Description

Technical Field

[0001] This invention belongs to the field of pipe pile technology, and particularly relates to a device and method for processing and forming a perforated pipe pile model. Background Technology

[0002] To mitigate the adverse effects of excess pore water pressure during static pressure pile driving, engineering projects often employ measures such as setting stress relief holes, rationally arranging the pile driving sequence, and controlling the pile driving rate. However, these measures address the external environment of the pile body and do not consider the pile body itself. Engineering practice shows that static pressure pile driving on soft soil foundations suffers from a significant soil squeezing effect. This is mainly because the gas and liquid in the soil surrounding the pile cannot be released in time during the pile driving process, leading to displacement of the surrounding soil and damage to the site environment. Patent ZL201020105398.2 proposes a PTC-type perforated pipe pile technology for deep soft soil foundation treatment. This technology effectively reduces excess pore water pressure in the soil surrounding the pile throughout the entire pile driving process by optimizing the perforation design of the pile body structure, thereby improving the shear strength of the soil and the bearing capacity of the foundation, and achieving the goal of reducing the soil squeezing effect of pipe pile driving.

[0003] During the manufacturing process of perforated pipe piles, drilling is usually required. Uneven force applied during drilling can easily cause burrs on the pile body, and in severe cases, may even cause cracks in the pile body, leading to a significant increase in production costs. To address this problem, a pipe pile model processing device is proposed that can simultaneously remove burrs caused by drilling during the drilling process. Summary of the Invention

Beneficial effects

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] 1. Through the embodiments of the present invention, the relevant technicians insert the pipe pile into the drilling assembly, causing the bottom surface of the pipe pile to push the telescopic rod downward, so that the telescopic rod enters the sleeve, thereby causing the telescopic rod to drive the hinge seat on it to move synchronously, thereby causing one end of the second connecting rod to move synchronously downward, causing the second connecting rod and the first connecting rod to push the push plate to move to both sides, thereby causing the push plate to drive the drilling nail fixedly connected to it to start moving synchronously, thereby causing the drilling nail to drill a hole in the pipe pile. At the same time, the push plate abuts against the inner wall of the pipe pile to prevent the pipe pile from falling. The relevant technicians control the guide rod to start rotating, thereby causing the two guide rods to cooperate to drive the conveyor belt to start rotating, thereby causing the sleeve fixedly connected to the conveyor belt to start moving linearly, thereby driving the pipe pile on it to move synchronously.

[0019] 2. According to the embodiments of the present invention, when the guide rod starts to rotate, it drives the first pulley fixedly connected to its top to rotate synchronously, thereby causing the fourth pulley to rotate synchronously with the first pulley under the cooperation of the first chain. This causes the fourth pulley to drive the eccentric disk fixedly connected to it to rotate synchronously, causing the eccentric disk to drive the connecting rod fixedly connected to it to move synchronously, thereby causing the connecting rod to start linear reciprocating motion under the constraint of the limit ring. This causes the connecting rod to drive the cutter head fixedly connected to it to start moving synchronously, thereby causing the cutter head to groove the surface of the pipe pile. When the eccentric disk rotates, it drives the fifth pulley fixedly connected to it to move synchronously, thereby causing the third pulley to rotate synchronously with the fifth pulley under the cooperation of the second chain. This causes the third pulley to drive the first shaft fixedly connected to it to move synchronously, thereby causing the first shaft to drive the shaft gear fixedly connected to it to move synchronously, causing the shaft gear to drive the internal gear meshing with it to rotate, thereby causing the internal gear to rotate on its own axis while revolving around the shaft gear under the cooperation of the external gear. This causes the rotating rod fixedly connected to the internal gear to rotate synchronously, thereby causing the rotating rod to drive the grinding stone to rotate synchronously, causing the grinding stone to polish the surface of the pipe pile and reduce the burrs on the surface of the pipe pile.

[0020] 3. In this embodiment of the invention, when the first shaft rotates, it drives the second pulley fixedly connected to it to rotate synchronously. The sixth pulley, in cooperation with the third chain, moves synchronously with the second pulley. This causes the sixth pulley to drive the second shaft fixedly connected to it to move synchronously, which in turn drives the first worm gear fixedly connected to it to rotate synchronously. The first worm gear then drives the fan blade fixedly connected to its top to rotate synchronously. The rotating fan blade generates wind pressure that blows away the powder generated on the surface of the pipe pile during processing. The first worm gear drives the first worm wheel meshing with it to rotate synchronously, which in turn drives the guide rod fixedly connected to it to rotate synchronously. The guide rod then drives the second worm gear fixedly connected to it to rotate synchronously, which in turn drives the second worm wheel meshing with it to start rotating. This causes the second worm wheel to drive the shaft fixedly connected to it to rotate synchronously, which in turn drives the fan blade fixedly connected to it to start rotating, thereby increasing the dust removal efficiency.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1-7 The present invention provides a perforated pipe pile model processing and forming device and forming method, including a shell 101 and a drilling assembly 3.

[0034] The drilling assembly 3 includes a sleeve 301, a telescopic rod 302, a first connecting rod 303, and a second connecting rod 304. One end of the telescopic rod 302 is slidably connected to the sleeve 301. A hinge seat is fixedly connected to the sleeve 301 and the telescopic rod 302 respectively. The first connecting rod 303 and the second connecting rod 304 are respectively hinged to the hinge seat. The first connecting rod 303 and the second connecting rod 304 are hinged to each other. The sleeve 301 is connected to the transmission assembly 2.

[0035] Specifically, the other end of the first connecting rod 303 is hinged to a second hinge seat 306, the other end of the second connecting rod 304 is hinged to a first hinge seat 305, a push plate 308 is fixedly connected to the first hinge seat 305, a slide rail 307 is fixedly connected to the push plate 308, the second hinge seat 306 is slidably connected to the slide rail 307, and a drill pin 309 is fixedly connected to the push plate 308.

[0036] In this embodiment of the invention, the transmission component 2 includes a guide rod 201, a conveyor belt 202, a first pulley 203, and a first wheel chain 204. The conveyor belt 202 is fixedly connected to the sleeve 301, the guide rod 201 is rotatably connected to the housing 101, a roller is fixedly connected to the guide rod 201, the roller is drivenly connected to the conveyor belt 202, the first pulley 203 is fixedly connected to both ends of the guide rod 201, the first pulley 203 is drivenly connected to the first wheel chain 204, and the first wheel chain 204 is connected to the engraving component 5.

[0037] Based on the above, the relevant technicians, by inserting the pipe pile into the drilling assembly 3, cause the bottom surface of the pipe pile to push the telescopic rod 302 downward, so that the telescopic rod 302 enters the sleeve 301. This causes the telescopic rod 302 to drive the hinge seat on it to move synchronously, thereby causing one end of the second connecting rod 304 to move synchronously downward. This causes the second connecting rod 304 and the first connecting rod 303 to push the push plate 308 to move to both sides, thereby causing the push plate 308 to drive the drilling nail 309 fixedly connected to it to start moving synchronously. This allows the drilling nail 309 to drill holes in the pipe pile. At the same time, the push plate 308 abuts against the inner wall of the pipe pile to prevent the pipe pile from falling. The relevant technicians then control the guide rod 201 to start rotating, so that the two guide rods 201 cooperate to drive the conveyor belt 202 to start rotating, thereby causing the sleeve 301 fixedly connected to the conveyor belt 202 to start moving linearly, thereby driving the pipe pile on it to move synchronously.

[0038] In one embodiment of the present invention, the engraving assembly 5 includes an eccentric disk 501, a fourth pulley 502 and a connecting rod 505. The eccentric disk 501 is rotatably connected to the housing 101. The fourth pulley 502 is fixedly connected to the eccentric disk 501. The fourth pulley 502 is driven by the first wheel chain 204. The connecting rod 505 is rotatably connected to the guide rod on the eccentric disk 501.

[0039] Specifically, the connecting rod 505 is slidably connected to the limiting ring 506 in the limiting ring 506. Connecting rods 507 are fixedly connected to both sides of the limiting ring 506. The connecting rods 507 are fixedly connected to the housing 101. The bottom of the connecting rod 505 is fixedly connected to the cutter head 508. The fifth pulley 503 is fixedly connected to the shaft of the eccentric disk 501. The fifth pulley 503 is connected to the second wheel chain 504 for transmission. The second wheel chain 504 is connected to the grinding assembly 4.

[0040] In this embodiment of the invention, the grinding assembly 4 includes a first shaft 401, a second pulley 402, a third pulley 403, and a spindle gear 404. The first shaft 401 is rotatably connected to the housing 101. The second pulley 402 and the third pulley 403 are fixedly connected to the first shaft 401. The second pulley 402 is connected to the fan blade assembly 6. The second wheel chain 504 is connected to the third pulley 403. The spindle gear 404 is fixedly connected to the first shaft 401.

[0041] Specifically, an internal gear 405 meshes with one side of the shaft gear 404, the internal gear 405 meshes with an external gear 406, the external gear 406 is fixedly connected to the housing 101, the internal gear 405 is fixedly connected to the rotating rod 407, a frame 408 is rotatably connected to the bottom of the rotating rod 407, the frame 408 is rotatably connected to the first shaft 401, and a grinding stone 409 is fixedly connected to the top of the rotating rod 407.

[0042] As described above, when the guide rod 201 starts to rotate, it drives the first pulley 203 fixedly connected to its top to rotate synchronously. This causes the fourth pulley 502 to rotate synchronously with the first pulley 203 under the cooperation of the first chain 204. The fourth pulley 502 then drives the eccentric disk 501 fixedly connected to it to rotate synchronously. The eccentric disk 501 then drives the connecting rod 505, which is rotatably connected to it, to move synchronously. Under the constraint of the limiting ring 506, the connecting rod 505 begins to perform linear reciprocating motion, causing the cutterhead 508 fixedly connected to it to move synchronously, thus enabling the cutterhead 508 to groove the surface of the pipe pile. When the eccentric disk 501 rotates, it drives the fifth pulley 503 fixedly connected to it to move synchronously. The third pulley 403, in conjunction with the second chain 504, rotates synchronously with the fifth pulley 503. This causes the third pulley 403 to drive the first shaft 401, which is fixedly connected to it, to move synchronously. The first shaft 401 then drives the shaft gear 404, which is fixedly connected to it, to move synchronously. The shaft gear 404 then drives the internal gear 405, which meshes with it, to rotate. The internal gear 405, in conjunction with the external gear 406, rotates on its own axis while revolving around the shaft gear 404. This causes the rotating rod 407, which is fixedly connected to the internal gear 405, to rotate synchronously. The rotating rod 407 then drives the grinding stone 409 to rotate synchronously, allowing the grinding stone 409 to polish the surface of the pipe pile and reduce burrs on the surface.

[0043] In one embodiment of the present invention, the fan blade assembly 6 includes a second shaft 601, a sixth pulley 602 and a third chain 603. The second shaft 601 is rotatably connected to the housing 101. The sixth pulley 602 is fixedly connected to the second shaft 601. The sixth pulley 602 is drive-connected to the third chain 603. The third chain 603 is drive-connected to the second pulley 402.

[0044] In this embodiment of the invention, a first worm gear 604 is fixedly connected to the second shaft 601, a fan blade 606 is fixedly connected to the top of the second shaft 601, a first worm wheel 605 is meshed with the lower side of the first worm gear 604, the first worm wheel 605 is fixedly connected to the guide rod 607, and the guide rod 607 is rotatably connected to the housing 101.

[0045] Specifically, a plurality of second worm gears 6071 are fixedly connected to the guide rod 607, and a second worm wheel 609 is meshed on the second worm gear 6071. The second worm wheel 609 is fixedly connected to the shaft 608, the shaft 608 is rotatably connected to the housing 101, and a fan blade 606 is fixedly connected to the top end of the shaft 608.

[0046] In view of the above, when the first shaft 401 rotates, it drives the second pulley 402 fixedly connected to it to rotate synchronously, so that the sixth pulley 602 moves synchronously with the second pulley 402 in cooperation with the third chain 603. This causes the sixth pulley 602 to drive the second shaft 601 fixedly connected to it to move synchronously, which in turn drives the first worm gear 604 fixedly connected to it to rotate synchronously. This, in turn, causes the first worm gear 604 to drive the fan blade 606 fixedly connected to its top to rotate synchronously. The rotation of the fan blade 606 generates wind pressure that blows off the processed material from the surface of the pipe pile. The raw powder is generated by the first worm gear 604 driving the first worm wheel 605 meshing with it to rotate synchronously. This causes the first worm wheel 605 to drive the guide rod 607 fixedly connected to it to rotate synchronously. The guide rod 607 then drives the second worm gear 6071 fixedly connected to it to rotate synchronously. This causes the second worm gear 6071 to drive the second worm wheel 609 meshing with it to rotate. This causes the second worm wheel 609 to drive the shaft 608 fixedly connected to it to rotate synchronously. This causes the shaft 608 to drive the fan blade 606 fixedly connected to it to rotate, thereby increasing the dust removal efficiency.

By controlling the first guide rod (201) to start rotating, the two first guide rods (201) cooperate with each other to drive the conveyor belt (202) to start rotating. This causes the sleeve (301) fixedly connected to the conveyor belt (202) to start moving linearly, driving the pipe pile on it to move synchronously.
