[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples.

[0022] As shown in the attached Figure 1 to the attached Figure 5 figure:

[0023] Embodiment 1: The present utility model provides a new type of row-connected branch pipe positioning device, including a pipe body positioning assembly 1. The pipe body positioning assembly 1 includes a positioning plate 101, a connecting rod 102 and a positioning rod 103. The bottom end of the connecting rod 102 is fixedly installed on the top of the positioning plate 101, and the top end of the connecting rod 102 is fixedly connected to the bottom of the positioning rod 103. There are two groups of the positioning plate 101 and the connecting rod 102, and the two groups of the positioning plate 101 and the connecting rod 102 are symmetrically arranged on both sides of the bottom of the positioning rod 103; a branch pipe positioning assembly 2, the branch pipe positioning assembly 2 includes a positioning sleeve 201, a support nut 202, a loose clamping screw 203 and a connecting branch pipe 204. The positioning sleeve 201 is inserted into the inside of the positioning rod 103, and the support nut 202 is inserted into the side of the positioning rod 103 along the direction of the positioning rod 103. The loose clamping screw 203 is inserted into the inside of the positioning rod 103 along the radial direction of the positioning sleeve 201, and the connecting branch pipe 204 is inserted into the inside of the positioning sleeve 201. The loose clamping screw 203 is screwed into the inside of the support nut 202 through a thread; there are four groups of the branch pipe positioning assembly 2, the number is not limited to four groups, and the number can be increased or decreased.

[0024] In the embodiments of the present disclosure, a reference line 1011 is provided on the plate body of the positioning plate 101 along the long side direction of the positioning rod 103, and the reference lines 1011 of the two positioning plates 101 are on the same horizontal straight line. When the two reference lines 1011 coincide with the straight line drawn in the vertical direction of the pipeline on the main pipeline by a laser level and a line drawing ink fountain, it means that the positioning rod 103 is in a parallel state with the main pipeline, which is convenient for subsequent construction.

[0025] In the embodiments of the present disclosure, a positioning through groove 1031 is provided inside the positioning rod 103, and the positioning sleeve 201 is inserted into the positioning through groove 1031. The cross-sectional shape of the positioning sleeve 201 is "T"-shaped, and positioning bosses 1032 are provided on both sides of the top of the positioning rod 103. When the positioning sleeve 201 is inserted into the positioning through groove 1031, the top of the positioning sleeve 201 rests on the top of the positioning bosses 1032. A support groove 1033 is provided inside the positioning rod 103, and the support nut 202 is inserted into the support groove 1033. The rod body of the loose clamping screw 203 passes through the positioning rod 103, and one end of the loose clamping screw 203 can abut and press against the side surface of the positioning sleeve 201 after being tightened. During use, by tightening or loosening the loose clamping screw 203, the use position of the branch pipe positioning assembly 2 on the positioning rod 103 can be realized, and at the same time, parameters such as the distance and position between multiple groups of branch pipe positioning assemblies 2 can also be adjusted. When the loose clamping screw 203 is loosened, the loose clamping screw 203 does not abut against the side surface of the positioning sleeve 201 to apply pressure to the support nut 202. Therefore, at this time, the branch pipe positioning assembly 2 can move freely inside the positioning rod 103. When the branch pipe positioning assembly 2 moves to a suitable position, the loose clamping screw 203 is tightened. One end of the loose clamping screw 203 can abut against the top of the positioning sleeve 201 after being tightened, and pressure is applied to the support nut 202 through the abutting force to fix it inside the support groove 1033, thereby realizing the overall fixation of the branch pipe positioning assembly 2. It is convenient and flexible to use. Through the above method, the adjustment and positioning operation of each branch pipe positioning assembly 2 can be realized, and it is convenient to use.

[0026] In the embodiments of the present disclosure, the axis of the positioning sleeve 201 is perpendicular to the horizontal connection line of the two reference lines 1011, and the axis of the positioning sleeve 201 and the reference line 1011 are in the same vertical plane. During use, the connecting branch pipe 204 is inserted into the positioning sleeve 201 and guided by the positioning sleeve 201. Since the axis of the positioning sleeve 201 is always perpendicular to the reference line 1011 after assembly, the perpendicularity (horizontal degree) of the connecting branch pipe 204 after being welded to the main pipe is ensured, the construction specification is met, and the connection quality of the pipeline is improved.

[0027] Specific usage and functions of this embodiment:

[0028] In the utility model, a laser level and a line-laying ink fountain are used to draw a straight line in the vertical direction of the main pipeline, and then the use position of the branch pipe positioning component 2 on the positioning rod 103 is adjusted according to the processing requirements. The use position of the branch pipe positioning component 2 on the positioning rod 103 can be achieved by tightening or loosening the clamping screw 203, and the spacing, position and other parameters between multiple groups of branch pipe positioning components 2 can also be adjusted. When the clamping screw 203 is loosened, the clamping screw 203 will not resist the side of the positioning sleeve 201 to apply pressure to the support nut 202, so that the branch pipe positioning component 2 can move freely inside the positioning rod 103 at this time. When the branch pipe positioning component 2 moves to a suitable position, the clamping screw 203 is tightened. After the clamping screw 203 is tightened, one end of the clamping screw 203 can resist the top of the positioning sleeve 201, and the resistance force is used to apply pressure to the support nut 202 to make it It is fixed inside the supporting groove 1033, so as to realize the overall fixation of the branch pipe positioning assembly 2. It is convenient and flexible to use. The above method can realize the adjustment and positioning operation of each branch pipe positioning assembly 2. After the adjustment is completed, the reference lines 1011 on the two positioning plates 101 are aligned with the straight lines drawn on the main pipe, and the position of each connecting branch pipe 204 is determined by a marking pen. After the marking is completed, the device is removed, and a hole is opened according to the positioning position using a hole opener. After the hole opening is completed, the pipe body positioning assembly 1 is positioned to the corresponding position again, and the connecting branch pipes 204 are welded one by one. The connecting branch pipe 204 is inserted into the positioning sleeve 201 and guided by the positioning sleeve 201. Since the axis of the positioning sleeve 201 is always perpendicular to the reference line 1011 after assembly, the verticality (horizontality) of the connecting branch pipe 204 after welding with the main pipe is guaranteed, and the construction is standardized.

[0029] In another embodiment, the inner diameter of the positioning sleeve 201 can be replaced according to the specifications of the connecting branch pipe 204, that is, the positioning sleeve 201 can be made into standard parts of different specifications according to the specifications of the connecting branch pipe 204, which is convenient for use in different construction conditions, thereby improving the flexibility and adaptability of the device.
