneficial technical effects of the present invention are as follows: An opening and closing roof of the present invention includes a roof fixing frame, a track system and a movable roof. By arranging a driving device on the track system, a trolley system slidably installed on the track system is fixedly connected to the roof body of the movable roof. A transmission rack mechanism connected to the driving device is fixedly connected to the roof body of the movable roof. The driving device meshes with the rack of the transmission rack mechanism to drive the transmission rack mechanism to move, thereby driving the roof body to move and enabling the trolley system to move along the track system, realizing the opening and closing of the movable roof. At the same time, by arranging a pit on the track of the track system, the inner side wall of the pit inclines outward from bottom to top to form a guiding surface. When the opening and closing roof is in a closed state, the wheels of the trolley of the trolley system are all located at the bottom horizontal plane of the pit, and the sealing rubber strips of the roof body and the roof fixing frame are pressed against each other for sealing. When the roof body moves, the wheels of the trolley of the trolley system can move upward along the guiding surface, causing the roof body to rise, and the sealing rubber strips of the roof body and the roof fixing frame are separated, avoiding friction and running resistance between the sealing rubber strips, realizing the vertical lifting of the movable roof without a vertical mechanical lifting device, preventing operation errors of the vertical mechanical lifting device, facilitating the opening of the roof, and improving the accuracy, safety and stability of the roof opening.

[0028] Please refer to Figures 1 to 8 as shown in Figure 1 a roof plan view of an opening and closing roof in a closed state provided by an embodiment of the present invention, Figure 2A sectional view of an opening and closing roof in a closed state provided by an embodiment of the present invention. The opening and closing roof 10 is arranged on the main structure 20 of a building, and includes a roof fixed frame 11, a track system 13 and a movable roof 12. The roof fixed frame 11 is fixed on the main structure 20. The track system 13 is fixedly installed on the main structure 20, and a driving device 14 is arranged on the track system 13. A plurality of pits 15 are spaced along the length of the track 131 of the track system 13, and the inner side walls of the pits 15 are inclined upward and outward from bottom to top to form guiding surfaces. The movable roof 12 is arranged on the track system 13 and includes a roof main body 121 and a trolley system 16. The trolley system 16 is slidably installed on the track system 13 and fixedly connected to the roof main body 121. A transmission rack mechanism 17 connected to the driving device 14 is fixedly connected to the roof main body 121. The extending direction of the rack of the transmission rack mechanism 17 is consistent with the length direction of the track 131 of the track system 13. The driving device 14 meshes with the rack of the transmission rack mechanism 17 to drive the transmission rack mechanism 17 to move, thereby driving the trolley system 16 to move along the track system 13. When the opening and closing roof 10 is in a closed state, the wheels 162 of the trolley 161 of the trolley system 16 are all located at the bottom horizontal plane of the pits 15, and the sealing rubber strips of the roof main body 121 and the roof fixed frame 11 are pressed against each other to seal. The wheels 162 of the trolley 161 of the trolley system 16 can be guided by the guiding surfaces to move along the length direction of the track 131 to raise the movable roof 12.

[0029] Among them, the driving device 14 can be a motor sleeved with a gear, and the gear meshes with the rack of the transmission rack mechanism 17 to drive the gear to rotate according to the rotation of the motor, so that the rack moves, and the transmission rack mechanism 17 drives the roof body 121 to move, providing power for the trolley system 16 to move along the track system 13. The opening and closing roof 10 includes a roof fixing frame 11, a track system 13 and a movable roof 12. By arranging the driving device 14 on the track system 13, a trolley system 16 slidably installed on the track system 13 is fixedly connected to the roof body 121 of the movable roof 12, and a transmission rack mechanism 17 connected to the driving device 14 is fixedly connected to the roof body 121 of the movable roof 12. The driving device 14 meshes with the rack of the transmission rack mechanism 17 to drive the transmission rack mechanism 17 to move, thereby driving the roof body 121 to move and enabling the trolley system 16 to move along the track system 13, realizing the opening and closing of the movable roof 12. At the same time, by arranging a concave pit 15 on the track 131 of the track system 13, the inner wall of the side of the concave pit 15 is inclined upward and outward along the length direction of the track 131 to form a guiding surface. When the opening and closing roof is in a closed state, the wheels 162 of the trolley 161 of the trolley system 16 are all located at the bottom horizontal plane of the concave pit 15, and the sealing rubber strips of the roof body 121 are pressed against the sealing rubber strips of the roof fixing frame 11 for sealing. When the roof body 121 starts to move, the wheels 162 of the trolley 161 of the trolley system 16 can move upward along the guiding surface, causing the roof body 121 to rise, and the sealing rubber strips of the roof body 121 are separated from the sealing rubber strips of the roof fixing frame 11, avoiding friction and running resistance between the sealing rubber strips, realizing the vertical lifting of the movable roof 12 without a vertical mechanical lifting device, preventing operation errors of the vertical mechanical lifting device, facilitating the opening of the roof, and improving the accuracy, safety and stability of the roof opening.

[0030] Specifically, two track systems 13, roof fixing frames 11 and movable roofs 12 are symmetrically arranged on the left and right, and the two roof fixing frames 11 are respectively arranged outside the corresponding movable roofs 12. The roof bodies 121 of the two movable roofs 12 are cooperatively connected, and the track systems 13, trolley systems 16, driving devices 14 and transmission rack mechanisms 17 are the same in number and symmetrically distributed. The symmetrically arranged movable roof 12, track system 13 and roof fixing frame 11 can improve the opening and closing efficiency and increase the aesthetics. Figure 1 The arrow in the figure indicates the opening movement direction of the movable roof 12.

[0031] Specifically, a buffer system 18 is further provided on the main body structure 20. The buffer system 18 includes an end face limit buffer installed at the tail end of the track system 13. Among them, the setting of the end face limit buffer can prevent the roof body 121 of the movable roof 12 from detaching from the track 131 of the track system 13 when the movable roof 12 is opened, and can control the moving distance of the movable roof 12. Preferably, the buffer system 18 may further include an intermediate buffer disposed between the two movable roofs 12 to prevent damage caused by collision between the roof bodies 121 of the two movable roofs 12 when the opening and closing roof 10 is closed.

[0032] Specifically, the number of the tracks 131 of the track system 13 is multiple, and they are arranged side by side and parallel to each other on the main body structure 20. The trolley system 16 includes a plurality of trolleys 161. A plurality of trolleys 161 are connected to the roof body 121 corresponding to each track 131 along the length direction of the track 131. The trolley 161 includes a guiding trolley. Among them, the guiding trolley refers to the trolley 161 with guiding wheels. Preferably, the trolley 161 further includes a first trolley. The number of the guiding trolleys is one more than the number of the first trolleys. Among them, the two guiding trolleys are respectively disposed at both ends of the roof body 121 along the length direction of the corresponding track 131, and the guiding trolleys and the first trolleys are alternately arranged at intervals. The first trolley refers to the trolley 161 without guiding wheels.

[0033] Specifically, the number of the guiding trolleys is four, and the number of the first trolleys is three. When the opening and closing roof 10 is in the closed state, the center distances between the pits 15 corresponding to the three sequentially arranged guiding trolleys away from the roof fixing frame 11 and the pits 15 corresponding to the first trolleys adjacent to the guiding trolleys are 0.3 m, 0.4 m, and 0.5 m in sequence along the direction towards the roof fixing frame 11. The relatively large spacing between the pits 15 can avoid the fluctuation phenomenon generated when the trolley 161 falls into the pit 15 during the movement of the roof due to the relatively flexible roof, so that the movable roof 12 can be opened and closed smoothly. Preferably, when the opening and closing roof 10 is in the closed state, the center distances between the pits 15 corresponding to the three sequentially arranged guiding trolleys close to the roof fixing frame 11 and the pits 15 corresponding to the first trolleys adjacent to the guiding trolleys are 2.5 m, 2.4 m, and 2.3 m in sequence along the direction away from the roof fixing frame 11. Thus, when the movable roof 12 is opened, the guiding trolleys and the first trolleys are sequentially suspended when moving along the direction close to the corresponding roof fixing frame 11, and only one trolley 161 is suspended each time. Among them, the number of the pits 15 is the same as the total number of the trolleys 161 slidably installed on the corresponding track 131, and the spacing of the pits 15 enables only one trolley 161 to be in a suspended state during the movement of all the trolleys 161 on the same track 131, and the trolleys 161 other than the suspended trolley 161 on the track 131 are all in full contact with the track 131 and in a stressed state, making the movement of the movable roof 12 safer and more stable.

[0034] Specifically, the roof fixing frame 11 is located in the middle of the track 131 and arranged on one side of the track 131, and the pits 15 are distributed between the front end and the middle of the track 131. Preferably, the driving device 14 is located on one side of the track 131.

[0035] Specifically, the length of the top surface of the pit 15 is 78 mm, the depth is 8 mm, and the length of the bottom horizontal plane of the pit 15 is 18 mm. Among them, the walking and positioning accuracy of the trolley 161 of the trolley system 16 can be 5 mm, so it can be ensured that when the opening and closing roof 10 is in the closed state, when all the trolleys 161 stop, they are all located on the bottom horizontal plane of the pit 15, and the movable roof 12 and the roof fixing frame 11 are in close contact with each other.

[0036] In summary, an opening and closing roof of the present invention includes a roof fixed frame, a track system and a movable roof. By arranging a driving device on the track system, a trolley system slidably installed on the track system is fixedly connected to the roof body of the movable roof. A transmission rack mechanism connected to the driving device is fixedly connected to the roof body of the movable roof. The driving device meshes with the rack of the transmission rack mechanism to drive the transmission rack mechanism to move, thereby driving the roof body to move and enabling the trolley system to move along the track system, realizing the opening and closing of the movable roof. At the same time, by arranging a concave pit on the track of the track system, the inner wall of the side of the concave pit is inclined upward and outward along the length direction of the track to form a guiding surface. When the opening and closing roof is in a closed state, the wheels of the trolley of the trolley system are all located at the bottom horizontal plane of the concave pit, and the sealing rubber strips of the roof body and the sealing rubber strips of the roof fixed frame are pressed against each other for sealing. When the roof body moves, the wheels of the trolley of the trolley system can move upward along the guiding surface, causing the roof body to rise, and the sealing rubber strips of the roof body and the sealing rubber strips of the roof fixed frame are separated, avoiding friction and running resistance between the sealing rubber strips, realizing the vertical lifting of the movable roof without a vertical mechanical lifting device, preventing operation errors of the vertical mechanical lifting device, so as to open the roof, and improving the accuracy, safety and stability of roof opening.

[0037] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
