Description

Technical Field

[0001] This utility model relates to the field of acoustic tube sealing test technology, and more specifically, to a sealing joint for connecting acoustic tubes. Background Technology

[0002] In the construction industry, sonic logging pipes are an indispensable tool for testing the integrity of cast-in-place piles, and their sealing performance is crucial to ensuring the accuracy of the test results. During the sealing test of sonic logging pipes, the sealing joint plays a vital role.

[0003] The current sealing structure design of the sonic logging pipe sealing joint is not ideal. Specifically, the sealing components are connected to both ends of the sonic logging pipe by bolts, and one of the sealing components is connected to the water pressure resistance testing equipment. Water is then injected into the sonic logging pipe to test the sealing effect. However, after the sealing components on both sides are installed, there is a lack of inner extrusion force along the axial direction of the sonic logging pipe, so the sealing effect needs to be improved.

[0004] At the same time, the existing sealing joints are not versatile enough, and are only suitable for sonic logging pipes of a specific size, which cannot meet the sealing test requirements of sonic logging pipes of diverse specifications in different projects.

[0005] In summary, the current sealing joints for sonic logging pipes have the aforementioned problems that urgently need to be addressed. Utility Model Content

[0006] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a sealing joint for connecting acoustic logging pipes.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A sealing joint for connecting a sonic logging pipe includes a sonic logging pipe body and a water pressure resistance testing device, and also includes an upper mounting block, a lower mounting block, a wedge block, a column, a through hole, a flow hole, an internal pressure connection assembly, a mounting cylinder, a wedge groove, and an adjustable sealing assembly.

[0009] The wedge blocks are welded onto the upper mounting block and the lower mounting block respectively, and the upper mounting block and the lower mounting block are welded to the opposite side of the wedge blocks. The column on the upper mounting block has a through hole with internal thread to connect the water pressure testing equipment.

[0010] The flow hole is located on the wedge block and has the same diameter as the through hole and is connected to it.

[0011] The upper mounting block and the lower mounting block are connected by an internal pressure connection assembly;

[0012] The wedge-shaped groove that mates with the wedge block is formed inside the mounting cylinder;

[0013] An adjustable sealing assembly is installed inside the mounting cylinder to provide a tight seal between the acoustic tube body and the wedge block.

[0014] Furthermore, the internal pressure connection assembly includes a through hole, a long threaded rod, and a nut.

[0015] Several perforations are respectively made on the upper mounting block and the lower mounting block, and they correspond one to one;

[0016] The long screw passes through two holes that are directly opposite each other on the upper and lower mounting blocks, and the long screw corresponds to and engages with multiple sets of directly opposite holes.

[0017] The nut is threaded into the long screw.

[0018] Furthermore, the adjustable sealing assembly includes bolts, a steel strip, and a rubber ring.

[0019] Several threaded holes are circumferentially formed on the mounting cylinder and connect to the interior of the mounting cylinder;

[0020] The bolts pass through the threaded holes, and the two holes correspond one-to-one.

[0021] A multi-coiled steel strip is placed inside the mounting cylinder, with the outer side of the steel strip mating with one end of the bolt, and a rubber ring is provided on the inner side of the steel strip.

[0022] Furthermore, the mounting cylinder has multiple rows of threaded holes on its circumference.

[0023] Furthermore, a sealing ring is provided on the end face of the mounting cylinder that mates with the wedge block.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] Compared with existing technologies, this application can not only install seals at both ends of the sonic logging pipe body, but also apply internal pressure along the axial direction of the sonic logging pipe to further improve the sealing effect.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0032] like Figures 1 to 3 As shown, a sealing joint for connecting a sonic logging pipe includes a sonic logging pipe body 1 and a water pressure testing device 101, as well as an upper mounting block 2, a lower mounting block 3, a wedge block 4, a column 5, a through hole 51, a flow hole, an internal pressure connection assembly 6, a mounting cylinder 7, a wedge groove, and an adjustable sealing assembly 8.

[0033] The wedge block 4 is welded to the upper mounting block 2 and the lower mounting block 3 respectively, and the upper mounting block 2 and the lower mounting block 3 are welded to the other side of the wedge block 4. The column 5 on the upper mounting block 2 is provided with a through hole 51 with internal thread to connect the water pressure resistance testing equipment 101.

[0034] The flow hole is opened on the wedge block 4 and the flow hole has the same diameter as the through hole 51 and is connected (the flow hole is not shown in the figure).

[0035] The upper mounting block 2 and the lower mounting block 3 are connected by the internal pressure connection assembly 6;

[0036] A wedge groove that mates with the wedge block 4 is formed inside the mounting cylinder 7 to accurately define the installation position of the mounting cylinder 7, thereby making the flow hole and the through hole 51 on the same straight line (the wedge groove is not shown in the figure).

[0037] The adjustable sealing assembly 8 is installed inside the mounting cylinder 7 to provide a tight seal between the acoustic tube body 1 and the wedge block 4.

[0038] Specific implementation of the embodiments of this utility model, such as Figure 1 As shown, the internal pressure connection assembly 6 includes a through hole, a long screw 61, and a nut 62.

[0039] Several perforations are respectively made on the upper mounting block 2 and the lower mounting block 3 and correspond one to one (the perforations are not shown in the figure).

[0040] The long screw 61 passes through two holes that are directly opposite each other on the upper mounting block 2 and the lower mounting block 3, and the long screw 61 corresponds to and cooperates with multiple sets of directly opposite holes.

[0041] Nut 62 is threaded into long screw 61.

[0042] Specific implementation of the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the adjustable sealing assembly 8 includes a bolt 81, a steel strip 82, and a rubber ring 83.

[0043] Several threaded holes 71 are circumferentially formed on the mounting cylinder 7 and connect to the interior of the mounting cylinder 7 (specifically, two rows of threaded holes 71 are circumferentially formed on the mounting cylinder 7).

[0044] Bolt 81 passes through threaded hole 71 and the two correspond one-to-one;

[0045] A multi-coiled steel strip 82 is placed inside the mounting cylinder 7, with the outer side of the steel strip 82 engaging with one end of the bolt 81. A rubber ring 83 is provided on the inner side of the steel strip 82 (after placement, the outer wall of the steel strip 82 can contact the inner wall of the mounting cylinder 7 to prevent it from falling off).

[0046] To further improve the sealing performance after the mounting cylinder 7 and the wedge block 4 are mated, the above embodiment is further optimized by providing a sealing ring (not shown in the figure) on the end face of the mounting cylinder 7 that mates with the wedge block 4.

[0047] The working process of this utility model:

[0048] Before performing the sealing test of the sonic logging tube, the wedge groove inside the mounting cylinder 7 is first matched with the wedge block 4, and then a mounting cylinder 7 is installed on the upper mounting block 2 and the lower mounting block 3 respectively. Then, the two ends of the sonic logging tube body 1 are respectively passed through the two mounting cylinders 7 and connected to the end faces of the two wedge blocks 4. Then, the sonic logging tube body 1 is pressed into the area between the upper mounting block 2 and the lower mounting block 3 by multiple long screws 61 and nuts 62. This not only achieves the sealing of the two ends of the sonic logging tube body 1, but also applies internal pressure along the axial direction of the sonic logging tube to further improve the sealing performance. After the mounting cylinder 7 is installed, its contact position with the upper mounting block 2 and the lower mounting block 3 can also be sealed by sealing rings.

[0049] Then, by sequentially operating multiple bolts 81 along the circumference of the mounting cylinder 7, the rubber ring 83 can be pressed and sealed against the joint area between the sonic logging pipe and the wedge block 4. Setting multiple rows of bolts 81 can apply a more uniform and comprehensive force, while the steel strip 82 can change the point contact between the bolts 81 and the rubber ring 83 into a surface contact, thereby effectively extending the service life of the rubber ring 83. In this way, the position of the rubber ring 83 can be adjusted according to the sonic logging pipe of different specifications to effectively seal and meet and adapt to the sealing test requirements of sonic logging pipes of various specifications in different projects. It should be noted that the inner diameter of the mounting cylinder 7 is larger than the diameter of the sonic logging pipe body to meet the installation and sealing requirements of sonic logging pipes of different specifications.

[0050] After the bolts 81 are adjusted in sequence, the water pressure testing device 101 is connected to the water source, allowing water to flow through the through hole 51 and the flow hole into the body of the sonic logging tube 1. Then, it can be observed from the outside whether the sonic logging tube leaks. After completing the sealing test of one sonic logging tube, it is only necessary to release the locking of the nuts 62 at both ends of the long screw 61 to easily complete the disassembly and installation of the next sonic logging tube. After the previous sonic logging tube is disassembled, the position of the steel strip 82 and the rubber ring 83 can be adjusted accordingly (at this time, the bolts 81 can be completely or partially disassembled, but the rubber ring 83 should not be subjected to the squeezing force applied inward) so as not to hinder the installation and sealing of the next sonic logging tube. Then, the above process is repeated to install a new sonic logging tube for a new round of sealing tests.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
