A welding fixture for steel structure railings

Abstract

This utility model discloses a welding fixture for steel structure railings, relating to the field of steel structure processing technology. The utility model includes an operating platform, a support structure, a positioning device, and hoisting equipment. By designing a fixture composed of 20mm thick steel plates, round pipes or H-beams for support, L100×8 positioning angle steel, and a half-arm crane, this utility model changes the traditional assembly and turning methods. Operators can directly assemble and weld using the angle steel positioning, eliminating the need for frequent reference to drawings and measurements. After welding on one side, the fixture can be quickly turned over to continue work. Finished products can be stacked on the platform and transported in batches via the half-arm crane. This fixture is simple to manufacture, low in cost, and can be adapted to different specifications of railings by changing the position of the angle steel. It requires low technical skills from operators, eliminating the need for riveters and requiring only low-level welders. This significantly reduces measurement and turning time, greatly improving the per capita production efficiency of railing manufacturing while saving labor costs.

Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular relates to a welding fixture for steel structure railings. Background Technology

[0002] In stadiums, train stations, and other architectural structures, a large number of railings are required, most of which are made of round tubes with a diameter of less than 100mm. Existing conventional railing manufacturing processes have significant drawbacks: the round tubes are cut with a cutting machine, dimensions are measured manually, and assembly and welding are performed on the ground or a workbench. This traditional method results in a cumbersome manufacturing process, low per capita output, and severely impacts production efficiency and output.

[0003] To address the aforementioned issues, we propose a welding fixture for steel structure railings. Utility Model Content

[0004] The purpose of this utility model is to provide a welding fixture for steel structure railings, which solves the problem of low processing efficiency of steel structure stadium railings. By designing special fixtures, it enables the efficient production of large batches of round tube railings.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a welding fixture for steel structure railings, comprising an operating platform, a supporting structure, a positioning device, and a hoisting device; the operating platform is made of 20mm thick steel plate and has dimensions of 2m×10m; the supporting structure uses round pipes or H-beams to support the operating platform; the positioning device is an L100×8 angle steel and is installed on the operating platform; the hoisting device is a half-arm crane and is used in conjunction with the fixture.

[0007] In one embodiment, the operating platform includes a platform a and a platform b, which are integrated in a "V" shape. Platform a is used for assembling and welding railings, and platform b is used for stacking finished railings.

[0008] In one embodiment, the position of the angle steel of the positioning device can be adjusted according to the specifications of the railing, and it is fixed to the operating platform by spot welding. The positioning angle steel is provided on both sides of the operating platform for positioning welding after the railing is turned over.

[0009] In one embodiment, the support structure is welded and fixed to the operating platform to form a stable inclined support structure.

[0010] In one embodiment, the half-arm crane is installed on one side of the operating platform for batch transfer of finished railing products.

[0011] In one embodiment, both platform a and platform b are designed to be inclined at a 30° angle to the ground, so that the railings are in close contact with the positioning angle steel under the action of gravity, reducing the need for manual straightening.

[0012] This utility model has the following beneficial effects:

[0013] This utility model designs a fixture consisting of a 20mm thick steel plate (2m×10m, inclined at 30° to the ground), round pipe or H-beam support, L100×8 positioning angle steel, and a half-arm crane. This fixture changes the traditional assembly and turning method. Operators can directly assemble and weld using the angle steel positioning, without frequently referring to drawings and taking measurements. After welding on one side, it can be quickly turned over to continue working. The platform b can be used to stack finished products and transport them in batches via the half-arm crane. This fixture is simple to manufacture, low in cost, and can be adapted to different specifications of railings by changing the position of the angle steel. It requires low technical skills from operators, eliminating the need for riveting and requiring only low-level welders. It significantly reduces measurement and turning time, greatly improves the per capita production efficiency of railing manufacturing, and saves labor costs.
