[0002] Steel pipe scaffolds used in construction are widely applied in the construction industry. Steel pipes exposed outdoors for a long time are prone to corrosion, which affects their safety and service life. Therefore, it is necessary to paint the surface of the steel pipes.

[0003] However, manual operation easily leads to inconsistent coating thickness, affecting the anti-corrosion effect. Moreover, manual painting is slow, time-consuming, and has a high labor cost. Summary of the Invention

[0004] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a steel pipe scaffold painting machine at the construction site.

[0005] A steel pipe scaffold painting machine at the construction site provided by the present invention adopts the following technical solutions: A steel pipe scaffold painting machine at the construction site includes a housing. A partition is vertically arranged inside the housing. Pipe holes are opened at corresponding positions of the housing and the partition. A paint bucket with an upward opening is fixedly arranged through the partition. The paint bucket is arranged parallel to the steel pipe. Slide holes are opened on the housing and the partition. The slide holes extend from one side of the paint bucket to one side of the pipe hole. A pull rod is slidably arranged in the slide hole. A painting roller for painting the steel pipe is rotatably sleeved on the pull rod. The painting machine further includes a driving mechanism for driving the steel pipe to rotate.

[0006] By adopting the above technical solutions, the steel pipe is inserted into the pipe hole, and then the steel pipe is driven to rotate by the driving mechanism. During the rotation of the steel pipe, the painting roller is in rolling contact with the steel pipe, so as to evenly paint the paint on the surface of the steel pipe. Pull the pull rod along the slide hole to drive the painting roller to move into the paint bucket to dip the paint, and then pull the pull rod in the reverse direction to make the painting roller return to the working position. The steel pipe scaffold painting machine at the construction site can evenly paint the members, improve the anti-corrosion performance, and accelerate the painting speed through mechanized operation, reduce the labor cost, and improve the painting efficiency.

[0007] Optionally, the driving mechanism includes two roller shafts rotatably connected to the partition. The roller shafts are arranged below the steel pipe and parallel to the steel pipe. A driven gear and a driving wheel are installed on the roller shafts. A transmission shaft is rotatably connected between the partition and the housing. A driving member for driving the transmission shaft to rotate is installed at the end of the transmission shaft. A driving gear is installed on the transmission shaft. The driving gear meshes with the driven gear.

[0008] By adopting the above technical solution, the driving member transmits power to the driving wheel through the transmission shaft, the driving gear, the driven gear, and the roller shaft in sequence. The rotation of the driving wheel drives the rotation of the steel pipe. This driving mechanism is simple and efficient in operation and can effectively meet the construction requirements.

[0009] Optionally, the driving member is in the structural form of a hand crank or a motor combined with a speed reducer.

[0010] By adopting the above technical solution, a manual or electric driving structural form can be adopted and selected according to the actual situation.

[0011] Optionally, the paint hopper extends outside the housing, and a baffle plate is fixedly connected to the end of the paint hopper. Feed openings for the flow of paint are provided on the partition plate and the housing.

[0012] By adopting the above technical solution, paint can be added through the paint hopper, and the paint flows along the paint hopper into the interior of the painting machine.

[0013] Optionally, a recovery hopper is arranged at the bottom inside the housing.

[0014] By adopting the above technical solution, setting the recovery hopper can avoid paint waste, reduce material costs, prevent direct paint discharge, reduce environmental pollution, and conform to the concept of green construction. Description of the Drawings

[0021] An embodiment of the present invention discloses a coating machine for steel pipe scaffolds at a construction site. Refer to Figures 1-3 As shown in Figures 1-3 , the coating machine for steel pipe scaffolds at the construction site includes a rectangular outer shell 1. Inside the outer shell 1, a plurality of vertically arranged partitions 2 are uniformly fixed along the length direction of the outer shell 1. Through holes 3 for the steel pipes to pass through are opened on the front and rear plates of the outer shell 1 and on the partitions 2. The steel pipes pass through from one end of the coating machine to the other end for coating operations.

[0022] Refer to Figures 1-3 As shown in Figures 1-3 , two paint buckets 4 are fixedly arranged between the plurality of partitions 2. The two paint buckets 4 are at the same horizontal height. The cross-section of the paint bucket 4 is semi-circular and the opening is upward. The length direction of the paint bucket 4 is the same as the length direction of the outer shell 1. One end of the paint bucket 4 is fixed to the inner wall of the front plate of the outer shell 1, and the other end of the paint bucket 4 passes through the rear plate of the outer shell 1 and a baffle plate 5 is fixedly connected to the end. Feeding ports 6 are opened on the partitions 2 and the rear plate of the outer shell 1 at positions corresponding to the inner grooves of the paint buckets 4. Construction workers can add paint through the ends of the paint buckets 4, and the paint flows into the interior of the coating machine along the paint buckets 4.

[0023] Refer to Figures 1-4 As shown in Figures 1-4 , arc-shaped sliding holes 7 are opened on the front and rear plates of the outer shell 1 and on the partitions 2. The middle of the sliding hole 7 protrudes upward. One end of the sliding hole 7 is communicated with the feeding port 6, and the other end of the sliding hole 7 extends towards the direction close to the through hole 3. The same pull rod 8 is arranged in a plurality of sliding holes 7 in the same column. A plurality of coating rollers 9 are rotatably sleeved on the pull rod 8. The coating rollers 9 are distributed between adjacent two partitions 2, between the partition 2 and the front plate of the outer shell 1, and between the partition 2 and the rear plate of the outer shell 1. By pulling the pull rod 8 along the sliding hole 7, the coating rollers 9 can be driven to enter the paint bucket 4 to dip the paint and return to the working position close to the steel pipe.

[0024] Refer to Figure 3 and Figure 4 As shown in Figure 3 and Figure 4 , a recovery hopper 10 is arranged at the bottom inside the outer shell 1. The paint dropped during the process of the coating rollers 9 coating the steel pipes can fall into the recovery hopper 10 for recovery. The coating machine further includes a driving mechanism 11 for driving the steel pipe to rotate. The driving mechanism 11 includes a roller shaft 110 rotatably arranged between a plurality of partitions 2. The roller shaft 110 is perpendicular to the partitions 2. Bearings are installed between the roller shaft 110 and the partitions 2. A driven gear 111 is sleeved and fixed on the roller shaft 110.

[0025] Refer to Figure 3 and Figure 4, driving wheels 112 are respectively sleeved and fixed at both ends of the roller shaft 110. The outer diameter of the driving wheel 112 is larger than that of the driven gear 111. The steel pipe is inserted into the pipe passing hole 3 and placed on the four driving wheels 112. A transmission shaft 113 is vertically and rotatably connected to the partition plate 2 near the front plate of the outer shell 1. The transmission shaft 113 rotatably penetrates through the front plate of the outer shell 1. A hand rocker 114 is installed at the end of the transmission shaft 113. A driving gear 115 is also sleeved and fixed on the transmission shaft 113. The driving gear 115 meshes with the driven gear 111. In other embodiments, a structure form of a motor cooperating with a speed reducer can also be adopted as a driving member to drive the transmission shaft 113 to rotate.

[0026] The implementation principle of the steel pipe scaffolding painting machine at the construction site in the embodiment of the present invention is as follows: Insert the steel pipe into the pipe passing hole 3, and then shake the hand rocker 114. The hand rocker 114 transmits the power to the driving wheel 112 through the transmission shaft 113, the driving gear 115, the driven gear 111, and the roller shaft 110 in sequence. The rotation of the driving wheel 112 drives the rotation of the steel pipe. During the rotation of the steel pipe, the painting roller 9 is in rolling contact with the steel pipe, so as to evenly paint the paint on the surface of the steel pipe. The paint that drops during this period falls into the recovery hopper 10 for recovery.

[0027] After a period of time, paint can be added to the inside of the paint bucket 4 through the end of the paint bucket 4. The paint flows along the paint bucket 4. Pull the pull rod 8 along the sliding hole 7, and the painting roller 9 can be driven to move into the paint bucket 4 to dip the paint, and then pull the pull rod 8 in the reverse direction to make the painting roller 9 return to the working position.

[0028] The steel pipe scaffolding painting machine at the construction site can evenly paint the members, improve the anti-corrosion performance, and accelerate the painting speed through mechanized operation, reduce the labor cost, and improve the painting efficiency; the recovery hopper 10 is provided to avoid paint waste, reduce the material cost, avoid direct discharge of paint, reduce environmental pollution, and conform to the concept of green construction.
