[0013] In order to make the technical means for realizing the present invention, the creative features, the purpose and the effect easily understood, the present invention is further explained below in conjunction with specific illustrations. In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0014] Example 1

[0015] like Figures 1 to 4 As shown, an auxiliary device for positioning a large burner includes: a boom body 1, the upper end of which is provided with an external thread, a fixing nut 3 is provided on the upper end of the boom body 1, a hanging plate 4 is provided at the lower end of the boom body 1, a connecting plate 5 is provided on the hanging plate 4, and the connecting plate 5 is mounted on the hanging plate 4 via a connecting pin 6. A backing plate 2 is provided on the boom body 1 below the fixing nut 3.

[0016] Example 2

[0017] like Figures 1 to 4 As shown, an auxiliary device for positioning a large burner includes: a boom body 1, an external thread is formed on the upper end of the boom body 1, a fixing nut 3 is provided on the upper end of the boom body 1, a hanging plate 4 is provided at the lower end of the boom body 1, a connecting plate 5 is provided on the hanging plate 4, and the connecting plate 5 is mounted on the hanging plate 4 via a connecting pin 6. Connecting pin holes are provided at both ends of the connecting plate 5.

[0018] Example 3

[0019] like Figures 1 to 4 As shown, an auxiliary device for positioning a large burner includes: a boom body 1, the upper end of which is provided with an external thread, a fixing nut 3, and a hanger plate 4 at the lower end of the boom body 1. The hanger plate 4 is provided with a connecting plate 5, and the connecting plate 5 is mounted on the hanger plate 4 via a connecting pin 6. The hanger plate 4 is welded and fixed to the lower end of the boom body 1, and the hanger plate 4 is provided with a connecting pin hole.

[0020] This utility model uses a single three-piece I-beam dragway beam as a temporary shoulder beam. The lifting point center is innovatively designed to manufacture a boom device. Taking into account the deviation in the hook distance, a splint and pin are added between the boom and the burner lifting lug to eliminate these distances and smoothly insert the pin. CAD is used to accurately draw the center of the 41-meter boom of the boiler. After calculation, the boiler factory modified the extra M76x3 boom to just meet the manufacturing requirements. Considering the frequent earthquakes and typhoons in the local area, a boom hole is opened in the middle of the shoulder beam. Although there is a reinforcing rib plate, two beams are stacked to ensure safety. Two units are used for actual on-site lifting and installation. It is easy and safe to use, increases stability after being in place, and adjusts the benchmark accurately and stably. This is a very safe and practical burner installation innovation for areas prone to typhoons and earthquakes. This method can save the material and installation costs of eight sets of 50-ton pulleys, wire ropes, and burner casing reinforcements, saving the project approximately 400,000 yuan in construction costs.
