[0026] In order to achieve the above-mentioned purpose and effect, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0027] like Figure 1-3 As shown, the present invention provides a non-corbel special-shaped steel column hanging welding operation platform, comprising an assembled walkway 1, a guardrail 2 and a triangular support frame 3, wherein the triangular support frame 3 is fixedly mounted at the bottom of the assembled walkway 1, the guardrail 2 is mounted on one side of the assembled walkway 1, a bracket ear 5 is mounted on one side of the steel column 4, and the two ends of the triangular support frame 3 away from the assembled walkway 1 are respectively connected to the steel column 4 and the bracket ear 5. The assembled walkway 1 is provided with two, respectively located on both sides of the steel column 4.

[0028] A steel springboard 6 is set up between the two assembled walkways 1 to facilitate the passage of workers. Two safety ropes 7 are synchronously pulled at both ends of the two oppositely arranged guardrails 2 to improve the safety of the operation.

[0029] In this embodiment, the side of the guardrail 2 opposite to the triangular support frame 3 is connected with a limiting card plate 8, and the limiting card plate 8 fixed on the guardrail 2 and the limiting card plates 8 fixed on the upper and lower sides of the triangular support frame 3 form a fixing groove adapted to the assembled walkway 1, and the assembled walkway 1 is clamped by the limiting card plate 8. The assembled walkway 1 is stably clamped by the limiting card plate 8, thereby ensuring the stability of the installation of the assembled walkway 1.

[0030] In this embodiment, a steel ladder 10 is installed on the steel column 4, and a fall arrester 9 is installed on the steel column 4 on one side of the ladder. The steel ladder 10 is convenient for operators to go up and down the operating platform after the operating platform is set up. When climbing the steel ladder 10, the operators tie the safety rope 7 of the fall arrester 9 to their bodies to avoid the risk of accidental falling, thereby improving the safety of personal protection.

[0031] refer to Figure 4 In this embodiment, the fabricated walkway 1 includes a plurality of fabricated panels 11, and adjacent fabricated panels 11 are rotatably connected via a damping shaft 12. The fabricated walkway also includes a bolt assembly 13, one end of the fabricated panel is connected to a plug-in block 14, and the other end is provided with a plug-in slot adapted to the plug-in block. After the plug-in blocks 14 of adjacent fabricated panels are inserted into the plug-in slot, they are locked by the bolt assembly 13. The number of fabricated panels 11 can be reasonably adjusted according to demand, and the setting of the damping shaft can realize the folding placement of the fabricated walkway 1 and reduce the occupied space on the ground; when unfolded, a certain force can be generated to prevent the fabricated walkway 1 from folding, thereby facilitating the installation of the bolt assembly 13.

[0032] This embodiment also provides a method for installing a non-corbel special-shaped steel column hanging type welding operation platform, comprising the following steps:

[0033] Step S1, in order to facilitate the workers to go up and down after the operation platform is set up, the steel ladder 10 can be hung on the side of the steel column 4, and the 12mm thick bracket ear 5 can be welded on the top of the steel column 4 through the steel ladder 10 hung in advance;

[0034] Step S2, according to the height distance between the lifting lug and the two columns, the hanging triangular support frame 3 is welded on the ground and assembled with the assembled walkway 1 and the 1.2m guardrail to form a whole, and fixed firmly with the limit card plate 8; wherein the hanging triangular support frame 3 is made of L75*6 or L100*6 angle steel;

[0035] Step S3, using a tower crane to hoist the assembled temporary operating platform as a whole to the top of the steel column 4 for installation through the hoisting holes set in advance on the limit card plate 8, and fastening it to the steel column 4 and the bracket ear 5 with bolts;

[0036] Step S4, after the assembled walkways 1 on both sides are installed, tightened and stabilized, two safety ropes 7 are synchronously pulled at both ends of the two oppositely arranged guardrails 2; and a steel springboard 6 is set up between the two assembled walkways 1; wherein the two safety ropes 7 are both made of 9mm steel wire rope.

[0037] The present invention sets a bracket hanging ear 5 on the top of the steel column 4, and after the hanging triangular support frame 3 is welded and manufactured, it is assembled with the assembled walkway 1 and the guardrail into a whole, and temporarily fixed by the limit card plate 8 on the triangular support frame 3, thereby realizing the stable placement of the standardized steel column 4 platform. If the cross-sectional dimension of the steel column 4 is too short, a steel springboard 6 can be set up to form a temporary passage to ensure the stability of the platform. The installation process of the top of the steel column 4 is adopted to provide an effective welding operation space for the special-shaped steel column 4 without a corbel.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
