Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pipeline installation, in particular to a water conservancy pipeline docking device. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. In water conservancy projects, water conservancy pipelines are indispensable. In order to facilitate the connection of water conservancy pipelines, water conservancy pipeline connection auxiliary devices are often used.

[0003] For example, a water conservancy pipeline docking device with application number CN202321609026.7 includes a U-shaped bracket, a motor, a bidirectional screw and a support plate. The outer wall of the U-shaped bracket is equipped with a motor, and the output end of the motor extends into the inner wall of the U-shaped bracket. The output end of the motor is equipped with a bidirectional screw. The outer wall of the bidirectional screw is sleeved with a support plate, and the support plate is engaged with the bidirectional screw. The utility model is mainly used to support the bidirectional screw and the auxiliary rod by installing the U-shaped bracket. The motor can drive the bidirectional screw to rotate, the support plate is used to support the auxiliary ring, and the auxiliary ring is used for the end of the water conservancy pipeline to pass through. The hydraulic cylinder can control the movement of the fixed arc claw. The fixed arc claw cooperates with the auxiliary ring to clamp and fix the end of the water conservancy pipeline. The bidirectional screw can drive the two support plates to move relative to each other, that is, the auxiliary ring is also the water conservancy pipeline to move relative to each other, so as to facilitate the docking of the water conservancy pipeline.

[0004] The above patent proposes that when the water conservancy pipeline docking device is in use, the cooperation between the fixed arc claws and the auxiliary ring can be used to clamp and fix pipelines of different diameters. However, since the inner curvature of the fixed arc claws and the auxiliary ring is constant, when clamping pipelines of different diameters, there are usually only two line contact positions, and the clamping stability is poor.

[0005] Therefore, we propose a water conservancy pipeline docking device to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a water conservancy pipeline docking device to solve the problem that the water conservancy pipeline docking device proposed in the above background technology can clamp and fix pipelines of different diameters by utilizing the cooperation between the fixed arc claws and the auxiliary ring when in use. However, since the inner curvature of the fixed arc claws and the auxiliary ring is constant, when clamping pipelines of different diameters, there are usually only two linear contact positions, resulting in poor clamping stability.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a water conservancy pipeline docking device, comprising a concave base, a driving assembly installed at the middle part of the top of the concave base, a first clamping piece is respectively provided at both ends of the top of the concave base, and a driving protrusion is fixedly installed at the bottom of the first clamping piece, a concave telescopic frame is fixedly installed on the outer wall of one side of the first clamping piece, and a second clamping piece is fixedly installed on the upper end of the concave telescopic frame, and a two-way telescopic rod is installed between the second clamping pieces, a concave bracket is fixedly installed at the middle part of the concave base, and a hydraulic telescopic column is fixedly installed on the top of the concave bracket.

[0008] Preferably, linear sliding columns are fixedly installed on both sides of the top of the concave base.

[0009] Preferably, the drive assembly includes a drive motor and a double-threaded column fixedly mounted on the output end of the drive motor.

[0010] Preferably, the first clamping member includes a mounting base and a fixed clamping block fixedly installed on one side of the top surface of the mounting base, a movable clamping block is slidably provided on the other side of the top surface of the mounting base, and a threaded knob is rotatably installed on the mounting base.

[0011] Preferably, a top slide groove is provided on the other side of the top surface of the mounting base, the fixed clamping block includes a lifting block and a clamping block movably installed on the upper end of the lifting block, the movable clamping block includes a sliding top block and a clamping block movably installed on the upper end of the sliding top block, a sliding protrusion is fixedly installed in the middle of the bottom surface of the sliding top block, and a threaded hole is provided on the sliding protrusion.

[0012] Preferably, the composition and connection mode of each structure in the second clamping member are the same as the composition and connection mode of each structure in the first clamping member.

[0013] Preferably, the bidirectional telescopic rod includes a middle connecting sleeve and telescopic sliders respectively slidably inserted at both ends of the middle connecting sleeve, and the second clamping members are respectively fixedly mounted on the outer ends of the telescopic sliders.

[0014] A threaded driving hole is provided at the middle of the driving protrusion, and circular sliding holes are respectively provided at both sides of the driving protrusion.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When it is necessary to dock the pipes, the ends of the pipes can be inserted between the first clamping piece and the second clamping piece respectively. Then, the hydraulic telescopic column is started. The output end of the hydraulic telescopic column will drive the second clamping piece to move downward through the two-way telescopic rod. By setting the clamping block and the clamping block, the pipe can be limited to four-way line contact. This not only greatly improves the stability of pipe clamping, but also realizes the clamping and fixing of pipes of different diameters in the center.

[0017] 2. By rotating the threaded knob, the movable clamp can be driven to move toward the fixed clamp under the drive of the thread, thereby changing the distance between the fixed clamp and the movable clamp, making the docking device suitable for pipes with large diameter differences, thereby improving the adaptability of the device.
