Description

Technical Field

[0001] This utility model relates to the field of operating platform technology, and in particular to an operating platform for steel space frame members. Background Technology

[0002] Large-span steel space frames are the mainstream structure for modern large-space buildings. With their characteristics of light weight, uniform spatial stress, and excellent seismic performance, they have become the core choice for the roofs of buildings such as stadiums, convention centers, and high-clearance factories. These types of buildings often require open interior spaces without columns. Steel space frames can cover spans of tens or even hundreds of meters while reducing the load on the main structure of the building. The members of this type of structure are mostly suspended in the air and arranged in a dispersed manner.

[0003] Traditional steel space frame member operating platforms are mostly designed with fixed-size bearing surfaces, which means that the platform can only be adapted to a single working area. When different positions of steel space frame members or a large working area need to be handled, the entire platform must be moved frequently. High-altitude movement is not only cumbersome to operate, but also increases the stability risk due to repeated posture adjustments. At the same time, the space of the fixed bearing surface is limited, making it difficult to accommodate multiple workers, forcing the work to be carried out in stages, which is less safe. Therefore, it is necessary to propose a steel space frame member operating platform. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the need to frequently move the entire platform when handling different positions of steel space frame members or large working surfaces. High-altitude movement is not only cumbersome to operate, but also increases stability risks due to repeated posture adjustments. At the same time, the space of the fixed bearing surface is limited, making it difficult to accommodate multiple workers. Therefore, a steel space frame member operating platform is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An operating platform for steel space frame members, installed on the steel space frame members, includes: an I-shaped support frame, the I-shaped support frame being mounted on the steel space frame members;

[0007] An inclined rod and a first i-shaped guardrail are provided on the i-shaped support frame, and a limit pulley and an auxiliary rotating shaft are installed on the i-shaped support frame;

[0008] A first load-bearing plate is fixedly connected to the bottom inner side of the first C-shaped guardrail;

[0009] An electric telescopic pole, which is fixedly connected to the inner side of the first C-shaped guardrail;

[0010] The second load-bearing plate is fixedly connected to the telescopic end of the electric telescopic rod;

[0011] The second load-bearing plate is fixedly connected to a second C-shaped guardrail at the end away from the electric telescopic rod, and the second C-shaped guardrail is slidably connected to the inner side of the first C-shaped guardrail.

[0012] The above technical solution further includes:

[0013] Specifically, a limiting pulley is fixedly connected to the C-shaped support frame, and the limiting pulley is in rolling connection with the steel grid frame member.

[0014] Specifically, an auxiliary rotating shaft is rotatably connected to the C-shaped support frame, and the auxiliary rotating shaft is rollingly connected to the steel space frame member.

[0015] Specifically, the first zigzag guardrail is provided with a sliding groove, and the second load-bearing plate is slidably connected to the sliding groove.

[0016] Specifically, the two ends of the inclined rod are fixedly connected to the C-shaped support frame and the first C-shaped guardrail, respectively.

[0017] Specifically, at least two limiting pulleys are provided, and multiple limiting pulleys are symmetrically and movably connected to the inner side of the C-shaped support frame.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the symmetrically distributed limiting pulleys and auxiliary rotating shafts form a multi-point rolling bearing, which, together with the rigid support constructed by the inclined rod, ensures that the first C-shaped guardrail maintains structural stability during the spatial expansion process, making it highly practical.

[0020] 2. In this utility model, when the electric telescopic rod drives the second load-bearing plate to extend and retract along the sliding groove, the sliding groove guides and prevents deviation, so that the expansion of the second load-bearing plate is stable and controllable, and simultaneously drives the second C-shaped guardrail to slide, ensuring that the second C-shaped guardrail and the first C-shaped guardrail always form an enclosing structure, which can ensure personnel safety and accommodate multiple workers, and has strong practicality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] like Figures 1-8 As shown, the present invention proposes a steel space frame rod operation platform, which is installed on the steel space frame rod 1, including: an inverted support frame 2, which is mounted on the steel space frame rod 1;

[0033] An inclined rod 3 and a first incline guardrail 4 are provided on the incline support frame 2. A limit pulley 201 and an auxiliary rotating shaft 202 are installed on the incline support frame 2.

[0034] The first load-bearing plate 5 is fixedly connected to the bottom inner side of the first C-shaped guardrail 4;

[0035] Electric telescopic rod 6, which is fixedly connected to the inner side of the first C-shaped guardrail 4;

[0036] The second load-bearing plate 7 is fixedly connected to the telescopic end of the electric telescopic rod 6.

[0037] The second load-bearing plate 7 is fixedly connected to the end away from the electric telescopic rod 6 with a second C-shaped guardrail 8, and the second C-shaped guardrail 8 is slidably connected to the inner side of the first C-shaped guardrail 4.

[0038] Furthermore, when the steel grid frame member operating platform is in operation, the C-shaped support frame 2 is first mounted on the steel grid frame member 1 via the limiting pulley 201 and auxiliary rotating shaft 202. The tilting rod 3 helps to stabilize the support structure of the first C-shaped guardrail 4. The operator can first stand on the first load-bearing plate 5 to carry out basic work. When it is necessary to expand the operating space, the electric telescopic rod 6 is activated. Its telescopic end will push the second load-bearing plate 7 to move. At the same time, the second load-bearing plate 7 drives the second C-shaped guardrail 8 to slide along the inner side of the first C-shaped guardrail 4, which not only expands the operating load-bearing area, but also forms a safety protection barrier through the first C-shaped guardrail 4 and the second C-shaped guardrail 8. The limiting pulley 201 can also help the platform adjust the working position along the steel grid frame member 1.

[0039] A limiting pulley 201 is fixedly connected to the C-shaped support frame 2, and the limiting pulley 201 is tumbling connected to the steel grid member 1.

[0040] Furthermore, during the process of mounting the operating platform onto the steel space frame member 1, the limiting pulley 201 on the U-shaped support frame 2 will come into contact with the steel space frame member 1. With the help of the rolling cooperation, the platform can be adjusted to the target working position more smoothly along the steel space frame member 1, and the mounting position of the platform on the steel space frame member 1 can be limited, reducing the risk of platform deviation and falling off, and improving the stability and ease of operation when the platform and the steel space frame member 1 are in cooperation.

[0041] An auxiliary rotating shaft 202 is rotatably connected to the C-shaped support frame 2, and the auxiliary rotating shaft 202 is rollingly connected to the steel space frame member 1.

[0042] Furthermore, when the operating platform moves along the steel space frame member 1 or adjusts its working position, the auxiliary rotating shaft 202 on the U-shaped support frame 2 forms a rolling contact with the steel space frame member 1. This not only works with the limiting pulley 201 to further reduce the frictional resistance between the platform and the steel space frame member 1, making the platform move or turn more smoothly, but also helps to share the platform's own weight and working load, enhancing the platform's support and balance on the steel space frame member 1.

[0043] The first C-shaped guardrail 4 has a sliding groove 401, and the second load-bearing plate 7 is slidably connected to the sliding groove 401.

[0044] Furthermore, when the electric telescopic rod 6 drives the second load-bearing plate 7 to extend and retract to expand the operating space, the sliding groove 401 on the first C-shaped guardrail 4 provides a stable sliding guide path for the second load-bearing plate 7. This not only restricts the movement trajectory of the second load-bearing plate 7 and prevents it from deviating or shaking, but also reduces the frictional resistance during the movement, making the extension and retraction of the second load-bearing plate 7 smoother. At the same time, in conjunction with the protective function of the second C-shaped guardrail 8, it ensures the safety and stability of the workers when working on the expanded load-bearing surface.

[0045] The two ends of the inclined rod 3 are fixedly connected to the C-shaped support frame 2 and the first C-shaped guardrail 4, respectively.

[0046] Furthermore, during the entire operation process after the platform is mounted on the steel grid member 1, the inclined rod 3 forms a rigid whole with the C-shaped support frame 2 and the first C-shaped guardrail 4 through the fixed connection at both ends. This not only stably transmits the load generated by the first C-shaped guardrail 4, the first load-bearing plate 5, and the workers and tools to the C-shaped support frame 2 and finally to the steel grid member 1, but also enhances the deformation resistance of the connection between the two through the inclined support structure.

[0047] At least two limiting pulleys 201 are provided, and multiple limiting pulleys 201 are symmetrically and movably connected to the inner side of the U-shaped support frame 2.

[0048] Furthermore, during the entire process of the platform being mounted onto the steel space frame member 1 and moving and adjusting along it, at least two limiting pulleys 201 symmetrically arranged on the inner side of the C-shaped support frame 2 form rolling contact with the steel space frame member 1. During the mounting stage, the C-shaped support frame 2 can be made to fit against the steel space frame member 1 through the symmetrically distributed contact points.

[0049] In this embodiment, the specific implementation method is as follows: when the steel grid member operating platform is working, the C-shaped support frame 2 first forms rolling contact with the steel grid member 1 through at least two limiting pulleys 201 symmetrically and movably connected on its inner side and an auxiliary rotating shaft 202 rotatably connected. The auxiliary rotating shaft 202 enhances the support balance. At the same time, the tilting rod 3 fixes the C-shaped support frame 2 and the first C-shaped guardrail 4 to form a rigid whole, stably transmitting the first C-shaped guardrail 4 and the first load-bearing plate 5.

[0050] Workers can first stand on the first load-bearing plate 5 and use the first C-shaped guardrail 4 to form basic protection for their work. When it is necessary to expand the operating space, the electric telescopic rod 6 fixed to the inside of the first C-shaped guardrail 4 is activated. Its telescopic end pushes the second load-bearing plate 7 to slide smoothly along the sliding groove 401 on the first C-shaped guardrail 4. The sliding groove 401 limits the trajectory and reduces resistance. At the same time, the second load-bearing plate 7 drives the second C-shaped guardrail 8 fixed at its end to slide synchronously along the inside of the first C-shaped guardrail 4, forming an expanded bearing surface and a double protective barrier. When it is necessary to adjust the working position later, the limiting pulley 201 and the auxiliary rotating shaft 202 cooperate again to reduce the movement resistance, ensuring that the platform moves smoothly and stably along the steel grid member 1, ensuring structural stability and work safety throughout the process.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
