AI Technical Summary
In existing direct-buried pipe docking devices, dirt forms an isolation layer on the surface of the clamping parts and the direct-buried pipe, causing the clamping parts to be unable to fit directly. Under the action of docking thrust/pull force, the direct-buried pipe slides, resulting in gaps or misalignment, and cannot be accurately aligned.
The cleaning and dirt-breaking components are driven by hydraulic push rods. High-pressure gas is supplied by an air pump, and dirt is removed by an annular air distribution pipe and a dust blower. Hard dirt is scraped off by a conical cylinder. The cleaned dirt is collected by a detachable collection frame to ensure the pipe opening is clean. The clamping block is stably clamped by a threaded connection and a support block to achieve precise docking.
It effectively removes dirt and grime from the surface of buried pipes, ensuring that the clamps fit tightly against the pipes, preventing slippage, achieving precise alignment of the docking ends, and improving docking efficiency and connection strength.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of matching device technology, and in particular to a rapid matching device for direct-buried pipes. Background Technology
[0002] Direct burial, also known as trenchless installation, is a method of laying pipes directly in the soil, with the outer surface of the pipe's insulation structure in direct contact with the soil. In hot water heating networks, the most common form of direct burial is to tightly bond the pipe, insulation layer, and protective shell together to form an integrated prefabricated insulated pipe.
[0003] An existing authorized publication number CN209557840U describes a docking device for directly buried insulated pipes, comprising a docking pipe, an insulated pipe, and connectors. Fixing blocks are welded to the upper and lower ends of the outer wall of the insulated pipe. A fixing ring is welded to the middle of the inner wall of the docking pipe. Fixing plates are fixed to the upper and lower ends of the outer wall of the docking pipe via connectors. A vertical plate is welded to the inner side of the fixing plate. A through hole is provided on the left side of the vertical plate. A crossbar is slidably installed on the inner wall of the through hole. A top ring is welded to the inner end of the crossbar. A spring is sleeved on the side wall of the crossbar. This invention, by providing a fixing ring on the inner wall of the docking pipe, a fixing plate on the outer wall of the docking pipe, and a spring-controlled top ring on the inner side of the fixing plate, allows the end of the insulated pipe to abut against the fixing block on the side wall of the insulated pipe, thus fixing the insulated pipe. The structure is simple, making the assembly and disassembly of the insulated pipe and docking pipe more convenient, and the design is reasonable.
[0004] Regarding the aforementioned technologies, the existing docking devices have the following drawbacks: before docking, the pipe end face is contaminated with soil and dirt after clamping. This causes the dirt to form an "isolation layer" between the clamping device and the surface of the buried pipe when the clamping device clamps the buried pipe. The clamping device cannot directly adhere to the surface of the buried pipe. After clamping, the buried pipe slides relative to the other end face under the action of the docking thrust / pull force. The slippage of the buried pipe causes the docking end face to be unable to be accurately aligned, resulting in gaps or misalignment. Therefore, this utility model provides a quick docking device for buried pipes. Utility Model Content
[0005] The purpose of this application is to provide a quick-connection device for direct-buried pipes to solve the problem mentioned in the background art where dirt forms an "isolation layer" between the clamping member and the surface of the direct-buried pipe, the clamping member cannot directly adhere to the surface of the direct-buried pipe, and the direct-buried pipe slides relative to each other under the action of the docking thrust / pull force after clamping. The slippage of the direct-buried pipe causes the docking end faces to be unable to be accurately aligned, resulting in gaps or misalignments.

[0011] Preferably, a torsion block is fixedly connected to one end of the screw, and a nut is threadedly connected to the outer side of the screw.
[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, the hard or clump-like dirt adhering to the outside of the buried pipe is pre-crushed by the combination of the cleaning component and the dirt crushing component, which facilitates the subsequent cleaning of the buried pipe and avoids the dirt affecting the sealing performance and connection strength of the joint.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] Example 1: Reference Figure 1-4The present application describes a quick-connection device for direct-buried pipes. It is equipped with a controller and a power supply. The controller is used to control electrical components (such as telescopic hydraulic cylinders), and the power supply is used to provide power. It is also equipped with an oil supply mechanism for the hydraulic cylinders, which is prior art and will not be described in detail here.The device includes a hydraulic push rod 1, which serves as the power core of the unit, providing stable and controllable thrust and pull. By precisely adjusting the extension and retraction of the output end, it enables fine-tuning of the position and tight connection during direct-buried pipe alignment, effectively improving alignment efficiency. Mounting brackets 2 are fixedly connected to the bottom and output ends of the hydraulic push rod 1, respectively. Mounting brackets 2 act as overall support and a mounting carrier for components, providing a stable mounting foundation for the hydraulic push rod 1 and ensuring reliable connection between auxiliary components such as the cleaning assembly and the main structure, guaranteeing structural stability during device operation. A cleaning assembly is installed on the outer side of the mounting brackets 2. This assembly is used to clean dirt from the direct-buried pipe, preventing dirt from affecting the alignment seal and connection strength. The cleaning assembly includes a pneumatic valve located on the outer side of the mounting brackets 2. Pump 4 provides a high-pressure air source for the cleaning process, serving as a power source for dust blowing and ensuring sufficient air pressure to remove dirt from the target area. An air pipe 16 is fixedly connected to the output end of pump 4, acting as an air supply pipe to stably deliver the high-pressure gas generated by pump 4 to the annular air distribution pipe 6. The annular air distribution pipe 6 is fixedly connected to one end of the air pipe 16, which evenly distributes the high-pressure gas delivered by the air pipe 16 to each dust blowing head 11, ensuring uniform cleaning in the circumferential direction of the pipe opening. The annular air distribution pipe 6 is connected to the mounting bracket 2 via a fixing frame, which rigidly fixes the annular air distribution pipe 6 to the mounting bracket 2, preventing displacement of the annular air distribution pipe 6 during dust blowing and ensuring that the dust blowing head 11 is aligned with the cleaning area. The inner wall of the annular air distribution pipe 6... Multiple interconnected dust blowing heads 11 are fixedly connected to the side. The dust blowing heads 11 concentrate the high-pressure gas distributed by the annular air distribution pipe 6 and spray it directly onto the dirt at the joint of the buried pipe, achieving efficient removal of dirt. A dirt breaking component is provided on the outside of the annular air distribution pipe 6. The dirt breaking component is used to pre-break the hard or clump dirt attached to the outside of the buried pipe, making it easier for the dust blowing heads 11 to clean it thoroughly. The dirt breaking component includes a conical cylinder 7 fixedly connected to the outside of the annular air distribution pipe 6. The conical cylinder 7 adopts a conical structure, which makes it easy for the device to extend into the pipe opening. At the same time, its conical surface can initially scrape off the floating dust at the edge of the pipe opening and guide the dirt to collect towards the discharge port 19. A cleaning ring 8 is fixedly connected to the outside of the conical cylinder 7. The surface of the cleaning ring 8 can be provided with wear-resistant cleaning teeth. When the device extends into or retracts from the pipe opening, it scrapes and breaks up the hard dirt on the inner wall of the pipe opening, improving the thoroughness of dirt cleaning; a material leakage port 19 is provided on the outer side of the conical cylinder 7, which is used to discharge large pieces of dirt after the cleaning ring 8 is broken, so as to prevent dirt from accumulating in the conical cylinder 7 and affecting the crushing and cleaning effect; a connecting block 9 is fixedly connected to the outer side of the annular air distribution pipe 6, which serves as the installation connector of the collection frame 10, realizing a stable connection between the collection frame 10 and the annular air distribution pipe 6; the collection frame 10 is detachably connected to the outer side of the connecting block 9, which is used to receive the broken dirt discharged from the material leakage port 19 and some dirt blown off by the dust blown head 11, preventing dirt from scattering into the construction environment. At the same time, the detachable design facilitates subsequent dirt dumping and cleaning of the collection frame 10.
[0019] Example 2: Reference Figure 1-4 Based on the same concept as Embodiment 1 above, this embodiment further proposes that support rings 5 are fixedly connected to the outer side of the mounting bracket 2. The support rings 5 are used to provide a stable installation reference, enhance the connection rigidity of the fixing rods 20, and prevent deformation under force. A pair of fixing rods 20 are fixedly connected to the outer side of the support rings 5. The fixing rods 20 play the role of transmitting support force and positioning the lower clamping block 12, ensuring the relative positional accuracy of the lower clamping block 12 and the upper clamping block 3. The lower clamping block 12 is fixedly connected to one end of the fixing rod 20. The lower clamping block 12 and the upper clamping block 3 cooperate to clamp and fix the target buried pipe. The upper clamping block 3 is fixedly connected to the outer side of the mounting bracket 2. The upper clamping block 3 provides upper clamping support and forms a clamping closed loop with the lower clamping block 12 to ensure the stability of the buried pipe clamping. The inner side of the lower clamping block 12 is provided with a groove 18, which is a support block. 13 provides installation space and sliding guidance, restricting the movement trajectory of the support block 13. The inner side of the lower clamping block 12 is threaded with a screw 15. The screw 15 realizes the linear displacement adjustment of the support block 13 through threaded transmission. The support block 13 is set in the groove 18. The support block 13 directly contacts the buried pipe, increasing the clamping contact area, reducing local pressure, and avoiding damage to the buried pipe. The screw 15 is rotatably connected to the support block 13, ensuring that the support block 13 only makes linear movement when the screw 15 rotates, without following the rotation. One end of the screw 15 is fixedly connected to a torsion block 14. The torsion block 14 increases the operating torque, making it easier to drive the screw 15 to rotate manually or with tools, improving the convenience of adjustment. The outer side of the screw 15 is threaded with a nut 17. The nut 17 is used to lock the position of the screw 15, preventing the screw 15 from loosening due to vibration after clamping, and ensuring the stability of the clamping state.
[0020] The working principle of this utility model is as follows: Two sections of buried pipe are respectively fitted onto the support ring 5. The conical cylinder 7 and the cleaning ring 8 are used to initially break up and clean the dirt on the outside of the buried pipe. The dust and debris slide along the conical cylinder 7 through the leakage port 19 into the collection frame 10. The air pump 4 is controlled to clean the outside of the buried pipe through the air pipe 16, the annular air distribution pipe 6, and multiple dust blowing heads 11 to prevent the dust and debris adhering to the outside of the buried pipe from affecting the subsequent clamping of the buried pipe. The buried pipe is placed between the corresponding upper clamping block 3 and lower clamping block 12. The torsion block 14 is dragged to drive the screw 15 to rotate. The buried pipe is supported and fixed by the support block 13, and the screw 15 is limited and fixed by the nut 17.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
