Description

Technical Field

[0001] The invention relates to the technical field of pile driving equipment, and in particular to a coiled type intelligent pile driving machine. Background Art

[0002] At present, grouting operations are required during the drilling construction process. The existing pile pouring operations mainly rely on cranes, pouring platforms and multi-section iron conduits. The multi-section iron conduits are connected to 30-50cm from the bottom of the hole through threaded connections and rubber ring seals. During pouring, concrete is delivered to the bottom of the hole through the sealed iron conduit to ensure that when the burial depth reaches 6 meters, the conduit is pulled out through multiple manual measurements and verifications to ensure that the burial depth is not less than 2 meters. The operation is circulated in sequence to meet the designed pouring requirements, and concrete is continuously poured through the ash hopper. The pressure difference of concrete inside and outside the conduit is used to achieve continuous concrete pouring.

[0003] However, in the prior art, a crane is required to circulate and connect the conduits in sequence during pouring, and during the installation process, manpower is needed to connect the conduits and tighten the conduit threads. The crane lifts the conduit and then lowers it. During this process, the platform door is opened and closed manually. This process is all manually operated, the labor intensity of the workers is high, and the labor cost is high.

[0004] At the same time, manual labor is required during the reversal and lifting of the pipes, which can easily cause harm to the operators. The crane is lifting heavy objects and it is easy to hit nearby operators when rotating, causing harm to the operators. During the disassembly and installation of the pipes, the heavy weight of the iron pipes can easily bump into the operators, causing personal harm to the operators. During the grouting process, the mud has a wall protection and anti-collapse effect on the hole, but accidental hole collapse may occur. Operators can only operate above the hole mouth. Once an accidental hole collapse occurs, it will cause serious personal injury.

[0005] In addition, since the metal conduits are connected manually, each section of the conduit may have loose threads or damaged sealing rings during connection, causing air and water leakage, which affects the quality of pile pouring. The concave part of the conduit will cause wear and leakage due to long-term friction with the concrete, which is difficult to check and causes air and water leakage, affecting the quality of pile pouring. In the existing pile pouring process, the measurement of concrete height and the calculation of the buried depth of the conduit are all manual operations, which may cause miscalculations, resulting in excessive or insufficient pulling of the conduit, seriously affecting the quality of pile pouring. Accidents occur where concrete cannot be poured in or even pipes are blocked. Moreover, if there are no experienced full-time personnel to perform frequent measurements with a special measuring rope during the pouring process, and accurately calculate whether the next step is needed based on the measured data, the quality of pile pouring is greatly affected by human factors in this process.

[0006] During the pouring process, the site requirements are relatively strict because a crane is needed to cooperate with the operation, so the requirements for the site are relatively high. If the site cannot meet the construction requirements of the crane, a forklift excavator is needed to level the site. The requirements for the working environment are relatively high. For example, if the high-altitude obstacles cannot meet the construction requirements of the crane, and the site is too soft, it may cause production to stop; during the construction, the pile foundation construction of the pier (platform) position needs to be cross-operated, and the pouring tools (conduit, platform, etc.) need to be transported backwards. The transportation is cumbersome and the efficiency is too low, which does not meet the requirements of modern high-efficiency production. Summary of the invention

[0007] (1) The technical problem to be solved by the present invention is: in the existing pile pouring process, a crane, a pipe and a pouring platform are used to cooperate in the operation, and the pressure difference of concrete inside and outside the pipe is used to achieve continuous concrete pouring; there are problems such as high work intensity, low work efficiency, great safety hazards for workers, the pouring quality is greatly affected by human factors, high requirements for the construction site, high cost, and cumbersome transportation of equipment.

DETAILED DESCRIPTION

[0037] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] like Figures 1 to 10 As shown, an embodiment of the present invention provides a coiled intelligent pile driver, comprising a base 1, a walking device 11, a coiling device 12, a delivery hose 15, a metal connecting pipe 16, a high-pressure delivery device 13 and a lifting arm 14; the walking device 11 is connected to the lower side of the base 1, and is used to drive the entire coiled intelligent pile driver to move; the coiling device 12, the high-pressure delivery device 13 and the lifting arm 14 are all arranged on the base 1; the lower end of the lifting arm 14 is fixedly connected to the base 1, and the upper end of the lifting arm 14 is provided with a positioning wheel 1421; one end of the delivery hose 15 is connected to the coiling device 12, and the other end bypasses the positioning wheel 1421 and is connected to the metal connecting pipe 16; the coiling device 12 can rotate, and is used to retract and release the delivery hose 15; the high-pressure delivery device 13 is connected to the delivery hose 15, and is used to transport concrete into the delivery hose 15.

[0039] In the prior art, pile pouring is performed by using the pressure difference between the inside and outside of a free fall body, so a metal conduit is required. Since the pressure difference between the inside and outside is relatively small, if a hose is used, it is easy for the pipe to be blocked due to insufficient pressure and pile pouring cannot occur. In order to meet the requirements of continuous pile pouring, the prior art uses multiple sections of metal conduits for connection, and then the metal conduits are dropped by the boom 142, and then concrete is continuously poured with a hopper to achieve continuous pile pouring. In order to meet the requirements of transportation and lifting, the metal conduit cannot be a whole section, but is composed of multiple sections. During the connection process, a crane is needed to lift the metal conduit, and then the operator manually tightens the thread. The labor intensity of the workers is high, the labor cost is high, and the operators are in danger during the installation process.

[0040] The coiled intelligent pile driving machine provided in the present application adopts a high-pressure delivery device 13 to replace the traditional free-fall body internal and external pressure difference injection. The high-pressure delivery device 13 can provide sufficient pressure for concrete. Therefore, the delivery hose 15 can meet the pressure demand for pile injection, and there will be no situation where the delivery hose 15 is blocked by insufficient pressure concrete, so the concrete pile injection operation can be carried out continuously and stably.

[0041] The use of the delivery hose 15 replaces the conventional metal conduit and eliminates the process of disassembling and assembling section by section, greatly saving operation time, reducing labor intensity, and increasing work efficiency. At the same time, it also avoids the danger of operators in the process of connecting the delivery hose 15. Since the continuous delivery hose 15 is used, there is no need to frequently disassemble and assemble the conduit section by section, which eliminates the leakage caused by loose threads and loose seals, reduces the probability of broken piles, and improves the quality of pile pouring. In addition, the coiled intelligent pile driving machine provided in this embodiment no longer requires a crane to cooperate with the operation, omits the reverse transportation and hoisting processes, eliminates safety hazards, and saves the cost of crane rental. In this embodiment, concrete is poured through a high-pressure conveying device 13, replacing the conventional free fall body internal and external pressure difference type pouring, so as to avoid the phenomenon of pouring failure and pipe blockage caused by small pressure difference or concrete quality not meeting the standard when leaving the factory. The coiled intelligent pile driving machine provided in this embodiment is an integrated machine that occupies a relatively small working surface and has low requirements for the working environment. It can be said to be an all-terrain pile driving machine. At the same time, it can be conveniently operated and moved through the walking device 11, which solves the problem of cumbersome and inefficient transportation of devices such as cranes and metal conduits in the prior art.

[0042] According to one embodiment of the present invention, Figures 1 to 4 As shown, the winding device 12 includes a drum 121 and a hydraulic motor 122 for driving the drum 121 to rotate; two conveying hoses 15 are provided, both of which are wound on the drum 121, and both of which are connected to the metal connecting pipe 16, and the high-pressure delivery device 13 is connected to the two conveying hoses 15 respectively. The drum 121 is similar to the drum 121 for winding steel wire ropes in the prior art, and outer resistance frames 123 are provided on opposite sides of the drum 121. A ring groove is formed between the two outer resistance frames 123 and the outer wall surface of the drum 121, and the conveying hose 15 is fixed in the ring groove to prevent the conveying hose 15 from being separated from the drum 126 during the rolling process of the drum 121, thereby limiting the conveying hose 15. The hydraulic motor 122 is used to drive the drum 121 to rotate, and the drum 121 rotates to realize the retraction and release of the conveying hose 15 wound on the drum 121.

[0043] like Figures 6 to 8As shown, two oppositely arranged vertical plates 125 are fixed on the base 1, the reel 121 is located between the two vertical plates 125, and the two vertical plates 125 are correspondingly provided with through holes 1251.

The roller 126 and the reel 121 are welded and fixed as a whole through a first connecting plate 1261. The hydraulic motor 122 is located on the outer side of the vertical plate 125, and the output end of the hydraulic motor 122 passes through the through hole 1251 is communicated with the reducer 124, the reducer 124 is located in the drum 126, the reducer 124 and the drum 126 are welded and fixed by a second connecting plate 1262, and a transmission pipeline 1263 is coaxially arranged in the drum 126, the transmission pipeline 1263 is fixedly connected to the drum 126 through the second connecting plate 1262, the drum 126 is connected and fixed to the transmission pipeline 1263 through the second connecting plate 1262, and then the transmission pipeline 1263 passes through another second The connecting plate 1262 is connected to the rotary joint 18. Specifically, the second connecting plate 1262 is fixedly connected to the first fixed flange 1267. The first fixed flange 1267 is connected to the transmission pipeline 1263 as a whole. A bearing 182 structure is provided between the other connecting plate and the transmission pipeline 1263. The fixed flange is connected to the bearing outer ring 1265. The bearing inner ring 1264 is sleeved on the outside of the transmission pipe and fixedly connected to the second fixed flange 127. The second fixed flange 127 is located on the vertical plate. 125 is arranged on the outer side of the vertical plate 125; an elbow connecting pipe 1266 is provided on the transmission pipeline 1263, and the elbow connecting pipe 1266 is communicated with the transmission pipeline 1263, and at the same time, the elbow connecting pipe 1266 passes through the roller 126 and the reel 121 and extends into the annular groove and is communicated with one end of the conveying hose 15, wherein the elbow connecting pipe 1266 is sealedly connected to the roller 126, and the bypass pipeline 135 is communicated with the conveying hose 15 through the swivel joint 18.

[0044] like Fig. 9As shown, the swivel joint 18 includes an outer guide ring 183, a bearing 182, a bearing end cover 185, a bearing outer retaining ring 184, and a hollow cylindrical inner guide ring 181. One end of the inner guide ring 181 is provided with a first connecting flange 1811. The outer guide ring 183 is sleeved on the outer side of one end of the inner guide ring 181 away from the first connecting flange 1811. The end of the outer guide ring 183 away from the first connecting flange 1811 is provided with a second connecting flange 1831. The bearing outer retaining ring 184 is sleeved on the outer side of the inner guide ring 181. One end of the bearing outer retaining ring 184 is connected to the end of the outer guide ring 183 away from the second connecting flange 1831. The other end of the bearing outer retaining ring 184 is against the bearing end cover 185. An installation cavity is formed between the bearing outer retaining ring 184, the bearing end cover 185, the inner guide ring 181 and the outer guide ring 183, and the bearing 182 is installed in the installation cavity. Figure 6 As shown, two bearings 182 are arranged in the installation cavity, a positioning ring 1821 is arranged between the two bearings 182, a dust ring 1822 is arranged between the bearing 182 and the second connecting flange 1831, and a sealing ring 1832 is arranged between the inner guide ring 181 and the outer guide ring 183. The positioning ring 1821 is used to limit the installation position of the bearing 182, so that the installation of the bearing 182 is more convenient, and the axial movement of the bearing 182 along the inner guide ring 181 can also be limited. The hollow part of the inner guide ring 181 is connected with the transmission pipeline 1263, and the transmission pipeline 1263 is fixedly and sealedly connected with the first connecting flange 1811. The second connecting flange 1831 is connected with the high-pressure delivery device 13 through the first connecting head 1351, and the second connecting flange 1831 is connected with the bypass pipeline 135 of the high-pressure delivery device 13 through the first connecting head 1351.

[0045] According to one embodiment of the present invention, Figure 5As shown, the high-pressure delivery device 13 includes a hydraulic cylinder 132, a delivery cylinder 133, a water tank 134, a bypass pipeline 135 and an open box 131, one end of the hydraulic cylinder 132 is connected to the box 131, and the other end is connected to the water tank 134, one end of the delivery cylinder 133 is connected to the water tank 134, and the other end is connected to the hydraulic power source; one end of the bypass pipeline 135 is connected to the box 131, and the other end is connected to the delivery hose 15; optionally, the other end of the box is connected to the delivery hose 15 through the first connector 1351, the inner guide ring 181, the transmission pipeline 1263 and the elbow connection pipe 1266; The hydraulic power source is an oil pump, which drives the delivery cylinder 133 to do reciprocating motion. The water tank 134 is filled with hydraulic oil, and the hydraulic cylinder 132 is driven to do reciprocating motion through the water tank 134, and then the high-pressure delivery device 13 delivers concrete to the delivery hose 15; wherein the box body 131 is equipped with a high-pressure delivery pump, and the high-pressure delivery pump is driven to operate by the hydraulic cylinder 132. At the same time, since the box body 131 is an open structure, concrete can be continuously injected into the box body 131 through equipment such as a ash hopper and a grouting tank. The concrete injected into the box body 131 enters the delivery hose 15 through the bypass line 135 under the drive of the high-pressure pump, thereby realizing high-pressure delivery of concrete.

[0046] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the coiled intelligent pile driver also includes a water tank and a vibrating slag removal device. The water tank 19 is connected to the high-pressure delivery device 13 through a pipeline. The vibrating slag removal device 191 is arranged on the water tank 19 and is connected to the water tank 19. The coiled cleaning intelligent pile driver provided in this embodiment also includes a water tank 19 and a vibrating slag removal device 191. The water tank 19 can supply water to the high-pressure delivery device 13 during normal operation. Since the delivery hose 15 is used for pile pouring, the delivery hose 15 can be bent. Therefore, when the delivery hose 15 is cleaned after the pile pouring is completed, one end of the delivery hose 15 can be inserted into the vibrating slag removal device 191. The solid particles in the sewage are filtered through the vibrating slag removal device 191. The filtered clean water enters the water tank 19 and can be used as the water source of the high-pressure delivery device 13 during the next pile pouring operation. This can avoid the sewage from being directly discharged to the construction site, causing damage to the construction site, and meet the concept of environmental protection construction. At the same time, the clean water can also be reused, reducing the waste of water resources and saving the use cost.

[0047] like Figures 1 to 4As shown, the lifting arm 14 includes a mounting seat 141, a suspension arm 142 and a hydraulic rod 143; the lower end of the mounting seat 141 is fixed on the base 1, and the lower end of the suspension arm 142 is rotatably connected to the upper end of the mounting seat 141; the lower end of the hydraulic rod 143 is connected to the base 1, and the upper end is connected to the suspension arm 142, which is used to drive the suspension arm 142 to rotate, so as to drive the upper end of the suspension arm 142 to move up and down. The suspension arm 142 on the lifting arm 14 can rotate around one end rotatably connected to the mounting seat 141 under the drive of the hydraulic cylinder 132, thereby realizing the up and down movement of the upper end of the suspension arm 142, wherein since the upper end of the suspension arm 142 is provided with a positioning wheel 1421, the delivery hose 15 is wound around the positioning wheel 1421, so that the delivery hose 15 can be driven to move up and down, and if there is an obstacle in the sky, it can be adjusted according to the height of the obstacle in the sky.

[0048] According to one embodiment of the present invention, Figures 1 to 4 As shown, the coiled intelligent pile driver also includes a controller, a hoisting device 17 and a distance sensor 161; the hoisting device 17 is used to hoist the metal connecting pipe 16 through a wire rope; Fig.10 As shown, the distance sensor 161 is arranged on the metal connecting pipe 16, and is used to detect the distance between the metal connecting pipe 16 and the concrete liquid level at the bottom of the hole, and send the detected distance signal to the hoisting device 17. The controller controls the hoisting device 17 to rotate according to the received distance signal. In this embodiment, the sensor is arranged at the upper end of the metal connecting pipe 16. The metal connecting pipe 16 is 6 meters long and weighs about 3 tons. The reason for using the metal connecting pipe 16 is to avoid floating during the pouring process due to the specific gravity of concrete being greater than that of the hose. The 6-meter length is determined according to the provisions of the "Underwater Cast-in-place Pile Regulations" that the concrete burial depth is 3-6 meters. At the same time, this section of the connecting pipe is buried in the concrete during the entire pouring process. The use of a metal pipe can extend the service life. The sensor can detect the distance between the metal connecting pipe 16 and the bottom of the hole, and then control the winch 17 to rotate, drive the metal connecting pipe 16 to lift up, so that the metal connecting pipe 16 can follow up in real time with the progress of pile pouring. The controller can control the coiling device 12 to rotate according to the received distance signal, so as to follow up the delivery hose 15 in real time. During the pouring process, the delivery hose 15 and the metal connecting pipe 16 can follow up in real time until the accurate measurement is made, effectively eliminating the accident of pipe jamming and pipe blocking caused by excessive artificial burial depth in conventional pouring, and can accurately lower the pipe to the bottom elevation required by the design, reducing human participation and achieving real-time control, and also avoiding the operator's measurement at the hole mouth and the accidental hole collapse causing casualties.

[0049] like Figure 2 and Figure 4As shown, the hoisting device 17 includes a driving wheel 171 and a driven wheel 172; the driving wheel 171 is rotatably connected to the lower end of the boom 142, and the driven wheel 172 is rotatably connected to the upper end of the boom 142. One end of the wire rope is fixed to the driving wheel 171, and the other end passes through the driven wheel 172 and is connected to the metal connecting pipe 16; optionally, as Figure 2 and Figure 4 As shown, two of the driving wheels 171 and the driven wheels 172 are provided. The two driving wheels 171 are provided on opposite sides of the lower end of the boom 142, and the two driven wheels 172 are provided on opposite sides of the upper end of the boom 142. The driving wheel 171 rotates under the drive of the motor to drive the wire rope to rotate around the driven wheel 172. The wire rope is connected to the metal connecting pipe 16, thereby realizing the lifting and lowering of the metal connecting pipe 16. The metal connecting pipe 16 can also be lifted and supported by the wire rope.

[0050] like Figure 1 and Figure 2 As shown, the walking device 11 is a hydraulic crawler walking mechanism, and a cab 2 is also provided on the base 1. The base 1 is also provided with an engine, an oil pump, and a high-pressure air pump assembly. The operator can drive the coiled intelligent pile driving machine provided by the present application for transfer, thereby avoiding the problem of inconvenient transportation of equipment such as metal pipelines in the prior art. Since the walking device 11 is a road belt walking mechanism, the requirements for the site ground (such as soft soil ground, muddy ground, rainy and snowy weather, etc.) are not high, and the production is not delayed, which saves the cost of renting a crane.

The concrete in the transmission pipeline 1263 enters the delivery hose 15 through the elbow connecting pipe 1266 under the action of high pressure. At the same time, since the first connector 1351 is connected with the transmission pipeline 1263 through the swivel joint 18, the hydraulic motor 122 is connected with the reducer 124 in transmission connection, and the reducer 124 is welded and fixed to the roller 126 through the second connecting plate 1262. The roller 126 is welded to the reel 121 as a whole through the first connecting plate 1261, so that the reel can be driven by the reducer 124 121 rotates, and the roller 126 is connected to the transmission pipeline 1263 through another second connecting plate 1262, so the transmission pipeline 1263 rotates synchronously with the roller 126, and the end of the transmission pipeline 1263 is fixedly connected to the first connecting flange 1811 of the swivel joint 18 through a flange, so as to realize the communication between the inner guide ring 181 and the transmission pipeline 1263, and the connection and fixation between the transmission pipeline 1263 and the entire swivel joint 18, and the transmission pipeline 1263 drives the first connecting flange 1811 to rotate, thereby driving the inner guide ring 181 to rotate, and the outer wall surface of the inner guide ring 181 is provided with a bearing 182 and a bearing The outer retaining ring 184, the bearing outer retaining ring 184 and the outer guide ring 183 are fixedly connected as a whole, so the inner guide ring 181 and the outer guide ring 183 rotate relative to each other through the action of the bearing 182, but the outer guide ring 183 does not rotate with the inner guide ring 181, and the outer guide ring 183 is connected to the bypass pipe 135 through the first connector 1351, so that the winding device 12 can drive the conveying hose 15 to rotate, and the bypass pipe will not generate torque as the winding device 12 rotates, which will cause the problem that the winding pipe cannot be fixed, and it can ensure that the high-pressure conveying device 13 can continuously convey concrete to the conveying hose 15.
