Description

Technical Field

[0001] The utility model belongs to the technical field of painting, and relates to an adaptive gantry through-type section steel painting device. Background Technique

[0002] At present, the painting of existing section steels generally adopts the mode of a roller conveyor line. The section steel is conveyed forward through the roller conveyor, and the spraying is completed by a reciprocating machine spray gun device or by manual spraying. The disadvantages of the traditional painting roller conveyor line mode for section steels are as follows: (1) When the reciprocating machine spray gun device sprays, the spray gun is always in a moving state, which is likely to cause uneven spraying of the section steel; (2) The spraying size of the reciprocating machine spray gun device is relatively single and cannot be adjusted in real time according to the section steel specifications; (3) If manual spraying is adopted, the spraying quality completely depends on manual experience, and at the same time, it will inevitably cause the operators to contact harmful components such as paint, which will affect the health of the operators. Content of the Utility Model

[0003] In view of the technical problems existing in the background technique, the utility model provides an adaptive gantry through-type section steel painting device.

[0004] The technical solution for the utility model to solve the technical problems is as follows:

[0005] An adaptive gantry through-type section steel painting device of the utility model includes an outer gantry frame, and semi-spraying units are symmetrically suspended on the outer gantry frame. The semi-spraying unit includes a first track provided on the bottom surface of the top of the outer gantry frame. A connecting slider is movably arranged on the first track. The connecting slider is fixedly connected with an upper L-shaped frame body. The bottom end of the upper L-shaped frame body is connected with a second telescopic mechanism. The other end of the second telescopic mechanism is connected with a middle frame body. The other end of the middle frame body is connected with a third telescopic mechanism. The other end of the third telescopic mechanism is connected with a lower frame body. The inner side of the lower part of the lower frame body is connected with a fourth telescopic mechanism. The other end of the fourth telescopic mechanism is connected with a bottom frame body. Paint spray guns are respectively arranged on the inner side surfaces of the upper L-shaped frame body, the middle frame body, the lower frame body and the bottom frame body. A first telescopic mechanism is connected between the corresponding ends of the two upper L-shaped frame bodies.

[0006] Further, there are two paint spray guns on the upper L-shaped frame body, which are respectively vertically connected to the inner side surfaces of both ends of the upper L-shaped frame body through connecting frames; there is one paint spray gun on each of the middle frame body and the lower frame body, which are respectively vertically connected to the inner side surfaces of the middle frame body and the lower frame body through connecting frames; there is one paint spray gun on the bottom frame body, which is connected to the end surface of the bottom frame body through a connecting elbow frame.

[0007] Further, it further includes a conveying track disposed at the center below the outer gantry. A jig with a driving device is movably disposed on the conveying track, and the top of the jig is higher than the top of the paint spray gun on the bottom frame.

[0008] Further, it further includes a controller and a profile scanning device disposed at the conveying track and connected to the controller. The first telescopic mechanism, the second telescopic mechanism, the third telescopic mechanism, the fourth telescopic mechanism, and each of the paint spray guns are respectively connected to the controller.

[0009] Further, the profile scanning device is a grating scanning device.

[0010] Further, it further includes a first detection device and a second detection device disposed in front of the profile scanning device and connected to the controller. The distance between the first detection device and the second detection device is not less than 1 m.

[0011] Further, the first detection device and the second detection device are proximity switches or photoelectric sensors.

[0012] Further, a third detection device and a fourth detection device connected to the controller are respectively disposed on the front and rear sides of the outer gantry. The third detection device and the fourth detection device are preferably proximity switches or photoelectric sensors.

[0013] Further, it further includes a paint container. The paint container is connected to a paint piston pump through a main pipeline. The paint piston pump is respectively connected to each of the paint spray guns through a plurality of branch pipelines. Pressure stabilizing devices are respectively disposed on each of the branch pipelines. The paint piston pump and each of the pressure stabilizing devices are respectively connected to the controller.

[0014] Further, the pressure stabilizing device is a pressure stabilizing valve.

[0015] Compared with the prior art, an adaptive gantry through-type section steel painting device provided by the utility model has the following beneficial effects:

[0016] (1) The structure of the utility model is novel, simple, reasonable, and flexible. Two semi-spraying units symmetrically suspended on the outer gantry form a gantry structure, which is convenient for the section steel workpiece to pass through the gantry structure and be sprayed.

[0017] (2) The utility model forms a semi-spraying unit through an upper L-shaped frame body, a middle frame body, a lower frame body and a bottom frame body, and respectively arranges a second telescopic unit, a third telescopic unit and a fourth telescopic unit between the upper L-shaped frame body, the middle frame body, the lower frame body and the bottom frame body, and arranges a first telescopic unit between the upper L-shaped frame bodies of the two semi-spraying units. The distance between the four frame bodies and between the two upper L-shaped frame bodies can be adjusted through the four telescopic units, which is convenient for adjusting the spraying range of the paint spray guns installed on the four frame bodies, and thus convenient for spraying various specifications of profiled steel workpieces.

[0018] (3) The utility model is convenient for the conveying and spraying of profiled steel workpieces by arranging a conveying track and a jig on the conveying track.

[0019] (4) The utility model is convenient for scanning the profile of the profiled steel workpiece of the gantry through-type profiled steel coating equipment by arranging a profile scanning device on the conveying track, and adjusting each telescopic mechanism according to the scanning result, so that the spraying range of the paint spray guns on each frame body meets the requirements of profiled steel workpiece coating.

[0020] (5) The utility model is convenient for controlling the distance between adjacent two profiled steel workpieces by arranging a first detection device and a second detection device, ensuring the orderly progress of the coating operation.

[0021] (6) The utility model adjusts the distance between the four frame bodies through four telescopic mechanisms. When spraying the profiled steel workpiece, each paint spray gun is always in a fixed and non-moving state, which is convenient for the stability of spraying. When the profiled steel workpiece is evenly and slowly conveyed forward through the conveying track and the jig, through the paint plunger pump and the voltage stabilizing device, the paint spray gun can continuously spray out paint to evenly cover the surface of the profiled steel workpiece, effectively improving the spraying quality.

[0022] (7) The utility model does not require manual participation in the spraying operation, avoiding the contact between the operators and the harmful components of the paint. Description of the Drawings
