Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, and in particular to a retractable high-altitude integrated steel structure with limit and fall prevention function. Background Technology

[0002] In the field of high-altitude operations, such as the construction of large bridges, the maintenance of power facilities, or the construction of building exterior walls, large steel structures are often used as temporary load-bearing platforms or support frames. In order to adapt to the height or span requirements of different work points, telescopic steel structures have been widely used.

[0003] Currently, these types of telescopic steel structures typically rely on telescopic sleeves for fixing with bolts or pins. While this method allows for length adjustment, its safety and reliability face challenges in the complex environment of high-altitude operations.

[0004] High-altitude environments are often accompanied by strong wind loads and mechanical vibrations. Traditional bolted connections or single-point pin locking structures are prone to gaps or loosening under continuous dynamic loads, causing the telescopic parts to sway, affecting the stability of the work platform and posing safety hazards. Moreover, these conventional telescopic steel structures generally lack integrated passive safety systems. Once the main locking mechanism fails due to an accident, or the structure is subjected to a sudden strong impact, the entire telescopic part may suddenly fall or tilt. Due to the lack of effective buffering and attitude correction mechanisms, such sudden instability often directly leads to catastrophic accidents.

[0005] Therefore, this utility model proposes a retractable high-altitude integrated steel structure with limiting and anti-fall function to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems that existing retractable high-altitude connected steel structures have, such as unreliable locking mechanisms that are prone to loosening in dynamic environments, and the lack of integrated buffering and attitude correction functions in case of accidental falls, this utility model aims to provide a retractable high-altitude connected steel structure with limit and fall prevention functions that has been improved to effectively solve the above problems.

[0007] This utility model provides a retractable high-altitude integrated steel structure with limiting and fall-prevention functions, including an integrated steel body and a telescopic rod. The integrated steel body has a sliding groove, and the telescopic rod slidably engages within the groove. The structure also includes a limiting mechanism and a fall-prevention mechanism. The limiting mechanism includes an insertion hole on the integrated steel body, an insertion port on the telescopic rod corresponding to the insertion hole, and a limiting plate. The limiting plate is structured to pass through the insertion hole and be inserted into the insertion port. The fall-prevention mechanism includes a fall-prevention beam, a steel plate, a spring rod, a steel cable, and a fall-prevention disc. The fall-prevention beam is fixedly connected to the integrated steel body. The steel plate is fixed to the integrated steel body and has a through hole. The spring rod passes through the through hole of the steel plate, and one end is supported by the steel plate. One end of the steel cable is connected to the fall-prevention beam, and the other end passes sequentially through the through hole of the steel plate and the spring rod, and is fixedly connected to the fall-prevention disc.

[0008] Preferably, the retractable high-altitude integrated steel structure with limit and anti-fall function further includes a fixing screw, which is threadedly connected to the integrated steel structure, and the end of the fixing screw is adapted to abut against the outer wall of the telescopic rod, and the axis of the fixing screw is set perpendicular to the sliding direction of the telescopic rod.

[0009] Preferably, the retractable high-altitude integrated steel structure with limiting and anti-fall function further includes multiple reinforcing ribs, which are welded to the outer surface of the integrated steel structure and are spaced apart along the length of the integrated steel structure.

[0010] Preferably, the end of the spring rod supported by the steel plate has a flange edge with a diameter larger than the through hole of the steel plate, and the flange edge abuts against one side of the steel plate, thereby forming a reliable axial limit and support.

[0011] Preferably, the insertion hole is located at the top of the integral steel body.

[0012] Preferably, the fall arresting beam is arranged laterally at the rear of the continuous steel structure, and there are two steel cables, which are respectively connected to the two ends of the fall arresting beam to form a symmetrical tension structure.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model solves the problems of existing telescopic steel structures having a single locking method, being prone to loosening due to vibration, and having unreliable positioning by setting a limiting insert plate that passes through the insertion hole and is inserted into the insertion port to form a rigid positioning, while cooperating with fixing screws to tighten the threads to eliminate gaps. It achieves the technical effect of double locking, stable connection, and safety and reliability.

[0015] 2. This utility model solves the problem that existing high-altitude steel structures lack a buffer mechanism and are easily damaged by rigid impacts when they fall accidentally by setting up a linkage anti-fall mechanism consisting of an anti-fall beam, steel cable, spring rod, anti-fall disc and steel plate. It achieves the technical effect of effectively absorbing impact energy by utilizing the elastic deformation of the spring rod in the event of an accident and providing buffer protection for the main structure.

[0016] 3. This utility model solves the problem of traditional structures lacking active correction ability after tilting by using the restoring elastic force generated by the spring rod after absorbing impact energy, which acts in the opposite direction on the continuous steel through the steel cable and the anti-fall beam. It achieves the technical effect of assisting in correcting the structure's posture and improving the stability of high-altitude operations. Attached Figure Description

[0023] 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.

[0024] Please refer to Figures 1 to 4This utility model provides a retractable high-altitude integrated steel structure with limiting and anti-fall function, which aims to solve the problems of insufficient connection reliability due to the single telescopic locking structure in the prior art, and the lack of an integrated buffer anti-fall mechanism.

[0025] like Figure 1 and Figure 2 As shown, the retractable high-altitude integrated steel structure includes a continuous steel body 1 with a groove 2 on it. The telescopic rod 3 slides within the groove 2 of the continuous steel body 1. The structure also includes a limiting mechanism and a fall protection mechanism. The limiting mechanism is used to reliably position the telescopic rod 3 during extension and retraction, while the fall protection mechanism provides cushioning and attitude correction in case of an accident. The limiting mechanism includes a hole 5 on the continuous steel body 1, a socket 4 on the telescopic rod 3 corresponding to the hole 5, and a limiting plate 6. When the telescopic rod 3 slides to a predetermined position, the limiting plate 6 is designed to pass through the hole 5 and be inserted into the socket 4, forming a stable rigid connection. In a specific embodiment, the hole 5 is located at the top of the continuous steel body 1, and the fall protection mechanism includes a fixed connection to the continuous steel body. The system comprises a fall arresting beam 7, a steel plate 13 fixed to the main steel 1 and having a through hole thereon, a spring rod 9, a steel cable 8, and a fall arresting disc 10. The spring rod 9 passes through the through hole of the steel plate 13, and one end of the spring rod 9 is supported by the steel plate 13. To ensure the stability of the support, the end of the spring rod 9 supported by the steel plate 13 has a flange edge with a diameter larger than the through hole of the steel plate 13. The flange edge directly abuts against one side of the steel plate 13. One end of the steel cable 8 is connected to the fall arresting beam 7, and the other end passes through the through hole of the steel plate 13 and the spring rod 9 in sequence, and is finally fixedly connected to the fall arresting disc 10. In a preferred embodiment, the fall arresting beam 7 is arranged laterally at the rear of the main steel 1, and there are two steel cables 8, which are respectively connected to the two ends of the fall arresting beam 7.

[0026] To further improve the locking reliability of the telescopic structure and strengthen the overall frame strength, the telescopic high-altitude integrated steel structure also includes fixing screws 11 and multiple reinforcing ribs 12. Furthermore, the fixing screws 11 and reinforcing ribs 12 form specific structural fits and connections with the aforementioned integrated steel 1 and telescopic rod 3, respectively.

[0027] Please refer to the following carefully. Figure 1 The core structure will be described in detail below:

[0028] To achieve dual locking, the fixing screw 11 is threadedly connected to the integral steel 1. The axis of the fixing screw 11 is set perpendicular to the sliding direction of the telescopic rod 3, and its end abuts against the outer wall of the telescopic rod 3. After the main positioning is completed by the limiting plate 6, the fixing screw 11 is tightened so that its end applies pressure to the outer wall of the telescopic rod 3, which can effectively eliminate any potential fit gap between the telescopic rod 3 and the slide groove 2. This dual fixing method, consisting of the insertion locking of the limiting plate 6 and the abutment locking of the fixing screw 11, ensures the high stability of the telescopic structure under stress or vibration conditions.

[0029] Meanwhile, in order to enhance the load-bearing capacity of the main steel 1, multiple reinforcing ribs 12 are welded to the outer surface of the main steel 1. Specifically, multiple reinforcing ribs 12 are distributed at intervals along the length of the main steel 1. This structural layout can effectively distribute the concentrated load acting on the surface of the main steel 1 to the entire frame, significantly improving the bending and deformation resistance of the main steel 1, thereby strengthening the structural strength and safety of the entire device.

[0030] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0031] In a preferred embodiment, in order to achieve stable axial support for the spring rod 9 and prevent it from coming off under stress, the end of the spring rod 9 supported by the steel plate 13 has a flange edge with a diameter larger than the through hole of the steel plate 13. The flange edge directly abuts against one side surface of the steel plate 13 in the assembled state, thereby forming a reliable one-way limiting and supporting surface.

[0032] As another preferred embodiment, in order to facilitate the operation of the limiting insert 6 and ensure the smoothness of its insertion action, the insertion hole 5 is specifically opened on the top of the integral steel 1, which allows the operator to easily insert the limiting insert 6 from top to bottom.

[0033] In another preferred embodiment, in order to ensure the symmetrical force distribution and smooth operation of the fall arrest mechanism, the fall arrest beam 7 is arranged laterally at the rear of the connecting steel 1, and there are two steel cables 8, which are respectively fixedly connected to the left and right ends of the fall arrest beam 7, thereby forming a balanced tension system.

[0034] The working principle of this utility model of a retractable high-altitude integrated steel structure with limiting and fall-prevention function is as follows:

[0035] When the working length of the telescopic high-altitude integrated steel structure needs to be adjusted, the telescopic rod 3 slides axially within the groove 2 of the integrated steel 1. After the telescopic rod 3 slides to the target position, the operator inserts the limiting plate 6 through the insertion hole 5 on the top of the integrated steel 1 and into the insertion port 4 on the telescopic rod 3. At this time, the limiting plate 6 forms a rigid mechanical lock. Subsequently, the fixing screw 11 threaded onto the integrated steel 1 is tightened so that the end of the fixing screw 11 abuts against the outer wall of the telescopic rod 3. Through the insertion of the limiting plate 6 and the abutment of the fixing screw 11, the stability and reliability of the connection between the telescopic rod 3 and the integrated steel 1 are ensured. Throughout the load-bearing process, the multiple reinforcing ribs 12 welded to the outer surface of the integrated steel 1 continuously provide the integrated steel 1 with bending resistance.

[0036] When the structure experiences an unexpected fall or tilt while operating at height, the fall arrest mechanism is activated. The fall arrestor plate 10 uses its own weight to pull the steel cable 8, which in turn transmits the tension to the spring rod 9. Since the spring rod 9 passes through the steel plate 13, which is fixed to the connecting steel 1 and has through holes, and one end of the spring rod 9 is supported by the steel plate 13, the tension forces the spring rod 9 to undergo elastic deformation. During the deformation process, the spring rod 9 absorbs the impact energy from the fall. At the same time, the elastic force generated by the spring rod 9 recovering its deformation is transmitted in the opposite direction through the steel cable 8 to the fall arrestor beam 7, which is fixed to the connecting steel 1. This elastic force acts on the connecting steel 1 to help correct the tilting posture of the structure. The steel plate 13 provides stable axial support for the spring rod 9 during the stress process.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
