Description

Technical Field

[0001] This application relates to the field of paint spraying technology, and more particularly to a steel structure spraying system. Background Technology

[0002] To ensure the corrosion resistance and fire resistance of steel structures during use, a comprehensive painting operation is often required before the steel structure is put into use. Traditional steel structure painting is mainly done manually. This method is not only inefficient, but also limits the worker's control over the amount of paint sprayed, which can easily lead to paint waste and uneven paint film thickness. In addition, there is another important problem: the paint can be very harmful to the health of the operators. Because the traditional method involves workers holding spray guns and spraying the steel components directly, even if workers wear protective equipment such as masks and protective clothing, it is still difficult for them to avoid being contaminated by the paint due to the close proximity between them and the paint. Consequently, the workers' health is easily affected by the paint. Utility Model Content

[0003] This application provides a steel structure spraying system that can replace manual labor for spraying large quantities of steel components. It can not only effectively improve spraying efficiency and quality, but also reduce the health hazards to workers during the paint spraying process.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A steel structure spraying system includes a first electric traveling gantry crane. The first electric traveling gantry crane includes a first horizontal main beam. A first trolley that can move freely along its length is installed on the first horizontal main beam. A first leg is fixedly connected to the lower side of each end of the first horizontal main beam. A first ground beam is welded below each of the first legs. A first motor drive wheel is provided on the first ground beam.

[0006] A first steel guide rail is laid on each side of the steel structure to be sprayed, and the first motor drive wheels on the two first ground beams are respectively placed above the two first steel guide rails.

[0007] A paint spraying device is installed below the first trolley on the first horizontal main beam, and a paint storage tank is installed on the top of the first trolley. The paint storage tank is used to provide paint for the paint spraying device.

[0008] A second electric traveling gantry crane is provided on one side of the first electric traveling gantry crane. The second electric traveling gantry crane is equipped with a turning device, which is used to turn over the steel structure after it has been painted by the paint spraying equipment.

[0009] Furthermore, a shielding curtain is suspended circumferentially below the horizontal main beam, and the lower end of the shielding curtain is not lower than the height of the top surface of the steel structure to be sprayed.

[0010] Furthermore, a support pad is laid between the two first steel guide rails, and the width of the support pad is smaller than the distance between the two first steel guide rails.

[0011] Furthermore, multiple cement blocks of the same size are cast above the support pad, and the multiple cement blocks are arranged in a matrix above the support pad.

[0012] Furthermore, the second electric traveling gantry crane includes a second horizontal main beam, with a second leg fixedly connected to each end of the second horizontal main beam. A second ground beam is welded below each of the two second legs, and a second motor drive wheel is installed on the lower side of each of the two second ground beams. A second trolley that can move freely along its length is installed on the second horizontal main beam, and an electric hoist is installed below the second trolley. The hook of the electric hoist is connected to the tilting device.

[0013] Furthermore, a second steel guide rail is provided on each of the two first steel guide rails on their opposite sides, and the second motor drive wheels on the two second ground beams are respectively placed on the two second steel guide rails; the height of the second horizontal main beam of the second electric traveling gantry crane is higher than the height of the first horizontal main beam of the first electric traveling gantry crane, and the lifting range of the electric hoist in the second electric traveling gantry crane is sufficient to lift the tilting device above the highest point of the first horizontal main beam.

[0014] Furthermore, the flipping device is a bag-type flipping machine.

[0015] Furthermore, the paint spraying equipment is a programming-free six-axis spraying robot.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This application installs a paint spraying device on a first trolley in a first electric traveling gantry crane. The first trolley can move freely along the first horizontal main beam of the first electric traveling gantry crane, and the first motor drive wheel can move freely along the first steel guide rail. Correspondingly, the paint spraying device on the first trolley can move freely not only along the length of the first horizontal main beam, but also along the length of the first steel guide rail. In this way, the paint spraying device can basically cover all areas between the two first steel guide rails. By evenly placing the steel structure to be sprayed between the two first steel guide rails, the paint spraying device can achieve the effect of comprehensive spraying of the steel structure. Both the first trolley and the first motor drive wheel are controlled by electronic equipment. Compared with the method of manually operating the paint spray gun by workers, the spraying effect will be more uniform and the spraying efficiency will be higher. Moreover, during the spraying process, workers can maintain a sufficient safe distance from the paint to prevent paint contamination and affect their health. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0024] like Figure 1 and Figure 2 As shown, this application discloses a steel structure spraying system, which includes a first electric traveling gantry crane 1. The first electric traveling gantry crane 1 includes a first horizontal main beam 101. A first trolley 102 that can move freely along its length is installed on the first horizontal main beam 101. A first support leg 103 is fixedly connected to the lower side of each end of the first horizontal main beam 101. A first ground beam 104 is welded below each of the first support legs 103. A first motor drive wheel 105 is provided on the first ground beam 104.

[0025] A first steel guide rail 2 is laid on each side of the steel structure to be sprayed, and the first motor drive wheel 105 on the two first ground beams 104 is placed above the two first steel guide rails 2 respectively.

[0026] A paint spraying device 3 is installed below the first trolley 102 on the first horizontal main beam 101. A paint storage tank 4 is installed on the top of the first trolley 102. The paint storage tank 4 is used to provide paint for the paint spraying device 3.

[0027] A second electric traveling gantry crane 5 is provided on one side of the first electric traveling gantry crane 1. The second electric traveling gantry crane 5 is equipped with a flipping device 6, which is used to flip the steel structure after it has been painted by the paint spraying equipment 3.

[0028] In the above embodiments, the biggest difference between the electric traveling gantry crane and the traditional fixed gantry crane is that a moving wheel with a drive motor (i.e., the first motor drive wheel 105 of this application) is installed on the ground beam. After the moving wheel with the drive motor is started, the entire gantry crane can automatically move forward and backward along the track. Other parts are basically the same as the traditional gantry crane. A trolley that can move freely is provided on the main beam (the trolley has a motor inside, and the motor housing drives the trolley to move freely along the length of the main beam). Lifting equipment such as an electric hoist 56 for lifting objects is installed under the trolley.

[0029] The first electric traveling gantry crane 1 of this application is based on an electric traveling gantry crane, in which the electric hoist 56 is replaced with a paint spraying device 3. Because the main body of the gantry crane can move along the first steel guide rail 2, for ease of understanding, this direction is defined as the first direction. The first trolley 102 can move along the length of the first horizontal main beam 101, for ease of understanding, this direction is defined as the second direction. The first direction and the second direction are perpendicular to each other in space. Moreover, when the first electric traveling gantry crane 1 moves along the first direction, the first trolley 102 and the paint spraying device 3 also move together with it. In addition, the paint spraying device 3 can also move along the second direction through the first trolley 102. In this way, the range of motion of the paint spraying device 3 can basically cover the entire area between the two first steel guide rails 2. In actual production, as long as the workers lay the steel structure to be painted between the two first steel guide rails 2 in advance, the first electric traveling gantry crane 1 of this application can use the paint spraying device 3 to uniformly paint the upper part of these steel structures.

[0030] During the placement of the steel structure to be painted, a portion of it will inevitably be in contact with the ground. The paint spraying equipment 3 located above cannot directly spray this part of the steel structure. Therefore, this application adds a second electric traveling gantry crane 5 on the other side of the first electric traveling gantry crane 1. The second electric traveling gantry crane 5 is equipped with a tilting device 6. After the first electric traveling gantry crane 1 has sprayed the first coat of paint on the steel structure on the ground and the paint has initially hardened, the second electric traveling gantry crane 5 can cooperate with the workers to tilt these steel structures so that one side of them faces upward. Subsequently, the second electric traveling gantry crane 5 is moved once more above these tilted steel structures to spray the second coat of paint, thus completing the effect of spraying paint on the entire outer surface of these steel structures.

[0031] Compared to the existing manual painting method, this application adopts a machine painting method using an electric traveling gantry crane in conjunction with a paint spraying device 3, combined with another electric traveling gantry crane in conjunction with a turning device 6 to turn the steel structure over in a timely manner to ensure the comprehensiveness of the paint spraying. Both the spraying efficiency and the uniformity of the spraying can be effectively improved. Moreover, during the spraying process, workers can maintain a sufficient safe distance from the paint spraying area, thus reducing the harm to workers' health during the paint spraying process.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, a shielding curtain 7 is suspended along the circumference below the horizontal main beam, and the lower end of the shielding curtain 7 is not lower than the height of the top surface of the steel structure to be sprayed.

[0033] In the above embodiments, the shielding curtain 7 can reduce the risk of paint spreading outwards during the process of the paint spraying equipment 3 spraying paint onto the steel structure, and can also prevent airflow outside the production area from interfering with the paint spraying effect. Because the first electric traveling gantry crane 1 of this application needs to move along the first steel guide rail 2, in order to prevent the shielding curtain 7 from rubbing against the steel structure to be sprayed, the height of the lower end of the shielding curtain 7 is set not lower than the height of the highest point of the steel structure to be sprayed.

[0034] Furthermore, such as Figure 1 As shown, a support pad 8 is laid between the two first steel guide rails 2, and the width of the support pad 8 is smaller than the distance between the two first steel guide rails 2.

[0035] In the above embodiments, the specially laid support blocks 8 ensure that the steel structures to be painted are placed on the same horizontal plane. This ensures that the distance between the paint spraying equipment 3 and each steel structure is not too different, thereby reducing the difference in painting quality on different steel structures. The width of the support blocks 8 in this application is smaller than the distance between the two first steel guide rails 2. This ensures that there is a gap between the two ends of the support blocks 8 in the width direction and between the two first steel guide rails 2, thus providing a certain amount of operating space when placing the steel structure on the support blocks 8.

[0036] Furthermore, such as Figure 1 As shown, multiple cement blocks 9 of the same size are poured on top of the support pad 8, and the multiple cement blocks 9 are arranged in a matrix above the support pad 8.

[0037] In the above embodiments, the length of the steel structure to be sprayed in actual production is not uniform. In this application, multiple cement blocks 9 of the same specification are evenly set on the support pad 8. In this way, even if some steel structures with shorter lengths need to be placed, their ends can be suspended in the air, making it easy to lift or put down. At the same time, when there is water accumulation in the production area, the gaps between the cement blocks 9 can also guide the water flow to prevent water from accumulating in the spraying area. Moreover, the cement blocks 9 further raise the height of the steel structure from the ground based on the support pad 8, which can reduce the impact of ground moisture on the steel structure.

[0038] Furthermore, such as Figure 1 and Figure 3 As shown, the second electric traveling gantry crane 5 includes a second horizontal main beam 51. A second leg 52 is fixedly connected to each end of the second horizontal main beam 51. A second ground beam 53 is welded below each of the two second legs 52. A second motor drive wheel 54 is installed on the lower side of each of the two second ground beams 53. A second trolley 55 that can move freely along its length is installed on the second horizontal main beam 51. An electric hoist 56 is installed below the second trolley 55. The hook of the electric hoist 56 is connected to the tilting device 6.

[0039] In the above embodiments, the structure of the second electric traveling gantry crane 5 of this application is the same as that of the existing electric traveling gantry crane. Its second horizontal main beam 51 is the main beam in the existing electric traveling gantry crane. The second trolley 55 set on the second horizontal main beam 51 has a built-in drive motor, which can drive it to move along the length direction of the second horizontal main beam 51. The second motor drive wheel 54 installed on the second ground beam 53 below the second support leg 52 can drive the entire second electric traveling gantry crane 5 to move along the same trajectory as the first electric traveling gantry crane 1. The main difference between the second electric traveling gantry crane 5 and the first electric traveling gantry crane 1 in this application is that it retains the electric hoist 56 on the second trolley 55. This is because when flipping the steel structure, the height of the flipping device 6 in the vertical direction can be adjusted by the electric hoist 56. In addition, the first trolley 102 of the second electric traveling gantry crane 5 has a paint storage bucket 4, which workers often need to go up to inspect and replenish or check the paint in the paint storage bucket 4. Therefore, the overall width of the second electric traveling gantry crane 5 in this application needs to be set to be greater than that of the first electric traveling gantry crane 1, and a guardrail is added to the first horizontal main beam 101, and a ladder is set on one side of the first horizontal main beam 101.

[0040] Furthermore, such as Figure 1 and Figure 2 As shown, a second steel guide rail 10 is provided on the opposite side of the two first steel guide rails 2, and the second motor drive wheels 54 on the two second ground beams 53 are respectively placed on the two second steel guide rails 10; the height of the second horizontal main beam 51 of the second electric traveling gantry crane 5 is higher than the height of the first horizontal main beam 101 of the first electric traveling gantry crane 1, and the lifting range of the electric hoist 56 in the second electric traveling gantry crane 5 is sufficient to lift the tilting device 6 above the highest point of the first horizontal main beam 101.

[0041] In the above embodiments, the second motor drive wheel 54 and the first motor drive wheel 105 of this application are placed on guide rails at different positions, and the second horizontal main beam 51 is higher than the first horizontal main beam 101. In this way, the risk of interference between the first electric traveling gantry crane 1 and the second electric traveling gantry crane 5 can be reduced during use. Taking a steel structure of about 8 meters as an example, it takes about 20 minutes for the first electric traveling gantry crane 1 of this application to spray one coat of paint. If a fast-drying paint is used, the paint will dry completely in about 3 hours. The turning device 6 can only perform the turning operation on the dried steel structure, which can prevent the paint from peeling off the steel structure. If this application places 20 steel structures, each approximately 8 meters long, along the length of the two first steel guide rails 2, then when the first electric traveling gantry crane 1 is painting the 10th steel structure, the second electric traveling gantry crane 5 can flip the steel structure that was first painted with the first coat of paint. After the first electric traveling gantry crane 1 has finished painting the first coat of paint on all the steel structures, there will still be a certain distance between the second electric traveling gantry crane 5 and the last steel structure painted by the first electric traveling gantry crane 1. At this point, the first electric traveling gantry crane 1 cannot continue to paint the steel structure with the second coat of paint by returning along the first steel guide rail 2. The first electric traveling gantry crane 1 needs to return to the starting point along the first steel guide rail 2 because the steel guide rail at its starting point has already been flipped by the first electric traveling gantry crane 1 and can be painted with the second coat of paint. The first steel guide rail 2 used for the movement of the first electric traveling gantry crane 1 is located inside the second steel guide rail 10 used for the movement of the second electric traveling gantry crane 5. When the hook of the electric hoist 56 in the second electric traveling gantry crane 5 is raised to the highest point, the height of the tilting device 6 hanging on its hook is higher than the first horizontal main beam 101. The main purpose of this arrangement is to ensure that the first electric traveling gantry crane 1 will not be blocked by the second electric traveling gantry crane 5 which is moving during the process of returning to its initial position.

[0042] Furthermore, such as Figure 1 and Figure 3 As shown, the flipping device 6 is a bag-type flipping machine.

[0043] In the above embodiments, the turning machine is a material turning device frequently used in many industrial fields such as automobile manufacturing, electronic assembly, pharmaceutical packaging, food processing, and metal processing. Common turning machines are divided into chain turning machines and bag turning machines (for example, Keda Industrial Equipment (Shandong) Co., Ltd. and Wuxi Shiyang Heavy Industry Machinery Co., Ltd. sell these two types of turning machine equipment). The reason why this application chose the bag turning machine is to reduce the wear on the paint surface of the steel structure during the turning process.

[0044] Furthermore, such as Figure 2 As shown, paint spraying equipment 3 is a programming-free six-axis spraying robot.

[0045] In the above embodiments, the robotic arm of the programming-free six-axis painting robot can simulate the joint structure of a human arm, with six rotation axes, allowing for flexible turning in three-dimensional space to handle steel structures of various shapes and sizes. This paint spraying equipment 3 is equipped with an intuitive operating interface and intelligent guidance system, making it easy for even non-professional programmers to use. This equipment has been widely used in furniture manufacturing, automotive painting, and other fields. By using the programming-free six-axis painting robot, high-quality steel structure painting operations can be completed more accurately, saving manufacturing companies significant manpower and time costs, and effectively reducing paint waste.

[0046] The implementation principle of this embodiment is as follows: Before the spraying operation begins, workers use forklifts or cranes to place the steel structures one by one along the length of the first steel guide rail 2. Then, workers can climb onto the first horizontal main beam 101 of the first electric traveling gantry crane 1 and add the prepared paint to the paint storage tank 4. Next, the drive motors in the paint spraying equipment 3, the first trolley 102, and the first motor drive wheel 105 can be started. The paint spraying equipment 3 will first move along the first horizontal main beam 101, and then adjust its position along the direction of the first steel guide rail 2 until the entire steel structure between the two first steel guide rails 2 is sprayed. During the operation of the first electric traveling gantry crane 1, after the paint on the surface of the steel structure has dried and cured, the second motor drive wheel 54 on the second electric traveling gantry crane 5 can move along the second steel guide rail 10 to the front of the steel structure. The flipping device 6 is used to flip the dried steel structure, adjusting the parts that have not been sprayed to the top. After the first electric traveling gantry crane 1 completes the first coat of paint on all the steel structures, the second coat of paint can be applied to the steel structure that has been flipped over by the second motor drive wheel 54 to ensure that the appearance of all steel structures is fully covered with paint. Compared with the existing manual painting method, this application adopts a machine painting method using an electric traveling gantry crane in conjunction with the paint spraying equipment 3. Both the spraying efficiency and the uniformity of the spraying can be effectively improved. Moreover, during the spraying process, workers can maintain a sufficient safe distance from the paint spraying area, which can reduce the harm to workers' health during the paint spraying process.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 application.
