Description

Underground heating pipe bends and stops up clearance mechanism

Technical Field

The invention relates to the technical field of municipal heating pipeline cleaning equipment, in particular to a mechanism for cleaning blockage at a bent part of an underground heating pipeline.

when the device works, a worker starts the servo motor 810, under the transmission action of the belt pulley transmission mechanism 820, the steel cable 260 rotates to drive the gear 250 to rotate, the rotating plate 220 rotates through the engagement of teeth between the gear 250 and the inner gear ring 240 to drive the blades 320 to rotate, when the blades 320 rotate, the worker synchronously pushes the main support tube 100 into the pipeline to enable the blades 320 to rotate to break into impurities, and because two adjacent groups of breaking mechanisms 300 are connected through the connecting mechanism 500, the two corresponding groups of fixed cylinders 510 are mutually perpendicular, the two adjacent groups of fixed cylinders 510 can be flexibly rotated and adjusted, so that the device can pass through at the bent position of the pipeline;

when the device runs through the position of the impurity at the bent part inside the pipeline, a worker stops supplying power to the servo motor 810 to stop rotating the blade 320, then holds the cable 410 and conveys the cable to the inside of the pipeline, so that the cable 410 moves to drive the limiting piece 430 to move out of the guide head 600, after the limiting piece 430 moves out, the outer side of the cable loses the limitation, under the elastic pulling action of the expansion spring 437, the second support rod 434 moves to drive the first support rod 433 to deflect, the first support rod 433 and the second support rod 434 form a triangle through rotation and are clamped at the outer side of the guide head 600, then the worker pulls the cable 410 outwards, as the position of the limiting piece 430 is limited, the fixed block 420 moves through the pulling of the cable 410, under the extrusion action of the fixed block 420, the elastic net 440 is deformed into a flat cake shape and is blocked at one side of the impurity, the worker pulls the main support pipe 100 and the cable 410 simultaneously, the impurities are drawn out and the hot steam is discharged from the exhaust pipe 840 through the inside of the main support pipe 100, which is the overall operation principle of the present invention.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
