Description

Technical Field

[0001] The utility model relates to the technical field of expansion joint processing, in particular to an inner hole cleaning device for expansion joint processing. Background Art

[0002] The compensator is also called an expansion joint or telescopic joint. It is composed of a bellows and end pipes, brackets, flanges, conduits and other accessories that constitute its working body. It is a compensating element. The compensator uses the effective expansion and contraction of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate for the axial, lateral and angular displacements of pipelines, conduits, containers, etc. When processing the expansion joint, it is necessary to spray an anti-corrosion layer on the expansion joint for corrosion protection. Before spraying the anti-corrosion layer, the inner and outer walls of the expansion joint need to be cleaned.

[0003] However, when cleaning the expansion joint, the inner and outer walls of the expansion joint need to be cleaned separately, resulting in poor cleaning efficiency and affecting subsequent processing effects. Therefore, this method can be improved. Utility Model Content

[0028] Reference Figure 1-3 The utility model provides an inner hole cleaning device for expansion joint processing, comprising:

[0029] Cleaning unit 100 and auxiliary unit 200;

[0030] The cleaning unit includes a base 101, a hydraulic cylinder is fixedly installed on the top of the base 101, a partition 103 is fixedly installed on the top of the hydraulic cylinder 102, a transverse movement component 104 is provided on the top of the partition 103, an electric telescopic rod 105 is fixedly installed on the top of the base 101, a first motor 106 is fixedly installed on one side of the electric telescopic rod 105, a fixed roller 107 is fixedly installed on the output shaft of the first motor 106, an expansion joint 108 is slidably sleeved on the outer wall of the fixed roller 107, one end of the expansion joint 108 is fixedly installed with a flange, a transmission ring 109 that matches the flange is fixedly installed on the outer wall of the output shaft of the first motor 106, a plurality of cylindrical blocks are fixedly installed on one side of the transmission ring 109, and the expansion joint 108 can be driven to rotate through the transmission ring 109 by inserting the cylindrical blocks into the threaded holes of the flange;

[0031] The auxiliary unit 200 includes a round rod 201, which is fixedly installed on one side of the electric telescopic rod 105. A concave ring 203 is fixedly installed on the outer wall of the round rod 201, and a cleaning roller 202 is slidably installed on the outer wall of the concave ring 203. The concave ring 203 and the cleaning roller 202 are engaged with each other, which can prevent the cleaning roller 202 from rotating while not affecting the sliding of the cleaning roller 202. The sliding cleaning roller 202 will not block the expansion joint 108 from sliding on the outer wall of the fixed roller 107.

[0032] Among them, the cleaning roller 202 is attached to the outer wall of the expansion joint 108, and there are four hydraulic cylinders 102. The four hydraulic cylinders 102 are respectively installed at the four corners of the partition 103. The outer wall of the expansion joint 108 can be cleaned by the cleaning roller 202. The lifting and lowering of the hydraulic cylinder 102 can lower the partition 103 and thus lower the transverse movement assembly 104, which can separate the transverse movement assembly 104 from the expansion joint 108.

[0033] Furthermore, the transverse movement assembly 104 includes a slide plate 104a, which is fixedly installed on the top of the partition 103. A clamping plate 104b is slidably installed on the inner side of the slide plate 104a. A threaded sleeve 104d is fixedly installed on the bottom of the clamping plate 104b. A threaded rod 104c is threadedly installed on the inner wall of the threaded sleeve 104d. A second motor 104e is fixedly installed on one side of the threaded rod 104c. The expansion joint 108 is fixedly controlled to slide through the clamping plate 104b, so that the fixed roller 107 cleans the inner wall of the expansion joint 108.

[0034] Furthermore, the second motor 104e is fixedly installed at the bottom of the partition 103, the clamping plate 104b is clamped on one side of the expansion joint 108, and the expansion joint 108 is fixedly connected through the clamping plate 104b, and then the threaded rod 104c is driven by the second motor 104e to drive the expansion joint 108 to slide on the outer wall of the fixed roller 107.

[0035] Furthermore, a through-hole slot is provided inside the partition 103, and the threaded sleeve 104d is slidably installed with the partition 103 through the through-hole slot. The through-hole slot can limit the rotation of the threaded sleeve 104d, making it convenient for the threaded rod 104c to drive the threaded sleeve 104d to move.

[0036] Furthermore, a mounting plate is fixedly mounted on the bottom of the partition 103, and one side of the mounting plate is rotatably mounted with the threaded rod 104c. The mounting plate can facilitate the rotation of the threaded rod 104c and stabilize the position of the threaded rod 104c.

[0037] During use, the expansion joint 108 is first inserted into the outer wall of the fixed roller 107, and the cylindrical block of the transmission ring 109 is inserted into the threaded hole of the flange. Then, the hydraulic cylinder 102 drives the partition plate 103 to move upward, thereby driving the slide plate 104a and the clamping plate 104b to move upward, and then the clamping plate 104b is stuck on the outer wall of the flange of the expansion joint 108. Then, the electric telescopic rod 105 drives the cleaning roller 202 to move downward, so that the cleaning roller 202 fits the outer wall of the expansion joint 108;

[0038] During cleaning, the first motor 106 drives the expansion joint 108 to rotate through the transmission ring 109, so that the outer wall of the expansion joint 108 is cleaned by the cleaning roller 202. When cleaning the expansion joint 108, the second motor 104e drives the threaded rod 104c to rotate, and the threaded sleeve 104d is driven to move by the threaded rod 104c, and the splint 104b is driven to move by the threaded sleeve 104d, thereby driving the expansion joint 108 to move. When the expansion joint 108 moves, the fixed roller 107 slides relative to the inner wall of the expansion joint 108 to clean the inner wall of the expansion joint 108.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
