Description
Technical field
This utility model relates to fields of measurement, is specifically related to a kind of from vertical level instrument。
Background technology
The scale measured for the discrepancy in elevation when levelling rod is the measurement of the level, is requisite instrument in the measurement of the level。If levelling rod is not vertical when measurement of the level reading, it tilts staff reading all can be caused bigger than normal in which direction, left and right forwards, backwards, affects measurement of the level precision。At present, usually served as staffman by two personnel during the measurement of the level, make levelling rod be in vertical steady statue by hand steered mode。But practical situation is that one side staffman is it is difficult to ensure that levelling rod is vertical all the time, namely staffman is it is difficult to ensure that in whole leveling process, the hand steered levelling rod of staffman does not shake, once levelling rod run-off the straight or rock, error in leveling will be increased, affect measurement of the level precision。On the other hand, continuous print holds up chi to also increase the working strength and work difficulty holding up chi personnel, chi personnel are held up very easily to produce fatigue to consolidate levelling rod, staffman tired in turn is again it is difficult to ensure that levelling rod is vertical and stable in precise leveling all the time, the vertical state of levelling rod is relatively big on the impact of certainty of measurement, particularly in when using electronic level measurement。And the levelling rod of accurate measurement use is generally higher heavier, artificial righting difficulty is big, poor stability。
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, this utility model provides a kind of from vertical level instrument, simple in construction, stability is strong, it is easy to carry, available hand pulley and strain gauge adjust levelling rod state to tackle different environmental conditions, and accuracy is high, is effectively reduced the labor intensity of operator。
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of from vertical level instrument, including levelling rod and foot pin, also includes from miter square frame；Described include rope, base, support bar, brake sheave, fixed pulley, strain gauge, universal joint and spacing hole from miter square frame；Described support bar is vertically mounted on base, the top of support bar installs one group of equal diameters by support and central point is positioned at the fixed pulley on same level line, the side of bracing frame is rotating is provided with brake sheave, the central point of brake sheave and the central point of one of them fixed pulley are positioned on same plumb line, and the equal diameters of brake sheave and fixed pulley；The opposite side of bracing frame is provided with spacing hole；The one ends wound of described rope is in brake sheave, and the other end walks around fixed pulley successively and vertical is passed down through spacing hole and connects the universal joint greater diameter than spacing hole, and described universal joint is flexibly connected with the top of levelling rod。
The top of described levelling rod is provided with and buckles, and the bottom of universal joint is provided with and buckles the hook being connected。
Described support bar includes fixing bar and movable bar, and described movable bar can move up and down in fixing bar。
Described brake sheave, assembly pulley and spacing hole are installed on movable bar。
Described brake sheave is provided with rocking handle。
Rope between described brake sheave and fixed pulley arranges strain gauge。
Described base is the collapsible base of Y type。
The described collapsible base of Y type can rotate simultaneously within the scope of horizontal plane 360o and vertical direction 180o, is highly convenient for fixing and storage。
Due to the utilization of technique scheme, this utility model compared with prior art has the advantage that
This utility model scheme from vertical level instrument, utilize the deadweight of levelling rod, by parts such as strain gauge, rope, pulleys, levelling rod state can be judged according to strain gauge reading；Pulley is connected with universal joint spacing hole, only allows rope to pass through, and universal joint can not pass through, and levelling rod is connected with rope end by universal joint。Above-mentioned level gauge simple in construction, stability is strong, it is simple to carry, and available hand pulley and strain gauge adjust levelling rod state to tackle different environmental conditions, and accuracy is high, is effectively reduced the labor intensity of operator。
