Description

Technical Field

[0001] This invention relates to the field of bridge steel structure construction equipment technology, specifically to a road and bridge steel structure coating equipment. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components or parts are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in bridges and other fields.

[0003] Steel structures are prone to corrosion, and steel structures on bridges need to be coated with anti-rust paint during construction. Currently, when painting the steel structures of road and bridges, workers generally use brushes to apply the paint to the surface of the steel structure. Since workers need to switch back and forth between the paint bucket and the steel structure, this not only increases the workload of the workers but also results in low work efficiency.

[0004] After steel structures are painted, the paint needs to dry before they can be used. In the existing technology, the paint is dried by natural air drying, which is a slow drying process. Summary of the Invention

[0042] Furthermore, the model number of the PLC controller 513 is CPM1A-10CDR-A-V1.

[0043] One specific embodiment of the present invention is as follows:

[0044] In operation, the paint is first added to the paint chamber 12 through the adding tube 14, such as... Figure 10 As shown, the first motor 23, pump body 32, resistance heating plate 42 and second motor 512 are powered by the control switch 514.

[0045] When the first motor 23 is working, it drives the conveyor wheel 22 and the conveyor belt 27 to rotate. Controlling the direction of the first motor 23 causes the conveyor belt 27 to rotate clockwise, lowering the steel pipe A to be coated from the left side of the equipment. The two ends of the steel pipe A are placed on the mounting base 21 and slide onto the conveyor belt 27 through the inclined surface on the left side of the mounting base 21. The conveyor belt 27 causes the steel pipe A to move from left to right.

[0046] When the pump body 32 is working, it draws the paint from the paint chamber 12 through the inlet pipe 34 and sprays it out through the outlet pipe 35, the spray pipe 31 and the nozzle 33 to act on the steel pipe A, thereby spraying the steel pipe A with paint. After being sprayed, the steel pipe A moves to the bottom of the hot air pipe 4.

[0047] like Figure 1 As shown, when the equipment is working, it also drives the drive wheel 49 to rotate, and under the action of the belt 410, the transmission wheel 48 rotates, as shown. Figure 9 As shown, the wind shaft 46 and the fan blade assembly 47 rotate, thereby allowing outside air to enter the hot air chamber 13.

[0048] like Figure 8 As shown, the air is heated by the resistance heating plate 42. Since the resistance heating plate 42 is arranged alternately in the hot air cavity 13, the air flow distance in the hot air cavity 13 can be increased, thereby improving the heating effect. The heated air is sprayed out through the hot air pipe 4 and the air outlet pipe 41, thereby drying the paint on the steel pipe A.

[0049] like Figure 5 and 6As shown, when the second motor 512 is working, it drives the drive shaft 510 and the second active bevel gear 511 to rotate, and the second driven bevel gear 59 meshing with it rotates, thereby causing the transmission shaft 56 and the first active bevel gear 57 to rotate, and the first driven bevel gear 53 meshing with it to rotate, thereby causing the swing shaft 52 and the brake plate 54 to rotate.

[0050] like Figure 10 As shown, by setting a counter, the second motor 512 is made to rotate intermittently, and the swing shaft 52 and brake plate 54 are made to rotate intermittently 360°, that is, the swing shaft 52 and brake plate 54 brake for a certain period of time for each rotation.

[0051] like Figure 7 As shown, the direction of the two swing plates is indicated by the arrows. In the initial state, the brake plate 54 faces forward and backward. When the steel pipe A comes into contact with the brake plate 54, the steel pipe A remains stationary for a certain period of time. During the process of the swing plate rotating one revolution to reset, the steel pipe A moves.

[0052] like Figure 3 As shown, when steel pipe A stops under the action of brake plate 54, steel pipe A rotates under the action of conveyor belt 27, and steel pipe A at each position is sprayed and dried respectively, making the spraying and drying operations more comprehensive.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
