Abstract

A tripod containing a central rod, telescopic legs with fixing legs, interconnected by ties and crosspieces, a leveling device, characterized in that the central rod is fixed with a ball support in the crosspiece installed in the upper part of the tripod, and elements of the horizontal device in the form of a rotating in the hole the body crosses with a groove interacting with the central rod slider are installed in the lower part of the rod coaxially with the geometric axis of the tripod.

Description

Trenbga

A useful model related to the construction: the efficient7 implementation of the green-light placement and the installation of antennas, for example (L9Lvk tronnnkh borborov security e ал alizatsiai and the same samples яс clearzin for surveys, measurements in geodesy.

Known industrially used treno1 and -shtas jas used in a set with a teodeyatom see. Passport 2T5K, ZT5Sh1 fail PS with. 9-29. Horizontal instruments on a tripod are made by rotating the three lifting screws placed on the theodolite. The axis of the theodolite is set vertically.

To eliminate backlash in the stand, it is necessary to tighten with a wrench T bolts in the head shears, at the ends I vyantno fastened with wooden rods in the upper metal holder. Level adjustment is carried out by lifting screws of the stand,

Directly insufficient stability of the stand regulates the course of the tricked-out shrouds to wrap the shrieks. fixing tribrach springs to the base of the stand.

The disadvantages of this design include the significant torsional force exerted on the tripod head, in particular under the influence of the wind load due to the small shoulder from the axis of rotation of the head to its hinged joint with a heel. Such an effort causes elastic dvoriayatsya in the legs of the shgatyava and elements of the hot-bearing

devices Design disadvantages include additional opera- tions on the backlash of a regular extra-tool, including the installation of a tripod with a theodolite on the ground ..

Umbrella-type tripod constructions are known, see, for example, French application L2560965 PbM 11 / MLZ / 04, No. 637352, PI6 & S 11 / 24.GIOC5 / OJ from them, which is closer in technical essence to the proposed construction is the design claimed in the application f-2560965 France.

This design is a folding tripod with a central guide Zh. fixing racks connected to the mead about (x50th grade, telesišička socks and a recession device, located in the upper part of the tripod on the supporting platform.,

In this design, when a torque is applied to the saddlery form of the tripod, due to the small shoulder from the axis of rotation to the sharscharweg © the connection of the platform with the noses, significant worutai deformation of the vation occurs in the elements of the tripod structure. In addition, npia operation

openings of joints in the elements of the tripod and the leveling device are possible, in particular, the application of forces in the elevation plane.

To carry out high-precision angular measurements, the intrinsic error of the tripod as a result of backlash and elastic deformations should not exceed the accuracy of the measurements of the devices installed on it, the design of the transducer with the smallest intrinsic errors of angular displacements under the influence of internal and operational loads,

Measurement errors during the installation should be minimal; therefore, the requirements for structural rigidity are increased. All movable joints should be made without clearance, if possible with tightness.

To increase the rigidity of the construction and ease of use in the proposed design of an umbrella type with telescopic legs, “fixing STANDS which, by means of ties 0 of the support platform in the form of a cross, are widely connected to the central rod, the leveling device is placed in the central hole of the cross and acts on the support of the horizontal platform using a rigid a rod mounted with a ball joint without backlash in the crosspiece,

Yaavia is transmitted in this consignment to the rail not through the access platform (crosspiece), but on the rigid rod through the elements of the leveling device and rigid ties, which are located in the lower part of the rod “

As a result of withering of the shoulder of the arm from the action of the twisting force to the point of application of the force to the legs, the tripod reduces the force, which acts on the legs at the same acting moment,

The constructive features of the proposed tripod provide

 stiffness, which in combination with the proposed spatial arrangement of the leveling elements guarantees against possible disclosure of joints in the mating surfaces of the structure when applying forces to the tripod.

On fiig, 1 presents the design of the claimed tranoga.

The tripod contains an upper crosspiece I, in which a rigid rod 2 with a ball joint 3 and a socket 4, telescopic legs hingedly connected to the upper crosspiece I and consisting of a stand 5, erased by a base rail 7, ties 8 hingedly connecting the legs to the bottom are installed tarnically, without play. cross 9 in which the housing 10 of the leveling device with a groove II is installed, in which during the leveling the rod 2 moves about the slider 12 of the handle 13,14,15 16 and the screw 17, which is intended for mutual backlash-free fixing of the corresponding tripod elements, Porgy platform 18, the level 19, level 20.

Before installing the tripod, the supporting surface of the platform is cleaned, tamped. During installation, the telescopic legs of the tripod are bred while lowering the screed 8 by sliding along

rod 2 crosses 9 with gororiziruyuschim device to the stop, stick the rods 6 to the required size, making a preliminary
