Slotting device for road construction

Abstract

The invention discloses a slotting device for road construction. The slotting device includes a base frame, the base frame is a metal rod frame, mobile wheels in matrix distribution are arranged at the bottom of the base frame, a vertical frame is arranged at the tail end of the top surface of the base frame, a handle is arranged at the top of the vertical frame, a rotating frame rotatably connected with the base frame is further arranged on the upper part of the base frame, the rotating frame includes a supporting box, a limiting rotating rod and an installation rod, the limiting rotating rodis rotatably located in the center of the side edge of one side of the supporting box, the installation rod is fixedly connected with the limiting rotating rod, a fuel tank and a driving motor are successively arranged on the supporting box in a superimposed mode, and an output shaft of the driving motor is located on the side face of the driving shaft and arranged in the horizontal direction. According to the slotting device for road construction, due to the fact that the base frame and the rotating frame are rotatably connected, during the slotting work, the height of a slotting knife can be adjusted through rotation of the rotating frame, and thus the slotting work with different depths is achieved; and the rotating frame wholly rotates, and thus the position between the output shaft and a driving shaft of the driving motor is relatively stable, so that the stability of the mechanical structure is ensured.

Description

technical field [0001] The invention relates to road construction equipment, in particular to a road construction slotting device. Background technique [0002] After the highway is completed and opened to traffic, due to the wear and impact of the wheels, the erosion and weathering of natural forces such as heavy rain, floods, sandstorms, ice and snow, sun exposure, and ice melting, as well as man-made damage and some defects left over from construction, the quality of the road will be affected. will gradually decrease. Therefore, after the highway is completed and opened to traffic, maintenance and repair measures must be taken, and continuous updating and improvement must be carried out. In highway maintenance and repair, a slotting machine is often used to slot and clean the damaged road surface into a regular shape before repairing. [0003] Most of the current road slotting devices adopt a hydraulic lifting structure to adjust the position of the slotting knife, such...

Problems solved by technology

[0003] Most of the current road slotting devices adopt a hydraulic lifting structure to adjust the position of the slotting knife, such as a kind of environment-friendly dust-absorbing road slotting machine proposed by Chinese patent announcement number CN207176467U, and a kind of municipal road slotting machine proposed by CN108755368A Inspection and maintenance of slotting devices, etc., but because the maintenance road is often not kept level, and the hydraulic adjustment method is not flexible, the depth of slotting cannot be guaranteed to be satisfactory, and the hydraulic lifting must ensure that the motor used to drive the slotting knife is lifted and lowered synchronously. If the consumption is too large, it is easy to cause the problem of inflexible adjustment, resulting in the need for multiple repetitions to meet the expected effect
