Problems solved by technology

However, the land test is very difficult. At present, the conventional submersible lifting system usually only conducts a preliminary no-load test on a simple site in the factory, and then starts a detailed load test at the wharf after subsequent shipment. This test method cannot be completely effective for the product when it leaves the factory. Verification, commissioning and testing after shipment are heavy workload, and sometimes problems even affect the delivery of the whole ship

Embodiment Construction

[0046] The following structural description drawings further describe the specific technical solutions of the present invention.

[0047] as attached figure 1 As shown in the figure, a land test device for a submersible hoisting system of the present invention includes a tooling gantry 1, a guiding tooling 3, a roll drive mechanism 4, a pitch drive mechanism 5, a weight tray 6 and a weight Code 7.

[0048] as attached figure 2 As shown, the tooling gantry 1 is mainly composed of outriggers 101 , beams 102 , a mounting seat 103 for a hoisting system, a base 104 , a gantry bearing 105 , and a gantry pin shaft 106 . The beam 102 and the outriggers 101 are box-shaped structures with reinforcing ring bars and longitudinal bars inside, and the beams 102 and the outriggers 101 are connected by high-strength bolts. The mounting seat 103 of the hanging system is welded on the bottom of the beam 102, and there are two left and right. The bottom bottom plate of the base 104 is conne...

Abstract

The invention provides a land test device and method for a submersible hoisting system, comprising a tooling gantry (1), a guide tooling (3), a roll drive mechanism (4), and a pitch drive mechanism (5). ), a weight tray (6) and a weight (7), the tooling door frame (1) is used to install the submersible hoisting system, and the guide tooling (3) is used to attach the The cable (205) of the submersible hoisting system, the upper end of the pull rod (602) of the weight tray (6) passes through the pull rod installation hole ( 306) and install a crosspiece (603) to hang on the bottom plate (303), and there are multiple weights (7) that can be hung on the weight tray (6) to simulate the mass of the submersible. The onshore test device and method for the submersible hoisting system of the present invention has a roll driving mechanism and a pitching and anti-sway mechanism, which can perfectly simulate the actual working conditions at sea, and is mainly used to verify the function and load capacity of the submersible hoisting system.

Description

technical field [0001] The invention belongs to the technical field of hoisting and deployment of marine engineering equipment, and in particular relates to a land test device and method for a submersible hoisting system. Background technique [0002] Deep-sea science is one of the important directions in the frontier of science. Deep-sea scientific research relies on technical means and equipment support. As a particularly important deep diving equipment, manned submersibles can be used to perform tasks such as underwater investigation, geological exploration, sample collection, pipeline maintenance, and salvage and life-saving. The lifting system is an indispensable part of the manned submersible operation, and its performance greatly affects the performance and safety of the submersible. [0003] Due to the large workload and complex functions of the hoisting system, land tests are generally required. However, the onshore test is difficult. At present, the conventional ...
