The limiting claw plate 7 can adapt to glass of different widths. The top of the limiting claw plate 7 is rotatably connected to the end of the supporting plate 1. Threaded rods 8 are rotatably installed on both sides of the hanging frame 2. Both sides of the threaded rod 8 are threadedly connected to one end of the connecting rod 9. Through the rotation of the threaded rod 8, the connecting rod 9 is driven to move along its axis, which is convenient for adapting to glass of different lengths.

[0038] The lifting frame 2 is convenient for cooperation with the crane, so as to facilitate the lifting of extra-large glass. First, the threaded rod 8 is twisted according to the size of the glass, so that the connecting rod 9 can be driven to move along the axial direction of the threaded rod 8 under the thread cooperation of the connecting rod 9 and the threaded rod 8, and then it is convenient to adapt to glasses of different sizes. Then, the upper surface of the glass is abutted against the lower surface of the limiting plate 10, and the auxiliary pressure rod 12 installed on the lower side of the connecting plate 11 is rotated to move in the direction close to the limiting plate 10, so that the auxiliary pressure rod 12 presses the edge of the glass to initially limit and fix it, and then the sliding rod is pressed by operating the adjustment component. 4, so that the slide bar 4 slides downward in the limiting sleeve 3, and the slide bar 4 drives the support frame 5 to move while moving downward, and then cooperates with the rotation connection between the support frame 5 and one end of the connecting frame 6 and the rotation connection between the other end of the connecting frame 6 and the limiting claw plate 7, so that the top of the limiting claw plate 7 rotates around the two sides of the lower surface of the support plate 1, so that the two limiting claw plates 7 move toward each other until the limiting claw plates 7 clamp the glass and fix it, and then further limit the glass, and then through two limiting fixations, not only is the operation simple and convenient, but also the hoisting efficiency is improved, the flexibility of the entire device is improved, and the risk of falling off is avoided.

[0039] Embodiment 2: On the basis of embodiment 1, a lifting ring 13 is fixedly connected to the upper surface of the lifting frame 2, and a hook 14 is fixedly connected to the top of the lifting ring 13. Since it is often necessary to change the hook in the air during the lifting process, the provided hook 14 is convenient for lifting with a large crane, and the provided lifting ring 13 is convenient for changing the hook in the air with a small crane. A limit rod 15 is provided on the lower side of the lifting ring 13. One end of the limit rod 15 is fixedly connected to the lifting frame 2, and the other end of the limit rod 15 passes through the support plate 1 and the support frame 5 in sequence. The slide bar 4 is slidably sleeved in the support plate 1. The support plate 1 limits the top of the slide bar 4, and the limit rod 15 limits the bottom of the slide bar 4.

[0040] The outer wall of the slide bar 4 is provided with a limit hole 16 around it, and the limit hole 16 passes through the limit sleeve 3. The adjustment component includes a spring 17, and the spring 17 is fixedly connected between the limit sleeve 3 and the lifting plate 18. A latch 19 is provided inside the spring 17. One end of the latch 19 is slidably plugged into the limit hole 16, and the other end of the latch 19 is fixedly connected to the lifting plate 18. The spring 17 is provided to facilitate the reset of the latch 19. The two sides of the bottom end of the slide bar 4 are fixedly connected to the limit block 20, and the limit block 20 is slidably connected to the limit rod 15. By cooperating with the limit block 20 and the limit rod 15, the stability of the movement of the slide bar 4 is improved. The two ends of the upper surface of the support frame 5 are rotatably connected to one end of the connecting frame 6 through a short pin shaft, and the other end of the connecting frame 6 is rotatably connected to the inner wall of the limit claw plate 7 through a short pin shaft. The top of the limit claw plate 7 is rotatably connected to both sides of the lower surface of the support plate 1 through a long pin shaft. The bottom of the limit claw plate 7 is fixedly connected with an anti-slip strip 21. Bearing seats are installed on the support plate 1, the support frame 5, and the limit claw plate 7 to facilitate the rotation connection therebetween.

[0041] By pulling the lifting plate 18, the latch 19 is driven to move to the outside of the limiting hole 16 opened on the slide bar 4 until it slides out of the limiting hole 16. At the same time, the lifting plate 18 stretches the spring 17. At this time, the slide bar 4 can slide up and down along the limiting sleeve 3. While the slide bar 4 slides, its bottom two sides are limited by the sliding connection with the limiting rod 15 through the limiting blocks 20, thereby improving its movement stability. When the slide bar 4 is pressed to slide downward, it will drive the support frame 5 to move downward. The two ends of the upper surface of the support frame 5 are rotatably connected to one end of the connecting frame 6 through a short pin shaft, and the other end of the connecting frame 6 is rotatably connected to the inner wall of the limiting claw plate 7 through a short pin shaft, thereby driving the limiting claw plate 7 to move. The limiting claw plate 7 is The rotatable connection between its top and the supporting plate 1 rotates, thereby causing the two limiting claw plates 7 to move toward each other until the anti-slip strip 21 installed on the limiting claw plate 7 is in close contact with the edge of the glass. The anti-slip strip 21 further enhances the anti-slip property and improves the stability of the limiting claw plate 7 in limiting the glass. At this time, the lifting plate 18 is released to allow the latch 19 to be inserted into the limiting hole 16 again, thereby limiting the slide bar 4, and then limiting the limiting claw plate 7 through the limitation of the slide bar 4, and then fixing the glass through the limiting claw plate 7, thereby completing the fixation of the glass width. By adjusting the sliding distance of the slide bar 4 in the limiting sleeve 3, the opening and closing degree between the two limiting claw plates 7 can be adjusted to adapt to glass of different widths.

[0042] Embodiment 3: On the basis of embodiment 2, support seats 22 are fixedly connected to both sides of the upper surface of the support plate 1, and the threaded rod 8 is rotatably sleeved on the support seat 22. The support seat 22 provides stable support for the threaded rod 8. Limiting rings 23 are arranged on both sides of the support seat 22, and the limiting rings 23 are fixedly sleeved on the threaded rod 8. The limiting rings 23 limit the threaded rod 8 to prevent it from moving in the support seat 22. Two sections of threads are symmetrically opened on the threaded rod 8 and the rotation directions are opposite. An adjusting ring 24 is fixedly sleeved in the middle of the threaded rod 8, and the threaded rod 8 can be driven to rotate by rotating the adjusting ring 24. A fixing rod 25 is fixedly sleeved at the bottom of the support seat 22, and the top of the connecting rod 9 is slidably sleeved on the fixing rod 25. The fixing rod 25 limits the connecting rod 9. An adjusting sleeve 26 is fixedly sleeved on the upper side of the connecting plate 11, and a connecting ear 27 is fixedly connected to the lower side of the connecting plate 11.

[0043] A linkage plate 28 is provided on one side of the connecting ear 27, and the linkage plate 28 is used for transmission. The adjusting sleeve 26 is internally threaded with an adjusting rod 29, and one end of the adjusting rod 29 is fixedly sleeved with a hand wheel 30, which facilitates the rotation of the adjusting rod 29. The other end of the adjusting rod 29 is fixedly connected with an optical axis 31, one end of the linkage plate 28 is rotatably connected to the auxiliary pressure rod 12 through a small shaft 32, and the other end of the linkage plate 28 is rotatably connected to one end of the U-shaped frame 33 through a small shaft 32, and the other end of the U-shaped frame 33 is fixedly connected with a connecting block 34, and a limited bearing 35 is installed in the connecting block 34. The limited bearing 35 adopts an installation method in which the inner ring rotating ring is fixed, so that the connecting block 34 will not be driven to move when the adjusting rod 29 rotates, and one end of the optical axis 31 is fixedly sleeved on the inner ring surface of the limited bearing 35, and one end of the auxiliary pressure rod 12 is rotatably connected to the connecting ear 27 through the small shaft 32.

[0044] According to the length of the glass, the adjusting ring 24 is first twisted to drive the threaded rod 8 to rotate. Under the rotation of the threaded rod 8, the connecting rod 9 is threadedly matched with the threaded rod 8, so that the connecting rod 9 slides under the limit of the fixed rod 25, and then the distance between the two connecting rods 9 is adjusted to adapt to glasses of different lengths. Then, the upper surface of the glass is abutted against the lower surface of the limit plate 10, and then the hand wheel 30 is twisted to drive the adjusting rod 29 to rotate. Since the adjusting rod 29 is threadedly connected to the adjusting sleeve 26, the adjusting rod 29 will move upward along the axis direction of the adjusting sleeve 26. The bottom of the adjusting rod 29 is fixedly connected with the optical axis 31, thereby driving the optical axis 31 to rotate and move upward at the same time, the optical axis 31 is fixedly sleeved on the inner ring surface of the limit bearing 35, and the outer ring surface of the limit bearing 35 is fixedly connected to the connecting block 34, which will drive the connecting block 34 to move upward, and the connecting block 34 drives the auxiliary pressure rod 12 to move under the rotation cooperation between the U-shaped frame 33, the small shaft 32, and the linkage plate 28. The auxiliary pressure rod 12 is rotationally connected between one end and the connecting ear 27, so that the other end of the auxiliary pressure rod 12 rotates close to the limit plate 10 until the auxiliary pressure rod 12 is pressed against the lower surface of the glass, thereby completing the fixation of the glass in the length direction.
