Description

Technical Field

[0001] The invention 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 door frame welding technology used in wind turbine tower manufacturing. This technology involves the use of specific welding equipment and processes to ensure the precise manufacture and installation of the door frame. The door frame welding of wind tower projects is manual welding and double-sided welding. Therefore, the welders need to stand above the tower to operate the outer weld of the wind tower door frame. The risk of slipping and falling of welders is very high, so safety protection tooling needs to be designed to ensure the safety of welders.

[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, but 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 they climb 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 the workers are 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, and the workers' working area is limited, which not only increases the difficulty of the workers' work, but also increases the risk of falling. 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 to the wind tower first and then build it, which also results in the builders having no safety protection and being prone to the risk of falling first, and the materials need to be transported up little by little, which undoubtedly increases the difficulty of the workers' work. Summary of the invention

[0004] 1. Technical issues to be resolved In view of 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, the risk of workers accidentally falling is greatly reduced; the device is easy to assemble, and can be hoisted and installed after being assembled on the ground, thereby reducing the injury rate of workers and reducing the workload of workers. It solves the problems of workers having too many tools and equipment, which increases the burden of workers crawling; tools are too messy to be deployed, which easily causes troubles to workers' movement; workers have a limited working area, and working directly on the wind tower will increase the difficulty of construction for workers, and will also increase the risk of accidental falling; 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.

[0005] (II) Technical solution In order to achieve the above-mentioned purpose of wind tower door frame welding safety protection, the present invention provides the following technical solutions: a wind tower door frame welding safety protection tooling, including a first fixer, a first threaded hole is opened on the front side of the first fixer, a first bolt is threadedly connected to the inner wall of the first threaded hole, the first fixer is threadedly connected to a reinforcing rib through the first bolt, a second threaded hole is opened on the front side of the reinforcing rib, a second bolt is threadedly connected to the inner wall of the second threaded hole, and the reinforcing rib is threadedly connected to the second fixer through the second bolt.

[0006] Preferably, a third threaded hole is formed on the side of the first and second fixers, a third bolt is threadedly connected to the inner wall of the third threaded hole, and the first and second fixers are threadedly connected to the supporting leg fixer via the third bolt.

[0007] Preferably, a supporting foot is fixedly connected to the front side of the supporting foot fixture, a first hole is formed on the top of the supporting foot fixture, and the first hole, the first fixture and the second fixture are adapted to each other.

[0008] Preferably, a side surface of the first fixture is fixedly connected to a positioning workbench, the first fixture is fixedly connected to the second fixture via the positioning workbench, and an inner wall of the positioning workbench is fixedly connected to a welding workbench.

[0009] Preferably, a fourth threaded hole is opened on the top of the positioning workbench, a fourth bolt is threadedly connected to the inner wall of the fourth threaded hole, and the positioning workbench is threadedly connected to the rest platform through the fourth bolt.

[0010] Preferably, the bottom of the rest platform is fixedly connected to a first threaded hole base, a fifth threaded hole is opened on the side of the threaded hole base, the inner wall of the fifth threaded hole is threadedly connected to a fifth bolt, and the threaded hole base is threadedly connected to an oblique support rod through the fifth bolt.

[0011] Preferably, a sixth threaded hole is opened on the side of the oblique support rod, the inner wall of the sixth threaded hole is threadedly connected with a sixth bolt, the oblique support rod is threadedly connected to a second threaded hole base through the sixth bolt, and the top of the second threaded hole base is fixedly connected to a positioning workbench.

[0012] Preferably, a threaded sleeve is fixedly connected to the top of the positioning workbench, a threaded column is threadedly connected to the inner wall of the threaded sleeve, and a vertical pole is fixedly connected to the top of the threaded column.

[0013] Preferably, a first object hanger and a second object hanger are fixedly connected to the side surface of the vertical pole in sequence from the top, a second hole is opened on the top of the first object hanger, and a chain ring is installed on the inner wall of the second hole.

[0014] Preferably, a chain is installed on the inner wall of the chain ring, a hole base is installed on the chain ring through the chain, and a tool bag is fixedly connected to the bottom of the hole base.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a wind tower door frame welding safety protection tooling, which has the following beneficial effects: 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 weight of the workers climbing. When the workers climb to the top of the wind tower, because the welding tools are stored and organized, the workers can take the corresponding tools they need, so that the work area will not become chaotic. This ensures the safety of the workers' movement in the work area to a certain extent and makes the workers' movement more convenient.

[0016] 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, so that workers have enough 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 carried out 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 accidents by the workers.

[0017] 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 are no longer required 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
