Technical Field

[0001] This utility model relates to the field of high-altitude work protection, and in particular to the safety guardrail structure of high-altitude lifting platform. Background Technology

[0002] In the industrial and construction sectors, aerial work platforms are widely used, facilitating various operations such as equipment installation, maintenance, and construction at heights. Safety railings for aerial work platforms are typically installed around the platform's edge, forming a closed or semi-closed protective area. A common frame structure consists of columns, crossbars, and connectors.

[0003] For basic protection, the columns are vertically fixed to the edge of the platform as the main support. Multiple horizontal bars connect the columns to form a frame outline. Protective railings or mesh panels are installed in the frame. With their own strength and reasonable gap design, they directly prevent people and objects from falling, forming a basic physical barrier.

[0004] During high-altitude operations, rainwater can directly enter the work platform during rainy weather, making the platform surface slippery and increasing the risk of workers slipping and falling. It can also wet work tools and materials, affecting the normal progress of the work, reducing construction efficiency, and workers are easily soaked by rainwater, which can harm their health.

A connecting frame 115 is provided on one side of the moving block 107. A slot 116 is provided above the connecting frame 115. The rotating roller 112 is driven to rotate by starting the motor 2. The rotation of the rotating roller 112 causes the rain curtain 113 to unfold from the rotating roller 112. The sliding frame 110 is moved to make the rain curtain 113 slide in the opposite direction to the rotating roller 112, so that the rain curtain 113 unfolds. By locking the locking block 114 into the slot 116, the rain curtain 113 is fixed to the connecting frame 110. Above the frame 115, the starting motor 103 drives the threaded rod 104 to rotate. The rotation of the threaded rod 104 causes the moving block 107 to move linearly above the threaded rod 104 and the sliding rod 105. This allows the rain curtain 113 to be adjusted to a suitable position according to different heights. By controlling the second motor, the rotating roller 112 rotates in the opposite direction. The reverse rotation of the rotating roller 112 causes the rain curtain 113 to move in the direction of the rotating roller 112, thus allowing the rain curtain 113 to be retracted. This makes it convenient for the rain curtain 113 to be unfolded and retracted, and convenient for staff to use.

[0022] Please see Figures 2-4In this embodiment, a caster wheel 201 is fixedly connected to the lower part of the support base 101, and mounting brackets 202 are fixedly connected to both sides of the support base 101. A hydraulic push rod 203 is provided above the mounting brackets 202, and a support base plate 204 is fixedly connected to one side of the hydraulic push rod 203. The device is moved to the required position by the caster wheel 201, and the support base plate 204 is pushed downward by controlling the hydraulic push rod 203. When the support base plate 204 contacts the ground, the caster wheel 201 is disengaged from the ground, thereby fixing the device to the ground and preventing displacement. The telescopic assembly includes a motor 301, a threaded rod 302, a fixing block 303, a sliding block 304, and a telescopic rod 305. The motor 301 is provided on the outer side of the support base 101, and the support base 101 is equipped with a... A fixed block 303 is provided, and a threaded rod 302 is provided on one side of the fixed block 303. The threaded rod 302 is connected to the motor 301. A sliding block 304 is connected above the threaded rod 302. Multiple sets of telescopic rods 305 are rotatably connected above the sliding block 304 and the fixed block 303. The top of the telescopic rod 305 is rotatably connected to a fixed support block 306. The work platform 102 is fixedly connected above the fixed support block 306. By starting the motor 301, the threaded rod 302 is driven to rotate. The rotation of the threaded rod 302 drives the sliding block 304 to move. When the moving block 107 moves towards the fixed block 303, it drives the telescopic rods 305 to unfold upward. The unfolding of the telescopic rods 305 raises the work platform 102, thereby allowing the height of the work platform 102 to be adjusted.

[0023] Please see Figures 3-5In this embodiment, a ladder 401 is fixedly connected to one side of the work platform 102, a protective plate 402 is fixedly connected to the top of the work platform 102, a protective door 403 is rotatably connected to one side of the protective plate 402, a snap-fit ​​block 404 is provided above the work platform 102, and a snap-fit ​​buckle 405 is rotatably connected above the protective door 403. By fixing the snap-fit ​​buckle 405 to the inside of the snap-fit ​​block 404, the protective door 403 is prevented from being accidentally opened when working at height. The adjustment assembly includes a bracket 501, a threaded rod 502, a fixing rod 503, and a motor 504. The brackets 501 are fixedly connected to the four corners above the work platform 102. A threaded rod 502 is provided above a set of brackets 501, and a motor 504 is provided inside the brackets 501. The motor 504 and the threaded rod 502 are connected to the upper corners of the work platform 102. The bracket 502 is connected to the other brackets 501, which are equipped with fixed rods 503. The adjustment assembly also includes a second sliding block 505, a first guardrail 506, and a second guardrail 507.

The second guardrail 507 is slidably connected inside the first guardrail 506. The second guardrail 507 is fixedly connected to the second sliding block 505. The motor 4 504 drives the second sliding block 505 to move above the threaded rod 3 502 and the fixed rod 503. The movement of the second sliding block 505 causes the second guardrail 507 to slide out from inside the first guardrail 506. The height of the second guardrail 507 can be adjusted according to the different heights of the workers to prevent falls when working at heights.

[0024] During operation, the device is moved to the desired position using the casters 201. The hydraulic push rod 203 is then used to push the support base plate 204 downwards. When the support base plate 204 contacts the ground, the casters 201 disengage, thus fixing the device to the ground and preventing displacement. The starting motor 301 drives the threaded rod 302 to rotate, which in turn moves the sliding block 304. As the moving block 107 moves towards the fixed block 303, it causes the telescopic rod 305 to extend upwards, raising the work platform 102 and allowing for height adjustment. The starting motor 504 drives the sliding block 505 to move above the threaded rod 502 and the fixed rod 503. This movement of the sliding block 505 causes the guardrail 507 to slide out from inside the guardrail 506. The height of the guardrail 507 can be adjusted according to the worker's height to prevent falls while working at height.

[0025] Through the above steps, starting motor 2 drives the rotating roller 112 to rotate, and the rotation of the rotating roller 112 causes the rain curtain 113 to unfold from the rotating roller 112. Moving the sliding frame 110 causes the rain curtain 113 to slide in the opposite direction to the rotating roller 112, thus unfolding the rain curtain 113. By inserting the locking block 114 into the locking slot 116, the rain curtain 113 is fixed above the connecting frame 115. Starting motor 103 drives the threaded rod 104 to rotate, and the rotation of the threaded rod 104 causes the moving block 107 to move linearly above the threaded rod 104 and the sliding rod 105, so that the rain curtain 113 can be adjusted to a suitable position according to different heights. By controlling motor 2 to rotate the rotating roller 112 in the opposite direction, the reverse rotation of the rotating roller 112 causes the rain curtain 113 to move in the direction of the rotating roller 112, making it convenient to unfold and fold the rain curtain 113, which is convenient for staff to use.
