In the use, through the setting of pivot 7 and first nut 9 for screw rod 2 can rotate and drive fixing base 1 and produce the displacement of vertical direction, thereby can be more nimble with accurate height of adjusting the support frame.

The coarse adjustment assembly comprises ear seats 10 and supporting legs with adjustable lengths, the ear seats 10 are fixedly connected to the outer side face of the first nut 9, the number of the ear seats 10 is 3, and the ear seats are uniformly distributed in the circumferential direction of the first nut 9. The supporting leg includes first supporting leg 11 and second supporting leg 14, is provided with the pivot on the ear seat 10, is provided with the through-hole on the first supporting leg 11, thereby this pivot is worn to establish and is connected in the through-hole rotation between first supporting leg 11 and the ear seat 10 of realization. The first supporting leg 11 is a hollow rod, one end of the first supporting leg, which is close to the second supporting leg 14, is open, and the second supporting leg 14 penetrates through the first supporting leg 11. First supporting leg 11 and second supporting leg 14 one side are the running through of equidistance linear array and have seted up a plurality of screw 12, one side of first supporting leg 11 is equipped with the bolt 13 that is located screw 12, a pot head of bolt 13 is equipped with second nut 15, when needs adjust the support frame height, can cooperate first supporting leg 11 and second supporting leg 14 to stretch out and draw back, thereby adjust the length of second supporting leg 14 in first supporting leg 11 to suitable height, when debugging the height that needs, insert bolt 13 and fix in the screw 12 of seting up on first supporting leg 11 and the second supporting leg 14, simultaneously the staff can be with bolt 13 dismantlement down take off second supporting leg 14, accomodate first supporting leg 11 through ear seat 10, make the support frame can carry out fast loading and unloading, make things convenient for personnel to carry, promote and use the portability.

Fixed subassembly, including the support base 18 of fixed connection in the bottom of second supporting leg 14, support base 18 bottom fixedly connected with a plurality of toper dead lever 19, the outer lane of a plurality of toper dead lever 19 is circumference array distribution and is provided with a plurality of barbs 20, through the setting of toper dead lever 19 with barb 20, fixes on some complicated topography ground when making things convenient for personnel to use the surveying instrument support frame, and the measurement of keeping stable.

As shown in fig. 4, a cavity is arranged inside the conical fixing rod 19, a motor 21 is arranged in the middle of the bottom end of the cavity, an output end of the motor 21 is connected with a rotating rod 22, a plurality of groups of pressing rods 23 which are uniformly distributed in an annular shape are arranged on the side wall of the rotating rod 22 along the axial direction of the rotating rod, a plurality of groups of sliding holes 24 matched with the pressing rods 23 are arranged on the side wall of the conical fixing rod 19 along the axial direction of the conical fixing rod, the barb 20 is slidably arranged inside the sliding hole 24, a limiting groove 25 is arranged on the side wall of the sliding hole 24, the outer end of the barb 20 at the position of the limiting groove 25 is connected with a limiting block 26, the inner end of the barb 20 is arranged to be an arc-shaped surface, a traction rope 27 is connected between the inner end of the barb 20 and the rotating rod 22, and when the pressing rod 23 rotates, the barb 20 can slide out of the sliding hole 24 by extruding the arc-shaped surface of the barb 20; when the carriage carries out the use in the comparatively soft position of soil, can utilize the toper portion of toper dead lever 19 bottom to insert inside the soil, motor 21 work afterwards, it is specific, motor 21 can be for the servo motor 21 that can just reverse, make bull stick 22 drive depression bar 23 when rotating and be close to barb 20 direction respectively, and after the arc face contact extrusion with barb 20 inner, press barb 20 inside the soil from slide hole 24, thereby can make the support frame more stable fixed, reduce the condition that the support frame tumbled under the interference of wind-force or external force, after the support frame work finishes, motor 21 reverses this moment, and drive depression bar 23 no longer extrude barb 20, also can be through the mode of roll-up haulage rope 27 simultaneously, draw barb 20 inside slide hole 24 again, be convenient for toper dead lever 19 extracts from the soil, stopper 26 and the spacing groove 25 that set up simultaneously also can carry on spacingly to barb 20's position, reduce the condition that barb 20 slided into the cavity under the pulling force of haulage rope 27.

The working principle of the invention is as follows: when the support frame is used by personnel, the support plate 4 is pulled away, the surveying instrument is installed on the support plate 2, the extension spring 8 is installed in the sliding groove 5, and the extension spring 8 contracts to enable the two sliding blocks 16 to be close to each other and drive the support plate 4 installed at the tops of the sliding blocks 16 to fix the surveying instrument, so that the surveying instruments of different types and sizes can be fixed, and the use flexibility of the support frame is improved; when meetting the high production change that needs the observation, personnel's accessible rotates and changes handle 17, drives screw rod 2 and rotates, makes fixing base 1 produce vertical displacement and then adjusts the height of support frame simultaneously. When the height of needs big amplitude adjustment, can cooperate first supporting leg 11 and second supporting leg 14 to stretch out and draw back, when debugging to the height that needs, insert bolt 13 and fix in screw 12 that sets up on first supporting leg 11 and the second supporting leg 14 to the adjustment support frame height. When the carriage is used in the position that soil is comparatively soft, can utilize the toper portion of toper dead lever 19 bottom to insert inside soil, motor 21 work afterwards, motor 21 corotation, make bull stick 22 drive depression bar 23 when rotating be close to barb 20 direction respectively, and with the inner arcwall face contact extrusion back of barb 20, press barb 20 into inside soil from slide opening 24, thereby can make the support frame more stable fixed, reduce the condition that the carriage tumbles under the interference of wind-force or external force, after the support frame work finishes, motor 21 reversal this moment, and drive depression bar 23 no longer extrudees barb 20, also can be through the mode of roll-up haulage rope 27 simultaneously, draw barb 20 into slide opening 24 inside again, be convenient for toper dead lever 19 extracts from soil.

The support frame can effectively help personnel to adjust and fix the surveying instrument, avoids the phenomenon that the existing support frame cannot be adjusted and adapted to surveying instruments of different types and sizes under the influence of a single specification, and simultaneously improves the portability and flexibility of the support frame in use.
