Abstract
The utility model relates to a laser relay plumbing guiding control positioning rack which belongs to the technical field of measuring instruments, and is characterized in that a positioning steel sheet is provided with more than two positioning holes; two supporting steel sheets are vertically fixed on the positioning steel sheet; a laser fixing shaft is fixed between the two supporting steel sheets by a nut. The laser relay plumbing guiding control positioning rack has the advantages that: 1. the positioning rack has light and flexible structure, is easy to be manufactured, convenient and quick to be installed, can well cooperate with a plumbing method in the relay phase, and is convenient to be used; 2. the positioning rack can be used together with a newly developed method ''laser relay plumbing guiding control'', so that a novel technology can be implemented.
Description
Technical field
The utility model belongs to the surveying instrument technical field.
Background technology
In the hydroelectric project construction, the inclined shaft of steep dip angular length distance is the distinctive buildings of underground run-of-river power station, its primary quality requirements will accurately connect exactly, just seem particularly important as the construction Survey Control of undertaking the anti-ballistic well that connects main task, and this is big, the dangerous strong work of a difficulty.
Through the practice exploitation, method is to adopt the laser locator guiding to control preferably, and present anti-ballistic well construction machinery is generally climbs jar, climb jar and be furnished with cylindrical long tubular laser orientation instrument, and with mounting bracket and steel plate protective cover.But because power station pilot shaft construction environment complexity, for example there is infiltration to form that flue dust in water curtain, the well, exhaust gas concentration are big, long to ventilate under difficult, the combined influences such as laser power is not enough, penetration power deficiency apart from inclined shaft, simple laser guide can not be realized omnidistance control later in long distance, even it is more that ventilation time prolongs, can not solve.
In use often there is following problem in existing laser frame:
1, the locating rack steel plate is bigger, and mass ratio is bigger, and heaviness is installed, carries inconvenient;
2, installation difficulty is big, and original rectangle locating rack is provided with 4 fixed hole positions, and adversary's air drill is very high, careless slightly in the requirement of crag borehole accuracy in the actual installation process, promptly can cause and can't install, and all cancel in the positions, hole, especially task difficulty height in inclined shaft;
3, fault of construction, tubulose laser stationary installation and laser orientation fine motion are regulated bolt and are installed on the fixing steel plate, cross correlation involves many, only can be applicable to the installation of original cylindrical long tubular laser orientation instrument, is not applicable to light laser locator at present.
4, installation difficulty is big, and heavy, thick laser positioning frame and laser locator combination cause the method for laser relay cultellation guiding control to realize, hinder the development and application of advanced method.
Summary of the invention
The purpose of this utility model is:
A kind of laser relay cultellation guiding control locating rack is provided, and it can be in the slope construction of the steep dip angular length distance of hydroelectric project, realizes easy, quick and accurately when carrying out the control of laser relay cultellation guiding.
The technical solution of the utility model is:
Have two above pilot holes on fixing steel plate, two supporting steel plates are vertically fixed on respectively on the fixing steel plate, are fixed with the laser stationary shaft by nut between two supporting steel plates.
The beneficial effects of the utility model are:
1, the present invention's locating rack structure is light, flexible, and manufacture difficulty is little, and simple installation, quick especially in the relay stage, can cooperate the cultellation method well, the convenient use;
2, this locating rack can be well and " control of laser relay cultellation guiding " supporting uses of new method of research and development, makes new technique be entered the practical stage smoothly.
Description of drawings
Fig. 1 is the utility model structure upward view;
Fig. 2 is the utility model structural front view;
Fig. 3 is the utility model structure side view;
Fig. 4 is the utility model working state figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, fixing steel plate, the 2nd, pilot hole, the 3rd, supporting steel plate, the 4th, laser stationary shaft (bolt), the 5th is connected and fixed nut, 6 new pattern laser direction finders (YHJ-800A), the 7th, connects the expansion bolt or the fixing anchor bar, the 8th of crag, laser radiation cover, the 9th, laser beam.
In the selected position that laser locator is installed, at first on crag, the position setting-out of laser locator mounting center is come out by surveying instrument (the perhaps cultellation of upper level laser beam), in view of the above position of positioning hole is emitted mark then at crag;
The pilot hole good to mark carries out bore operation by the hand air drill;
Expansion bolt or anchor pole 7 by suitable diameter are connected the laser positioning frame, fix with crag;
Rotary laser stationary shaft 4, make laser locator 6 laser beam maintenance primary orientation roughly, reach available laser locator 6 inching gear setting ranges, screw attaching nut 5, laser locator 6 is fixedly secured on locating rack, so far change over to survey and establish the fine setting laser stage.
