Description
Technical Field
The utility model relates to a hydraulic engineering metallic structure installs technical field, in particular to open V-arrangement or X shape groove metallic structure equipment coordinate measuring auxiliary device.
Background
At present, in the hydroelectric engineering at home and abroad, the metal structure equipment needs to be measured and placed before the installation of the metal structure, the measurement needs to be carried out when the installation is finished and the acceptance is checked, and the measurement accuracy has great influence on the installation quality of the metal structure equipment. At present, the construction trend of the hydropower station is biased to high water head and high power, the sizes of metal structure embedded parts of corresponding matched metal structures such as pressure steel pipes, volutes, tail water elbows and the like are larger and larger, and the safety risk is higher and higher. As shown in fig. 1, the installation of the metallic structure 1 of the hydroelectric power station is generally adjusted and installed by measuring the coordinate marks of the base point 1.1. At present, the mounting and measurement of a metal structure of a hydropower station generally adopts a small prism as a forward-looking measurement method for observation, and the method needs forward-looking personnel to hold the small prism to a corresponding measurement base point (hereinafter referred to as a hand-holding method) of the metal structure for measurement. Meanwhile, in order to facilitate subsequent welding construction during field installation, welding grooves are formed in the process of manufacturing the metal structural member. The coordinate data of the base point used in the installation process is calculated according to the situation that the groove is not formed on the metal structure on the design drawing, so that when the hand-held method is used for measurement, the measured coordinate data needs to be converted into the actual installation coordinate data corresponding to the situation that the groove is not formed according to the size of the groove, and the actual installation coordinate data can be compared with the design coordinate data of the base point. Therefore, the method has the defects of large accidental error, high safety risk, limited application and measurement space, low construction efficiency and the like, is relatively laggard, and cannot adapt to the current new safe production situation.
Disclosure of Invention
The to-be-solved problem of the utility model is exactly to above not enough and provide a simple structure, on-the-spot installation convenient operation, factor of safety is high a metallic structure coordinate measuring's auxiliary device. The technical scheme is as follows:
the novel auxiliary support comprises an auxiliary support, support scale marks are arranged on the center line of the outer surface of the auxiliary support, the auxiliary support is an L-type metal sheet with long edges and short edges, a light reflecting sheet is bonded on the outer surface of the short edge of the auxiliary support, warp-direction scale marks and weft-direction scale marks are arranged on the light reflecting sheet, the weft-direction scale marks coincide with the support scale marks, and the warp-direction scale marks coincide with the critical edges of the long edges and the short edges of the auxiliary support.
The thickness of the auxiliary support is 0.3-0.5 mm.
The width of the auxiliary support is consistent with that of the light reflecting sheet.
The length of the short side of the auxiliary support is 10-20 mm longer than that of the reflector plate.
The length of the long edge of the auxiliary support is 80-120 mm.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. this auxiliary device can arrange in advance on metal structure before metal structure installs, need not the measurement personnel and stands and carry out the foresight observation on metal structure, has reduced measuring platform and has set up the input and personnel input, has improved measurement personnel's security greatly, has reduced the construction cost input.
2. The auxiliary device has the advantages of simple structure, low manufacturing difficulty and simple and convenient use, and saves a large amount of measuring instrument investment and measuring material investment.
3. The auxiliary device has high degree of reduction of the butt metal structure groove, effectively improves the measurement precision, improves the installation quality, greatly reduces the measurement time, and effectively shortens the construction period.
