Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to a road cutting machine for road construction. Background Art

[0002] Road cutting is a necessary construction method, widely used in the fields of construction, municipal administration, transportation, etc. The following is the necessity of road cutting. Road cutting helps to reduce road cracks, increase road compression resistance, and improve road smoothness. The road surface is exposed to wind, sun, water vapor erosion, and heavy objects for a long time, which is prone to cracks, poor elasticity, and other problems. Through cutting construction, the road surface can be split evenly, delaying the expansion and deepening of cracks, increasing the road compression resistance, and improving driving safety. It can also reduce the tension and stress concentration of the road surface, reduce the probability of road disease, and thus extend the service life of the road.

[0003] After the existing road cutter completes the cutting operation, the cutting blade may continue to rotate for a period of time due to inertia. This phenomenon may not only cause damage to the cutter device itself, reducing its service life and performance, but more importantly, it may also pose a serious safety threat to the user, such as causing cuts, splashes and other accidents. For this reason, we propose a road cutter for road construction. Utility Model Content

The setting of the carrying box 19 makes it convenient for the operator to store and take out tools and spare parts, thereby improving the convenience of work.

[0033] Furthermore, the outer surface of the handle 2 is coated with rubber particles and a film-forming resin. The rubber particles and the film-forming resin coated on the outer surface of the handle 2 increase the comfort and friction of the operator when holding it, and help to improve the operational stability.

[0034] Furthermore, the support assembly includes a support rod 4, a support base 5 and a support plate 6. The bottom of the support rod 4 is fixedly connected to the top of the support base 5, and the top of the support rod 4 is fixedly connected to the bottom of the support plate 6. The support plate 6 is arranged in a semicircular shape, and the curvature of the support plate 6 is equal to the diameter of the frame 1. Firstly, the setting of the support assembly is to ensure the stability and balance of the frame 1. The semicircular design of the support plate 6 enables it to match the curved structure of the frame 1 to provide effective support. The support base 5 ensures the stability of the entire device on the ground.

[0035] Furthermore, the cutting assembly includes a fixed shaft 7, a cutting motor 8, a cutting disk 9 and a fixed plate 20, both ends of the fixed plate 20 are fixedly connected to the fixed shaft 7 through connecting rods, the bottom of the fixed shaft 7 is fixedly connected to the top of the frame 1 through a connecting rod, a groove is opened inside the fixed plate 20, the cutting disk 9 is arranged inside the groove, both ends of the cutting disk 9 are rotatably connected to the fixed plate 20 through connecting rods, one end of the cutting motor 8 is fixedly connected to the outer wall of the fixed plate 20, the output end of the cutting motor 8 extends to the inside of the fixed plate 20 through the connecting rod and is hinged to the cutting disk 9, when it is necessary to cut the road, the cutting motor 8 is started to drive the cutting disk 9 to rotate in the groove of the fixed plate 20, and since the fixed plate 20 is connected to the frame 1, the cutting disk 9 can cut the road as the frame 1 moves.

[0036] Furthermore, the brake stop assembly includes a linkage motor 11, a threaded screw 12, a linkage shaft 13, a mounting column 14, a first linkage rod 15, a second linkage rod 16, a clamping rod 17 and a clamping sheet 18. The bottom of the linkage motor 11 is fixedly connected to the top of the fixing plate 20. The mounting plate 10 is arranged at one end of the fixing plate 20 close to the cutting disc 9. The bottom of the mounting plate 10 is fixedly connected to the top of the fixing plate 20. The bottom of the mounting column 14 is fixedly connected to the two ends of the top of the mounting plate 10. The top of the mounting column 14 is rotatably connected to one end of the first linkage rod 15 through a connecting rod. The other end of the first linkage rod 15 is rotatably connected to the center of the second linkage rod 16 through a connecting rod. The output end of the linkage motor 11 is hinged to one end of the threaded screw 12. The other end of the threaded screw 12 is connected to the linkage shaft 1 3 are threadedly connected together, both sides of the linkage shaft 13 are rotatably connected with one end of the second linkage rod 16 through the connecting rod, the other end of the second linkage rod 16 is rotatably connected with the clamping rod 17 through the connecting rod, and the other end of the clamping rod 17 is fixedly connected with the clamping piece 18 near the side of the cutting disk 9. After the cutting is completed, the linkage motor 11 drives the threaded screw 12 to rotate, thereby driving the linkage shaft 13 and the second linkage rod 16 connected thereto to move. The movement of the second linkage rod 16 drives the clamping rod 17 and the clamping piece 18 to approach or move away from the cutting disk 9 through the linkage effect of the first linkage rod 15. The clamping piece 18 is made of ceramic material, which has extremely high hardness and wear resistance, and has excellent high temperature resistance. The clamping piece 18 contacts with the cutting disk 9, so that the cutting disk 9 is quickly stopped in a short time.

[0037] Furthermore, the material of the clamping piece 18 is ceramic. During the road cutting process, the clamping piece 18 needs to frequently contact the road surface, so it must have sufficient hardness to resist wear and be able to withstand high temperatures without deformation or damage, thereby ensuring the stability and reliability of the clamping piece 18 in a high temperature environment.

[0038] Working principle: First, the support assembly is set to ensure the stability and balance of the frame 1. The semicircular design of the support plate 6 enables it to match the curved structure of the frame 1 to provide effective support. The support base 5 ensures the stability of the entire device on the ground. When it is necessary to cut the road, the cutting motor 8 starts to drive the cutting disc 9 to rotate in the groove of the fixed plate 20. Since the fixed plate 20 is connected to the frame 1, the cutting disc 9 can cut the road as the frame 1 moves. The rubber particles and film-forming resin coated on the outer surface of the handle 2 increase the comfort and friction of the operator when holding it, which helps to improve the stability of operation. After the cutting is completed, the linkage motor 11 drives the threaded screw 12 to rotate, thereby driving the linkage shaft 13 and the second linkage rod 16 connected thereto to move. The movement of the second linkage rod 16 drives the clamping rod 17 and the clamping plate 18 to approach or move away from the cutting disk 9 through the linkage action of the first linkage rod 15. The clamping plate 18 is made of ceramic material. The ceramic material has extremely high hardness and wear resistance, and has excellent high temperature resistance. The clamping plate 18 contacts the cutting disk 9, so that the cutting disk 9 is quickly stopped in a short time, thereby avoiding possible safety hazards. This quick-response braking mechanism is crucial to ensuring the safety of the operator.
