Problems solved by technology

If threaded connection is used, it will not only cause torsion and unreliable connection of the cables between the gear train and the electronic cabin, but also the risk of disassembly by mistake. At the same time, the degree of rotation is greatly affected by human influence during actual operation, which will speed up the threaded connection. fail
If the hoop connection is used, the diameter of the main body will be increased, which greatly increases the risk of the instrument being stuck in the pipeline

Embodiment 1

[0043] like figure 1 As shown, a plug-in inertial locator for underground pipelines includes an electronic cabin 1 and a centering wheel train 2 docked at both ends of the electronic cabin 1. When the two are docked, radial locking elements can be used to lock them.

[0044] combine figure 2 , the centering wheel train 2 includes the shaft end cover shaft 23, the lower disc 21 of the shaft end cover, the upper disc 22 of the shaft end cover, the tension spring 25 and the wheel train unit 24, the bottom end of the shaft end cover shaft 23 and the shaft end The disc 21 under the cover is fixedly connected, the shaft end cover shaft 23 passes through the upper disc 22 of the shaft end cover, and the upper disc 22 of the shaft end cover can slide back and forth along the axial direction of the shaft end cover shaft 23; the tension spring 25 is located at Between the lower disc 21 of the shaft end cover and the upper disc 22 of the shaft end cover, and the two ends of the tension...

Embodiment 2

[0059] combine Figure 8 , the radial locking member can be the locking bolt 8, the disc 21 under the shaft end cover and the electronic cabin 1 are also inserted through the docking step 213 and the docking groove, and the side wall of the docking groove is provided with the locking bolt 8. hole, when the two need to be locked, the locking bolt 8 passes through the hole on the side wall of the docking groove and is threadedly connected with the docking step 213.

Embodiment 3

[0061] combine Figure 9 and Figure 10 The electronic cabin 1 includes a cabin body and a shaft end cover 6 that is detachably and fixedly connected to the end of the cabin body. One end of the shaft end cover 6 is screwed to the cabin body, and the other end is configured as an outer hexagon, and its outer surface is hexagonal. At the same time, the docking groove can be located at the end far away from the cabin body, and the docking step 213 on the disc 21 under the shaft end cover is docked with the docking groove, and then locked by the radial locking member. Certainly, the shaft end cover 6 may also be threadedly connected to the lower disk 21 of the shaft end cover.

Abstract

The invention discloses an inserting type underground pipeline inertial locator. The inserting type underground pipeline inertial locator is characterized in that the inserting type underground pipeline inertial locator comprises an electronic cabin and centering wheel trains abutted at two ends of the electronic cabin, a first abutting end is formed at one end of each centering wheel train, a second abutting end in inserting cooperation with the first abutting end is formed at the end of the electronic cabin, and at least one radial locking part for locking the first abutting end and the second abutting end which are in inserting connection is arranged between the first abutting end and the second abutting end. The inserting type underground pipeline inertial locator has the advantages that the electronic cabin and support wheel trains can be quickly and conveniently mounted, the problem of cable torsion caused in the mounting process of the instrument is avoided, the connection reliability of cables is enhanced, the diameter of the electronic cabin is not increased, and the passing capacity of the instrument in a pipeline is improved.

Description

technical field [0001] The invention relates to a pipeline measurement technology, in particular to a plug-in type inertial locator for underground pipelines. Background technique [0002] With the modernization and development of the city, the underground pipeline network system is increasingly developed, and various pipelines such as electricity, gas, water supply and drainage, rainwater and sewage are intertwined, densely covered with cobwebs, and intricate. In order to conduct professional management and maintenance of the completed underground pipelines, it is necessary to accurately locate the underground pipelines. The underground pipeline inertial locator is a high-precision instrument for precise positioning of underground pipelines. The underground pipeline inertial locator combines gyroscope directional inertial navigation, computer three-dimensional calculation and other technologies. The underground pipeline inertial locator drags the inertial gyro locator thro...
