Abstract
Description
Technical Field
[0001] This utility model relates to a guiding device, specifically a vibratory hammer guiding device for driving Larssen sheet piles, belonging to the field of Larssen sheet pile construction technology. Background Technology
[0002] Larssen sheet piles, also known as U-shaped Larssen sheet piles, are a new type of building material that plays a vital role in engineering projects such as bridge cofferdams, large pipeline laying, and temporary ditch excavation as retaining walls, water barriers, and sand barriers; and in docks, unloading yards, and as retaining walls, embankments, and riverbank protection. Using Larssen sheet piles for cofferdams is not only green and environmentally friendly, but also allows for fast construction, low construction costs, and excellent waterproofing.
[0003] A Larssen sheet pile driving guide device disclosed in Chinese Patent Application Publication CN220377281U describes a process where two guide frames are first installed, and their positions are adjusted using a level to ensure the device is horizontal. Then, the positions of two limiting plates are adjusted using a nut and screw, ensuring the cavity width between the limiting plates matches the width of the two Larssen sheet piles. Finally, the Larssen sheet piles are sequentially placed into the guide cavity from top to bottom and driven, ensuring proper engagement between adjacent sheets. Compared to existing technologies, this patent, through its combination of guide frames, screws, limiting plates, nuts, and a tubular level, provides a Larssen sheet pile driving guide device that can adjust and ensure accurate installation of the sheet piles, resulting in straighter piles, better engagement between adjacent piles, reusability, and reduced construction costs.
[0004] The above-mentioned patented solution can adjust and ensure the accurate installation position of Larssen sheet piles, making the Larssen sheet piles relatively straight and the interlocking degree between adjacent Larssen sheet piles good. However, this process requires the cooperation of multiple nuts and screws to adjust the position of the two limiting plates. It requires repeated operation during use, resulting in low construction efficiency.
[0005] Therefore, a vibratory hammer driving Larssen sheet pile guide device is proposed here. Utility Model Content
[0006] This invention proposes a vibratory hammer driving Larssen sheet pile guiding device, which enables rapid adjustment of the distance between two limiting plates, improves the adjustment speed and avoids repetitive and tedious operations, and significantly improves subsequent construction efficiency.
[0007] This utility model is achieved through the following technical solution: a vibratory hammer driving Larssen steel sheet pile guide device, comprising two guide frames, wherein the guide frames are provided with a limiting component and a stabilizing component.
[0008] The limiting assembly includes a bidirectional screw rotatably connected inside the left guide frame, with one end of the bidirectional screw extending to the outside of the guide frame. A first throttle is fixed to the end of the bidirectional screw extending to the outside of the guide frame. Two limiting plates are installed on the outer surface of the bidirectional screw. Two fixing plates are fixed to the side of the two limiting plates that are close to each other. Multiple mounting rods are fixed to the side of the two fixing plates that are close to each other. A guide roller is rotatably connected to the outer surface of the mounting rod. An elastic pad is provided on the outer surface of the guide roller.
[0009] Furthermore, a sliding rod is fixed inside the right guide frame, and the outer surface of the sliding rod is slidably connected to the inner wall of the hole on the limiting plate.
[0010] Furthermore, a first guide rod is fixed inside each of the two guide frames, and the outer surface of the first guide rod is slidably connected to the inner wall of the hole on the limiting plate.
[0011] Furthermore, both guide frames are equipped with casters on their bottom surfaces, and the casters have brakes installed inside.
[0012] Furthermore, the stabilizing component includes a support plate fixed to one side of the two guide frames that are far apart from each other. A threaded rod is threadedly connected to the inner wall of a hole in the support plate. A second throttle is fixed to the top of the threaded rod, and a mounting plate is rotatably connected to the bottom of the threaded rod. Multiple tapered rods are fixed to the bottom surface of the mounting plate.
[0013] Furthermore, a second guide rod is fixed to the upper surface of the mounting plate, and the outer surface of the second guide rod is slidably connected to the inner wall of the hole on the support plate.
[0014] This utility model provides a guide device for vibratory hammer driving Larssen steel sheet piles, which has the following beneficial effects:
[0015] 1. This vibratory hammer guide device for driving Larssen sheet piles uses a first throttle to rotate a bidirectional screw. The rotation of the bidirectional screw causes two limiting plates to move closer or further apart, ensuring the cavity width between the guide rollers on the two limiting plates matches the width of the two Larssen sheet piles. This allows for rapid adjustment of the distance between the two limiting plates, increasing adjustment speed and avoiding repetitive, tedious operations, significantly improving subsequent construction efficiency. The vibratory hammer then clamps the Larssen sheet piles from top to bottom into the guide cavity, ensuring accurate installation and proper engagement between adjacent Larssen sheet piles. The sheet piles are then inserted into the ground, with the guide rollers guiding them during insertion to improve smoothness.
[0016] 2. The vibratory hammer driving Larssen sheet pile guide device, through the set universal wheels, can move the device to the required position. Then, by rotating the second throttle, the threaded rod is moved. The threaded rod can drive the tapered rod to insert into the ground through the mounting plate. When the two guide frames perform the same operation respectively, the controllability of the threaded transmission can make the mounting plates on both sides contact the ground at the same time, thereby achieving synchronous stability of the two guide frames in actual use and reducing the phenomenon of displacement during construction.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0026] Please see Figures 1-4 The present invention proposes the following implementation scheme: a vibratory hammer driving Larssen steel sheet pile guide device, including two guide frames 1, and a limiting component 2 and a stabilizing component 3 are provided on the guide frame 1.
[0027] Both guide frames 1 are equipped with casters 101 on their bottom surfaces, and the casters 101 are equipped with brakes. The device can be moved to the required position by means of the casters 101.
[0028] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The limiting component 2 includes a bidirectional screw 201 rotatably connected inside the left guide frame 1, with one end of the bidirectional screw 201 extending to the outside of the guide frame 1. A first throttle 202 is fixed to the end of the bidirectional screw 201 extending to the outside of the guide frame 1. Two limiting plates 203 are installed on the outer surface of the bidirectional screw 201. Two fixing plates 204 are fixed on the side of the two limiting plates 203 that are close to each other. Multiple mounting rods 205 are fixed on the side of the two fixing plates 204 that are close to each other. A guide roller 206 is rotatably connected to the outer surface of the mounting rod 205. An elastic pad is provided on the outer surface of the guide roller 206.
[0029] A slide rod 207 is fixed inside the right guide frame 1, and the outer surface of the slide rod 207 is slidably connected to the inner wall of the hole on the limiting plate 203.
[0030] Both guide frames 1 have a first guide rod 208 fixed inside, and the outer surface of the first guide rod 208 is slidably connected to the inner wall of the hole on the limiting plate 203.
[0031] Rotating the first throttle 202 drives the bidirectional screw 201 to rotate. The rotation of the bidirectional screw 201 causes the two limiting plates 203 to move closer or further apart, making the cavity width between the guide rollers 206 on the two limiting plates 203 the same as the width of the two Larssen sheet piles. This achieves rapid adjustment, increases adjustment speed, avoids repetitive and tedious operations, and significantly improves construction efficiency. Then, the Larssen sheet piles are clamped into the guide cavity from top to bottom by the vibratory hammer device to ensure the accurate installation position of the Larssen sheet piles. Adjacent Larssen sheet piles are secured to each other. Then, they are inserted into the ground. During the insertion of the Larssen sheet piles into the ground, the guide rollers 206 guide them, improving their smoothness and construction efficiency.
[0032] Please refer to this carefully. Figure 3 The stabilizing component 3 includes a support plate 301 fixed to one side of the two guide frames 1 that are far apart from each other. A threaded rod 302 is threadedly connected to the inner wall of the hole on the support plate 301. A second throttle 305 is fixed to the top of the threaded rod 302. A mounting plate 303 is rotatably connected to the bottom of the threaded rod 302. A plurality of tapered rods 304 are fixed to the bottom surface of the mounting plate 303.
[0033] The upper surface of the mounting plate 303 is fixed with a second guide rod 306, and the outer surface of the second guide rod 306 is slidably connected to the inner wall of the hole on the support plate 301.
[0034] By rotating the second throttle 305, the threaded rod 302 is moved. The threaded rod 302 can drive the tapered rod 304 to insert into the ground through the mounting plate 303. When the two guide frames 1 perform the same operation, the controllability of the threaded transmission allows the mounting plates 303 on both sides to contact the ground simultaneously, thereby achieving synchronous stability of the two guide frames 1 in actual use and reducing displacement during construction.
[0035] In use, this invention involves moving the device to the desired position using the casters 101, then rotating the second handle 305 to move the threaded rod 302. The threaded rod 302, via the mounting plate 303, drives the tapered rod 304 to insert into the ground. When both guide frames 1 perform the same operation, the controllability of the threaded transmission ensures that both mounting plates 303 simultaneously contact the ground, achieving synchronous stability of the two guide frames 1 and reducing displacement during construction. Then, rotating the first handle 202 drives the bidirectional screw 201 to rotate. The rotation of the bidirectional screw 201... The kinetic energy drives the two limiting plates 203 to move closer or further apart, so that the cavity width between the guide rollers 206 on the two limiting plates 203 is the same as the width of the two Larssen sheet piles, thereby achieving rapid adjustment, improving the adjustment speed and avoiding repetitive and tedious operations, significantly improving construction efficiency. Then, the Larssen sheet piles are clamped into the guide cavity from top to bottom by the vibratory hammer device to ensure the accurate installation position of the Larssen sheet piles. Adjacent Larssen sheets ensure their interlocking, and then they are inserted into the ground. During the process of inserting the Larssen sheet piles into the ground, the guide rollers 206 will guide them to improve their smoothness.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
