Technical Field

[0001] This utility model relates to the field of copper smelting technology, specifically a vertical railing lifting device for safety protection in post-furnace operations of PS copper converters. Background Technology

[0002] In the copper smelting industry, the PS copper converter is the core equipment for producing blister copper from matte. The post-furnace work area (including the operating positions around the copper tapping and slag tapping points) is the highest-risk work area in the entire smelting process. Safety protection in this area is directly related to the safety of workers and the continuity of production. Vertical guardrails, as a core component of physical isolation protection, play a decisive role in the effectiveness of protection due to their rationality and applicability.

[0003] Currently, due to space constraints, tuyer operation limitations, and frequent converter processes, fixed protective railings cannot be installed on the rear platform of PS copper converters. Therefore, temporary movable railings or rotating railings are often installed. However, temporary movable railings are difficult to install and remove frequently, while rotating railings have a high failure rate and are easily damaged by large pieces of material from above, resulting in high maintenance frequency and costs. Therefore, a vertical railing lifting device for safety protection in PS copper converter rear operations is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical guardrail lifting device for safety protection in post-furnace operations of PS copper converters, thereby solving the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model relates to a vertical guardrail lifting device for safety protection during post-furnace operations in PS copper converters, comprising: The lifting seat has hydraulic rods fixed on both sides of its top end, and connecting seats are fixed on the telescopic ends of the two hydraulic rods. A vertical guardrail is provided on the opposite side of the two connecting seats. The auxiliary limiting component includes two rotating plates, the top ends of which are respectively rotatably disposed on both sides of the bottom end of the vertical guardrail. A locking bolt is provided through one side of each of the two rotating plates and is threadedly engaged with the locking bolt.

[0005] Furthermore, vertical rods are fixedly provided on the top side of the lifting seat, and a fixing groove is provided on one side of each of the two vertical rods.

[0015] 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.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a vertical guardrail lifting device for safety protection in post-furnace operations of a PS copper converter, comprising: The lifting seat 11 has hydraulic rods 12 fixed on both sides of its top end. The telescopic ends of the two hydraulic rods 12 are fixed with connecting seats 13. The opposite sides of the two connecting seats 13 are jointly provided with vertical guardrails 14. The lifting platform 11 is installed on the adjacent wall or ground platform. The hydraulic rod 12 adopts the HSG01-80 / 50*300 model, which is used to provide the driving force required for the vertical guardrail 14 to move up and down. When the hydraulic rod 12 is in the normal state, the vertical guardrail 14 is located below the plane of the adjacent high point, and the vertical guardrail 14 is close to and attached to the adjacent wall, thus avoiding large pieces of material falling from the top and damaging the protective device.

[0018] The auxiliary limiting component includes two rotating plates 21. The top ends of the two rotating plates 21 are respectively rotatably set on both sides of the bottom end of the vertical guardrail 14. A locking bolt 22 is provided through one side of each of the two rotating plates 21 and is threadedly engaged with the locking bolt 22. The locking bolt 22 is used to limit the position of the rotating plate 21, thereby achieving auxiliary limiting and fixing of the vertical guardrail 14.

[0019] Vertical rods 15 are fixedly provided on the top side of the lifting seat 11. A fixing groove 151 is provided on one side of each of the two vertical rods 15. A slide block 16 is slidably provided on the inner wall of each of the two fixing grooves 151. One side of each slide block 16 is fixedly provided on the back of the vertical guardrail 14. The fixed groove 151, in conjunction with the sliding block 16, can assist in guiding and limiting the vertical guardrail, allowing the vertical guardrail 14 to move stably up and down along the direction of the vertical bar 15.

[0020] The top of each of the two vertical rods 15 is provided with a storage slot 153, and the top of each storage slot 153 is fitted with a cover 254. An observation window 155 is embedded on the opposite side of each of the two vertical rods 15. Storage tank 153 is used to store lubricating oil. The observation window 155 is made of transparent PVC board, which makes it easy to observe the amount of lubricating oil in storage tank 153 and to add or replenish it in a timely manner.

[0021] Two through holes 152 are provided on one side of each of the two fixing slots 151, and the through holes 152 communicate with the inside of the storage slot 153.

[0022] Working principle: When the vertical guardrail 14 is used for protection, the hydraulic rod 12 is opened. The hydraulic rod 12 drives the connecting seat 13 to move upward, which in turn drives the vertical guardrail 14 to move upward. Then, the rotating plate 21 is rotated towards the vertical rod 15 until the rotating plate 21 contacts the outer wall of the vertical rod 15. Then, the locking bolt 22 is rotated until the locking bolt 22 is tightly connected to the vertical rod 15. When protection is not used, the locking bolt 22 is opened, the rotating plate 21 is rotated to the bottom of the vertical guardrail 14, and the hydraulic rod 12 is opened again. The hydraulic rod 12 drives the vertical guardrail 14 to move and reset. In this way, the safety guardrail can be quickly raised and lowered in complex environments, solving the problems of low service life of guardrails or high labor intensity of personnel in the post-converter working environment. It also effectively reduces the frequency of post-converter guardrail maintenance and the expenditure of manpower and material resources. At the same time, when the safety guardrail is raised for protection, the auxiliary limiting component can help limit and fix the safety guardrail, thus avoiding the risk of the safety guardrail falling.

[0023] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The opening and closing component includes a crossbar 31, a movable plate 32 is slidably provided on the outer wall of the crossbar 31, and a first sealing rod 33 and a second sealing rod 34 are respectively fixed at the upper and lower ends of one side of the movable plate 32. The two ends of the crossbar 31 are fixedly installed on both sides of the storage tank 153. The first sealing rod 33 and the second sealing rod 34 are slidably connected to the two through holes 152 respectively, with one end of the first sealing rod 33 located inside the through hole 152 and one end of the second sealing rod 34 located outside the through hole 152.

[0024] The opening and closing component also includes a spring 35. The inner side of the spring 35 is sleeved on the outer wall of the crossbar 31. One end of the spring 35 is fixedly connected to the other side of the movable plate 32, and the other end of the spring 35 is fixedly connected to one side of the storage groove 153.

[0025] The end of the second sealing rod 34 is semi-circular, and the length of the second sealing rod 34 is longer than the length of the first sealing rod 33; When the end of the second sealing rod 34 is on the same vertical plane as the inner side of the fixing groove 151, the end of the first sealing rod 33 is separated from the through hole 152 at its corresponding position.

[0026] Working principle: When the hydraulic rod 12 operates, it drives the vertical guardrail 14 to move up and down. The vertical guardrail 14 moves up and down, which in turn drives the slide 16 to move up and down. When the slide 16 moves to contact the second sealing rod 34, it will drive the second sealing rod 34 to move inward. The inward movement of the second sealing rod 34 will compress the spring 35 through the moving plate 32, and at the same time drive the first sealing rod 33 to move inward until the first sealing rod 33 separates from the corresponding through hole 152. At this time, the lubricating oil in the storage tank 153 flows from the through hole to the fixed groove 151. When the slide 16 moves to separate from the second sealing rod 34, the spring 35 will cause the moving plate 32 to move in the opposite direction, so that the first sealing rod 33 will block the through hole 152 again. At this time, the lubricating oil in the storage tank 153 will stop flowing out. In this way, self-lubrication can be performed while driving the safety guardrail to rise and fall, thereby reducing the friction between the slide 16 and the fixed groove 151 and improving the smoothness of the safety guardrail's rise and fall.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
