Description

Technical Field

[0001] This utility model relates to a device for cleaning the surface of bent pipes. Background Technology

[0002] Pipe bending is performed using a complete set of bending equipment, and there are two processes: cold bending and hot bending.

One end of the connecting rod 32 is slidably mounted on the gantry frame along the sliding direction of the support 21, and the other end of the connecting rod 32 extends toward the base 1. The cleaning cylinder 33 is rotatably mounted on the end of the connecting rod 32 facing the base 1. The inner wall of the cleaning cylinder 33 is provided with a plurality of sandblasting heads 4 evenly distributed around the axis of the cleaning cylinder 33. Each sandblasting head 4 is connected to an external sandblasting machine. The surface of the bent pipe is sandblasted and cleaned by the sandblasting heads 4. The sandblasting removes rust and dirt from the surface of the bent pipe and extends the service life of the bent pipe.

[0021] The sliding gantry frame 31 includes two support columns 311 and a crossbeam 312. The two support columns 311 are symmetrically arranged on the base 1. The base 1 is provided with cleaning grooves 11 corresponding to the two support columns 311. One end of each support column 311 is fixedly provided with a cleaning slider 5 that can slide with the cleaning groove 11. Each support column 311 is fixedly provided with an extension block 3111.

The ball bearing 82 is rotatably disposed in the circular groove. The cleaning cylinder 33 moves along the extension direction of the bend under the guidance formed by the contact between the ball bearing 82 and the outer surface of the bend. The ball bearing 82 makes the cleaning cylinder 33 move more smoothly on the bend. At the same time, when the cleaning cylinder 33 changes direction at the bend of the bend, it is guided by the ball bearing 82, thus changing direction more stably.

[0023] There are two guide components, which are respectively located on both sides of the sandblasting head 4 and are located near the two ends of the cleaning cylinder 33.

[0024] The support portion 21 includes a first fixed half-ring 211 and a second fixed plate ring 212, both of which are slidably disposed on the base 1. The first fixed half-ring 211 and the second fixed plate ring 212 can be slidably attached to the side wall of the end of the bend after sliding. The base 1 is provided with a support groove 12, in which a first support slider 121 and a second support slider 122 are slidably disposed. One end of the first fixed half-ring 211 is fixedly disposed on the first support slider 121, and one end of the second fixed half-ring is fixedly disposed on the second support slider 122. Two support driving devices 22 are provided, corresponding to the first fixed half-ring 211 and the second fixed plate ring. The driving ends of the two support driving devices 22 are fixedly connected to the first support slider 121 and the second support slider 122, respectively. The first fixed half-ring 211 and the second fixed plate ring are slidably disposed on the base 1 through the sliding cooperation of the first support slider 121 and the second support slider 122 with the support groove 12 and the driving of the support driving devices 22.

[0025] A rubber layer 9 for increasing friction with the bend is fixed on the inner ring wall of the first fixed half ring 211 and the second fixed plate ring 212.

[0026] The aforementioned support groove 12 extends perpendicularly to the extension direction of the cleaning groove 11. Both the support groove 12 and the cleaning groove 11 have slots extending in the extension direction of the corresponding groove on their inner walls. Both the support slider and the cleaning slider 5 are fixedly provided with blocks that can slide with the slots. The support slider and the cleaning slider 5 are restricted within the corresponding support groove 12 and the cleaning groove 11 by the sliding cooperation between the blocks and the slots.

[0027] The working principle of this utility model is as follows: The two ends of the bent pipe to be cleaned are placed at the support assembly 2, and the middle part of the bent pipe passes through the cleaning assembly 3; the first fixed half ring 211 and the second fixed plate ring 212 in the support assembly 2 at both ends of the bent pipe slide within the support groove 12 through the driving of the first support slider 121 and the second support slider 122 by the two support driving devices 22, and the first fixed half ring 211 and the second fixed plate fixedly support the two ends of the bent pipe after sliding; the middle part of the bent pipe passes through the cleaning cylinder 33, and the middle part of the bent pipe contacts the ball bearing 82 on the base 81 and can slide with the cleaning cylinder 33 under the action of the ball bearing 82;

[0028] The cleaning gantry is driven by a sliding drive device to rotate the screw 6. The rotating screw 6 forms a threaded engagement with the screw hole, causing the cleaning gantry to slide within the cleaning groove 11. The sliding cleaning gantry moves between the two support components 2 during cleaning. At the same time, when the cleaning cylinder 33 is at the bend of the pipe, it rotates adaptively under the connection of the connecting rod 32 through the ball connector 7. When the cleaning cylinder 33 needs to change the cleaning direction, the connecting drive device 3112 drives the connecting slider 321 to slide within the connecting groove. The connecting slider 321 drives the connecting rod 32 to move the cleaning cylinder 33 along the extension direction of the support groove 12. Thus, after passing the bend of the pipe, the cleaning cylinder 33 slides along the extension direction of the bend.

[0029] As the cleaning cylinder 33 slides on the bend, each of the sandblasting heads 4 inside the cleaning cylinder 33 simultaneously performs sandblasting cleaning on the surface of the bend.

[0030] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
