Embodiment

[0035] Please refer to figure 1 As shown, the present invention provides a simple and quick inspection device for a load test of a balance beam for ships, including a tooling piece 4, the tooling piece 4 is composed of a support frame and a tooling bar, one end of the tooling bar and the support frame are hingedly fixed, and the tooling bar is hinged and fixed. A base 1 is arranged below the other end, a jack 3 is arranged at the top of the base 1, a pressure gauge 2 is arranged at the bottom of the jack 3, the top of the jack 3 is in contact with the bottom of the end of the tooling bar, and a shackle 6 is arranged on the tooling bar. 6 is provided with a wire rope 5 for connecting the balance beam.

[0036] A method of using a simple and quick inspection device for ship balance beam load test:

[0037] S1. Check the UT inspection report of the balance beam weld to confirm whether the tensile test can be performed;

[0038] S2. Move the balance beam to the designated test s...

Abstract

The invention discloses a ship balance beam load test simple and rapid inspection device and a use method thereof.The ship balance beam load test simple and rapid inspection device comprises a tool piece, the tool piece is composed of a supporting frame and a tool lever, one end of the tool lever is hinged and fixed to the supporting frame, a base is arranged below the other end of the tool lever, and a jack is arranged at the top end of the base; a pressure gauge is arranged at the bottom of the jack, the top end of the jack makes contact with the bottom of the tail end of the tool lever, a shackle is arranged on the tool lever, and a steel wire rope used for being connected with the balance beam is arranged on the shackle. The stress condition and size of a main hoisting pipe in the hoisting process are simulated through a tool, the stress of a steel wire rope reaches an actual axial tension value through jacking of a jack, the strain of a main stress component is detected through a stress simulation test, and the actual stress and allowable stress of the structure are compared through conversion. The special requirements of the load test on tools and test sites are effectively avoided, and the test time and cost are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of balance beam inspection, in particular to a simple and quick inspection device for a ship balance beam load test and a method for using the same. Background technique [0002] According to the requirements of the national standard or the regulations of various classification societies, the hoisting balance beam should be subjected to a load test of 1.25 times the design load after the production is completed to check the reliability and safety of the hoisting balance beam. The domestic conventional practice is to simulate the real hoisting. Lift the counterweight 1.25 times the design load, and then use a large crane or gantry crane to hoist the balance beam and counterweight to meet the requirements of the load test and check the safety of the balance beam; [0003] The current inspection method requires large cranes, counterweights, specific requirements for test sites and tools, and has large test limi...
