Abstract

The utility model relates to a compacting machine, which obtains the vibration force from the motor planetary motion, comprising a frame, a handrail and a vibrator. The vibrator is composed of a motor and a planetary mechanism, wherein the planetary mechanism is fixed on the frame, a planetary wheel of the planetary mechanism is fixed on the motor shaft, a central wheel of the planetary mechanism is a fixed-shaft wheel and the lopsidedness weight is equal with the summer of the motor weight and the planetary wheel weight. The motor drives the planetary wheel and rotates with the planetary wheel around the central wheel in order to generate the vibration.

Description

Compacting machine

The utility model belongs to the oscillating machinery field, is a kind of compacting machine that obtains vibration force with motor do planetary motion.

Compacting machine normally produces exciting force with the rotation of driven by motor eccentric block in the prior art, as frog rammer, vibratory plate compactor, vibratory roller, vibrating spear, shock electric machine etc.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.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 the compacting machine that driving power is less.

The solution that realizes the utility model purpose is: the compacting machine that is provided is made up of frame, handrail and vibrator.Described vibrator is made up of motor and planetary mechanism, wherein planetary mechanism is contained on the frame, the centre wheel of planetary mechanism is a fixed shaft wheel, and the planetary gear of planetary mechanism is installed on the motor shaft extension, and the quality that lays particular stress on of vibrator equals motor quality and planetary gear quality sum.That is, planetary gear is a driving wheel in this planet mechanism, and the driven by motor planetary gear rotates around centre wheel with planetary gear again when rotating, thereby produces exciting.

The utility model has adopted general-purpose machine and planetary mechanism commonly used, so easily processing; Since with motor itself as laying particular stress on quality, compact conformation not only, and lay particular stress on the large percentage that quality accounts for the complete machine quality, the exciting force that unit power is exported is big.

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

Fig. 1 is the utility model with the circumference compacting machine structure diagram of exciting force mode work radially.

Fig. 2 is the compacting machine structure diagram of the utility model with the work of alternation exciting force mode.

Fig. 3 is the alternation exciting force compacting machine structure diagram of the another kind of form of the utility model.

Fig. 4 is the axial diagrammatic cross-sectional view of Fig. 3.

As shown in Figure 1, compacting machine is made up of frame 1, handrail 14 and vibrator 3.Vibrator 3 is made up of motor 32 and planetary mechanism 33, and wherein planetary mechanism 33 is made of the gear ring 34--centre wheel, pivot 35, tie-rod 36, the planetary gear 37 that are fixed on the casing 31.Planetary gear 37 is installed on the shaft extension of motor 32, and meshes with gear ring 34, and motor 32 bodies rotate with pivot 35 through tie-rod 36 and connect.The distance of electrical axis pivot axis 35 is eccentric throw, and the quality sum that quality is motor and planetary gear is laid particular stress in rotation.Frame 1 is made up of the loading case 11 on top and the support 12 of bottom, loads between case and the support to connect with spring 13, loads to connect handrail 14 on the case.Vibrator connects for rotatable with frame, and promptly the pivot 35 of planet mechanism is contained on the support 12, and casing 31 double as vibration pressing piece---tumbling-type is pressed roller.During compacting operation, the driven by motor planetary gear rotates, and rotates around centre wheel with planetary gear, thereby produces radially exciting force, and casing 31 rolls on the spinning surface, and vibration.Because what this kind laid particular stress on singly that when rotation produce is the circumference radial load, casing 31 produces circular vibrations, the effect that loads case 11 and spring 13 can make upwards the bounce-back of exciting force component downwards, and with downward exciting force component stack to strengthen consolidation effect.

This compacting machine not only can be done the rolling compacting operation, also can make the plane vibration compacting operation.When making the plane vibration compacting operation, a fast-assembling base plate 2 is installed below vibrator 3, this base plate is provided with and the vibrator casing 31 fastening locating pieces that contact 21, is fastenedly connected by bolt 22 between locating piece 21 and the frame.

Produce the alternation exciting force as need, can on frame, symmetry install the opposite vibrator of a plurality of planetary gear rotation directions, as shown in Figures 2 and 3.

The vibrator of compacting machine shown in Figure 2 has two, and the wheel shaft of the

centre wheel

43,44 of their

planetary mechanism

41,42 is parallel, and the rotation direction of planetary gear is opposite, thereby will produce the vertical exciting force of alternation.

Fig. 3, compacting machine shown in Figure 4 are that vertical rams machine, its vibrator has three, they are symmetric arrays vertically, the planetary gear rotation direction of wherein symmetrical vibrator 51,53 is identical, and opposite with the planetary gear rotation direction of middle vibrator 52, symmetrical vibrator lay particular stress on quality and eccentric throw and middle vibrator lay particular stress on quality and eccentric throw equates.Therefore, also will produce the vertical exciting force of alternation.The convenience that shifts during for inoperative has designed a kind of transfer road wheel 61 of fast demountable, is provided with clamp 60 on the vibrator casing that is:, and clamp 60 is provided with the Card trough 62 that clamps road wheel 61.Finish when need shifting when tamping operation, only need wheel shaft with road wheel 61 snap in the Card trough 62 and get final product.
