Abstract

The invention discloses a road bridge joint cutting device. The road bridge joint cutting device comprises a control body, a display screen and a handle, wherein an outer wall of the control body is fixedly connected with the display screen, an outer wall of the display screen is connected with an inner wall of the control body, the bottom of the display screen is fixedly connected with the handle, and an outer wall of the handle is connected with the outer wall of the display screen; telescopic devices are fixedly connected to the two sides of the bottom of the control body, rotating frames are fixedly connected to the two sides of the bottom of the control body, transverse sliding grooves are fixedly connected to the middles of outer walls of the rotating frames, lead screws are fixedly connected to the middles of the transverse sliding grooves, and cutting wheels are movably connected to the middles of the rotating frames. The road bridge joint cutting device is advantaged in that convenience of the device body is improved by the display screen, practicability of the device body is improved through the handle, flexibility of the device body is improved through the telescopic devices, practicability of the device body is improved through the rotating frame, flexibility of the device body is improved through the transverse sliding grooves, and the joint cutting device is suitable for use and has wide development prospects in the future.

Description

technical field [0001] The invention belongs to the technical field of road machinery, in particular to a slitting device for road bridges. Background technique [0002] In the process of road and bridge construction, it is often necessary to cut joints on the road surface. Since concrete is not compressive but not tensile, concrete will produce tensile stress cracks under the long-term action of air temperature, rain, snow and ice. The purpose of cutting is to induce regular cracks in concrete and reduce irregular cracks. [0003] Although the traditional slitting machine has a front guide wheel or a laser marking instrument, it still relies on manual movement of the slitting machine. Deviations are inevitable during the movement process, resulting in non-linear slitting. If the turret is kept at In the horizontal state, it will take up a lot of space when it is placed after use, and it is not very convenient for the staff to carry it. When using the turret, the position o...
