Problems solved by technology
[0003] 1. Dangerous operation: due to the need for personnel to look at the measurement and positioning, sometimes the erection height of the sample box girder is relatively high, and the safety of the operator cannot be guaranteed
[0004] 2. Low level of automation: The erection process requires personnel to participate in the whole process on site, and relies more on manual measurement and observation
[0005] 3. Personnel operation is troublesome and work efficiency is low
[0006] Therefore, a safe and efficient in-position adjustment system is needed to solve the problems of low level of automation, low work efficiency and high risk.

The invention relates to a large sample positioning regulating system. The system comprises two driving positioning sub-systems and two driven positioning sub-systems which are arranged under the fourcorners of a large sample correspondingly. Each driving positioning sub-system comprises a regulation rotary structure, a double-rod hydraulic oil cylinder, two auxiliary oil cylinders, a fixing plate, a moving friction structure and a bottom plate. Each driven positioning sub-system comprises a bottom plate and a regulation rotary structure arranged on the bottom plate. Furthermore, vertical direction self-steering limit mechanisms are mounted on the regulation rotary structures of the driving positioning sub-systems and the driven positioning sub-systems correspondingly. Sand table mechanisms are arranged at the bottoms of the driving positioning sub-systems and the driven positioning sub-systems correspondingly. By means of the large sample positioning regulating system, the sample canbe accurately regulated and positioned, the working efficiency and work safety are improved, and in addition, the automation level of the equipment can be further increased under control of an operating system.
Description
technical field [0001] The invention relates to an in-position adjustment system for large samples, in particular to a fully automatic in-position adjustment system for the precise positioning of large samples (such as box girders) during the erection process, belonging to large-scale sample erection adjustment equipment technology field. Background technique [0002] In the prior art, in order to realize the precise positioning of large sample erection, different types of positioning systems have been designed. The most common equipment and method at present is to directly lift up the four corners of the sample through four jacks. Its working principle is: the staff first measures the general position of the sample with tools, places the sample on the jack, and then adjusts the position of the sample while measuring. This way of working has the following disadvantages: [0003] 1. Dangerous operation: Because personnel are required to watch the measurement and positionin...
