Description
Technical field
The utility model relates to portable level measurement devices, and tripod water is carried out suitable for various industries measurement process
Heibei provincial opera is whole, use when centering rod vertically adjusts, while the various horizontal and vertical adjustment for being also applied for forestry survey process use.
Background technique
During being measured using special instrument, common measuring instrument has level, theodolite, total station etc.,
These instruments require to be placed in the enterprising enforcement use of tripod, and instrument has higher requirement to horizontal accuracy.Therefore, often
The horizontal process of the instrument adjustment of rule are as follows: place tripod, the pedestal basic horizontal of adjusting triangle frame places instrument, passes through instrument
Device accurate leveling.In addition, the vertical adjustment of various centering rods also mostly uses, user is voluntarily adjusted or observer commands and carries out
Adjustment.
There are problems:
(1) process for adjusting instrument tripod level is very cumbersome, is unfavorable for neophyty operation；
(2) air level used in instrument needs to observe from top to bottom, and the use of time can make troubles；
(3) the vertical Adjustment precision of centering rod is difficult to ensure.
Summary of the invention
1. to solve the problems, such as
The quality of tripod pedestal horizontality adjustment directly influences the speed and precision of instrument adjustment, how to improve three
Corner bracket pedestal Level tune precision and speed then become a major issue of measurement working efficiency；
Centering rod is another important tool in measurement work, and whether centering rod vertically can also seriously affect measurement
Precision and speed.
Therefore, how using a kind of simple device offer reference, it can improve tripod pedestal and level speed, and can
To indicate centering rod vertical extent, then become our the team major issue to be solved.
2. technical solution
Based on the above issues, the scheme of portable level measurement device is inventors herein proposed, the device is vertical by damp type
Instrument, reflection unit, fixed device are constituted；Reflection unit is located at the bottom of damp type vertical collimator；Damp type vertical collimator and reflection fill
Set the lower portion for being respectively positioned on fixed device；Damp type vertical collimator be cylindrical hollow structure, damp type vertical collimator bottom therefrom
The heart is outside, is carved with several concentric round wires, and cylindrical hollow inside configuration has a vertical needle, and needle front end of hanging down is thinner, is used to refer to fill
The horizontality set, tail end connect soft body structure, and soft body structure is fixed on the upper center position of cylindrical hollow inside configuration, hang down
Needle can freely swing in cylindrical hollow structure, and cylindrical hollow inside configuration adds oil-filled shape transparency liquid.
Preferably, damp type vertical collimator is cylindrical hollow structure, is made, is damping of high transparency, resistance to oxidation plastic material
Formula vertical collimator bottom is outside from center, is carved with several concentric round wires；Cylindrical hollow inside configuration has a vertical needle, and main body is not by
It easily corrodes, the big density-metal material that will not be magnetized is made, and needle front end of hanging down is thinner, is used to refer to the horizontal of device
State, tail end connect soft body structure, and soft body structure is fixed on the upper center position of cylindrical hollow inside configuration, and vertical needle can be in column
Freely swing in shape hollow structure, when the smallest round wires in the center that the needle that hangs down is directed toward the concentric round wires in damp type vertical collimator bottom, then
Device is horizontality；Cylindrical hollow inside configuration adds oil-filled shape transparency liquid, and the pendulum of vertical needle in the device can be effectively reduced
Dynamic amplitude and speed, liquid will not generate condensation phenomenon under zero temperature at 30 degree, will not influence the normal work of device.
Preferably, reflection unit is made of prism, and prism is placed in the bottom of damp type vertical collimator, for reflecting damp type
The relative position image of the vertical needle of vertical collimator bottom and concentric round wires.Originally it whether horizontal to observe damp type vertical collimator, need
Observer comes back and looks up damp type vertical collimator bottom, and operation is inconvenient, and after prismatic reflection, light is changed 90
The direction of degree, only the direct-view of needs level can observe whether damp type vertical collimator is horizontal to observer.
Preferably, fixed device, since the portable level measurement device needs for different equipment (tripod, centering
Bar etc.) level status information is provided, therefore, in order to meet the needs of distinct device, and observed convenient for observer, fixed device
It places and fixes with regard to needing to can be carried out under various conditions.Fixer body is a frame structure, by damp type
Vertical collimator and reflection unit are fixed in frame；Fixed device bottom surface is horizontal plane, and has magnetism, can be placed in tripod
The needs such as pedestal adjust horizontal position, and magnetic absorption can prevent measuring device from falling；Observer passes through observation reflection unit
Can very easily adjustment equipment, make its fast leveling.
One piece and the handle of frame level are stretched out in the side of fixed device, and there are the groove of an arc, groove in the outside of handle
Inside there is one layer of soft rubber mat, plays a part of to increase frictional force, groove and frame parallel；Portable level measurement device is used for
When the vertical adjustment of the equipment such as centering rod, the handle of fixed device can be pushed down with hand, can also use specific clip or bandage
Handle and centering rod are clamped or are pinioned, measuring device is fixed on centering rod, is attached to measuring device on centering rod,
Groove can guarantee that measuring device will not place has deflection；Observer can be according to height self, observation habit, arbitrarily
The position of portable level measurement device is placed, in order to observe, and will not influence measurement accuracy.
3. beneficial effect
Portable level measurement device provided by the utility model, its advantages are as follows:
(1) this equipment is combined using damp type vertical collimator and reflection unit, observer by horizontal observation it may determine that
The horizontality of equipment；
(2) this device structure is light and handy, portable, can be placed on various tripods and centering rod and use, and can be effective
Save instrument cost；
(3) this equipment can freely be placed according to the height and use habit of user, improve using for user
Comfort.
