Description

Technical Field

[0001] This utility model relates to the field of steel structure painting technology, and in particular to a steel structure painting device. Background Technology

[0002] Steel structures are widely used in industrial plants, commercial buildings, bridges, high-rise buildings, stadiums, and other fields. Due to the high precision of steel structure components, ease of on-site construction, and relatively fast construction speed, construction periods can be shortened, facilitating project progress. Steel can also be recycled and reused, reducing the consumption of natural resources. Furthermore, steel structures reduce environmental pollution from cement and mortar during construction.

[0003] However, steel structures exposed to the atmosphere are susceptible to corrosion from oxygen, moisture, and other corrosive substances, leading to rust and corrosion on the steel surface, which in turn accelerates the aging of the steel.

[0004] Applying paint to the exterior of steel to form a protective film is a way to extend the service life of steel structures. However, the painting process requires manual turning of the steel and air drying after painting. This makes the painting process labor-intensive and significantly reduces painting efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Please see Figures 1 to 6 The steel structure painting device of this utility model includes an outer frame 100, a transmission component 120 is installed in the middle of the lower inner wall of the outer frame 100, and a clamping component 130 for clamping steel structure parts is installed at the outer edge of the transmission component 120.

[0033] The transmission assembly 120 includes a support plate 121 erected inside the outer frame 100. A top plate 122 is welded to the top of the support plate 121. A synchronous belt 123 connected to the clamp 130 is sleeved on the outer wall of the top plate 122. A drive motor 126 for driving the synchronous belt pulley 124 to rotate is installed at the bottom of the top plate 122. The rear edge of the synchronous belt 123 extends vertically downward. Auxiliary pulleys 127 are rotatably provided at the rear surface of the support plate 121 and the inside corner of the synchronous belt 123. Spray paint frames 150 for spraying paint on steel structural components are provided on both sides of the synchronous belt 123.

[0034] The paint frame 150 is composed of multiple sets of U-shaped spray strips. The multiple sets of spray strips are distributed longitudinally at equal intervals and fixed by rigid metal tubes 151. The rigid metal tubes 151 are connected to each set of spray strips. The multiple sets of spray strips and the rigid metal tubes 151 form a channel for the steel structure components to pass through. The bottom of the rigid metal tubes 151 extends to the outside of the outer frame 100.

[0035] On both sides of the synchronous belt 123, opposite the paint spray frame 150, air jet frames 140 are installed. The outer wall of the air jet frame 140 is connected to an air supply pipe 141, and the end of the air supply pipe 141 extends to the outside of the outer frame 100.

[0036] The inner wall of the jet frame 140 is provided with several sets of jet nozzles, which can blow air onto the outer wall around the steel structure.

[0037] The front surface of the outer frame 100 has a notch for taking out and putting in steel structural components, and the control screen 110 is installed on one side of the notch on the front surface of the outer frame 100.

[0038] The bottom of the support plate 121 is equipped with an electric push rod that can push the support plate 121 and the top plate 122 to rise. There is a space between the top of the top plate 122 and the top of the inner frame 100 that can be raised.

[0039] It is worth noting that the air entering the jet frame 140 can be hot air, and the temperature of the hot air is moderate, which can accelerate the drying of the paint on the steel structure. As an example, the air supply pipe 141 can be connected to an electrically heated hot air unit. The aforementioned electrically heated hot air unit heats the air through an electric heating element, and sends the hot air into the aforementioned air supply pipe 141 through a fan.

[0040] The steel structural component to be painted is fixed in the clamp 130. At this time, the drive motor 126 outputs power to drive the synchronous belt pulley 124 to rotate. The two sets of drive motors 126 rotate in the same direction, and with the cooperation of the auxiliary pulley 127, they drive the synchronous belt 123 to transmit along the preset trajectory. During this process, the steel structural component will be driven into the channel formed by the spray frame 150 through the clamp 130. The steel structural component passes through the channel from top to bottom. At this time, external equipment delivers paint to the rigid metal tube 151, as shown in the instruction manual. Figure 2 As shown, the rigid metal tube 151 also supports the paint spray frame 150, and its air supply pipe 141 also supports the air spray frame 140. The paint in the rigid metal tube 151 is diverted to each set of spray bars to paint the steel structure from multiple directions, thereby accelerating the painting efficiency.

[0041] As the synchronous belt 123 moves, the painted steel structure will enter the air jet frame 140. External equipment will deliver hot air to the air jet frame 140 through the air supply pipe 141, and the hot air will also be blown towards the steel structure from multiple directions to improve the drying efficiency of the paint on the outer wall.

[0042] When the length of the steel structural components is different, the electric push rod can be controlled to push the support plate 121 and the top plate 122 to rise, thereby adjusting the distance between the bottom of the steel structural component and the highest point of the paint spraying frame 150, so as to ensure that the steel structural component can enter the channel and be painted by the paint spraying frame 150.

[0043] It should be noted that there is a certain distance between the two sets of clamping parts 130 to avoid the two sets of steel structural parts from colliding when the synchronous belt 123 is in the vertical area. The distance between the two sets of clamping parts 130 can be adjusted according to the size of the steel structural parts. The clamping parts 130 and the synchronous belt pulley 124 described above can be fixed by bolts or rivets.

[0044] Please see Figure 2 and Figure 5 The clamp 130 includes a frame 131 fixedly connected to the outer wall of the timing belt 123. Clamping plates 132 are slidably provided on both sides inside the frame 131. Each set of clamping plates 132 has a handle 133 rotatably provided on the outer wall of the frame 131 extending to the outside of the frame 131. The frame 131 and the handle 133 are provided with matching threaded holes at the contact positions.

[0045] The top of the steel structural component to be painted is inserted into the sleeve 131. At this time, the handle 133 is turned to apply a lateral external force to the clamping plate 132, driving the two sets of clamping plates 132 to move closer to the center and fit against the outer wall of the steel structural component, so that the steel structural component is fixed in the sleeve 131 and waits for painting. The end of the steel held by the sleeve 131 can wait for the upper and lower ends of the steel structural component to be swapped before painting.

[0046] Please see Figure 2 and Figure 3 A transmission groove 125 is provided at the position where the top plate 122 contacts the synchronous belt 123. The synchronous belt pulley 124 is rotatably connected in the transmission groove 125 and is used to drive the synchronous belt 123.

[0047] The transmission groove 125 provides a stable rotation space for the synchronous belt pulley 124 and enables the synchronous belt 123 to drive the steel structure components to undergo painting and heating drying processes in sequence.

[0048] Please see Figure 6The rear surface of the outer frame 100 has a maintenance window, and a pair of movable doors 101 are installed inside the maintenance window. By opening the movable doors 101, the air jet frame 140 and the paint spray frame 150 can be maintained, and the dried paint inside the bottom of the outer frame 100 can be cleaned.

[0049] Please see Figure 4 The jet frame 140 and the paint spray frame 150 are in a non-contact state with the outer wall of the synchronous belt 123, ensuring smooth transmission of the synchronous belt 123, thereby driving the steel structure to move for painting and heating and drying.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
