DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0029] refer to Figure 1 to Figure 3 As shown, an adjustable steel beam suspension work platform includes a suspension arm 1 and a suspension basket 2, wherein the suspension arm 1 is suspended on a steel beam 3, and the suspension basket 2 is fixed on the suspension arm 1. There are at least two suspension arms 1, and all the suspension arms 1 are used to support a suspension basket 2. The platform is preferably composed of a movable suspension basket formed by welding two sections of L-shaped steel plates and rectangular tubes, which is easy to install and disassemble.

[0030] The hanging arm 1 is a welded integral structure, and includes a wall transverse section 101, a wall vertical section 102 and a wall end section 103. The whole is made of 20mm Q325 steel plate, the steel plate is 50mm wide, the upper wall transverse section 101 is 800mm long, and the lower wall vertical section 102 is 2400mm long. The front end of the wall transverse section 101 is welded to the wall vertical section 102 to form an L-shaped structure, and the rear end of the wall transverse section 101 is connected to the wall end section 103 to form an L-shaped structure, so that the wall transverse section 101, the wall vertical section 102 and the wall end section 103 form a hook-shaped structure, which can be hung on the steel beam 3 without detachment.

[0031] A plurality of horizontal adjustment holes 104 are provided along the length direction of the wall horizontal section 101, and a plurality of vertical adjustment holes 105 are provided along the length direction of the wall vertical section 102. The two ends 150 mm away from the L-shaped corner are opened with two rows of holes at each end, and the holes are arranged alternately, with a hole diameter of 20 mm. Stirrups 106 are inserted into the horizontal adjustment holes 104 and the vertical adjustment holes 105, and the two ends of the stirrups 106 are fixed as a whole by locking hoops 107. A hoop structure is formed between the wall horizontal section 101, the wall vertical section 102 and the stirrups 106, so that the hoop structure can realize the hoop setting of the steel beam 3 and the fixation of the hanging arm 1.

[0032] During installation, the L-shaped structure formed by the wall horizontal section 101 and the wall vertical section 102 is first fitted to the upper right angle on the front side of the steel beam 3, and the short side is in contact with the attachment. The short side contact plate can effectively disperse the shear stress of the hanging arm on the I-beam to prevent stress concentration from causing damage to the I-beam. Then, one end of the stirrup 106 is passed through the horizontal section adjustment hole 104, and the stirrup 106 passes through the upper right angle on the rear side at the same time, then bypasses the lower right angle on the rear side of the steel beam 3, and then passes through the vertical section adjustment hole 105. The stirrup 106 passes through the lower right angle on the front side at the same time, and finally the two ends of the stirrup 106 are locked and fixed by the locking hoop 107. The remaining upper right angle on the front side of the steel beam 3 can be bypassed by any end of the stirrup 106. Thus, the stirrup 106 cooperates with the wall horizontal section 101 and the wall vertical section 102 to achieve the fixing of the steel beam 3. By adjusting the stirrup 106 to pass through the adjustment holes at different positions, it can be used for steel beams 3 of different sizes.

[0033] The hanging basket 2 includes a basket frame 201 and a basket bottom plate 202. The basket frame 201 is an upper opening structure, which can realize the entry and exit of personnel and materials, and a protective enclosure is formed around it. The basket bottom plate 202 is laid at the bottom of the basket frame 201 to provide a support plane for personnel and materials.

[0034] The basket frame 201 is a rectangular frame made of aluminum alloy, with a size of 2000mm×1200mm×1500mm. The whole is welded with aluminum alloy square tubes. Aluminum alloy has low density and good corrosion resistance, and is suitable for the production of light hanging basket frames. At the same time, aluminum alloy has good electrical conductivity and can effectively prevent static electricity accumulation.

[0035] The basket bottom plate 202 is made of organic glass with a thickness of 10 mm. The organic glass plate has a low density and good toughness, which can effectively reduce the deadweight of the platform. At the same time, the organic glass plate has good transparency, which can improve the vision of workers during operation.

[0036] A plurality of hanging holes 108 are provided on the vertical wall section 102, each at a spacing of 200 mm, and a hanging point 203 is provided on the basket frame 201, also at a spacing of 200 mm. The hanging point 203 is hung in the hanging hole 108 to achieve fixed installation of the hanging basket 2 on the hanging arm 1, and the hanging point 203 is hung in the hanging holes 108 at different positions to achieve vertically adjustable installation of the hanging basket 2 on the vertical wall section 102.

[0037] The hanging hole 108 is a T-shaped structure, and the hanging slot corresponds to the hanging fulcrum of the movable hanging basket. The slot is generally T-shaped, wide at the top and narrow at the bottom, so that the hanging fulcrum of the movable hanging basket can be embedded and fixed in a staggered manner.

[0038] A pull rope 109 is provided between the hanging hole 108 and the basket frame 201, and a pull ring is provided on each upper side of the front side of the hanging basket, so that the steel rope passes through, is led out from the hanging slot at the lower end of the L-shaped steel and clamped with a fastener, thereby achieving the effect of reinforcing the movable hanging basket.

[0039] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
