Description

Technical Field

[0001] The utility model relates to the technical field of pipeline positioning equipment, in particular to an underground pipeline positioning device. Background Technique

[0002] The underground pipeline detection and positioning instrument can quickly and accurately detect the positions, directions, depths of underground water pipes, metal pipes, cables, etc., and the positions and sizes of the damaged points of the anti-corrosion layer of steel pipes without damaging the ground covering soil. It is one of the essential instruments for water supply companies, gas companies, railway communications, industrial and mining enterprises, and infrastructure units to transform, repair, and conduct general surveys of underground pipelines.

[0003] For example, in the utility model patent with the publication number of CN212647032U, an underground pipeline measurement and detection positioning instrument device is disclosed. After determining the position of the pipeline through the underground pipeline detection and positioning instrument body, the air cylinder drives the push-pull rod to move downward to insert the marking rod into the ground, so as to mark and position the position of the pipeline.

[0004] However, when this utility model is in use, the part of the marking rod inserted into the ground is likely to be short, resulting in the marking rod being prone to tipping. In addition, the positioning rod is arranged between the inner wall of the clamping plate and the positioning box, and the positioning rod is limited by the friction force between the clamping spring and the positioning box. Inevitably, there will be shaking and vibration when the whole device is moving, which is likely to cause the positioning rod to fall out of the rod outlet hole, thereby affecting the convenience of use.

The top of the second box body 17 is open and the cross-section of the box body is rectangular. The top of the first box body 13 is open and the cross-section of the box body is circular. The second box body 17 is arranged above the first box body 13 and a second through hole 16 is opened at the bottom of the box body at a position away from the discharge pipe 10.

[0019] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] In the present utility model, the underground pipeline detection and positioning instrument body 2, the first motor 4, the second motor 7 and the third motor 11 are all connected to an external electronic control system through wires. The above devices and connection methods are all prior arts and will not be elaborated here.

[0021] According to the attached Figure 1-2 As can be seen from the specification appendix, when the present utility model is in use, the underground pipeline detection and positioning instrument body 2 is started, and the device is pushed to detect and position the underground pipeline. After determining the position of the pipeline, the position of the bottom plate 1 is adjusted so that the spiral drill bit 8 is located above the position to be marked. The first motor 4 provided at the top of the column 3 is started, and the output end of the first motor 4 drives the connected threaded rod 5 to rotate. The threaded rod 5 drives the slidable block 6 connected by thread to move vertically downward in the chute 3-1 opened on the column 3. Thus, the slidable block 6 drives the connected second motor 7 to move vertically downward. The second motor 7 is started, and the output end of the second motor 7 drives the connected spiral drill bit 8 to rotate. The spiral drill bit 8 penetrates through the first through hole 9 opened on the bottom plate 1, and thus a pit hole is drilled at the marked position. After the drilling is completed, the first motor 4 drives the spiral drill bit 8 to reset its position, and the operations of the first motor 4 and the second motor 7 are stopped. The position of the bottom plate 1 is adjusted so that the discharge pipe 10 is located above the pit hole. The third motor 11 provided on the stepped groove is started, and the third motor 11 drives the connected rotating rod 14 to rotate. The rotating rod 14 drives the pair of turntables 15 connected thereto to rotate. When the pair of turntables 15 rotate, they drive a plurality of positioning rods 18 provided between the arc-shaped groove 15-1 and the inner wall of the first box body 13 to rotate. When one of the positioning rods 18 rotates above the discharge pipe 10, the positioning rod 18 falls into the drilled pit hole through the discharge pipe 10. The operator pushes away the bottom plate 1 and appropriately compacts and consolidates the soil around the positioning rod 18. In the present utility model, the positioning rod 18 is inserted into the pit hole drilled by the spiral drill bit 8, and then part of the soil is backfilled to reinforce the positioning rod 18, which can ensure the burial depth of the positioning rod 18 and effectively prevent the positioning rod 18 from tipping over. When the positioning rod 18 is located in the first box body 13, its position is staggered from that of the discharge pipe 10 to prevent the positioning rod 18 from falling out of the discharge pipe 10 during movement.

[0022] There is a possible implementation. A plurality of positioning rods 18 are vertically arranged between the top plate 20 and the inner wall of the second box body 17. When the third motor 11 drives a pair of turntables 15 to rotate, the pair of turntables 15 drives the plurality of positioning rods 18 between the arc-shaped grooves 15-1 formed thereon and the inner wall of the first box body 13 to rotate. When the positioning rod 18 in a certain pair of arc-shaped grooves 15-1 in the same vertical direction falls out of the discharge pipe 10, when this pair of arc-shaped grooves 15-1 rotates to below the second through hole 16 again, the positioning rod 18 on the side far from the top plate 20 drops downward from the second through hole 16 into this pair of arc-shaped grooves 15-1 to realize feeding the vacant position of the arc-shaped grooves 15-1. After the rightmost positioning rod 18 falls out, under the elastic force of the compression spring 19, the remaining positioning rods 18 in the first box body 13 will move to the right. The top of the positioning rods 18 in the first box body 13 is at the same height as the top of the upper turntable 15, which can ensure that the positioning rod 18 on the side far from the top plate 20 does not jam with the lower rotating part.

[0023] There is a possible implementation. A support rod 12 is arranged on the stepped groove, and the top of the support rod 12 is connected to the bottom of the first box body 13. The support rod 12 supports the bottom of the first box body 13 far from the discharge pipe 10.

[0024] There is a possible implementation. A support seat 21 is arranged on one side of the bottom plate 1 close to the underground pipeline detection and positioning instrument body 2, and a dashboard 22 is arranged on the top of the support seat 21. The first motor 4, the second motor 7 and the third motor 11 are controlled through the dashboard 22.

[0025] There is a possible implementation. A handle 23 is arranged on one side of the bottom plate 1 close to the underground pipeline detection and positioning instrument body 2. When moving the bottom plate 1, the handle 23 is pushed to facilitate the operation.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
