Problems solved by technology
[0005] 1. Geospatial restrictions
The traditional hydraulic jack calibration method is very unfavorable for the calibration and verification of the prestressed tensioner device in the field, because the field calibration cannot be realized, and the field jacks and oil pumps must be transported to a laboratory with calibration conditions for calibration. The time delay and the data processing of the laboratory calibration will take a certain amount of time, which often leads to work delays
[0006] 2. Low efficiency, unable to achieve fully automatic calibration
The invention solves the problem that the hydraulic jack cannot be calibrated at the construction site, but the structure is complex, the construction cost is high, and the calibration efficiency is low, and the calibration system of this invention adopts an open frame structure on all sides. When the hydraulic jack calibration process fails, It is easy to cause personal injury to the calibration staff

Embodiment Construction
[0044] The technical solutions of the present invention will be described in detail below through embodiments with reference to the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention.
[0045] The term "and / or" in this article is just an association relationship describing associated objects, which means that there may be three relationships, for example, A and / or B, which can mean: A exists alone, B exists alone, and A and B exist simultaneously. In the three cases of B, the term " / and" in this article is to describe another associated object relationship, which means that there can be two relationships, for example, A / and B, which can mean: there is A alone, and there are two cases of A and B alone , In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

The invention relates to a hydraulic jack self-calibration system and self-calibration method, comprising a calibration box, a hydraulic system and a computer, the hydraulic system and the computer are both arranged outside the calibration box, and the hydraulic system communicates with the calibration box through a hydraulic hose The calibration box is connected, the computer is connected with the calibration box through a connecting line, and the hydraulic system includes a hydraulic pump; the calibration box is generally a box-shaped structure with a certain length, and the sides of the calibration box are A baffle groove is symmetrically and evenly arranged on the upper side, and a first side baffle groove is symmetrically and evenly arranged on both ends of the calibration box, and a baffle and a side baffle are arranged in the calibration box, and the two ends of the baffle in the length direction Second side baffle grooves are evenly arranged vertically on the side. The present invention is simple in design, easy to operate, high in calibration efficiency, safe and reliable in the calibration process, low in construction cost and low in maintenance cost, and is suitable for widespread use in a large area of a construction site.
Description
technical field [0001] The invention relates to the field of measurement calibration, in particular to a hydraulic jack self-calibration system and a self-calibration method. Background technique [0002] The jack has the characteristics of large output force, light weight, and long-distance operation. It is equipped with an ultra-high pressure oil pump station, which can realize various forms of operations such as jacking, pushing, pulling, and extrusion. It is widely used in transportation, railways, bridges, shipbuilding and Various industries such as housing development. In recent years, with the rapid development of national construction, especially in the rapid development of high-rise housing development, high-speed rail, and expressways, jacks are very important measuring instruments for measurement in the above-mentioned fields. The quality of jack work is directly related to Quality issues in construction projects. [0003] In actual production, the newly manufac...
