[0023] Embodiment 1: This embodiment is intended to help solve the problem that when welding is installed on site, due to the inability to take effective protective measures on site, the fume generated by welding may pollute the environment. Please refer to Figure 1 - Figure 4 A boiler platform and guardrail connection structure, comprising a boiler body 100, a platform 200, a guardrail 300 and an escalator 400, wherein the platform 200 is located at the side of the boiler body 100, the guardrail 300 is installed on the outside of the platform 200 and the outside of the escalator 300, and the escalator 400 is installed at the side of the platform 200, the platform 200 is composed of a channel steel frame 210 and a grid plate 220, and the grid plate 220 is installed on the channel steel frame 210, the guardrail 300 comprises a column 310, a handrail 320 and a second rod 330, the handrail 320 is installed on the upper part of the column 310, the second rod 330 is arranged in the middle of the column 310, and a locking assembly 500 is arranged between the handrail 320, the column 310 and the second rod 330;

[0024] The locking assembly 500 includes a locking ring 510 sleeved on the outside of the handrail 320, and a locking hole 511 opened in the column 310. The bottom end of the locking ring 510 is inserted into the locking groove 511. A semi-cylindrical cross nut 512 is inserted in the locking ring 510. A semi-circular head cross bolt 513 corresponding to the semi-cylindrical cross nut 512 is inserted in the locking groove 511. The front end of the semi-cylindrical cross nut 512 is threadedly inserted in the semi-circular head cross bolt 513.

[0025] The semicircular cross bolt 513 is threadedly matched with the semi-cylindrical cross nut 512, and the second rod 330 is set as an angle iron rod. The outer sleeve of the other second rod 330 is provided with a first U-shaped bolt 521 for fixing, and the first U-shaped bolt 521 is set as a U-shaped stud bolt. The first U-shaped bolt 521 is located on one side of the column 310, and the other side of the column 310 is plugged with a second long internal thread nut 520 corresponding to the first U-shaped bolt 520, and the second long internal thread nut 520 is threadedly plugged with the end of the first U-shaped bolt 521. A footboard 530 is installed on the side of the column 310, and the footboard 530 is located at the bottom of the second rod 330. The footboard 530 is clamped with a second U-shaped bolt 531 for fixing the footboard 530, and the end of the second U-shaped bolt 531 is plugged with a third long internal thread nut 532.

[0026] The semicircular cross bolt 513 is threadedly matched with the first long internal thread nut 512 through the adjustment slot 511, so that the long internal thread nut 512 can move in the adjustment hole 511. The stability and firmness of the connection are increased. The first U-shaped bolt 521 is located on one side of the column 310. This design ensures the positioning and locking of the second rod 330.

[0027] The footboard 530 is installed at the bottom of the second rod 330, and the second U-shaped bolt 531 is located outside the footboard 530 to fix the footboard 530. The end of the second U-shaped bolt 531 is plugged with a third long inner thread nut 532, in this way, the footboard 530 can be firmly fixed on the column 310.

[0028] During installation, the existing column 310 is changed into a square tube, and the handrail 320 is firmly installed by means of a semicircular cross bolt 513 and a second long internal thread nut 520, and then the semicircular cross bolt 513 is rotated clockwise so that the semicircular cross bolt 513 is threadedly matched with the adjustment groove 514 in the first half-length internal thread semicircular cross nut 512. As the semicircular cross bolt 513 moves, the locking ring 510 fixedly installed on the semicircular cross bolt 513 is driven to gather close to the first half-length internal thread semicircular cross nut 512, thereby locking the column 310 and the handrail 320.

[0029] In this embodiment: the locking ring 510 is fixedly inserted on the outside of the semi-circular head cross bolt 513, so that as the first half-length inner thread semi-circular head cross nut 512 moves, the locking ring 510 will be gathered together, thereby locking and fixing the column 310 and the handrail 320. In this way, the handrail 300 on the platform 200 does not need to be welded to ensure stability and safety, and there will be no looseness or instability during the work process. The staff can avoid the problem of on-site installation welding, which may cause the fume generated by welding to pollute the environment due to the inability to take effective protective measures on site.

[0030] Embodiment 2: This embodiment is intended to help solve the problem of deformation or looseness that may occur during use. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1 - Figure 4 .

[0031] The grid plate 220 is fixedly mounted with a mounting plate 221, which is set as an M-shaped plate. The mounting plate 221 and the channel steel frame 210 are both provided with fixing grooves 222, and the fixing grooves 222 are plugged with fixing bolts 223 corresponding to the fixing grooves 222. The grid plate 220 is fixedly mounted on the channel steel frame 210 by the fixing bolts 223 and nuts 224 corresponding to the fixing grooves 222. An integral platform is formed. The nuts 224 firmly mount the grid plate, ensuring a firm connection between the various components, thereby improving the bearing capacity and stability of the overall structure.

[0032] A drilling groove 211 is drilled on one side of the channel steel frame 210, and two third U-shaped bolts 213 are plugged outside the drilling groove 211, the channel steel frame 210 and the column 310. A reinforcing nut 521 is installed at the end of the third U-shaped bolt 213, and the reinforcing nut 521 is located inside the drilling groove 211. A groove 311 corresponding to the handrail 320 is provided on the column 310, and the handrail 320 is installed on the column 310 through the groove 311. By providing the groove 311 on the column 310 and allowing the handrail 320 to be horizontally installed on the column 310 through the groove 311, the problem of loose connection or easy looseness that may exist in the original structure is effectively solved. This design ensures a tight connection between the handrail 320 and the column 310, and improves the safety of the overall structure.

[0033] In the present embodiment, the use of the third U-bolt 213 and the reinforcement nut 521 inserted into the drilling groove 211, the channel steel frame 210 and the column 310 helps to maintain the integrity and stability of the structure, thereby effectively preventing the structure from being deformed or loosened during use, thereby improving the reliability and durability of the overall structure.
