DETAILED DESCRIPTION

[0022] The following is a specific embodiment of the present application, and the technical solutions of the present application are further described in conjunction with the drawings, but the present application is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required by the solutions of the invention.

[0023] The principles and structures of the present application are described in detail below in conjunction with the drawings and embodiments. EMBODIMENT

[0024] As Figure 1 , 2 , 3, 4, a scaffold pipe paint supplementing device, comprising a positioning frame for clamping a pipe body and a paint device for painting the surface of the pipe body.

[0025] The positioning frame comprises a rotating disc 1, a plurality of through holes are distributed circumferentially on the rotating disc, a positioning sleeve 2 is connected to rotate in the through hole, and a limiting stop body is arranged on the positioning sleeve to be clamped on both sides of the first sliding groove, so that the positioning sleeve can rotate relative to the through hole around its own rotating shaft and cannot move relative to the axis.

[0026] The telescopic rod 3 is slidably arranged in the positioning sleeve, and the telescopic rod can be telescoped relative to the positioning sleeve in the axial direction.

[0027] The first end of the telescopic rod and the end of the positioning sleeve are provided with a chuck for fixing the end of the pipe body, the telescopic rod is telescopic relative to the positioning sleeve so that the chuck clamps or releases the pipe body, in particular, the chuck comprises a first connecting rod 4 distributed circumferentially on the end of the positioning sleeve and a second connecting rod 5 distributed circumferentially on the end of the telescopic rod, one end of the first connecting rod is rotationally connected with the positioning sleeve and the other end is rotationally connected with the end of the second connecting rod, the other end of the second connecting rod is rotationally connected with the telescopic rod, each telescopic rod is controlled to rotate by a first motor 6, the telescopic rod is controlled to be telescopic relative to the turntable by a telescopic mechanism, which can be a telescopic control device such as an air cylinder or an electric cylinder.

[0028] When the telescopic rod moves relative to the positioning sleeve, the connection between the first connecting rod and the second connecting rod becomes larger or smaller in the radial direction, that is, the chuck expands or shrinks in the radial direction. When the pipe body needs to be fixed, the telescopic rod is first extended relative to the positioning sleeve towards the pipe body, so that the chuck shrinks, then the end of the pipe body is sleeved on the chuck, then the telescopic rod is retracted relative to the positioning sleeve, so that the chuck expands, so that the connection between the first connecting rod and the second connecting rod presses on the inner cavity wall of the pipe body, and the chuck is fixedly connected relative to the pipe body under the action of friction, so that the first motor can drive the pipe body 7 to rotate.

[0029] The paint coating device comprises a track 8 arranged in parallel with the length direction of the pipe body and a paint coating brush 9 moving along the track, so that the paint coating brush moves to the position needing to be painted, and the paint coating brush contacts the pipe body when the pipe body rotates to achieve painting of the position needing to be painted. The paint coating brush can be supplied with paint by an automatic paint supply device, and the paint coating brush can be controlled to move along the track by a linear motor, a conveyor belt or other transmission mechanism. A visual camera 10 for detecting the surface of the pipe body can also be arranged on the track and can move along the track, so that the position needing to be painted of the pipe body is quickly detected by image recognition, so that the paint coating brush moves to the position corresponding to the position in the radial direction, and then moves to the position of the paint coating brush by cooperation of the rotation of the pipe body and the revolution to achieve painting.

[0030] The turntable is controlled to rotate by a second motor 11, so as to control all the pipe bodies to revolve around the axis of the turntable, the first motor controls the rotation speed of each pipe body around its own rotation axis, and the revolution and the rotation are cooperated to adjust the rotation speed of the pipe body relative to the paint coating brush, so as to control the area of painting.

[0031] The through hole is a first sliding slot 12 with a length in the radial direction of the rotating disc, and a radial moving device is arranged between the telescopic rod and the second motor, which controls the movement of the telescopic rod in the radial direction of the rotating disc. Specifically, the radial moving device of the embodiment includes a positioning disc 13 coaxial with the rotating disc, and a radial second sliding slot 14 is arranged on the positioning disc, through which the telescopic rod slides. The second sliding slot intersects the first sliding slot with respect to the telescopic rod. An angle adjusting mechanism is arranged between the rotating disc and the positioning disc, which controls the relative rotation angle of the rotating disc and the positioning disc about the axis, i.e. the first sliding slot has a certain included angle with the radial direction of the rotating disc, while the length direction of the second sliding slot is along the radial direction of the positioning disc. Therefore, the first sliding slot and the second sliding slot intersect in the circumferential direction as viewed from the axis of the rotating disc. In this way, the telescopic rod is limited in the intersection of the first sliding slot and the second sliding slot and cannot move radially and circumferentially. The angle adjusting mechanism can be, for example, a motor or other device that can control the rotation of the rotating disc relative to the positioning disc. When the rotating disc rotates relative to the positioning disc, the intersection position of the first sliding slot and the second sliding slot can be changed, and in turn the radial position of the telescopic rod can be changed. In this way, the radial position of the pipe body can be changed, so that when the pipe body of different diameters is clamped, the position of the telescopic rod can be adjusted to enable the surface of the pipe body to always be in contact with the paint brush.

[0032] A limiting block is arranged on the telescopic rod and clamped on both sides of the second sliding slot, which prevents the telescopic rod from moving axially relative to the positioning disc, so that the telescopic rod can be moved by the positioning disc. A telescopic mechanism is connected between the rotating disc and the positioning disc, which controls the distance between the rotating disc and the positioning disc, thereby controlling the clamping or loosening of the pipe body by the chuck.

[0033] A positioning rod 15 is further arranged radially relative to the positioning disc, and the first motor is arranged radially on the positioning rod, so that the first motor can move along the second sliding slot in the radial direction of the positioning disc and cannot rotate relative to the positioning rod, so as to control the rotation of the telescopic rod relative to the positioning sleeve and control the rotation speed of the pipe body.

[0034] The telescopic mechanism is a telescopic cylinder 16, such as a controllable telescopic device of a gas cylinder or an electric cylinder. The positioning disc and the positioning rod are fixedly connected to the cylinder body of the telescopic cylinder, and the piston of the telescopic cylinder is connected to the rotating disc, thereby adjusting the axial distance between the rotating disc and the positioning disc, and in turn adjusting the distance between the end of the shaft sleeve and the telescopic rod, so as to adjust the expansion or contraction of the chuck, thereby clamping or releasing the end of the pipe body.

[0035] The rotation shaft of the second motor is connected to the cylinder of the telescopic cylinder, so as to control the rotation of the positioning disc together with the rotating disc, and then control the rotation of all the pipe bodies around the rotation shaft of the positioning disc, and the rotation of the pipe bodies around the rotation shaft of the positioning disc is equivalent to revolution, and the first motor controls the rotation of the pipe bodies around their own rotation shafts, which is equivalent to revolution, and through the cooperation of the revolution and the revolution speed, the pipe bodies are rotated to the position of the paint brush, so that the position needing paint is matched with the brush head of the paint brush, so as to paint at the position, and the rotation speed of the pipe bodies relative to the paint brush can also be controlled, so as to control the painting area of the paint.

[0036] The positioning frames are oppositely arranged, so that both ends of the pipe body can be fixed by the positioning frames, so that the pipe body is clamped in a horizontal state, and at least one of the positioning frames is controlled to move in the length direction of the pipe body by a moving mechanism 17, such as a cylinder, so as to adjust the distance between the two positioning frames, when the pipe body needs to be clamped, the two positioning frames are moved away, so that the pipe body is located between the two clamping heads of the positioning frames, then the two positioning frames are moved close to each other, so that the two clamping heads are inserted into the two ends of the pipe body, and then the clamping heads are controlled to expand to clamp and fix the two ends of the pipe body, when the pipe body with finished paint needs to be removed, the clamping heads are loosened, and then the positioning frames are moved away, so that the pipe body can be removed.

[0037] A plurality of parallel tracks can be arranged circumferentially on the positioning frame, and the paint brush is arranged on each track, so as to simultaneously paint a plurality of pipe bodies, and a telescopic device 19 can be arranged between the paint brush and the track, and the telescopic device controls the distance between the paint brush and the pipe body.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
