Description

Technical Field

[0001] The invention relates to the technical field of bellows detection, in particular to a multi-specification self-propelled detection mechanism applied to bellows. Background Art

[0002] A bellows is a tubular connector with foldable corrugations that can be stretched and retracted along the folding direction. Because it has a cylindrical thin-walled fold with multiple transverse corrugations, it can produce displacement under the action of pressure, axial force, transverse force or bending moment. It is widely used in the fields of electricity, chemical industry, and machinery.

[0003] Currently, after the processing and production of bellows, in order to ensure that its internal dimensions meet the production requirements, the inner and outer walls of the pipe fittings need to be inspected. The traditional inspection method is to inspect the outer wall of the bellows through manual operation, but it is impossible to inspect the inner wall of the bellows, especially for pipe fittings with relatively long lengths, resulting in large inspection limitations and poor operability. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the current detection method for bellows is to detect the outer wall of the bellows through manual operation, but it is impossible to detect the inner wall of the bellows, especially for pipes with a relatively long length, resulting in large detection limitations and poor operability.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a multi-specification self-propelled detection mechanism applied to corrugated pipes, including an internal main frame and an optical detection module, two split drive wheel groups are movably connected on both sides of the internal main frame, an electrically controlled lifting seat is installed on the lower surface of the internal main frame, a detachable external adjustment ring for installing the optical detection module is installed inside the electrically controlled lifting seat, and an embedded counterweight base plate is fixedly installed on the lower surface of the internal main frame.

[0006] The split drive wheel assembly includes an internal rotating shaft movably mounted on one side of the internal main frame through an internal rotating shaft, lateral assembly wheel discs axially fixed on both sides of the internal rotating shaft, a drive motor fixed inside the internal main frame, an external wheel sleeve axially sleeved and fixed on the outside of the lateral assembly wheel disc, and an embedded guide wheel movably mounted on the inner wall of the groove outside the external wheel sleeve.

[0007] A bottom lifting groove for accommodating an electric-controlled lifting seat is provided on the lower surface of the internal main frame.

[0008] The electrically controlled lifting seat comprises a first top lifting strut fixed on the upper surface of the internal main frame, a second top lifting strut, a bottom lifting assembly frame fixed on the bottom extending end of the first top lifting strut, a top lifting limiting wheel set fixed on the bottom extending end of the second top lifting strut, and a lateral translation limiting wheel set slidably assembled on both sides of the bottom lifting assembly frame.

[0009] A lateral loading and unloading opening is arranged on the outer side of the bottom lifting assembly frame.

[0010] A plurality of lateral mounting holes for mounting the optical detection module are provided on the outer side surface of the detachable external adjustment ring, and lateral locking bolts for fixing the optical detection module are installed on the side wall of the detachable external adjustment ring.

[0011] Arc-shaped sinking grooves are symmetrically provided at both ends of the inner and outer arc-shaped surfaces of the detachable external adjustment ring.

[0012] The bottom of both sides of the bottom lifting assembly frame are provided with strip guide openings for slidingly assembling the lateral translation limiting wheel group. The lateral translation limiting wheel group includes a sliding adjustment frame slidably inserted in the strip guide opening, a lateral adjustment bolt threadedly assembled on the outside of the bottom lifting assembly frame, and a bottom side extrusion roller movably installed inside the sliding adjustment frame.

[0013] The top lifting and limiting wheel set comprises a lifting frame fixed to the bottom extended end of the second top lifting support rod and an electric drive wheel movably installed in the lifting frame.

[0029] In order to cooperate with the lateral adjustment drive, the split drive wheel group 4 includes an internal rotating shaft 41 movably installed on one side of the inner main frame 1 through an internal rotating shaft, a lateral mounting wheel disc 42 axially fixed on both sides of the internal rotating shaft 41, a driving motor 43 fixed inside the internal main frame 1, an external wheel sleeve 44 axially sleeved and fixed on the outside of the lateral mounting wheel disc 42, and an embedded guide wheel 45 movably installed on the inner wall of the outer groove of the external wheel sleeve 44.

[0030] The driving shaft of the driving motor 43 meshes with the driven gear on the outside of the internal rotating shaft 41 through the driving gear, and the internal rotating shaft 41 is driven to rotate by the driving motor 43, so that the side assembly wheel plate 42 drives the external wheel sleeve 44 to rotate. The external wheel sleeve 44 has an arc-shaped protrusion on the outside, and the external wheel sleeve 44 is inserted into the inner groove of the corrugated tube through the arc-shaped protrusion and then moves inside the corrugated tube in cooperation with the internal main frame 1, and then the embedded guide wheel 45 automatically slides to the inner bottom surface of the corrugated tube, and then the embedded counterweight bottom plate 7 is used for counterweighting to improve stability. Different external wheel sleeves 44 and detachable external adjustment rings 6 are replaced according to different corrugated tubes.

[0031] In order to facilitate the telescopic adjustment and storage of the bottom, a bottom lifting groove 8 for accommodating the electric-controlled lifting seat 5 is opened on the lower surface of the internal main frame 1 .

[0032] In order to cooperate with the lifting and lowering adjustment, the electrically controlled lifting seat 5 includes a first top lifting support rod 51 fixed on the upper surface of the internal main frame 1, a second top lifting support rod 52, a bottom lifting assembly frame 53 fixed to the bottom protruding end of the first top lifting support rod 51, a top lifting limiting wheel group 54 fixed to the bottom protruding end of the second top lifting support rod 52, and a lateral translation limiting wheel group 55 slidably assembled on both sides of the bottom lifting assembly frame 53.

[0033] In order to facilitate lateral loading and unloading, a lateral loading and unloading opening 56 is provided on the outer side of the bottom lifting assembly frame 53 .

[0034] The first top lifting strut 51 is telescopically controlled to lift the bottom lifting assembly frame 53 at the bottom extending end, and the second top lifting strut 52 is telescopically controlled to lift and adjust the top lifting limit wheel set 54 at the bottom extending end.

[0035] The detachable external adjustment ring 6 is inserted into the bottom lifting assembly frame 53 from the side loading and unloading port 56, and then the second top lifting support rod 52 controls the top lifting limit wheel group 54 at the bottom protruding end to squeeze the inner curved surface of the detachable external adjustment ring 6, and the bottom lifting assembly frame 53 translates from both sides to squeeze the outer curved surface of the detachable external adjustment ring 6.

[0036] In order to cooperate with lateral assembly and loading and unloading fixing, four lateral mounting holes for mounting the optical detection module 2 are opened on the outer side surface of the detachable external adjustment ring 6, and lateral locking bolts 61 for fixing the optical detection module 2 are installed on the side wall of the detachable external adjustment ring 6.

[0037] In order to improve the lateral limit and the extrusion limit, arc-shaped sinking grooves 62 are symmetrically provided at both ends of the inner and outer arc-shaped surfaces of the detachable external adjustment ring 6 .

[0040] In order to cooperate with the top limit and drive, the top lifting limit wheel group 54 includes a lifting frame 541 fixed to the bottom protruding end of the second top lifting support rod 52 and an electric drive wheel 542 movably installed in the lifting frame 541.

[0041] The second top lifting support rod 52 controls the lifting and lowering of the lifting frame 541 by telescoping, and then the arc-shaped sinking grooves 62 at both ends of the inner arc surface of the detachable external adjustment ring 6 are squeezed by the electric drive wheel 542, so as to control the rotation adjustment of the detachable external adjustment ring 6, and then the detachable external adjustment ring 6 drives the surface optical detection module 2 to move along a circle by rotating, and then the optical detection module 2 is used to perform surrounding detection on the surface of the corrugated tube. The optical detection module 2 is a laser ranging module, and the surrounding optical detection is performed by rotating the detachable external adjustment ring 6, so as to measure the distance of the inner wall of the corrugated tube and the damage of the inner wall.
