Description

Technical Field

[0001] This utility model relates to the field of sealing detection technology, and in particular to a sealing detection device for ship pipelines. Background Technology

[0002] During the production of ship pipelines, it is necessary to conduct sealing tests on the welded pipe sections. Traditional testing equipment mostly adopts a single-station, pipe-by-pipe testing method, which suffers from low efficiency and easy positioning deviation. Especially for small-diameter, thin-walled pipes, mechanical clamping can easily cause pipe deformation, affecting the testing accuracy. Existing equipment generally lacks flexible buffer mechanisms, making it difficult to meet testing requirements. Therefore, a ship pipeline sealing testing device is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0004] Therefore, one objective of this utility model is to provide a ship pipeline sealing testing device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of the present invention provides a ship pipeline sealing inspection device, including a frame, a back frame, and an electric cylinder. The back frame is installed on the top of the frame, and the electric cylinder is installed above the back frame. The electric cylinder is installed vertically.

[0006] The front of the back frame is movably connected to a slide, and the end of the output end of the electric cylinder is connected to the slide.

[0007] The height of the carriage is adjustable, and symmetrically distributed cylinders are mounted on the front of the carriage, with the cylinders installed horizontally.

[0008] The front of the slide is fixedly connected to a rail, the end of the cylinder output is fixedly connected to a slide block, and the bottom of the slide block is fixedly connected to a side frame.

[0009] The main body of the equipment is supported by a welded frame, with a back frame vertically mounted on top to form the main frame of the inspection station. A vertical electric cylinder is bolted to the upper part of the back frame, and the output end of the electric cylinder is connected to a slide that can be raised and lowered along the guide rail of the back frame to achieve the adjustment of the inspection height.

[0010] Two sets of pneumatic components are symmetrically arranged on the front of the carriage: each set includes a horizontal cylinder and its driven slide, with a side frame bent at an angle connected to the bottom of the slide. A cup-shaped sealing cover is fixed to the inside of the side frame, and a rubber sealing ring is embedded in its edge to form an airtight interface. The two sets of side frames, together with the central frame through telescopic rods and sleeved springs, constitute an anti-collision mechanism.

[0011] The slide is movably connected to the track, and several positioning claws are installed on the top of the frame;

[0012] A sealing cover is fixedly connected to the inner side of the side frame. The sealing cover is bowl-shaped. Several interfaces are fixedly connected to the surface of the side frame. The interfaces are connected to the corresponding sealing covers.

[0013] A middle frame is fixedly connected to the front of the back frame, and telescopic rods and springs are fixedly connected to both sides of the middle frame. Top heads are fixedly connected to the ends of the telescopic rods and springs, and the ends of the top heads abut against the side frames.

[0014] Preferably, in any of the above solutions, the frame is welded to the back frame, and the electric cylinder is installed with screws.

[0015] The above technical solution achieves simultaneous detection of multiple pipelines through an innovative pneumatic positioning structure and elastic buffer mechanism.

[0016] Preferably, the back frame is equipped with an adapter rail for the carriage, and the rail is made of stainless steel.

[0017] Multi-pipeline synchronous detection:

[0018] The machine table is equipped with multiple sets of positioning claws, each set of two claws holding one pipe to be tested. During testing, the operator places multiple pipe samples in adjacent positioning claw sets simultaneously, and the inner sealing cover is retracted by a cylinder to simultaneously clamp both ends of the pipe, forming a closed testing chamber.

[0019] Inflation detection system:

[0020] The sealing cover on one side is connected to an inert gas source via an interface on the side frame. The following steps are performed during testing:

[0021] ① Inflation stage: Inject inert gas at a set pressure (usually 0.3-0.6MPa) into the sealed cavity;

[0022] ② Pressure holding stage: Turn off the gas supply and maintain the pressure for 5-10 minutes;

[0023] ③ Testing phase: Monitor the pressure drop value using a pressure sensor (allowable tolerance ±2%).

[0024] ④ Judgment stage: Pipes that exceed the tolerance range are judged as unqualified.

[0025] Damage prevention and buffering mechanism:

[0026] During the movement of the side frame, when the top head contacts the side frame, the spring undergoes elastic deformation under the guidance of the telescopic rod. This design has a protective function:

[0027] Initial contact stage: Spring compression absorbs impact energy, preventing rigid collision between the sealing cover and the pipeline.

[0028] Preferably, in any of the above solutions, the slide block and the side frame are connected by screws, and the bending angle of the side frame is ninety degrees.

[0029] Preferably, in any of the above schemes, the positioning claws are arranged in pairs, and each pair of positioning claws positions one pipe.

[0030] Preferably, in any of the above embodiments, a rubber sealing ring is fixedly connected to the inner side of the sealing cover, and the spring is sleeved on the outside of the telescopic rod.

[0031] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0032] This marine pipeline sealing inspection equipment utilizes a coordinated setup of a back frame, electric cylinder, slide frame, pneumatic cylinder, track, slide base, side frame, positioning claws, sealing cover, interface, central frame, telescopic rod, spring, and top head. Multiple sets of positioning claws are arranged on the frame platform, with each set of two claws clamping one pipeline to be tested. During inspection, the operator simultaneously places multiple pipeline samples in adjacent positioning claw sets. The pneumatic cylinder retracts the inner sealing cover, synchronously clamping both ends of the pipeline to form a closed inspection chamber. A damage-prevention buffer mechanism is implemented: during the movement of the side frame, when the top head contacts the side frame, the spring undergoes elastic deformation under the guidance of the telescopic rod. This design provides protection during the initial contact phase: the spring compression absorbs impact energy, preventing a rigid collision between the sealing cover and the pipeline. Through an innovative pneumatic positioning structure and elastic buffer mechanism, simultaneous inspection of multiple pipelines is achieved.
