The alidade portion is coaxially connected onto the base, and the alidade portion and the base can relatively move. The alidade portion comprises a horizontal circle, an altitude circle, a circular water level, a water level pipe, a horizontal clamp screw, a horizontal final motion screw, a vertical clamp screw, a vertical final motion screw and the like. The telescope is connected with the alidade portion through a horizontal shaft of an instrument and can freely rotate around the horizontal shaft, a circular shaft is fixed at the center position of the telescope along the direction vertical to a collimation axis of the telescope and the horizontal shaft of the instrument simultaneously, a circular shaft sleeve is sleeved outside the circular shaft, and the circular shaft sleeve is fixedly connected onto the laser emitter. The laser emitter can rotate around the circular shaft fixed on the telescope through the shaft sleeve. The theodolite can help workers to simply and rapidly mark the waist line on tunnel sides or roadway sides and improve work efficiency.

Description

A kind ofly can conveniently survey the transit of establishing stringcourse

Technical field

The utility model relates to a kind of transit, particularly a kind ofly can conveniently survey the transit of establishing stringcourse.

Background technology

In the process that tunnel and underground engineering construction are built, be correct driving and the perforation that guarantees tunnel and underground passage, the related work personnel need frequent carry out tunnel and tunnel in, the demarcation and the check work of stringcourse.Generally, for increasing work efficiency, in, the staking-out work of stringcourse carries out simultaneously, the staff can utilize pertinent instruments equipment such as transit or total powerstation at first to accomplish the staking-out work of center line; And then on the plumb bob line of centerline, mark the position of stringcourse point with pin, and on center line, mark after the stringcourse position, through the method for drawing horizontal line or calculating pseudo-inclination angle stringcourse point mark is located at the tunnel and helps, so that the driving personnel grasp construction.Wherein, the work that stringcourse point mark is set to tunnel group mentioned above can also be simplified so that increase work efficiency.

This shows that prior art awaits further improving and development.

Summary of the invention

The purpose of the utility model provides a kind ofly can conveniently survey the transit of establishing stringcourse, guaranteeing that stringcourse surveys under the prerequisite of the precision of establishing, simplifies the survey of stringcourse and establishes work, increases work efficiency.

In order to solve the problems of the technologies described above, the scheme of the utility model comprises:

A kind ofly can conveniently survey the transit of establishing stringcourse; It comprises base, alidade, telescope and generating laser; Wherein, Center position is with the cylinder-shaped sleeve of a hollow along simultaneously being fixed with a circular shaft perpendicular to the direction of telescopical collimation axis and alidade transverse axis on the described telescopical mirror outside the circular shaft, and cylinder-shaped sleeve is fixed on the generating laser;

Describedly a kind ofly can conveniently survey the transit of establishing stringcourse, wherein, the optical axis of described generating laser is designed with a sighting device all the time perpendicular to the neutral axis direction that is fixed on the cylinder-shaped sleeve on the generating laser directly over the generating laser;

Describedly a kind ofly can conveniently survey the transit of establishing stringcourse; Wherein, Described generating laser can rotate around the circular shaft that is fixed on the telescope under the effect of external force; And the optical axis of generating laser when telescopical collimation axis places the tunnel to design on the vergence direction at inclination angle, rotates generating laser all the time perpendicular to its turning axle direction; What the light beam of generating laser was inswept at this moment is a dip plane that is parallel to stringcourse, and the intersection that dip plane and tunnel two are helped promptly is a line that parallels with gradeline; Generating laser is provided with a sighting device, so that the observation personnel aim at the direction that need sight.

According to above-mentioned technical scheme, the utility model can help simple, convenient and rapid mark stringcourse of staff to be located at the tunnel or help in the tunnel, and accelerating construction progress is increased work efficiency, and is convenient and practical, is easy to realize, is convenient to promote.

Fig. 2 is by the structure diagram of the union body that telescope and generating laser constituted in the utility model.

Embodiment

More explicit for the purpose, technical scheme and the advantage that make the utility model, will combine accompanying drawing and embodiment that the utility model is explained further details below.

A kind ofly can conveniently survey the transit of establishing stringcourse; Like Fig. 1, shown in Figure 2; It comprises base 1, alidade 2, telescope 3 and generating laser 4; Wherein, thus described base 1 can link to each other with fastening bolt on the tripod through center screw 5 instrument is fixed on the tripod, is connected with alidade 2 on the base 1; Described alidade 2 can rotate with respect to base 1, and it comprises horizontal dial 6, altitude circle 7, circular bubble 8, level tube 9, level braking spiral 10, horizontal final motion screw 11, vertical clamp screw 12, vertical final motion screw 13; Described telescope 3 is fixed together with transverse axis 22; Telescope 3 is provided with eyepiece focusing spiral 20 and object lens focusing screw 21; And on the mirror of telescope 3 center position along simultaneously being fixed with a circular shaft 14 perpendicular to the direction of the transverse axis 22 of the collimation axis of telescope 3 and alidade 2; Circular shaft 14 outsides are with a cylinder-shaped sleeve 15, and cylinder-shaped sleeve 15 can rotate around circular shaft 14, and cylinder-shaped sleeve 15 is fixed on the generating laser 4; Described generating laser 4 can rotate around the circular shaft 14 that is fixed on the telescope 3, and the optical axis of generating laser 4 is all the time perpendicular to its turning axle direction; Described generating laser 4 is provided with a sighting device 16, so that the observation personnel aim at the direction that need sight; One end of described generating laser is designed with a battery cover 19, and the user can screw off the battery that battery cover 19 is changed generating laser 4 inside.

The observation personnel can settle instrument at the centerline place of having demarcated; Adjustment tripod frame leg and foot screw 17; Centering and leveling instrument; Make the bubble of circular bubble 8 and level tube 9 of the utility model strict placed in the middle, the position to the centerline of having demarcated check errorless after, carry out the staking-out work of center line according to pointing to the angle.After having demarcated one group of centerline,, make the telescope 3 of instrument accurately sight the plumb bob line of one group of centerline of firm demarcation through rotating operations such as alidade 2, the level braking spiral 10 of screwing, the horizontal final motion screw 11 of adjusting; Through rotating telescope 3, the vertical clamp screw 12 of screwing, regulating operation such as vertical final motion screw 13, make perpendicular dish 7 readings aim at the design inclination angle in tunnel, this moment, telescope 3 sight lines were parallel with gradeline; Open the switch 18 of generating laser 4 and rotate generating laser 4; In generating laser 4 rotation processes; The intersection of laser beam that it sent and tunnel group is the parallax that is parallel to gradeline; The staff arrives the vertical distance of stringcourse again according to parallax, help in the tunnel to mark design stringcourse position, so that the driving personnel grasp construction.The utility model has been simplified the work of establishing stringcourse with the transit survey, can help the staff to increase work efficiency accelerating construction progress.
