DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides an embodiment: a bridge construction safety hanging basket, including a hanging basket body 1, a lifting mechanism is arranged on the surface of the hanging basket body 1, the lifting mechanism includes a guide rail 2, the guide rail 2 is fixedly connected to the surface of the hanging basket body 1, a first slider 21 is slidably connected to the surface of the guide rail 2, a platform lifting frame 22 is fixedly connected to the surface of the first slider 21, a lifting end of the platform lifting frame 22 is fixedly connected to a guardrail 23, a protective door 24 is rotatably connected to the surface of the guardrail 23, a support block 25 is fixedly connected to the surface of the hanging basket body 1, and a support block 25 is fixedly connected to the surface of the support block 25. A motor 26 is connected, and the surface of the support block 25 is fixedly connected with the motor 26. A screw rod 27 is fixedly connected to the output shaft of the motor 26. The motor 26 drives the screw rod 27 to rotate through the output shaft. A nut 28 is threadedly connected to the surface of the screw rod 27. The nut 28 is fixedly connected to the bottom of the platform lifting frame 22. Its lifting mechanism can change the working height of some workers, thereby avoiding inconvenience for some workers and improving work efficiency. The lifting position can be moved on the hanging basket body 1 to ensure that the workers can work at the specified position, thereby improving the flexibility of the lifting mechanism.

[0024] A following mechanism is provided on the surface of the platform lifting frame 22, and the following mechanism includes a fixed block 3, which is fixedly connected to the bottom of the platform lifting frame 22, and the bottom of the platform lifting frame 22 is rotatably connected to a support plate 31, and a clamping block 32 is fixedly connected to the lower surface of the support plate 31, and a second slider 33 is slidably connected to the surface of the guide rail 2, and the clamping block 32 is clamped and connected to the surface of the second slider 33, and a limiting bolt 34 is threadedly connected to the surface of the fixed block 3. The following mechanism can follow the platform lifting frame 22 to move horizontally on the surface of the hanging basket body 1, so that the staff can follow the platform lifting frame 22 to move on the surface of the hanging basket body 1. During the work, the workers do not need to move horizontally, which reduces the labor intensity of the workers.

[0025] Two groups of guide rails 2 are provided on one side of the hanging basket body 1, and four groups of first sliders 21 are provided. The platform lifting frame 22 slides on the surface of the hanging basket body 1 through the guide rails 2 and the first sliders 21. The platform lifting frame 22 moves linearly on the surface of the hanging basket body 1. The worker can stand on the lifting end of the platform lifting frame 22. The platform lifting frame 22 drives the lifting end to drive the worker to lift. The platform lifting frame 22 can also drive the worker to move on the surface of the hanging basket body 1. The lifting end of the guardrail 23 drives the guardrail 23 and the guard door 24 to rise and fall synchronously. During the movement of the platform lifting frame 22 on the surface of the hanging basket body 1, the guardrail 23 and the guard door 24 follow the movement. The guardrail 23 and the guard door 24 at the lifting end of the platform lifting frame 22 prevent the worker from falling from the platform lifting frame 22. The worker opens the guard door 24 on the guardrail 23 to enter the lifting end of the platform lifting frame 22. Two groups of nuts 28 are provided. The screw rod 27 drives the nuts 28 to move during the rotation on the support block 25. The nuts 28 drive the platform lifting frame 22 to slide on the surface of the hanging basket body 1, thereby realizing the automatic sliding of the platform lifting frame 22 on the surface of the hanging basket body 1. There is no need to manually adjust the position of the platform lifting frame 22 on the hanging basket body 1, which saves time and effort.

[0026] A slot is provided on the surface of the second slider 33, and the block 32 is rotatably engaged with the slot of the second slider 33 through the support plate 31. The support plate 31 limits the position of the second slider 33 on the guide rail 2 through the block 32. When the platform lifting frame 22 slides on the hanging basket body 1, it will drive the support plate 31 to slide synchronously, and the support plate 31 drives the second slider 33 to slide on the surface of the guide rail 2 through the block 32, thereby realizing the synchronous sliding of the platform lifting frame 22 and the second slider 33. A threaded hole is provided on the surface of the fixing block 3, and a limiting bolt 34 is threadedly connected to the threaded hole of the fixing block 3. The limiting bolt 34 limits the angle of the support plate 31 on the fixing block 3. When the support plate 31 is parallel to the horizontal plane, the limiting bolt 34 is on the upper surface of the support plate 31, and the second slider 33 is on the lower surface of the support plate 31, thereby limiting the position of the support plate 31. When the support plate 31 is perpendicular to the horizontal plane, one side of the support plate 31 contacts and is connected to the platform lifting frame 22, and the other side of the second support plate 31 contacts and is connected to the limiting bolt 34, thereby limiting the position of the support plate 31.

[0027] Working principle: The output shaft of the motor 26 drives the screw rod 27 to rotate on the support block 25. The support block 25 drives the nut 28 to move during the rotation. The nut 28 drives the platform lifting frame 22 to move. The platform lifting frame 22 slides on the surface of the basket body 1 through the first slider 21 and the guide rail 2, thereby realizing the linear movement of the platform lifting frame 22 on the surface of the basket body 1. The lifting end of the platform lifting frame 22 drives the guardrail 23 and the guard door 24 to rise and fall at the same time. The worker stands on the platform lifting frame 22 to work, which can change the working height of some workers on the basket body 1. In combination with the height change of the upper basket body 1, the workers can work at different horizontal heights. At the same time, the guardrail 23 and the guard door 24 can prevent the workers on the platform lifting frame 22 from falling. The platform lifting frame 22 can also move on the basket body 1, thereby realizing the height adjustment of different positions.

[0028] The second slider 33 is slid on the surface of the guide rail 2, and the support plate 31 is rotated on the surface of the hanging basket body 1 through the fixed block 3, so that the support plate 31 rotates parallel to the horizontal plane, and the block 32 on the support plate 31 is rotated to be engaged with the slot of the second slider 33. At this time, the platform lifting frame 22 drives the support plate 31 and the second slider 33 to slide on the surface of the hanging basket body 1, and the second slider 33 supports the side of the support plate 31 away from the platform lifting frame 22. The limiting bolt 34 is rotated on the surface of the fixed block 3 so that the limiting bolt 34 limits the position of the support plate 31. At this time, the worker stands on the support plate 31 to work, and the support plate 31 can drive the worker to move, thereby changing the position of the worker on the hanging basket body 1, reducing the labor of the staff walking back and forth.
