[0027] The utility model provides an embodiment:

[0028] like Figures 1 to 8 As shown, a high-altitude working platform for use on steel beams of a steel structure comprises a hanging basket frame, a supporting rod 2, a telescopic rod 3 and a supporting mechanism; the hanging basket frame is placed between two steel beams and has a hanger 1.1 with through grooves on both sides of the upper end, and a plurality of transversely arranged supporting rods 2 pass through the hanger 1.1 and are fixedly connected to the lower end surface of the upper longitudinal rod of the hanger 1.1; the telescopic rod 3 is slidably connected to the two ends of the supporting rod 2 and can be locked, and a limiting plate 4 for abutting against the inner side surface of the steel beam is provided on the telescopic rod 3, and the supporting mechanism is connected below the outer end of the telescopic rod 3 and abuts against the upper horizontal surface of the steel beam.

[0029] In this embodiment, the hanging basket frame includes a hanger 1.1, a supporting frame 1.2, a base plate 1.3 and a protective fence 1.4; the base plate 1.3 covers the bottom surface of the supporting frame 1.2, the protective fence 1.4 extends upward around the outer peripheral edge of the supporting frame 1.2, and two longitudinal hangers 1.1 are fixedly connected to the upper end of the protective fence.

[0030] The support rod 2 is a hollow tube, and a part of the telescopic rod 3 is slidably connected in the inner cavity of the support rod 2 and can be locked by a compression screw 5 threadedly connected to the end of the support rod 2. A limit ring 6 is fixedly connected in the inner cavity of the end of the support rod 2, and the limit ring 6 has a hole for the compression screw 5 to pass through. The end of the telescopic rod 3 located in the inner cavity of the support rod 2 is provided with a baffle 7 that cooperates with the limit ring 6 to prevent the telescopic rod 3 from slipping out of the support rod 2.

[0031] The upper part of the limit plate 4 has an annular sleeve that is slidably connected to the telescopic rod 3. The annular sleeve is locked on the telescopic rod 3 by a clamping screw 5 threadedly connected thereto. The positions of the telescopic rod 3 and the limit plate 4 are adjusted according to the spacing between the two parallel steel beams, so that the two limit plates 4 on both sides of the support rod 2 are respectively abutted against the inner end of a steel beam, ensuring that the hanging basket frame will not slide sideways with the movement of the support roller 8.1.

[0032] The supporting mechanism includes a supporting roller 8.1 and a U-shaped wheel frame 8.2, the supporting roller 8.1 is rotatably connected to the U-shaped wheel frame 8.2, the upper end of the U-shaped wheel frame 8.2 is fixedly connected to the telescopic rod 3, the supporting roller 8.1 abuts against the upper horizontal surface of the steel beam and can be locked by a clamping screw 5 threadedly connected to the telescopic rod 3, the lower end of the clamping screw 5 can pass through the U-shaped wheel frame 8.2 and be clamped on the supporting roller 8.1 to avoid sliding of the device caused by a slight tilt of the steel beam.

The fence frame is arranged around the guardrail. The bottom plate 1.3 is a corrugated steel plate with a continuous trapezoidal cross section, which has a higher bearing strength. The corner connection of the hanging basket frame is welded with right-angle ribs, which is more stable as a whole. The hanger 1.1, the support frame 1.2, the fence frame of the protective fence 1.4 and the support rod 2 are all welded and formed by square tubes, and the four are welded and formed as one.

[0034] Specific steps:

[0035] Assemble and weld the hanging basket frame and the supporting rod 2, adjust the extension of the telescopic rod 3 according to the distance between the two steel beams, so that the supporting rollers 8.1 on both sides of any supporting rod 2 can respectively abut against the upper end of the horizontal plane of the corresponding steel beam, and lock the telescopic rod 3 on the supporting rod 2 by the compression screw 5;

[0036] The whole device is hoisted between two steel beams, and the limit plate 4 is slid to make it abut against the inner end of the steel beam, and then locked on the telescopic rod 3 by the compression screw 5. The support roller 8.1 is compressed and limited by the compression screw 5 to complete the installation of the device.

[0037] When the whole device needs to be moved again, the whole device can be driven to move along the length of the steel beam by the support roller 8.1 until the construction within the above two steel beams is completed.
