Abstract
The utility model discloses a surface vibrator with adjustable excitation force. The surface vibrator comprises a motor and a movable eccentric block with an adjustable eccentric distance. An output shaft of the motor is fixedly connected with a fixed eccentric block. The movable eccentric block is rotatably sleeved on the output shaft of the motor and is fixed by the aid of a puller bolt. The surface vibrator with the adjustable excitation force has the advantages that the weights of the eccentric blocks can be adjusted, and the excitation force can be adjusted according to actual engineering construction or geotechnical testing requirements, so that vibrating compaction effects of different models of vibrating rollers, road rollers and the like during crushed stone construction for foundations, rock-fill dams and road surfaces of airports can be simulated; both vibration force and vibration amplitude can be adjusted; the surface vibrator is used as a special device for geotechnical engineering tests and can be used in industrial standard SL237-058-1999 coarse grain consolidation tests and SL237-060-1999 coarse-grained soil triaxial compression tests.
Description
Technical field
The utility model relates to vibrator field, is a kind of surface vibrator of adjustable exciting force.
Background technology
Surface vibrator is implemented vertically to vibration force the thing that shaken, and makes to be comprised by the thing that shakes that the packing of the construction materials such as rubble, gravel, sandy gravel, sand or other granular substance reaches the pre-provisioning request of design and construction.What in existing surface vibrator, set is all fixing sliding shoe, and its exciting force is fixed, and exciting force size is non-adjustable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of surface vibrator of adjustable exciting force, can regulate according to heavy construction actual needs the size of vibrator exciting force.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of surface vibrator of adjustable exciting force, comprise motor, and the output shaft of motor is fixedly connected with fixed eccentric block, is also provided with the movable eccentric block of adjustable eccentric distance.
Described movable eccentric block is rotatably sleeved on the output shaft of motor, and is fixed by puller bolt.
Termination at the output shaft of motor is also provided with screw thread, and clamp nut and output shaft are threaded connection movable eccentric block and fixed eccentric block are compressed.
Described movable eccentric block is provided with pointer, in the corresponding position of motor, is provided with scale.
The surface vibrator of a kind of adjustable exciting force that the utility model provides, the movable eccentric block by arranging, can regulate according to actual needs, thus the vibrating roller, road roller etc. that can simulate different model are to ground or the vibrating compacting effect of filling dykes and dams; Vibration force and amplitude are all adjustable.
Device of the present utility model can be used as the special purpose device of Geotechnical Engineering test, can be used for industry standard SL237-058-1999 coarse granule consolidation test and SL237-060-1999 coarse-grained soil triaxial compression test,
Device of the present utility model is constructing device flexibly, can be used for ground in civil construction project and Hydraulic and Hydro-Power Engineering, earth embankment, Rockfill Dam, road metal bed course, airport blotter etc. and is difficult to the compacting construction with the position of large-scale rolling compaction machine compacting.
The main performance contrast of the utility model and vibrating roller:
In table, known vibrating roller grinds wide 2.0～2.17m, and vibrating roller grinds and heavily can be absorbed in construction material when roller compaction construction, has arcwall face to contact with aspect, the about 0.5m of arc length, and contact area is about 1.0～1.085m
2, therefore device of the present utility model grinds close to the unit are exciting force of the thing that shaken and actual vibration, can the actual roller compaction construction of simulated field 16t～25t vibrating roller.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic side view of the present utility model.
Fig. 2 is that overall structure master of the present utility model looks schematic diagram.
In figure: motor 1, fixed eccentric block 2, key 3, clamp nut 4, movable eccentric block 5, base 6, scale 7, pointer 8, puller bolt 9.
The specific embodiment
In Fig. 1,2, a kind of surface vibrator of adjustable exciting force, comprises motor 1, and the output shaft of motor 1 is fixedly connected with fixed eccentric block 2, adopts key 3 to connect in this example, is also provided with the movable eccentric block 5 of adjustable eccentric distance.
Concrete structure is: described movable eccentric block 5 is rotatably sleeved on the output shaft of motor 1, and is fixed by puller bolt 9.By the fixed position of rotary moveable eccentric block 5, i.e. the eccentric throw of adjustable eccentric block 5, thus regulate exciting force.
Preferred as in Fig. 1, in the termination of the output shaft of motor 1, be also provided with screw thread, clamp nut 4 is threaded connection movable eccentric block 5 and fixed eccentric block 2 compressions with output shaft.
Described movable eccentric block 5 is provided with pointer 8, in the corresponding position of motor 1, is provided with scale 7, in this example, scale is arranged on the case of motor 1.Structure, can learn the exciting force after adjusting according to scale thus.
The utility model main performance is as follows: maximum exciting force 69.3kN, excited frequency 50Hz, circular frequency 314.16 radian per seconds, amplitude 1.5～4mm.
The exciting force of vibrator is relevant with eccentric block quality, eccentric throw and angular speed, can be represented by the formula:
Q

Circular frequency ω=2 π f wherein;
M in formula
e-unbalance mass,, be eccentric block quality, kg;
E-eccentric throw, m;
ω-circular frequency, radian per second.
F-rotating speed, r/min
Eccentric adjustment piece quality m
ejust can obtain the vibrator of different exciting force sizes with eccentric distance e.Eccentric mass 8.5kg of the present utility model, maximum eccentricity 0.0825m, maximum exciting force 69.3kN.Angle between change activity eccentric block and fixed eccentric block just can change eccentric block quality, and movable eccentric block overlaps completely with fixed eccentric block, and now exciting force is maximum, and exciting force is the specified exciting force 69.3kN of adjustable surface vibrator.
During use; first according to required exciting force, according to the exciting force control method of appointment, regulate the size of exciting force; and then the utility model surface vibrator is uprightly put in to the Coarse Aggregate that needs compacting; such as the one-tenth mould bucket medium stone of large triaxial test or the surface of sand or gravelly soil etc.; guarantee not topple over; need if desired manpower righting, and vibrator top is hung on crane cable wire; Finally connect vibrator power supply, vibrator just starts normal operation.In short time, general 1～5 minute, coarse fodder material can be hit to the density criterion that design side requires, thereby between shortening greatly and hitting in real time, save labour, and then reach the object of saving test or construction cost of labor.
