Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage engineering, in particular to a water supply and drainage pipeline positioning device. Background Art

[0002] At present, in view of the problem that drainage pipes need to be positioned before installation, there are positioning devices in the prior art to solve the problem. For example, the authorized patent with application number 202220587433.1 and subject name of a water supply and drainage pipe positioning device for construction projects proposes "adjustable basic positioning is achieved through the first mounting rod on the inner sleeve, and secondly, the second mounting rod is used to supplement and strengthen the positioning effect, so as to achieve the effect of quickly positioning the slave water supply and drainage pipe in the main water supply and drainage pipe as a whole. The threaded column and the bonding plate can be rotated, so that when the threaded column rotates in and out, the bonding plate can always be attached to the surface of the slave water supply and drainage pipe, and the bonding plate will not rotate due to the rotation of the thread. Because the internal space is limited, it will not block the actual thread from rotating. Secondly, the retractable telescopic tube can achieve a multi-point abutment effect to achieve a better positioning effect. A limiter is installed to limit the pop-up effect of the spring. The moving block installed on the arc track is ensured to slide to ensure that the elastic top block on the moving block can effectively support the slave water supply and drainage pipe, so as to ensure that the actual installation fluctuation is small."

[0003] From the analysis of the above-mentioned disclosed technical content, the above-mentioned prior art adopts a structure that can manually output spiral top pressure from both inside and outside to perform positioning operations in order to meet the positioning requirements after the double drainage pipes are assembled. However, in the applicant's actual working experience, if the above-mentioned device is used, the workload of the staff's manual work will increase, because the positioning of the inner and outer drainage pipes needs to be operated one by one. Secondly, the drainage pipes used in actual construction are of uniform specifications and are used in large quantities.

[0032] The positioning device is formed by the double-ring bracket 3 and the structure set by the double-ring bracket 3, and the first positioning rod 4 and the second positioning rod 5 inside the positioning device are not less than two. When the outer drainage pipe 1 and the inner drainage pipe 2 are assembled and installed and need to be positioned, the positioning device is sleeved inside the outer drainage pipe 1, and then the inner drainage pipe 2 is sleeved on the inner side of the second ring plate 32;

[0033] Hold the composite handle 9 and make the arc-shaped tooth plate inside the composite handle 9 intermittently mesh with the gear on the I-shaped threaded rod 81 for transmission, thereby driving the locking rod 8 to rotate and press the bidirectional composite pressure block 6, so that the bidirectional composite pressure block 6 uses its own two inclined surfaces to synchronously press one end of the first T-shaped rod body 41 and one end of the second T-shaped rod body 51 inside the first positioning rod 4, and the angle between the two inclined surface structures of the bidirectional composite pressure block 6 is set according to the size of the external drainage pipe 1 and the internal drainage pipe 2. Therefore, in the process of pressing and positioning, the bidirectional composite pressure block 6 can be used for a structural pressing operation to make the first positioning rod 4 and the second positioning rod 5 synchronously press and limit the external drainage pipe 1 and the internal drainage pipe 2, and the remaining first positioning rod 4 and the second positioning rod 5 are also operated according to the above steps, thereby completing the concentric multi-point clamping and positioning of the external drainage pipe 1 and the internal drainage pipe 2. Example

[0034] The positioning device is composed of a double-ring bracket 3 and a structure set up by the double-ring bracket 3, and the first positioning rod 4 and the second positioning rod 5 inside the positioning device are not less than two. When the outer drainage pipe 1 and the inner drainage pipe 2 are assembled and positioned, the positioning device is sleeved inside the outer drainage pipe 1, and then the inner drainage pipe 2 is sleeved on the inner side of the second ring plate 32. The composite handle 9 is held and the arc-shaped tooth plate inside the composite handle 9 is intermittently meshed with the gear on the I-shaped threaded rod 81 for transmission, and then the locking rod 8 is driven to rotate and press the bidirectional composite pressure block 6, so that the bidirectional composite pressure block 6 can use its own The two inclined surfaces of the body synchronously press one end of the first T-shaped rod body 41 and one end of the second T-shaped rod body 51 inside the first positioning rod 4, and the angle between the two inclined surface structures of the two-way composite pressing block 6 is set according to the sizes of the external drainage pipe 1 and the internal drainage pipe 2.

The remaining first positioning rods 4 and the second positioning rods 5 are also operated according to the above steps, thereby completing the concentric multi-point clamping and positioning of the external drainage pipe 1 and the internal drainage pipe 2;

[0035] When the sizes of the outer drain pipe 1 and the inner drain pipe 2 change, a matching bidirectional composite pressure block 6 can be set according to the changed sizes of the outer drain pipe 1 and the inner drain pipe 2, and then the screws between the second supporting curved plate 101 and the outer drain pipe 1, and the screws between the old bidirectional composite pressure block 6 and the transition sleeve 82 are screwed, and the old bidirectional composite pressure block 6 and the auxiliary guide component 10 are removed, and then the new bidirectional composite pressure block 6 and the auxiliary guide component 10 are installed in the same manner as the screw locking method, and the positioning device can continue to be used.
