Abstract

The utility model relates to a joint pipe and a holing line-marking device, which mainly solves the problems of poor line-marking accuracy and low work efficiency of the prior art and is characterized in that a scriber (1) is arranged in a sleeve (3) with two banking screws (2). A ruler (4) with scales is connected outside the sleeve (3) in a horizontal direction. A connecting rod (7) of the lower end of a vernier (6) with a fastening screw (5) on the ruler (4) is connected with a magnetic seat (9) with a magnetic switch (8). The magnetic seat (9) is horizontally fixed with a semicircular angle meter (10). A pointer (11) on the connecting rod (7) points to scales of the angle meter (10). The joint pipe and a holing line-marking device has the advantages of high precision during marking a line, low labor intensity of workers and high work efficiency.

Description

Take over and the perforate chalker
Technical field:
The utility model relates to used perforate scoring tool in oil field, chemical industry, the pipeline installation field such as public, especially takes over and the perforate chalker.
Background technology:
In pipe-line construction, on pipeline or on the pressure vessel in succession with the footpath or during reduced pipe, need perforate on pipeline or pressure vessel, and need on pipeline or pressure vessel, mark the crossing line of hat mutually before the perforate.Do not have special-purpose scoring tool at present, the workman adopts the method for retouching by pattern or full pattern to draw and is preced with line mutually, adopts this method to exist the problem of low precision, influence product quality, and labor strength is big, inefficiency.
The utility model content:
In order to overcome existing line low precision and ineffective deficiency, the utility model provides sharp an adapter and the perforate chalker, this adapter and perforate chalker precision height not only when line, and also labor strength is low, high efficiency.
The technical solution of the utility model is: this adapter and perforate chalker comprise scriber, scriber places in the sleeve with two stop screws, sleeve is horizontally connected with the ruler of band scale outward, the connecting rod of the vernier lower end of band trip bolt links to each other with the magnetic support of band magnetic switch on the ruler, crosswise fixed has semicircle protractor on the magnetic support, the pointed protractor scale on the connecting rod.
The beneficial effect that the utlity model has is: this adapter and perforate chalker are owing to adopted such scheme, when line, make radius by the scale on the ruler, the throughput hornwork is made angle, so just can improve the line precision greatly by ruler and protractor, and increase work efficiency, reduced labor strength.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-scriber among the figure, 2-stop screw, 3 sleeves, 4-ruler, 5-trip bolt, 6-vernier, 7-connecting rod, 8-magnetic switch, 9-magnetic support, 10-protractor, 11-pointer.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this adapter and perforate chalker comprise scriber 1, and scriber 1 places in the sleeve 3, sleeve 3 is with two stop screws 2, be horizontally connected with ruler 4 outside the sleeve 3, have scale on the ruler 4, be with vernier 6 on the ruler 4, have trip bolt 5 on the vernier 6, vernier 6 lower ends are connected with connecting rod 7, and connecting rod 7 lower ends link to each other with magnetic support 9, and magnetic support 9 right sides have magnetic switch 8, crosswise fixed has semicircle protractor 10 on the magnetic support 9, and the pointer 11 on the connecting rod 7 points to protractor 10 scales.This device is adsorbed on by magnetic support 9 to be needed on the scribing position, make radius by the scale on the ruler 4 then, throughput hornwork 10 is made angle, after determining to take over the center of circle, radius and angle, open stop screw 2, scriber is dropped on the surface of pipeline or pressure vessel, rotation ruler 4 just marks the needed line of being preced with mutually on the surface of pipeline or pressure vessel, so just can improve the line precision greatly by ruler 4 and protractor 10, and increase work efficiency, reduced labor strength, used easy to operate.

Claims (1)

1, a kind of adapter and perforate chalker, comprise scriber (1), it is characterized in that: scriber (1) places in the sleeve (3) with two stop screws (2), the outer ruler (4) that is horizontally connected with the band scale of sleeve (3), the connecting rod (7) that ruler (4) is gone up vernier (6) lower end of band trip bolt (5) links to each other with the magnetic support (9) of band magnetic switch (8), magnetic support (9) is gone up crosswise fixed semicircle protractor (10), and the pointer (11) on the connecting rod (7) points to protractor (10) scale.
