Problems solved by technology

[0003] The purpose of the present invention is: in the existing pipeline construction process, since there is no special tool for drawing intersecting lines, it is necessary to draw intersecting lines by hand or sample pipes, and because this method has troubles, and the marking accuracy is relatively low. low, which is not conducive to the defects of pipeline construction, the present invention provides a new type of marking tool specially used for drawing intersecting lines at pipeline joints

Embodiment Construction

[0009] In the figure, the tool for marking the intersecting line at the pipe joint includes a magnetic lock 1, a support rod 2, a lock nut 3, a connecting bridge 4, a crank 5, a bearing 6, a central shaft 7, a rotating arm 8, and a drawing needle cylinder 9. Spring 10, drawing needle 11, positioning screw sleeve 12, pipeline workpiece 13, lock nuts 3 are used to symmetrically fix and install support rods 2 in the chute at both ends of the connecting bridge 4, and at the bottom of each support rod 2 A magnetic lock 1 is fixedly installed, and the magnetic lock 1 is a V-shaped structure. A central axis 7 is fixedly installed through a bearing 6 in the middle of the connecting bridge 4. The central axis 7 and the connecting bridge 4 are in a perpendicular relationship with each other. The bottom of 7 is fixedly installed with rotating arm 8, and the relationship between rotating arm 8 and central axis 7 is mutually perpendicular. In the chute of rotating arm 8, a drawing ne...

Abstract

The invention discloses a pipeline connection position intersecting line marking tool. Supporting rods are symmetrically and fixedly arranged in sliding chutes arranged at two ends of a connection bridge through locking nuts, and a magnetic lock of a V-shaped structure is fixedly arranged at the bottom of each supporting rod. A center shaft is fixedly arranged in the middle of the connection bridge through a bearing, a rotating arm is fixedly arranged at the bottom of the center shaft, and a marking awl barrel is vertically fixedly arranged in a sliding chute of the rotating arm. A spring and a marking awl are arranged on the inner portion of the marking awl barrel; and the marking awl is fixed in the marking awl barrel through a positioning screw sleeve. The pipeline connection position intersecting line marking tool has the advantages of being convenient in marking awl intersecting line and high in marking accuracy, and can effectively facilitate pipe construction and production.

Description

technical field [0001] The invention relates to a pipeline tool technology, in particular to a pipeline marking tool for intersecting lines at joints. Background technique [0002] In the process of pipeline construction, the connection relationship between pipelines is often prepared on the construction site, that is: according to the connection relationship between pipelines, draw intersecting lines at the joints of pipelines, and draw intersecting lines Remove the excess material of the network, and then move the connected pipes to the mouth of the intersecting line, and then weld the pipes firmly. At present, in the field of pipeline construction, there is no special tool for drawing the connecting intersecting lines between pipelines. Generally, manual or sample pipe methods are used to draw connecting intersecting lines between pipelines. Therefore, there are not only troublesome shortcomings, but also Fortunately, the accuracy of the drawn intersecting ...
