Description

Technical Field

[0001] This utility model relates to the field of marine pile driving technology, and in particular to a marine pile driving device. Background Technology

[0002] Offshore pile driving typically refers to sinking prefabricated piles (such as steel piles, reinforced concrete piles, prestressed reinforced concrete piles, etc.) into the seabed using specialized equipment to form a stable foundation. This method is suitable for deep sea areas or thick soil layers, effectively reducing the difficulty and cost of foundation construction. It is widely used in projects such as cross-sea bridges, offshore wind farms, and offshore oil and gas platforms. The typical device uses a hoisting rope to move the pile hammer up and down for driving. During the movement, the pile hammer is prone to shaking, causing the hammering force to deviate when the pile hammer contacts the pile driver, thus affecting the pile driving effect of the device.

[0003] The prior art CN221276594U discloses a pile driver for assisting offshore pile driving construction, including a steel pipe pile, a pile driver, a clamping block, a clamping groove, a second locking buckle, a groove, a second buckle, a pile hammer, a second buckle, and a sliding rod. The steel pipe pile is clamped vertically to the sea surface, and then the pile driver is lifted up and the clamping block is inserted into the groove from the top of the steel pipe pile. Then, the second locking buckle is engaged with the second buckle in the groove. At this time, the bottom of the pile hammer abuts against the second buckle, so that the pile hammer is connected to the pile driver through the sliding rod. Then, the crane is driven to move the pile hammer up and down, so that the pile hammer strikes the pile driver, thereby sinking the steel pipe pile into the seabed and fixing it. During the up and down movement of the pile hammer, due to the connection with the sliding rod, the movement trajectory of the pile hammer is kept consistent, avoiding the hammer force deviation when the pile hammer contacts the pile driver, thereby improving the pile driving effect of the device.

[0004] In normal use, due to the different specifications of steel pipe piles, the existing design makes it inconvenient for the clamp to abut against the inner wall of steel pipe piles of different specifications when driving them. This restricts the position and angle of the driving device, making it easy for the device to deviate when driving steel pipe piles of different specifications, thus making it inconvenient for the device to drive steel pipe piles of different specifications. Utility Model Content

[0005] The purpose of this utility model is to provide a marine pile driving device that solves the problem that, due to the different specifications of steel pipe piles, the existing design makes it inconvenient for the locking block to abut against the inner wall of steel pipe piles of different specifications when driving piles of different specifications. This restricts the position and angle of the driving device, making it easy for the device to deviate when driving piles of different specifications, thus making it inconvenient for the device to drive piles of different specifications.

[0006] To achieve the above objectives, this utility model provides a marine pile driving device, including a pile driver and structural components. The structural components include a pile hammer, a sliding rod, a locking block, a base block, a slider, an adjusting screw, a buckle, and a driving component. The base block is fixedly installed on one side of the pile driver. The driving component is connected to the base block. The adjusting screw is rotatably connected to the base block and connected to the driving component. The slider is slidably connected to the base block and threadedly connected to the adjusting screw. The locking block is slidably connected to the base block and fixedly connected to the slider. The sliding rod is fixedly installed on the side of the pile driver away from the base block. The pile hammer is slidably connected to the sliding rod and located on the side of the sliding rod away from the base block. The buckle is fixedly connected to the pile hammer and located on the side of the pile hammer away from the pile driver.

[0007] The driving component includes a horizontal block and a block body. The horizontal block is rotatably connected to the bottom block and fixedly connected to the adjusting screw. The block body is rotatably connected to the bottom block and fixedly connected to the horizontal block.

[0008] The bottom block has a groove located on the side of the bottom block near the slider and engages with the slider.

[0009] The structural component further includes a counterweight, a limiting block, and mounting bolts. The limiting block is fixedly connected to the pile hammer and is located on the side of the pile hammer away from the slide bar. The counterweight is detachably connected to the limiting block. The mounting bolts are threadedly connected to the counterweight.

[0010] The mounting bolt includes a mounting screw and a mounting nut. The mounting screw is threaded to the counterweight and is located on the side of the counterweight away from the pile hammer. The mounting nut is threaded to the mounting screw and abuts against the counterweight.

[0011] This utility model discloses a marine pile driving device. The mounting screw and mounting nut cooperate to fix the counterweight block onto the limiting block, thereby increasing the weight of the pile hammer. Workers insert tools into the block and rotate it, driving the block to rotate the horizontal block on the base block. When the horizontal block rotates, it drives the adjusting screw to rotate on the base block. When the adjusting screw rotates, it drives the slider to move the locking block on the base block, adjusting the position of the locking block. The pile driver, with the locking block, is then placed on the steel pipe pile. Simultaneously, the locking block abuts against the inner wall of the steel pipe pile, limiting the position and angle of the pile driver. External equipment lifts the pile hammer. When the pile hammer is lowered, it moves on the sliding rod, impacting the pile driver and causing the steel pipe pile to sink to the seabed. This prevents the device from shifting when driving steel pipe piles of different specifications, thus facilitating the driving of steel pipe piles of various sizes. Attached Figure Description

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The first embodiment of this application is as follows:

[0020] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of the marine pile driving device according to the first embodiment of this utility model. Figure 2 This is a structural schematic diagram of the pile driver and sliding rod of this utility model. Figure 3 This is a utility model Figure 2 Enlarged view at point A Figure 4 This is a schematic diagram of the installation screw and installation nut of this utility model. This utility model provides a marine pile driving device 101, including a pile driver 101 and structural components. The structural components include a pile hammer 102, a sliding rod 103, a locking block 104, a bottom block 105, a slider 106, an adjusting screw 107, a buckle 108, a driving component, a counterweight 109, a limiting block 110, and an installation bolt 111. The installation bolt 111 includes an installation screw 112 and an installation nut 113. The driving component includes a horizontal block 114 and a block 115. The bottom block 105 has a groove 116. The aforementioned solution addresses the problem in existing designs where, when driving steel pipe piles of different specifications, the locking block 104 is inconvenient to abut against the inner wall of the steel pipe piles of different specifications, thus limiting the position and angle of the pile driver 101. This makes the device prone to deviation when driving steel pipe piles of different specifications, making it inconvenient for the device to drive steel pipe piles of different specifications. It is understood that the aforementioned solution can be used when the locking block 104 is inconvenient to abut against the inner wall of the steel pipe piles of different specifications due to the different specifications of the steel pipe piles.

[0021] In this specific embodiment, the driving component drives the adjusting screw 107 to rotate on the base block 105. When the adjusting screw 107 rotates, it drives the slider 106 to move the locking block 104 on the base block 105, adjusting the position of the locking block 104 on the base block 105. The pile driver 101 then moves the locking block 104 onto the steel pipe pile, while the locking block 104 abuts against the inner wall of the steel pipe pile, restricting the position and angle of the pile driver 101. An external device lifts the pile hammer 102. When the pile hammer 102 is lowered, it moves on the sliding rod 103 to impact the pile driver 101, thereby impacting the steel pipe pile and sinking it to the seabed. This prevents the device from deviating when driving steel pipe piles of different specifications, thus making the device convenient for driving steel pipe piles of different specifications.

[0022] The base block 105 is fixedly installed on one side of the pile driver 101. The driving component is connected to the base block 105. The adjusting screw 107 is rotatably connected to the base block 105 and connected to the driving component. The slider 106 is slidably connected to the base block 105 and threadedly connected to the adjusting screw 107. The locking block 104 is slidably connected to the base block 105 and fixedly connected to the slider 106. The sliding rod 103 is fixedly installed on the side of the pile driver 101 away from the base block 105. The pile hammer 102 is slidably connected to the sliding rod 103 and located on the side of the sliding rod 103 away from the base block 105. The buckle 10... 8 is fixedly connected to the pile hammer 102 and located on the side of the pile hammer 102 away from the pile feeder 101. The bottom of the base block 105 is designed with multiple sliding grooves. There are multiple sliders 106, and the side of the slider 106 is designed with a through threaded hole. The outer side of the slider 106 is slidably connected to the sliding groove of the base block 105. There are multiple locking blocks 104, and the top of the locking blocks 104 is fixedly connected to the bottom of the slider 106. There are multiple adjusting screws 107, and the outer side of the adjusting screws 107 is designed with external threads. The end of the adjusting screw 107 is rotatably connected to the sliding groove of the base block 105 through the through threaded hole of the slider 106. The pile feeder... The bottom end of the device 101 is fixedly connected to the top end of the base block 105. The bottom end of the pile hammer 102 is designed with a sliding cavity. The bottom end of the sliding rod 103 is fixedly connected to the top end of the pile feeder 101. The upper outer part of the sliding rod 103 is slidably connected to the sliding cavity of the pile hammer 102. There are multiple buckles 108. The buckles 108 are located at the top end of the pile hammer 102. The buckles 108 are connected to the pile feeder 101 by steel cables or steel ropes. The buckles 108 drive the pile hammer 102 to rise and fall. The adjusting screw 107 is driven to rotate on the base block 105 by the driving component. When the adjusting screw 107 rotates, it drives the slider 106 to move the pile feeder 102. The locking block 104 moves on the base block 105, adjusting its position on the base block 105. This allows the pile driver 101 to move the locking block 104 onto the steel pipe pile. Simultaneously, the locking block 104 abuts against the inner wall of the steel pipe pile, restricting the position and angle of the pile driver 101. External equipment lifts the pile hammer 102. When the pile hammer 102 is lowered, it moves on the sliding rod 103, impacting the pile driver 101 and causing the steel pipe pile to sink into the seabed. This prevents the device from shifting when driving steel pipe piles of different specifications, thus facilitating the driving of steel pipe piles of different specifications.

[0023] Secondly, the horizontal block 114 is rotatably connected to the bottom block 105 and fixedly connected to the adjusting screw 107; the block 115 is rotatably connected to the bottom block 105 and fixedly connected to the horizontal block 114. The bottom block 105 has multiple rotating cavities on its outer side. The outer side of the closed end of the block 115 and the outer side of the horizontal block 114 are rotatably connected to the rotating cavities of the bottom block 105. One side of the horizontal block 114 is fixedly connected to the outer side of the closed end of the block 115, and the other side of the horizontal block 114 is fixedly connected to the end of the adjusting screw 107. When the operator inserts a tool into the block 115 and rotates it, the block 115 drives the horizontal block 114 to rotate on the bottom block 105. When the horizontal block 114 rotates, it drives the adjusting screw 107 to rotate, thereby driving the adjusting screw 107 to rotate on the base.

[0024] Then, the bottom block 105 has a sliding groove 116, which is located on the side of the bottom block 105 near the slider 106 and cooperates with the slider 106. There are multiple sliding grooves 116, which are located at the bottom of the bottom block 105. The sliding groove 116 is slidably connected to the outer side of the slider 106. By driving the slider 106 to move on the sliding groove 116, the connection between the bottom block 105 and the slider 106 is realized.

[0025] Meanwhile, the limiting block 110 is fixedly connected to the pile hammer 102 and located on the side of the pile hammer 102 away from the slide rod 103; the counterweight block 109 is detachably connected to the limiting block 110; the mounting bolt 111 is threadedly connected to the counterweight block 109; the end of the limiting block 110 is hollow; the inner side of the limiting block 110 is fixedly connected to the lower outer side of the pile hammer 102; there are multiple counterweight blocks 109; the end of each counterweight block 109 is designed with a through hole; the inner side of each counterweight block 109 is designed with a mounting groove; the counterweight... The outer side of block 109 is designed with multiple mounting holes. The mounting groove of the counterweight block 109 is detachably connected to the outer side of the limiting block 110. There are multiple mounting bolts 111. The mounting bolts 111 install the two counterweight blocks 109 onto the limiting block 110 through the mounting holes of the two counterweight blocks 109. By installing the counterweight blocks 109 onto the limiting block 110 through the mounting bolts 111, the weight of the pile hammer 102 is increased, thereby increasing the impact effect of the pile hammer 102 when it hits the pile feeder 101.

[0026] Finally, the mounting screw 112 is threadedly connected to the counterweight 109 and is located on the side of the counterweight 109 away from the pile hammer 102; the mounting nut 113 is threadedly connected to the mounting screw 112 and abuts against the counterweight 109. The mounting screw 112 is connected to the mounting nut 113 through the mounting hole of the counterweight 109. By cooperating with the mounting screw 112 and the mounting nut 113, the counterweight 109 is fixed to the limiting block 110.

[0027] When using the offshore pile driver 101 of this embodiment, the mounting screw 112 cooperates with the mounting nut 113 to fix the counterweight 109 onto the limiting block 110, thereby increasing the weight of the pile hammer 102. The operator inserts a tool into the block 115 and rotates it, driving the block 115 to rotate the horizontal block 114 on the base block 105. When the horizontal block 114 rotates, it drives the adjusting screw 107 to rotate on the base block 105. When the adjusting screw 107 rotates, it drives the slider 106 to move the locking block 104 on the base block 105. The position of the locking block 104 on the base block 105 is adjusted so that the pile driver 101 moves the locking block 104 onto the steel pipe pile. At the same time, the locking block 104 abuts against the inner wall of the steel pipe pile, restricting the position and angle of the pile driver 101. The external equipment lifts the pile hammer 102. When the pile hammer 102 is lowered, it moves on the slide rod 103 and impacts the pile driver 101, thereby impacting the steel pipe pile and sinking it to the seabed. This prevents the device from deviating when driving steel pipe piles of different specifications, thus making it easy to drive steel pipe piles of different specifications.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
