The exploitation of marine oil and gas resource need be arranged the offshore platform of some at sea.Offshore platform mainly contains two types: stationary platform, floating platform.
The marine oil stationary platform generally comprises: upper chunk and fixed support structure under water.This type of offshore platform generally be with upper chunk and under water fixed support structure build separately on land, and adopt floating holder method to carry out marine installation exercise.In the shipping process of large-scale upper chunk, need between its underpart and ship deck, arrange the lower support structure usually.For floating platform, form by upper chunk and bottom buoyancy aid as the one of which, before Qi Xiashui, need in the place usually or group that dock is accomplished its upper chunk and bottom buoyancy aid to working.
For the construction of offshore platform, traditional handicraft generally is first with prefabricated completion of substructure such as lower support structure, bottom buoyancy aids, then, proceeds the construction of upper chunk again.In the building course, upper chunk needs to promote earlier certain height, so that make substructures such as lower support structure, bottom buoyancy aid can insert or be transported to the bottom of upper chunk smoothly.Therefore, the lifting of upper chunk is the important ring in the whole offshore platform assembling process, directly has influence on the construction period and the production cost of offshore platform.
At present, the continuous Lifting System ability of large-tonnage upper chunk has reached 35000 tons, and hoisting depth is 60 meters.Because the tonnage of upper chunk is bigger, hoisting depth is higher, and the activity duration is longer, and is therefore high to the reliable working performance property requirement of upper chunk elevator system.If directly promote operation, the potential risks that exist of elevator system operation are difficult for finding that this just required before the elevator system actual job, need its serviceability is tested, and whether reach requirement to test its working index.
Summary of the invention
Fundamental purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and the test unit of the continuous elevator system of a kind of large-tonnage upper chunk is provided, and it can check many suspension centres of elevator system to promote performance synchronously; And, revise limited element calculation model, thereby instruct the design of actual elevator system better according to the stressed measured value of each parts of test unit and the comparative result of calculated value; Simultaneously, can fully reflect the motion response of elevator system under various situation, solve and utilized the test battery device to simulate the problem that elevator system promotes upper chunk fully through simulation test; For the function feasibility of elevator system and the security of himself provide foundation, reduced the potential risk of elevator system operation, the further further investigation of elevator system is had directive significance.
The objective of the invention is to realize by following technical scheme:
The test unit of the continuous elevator system of a kind of large-tonnage upper chunk is characterized in that: comprise two bases, pylon, tiltedly draw support, cat head beam, hydraulic rockshaft, middle chunk, counterweight, wherein, two bases are the symmetrical expression layout and are placed on the ground; Be separately installed with pylon on the base and tiltedly draw support, and pylon is an one with tiltedly drawing support and connection that the top of pylon is equipped with the cat head beam, the cat head beam is provided with several boss; Hydraulic rockshaft is installed on the boss, and hydraulic rockshaft links to each other with computing machine; The steel strand wires that are positioned at the hydraulic rockshaft lower end are fixed on the middle chunk, lay the balancing weight of Different Weight above the middle chunk.
Said base steel-structure box body.
Said tiltedly drawing is supported for truss structure.
Said cat head beam is the steel-structure box body.
Said computing machine links to each other with sound attitude strain testing appearance, and sound attitude strain testing appearance links to each other with foil gauge, and foil gauge is attached to elevator system measuring point place in advance.
Beneficial effect of the present invention: the present invention can check many suspension centres of elevator system to promote performance synchronously; And, revise limited element calculation model, thereby instruct the design of actual elevator system better according to the stressed measured value of each parts of test unit and the comparative result of calculated value; Simultaneously, can fully reflect the motion response of elevator system under various operating modes, solve and utilized the test battery device to simulate the problem that elevator system promotes upper chunk fully through simulated experiment; For the function feasibility of elevator system and the security of himself provide foundation, reduced the potential risk of elevator system operation, the further further investigation of elevator system is had directive significance.
