[0002] At present, the inverted installation method is widely used in the production and installation of large steel tanks. Its characteristics are that it works at low altitude and does not require the establishment of high-altitude platforms. Installation, splicing, welding, and inspection are all completed on the ground. It is a more convenient construction method. When steel tanks are working on the ground, the installation of wall panels is an important task of the main project except for the top cover and bottom plate. The wall panels are generally loaded by cranes extending around the storage tanks. If the site is narrow, the foundation spacing is small, and the car crane cannot enter, the loading of the wall panels of the steel tank will become very difficult.

[0053] In a preferred embodiment of the present invention, the support mechanism 102, the walking mechanism 103 and the lifting mechanism 104 are connected as a whole through the truss mechanism 101, and a remote control device is used to control the walking and lifting of the tank wall panel feeding device 100. When the diameter of the steel storage tank 200 changes, the retractable truss mechanism 101 can determine the length of the truss according to the radius of the tank.

[0054] Further, the truss mechanism 101 is telescopically movable and can extend 300 mm to 500 mm beyond the edge of the steel storage tank 200.

When the telescopic rod is extended along the horizontal plane, the cross bar 1013 is extended along the groove structure; when the telescopic rod is shortened along the horizontal plane, the cross bar 1013 is shortened along the groove structure.

Similarly, the pawls and ratchets can also cooperate to realize the truss mechanism 101. At the same time, the trouble of opening grooves and installing pulleys is also eliminated. In addition, it is also eliminated to fix and space multiple resilient fixed blocks in the opened grooves, further saving labor costs and time costs.

[0064] It is to be understood that the grooves and pulleys, ratchets and pawls described above are not limited to those described above.
