Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a hanging basket suspension device for steel beams. Background Technology

[0002] In the field of construction engineering, suspended platforms serve as core support equipment for high-altitude operations, directly impacting construction safety and work efficiency. By stably suspending the suspended platform from the building structure, it provides a mobile operating platform for high-altitude work such as curtain wall installation and steel structure maintenance. Especially in modern large-span, high-rise building projects, it has become an indispensable infrastructure. The rationality of its structural design and its environmental adaptability not only affect construction progress but also directly relate to the safety of workers.

[0003] Existing suspended platform suspension systems typically consist of a support system and a counterweight mechanism. The front support base is rigidly fixed to the concrete floor slab or roof using chemical anchors, which maintain horizontal stability through their pull-out resistance. Concrete or cast iron counterweights are stacked at the rear support position to counteract the overturning moment generated by the load at the front of the suspended platform. When the suspended platform carries personnel and materials, the torque generated by the tension at the front is balanced by the counter-torque of the rear support counterweights, ensuring the overall stability of the suspension mechanism.

[0004] However, when the construction scenario involves special structures such as high-altitude steel structure corridors, since the main body is composed of steel beams such as H-beams and I-beams, and lacks the planar load-bearing structure of traditional floor slabs, on the one hand, the lack of floor slab foundations causes chemical anchors to lose their fixed support points, and the support base cannot be rigidly connected; on the other hand, the cross-sectional shape of the steel beams is complex, and most of them are suspended, so traditional counterweights have no supporting surface to place, making it difficult to balance the load by gravity. Utility Model Content

[0005] This invention addresses the problem of unstable load balance in steel beam structures due to the inability to securely install counterweights, by providing a suspended basket device for steel beams that achieves stable load balance without the need for counterweights.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a steel beam suspension basket device, including a support beam, a suspension basket connector installed at the front end of the support beam, a vertically arranged insertion rod fixed on the support beam, a front bracket fixed at the lower end of the insertion rod, the front bracket being able to be fixedly connected to the steel beam, at least one set of balancing components provided at the rear end of the support beam, each set of balancing components including a first connecting pipe, the first connecting pipe being fixedly connected to the rear end of the support beam, a first turnbuckle provided below the first connecting pipe, a first connecting rope connected between one end of the first turnbuckle and the first connecting pipe, and a fixing plate connected to the other end of the first turnbuckle, the fixing plate being able to be fixed to the steel beam.

[0007] In this technical solution, a front bracket is connected to the lower end of a fixed rod on the support beam, and the front bracket can be fixedly connected to the steel beam. A suspended platform hanger is installed at the front end of the support beam, and the suspended platform can be hung on the hanger. At least one set of balancing components is provided at the rear end of the support beam. Each set of balancing components includes a first connecting pipe fixedly connected to the rear end of the support beam. The first connecting pipe is connected to one end of a first turnbuckle via a first connecting rope, and the other end of the turnbuckle is connected to a fixing plate that can be fixed to the steel beam. The fixing plate applies tension to the support beam through the first connecting rope to balance the load of the suspended platform. At the same time, the length of the first connecting rope can be adjusted by the first turnbuckle, thereby precisely adjusting the balancing force. Therefore, through the above structural design, this device can achieve stable load balance without the need for counterweights.

[0008] Furthermore, the support beam comprises a front beam, a middle beam, and a rear beam, all of equal length. The middle beam is located between the front and rear beams, and its two ends are fixedly connected to the front and rear beams, respectively. The support beam is divided into three sections of equal length, each of which can be manufactured independently, avoiding the technological difficulties of forging or rolling a long beam as a whole. The middle beam, serving as the connecting hub between the front and rear beams, can be adapted to different span steel beam installation scenarios by adjusting the relative positions of the three sections.

[0009] Furthermore, a support plate is fixed to the bottom of the front support, which can be fixedly connected to the steel beam. As the interface component between the front support and the steel beam, the support plate increases the contact area and evenly distributes the load of the suspended platform to the surface of the steel beam, avoiding stress concentration caused by traditional point contact.

[0010] Furthermore, an upper support column is fixed to the upper end of the insertion rod, and a first rope sheave is rotatably connected to the upper support column. A second connecting pipe is fixed to the rear beam, and a second rope sheave is rotatably connected to the second connecting pipe. A third rope sheave is rotatably connected to the hanging basket connector. A second connecting rope is wound around the first, second, and third rope sheaves. A second turnbuckle is installed on the second connecting rope, and its two ends are fixedly connected to the two ends of the second connecting rope, respectively. The first, second, and third rope sheaves form a closed pulley system through the second connecting rope, converting the load of the hanging basket into the tension of the second connecting rope, which is then transmitted to the rear beam and the steel beam fixing point. The second turnbuckle on the second connecting rope allows for adjustment of the tension of the second connecting rope.

[0011] Furthermore, a limit rod is fixed on the rear beam, and a guide sleeve is fixed on the limit rod. The guide sleeve is fitted onto the outside of the second connecting rope. The guide sleeve is fitted onto the outside of the second connecting rope and fixed to the rear beam by the limit rod, forming a rigid constraint channel to ensure that the second connecting rope always runs along the preset path.

[0012] Furthermore, a lifting lug is installed on the fixed plate, and the lifting lug is hooked to the end of the first turnbuckle. The hook connection between the lifting lug and the first turnbuckle allows the first turnbuckle to swing automatically within a certain range. When the load direction of the basket changes or the surface of the steel beam has an inclination angle, the first turnbuckle can adjust the axial direction in real time to ensure that the tension is always transmitted axially.

[0013] Furthermore, both the first and second connecting ropes are woven from several metal ropes. The composite structure formed by the woven metal ropes enhances the resistance to breakage through a load-distribution mechanism.

[0014] Furthermore, the angle between the length direction of the first connecting pipe and the length direction of the support beam is in the range of 30-60°. When the load direction of the suspended platform changes or the surface of the steel beam has an inclination angle, the 30-60° angle itself allows the tensile force to maintain an effective component in the axial direction of the support beam, avoiding lateral force concentration caused by excessively large or small angles.

[0015] As can be seen from the above technical solution, the advantages of this utility model are as follows: In this technical solution, a plug rod is fixed on the support beam, and the front bracket connected to the lower end of the plug rod can be fixed to the steel beam. The basket hanger joint installed at the front end of the support beam is used to hang the basket. At least one set of balancing components is set at the rear end of the support beam. Each set of balancing components includes a first connecting pipe fixedly connected to the rear end of the support beam. The first connecting pipe is connected to one end of a first turnbuckle through a first connecting rope, and the other end of the first turnbuckle is connected to a fixing plate that can be fixed to the steel beam. The fixing plate applies tension to the support beam through the first connecting rope to balance the load of the basket. At the same time, the length of the first connecting rope can be adjusted by the first turnbuckle to achieve precise adjustment of the balancing force. Therefore, through the above structural design, this device can achieve stable load balance without the need for counterweights. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] A steel beam suspension device using a hanging basket, such as Figure 1 As shown, the system includes a support beam 9, with a suspended platform connector 2 installed at its front end, allowing the suspended platform to be attached to the connector 2. Vertically arranged insert rods 3 are fixed to the support beam 9, with a front support 4 fixed to the lower end of each insert rod 3. The front support 4 can be fixedly connected to the steel beam 1. At least one set of balancing components is provided at the rear end of the support beam 9, which can balance the load applied to the support beam 9 by the suspended platform.

[0024] In this specific embodiment, the support beam 9 includes a front beam 6, a middle beam 7, and a rear beam 8, all with the same length. The middle beam 7 is located between the front beam 6 and the rear beam 8, and both ends of the middle beam 7 are fixedly connected to the front beam 6 and the rear beam 8, respectively. In this embodiment, the front beam 6, the middle beam 7, and the rear beam 8 are all made of square hollow tubular profiles, and the dimensions of the front beam 6, the middle beam 7, and the rear beam 8 decrease sequentially. That is, the middle beam 7 can be inserted into the front beam 6, and the rear beam 8 can be inserted into the middle beam 7. Bolt holes are provided at the connection points of the front beam 6, the middle beam 7, and the rear beam 8, which can be fixed by bolt connection.

[0025] like Figure 2 As shown, the insertion rod 3 penetrates the front beam 6 of the support beam 9 vertically. Several bolt holes are provided on the insertion rod 3 in the vertical direction, and it is fixed to the front beam 6 by bolts. The front bracket 4 is welded to the lower end of the insertion rod 3, and the whole is in the shape of a triangular frame. A horizontally arranged support plate 19 is welded to its bottom, and the bottom surface of the support plate 19 can be welded to the steel beam 1.

[0026] A vertically arranged upper support column 5 is welded to the upper end of the insertion rod 3. A first rope wheel 17 is provided at the top of the upper support column 5, and the first rope wheel 17 is rotatably connected to the upper support column 5 via a hinge. The suspended basket hanger 2 is welded to the end of the front beam 6 away from the middle beam 7, and a third rope wheel 16 is provided on it. The third rope wheel 16 is rotatably connected to the suspended basket hanger 2 via a hinge. A second connecting pipe 13 is welded to the end of the rear beam 8 away from the middle beam 7. The length direction of the second connecting pipe 13 is inclined upward, and a second rope wheel 18 is provided at its end. The second rope wheel 18 is rotatably connected to the second connecting pipe 13 via a hinge.

[0027] A second connecting rope 10 is wound around the first winding reel 17, the second winding reel 18, and the third winding reel 16. The second connecting rope 10 is woven from several metal ropes. A second turnbuckle 12 is provided on the second connecting rope 10, and its two ends are respectively fixed to the two ends of the second connecting rope 10 by wrapping and binding. Rotating the second turnbuckle 12 can adjust the tension of the second connecting rope 10. In this embodiment, the second connecting rope 10 is made up of multiple rope segments fixedly connected by rope clamps 20, and each rope segment has an excess rope end, so the total length can be flexibly adjusted according to needs.

[0028] like Figure 3 As shown, a vertically arranged limiting rod 11 is welded on the rear beam 8. A guide sleeve 23 is welded to the upper end of the limiting rod 11. The guide sleeve 23 is sleeved on the outside of the second connecting rope 10 to form a rigid constraint channel, ensuring that the second connecting rope 10 runs along the preset path.

[0029] like Figure 4 As shown, in this specific embodiment, there are two sets of balancing components. Each set of balancing components includes a first connecting pipe 14, which is welded to the end of the rear beam 8 away from the middle beam 7. Its length direction is inclined downwards, and the angle between it and the length direction of the support beam 9 is in the range of 30-60°. A first turnbuckle 22 is provided below the first connecting pipe 14, and a first connecting rope 15 is connected between the first turnbuckle 22 and the first connecting pipe 14. The first connecting rope 15 is woven from several metal ropes. In this embodiment, the first connecting rope 15 is fixedly connected by multiple rope segments through rope clamps 20. Each rope segment has excess rope ends, which can be flexibly adjusted to adjust the total length. One end of the first connecting rope 15 is fixed to the end of the first connecting pipe 14 by wrapping and binding, and the other end is fixed to one end of the first turnbuckle 22 by wrapping and binding. The other end of the first turnbuckle 22 is hooked and connected to the lifting lug 24 on the fixing plate 21. The lifting lug 24 is welded to the fixing plate 21, and the bottom surface of the fixing plate 21 can be welded to other steel beams 1.

[0030] The specific usage process is as follows: First, insert the middle beam 7 into the front beam 6 and the rear beam 8 into the middle beam 7 according to actual needs, and fix them together with bolts. This adjusts the overall length of the support beam 9 and the position of the front bracket 4, ensuring that the front bracket 4 is accurately positioned above the steel beam 1. Next, fully weld the support plate 19 at the bottom of the front bracket 4 to the upper surface of the steel beam 1, paying attention to the operating procedures during welding to ensure a firm connection. Then, adjust the rope clamp 20 on the second connecting rope 10 to make the length of the second connecting rope 10 suitable, and then tighten the second connecting rope 10 by rotating the second turnbuckle 12. Afterwards, adjust the rope clamp 20 on the first connecting rope 15 to make the length of the first connecting rope 15 appropriate, fully weld the fixing plate 21 to the other steel beam 1, and tighten the first connecting rope 15 by rotating the first turnbuckle 22, so that the first connecting rope 15 generates tension on the rear beam 8, thereby balancing the load applied by the suspended platform. Throughout the process, attention must be paid to the accuracy and firmness of the connection of each component to ensure that the suspension device can operate stably after installation.

[0031] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: In this specific embodiment, a plug rod is fixed on the support beam, and the front bracket connected to the lower end of the plug rod can be fixed to the steel beam. A hanging basket connector installed at the front end of the support beam is used to hang the hanging basket. At least one set of balancing components is provided at the rear end of the support beam.

The fixing plate applies tension to the support beam through the first connecting rope to balance the load of the hanging basket. Simultaneously, the length of the first connecting rope can be adjusted by the first turnbuckle to achieve precise adjustment of the balancing force. Therefore, through the above structural design, this device can achieve stable load balance without the need for counterweights.
