Joint cutter for highway construction

Abstract

The invention discloses a joint cutter for highway construction. The device comprises a water tank, a handle, a motor shell, a supporting plate and a buffer spring. The water tank is fixed to one sideof the top end of the supporting plate. The motor shell is fixed to the side, away from the water tank, of the supporting plate. A motor is mounted on one side, far away from a cooling fan, of the motor shell. A rotating shaft is mounted at the output end of the motor. A diamond saw blade is arranged on the side, away from the rotating shaft, of the telescopic rod. A protective shell is arrangedabove the diamond saw blade. The water tank is communicated with the protective shell through a water pipe. A storage battery shell is fixed to the top end of the motor shell, and a storage battery isinstalled in the storage battery shell. A guide rod is hinged to the center of the side wall of one end of the supporting plate, and a guide wheel is hinged to the interior of a guide wheel groove. Working fatigue of an operator is relieved, the service life of the motor device is prolonged, and the application range of the road joint cutter is widened.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a slitting machine for highway construction. Background technique [0002] Although the concrete cutting machine is a small machine tool with a simple structure, it plays a huge role in the construction of cement pavement. The cutting is also an indispensable link in the construction, which directly affects the strength and life of the road surface. Its working principle is to drive the diamond through power. The saw blade completes the slitting operation. According to the weight of the slitting machine itself, it can be divided into three types: heavy, medium, and light. The slitting machines used in road construction in China are mainly medium-sized, and their power sources are many. It is an electric motor or a diesel engine. The ultra-light seam cutting machine is used in the construction of higher-grade roads. It uses hydraulic technology. There is almost no rese...

[0002] Although the concrete cutting machine is a small machine tool with a simple structure, it plays a huge role in the construction of cement pavement. The cutting is also an indispensable link in the construction, which directly affects the strength and life of the road surface. Its working principle is to drive the diamond through power. The saw blade completes the slitting operation. According to the weight of the slitting machine itself, it can be divided into three types: heavy, medium, and light. The slitting machines used in road construction in China are mainly medium-sized, and their power sources are many. It is an electric motor or a diesel engine. The ultra-light seam cutting machine is used in the construction of higher-grade roads. It uses hydraulic technology. There is almost no research in this area in our country. The technical requirements are too high and the development is slow. It has broad development prospects, because the strength (ability to resist plastic deformation), hardness (the ability to resist harder objects entering its interior), and stiffness (the ability to resist elastic deformation) of concrete pavement have a great relationship with the age of the pavement. The hardness is proportional to the age. The weight of the cutting machine required for cutting roads of different ages is also different. According to the hardness of the road surface, the appropriate cutting machine is selected. However, the vibration of the road cutting machine is relatively large at present. The handle of the road slitting machine is fixedly connected, which is likely to cause operator fatigue. The motor of the road slitting machine does not have a cooling device, which is likely to shorten the life of the motor, and the use range of the diamond saw blade of the road slitting machine is low, resulting in the use of the inconvenience
