Description

The excitation type compacting machine

The utility model belongs to the oscillating machinery field, is a kind of excitation type compacting machine that obtains vibration force with shock electric machine.

The compacting machinary of using the inertia vibration generator principle in the prior art is a lot, and as frog rammer, vibratory plate compactor, vibratory roller, vibrating spear, shock electric machine etc., they all adopt traditional even matter rotor motor and the eccentric block on the shaft extension as exciting source.These mechanical structures slightly complicated are huge, use inconvenience, can not be used in channel shaped foundation ditch compacting operation as road roller; The frog is rammed and can make channel shaped foundation ditch compacting operation, but is difficult for tune, and can not be applied in and make the cast compacting operation in the lime-soil column; Though vibratory plate compactor energy cast compacting operation shifts, carries inconvenient.The most important thing is, the ratio that the eccentric rotating mass in these machineries accounts for the complete machine quality very little (as traditional shock electric machine), the circumference that eccentric mass produces radially inertia force has greatly by the inertia force counteracting of the big quality of body.So the exciting force that the motor unit power of these compacting machinaries can produce is less.

The purpose of this utility model provides a kind of compact conformation, uses flexibly, shifts convenient in carrying, the excitation type compacting machine that driving power is less.

The solution that realizes the utility model purpose is: the excitation type compacting machine that is provided comprises rack-mounted shock electric machine, frame handrail and vibration pressing piece.Improvements of the present utility model are that described rotor is an imbalance rotor, it is made up of asymmetrical magnetic pole of relative rotor pivot and winding coil thereof, the asymmetric mass of described magnetic pole and winding coil is for laying particular stress on quality, and said vibration pressing piece is connected on the shell of aforementioned motor.

Above-mentioned imbalance rotor can be one, also can have a plurality of.When imbalance rotor has one, the rotation of rotor will produce radially exciting force.When imbalance rotor has when a plurality of, they are installed on the same pivot, and along the axial symmetric arrays of described rotor pivot, wherein the rotation direction of symmetrical rotor is opposite with the rotation direction of center roller, aforementioned symmetrical rotor lay particular stress on quality and eccentric throw and center roller lay particular stress on quality and eccentric throw equates.At this moment, the rotation of rotor will only produce the inertial excitation power of vertical direction.

Compared with prior art, the utility model has saved external eccentric block owing to adopted the imbalance rotor motor, not only makes compact conformation, and volume is less, and is easy to use, flexible, and can produce bigger exciting force under the condition of identical input power.In addition, the utility model also can reach the purpose that only produces vertical exciting force by the mode that is symmetrical arranged a plurality of belts vertically.

Below in conjunction with accompanying drawing content of the present utility model is described in detail.

Fig. 2 is the distribution map of Fig. 1 rotor.

Fig. 3 is the structural representation of second embodiment of the utility model.

Fig. 4 is the structure diagram of the 3rd embodiment of the utility model.

Fig. 1, Fig. 2 have provided the example of the utility model as the vertical rammer compacter.The shell of its motor 1 (being stator) 11 is fixed on the frame 2, and three phase-wound rotors 12,13,14 of motor are installed on the same pivot 15, and their magnetic pole is offset to a side of pivot 15, thereby constitutes imbalance rotor.These three rotors are along the axial symmetric arrays of pivot 15, and the rotation direction of wherein symmetrical rotor 12,14 is opposite with the rotation direction of center roller 13, symmetrical rotor lay particular stress on quality and eccentric throw and center roller lay particular stress on quality and eccentric throw equates.During the rotor rotation, each rotor exciting force mutual superposition in vertical direction, the exciting force on other directions is then cancelled out each other, so only produce the exciting force of vertical direction.The vibration pressing piece of this rammer compacter is a tamping plate 21 with baseplane, and it is positioned at the below of motor 1, and is connected on the shell 11 of motor 1.Frame is provided with handrail 22, in order to alleviate vibration to operating personnel's harm with avoid Danger Electric shock risk, the handrail of rammer compacter is made up of sebific duct 23, steel pipe 28 and junction plate 25, wherein an end of two steel pipes 28 and frame 2 are affixed, the other end respectively with the two ends socket of a sebific duct 23, junction plate 25 is pressed on the socket section of sebific duct and steel pipe, and is fastenedly connected with screw.Power control switch 24 is located on the junction plate 25.For the ease of shifting, also be provided with wheel shaft clamp 26 on the frame of this rammer compacter, be used to clamp road wheel 27.

Fig. 3 is the example of the utility model as the tumbling-type vibratory compactor.Its frame 3 is formed by the first half 32 that is provided with loading case 31 with as the Lower Half 33 of shock electric machine pivot 41 supports, link to each other by spring 34 between the upper and lower half of frame 3, handrail 35 is connected the first half 32 of frame, and the structure of handrail is same as shown in Figure 2.The imbalance rotor 42 of shock electric machine 4 has one, and the shell 43 of motor 4 is a cylindrical shape, and it is again simultaneously the vibration pressing piece.Because just motor pivot 41 is bearing on the Lower Half 33 of frame, so columnar motor housing 43 is free to rotate, promptly the motor housing 43 of compacting machine directly presses roller to use as shaking.Load case 31 and can load weight, in order to increase consolidation effect.Rotor 42 will produce radially exciting force, motor housing 43 when rotating---and shake and press roller tumbling-type vibration thereupon.
