Description

Technical Field

[0001] This utility model relates to the field of scaffolding pipe technology, and in particular to a rapid paint repair device for scaffolding pipes. Background Technology

[0002] Scaffolding pipes, a common auxiliary material in petrochemical construction, are indispensable for high-altitude construction. Most scaffolding pipes are made of carbon steel and are prone to impacts and friction during use and transportation, requiring frequent anti-corrosion maintenance. Painting is the most common and economical way to protect them. Traditional touch-up painting involves placing the pipes on supports and then manually painting the areas needing repair. This method is not only labor-intensive and inefficient, but also produces a strong paint odor that pollutes the environment. Utility Model Content

[0003] To address the inconvenience of painting scaffolding pipes, this invention proposes a rapid painting device for scaffolding pipes, which uses mechanical equipment to replace manual painting while reducing the spread of paint odor.

[0004] The technical solution adopted in this utility model is to design a quick paint repair device for scaffolding pipes, including a support device for supporting the pipe body and a paint coating device for applying paint to the surface of the pipe body. The support device includes a first clamping assembly and a second clamping assembly arranged opposite to each other. The second clamping assembly includes a second clamping part for fixing the end of the pipe body and a second fixing seat for rotating and supporting the second clamping part. The first clamping assembly includes a first clamping part for fixing the other end of the pipe body, a first motor for controlling the rotation of the first clamping part, and a telescopic device for controlling the extension and retraction of the first clamping part relative to the second clamping part. The paint coating device includes a first moving cavity and a moving device for controlling the first moving cavity to move along the length direction of the pipe body. The first moving cavity is provided with a through hole for the pipe body to pass through, and a paint brush that extends and retracts radially relative to the pipe body is provided in the first moving cavity.

[0005] In some embodiments, a second movable cavity that moves along the length of the tube is provided, the second movable cavity having a through hole through which the tube passes, and a cleaning brush that extends and retracts radially relative to the tube is provided inside the second movable cavity.

[0006] In some embodiments, the bottom of the second moving cavity is conical, and the bottom of the second moving cavity is connected to the dust collection trough.

[0007] In some embodiments, the edge of the through hole is provided with a flexible lip.

[0008] In some embodiments, the first moving cavity and the second moving cavity have the same length. Both the second clamping part and the first clamping part include a clamping head that presses against the end of the tube body and a connecting rod that connects to the clamping head. The length of the connecting rod is greater than the length of the first moving cavity, and the radial dimension of the connecting rod is smaller than the through hole.

[0009] In some embodiments, an image acquisition device that moves along the length of the tube is also included. The first moving cavity, the second moving cavity, and the image acquisition device are slidably disposed on a guide rail parallel to the tube. The image acquisition device is disposed between the first moving cavity and the second moving cavity. The length of the connecting rod is greater than the sum of the length of the image acquisition device and the length of the first moving cavity.

[0010] In some embodiments, a liquid collection tank is provided at the bottom of the first movable cavity.

[0011] In some embodiments, an exhaust device is connected above the first movable cavity.

[0021] The following are specific embodiments of this utility model, and the technical solution of this utility model will be further described with reference to the accompanying drawings. However, this utility model is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of features described in the embodiments are not necessarily necessary for the solution of the utility model.

[0022] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0023] like Figure 1 , 2 As shown in Figure 3, a quick paint repair device for scaffolding pipes includes a support device for supporting the pipe body 1 of the scaffolding pipe, and a paint coating device for applying paint to the surface of the pipe body 1. The support device includes a first clamping assembly and a second clamping assembly arranged opposite to each other on the axis of the pipe body 1.

[0024] The second clamping assembly includes a second clamping part for fixing the end of the tube body 1 and a second fixing seat 2 for rotating the second clamping part, thereby allowing the second clamping part to rotate freely.

[0025] The first clamping assembly includes a first clamping part for fixing the other end of the tube body 1, a first motor 5 for controlling the rotation of the first clamping part, and a telescopic device 6 for controlling the extension and retraction of the first clamping part relative to the second clamping part. The telescopic device 6 can be, for example, a cylinder, an electric cylinder, or other telescopic mechanism.

[0026] Specifically, both the second clamping part and the first clamping part include a clamping head 3 that presses against the end of the tube body 1 and a connecting rod 4 that connects the clamping head 3. The clamping head 3 is a cone, and the tip of the cone can be inserted into the end of the tube body 1 to prevent the tube body 1 from moving axially and radially. The second fixing seat 2 is a bearing seat, so that the connecting rod 4 can rotate freely.

[0027] When touching up the paint, the tube body 1 needs to be fixed to the support device first. At this time, as long as the telescopic device 6 extends and retracts so that the first clamping part is away from the second clamping part, so that the distance between the two is greater than the length of the tube body 1, so that the two ends of the tube body 1 correspond to the clamping head 3, then the device extends and retracts so that the first clamping part is close to the second clamping part, so that the tube body 1 is clamped between the two clamping heads 3. At this time, the motor can rotate to drive the tube body 1 to rotate around its own axis.

[0028] The painting device includes a first moving cavity 7 and a moving device for controlling the first moving cavity 7 to move along the length direction of the tube 1. The first moving cavity 7 is provided with a through hole 14 for the tube 1 to pass through, so that the first moving cavity 7 can move along the tube 1. A painting brush that can extend and retract radially relative to the tube 1 is provided in the first moving cavity 7. In this embodiment, the painting brush is connected to the first moving cavity 7 through a first cylinder 8. The extension and retraction of the first cylinder 8 controls the painting brush to approach or move away from the tube 1.

[0029] When touch-up painting is needed, the moving device moves the first moving cavity 7, thereby moving the paintbrush to the position where touch-up painting is needed. The paintbrush extends and contacts the tube 1, thereby applying paint to the tube 1. In this embodiment, the paintbrush is a roller brush 9 located above the tube 1. A liquid storage tank 10 is provided above the roller brush 9. The bottom of the liquid storage tank 10 is provided with mesh holes corresponding to the roller brush 9. The liquid storage tank 10 is connected to a liquid supply device, which is used to deliver paint liquid to the liquid storage tank 10. Then, the paint enters the roller brush 9 through the mesh holes. The liquid supply device can be, for example, a liquid supply pump connected to the paint tank. The roller brush 9 is controlled to rotate by a second motor 11, thereby applying paint to the surface of the tube 1.

[0030] The bottom of the first movable cavity 7 is also provided with a liquid collection tank 12 to collect the fallen paint liquid.

[0031] The first movable cavity 7 is connected to the exhaust device 13 above, so as to remove the air polluted by paint in a timely manner. The extracted gas can be purified by adsorption agents such as activated carbon.

[0032] It also includes a second moving cavity 20 that moves along the length of the tube 1. The second moving cavity 20 is also provided with a through hole 14 for the tube 1 to pass through. A cleaning brush 21 that can extend and retract radially relative to the tube 1 is provided in the second moving cavity 20 to clean the paint-touching area before touch-up painting. The distance of the cleaning brush 21 relative to the tube 1 is controlled by a second cylinder 19, thereby controlling the cleaning brush 21 to approach or move away from the tube 1. The cleaning brush 21 can be an ultrasonic vibration cleaning brush 21 or an electric brush head whose brush head is controlled by a motor to rotate, etc.

[0033] The bottom of the second moving cavity 20 is conical, and the edge of the through hole 14 is also provided with a flexible lip 15, so that the through hole 14 and the tube body 1 are better sealed, avoiding dust pollution of the air during cleaning. The bottom of the second moving cavity 20 is connected to the dust collection groove 16 so as to collect the dust during cleaning.

[0034] The first moving cavity 7 and the second moving cavity 20 have the same length. The length of the connecting rod 4 is greater than the length of the first moving cavity 7. The radial dimension of the connecting rod 4 is smaller than the through hole 14, so that both the first moving cavity 7 and the second moving cavity 20 can move onto the connecting rod 4 and thus leave the tube body 1, which facilitates the disassembly of the tube body 1 and avoids mutual interference between the cleaning and repainting of the tube body 1.

[0035] It also includes an image acquisition device 17, such as a vision camera, that moves along the length of the tube 1 to determine the location that needs to be repainted by image recognition. The first moving cavity 7, the second moving cavity 20, and the image acquisition device 17 are slidably arranged on a guide rail 18 parallel to the tube 1. The image acquisition device 17 is arranged between the first moving cavity 7 and the second moving cavity 20. The length of the connecting rod 4 is greater than the sum of the length of the image acquisition device 17 and the length of the first moving cavity 7 to avoid the image acquisition device 17 affecting the movement of the first moving cavity 7 or the second moving cavity 20 relative to the tube 1.

[0036] The tube body 1 is horizontally arranged, and the image acquisition device 17, the first moving cavity 7 and the second moving cavity 20 are slidably suspended on the guide rail 18. The image acquisition device 17, the first moving cavity 7 and the second moving cavity 20 can be controlled by a linear motor, belt drive mechanism and other transverse movement devices to move along the guide rail 18.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0038] Although this document uses a number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention. The order of actions, steps, etc., in the apparatus and methods shown in the specification and drawings can be implemented in any order unless a specific order is explicitly specified, and as long as the output of a preceding process is not used in a subsequent process. Similar sequential terms used for descriptive convenience (e.g., "firstly," "next," "secondly," "again," "then," etc.) do not imply that the actions must be performed in such an order.

[0039] Those skilled in the art will understand that all directional references (e.g., above, below, up, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not imply (e.g., a limitation on the scope of the invention as defined by the appended claims) a limitation on the scope of the invention as defined by the appended claims. They are merely for the purpose of facilitating the description of the application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation. The directional terms "inside" and "outside" refer to inside or outside relative to the outline of the respective components themselves.

[0040] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0041] Additionally, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or minor deviations in conditions, quantities, values, or dimensions, some of which are within manufacturing tolerances or limits. It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components; unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
