DETAILED DESCRIPTION

In order to make the technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

As shown in Figure 1, a variable frequency energy-saving tamping rod includes a vibrating rod body 1 for connecting to a motor to drive vibration. A replacement rod head 2 is provided at the head of the vibrating rod body 1. A connecting pipe section 3, an assembly connection part 4 and a transmission joint 5 are sequentially connected to the tail of the vibrating rod body 1, so as to achieve the drive transmission effect while improving compatibility through the assembly connection part 4 and the transmission joint 5 when inserted into the machine end. The motor at the machine end is connected to a frequency converter, and the frequency converter controls the speed of the motor according to the feedback of the vibrating rod body 1, so that the variable frequency energy-saving tamping rod has the effects of efficient frequency conversion, energy saving and reduced difficulty of use.

In order to achieve an effective frequency conversion control effect, the frequency converter is connected to a frequency conversion control module. The frequency conversion control module is connected to the vibrating rod body 1 and is provided with a sound sensor for monitoring the contact vibration degree between the vibrating rod body 1 and the ramming material. When the volume between the vibrating rod body 1 and the ramming material received by the sound sensor is less than a set threshold, the speed of the motor is controlled to reduce the set value. Among them, the sound sensor is connected to a frequency conversion driver for driving and moving along the length direction of the vibrating rod body 1.

It should be noted that, as shown in Figures 1 and 2, the frequency conversion drive is composed of a drive motor 6, a screw 7, and a fixed sleeve 8. The fixed sleeve 8 is threadedly connected to the screw 7, and one side is in contact with the inner side of the vibration rod body 1, and the sound sensor is fixed on the side of the fixed sleeve 8 facing the vibration rod body 1. Therefore, after the volume between the head of the vibration rod body 1 and the tamping material is reduced, it continues to move toward the tail, so that during the movement, the set value for controlling the motor speed reduction is gradually reduced, that is, the reduction in motor speed gradually decreases as the sound sensor gradually moves toward the tail of the vibration rod body 1, so as to control the vibration rod body 1 to output effective vibration tamping action while saving energy. Among them, the control unit of the drive motor 6 is connected to the sound sensor, so as to achieve the purpose of effectively controlling the movement of the sound sensor.

In this embodiment, two variable frequency drivers are provided and symmetrically distributed on both sides of the vibration rod body 1 , so as to more accurately obtain data between the vibration rod body 1 and the ramming material based on the mean value, thereby improving the control accuracy of the vibration rod body 1 .

In order to improve the performance of the variable frequency energy-saving tamping rod and the monitoring effect of the sound sensor, the outer side of the vibration rod body 1 is a metal alloy outer layer, so that the vibration rod body 1 has a significantly improved hardness and achieves the purpose of wear resistance, impact resistance and extrusion resistance.

In summary, the present application provides a variable frequency energy-saving tamping rod, which, during use, obtains the volume formed by tamping between the vibrating rod body 1 and the tamping material through the sound sensor in the vibrating rod body 1, and then compares the volume with the set threshold value to effectively control the motor speed output and thus achieve the effect of effective variable frequency energy-saving drive; wherein, when the volume at the head of the vibrating rod body 1 is less than the threshold, the sound sensor is controlled by the variable frequency driver to move from the head to the tail of the vibrating rod body 1, so as to combine the tamping effect of different depths of the vibrating rod body 1 inserted into the tamping material and the function of the motor variable frequency output, so that the variable frequency energy-saving tamping rod can achieve the purposes of efficient frequency conversion, energy saving and reduced difficulty of use.
