Description

Technical Field

[0001] The present application relates to the field of geological survey technology, and in particular to an amphibious platform CPTU system and a construction method thereof. Background Art

[0002] Coastal tidal flats are the transition zone between the ocean and the land, with rich natural resources and geographical functions. They can be used for the construction of tidal flat photovoltaic, tidal flat wind power, highway bridges, port terminals and other engineering projects. However, due to the special hydrogeological environment of tides and deep soft soil layers, the construction of coastal tidal flats is difficult.

[0003] The development and construction of coastal tidal flat projects require preliminary geological surveys. Cone Penetration Test Tuning (CPTU) is a geological survey technology that can perform in-situ testing on soil. The stratigraphic data detected by CPTU is continuous and reliable, and the soil layers can be accurately divided. It also has the advantages of fast construction speed, labor-saving operation, and high economy. The CPTU survey of coastal tidal flats requires the support of a construction operation platform, such as the amphibious geotechnical engineering survey platform disclosed in the prior art, which uses a crawler walking device to achieve walking on land and tidal flat environments. However, due to the soft and thick silt on the tidal flat, the crawler walking device is prone to slipping when walking on the tidal flat, affecting the efficiency of the survey operation. Summary of the invention

[0004] In order to solve the problem that the crawler walking device of the existing amphibious geotechnical engineering survey platform is prone to slipping when walking on the tidal flat area, the present application provides an amphibious platform type CPTU system and a construction method thereof.

[0005] The present application provides an amphibious platform CPTU system that adopts the following technical solutions:

[0006] A CPTU system of an amphibious platform type comprises a floating platform body, a crawler walking device and a CPTU device, wherein the crawler walking device comprises a crawler, and the crawler comprises continuously arranged crawler shoes; the crawler is provided with a soil-moving mechanism, and the soil-moving mechanism comprises a plurality of swinging shovel plates, each of which is connected to one of the crawler shoes respectively, and the swinging shovel plates and the crawler shoes are staggered along the width direction of the crawler, and each of the crawler shovel plates is commonly connected to a swing adjustment mechanism, and the swing adjustment mechanism is used to simultaneously adjust the swing angle of each of the swinging shovel plates, when the swinging shovel plates are located at the upper limit position of the swing angle, the swinging shovel plates are located within the contour area of ​​the crawler in the vertical plane, and when the swinging shovel plates are located at the lower limit position of the swing angle, the swinging shovel plates partially extend out of the range of the outer contour boundary of the crawler, and the angle between the swinging shovel plates and the crawler shoes is tangential to the cyclic motion of the crawler.

[0007] By adopting the above technical scheme, the amphibious platform CPTU system can enter the water area near the tidal flat after passing through the tidal flat through the crawler walking device, so that the amphibious platform CPTU system can conduct underwater soil survey work; when the amphibious platform CPTU system needs to walk on the tidal flat, the swing angle of each swing shovel plate can be adjusted by the swing adjustment mechanism, so that the swing shovel plate part extends out of the range of the outer contour boundary of the crawler, and the angle between the swing shovel plate and the track plate is tangential to the cyclic motion of the crawler, so that when the crawler is walking, the swing shovel plate can form a shoveling effect on the silt on the tidal flat, so that the swing shovel plate and the silt on the tidal flat form a mutual thrust, thereby reducing the slipping of the crawler walking device when walking on the tidal flat; when it is necessary to make the amphibious platform CPTU system walk on land, the swing adjustment mechanism is used to adjust each swing shovel plate to the upper limit position, and when the crawler is walking on land, the swing shovel plate can reduce the impact of the swing shovel plate on the ground.

[0008] Optionally, a swing plate is connected to one side of the swing shovel plate, and the angle between the swing plate and the swing shovel plate is an obtuse angle; two clamping plates are fixedly provided on the side of the track shoe away from the ground contacting side, and the two clamping plates extend beyond the surface range of the track shoe, and the swing plate is located between the two clamping plates, and the gap between the two clamping plates is greater than the thickness of the swing plate.

[0009] By adopting the above technical solution, the swing plate is located between the two clamping plates, and the gap between the two clamping plates is greater than the thickness of the swing plate, so that the swing plate has a certain degree of swing freedom between the two clamping plates, so that the swing shovel plate connected to the swing plate can swing. Compared with the swing adjustment achieved by rotating connection in conventional technical means, the matching gap between the swing plate and the two clamping plates is larger, and it is not easy to get stuck in a muddy environment.

[0010] Optionally, two limit plates are connected between the two clamps, and the two limit plates and the two clamps together form a flat frame-shaped structure; the swing plate includes a connecting portion and an abutting portion, the connecting portion is used to connect the swing shovel plate, and the abutting portion is used to abut the side of the corresponding track plate away from the ground contacting side, and a spacing margin is left between the edge of the abutting portion close to one side of the swing shovel plate and the swing shovel plate.

[0011] By adopting the above technical scheme, the two limit plates limit the displacement of the swing plate and the swing shovel plate combination along the width direction of the track. At the same time, the abutting portion of the swing plate abuts against the track plate, making it difficult for the swing plate and the swing shovel plate combination to separate from the two clamping plates, thereby making the position of the swing plate and the swing shovel plate combination relatively stable; on the other hand, by leaving a gap margin between the edge of the abutting portion close to one side of the swing shovel plate and the swing shovel plate, a certain gap margin can be formed between the swing shovel plate and the two clamping plates, so that the swing shovel plate can swing.

[0012] Optionally, the swing adjustment mechanism includes a rope, which is sequentially connected to each of the swing plates, and the rope is located inside the range of the outer contour boundary of the track. The rope is fixed with a first magnet, and one of the track plates of the track is provided with two second magnets, and the second magnets are located on the side of the track plate away from the ground contacting side. When the first magnet is attracted to one of the second magnets, each of the swing shovel plates is located at the upper limit position of the swing angle, and when the first magnet is attracted to another of the second magnets, each of the swing shovel plates is located at the lower limit position of the swing angle.

[0013] By adopting the above technical solution, the rope is connected in series with each swing plate in sequence, and by making the first magnet on the rope attract different second magnets, the rope can drive the swing shovel plate to swing to the upper limit or lower limit, thereby realizing the angle adjustment of the swing shovel plate. The thrust of the mud on the swing shovel plate is resisted by the clamp support, and the rope is only used to adjust the angle of the swing shovel plate, so that the first magnet and the second magnet are not easily separated from each other due to the reverse thrust of the mud. The rope is positioned by the magnetic attraction between the first magnet and the second magnet, and the connection structure is simple, and it is not easy to fail in the muddy and water-rich environment of the mudflat.

[0014] Optionally, a guide plate is provided on the side of the track shoe facing away from the ground contacting side, and the guide plate is provided with a guide hole for the rope to pass through.

[0015] By adopting the above technical solution, the guide plate has a guiding effect on the rope, so that the rope maintains a relatively stable shape during the cyclic rotation of the crawler track.

[0016] Optionally, a propeller mechanism is provided at the lower portion of the floating platform body, and a guide mechanism is provided on the side of the floating platform body away from the propeller mechanism, the guide mechanism includes two guide triangles, the two guide triangles are respectively hinged to the floating platform body, and the hinged side edges of the two guide triangles are gradually inclined and approached to each other from top to bottom; when the downward edges of the two guide triangles abut against each other, the two guide triangles are connected by a connecting rod, and the connecting rod includes a cross bar and a longitudinal rod located at both ends of the cross bar, and the upward edges of the two guide triangles are provided with sockets for the longitudinal rods to be plugged in; when the two guide triangles are folded with each other, the two guide triangles are connected by a fork-shaped positioning piece, and the fork-shaped positioning piece is simultaneously plugged into the two guide triangles, and the fork-shaped positioning piece is located between the upward sharp corners of the two guide triangles in the folded state.

[0017] By adopting the above technical solution, when the floating platform body of the amphibious platform CPTU system floats in the sea water, it can be driven to navigate by the propeller mechanism. At this time, the two guide triangles can be unfolded to keep the lower edges of the two guide triangles in contact with each other, and the two guide triangles can be connected by a connecting rod so that the two guide triangles can form a guide effect on the sea water, thereby reducing the resistance of the sea water to the floating platform body; when the amphibious platform CPTU system leaves the water area, the connecting rod can be removed, the two guide triangles can be folded, and the fork-shaped positioning piece can be used to position them, thereby reducing the overall volume of the amphibious platform CPTU system.

[0018] Optionally, the lower edges of the two guide triangles are provided with folded edges, and the folded edges form an obtuse angle with the main body of the guide triangle, and the lower edges of the two guide triangles are abutted in a manner that their respective folded edges fit each other.

[0019] By adopting the above technical solution, the lower edges of the two guide triangles are abutted with each other in a manner that their respective folded edges fit together, thereby increasing the contact area between the two guide triangles, which is beneficial for keeping the lower edges of the two guide triangles in a state of abutting each other, thereby allowing the two guide triangles to support each other to resist the reverse thrust of seawater.

[0020] Optionally, the fork-shaped positioning member includes two outer fork legs and one middle fork leg, and when the fork-shaped positioning member is plugged into the two guide triangles, the middle fork leg is located between the two guide triangles.

[0021] By adopting the above technical solution, when the two guide triangles are overlapped with each other, the folded edge of the inner guide triangle forces a larger gap to be maintained between the two guide triangles; when the fork-shaped positioning piece is simultaneously plugged into the two guide triangles, the middle fork leg of the fork-shaped positioning piece is inserted between the two guide triangles, which helps to reduce the vibration between the two guide triangles due to the excessive gap.

[0022] Optionally, the floating platform body is provided with a plurality of pile leg assemblies, the pile leg assemblies comprising a rotating adjustment seat and a pile leg body, the rotating adjustment seat is rotatably connected to the floating platform body, the floating platform body is provided with a rotating driving member for driving the rotating adjustment seat to rotate around a horizontal axis, and the rotating adjustment seat is provided with a hydraulic mechanism for driving the pile leg body to move axially.

[0023] By adopting the above technical solution, the hydraulic mechanism of the pile leg assembly can drive the pile leg body to be inserted into the mud of the beach, so that the floating platform body can remain stable when in the beach area covered by seawater, which is conducive to the CPTU device to stably perform survey operations. When the floating platform body leaves the flooded area of ​​the beach, the pile leg is rotated to a horizontal state by rotating the rotary adjustment seat to lower the center of gravity of the overall structure of the amphibious platform CPTU system, so as to improve the stability of the amphibious platform CPTU system during movement.

[0024] The construction method of any of the above-mentioned amphibious platform CPTU systems comprises the following steps:

[0025] Step 1: Use the crawler walking device to drive the amphibious platform CPTU system from land to the tidal flat;

[0026] Step 2: Use the swing adjustment mechanism to adjust the swing angle of each swing shovel plate so that the swing shovel plate is located at the lower limit position;

[0027] Step 3: The amphibious platform CPTU system is driven from the tidal flat to the water area near the tidal flat by the crawler walking device, and the soil parameters of the tidal flat area are detected by the CPTU device;

[0028] Step 4: Use the swing adjustment mechanism to adjust the swing angle of each swing shovel. After the swing shovel is at the upper limit position, the amphibious platform CPTU system is driven away from the mudflat by the crawler walking device.

[0029] By adopting the above technical solution, when the amphibious platform CPTU system travels on the tidal flat area through the crawler walking device, the swinging shovel on the crawler can form a mutual thrust with the mud on the tidal flat, thereby reducing the slippage of the crawler.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting a toggle mechanism, when the amphibious platform CPTU system needs to walk on the tidal flat, the swing angle of each swing shovel board can be adjusted through the swing adjustment mechanism, so that when the crawler is walking, the swing shovel board can form a shoveling effect on the silt on the tidal flat, so that the swing shovel board and the silt on the tidal flat form a mutual thrust, thereby reducing the slipping of the crawler walking device when walking on the tidal flat;

[0032] 2. The two guide triangles of the guide mechanism can guide the seawater, reducing the resistance of the seawater to the floating platform when it is moving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-8 This application is described in further detail.

[0043] The present application embodiment discloses an amphibious platform CPTU system and a construction method thereof. Figure 1 and Figure 2The amphibious platform CPTU system includes a floating platform body 1, a CPTU device 3 and a crawler walking device 2; two pile leg assemblies 4 are respectively provided on the opposite sides of the floating platform body 1, a propeller mechanism 5 is provided at the lower part of the floating platform body 1, and the side of the floating platform body 1 away from the propeller mechanism 5 is set as the front side.

[0044] The amphibious platform CPTU system passes through the mudflats and enters the waters near the mudflats through the crawler walking device 2. After entering the waters, the amphibious platform CPTU system travels through the propeller mechanism 5 and is positioned using the pile leg assembly 4 to facilitate stable survey of the soil quality in the flooded area.

[0045] Reference Figure 2 and Figure 3 The crawler walking device 2 is located at the lower part of the floating platform body 1. The crawler walking device 2 includes two crawlers 21. The crawler 21 includes continuously arranged crawler shoes 211. The crawler 21 is provided with a soil-moving mechanism 6. The soil-moving mechanism 6 includes a plurality of swinging shovels 61. The swinging shovels 61 are arranged at equal intervals along the circumference of the crawler 21. Each swinging shovel 61 is connected to a crawler shoe 211 respectively. The swinging shovels 61 and the crawler shoes 211 are staggered along the width direction of the crawler 21. The shovels of each crawler 21 are commonly connected to a swing adjustment mechanism 7. The swing adjustment mechanism 7 is used to simultaneously adjust the swing angles of each swinging shovel 61.

[0046] Reference Figure 4 and Figure 5 When the swing shovel 61 is at the lower limit of the swing angle, part of the swing shovel 61 extends out of the outer contour boundary of the crawler 21, and the angle between the swing shovel 61 and the track shoe 211 is tangential to the cyclic motion of the crawler 21, so that the swing shovel 61 can produce a thrust on the mud on the beach during the cyclic rotation of the crawler 21, so that the mud on the beach produces a reverse thrust on the crawler walking device 2 to reduce the slippage of the crawler 21. When the swing shovel 61 is at the upper limit of the swing angle, the swing shovel 61 is located in the contour area of ​​the crawler 21 in the vertical plane, and the swing shovel 61 is parallel to the corresponding track shoe 211, which can reduce the impact of the swing shovel 61 on the ground when the crawler 21 travels on land.

[0047] Reference Figure 3 and Figure 6 A swing plate 62 is connected to one side of the swing shovel plate 61, and the angle between the swing plate 62 and the swing shovel plate 61 is an obtuse angle; two clamping plates 63 are fixedly provided on the side of the track shoe 211 away from the ground contacting side, and the two clamping plates 63 extend beyond the surface range of the track shoe 211, so that the two clamping plates 63 are in a cantilever state, and the swing plate 62 is located between the two clamping plates 63, and the gap between the two clamping plates 63 is greater than the thickness of the swing plate 62, so that the swing plate 62 can swing between the two clamping plates 63.

[0048] Reference Figure 6 The swing plate 62 partially extends beyond the surface range of the swing shovel plate 61 and abuts against the side of the track shoe 211 away from the ground contact side. The swing plate 62 includes a connecting portion 621 and an abutting portion 622. The connecting portion 621 is used to connect the swing shovel plate 61, and the abutting portion 622 is used to abut against the side of the corresponding track shoe 211 away from the ground contact side. A spacing margin is left between the edge of the abutting portion 622 close to the side of the swing shovel plate 61 and the surface of the swing shovel plate 61, so that a gap margin is formed between the swing shovel plate 61 and the two clamping plates 63 for the swing shovel plate 61 to swing; two limit plates 64 are connected between the two clamping plates 63, and the two limit plates 64 and the two clamping plates 63 together form a flat frame-shaped structure, and the two sides of the swing plate 62 abut against the two limit plates 64 respectively.

[0049] The two limit plates 64 limit the displacement of the swing plate 62 and the swing shovel plate 61 combination along the width direction of the track 21. At the same time, the abutment portion 622 of the swing plate 62 abuts against the track plate 211, making it difficult for the swing plate 62 and the swing shovel plate 61 combination to separate from the two clamping plates 63, thereby making the position of the swing plate 62 and the swing shovel plate 61 combination relatively stable.

[0050] Reference Figure 2 and Figure 3 The swing adjustment mechanism 7 includes a rope 71, and the rope 71 is located inside the range of the outer contour boundary of the crawler 21. The rope 71 is specifically a steel wire rope made of stainless steel. The steel wire rope is connected in series with each swing plate 62 in sequence. The side of the swing plate 62 away from the swing shovel plate 61 is provided with a through hole 623 for the rope 71 to pass through. The through hole 623 is located outside the gap between the two clamping plates 63. The steel wire rope is provided with a plurality of groups of steel wire rope clamps 72. The number of steel wire rope clamps 72 in each group is set to two, and each group of steel wire rope clamps 72 corresponds to one swing plate 62 respectively. The two steel wire rope clamps 72 in the same group are used to clamp the swing plate 62 together.

[0051] Reference Figure 3 Each track shoe 211 is provided with a guide plate 73, and the guide plate 73 is provided with a guide hole 731 through which the feed rope 71 passes. The guide holes 731 of each guide plate 73 jointly guide and shape the steel wire rope, so that the shape of the steel wire rope remains stable.

[0052] Reference Figure 3 The rope 71 is fixed with a first magnet 74, and a track shoe 211 of the track 21 is provided with two second magnets 75. The two second magnets 75 are staggered along the extension direction of the wire rope, and the second magnet 75 is located on the side of the track shoe 211 away from the ground contacting side. The first magnet 74 and the second magnet 75 are both strong neodymium iron boron magnets.

[0053] By pulling the steel wire rope and making the first magnet 74 on the steel wire rope cooperate with different second magnets 75 respectively, the steel wire rope can drive the combination of the swing plate 62 and the swing shovel plate 61 to swing. When the first magnet 74 is attracted with one second magnet 75, each swing shovel plate 61 is located at the upper limit position of the swing angle. When the first magnet 74 is attracted with another second magnet 75, each swing shovel plate 61 is located at the lower limit position of the swing angle, so as to realize the adjustment of the swing angle of the swing shovel plate 61.

[0054] Reference Figure 1 and Figure 7 A flow guide mechanism 8 is provided on the side of the floating platform body 1 away from the propeller mechanism 5. The flow guide mechanism 8 includes two flow guide triangles 81. The two flow guide triangles 81 are respectively hinged to the floating platform body 1, and the hinged side edges of the two flow guide triangles 81 gradually tilt and approach each other from top to bottom; when the downward edges of the two flow guide triangles 81 abut against each other, the two flow guide triangles 81 are connected by a connecting rod 82. The two flow guide triangles 81 are connected by the connecting rod 82. At this time, the two flow guide triangles 81 simultaneously form a tetrahedral space area with the side of the floating platform plate. The two flow guide triangles 81 can form a diversion effect on the seawater in front of the floating platform body 1, which is beneficial to reduce the movement resistance of the floating platform body 1 in the seawater.

[0055] Reference Figure 7 The lower edge of each guide triangle plate 81 is bent in a direction away from the other guide triangle plate 81 to form a folded edge 811, and the folded edge 811 forms an obtuse angle with the main body of the guide triangle plate 81. The lower edges of the two guide triangle plates 81 are abutted against each other in a manner that their respective folded edges 811 fit each other, thereby increasing the contact surface between the two guide triangle plates 81, so as to facilitate the two guide triangle plates 81 to support each other to resist the reverse thrust of seawater.

[0056] Reference Figure 7 The connecting rod 82 includes a crossbar 821 and longitudinal rods 822 located at both ends of the crossbar 821 , and the upward edges of the two guide triangles 81 are provided with plug holes 812 for the longitudinal rods 822 to be plugged in.

[0057] Reference Figure 8 When the two guide triangles 81 are folded against each other, the two guide triangles 81 are connected by a fork-shaped positioning piece 83. The fork-shaped positioning piece 83 is located between the upward pointed corners of the two guide triangles 81 in the folded state. The fork-shaped positioning piece 83 includes two outer fork legs 831 and an intermediate fork leg 832. The intermediate fork legs 832 form insertion gaps 833 with the two outer fork legs 831 respectively. When the fork-shaped positioning piece 83 is plugged into the two guide triangles 81 at the same time, the two guide triangles 81 are inserted into the two insertion gaps 833 respectively.

[0058] The two guide triangles 81 of the guide mechanism 8 can be unfolded or folded. When the two guide triangles 81 are unfolded, the seawater can be guided to reduce the resistance of the floating platform body 1 moving in the seawater. When the two guide triangles 81 are folded, the volume of the amphibious platform CPTU system can be reduced.

[0059] Reference Figure 1 The pile leg assembly 4 includes a rotating adjustment seat 41 and a pile leg body 42. The rotating adjustment seat 41 is rotatably connected to the floating platform body 1. The floating platform body 1 is provided with a rotating driving member 43 for driving the rotating adjustment seat 41 to rotate around a horizontal axis. The rotating driving member 43 is a reduction motor. The rotating adjustment seat 41 is provided with a hydraulic mechanism 44 for driving the pile leg body 42 to move axially.

[0060] When the amphibious platform CPTU system is located in the flooded area of ​​the beach, the rotating adjustment seat 41 drives the pile leg body 42 to rotate to the vertical direction, and then the hydraulic mechanism 44 drives the pile leg body 42 to insert into the beach. The floating platform body 1 is kept stable, which is conducive to keeping the CPTU device 3 stable during the survey operation; when the amphibious platform CPTU system leaves the flooded area of ​​the beach, the rotating adjustment seat 41 can drive the pile leg body 42 to rotate to a horizontal state to lower the overall center of gravity of the amphibious platform CPTU system.

[0061] A construction method of an amphibious platform CPTU system comprises the following steps:

[0062] Step 1: The amphibious platform CPTU system is driven to move from land to the beach by the crawler walking device 2;

[0063] Step 2: Use the swing adjustment mechanism 7 to adjust the swing angle of each swing shovel plate 61 so that the swing shovel plate 61 is located at the lower limit position;

[0064] Step 3: The amphibious platform CPTU system is driven from the tidal flat to the water area near the tidal flat by the crawler walking device 2, and the soil parameters of the flooded area are surveyed by the CPTU device 3;

[0065] Step 4: Use the swing adjustment mechanism 7 to adjust the swing angle of each swing shovel 61. After the swing shovel 61 is located at the upper limit position, the amphibious platform CPTU system is driven away from the mudflat by the crawler walking device 2.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
