Abstract

The utility model discloses a super-elevation plumbing device for measuring the distance. The utility model is characterized in that a sighting board like an arc curved blade is arranged at the top end of a telescopic pull tube, and the sighting board through the processing of the burnishing or electroplating can rotate around a shaft; the pull tube is also provided with pulley wheels which are arranged at the bottom section of rising tubes; pulley wheels are arranged at the upper ends of adjacent outer sleeves, and the upper ends of the adjacent outer sleeves pass through each pulley wheel; a synchronous lifting mechanism is formed by that both ends of the synchronous lifting mechanism are respectively fixed to the spiral ropes at the top end of the secondary outer sleeve; the spiral rope of a hand-operated spiral rope raiser positioned on a parent tube passes by a pulley wheel arranged at the upper end of the parent tube; the symmetrical end of the pulley wheel is fastened at the upper end of the parent tube after the pulley wheels at the bottom ends of the adjacent rising tubes the bottom of the parent tube is also provided with a centering base plate; regulating screws are arranged at the end corners of the centering base plate and a triangle monument mark for centering the cone is arranged at the center of the centering base plate.

Description

Superelevation plumbing device for measuring distance

The utility model provides a kind of range finding superelevation centralising device, and main body is the scalable trombone slide of intussusception, belongs to measuring appliance.

Surveyor's beacon and markstone are tracerse survey and the reference point in topographical surveying.Owing to be subjected to wind and rain etch and artificial destruction all the year round, in a considerable amount of surveys district, these permanent surveying markets are damaged serious.Moreover along with the reinforcement of environmental greening work, the blocking of the setting off of dense trees, groups of building in a compact mass, and adverse condition such as broken country increase a lot of difficulties for the operation of going out of Mapping departments.Set up or study for a second time courses one has flunked permanent installations such as surveyor's beacon, expense is higher, and maintenance difficulties is also big.

The permanent marker difficulty is more at setting up, existing surveyor's beacon and markstone are damaged serious, cause the present situation of a lot of difficulties for the mapping operation, it is a kind of removable that the utility model provides, good stability, in light weight, alignment deviation meets national specifications of surveys requirement, guarantees the range finding superelevation centralising device of operation quality.

The utility model is taked following technical measures, realizes its above-mentioned purpose.

On the trombone slide top of intussusception, setting has through polishing or electroplating processes, the board that pivots of the plate leaf that is convexly curved;

Also has pulley in the trombone slide by the configuration of riser bottom, the pulley of adjacent outer sleeve upper configuration and pass each pulley, two ends are separately fixed at the synchronization lifting mechanism that the twisted rope on time outer tube top is formed, the hinge that is positioned at the hand twisted rope lifter on the parent tube pulley that the parent tube upper end is provided with of restricting, after the pulley of adjacent riser bottom, be fixed on the symmetry end of head sheave on the parent tube;

Also dispose vertex angle part at the bottom of the parent tube and have the adjustment screw rod, the center has the triangle markstone centering substrate of centering circular cone;

When the utility model uses, at first utilize the centering substrate to make its centering, shake hand twisted rope lifter then as required, make sleeve pipe be raised up to required height synchronously, with stay cord it is fixed on the markstone, and makes it vertical.Can survey and draw operation.The surveyor's beacon plate forms a rotation light when wind is arranged, extremely should seek demarcation, has also eliminated the pressure that wind acts on board, and is favourable to maintaining the stability of the apparatus.

Use this device, sleeve pipe can rise to 18 meters as required, and arbitrary height in 18 meters, and below the wind speed level Four, it is measured alignment deviation and is not more than 3mm, meets " national specifications of surveys " requirement.Be applicable to three, fourth class triangle, trilateration and, two polar conductors are measured and topographical surveying.The operation work efficiency can be improved, and operating cost can be reduced.

Accompanying drawing is a structural representation of the present utility model, wherein Fig. 1 is the structural representation of superelevation centralising device, Fig. 2 is an infrared distance measurement superelevation reflecting prism centralising device structural representation, Fig. 3 is the board structural representation, Fig. 4 is the synchronization lifting mechanism structural representation, and Fig. 5 is a centering set square user mode synoptic diagram.Below in conjunction with accompanying drawing, further narrate most preferred embodiment of the present utility model.

Infrared distance measurement superelevation centralising device is made up of synchronization lifting mechanism, euphroe and board in triangle centralising device, the sleeve pipe at the bottom of more piece sleeve pipe, the parent tube.Board (1) surface is through polishing or electroplating processes, and the plate leaf that is convexly curved is fixed on the sleeve, and when wind was arranged, plate leaf and sleeve revolved the central shaft rotation.In the trombone slide, the bottom of riser is provided with pulley (13), adjacent outer sleeve upper road configuration pulley (13), and twisted rope (14) passes pulley (13), and is fixed on time overcoat top.Its twisted rope of hand twisted rope lifter (8) (7) that is provided with on the parent tube passes the pulley of parent tube upper end, after the pulley of adjacent riser bottom, is fixed on the pulley symmetry end of parent tube.Have the end angle at the bottom of the parent tube and be provided with the markstone centering set square of adjusting screw rod, (10) are the centering circular cone of centering set square.(9) adjust handle for horizontal angle.

In the present embodiment, adopt the stay cord reel euphroe that has ratchet shaft.Three leaf arc pallets.

If replace board with reflecting prism (12), fix during use and with 0.5-1 ° of angle of prism declivity, can carry out the infrared distance measurement operation.
