Abstract

The utility model discloses a baseline shift observing board, which comprises a pedestal, a sliding slot arranged on the pedestal, an aiming bracket vertical to the pedestal and capable of sliding along the sliding slot, an indicator fixed on the bottom end of the aiming bracket, a scale corresponding to the indicator arranged on the pedestal, a laser emitter and a reflector plate having an aiming cross, wherein the laser emitter is fixed on the middle part of the aiming bracket; the reflector plate having the aiming cross is fixed on the top end of the aiming bracket; the pedestal is provided with three adjusting screws for adjusting the pedestal to be horizontal; and the pedestal is provided with a round water level. The utility model has the advantages that the three adjusting screws and the round water level arranged on the pedestal can ensure the pedestal to be horizontal and the laser emitter and the reflector plate having the aiming cross can aim accurately, so as to promote the measuring precision, shorten the manual adjusting time and promote the working efficiency.

Description

A kind of baseline shift observation is observed
Technical field
The utility model relates to the device that a kind of auxiliary total powerstation carries out displacement observation, and particularly a kind of baseline shift observation is observed.
Background technology
Collimation line method is one of method of deep basal pit displacement monitoring, and its measuring principle is: the plane of collimation that utilizes total powerstation for perpendicular as benchmark, on collimation line, lay the deformation monitoring point then.Along with the excavation of foundation ditch, deformation monitoring is named a person for a particular job and is moved towards the direction of excavation of foundation pit, and its distance that moves is the displacement of deformation monitoring point.Traditional method is upright survey pin at deformation monitoring point place, regulates the position of survey pin, and survey pin is on the collimation line, utilizes ruler directly to measure the shift value of deformation monitoring point then.But the number reading method of survey pin and ruler exists more error, and the kind of its error mainly contains following several: the first, can not horizontal reading when ruler is put with the ruler face can not the vertical reading error that causes with collimation line; The second, the excessive reading error that causes of the diameter of survey pin; The 3rd, the reading error that the angle of people's eyes and survey pin ruler causes during reading; The 4th, the pointing error during total powerstation aiming survey pin.Owing to there are above all errors, cause the number reading method measuring accuracy of survey pin and ruler not high, can only estimate and read 1mm, and in the process of reading, need to regulate repeatedly the position and vertical degree of survey pin; It is more to expend time in, inefficiency.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of baseline shift observation simple in structure, that measuring accuracy is high to observe.
In order to solve the problems of the technologies described above, baseline shift observation of the present utility model is observed, comprise pedestal, be arranged on chute on the pedestal, perpendicular to pedestal and diopter, the pointer that is fixed on the diopter bottom that can slide along chute, be arranged on the pedestal with the corresponding scale of pointer, generating laser and have the reflector plate that aims at cross, described generating laser is fixed on the middle part of diopter, describedly has a top that the reflector plate that aims at cross is fixed on diopter.
For the level of adjustment pedestal, baseline shift observation of the present utility model is observed, and described pedestal is provided with three and is used to adjust the adjusting bolt that the pedestal level is used.
In order to observe the horizontal situation of pedestal intuitively, baseline shift observation of the present utility model is observed, and described pedestal is provided with a circular bubble.
The beneficial effect that the utility model is obtained is: pedestal is provided with three and regulates bolt and round spirit level, can guarantee the level of pedestal, generating laser and have the reflector plate that aims at cross and can realize accurate aiming, and effect by pointer and rule, improved measuring accuracy, simultaneously, reduce the artificial adjustment time, improved work efficiency.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Among the figure: 1, pedestal, 2, round spirit level, 3, scale, 4, have a reflector plate that aims at cross, 5, diopter,
6, generating laser, 7, pointer, 8, adjust bolt, 9, chute.
Embodiment
As depicted in figs. 1 and 2, baseline shift observation of the present utility model is observed, comprise pedestal 1, be arranged on chute 9 on the pedestal 1, perpendicular to pedestal 1 and diopter 5, the pointer 7 that is fixed on diopter 5 bottoms that can slide along chute 9, be arranged on the pedestal 1 with pointer 7 corresponding scales 3, generating laser 6 and have the reflector plate 4 that aims at cross, described generating laser 6 is fixed on the middle part of diopter 5, describedly has a top that the reflector plate 4 that aims at cross is fixed on diopter 5; Described pedestal 1 is provided with three and is used to adjust the adjusting bolt 8 that pedestal 1 level is used; Described pedestal 1 is provided with a circular bubble 2.
In the time of concrete the use, baseline shift of the present utility model observation observed be adjacent to the deformation observation point, adjust and regulate bolt 8, make that the round spirit level 2 on the pedestal 1 is placed in the middle, thereby guarantee pedestal 1 level, and will this moment pointer 7 over against scale value write down, the laser that sends by generating laser 6 is determined observed ray then, translation diopter 5 more at last, the reflector plate 4 that makes aim at cross having on the diopter 5 is positioned at the telescopical center of total powerstation, at this moment, more right scale values such as pointer 7 is write down, deduct initial scale value with this scale value, be the displacement that is observed.
Baseline shift observation of the present utility model is observed, pedestal 1 can be adjusted to level by three adjusting bolts 8 and round spirit level 2, and the reflector plate 4 that aim at cross having on generating laser 6 and the diopter 5 can guarantee the levels of precision measured, has therefore improved measuring accuracy greatly.
Baseline shift observation of the present utility model is observed, and the adjustment process can once be finished, thereby has improved the work efficiency of adjustment greatly.
