[0022] like Figure 1 As shown, a car roof lifting device includes a frame 7. In this design, the frame 7 is a rectangular grid frame structure, welded together from multiple horizontal and vertical beams. The frame includes two planes: a flat section and an inclined section. Figure 1 In the indicated direction, the inclined section is located on the right side of the flat section. The right side of the longitudinal beam (along the left and right direction) can be bent at a certain angle to form a corresponding crossbeam. The inclined section extends diagonally downward to the right relative to the flat section. The inclined section and the flat section are set at an obtuse angle, and the obtuse angle is preferably not less than 150 degrees. The top of the flat section of the frame 7 is provided with four lower lifting rings 9. Each of the lower lifting rings 9 is connected to a sling 10. The upper ends of the four slings 10 are connected to an upper lifting ring 11.

[0023] Suction cup assemblies are provided on both the inclined and flat bottom surfaces of frame 7, such as... Figure 1 In the design, two suction cup assemblies are positioned at the bottom two corners of the beveled portion, and four are positioned on the flat portion. In other embodiments, other numbers and distributions may be used. The suction cup assembly includes movable suction cup assemblies and fixed suction cup assemblies.

[0024] like Figure 1 As shown, the fixed suction cup assembly includes a fixed suction cup 5, which is directly mounted on the frame 7 via a fixed connecting plate. This fixed connecting plate is fixedly disposed on the bottom surface of the crossbeam and / or longitudinal beam, as shown in... Figure 1 In the middle, the suction cup assemblies located at the two corners of the inclined section are fixed suction cup assemblies, and the fixed connecting plates of the two are set at the corners where the crossbeam and the longitudinal beam connect; two fixed suction cup assemblies are set on the flat section, and the fixed connecting plates of the two fixed suction cup assemblies are located at the bottom of the outermost longitudinal beam of the flat section.

[0025] The movable suction cup assembly includes a sliding sleeve 3, which can be a combination of a U-shaped plate and a movable connecting plate, such as... Figure 1As shown, the U-shaped opening of the U-shaped plate is buckled from top to bottom on the longitudinal beam of the rack 7, the movable connecting plate is fixedly connected with the U-shaped plate below the longitudinal beam, thereby surrounding the longitudinal beam and enabling the sliding sleeve 3 to move along the longitudinal beam. Further, a limiting block 13 is arranged on the longitudinal beam where the sliding sleeve 3 is installed, and the sliding sleeve 3 abuts against the limiting block 13 when it moves to a set position, thereby limiting the movement range of the sliding sleeve 3. Meanwhile, a threaded hole is formed in the sliding sleeve 3, i.e. in the U-shaped plate or the movable connecting plate, and a locking bolt 4 is installed in the threaded hole. The threaded end of the locking bolt 4 is pressed against the surface of the longitudinal beam after passing through the sliding sleeve 3, thereby locking the position of the sliding sleeve 3. The movable connecting plate extends outwardly from the longitudinal beam, and a movable suction cup 14 is installed on the movable connecting plate. In other embodiments, the movable suction cup assembly can also be arranged on the cross beam of the rack 7.

[0026] The rack 7 is also provided with a vacuum generator 12, which is connected to the fixed suction cups 5 and the movable suction cup 14. A first reversing valve 1 is arranged on the connecting pipeline of the vacuum generator 12 and the fixed suction cups 5 and the movable suction cup 14. The vacuum generator 12 provides negative pressure for each fixed suction cup and movable suction cup, and can be depressurized through the first reversing valve 1.

[0027] Further, a sunroof fixing assembly is installed on the rack 7, as shown in Figure 1 As shown, the sunroof fixing assembly includes two telescopic cylinders 6, the cylinder rods of which are arranged opposite to each other. A clamping plate 8 is arranged on the cylinder rod of each telescopic cylinder 6. The clamping plate 8 is perpendicular to the planar part of the rack 7. Two flat plates are arranged on the side surface of the clamping plate 8 opposite to the telescopic cylinder 6. The two flat plates are arranged at a certain distance apart, and the clamping plate 8 and the two flat plates form a clamping groove. As can be seen, the two clamping grooves are arranged opposite to each other. In another embodiment, the sunroof fixing assembly can be arranged in two groups. The telescopic cylinders 6 of the two groups of sunroof fixing assemblies are arranged along the cross beam and the longitudinal beam, respectively. A second reversing valve 2 is arranged on the rack. The telescopic cylinders 6 are connected to an external air source through the second reversing valve 2.

[0028] The use process of the present hoisting device is as follows. According to the center of gravity of the current hoisted automobile roof (which can be determined by design software during the development stage of the vehicle part), the position of the sliding sleeve 3 on the installed longitudinal beam or cross beam is adjusted, so that the load of each movable suction cup and fixed suction cup is basically the same (the specific position of the movable suction cup can be obtained by calculation according to the center of gravity of the roof). Then, the position of the movable suction cup assembly is fixed by the locking bolt 4. During hoisting, the automobile roof can be sucked according to the predetermined position. After the automobile roof is transported or installed, the suction cups are depressurized by turning the first reversing valve, so that the automobile roof can be released.

[0029] For the vehicle with sunroof, after the suction cup sucks the roof, the telescopic cylinder 6 is elongated by external air source, the two (or four) clamping plates are expanded, the groove on the clamping plate is clamped on the inner edge of the sunroof, and the connection strength of the hoisting and grabbing is further improved.
