Description

Technical Field

[0001] The invention relates to the field of spraying equipment, in particular to an all-round automatic spraying equipment for steel structures. Background Art

[0002] The spraying operation in the steel structure production process is mainly to prevent the influence of oxidation corrosion of steel in the air on the strength and structure, and also for the purpose of aesthetics. The traditional spraying method is to manually use a pneumatic spray gun to manually spray the surface of the component in all directions by adjusting the air pressure. This method is inefficient, wastes a lot of paint, and causes great damage to the operator's body, which is very likely to cause occupational hazards; The Chinese invention patent with the announcement number CN112138907A discloses a steel structure painting device. By designing the fixed ring sleeve and the rotating ring to rotate relative to each other, the nozzle installed on the rotating ring can rotate around the steel structure to spray, and translate along the steel structure at the same time, thereby realizing automatic painting of the steel structure; the existing painting device has at least the following three defects: first, for relatively large steel components, the painting device will also be relatively bulky. The existing use of a lead screw nut pair to drive the painting device to translate along the axial direction of the steel component not only has a low bearing capacity and is not stable enough, but also has a slow moving speed, and the number of nozzles is set to be small, which will further affect the painting efficiency; second, the rotating ring of the existing device needs to be put on the middle section of the steel component in advance, and then the two ends of the steel component are supported, resulting in the need to hoist the steel component all the time during the sleeve process, which is very troublesome, and the two ends of the steel component cannot be automatically sprayed in place due to the support obstruction; third, the spraying distance between the steel component and the nozzle cannot be adjusted adaptively, so only a small number of specific steel parts can be sprayed, and the adaptability is poor. Summary of the invention

[0007] Furthermore, two driving gears are spaced apart in the installation box, each driving gear is coaxially fixed with a driven sprocket, a driving sprocket that can be connected through a chain ring transmission is provided between the two driven sprockets, and the output shaft of the control motor is coaxially fixed with the wheel axle of the driving sprocket.

[0008] Furthermore, the connecting rod is configured as a telescopic pole.

[0017] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the devices or components referred to must have a specific direction: Combined with Figure 1-4 The steel structure all-round automatic spraying equipment comprises a groove-type rail 2, a vertically arranged telescopic cylinder 3 and two spaced-apart rails 10, and a door frame 1 composed of a horizontal brace and two vertical braces. A sliding rod 8 is slidably mounted in the groove-type rail 2. Specifically, the groove width of the groove-type rail 2 is less than the distance between the two groove walls, and the width of the sliding rod 8 is slidably adapted to the distance between the two groove walls of the groove-type rail 2; the groove-type rail 2 and the sliding rod 8 are both arc-shaped with a central angle greater than 180 degrees, ensuring that the sliding rod 8 will not slip off the groove-type rail 2; but the center angle of the groove-type rail 2 The larger the angle, the smaller the gap, which is not conducive to moving the cover from the top of the steel part. Therefore, it is necessary to limit the central angle of the grooved rail 2 to less than 250 degrees, and 240 degrees is generally the best, so that no matter what position the slide bar 8 is rotated to, more rods are clamped in the grooved rail 2, and the central angle of the slide bar 8 is smaller than the central angle of the grooved rail 2, so that when not in use, the slide bar 8 can be completely hidden in the grooved rail 2 for protection; the grooved rail 2 is correspondingly arranged in the door frame 1 with the notch inward, and the grooved rail 2 itself is also C-shaped or door-shaped. The two ends of the telescopic cylinder 3 are respectively fixedly connected to the middle part of the cross brace and the middle part of the outer bottom of the groove-shaped transfer rail 2. The telescopic cylinder 3 can be used to control the groove-shaped transfer rail 2 to rise and fall and adjust the positioning according to the spraying distance. According to needs, two telescopic cylinders 3 are arranged side by side and are both hydraulic cylinders to improve the connection strength and bearing capacity. The cylinder body of the telescopic cylinder 3 is fixed to the cross brace, and the telescopic rod end of the telescopic cylinder 3 slides through the cross brace and is fixedly connected to the groove-shaped transfer rail 2 to ensure that the lifting height of the groove-shaped transfer rail 2 is not limited by the cylinder body of the telescopic cylinder 3. The bottom ends of the two vertical braces are correspondingly clamped on the two The track 10 can be moved and positioned along the track 10. Specifically, a walking wheel controlled by a servo motor can be installed at the bottom of the vertical support member, which is convenient for movement control. Even without the track 10, the entire device can be directly moved out of the track 10 and moved to the top of the steel part that needs to be sprayed for spraying; the inner sides of the two vertical support members are provided with vertical slide rails, and the vertical slide rails are equipped with sliders 6 that can be moved and positioned along the vertical slide rails. Each slider 6 is connected to the corresponding end of the groove-type transfer rail 2 with an installation box 7. The slide rails and the sliders 6 cooperate to guide the groove-type transfer rail. 2 Lifting is stable; a driving gear 9 is rotatably installed in the installation box 7, and a control motor that drives the driving gear 9 to rotate is installed, and a rack 13 is provided on the arc-shaped outer wall surface of the slide bar 8. The driving gear 9 is correspondingly cut into the groove-type transfer rail 2 and meshes with the rack 13. The driving gear 9 is controlled by the control motor to rotate, and then the rack 13 and the slide bar 8 are driven to move along the groove-type transfer rail 2, forming an overall large rotation control around the steel member. Of course, the two control motors in the two installation boxes 7 must be linked and synchronously driven and controlled; according to needs, two driving gears 9 are arranged in the installation box 7 at intervals, each driving gear 9 is coaxially fixed with a driven sprocket 17, and a driving sprocket 15 that can be connected by a chain ring 16 is provided between the two driven sprockets 17. The output shaft of the control motor is coaxially fixed with the wheel axle of the driving sprocket 15, and the two driving gears 9 are controlled to rotate by a control motor, and the four driving gears 9 can not only fix the slide bar 8 with the rack 13 and stabilize the transmission, but also ensure that there are always at least three driving gears 9 meshing and controlling during the rotation of the slide bar 8; A plurality of connecting rods 4 are evenly spaced along the arc-shaped rod body of the slide bar 8. The connecting rods 4 can be detachably connected to the slide bar 8, or can be designed to be positionally adjustable on the slide bar 8. As needed, four connecting rods 4 are provided and symmetrically arranged at both ends of the slide bar 8, and the center angle between two adjacent connecting rods 4 is 60 degrees, so that it can correspond to both sides of the steel part and the top surface of the steel part. In addition, the connecting rods 4 are configured as telescopic poles, and the rod body of the slide bar 8 next to each telescopic pole is equipped with an infrared ranging device. Instrument 5, infrared rangefinder 5 is respectively connected with corresponding signals of control motor, telescopic pole and telescopic cylinder 3, and infrared rangefinder 5 is used to measure the distance to the steel part to be painted, so as to control and adjust the relative position and distance between the nozzle and the steel part, which greatly improves the self-controllability and adaptability; the bottom end of connecting rod 4 corresponds to the notch passing through the grooved turn rail 2 and is fixedly installed on sliding rod 8, and the head end of connecting rod 4 is installed with nozzle 14, and when sliding rod 8 rotates and moves, it can also drive nozzle 14 to perform circular spraying to ensure comprehensive spraying.

[0018] As needed, the outer wall of the lower end of the installation box 7 is connected to a hanging rod 12, and a horizontal cantilever rod 11 is fixed to the lower end of the hanging rod 12. A nozzle 14 is installed on the outer end of the cantilever rod 11. The cantilever rod 11 can also be set as a telescopic pole. An infrared rangefinder 5 can also be set next to the cantilever rod 11. It is mainly aimed at steel parts that do not need to be painted on the bottom surface and are relatively high, especially steel parts that are heavy and not conducive to lifting, and can only be placed on the ground. The added cantilever rod 11 can improve the spraying efficiency and convenience.

[0019] As needed, the front of the door frame 1 is connected to a first door frame 18, and the inner frame wall of the first door frame 18 is provided with a cleaning device for cleaning the surface of the sprayed parts. Specifically, multiple jet pipes can be arranged along the first door frame 18 to use high-pressure gas to clean the surface of the steel parts to be painted. In addition, the rear of the door frame 1 is connected to a second door frame 19, and the inner frame wall of the second door frame 19 is provided with a drying device for drying the surface of the sprayed parts. The drying device can be set as a heating element such as an electric heating wire.

[0020] When implementing the all-round automatic spraying equipment for steel structures described in the present invention, after the steel parts to be painted are supported between the two rails 10, the door frame 1 can be controlled to move above the end of the steel parts, and then the telescopic cylinder 3 is adjusted to control the lifting and lowering of the grooved rail 2, thereby adjusting the distance between the spray head 14 and the surface of the steel parts. After the adjustment is in place, the drive motor and the paint supply device connected to the spray head 14 with a hose are started, and then the slide bar 8 can be controlled to rotate and spray. While spraying, the movement of the door frame 1 is controlled. When it moves to the support at the bottom of the steel parts, most of the slide bar 8 is moved and hidden in the grooved rail 2 until it passes the bottom support, and then the rotation is controlled to perform circumferential spraying. If the steel parts do not need to be painted on the bottom, there is no need to control the rotation of the slide bar 8.
