Description
Technical Field
[0001] This utility model relates to the field of steel structure climbing frame technology, and in particular to a steel structure climbing frame with a fall protection structure. Background Technology
[0002] Steel structure aerial work platforms are temporary high-altitude work platforms built with high-strength steel. They are modular, have high load-bearing capacity, and are easy to assemble and disassemble. The main body consists of columns, crossbars, diagonal braces, and other components connected by bolts or fasteners to form a stable frame structure. The surface is covered with anti-slip treads and equipped with safety railings. They are widely used in construction, equipment installation, maintenance and testing, and other fields to provide safe and reliable vertical transportation channels and working spaces for personnel and materials.
[0003] Existing steel structure climbing frames are usually used in conjunction with ladders. Workers need to climb the ladders by hand to reach the work platform. Due to the lack of stable anti-slip measures on the ladders, coupled with the possible wind interference or inconvenience of carrying tools when working at heights, it is very easy to fall due to slipping or loss of balance during the climbing process, which poses a serious safety hazard.
[0004] Therefore, in view of the problem that existing steel structure climbing frames are usually used in conjunction with ladders, and workers are prone to falling while climbing to the climbing frame, a steel structure climbing frame with a fall protection structure can be designed. Utility Model Content
[0005] To overcome the problem that existing steel structure climbing frames are usually used in conjunction with ladders, workers climb the frames using ladders, which poses a risk of falling during the climb.
[0006] The technical solution of this utility model is as follows: a steel structure climbing frame with a fall protection structure, including a climbing ladder; it also includes a baffle. An installation groove is provided on the right side of the climbing ladder. A sliding column is fixed inside the installation groove. Multiple positioning seats are fixed on the front and rear sides of the installation groove at equal intervals. Two installation holes are provided on the inner side of the positioning seats. A rotating shaft is provided between the two installation holes. Both ends of the rotating shaft are fitted with torsion springs. The rotating shaft is rotatably connected to the positioning seats through the torsion springs. A baffle is fixed on the outer side of the rotating shaft. The edge of the baffle has a chamfered structure. A positioning mechanism is provided on the front side of the climbing ladder. A stabilizing mechanism is provided on the support rod of the climbing ladder.
[0007] Preferably, by setting up a sliding column, workers attach the safety buckle of their safety rope to the outside of the sliding column while climbing. During the upward climb, the safety buckle moves up the sliding column. Each time it passes a baffle, it causes the baffle to rotate around the pivot, allowing the buckle to pass smoothly through the baffle. After passing the baffle, the torsion spring releases its elastic restoring force, causing the baffle to rotate in the opposite direction until the baffle is in contact with the upper surface of the positioning seat. In the event of an accidental fall, the safety buckle slides down the sliding column. When passing a baffle, the positioning seat limits the safety buckle, thus preventing a fall. This solves the problem that existing steel structure climbing frames are usually used in conjunction with ladders, and workers climbing to the climbing frame via ladders are prone to falling during the climb.
[0008] Preferably, the positioning mechanism includes a fall arrestor and a limiting component. The fall arrestor is used to prevent workers from falling while climbing, and the limiting component is used to limit the fall arrestor.
[0009] Preferably, the fall arrestor includes a slide groove on the front side of the climbing ladder, the inside of the slide groove having several equally spaced ratchet grooves, a slide block slidably connected inside the slide groove, spring pieces on both the left and right sides of the slide block, and a hanging ring fixed to the top of the slide block.
[0010] Preferably, a positioning plate is provided on the front side of the climbing ladder corresponding to the position of the slide groove. The front side of the positioning plate has a through groove, and the four corners of the front side of the positioning plate are connected with fixing bolts. The positioning plate is fixedly connected to the climbing ladder by fixing bolts.
[0011] Preferably, the stabilizing mechanism includes an anti-slip component and a fixing component. The anti-slip component is used to increase the friction between the climbing ladder and the worker's shoes, and the fixing component is used to position the worker's feet.
[0012] Preferably, the anti-slip component includes a sleeve fitted onto the climbing ladder support bar, the surface of which has several raised dots, which can effectively increase friction when in contact with the sole of the shoe.
[0013] Preferably, the fixing assembly includes two positioning hoops fixed to each support of the climbing ladder, and the positioning hoops are arc-shaped.
[0014] The beneficial effects of this utility model are:
[0015] Through the innovative combination of torsion spring and baffle, a one-way rotation locking function is achieved, providing reliable safety for workers at height. The baffle's unique one-way rotation characteristic can quickly capture and lock the safety buckle, effectively preventing accidental slippage and ensuring that the protection mechanism is triggered immediately when the worker loses stability, greatly reducing the risk of falling from height. The device is highly responsive and can automatically complete positioning and locking without manual intervention, improving work efficiency while ensuring safety. It is especially suitable for high-altitude work scenarios that require frequent movement. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment: a steel structure climbing frame with a fall protection structure, including a climbing ladder 1; it also includes a baffle 8. A mounting groove 2 is provided on the right side of the climbing ladder 1, and a sliding column 3 is fixed inside the mounting groove 2. Multiple equally spaced positioning seats 4 are fixed on the front and rear sides of the mounting groove 2. Two mounting holes 5 are provided on the inner side of each positioning seat 4, and a rotating shaft 6 is provided between the two mounting holes 5. Torsion springs 7 are fitted at both ends of the rotating shaft 6, and the rotating shaft 6 is rotatably connected to the positioning seats 4 through the torsion springs 7. A baffle 8 is fixed on the outer side of the rotating shaft 6, and the edge of the baffle 8 has a chamfered structure. A positioning mechanism is installed on the front side of the climbing ladder 1, and a stabilizing mechanism is installed on the support rod of the climbing ladder 1. The structure of the sliding column 3 is adopted. When the worker climbs, the safety buckle of the safety rope is put on the outside of the sliding column 3. During the climbing process, the safety buckle moves up along the sliding column 3. When it passes the baffle 8, it will push the baffle 8 to rotate around the pivot 6 to ensure that the safety buckle passes smoothly. After passing, the torsion spring 7 releases the elastic restoring force to make the baffle 8 return to its original position and fit against the upper surface of the positioning seat 4. When a fall occurs, the falling safety buckle contacts the baffle 8. At this time, the baffle 8 is limited by the positioning seat 4 to form a mechanical block, thereby realizing the fall protection function.
[0024] Please see Figure 1 and Figure 5 In this embodiment, the positioning mechanism includes a fall protection component and a limiting component. The fall protection component is used to prevent workers from falling while climbing, and the limiting component is used to limit the fall protection component. The fall protection component includes a slide groove 91 opened on the front side of the climbing ladder 1. The slide groove 91 has a plurality of equally spaced ratchet grooves 92. A slide block 93 is slidably connected inside the slide groove 91. Spring pieces 94 are provided on both the left and right sides of the slide block 93. A hanging ring 95 is fixed to the top of the slide block 93. By setting the slide groove 91, when climbing upward, the slide block 93 moves upward along the slide groove 91, and the spring pieces 94 on its surface will be compressed and contracted. Each time it moves to the position of a ratchet groove 92, the spring pieces... 94 will spring back and engage inside the ratchet groove 92, thus positioning the slide 93. Workers can attach the mounting buckle to the hanging ring 95 to assist in preventing falls during climbing. A positioning plate 96 is provided on the front side of the climbing ladder 1, corresponding to the position of the slide groove 91. A through groove 97 is opened on the front side of the positioning plate 96, and fixing bolts 98 are connected to the four corners of the front side of the positioning plate 96. The positioning plate 96 is fixedly connected to the climbing ladder 1 through the fixing bolts 98. By setting the positioning plate 96, the slide 93 can be positioned to prevent the slide 93 from falling out of the slide groove 91. The safety buckle can pass through the through groove 97 and be fixed to the hanging ring 95 without affecting the normal movement of the slide 93.
[0025] Please see Figure 1In this embodiment, the stabilizing mechanism includes an anti-slip component and a fixing component. The anti-slip component is used to increase the friction between the climbing ladder 1 and the sole of the worker's shoes. The fixing component is used to position the worker's feet. The anti-slip component includes a protective sleeve 101 fitted onto the support rod of the climbing ladder 1. The surface of the protective sleeve 101 is provided with several protrusions. When the protrusions on the surface of the protective sleeve 101 come into contact with the sole of the shoe, they can effectively increase the friction. By setting the protective sleeve 101, the protective sleeve 101 can be made of silicone, which can effectively increase the friction. The fixing component includes two positioning clamps 102 fixed on each support rod of the climbing ladder 1. The positioning clamps 102 are arc-shaped. By setting the positioning clamps 102, the worker's feet can be limited, improving the safety during climbing.
[0026] When climbing, the safety buckle of the safety rope is attached to the sliding post 3 in the mounting slot 2 on the right side of the climbing ladder 1. As you climb upwards, the safety buckle moves upwards along the sliding post 3. Each time it passes a baffle 8, the safety buckle pushes the baffle 8 to rotate around the pivot 6. At this time, the torsion springs 7 at both ends of the pivot 6 are twisted, causing the baffle 8 to move aside to allow the safety buckle to pass. After the safety buckle passes, the torsion springs 7 release their elastic restoring force, causing the baffle 8 to rotate in the opposite direction and return to its original position until the chamfered structure of the edge of the baffle 8 is in contact with the upper surface of the positioning seat 4 and is limited. If a fall occurs, the safety buckle slides down along the sliding post 3, and the baffle 8 is blocked by the positioning seat 4 and cannot rotate. Its right-angled edge will lock the safety buckle to form a rigid barrier, achieving the fall prevention function. At the same time, the worker can attach another safety buckle to... When climbing upwards, the slide 93 moves upwards along the slide groove 91 on the front side of the climbing ladder 1 on the hanging ring 95 at the top of the slide 93. The spring pieces 94 on both sides of the slide 93 are compressed and contracted. When the slide 93 moves to the position of the ratchet groove 92, the spring pieces 94 rebound and engage with the ratchet groove 92 to achieve progressive positioning. The positioning plate 96 is fixed to the front side of the climbing ladder 1 by fixing bolts 98. Its through groove 97 ensures that the safety buckle is connected to the hanging ring 95 and prevents the slide 93 from falling out of the slide groove 91. During the climbing process, the worker's feet step on the protective sleeve 101 of the support rod of the climbing ladder 1. The protrusions on the surface of the protective sleeve 101 increase the friction of the shoe sole. At the same time, the feet are limited by the arc-shaped positioning clamps 102 on the two support rods to prevent side slipping and further improve stability.
[0027] Through the above steps, when workers climb, the safety buckle of their safety rope is always on the outside of the sliding column 3. During the ascent, the safety buckle will contact each layer of baffle 8 in sequence. The lateral force applied when passing through causes the baffle 8 to rotate around the pivot 6. At this time, the torsion spring 7 stores energy. When the safety buckle has completely passed through, the torsion spring 7 releases energy, causing the baffle 8 to rebound quickly until it is tightly attached to the positioning seat 4. If a fall occurs, the falling safety buckle will hit the baffle 8. Since the baffle 8 has been limited by the positioning seat 4 and cannot continue to rotate, a reliable mechanical stop is formed, which effectively prevents a fall. This solves the problem that existing steel structure climbing frames are usually used in conjunction with ladders, and workers climb the climbing frame by ladders, which can easily lead to a fall during the climbing process.
