Embodiment Construction

[0037]The jib 30 is made of section steel, the size of the section steel is 9627mm*1100mm*900mm (length, width and height when placed horizontally), and the weight is 508kg. It is used for the jib 30 on the crane. According to different types of cranes, the jib 30 The size and weight are different, but their shapes are basically the same. The above is just giving the size and weight information of one of them.

[0038] Such as Figure 1-12 Shown: a coating system for the crane jib 30 made of the above-mentioned section steel, including a pre-processing unit, a powder spraying unit and a curing unit, the pre-processing unit, the powder spraying unit and the curing unit are connected in series on the track 3, and the jib 30 passes through the track 3. Spraying is completed through the pre-processing unit, powder spraying unit and curing unit. The pre-processing unit is used for degreasing, dust removal and static electricity removal of the auxiliary arm 30; the powder spraying u...

Abstract

The invention provides a coating system for a jib of a section-steel-made crane. The coating system comprises a pretreatment unit, a powder spraying unit and a curing unit. The curing unit comprises a curing chamber for curing spraying and a second strong cooling chamber for cooling after curing. The curing chamber comprises a first chamber and a second chamber. The second chamber is arranged at the front end of the first chamber. A curing platform is arranged in the second chamber. A gas heating device is arranged in the curing platform. Electric heating devices connected in parallel are arranged on the two sides of the upper portion of the curing platform. The gas heating device and the electric heating devices are arranged to effectively complement each other, the gas heating device effectively increases the heat flow and compensates for the defects of poor heat flow and uneven heating of the electric heating devices, and the electric heating devices effectively compensate for the defects that the temperature rises slowly and the temperature is insufficient by the adoption of the gas heating device; and the heating efficiency and the heating uniformity of the jib are effectively improved, the solidification of the powder is facilitated, the generation of cracks is effectively reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of powder coating, in particular to a coating system for making crane jibs from section steel. Background technique [0002] The jib of the crane is an angle-adjustable jib attached to the head of the main jib in order to increase the operating range (height and range) of the crane. There are folding jibs and telescopic jibs according to different working methods. When not in use, it can be folded, retracted or disassembled. It is widely used, but it is especially common for outdoor use. Therefore, it is particularly important to spray the surface of the jib to protect the life of the jib and prevent rust. With the advancement and development of science and technology, however, there are higher requirements for the amount and quality of the jib, and the requirements for production equipment are also getting higher and higher. [0003] Patent No. CN 108339695 A discloses a new type of energy-saving and envir...
