[0002] Precast slabs are used extensively in construction projects. Precast slabs are pre-fabricated concrete components manufactured and processed in a prefabrication yard, then transported directly to the construction site for installation; hence the name "precast slab."

[0014] Step 1: Place the precast slab onto the support plate;

[0015] Step 2: Rotate the screw to fix the precast plate in place with the pressure block. Place a sponge block below the center hole to prevent the cylindrical core from falling directly into the hard surface and being damaged when the core extraction is completed.

[0016] Step 3: Add clean water to the clean water tank;

[0017] Step 4: Control the motor to rotate intermittently, gradually increasing the number of rotations, so that the core drill bit gradually drills downwards to extract the core from the precast slab;

[0018] Step 5: The piston moves reciprocally. When the piston moves downward, it squeezes the air and water in the clean water tank, allowing water to enter the water outlet pipe and spray it onto the core drill bit. The number of teeth on the gear 2 is much greater than that on the gear 1. The water spray interval on the water outlet pipe is very small. The core drill bit spirals down or up, causing water to spray onto the core drill bit, thus cooling the core drill bit. The water comes into contact with the core drill bit during the core extraction process, generating dust. The water and dust mix to form wastewater, which falls into the area formed by the cooling tank and the conical cover.

Under the action of the piston two, sewage enters the round pipe through the water pipe, and most of the water enters the return water tank through the inlet pipe. Substances insoluble in water, such as sand, are deposited in the area formed by the water pipe and the conical plug.

The intermediate transmission shaft drives the block and the first cylinder to revolve. The first cylinder drives the first sphere to move along the spiral groove. The first sphere drives the first cylinder and the block to move along the height direction. The block drives the intermediate transmission shaft to move along the guide shaft and the guide groove.

The L-shaped rod one drives the ball two to reciprocate along the annular inclined groove two. The ball two drives the cylinder three to reciprocate. The cylinder three drives the piston two, the U-rod, and the conical plug to reciprocate.

[0022] As a further limitation of this technical solution, the gap between the conical cover and the core drill bit is very small.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are:

[0024] 1. This device is driven by a motor and, under the limiting action of the spiral groove, enables the core drill bit to rotate while spiraling down or up. Water is sprayed out from the water outlet pipe and comes into contact with the spiraling core drill bit, increasing the contact area and improving the cooling effect.

[0025] 2. In this device, piston one moves downwards, compressing the air and water in the clean water tank, allowing water to enter the outlet pipe and spray towards the core drill bit. The converging outlet increases the water pressure, causing the water to impact the core drill bit and fall into the area formed by the conical cover and the cooling tank, preventing water from falling through the gap between the conical cover and the core drill bit. Piston two moves back and forth. When piston two moves upwards, the conical plug enters the water pipe. Under the action of piston two, wastewater enters the water pipe, and most of the water enters the return water tank through the inlet pipe (the upper end of the inlet pipe is much higher than the bottom plate of the return water tank). Insoluble substances such as sand particles are deposited in the area formed by the water pipe and the conical plug. When piston two moves downwards, the conical plug detaches from the water pipe, and the sand particles move downwards along the conical surface of the conical plug, thus realizing water recovery and separating insoluble sand particles.

[0026] 3. Through ingenious design, this device achieves the following: during the core drilling process, the water comes into contact with the dust generated during core drilling, and the water and dust are mixed to suppress the dust. Then, the water and water-insoluble sand are separated, making it convenient to use. Attached Figure Description

[0048] Step 2: Rotate the screw 8 to fix the precast plate in place with the pressure block 9. Place a sponge block below the center hole 10 to prevent the cylindrical core from falling directly into the hard surface and being damaged when the core extraction is completed.

[0049] Step 3: Add clean water to the clean water tank 34;

[0050] Step 4: Control the motor 2 to rotate intermittently, so that the number of rotations of the motor 2 gradually increases, and the core drill bit 19 gradually moves downward to drill holes in the precast plate to extract the core.

[0051] Step 5: The piston 39 reciprocates, and the piston 39 moves downward to squeeze the air and water in the clean water tank 34, so that the water enters the water outlet pipe 28 and is sprayed from the water outlet pipe 28 onto the core drill bit 19. The number of teeth of the gear 22 is much greater than the number of teeth of the gear 21. The water spray interval of the water outlet pipe 28 is very small. The core drill bit 19 spirals down or up, so that the water is sprayed onto the core drill bit 19 to cool it down. The water comes into contact with the core drill bit 19 during the core extraction process and generates dust. The water and dust mix to form wastewater, which falls into the area formed by the cooling tank 26 and the conical cover 27.

[0052] Step Six: The piston 44 reciprocates. When the piston 44 moves upward, the conical plug 46 enters the water pipe 36. Under the action of the piston 44, sewage enters the water pipe 36, and most of the water enters the return water tank 35 through the inlet pipe 38.

[0055] The gap between the conical cover 27 and the core drill bit 19 is very small.

[0056] The workflow of this invention is as follows: The precast slab is placed on the support plate 5, the screw 8 is rotated to fix the precast slab in place by the pressure block 9, and a sponge block is placed below the central hole 10 to prevent the cylindrical core from falling directly into the hard surface and being damaged when core extraction is completed. Clean water is added to the clean water tank 34.

[0057] The control motor 2 rotates intermittently. When motor 2 rotates, it drives the slide 12, vertical rod 13, guide shaft 14, intermediate transmission shaft 18, core drill bit 19, gear 22, gear 11, and gear 324 to rotate. The intermediate transmission shaft 18 drives the block 17 and cylinder 16 to revolve. Cylinder 16 drives sphere 15 to move along the spiral groove 47. Sphere 15 drives cylinder 16 and block 17 to move along the height direction. Block 17 drives the intermediate transmission shaft 18 to move along the guide shaft 14 and guide groove 23. The intermediate transmission shaft 18... The core drill bit 19 moves along the height direction. Gear 21 drives L-shaped rod 32 to rotate. L-shaped rod 32 drives ball 33 to reciprocate along annular groove 41. Ball 33 drives cylinder 40 to reciprocate. Cylinder 40 drives piston 39 to reciprocate. Gear 24 drives L-shaped rod 30 to rotate. L-shaped rod 30 drives ball 31 to reciprocate along annular groove 41. Ball 33 drives cylinder 42 to reciprocate. Cylinder 42 drives piston 44, U-rod 45, and conical plug 46 to reciprocate. This gradually increases the number of reciprocating rotations of motor 2, causing the core drill bit 19 to gradually drill downwards and extract core material from the precast slab.

[0058] Piston 39 reciprocates, and when it moves downward, it squeezes the air and water in the water tank 34, causing water to enter the water outlet pipe 28. Water is then sprayed from the water outlet pipe 28 onto the core drill bit 19. The number of teeth on gear 22 is much greater than that on gear 21, and the water spray interval on the water outlet pipe 28 is very small. The core drill bit 19 spirals down or up, causing water to spray onto the core drill bit 19, thus cooling the core drill bit 19. The water comes into contact with the core drill bit 19 during the core extraction process, generating dust. The water and dust mix to form wastewater, which falls into the area formed by the cooling tank 26 and the conical cover 27. Piston 44 reciprocates. When piston 44 moves upward, conical plug 46 enters water pipe 36. Under the action of piston 44, sewage enters round pipe 37 through water pipe 36. Most of the water enters return water tank 35 through inlet pipe 38 (the upper end of inlet pipe 38 is much higher than the bottom plate of return water tank 35). Substances insoluble in water, such as sand, are deposited in the area formed by water pipe 36 and conical plug 46. When piston 44 moves downward, conical plug 46 disengages from water pipe 36, and sand moves downward along the conical surface of conical plug 46 and falls down.

[0059] After core extraction is completed, control motor 2 to rotate, so that core drill bit 19 moves away from the precast slab and the precast slab is removed.

[0060] Driven by motor 2, the device enables the core drill bit 19 to rotate while spirally descending or rising under the limiting action of spiral groove 47. Water is sprayed out from water outlet pipe 28 to contact the spirally rising and falling core drill bit 19, increasing the contact area and improving the cooling effect.

[0061] The piston 39 of this device moves downward, compressing the air and water in the water tank 34, causing water to enter the outlet pipe 28. From the outlet pipe 28, water is sprayed onto the core drill bit 19. The converging water outlet 29 increases the water pressure, causing the water to impact the core drill bit 19 and fall into the area formed by the conical cover 27 and the cooling tank 26, preventing water from falling through the gap between the conical cover 27 and the core drill bit 19. The piston 44 moves reciprocally. When the piston 44 moves upward, the conical plug 46 enters the water pipe 36. After the piston 44... Under the action of 4, sewage enters the circular pipe 37 through the water pipe 36, and most of the water enters the return water tank 35 through the water inlet pipe 38 (the upper end of the water inlet pipe 38 is much higher than the bottom plate of the return water tank 35). Insoluble substances such as sand particles are deposited in the area formed by the water pipe 36 and the conical plug 46. When the piston 44 moves downward, the conical plug 46 moves downward and separates from the water pipe 36. The sand particles move downward along the conical surface of the conical plug 46 and fall down, realizing the recycling of water and the separation of insoluble sand particles.

[0062] This device, through its ingenious design, achieves the following: while the core drill bit 19 is drilling, the water comes into contact with the dust generated during the core drilling process, and the water and dust are mixed to suppress the dust. Then, the water and water-insoluble sand are separated, making it convenient to use.
