[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. The illustrative implementation methods and descriptions of the embodiments of this disclosure are only used to explain the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0026] like Figure 1 As shown, the water pipe construction and connection device of this application includes main components such as a pipe clamping arm 1, a guide frame 2, an adjusting screw mechanism 3, and a support bracket 4. This device is used to ensure precise alignment and fixation during the construction of water pipes, ensuring the quality of pipe connections and reducing deviations and misalignments.

[0027] The pipe clamping arm 1 is one of the core components of this device. Its function is to effectively clamp and fix the pipe to be installed during the docking process, so as to ensure that the two pipe sections remain in a fixed position during welding or connection and avoid any unnecessary displacement. In order to provide stronger stability, the pipe clamping arm 1 can be equipped with adjustable pressure clamps, so as to flexibly adapt to pipes of various sizes and materials according to specific application scenarios.

[0028] Guide frames 2 are installed on both sides of the pipe clamping arm 1 and are specifically fixed to the support bracket 4. They are responsible for providing precise axial guidance and centerline alignment assistance for the pipe section to be connected. To improve connection accuracy, the guide frames 2 are designed with symmetrically distributed and floating positioning plates. These floating positioning plates 21 can move slightly to a certain extent with the direction of the applied external force, but always maintain the constraint on the middle pipe, ensuring that the two connection points can fit perfectly. In addition, the positioning plates are usually made of wear-resistant materials and equipped with rollers or other forms of friction-reducing devices to reduce the sliding resistance of the pipe, facilitating smooth pipe insertion and positioning.

[0029] The adjusting screw mechanism 3 is connected to the pipe clamping arm 1. More specifically, the adjusting screw mechanism 3 is located at the bottom of the pipe clamping arm 1, aiming to achieve fine-tuning of the pipe clamping degree. The adjusting screw mechanism 3 in this device includes not only a pair of double-helix adjusting screws 31 with completely opposite rotation directions (if one rotates clockwise, the other must rotate counterclockwise), but also a manual rotating wheel 32 equipped with high-precision measuring instruments, such as a highly clear scale, to achieve fine displacement control. This fine adjustment mechanism allows the pipe to be slowly advanced under controlled conditions until accurately aligned, thereby greatly reducing the possibility of misalignment due to operational errors.

[0030] The support bracket 4 is located below the pipe clamping arm 1, primarily to increase structural robustness and adapt to more complex construction environments. The support bracket 4 can be folded or telescopically adjusted in height and horizontal span, allowing the entire device to be placed flat on uneven ground or other irregular surfaces. It may also be equipped with adjustable feet or other forms of anchoring accessories to further ensure safety in situations with high wind speeds or when prolonged work stops are required.

[0031] This water pipe connection device, through the meticulous design and combination of its components, successfully addresses various deviations and misalignments that may occur during pipe connection. First, the pipe clamping arm 1 ensures each pipe section is reliably locked in its designated position, preventing loosening or displacement due to gravity or human disturbance. Second, relying on the precise guiding path provided by the guide frame 2, the pipes can be quickly and accurately guided towards the target connection point. Then, utilizing a double-helix counter-rotating mechanism and high-precision scale markings, the user can very carefully adjust the spacing and parallelism between the two pipes within the necessary range. Finally, the highly stable support bracket provides a solid operating platform foundation before all actions are completed, ensuring the stability and coordination of the overall system. These combined effects significantly improve on-site construction efficiency and guarantee construction quality.

[0032] In one embodiment, further reference Figure 2 The pipe clamping arm 1 of the water pipe construction and docking device of this application includes multiple fixing blocks 5, which are evenly distributed circumferentially on the inner wall of the pipe clamping arm 1. The fixing blocks 5 are radially movable, allowing the device to accommodate pipes of different diameters to be docked and ensuring effective clamping and fixation of the pipes. The pipe clamping arm 1 is designed to securely clamp the pipes to be docked, preventing pipe displacement due to external factors during construction. This function is achieved by the fixing blocks 5 forming a reliable interlocking structure with the inner wall of the pipe clamping arm 1.

[0033] To further enhance adaptability to pipes of different diameters, the fixing blocks 5 can not only move radially but also be adjusted to the appropriate clamping position as needed, ensuring that each pipe segment is reliably and evenly clamped. This is achieved through a high-precision position adjustment mechanism, such as using a fine-tuning screw or other precision mechanical components to control the specific position of the fixing blocks 5. In operation, the user only needs to manually adjust or mechanically move each fixing block 5 a certain distance outward or inward until they can firmly grip the required pipe to be connected without causing any damage to its outer surface. This design makes the device suitable for various pipe installation applications, providing broad compatibility and greater flexibility.

[0034] For example, the pipe clamping arm 1 and the fixing block 5 can be connected via a sliding groove, guide post, or elastic mechanism to ensure that the fixing block 5 can slide smoothly radially without disengaging from the track. Furthermore, a locking device can be introduced to ensure that the adjusted position remains unchanged, maintaining a good clamping effect throughout the entire construction process. This not only meets the needs of practical applications but also improves the safety and stability of the equipment.

[0035] In one embodiment, continue to refer to Figure 2 The fixing block 5 of the water pipe construction and docking device of this application is provided with an elastic sealing gasket 6 on its inner side. This elastic sealing gasket 6 is located inside the fixing block 5 and directly contacts the outer wall of the pipe, ensuring a tight fit between the two under clamping conditions. This prevents mud, water, and debris from the external environment from entering the interface, ensuring the cleanliness and stability of the docking area. This design utilizes the properties of elastic materials and appropriate clamping force to allow the sealing gasket to form an effective barrier on the outer wall of pipes of different shapes and sizes, improving construction quality.

[0036] Specifically, the fixing block 5 is connected to the pipe clamping arm 1, and the opening and closing of the block is controlled by adjusting the screw mechanism 3, thereby achieving stable fixation of the pipe. To achieve optimal sealing, an elastic sealing gasket 6 is installed on the pipe-facing part of the fixing block 5, ensuring even force distribution when the fixing block 5 clamps. This sealing gasket material possesses good elasticity and durability, maintaining excellent sealing performance even under prolonged or repeated use, meeting the needs of complex construction environments.

[0037] For example, a polymer composite material can be used to make the elastic sealing gasket 6, which has a high resilience and weather resistance, making it suitable for on-site construction under various weather conditions. To ensure reliable installation and effective sealing, the shape of the sealing gasket must fit tightly with the inner side of the fixing block 5. It can be fixed in the preset position by pressing or pasting, with an appropriate gap reserved to allow for compression deformation during clamping, thereby ensuring the stability of the sealing effect.

[0038] In one embodiment, further reference Figure 3 and Figure 4 The floating positioning plate 21 of the water pipe construction docking device of this application is equipped with a laser alignment system 7. This system uses laser beam emission and reception to detect and confirm whether the center lines of the end faces of the two pipes to be docked are precisely aligned. To ensure installation accuracy, this key measuring tool is integrated into the floating positioning plate 21. By fixing the laser to the surface of the floating positioning plate 21 and installing the detector in the same position but facing different directions, effective monitoring of the relative position of the pipes can be achieved.

[0039] Floating positioning plates 21 are symmetrically positioned within the guide frame 2, with one set on each side, to ensure the clamped pipe is on the correct path while providing precise alignment. The deviation value is calculated using the time or displacement data between the laser beam's round trip and is fed back to the control system in real time, allowing technicians to make timely corrections based on the deviation prompts and improve the final alignment quality. Specifically, during operation, the monitored positional difference can be gradually reduced until the requirements are met by adjusting the clamping arms and the adjusting screw mechanism 3. This method not only limits the spatial layout of the equipment on the floating positioning plates 21 but also clarifies the collaborative working method between the laser and the receiver and their information transmission path.

[0040] In one embodiment, the combination of the floating positioning plate 21 and the laser alignment system 7 enables high-precision pipe connections. When the device is operational, the pipe clamping arm 1 ensures the pipes to be connected are securely and stably attached; simultaneously, the laser alignment system 7, mounted on the floating positioning plate 21, can quickly and accurately determine any misalignment between the two end faces. An example of how this feature can be technically implemented is as follows: After a technician places the laser emitter and receiver in the appropriate positions within the internal structure of the floating positioning plate 21, the power is turned on for initial alignment. Subsequently, based on feedback data, the clamping arm and screw are fine-tuned until the centerlines of the two pipe sections are completely aligned. Furthermore, manually rotating the manual wheel with a microscale can further optimize the movement distance to achieve finer-grained calibration requirements, ensuring connection accuracy.

[0041] In one embodiment, such as Figure 3 As shown, the guide frame 2 of the water pipe construction and docking device of this application is internally equipped with an adjustable support frame 8, which is, for example, located at the bottom of the guide frame 2. The support frame 8 can be flexibly adjusted in position according to the diameter of the pipe to be connected, and its center is kept stable during the pipe insertion into the sleeve. This design aims to solve the problem of possible misalignment when connecting pipes of different specifications on the construction site, ensuring accurate and efficient docking operations.

[0042] Specifically, the adjustable support frame 8 is located inside the guide frame 2, and its installation method allows the support frame 8 to move along the axial direction of the guide frame 2 and be fixed in the desired position. The structure of the support frame 8 typically includes multiple radial support components and a central positioning post. The radial support components are used to adjust to different diameters and can be fixed in position by means of elements such as locking screws; the central positioning post is used to ensure concentricity during pipe insertion. When connecting smaller diameter pipes, the components on the support frame 8 move closer together to fit the smaller size, while for larger diameter pipes, they open appropriately to accommodate the larger diameter.

[0043] In one technical solution, a slide rail or similar guiding mechanism is provided between the support frame 8 and the guide frame 2 to guide the radial movement of the support frame 8, ensuring stability and precise positioning. For example, the support frame 8 can be finely positioned by using a nut and screw structure or a hydraulic system. A manual or electric adjusting handwheel equipped with a differential scale is used to set and record the position parameters of the support frame 8, ensuring consistency and accuracy in repeated operations.

[0044] In one embodiment, the manual rotating wheel 32 of the water pipe construction and docking device of this application is equipped with a locking bolt 9. The manual rotating wheel 32 is installed on the outer part of the adjusting screw mechanism 3. The user can manually rotate the rotating wheel 32 to adjust the adjusting screw 31 with opposite directions of the double helix, thereby realizing the clamping and loosening operation of the pipe clamping arm 1 on the pipe. The manual rotating wheel 32 is designed with a precise differential scale, which can finely control the required advance distance or retraction amount during the clamping process, making the position adjustment more accurate and reliable when connecting pipes.

[0045] To prevent changes in the adjusted angle, a locking bolt 9 is installed on the manual rotating wheel 32. After manually adjusting the rotating wheel 32 to the appropriate angle, the locking bolt 9 can be tightened to secure the manual rotating wheel 32. Thus, even in the presence of mechanical vibration or external forces in the actual working environment, the locking structure prevents uncontrolled displacement of the manual rotating wheel 32 due to external forces, maintaining the preset value and ensuring the safety and accuracy of equipment operation.

[0046] For example, the locking bolt 9 can be made of a wear-resistant material when manufacturing the locking device. This material ensures that it does not wear excessively under frequent operation and maintains good self-locking performance. At the same time, during assembly, it is necessary to ensure that the locking bolt 9 is correctly positioned within the predetermined hole and does not obstruct the movement of the manual rotating wheel 32. With this design, when precise positioning is required, the operator first rotates the adjusting wheel for rough adjustment, then uses the matching tool to slightly tighten the locking bolt 9 until a slight resistance is felt. Once precise alignment is achieved, the bolt is then fully tightened to lock the position of the manual rotating wheel 32, effectively fixing the selected position and preventing any accidental slippage.

[0047] In one embodiment, the floating positioning plate 21 of the water pipe construction and docking device of this application is equipped with rolling shafts 10 to reduce the friction between the pipe and the device surface during transportation, thereby facilitating precise pipe docking. This design significantly optimizes construction efficiency and installation accuracy. Specifically, two sets of symmetrically installed floating positioning plates 21 are provided in the guide frame 2 of the device. To reduce the impact of friction and promote smooth transportation of pipes, each floating positioning plate 21 is equipped with multiple rows of rolling shafts 10, distributed along the direction of the pipe to be docked. In addition, the rolling shafts 10 and the floating positioning plates 21 are in a rolling contact mode, ensuring good adaptability and reducing wear even when facing pipes of different shapes and sizes.

[0048] For example, in achieving the above functions, the floating positioning plate 21 has a specific groove structure inside for accommodating the rolling shaft 10, which can be preloaded into the groove to form a stable connection. By rationally arranging the positions of the rolling shafts 10 on the floating positioning plate 21, each pipe entering the device can be subjected to a continuous and stable supporting force until the final docking step is completed. When a certain external force is applied to push the pipe forward along the axial direction, the direct friction is reduced, thus significantly reducing manpower consumption and equipment operating resistance, thereby ensuring smooth operation.

[0049] This structure not only improves work efficiency but also enhances construction safety and reliability, ensuring that the pipes remain in good condition throughout the entire transportation process and are not damaged or deformed due to unnecessary contact, thus guaranteeing the construction of a high-quality water supply system. However, its positive benefits will not be elaborated upon here; instead, the focus will be on describing its structural composition and working principle.

[0050] It is important to note that all components mentioned in this document are closely interconnected and work together to provide an efficient and stable pipeline docking platform. Furthermore, the positional relationships and assembly methods of the components within the device are consistent with the information provided in the background section, ensuring the accuracy and consistency of the technical documentation.

[0051] In one embodiment, return to reference Figure 1 The support bracket 4 of the water pipe construction docking device of this application is composed of telescopic hydraulic outriggers 11. The hydraulic outriggers 11 are located at the bottom of the support bracket 4 and are fixedly connected to it. The support bracket 4 is positioned below the pipe clamping arm 1 to reinforce the stability of the structure. Specifically, the hydraulic system is integrated within the hydraulic outriggers 11 and has an adjustable height function, thus flexibly responding to changes in various terrains. This design not only enhances the applicability of the equipment in different working environments but also ensures stability during operation. To achieve optimal working results, the telescopic hydraulic outriggers 11 can be height adjusted as needed and locked in different positions, providing a solid support platform for the entire docking device.

[0052] For example, a hydraulic transmission assembly consisting of a hydraulic cylinder and piston rod is installed inside each hydraulic outrigger 11. The hydraulic cylinder is connected to a hydraulic pump station via pipelines and is equipped with a pressure sensor to provide real-time feedback on the support status. By operating the valves through the control console, the pressure value of each hydraulic outrigger 11 can be precisely adjusted to achieve fine-tuning of height and maintain balance. When encountering uneven or sloping construction ground, multiple hydraulic outriggers 11 can be operated individually or in coordination to compensate for height differences, thereby ensuring that the entire device remains in a level and stable state to cope with different geographical conditions and ensure good operating conditions.

[0053] In one embodiment, the support bracket 4 of the water pipe construction and connection device of this application is equipped with a smart display screen 12, such as... Figure 1 As shown, the intelligent display screen 12 is used to intuitively read the data provided by the laser alignment system 7, enabling workers to quickly understand and adjust the alignment of the pipeline during construction. The support bracket 4 is located below the pipe clamping arm 1, primarily to provide overall structural stability and adapt to different terrain requirements. The intelligent display screen 12 is strategically positioned on one side or top of the support bracket 4, according to actual operational needs. This design not only enhances the system's integration but also provides on-site workers with an effective way to directly obtain crucial information.

[0054] The intelligent display screen 12 is installed in an easily visible operating area. Connected to the built-in circuitry and communicating with the laser alignment system 7 via a signal processing module, it ensures reliable and efficient real-time data transmission. This layout takes into account the complex environment of the construction site and the need for convenient operation by staff.

[0055] For example, the smart display screen 12 can connect to the laser alignment system 7 via a dedicated communication cable or wireless transmission. The dedicated communication cable can be a wear-resistant, interference-resistant industrial-grade cable, with one end connected to the input interface of the smart display screen 12 and the other end connected to the data acquisition card located inside the adjusting screw mechanism 3 or directly connected to the information processor near the laser emission source. The wireless transmission solution utilizes Bluetooth or Wi-Fi technology, with a communication module pre-installed in the support bracket 4, making the entire process simpler, eliminating the need for additional wiring, and improving the overall mobility and applicability of the device.

[0056] In one embodiment, such as Figure 1 As shown, the support bracket 4 of the water pipe construction docking device of this application is equipped with a docking screw 13 and a drive motor 14 connected thereto. The docking screw 13 also has threads in opposite directions at both ends. The support bracket 4, as the basic component of the entire device, is installed below the pipe clamping arm 1 to reinforce structural stability and enable the device to adapt to operation in various terrains, ensuring the balance of the equipment during use. The docking screw 13 is installed inside the support bracket 4, and the docking screw 13 is connected to the drive motor 14 through a suitable mechanical interface or coupling, allowing the drive motor 14 to directly drive the rotation of the docking screw 13.

[0057] Specifically, because the docking screw 13 is designed with a double helix and the threads at both ends are in opposite directions, this ensures that when it rotates, the two threads respectively push the corresponding parts or objects towards the center. When the drive motor 14 starts and drives the docking screw 13 to rotate forward or backward, this special thread design can effectively drive the two sets of pipe clamping arms 1 to move closer to each other or further away from each other along the horizontal axis. In this way, after the pipe has been precisely positioned, it can be moved smoothly under load with the help of the clamping arms until they are accurately aligned and successfully joined. This configuration ensures that a stable force is applied during the drive process and helps prevent positional deviation problems caused by asymmetrical forces. For example, the drive motor 14 executes precise rotational movements according to control commands to ensure that the screw can rotate evenly and stably, thereby driving the two opposing pipe clamping arms 1 to move towards each other in the required direction until they contact each other, thereby achieving the expected pipe docking goal.

[0058] In actual operation, when this device is used, the pipe clamping arm 1 can firmly clamp and fix the pipes to be connected, ensuring that the pipe position remains unchanged during the connection process. Then, the guide frame 2 is installed at the end of the pipe clamping arm 1, allowing the two pipe sections to be connected to be accurately aligned with the center line under axial guidance. Two sets of floating positioning plates 21 are symmetrically installed inside the guide frame 2 to further assist in precise pipe alignment. The adjusting screw mechanism 3 is connected to the pipe clamping arm 1, and the adjusting screw 31 can be manually fine-tuned by the manual rotating wheel 32. The opposing action of the double helix stabilizes the position of the pipe, and the manual rotating wheel 32 with a differential scale can precisely control the distance the pipe moves. Finally, the support bracket 4 is placed below the pipe clamping arm 1 to reinforce structural stability and adapt to operation under different terrain conditions, ensuring the balance of the entire device during construction, thereby completing a precise and efficient pipe connection.

[0059] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
