Abstract

The invention discloses a kind of cantilever beam experiment of weighing methods, using " weight transmitting " principle, pass through self-elevating drilling platform cantilever beam rig floor experiment of weighing system, cantilever beam assembly weight is transferred on the weighing-appliance of readable, all data summarizations are weighing results required value, and are compared and draw a conclusion with theoretical value;The advantage of the invention is that:The present invention weighs scheme to JU2000E self-elevating drilling platform cantilever beam systems, is distinctly claimed from requirements such as preparation of construction, equipment requirement and frock makings so that entirely tests convenient, fast, solves the problems, such as in experiment of weighing.

Description

A kind of cantilever beam experiment of weighing method
Technical field
The present invention relates to a kind of weighing methods, and in particular to a kind of cantilever beam experiment of weighing method.
Background technology
After the self-elevating drilling platform construction phase, in order to confirm and examine whether its correlation function meets the requirements, It needs to carry out a series of large-scale experiment, cantilever beam experiment of weighing is exactly one of them.Cantilever beam assembly weight is larger, by outstanding Arm beam sliding system causes cantilever beam assembly overall weight, center of gravity to move, and the center of gravity of entire platform will be made to change, from And make the reaction of bearing redistribution of each spud leg, platform property is produced a very large impact.It can in order to make this influence be maintained at It controls in range, in the design phase it needs to be determined that platform each section distribution of weight, formulates Weight control scheme, and by platform construction side Strict implement.The present invention weighs scheme to JU2000E self-elevating drilling platform cantilever beam systems, from preparation of construction, equipment requirement And the requirements such as frock making are distinctly claimed so that are entirely tested convenient, fast, efficiently solved in experiment of weighing Problem.
Invention content
It is in view of the drawbacks of the prior art and insufficient, it weighs examination the purpose of the present invention is to provide a kind of reasonable design cantilever beam Proved recipe method.
To achieve the above object, the technical solution adopted by the present invention is:A kind of cantilever beam experiment of weighing method, innovative point It is:Using " weight transmitting " principle, by self-elevating drilling platform cantilever beam rig floor experiment of weighing system, by cantilever beam assembly Weight is transferred on the weighing-appliance of readable, and all data summarizations are weighing results required value, and is compared with theoretical value Relatively draw a conclusion;It is as follows:
(1)It in weighing process, introduces synchronization of jacking up, decline technology, avoid single-point stress is excessive from causing equipment or structural failure existing As;
(2)By Modeling Calculation, cantilever beam assembly weight is 3400T, live stress is simulated to each supporting point, to strong to structure Whether degree checking computations meet the requirements, and combine to calculate and determine Jacking point 12, weigh a little 16;According to cantilever beam assembly weight point Cloth has made following deployment:
a)Jacking point:6 600T synchronous effects jack and 6 320T synchronous effect jack, 12 jack Jacking points lead to Synchronous control is crossed, is changed into " three " and puts jacking;
b)It weighs a little:3 600T weight sensors, 4 300T weight sensors and 9 400T weight sensors, visualization are read Number;
(3)Before jacking, the influential structure of institute and equipment need to be removed, and carry out safety prevention measure, and control jack Gap between sensor and cantilever beam structure, it is ensured that jacking, lower section synchronize;
(4)Start to test, jacked up cantilever beam using jack synchronization of jacking up, disengage it from former rectangular structure, arrangement weight passes Backing plate above sensor transfers jack, construction weight is transferred to weight sensor, and record sensor output value and coordinate;
(5)It repeats step three times, if Data duplication is preferable three times, i.e., differs and be no more than between each weighing results and average value 10%, then cantilever beam assembly experiment of weighing terminates.
The present invention has the beneficial effect that:The present invention weighs scheme to JU2000E self-elevating drilling platform cantilever beam systems, from applying The requirements such as working drawing is standby, equipment requirement and frock making are distinctly claimed so that are entirely tested convenient, fast, effectively solved The problem determined in experiment of weighing.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with specific implementation mode pair The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are only to explain the present invention, and It is not used in the restriction present invention.
A kind of cantilever beam experiment of weighing method is bored using " weight transmitting " principle by self-elevating drilling platform cantilever beam Table scale retries check system, and cantilever beam assembly weight is transferred on the weighing-appliance of readable, and all data summarizations are to weigh As a result required value, and be compared and draw a conclusion with theoretical value;It is as follows:
(1)It in weighing process, introduces synchronization of jacking up, decline technology, avoid single-point stress is excessive from causing equipment or structural failure existing As;
(2)By Modeling Calculation, cantilever beam assembly weight is 3400T, live stress is simulated to each supporting point, to strong to structure Whether degree checking computations meet the requirements, and combine to calculate and determine Jacking point 12, weigh a little 16;According to cantilever beam assembly weight point Cloth has made following deployment:
a)Jacking point:6 600T synchronous effects jack and 6 320T synchronous effect jack, 12 jack Jacking points lead to Synchronous control is crossed, is changed into " three " and puts jacking;
b)It weighs a little:3 600T weight sensors, 4 300T weight sensors and 9 400T weight sensors, visualization are read Number;
(3)Before jacking, the influential structure of institute and equipment need to be removed, and carry out safety prevention measure, and control jack Gap between sensor and cantilever beam structure, it is ensured that jacking, lower section synchronize;
(4)Start to test, jacked up cantilever beam using jack synchronization of jacking up, disengage it from former rectangular structure, arrangement weight passes Backing plate above sensor transfers jack, construction weight is transferred to weight sensor, and record sensor output value and coordinate;
(5)It repeats step three times, if Data duplication is preferable three times, i.e., differs and be no more than between each weighing results and average value 10%, then cantilever beam assembly experiment of weighing terminates.
The present invention weighs scheme to JU2000E self-elevating drilling platform cantilever beam systems, from preparation of construction, equipment requirement with And the requirements such as frock making are distinctly claimed so that are entirely tested convenient, fast, efficiently solved the difficulty in experiment of weighing Topic.
The above is merely illustrative of the technical solution of the present invention and unrestricted, and those of ordinary skill in the art are to this hair The other modifications or equivalent replacement that bright technical solution is made, as long as it does not depart from the spirit and scope of the technical scheme of the present invention, It is intended to be within the scope of the claims of the invention.
