Description
Technical field
This utility model belongs to road survey field, is specifically related to a kind of suspension type laser leveling device.
Background technology
Level gauge is to set up horizontal line of sight based on measurement of the level principle to measure the instrument of the ground point-to-point transmission discrepancy in elevation, and its critical piece has telescope, pipe spirit level, vertical axis, pedestal and foot screw.Level gauge reading is objective, easy and simple to handle, substantially increases precision and the efficiency of the gentle center-post level survey of base in engineering reality, is the most commonly used leveling device of application in current road survey industry, essential during whole Road Alignment Survey Design.
Level gauge in the market mainly has following a few class: tilting level is by mean of micro-one inclining spiral acquisition horizontal line of sight and commonly uses level gauge, half of bubble two ends in bubble observation window is made as coincideing so that leveling difficulty increases, the most long and careless slightly arise that error owing to micro-spiral that inclines will be regulated before each reading.Automatic compensated level is by mean of automatic leveling compensator and obtains a kind of level gauge of horizontal line of sight, and relatively tilting level work efficiency is high, stable accuracy, is usually used in windy and that variations in temperature is big regional operation.Digital level is a kind of level gauge automatically being obtained reading by digital imaging system built-in in instrument.Digital level can be substantially reduced mapping operation labor intensity, it is to avoid artificial subjective reading error, improves certainty of measurement and efficiency.But digital level is highly prone to the impact of light intensity, cause to carry out open work at the high noon (Atmosphere Refraction effect can be produced) of night, cloudy day and sunlight acute irradiation；And for the underground engineering such as tunnel, colliery, more can sunlight or sunlight be not enough, artificial lighting is more weak because of not having, it is difficult to implement the measurement of the level.Laser level is a kind of level gauge utilizing laser beam to replace artificial reading, laser penetration is strong, the characteristic not affected by extraneous light intensity, make it can be normally carried out operation in the exploration environment that sunlight is not enough, artificial lighting is weak such as night, sunlight strong high noon or tunnel, exploration process will not be delayed because of the impact of environmental condition.But, existing laser level is still required for carrying out artificial leveling.
Summary of the invention
The purpose of this utility model is to provide a kind of suspension type laser level so that no matter level gauge can be very easily disposably to carrying out horizontal line location at a distance under which kind of light-intensity conditions.
For achieving the above object, this utility model have employed techniques below scheme:
This laser level includes generating laser, gun sight, spider and the rotatable cantilever being arranged on spider, and described generating laser is suspended on described cantilever, and gun sight is arranged at the bottom of generating laser.
Described laser level also includes the steel wire for hanging generating laser, and one end of described steel wire is connected with described cantilever, and the other end extends below described cantilever along vertical.
The geometric center of described generating laser overlaps with center of gravity, and the other end of described steel wire is fixed on the geometric center of generating laser.
The model of described generating laser is MTO-laserM-33A450-1000-G.
The adjustable in length that described steel wire extends below described cantilever.
It is provided with on described cantilever for adjusting steel wire knob of development length below described cantilever.
The beneficial effects of the utility model are embodied in:
This utility model, by being suspended on cantilever by generating laser, utilizes the deadweight of generating laser itself to carry out leveling, it is to avoid artificial leveling level gauge so that leveling difficulty reduces, and time-consumingly reduces, and precision improves.
Accompanying drawing explanation
Fig. 1 is suspension type laser level overall structure figure described in the utility model；
Fig. 2 is the partial enlarged drawing of Fig. 1；
In figure: 1-generating laser, 2-steel wire, 3-knob, 4-cantilever, 5-spider, 6-gun sight.
Detailed description of the invention
With embodiment, this utility model is elaborated below in conjunction with the accompanying drawings.
, measurement efficiency low, leveling difficulty big problem little for the existing level gauge scope of application, this utility model passes through a generating laser that suspended on 1, make level gauge overcome such as many unfavorable factors such as light intensity on the basis of existing level, more efficiently accurately serve road survey field work.
Seeing Fig. 1 and Fig. 2, suspension type laser level described in the utility model includes spider 5, rotatable cantilever 4, steel wire 2, generating laser 1 and miniature gun sight 6.Described rotatable cantilever 4 is tightened by spiral and is arranged on spider 5, described steel wire 2 top is connected with described cantilever 4 by knob, bottom is then connected with the geometric center (overlapping with center of gravity) of described generating laser 1, generating laser is suspended on cantilever 4, and described miniature gun sight 6 is then placed in bottom generating laser 1.
The using method of above-mentioned suspension type laser level is as follows:
First passing through range estimation selects the position that can see both sides levelling rod to erect spider 5, the height of spider 5 to be determined according to the length of actual topography and geomorphology and used levelling rod, due to gravity straight down, generating laser 1 center of gravity is positioned at its geometric center, steel wire 2 is connected with geometric center, so the laser sent is vertical with steel wire 2 and automatic horizontal.The length simultaneously hanging steel wire is also artificially can to regulate according to practical situation with the knob of steel wire 2 with cantilever 4 junction.
Then generating laser 1 is opened, sighted by miniature gun sight 6, cantilever 4 is made to rotate certain angle, finally cantilever 4 is fixed with the yi word pattern laser rays finding laser transmitter projects to come on levelling rod to be measured for standard, laser owing to launching is automatic horizontal, so avoiding the leveling process of complicated and time consumption.
Finally it is observed reading, i.e. the observation person of both sides water holding object staff, reads the data at this according to the position that the yi word pattern laser rays being incident upon on levelling rod is directed at.(in order to avoid the laser unexpected injury to surveyor, the wearable filter goggle of surveyor)
By using above-mentioned such a technical scheme, during use only need to spider 5 lay appropriate in the case of, generating laser 1 is suspended on spider 5 by cantilever 4, horizontal in-line laser rays can be launched by the generating laser 1 horizontal line to being measured, during construction, only need to directly grasp unified level standard according to horizontal in-line horizontal laser light line, thus solve current level gauge in measuring use, the problem being difficult to position to transverse horizontal line, extremely easy to use, horizontal line registration is reliable.Meanwhile, strong based on laser penetration, the characteristic not affected by light intensity, can use in the external environment of any light intensity, and the shell of this generating laser 1 uses waterproof material, avoids the impact of sleety weather and will not be corroded.Meanwhile, by increasing the rigidity of steel wire 2 and the deadweight of generating laser shell so that it can resist the windage of certain grade, will not the interference of wind-engaging.
In a word, this utility model not only solves the problem of artificial leveling level gauge, and greatly improves measurement efficiency and accuracy of reading.
