Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe pile hoisting, in particular to an embedded steel pipe pile turning device. BACKGROUND

[0002] With the large-scale development of offshore engineering, the application of steel pipe piles is becoming more and more popular. Steel pipe piles are generally manufactured into finished products in land steel pipe pile processing plants, and then transported to offshore construction sites by transport barges for pile sinking. The use of steel pipe piles not only improves the construction efficiency, but also significantly improves the quality and safety of marine infrastructure construction. Steel pipe piles are widely used in offshore construction, covering bridges, wharfs, wind power and other fields, and have become one of the key materials indispensable to marine engineering construction.

[0003] In the prior art, after the steel pipe pile is transported to the offshore construction site by the transport barge, a mounting seat is installed on the surface of the barge board, and a turning rod is hinged on the mounting seat. The turning rod is connected and fixed with the steel pipe pile by bolts, so that the steel pipe pile is hinged on the barge board. Then the other end of the steel pipe pile is lifted by the traveling crane, and the displacement of the traveling crane is coordinated to adjust the steel pipe pile from a horizontal state to a vertical state. Finally, the connection between the steel pipe pile and the turning rod is removed, and the pile sinking operation can be performed. The installation of the mounting seat and the turning rod can limit one end of the steel pipe pile, reduce the possibility of free swinging of the lower end of the steel pipe pile during lifting, and improve the safety of the traveling crane.

[0004] However, when the steel pipe pile is connected with the turning rod by bolts, in order to reduce the structural damage to the steel pipe pile, a connecting lug is usually welded on the outer wall of the steel pipe pile. Since the steel pipe pile is long and heavy, multiple connecting lugs need to be welded, and the connecting lugs are connected to the turning rod by bolts, so that one end of the steel pipe pile is hinged on the mounting seat. This results in the need for operators to disassemble multiple bolts one by one and cut off multiple connecting lugs one by one after the steel pipe pile is lifted to the vertical state, before the pile sinking operation can be performed. This is time-consuming and labor-intensive, and seriously affects the efficiency of the steel pipe pile turning. Therefore, further improvement is needed. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the efficiency of the steel pipe pile turning, the present application provides an embedded steel pipe pile turning device.

[0006] The embedded steel pipe pile turning device provided by the present application adopts the following technical scheme:

[0007] The utility model provides an embedded steel pipe pile turnover device, including mounting seat and turnover rod, one end of turnover rod is hinged on mounting seat, the other end is connected with the limiting disc for inserting into steel pipe pile, the surface of limiting disc is equipped with a plurality of limiting strips, each limiting strip is slid installation in limiting disc and can displace along the radial direction of limiting disc, turnover rod is equipped with drive assembly, drive assembly is used for driving all limiting strips synchronous displacement to resist or separate from the inner peripheral wall of steel pipe pile.

[0008] Through the above technical scheme, through the setting of the limiting disc and the limiting strip, the steel pipe pile is transported to the offshore construction site by the transport barge, the limiting disc of the turnover rod is inserted into the steel pipe pile, then all the limiting strips are driven by the drive assembly to displace away from the center of the limiting disc, so that the limiting strips are tightly connected to the inner peripheral wall of the steel pipe pile, thereby connecting one end of the steel pipe pile to the turnover rod. Then the other end of the steel pipe pile is lifted by the travelling crane, forcing the steel pipe pile to adjust from a horizontal state to a vertical state, and finally the limiting strips are driven to displace towards the center of the limiting disc, so that the steel pipe pile and the turnover rod are disconnected, greatly improving the turnover efficiency of the steel pipe pile.

[0009] Optionally, the drive assembly includes a drive sleeve, a push-pull rod, and a drive member. The drive sleeve is slidably sleeved on the outer peripheral wall of the turnover rod. The number of push-pull rods corresponds to the number of limiting strips. One end of each push-pull rod is hinged to the drive sleeve, and the other end is hinged to a corresponding limiting strip. The drive member is arranged on the drive sleeve to drive the drive sleeve to displace along the axial direction of the turnover rod.

[0010] Through the above technical scheme, the radial displacement of the limiting strip can be effectively controlled by the drive sleeve, the push-pull rod, and the drive member, ensuring that multiple limiting strips can be tightly connected or separated from the inner peripheral wall of the steel pipe pile, thereby realizing the rapid connection and separation of the steel pipe pile, greatly improving the turnover efficiency. At the same time, this mechanical linkage is simple and reliable, reducing the complexity of operation, reducing the failure rate, and improving the stability and reliability of the overall device.

[0011] Optionally, the drive sleeve is sleeved on the outer peripheral wall of the turnover rod and is threadedly connected with the turnover rod. A rotating ring is rotatably mounted on the outer peripheral wall of the drive sleeve. One end of each push-pull rod is hinged to the rotating ring, and the push-pull rod is hinged to the drive sleeve through the rotating ring. The drive member includes a drive disc and a drive rod. The drive disc is coaxially arranged on the outer peripheral wall of the drive sleeve. The drive rod is arranged on the surface of the drive disc away from the limiting disc.

[0012] By adopting the technical scheme, the driving sleeve is threadedly connected with the turnover rod, so that the driving sleeve can move along the axial direction of the turnover rod under the action of the driving member, and then drive the push-pull rod and the limiting strip to move synchronously. The driving disc and the driving rod are arranged to facilitate manual control of the displacement of the driving sleeve by the operator, so that the limiting strip can quickly abut against or be separated from the inner circumferential wall of the steel pipe pile, and the turnover efficiency of the steel pipe pile is effectively improved.

[0013] Optionally, the driving disc is provided with a clamping assembly for clamping the outer circumferential wall of the steel pipe pile.

[0014] By adopting the technical scheme, the clamping assembly on the driving disc can clamp the outer circumferential wall of the steel pipe pile, ensuring firm connection between the steel pipe pile and the turnover rod during turnover, avoiding safety hazards caused by unstable connection, and further improving turnover efficiency and safety.

[0015] Optionally, the clamping assembly comprises two clamping strips arranged around the central axis of the driving disc, and a clamping member arranged between the two clamping strips, the clamping member being used to drive the two clamping strips to approach each other to clamp the outer circumferential wall of the steel pipe pile.

[0016] By adopting the technical scheme, the clamping strips can effectively clamp the outer circumferential wall of the steel pipe pile, ensuring firm connection between the steel pipe pile and the turnover rod during turnover of the steel pipe pile, and avoiding the influence of loosening of the steel pipe pile on turnover efficiency and safety by the combination of the clamping strips and the limiting strip.

[0017] Optionally, the clamping member comprises a connecting sleeve and a connecting screw, the connecting sleeve being rotationally connected to the surface of the driving disc, the number of the connecting screws corresponding to the number of the clamping strips, one end of each connecting screw being connected to the corresponding clamping strip, the other end of each connecting screw penetrating into the connecting sleeve and being threadedly connected with the connecting sleeve, and the thread directions between the connecting sleeve and the two connecting screws being opposite.

[0018] By adopting the technical scheme, the thread directions between the connecting sleeve and the two connecting screws are opposite, so that when the connecting sleeve is rotated, the two connecting screws can simultaneously move inward or outward, so that the two clamping strips approach each other or move away from each other, improving the efficiency and reliability of the turnover operation.

[0019] Optionally, the bottom of the mounting seat is provided with a slide rail, the slide rail being mounted on the ship plate, the length direction of the slide rail being consistent with the length direction of the steel pipe pile in the horizontal state, a sliding seat being slidably mounted on the slide rail, the mounting seat being arranged on the sliding seat, and the mounting seat being slidably mounted on the ship plate through the slide rail.

[0020] Through adoption of the technical scheme, the slide rail and the slide base are arranged, flexible movement of the mounting seat is realized, the mounting seat is placed at one side of the steel pipe pile when the steel pipe pile is connected with the turnover rod, the turnover rod is forced to be in a horizontal state, then the mounting seat is pushed to move towards the steel pipe pile, the turnover rod is inserted into the steel pipe pile, and installation convenience of the overall structure is improved.

[0021] Optionally, the mounting seat comprises a bottom plate and two side plates, the two side plates are fixedly installed on the bottom plate, a rotating roller is arranged between the two side plates, and one end of the turnover rod is hinged to the rotating roller; a limiting frame is detachably connected between the two side plates, and the limiting frame is used to force the turnover rod to keep in a vertical state when the steel pipe pile is hoisted to the vertical state.

[0022] Through adoption of the technical scheme, the limiting frame is arranged on the side plate after the steel pipe pile is hoisted to the vertical state, the limiting frame can limit the turnover rod to keep in the vertical state, and the possibility that the steel pipe pile falls off from the row of hangers when an operator dismounts the steel pipe pile and the turnover rod is reduced. In other words, even if the steel pipe pile is separated from the row of hangers in the vertical state, the limiting frame can still force the steel pipe pile to keep in the vertical state, the possibility that the steel pipe pile falls off to cause damage to the ship plate or the operator is reduced, and the possibility of a safety accident in the pile turning process is greatly reduced.

[0023] In summary, the application has at least one of the following beneficial technical effects:

[0024] 1. Through adoption of the limiting disc and the limiting strips, the limiting disc of the turnover rod is inserted into the steel pipe pile after the steel pipe pile is laid on a transport barge and transported to a sea construction site, then all the limiting strips are driven by the driving assembly to move away from the center of the limiting disc at the same time, the limiting strips are abutted against the inner circumferential wall of the steel pipe pile, one end of the steel pipe pile is connected to the turnover rod, the other end of the steel pipe pile is hoisted by the row of hangers, the steel pipe pile is forced to be adjusted from the horizontal state to the vertical state, the limiting strips are driven to move towards the center of the limiting disc, the steel pipe pile and the turnover rod are separated from each other, and the pile turning efficiency of the steel pipe pile is greatly improved.

[0025] 2. Through adoption of the slide rail and the slide base, flexible movement of the mounting seat is realized, the mounting seat is placed at one side of the steel pipe pile when the steel pipe pile is connected with the turnover rod, the turnover rod is forced to be in a horizontal state, then the mounting seat is pushed to move towards the steel pipe pile, the turnover rod is inserted into the steel pipe pile, and installation convenience of the overall structure is improved.

[0026] 3. By setting the limiting frame, after the steel pipe pile is hoisted to the vertical state, the limiting frame is installed on the side plate, the limiting frame can limit the turnover rod and keep it in the vertical state, reducing the possibility that the steel pipe pile will fall off the row of hoists when the operator disassembles the steel pipe pile and the turnover rod, causing the steel pipe pile to fall off the row of hoists. In other words, even if the steel pipe pile and the row of hoists are separated in an accident, the limiting frame can still force the steel pipe pile to remain in the vertical state, reducing the possibility of injury to the ship plate or personnel caused by the steel pipe pile falling, greatly reducing the possibility of a safety accident during the pile turning process.

DETAILED DESCRIPTION

[0032] The following will be described in detail below Figure 1 - the accompanying drawings Figure 4 The present application will be described in further detail.

[0033] Embodiment 1:

[0034] The embodiment of the present application discloses an embedded steel pipe pile turning device.

[0035] Reference Figure 1 , Figure 2An embedded steel pipe pile turning device includes a mounting base 1 and a turning rod 2. In this embodiment, the mounting base 1 includes a base plate 11 and two side plates 12. The surface of the base plate 11 is horizontally arranged. The two side plates 12 are fixedly installed on the upper surface of the base plate 11. A rotating roller 13 is fixedly installed between the two side plates 12. One end of the turning rod 2 is hinged to the rotating roller 13. The turning rod 2 is hinged to the mounting base 1 through the rotating roller 13.

[0036] Reference Figure 1 , Figure 2 A slide rail 6 is installed at the bottom of the base plate 11. The slide rail 6 is used to install on the ship plate, and the length direction of the slide rail 6 is consistent with the length direction of the steel pipe pile in the horizontal state. A sliding seat 61 is slidably installed on the slide rail 6, and the base plate 11 is fixedly installed on the upper surface of the sliding seat. The mounting seat 1 is slidably installed on the ship plate through the slide rail 6. In this embodiment, multiple positioning holes 62 are opened on the slide rail 6, and the multiple positioning holes 62 are arranged at intervals along the length direction of the slide rail 6. The slide rail 6 is provided with positioning pins 63 inserted into the positioning holes 62. In practical applications, two positioning pins 63 are inserted on both sides of the base plate 11 to limit the base plate 11. The slide rail 6 restricts the free sliding of the base plate 11 through the two positioning pins 63.

[0037] Reference Figure 2 The end of the flipping rod 2 away from the rotating roller 13 is fixedly connected to a limiting plate 3 for insertion into the steel pipe pile. The limiting plate 3 and the flipping rod 2 are coaxially arranged. The surface of the limiting plate 3 near the flipping rod 2 is provided with multiple sliding grooves. The multiple sliding grooves are arranged at intervals around the central axis of the limiting plate 3. Both ends of each sliding groove are arranged radially along the limiting plate 3. Multiple limiting strips 31 are installed on the surface of the limiting plate 3. The multiple limiting strips 31 are correspondingly arranged with the multiple sliding grooves. Each limiting strip 31 is slidably installed in the corresponding sliding groove so that it can be displaced radially along the limiting plate 3.

[0038] Reference Figure 1 , Figure 2 The flipping rod 2 is equipped with a driving assembly 4, which is used to drive all the limiting strips 31 to move synchronously to abut against or disengage from the inner circumferential wall of the steel pipe pile. The driving assembly 4 includes a driving sleeve 41, a push-pull rod 42, and a driving component. The driving sleeve 41 is sleeved on the outer circumferential wall of the flipping rod 2 and threadedly connected to the flipping rod 2 (the thread is not shown in the figure). The outer circumferential wall of the driving sleeve 41 has a rotating groove, which is annular around the central axis of the driving sleeve 41. A rotating ring 411 is rotatably installed in the rotating groove. The number of push-pull rods 42 corresponds to the number of limiting strips 31. One end of each push-pull rod 42 is hinged to the outer circumferential wall of the rotating ring 411 of the driving sleeve 41, and the other end is hinged to the corresponding limiting strip 31. The push-pull rod 42 is hinged to the driving sleeve 41 through the rotating ring 411.

[0039] Reference Figure 1 , Figure 2The driving component is disposed on the driving sleeve 41 to drive the driving sleeve 41 to move axially along the flipping rod 2. The driving component includes a driving disk 43 and a driving rod 44. The driving disk 43 is coaxially fixed to the outer peripheral wall of the end of the driving sleeve 41 away from the limiting disk 3, and the driving rod 44 is fixedly installed on the surface of the driving disk 43 away from the limiting disk 3.

[0040] Reference Figure 1 , Figure 2 A support rod 14 is installed between the two side plates 12. The two ends of the support rod 14 are fixedly connected to the two side plates 12. The support rod 14 is used to support the flipping rod 2. When the flipping rod 2 abuts against the support rod 14, the length direction of the flipping rod 2 rotates to a horizontal state.

[0041] The implementation principle of Embodiment 1 of this application is as follows: After the steel pipe pile is transported to the offshore construction site by a transport barge, the mounting seat 1 is pushed to slide along the length of the slide rail 6 to force the limiting plate 3 to be inserted into the steel pipe pile and the mounting seat 1 is limited by the positioning pin 63; then the drive sleeve 41 is rotated to force the drive sleeve 41 to move closer to the limiting plate 3. The drive sleeve 41 can drive all the limiting strips 31 to slide synchronously through multiple push-pull rods 42 and press against the inner peripheral wall of the steel pipe pile to realize the rapid connection between the steel pipe pile and the flipping rod 2.

[0042] Next, the other end of the steel pipe pile is lifted by a gantry crane, forcing the steel pipe pile to change from a horizontal state to a vertical state. Finally, the limiting bar 31 is driven to move towards the center of the limiting plate 3, which can separate the steel pipe pile from the flipping rod 2, greatly improving the flipping efficiency of the steel pipe pile.

[0043] Example 2:

[0044] This application discloses an embedded steel pipe pile turning device.

[0045] Reference Figure 3 The difference between the embedded steel pipe pile turning device disclosed in this application and Embodiment 1 is that:

[0046] In this embodiment, the drive disk 43 is provided with a clamping component 5, which is used to clamp the outer peripheral wall of the steel pipe pile. The clamping component 5 includes clamping strips 51 and clamping members. Two clamping strips 51 are arranged around the central axis of the drive disk 43. The two clamping strips 51 are slidably installed on the surface of the drive disk 43 away from the limiting disk 3, and can move closer to each other or further away from each other. The ends of the two clamping strips 51 that are far away from each other are integrally formed with an extension portion 511. The end of the extension portion 511 away from the clamping strip 51 extends to the outside of the steel pipe pile.

[0047] Reference Figure 3The clamping member is arranged between the two clamping strips 51, and the clamping member is used to drive the two clamping strips 51 to approach each other to clamp the outer peripheral wall of the steel pipe pile; the mounting strip 512 is fixedly installed on the side wall of each clamping strip 51 away from the extension part 511, the clamping member comprises a connecting sleeve 52 and a connecting screw 53, the connecting sleeve 52 is rotationally connected to the surface of the driving disc 43 away from the limiting disc 3, the number of the connecting screws 53 corresponds to the number of the clamping strips 51, one end of each connecting screw 53 is fixedly connected to the mounting strip 512 of the corresponding clamping strip 51, and the other end penetrates into the connecting sleeve 52 and is in threaded connection with the connecting sleeve 52 (the threads are not shown in the figure); in the embodiment, the threads between the connecting sleeve 52 and the two connecting screws 53 are oppositely arranged.

[0048] The implementation principle of the embodiment 2 of the application is as follows: after the limiting strip 31 abuts against the inner peripheral wall of the steel pipe pile, the connecting sleeve 52 is driven to rotate by the wrench, so that the two clamping strips 51 approach each other to clamp the outer peripheral wall of the steel pipe pile, and the connection between the steel pipe pile and the overturning rod 2 is more stable during the overturning process of the steel pipe pile; the combination of the clamping strip 51 and the limiting strip 31 avoids affecting the pile overturning efficiency and safety due to loosening of the steel pipe pile. In addition, after the driving disc 43 clamps the steel pipe pile through the clamping strip 51, the driving disc 43 is not easy to rotate, so that the limiting strip 31 can maintain the abutting effect on the steel pipe pile.

[0049] Embodiment 3

[0050] The embodiment of the application discloses an embedded steel pipe pile overturning device.

[0051] With reference to Figure 4 The embedded steel pipe pile overturning device disclosed by the embodiment of the application is different from the embodiment 1 in that:

[0052] In the embodiment, the limiting frame 7 is detachably installed between the two side plates 12, and when the steel pipe pile is hung to the vertical state, the limiting frame 7 is used to force the overturning rod 2 to maintain the vertical state; the limiting frame 7 comprises a limiting plate 71 and a limiting rod 72, one end of the limiting rod 72 is fixedly installed on the plate surface of the limiting plate 71, the other end penetrates through the two side plates 12 in sequence and is connected to a limiting nut 73, the limiting nut 73 is sleeved on the limiting rod 72 and is in threaded connection with the limiting rod 72 (the threads are not shown in the figure); the two side plates 12 are provided with penetrating holes through which the limiting rod 72 penetrates.

[0053] With reference to Figure 4 In the embodiment, the number of the limiting rods 72 is two and is arranged in the length direction of the limiting plate 71 in a spaced manner, and the two limiting rods 72 are symmetrically distributed on the two sides of the rotating roller 13; when the overturning rod 2 is rotated to the vertical state, the two limiting rods 72 abut against the outer wall of the overturning rod 2.

[0054] The implementation principle of the embodiment 3 of the application is as follows: after the steel pipe pile is hoisted to the vertical state, the two limiting rods 72 of the limiting plate 71 are sequentially arranged in the penetrating holes of the two side plates 12, and are locked by the limiting nuts 73. The two limiting rods 72 can limit the turnover rod 2, so that the turnover rod 2 remains in the vertical state. When the operator dismounts the steel pipe pile and the turnover rod 2, the possibility that the steel pipe pile falls off from the travelling crane is reduced. In other words, even if the steel pipe pile is separated from the travelling crane in the vertical state, the limiting rod 72 can still force the steel pipe pile to remain in the vertical state, so that the possibility that the steel pipe pile falls off and causes damage to the ship plate or personnel is reduced, and the possibility of safety accidents in the pile turning process is greatly reduced.

[0055] The above is the preferred embodiment of the application, which does not limit the protection scope of the application. Therefore, equivalent changes made according to the structure, shape and principle of the application should be covered in the protection scope of the application.
