Description

Technical Field

[0001] This utility model relates to the field of container ship repair and construction, and more specifically, to an electric test fixture for container hatch cover seats. Background Technology

[0002] During the construction or repair of container ships, in order to verify the installation accuracy of the container positions and ensure that the container cones and seats meet the requirements of container loading and unloading operations, a container lifting test is usually carried out for completion inspection. This involves using lifting equipment to lift a standard container to simulate the container loading and unloading process, in order to verify the accuracy of the container loading system.

[0003] Crane resources are a core resource for shipyards / repair plants. Section lifting and material handling all require cranes. Container lifting tests consume a significant amount of crane resources, impacting production efficiency. For example, a 300m long 7500TEU container ship has approximately 287 standard 40-foot container slots on the hatch cover, approximately 482 standard 20-foot container slots, and approximately 241 standard 40-foot container slots inside the hold. One self-inspection test and one final inspection test are required. Ignoring the need for retesting after corrections for accuracy deviations, it is estimated that 2020 container slots need to be tested. On average, one hour of crane time can only complete the lifting tests of 10-12 container slots. Assuming 12 tests per hour, at least 168 hours (7 days) of continuous testing would be required, consuming a large amount of crane resources.

[0004] Therefore, it is necessary to propose an electric test fixture for container hatch cover seats to solve the above problems. Utility Model Content

[0005] To overcome at least one of the defects (deficiencies) of the prior art, this utility model provides an electric test fixture for container hatch cover seats.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: an electric test box tooling for a container hatch cover and seat, including a test box bracket, a traveling bracket, a hydraulic lifting mechanism, and a remote-controlled traveling vehicle that can travel on the container hatch cover;

[0007] The traveling bracket is mounted on a remote-controlled traveling vehicle, and the test container bracket is provided with container corners for mutual installation with the container seats on the container hatch cover;

[0008] The test container bracket is jacked up and down on the traveling bracket via a hydraulic lifting mechanism. A remote-controlled traveling vehicle that moves on the container hatch allows the tooling to move on the hatch, thus replacing the forward, backward, left, and right planar movement of a crane. The hydraulic lifting mechanism enables the tooling to rise and fall, simulating the loading action of a crane. Since the test container bracket is a steel structure manufactured to container dimensions, it can replace a standard container to perform container seat accuracy inspection. This invention, through a reasonable structural design, combines the remote-controlled traveling vehicle, the hydraulic lifting mechanism, and the test container bracket, enabling the test container tooling to move from one container position to another on the container hatch without using a crane. This allows for rising and falling movements to simulate loading actions and inspect the container seat accuracy, thereby reducing the use of crane resources for container lifting tests.

[0009] Furthermore, the hydraulic lifting mechanism includes a hydraulic cylinder, a cylinder base, a cylinder connector, a hydraulic pump, a hydraulic distributor, and a hydraulic pump control box;

[0010] The hydraulic cylinder is connected to the test chamber bracket via a cylinder connector, and the cylinder base is connected to the traveling bracket. The hydraulic cylinder is vertically and flexibly mounted inside the cylinder base.

[0011] One end of the hydraulic pump is connected to the hydraulic pump control box, and the other end is connected to the hydraulic cylinder through a hydraulic distributor. The hydraulic pump is driven by the hydraulic pump control box, and then the hydraulic flow is distributed so that multiple cylinder bases can drive the hydraulic cylinders simultaneously, thereby realizing the lifting and lowering control of the test chamber bracket.

[0012] Furthermore, the hydraulic cylinder is equipped with a hydraulic pipe support, which can support the installation of the hydraulic pipe.

[0013] Furthermore, a hydraulic pump protective cover is provided on the outside of the hydraulic pump, which can protect the hydraulic pump.

[0014] Furthermore, the hydraulic pump control box is equipped with a protective cover on its outside, which can protect the hydraulic pump control box.

[0015] Furthermore, a distributor protective cover is provided on the outside of the hydraulic distributor, which can protect the hydraulic distributor.

[0016] Furthermore, the test chamber tray is equipped with a limiter, which can limit the movement of the test chamber tray in the front-back, left-right and right directions.

[0017] Furthermore, the limiter includes front and rear limiters, left and right limiters, and limit baffles;

[0018] The limiting baffle is installed on the test chamber bracket;

[0019] The front and rear limiters are set on the limit baffles in the front and rear directions of the test chamber tray, and the left and right limiters are set on the limit baffles in the left and right directions of the test chamber tray. By setting the front and rear limiters and the left and right limiters on the limit baffles, the movement of the test chamber tray can be limited.

[0020] Furthermore, it also includes a remote-controlled vehicle connector mounted on the traveling bracket. The remote-controlled vehicle is connected to the traveling bracket via the remote-controlled vehicle connector, which facilitates the connection and installation of the remote-controlled vehicle.

[0021] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0022] This utility model discloses an electric test fixture for container hatch covers and seats. A remote-controlled traveling vehicle moves on the container hatch cover, allowing the fixture to move freely and replace the horizontal and vertical movement of a crane. A hydraulic lifting mechanism enables the fixture to rise and fall, simulating the loading action of a crane. Since the test fixture's support frame is a steel structure manufactured to standard container dimensions, it can replace a standard container to perform seat accuracy testing. Through a rational structural design, this utility model combines the remote-controlled traveling vehicle, hydraulic lifting mechanism, and test fixture, enabling the test fixture to move from one container position to another on the container hatch cover without using a crane. This allows for rising and falling movements to simulate loading actions and test the seat's accuracy, thus reducing the use of crane resources for container lifting tests.
