Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile driving technology in water conservancy construction, and in particular to a pile driving device for water conservancy construction. Background Technology
[0002] Water conservancy projects are engineering systems that regulate surface water and groundwater to achieve comprehensive utilization of water resources, encompassing multiple fields such as flood control, irrigation, water supply, power generation, navigation, and ecological restoration. Their core function is to optimize the spatial and temporal distribution of water resources, prevent floods and droughts, and ensure the water needs for production and daily life by constructing facilities such as dikes, canals, pumping stations, and reservoirs.
[0003] Piling machines for water conservancy projects are pile foundation operation equipment specifically designed for water conservancy engineering construction. They are mainly used in riverbank protection, embankment reinforcement, and wharf construction. Their core function is to drive piles into the ground through high-frequency vibration or impact, thereby enhancing structural stability.
[0004] In smaller projects where large pile drivers are often difficult to access, portable pile drivers are typically used. The working principle of a portable pile driver is based on hydraulic transmission and inertial impact technology. Its core is the conversion of hydraulic energy into mechanical energy to drive the hammer and generate high-frequency impact force. The main unit consists of a cylinder, piston, drill bit, and control valves. The hydraulic system drives the piston in a periodic reciprocating motion. When the hydraulic oil pressure above the piston increases, it pushes the hammer downwards to strike the drill bit, transferring mechanical energy to the pile and achieving pile driving. When the pressure decreases, the piston rises, completing one impact cycle. Some models use a hybrid hydraulic-pneumatic drive, using compressed air to enhance the impact force, while also incorporating a small gasoline engine to address external power limitations, achieving a balance between power and portability. Its separate design allows the power unit to be placed on the ground, reducing the weight of the operating components, and enabling two people to operate in confined spaces.
[0005] However, portable pile drivers have significant instability issues. Their lightweight design results in a lighter weight, which makes them prone to displacement or vibration due to reaction forces when operating in hard strata or strong winds, affecting the verticality of the pile driving and requiring frequent manual correction. Utility Model Content
[0006] Therefore, it is necessary to address the problem that lightweight design results in a lighter equipment weight, which makes it prone to displacement or vibration due to reaction forces when operating in hard strata or strong wind environments, affecting the verticality of pile driving and requiring frequent manual correction. This issue requires a new type of pile driving equipment for hydraulic construction.
[0007] A pile driving device for water conservancy construction includes: a pile driver body, guide frames fixedly connected to both sides of the pile driver body, a bracket slidably attached to the side of the two guide frames that are far apart from each other, a limit frame movably connected to the side of the two brackets that are close to each other, and a vertical pile movably inserted into the inside of the limit frame, the vertical pile standing vertically below the pile driver body.
[0008] The auxiliary frame is provided in four parts, which are located on both sides of the two auxiliary frames respectively. Each of the auxiliary frames has a support component movably provided below the side of the support frame that is close to the bracket, and each of the support components has a limiting component above it.
[0009] In one embodiment, a support plate is fixedly connected to the bottom of each of the two supports and the four auxiliary frames, and the diameter of each of the support plates is larger than the bottom area of the two supports and the four auxiliary frames.
[0010] In one embodiment, sliders are fixedly connected to both sides of the limiting frame, and slide rails are provided inside the two brackets. The two guide frames and the two sliders slide inside the slide rails of the two limiting frames respectively.
[0011] In one embodiment, a limit lock is movably connected to one side of the limiting frame, and the side of the limit lock and the limiting frame that are close to each other is in contact with the outer wall of the post.
[0012] In one embodiment, the support assembly includes support blocks that are fixedly connected to the bracket and the auxiliary frame respectively, and a support frame is movably connected between the two support blocks. The length of the support frame is changed by threads to change the distance between the bracket and the auxiliary frame.
[0013] In one embodiment, a pivot is movably connected to the middle of the support frame, and the pivot and the support frame sleeve rotate coaxially.
[0014] In one embodiment, the limiting component includes a telescopic rod fixed to one of the support blocks, one end of the telescopic rod being fixedly connected to a limiting block, and one side of the limiting block being engaged with the outer wall of the rotating shaft.
[0015] In one embodiment, a lever is fixedly connected to one side of the limiting block, and anti-slip texture is provided on the upper side of one side of the lever. Beneficial effects
[0016] 1. This piling equipment generates high-frequency vibration through the hydraulic vibratory hammer of the piling machine body, which is transmitted to the bottom of the pile via an intelligent control system. Soil resonance is used to reduce penetration resistance. The linear guide rails of the guide frame and support, in conjunction with the double-row sliders of the limit frame, ensure the verticality of the pile. The auxiliary frame and support components form a stable structure. The threaded adjustment of the support frame compensates for foundation settlement. The limit components form an anti-torsional lock through spline engagement, absorbing horizontal impacts. The V-shaped teeth and corrugated pads of the limit lock prevent axial displacement. The support plate disperses ground pressure. The self-lubricating properties of the nylon sliders are suitable for soft soil foundation operations, improving the equipment's ability to maintain continuous operation even in soft soil conditions.
[0017] 2. The rotating shaft adopts a high-precision bearing support structure, with its axis completely aligned with the axis of the support frame sleeve. The rotating shaft surface is machined with straight-tooth splines, forming a backlash-free transmission pair with the toothed meshing surface of the limiting block, preventing angular deviation caused by vibration. The telescopic rod is spring-driven, with an adjustable stroke range covering the full length variation of the support frame. The limiting block adopts a segmented rack and pinion structure, automatically aligning when meshing with the rotating shaft splines, eliminating transmission backlash. When the pile driver body encounters a horizontal impact load, the limiting block absorbs energy through tooth surface friction damping, preventing accidental rotation of the support frame. The lever is made of high-strength engineering plastic, with a diamond-shaped convex dot array design on the surface anti-slip texture, conforming to ergonomic grip requirements. Operators can manually release the engagement state between the limiting block and the rotating shaft through the lever, achieving quick unlocking and locking of the support frame.

[0030] The following is combined Figures 1-4 This utility model describes a pile driving device for water conservancy construction.
[0031] In one embodiment, a pile driving device for hydraulic construction includes: a pile driver body 200 and an auxiliary frame 101. Guide frames 201 are fixedly connected to both sides of the pile driver body 200. A support 100 is slidably attached to the side of the two guide frames 201 that is far apart from each other. A limiting frame 400 is movably connected to the side of the two support frames 100 that is close to each other. A vertical pile 500 is movably inserted into the inside of the limiting frame 400. The vertical pile 500 is vertically below the pile driver body 200. Four auxiliary frames 101 are provided. The four auxiliary frames 101 are respectively located on both sides of the two auxiliary frames 101. A support component 300 is movably provided below the side of the multiple auxiliary frames 101 that is close to the support 100. A limiting component 600 is provided above the multiple support components 300.
[0032] In this embodiment, the pile driver body 200, as the core actuator, integrates a hydraulic vibratory hammer and an intelligent control system. It achieves pile penetration through high-frequency vibration. The pile driver body 200 has detachable guide frames 201 installed on both sides. The guide frames are made of high-strength aluminum alloy and have been hard anodized. The guide frames 201 and the support 100 are slidably connected by linear guide rails to ensure a small verticality error. The limit frame 400 is located inside the support 100 and slides and is sleeved on the surface of the pile 500. The height of the limit frame 400 can be adjusted. The limit frame 400 moves up and down with the top or bottom of the pile 500. Multiple limit frames 400 can also be installed as needed to improve the stability of the pile 500 when it descends.
[0033] The auxiliary frame 101 adopts a triangular truss structure and is distributed on the front and rear sides of the support 100. Two sets of auxiliary frames 101 on each side form a self-stabilizing system through the support component 300. The support component 300 includes threaded columns. By adjusting the length of the support component 300, it can accommodate the installation on different bottom inclined surfaces. The limiting component 600 consists of a spring push rod and an arc-shaped clamp. The clamp is lined with a high-friction coefficient rubber pad to prevent the support component 300 from twisting during piling and to improve the stability of the piling machine body 200 in the cooperation between the support 100 and the auxiliary frame 101 during piling.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, support plates 102 are fixedly connected to the bottom of the two supports 100 and the four auxiliary frames 101. The diameter of the multiple support plates 102 is larger than the bottom area of the two supports 100 and the four auxiliary frames 101. Slider blocks 401 are fixedly connected to both sides of the limiting frame 400. Slide rails are opened inside the two supports 100. The two guide frames 201 and the two sliders 401 slide inside the slide rails of the two limiting frames 400 respectively.
[0035] In this embodiment, the support plate 102 welded to the bottom of the two supports 100 and the four auxiliary frames 101 adopts a trapezoidal structure design. Its diameter is larger than that of the support 100 and the auxiliary frame 101 body, forming a stable base platform, which can effectively disperse the vertical impact load generated during pile driving and reduce the settlement and displacement of the equipment in soft soil foundation or sloping conditions.
[0036] The sliders 401 welded on both sides of the limit frame 400 adopt a double-row layout. The sliders 401 and the slide rails opened on the inner wall of the bracket 100 form a precision guide pair. The slider 401 body is made of high-strength nylon material, with embedded bronze alloy guide strips. The surface is machined with oil storage grooves and microporous structures to achieve continuous lubrication through capillary action, effectively reducing the coefficient of friction. The torsional stiffness of the limit frame 400 during vertical lifting is increased. When the pile 500 is inserted, the limit frame 400 ensures dynamic correction of the pile verticality through the synergistic action of the sliders 401 and the slide rails.
[0037] like Figure 2 , Figure 3 and Figure 4 As shown, a limit lock 402 is movably connected to one side of the limit frame 400. The side of the limit lock 402 and the limit frame 400 that are close to each other are in contact with the outer wall of the post 500. The support assembly 300 includes support blocks 301 that are fixedly connected to the bracket 100 and the auxiliary frame 101 respectively. A support frame 302 is movably connected between the two support blocks 301. The length of the support frame 302 is changed by threads to change the distance between the bracket 100 and the auxiliary frame 101.
[0038] In this embodiment, the limit lock 402 adopts a split wedge locking structure, which can be quickly clamped by a manual knob. The pin is detachable, which makes it easy to adjust the position of the limit lock 402. Its locking surface is machined with V-shaped teeth. The limit lock 402 and the wave-shaped pad on the inner wall of the limit frame 400 form a multi-point engagement, which effectively prevents the post 500 from axial movement or circumferential torsion under high-frequency vibration.
[0039] Both support blocks 301 are connected to the bracket 100 and auxiliary frame 101 using ball joint bearings, allowing ±5° angular sway to adapt to complex terrain. The main body of the support frame 302 is a high-strength alloy steel threaded sleeve with an embedded thread for quick adjustment. A single rotation can shorten or lengthen the sleeve. The thread surface is nitrided and copper-based graphite grease is used to ensure smooth adjustment and maintain a constant distance between the bracket 100 and the auxiliary frame 101.
[0040] like Figure 2 , Figure 3 and Figure 4 As shown, a rotating shaft 303 is movably connected to the middle of the support frame 302. The rotating shaft 303 and the sleeve of the support frame 302 rotate coaxially. The limiting component 600 includes a telescopic rod 601 fixed on one of the support blocks 301. One end of the telescopic rod 601 is fixedly connected to a limiting block 602. One side of the limiting block 602 is engaged with the outer wall of the rotating shaft 303. A lever plate 603 is fixedly connected to one side of the limiting block 602. Anti-slip texture is provided on the upper side of one side of the lever plate 603.
[0041] In this embodiment, the rotating shaft 303 adopts a high-precision bearing support structure, and its axis is completely coincident with the sleeve axis of the support frame 302. The surface of the rotating shaft 303 is machined with straight tooth splines, which form a backlash-free transmission pair with the toothed meshing surface of the limiting block 602 to prevent angular deviation caused by vibration. The telescopic rod 601 is spring driven, and the adjustable stroke range covers the full length change of the support frame 302. The limiting block 602 adopts a segmented rack and pinion structure, which automatically centers when meshing with the spline of the rotating shaft 303 to eliminate transmission backlash. When the pile driver body 200 encounters a horizontal impact load, the limiting block 602 absorbs energy through tooth surface friction damping to prevent the support frame 302 from rotating accidentally. The lever 603 is made of high-strength engineering plastic material, and the surface anti-slip texture adopts a diamond-shaped convex dot array design, which meets the ergonomic grip requirements. The operator can manually release the meshing state of the limiting block 602 and the rotating shaft 303 through the lever 603 to realize the quick unlocking and locking of the support frame 302.
[0042] Working principle:
[0043] The pile driver body 200 serves as the core power source. Its built-in hydraulic vibratory hammer generates high-frequency vibration energy, which is modulated by the intelligent control system and transmitted to the bottom of the pile 500. The penetration resistance is reduced through the soil resonance effect. When the pile driver body 200 is in operation, the guide frame 201 and the linear guide rail of the support 100 form a vertical guiding system. The double-row slider 401 of the limit frame 400 slides precisely within the slide rail of the support 100 to control the verticality error of the pile 500.
[0044] The auxiliary frame 101 and the support 100 form a spatially stable structure through the support component 300: the threaded adjustment mechanism of the support frame 302 can compensate for the foundation settlement in real time, the support block 301 connected by the ball joint bearing allows ±5° terrain adaptive sway, the telescopic rod 601 of the limiting component 600 drives the limiting block 602 to engage with the rotating shaft 303 spline to form an anti-torsion locking mechanism. When encountering horizontal impact, the tooth surface friction damping can absorb the impact energy.
[0045] The V-shaped teeth of the limit lock 402 and the wave-shaped pad of the limit frame 400 form a double clamping system to prevent the pile 500 from axial displacement under high-frequency vibration. The base design of the support plate 102 disperses the grounding pressure. Combined with the self-lubricating properties of the high-strength nylon slider 401, it ensures that the equipment can maintain continuous operation under soft soil foundation conditions.
[0046] It should be noted that the piling machine body 200 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the piling machine body 200 can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
