Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to an adjustable enclosed steel structure welding operation platform. Background Technology

[0002] Steel structure welding operation platforms are indispensable auxiliary facilities in the manufacturing and installation of steel structures. They provide a safe and stable working environment for welding operations, ensuring welding quality and efficiency. With the widespread application of steel structures in construction, bridges, ships, and other fields, the demand for welding operation platforms is increasing daily.

[0003] A search revealed Chinese patent CN211647390U, which discloses a novel steel structure installation and welding operation platform. The platform includes a support structure located on a giant column, a base plate structure, a shielding structure, and a top structure. The shielding structure is arranged around the base plate structure. The base plate structure includes a base plate frame and a support plate. The shielding structure includes a shielding frame and a first shielding plate connected to the shielding frame and used to close the perimeter of the giant column. The top structure includes a top frame and a second shielding plate connected to the top frame and used to close the top frame.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] While the aforementioned patents can achieve a certain degree of closed welding, they cannot be adjusted according to the size of different steel structures. At present, conventional steel structure welding operation platforms are generally manufactured on-site and reused, with relatively uniform and fixed dimensions, resulting in poor practicality and thus certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes an adjustable enclosed steel structure welding operation platform, which can be adjusted according to the size of different steel structures, thereby achieving a fully enclosed welding method at the bottom, greatly improving the efficiency and stability of welding.

[0007] The technical solution to achieve the purpose of this utility model is as follows: an adjustable enclosed steel structure welding operation platform, including a supporting keel, an enclosure keel fixedly installed on the outside of the supporting keel, a pair of supporting door panels rotatably installed on one side of the supporting keel via a hinge, a plurality of patterned steel plates I and a pair of patterned steel plates II fixedly installed on the supporting keel and the supporting door panels respectively, a pair of enclosure door panels rotatably installed on one side of the enclosure keel via a movable shaft, and also including an enclosure component.

[0008] The enclosure components are installed on the supporting keel and the supporting door leaf.

[0009] The interior of the supporting keel is provided with a second keel groove and a pair of first keel grooves, and each of the supporting door panels is provided with a door panel groove.

[0010] In some embodiments, a horizontal adjustment plate, a vertical adjustment plate, and a door leaf adjustment plate are slidably installed inside the first keel slide rail, the second keel slide rail, and the door leaf slide rail, respectively, and the horizontal adjustment plate, the vertical adjustment plate, and the door leaf adjustment plate are staggered with each other.

[0011] In some embodiments, a U-shaped pull plate is fixedly installed on one side of both the horizontal and vertical adjustment plates, and a U-shaped pull plate is fixedly installed on one side of the door adjustment plate.

[0012] In some embodiments, the inner walls on both sides of the bottom of the supporting keel are rotatably penetrated by supporting screws, and threaded cylinders are fixedly installed inside the supporting keel at the corresponding positions of the supporting screws, with the supporting screws and threaded cylinders being threadedly engaged.

[0013] In some embodiments, a support plate slides through the bottom of each of the supporting door panels, and a pair of support plates have through holes at their front ends, wherein a pair of support screws are slidably engaged with the through holes.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, this utility model, through the setting of multiple different adjustment plates, can be well adjusted according to the size of the steel structure to be welded, thereby achieving a complete enclosure of the bottom of the operating platform, avoiding gaps that could pose safety hazards to construction workers operating on it; at the same time, high-temperature sparks generated during welding can pass through the gaps and splash down to the construction surface below, easily causing personal injury and fire, thus greatly improving the safety and efficiency of the welding process.

[0016] Secondly, by providing a support screw and a support plate at the bottom, this utility model can ensure that when there are many tension adjustment plates, the support screw and support plate can provide a certain degree of support for the adjustment plates, thereby improving the stability of the adjustment plates during use and further ensuring the construction safety of construction personnel.

[0017] This solves the problem that while existing technologies can achieve a certain degree of closed welding, they cannot be adjusted according to the size of different steel structures. At present, conventional steel structure welding operation platforms are generally manufactured on-site and reused, with relatively uniform and fixed dimensions, resulting in poor practicality.

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an adjustable, enclosed steel structure welding operation platform through improvements. The technical solution of this utility model is as follows:

[0028] like Figures 1-5 As shown, an adjustable enclosed steel structure welding operation platform includes a supporting keel 1, an enclosure keel 2 fixedly installed on the outside of the supporting keel 1, a pair of supporting door panels 6 rotatably installed on one side of the supporting keel 1 via hinges, multiple patterned steel plates 4 and a pair of patterned steel plates 5 fixedly installed on the supporting keel 1 and the supporting door panels 6 respectively, and a pair of enclosure door panels 3 rotatably installed on one side of the enclosure keel 2 via a movable shaft. It also includes an enclosure assembly. The supporting keel 1 and the enclosure keel 2 form a relatively safe operating space, thereby improving the safety protection of construction personnel. The use of the patterned steel plates 4 and 5 not only meets the usage requirements of the operation platform but also greatly saves costs.

[0029] The enclosure component is installed on the supporting keel 1 and the supporting door leaf 6.

[0030] The interior of the supporting keel 1 is provided with a keel groove 2 16 and a pair of keel grooves 15, and each supporting door leaf 6 is provided with a door leaf groove 17.

[0031] Furthermore, horizontal adjustment plate 7, vertical adjustment plate 8, and door leaf adjustment plate 9 are slidably installed inside the keel slide rail 15, keel slide rail 2 16, and door leaf slide rail 17, respectively. The horizontal adjustment plate 7, vertical adjustment plate 8, and door leaf adjustment plate 9 are staggered with each other. Through the installation of the horizontal adjustment plate 7, vertical adjustment plate 8, and door leaf adjustment plate 9, adjustments can be made according to the size of the steel structure, thereby ensuring that the bottom of the operating platform can fit well against the outer wall of the steel structure to form a closed effect, thus improving the safety and efficiency of construction.

[0032] Furthermore, a U-shaped pull plate 10 is fixedly installed on one side of both the horizontal adjustment plate 7 and the vertical adjustment plate 8, and a U-shaped pull plate 21 is fixedly installed on one side of the door leaf adjustment plate 9. The U-shaped pull plate 10 and U-shaped pull plate 211 make it easy for construction workers to pull out and store the adjustment plates, greatly simplifying the operation steps.

[0033] Furthermore, support screws 12 are rotatably inserted through the inner walls of both sides of the bottom of the support keel 1. Threaded cylinders 13 are fixedly installed inside the support keel 1 at the corresponding positions of the support screws 12. The support screws 12 and the threaded cylinders 13 are threadedly engaged. The support screws 12 can provide a certain degree of support for the adjustment plate, thereby improving the stability of the adjustment plate during use.

[0034] Furthermore, a support plate 14 slides through the bottom of each supporting door leaf 6, and a pair of support plates 14 have through holes at their front ends. A pair of support screws 12 slide in the through holes. The support plates 14 can provide support for the relatively central position of the door leaf adjustment plate 9, thereby further improving the overall stability of the door leaf adjustment plate 9 and thus improving the overall safety of the device.

[0035] The specific working method is as follows: First, open the enclosure door 3 and the supporting door 6, hoist the device to the position of the steel structure to be welded, close the enclosure door 3 and the supporting door 6, and after the construction personnel enter, use the pins to fix the enclosure door 3 to prevent the enclosure door 3 from opening on its own during the welding process and causing unnecessary safety hazards. Then, according to the size of the steel structure, move out the supporting screw 12 and the supporting plate 14. After moving to the appropriate position, pull out the adjusting plate through the U-shaped pull plate 10 and the U-shaped pull plate 2 11 until it is in contact with the surface of the steel structure, thereby forming a bottom closed effect, thereby improving the safety and efficiency stability of the welding process.

[0036] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
