Description
Technical field
The utility model relates to the suspension detection technique field of concrete box girder handling equipment, particularly relates to a kind of suspension height measurement mechanism.
Background technology
The high ferro construction generally adopts multiaxis line, hydraulic suspension load bearing equipment to transport with concrete box girder.Advantages such as this equipment has the load-bearing capacity height, and grounding pressure is little, anchorage force is even.But hydraulic suspension keeps 3 flat bearings through dividing into groups in the guard box beam transportation in addition, thereby has effectively avoided transportation raising middle flask torsion beam suspension guard box safety beam.Because axis is many, physical dimension is big, and how keeping in the lifting process level before and after the equipment is one of this equipment key technical problem that need solve.
The concrete box girder handling equipment generally adopts hydraulic suspension to carry balancing equipment stressed; Realize the complete machine height control simultaneously; Need height detecting device in the complete machine height adjustment process and come acquired signal to feed back to the upper strata controller, to judge whether leveling of car load.
Existing equipment generally adopts electronic ruler as the instrument of measuring suspension height, and is as shown in Figure 1, and electronic ruler 2 two ends are separately fixed on hanger bracket 1 and the balance arm on 3, and under the jacking effect of hanging oil cylinder, electronic ruler is flexible together along with hanger bracket 1 goes up and down.On the hanger bracket 1 of four jiaos of complete machines, electronic ruler 2 is installed respectively, through comparing the value of feedback of four position electronic rulers 2, just can be adjusted the height of each group suspension, thereby realize the car load leveling.
Though it is simple to adopt electronic ruler to measure suspension lifting height mounting structure, because in the suspension lifting process, balance arm 3 is with respect to hanger bracket 1; Except moving up and down; Also can rotate around pin joint, this just causes electronic ruler stressed except axial force, also can bear the radial force of side direction; So electronic ruler fractures in lifting process easily, thereby cause the adjustable height measuring ability malfunctioning.
In addition, also adopt ultrasonic range finder to detect the adjustable height of suspension at present in the prior art, still owing to reasons such as the Uneven road or the gradients, can there be distortion in testing result, can not accurately reflect actual conditions.
The utility model content
The utility model provides a kind of suspension height measurement mechanism, exists suspension height to detect distortion or malfunctioning problem in the prior art in order to solve.
For reaching above-mentioned purpose, the utility model provides a kind of suspension height measurement mechanism, and said device comprises angular transducer and linkage assembly; Said angular transducer is installed on the hanger bracket; Said linkage assembly is installed on the balance arm; The output terminal of said angular transducer is connected with said linkage assembly.
Wherein, said linkage assembly comprises driving lever and pull bar, and an end of said driving lever links to each other with the output terminal of said angular transducer, and the other end links to each other with an end of said pull bar, and the other end of said pull bar is fixed on the said balance arm.
Wherein, said angular transducer is installed in said hanger bracket inboard.
Wherein, each pin joint of said device is inlaid with sliding sleeve.
The utility model beneficial effect is following:
The utility model detects the rotational angle of balance arm, and then is converted into suspension height through angular transducer and linkage assembly, can accurately detect suspension height, and has advantage simple in structure, that the life-span is long.
Description of drawings
Fig. 1 is the structural representation of suspension height measurement mechanism in the prior art;
Fig. 2 is the scheme of installation of suspension height measurement mechanism among the utility model embodiment;
Fig. 3 is the scheme of installation of the angular transducer of suspension height measurement mechanism among the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, does not limit the utility model.
Like Fig. 2, shown in 3, the utility model relates to a kind of suspension height measurement mechanism, comprises angular transducer and linkage assembly; Angular transducer 8 is used with linkage assembly, realizes the detection to the suspension lifting height.Angular transducer 8 is installed on the hanger bracket with sensor wrap 4, and the output terminal of angular transducer 8 is connected with linkage assembly, and linkage assembly is installed on the balance arm.Linkage assembly comprises driving lever 5 and pull bar 6, and an end of driving lever 5 links to each other through holding screw 7 with the output terminal of angular transducer 8, and the other end of driving lever 5 links to each other with an end of pull bar 6, and the other end of pull bar 6 is fixed on the balance arm.Detailed calculated all need be passed through in the home position of angular transducer 8 and the fixed position of pull bar 6 on balance arm, makes the rotational angle of sensor can be converted into the up-down displacement of suspension accurately.Because this conversion belongs to basic mathematical problem, and relevant with the radii size and the corner dimension between hanger bracket and the balance beam of the length of driving lever, connecting rod, angular transducer 8, present embodiment is not being described in detail.
Angular transducer 8 is installed near the inboard line of symmetry of hanger bracket, plays the effect that effective protection angular transducer is not damaged.Put on the driving lever 5, connecting rod 6 underlyings, driving lever 5 end holding screws 7 fixing this mechanism driving levers 5 with suspension lifting time that can guarantee do not break away from angular transducer 8.Each pin joint is inlayed sliding sleeve, guarantees that mechanism rotates flexibly.
In the suspension lifting process, pull bar 6 moves with balance arm and then drives driving lever 5 motions, and driving lever 5 motions drive the sensor output terminal again and rotate, so sensor obtains angular signal.This signal is uploaded to the upper strata controller, is converted to shift value through angle value after resolving computing, thereby obtains the adjustable height of suspension.Carry out the suspension height adjustment after the upper strata controller compares this shift value, thereby guarantee the complete machine level.
The utility model can accurately be measured the suspension lifting height; Linkage assembly can adapt to multivariant motion simultaneously; Therefore in use can not damage owing to multidirectional stressed, angular transducer is owing to the protection of installation site and linkage assembly, also corresponding prolongation in its serviceable life.
Linkage assembly fit angle sensor is realized the suspension height measurement in the utility model, can also use driving lever fit angle sensor to realize, but sensor need be installed in hanger bracket and the hinged bearing pin end of balance arm in latter's scheme.High for load-bearing capacity; Use the suspension of big model tire; The bearing pin that hanger bracket is connected with balance arm is sandwiched in the tire inboard, has not had the installing space of sensor, so the scheme of driving lever fit angle sensor measurement suspension height is not suitable for the limited situation of structure space of installation.
Can find out that by the foregoing description the utility model detects the rotational angle of balance arm, and then is converted into suspension height through angular transducer and linkage assembly, can accurately detect suspension height, and have advantage simple in structure, that the life-span is long.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
