Detailed description of the invention
Fig. 1 is the side structure view of the utility model,
Fig. 2 is the top view of the use of the new type.
Appended drawing reference:
1 balanced support, 2 top plate, 3 lower plywood, 4 hinged groove, 5 hinged ball, 6 spherical groove, 7 strut, 8 nut, 9 handwheel, 10 stabilizer blade, 11 pawl
Follow closely 101 upper support, 102 lower support, 103 runner shaft.
Specific embodiment
The structure of the utility model is to have carried out further improvement to existing triangulation frame, such as Fig. 1 and Fig. 2 institute
Show.
Specific structure is the triangular plate for including bilayer, is divided into top plate and lower plywood.The upper side of top plate is set
The component for having measuring instrument fixed can be prominent or indent fixing piece, or dismountable fixing piece.With specific reference to
The fixed form of the measuring instrument used is determined.
The bottom sides of lower plywood are equipped with the hinged groove of indent in angular position, are equipped with hinged shaft, balanced support in hinged groove
Top be equipped with hinged shaft in hinge axis hole and hinged groove and cooperate.Angle between balanced support and lower plywood can be adjusted arbitrarily, hinged shaft
The upper reasonable damped coefficient of setting, realizes that the angle of the two after fixing does not change.Between specific settable the two contact surface
Frictional force is realized.
Balanced support is telescopic structure, and balanced support includes lower support and the top branch that is arranged in inside lower support
Support, upper support are worm structure in the inside of lower support, and the side of lower support is provided with the runner that hole insertion is equipped with handwheel
Axis, runner shaft go deep into the part inside lower support and are equipped with the turbine structure cooperated with the worm screw of lower support.Rotation hand wheel band
Turn wheel shaft rotates, and the turbine rotation on runner shaft drives the inner hole of worm screw rotation and upper support to move up and down, realization top
Support is stretched.
The bottom of balanced support is equipped with the stabilizer blade being hinged and connected, and the bottom sides of stabilizer blade are followed closely equipped with pawl outstanding, and pawl nail is
Taper.Stabilizer blade is the stripe board of rectangle, and the articulated position of stabilizer blade is on the upper surface of one end, the prominent fraising seat of leg surface,
The lower part protrusion of parallel support simultaneously sets hinged shaft in end, reams and cooperates on hinged shaft and fraising seat, realizes being connected for the two.
One corner of upper side of lower plywood is equipped with fixed hinged ball, and the downside position of corresponding top plate is equipped with spherical shape
Groove, hinged ball are placed in inside of spherical groove, and spherical groove diameter is greater than hinged ball, and hinged ball is limited in inside of spherical groove and is not removed.
The another two corner positions of lower plywood and top plate are equipped with strut, and the lower part of strut is equipped with to be connected between flexural pivot and lower plywood, strut
Top be equipped with screw rod, the downside indent of top plate simultaneously sets fixed nut in indent, between strut upper screw and nut
Cooperation, strut surface, which is equipped with, wears handwheel, and the relative level of top plate is realized in the position that rotary supporting rod adjusts strut opposing nut.
Each support leg of the present apparatus, the screw rod of upper support, runner shaft and strut, flexural pivot use metal structure, remaining
Wood materials production can be used, reduce whole weight.
Distance between upper and lower laminate adjusts principle: rotation hand wheel, and strut is driven to rotate, relative rotation between strut and nut,
The height under the nut of strut changes, and adjusts the distance between the top plate and lower plywood of strut position, realizes top plate
Distance with lower plywood in two corner positions adjusts.It is equipped with flexural pivot between top plate and lower plywood, becomes in adjustment strut height
When low, flexural pivot is in the highest point of inside of spherical groove contact spherical groove, and since spherical groove size is greater than flexural pivot, flexural pivot center is perpendicular
Angular deflection occurs for the vertical centerline of straight line and spherical groove, adapts to the angle change of top plate and lower layer's plate.In strut
Effective length when shortening, top plate and lower plywood become smaller in the branch span that shortens, always due to strut and upper layer plate
Angle change occurs between plumbness, the strut and lower plywood, flexural pivot moves on the lower in inside of spherical groove position, flexural pivot position
It sets upper and lower level distance between plates to become larger, realizes the level of top plate.
The present apparatus extends balanced support in use, measuring instrument is placed on top plate, and passes through rotating wheel axis
Adjust the extension elongation of upper support.Stabilizer blade is placed in ground, presses balanced support, and there is taper pawl in stabilizer blade downside, adaptively
The height in face not level state.According to the horizontal observation device in measuring instrument, the length of balanced support is adjusted, two struts of adjustment
Length finally adjusts the measuring instrument on top plate horizontal.
The utility model and the stabilizer blade of ground face contact are followed closely equipped with taper pawl, can be caught in the tunnel ground that stone is accumulated stabilization
Ground, remaining support adapt to the rotation of all directions using hingedly, do not need specially to choose steady ground placement；The branch being equipped with
Support structure adjusts length, although slower compared to the adjustment length speed of friction mode, its stability using turbine and worm
Good, worm and gear has self-locking, will not be due to height change caused by pressing；Smooth fine tuning is carried out equipped with upper and lower laminate,
It is more conducive to operate under the tunnel of insufficient light.
