Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:
as shown in fig. 1 and 2, the utility model provides a central point puts detection mechanism before "pipe in pipe" formula insulating tube shutoff, this mechanism can install on the plugging machine, detects the position at work steel pipe center for shutoff end cover center before the shutoff, provides feedback information for the regulation of end cover position.
In order to solve the technical problem, the utility model discloses a following embodiment:
the central position detection mechanism before the pipe-in-pipe type heat preservation pipe is plugged consists of a sensor seat (3), a reflection type laser ranging sensor (4), a conductive sliding ring (5), a semicircular hoop (6), a mounting bracket (7), a coupler (8), a stepping motor (9), a bracket (10), a rotor flange (11) and a mandrel (12). The sensor seat (3) is of a square five-face box type structure, four reflection type laser ranging sensors (4) are symmetrically arranged at the central positions of four vertical faces of the sensor seat (3) respectively, and each sensor is fixed through an inner nut and an outer nut respectively. The bottom surface of the sensor seat (3) is fixed with a rotor flange (11) of the conductive slip ring (5) through a mandrel (12) and two limiting bolts. The stator of the conductive slip ring (5) is fixed on the bracket (10) through two semicircular hoops (6) and bolts. The bracket (10) and the mounting bracket (7) are of an integral welding structure. The mandrel (12) penetrates through a center hole of the conductive slip ring (5), the rear end of the mandrel (12) is connected with an output shaft of the stepping motor (9) through a coupling (8), and the stepping motor (9) is fixed on the mounting bracket (7) through four bolts.

With reference to fig. 1 and 3, the working process of the "tube-in-tube" type heat preservation tube center position detection mechanism before plugging is as follows:
the central position detection mechanism is arranged on the plugging machine, and the central line of the central position detection mechanism is superposed with the central line of the end cover. Before plugging, the plugging machines at the two ends of the thermal insulation pipe to be foamed feed to the two end surfaces of the thermal insulation pipe. Before the central position detection mechanism does not enter the working steel pipe, the data detected by the four reflection-type laser ranging sensors are relatively random. When the error among the data detected by the four reflection-type laser ranging sensors reaches a set range, the fact that the detection head of the central position detection mechanism enters the working steel pipe is indicated, the plugging machine stops feeding at the position, and the detection of the central position of the working steel pipe is implemented.
During detection, the signal acquisition system firstly acquires the distance data of 4 laser ranging sensors at the current position, and then the stepping motor drives the detection head to rotate 45OAnd the signal acquisition system acquires 4 distance data. After the detection is finished, the central positions of the 8 data are calculated by adopting a mathematical method, and further the position information of the center of the working steel pipe relative to the center of the end cover is obtained.
And (III) after the detection is finished, adjusting the position of the end cover according to the position condition of the center of the working steel pipe relative to the center of the end cover, wherein the error of the two center positions is within an allowable range, and performing the action of sleeving the end cover. Simultaneously, the stepping motor is rotated to an initial position.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments, which are only illustrative and not restrictive, and those skilled in the art can make various changes without departing from the spirit and the scope of the present invention.
