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 specific technical solutions of the present invention are further described in the accompanying drawings of the structural description below.

[0047] as attached figure 1 As shown, a land test device for a submersible lifting system of the present invention includes a tooling gantry 1, a guide tooling 3, a pan driving mechanism 4, a pitch driving 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 legs 101 , beams 102 , mounting bases 103 for lifting systems, bases 104 , gantry bearings 105 , and gantry pins 106 . The crossbeam 102 and the outrigger 101 are box-shaped structures with reinforcing ring reinforcement and longitudinal reinforcement inside, and the crossbeam 102 and the outrigger 101 are connected by high-strength bolts. The hanging system mounting seat 103 is welded on the bottom of the beam 102, and there are two left and right. A ring of bolts on the lower bottom pl...

Abstract

The invention provides an onshore test device and method for a submersible lifting system, and the device comprises a tool portal (1), a guide tool (3), a rolling drive mechanism (4), a pitching drivemechanism (5), a weight tray (6), and weights (7). The tool portal (1) is used for installing the submersible lifting system. The guide connection tool (3) is used for hanging a mooring rope (205) ofthe submersible lifting system, the upper end of a pull rod (602) of the weight tray (6) penetrates through a pull rod mounting hole (306) in a bottom plate (303) of the guide connection tool (3) andis provided with a cross bar (603) to be hung on the bottom plate (303), and the weights (7) can be hung on the weight tray and is used for simulating the mass of the submersible. According to the land test device and method for the submersible lifting system, the rolling driving mechanism and the pitching oscillation stopping mechanism are arranged, the actual marine working condition can be perfectly simulated, and the land test device and method are mainly applied to verifying the function and load capacity of the submersible lifting 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 of the frontier of science, and deep-sea scientific research relies on technical means and equipment support. As a particularly important deep-diving operation equipment, manned submersibles can be used to perform tasks such as underwater surveys, geological exploration, sample collection, pipeline maintenance, and salvage and lifesaving. The hoisting system is an indispensable part of the operation of the manned submersible, 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 land test is very difficult. At present, ...
