[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 6 As shown, this utility model proposes a complex roof clamp-type suspended basket support leg reinforcement device, including a roof pergola beam 8, and a support leg base 1 placed on the roof pergola beam 8. The support leg base 1 is a steel plate with bolt holes. A U-shaped clamp 2 spans the top of the roof pergola beam 8. High-strength bolts 5 pass through the bolt holes of the support leg base 1 and both ends of the U-shaped clamp 2 to lock the support leg base 1 to the roof pergola beam 8. A support leg steel square tube 4 is welded to the upper surface of the support leg base 1. A bracket 11 is welded to the top of the support leg steel square tube 4. The bracket has fixing holes. The suspended basket crossbeam 9 is fixed to the bracket 11 by bolts. A reverse pull steel wire rope 10 is connected at one end to the tail of the suspended basket crossbeam 9 and the other end is wrapped around the roof pergola beam 8 and fixed.

[0037] Furthermore, a protective steel plate 7 is provided between the contact surface of the support base 1 and the roof truss beam 8. Angle iron lugs 3 are welded at the four corners of the support base 1, the connection between the support steel square tube 4 and the bracket 11. The bolt holes of the support base 1 are strip holes, and their length direction is perpendicular to the axis of the roof truss beam 8. Adjustable shims 6 are provided at the connection between the bracket 11 and the hanging basket beam 9.

[0038] like Figures 7 to 11 As shown, in this embodiment, the reinforcement device also includes a suspended basket 35 connected to the suspended basket beam 9, and a drive mechanism fixedly installed on the suspended basket beam 9 to control the lifting and lowering of the suspended basket 35. The drive mechanism includes a winch 12 rotatably installed on the suspended basket beam 9, one end of the steel cable 36 being fixedly connected to the winch 12, and a motor 13 fixedly installed on the suspended basket beam 9. The output shaft of the motor 13 is coaxially fixedly connected to the winch 12. By driving the winch 12 to rotate through the motor 13, the steel cable 36 can be wound and released, thereby driving the suspended basket 35 to lift and lower.

[0039] As one implementation, the reinforcement device also includes a buffer component fixedly installed on the crossbeam 9 of the suspended platform. When the winch 12 becomes loose, the suspended platform 35 decelerates and stops. When the winch 12 or the motor 13 goes out of control, the suspended platform will fall rapidly under the action of gravity. A locking protection mechanism is required to lock the suspended platform. However, the traditional locking protection mechanism will stop the rapidly moving suspended platform instantly, causing the outrigger base 1 to be subjected to a large load impact, which can easily affect the stability of the structure. Therefore, a buffer component is required to prevent the suspended platform 35 from falling and to prevent the suspended platform from stopping instantly.

[0040] Furthermore, the buffer component includes a drive shaft 14 fixedly mounted on the winch 12 and a clamping plate 15 rotatably mounted on the basket beam 9. The clamping plate 15 has multiple clamping slots 16. A disc 17 is fixedly mounted on the drive shaft 14. The disc 17 has a cavity 18. A sliding plate 19 is slidably mounted in the cavity 18. A first elastic element 20 is fixedly mounted between the sliding plate 19 and the cavity 18. A locking rod 21 is fixedly mounted on the sliding plate 19. A counterweight 22 is fixedly mounted on the locking rod 21. When the motor 13 drives the winch 12 to rotate, the winch 12 will drive the disc 17 to rotate through the drive shaft 14, thereby driving the locking rod 21. During normal operation, the locking rod 21 rotates at a low speed, and its centrifugal force is insufficient to overcome the restriction of the first elastic element 20. At this time, the locking rod 21 will not enter the slot 16 and engage with it. When the basket 35 falls, the rotating speed of the disc 17 is relatively high. Under the action of centrifugal force, the locking rod 21 will enter the slot 16, thereby driving the locking plate 15 to rotate. Under the action of friction between the slot 16 and the locking rod 21, even if the disc 17 does not rotate, the locking rod 21 still cannot disengage from the slot 16, so that the basket 35 remains stable after stopping.

[0041] Furthermore, a connecting plate 23 is fixedly installed on the card plate 15, and a limit box 24 is fixedly installed on the basket beam 9. A limit plate 25, coaxially fixedly connected to the connecting plate 23, is rotatably installed inside the limit box 24. A first sealing block 26 is provided inside the limit box 24, and a second sealing block 27 is fixedly installed on the limit plate 25. A receiving box 28 is fixedly installed on the basket beam 9, and a partition 29 is slidably installed inside the receiving box 28. A pull rod 30 is fixedly installed on the partition 29, and a second elastic element 31 is fixedly installed between the pull rod 30 and the receiving box 28. When the card plate 15 rotates, it will drive the connecting plate 23 to rotate, thereby causing the limit plate 25 to rotate. Because the first sealing block 26 and the second sealing block 27 block the internal space of the limit box 24, when the limit plate 25 rotates, it will continuously squeeze a part of the internal space of the limit box 24.

[0042] The limiting box 24 is fixedly equipped with a conveying pipe 32, the other end of which is connected to the bottom of the receiving box 28. A valve 33 is fixedly installed on the conveying pipe 32, the valve 33 including a valve body and a valve core. A connecting shaft 34 is fixedly installed on the limiting plate 25, the other end of which is coaxially fixedly connected to the valve core. The limiting box 24 is filled with hydraulic medium. The rotating limiting plate 25 will squeeze the hydraulic medium inside the limiting box 24 through the second sealing block 27. The squeezed hydraulic medium will enter through the conveying pipe 32. The contents are placed inside the receiving box 28, causing the partition 29 to rise and compressing the second elastic element 31. At the same time, the valve core rotates, gradually reducing the effective flow area inside the valve 33. As the flow area gradually decreases, the flow rate through the valve 33 per unit time gradually decreases, which in turn causes the rotation speed of the limit plate 25 to gradually slow down. This gradually slows down the rotation speed of the runaway winch 12, thereby gradually decelerating and stopping the suspended platform 35, preventing the suspended platform 35 from impacting the outrigger base 1 when it stops abruptly.

[0043] In this embodiment, the support leg base 1 is made of support leg steel square tube 4. The support leg steel square tube 4 is welded to the top support groove 11 and the bottom support leg base 1, and fixed with angle iron lugs 3. An angle iron lug 3 is set around the support leg base 1 and the support leg steel square tube 4, and an angle iron lug 3 is set in the direction of the top support groove 11 on the support leg steel square tube 4 and the top support groove 11, for a total of 6 angle iron lugs 3 for reinforcement, so as to enhance the stability of the support leg base 1.

[0044] The top bracket 11 has an upward opening and holes on both sides for fixing the basket crossbeam 9. High-strength bolts 5 are used for fixing, and the cantilever length of the front crossbeam can be adjusted according to different environments.

[0045] To ensure the safety of the suspended platform 35, a counter-pull steel wire rope 10 is installed at the tail of the crossbeam 9 of the suspended platform. The counter-pull steel wire rope 10 is fixed to the roof truss beam 8. To ensure that the roof truss beam 8 is not damaged during fixing, the counter-pull steel wire rope 10 is wrapped around the roof truss beam 8 once for fixing, and a rubber ring is used for protection on the contact surface with the roof truss beam 8.

[0046] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
