Description

Technical Field

[0001] This invention relates to the field of H-beam spraying technology, specifically to a spray nozzle guide device for spraying steel structure surfaces. Background Technology

[0002] During the production of steel structures, the finished products need to be coated to improve their corrosion resistance and extend their service life. Steel structures come in various shapes, including I-beams and flat steel.

[0003] Currently, there are many devices used for steel structure spraying, including a steel structure spraying device disclosed in Chinese Patent Publication No. CN208407435U. This device includes a paint tank, a spray pump, a hose, a spray booth, a conveying device, a left slide bar, a right slide bar, a left slider, a right slider, a left threaded transmission rod, a right threaded transmission rod, a left ball bearing, and a right ball bearing. A left motor and a right motor are respectively installed at the left and right ends of the bottom wall of the working chamber. Spray nozzles are installed at the right end of the left slider and the left end of the right slider. The device also includes an exhaust fan and a treatment box. The treatment box has two sets of filters and multiple sets of ultraviolet lamps arranged horizontally inside. Both sets of filters are coated with a photocatalyst layer. An exhaust pipe is installed at the top of the treatment box, and a gas collection hood is installed on the inner top wall of the working chamber. The upper motor, vertical motor, and lower motor are connected to the control mechanism. A Chinese patent with publication number CN218394228U discloses a steel structure spraying machine for uniform spraying, which includes a support platform. The top of the support platform is equipped with a spraying component. The spraying component includes a mounting plate, a support column, a first connecting seat, a mounting pipe, a spray pipe, and a mixing component. The mounting plate is fixedly installed on one side of the top of the support platform. The support column is fixedly connected to one side of the top of the mounting plate. The top of the support column is fixedly connected to the first connecting seat. The mounting pipe is rotatably connected to the inside of the first connecting seat through a short shaft.

[0004] The spraying device provided by the first disclosed patent has poor mobility. When spraying H-beams, it requires lifting equipment to support the H-beams and control their entry and exit from the spraying device. This method is cumbersome and time-consuming due to the large mass of the H-beams, hindering efficient spraying. Furthermore, the limited internal space of the spraying device makes it difficult to rotate; therefore, after spraying one side of the H-beam, it must be rotated to spray the other sides, further reducing efficiency. The spraying machine provided by the second disclosed patent, while more flexible and able to move along the length of the H-beam, requires operators to repeatedly adjust the nozzle orientation to achieve comprehensive spraying, increasing labor intensity and reducing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a spray nozzle guide device for spraying steel structure surfaces, which aims to improve the problem of spraying I-beams that are difficult to move, requiring the use of lifting equipment to support the I-beams or the need to adjust the spray gun orientation multiple times.

[0036] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1

[0038] like Figures 1-16 As shown, a spray nozzle guide device for spraying steel structure surfaces includes a spray guide assembly 2. The spray guide assembly 2 includes a spraying mechanism 6, a support mechanism 5, a lifting plate assembly 4, and multiple guide plates 7. The lifting plate assembly 4 includes an adjustable upper plate 41 and a lower plate 44. The lower plate 44 is set on a base plate 1 to provide support for the operation of the spray guide assembly 2. The multiple guide plates 7 are connected end to end to form a ring structure. The support mechanism 5 is set at the upper end of the upper plate 41. The ring formed by the guide plates 7 can pass through the support mechanism 5 and can be controlled to rotate around the axis under the action of the support mechanism 5. The spraying mechanism 6 includes a spray nozzle 61, which is set inside the ring and perpendicular to the ring. A caster wheel is installed below the base plate 1. A sprayer 11, a storage cylinder 13, and a push handle 12 are mounted on the base plate 1. The storage cylinder 13 stores paint, and its feed port is connected to the feed end of the sprayer 11. The feed end of the sprayer 11 is connected to the nozzle 61 via a pipe. Therefore, before spraying the H-beam, the guide plates 7 are disassembled and assembled as needed, so that the guide plates 7 are fitted onto the outside of the H-beam. When the sprayer 11 is working, it can deliver paint to the nozzle 61 and spray it onto the H-beam, achieving the spraying treatment of the H-beam. During the spraying process, the support mechanism 5 controls the guide plates 7 to rotate back and forth, achieving spraying of multiple sides at the same location. During the spraying of the H-beam, the operator can move the base plate 1 according to the spraying progress to ensure comprehensive spraying of the H-beam. This setup changes the previous situation where lifting equipment was needed to move the I-beams or the direction of the spray nozzles 61 needed to be adjusted multiple times, thus improving the spraying efficiency of the I-beams and reducing the labor intensity of the workers.

[0039] like Figures 1-16 As shown, in order to facilitate the fitting of the ring composed of guide plates 7 onto the I-beam, in this scheme, six guide plates 7 are provided, and each guide plate 7 has a connecting groove 72 at the end of its outer side. A connecting plate 73 can be detachably installed in the space formed by adjacent connecting grooves 72. For example, the connecting plate 73 and the guide plate 7 can be connected by connecting bolts. This arrangement allows the staff to easily disassemble two guide plates 7 according to actual needs, thus forming a notch on the ring. The width of the notch is greater than the width of the I-beam. Therefore, the ring can be fitted onto the I-beam from the side.

[0040] like Figures 1-16As shown, in order to connect the nozzle 61 to the guide plate 7, an installation groove 74 is provided on the inner side of a certain guide plate 7. At the same time, a sleeve 63, a connecting rod 65, and an end plate 66 are vertically arranged on the side of the nozzle 61. The sleeve 63 is sleeved on the connecting rod 65, and the end of the fastening bolt with thread through the sleeve 63 presses against the side wall of the connecting rod 65. In order to ensure that the connecting rod 65 and the sleeve 63 are relatively stationary, the inner end face of the sleeve 63 and the end face of the connecting rod 65 are both set as concave and convex structures. In this case, it can be ensured that the nozzle 61 is stable and perpendicular to the guide plate 7. The end plate 66 is located at the end of the connecting rod 65, and the end plate 66 is detachably installed in the installation groove 74. For example, the end plate 66 is connected in the installation groove 74 by a connecting bolt. Two symmetrical arc-shaped clamps 64 are provided at the end of the sleeve 63. Each arc-shaped clamp 64 has a limiting rod on its inner side. The nozzle 61 has a limiting groove 62 that runs through the space formed by the two arc-shaped clamps 64. The limiting rod is located in the limiting groove 62. With the cooperation of the limiting groove 62 and the limiting rod, the nozzle 61 is stably placed relative to the sleeve 63.

[0041] like Figures 1-16 As shown, to ensure the stability and rotatability of the ring formed by the guide plates 7 on the side of the support mechanism 5, the support mechanism 5 includes a support frame 8, two sets of inclined bracing plates 51, a bidirectional screw 53, two drive shafts 52, and two arc-shaped plates 55. The two sets of inclined bracing plates 51 are symmetrically arranged on the side of the support frame 8 and are hinged to the support frame 8. The two drive shafts 52 are connected to the two sets of inclined bracing plates 51 one by one, and are threaded onto both ends of the bidirectional screw 53. The bidirectional screw 53 is also connected to the support frame 8. Therefore, when the adjustment is rotated... When the screw 43 is adjusted, the included angle of the two sets of inclined support plates 51 can be adjusted. Two arc-shaped plates 55 are respectively hinged to the ends of the two sets of inclined support plates 51, and the cross-section is set as a U-shaped structure. A roller 56 is set on the arc-shaped plate 55. A drive gear 54 is installed through one of the arc-shaped plates 55. The drive gear 54 is connected to the drive motor. The guide plate 7 is set through the arc-shaped plate 55. The roller 56 is in rolling contact with the inner side of the guide plate 7. The outer side of the guide plate 7 is provided with tooth grooves 71. The drive gear 54 meshes with the tooth grooves 71. Under the action of the roller 56, the ring formed by the guide plates 7 is stably and movably installed through the arc-shaped plate 55, without affecting the rotation of the ring formed by the guide plates 7. When the H-beams forming a ring through the guide plates 7 are being sprayed, the drive motor rotates regularly in both directions, thereby controlling the drive gear 54 to rotate. Since the drive gear 54 is meshed with the guide plates 7, it controls the guide plates 7 to drive the spray nozzle 61 to make regular circular motions, achieving complete spraying of the side of the H-beams. When spraying H-beams of different sizes, guide plates 7 of different sizes can be replaced. In order to stably support guide plates 7 of different sizes, the operator can rotate the bidirectional screw 53 to adjust the tilt angle of the inclined support plate 51, thereby adjusting the position of the arc plate 55 to stably clamp the ring formed by the guide plates 7.

[0042] like Figures 1-16 As shown, to accommodate I-beams placed at different heights, a slot 42 is provided at the lower end of the upper plate 41, and the upper end of the lower plate 44 is inserted into the slot 42. An adjusting screw 43 is also provided on the side of the upper plate 41, with its lower end threaded through the lower plate 44. When spraying I-beams placed at different heights, the operator can adjust the height of the upper plate 41 by rotating the adjusting screw 43. Since the support frame 8 is connected to the upper plate 41, the height of the spray nozzle 61 is also adjusted. An insert plate 45 is provided at the lower end of the lower plate 44, and a slot 14 is provided on the end face of the base plate 1. A pressing bolt is threaded through the side wall of the slot 14. After the insert plate 45 is inserted into the base plate 1, the pressing bolt can be rotated to control the lifting plate assembly 4 to be stably installed on the base plate 1. This provides convenience for adjusting the position of the lifting plate assembly 4 relative to the base plate 1 as needed, improving the practicality of the device.

[0043] like Figures 1-16 As shown, to cope with the inclined installation on the I-beam, the support frame 8 includes a connecting plate 81, a central shaft 82, a limiting ring plate 83, a spring 84, and a stop plate 86. The central shaft 82 is installed through the upper end of the upper plate 41. The connecting plate 81 is installed at the end of the central shaft 82 and is hinged to the inclined brace plate 51. The limiting ring plate 83 is sleeved on the central shaft 82 (specifically, the inner end face of the limiting ring plate 83 and the central shaft 82 can both be set as concave and convex structures). Multiple limiting posts 85 are provided on the side wall near the upper plate 41. The limiting posts 85 are inserted into the limiting grooves 46 of the upper plate 41. With the cooperation of the limiting posts 85 and the limiting grooves 46, the central shaft 82 can be stably and vertically installed relative to the upper plate 41, thereby controlling the nozzle 61 to be in a stable working state. Spring 84 and stop plate 86 are mounted on central shaft 82 and located on the side of limiting ring plate 83 away from upper plate 41. Stop plate 86 is threadedly connected to the end of central shaft 82. Spring 84 is sleeved on central shaft 82, with both ends connected to stop plate 86 and limiting ring plate 83 respectively, and is in a compressed state. Under the action of spring 84, the limiting ring plate 83 is pressed and stably attached to upper plate 41, while providing convenience for staff to adjust the tilt of nozzle 61. Example 2

[0044] like Figures 1-16As shown, a spray nozzle guide device for spraying steel structure surfaces includes a spray guide assembly 2. The spray guide assembly 2 includes a spraying mechanism 6, a support mechanism 5, a lifting plate assembly 4, and multiple guide plates 7. The lifting plate assembly 4 includes an adjustable upper plate 41 and a lower plate 44. The lower plate 44 is set on a base plate 1 to provide support for the operation of the spray guide assembly 2. The multiple guide plates 7 are connected end to end to form a ring structure. The support mechanism 5 is set at the upper end of the upper plate 41. The ring formed by the guide plates 7 can pass through the support mechanism 5 and can be controlled to rotate around the axis under the action of the support mechanism 5. The spraying mechanism 6 includes a spray nozzle 61, which is set inside the ring and perpendicular to the ring. A caster wheel is installed below the base plate 1. A sprayer 11, a storage cylinder 13, and a push handle 12 are mounted on the base plate 1. The storage cylinder 13 stores paint, and its feed port is connected to the feed end of the sprayer 11. The feed end of the sprayer 11 is connected to the nozzle 61 via a pipe. Therefore, before spraying the H-beam, the guide plates 7 are disassembled and assembled as needed, so that the guide plates 7 are fitted onto the outside of the H-beam. When the sprayer 11 is working, it can deliver paint to the nozzle 61 and spray it onto the H-beam, achieving the spraying treatment of the H-beam. During the spraying process, the support mechanism 5 controls the guide plates 7 to rotate back and forth, achieving spraying of multiple sides at the same location. During the spraying of the H-beam, the operator can move the base plate 1 according to the spraying progress to ensure comprehensive spraying of the H-beam. This setup changes the previous situation where lifting equipment was needed to move the I-beams or the direction of the spray nozzles 61 needed to be adjusted multiple times, thus improving the spraying efficiency of the I-beams and reducing the labor intensity of the workers.

[0045] like Figures 1-16 As shown, in order to facilitate the fitting of the ring composed of guide plates 7 onto the I-beam, in this scheme, six guide plates 7 are provided, and each guide plate 7 has a connecting groove 72 at the end of its outer side. A connecting plate 73 can be detachably installed in the space formed by adjacent connecting grooves 72. For example, the connecting plate 73 and the guide plate 7 can be connected by connecting bolts. This arrangement allows the staff to easily disassemble two guide plates 7 according to actual needs, thus forming a notch on the ring. The width of the notch is greater than the width of the I-beam. Therefore, the ring can be fitted onto the I-beam from the side.

[0046] like Figures 1-16As shown, in order to connect the nozzle 61 to the guide plate 7, an installation groove 74 is provided on the inner side of a certain guide plate 7. At the same time, a sleeve 63, a connecting rod 65, and an end plate 66 are vertically arranged on the side of the nozzle 61. The sleeve 63 is sleeved on the connecting rod 65, and the end of the fastening bolt with thread through the sleeve 63 presses against the side wall of the connecting rod 65. In order to ensure that the connecting rod 65 and the sleeve 63 are relatively stationary, the inner end face of the sleeve 63 and the end face of the connecting rod 65 are both set as concave and convex structures. In this case, it can be ensured that the nozzle 61 is stable and perpendicular to the guide plate 7. The end plate 66 is located at the end of the connecting rod 65, and the end plate 66 is detachably installed in the installation groove 74. For example, the end plate 66 is connected in the installation groove 74 by a connecting bolt. Two symmetrical arc-shaped clamps 64 are provided at the end of the sleeve 63. Each arc-shaped clamp 64 has a limiting rod on its inner side. The nozzle 61 has a limiting groove 62 that runs through the space formed by the two arc-shaped clamps 64. The limiting rod is located in the limiting groove 62. With the cooperation of the limiting groove 62 and the limiting rod, the nozzle 61 is stably placed relative to the sleeve 63.

[0047] like Figures 1-16 As shown, to ensure the stability and rotatability of the ring formed by the guide plates 7 on the side of the support mechanism 5, the support mechanism 5 includes a support frame 8, two sets of inclined bracing plates 51, a bidirectional screw 53, two drive shafts 52, and two arc-shaped plates 55. The two sets of inclined bracing plates 51 are symmetrically arranged on the side of the support frame 8 and are hinged to the support frame 8. The two drive shafts 52 are connected to the two sets of inclined bracing plates 51 one by one, and are threaded onto both ends of the bidirectional screw 53. The bidirectional screw 53 is also connected to the support frame 8. Therefore, when the adjustment is rotated... When the screw 43 is adjusted, the included angle of the two sets of inclined support plates 51 can be adjusted. Two arc-shaped plates 55 are respectively hinged to the ends of the two sets of inclined support plates 51, and the cross-section is set as a U-shaped structure. A roller 56 is set on the arc-shaped plate 55. A drive gear 54 is installed through one of the arc-shaped plates 55. The drive gear 54 is connected to the drive motor. The guide plate 7 is set through the arc-shaped plate 55. The roller 56 is in rolling contact with the inner side of the guide plate 7. The outer side of the guide plate 7 is provided with tooth grooves 71. The drive gear 54 meshes with the tooth grooves 71. Under the action of the roller 56, the ring formed by the guide plates 7 is stably and movably installed through the arc-shaped plate 55, without affecting the rotation of the ring formed by the guide plates 7. When the H-beams forming a ring through the guide plates 7 are being sprayed, the drive motor rotates regularly in both directions, thereby controlling the drive gear 54 to rotate. Since the drive gear 54 is meshed with the guide plates 7, it controls the guide plates 7 to drive the spray nozzle 61 to make regular circular motions, achieving complete spraying of the side of the H-beams. When spraying H-beams of different sizes, guide plates 7 of different sizes can be replaced. In order to stably support guide plates 7 of different sizes, the operator can rotate the bidirectional screw 53 to adjust the tilt angle of the inclined support plate 51, thereby adjusting the position of the arc plate 55 to stably clamp the ring formed by the guide plates 7.

[0048] like Figures 1-16 As shown, to accommodate I-beams placed at different heights, a slot 42 is provided at the lower end of the upper plate 41, and the upper end of the lower plate 44 is inserted into the slot 42. An adjusting screw 43 is also provided on the side of the upper plate 41, with its lower end threaded through the lower plate 44. When spraying I-beams placed at different heights, the operator can adjust the height of the upper plate 41 by rotating the adjusting screw 43. Since the support frame 8 is connected to the upper plate 41, the height of the spray nozzle 61 is also adjusted. An insert plate 45 is provided at the lower end of the lower plate 44, and a slot 14 is provided on the end face of the base plate 1. A pressing bolt is threaded through the side wall of the slot 14. After the insert plate 45 is inserted into the base plate 1, the pressing bolt can be rotated to control the lifting plate assembly 4 to be stably installed on the base plate 1. This provides convenience for adjusting the position of the lifting plate assembly 4 relative to the base plate 1 as needed, improving the practicality of the device.

[0049] like Figures 1-16 As shown, to cope with the inclined installation on the I-beam, the support frame 8 includes a connecting plate 81, a central shaft 82, a limiting ring plate 83, a spring 84, and a stop plate 86. The central shaft 82 is installed through the upper end of the upper plate 41. The connecting plate 81 is installed at the end of the central shaft 82 and is hinged to the inclined brace plate 51. The limiting ring plate 83 is sleeved on the central shaft 82 (specifically, the inner end face of the limiting ring plate 83 and the central shaft 82 can both be set as concave and convex structures). Multiple limiting posts 85 are provided on the side wall near the upper plate 41. The limiting posts 85 are inserted into the limiting grooves 46 of the upper plate 41. With the cooperation of the limiting posts 85 and the limiting grooves 46, the central shaft 82 can be stably and vertically installed relative to the upper plate 41, thereby controlling the nozzle 61 to be in a stable working state. Spring 84 and stop plate 86 are mounted on central shaft 82 and located on the side of limiting ring plate 83 away from upper plate 41. Stop plate 86 is threadedly connected to the end of central shaft 82. Spring 84 is sleeved on central shaft 82, with both ends connected to stop plate 86 and limiting ring plate 83 respectively, and is in a compressed state. Under the action of spring 84, the limiting ring plate 83 is pressed and stably attached to upper plate 41, while providing convenience for staff to adjust the tilt of nozzle 61.

[0050] like Figures 1-16As shown, to reduce the labor intensity of manually moving the device during the spraying process, a walking assembly 3 is provided on the side of the base plate 1. The walking assembly 3 includes walking wheels 32, a bracket, and a walking motor 31. The walking wheels 32 are mounted on the bracket and connected to the output shaft of the walking motor 31, so the walking wheels 32 can be rotated when the walking motor 31 is working. A snap-fit ​​plate 33 is provided at the end of the bracket, and the snap-fit ​​plate 33 is fitted onto a vertical plate 35. The vertical plate 35 is mounted on the base plate 1 and has a sliding groove on its side. A threaded post 36 is provided in the sliding groove, and an internally threaded tube 34 located inside the snap-fit ​​plate 33 is located in the sliding groove, with the threaded post 36 threaded through the internally threaded tube 34.
