Description

Vibration smoothing device for road construction concrete

technical field

The utility model relates to a concrete vibration smoothing device for road construction, which belongs to the technical field of concrete construction equipment.

Background technique

In the prior art, the compacting force exerted by the troweling device used in the concrete construction process is mainly realized by gravity or manpower. The troweling device that uses gravity needs a large weight, and the weight is difficult to adjust, so it is very inconvenient during the construction process; the concrete troweling device that uses human action to achieve smoothing is very difficult for the operator's technical level. The requirements are high, otherwise it is difficult to ensure the consistency of the smoothing process. Based on the above problems, it is necessary to design a smoothing device that can control the vibration of the concrete smoothing process without heavy objects or manpower.

A drive gear is installed on the shaft sleeve, and the drive gear meshes with the transmission gear, and the transmission gear is installed on the drive motor; the spline The end of the shaft is connected with the cam mechanism, and a spring return device is provided on the spline shaft.

The spring return device is configured as two tension springs arranged at an angle, and the ends of the tension springs are connected to the inside of the housing.

The cam mechanism is driven by the drive motor through a reduction gear.

The cam mechanism is driven by a second drive motor.

The transmission ratio of the driving gear to the transmission gear is 1:1.

The vibration troweling device for road construction concrete described in the utility model realizes the telescopic movement of the spline shaft through the cam device, and ensures the reset of the spline shaft through the spring reset device, so as to realize the vibration control of the troweling disc; The drive motor controls the shaft sleeve and then controls the operation of the spline shaft, thereby realizing the rotation control of the troweling disc.
