Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection devices, and in particular relates to an anti-rotation lifter for water and oil pipelines. Background Art

[0002] Vibroflotation is a common method for reinforcing weak foundations. It typically increases soil density through the vibration and impact of a vibrator. Piling operations using a vibrator require both water and oil pipes for hydraulic power. However, the continuous rotation and vibration of the vibrator during operation can easily cause torsional forces in the oil and water pipes, leading to entanglement, twisting, and even damage. This not only increases pipeline maintenance and replacement costs but can also negatively impact construction efficiency and safety.

[0003] In existing technology, anti-twist devices are commonly added to pipe connections to mitigate or prevent torsional damage. However, some anti-twist devices fail to fully consider the synchronization issues associated with vibrator rotation during their design, resulting in limited anti-twist effectiveness. Furthermore, some devices lack a compact design, making them incompatible with both water and oil pipe connections, limiting their scope of application. These issues limit the effectiveness of existing devices in actual construction, preventing them from fully meeting project requirements. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the utility model is to provide a water-oil pipeline anti-rotation lifter, which can ensure the relative stillness of the oil pipe and the water pipe when the vibrator rotates, thereby improving the service life of the pipeline and construction safety.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A water and oil pipeline anti-rotation lifter comprises a traction head, wherein the traction head is provided with a passage for passing the oil pipe and the water pipe, and a connector for connecting a steel rope is provided at the top of the traction head;

[0007] The lower end surface of the traction head is connected to an outer sleeve, and the inner side of the outer sleeve is rotatably connected to an inner sleeve;

[0008] A roller is provided between the outer kit and the inner kit;

[0009] The bottom of the inner sleeve is connected with a guide rod connecting piece, the inner side of the guide rod connecting piece is provided with a hydraulic loop, and the outer side of the guide rod connecting piece is connected with a telescopic guide rod.

[0010] Furthermore, a first stopper is provided at the bottom of the outer sleeve;

[0011] A second stopper is provided on the outer side of the top of the inner sleeve;

[0012] The roller is located between the first stopper and the second stopper.

[0013] Furthermore, the inner bottom of the traction head is connected to a fixing frame, and the fixing frame is connected to the outer side of the upper end of the hydraulic loop;

[0014] The lower end of the hydraulic loop is connected to the innermost top of the telescopic guide rod.

[0015] Furthermore, a flange ring is fixedly connected to the outer side of the bottom end of the traction head.

[0016] Furthermore, a through slot and a through hole are formed through the side surface of the connector, the through slot and the through hole are arranged alternately, and a pin connection column is inserted into the through hole.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This utility model provides an anti-rotation lifter for water and oil pipelines. Through the coordinated design of a traction head, outer sleeve, inner sleeve, and rollers, it effectively solves the existing problem of twisting of the oil and water pipes caused by the rotation of the vibrator. The channel opened in the traction head provides a stable passage for the oil and water pipes, while the connector design on the top ensures the security of the steel rope connection. The rotational connection between the outer and inner sleeves, and the stable support of the rollers in between, achieves synchronous rotation of the inner and outer sleeves when the vibrator rotates, thereby keeping the hydraulic loop and the connected oil pipe relatively stationary, avoiding entanglement and twisting of the oil and water pipes, and significantly improving the reliability and safety of construction.

[0019] The first stop at the bottom of the outer kit and the second stop at the top of the inner kit form a two-way restriction on the roller, so that the roller can always remain within the appropriate working range; this design effectively prevents roller misalignment caused by external vibration or rotational load, ensuring smooth rotation between the inner and outer kits; compared with the existing technology, this optimized structure extends the service life of the device and reduces the frequency of maintenance due to roller wear or failure.

[0020] The utility model firmly connects the input and output ends of the hydraulic loop with the oil pipe through the combination of the fixing frame and the hydraulic loop, and realizes the height adjustability of the device through the layered structure design of the telescopic guide rod. This design is not only suitable for the requirements of different construction depths, but also ensures the stability of the pipeline connection. Even in complex construction environments, it can avoid damage caused by excessive stretching or compression of the oil pipe and water pipe, thereby improving the adaptability of the equipment.

[0021] The setting of the flange ring further enhances the fixing performance of the traction head and ensures the sealing between the traction head and the lower structure; this design effectively solves the problems of loosening and leakage that are prone to occur in traditional connection devices in strong vibration environments, and improves the overall structural stability and durability of the device; at the same time, through the stable connection of the flange ring, the installation and disassembly of the device is also more convenient, thereby improving construction efficiency.

[0022] The staggered design of the through slots and through holes on the side of the connector, combined with the plug-in method of the pin-connecting column, provides the steel rope with the functions of quick installation and firm connection; this structure solves the problems of slippage and falling off that are prone to occur during the traditional steel rope connection process, while improving the safety of the connection between the traction head and the steel rope; the implementation of this function significantly reduces the failure rate of the equipment that may occur during long-term high-intensity construction.

[0035] See Figure 1-4 A water and oil pipeline anti-rotation lifter includes a traction head 1; a channel 11 for passing oil pipes and water pipes is opened on the traction head 1, and the channel 11 runs through the upper part of the traction head 1 and has enough space to accommodate oil pipes and water pipes of different diameters; a connector 12 for connecting a steel rope is provided on the top of the traction head 1, and the connector 12 ensures that the steel rope can be firmly connected through a compact structure design; the bottom end of the traction head 1 is connected to an outer sleeve 2 in a firmly fixed manner; the inner side of the outer sleeve 2 is rotatably connected to an inner sleeve 3 through a precision-machined bearing, and the inner sleeve 3 can achieve efficient relative rotation with the outer kit 2; evenly distributed rollers 4 are provided between the outer kit 2 and the inner kit 3, and the rollers 4 further improve the smoothness and durability of rotation by reducing friction; a guide rod connector 5 is tightly mounted on the bottom of the inner kit 3, and a hydraulic loop 7 is provided on the inner side of the guide rod connector 5. The hydraulic loop 7 realizes the input and output functions of oil through its built-in hydraulic channel; a telescopic guide rod 8 is installed on the outer side of the guide rod connector 5, and the length of the telescopic guide rod 8 can be adjusted as needed to adapt to different construction scenarios.

[0036] See Figure 1 and Figure 3 A first stop 21 is provided at the bottom of the outer kit 2, and the first stop 21 limits the axial displacement of the roller 4 in a reliable fixing manner; a second stop 31 is provided on the top outer side of the inner kit 3, and the position design of the second stop 31 ensures that the roller 4 always remains within the limited range; the roller 4 is located between the first stop 21 and the second stop 31, and the roller 4 forms a stable support structure between the first stop 21 and the second stop 31 through a uniform force layout, thereby avoiding the deviation or failure of the roller 4 caused by external loads, thereby ensuring the long-term reliable operation of the inner kit 3 and the outer kit 2.

[0037] See Figure 3-4 The inner bottom of the traction head 1 is connected to a fixing bracket 6 by bolts or welding, and the fixing bracket 6 has the function of enhancing stability; the fixing bracket 6 is tightly connected to the outer side of the upper end of the hydraulic loop 7. The design of the hydraulic loop 7 enables it to rotate synchronously with the vibrator when the pipeline is connected; the lower end of the hydraulic loop 7 is fixed to the innermost top of the telescopic guide rod 8 by a firm connection. The layered structure of the telescopic guide rod 8 can be freely telescoped and adjusted according to the actual working conditions of the vibrator to ensure that the connection between the water pipe and the oil pipe is firm and will not be affected by additional torsional force.

[0038] See Figure 2 A flange ring 14 is fixedly connected to the outside of the bottom end of the traction head 1, and the flange ring 14 is tightly connected to other devices through precisely machined screw holes; the structural design of the flange ring 14 not only provides additional fixed support, but also ensures the sealing between the traction head 1 and the lower structure, thereby improving the overall seismic resistance and durability of the device.

[0039] See Figure 2 The side of the connecting head 12 is penetrated by a through groove 121 and a through hole 122, and the through groove 121 and the through hole 122 are distributed in a staggered manner; the through groove 121 is convenient for quickly placing the buckle end of the steel rope therein, and a pin connection column 13 is inserted into the through hole 122. The pin connection column 13 is designed with precisely matched dimensions and materials to ensure that the steel rope will not fall off or slip during the connection process, thereby improving the connection stability and reliability between the traction head 1 and the steel rope.

[0040] The working principle of this utility model is:

[0041] When in use, the buckle end of the traction steel rope is placed in the through slot 121, and the pin connection column 13 is passed through the connecting buckle of the steel rope to connect the steel rope to the connector 12;

[0042] Insert the oil pipe and water pipe into the channel 11, connect one end of the oil pipe to the input end of the top of the hydraulic loop 7, and connect the oil pipe between the output end of the bottom of the hydraulic loop 7 and the vibrator;

[0043] During the process of using the vibrator for piling, when the vibrator rotates, the inner sleeve 3 and the outer sleeve 2 will rotate synchronously, and the hydraulic loop 7 and the oil pipe connected to the vibrator will remain relatively still, thereby avoiding the oil pipe from twisting during the piling process.
