The specific structure and working process of the invention are explained in detail in conjunction with the attached drawings as follows:
according to the general structure of the invention, as shown in figure 1, a hydraulic motor drives a main shaft and an eccentric block to form a vibration excitation device; the vibration excitation device is connected with the fixed bottom plate, the connection mode is not limited, welding can be adopted, and the connection mode can also be detachable and fastened. When the hydraulic motor drives the main shaft to rotate, the vibration excitation device generates periodic vibration under the action of the eccentric block on the main shaft, and the vibration force is transmitted to the fixed bottom plate and the telescopic bottom plate through connection, so that the side slope material is tamped. The vibration excitation device and the fixed bottom plate are installed on the hanging bracket through the shock absorber, the shock absorber can prevent vibration generated by the vibration excitation device from being transmitted to the rotary hanging bracket, the rotary hanging bracket is hinged and installed on the installation support through the first pin shaft, and the installation support is connected with the paver screed plate through the fixing bolt. The paving operation of the screed plate is advanced to drive the whole slope vibrating compaction device to move forwards together.
The vibration source in the device is that a hydraulic motor drives a main shaft to rotate, and a plurality of eccentric blocks with unequal weights arranged on the main shaft are actively driven to rotate to generate periodic vibration.
As shown in the structure diagram 5 of the eccentric block of the vibration excitation device, the number of the eccentric blocks is 3 in the present embodiment, and the eccentric blocks are completely sleeved on the main shaft and respectively fixed with the main shaft by a fastening bolt penetrating through the shaft center. When the centers of gravity of the 3 eccentric blocks are on the same side, the eccentric blocks rotate to generate the maximum eccentric moment, and the excitation force generated by the rotation is maximum. When the exciting force needs to be changed, only the fastening bolt of the middle eccentric block needs to be loosened and the middle eccentric block needs to be rotated 180 degrees around the main shaft, namely, the gravity center of the middle eccentric block and the gravity centers of the other two eccentric blocks are on opposite sides and are fixed by the fastening bolt again, and the exciting force generated at the moment is small due to incomplete offset of the eccentric moment during rotation. This can accomplish the change of the exciting force. In the structure of the embodiment, the fastening bolt penetrates through the spindle center, so that the bolt has the minimum eccentric moment, the stress of the fastening bolt is reduced to the maximum extent, and the bolt is prevented from loosening. Meanwhile, the eccentric block is arranged on the main shaft through a through hole, so that the danger caused by the eccentric block being thrown away from the main shaft after the fastening bolt is loosened is completely avoided.
The adjustment process for changing the excitation force can be performed through an inspection window located at the upper portion. The method for adjusting the exciting force is simple, convenient and reliable.
When the paving thickness is changed, the working face width of the side slope is changed. The position of the telescopic bottom plate can be adjusted to adapt to different working face widths so as to adapt to different working widths. The embodiment of the invention can be suitable for the working surface with the thickness of 350mm to 500mm of the paver according to the width of the side slope generated by the paving angle of the paver for paving different materials with different thicknesses.
Fig. 4 shows a structure diagram of the retractable bottom plate of the device of the invention. When the extension and retraction of the telescopic bottom plate need to be adjusted, the telescopic bottom plate can extend or retract along the linear guide rail only by shaking the adjusting hand wheel and driving the screw rod to rotate. In the embodiment, the hand wheel is shaken, the position of the telescopic bottom plate is changed through the screw pair, so that the real-time adjustment in the operation process can be realized, and the self-locking function of the screw pair can enable the telescopic bottom plate to stay at any position. The structure solves the problem of width adaptation of the working surface of the slope vibrating compaction device. The structure is simple and reliable, and real-time adjustment under the non-stop state can be realized.
Referring to fig. 3, the vibration exciter is connected with the base plate through the damper and the rotary hanger, and the material settling angle of the conventional paver for paving is 40-50 °. In order to adapt to the slope angle formed by different materials, the angle of the bottom plate can be adjusted by adjusting the length of the height adjusting screw on the rotary hanging bracket. The range of the adjusting angle of 30-60 degrees covers the use range of the paving material of 40-50 degrees. Meanwhile, the mounting height of the mounting bracket on the ironing plate of the paver is changed by adjusting the height adjusting screw rod, and the upper and lower positions of the bottom plate are adjusted. The bottom plate can be completely attached to the slope surface all the time when the bottom plate works at different slope angles by adjusting the angle and the height in the using process.
This example is now further described in conjunction with fig. 3. The vibration excitation device and the fixed bottom plate are installed on the rotary hanging bracket through the shock absorber, the shock absorber can avoid vibration generated from being transmitted to the rotary hanging bracket, the rotary hanging bracket is installed on the installation support through a pin shaft, and the installation support is connected with the paver screed plate through a bolt. The rotary hanger, the thread telescopic adjusting assembly and the mounting bracket form a triangular relation. The length of the thread telescopic adjusting assembly can enable the rotary hanger to rotate by taking the first pin shaft as a circle center, so that the angle of the fixed base plate of the device is adjusted. The thread telescopic adjusting component is connected with an angle adjusting hand wheel, and the length of the thread telescopic adjusting component can be adjusted by the angle adjusting hand wheel. The structure is simple to mount and adjust, and the angle can be adjusted by adjusting the hand wheel through the rotating angle, so that real-time adjustment in a non-stop state can be realized. Due to the self-locking characteristic of the thread telescopic adjusting assembly, the structure is in a triangular locking state after adjustment is completed, and the structure is stable and reliable. In order to make the bottom plate better fit the working surface, the height of the whole device can be adjusted by adjusting the height adjusting bolts on the mounting bracket. For further explanation, the mounting bracket of the present example is fixedly connected to the screed plate by 4 fastening bolts passing through 4 oblong holes on the mounting bracket in combination with fig. 1. When the height of the device needs to be adjusted, the fixing bolts are loosened without being completely screwed off, then the height adjusting screw at the top is rotated to enable the mounting support to be adjusted up and down along the long round hole, 4 fixing bolts are screwed after the mounting support is adjusted in place, and the mounting support is stably connected with the ironing plate again to complete adjustment.
When the operation is not carried out, the vibration excitation device, the fixed bottom plate, the telescopic bottom plate and the rotary hanging bracket can be separated from the mounting bracket without drawing out the cotter pin by a tool, and the storage is convenient.
The embodiment has the characteristics of vibration tamping, adjustable vibration force, adjustable width of a tamping surface, adjustable angle of the tamping surface, adjustable height position of the device and the like, and the bottom plate can be always completely attached to the slope of the slope when the operation is carried out under different slope angles by adjusting the angle and the height in a non-stop state.
