Description

Technical Field

[0001] This invention relates to the field of wharf construction equipment technology, and in particular to a construction equipment for wharf construction. Background Technology

[0002] Wharf construction is a crucial part of port engineering construction. Its quality directly affects the wharf's load-bearing capacity, service life, and operational safety. Conventional wharf construction mainly includes steps such as site leveling, foundation treatment, pile foundation construction, superstructure pouring, and installation of ancillary facilities. Among these, pile foundation, as the core support system of the wharf structure, plays a decisive role in the overall stability of the project.

[0003] In bored pile construction, existing technologies typically use rotary drilling rigs, impact drilling rigs, or rotary drilling rigs to form holes, followed by the installation of steel cages and the pouring of concrete to form the pile body.

[0004] However, in actual wharf construction, especially under complex hydrogeological conditions, conventional drilling equipment often faces problems such as low drilling efficiency and easy collapse of the borehole wall. In addition, the wharf construction area is often close to water, and is affected by tides, waves and underwater visibility, which further increases the difficulty of borehole positioning and construction accuracy control.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0034] Reference Figures 1 to 6 This is the first embodiment of the present invention. This embodiment provides a construction equipment for wharf construction, which can complete drilling while also causing the moving ring 25 to perform reciprocating swing motion.

[0035] Specifically, a construction equipment for wharf construction includes a drilling assembly 1, comprising a drilling machine 11, a hole drill 14 disposed outside the drilling machine 11, and a movable column 13 mounted on the upper end face of the hole drill 14; wherein, the drilling machine 11 is designed for high-hanging, and uses a drive source such as a motor to drive the hole drill 14 through a drive shaft 12 to complete the pile foundation drilling action, the movable column 13 is in a fixed state, the hole drill 14 is generally inverted conical in shape, and can rotate along the lower end face of the movable column 13, and the diameter of the movable column 13 is slightly smaller than the maximum diameter of the hole drill 14.

[0036] The compaction component 2 includes a moving ring 25 disposed inside the moving column 13, guide rods 28 disposed on both sides of the outer wall of the moving ring 25, and a compaction block 210 movably connected to the end face of the guide rod 28. The compaction component 2 is designed with multiple layers and multiple groups, with each layer staggered to ensure that the compaction blocks 210 at different positions can compact the inner wall of the pile foundation around the perimeter, reducing voids. The compaction block 210 is a strip-shaped design with a certain weight to ensure the compaction effect. The side of the moving ring 25 near the drive shaft 12 has an outwardly convex conical design. Guide rods 28 are provided on both sides of the outer wall of each moving ring 25. It should be noted that the guide rods 28 on both sides move alternately back and forth following the swinging motion of the moving ring 25. The maximum travel of the guide rods 28 needs to ensure that the outer wall of the compaction block 210 contacts the inner wall of the pile foundation and achieves an impact compaction effect.

[0037] The spraying assembly 3 includes a fixed seat 31 located inside the movable column 13 and an injection tube 32 fixedly installed on the outer wall of the fixed seat 31. The spraying assembly 3 is only located on the uppermost movable ring 25. The fixed seat 31 is in a fixed state and serves as a support. Each fixed seat 31 has two sets of injection tubes 32 on its outer wall, corresponding to the guide rods 28 and the compaction block 210 on both sides. The interface enhancement coating is sprayed onto the inner wall of the pile foundation using the injection tubes 32. It should be noted that since the spraying assembly 3 is only located in the compaction assembly 2 on the uppermost side, the upper surface of the uppermost movable ring 25 is designed to be concave to avoid interference with the injection tubes 32 and improve the utilization rate of the movable column 13's capacity.

[0038] The drilling machine 11 drives the drill 14 to rotate to complete the drilling and piling operation. At the same time, the rotation of the drill 14 provides power to the moving ring 25, which drives the compaction blocks 210 on both sides to perform alternating reciprocating motion to compact the inner wall of the borehole and prevent collapse. Meanwhile, the injection of interface-enhancing coating in the injection tube 32 further improves the compaction effect of the inner wall of the borehole.

[0039] Furthermore, the drilling assembly 1 also includes a drive shaft 12 mounted on the outer wall of the drilling machine 11. The drive shaft 12 passes through the movable column 13 and its end is fixedly connected to the upper end face of the hole drill 14. The drive shaft 12 passes through the movable column 13 and its bottom is fixedly connected to the hole drill 14, so that the hole drill 14 can be rotated by a drive source installed in the drilling machine 11.

[0040] It should be noted that the tamping component 2 also includes a first bevel gear 21 fixedly connected to the outer wall of the drive shaft 12, a first connecting shaft 23 rotatably connected inside the moving column 13, a second bevel gear 22 fixedly connected to one end of the first connecting shaft 23, the second bevel gear 22 meshing with the first bevel gear 21, and a transmission block 24 fixedly connected to the other end of the first connecting shaft 23. The first bevel gear 21 is designed in multiple sets, equidistantly arranged along the drive shaft 12, and multiple sets of second bevel gears 22 are arranged on the outer wall of the same first bevel gear 21. The meshing connection between the second bevel gear 22 and the first bevel gear 21 converts the rotational motion of the drive shaft 12 into the rotation of the first connecting shaft 23. The end of the transmission block 24 is designed with an inclination, thereby using the bent design of the transmission block 24 to convert the rotational motion of the first connecting shaft 23 into the circular motion of the transmission block 24.

[0041] Preferably, a mounting bracket 212 is fixedly connected to the inner wall of the movable column 13, and a first connecting ball 26 is movably connected to the inner side of the mounting bracket 212. A second connecting shaft 27 is rotatably connected to the outer wall of the transmission block 24. The second connecting shaft 27 passes through the movable ring 25 and its end is located on the end face of the first connecting ball 26. The mounting bracket 212 connects to the first connecting ball 26 to ensure that the first connecting ball 26 remains in a movable state. The two ends of the second connecting shaft 27 are respectively connected to the transmission block 24 and the first connecting ball 26. Simultaneously, the second connecting shaft 27 is also fixedly connected to the movable ring 25, thereby driving the movable ring 25 to perform a continuous oscillating motion.

[0042] In operation, the drilling machine 11 drives the drill 14 to rotate via the drive shaft 12. As the drive shaft 12 descends, the drill 14 completes the pile drilling operation in the soil. As the drilling continues, the moving column 13 moves into the pile foundation drilled by the drill 14. When the drive shaft 12 rotates, its outer wall's first bevel gear 21 rotates synchronously. The rotation of the first bevel gear 21 drives the second bevel gear 22 to rotate synchronously, thereby causing the transmission block 24 to move in a circular motion around the first connecting shaft 23. Because the transmission block 24 has a bent design, from... The transmission block 24 drives the moving ring 25 to move via the second connecting shaft 27. Since the side connected to the moving ring 25 is the inclined surface of the transmission block 24, the moving ring 25 follows the inclined surface of the transmission block 24 to make a reciprocating swinging motion. Since the end of the second connecting shaft 27 is fixedly connected to the first connecting ball 26, when the second connecting shaft 27 follows the transmission block 24 to start moving, the first connecting ball 26 is adaptively in an active state inside the mounting bracket 212, and the first connecting ball 26 provides support and guidance for the moving ring 25.

[0043] In summary, the drilling assembly 1 completes the piling drilling action. As drilling progresses, the rotation of the drive shaft 12 drives the first bevel gear 21 at different positions to start rotating, thereby providing sufficient power input to the compaction assembly 2. The design of the first connecting shaft 23, the second connecting shaft 27 and the transmission block 24 converts the rotation of the drive shaft 12 into the swinging motion of the moving ring 25, thereby providing power for the alternating compaction of the compaction blocks 210 on both sides. Example 2

[0044] Reference Figures 2-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a structure that ensures that the compaction blocks 210 on both sides can stably complete the alternating reciprocating motion.

[0045] Specifically, both ends of the guide rod 28 are fixedly connected to second connecting balls 29. One set of second connecting balls 29 is located inside the compaction block 210, and the other set is movably connected to the outer wall of the moving ring 25. The guide rod 28 has second connecting balls 29 on both sides. One set of second connecting balls 29 is fixedly connected to the compaction block 210 for guiding and positioning, while the other set is movably connected to the outer wall of the moving ring 25. Since the moving ring 25 undergoes a swaying motion during this process, the movably designed second connecting balls 29 on this side ensure that the guide rod 28 can also adapt to the movement trajectory of the moving ring 25, driving the compaction block 210 to move stably in a straight line.

[0046] Furthermore, a guide block 211 is fixedly connected to the outer wall of the moving ring 25, and a positioning groove 214 and a swing cavity 213 for the moving ring 25 to move are formed on the outer wall of the moving column 13. The first connecting shaft 23 is connected to the moving column 13 through the positioning groove 214, and the swing cavity 213 and the positioning groove 214 are connected. Among them, there are two sets of guide blocks 211 on each moving ring 25, located on both sides of the end face of the moving ring 25 respectively. The swing cavity 213 is a spherical groove to ensure that the moving ring 25 can move in the swing cavity 213. The positioning groove 214 is composed of a straight groove and a cylindrical groove. The second bevel gear 22 and the first connecting shaft 23 can rotate in the positioning groove 214. The positioning groove 214 limits the first connecting shaft 23 to ensure its stable rotation.

[0047] Preferably, the outer wall of the movable column 13 is also provided with a first guide groove 215 and a second guide groove 216. The guide block 211 can slide along the first guide groove 215, and the second guide groove 216 penetrates the movable column 13, and the compaction block 210 can slide along the second guide groove 216. The first guide groove 215 is designed along the swing cavity 213 and is circular in shape to accommodate the movement of the guide block 211. The contact between the first guide groove 215 and the guide block 211 ensures the stability of the swing motion of the movable ring 25. At the same time, the second guide groove 216 is designed in two sets on this side of the swing cavity 213 to ensure that the compaction block 210 can move linearly along the second guide groove 216, achieving the compaction and contraction effect. Furthermore, the second guide groove 216 not only undertakes the task of moving the compaction block 210, but also further guides the movement of the compaction block 210 in the compaction assembly 2.

[0048] The rest of the structure is the same as in Example 1.

[0049] In use, when the moving ring 25 is driven by the drilling assembly 1 to perform alternating oscillating motion, the second bevel gear 22 and the first connecting shaft 23 rotate within the positioning groove 214, and the moving ring 25 completes the oscillating motion within the oscillation cavity 213. At the same time, the guide blocks 211 fixedly connected to both sides of the outer wall of the moving ring 25 slide along the first guide groove 215 to ensure the stable oscillation motion of the moving ring 25. At this time, the guide rod 28 uses the second connecting ball 29 fixed within the compaction block 210 as its axis, and the second connecting ball 29 movably connected to the outer wall of the moving ring 25 follows the moving ring 25 to perform adaptive motion. This causes the guide rods 28 on both sides to follow the moving ring 25 to perform alternating linear motion along the second guide groove 216, thereby driving the compaction blocks 210 on both sides to perform alternating linear motion synchronously. The reciprocating motion of the compaction blocks 210 achieves a synchronous compaction effect on the inner wall of the drilled pile foundation.

[0050] In summary, the swinging motion of the moving ring 25 drives the tamping blocks 210 on both sides to make alternating linear motion, thereby tamping the inner wall of the pile foundation. This achieves simultaneous drilling and tamping, reducing the risk of pile foundation collapse and avoiding manual operation. Furthermore, the design of multiple guide grooves ensures that each component in the tamping assembly 2 has sufficient space to move while also providing a guiding and limiting effect, further ensuring the completion of the tamping action. Example 3

[0051] Reference Figure 6 and Figure 7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a structure that can simultaneously achieve the spraying and injection of reinforcing coatings while drilling and compaction of the inner wall of the pile foundation are being carried out.

[0052] Specifically, the spraying assembly 3 also includes a movable frame 34 installed inside the movable column 13. A connecting rod 37 is fixedly connected to the center of the outer wall of the movable frame 34, and the end face of the connecting rod 37 is rotatably connected to the inner wall of the movable column 13. Two sets of movable frames 34 are provided on the outer side of each movable ring 25. The movable frame 34 has a bent design and rotates around the connecting rod 37. Accordingly, sufficient space needs to be provided in the inner wall of the movable column 13 for the movable frame 34 to move.

[0053] Furthermore, the lower end face of the movable frame 34 is at the same level as the compaction block 210, and a spring 35 is provided on the upper end face of the movable frame 34, with the end of the spring 35 located on the outer wall of the fixed base 31. The injection tube 32 is installed inside the fixed base 31, and the piston 36 is adapted to the internal channel of the injection tube 32. The lower surface of the movable frame 34 is at the same height as the compaction block 210. It should be noted that when one of the guide rods 28 retracts to a certain position, the second connecting ball 29 connected to the outer wall of the movable ring 25 on that side will contact the outer wall of the movable frame 34. When the guide rod 28 retracts to its limit position, causing the movable frame 34 to begin rotating, its upper surface will compress the spring 35, causing the piston 36 to move a certain distance, thus achieving injection.

[0054] Preferably, the outer wall of the movable frame 34 is provided with a piston 36, which can slide along the inside of the injection tube 32. The upper end face of the fixed seat 31 is provided with a storage tank 33, which is connected to the injection tube 32. There are two sets of storage tanks 33 on each fixed seat 31, and they are connected to the corresponding injection tubes 32. A certain amount of interface-enhancing coating is stored in the storage tank 33, and the movement of the piston 36 enables the quantitative injection of the interface-enhancing coating. It should be noted that a removable protective cover needs to be designed on the outer surface of the movable column 13 to facilitate the replenishment of coating in the storage tank 33. Furthermore, the coating should be replenished in the storage tank 33 after the spraying assembly 3 enters the pile foundation to avoid waste.

[0055] The rest of the structure is the same as in Example 2.

[0056] In use, when the moving ring 25 begins to swing, the guide rod 28 follows the moving ring 25 and moves linearly along the second guide groove 216. When one side of the guide rod 28 retracts to a certain position, the second connecting ball 29 on the side of its end face near the moving frame 34 begins to contact the lower end face of the moving frame 34, thereby driving the moving frame 34 to move around the connecting rod 37 as the axis. At this time, the bottom of the moving frame 34 on that side retracts, while the top moves towards the side near the storage tank 33. At this time, the storage tank 33 compresses the spring 35, driving the piston 36 along the injection tube 32. The inner wall slides, quantitatively injecting the interface-enhancing coating from the injection tube 32 onto the inner wall of the pile foundation. Since the drilling descent takes a certain amount of time, when the coating is injected into the inner wall of the pile foundation, the compaction component 2 works together to bring the coating into contact with the inner wall of the pile foundation, further ensuring the effect of coating contact with the geology. When the guide rod 28 moves forward, the moving frame 34 is reset by the elastic force of the spring 35, and the piston 36 quantitatively sucks out the coating from the storage tank 33, waiting for the next injection. The alternating movement of the guide rod 28 realizes the alternating injection of the interface-enhancing coating, further reducing settlement and increasing side friction resistance.

[0057] In summary, the reciprocating motion of the guide rod 28 inside the compaction component 2 drives the movement of the moving frame 34, thereby using the connecting rod 37 as the axis of rotation to realize the forward and backward movement of the piston 36, thus completing the quantitative injection and extraction of the coating. At the same time, it can also cooperate with the compaction component 2 to ensure the contact between the coating and the soil, further ensuring the stability of the pile foundation.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
