Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically to a cutting device for highway construction. Background Technology

[0002] In road construction, after the cement pavement has dried, joint cutting is required. Due to the principle of thermal expansion and contraction, cement also expands and contracts with temperature changes, which can damage the cement structure and affect the lifespan of the road surface. Therefore, expansion joints are needed to ensure the cement has room for expansion and contraction. Joint cutting machines are a common construction tool in road engineering, mainly used to cut expansion joints laterally on newly paved cement pavements. Existing technology publication CN210916935U proposes a joint cutting device for highway engineering, which uses a first and second cutting blade for simultaneous cutting. However, its structure is too simple and its function is limited. When cutting joints on highway pavements, it can only cut to a fixed depth and cannot adjust the cutting depth according to actual conditions. Furthermore, manual cleaning of the cut area is required after the cutting operation, resulting in low automation and high labor intensity. Therefore, this paper addresses these problems through in-depth research. Utility Model Content

The double-blade cutting structure includes a U-shaped frame 6 set on the movable seat 5. A drive motor 7 is set at one end of the U-shaped frame 6. The output end of the drive motor 7 is connected to the input end of the reducer 8. A fixed shaft 9 is rotatably set inside the U-shaped frame 6. One end of the fixed shaft 9 is connected to the output end of the reducer 8. Two sets of circular cutting blades 10 are symmetrically arranged on the upper part. A spray cooling component is installed on the frame 1, with one end of the spray cooling component facing the circular cutting blades 10. A vertical adjustment mechanism is integrated on the frame 1, and the height of the double-blade cutting structure is adjusted in the vertical direction using the screw module 3. This, together with the two sets of circular cutting blades 10 on the fixed shaft 9, enables rapid cutting of the road surface at the cutting position. The double-blade structure design can complete the cutting and severing of the cutting edge in one operation. An impact crushing structure is set on one side of the double-blade cutting structure, which can move with the frame 1 and impact and crush the strip road surface after cutting while moving, turning the strip cement blocks in the cutting into smaller pieces. Under the pushing action of the cleaning component at the rear of the frame 1, the cement fragments in the cutting are pushed out to the side of the roadbed. The structure is simple, the operation is continuous, and the cutting and cleaning operations can be completed in one operation, greatly reducing the intensity of manual labor.

[0019] In the specific implementation process, as a preferred configuration, the above-mentioned spray cooling component includes a water tank 11, a booster pump 12, and a spray head 13.

The water is then injected into the spray head 13 through the flexible connecting pipe and sprayed onto the circular cutting blade 10 to cool it down. The spray water can cool the circular cutting blade 10 while also reducing dust.

[0020] In specific implementation, as a preferred configuration, the aforementioned impact crushing structure includes a guide seat 14, a slide rod 15, a hammer 16, and an impact control component.

When in use, the impact cylinder 17 is activated, and the impact column 18 on the telescopic end of the impact cylinder 17 impacts the pad plate 19. When impacted, the pad plate 19 moves downward, pushing the slide rod 15 and the hammer head 16 downward, thereby impacting and breaking the strip-shaped cement at the cut position. When the telescopic end of the impact cylinder 17 retracts, the compression spring 20 resets and drives the slide rod 15 upward, so that the hammer head 16 resets. During the movement of the frame 1, the continuous impact and breaking action of the strip-shaped cement block is achieved.
