Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a cutting device for fine aggregate concrete floors. Background Technology

[0002] In the construction of fine aggregate concrete floors, slitting is one of the key operational steps, typically used to control concrete shrinkage and prevent cracking. Traditional slitting methods usually rely on manual hand-held cutting machines, where workers hold the cutting machine, using angle iron of appropriate length as a guide, and controlling the cutting direction through experience and vision.

[0003] The manual cutting method has the following problems: 1. Traditional manual cutting requires workers to hold the cutting machine continuously, advance it slowly, and constantly adjust the cutting direction. This is cumbersome, time-consuming, and labor-intensive, greatly affecting construction efficiency. A significant amount of time is spent completing each cutting line, resulting in a slow overall progress. 2. Traditional manual cutting requires highly skilled operators. Due to the low efficiency of handheld cutting, more workers are usually needed to complete the task, increasing both direct and indirect labor costs. With the decreasing number of skilled workers, this high-labor-cost method is no longer suitable for modern construction needs. 3. During manual cutting, workers must maintain a squatting posture for extended periods, easily leading to fatigue. Fatigue increases the risk of operational errors, potentially damaging the cutting blade or even causing flying debris that could injure workers. Prolonged use of the cutting machine also increases worker safety risks. 4. Because handheld cutting machines are difficult to control stably, traditional methods are prone to deviation during cutting, resulting in crooked cutting lines that affect the aesthetics and construction quality of the fine aggregate concrete floor. 5. To prevent the cutting blade from overheating, another worker is needed to assist with spraying cooling water. Utility Model Content

[0004] Based on the shortcomings of the prior art, this utility model provides a fine aggregate concrete floor cutting device. Through the cooperation of guide rail, cutting machine base, traveling pulley and directional pulley, it realizes precise cutting operation and greatly improves construction efficiency and cutting accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fine aggregate concrete floor cutting device, comprising a guide rail, a cutting machine base, and a cutting mechanism; the cutting machine base is mounted on the guide rail via a moving mechanism, and the cutting mechanism is mounted on the cutting machine base; the moving mechanism includes a directional pulley and a traveling pulley; the directional pulley is mounted on the lower part of the cutting machine base and located on both sides of the guide rail, and the traveling pulley is mounted on both sides of the cutting machine base and cooperates with the track of the guide rail.

[0006] Preferably, multiple directional pulleys are provided, and the multiple directional pulleys are connected by a directional pulley connecting shaft.

[0007] Preferably, it further includes a fixing mechanism, which includes an adjustable support leg and a suction cup; the adjustable support leg is installed on the lower part of the guide rail, and the suction cup is installed on the lower part of the adjustable support leg.

[0008] Preferably, the cutting mechanism includes a cutting machine motor, a cutting machine protective cover, and a cutting blade; the cutting machine protective cover is mounted on the cutting machine base, and the cutting blade is located on one side of the cutting machine protective cover and connected to the cutting machine motor.

[0009] Preferably, it also includes a cooling pipe, which is installed on one side of the cutting machine base. The cooling pipe includes a cutting blade cooling outlet and a cutting blade cooling inlet. The cutting blade cooling inlet is installed on the opposite side of the cutting blade cooling outlet and at one end close to the guide rail.

[0010] Preferably, it also includes a handle, which is mounted on the cutting machine base.

[0011] Preferably, multiple guide rails are provided, and the multiple guide rails are connected by guide rail connectors.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by using directional pulleys to hold the two sides of the guide rail, the cutting machine base can move firmly along the guide rail, avoiding lateral displacement and improving the stability and safety of the cutting process.

[0013] The traveling pulleys are installed on both sides of the cutting machine table and cooperate with the guide rails to drive the cutting machine table to move back and forth smoothly.

[0014] The combination of directional pulleys and traveling pulleys enables the cutting machine to maintain stable linear motion as it moves along the guide rail, thereby ensuring the straightness and uniformity of the cutting line and improving construction quality.

[0015] Because the cutting machine stand moves smoothly through directional pulleys and traveling pulleys, it reduces the risk of workers directly holding the cutting machine and lowers safety hazards caused by fatigue or improper operation.

[0016] The control handle design allows workers to operate the machine while standing, easily pushing it forward and reducing physical exertion when using a handheld cutting machine, thus significantly lowering the worker's labor intensity.

[0017] With a stable structure, workers do not need to directly contact the cutting blade during the cutting process, reducing safety hazards caused by fatigue operation and significantly improving construction safety.

[0018] The cooling pipes automatically cool the cutting disc during the cutting process, preventing it from being damaged by overheating, extending its service life, and further reducing equipment maintenance costs.

[0019] Therefore, this device reduces the tedious adjustments workers need to make during construction, enabling slit cutting operations to be carried out quickly and continuously, effectively shortening construction time and improving overall work efficiency. Attached Figure Description

[0027] refer to Figure 1-5As shown, this utility model discloses a fine aggregate concrete floor cutting device, including a guide rail 3, a cutting machine base 2, and a cutting mechanism. The cutting machine base 2 is mounted on the guide rail 3 via a moving mechanism, and the cutting mechanism is mounted on the cutting machine base 2. The moving mechanism includes a directional pulley 8 and a traveling pulley 6. The directional pulley 8 is installed at the lower part of the cutting machine base 2 and located on both sides of the guide rail 3, and the traveling pulley 6 is installed on both sides of the cutting machine base 2 and cooperates with the track of the guide rail 3. The directional pulley 8 can lock the two sides of the guide rail 3, and then the traveling pulley 6 drives the cutting machine base 2 to move back and forth to realize the cutting mechanism cutting at the target position. Specifically, the cutting machine base 2 is installed on the guide rail 3, and the two sides of the cutting machine base 2 are locked on the two sides of the guide rail 3 by the directional pulley 8. At the same time, the upper traveling pulley 6 is close to the guide rail, and then the cutting mechanism is fixed to the cutting machine base 2 by an adjustable clamp. The machine moves smoothly along the guide rail 3 to ensure the straightness of the cut. In this embodiment, the cutting machine base 2 is made of 8mm thick steel plate.

[0028] Multiple directional pulleys 8 are provided, and the multiple directional pulleys 8 are connected by directional pulley connecting shafts 7 so that the cutting machine base 2 can move stably along the guide rail 3, prevent lateral displacement, and ensure stability and accuracy during the cutting process.

[0029] It also includes a fixing mechanism, which comprises an adjustable support leg 4 and a suction cup 5.
