Description

Technical Field

[0001] The utility model belongs to the technical field of concrete seam cutting, and in particular relates to a concrete seam cutting machine with adjustable seam spacing. Background Art

[0002] In modern construction, concrete is widely used in various structures due to its high strength, durability, and other excellent properties. To control concrete shrinkage and cracking and prevent irregular cracks caused by excessive shrinkage stress, concrete joint cutting is performed approximately 24 hours after pouring, when the concrete strength reaches 25% to 30% of its design strength. Currently, concrete joint cutting machines are the primary tool for this task.

[0003] Traditional concrete joint cutting machines rely primarily on manual measurement and marking, resulting in low overall construction efficiency. Furthermore, due to subjectivity and errors in manual operation, the distance between the cuts is often difficult to precisely control, affecting the uniformity and overall performance of the concrete structure. Therefore, we propose a concrete joint cutting machine with adjustable joint spacing to address these issues. Utility Model Content

[0007] It is further defined that the movable seat is an L-shaped plate structure, a fixed column is fixedly installed above the movable seat, and the fixed column is covered with an anti-slip rubber sleeve. Such a structural design is simple in structure and easy to use.

[0008] The invention further defines that the locking mechanism includes a fixing frame and a locking bolt. The fixing frame is fixedly mounted on the movable seat, and the fixing frame is movably mounted on the crossbar of the equipment truss. The fixing frame is provided with a threaded groove, and the locking bolt is threadedly connected to the fixing frame through the bolt groove. When the locking mechanism is in the locked state, the end of the locking bolt contacts the crossbar of the equipment truss.

The spare truss 2 is provided with a locking mechanism that can lock the position of the two limit guide rails 31. The movable seat 32 is an L-shaped plate structure. A fixed column 321 is fixedly installed above the movable seat 32. The fixed column 321 is provided with an anti-slip rubber sleeve. The movable seat 32 is easily pulled by the fixed column 321 to adjust the distance between adjacent slit components. The limit guide rail 31 is a concave structure, and a plurality of mounting grooves are provided on the side where the limit guide rail 31 contacts the lower end of the movable seat 32. Rotating wheels 311 are rotatably installed in the plurality of mounting grooves. The rotating wheels 311 can reduce the friction between the movable seat 32 and the limit guide rail 31, so that the resistance when the movable seat 32 moves is reduced, thereby facilitating the adjustment of the position of the movable seat 32 on the limit guide rail 31.

[0030] Automatically retractable tape measures are provided between the fixed frames 4 on adjacent movable seats 32, and LED lights are evenly fixedly installed on the upper ends of the equipment trusses 2. The LED lights facilitate observation of the equipment status and facilitate observation of the spacing data when adjusting the spacing.

[0031] The locking mechanism includes a fixed frame 4 and a locking bolt 41. The fixed frame 4 is fixedly installed on the movable seat 32. The fixed frame 4 is movably mounted on the cross bar of the equipment truss 2. A threaded groove is provided on the fixed frame 4. The locking bolt 41 is threadedly connected to the fixed frame 4 through the bolt groove. When the locking mechanism is in a locked state, the end of the locking bolt 41 contacts the cross bar of the equipment truss 2. The fixed frame 4 is symmetrically arranged on the movable seat 32, and the movable seat 32 can be firmly locked in the set position to make the slitting assembly more stable when working.

[0032] A fixing frame 5 is fixedly installed at one end of the equipment truss 2 close to the distribution box 1, and a second motor 51 and a positioning column 52 are fixedly installed on the fixing frame 5.

[0035] According to the above method, after the spacing of each cutting component 3 is adjusted, the first motor 33 works and the cutting head 34 cuts the concrete panel. When the cutting head 34 moves down to the set position, the second motor 51 works and drives the transmission shaft 53 to rotate through the first belt 55 and the second belt 56, thereby causing the power wheel 54 to drive the equipment truss 2 to move on the channel steel to cut the concrete panel. The concrete cutting machine can cut multiple seams on the concrete panel at the same time, thereby improving the cutting efficiency, saving time and effort, and the cutting spacing is adjustable, and the cutting spacing can be controlled more accurately.

[0036] The above describes in detail the concrete seam cutter with adjustable seam spacing provided by the present invention.
