However, many of the facades of box girders are special-shaped structures, so the spraying of box girders is usually done manually. However, manual spraying easily leads to inconsistent distances between the nozzle and the facade of the box girder, resulting in poor spraying uniformity, and manual spraying is not efficient, and increases the economic cost of production. Summary of the invention

[0005] The invention provides a box girder spraying device and process, aiming to solve the technical problems in the related art that the uniformity of manual spraying is poor and the efficiency of manual spraying is low.

[0006] A box beam spraying device of the present invention comprises: a bottom plate, a liquid storage tank is arranged on the top of the bottom plate, and the liquid storage tank contains paint, and further comprises: a box body, a driving component, a spraying module, and a limiting component.

[0008] The spraying module is rotatably arranged on the fixing frame and is connected to the liquid storage tank. The spraying module can spray paint on the box beam. The spraying module is provided with a first push rod and a second push rod arranged up and down. The first push rod and the second push rod are in a V-shaped structure. The first push rod and the second push rod are used to contact the surface of the box beam to be sprayed.

[0009] The driving component drives the spray module to move toward the workpiece so that the first push rod and the second push rod contact the surface of the box beam to be sprayed, and at the same time drives the spray module to move in the vertical direction, so that the first push rod on the spray module and the second push rod on the adjacent spray module are close to the two ends in contact with the box beam. The limiting components are arranged on both sides of the spray module for limiting the spray angle after the spray module is adjusted.

[0010] The beneficial effects of the present invention are as follows: the spraying module can position and adjust the angle of the surface to be sprayed of the special-shaped box beam, so that the spraying module can be perpendicular to the spraying surface, and at the same time, each spraying module is at an equal distance from the surface to be sprayed, thereby making the spraying effect more uniform.

The first guide rod and the second guide rod are arranged on the upper length direction of the two guide plates, and the ends of the first guide rod and the second guide rod that are close to each other extend to the interior of the limit box, and sliding bars are arranged on the first guide rod and the second guide rod, and the sliding bars can slide with the guide grooves.

[0015] Preferably, the first push rod and the second push rod are respectively arranged at one end of the first guide rod and the second guide rod away from each other and are connected by bolts. The first guide rod and the second guide rod are both provided with elastic components, which can elastically support the first guide rod and the second guide rod, so that there is a contact-breaking gap between the first guide rod and the second guide rod and the contactor.

[0016] The effect is that after the first guide rod and the second guide rod contact the box beam, the angle of the spraying module is locked, thereby improving the spraying effect and uniformity.

[0017] Preferably, the elastic component includes a plurality of springs, and the plurality of springs are arranged on the upper and lower sides of the limit box, with two springs on each side. Fixed plates are arranged on the two opposite side walls of the first guide rod and the second guide rod, and the springs are connected to the fixed plates, so that the springs always support the fixed plates in the initial state, so that the first guide rod and the second guide rod are in a separated state from the contactor.

[0018] Preferably, a spray head is provided on one side of the spray module, and a spray hole is opened on one side of the spray head.

[0019] The effect is that the spraying range can be changed by adjusting the aperture according to the special-shaped surface of the box beam, thereby improving the flexibility of spraying.

[0023] A box beam spraying process, using the above box beam spraying equipment, comprises the following steps:

[0024] S1. The driving assembly can push multiple spray modules to move toward the box beam in sequence. The movement of the spray modules drives the first push rod and the second push rod to move. Since the surface of the box beam to be sprayed is a special-shaped surface, one of the first push rod and the second push rod contacts the box beam first.

[0025] S2, therefore, the driving assembly pushes the spraying module again to move toward the box beam, thereby forcing the spraying module to adjust its angle, and the spraying module angle adjustment makes the first push rod and the second push rod both contact the box beam;

[0026] S3, when both the first push rod and the second push rod are in contact with the box beam, the limiting assembly can be triggered so that the limiting assembly limits the spraying angle adjusted by the spraying module.

[0027] The beneficial effects of the present invention are as follows: the spraying module can be positioned and the angle adjusted with respect to the spraying surface, so that the spraying module can be perpendicular to the spraying surface, and at the same time, each spraying module is at an equal distance from the spraying surface, and the device prevents the spraying ranges of multiple nozzles from interacting, thereby making the spraying effect more uniform.

[0028] The beneficial effects of the present invention are:

[0029] When in use, due to the spraying of the special-shaped box girder structure, the driving component drives the first fixed frame and the spraying module to move, and the movement of the first spraying module drives the first push rod and the second push rod to move toward the surface of the box girder to be sprayed. Since the surface of the special-shaped box girder to be sprayed is a special-shaped surface, when the first push rod first contacts the surface of the box girder to be sprayed, the driving component continues to push the spraying module, so that the spraying module rotates with the rotating connection of the fixed frame as the fulcrum, thereby adjusting the angle of the spraying module, so that when the second push rod stops with the surface of the box girder to be sprayed, the limiting component fixes the rotation angle of the spraying module, and each group of the first push rod and the second push rod contacts the spraying surface of the special-shaped box girder in turn, so as to position the spray module and adjust the angle, so that the spray module can be perpendicular to the spraying surface, thereby making the spraying effect more uniform.

[0030] During use, since the first push rod and the second push rod are in contact with the box beam, the distance between each nozzle and the box beam is always consistent. At the same time, the positioning of the first push rod and the second push rod avoids the intersection of the spraying ranges of multiple nozzles, thereby improving the uniformity of spraying. At the same time, the problem of manual spraying of special-shaped box beams is solved, thereby improving the efficiency of spraying. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0043] like Figures 1 to 9 As shown, a box beam spraying device of the present invention comprises a bottom plate 10, a fixing frame 53, a spraying module 50, a driving assembly, and a spray head 56. A liquid storage tank 11 and a box body 20 are arranged on the top of the bottom plate 10. The liquid storage tank 11 contains a spraying liquid for spraying the box beam. A plurality of fixing frames 53 are arranged at intervals on one side of the box body 20 in a longitudinal direction. The fixing frames 53 have a plurality of fixing frames 53, and the fixing frames 53 are U-shaped structures. The driving assembly is arranged inside the box body 20, and the driving assembly is connected to the fixing frames 53 in a transmission manner so that the driving assembly can be driven by the fixing frames 53. The moving component can drive the fixed frame 53 to extend or move up and down in turn. The spray module 50 is rotatably set at the U-shaped opening of the fixed frame 53. The spray module 50 can be rotated up and down to adjust the angle. The nozzle 56 is set on the outer wall of one side of the spray module 50. The first push rod 70 and the second push rod 71 are set on the spray component. The first push rod 70 and the second push rod 71 are used to contact the surface of the box beam to be sprayed. Limiting components are set on the left and right sides of the spray module 50 for limiting the spraying angle after the spray module 50 is adjusted.

[0044] When spraying the special-shaped box beam structure, the driving assembly drives the first fixing frame 53 and the spraying module 50 to move, and the first spraying module 50 moves to drive the first push rod 70 and the second push rod 71 to move toward the surface of the box beam to be sprayed. Figure 7 and Figure 8 As shown in the figure), when the first push rod 70 first contacts the surface of the box beam to be sprayed, the driving assembly continues to push the spray module 50, so that the spray module 50 rotates with the rotating connection of the fixed frame 53 as the fulcrum, thereby adjusting the angle of the spray module 50, so that when the second push rod 71 stops at the surface of the box beam to be sprayed, the limiting assembly fixes the rotation angle of the spray module 50, and each group of the first push rod 70 and the second push rod 71 positions and adjusts the angle of the spray surface of the special-shaped box beam in turn, and at the same time avoids the intersection of the spraying ranges of multiple nozzles 56, thereby improving the uniformity of spraying, replacing manual spraying, and improving the efficiency of spraying.

[0045] like Figures 2 to 4 As shown, the outer walls of the left and right sides of the spray module 50 are provided with a rotating shaft 51 (as shown in FIG. Figure 4As shown), the two rotating shafts 51 extend to the left and right sides respectively, and the extended ends of the two rotating shafts 51 are rotatably connected to the fixing frame 53. The outer cylindrical surface of the rotating shaft 51 is provided with a torsion spring 55, and the torsion spring 55 can reset the spraying angle of the spray module 50. The opposite side walls of the fixing frame 53 are provided with sleeves 54, and the sleeves 54 are connected with the torsion spring 55 to make the initial state of the spray module 50 horizontal. A limiting gear 52 is provided on the outer peripheral surface of the rotating shaft 51, and the limiting gear 52 can cooperate with the limiting assembly to limit and fix the rotating shaft 51 to achieve the function of fixing the spray module 50, so that the spraying is more stable and the spraying effect is better.

[0046] Since the surface of the box beam to be sprayed may be an irregular surface, when the spraying angle of the spray module 50 needs to be adjusted, the spray module 50 is rotated with the rotating shaft 51 as the fulcrum. At the same time, the rotation of the spray module 50 drives the rotating shaft 51 and the limiting gear 52 to rotate. The rotation of the rotating shaft 51 drives the torsion spring 55 to deform, so that the torsion spring 55 is deformed inside the sleeve 54. When the first push rod 70 and the second push rod 71 contact the box beam at the same time, the limiting assembly will be triggered to limit the limiting gear 52, thereby limiting the rotating shaft 51, so as to achieve the limit and fixation of the spray module 50 after adjustment.

[0047] like Figures 2 to 3 As shown, the limit assembly includes a limit box 60, a contactor 61, and an electric extension rod 66. The limit box 60 is arranged on the left and right side walls of the spray module 50. The interior of the limit box 60 is a hollow structure. The contactor 61 is arranged inside the limit box 60 and is arranged along the length direction of the limit box 60. There are two switch contacts on the contactor 61, and the two contacts need to be in contact at the same time to close and energize. The electric extension rod 66 is arranged on one side of the limit box 60, and one end of the electric extension rod 66 is connected to the contactor 61. When the contactor 61 is energized, the electric extension rod 66 can be driven to extend. A card 67 is provided at the other end of the electric extension rod 66, and the card 67 can cooperate with the limit gear 52 to limit and fix the rotating shaft 51.

[0048] Two guide plates 63 are vertically arranged on the left and right side surfaces of the spray module 50. The two guide plates 63 are symmetrically arranged with the contactor 61 as the symmetry axis, and the two guide plates 63 are perpendicular to the limit box 60. Guide grooves are arranged on the guide plates 63. The first guide rod 62 and the second guide rod 68 are arranged on the two guide plates 63 along the length direction. The ends of the first guide rod 62 and the second guide rod 68 that are close to each other extend to the inside of the limit box 60, and the first guide rod 62 and the second guide rod 68 are provided with sliding bars, and the sliding bars can slide with the guide grooves so that the first guide rod 62 and the second guide rod 68 can slide up and down along the length direction of the guide plates 63. The first push rod 70 and the second push rod 71 are respectively arranged at the ends of the first guide rod 62 and the second guide rod 68 that are away from each other, and are connected by bolts. The first guide rod 62 and the second guide rod 68 are provided with elastic components, which can elastically support the first guide rod 62 and the second guide rod 68, so that there is a contact-breaking gap between the first guide rod 62 and the contactor 61.

[0049] When the driving assembly drives the spray module 50 to move closer to the box beam, when the first push rod 70 first contacts the surface of the box beam to be sprayed, the spray module 50 is adjusted in angle, and at the same time, the first push rod 70 will push the first guide rod 62 in the opposite direction to move the first guide rod 62 from top to bottom, so that the first guide rod 62 extends to one end of the limit box 60 to squeeze a limit contact of the contactor 61.

[0050] When the second push rod 71 contacts the surface of the box beam to be sprayed, the second push rod 71 will drive the connected second guide rod 68 to move from bottom to top, so that the second guide rod 68 squeezes the second limit contact of the contactor 61. When the two limit contacts are squeezed at the same time, the contactor 61 will control the electric push rod 66 to move. The movement of the electric push rod 66 drives the card 67 to move, so that the card 67 is inserted into the limit gear 52, thereby realizing the spraying angle limit of the spray module 50 after adjustment. The first push rod 70 and the second push rod 71 can make the distance between the nozzle 56 and the surface of the box beam to be sprayed consistent, thereby ensuring the uniformity of spraying of multiple nozzles 56 and improving the uniformity of spraying.

[0051] like Figure 2 As shown, when both ends of the first push rod 70 and the second push rod 71 are in contact with the box beam and the spraying angle is fixed, the special-shaped box beam surface can be sprayed. At the same time, the ends of the two push rods are provided with ball bearings to facilitate the first push rod 70 and the second push rod 71 to move on the box beam surface to be sprayed during spraying. After the spraying is completed, the first push rod 70 and the second push rod 71 are separated from the box beam surface, and at the same time, the contactor 61 will control the electric push rod 66 to retract and move. The movement of the electric push rod 66 drives the card 67 to move, so that the card 67 is separated from the limit gear 52 and the limit is released, so that the torsion spring 55 can reset the spray angle of the spray module 50.

[0052] like Figure 3 As shown, the elastic component includes a spring 65, and multiple springs 65 are arranged on the upper and lower sides of the limit box 60, with two springs on each side. A fixing plate 64 is arranged on the two opposite side walls of the first guide rod 62 and the second guide rod 68, and the spring 65 is connected to the fixing plate 64, so that the spring 65 always supports the fixing plate 64 in the initial state, thereby realizing the elastic support of the spring 65 to the first guide rod 62 and the second guide rod 68, so that the first guide rod 62 and the second guide rod 68 are in a separated state from the contactor 61.

[0053] like Figures 2 to 5 As shown, a spray head 56 is provided on one side of the spray module 50, and a spray hole 57 is opened on one side of the spray head 56. The spray module 50 can be adjusted to improve the flexibility of spraying, while avoiding inconsistent thickness of the cross-spraying parts of multiple spray heads 56, thereby improving the uniformity of spraying.

[0054] like Figures 5 and 6 As shown, the driving assembly includes a first motor 21, which is arranged on the top of the box body 20, and a first rotating rod 22 is arranged at the output end of the first motor 21. A support plate 25 is arranged inside the box body 20, and one end of the first rotating rod 22 is rotatably connected to the support plate 25, and a first bevel gear 23 is arranged on the outer peripheral surface of the first rotating rod 22. Two second motors 30 are arranged from bottom to top inside the box body 20, and the output ends of the two second motors 30 are both provided with first rotating rods 22, and a first bevel gear 23 is arranged on the outer peripheral surface of each first rotating rod 22.

[0055] like Figures 5 to 9 As shown, a plurality of fixed columns 40 are arranged on the box body 20, and a transmission groove 43 is opened on the outer circumference of each fixed column 40. Each fixed column 40 vertically penetrates the box body 20, and a moving rod 41 is slidably arranged inside the fixed column 40 along the axial direction. The moving rod 41 can slide inside the fixed column 40, and a tooth 42 is arranged on the top surface of the moving rod 41. A second support plate 45 is arranged inside the box body 20, and a rotating rod 46 is arranged on the second support plate 45. A second gear 47 is arranged at one end of the rotating rod 46. The second gear 47 is arranged at one end of the rotating rod 46. The gear 47 is meshed with the teeth 42 to enable the moving rod 41 to slide axially along the fixed column 40. A second bevel gear 48 is provided at the other end of the rotating rod 46. The second bevel gear 48 is meshed with the first bevel gear 23. L-shaped support plates 80 are provided on the outer walls of both sides of the moving rod 41. A telescopic rod 81 is provided on the L-shaped support plate 80. A connecting plate 82 is provided on the side of the fixed frame 53 facing the moving rod 41, and the top of the telescopic rod 81 is connected to the bottom surface of the connecting plate 82, so that the fixed frame 53 can slide up and down.

[0056] When the spraying range and angle of the spray module 50 are adjusted in turn, the first motor 21 drives the first rotating rod 22 to rotate clockwise, and the first rotating rod 22 rotates clockwise to drive the top first bevel gear 23 to rotate, and the first bevel gear 23 is meshed with the second bevel gear 48. Therefore, the rotation of the first bevel gear 23 drives the second bevel gear 48 to rotate, and the rotation of the second bevel gear 48 drives the rotating rod 46 to rotate. The rotation of the rotating rod 46 drives the second gear 47 to rotate, and the second gear 47 is meshed with the teeth 42. Therefore, the rotation of the second gear 47 drives the moving rod 41 to move, and the movement of the moving rod 41 drives the fixed frame 53 to move, thereby realizing the top extension movement of the spray module 50, and adjusting the spraying angle of each spray module 50 in turn, and the driving structure of each spray module 50 is consistent, which will not be repeated here.

[0057] like Figure 6 As shown, a through hole 44 is opened inside the fixed column 40 along the axial direction, and the through hole 44 runs through both ends of the fixed column 40. Telescopic hoses 49 are connected to both ends of the fixed column 40. One telescopic hose 49 is connected to the liquid storage tank 11, and the other telescopic hose 49 is connected to the spray module 50. The telescopic hose 49 can move with the spray module 50 to perform telescopic deformation.

[0058] like Figure 1 As shown, a pressure tank 13 is arranged on the top of the base plate 10, and a pressure pump 12 is arranged on the pressure tank 13. The pressure pump 12 pumps and pressurizes the pressure tank 13. At the same time, the output end of the pressure tank 13 is connected to the liquid storage tank 11, so that the inside of the liquid storage tank 11 can be pressurized, thereby improving the energy state of the fluid and making the fluid transportation and use process more efficient. A sliding groove 14 is provided at the bottom of the base plate 10, which can be used in conjunction with a slide rail, so that the entire device can perform uniform linear motion to ensure the stability of the spraying device during movement, thereby improving the uniformity of spraying.

[0059] A box beam spraying device applied to an embodiment of the present invention, and a spraying method thereof comprises the following steps:

[0060] S1. The driving assembly can push multiple spray modules 50 to move toward the box beam in sequence. The movement of the spray module 50 drives the first push rod 70 and the second push rod 71 to move. Since the surface of the box beam to be sprayed is a special-shaped surface, one of the first push rod 70 and the second push rod 71 contacts the box beam first.

[0061] S2, therefore, the driving assembly pushes the spray module 50 again to move toward the box beam, thereby forcing the spray module 50 to adjust its angle. The spray module 50 is adjusted so that both the first push rod 70 and the second push rod 71 are in contact with the box beam, so that the angle of the spray head 56 is perpendicular to the profiled surface of the box beam;

[0062] S3, when the first push rod 70 and the second push rod 71 are in contact with the box beam, the limiting assembly can be triggered so that the limiting assembly limits the spraying angle adjusted by the spraying module 50.

[0063] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0064] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
