Description

Technical Field

[0001] The present application relates to the technical field of pump pipe docking, and in particular to a pumping steel pipe docking locking device. Background Art

[0002] Traditional intelligent trolley-based intelligent pouring systems use standard pipe clamps to connect pumped steel pipes. This connection method has numerous drawbacks, including time-consuming and labor-intensive processes and the need for significant manual labor to complete the pumped steel pipe docking operation. Therefore, research on a locking device that can more efficiently and conveniently achieve this is crucial.

[0003] The traditional method for connecting pumped steel pipes requires the use of pipe clamps attached to the outside of the pipe joints. The process involves first connecting the pipes and then tightening the clamps. In practical applications, particularly in intelligent pouring systems used in tunnel trolleys, this traditional method exhibits significant shortcomings when connecting rotating elbows to horizontal elbows. Not only is the operation cumbersome, but the resulting connection quality is also low. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present application provides a pumping steel pipe docking locking device to solve the above problems.

[0005] The present application provides a pumping steel pipe butt locking device, comprising:

[0006] Pump tube self-locking parts;

[0007] A positioning assembly, wherein the pump tube self-locking member is movably connected to the positioning assembly;

[0008] A hydraulic telescopic device is connected to the outer wall of the pump pipe to be docked, and is telescopic along the extension direction of the pump pipe to be docked. The hydraulic telescopic device is driven and connected to the pump pipe self-locking piece. When the pump pipe to be docked is docked with the pump pipe to be docked, the hydraulic telescopic device can drive the pump pipe self-locking piece to buckle on the edge of the flange of the pump pipe to be docked and lock the flange.

[0009] In the pumping steel pipe docking locking device provided in the present application, the docking locking device includes two or more devices, which are arranged at intervals around the outer wall of the pump pipe to be docked.

[0010] In the pumping steel pipe docking locking device provided in the present application, the docking locking device includes two devices, which are symmetrically arranged on the outer wall of the pump pipe to be docked.

[0011] In the pumping steel pipe docking locking device provided in the present application, the hydraulic expansion device includes a hydraulic expansion joint and a fastener, and the hydraulic expansion joint is connected to the pump pipe to be docked through the fastener.

[0012] In the pumping steel pipe docking locking device provided in the present application, the positioning assembly includes a gate-type fixed steel plate and a fixed pin shaft. The gate-type fixed steel plate is connected to the outer wall of the pump pipe to be docked. A sliding hole is provided on the pump pipe self-locking part. The fixed pin shaft is inserted into the sliding hole and passes through the sliding hole to be connected to the gate-type fixed steel plate.

[0013] In the pumping steel pipe docking locking device provided in the present application, one end of the pump pipe self-locking member is rotatably connected to the hydraulic telescopic device through a pin shaft, and the other opposite end is buckled together with the docking pump pipe.

[0014] In the pumping steel pipe docking locking device provided in the present application, the pump pipe self-locking part includes a main handle and a bent buckle portion. The sliding hole is opened on the main handle and is opened along the length direction of the main handle. The main handle can move along the fixed pin shaft. The bent buckle portion is hook-shaped. The bent buckle portion is connected to the main handle. The edge of the flange is provided with a protrusion corresponding to the bent buckle portion, so that the two can be fastened together when the main handle is retracted.

[0015] In the pumping steel pipe docking locking device provided in the present application, when the main handle extends forward, the bent buckle portion disengages from the flange.

[0016] This application has the following technical effects:

[0017] The present invention's pumped steel pipe docking and locking device overcomes the shortcomings of traditional pipe clamp connection methods. Traditional methods require manual operation of pipe clamps during docking, which is time-consuming and labor-intensive. However, this device utilizes a hydraulic expansion mechanism to drive the pump pipe self-locking mechanism, significantly reducing manual operation and significantly improving the speed and efficiency of pumped steel pipe docking. It is particularly suitable for complex working conditions such as tunnel trolley intelligent pouring systems, which require high construction efficiency.

[0018] In complex applications such as connecting a traditional rotary elbow to a horizontal elbow, conventional pipe clamp connections are prone to loose connections and poor quality. This device uses a hydraulic expansion mechanism to retract the pump pipe's self-locking member, securing it to the flange edges of the two connected pipes, achieving a secure and stable connection. This tight connection effectively prevents leaks and other problems caused by loose connections during use, significantly improving connection quality and ensuring the stable operation of the intelligent pouring system.

[0034] refer to Figure 1-Figure 2 A pumping steel pipe docking locking device includes: a pump pipe self-locking part 10; a positioning component, the pump pipe self-locking part 10 is movably connected to the positioning component; a hydraulic expansion and contraction device 20, which is connected to the outer wall of the pump pipe 31 to be docked and expands and contracts along the extension direction of the pump pipe 31 to be docked. The hydraulic expansion and contraction device 20 is driven and connected to the pump pipe self-locking part 10. When the pump pipe 30 to be docked is docked with the pump pipe 31 to be docked, the hydraulic expansion and contraction device 20 can drive the pump pipe self-locking part 10 to buckle on the edge of the flange 50 of the pump pipe 30 to be docked and lock the flange 50.

[0035] In the initial state, the pump pipe self-locking member 10 is connected to the pump pipe 31 to be docked through the positioning assembly, and the hydraulic expansion and contraction device 20 is installed on the outer wall of the pump pipe 31 to be docked, and establishes a driving connection with the pump pipe self-locking member 10. When the pump pipe 30 to be docked and the pump pipe 31 to be docked begin the docking operation, as the two pump pipes gradually approach and complete the docking, the hydraulic expansion and contraction device 20 starts. Under the action of hydraulic power, the hydraulic expansion and contraction device 20 drives the pump pipe self-locking member 10 to retract, and the pump pipe self-locking member 10 is tightly buckled on the edge of the flange 50 of the pump pipe 30 to be docked, thereby firmly locking the two docked pumping steel pipes together, ensuring the stability and sealing of the connection between the two steel pipes.

[0036] This design effectively improves the efficiency of connecting pumped steel pipes and reduces manual labor compared to traditional pipe clamp connections. It also ensures high-quality connections, prevents loosening at the joints, and ensures stability under complex working conditions, ensuring the normal operation of the pouring system.

[0037] Initially, the device is in a ready state, with the hydraulic expansion and contraction device 20 connected to the pump pipe self-locking member 10 and installed on the intended pump pipe 31. During docking, the pump pipe 30 to be docked is brought close to the intended pump pipe 31. After docking is completed, the hydraulic expansion and contraction device 20 drives the pump pipe self-locking member 10 to move, causing it to snap onto the edge of the flange 50 of the intended pump pipe 30 and lock the flange 50, completing the docking and locking.

[0038] The docking locking devices include two or more devices that are spaced apart around the outer wall of the pump tube 31 to be docked.

[0039] The surrounding arrangement of multiple docking locking devices can make the connection more uniform and stable, and apply locking force to the docked steel pipes from multiple directions, further enhancing the reliability of the connection. It is especially suitable for pumping steel pipe connections that are subject to greater pressure or complex stress conditions.

[0040] During the docking process, the hydraulic telescopic devices 20 of each docking locking device work synchronously or independently, driving their respective pump pipe self-locking parts 10 to move toward the edge of the flange 50 of the pump pipe 30 to be docked, and locking in multiple directions at the same time to ensure that the docking point is all-round stable.

[0041] In some embodiments, the docking locking devices include two, which are symmetrically arranged on the outer wall of the pump tube 31 to be docked.

[0042] Two symmetrically positioned docking locks ensure a secure connection while simplifying the structural design, reducing cost and complexity. In situations where forces are relatively evenly distributed, they can meet basic connection stability requirements and facilitate installation and maintenance.

[0043] When two pump pipes are docked, two symmetrical hydraulic telescopic devices 20 respectively drive the corresponding pump pipe self-locking parts 10, causing them to move simultaneously toward the edge of the flange 50 of the pump pipe 30 to be docked, applying locking force in the symmetrical direction to complete stable docking.

[0044] The hydraulic expansion and contraction device 20 includes a hydraulic expansion joint and a fastener. The hydraulic expansion joint is connected to the pump pipe 31 to be docked via the fastener.

[0045] The hydraulic expansion joint is connected by fasteners, making the installation of the hydraulic expansion joint 20 on the intended pump pipe 31 more secure and reliable. This connection method ensures that the hydraulic expansion joint 20 will not loosen or shift due to factors such as vibration during operation, thereby ensuring the accuracy and stability of its driving of the pump pipe self-locking member 10.

[0046] The fasteners tightly fix the hydraulic expander on the pump pipe 31 to be docked. During the docking process, the hydraulic expander expands and contracts according to the instructions, and through the connection with the pump pipe self-locking part 10, it accurately drives the pump pipe self-locking part 10 to perform the locking action, thereby realizing the docking locking function.

[0047] Another structural setting of the hydraulic telescopic device 20, the overall structure of the hydraulic telescopic device 20 can be in the form of a combination of a hydraulic drive cylinder and a guide rail slider. The cylinder body of the hydraulic drive cylinder is fixed to the outer wall of the intended docking pump pipe 31 through a connecting seat. The connecting seat serves as a fastening component, and its structure is similar to an embracing clamp. The interior of the connecting seat is provided with an arc-shaped groove that matches the outer wall of the intended docking pump pipe 31. The groove is embedded with a rubber pad to increase friction and protect the surface of the pump pipe. Bolt holes are provided on both sides of the connecting seat, and the connecting seat is tightly fixed to the pump pipe with high-strength bolts.

[0048] A linear guide rail is installed along the outer wall of the intended docking pump tube 31, secured by welding or bolting (using pre-installed screw holes in the pump tube). The piston end of the hydraulic cylinder is connected to a slider, which engages the guide rail. The pump tube self-locking member 10 is connected to the slider via a connecting rod mechanism. When the hydraulic cylinder extends or retracts, the piston drives the slider along the guide rail, which in turn drives the pump tube self-locking member 10 via the connecting rod mechanism.

[0049] In the initial state, the hydraulic drive cylinder is firmly mounted on the pump pipe 31 to be docked through the connecting seat. When the pump pipe 30 to be docked begins to dock with the pump pipe 31 to be docked, the hydraulic drive cylinder extends and retracts according to the control system instruction. The piston pushes the slider to move along the guide rail, and the slider drives the pump pipe self-locking part 10 to move along the set path through the connecting rod mechanism. When the docking is completed, the pump pipe self-locking part 10 is buckled onto the edge of the flange 50 of the pump pipe 30 to be docked under the action of the connecting rod mechanism and locks the flange 50. This structural setting ensures the stability and accuracy of the hydraulic telescopic device 20 through the precise guidance of the guide rail slider and the firm fixation of the connecting seat, and realizes the same docking locking function as the original design.

[0050] The encircling, clamp-shaped connector evenly distributes pressure on the outer wall of the pump tube, reducing localized stress concentrations. The rubber pad not only prevents damage to the pump tube surface from the connector but also enhances the stability of the connection in vibrating environments, preventing vibration-induced loosening of the fastener. The use of high-strength bolts further ensures connection reliability, ensuring that the hydraulic expansion joint 20 remains securely fixed to the intended pump tube 31 under all operating conditions.

[0051] In some embodiments, the positioning assembly includes a gate-type fixing steel plate 40 and a fixing pin 41. The gate-type fixing steel plate 40 is connected to the outer wall of the pump tube 31 to be docked. A sliding hole 42 is provided on the pump tube self-locking part 10. The fixing pin 41 is inserted into the sliding hole 42 and passes through the sliding hole 42 to be connected to the gate-type fixing steel plate 40.

[0052] This positioning assembly design ensures more stable and precise movement of the pump tube self-locking member 10. The combination of the gate-type fixing steel plate 40 and the fixing pin 41 restricts the movement trajectory of the pump tube self-locking member 10, ensuring that it can accurately snap onto the edge of the flange 50 under the drive of the hydraulic expansion and contraction device 20, thereby improving the success rate and reliability of the docking lock.

[0053] The gate-type fixing steel plate 40 is fixed to the outer wall of the pump pipe 31 to be connected, and the fixing pin 41 passes through the sliding hole 42 of the pump pipe self-locking member 10, connecting the pump pipe self-locking member 10 to the gate-type fixing steel plate 40. When the hydraulic expansion and contraction device 20 is driven, the pump pipe self-locking member 10 can only move along the direction defined by the fixing pin 41, accurately moving toward the edge of the flange 50 of the pump pipe 30 to be connected to achieve locking.

[0054] One end of the pump tube self-locking member 10 is rotatably connected to the hydraulic expansion and contraction device 20 via a pin shaft, and the other opposite end is buckled together with the pump tube with docking.

[0055] One end is connected by a pin shaft so that the pump pipe self-locking part 10 can rotate flexibly under the drive of the hydraulic telescopic device 20, better adapting to different docking conditions, ensuring that it can be accurately buckled on the pump pipe 30 to be docked under various working conditions, thereby improving the versatility and adaptability of the device.

[0056] During the extension and retraction process of the hydraulic retractable device 20, the pump tube self-locking member 10 can be rotated to adjust the angle through the pin rotation connection, so that its other end can be smoothly buckled with the pump tube 30 to be connected, achieving a stable connection.

[0057] The pump tube self-locking part 10 includes a main handle 101 and a bent buckle portion 102. The sliding hole 42 is opened on the main handle 101 and is opened along the length direction of the main handle 101. The main handle 101 can move along the fixed pin shaft 41. The bent buckle portion 102 is in a hook shape and is connected to the main handle 101. The edge of the flange 50 is provided with a protrusion corresponding to the bent buckle portion 102, so that the two can be fastened together when the main handle 101 is retracted.

[0058] The design of the main handle 101 and the curved buckle portion 102 makes the lock more secure. The main handle 101 can move along the fixed pin 41 to ensure the accuracy of movement. The curved buckle portion 102 cooperates with the protrusion on the edge of the flange 50 to form a tight fit when the main handle 101 retracts, effectively preventing the joint from loosening and enhancing the stability and sealing of the connection.

[0059] When the main handle 101 retracts along the fixed pin 41 under the drive of the hydraulic telescopic device 20, the bent buckle portion 102 interacts with the protrusion on the edge of the flange 50, and the bent buckle portion 102 tightly fastens the protrusion to achieve a firm locking of the flange 50 and complete the docking.

[0060] When the main handle 101 is extended, the curved buckle portion 102 is disengaged from the flange 50. This design, in which the main handle 101 is extended to disengage the curved buckle portion 102 from the flange 50, facilitates both pre-mating preparations and post-mating disassembly and maintenance, making the device more flexible and easier to operate and manage.

[0061] Working Principle: To dock, the main handle 101 extends forward, disengaging the curved buckle 102 from the flange 50 to create space for the two pump tubes to connect. After docking, the main handle 101 retracts, and the curved buckle 102 reengages the flange 50 to lock the connection. To disassemble, the main handle 101 extends forward to release the connection.

[0062] In some embodiments, a calibration device is also provided, comprising an infrared laser detector, a circular track, and a driver. The infrared laser detector is mounted on a flexible, movable detection platform. This detector is equipped with a high-precision infrared laser transmitter and receiver, capable of emitting an infrared laser beam toward a target and receiving the reflected light. By meticulously analyzing the reflected light, the detector can accurately determine the docking condition of the two tubes.

[0063] The annular track wraps around the outer wall of the pump pipe 30 to be connected, near the flange 50. The track's inner diameter is slightly larger than the outer diameter of the pipe to be connected, ensuring adequate clearance between the track and the pipe. The track is securely fastened to the pipe via welding or high-strength bolts, ensuring stability throughout use without loosening or displacement.

[0064] The driver is installed on the circular track, and the two are connected by rollers or sliders. This connection method can effectively reduce friction and make the movement of the driver on the track smoother. A motor and a transmission mechanism are set inside the driver. The motor drives the roller or slider through transmission forms such as gears, belts or chains, thereby driving the driver to move smoothly along the circular track. The driver and the detection platform are connected by a rigid connecting rod. In this way, when the driver moves on the circular track, it can pull the detection platform to move synchronously, and finally enable the infrared laser detector to perform a comprehensive inspection around the outer edge of the flange 50 to be connected to the pipe.

[0065] Before the pumped steel pipe docking operation begins, the detection system, consisting of an infrared laser detector, a ring track, and a driver, is activated and in standby mode. The ring track and driver are accurately installed on the pipe to be docked, and the infrared laser detector is calibrated and ready to transmit and receive infrared laser signals.

[0066] When the pumped steel pipe docking operation begins, the driver begins circular motion on a circular track. As the driver moves, it drives the infrared laser detector, via a rigid connecting rod, along the circular track, continuously circling the outer edge of the flange 50 of the pipe to be docked. During this process, the infrared laser detector continuously emits an infrared laser beam toward the flange 50. When the laser beam strikes the surface of the flange 50, it generates reflected light, which is then received by the detector.

[0067] The signal processing unit within the detector conducts an in-depth analysis of the received reflected light signal. If the two pumping steel pipes are precisely docked and without any offset, the parameters of the reflected light, such as intensity, angle, and reception time, will fall within the preset standard value range. However, if the two pipes are offset during the docking process, these parameters of the reflected light will change accordingly. For example, if flange 50 is offset in a certain direction, the angle and intensity of the reflected light in that direction will differ from those in the normal docking state. Based on these changes in parameters, the detector determines whether the two pipes are precisely docked and whether there is any offset, and promptly transmits the test results to the control system.

[0068] The high-precision detection capabilities of infrared laser detectors enable immediate detection of even the slightest misalignment between two pumping pipes during docking. This allows operators to make adjustments before the docking is complete, significantly improving docking accuracy. High-precision docking effectively reduces the subsequent problems caused by inaccurate docking, such as pipe leaks and unstable connections.

[0069] Throughout the docking process, the detector continuously monitors the docking status in real time and quickly provides feedback to the operator or control system. This real-time feedback mechanism enables the docking operation to be completed smoothly during dynamic adjustments, ensuring the stability and consistency of docking quality every time and avoiding possible oversights and delays caused by manual inspections.

[0070] Because the detector can quickly and accurately detect problems during the docking process, it reduces the time spent on repeated adjustments and inspections due to unsatisfactory docking, thereby effectively improving overall work efficiency. This efficiency improvement is particularly significant in large-scale pumping steel pipe docking projects, significantly shortening the project schedule.

[0071] Precise docking plays a vital role in improving the reliability of the entire pumping steel pipe system. It can reduce the risk of failure caused by poor connections, extend the service life of the system, and thus reduce maintenance and replacement costs, providing a strong guarantee for the smooth progress and long-term stable operation of the entire project.

[0072] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
