[0024] The embodiment of the present application provides an external anti-rust spraying device for a steel support. Due to the use of a clamping component, the steel parts can be effectively fixed under the interaction of a hollow cylinder, a fastening bolt and a flexible pressing plate. Then, by using a cleaning component, the impurities on the surface of the steel parts can be effectively removed under the interaction of components such as a rust removal plate, a bidirectional screw rod, a second spring, a limit rod and a buffer rod, and then the paint treatment is performed. Therefore, it effectively solves the technical problem that when the existing spraying device sprays the steel support structure, the steel support structure needs to be turned over in order to spray its back side. This process is relatively cumbersome, wastes manpower and time, and is not practical.

[0025] Example 1

[0026] The technical solution in the embodiment of the present application is to effectively solve the technical problem that when the existing spraying device sprays the steel support structure, the steel support structure needs to be turned over to spray the back side thereof, which is a cumbersome process and wastes manpower and time. The overall idea is as follows:

[0027] In response to the problems existing in the prior art, the utility model provides a steel-supported external anti-rust spraying device including a workbench 2, a bracket 3 fixedly installed on the top of which, a pillar 1 welded to the bottom of the workbench 2, two protrusions 31 fixed to the bottom of the bracket 3, and two fixed blocks 32 fixed to the top of the workbench 2 near the two protrusions 31, which are fixedly installed on one side of the protrusion 31, one end of the drive motor 41 is transmission-connected to a reciprocating screw 410, the surface of the reciprocating screw 410 is threadedly connected to a cleaning assembly 4, and the two fixed blocks 32 are internally movably connected to a clamping assembly 5.

[0028] In some examples, the clamping assembly 5 includes two hollow cylinders 51, wherein a connecting rod 54 is fixed to one end of the left hollow cylinder 51, and a first spring 55 is arranged around the surface of the connecting rod 54. A rotating shaft 414 is fixed to one end of the right hollow cylinder 51. The tops of the two hollow cylinders 51 are threadedly connected with fastening bolts 52, and a flexible pressing sheet 53 is fixed to the bottom of the fastening bolts 52. Figure 1-4 As shown, first, one end of the steel piece is placed inside the left hollow cylinder 51, and then the hollow cylinder 51 is squeezed. Under the action of the connecting rod 54, the hollow cylinder 51 is translated to the left, and the first spring 55 is squeezed at this time. Then the other end of the steel structure can be placed inside the right hollow cylinder 51. At this time, the fastening bolt 52 is rotated to make the flexible pressing piece 53 below it close to the steel piece, and the steel piece can be fixed. The connecting rod 54 and the rotating shaft 414 are connected to the fixing block 32 through the bearing, as shown in FIG. Figure 5 As shown, the bearing can reduce the friction between the connecting rod 54 and the fixed block 32, thereby extending the service life thereof.

[0029] In some examples, the cleaning assembly 4 includes a U-shaped plate 42, the middle of the U-shaped plate 42 is connected to a bidirectional screw rod 43 through a bearing, a rotating cap 44 is fixed to one side of the bidirectional screw rod 43, the surface of the bidirectional screw rod 43 is threadedly connected to two movable plates 45, one side of the two movable plates 45 is fixed to a limiting rod 461, the middle of the bidirectional screw rod 43 is rotatably connected to a connecting block 61 through a bearing, a paint spray interface 6 is fixed above the connecting block 61, and a nozzle 62 is fixedly installed below the connecting block 61, such as Figure 1-4 As shown, rotating the rotating cap 44 drives the bidirectional screw 43 to rotate, and under the action of the limiting rod 461, the bidirectional screw 43 drives the two movable plates 45 on the surface to move toward each other until the rust removal plate 46 contacts the steel part and squeezes the second spring 463, which can effectively remove impurities on the surface of the steel part. The internal movability of the movable plate 45 is connected to a plurality of buffer rods 462, one end of each of the plurality of buffer rods 462 is fixedly connected to the rust removal plate 46, and the surface of the plurality of buffer rods 462 is surrounded by a second spring 463, as shown in FIG. Figure 3 As shown, the buffer rod 462 and the second spring 463 are used. The elasticity of the second spring 463 can make the rust removal plate 46 more fully contact with the steel part, thereby improving the effect of removing impurities.

[0030] During the specific implementation process, when it is necessary to paint the steel support structure, first place one end of the steel part into the left hollow cylinder 51, and then squeeze the hollow cylinder 51. Under the action of the connecting rod 54, the hollow cylinder 51 is translated to the left, and the first spring 55 is squeezed at this time. Then the other end of the steel structure can be placed into the right hollow cylinder 51. At this time, the fastening bolt 52 is rotated to make the flexible pressing piece 53 below it close to the steel part, and the steel part can be fixed. The rotating cap 44 is rotated to drive the bidirectional screw rod 43 to rotate. Under the action of the limiting rod 461, the bidirectional screw rod 43 drives the two movable plates 45 on the surface to move toward each other until the rust removal plate 46 contacts the steel part and squeezes the second spring 463. At this time, the rotating cap 44 is stopped, and the drive motor 41 is turned on to drive the reciprocating screw rod 410 to rotate, and the U-shaped plate 42 is Under the restriction of the guide rod 415, it moves back and forth along the surface of the reciprocating screw rod 410. At this time, the rotation of the active pulley 411 drives the belt 412 to rotate, thereby rotating the driven pulley 413, and the driven pulley 413 drives the rotating shaft 414 to rotate. The rotating shaft 414 drives the hollow cylinder 51 to rotate, thereby rotating the steel part. At this time, the rust removal plate 46 moves back and forth along the surface of the steel part driven by the U-shaped plate 42. With the help of the rotation of the steel part, the impurities on the surface of the steel part can be effectively removed, which is convenient for subsequent painting treatment. After removing the impurities on the surface, turn off the drive motor 41, rotate the rotating cap 44 in the opposite direction to move the rust removal plate 46 away from the steel part, connect the paint interface 6, turn on the drive motor 41 and turn on the nozzle 62 switch at the same time, so that the paint can be evenly sprayed on the steel part to complete the rust prevention of the steel support structure.

[0031] Example 2

[0032] Based on Example 1, this embodiment of the present application is a feasible technical solution for an external anti-rust spray device for a steel support. The overall idea is as follows:

[0033] In some examples, a guide rod 415 is fixed between the protrusions 31, a driving pulley 411 is fixedly installed on the right side of the reciprocating screw 410, a driven pulley 413 is fixedly installed on one end of the rotating shaft 414, and a belt 412 is connected between the driving pulley 411 and the driven pulley 413. Figure 2 As shown, the driving pulley 411 rotates to drive the belt 412 to rotate, thereby rotating the driven pulley 413, the driven pulley 413 drives the rotating shaft 414 to rotate, and the rotating shaft 414 drives the hollow cylinder 51 to rotate, thereby rotating the steel part. The wrap angle between the driving pulley 411 and the driven pulley 413 and the belt 412 is 150 degrees. Figure 2 As shown, setting the wrap angle to 150 degrees can make the belt 412 more fully contact with the driving pulley 411 and the driven pulley 413, preventing slippage during the transmission process and affecting the transmission efficiency.
