Description

Technical Field

[0001] The invention belongs to the technical field of processing equipment for concrete square piles, and in particular relates to a casting device for concrete square piles. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, is referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. During the construction of the pile foundation, concrete needs to be poured. During pouring, in order to remove the bubbles in the concrete, tamping is required to make the concrete densely combined, so as to eliminate the honeycomb surface of the concrete, improve the strength of the concrete, and ensure the quality of the pile foundation.

[0003] After searching, the patent with announcement number CN116716887B discloses a concrete bored pile casting device, which can effectively solve the problem in the prior art that as the subsequent concrete is continuously poured, the concrete inside the pile hole continues to rise, and the guide tube is lifted and gradually removed accordingly. Each time the guide tube is removed, the large hopper above it needs to be removed first. Since the large hopper is too large, each transfer is very troublesome. Moreover, when the large hopper is reset, its discharge hole and horizontality need to be calibrated and adjusted with the guide tube for multiple times. The finishing operation is cumbersome and not conducive to the continuous pouring of pile foundation concrete.

[0004] However, the concrete bored pile casting device is unable to perform preliminary vibration on the concrete during the casting process, resulting in the need to use a concrete vibrator to vibrate the concrete for a long time after the casting is completed, resulting in low construction efficiency.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] See also Figure 1-Figure 10A pouring device for concrete square piles, comprising a pouring box 1 and a defoaming assembly 2 and a force block 3 installed inside the pouring box 1, the pouring box 1 comprising a pouring box body 11, a hopper 12 arranged at the top of the pouring box body 11 and a discharge port 13 arranged at the bottom of the pouring box body 11; a defoaming assembly 2 for defoaming concrete is arranged on one side of the bottom end of the pouring box body 11 near the discharge port 13, the defoaming assembly 2 comprises a defoaming box 201 and a defoaming mechanism, the interior of the defoaming box 201 is hollow to form a first The first cavity 202 has a cavity 202 and a second cavity 203 symmetrically arranged with the first cavity 202. The first cavity 202 is slidably connected to a connecting rod 204. The connecting rod 204 drives the defoaming mechanism to vibrate and defoam the concrete by sliding inside the first cavity 202. A scraping mechanism for cleaning the connection between the connecting rod 204 and the defoaming box 201 is provided on the side of the surface of the defoaming box 201 close to the connecting rod 204. A force block 3 is fixedly connected to the connecting rod 204 on one side close to the casting box 1.

[0019] When in use, first move the casting box 1 to the inside of the pile foundation hole, then inject concrete into the casting box body 11 through the hopper 12 and flow into the bottom of the pile foundation hole through the discharge port 13, so that the concrete overflows the bottom of the defoaming box 201. In this process, when the concrete flows into the casting box body 11, it will first fall on the surface of the force-bearing block 3. The force applied to the surface of the force-bearing block 3 during the falling process of the concrete causes the force-bearing block 3 to press the connecting rod 204 to slide inside the first cavity 202, thereby squeezing the air inside the first cavity 202 into the inside of the second cavity 203, and then driving the defoaming mechanism to vibrate and defoam the concrete. The connecting rod 204 can drive the scraping mechanism to rotate when sliding, and clean the concrete that falls on the connection between the connecting rod 204 and the defoaming box 201 to prevent the sliding of the connecting rod 204 due to the solidification of the concrete.

[0020] See also Figure 2 , Figure 4 , Figure 7 and Fig. 9The defoaming mechanism includes a push rod 205 and an air intake structure. A piston 207 adapted to the first cavity 202 is arranged on one side of the push rod 205 close to the first cavity 202. A return spring 206 adapted to the piston 207 is arranged inside the first cavity 202. A limiting structure for limiting the piston 207 is arranged on one side of the first cavity 202 away from the connecting rod 204. The interior of the defoaming box 201 is hollow to form an air storage bin 210. The defoaming box 201 The interior of the defoaming box 201 is provided with an air inlet 211 and an air outlet 212 adapted to the air storage bin 210, the interior of the air storage bin 210 is fixedly connected with a first connecting spring 213, and a push plate 214 adapted to the air storage bin 210 is provided on the side of the first connecting spring 213 close to the air inlet 211, the interior of the defoaming box 201 is fixedly connected with an electric cylinder 215, and one end of the electric cylinder 215 is provided with a baffle 216 adapted to the air outlet 212, and the interior of the defoaming box 201 is provided with a push plate 214 adapted to the electric cylinder 215. 15 independently powered battery 217, the second cavity 203 is rotatably connected with a connecting shaft 221 inside, the surface of the connecting shaft 221 is fixedly connected with a turbine 222, one end of the connecting shaft 221 located on the outer wall of the defoaming box 201 is fixedly connected with a silicone strip 223, a rubber pad 224 adapted to the silicone strip 223 is arranged on the outer wall of the defoaming box 201, one end of the silicone strip 223 extending out of the surface of the rubber pad 224 is rotatably connected with a vibration tube 225, and a vibration convex block 226 adapted to the silicone strip 223 is arranged inside the vibration tube 225, a plurality of groups of grooves 208 are arranged on the surface of the connecting rod 204 along the circumferential direction, a sealing structure for blocking the grooves 208 is arranged inside the first cavity 202, the piston 207 is pushed to slide inside the first cavity 202 by the connecting rod 204, so that the air inside the first cavity 202 enters the inside of the second cavity 203, so that the turbine 222 drives the vibration convex block 226 to rotate and the vibration tube 225 vibrates.

[0021] When in use, when the connecting rod 204 slides downward, it will push the piston 207 to slide inside the first cavity 202. At this time, the external air enters the first cavity 202 through the vent hole 229, thereby squeezing the air inside the first cavity 202 into the interior of the gas storage bin 210 through the air inlet 211, so that the push plate 214 slides inside the gas storage bin 210 and squeezes the first connecting spring 213. When the piston 207 drops to the bottom of the first cavity 202, the limiting structure will limit the piston 207 and limit it at the bottom of the first cavity 202. The battery 217 independently powers the electric cylinder 215, so that the electric cylinder 215 pushes the baffle 216 to slide downward, thereby releasing the limit on the gas outlet 212. The push plate 214 is reset to its original position, and the first connecting spring 213 pushes the push plate 214 to return to its original position, thereby injecting the air inside the air storage bin 210 into the second cavity 203 through the air outlet 212. When the air blows toward the surface of the turbine 222, the turbine 222 will rotate, driving the connecting shaft 221 and the silicone strip 223 to rotate, thereby causing the vibration protrusion 226 to rotate inside the vibration tube 225. The vibration protrusion 226 rotates inside the vibration tube 225, causing the vibration tube 225 to vibrate inside the concrete, thereby breaking the bubbles inside the concrete. The flexibility of the silicone strip 223 can increase the vibration amplitude of the vibration tube 225, and the rubber pad 224 can protect the silicone strip 223 from being corroded by the concrete.

[0022] In order to reset the lowered connecting rod 204, refer to Figure 2 , Figure 7 and Fig. 9 The defoaming mechanism also includes a slide 227 adapted to the second cavity 203, and a plurality of through holes 228 are arranged on the surface of the slide 227 along the circumferential direction. A push rod 231 is slidably connected to the interior of the second cavity 203, and a plurality of vent holes 229 adapted to the first cavity 202 and the second cavity 203 are arranged on the surface of the defoaming box 201.

[0023] When in use, the top rod 231 will synchronously drop to the bottom of the second cavity 203 along with the connecting rod 204. Since the diameter of one end of the top rod 231 is smaller than the diameter of the second cavity 203, the top rod 231 will not squeeze the internal air of the second cavity 203 when it drops. When the surface of one end of the top rod 231 fits the surface of the sliding sheet 227, the through hole 228 will be blocked. At the same time, the external air will enter the second cavity 203 through the vent hole 229. When the air inside the air storage bin 210 enters the second cavity 203, the air inside the air storage bin 210 will enter the second cavity 203. 03, the slide 227 will push the top rod 231 to slide upward, so that the top rod 231 drives the connecting rod 204 to reset through the force block 3, so that the top rod 231 and one end of the connecting rod 204 block the vent 229. When the air inside the air storage bin 210 completely enters the second cavity 203, the slide 227 slides downward under the force, thereby releasing the limit on the through hole 228, so that when the slide 227 falls to the bottom of the second cavity 203, it will not squeeze the air inside the second cavity 203.

[0024] In order to enable the piston 207 to continue to squeeze the air when the connecting rod 204 is reset, please refer to Figure 8 The limiting structure includes a limiting spring 218, and a second limiting block 219 adapted to the piston 207 is arranged on the side of the limiting spring 218 close to the first cavity 202. A ventilation groove 220 adapted to the second limiting block 219 is arranged inside the defoaming box 201, and one end of the ventilation groove 220 is connected to the second cavity 203.

[0025] When in use, when the piston 207 descends to the bottom of the first cavity 202, the bottom end of the piston 207 will squeeze the inclined surface of the second limit block 219, thereby pushing the second limit block 219 to slide toward the inside of the defoaming box 201 and squeezing the limit spring 218. When the piston 207 descends to the bottom of the first cavity 202, the limit spring 218 will push the second limit block 219 to reset, thereby limiting the piston 207. After the push rod 231 is reset inside the second cavity 203, the air inside the second cavity 203 will enter the ventilation groove 220, thereby pushing the second limit block 219 to slide inside the defoaming box 201 and releasing the limit on the piston 207. After that, the reset spring 206 is forced to push the piston 207 to slide inside the first cavity 202, so that the push rod 205 slides back into the connecting rod 204.

[0026] In order to allow the space below the piston 207 to be refilled with air as the piston 207 rises, see Figure 7 and Fig.10The sealing structure includes an air vent 238. A plurality of air vents 238 are arranged on the surface of the piston 207 along the circumferential direction. A second connecting spring 239 is fixedly connected inside the air vent 238. A limiting plate 240 adapted to the air vent 238 is arranged on the side of the second connecting spring 239 away from the connecting rod 204. A positioning column 241 is fixedly connected to the surface of the limiting plate 240.

[0027] When in use, the connecting rod 204 can block the vent 229 when it rises, and the piston 207 will squeeze the air inside the first cavity 202 when it rises. The pressure exerted on the surface of the piston 207 by the air inside the first cavity 202 causes the air to enter the interior of the vent 238, thereby separating the limit plate 240 from the vent 238 and releasing the limit on the vent 238, so that the air above the piston 207 can flow to the bottom of the piston 207 through the vent 238. When the piston 207 rises to the top, the second connecting spring 239 can pull the limit plate 240 to reset and re-block the vent 229, and the positioning column 241 can play a positioning role in the movement of the limit plate 240.

[0028] See also Figure 5 and Figure 7 The scraping mechanism includes a first limit block 209, and a first limit block 209 adapted to the groove 208 is arranged on one side of the first cavity 202 close to the force-bearing block 3 along the circumferential direction of the inner periphery. A filter screen 230 adapted to the vent hole 229 is arranged on the surface of the defoaming box 201, and a threaded groove 232 is provided on the surface of the connecting rod 204. A rotating ring 233 is rotatably connected to the surface of the defoaming box 201, and a protrusion 234 adapted to the threaded groove 232 is arranged on the inner wall of the rotating ring 233. A plurality of groups of brushes 235 adapted to the filter screen 230 are arranged along the circumferential direction on the outer periphery of the rotating ring 233, and a plurality of groups of scrapers 236 are fixedly connected to the surface of the rotating ring 233, and an inclined surface 237 is arranged on the surface of the scraper 236.

[0029] When in use, the thread groove 232 is engaged with the protrusion 234 inside the rotating ring 233, so that the connecting rod 204 drives the rotating ring 233 to rotate when moving, thereby driving the brush 235 to clean the concrete attached to the surface of the filter screen 230. As the connecting rod 204 rises and falls, the protrusion 234 can clean the concrete inside the thread groove 232 and cooperate with the scraper 236 to scrape the concrete on the surface of the connecting rod 204. Then, through the rotation of the rotating ring 233 and the inclination of the surface of the scraper 236, the concrete on the surface of the connecting rod 204 can be removed. The surface 237 can shake off the scraped concrete, and when the connecting rod 204 rises and closes the groove 208 and the first limit block 209, the groove 208 can be limited. At this time, the connecting rod 204 continues to rise, so that the connecting rod 204 squeezes the air inside the first cavity 202 and discharges it to the outside of the defoaming box 201 through the vent 229. In this process, the concrete adhering to the surface of the filter screen 230 can be blown off to prevent the filter holes on the surface of the filter screen 230 from being blocked due to the solidification of the concrete.

[0030] See also Figure 6 The force-bearing block 3 includes a force-bearing block body 31 located directly below the feed opening 13, a material storage groove 32 is provided on one side of the force-bearing block body 31 close to the feed opening 13, a conical block 33 is fixedly connected to the inner center of the material storage groove 32, and a feed opening groove 34 is provided along the circumferential direction on the inner periphery of the force-bearing block body 31.

[0031] During use, when concrete falls onto the surface of the force-bearing block 3, it will fill up the interior of the storage trough 32, and cooperate with the force applied to the surface of the force-bearing block body 31 during the falling process of the concrete to make the force-bearing block body 31 press the connecting rod 204 to slide inside the first cavity 202. After that, the concrete can be evenly distributed to the four sides of the storage trough 32 through the conical block 33, and finally discharged through the discharge trough 34.
