Description

Buret scriber for water heating maintenance

Technical Field

The utility model belongs to the technical field of water heating maintenance equipment, and particularly relates to a water heating maintenance dosage pipe scriber.

Background

In the maintenance process of a water heating pipe network, a section of pipeline with serious damage or corrosion and leakage points is frequently required to be replaced, and the replacement length is generally between 20 cm and 100 cm according to the number of the leakage points or the damage degree; or a tee joint is additionally arranged according to the heating requirement of the pipe network. When a pipe is replaced or a tee joint is additionally arranged, firstly, a worker uses a meter ruler to measure the length of the tee joint or a replacement pipe, and then uses a mark to mark a cutting line on a pipeline to break the pipe; and secondly, directly placing the tee joint or the substitution tube on a pipeline, and using a marking pen to stroke a cutting line to break the tube. If the broken pipe is an iron pipe, the weld joint can be larger due to the existence of the error, and the welding quality of the pipeline is affected; if the broken pipe is a hot melting pipe, the hot melting effect can be affected when the pipe joint gap is larger. If the tee joint or the replacing pipe is directly placed on the pipeline to draw a line and break the pipe, although the measurement error can be reduced, the cutting line is easily drawn and deviated due to the fact that the replacing pipe or the tee joint is not easy to hold in the line drawing process, and then the effect of breaking the pipe and the quality of a connecting pipe can be affected.

Detailed Description

Examples

Referring to fig. 1 to 5, a buret line drawing device for water heating maintenance comprises a fixed chuck 1 and a sliding chuck 2; the fixed chuck and the sliding chuck are respectively provided with a first semicircular clamping groove 11, a second semicircular clamping groove 12, a third semicircular clamping groove 13, a fourth semicircular clamping groove 14, a fifth semicircular clamping groove 15 and a sixth semicircular clamping groove 16, the center of the fixed chuck is welded with a sliding rod 17, and the sliding rod is provided with a sliding groove 18; a sliding sleeve 20 is welded in a central hole of the sliding chuck, a sliding block 23 is arranged in an inner hole of the sliding sleeve, a threaded column 21 is arranged outside the sliding sleeve, and a set screw 22 is arranged in the threaded column; the sliding chuck is sleeved on the sliding rod, is limited in the circumferential direction through a sliding block which is inserted in the sliding groove in a sliding way, and is limited in the axial direction through a set screw, and a semicircular clamping groove on the sleeved sliding chuck corresponds to a semicircular clamping groove on the fixed chuck; after the sliding chuck is sleeved with the fixed chuck, the circle centers of the corresponding semicircular clamping grooves on the two chucks are on the same antenna; the radii of the first semicircular clamping groove, the second semicircular clamping groove, the third semicircular clamping groove, the fourth semicircular clamping groove, the fifth semicircular clamping groove and the sixth semicircular clamping groove are respectively 15 mm, 20 mm, 25 mm, 30 mm, 35 mm and 40 mm; the set screw is a straight-headed screw; the length of the sliding rod is not less than 300 mm; the diameter of the sliding rod is not more than 15 mm.

Taking the replacement of a leakage point iron pipe with the length of about 300 mm and the outer diameter of 56 mm in a water heating pipe network as an example. Firstly, cutting an iron pipe (the outer diameter is 56 mm) with the length of about 300 mm, then attaching a fixed chuck to one end of the iron pipe, sleeving a sliding chuck on a sliding rod (the sliding rod is arranged outside the iron pipe), enabling two chucks to be attached to two ends of the iron pipe, screwing a set screw to lock the sliding chuck, and then removing the iron pipe. And clamping the two chucks with fixed relative positions on the pipeline to draw a cutting line, wherein the pipeline with the outer diameter of 56 mm is clamped on the pipeline by using a fourth semicircular clamping groove with the radius of 30 mm.
