Description

Technical Field

[0001] The utility model relates to the technical field of grinding surfaces for cleaning purposes, in particular to a column surface cleaning device. Background Art

[0002] Existing cleaning devices for removing rust and dust from valve screws typically require the screw to be removed and then inserted into one end of the cleaning device. The screw itself rotates, or the screw rotates within the cleaning device, creating friction between the screw and the cleaning tool in the cleaning device, thereby cleaning the screw. For valves in use on-site, manual cleaning with cotton yarn or sandpaper is often used to clean the screw without removing it. This is labor-intensive and has poor cleaning results. In addition to screws, other cylindrical components also require surface cleaning.

[0003] In the existing surface cleaning devices for columnar parts, a Chinese utility model patent with authorization announcement number CN203330896U and authorization announcement date of 2013.12.11 discloses a grinding belt. The grinding belt (i.e., the column surface cleaning device) consists of a handle, a connecting buckle, a main body and a steel wire. The steel wire is fixed to the main body of the grinding belt. Handles are fixed at both ends of the main body, and the handles are respectively fixed to the connecting buckles. When in use, the grinding belt is half-wrapped around the surface of the pipeline (i.e., the columnar part), the connecting buckle is manually held, and the two connecting buckles are pulled in a cycle, so that the steel wire continuously rubs the surface of the pipeline, thereby achieving cleaning of the pipeline surface.

[0004] However, the above-mentioned grinding belt can only be half-wrapped around the surface of the cylinder when in use. When the grinding belt moves from one end of the cylinder to the other end along the length of the cylinder, it can only clean half of the area of the cylinder surface. The grinding belt needs to be half-wrapped around the other half of the cylinder surface again and ground and cleaned again, resulting in low cleaning efficiency of the cylinder. Utility Model Content

Both ends of the grinding belt are provided with detachable connection structures for maintaining the shape of the grinding cylinder. The driving belt is used to be wrapped around the outside of the grinding cylinder and frictionally cooperate with the outer peripheral surface of the grinding cylinder to drive the grinding cylinder to rotate through its own movement.

[0008] The beneficial effect of the above technical solution is that: the utility model is a pioneering invention, the cylindrical surface cleaning device includes a grinding belt and a driving belt, the side of the grinding belt is provided with a grinding layer for grinding the cylindrical surface, the grinding belt is used to wrap around the outside of the cylindrical body to form a grinding cylinder, and the two ends of the grinding belt are provided with detachable connection structures for maintaining the shape of the grinding cylinder, the driving belt is wrapped around the outside of the grinding cylinder and frictionally cooperates with the outer circumference of the grinding cylinder, and when the driving belt moves, the grinding cylinder can be rotated by friction. When in use, the grinding belt can pass around from one side of the cylindrical body and be wrapped around the cylindrical surface through the detachable connection structures at both ends to form a grinding cylinder, at this time, the grinding layer contacts the cylindrical surface and fully surrounds the cylindrical surface, so that when the driving belt drives the grinding cylinder to move around the cylindrical surface, the grinding layer can rotate around the cylindrical surface, and when the grinding layer moves from one end of the cylindrical body along the length direction of the cylindrical body to the other end of the cylindrical body, the cylindrical surface can be cleaned, effectively improving the cleaning efficiency.

[0009] Furthermore, the column surface cleaning device also includes a driving mechanism, which includes a driving cylinder, a rotating shaft extending from both ends of the driving cylinder, a supporting structure supporting the rotation of the rotating shafts at both ends, and a control structure for controlling the rotation of the rotating shaft.

[0014] Furthermore, the support structure also includes side plates connected between the edges of the two support plates and the edge of the connecting plate. There are two side plates so that the support structure forms a box structure with only one side open, and the opening is for the driving belt to pass through.

[0023] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0024] In response to the technical problems existing in the prior art, the basic technical concept of the present invention is as follows: a cylindrical surface cleaning device includes a grinding belt and a drive belt, a grinding layer for grinding the cylindrical surface is provided on the side of the grinding belt, the grinding belt is used to wrap around the outside of the cylindrical body to form a grinding tube, and the two ends of the grinding belt are provided with detachable connection structures for maintaining the shape of the grinding tube. During use, the grinding belt can pass around from one side of the cylindrical body and wrap around the cylindrical surface through the detachable connection structures at both ends to form a grinding tube, at which time the grinding layer contacts the cylindrical surface. The drive belt is used to wrap around the outside of the grinding tube and frictionally engage with the outer circumference of the grinding tube, so that when the driving belt drives the grinding tube to rotate around the cylindrical body, the grinding layer can rotate around the cylindrical surface. Therefore, the cylindrical surface can be cleaned by simply moving the grinding tube from one end of the cylindrical body to the other end along the length of the cylindrical body, effectively improving the cleaning efficiency.

[0025] The embodiment of the cylinder surface cleaning device in the utility model:

[0026] In this embodiment, the cylinder to be cleaned is the valve screw. Figure 1 and Figure 2 As shown, the cylindrical surface cleaning device includes a grinding belt 2 and a driving belt 3. In this embodiment, the cylindrical surface cleaning device also includes a driving mechanism 1. The grinding belt 2 can be wrapped around the valve screw to form a grinding cylinder. The driving belt 3 can be wrapped around the outside of the grinding cylinder and frictionally engage with the outer circumference of the grinding cylinder. The driving belt 3 can drive the grinding cylinder to rotate on the surface of the valve screw through its own movement. The driving mechanism 1 can provide power for the movement of the driving belt 3.

[0027] like Figure 3 As shown, the grinding belt 2 includes a rubber 21. The rubber 21 can frictionally cooperate with the drive belt 3, so that when the drive belt 3 moves, the grinding belt 2 rotates around the surface of the valve screw under the action of friction. A metal skin 22 is fixedly provided on one side of the rubber 21. When the grinding belt 2 is wrapped around the surface of the valve screw, the metal skin 22 can provide support, so that the grinding belt 2 is not easily deformed during rotation. A grinding layer 23 is fixed on the other side of the metal skin 22. The grinding layer 23 is used to grind the surface of the valve screw to achieve cleaning of the valve screw surface. In this embodiment, the grinding layer 23 includes a rubber fixed to the metal skin 22 and cotton yarn or steel wire fixed on the other side of the rubber for grinding and cleaning the surface of the valve screw. The rubber 21, the metal skin 22 and the grinding layer 23 together constitute the grinding belt 2.

[0028] The polishing belt 2 can be wrapped around the outside of the valve screw to form a polishing cylinder. Both ends of the polishing belt 2 are provided with a detachable connecting structure for maintaining the shape of the polishing cylinder. In this embodiment, the detachable connecting structure is set as Velcro, which are a first male Velcro 24 and a first female Velcro 25, respectively. The first male Velcro 24 is fixed at the end of the rubber 21, and the first female Velcro is fixed at the end of the polishing layer 23, and the first male Velcro 24 and the first female Velcro 25 are respectively located at different ends of the polishing belt 2. During use, the polishing tape 2 can be passed around the valve screw from one side and wrapped around the valve screw surface, so that the polishing layer 23 contacts and closely adheres to the valve screw surface. The first male Velcro 24 and the first female Velcro 25 are affixed together, so that the polishing tape 2 forms a polishing cylinder. When the polishing cylinder rotates around the valve screw surface, the polishing layer 23 can also rotate around the valve screw surface. Therefore, when cleaning the valve screw surface, the polishing cylinder only needs to be moved along the valve screw surface along the length of the valve screw to achieve cleaning efficiency. At the same time, the first male Velcro 24 and the first female Velcro 25 can be reused, effectively reducing the cost of use.

[0029] like Figure 1 and Figure 2As shown, the drive mechanism 1 includes a drive cylinder 14, a rotating shaft 13 extending from both ends of the drive cylinder 14, a support structure for supporting the rotation of the rotating shaft 13 at both ends, and a control structure for controlling the rotation of the rotating shaft 13. The support structure includes two parallel support plates 151 arranged at intervals and a connecting plate 152 connected between the two support plates 151. The two support plates 151 and the connecting plate 152 form a U-shaped structure. The drive cylinder 14 is located between the two support plates 152. The rotating shafts 13 at both ends of the drive cylinder 14 respectively pass through the two support plates 151. The two support plates 151 are respectively provided with bearings 16 for supporting the rotation of the rotating shaft 13. In this embodiment, the support structure also includes two side plates 153 connected between the edges of the two support plates 151 and the edges of the connecting plate 152. The support plates 151, the connecting plate 152, and the side plates 153 together form a box 15 with only one side open.

[0030] like Figure 1 As shown, the support structure also includes a force-applying frame 18 for a person to hold in order to apply tension to the support structure. The force-applying frame 18 is U-shaped and includes two parallel and spaced connecting arms 181 and a force-applying arm 182 connected between the two connecting arms 181. The force-applying arm 182 can be held by a person. The two connecting arms 181 are respectively fixedly connected to the two support plates 151. In this embodiment, the ends of the two connecting arms 181 are respectively fixedly connected to the two support plates 151 by a plurality of screws 17. Specifically, two screws 17 are provided on each connecting arm 181.

[0031] like Figure 1 and Figure 2 As shown, the control structure includes a handwheel 12 that is transmission-connected to a rotating shaft 13. A crank 11 is provided on the handwheel 12. When in use, the crank 11 can be held and the handwheel 12 can be rotated to provide driving force for the driving mechanism 1. The handwheel 12 can drive the rotating shaft 13 to rotate, and the rotating shaft 13 drives the driving cylinder 14 to rotate.

[0032] like Figure 1 ,and Figure 2 and Figure 4 As shown, the drive belt 3 is designed to wrap around the outside of the drive cylinder 14 and, together with the polishing cylinder, form a belt drive structure. In this embodiment, the drive belt 3 can be connected to form an endless belt that wraps around the outside of the polishing cylinder and the drive cylinder 14. The drive belt 3 passes through the opening of the support structure, wrapping around the outside of the drive cylinder 14 and passing through the support structure. At the same time, each end of the drive belt 3 is provided with a detachable connection structure. In this embodiment, the detachable connection structure is configured as a second male hook and loop fastener, 31, and a second female hook and loop fastener, 32, respectively. The second male hook and loop fastener 31 and the second female hook and loop fastener 32 are located on different sides of the drive belt 3. The drive belt 3 is semi-circular around the outside of the drive cylinder 14 and passes through the open side of the support structure.

[0033] During use: Wrap the polishing tape 2 around the surface of the end of the valve screw to be cleaned, and then glue the first male Velcro 24 and the first female Velcro 25 together, so that the polishing tape 2 is wrapped around the surface of the valve screw part to form a polishing cylinder; when using it for the first time, wrap the driving belt 3 around the outside of the driving cylinder 14, and pass the two ends of the driving belt 3 out of the open side of the self-supporting structure. After the first use, the driving belt 3 does not need to be disassembled to reduce the subsequent use process and improve efficiency; wrap the driving belt 3 around the outside of the polishing cylinder, and glue the second male Velcro 31 and the second female Velcro 32 at the two ends of the driving belt 3 together to form a ring-shaped belt; the user can hold the force arm 182 with one hand, lift the box body 15, and drive The belt 3 is tightened, and the other hand holds and turns the crank 11, thereby driving the handwheel 12 to rotate, and then the rotating shaft 13, the driving cylinder 14, and the driving belt 3 are rotated in turn. The driving belt 3 drives the grinding cylinder to rotate around the surface of the valve screw through the friction force, so that the grinding layer 23 on the inside of the grinding cylinder rotates on the surface of the valve screw and grinds and cleans the surface of the valve screw; pull the force arm 182 horizontally to make it move slowly along the length direction of the valve screw part, thereby driving the box body 15 to move, and the box body 15 drives the driving belt 3 to move, and then the grinding cylinder moves horizontally on the surface of the valve screw with the driving belt 3 under the action of friction until the grinding cylinder moves from one end of the valve screw part to the other end, and the cleaning is completed.
