The purpose of this utility model is just to provide in order to address the above problem a kind of frog hammer of easy startup.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of frog hammer of easy startup, comprise rammer frame, tamping plate, motor and hammer ram, described tamping plate is arranged on the below of described rammer frame, described motor and hammer ram are arranged on the top of described rammer frame, the torque output of described motor is connected with the torque power shaft of described hammer ram by driving-belt, described hammer ram comprises rotating shaft, cylinder, return spring, eccentric block, guide rail and two baffle plates, two described baffle plates are separately positioned on the two ends of described cylinder, described rotating shaft is arranged on its center along the axis of described cylinder and described baffle plate, the two ends of described rotating shaft are all arranged on the outside of two described baffle plates and the torque power shaft for described hammer ram, described guide rail is arranged in described cylinder, and its two ends are fixedly connected with described cylinder inner wall with described rotating shaft respectively, described eccentric block is arranged on described guide rail and can slides along described guide rail, the two ends of described return spring are fixedly connected with described eccentric block with described rotating shaft respectively.
Return spring is in contraction state in the time not working, and the distance of eccentric block and rotating shaft is less, and hammer ram is in the time starting, and the moment of torsion needing is less; In the time that rammer is normally worked, eccentric block is under the effect of centrifugal force, and return spring is in elongation state, and the distance of eccentric block and rotating shaft is larger, makes hammer ram can drive rammer frame to swing up and down.
Preferably, described motor is dual-axle motor, and two output shafts of described motor are connected with the two ends of described rotating shaft by driving-belt respectively.
Particularly, described guide rail comprises the guide rod of two " L-types ", the short end of two described guide rods is all fixedly connected with described rotating shaft, and the long limit end of two described guide rods is all fixedly connected with the inwall of described cylinder, and two described guide rods are symmetrical arranged along the axis of described rotating shaft.
Particularly, described eccentric block is sector eccentric block, and the radius of described eccentric block inner side equates with the radius of described rotating shaft, and the radius outside described eccentric block equates with the internal diameter of described cylinder.
Particularly, on described eccentric block, be provided with the through hole corresponding with described guide rail.
The beneficial effects of the utility model are:
The frog hammer that the utility model easily starts is provided with the eccentric block that can slide along the radius of hammer ram, rammer in the time of work, eccentric block in the effect lower slider of centrifugal force to hammer ram edge; Rammer in the time shutting down, eccentric block in the effect lower slider of return spring to hammer ram middle part; Thereby reduce the starting torque of rammer, can effectively reduce the active force that while startup, motor, driving-belt, rotating shaft etc. are subject to, extended its application life.
Brief description of the drawings
Fig. 1 is the structural representation of the frog hammer of easy startup described in the utility model;
Fig. 2 is that the master of hammer ram described in the utility model looks sectional view;
Fig. 3 is the side view cutaway drawing of hammer ram described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As Fig. 1, shown in Fig. 2 and Fig. 3, the frog hammer that the utility model easily starts, comprise and ram frame 1, tamping plate 4, motor 2 and hammer ram 3, tamping plate 4 is arranged on the below of ramming frame 1, motor 2 and hammer ram 3 are arranged on the top of ramming frame 1, the torque output of motor 2 is connected with the torque power shaft of hammer ram 3 by driving-belt, hammer ram 3 comprises rotating shaft 32, cylinder 31, return spring 34, eccentric block 33, guide rail 35 and two baffle plates 36, two baffle plates 36 are separately positioned on the two ends of cylinder 31, rotating shaft 32 is arranged on its center along the axis of cylinder 31 and baffle plate 36, the two ends of rotating shaft 32 are all arranged on the outside of two baffle plates 36 and the torque power shaft for hammer ram 3, guide rail 35 is arranged in cylinder 31, and its two ends are fixedly connected with cylinder 31 inwalls with rotating shaft 32 respectively, eccentric block 33 is arranged on guide rail 35 and can slides along guide rail 35, the two ends of return spring 34 are fixedly connected with eccentric block 33 with rotating shaft 32 respectively, motor 2 is dual-axle motor 2, two output shafts of motor 2 are connected with the two ends of rotating shaft 32 by driving-belt respectively, guide rail 35 comprises the guide rod of two " L-types ", the short end of two guide rods is all fixedly connected with rotating shaft 32, the long limit end of two guide rods is all fixedly connected with the inwall of cylinder 31, two guide rods are symmetrical arranged along the axis of rotating shaft 32, eccentric block 33 is sector eccentric block 33, the radius of eccentric block 33 inner sides equates with the radius of rotating shaft 32, the radius in eccentric block 33 outsides equates with the internal diameter of cylinder 31, on eccentric block 33, be provided with the through hole corresponding with guide rail 35.
The operating principle of the frog hammer that the utility model easily starts is as follows:
In the time that rammer is not worked, return spring 34 is in contraction state, and eccentric block 33 is positioned at the middle part of cylinder 31; After rammer starts, motor 2 rotates and drives hammer ram 3 to rotate, and the centrifugal force of eccentric block 33 is less than the elastic force of return spring 34, and therefore now eccentric block 33 is less with the distance of rotating shaft 32, so the moment of torsion needing is less; After hammer ram 3 accelerates gradually, the linear velocity of eccentric block 33 increases, and the centrifugal force of eccentric block 33 is greater than the elastic force of return spring 34, and therefore eccentric block 33 slides at the edge along guide rail 35 to hammer ram 3 gradually, make it drive rammer frame 1 and tamping plate 4 to vibrate, realize the compacting to ground.
