Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a special jig for steel structure painting. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect between components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. Steel structures are prone to rust, and generally steel structures need to be derusted, galvanized or painted, and need to be maintained regularly. However, during the painting process of steel structure components, they often need to be placed on a stable shelf for convenient operation by workers.

[0003] After retrieval, a patent with the Chinese patent application number 202320295967.1 discloses a special jig for steel structure painting, including a telescopic support. One end of the telescopic support is fixedly connected with an installation plate. A through hole is opened at the center of the installation plate. An adjustment plate is inserted into the inner side of the through hole. A cross bar is fixedly connected to the opposite side of the adjustment plate. A movable frame is movably connected to the surface of the cross bar. A functional rod is fixedly connected to one side of the movable frame. A pull rod is arranged inside the functional rod. One end of the pull rod is fixedly connected with a clamping seat. A rotating column is movably connected to the surface of the clamping seat. One end of the rotating column is fixedly connected with a contact seat.

[0004] The above patent has the following deficiencies: 1. When using the clamping seat to clamp the steel structure, the clamping force provided by the spring is often limited, which may lead to insufficient stability of the steel structure during the clamping process. At the same time, during the coating construction, it is difficult to flexibly move the steel structure, making it difficult to paint the blocked area, thus reducing the convenience of use; 2. Some toxic gases are easily generated during the painting process, and it is easy for operators to absorb the toxic gases and cause harm to the body, which is not conducive to improving the safety during operation.

[0005] Therefore, there is an urgent need for a special jig for steel structure painting to solve the above problems. Content of the Utility Model

[0031] Such as Figures 1-7As shown in the figure, this embodiment proposes a special jig for steel structure painting, which includes a mobile frame 100. A lifting frame 101 is slidably connected to the top wall of the mobile frame 100. A fixing component is rotatably connected to the side wall of the lifting frame 101. The fixing component includes a deflecting frame 102 rotatably connected to the side wall of the lifting frame 101. A limiting groove 103 is formed on the outer wall of the deflecting frame 102. A fixing frame 104 is slidably connected to the outer wall of the deflecting frame 102 through the limiting groove 103. Two groups of fixing frames 104 are symmetrically arranged about the central axis of the deflecting frame 102. An adjusting wheel 105 is rotatably connected to the bottom wall of the fixing frame 104. An air extraction component for absorbing spraying gas is connected to the side wall of the deflecting frame 102. When the adjusting wheel 105 contacts the steel structure, it is convenient to improve the convenience of moving the steel structure.

[0032] As Figures 1-4 shown, as a preferred embodiment, on the basis of the above method, further, a clamping plate 110 is slidably connected to the side wall of the fixing frame 104. Two groups of clamping plates 110 are symmetrically arranged about the central axis of the fixing frame 104. A bidirectional screw 111 is rotatably connected to the inner wall of the fixing frame 104. The bidirectional screw 111 is threadedly connected to the clamping plate 110. A fitting plate 112 is slidably connected to the inner wall of the clamping plate 110. A tension spring 113 is fixedly connected to the inner wall of the clamping plate 110. Two groups of tension springs 113 are symmetrically arranged about the central axis of the clamping plate 110. The tension spring 113 is fixedly connected to the fitting plate 112. By setting the bidirectional screw 111 to drive the clamping plate 110 to move synchronously, it is convenient to improve the stability when clamping the steel structure.

[0033] As Figures 1-6 shown, as a preferred embodiment, on the basis of the above method, further, the air extraction component includes an air extraction pipe 120 fixedly connected to the side wall of the deflecting frame 102. An absorption box 121 is fixedly connected to the side wall of the deflecting frame 102. A delivery pipe 122 is fixedly connected to the outer wall of the absorption box 121. Two groups of delivery pipes 122 are symmetrically arranged about the central axis of the absorption box 121. An air extraction and delivery pump 123 is fixedly connected to the outer wall of the delivery pipe 122. The air extraction pipe 120, the delivery pipe 122 and the absorption box 121 are connected in communication. By setting the air extraction pipe 120, it is convenient to absorb toxic gases, thereby improving the safety of operators during use.

[0034] As Figures 1-2 shown, as a preferred embodiment, on the basis of the above method, further, a driving screw 130 is rotatably connected to the inner wall of the mobile frame 100. Two groups of driving screws 130 are symmetrically arranged about the central axis of the mobile frame 100. The driving screw 130 is threadedly connected to the lifting frame 101. The height of the lifting frame 101 can be adjusted as needed through the driving screw 130, and the practicability is stronger.

[0035] As Figures 1-7As shown, as a preferred embodiment, on the basis of the above method, further, a servo motor 131 is fixedly connected to the side wall of the lifting frame 101, a first gear 132 is fixedly connected to the output end of the servo motor 131, a second gear 133 is fixedly connected to the side wall of the deflection frame 102, and the first gear 132 is meshed with the second gear 133. A fixing bolt 134 is threadedly connected to the inner wall of the fixing frame 104. The deflection angle of the deflection frame 102 can be adjusted by the servo motor 131, which is more convenient to use.

[0036] Specifically, when this special tire rack for steel structure painting is in use: First, loosen the fixing bolt, and then slide the fixing frame 104 to adjust the position of the fixing frame 104 to facilitate adapting to steel materials of different lengths. After the adjustment is completed, fix the fixing frame 104 by tightening the fixing bolt. Then, pull the fitting plate 112 to place the steel structure to be painted on the clamping plate 110. Then, under the action of the tension spring 113, pull the fitting plate 112 to fit with the steel structure. Then, by rotating the bidirectional screw 111, drive the clamping plates 110 on both sides to move synchronously towards the middle at the same time, and fix the steel structure through the clamping plates 110, thereby improving the stability after clamping the steel structure. Then, paint the steel structure. When painting, start the pumping and sending pump 123, and draw the harmful gases generated during painting into the absorption box 121 through the air extraction pipe 120 and the conveying pipe 122, thereby improving the safety of the operator during operation. At the same time, the servo motor 131 can be started according to the painting needs to drive the first gear 132 to rotate, and drive the second gear 133 to rotate through the first gear 132, thereby realizing the adjustment of the angle of the deflection frame 102 and improving the convenience during painting. When the steel structure needs to be moved, drive the clamping plates 110 on both sides to separate by rotating the bidirectional screw 111. Thus, after the steel structure contacts the adjusting wheel 105, the convenience of moving the steel structure is realized by sliding the steel structure, which is more convenient to use. By starting the driving screw 130, the height of the lifting frame 101 can be adjusted to facilitate adapting to different use requirements, and the applicability is stronger.
