[0024] Further, in a specific embodiment, the overall structure of the spraying device may be as follows: A support connecting shaft 2 connected to the stroke mechanism 1 has a control mechanism installed at one end away from the stroke mechanism 1. A stretching mechanism is installed on the control mechanism, and a spray gun device 5 for spraying is installed on the stretching mechanism. The control mechanism includes a ball head seat 9, a first servo motor 7, and a shaft coupling 8. One end of the ball head seat 9 is movably connected to one end of the support connecting shaft 2 close to the ball head seat 9 through a ball head, and the other end of the ball head seat 9 is movably connected to a rotating shaft 15 through a ball head. The end of the rotating shaft 15 away from the ball head seat 9 is connected to the stretching mechanism. The first servo motor 7 is installed on the support connecting shaft 2, the output end of the first servo motor 7 is connected to the shaft coupling 8, and the shaft coupling 8 away from the first servo motor is rotatably connected to the rotating shaft 15 through a rotating seat. The first servo motor 7 drives the rotating shaft 15 to rotate through the shaft coupling 8, and the rotation of the rotating shaft 15 drives the spray gun device 5 installed through the stretching mechanism to spray the spraying workpiece lifted by the lifting mechanism installed on the tower crane.

[0025] Meanwhile, the set stretching mechanism includes a traveling guide beam 3 and a lead screw 12. The traveling guide beam 3 is movably connected to the rotating shaft 15 through a connecting structure. The traveling guide beam 3 is provided with a sliding groove, and the lead screw 12 is rotatably installed in the sliding groove through a bearing. The lead screw 12 is driven by a driving structure to move in the sliding groove. Connecting rods 13 are respectively connected to both ends of the traveling guide beam 3. One end of the connecting rod 13 away from the traveling guide beam 3 is connected to a spray gun device 5 for spraying through a cross bar 4; the connecting rod 13 is connected to the lead screw 12 rotatably installed in the sliding groove provided in the traveling guide beam 3 through a movable structure; moreover, the movable structure includes a movable connecting shaft. One end of the movable connecting shaft is connected to the connecting rod 13, and a sliding connecting seat is installed and connected to the other end of the movable connecting shaft. The sliding connecting seat is rotatably penetrated on the lead screw 12, and the sliding connecting seat is slidably adapted to the sliding groove provided in the traveling guide beam 12; meanwhile, the set driving structure includes a second servo motor 10. The second servo motor 10 is installed and connected to the traveling guide beam 12. A bevel gear is installed and connected to the output shaft end of the second servo motor 10. A gear 14 is installed and connected to the lead screw 12. The bevel gear meshes with the gear 14 installed and connected to the lead screw 12. And the traveling guide beam 12 is rotatably connected to one end of the rotating shaft 15 close to the traveling guide beam 12 through a bearing; a hydraulic rod 11 is installed and connected to the rotating shaft 15. The other end of the hydraulic rod 11 is connected to the traveling guide beam 12 through a hinge seat. Additionally, the set stroke mechanism 1 includes a first stroke unit driven and controlled by a servo motor and a second stroke unit driven and controlled by a servo motor. The first stroke unit is installed and connected to the support connecting shaft for driving the support connecting shaft to move, and the second stroke unit is installed and connected to the first stroke unit for driving the first stroke unit to move. Here, it should be noted that since this device works in a dust environment, a preferred implementation is to install and connect a protective cover at the sliding groove position to prevent dust from entering the sliding groove and affecting the use of the lead screw 12. And even if dust adheres to the lead screw 12 after long-term use, the protective cover can be removed at any time to clean, repair or even replace the lead screw 12; it is also possible to replace the lead screw 12 with other existing technologies that can achieve "telescopic translation", such as telescopic rods, hydraulic cylinders, etc., and the corresponding driving power source and driving connection method can be adjusted accordingly.

[0026] Further, in order to facilitate the control of the spraying device, a system for supporting use is designed. When the system is powered on, the spraying device moves to the standby position; the spraying workpiece, driven by the lifting mechanism, first passes through the recognition unit to record the contour data of the spraying workpiece and determine whether the spraying workpiece is close to the spraying device. If not, it waits for the spraying workpiece to approach the spraying device; if so, it converts the recorded contour data of the spraying workpiece into the coordinate data of the stroke mechanism 1 of the spraying device, and then the spraying device moves to the corresponding coordinate position, determines whether the spraying workpiece reaches the gun-firing position. If so, it turns on the spray gun for processing; otherwise, it waits for the spraying workpiece to reach the gun-firing position, determines whether the spraying workpiece reaches the gun-closing position of the spray gun device; if so, it closes the spray gun device, and the spraying device moves to the standby position, otherwise it continues processing, determines whether to end the system; if so, it ends the system, otherwise it returns, recognizes the spraying workpiece, and performs the spraying processing of the next round of spraying workpieces.

[0027] The spraying control system of the spraying device mainly consists of: an industrial control computer, an encoder, an identification unit, a spraying device, and a spray gun device installed and connected to the spraying device, etc. Among them, the encoder is installed on the conveying chain and is responsible for feeding back the movement amount of the conveying chain to the industrial control computer; the identification unit is not limited to using measurement gratings, laser scanners, visual recognition, etc., and is responsible for feeding back the contour dimension information of the workpiece to the industrial control computer; the spraying device is equipped with a stroke mechanism, which includes a first stroke unit driven and controlled by a servo motor and a second stroke unit driven and controlled by a servo motor. The first stroke unit is installed and connected to the support connecting shaft and is used to drive the support connecting shaft to move. The second stroke unit is installed and connected to the first stroke unit and is used to drive the first stroke unit to move; that is, in actual use, the first stroke unit is set as the Z-axis stroke unit driven by a high-precision servo motor, and the second stroke unit is set as the X-axis stroke unit driven by a high-precision servo motor. It should be noted here that in actual use, the first stroke unit and the second stroke unit can be interchanged, and only one of them is described here. The moving directions of the X-axis and Z-axis of the stroke mechanism are driven by high-precision servo motors, receive the coordinate movement values given by the industrial control computer, and drive the spray gun device 5 to move to the spraying position of the sprayed workpiece for spraying processing. During the spraying production of tower cranes, the spraying device is respectively installed at four positions on the upper and lower sides of both sides of the tower crane, that is, one stroke mechanism 1 is respectively set on both sides of the tower crane, and a spraying device that can be controlled by the stroke mechanism 1 is installed on both sides of each stroke mechanism 1. The sprayed workpiece in the tower crane is set in the middle position of the four spraying devices, and the sprayed workpiece is controlled to be lifted and moved by a lifting mechanism. In implementation, the lifting mechanism can be designed to include a hook 18, a hook structure 17, a carbon steel hanger 16, and a conveying chain 19, etc. The entire lifting mechanism is installed and connected to the top position of the tower crane. The set conveying chain 19 is connected to the carbon steel hanger 16, the other end of the carbon steel hanger 16 is connected to the hook structure 17, and several hooks 18 for lifting the sprayed workpiece are installed and connected to the hook structure 17. In this way, the sprayed workpiece is lifted and limited by the hook 18, and then the set control system controls the conveying chain 19 to start through existing technologies, drives the carbon steel hanger 16 and the hook structure 17 to move, and further drives the hook 18 on the hook structure 17 to lift and limit the sprayed workpiece to move up and down. Then, the system controls the activities of each spraying device to drive the spray gun device 5 to spray the sprayed workpiece. In implementation, the set conveying chain is not limited to structural devices such as heavy-duty chains, accumulation chains, friction chains, and transport trolleys.

[0028] Furthermore, during the implementation process of controlling the activities of each spraying device through this system, taking the control of one of them as an example:

[0029] The designed system controls the stroke mechanism 1 to drive the overall position of the spray gun device 5 installed and connected to the spraying device, that is, to move up and down and left and right generally, so as to move the spray gun device 5 to an approximate position to spray the entire sprayed workpiece. At this time, in order to spray some positions that have not been sprayed locally, the first servo motor 7 set by the designed system needs to be started at this time. The first servo motor 7 drives the rotating shaft 15 through the shaft coupling 8 to rotate around the support connecting shaft 2 through a ball hinge structure (that is, one end of the set ball head seat 9 is movably connected to the end of the support connecting shaft 2 close to the ball head seat 9 through the ball head, and the other end of the ball head seat 9 is movably connected to the rotating shaft 15 through the ball head), so that the rotating shaft 15 drives the spray gun device 5 installed and connected through the extension mechanism to spray the locally unsprayed position of the sprayed workpiece lifted by the hoisting mechanism installed on the tower crane. In order to further achieve full spraying, the designed second servo motor 10 is started by the designed system. The second servo motor 10 drives the lead screw 12 installed in the sliding groove opened on the walking guide beam 3 to rotate through gear meshing. The rotation of the lead screw 12 drives the sliding connection seats to slide along the sliding groove opened on the walking guide beam 3 respectively. Thus, the movement of the sliding connection seats drives the movement of the spray gun devices 5 respectively connected to the sliding connection seats through the connecting rods 13, so as to drive the spray gun device 5 connected to the cross bar 4 through the connecting rod 13 and installed on the cross bar 4 to perform telescopic translation; and cooperate with the hydraulic rod 11 to expand and contract to drive the walking guide beam 3 connected through the hinge seat to "swing" to an appropriate angular position, so as to further spray the unsprayed local positions at different positions of the sprayed workpiece.

[0030] In terms of the overall design, this spraying device is used to make up for the positions that have not been sprayed on the sprayed workpiece during the spraying process of the tower crane, replace manual operation, reduce the number of workers and workload, improve efficiency and save costs.

However, the present invention is not limited to the specific details in the above-described embodiments in the specification. Within the technical concept scope of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.
