Summary of the invention
Object of the present invention is exactly solve the aforementioned problem utilizing general purpose tool cannot ensure continuous casting segment basic framework installation accuracy, and provides a kind of method measuring continuous casting segment basic framework for this reason.The method is without the need to too many fund input, also without the need to adding the measuring equipment of any costliness, as long as make a simple aid of structure by oneself, existing total powerstation just can be coordinated to measure, thus solve insoluble measuring accuracy problem in the installation of existing continuous casting segment basic framework.
Technical purpose of the present invention is achieved by the following technical programs:
A kind of method measuring continuous casting segment basic framework, comprise a homemade aid, the formation of described aid comprises two major axis be arranged in parallel and four semiaxis be connected with the two ends concentric of two described major axis respectively, also comprise on the major axis that is horizontally installed on described in two relative to two screw rods of the lengthwise centers symmetry of described major axis and respectively it to have gauged distance and two arc notch catering to described major axis cylindrical determine two criterion distance models of the spacing of two described major axis, screw rod described in two is fixed as a rectangular frame respectively by the major axis described in four pairs of double nuts and two.
The step utilizing aforesaid aid to measure continuous casting segment basic framework is:
(1) make four pairs of double nuts in homemade described aid on two screw rods be in respectively and treat locking state, and four semiaxis being connected to two major axis two ends in described aid are placed in respectively need measure the bearing shell of sector segment basic frame one end and the back up pad of the other end on;
(2) make the semiaxis described in four rotate on described bearing shell and back up pad respectively, and utilize frame level respectively the plane of four described semiaxis to be adjusted to level;
(3) determine the standard scale between two major axis with two arc notch two criterion distance models with gauged distance, be then locked respectively by four pairs of double nuts on two screw rods;
(4) prism of total powerstation is placed into respectively on the axis of any three semiaxis in four described semiaxis, utilizes total station survey to go out absolute altitude and the horizontal level of this sector segment basic frame;
(5) repeat each step above, another sector segment basic frame is measured, until the installation of each sector segment basic frame all completes in described continuous casting segment basic framework.
Compared with prior art, its beneficial effect is the inventive method:
(1) buy without the need to dropping into substantial contribution and use expensive overseas equipment and special surveying instrument, thus reducing executive cost;
(2) dimensional measurement of continuous casting segment basic framework can be completed when not possessing high precision special measurement instrument accurately, thus save construction cost, for equipment installs condition of providing convenience;
(3) convenient operation, simple and practical, accurately can ensure for supporting the absolute altitude in each bearing shell axle center and the distance relative to outer arc datum line of fan-shaped section one end on sector segment basic frame, and accurately ensure the absolute altitude of the back up pad for supporting the fan-shaped section other end simultaneously.
Accompanying drawing explanation
Fig. 1 utilizes homemade aid to carry out the floor map measured in the inventive method;
Fig. 2 is the side view of Fig. 1.
Embodiment
In order to make the present invention more easily be understood, below in conjunction with drawings and Examples, its technical scheme is described in detail.
Fig. 1, Fig. 2 illustrate with floor map and side view the method that the present invention utilizes homemade aid to measure some sector segment basic frames respectively.
With reference to Fig. 1, the aid in the inventive method comprises screw rod 1, criterion distance model 2, semiaxis 3 and major axis 4;
Described major axis 4 is two, they be parallel to each other and its two ends be respectively arranged with its with diameter semiaxis 3, four described in semiaxis 3 be connected with described major axis 4 concentric in the mode inserting two described major axis 4 end axis holes respectively;
Described screw rod 1 is two, and they are parallel to each other and are laterally arranged on the major axis 4 described in two respectively by four pairs of double nuts, and the screw rod 1 described in two is symmetrical relative to the lengthwise centers of described major axis 4;
Described criterion distance model 2 is two, they lay respectively at the outside of two described screw rods 1, and it to have gauged distance and two arc notch catering to described major axis 4 cylindrical are determined between two described major axis 4 distance scale, after this distance scale is determined, then by four pairs of double nuts on two described screw rods 1, it is locked, thus make the screw rod 1 described in two and the major axis 4 described in two form a stable rectangular frame, so that the use of total powerstation.
