Abstract
The invention discloses a gravity compensating line-hanging structure and a levelling method, and belongs to the technical field of road surface engineering machines and construction. The structure comprises a vertical pile arranged between a certain distance, a cross rod arranged on the vertical pile, a sample line arranged on the end part of the cross rod and a levelling sensor with a rocker arm, a probing oscillating rod and a counter weight, wherein the probing oscillating rod of the levelling sensor is arranged below the sample line and contacts the sample line below the sample line. Through the structure and the method, the moment of the counter weight is balanced with the resultant moment of the gravity of the probing oscillating rod and the gravity of the sample line, and the gravity of the probing oscillating rod and the gravity of the sample line are compensated so as to eliminate errors caused by paving basic standards and further improve the quality of road surfaces.
Description
Technical field
The present invention relates to a kind of gravity compensation hanging wire structure and leveling method, belong to field of road engineering machinery and technical field of construction.
Background technology
Planeness is to weigh the important parameter of pavement spread quality, and the method that guarantees planeness generally speaking is to utilize the levelling appearance of hanging wire structure that road surface that paves and line-transect are compared, with reference to the line-transect adjustment state that paves.Traditional hanging wire structure and leveling method are to beat earlier behind the soldier piles fixed transverse rod on soldier piles, and line-transect is fixed on above the cross bar, and line-transect one end is fixed, and the other end is used the stretcher tensioning.The levelling appearance is surveyed fork and is placed on above the line-transect, leans on gravity closely to contact with line-transect.Paver when work levelling appearance is surveyed fork and on line-transect, is slided, according to the shape adjustment of the line-transect state that paves.Owing to receive action of gravity, the line-transect sag bent comes balance fork gravitation energy enough to reduce the pressure of fork to line-transect although on the detection fork counterweight is housed like this, and the error that the line-transect amount of deflection is brought still surpasses 2mm.Therefore, the error that produces as the line-transect of the benchmark that paves has directly had influence on the planeness on road surface, makes that spreading evenness is difficult to further improve again, obstacle the lifting of pavement quality.
Summary of the invention
The technical problem that the present invention will solve provides and a kind ofly can realize gravity compensation, and gravity is dropped to minimum to the influence of line-transect and eliminates the gravity compensation hanging wire structure and the leveling method of line-transect amount of deflection.
In order to solve the problems of the technologies described above; Gravity compensation hanging wire structure of the present invention is included in the soldier piles set up between the certain distance, be arranged on cross bar on the soldier piles, be installed on crossbar end line-transect, be provided with rocking arm, survey the levelling sensor of fork and counterweight, the detection fork of levelling sensor is arranged at the below of line-transect; The levelling sensor is surveyed fork and is contacted with line-transect from the line-transect below.
A kind of leveling method of gravity compensation hanging wire; Whenever squeeze into soldier piles on ground after drawing accurate baseline by construction requirement at a distance from 5～10 meters; With the connector cross bar of packing into, make line-transect walk around crossbar end and tensioning line-transect, adjust the height and position and the locking of cross bar according to the construction absolute altitude of line-transect; Paver is installed the rocking arm of levelling sensor and surveyed fork in back in place in the centre position of two soldier piles; Be arranged on the below of line-transect and contact surveying fork with line-transect; By the threaded adjustment balance position height and position of fork is changed; Measure the line-transect absolute altitude of surveying the fork position simultaneously and recover normal up to this position absolute altitude, the balance position adjustment finishes and uses the nut check counterweight; So far accomplish levelling.
After adopting such structure and leveling method, there has been error, recovered normal by threaded adjustment balance position absolute altitude owing to receive action of gravity line-transect absolute altitude.The rocking arm of levelling appearance is applied the distance of a moment adjustment counterweight and the rotating shaft of levelling appearance; Counterbalance moment and the resultant moment of surveying fork gravity and line-transect gravity are balanced each other; Compensate surveying fork and the suffered gravity of line-transect, corrected the flexible deformation who line-transect is produced owing to gravity effect line-transect is compensated because of the flexible deformation that gravity produces, eliminated the error of bringing by the benchmark that paves; Raising to spreading evenness brings very big help, thereby can further promote pavement quality.

Fig. 2 is the vertical view of gravity compensation hanging wire structure of the present invention.
The specific embodiment
Explain further details below in conjunction with accompanying drawing and the specific embodiment technical scheme to the utility model.
By figure can find out gravity compensation hanging wire structure of the present invention be included in the soldier piles set up between the certain distance, be arranged on cross bar on the soldier piles, be installed on crossbar end line-transect, be provided with rocking arm, survey the levelling sensor of fork and counterweight, the detection fork of levelling sensor is arranged at the below of line-transect; The end that the levelling sensor is surveyed fork contacts with the line-transect bottom surface.
Embodiment of the present invention is:
1, draws by construction requirement and whenever behind the accurate baseline squeeze into soldier piles 9 on ground at a distance from 5～10 meters, with connector 7 cross bar 6 of packing into, with pack in cross bar 6 end grooves below and thread fix of line-transect 5 with pricking.
2, the tensioning line-transect 5, adjust the height of cross bar position line-transect 5 according to the construction absolute altitude, and lock contiguous block and cross bars 6 with screw 8.
3, paver is in place in the centre position of two soldier piles 9, then the rocking arm 3 of levelling sensor 2 is installed with surveying fork 4 as scheming, and will be surveyed the below that fork 4 places line-transect 5.
There has been error in the line-transect that the centre position of back two soldier piles this moment is installed according to above-mentioned steps owing to receive the action of gravity absolute altitude; Rotary threaded; Adjust the position of counterweight 1 by screw thread, measure the line-transect absolute altitude of surveying the fork position simultaneously, recover normal up to this position absolute altitude; The position adjustment of counterweight 1 finishes and with nut check counterweight 1, so far utilizes the method levelling to finish.The principle of its levelling is: the moment that the rocking arm of levelling appearance is applied; Direction with survey the pendulum stalk the stressed moment that produces opposite; This moment makes the detection fork apply power upwards to line-transect, and the distance of adjustment counterweight and the rotating shaft of levelling appearance balances each other counterbalance moment and the resultant moment of surveying fork gravity and line-transect gravity, and detection fork and the suffered gravity of line-transect are compensated; Having corrected the flexible deformation who line-transect is produced owing to gravity effect makes line-transect be compensated because of the flexible deformation that gravity produces; Finish to this hanging wire and adjustment process, device can be realized line-transect is carried out gravity compensation thus, eliminates the line-transect error.
