Description

Technical Field

[0001] The present application relates to the technical field of pile driving, and particularly to a pile foundation composite construction device for wharves. Background Art

[0002] In the construction project of a wharf, pile foundation construction plays a decisive role in ensuring structural stability. After the traditional rotary drilling rig constructs an opening hole and then drives a pile into the hole, it is necessary to replace the pile pressing equipment to continue the operation. Especially in the case of limited construction sites, the equipment replacement is extremely inconvenient, seriously affecting the construction efficiency and reducing the fluency of the operation. Therefore, Patent CN113027333B discloses a drilling and pile driving integrated rotary drilling rig and its construction method. By respectively arranging a drilling mechanism and a pile driving mechanism on the mounting frame, the drilling mechanism can drill holes in the ground, and then the pile driving mechanism on the mounting frame is used to pick up and drive the pile, without replacing accessories for the main body of the rotary drilling rig, improving the construction efficiency and being more convenient to use.

[0003] Meanwhile, during the drilling process, the drilling pressure will cause the soil in the drill bit to be compacted, resulting in the problem of difficult cleaning of the soil in the drill bit. To solve this problem, some existing technologies have been improved. For example, Patent CN201363086Y discloses a rotary drill for a rotary drilling rig. The drill bit is provided with a push plate that can move elastically. During drilling, as the soil in the inner cavity continuously increases, the push plate moves upward under pressure. When drilling stops, the push plate presses down to push out the soil. For example, Patent CN116591597B discloses a rotary drilling rig for highway bridge construction. When the sensor detects that the soil in the accommodating cavity has reached the state that needs to be discharged, the piston of the hydraulic cylinder of the control power mechanism extends outwards. When the piston extends, it pushes the muck door to rotate, opening the discharge port, and the soil is discharged from the discharge port under the guidance of the retaining ring.

[0004] As recorded in Patent CN113027333B, when combining the drilling device and the pile driving device to improve construction efficiency and convenience, it is difficult to set up a structure for cleaning soil in the drilling device, or it is necessary to separately set up a power mechanism for driving cleaning, which undoubtedly increases the complexity of the driving structure, raises the cost of the equipment and the difficulty of maintenance.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] See also Figures 1 to 4The composite pile foundation construction device 10 for a dock in one embodiment of the present application can at least improve the efficiency of piling. The composite pile foundation construction device 10 includes a piling mechanism 100 and an excavation mechanism 200. The piling mechanism 100 includes a base 110 and a hammer assembly 120. A movable cavity 111 is formed in the base 110. The hammer assembly 120 is movably disposed in the movable cavity 111. The excavation mechanism 200 includes a rotary drilling assembly 210, a connecting seat 220, a rotary drilling drive 230 and a cleaning assembly 240. The connecting seat 220 is detachably connected to the bottom of the base 110. The rotary drilling assembly 210 includes a rotary drilling barrel 211 and a rotary drilling head 212. The rotary drilling barrel 211 is rotatably arranged on the connecting seat 220. A slag cavity 213 is formed in the rotary drilling barrel 211, and a slag discharge port is formed on the side facing away from the connecting seat 220. The rotary drilling head 212 can be opened and closed to cover the slag discharge port. The rotary drilling drive 230 is used to drive the rotary drilling assembly 210 to rotate. The cleaning assembly 240 includes an agitator 241 and a first transmission member 242. The agitator 241 is rotatably disposed in the soil cavity 213. One end of the first transmission member 242 is connected to the agitator 241, and the other end passes through the connecting seat 220 to be transmission-connected to the hammer assembly 120. The hammer assembly 120 is used to drive the first transmission member 242 to move to drive the agitator 241 to rotate.

[0032] During construction, the digging mechanism 200 is started, and the digging mechanism 200 is first used to rotary dig the guide hole, and the rotary digging assembly 210 is driven to rotate by controlling the rotary digging driving member 230, so as to perform rotary digging of the guide hole. In this process, the soil that is rotary dug enters the slag cavity 213 of the rotary digging barrel 211. In view of the effect of the rotary pressure during the rotary digging process, the soil in the slag cavity 213 is easily compacted. At this time, the hammer assembly 120 in the base 110 is used to drive its movement. The hammer assembly 120 efficiently transmits power to the stirring member 241 set in the slag cavity 213 through the first transmission member 242. The stirring member 241 stirs the compacted soil, effectively destroying the compact structure of the soil, so that the soil can be smoothly discharged through the openable rotary digging head 212, greatly improving the soil discharge effect.

[0033] During pile driving, the excavation mechanism 200 is removed from below the base 110. Subsequently, one end of the pile foundation is inserted into the pre-dug guiding hole, and the other end is inserted into the moving cavity 111 of the base 110. At this time, the hammering assembly 120 is activated again. The hammering assembly 120 reciprocates within the moving cavity 111 to hammer the pile foundation, driving the pile foundation below the ground. The above-mentioned pile foundation composite construction device 10 only requires one piece of equipment to smoothly perform two key processes of drilling, soil discharging, and pile driving. During the process of discharging the soil after drilling, by means of the hammering assembly 120 driving the first transmission member 242, the stirring member 241 is driven to stir within the muck cavity 213, significantly improving the discharging efficiency of the soil within the muck cavity 213, greatly shortening the time required for drilling, and providing an efficient and reliable solution for the pile foundation construction of the wharf. The driving of the stirring member 241 does not require a separate power driving mechanism, but is realized by the movement of the hammering assembly 120 of the pile driving mechanism 100, avoiding the increase in structural complexity due to the addition of a power driving mechanism and the increase in equipment maintenance costs.

[0034] In one embodiment, the pile foundation composite construction device 10 further includes a frame 300 and a moving mechanism 400. The base 110 is slidably disposed on the frame 300. The moving mechanism 400 is disposed on the frame 300 and is used to drive the base 110 to move up and down. The hammering assembly 120 includes a hammer head 121 and a hammering driving member 122. The hammering driving member 122 is disposed on the base 110. The hammer head 121 is movably disposed within the moving cavity 111. The hammering driving member 122 is used to drive the hammer head 121 to reciprocate within the moving cavity 111. By means of the moving mechanism 400, it is convenient to adjust the position of the base 110. Furthermore, according to the pile driving depth, the position of the base 110 can be continuously adjusted to ensure the force exerted by the hammer head 121 on the pile each time. In this embodiment, the moving mechanism 400 can be a winch, and the winch is used to drive the position of the base 110. In other embodiments, the moving mechanism 400 can also be other mechanisms capable of driving the base 110 to move up and down.

[0035] In this embodiment, the hammering driving member 122 is a hydraulic driving member, and a hydraulic driving mechanism is used to drive the hammer head 121. In other embodiments, the hammering driving member 122 can also be an electric driving member, as long as it can realize the up and down movement of the hammer head 121 and can hammer the pile foundation.

[0036] Refer to Figure 2 and Figure 3, In one embodiment, the pile driving mechanism 100 further includes a clamping assembly 130. The clamping assembly 130 is disposed on the base 110 and is used to clamp the pile foundation disposed in the moving cavity 111, and the clamping assembly 130 can move up and down relative to the base 110. When the pile foundation is inserted into the moving cavity 111, the clamping assembly 130 is used to clamp the pile foundation to maintain the reliability of the pile foundation disposed in the moving cavity 111. And during the hammering process, the clamping assembly 130 clamps the pile foundation and moves together in the moving cavity 111, which can also play a stable guiding role in the process of driving the pile foundation into the ground. At the same time, when installing the pile foundation into the bored guiding hole, the clamping assembly 130 can be used to clamp the pile foundation, then move it above the guiding hole and put it into the guiding hole, which is convenient for the installation and positioning of the pile foundation.

[0037] Specifically, the clamping assembly 130 includes a clamping seat 131, a clamping driving member (not shown in the figure), at least two clamping jaws 132 and at least two clamping reset members 133. The clamping seat 131 is movably disposed on the base 110. A clamping space is formed inside the clamping seat 131. At least two clamping grooves 134 are formed on the inner wall of the clamping seat 131. Each clamping jaw 132 is disposed in a clamping groove 134 through a clamping reset member 133. The clamping reset member 133 is used to provide a reset force for the clamping jaw 132 to move away from the clamping space, and the clamping driving member is used to provide a thrust for the clamping jaw 132 to move towards the clamping space. In use, the clamping driving member can drive each clamping jaw 132 to overcome the elastic force of the clamping reset member 133 and move towards the clamping space, so as to clamp the pile foundation located in the clamping space; when clamping is not required, the clamping driving member releases the driving of the clamping jaw 132, and under the action of the clamping reset member 133, the clamping jaw 132 resets and moves away from the clamping space, thereby releasing the clamping of the pile foundation.

[0038] In this embodiment, an annular flow channel 135 is formed inside the clamping seat 131. One end of each clamping groove 134 away from the clamping space is communicated with the annular flow channel 135, and the clamping driving member is used to input or output pressure liquid into the annular flow channel 135. By introducing pressure liquid into the annular flow channel 135, the pressure liquid is used to enable the clamping jaw 132 to overcome the elastic force of the clamping reset member 133 and clamp the object located in the clamping space. Since the annular flow channel 135 can communicate with each clamping groove 134, it can further realize the synchronous movement of each clamping jaw 132, improving the uniformity of clamping. Specifically, an oil delivery pipe for communicating with the annular flow channel 135 is disposed on the base 110, and the clamping driving member is disposed on the base 110 and is used to input pressure liquid or output pressure liquid into the annular flow channel 135 through the oil delivery pipe.

[0039] In one embodiment, a hydraulic chamber 136 is provided in the clamping seat 131, and the clamping groove 134 is connected to the annular flow channel 135 through the hydraulic chamber 136. The end of each clamping jaw 132 facing away from the clamping space is connected to a piston rod 137, and the end of the piston rod 137 facing away from the clamping jaw 132 is connected to a piston body 138. The piston body 138 is movably arranged in the hydraulic chamber 136, and the piston body 138 is in sealing contact with the inner wall of the hydraulic chamber 136. The clamping reset member 133 is sleeved on the piston rod 137 to provide the piston body 138 with elastic force in a direction away from the clamping space. The piston body 138 can improve the sealing of the pressure liquid and reduce the possibility of leakage of the pressure liquid. The piston rod 137 is provided to facilitate the connection between the piston body 138 and the clamping jaw 132, thereby realizing the linkage between the piston body 138 and the clamping jaw 132.

[0040] In other embodiments, the clamping assembly 130 may also be of other structural forms. For example, the clamping jaw 132 may be driven to move into the clamping space by utilizing only the elastic force of the clamping reset member 133. When clamping is required, the clamping jaw 132 may be used to clamp the pile foundation by overcoming the elastic force of the clamping reset member 133.

[0041] See also Figure 1 , Figures 4 to 6 In one embodiment, the connection base 220 is detachably connected to the base 110. Specifically, a lifting lug is provided on the connection base 220, and a detachable fastener such as a screw can be used to connect the connection base 220 to the base 110. In other embodiments, the connection base 220 can also be connected to the base 110 by snapping or other detachable connection methods.

[0042] In one embodiment, the rotary drilling drive 230 can drive the rotary drilling barrel 211 to drive the rotary drilling head 212 to rotate. Specifically, the rotary drilling drive 230 is connected to the rotary drilling barrel 211 through a gear transmission mechanism, and the rotary drilling barrel 211 is driven by the gear transmission mechanism. For example, in this embodiment, since the agitator 241 needs to be arranged on the connecting seat 220, the first transmission member 242 needs to pass through the connecting seat 220, and at least two gears are directly engaged with the rotary drilling barrel 211. The at least two gears are arranged at intervals around the rotation axis of the rotary drilling barrel 211, and the space between the gears provides an installation space for the installation of the first transmission member 242 and other components. In other embodiments, the rotary drilling drive 230 can also achieve the rotation drive of the rotary drilling barrel 211 in other ways.

[0043] See also Figure 2 , Figures 4 to 6In one embodiment, the cleaning assembly 240 also includes a first reset member 243, the agitating member 241 includes a column 2411, an extension portion 2412 and a plurality of agitating rods 2413, the plurality of agitating members 241 are arranged on the column 2411 at intervals along the length direction of the column 2411, the extension portion 2412 is arranged on the column 2411 and is arranged at intervals around the circumference of the column 2411 with the agitating members 241, and the column 2411 is rotatably arranged in the soil cavity 213 through the first reset member 243. The first transmission member 242 includes a transmission rod 2421 and a plurality of toggle protrusions 2422. The plurality of toggle protrusions 2422 are arranged on the transmission rod 2421 at intervals along the length direction of the transmission rod 2421. Under the elastic force of the first reset member 243, the extension portion 2412 is located between two adjacent toggle protrusions 2422. When the hammer assembly 120 drives the transmission rod 2421 to move up and down, the toggle protrusion 2422 pushes the extension portion 2412 to drive the column 2411 to rotate. Since the extension part 2412 is located between two adjacent toggle protrusions 2422, when the hammer assembly 120 drives the transmission rod 2421 to move up and down, the toggle protrusion 2422 can push the extension part 2412 out of the space between the two toggle protrusions 2422, and the column 2411 is rotatably arranged on the connecting seat 220 by the first reset member 243, and the toggle protrusion 2422 can push the extension part 2412 to drive the column 2411 to rotate, thereby driving the plurality of stirring rods 2413 to rotate in the slag cavity 213. When the pushing effect of the toggle protrusion 2422 disappears, the first reset member 243 drives the stirring member 241 to reset, so that the extension part 2412 is reset to between the two toggle protrusions 2422, and this is repeated to realize the swing of the stirring rod 2413 in the slag cavity 213.

[0044] Specifically, the upper and lower surfaces of the moving protrusion 2422 are inclined surfaces, so that the extending portion 2412 can be better pushed to rotate during the up and down movement.

[0045] In other embodiments, when the first transmission member 242 reciprocates up and down, the first transmission member 242 and the column 2411 may be connected via a spiral structure, so as to achieve the purpose of driving the column 2411 to drive the agitator 241 to rotate or swing.

[0046] In one embodiment, a protective shell 250 is further provided in the slag cavity 213, and the protective shell 250 is provided on the connecting seat 220. The first transmission member 242 is penetrated in the protective shell 250 and can move in the protective shell 250. The protective shell 250 can protect the first transmission member 242, and prevent the soil from affecting the reciprocating movement of the first transmission member 242, and also prevent the soil from affecting the stability of the first transmission member 242 during drilling.

[0047] In one embodiment, the piling mechanism 100 further includes a second transmission member 140 (egFigure 2 As shown in the figure, the second transmission member 140 is disposed within the base 110. A limiting member 123 is provided on the outer wall of the hammering assembly 120. A clamping member 141 that is in limiting cooperation with the limiting member 123 is provided at one end of the second transmission member 140, and the other end is detachably connected to the first transmission member 242. Since the connecting seat 220 and the base 110 need to be detachably connected, the second transmission member 140 can be disposed within the base 110, and the second transmission member 140 is detachably connected to the first transmission member 242, so as to facilitate the separation of the excavation mechanism 200 and the piling mechanism 100.

[0048] Specifically, an inner portion of the outer wall of the base 110 is provided with a cavity for the second transmission member 140 to move, so as to prevent the movement of the second transmission member 140 from affecting the operation of components such as the hammering assembly 120. The second transmission member 140 can be connected to the first transmission member 242 by means of clamping or by means of screw connection.

[0049] Refer to Figure 2 、 Figure 5 and Figure 7 In one embodiment, the excavation mechanism 200 further includes a linkage assembly 260. The rotary digging head 212 is movably covered on the slag discharge port through the linkage assembly 260, and the clamping assembly 130 can drive the linkage assembly 260 to drive the rotary digging head 212 to move away from the rotary digging cylinder 211. Specifically, an opening is provided on the rotary digging head 212, so that soil can enter the slag cavity 213 through the opening during the drilling process. When the drilling is completed and the soil in the slag cavity 213 needs to be discharged, the clamping assembly 130 drives the linkage assembly 260 to move, and then drives the rotary digging head 212 to move away from the rotary digging cylinder 211, so as to open the slag discharge port and facilitate the discharge of the soil.

[0050] Specifically, the linkage assembly 260 includes a linkage rod 261, a connecting elastic member 262, and a connecting member 263. The rotary digging head 212 is slidably connected to the rotary digging cylinder 211 through the connecting member 263, and the connecting elastic member 262 is used to provide an elastic force for the rotary digging head 212 towards the rotary digging cylinder 211. An abutting inclined surface 139 is formed on one side of the jaw 132 facing the connecting seat 220. The abutting inclined surface 139 slopes upward along the direction towards the clamping space. One end of the linkage rod 261 abuts on the rotary digging head 212, and the other end passes through the connecting seat 220 and abuts on the abutting inclined surface 139. When the jaw 132 moves towards the clamping space, by using the abutting relationship between the abutting inclined surface 139 and the linkage rod 261, the linkage rod 261 is enabled to push the rotary digging head 212 to move away from the rotary digging cylinder 211 against the elastic force of the connecting elastic member 262, thereby opening the slag discharge port. When the jaw 132 is reset, by using the elastic force of the connecting elastic member 262, the rotary digging head 212 is enabled to be reset towards the rotary digging cylinder 211 to cover the slag discharge port.

[0051] In this embodiment, a connection hole 214 is provided at the end of the side wall of the rotary drilling barrel 211 facing the rotary drilling head 212, and a connection member 263 is movably inserted into the connection hole 214 through a connection elastic member 262, and the connection member 263 can move up and down in the connection hole 214. Further, the number of the connection holes 214 is at least two, and each connection hole 214 is arranged at intervals around the axis of the rotary drilling barrel 211, and the number of the connection members 263 matches the number of the connection holes 214. By providing at least two connection members 263 to cooperate with the connection holes 214, the circumferential rotation of the rotary drilling head 212 and the rotary drilling barrel 211 can be limited, and the reliability of the connection and opening of the rotary drilling head 212 and the rotary drilling barrel 211 can be improved by at least two connection members 263.

[0052] In one embodiment, the linkage assembly 260 further includes a linkage reset member 264, which is used to provide elastic force for the linkage rod 261 in a direction away from the rotary digging head 212. Specifically, the linkage rod 261 is arranged on the connecting seat 220 through the linkage reset member 264. The linkage reset member 264 can provide elastic force for resetting the linkage rod 261, thereby preventing the linkage rod 261 from applying force to the rotary digging head 212 when the rotary digging head 212 is not opened, thereby affecting the reliability of the rotary digging head 212 covering the slag discharge port.

[0053] See also Figure 2 , Figure 5 and Figure 6 In one embodiment, a cavity is formed in the column 2411, and the linkage rod 261 is inserted into the cavity. By inserting the linkage rod 261 into the column 2411, installation space can be saved, and the soil in the slag cavity 213 can be prevented from affecting the movement of the linkage rod 261.

[0054] Specifically, the cleaning assembly 240 also includes a knocking elastic member 244 and a knocking portion 245. The knocking portion 245 is arranged on the connecting seat 220 through the knocking elastic member 244. The knocking elastic member 244 is used to provide the knocking portion 245 with an elastic force to move toward the linkage rod 261. The knocking portion 245 is located between two adjacent toggling protrusions 2422. The toggling protrusion 2422 can push the knocking portion 245 to move in a direction away from the linkage rod 261. When the first transmission member 242 moves up and down, the toggle protrusion 2422 synchronously pushes the knocking part 245 to move in the direction away from the linkage rod 261. When the toggle protrusion 2422 releases the push on the knocking part 245, under the action of the knocking elastic member 244, the knocking part 245 is reset and knocks on the linkage rod 261. The linkage rod 261 is penetrated by the column 2411 and connected to the rotary drill head 212, so that the knocking vibration can be transmitted to the agitator 241 and the rotary drill head 212, thereby further improving the soil discharge effect.

[0055] In this embodiment, the knocking portion 245 is a U-shaped rod, the linkage rod 261 is located in the bending space of the U-shaped rod, and the two ends of the knocking portion 245 can be located between two adjacent toggle protrusions 2422. In other embodiments, the knocking portion 245 can also be a component of other shapes, as long as it can knock the linkage rod 261 to achieve vibration transmission. In other embodiments, the knocking portion 245 can also be omitted.

[0056] In the above-mentioned pile foundation composite construction device 10 for docks, the digging mechanism 200 is started during the drilling operation stage. By controlling the rotary drilling drive 230, the rotary drilling assembly 210 is driven to rotate at a high speed to perform rotary drilling of the guide hole. In this process, the soil cut by the rotary drilling enters the slag cavity 213 of the rotary drilling barrel 211. Due to the continuous action of the strong rotary pressure during the rotary drilling process, the soil in the slag cavity 213 is easily compacted into a tight state.

[0057] Entering the soil discharge stage, the hammer assembly 120 drives the transmission rod 2421 to reciprocate up and down. Since the extension 2412 of the stirring member 241 is located between two adjacent toggling protrusions 2422, the toggling protrusion 2422 can push the extension 2412 out of the space where it is located; when the thrust of the toggling protrusion 2422 disappears, the first reset member 243 plays a role, driving the stirring member 241 to reset, and then driving the column 2411 and the stirring rod 2413 to swing in the slag cavity 213, effectively destroying the compact structure of the soil. Then, the driving jaw 132 moves toward the clamping space direction, and by utilizing the abutment relationship between the abutment slope 139 and the linkage rod 261, the linkage rod 261 pushes the rotary digging head 212 to overcome the elastic force of the connecting elastic member 262 and move in the direction away from the rotary digging barrel 211, thereby smoothly opening the slag discharge port and allowing the loose soil to be discharged. When the clamping jaws 132 are reset, the elastic force of the connecting elastic member 262 causes the rotary drilling head 212 to reset toward the rotary drilling barrel 211, covering the slag discharge port again, thereby improving the effect of soil discharge.

[0058] During the piling stage, the excavation mechanism 200 is removed from under the base 110. Then, the clamping assembly 130 is used to firmly clamp the pile foundation to ensure that the pile foundation is firmly set in the moving cavity 111, and the other end of the pile foundation is inserted into the pre-dug guide hole. At this moment, the hammer assembly 120 is started again, and the hammer assembly 120 moves back and forth in the moving cavity 111 to hammer the pile foundation and drive the pile foundation into the ground. During the construction process, the position of the base 110 can be continuously adjusted through the moving mechanism 400 according to the requirements of the piling depth, so as to ensure that the force of the hammer head 121 when hammering the pile foundation is accurate and stable each time.

[0059] In summary, the pile foundation composite construction device 10 only requires one piece of equipment to smoothly and efficiently complete several key processes such as drilling, soil removal, and pile driving, greatly improving the construction efficiency and quality, and providing a very reliable solution for the pile foundation construction of the wharf.
