Abstract
The utility model relates to a polyurethane elastic probe arm used for fixing and supporting a probe on a pipeline detector, which belongs to the technical field of the pipeline system for measuring the magnetic variable and the linear thickness size. The polyurethane elastic probe arm is a polyurethane integral injection-moulded plate sheet which takes an S-shape in space with the straight middle part and two bent sides and comprises an A section, a B section and a C section from bottom to top; two through holes are arranged at the middle part of the A section at the lower part, a rectangular slotted hole is arranged in the middle part at one side of the C section at the upper part, two circular step posts are arranged in the slotted hole, and the slotted hole is communicated with a trough which passes through the B section all the time. The utility model has the advantages of simple structure, convenient disassembly and assembly and stable performance.
Description
Technical field
The utility model is a kind of elastic polyurethane probe arm that is used for fixing on the pipe detector and supporting probe.Relate to measurement and the piping system technical field of measuring magnetic variable, thickness linear dimension.
Background technology
At present, the corrosion that pipe corrosion detector is widely used in various conveyance conduits detects, and for the pipeline owner has obtained real pipe corrosion condition data, also provides the foundation of science for the correct maintenance of pipeline.Most important parts are no more than the corrosion probe assembly on the pipe corrosion detector, and it comprises contact unit, probe wear-resisting slide plate unit and the probe arm and the spring unit that support them.Traditional probe arm unit all be designed to can be movable the hinge type steel construction, the rigidity torsion spring that supports usefulness or copper spring sheet etc. are installed in the bottom of steel probe arm then, also wear-resisting slide plate to be installed in probe arm and pipeline arm contact part, not sustain damage with the probe components and parts of wear-resisting slide plate bottom behind the assurance long distance running.This traditional probe arm member exists many shortcomings such as complicated in mechanical structure, dismounting inconvenience, the wear-resisting distance of wear-resisting slide plate weak point, steel spring easy deformation.
The utility model content
The purpose of this utility model is that the pipe detector of a kind of simple in structure, easy accessibility of design, stable performance is with the elastic polyurethane arm of popping one's head in.
Structure of the present utility model is shown in Fig. 1-4, and it is a polyurethane integral injection moulding plate.Spatially become the serpentine shape of middle part straight both sides bending, form for three sections by from top to bottom A, B, C; At the A of bottom section middle part 2 through holes are arranged.
For compactness, save the space, the compatible space that probe circuit plate unit is installed, C section one middle side part on top has the rectangle slotted eye, and trough connects the B section always to have 2 round platform rank posts, this slotted eye to communicate also with trough in slotted eye.
Consider that from the function of probe arm among three sections of this A, B, the C, the A section of bottom is narrow, the C section on top is wide, and middle B section then is the transition section from the A section to the C section, is divergence form from narrow to wide on Width.
On function, the A section is what to be used for fixing at the drum surface of circumference type, and the B section is a supporting section, play and support and the elastic deformation effect, and the C pars infrasegmentalis has a square slotted eye, and probe circuit plate unit is installed, the direct and pipeline inner arm contact wear in top.
As seen, the utility model is simple in structure, easy accessibility, stable performance.

Embodiment
Embodiment. this example is the elastic polyurethane probe arm of Φ 219mm high definition pipe leakage detector.Its structure is shown in Fig. 1-4, and it is a polyurethane integral injection moulding plate, the thick 10mm of plate.Spatially become the serpentine shape, be made up of for three sections ABC, bottom A section is narrower, top C section broad, and middle B section then is the transition section from the A section to the C section, is divergence form from narrow to wide on Width.At the middle part of A section 2 through holes are arranged, there is the rectangle slotted eye at the middle part of C section one side, and trough connects the B section always to have 2 round platform rank posts, this slotted eye to communicate also with trough in slotted eye.
External diameter according to pipeline, 16 probe arm will distribute on the circular cylinder body outside surface, because the circular cylinder body diameter is little more a lot of than internal diameter of the pipeline, so width 16mm of A section, C section width 29mm, otherwise the probe arm of the some that do not distribute also just can not guarantee the coverage rate of popping one's head on the inner-walls of duct circumference.A and C section all are that the B section has been exactly a transition section naturally so uniformly on width for every section separately, and width evenly increases, and is increasing.Design has two through holes on the A section of probe arm, is used for screw and penetrates the probe arm is fixed on the circular cylinder body outside surface.
For probe circuit plate unit being fixed on below the C section, adopted the most simple mode, have the slotted eye of a rectangle exactly in the Lower Half of C section thickness, circuit board unit is cast directly in the slotted eye with epoxy resin, this is than convenient and much simple with bolt.For the probe circuit plate is located well, Front-end Design at slotted eye has two step posts, the diameter of step post, highly all consistent with the hole and the height of plank on the circuit board, and the probe circuit plate is inserted on the step post like this, when casting epoxy resin, can not move, can reach preposition and height.All design a width and the degree of depth on from C section slotted eye to the whole length of B section and all be the trough about about 6-10mm, can tie up to the drum surface of static probe arm along this trough from the line that the probe circuit plate comes out.
In order to obtain support elastic preferably, B section and A section have an angle greater than 90 degree.The angle of the probe arm that certainly, different outer diameter tube detecting devices is used is also not exclusively the same.In addition, C section and B section also have the angles greater than 90 degree, and this is in order to allow C section end that a pretightning force that makes progress can be arranged, and the probe of C pars infrasegmentalis can be close to inner-walls of duct like this, has guaranteed the accuracy of image data.
Through evidence, this elastic polyurethane probe arm good springiness, distortion are stable, install and use simplely, and novel structure is simple.
