Swivel structure mass balance automatic adjusting system and application thereof

Abstract

The invention belongs to a mass balance adjusting system, and particularly relates to a swivel structure mass balance automatic adjusting system suitable for the swivel process and application of the swivel structure mass balance automatic adjusting system. A swivel structure mass balance automatic adjusting system comprises an action executing mechanism and a control mechanism, the action executing mechanism comprises a water supply tank arranged on a swivel structure, a first counterweight water tank and a second counterweight water tank, the first counterweight water tank and the second counterweight water tank are arranged at the two ends of the swivel structure respectively, and the first counterweight water tank and the second counterweight water tank are communicated with the water supply tank through pipelines and a high-pressure pump respectively; the control mechanism comprises a sensor arranged on the swivel structure, the signal output end of the sensor is connected with the signal input end of a central control device, and the signal output end of the central control device is electrically connected with the control input end of the high-pressure pump. The technical problems that in the prior art, the weighing process is tedious, and the automation degree is low are effectively solved, and the advantages of being short in operation period, high in operation precision, high in automation degree and the like are achieved.

Description

technical field [0001] The invention belongs to a mass balance adjustment system, in particular to an automatic adjustment system for mass balance of a swivel structure in a swivel process and an application thereof. Background technique [0002] With the vigorous development of traffic construction projects in recent years, there are more and more swivels of various iron-related bridges. The swivel technology can not only ensure the safety of engineering construction, but also transform the operation above obstacles into shore or near-ground operations. It can also reduce the impact on traffic, shorten the closure time and reduce construction costs. More and more new bridge projects cross existing highways, railway lines and rivers. In view of the high safety of the swivel method and the small impact on traffic, most of the new span bridges currently use the swivel method. Physical construction. [0003] In order to ensure the safety and stability of the swivel bridge dur...

AI Technical Summary

Problems solved by technology

[0006] 1. The weighing process is cumbersome. It is necessary to judge the initial posture of the beam body first, then arrange the jack, and carry out the counterweight after the weighing is completed. The whole weighing cycle is relatively long

[0007] 2. The degree of automation is low. The weighing process involves judging the attitude of the beam body and the grading operation of the jacking force. Therefore, the experience and qualifications of the weighing personnel are strictly required, and the degree of automation is low. Due to the uncertainty of the personnel, the weighing inaccurate result

[0008] 3. The accuracy is poor. During the weighing process, the grading gradient of the jack is relatively large, and the obtained weighing data often has large deviations, and accurate counterweighting cannot be achieved, thus increasing the risk of unbalanced bridges.

[0009] 4. The human resources are large and the cost is high. The traditional weighing method often involves the handling of jacks in the weighing process. Due to space constraints, manual handling is often used when machines cannot be used, which is laborious and laborious. In addition, reading personnel, Jack operators and commanders have high labor costs and high labor intensity
