Description
Technical Field
[0001] The utility model relates to the technical field of wind tower door frame welding safety protection, in particular to a wind tower door frame welding safety protection tooling. Background Art
[0002] Wind tower door frame welding is a technique used in wind turbine tower manufacturing. This technique involves the use of specialized welding equipment and processes to ensure precise door frame fabrication and installation. However, door frame welding for wind tower projects is manual and double-sided. Therefore, welders must stand above the tower to weld the outer seams of the door frame. This poses a high risk of slipping and falling, necessitating the design of safety gear to ensure welder safety.
[0003] The door frame welding of the existing wind tower project is done by manual welding between the door frame parts on the wind tower. However, manual welding directly on the wind tower is too dangerous. Workers need to carry a large number of welding tools when welding, which will increase the weight of the workers when climbing up the wind tower. When the complicated tools are spread out on the wind tower, it will also affect the movement of the workers. Secondly, when welding the door frame of the wind tower project, the workers stand directly on the wind tower. There is no area around the wind tower body for workers to weld. The workers' working area is limited, which not only increases the difficulty of the workers' work, but also increases the risk of falls. The existing wind tower door frame welding safety protection is basically a temporary protection built on the wind tower, and the disassembly and assembly of the existing temporary protection requires workers to go up the wind tower first and then build it. This also causes the builders to have no safety protection and are prone to the risk of falling first. In addition, the materials need to be transported up bit by bit, which undoubtedly increases the difficulty of the workers' work. Utility Model Content
[0004] (1) Technical problems solved
[0005] In response to the deficiencies in the prior art, the present invention provides a wind tower door frame welding safety protection tooling, which has a device that can carry most of the welding materials by itself, and the welding materials and tools can be manually sorted and hung for storage, which is convenient for workers to move. The device has a sufficient operating area so that workers can work with peace of mind, and at the same time greatly reduces the risk of workers accidentally falling. The device is easy to assemble and can be hoisted and installed after being assembled on the ground, which reduces the injury rate of workers and reduces the workload of workers. It solves the problems of workers having too many tools and equipment, which increases the burden of workers crawling, tools being too messy and easily causing trouble for workers' movement, and workers having a limited working area. Direct construction on the wind tower will increase the difficulty of construction for workers, and will also increase the risk of accidental falls. Most of the protection built on the wind tower is temporary, and workers need to assemble it on the wind tower in advance. This will increase the injury rate of workers without safety measures, and the transportation of construction materials will also increase the workload of workers.

[0017] (3) Beneficial effects
[0018] Compared with the existing technology, the utility model provides a wind tower door frame welding safety protection tooling, which has the following beneficial effects:
[0019] 1. The wind tower door frame welding safety protection tooling is assembled through the connection of a threaded sleeve, a threaded column, a vertical pole, a first hanger, a second hanger, a chain ring, a chain, a hole base and a tool bag, so that workers can roll up the required welding equipment in advance and store it in the tool bag and the second hanger, so that workers only need to climb directly to the wind tower through a ladder, which to a certain extent reduces the load of workers climbing. When workers climb to the top of the wind tower, because the welding tools are all stored and organized, workers can just take the corresponding tools they need, so that the work area will not become cluttered. This to a certain extent ensures the safety of workers' movement in the work area and makes workers' movement more convenient.
[0020] 2. The wind tower door frame welding safety protection tooling forms a complete workbench through the assembly and connection of the first fixture, the positioning workbench, the second fixture, the welding workbench, the fourth bolt, the rest platform, the first threaded hole base, the fifth bolt, the oblique support rod, the sixth bolt and the second threaded hole base. This allows workers to have sufficient operating area and operating space, which enables workers to construct the door frame in a stable area, which increases the workers' working area to a certain extent and reduces the difficulty of their work. At the same time, because the welding construction is not directly on the wind tower body, but on the work platform, the workers will not slip and fall because they are too absorbed in their work and fail to observe the edge of the wind tower. This ensures the personal safety of the workers to a certain extent and reduces the risk of accidental falls of the workers.
[0021] 3. The wind tower door frame welding safety protection tooling, through the assembly of the first fixer, the second fixer, the reinforcement rib, the support leg module, the workbench and the hanging device, enables the device to be assembled on the ground first, and then hoisted to the wind tower by lifting. Workers no longer need to climb up with materials before welding construction, thereby reducing the risk of accidental injuries and falls caused by workers setting up temporary protection. At the same time, it also solves the problem of increased work intensity caused by workers needing to transport materials for setting up temporary protection. BRIEF DESCRIPTION OF THE DRAWINGS
