Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] Such as Figure 1-Figure 5 As shown, a collection vehicle for detecting small-angle intersecting line welds described in this embodiment includes a base 1, wherein the base 1 is U-shaped, and the bottom of the base 1 is provided with absorbable and A walking mechanism 2 that walks on the surface of the pipe to be tested. The base 1 is provided with a probe 3 that can be attached to the surface of the pipe to be tested and used to detect intersecting line welds. The front of the base 1, the rear side of the base 1 is provided with a height adjustment mechanism 5 for adjusting the lifting of the base 1.

[0025] The walking mechanism 2 includes a driving wheel 21 and a driven wheel 22, the driving wheel 21 includes a controllable driving magnetic wheel 211, and the driven wheel 22 includes a d...

Abstract

The invention discloses a collecting vehicle for detecting a small-angle intersecting-line weld seam. The collecting vehicle comprises a base, wherein the base is in a U shape. A walking mechanism capable of being attracted to and walking on the surface of a to-be-detected pipe is arranged at the bottom of the base; a probe capable of being attached to the surface of the to-be-detected pipe and used for detecting the intersecting-line weld seam is arranged on the base, and is fixed to the front of the base through an angle adjusting mechanism; a height adjusting mechanism for adjusting ascending and descending of the base is arranged on the back side of the base. As the collecting vehicle for detecting the small-angle intersecting-line weld seam comprises the U-shaped base, the height of the collecting vehicle is reduced, and the collecting vehicle can enter narrow and small space; as the walking mechanism capable of being attracted to and walking on the surface of the to-be-detected pipe is arranged at the bottom, the collecting vehicle can stay on any curved surface and walk along any path of the curved surface; as the angle adjusting mechanism and the height adjusting mechanism are arranged, the constant distance, the constant angle and the constant contact pressure between the probe and the weld seam can be invariably kept.

Description

technical field [0001] The invention relates to a collection vehicle, in particular to a collection vehicle for small-angle intersecting line weld detection. Background technique [0002] When fittings are connected to fittings, the junction between the two fittings forms a line of intersection. Since the intersecting line is an ever-changing spatial curve, the bevel and gap of the same intersecting mouth also change accordingly. Therefore, the welding and detection of intersecting line welds are difficult. The utility model with the patent number CN204269611U discloses "an automatic detection trolley for intersecting line welds", which can accurately detect intersecting line welds, and can absorb and walk freely and stably. However, the head of this kind of trolley is relatively high, and it cannot enter the gap at the joint of the pipe fittings where the pipe fitting angle is less than 30°, so the weld in the narrow gap cannot be detected.
