Description

Precise levelling rod perpendicular positioning device

The utility model relates to the surveying instrument instrument that topographic mapping and engineering survey are used, and is specifically relevant with the used instrument tool of measurement of the level.

Current in the measurement of higher degree of topographic mapping and engineering survey, mostly adopt the method for measurement of the level to carry out, the levelling pole that its measurement of the level is used owing to be not equipped with the special chi device of holding, can only come perpendicular positioning with tapeman's both hands and eyes.Like this, it is more arduous, tired easily on the one hand to be that the tapeman holds chi; Be hand steered watching on the other hand, be difficult to keep the stable and upright of blade, the precision of influence measurement, especially for precise leveling, the problems referred to above can not be allowed often.

The utility model mainly comprises connector, pedestal inserting column, elasticity bolt, clamping plate and circle leveling bubble.Connector has a rectangle box body, and box body is stamped lid or does not have lid.Going to the bottom of one of box body a round base inserting column is housed, its shape size is complementary with the shape size of the center hub of the tribrach of general surveyor's transit or spirit-leveling instrument, and it just is inserted in the tribrach of the surveyor's transit of general connection tripod or spirit-leveling instrument during operation.Other end at the box body of connector is connected with a clip slot, and clip slot is presented down vertical channel-section steel shape, its opening outwardly, and A/F should be greater than the levelling pole width; On its side plate elasticity bolt is housed, this bolt screws in the clip slot and connects clamping plate.On the clip slot of connector or other position be equipped with one the circle leveling bubble.In addition, levelling pole centering is located for convenience, upper topside central authorities at clip slot left and right sides plate respectively have one " V " v notch v, and is furnished with catch fitting, it is made up of backstay, vertical line and plumb bob, during " centering " operation, plumb bob is hung on the backstay by vertical line, and backstay places " V " v notch v of clip slot left and right sides plate upper topside central authorities.

The utlity model has following advantage: 1,, exempted the tapeman and held up the operation of chi arduous by hand owing to adopt clip slot to cooperate tripod to come the clamping levelling pole; 2, because the strictness of clip slot clamping levelling pole energy keeps blade vertical and stable, can improve the precision of measurement of the level, thereby the quality of achievement is measured in assurance and raising, this has more significance for precise leveling.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

Fig. 1 structural representation of facing of the present utility model

Fig. 2 plan structure synoptic diagram of the present utility model

Fig. 3 catch fitting structural representation of the present utility model

Among the figure: 1, the lid 6 of the box body 5 of tripod 2, tribrach 3, pedestal inserting column 4, connector, connector, screw 7, circle leveling bubble 8 " V " v notch v 9, clip slot 10,11 elasticity bolts 12 of connector, levelling pole 13, clamping plate 14, backstay 15, vertical line 16, plumb bob

As depicted in figs. 1 and 2, the utility model mainly comprises connector 4,5,9, pedestal inserting column 3, elasticity bolt 10,11, clamping plate 13 and circle leveling bubble 7.Connector has a rectangle box body 4, and box body can have lid or uncovered, and present embodiment has lid 5.Going to the bottom of 4 one of box bodys a round base inserting column 3 is housed, it is fixedly connected on the box plate by screw 6; The shape of pedestal inserting column 3 size is complementary with the shape size of the center hub of the tribrach 2 of general surveyor's transit or spirit-leveling instrument, and it just is inserted in the tribrach 2 of the measurement longitude and latitude of general connection tripod 1 or spirit-leveling instrument during operation.Other end at the box body 4 of connector is connected with a clip slot 9, and clip slot 9 is presented down vertical channel-section steel shape, its opening outwardly, and A/F should be greater than the width of levelling pole 12; Two elasticity bolts 10 and 11 up and down are housed on its side plate, and this two elasticity bolt screws in the clip slot 9 and is connecting clamping plate 13; Observation is during operation, and elasticity bolt promotes clamping plate 13 and clamps levelling pole 12 and make it stable and stand on the tested leveling point.On the clip slot lamina mediana that connects body, round leveling bubble 7 is housed.In addition, levelling pole centering is located for convenience, upper topside central authorities at the left and right sides of clip slot 9 plate respectively have " V " v notch v 8, and is furnished with catch fitting, as shown in Figure 3, it is made up of backstay 14, vertical line 15 and plumb bob 16, when carrying out " centering " operation before the observation operation, plumb bob 16 is hung on the backstay by vertical line 15, backstay 14 places " V " v notch v 8 of the upper topside central authorities of clip slot left and right sides plate, take off catch fitting after the centering operation is finished and again levelling pole 12 is sandwiched in the clip slot 9, carry out level observation operation.
