Description

Technical Field

[0001] The utility model relates to the technical field of pipeline locator installation equipment, in particular to an automatic installation device for underground pipeline locators. Background Art

[0002] An underground pipeline locator is a device used to detect and locate pipelines and facilities buried underground. The underground pipeline locator is directly connected to the surface of the metal pipeline through a connected installation device. When the underground pipeline locator emits electromagnetic signals, these signals will pass through the metal pipeline and interact with the pipeline surface. Since the metal pipeline will generate induced currents to the electromagnetic signals, the locator can detect the signals of these induced currents. By analyzing the characteristics of the induced currents, such as intensity and direction, the locator can determine the position, depth and direction of the metal pipeline.

[0003] In the prior art, such as Figure 1 As shown, pure copper clamps are mostly used to connect with the transmitter, and the operator manually clamps the clamps on the metal flange of the underground pipeline, which has low work efficiency. In addition, compared with pipelines buried deeper than the ground, they need to be installed in deep wells, and operators may face the risk of falling. Especially when working in narrow spaces, there may be insufficient oxygen in the deep well, and toxic gases such as hydrogen sulfide accumulate, posing a risk of suffocation. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Combination Figures 2 to 4An automatic installation device for an underground pipeline locator shown in the figure includes a mounting frame body 1, and a first magnet 7 is slidably connected inside the mounting frame body 1. The first magnet 7 is used to magnetically attract the underground metal pipe or metal flange, so that the entire installation device is fixed on the metal pipe or metal flange. The first connecting frame 3 and the second connecting frame 4 are symmetrically arranged on both sides of the mounting frame body 1. After the first magnet 7 is magnetically attracted to the metal pipe, the first connecting frame 3 and the second connecting frame 4 are pivoted relative to the mounting frame body 1 at the same time, and the pivot planes of the first connecting frame 3 and the second connecting frame 4 are parallel to the moving plane of the first magnet 7, that is, when the first magnet 7 moves to be in contact with the outer wall of the metal pipe, the first connecting frame 3 and the second connecting frame 4 symmetrical about the first magnet 7 rotate at the same time until they are in contact with the outer wall of the metal pipe.

[0028] On the pivot plane of the first connecting frame 3 and the second connecting frame 4, the second magnet 10 and the third magnet 11 are slidably connected to the first connecting frame 3, and the second connecting frame 4 is provided with a conductive probe 12, that is, the second connecting frame 4 rotates to make the second magnet 10 and the third magnet 11 magnetically attracted to the metal pipe wall, and the second connecting frame 4 rotates with the second connecting frame 4 at the same time. When the second magnet 10 and the third magnet 11 are in contact with the metal pipe wall, the conductive probe 12 is also in contact with the metal pipe wall. It should be noted that the size of the first connecting frame 3 is the same as the size of the second connecting frame 4. Regarding the position of the conductive probe 12, it is necessary to ensure that when the second magnet 10 and the third magnet 11 are in contact with the outer wall of the pipe, the conductive probe 12 is also in contact with the outer wall of the pipe.

[0029] In the above structure, if Figure 2 As shown, the mounting frame body 1 is connected with a wire, wherein the wire connects the transmitter of the pipeline locator and the conductive probe 12. When the conductive probe 12 is attached to the metal pipeline and the transmitter of the pipeline locator works, a signal is transmitted to the underground metal pipeline through the conductive probe 12.

[0030] Specifically, Figure 3 and Figure 4 As shown, a gear 16 is rotatably arranged inside the mounting frame body 1, and incomplete gears 17 are respectively arranged at the ends of the first connecting frame 3 and the second connecting frame 4 to mesh with the gear 16. Through the transmission of the gear 16, the meshing between the gear 16 of the mounting frame body 1 and the incomplete gear 17 on the connecting frame can realize force transmission and rotation. This design can ensure the synchronous rotation of the first connecting frame 3 and the second connecting frame 4, so that the entire mounting device can be effectively fixed on the metal pipe to maintain a stable position and contact.

[0031] Regarding how to control the rotation start and stop of the first connecting frame 3 and the second connecting frame 4, in some embodiments, as Figure 2 and Figure 3As shown, the mounting frame body 1 is connected to a first limiting frame 2, and the first connecting frame 3 and the second connecting frame 4 are symmetrical relative to the first limiting frame 2, the first magnet 7 is slidably connected in the first limiting frame 2, a retractable first connecting column 8 is provided in the first limiting frame 2, a first spring 9 is connected to the outer sleeve of the first connecting column 8, the first magnet 7 is respectively connected to the first spring 9 and one end of the first connecting column 8, when the first magnet 7 is not in magnetic contact with the metal tube wall, the first magnet 7 is located inside the first limiting frame 2 under the pulling force of the first spring 9, and is at a certain distance from the bottom of the limiting frame.

[0032] A conductive sheet 14 is provided inside the first limit frame 2 at one end away from the first spring 9, that is, a conductive sheet 14 is fixed inside the first limit frame 2 within a certain distance from the bottom of the first magnet 7 to the limit frame, and a limiting groove is provided on the inner wall of the first limit frame 2 near the conductive sheet 14, in which a conductive block 13 adapted to the conductive sheet 14 is slidably connected, and a compression spring 15 is provided between the conductive block 13 and the inner wall of the first limit frame 2, and the moving direction of the conductive block 13 is perpendicular to the moving direction of the first magnet 7, that is, when the first magnet 7 is magnetically attracted to contact with the metal tube wall, the first magnet 7 moves to the bottom of the limit frame in the first limit frame 2, and in this process, it will contact with the conductive block 13, thereby pushing the conductive block 13 to contact with the conductive sheet 14. The purpose of this design is to ensure that when the first magnet 7 contacts with the metal tube wall, the conductive block 13 can be pushed to contact with the conductive sheet 14 through contact with the first magnet 7 to establish an electrical connection.

[0033] On the basis of the above, the gear 16 is driven by a motor, and the conductive sheet 14 is electrically connected to the motor. More specifically, the contact between the conductive block 13 and the conductive sheet 14 establishes an electrical connection, so that the motor can be electrically connected to the connected circuit through the conductive sheet 14. After the motor is started, it starts to rotate. Due to the contact between the conductive block 13 and the conductive sheet 14, the motor can obtain current and rotate, and the gear 16 driven by the motor starts to rotate, and the power is transmitted to the first connecting frame 3 and the second connecting frame 4 by the way of the engagement of the incomplete gear 17 with the gear 16, so that they start to rotate synchronously.

[0034] Among them, in some embodiments, in order to reduce the contact friction between the conductive block 13 and the first magnet 7 and make the movement between them smoother, the inclination angle of the conductive block 13 is adjusted, that is, the conductive block 13 is expanded and inclined toward the bottom of the first limit frame 2 (away from the first spring 9), thereby reducing the contact friction and allowing the conductive block 13 to move more easily when in contact with the first magnet 7.

[0035] When the first magnet 7 is continuously magnetically attracted to the metal pipe wall, the conductive block 13 is continuously in contact with the conductive sheet 14 due to the thrust of the first magnet 7; when the entire installation device is removed from the metal pipe or the metal flange, the first magnet 7 moves to the inside of the first limit frame 2 under the pulling force of the first spring 9, that is, it is reset to a position where it is not in contact with the conductive block 13. At this time, the conductive block 13 is reset under the elastic force of the compression spring 15.

[0036] Regarding how to control the first connecting frame 3 and the second connecting frame 4 to stop rotating, in some embodiments, as Figures 2 to 4 As shown, on the side of the first limiting frame 2 relative to the mounting frame body 1, a second limiting frame 5 is arranged on the first connecting frame 3, a third limiting frame 6 is arranged on the second connecting frame 4, and the second limiting frame 5 and the third limiting frame 6 are symmetrical with respect to the first limiting frame 2, a retractable second connecting column and a third connecting column are arranged in the second limiting frame 5, and the second connecting column and the third connecting column are parallel to each other, a second spring is connected to the outer sleeve of the second connecting column, and a third spring is connected to the outer sleeve of the third connecting column, the second magnet 10 is fixedly connected to the second spring and one end of the second connecting column, the third magnet 11 is fixedly connected to the third spring and one end of the third connecting column, and a conductive probe 12 is arranged at one end of the third limiting frame 6.

[0037] On the basis of the above structure, a distance sensor 18 is provided at one end of the second magnet 10 and / or the third magnet 11, specifically an Omron E3T series infrared sensor, which is suitable for detecting the position and distance of a close object. The distance sensor 18 is electrically connected to the motor. When the distance sensor 18 detects that the contact distance is less than a set value, the motor that controls the gear 16 to rotate will stop; Figure 4 As shown, a distance sensor 18 is provided on the second magnet 10. When the distance sensor 18 detects that the contact distance with the metal tube wall is less than a set value, such as the distance with the metal tube wall is less than 1 mm, the motor for controlling the rotation of the gear 16 stops. This means that the second magnet 10 and the third magnet 11 are in magnetic contact with the metal tube wall, and the conductive probe 12 is in contact with the metal tube wall, indicating that the rotation of the first connecting frame 3 and the second connecting frame 4 needs to be stopped to avoid further contact or damage.

[0038] During specific use, the automatic installation device connected to the pipeline locator transmitter is lowered to the underground metal pipeline until the first magnet 7 in the automatic installation device is magnetically in contact with the pipe wall of the metal pipe. When the first magnet 7 is magnetically in contact with the metal pipe wall, the conductive block 13 is in contact with the conductive sheet 14 to establish an electrical connection, the motor is started, and the driven gear 16 starts to rotate. The first connecting frame 3 and the second connecting frame 4 start to rotate synchronously until the second magnet 10 and the third magnet 11 are magnetically in contact with the metal pipe wall and the conductive probe 12 is in contact with the metal pipe wall. At this time, the distance sensor 18 detects that the contact distance is less than the set value, and the motor that controls the rotation of the gear 16 stops. Then, the pipeline locator transmitter is started to start the positioning operation of the underground pipeline.

All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
