Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a precast slab cutting device. Background Technology

[0002] Precast slabs, also known as floor slabs, need to be cut to the required length for proper on-site use. This requires a cutting device. Existing cutting devices use a motor to drive a high-speed rotating cutting blade to cut the slab. However, since both the motor and the blade are manually controlled, and the device lacks a directional mechanism, workers must manually align the blade with the cutting position. This not only places high demands on the operator but also creates a dangerous situation due to the close proximity of the operator to the cutting position, making it difficult to meet the usage requirements. Utility Model Content

[0003] The purpose of this invention is to provide a precast slab cutting device, which aims to solve the problems mentioned in the background art.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-7 As shown, a precast slab cutting device includes: Placement section, used to place precast slab 1; Clamping part, the clamping part is used to clamp the prefabricated plate 1 located on the placement part; The cutting part is mounted on the clamping part and can be moved on the clamping part. The spray section is used to spray cooling water onto the cutting section.

[0020] Furthermore, the placement part includes a base frame 2, with fixed blocks 3 respectively provided at both ends of the upper surface of the base frame 2, and two sets of sliding parts provided on the base frame 2 between the two fixed blocks 3. The sliding parts include movable blocks 4, with slots 5 respectively provided at both ends of the movable blocks 4, and the slots 5 are slidably connected to the base frame 2.

[0021] The base frame 2, fixed block 3, movable block 4, and slot 5 can be made of steel plate. The upper surface of fixed block 3 and the upper surface of movable block 4 are basically at the same horizontal level to support the precast slab 1. The positions of the two fixed blocks 3 on the base frame 2 remain unchanged. The two movable blocks 4 and the two fixed blocks 3 jointly support the precast slab 1. Before cutting the precast slab 1, the appropriate cutting position needs to be marked on the precast slab 1. Then, the positions of the two movable blocks 4 are adjusted so that the cutting position is between the two movable blocks 4. When a complete precast slab 1 is cut into two small precast slabs 1, the fixed block 3 and the movable block 4 on one side can support the cut precast slab 1 and prevent the cut precast slab 1 from falling off the base frame 2.

[0022] Furthermore, the clamping part includes a support frame 6, with two rollers 7 on the lower surface of one end of the support frame 6, a positioning plate 8 on the lower surface of the support frame 6, and two fixing plates 9 on the lower surface of the support frame 6. Screws 10 are rotatably connected to the two fixing plates 9, and a handle 11 is provided at one end of the screws 10. It also includes a pressure plate 12, with two guide rods 13 on one side of the pressure plate 12. The guide rods 13 are slidably connected to the two fixing plates 9. It also includes a movable plate 14 located between the two fixing plates 9. The screws 10 are threadedly connected to the movable plate 14, and the movable plate 14 is slidably connected to the guide rods 13.

[0023] After the precast slab 1 is placed on the placement section, it is supported by the support frame 6 and rollers 7, such as Figure 7As shown, the clamping part is moved to one side of the bottom frame 2, and then the support frame 6 is placed on the precast slab 1, and the positioning plate 8 is aligned with the side of the precast slab 1. At this time, the position of the cutting part also needs to be adjusted so that the cutting part is aligned with the cutting position of the precast slab 1. When the cutting part is aligned with the cutting position of the precast slab 1, the screw 10 can be rotated by the handle 11. Since the screw 10 is rotatably connected to the two fixed plates 9, and the screw 10 is threadedly connected to the movable plate 14, and the guide rod 13 is slidably connected to the fixed plate 9, the screw 10 can push the movable plate 14 to move towards the positioning plate 8 when it rotates, and then push the pressure plate 12 to move towards the positioning plate 8 through the guide rod 13. When the pressure plate 12 is aligned with the side of the precast slab 1, the support frame 6 can be clamped and fixed on the precast slab 1 by the positioning plate 8 and the pressure plate 12.

[0024] Rubber pads can be provided on the opposite side of the positioning plate 8 and the pressure plate 12. By compressing the rubber pads, the support frame 6 can be better clamped and fixed on the precast slab 1.

[0025] Furthermore, the cutting section includes two fixed rods 15 mounted on the support frame 6, and also includes a slide 16. The slide 16 is slidably connected to the fixed rods 15. A pull rod 17 is provided on one side of the slide 16. A motor 18 is mounted on the slide 16. A cutting blade 19 is mounted on the output end of the motor 18. A protective shell 20 for accommodating the cutting blade 19 is mounted on the motor 18.

[0026] The pull rod 17 can drive the slide 16 to move along the fixed rod 15 on the support frame 6. When cutting the precast slab 1, the motor 18 is powered by an external power line. The motor 18 starts and drives the cutting blade 19 to cut the precast slab 1. During the cutting process of the precast slab 1, the pull rod 17 can drive the motor 18 on the slide 16 to move slowly, so that the cutting blade 19 can further cut the precast slab 1. Since the precast slab 1 is placed on the fixed block 3 and the movable block 4, there is a gap between the cutting position of the precast slab 1 and the bottom frame 2. The gap distance is greater than 5cm. Therefore, when the cutting blade 19 cuts the precast slab 1, the cutting blade 19 will not cut to the bottom frame 2.

[0027] After the precast slab 1 is cut by the cutting blade 19, the motor 18 stops, and then the screw 10 is rotated to move the pressure plate 12 away from the precast slab 1. Then, one end of the support frame 6 is lifted and the roller 7 is brought into contact with the ground. At this time, under the action of gravity, the slide 16 will move towards the roller 7 until it can no longer slide down. Then the support frame 6 is removed from the precast slab 1, and the cut precast slab 1 can be transferred out.

[0028] Furthermore, the spray unit includes a mounting platform 21 mounted on the slide 16, a water storage tank 22 mounted on the mounting platform 21, a through groove opened on the side of the protective shell 20, a spray nozzle 23 disposed inside the through groove, and the water storage tank 22 and the spray nozzle 23 are connected by a pipe 24.

[0029] When cutting the precast slab 1, a certain amount of clean water can be added to the water tank 22. Under the action of gravity, the clean water passes through the pipe 24 and the nozzle, and is continuously sprayed onto the cutting blade 19, thereby cooling the cutting blade 19 and wetting the dust generated at the cutting position of the precast slab 1, so as to reduce the occurrence of cutting dust.

[0030] The water in the water storage tank 22 needs to meet the water demand for cutting a single precast slab 1. Water can also be added to the water storage tank during the cutting process. If there is still a lot of water in the water storage tank 22 after the precast slab 1 has been cut, the water in the water storage tank 22 can be manually transferred out, or sprayed out through the pipe 24 and nozzle, thereby reducing the weight of the spray unit and facilitating the transfer of the device.

[0031] When the support frame 6 is placed on the ground, the cutting disc 19 will not come into contact with the ground. The cutting disc 19 will maintain a safe distance from the ground to avoid damaging the cutting disc 19.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
