Description

Technical Field

[0001] This invention relates to the field of steel pipe pile platform technology, specifically to a deep-sea steep slope bare rock steel pipe pile platform. Background Technology

[0002] Steel pipe pile platforms are common temporary structures in engineering construction. Their structure typically uses portal steel pipe pile foundations at the bottom and Bailey beams or steel profiles on top. In deep-sea, steep-slope, bare rock areas, the erection of steel pipe pile platforms is often necessary to assist in construction.

[0003] Chinese patent document CN110485252B discloses a floating construction platform, comprising multiple steel pipe piles, with multiple prefabricated platform plates installed on the steel pipe piles. A fixing device for securing the platform plate is installed between each steel pipe pile and the platform plate. The fixing device includes a rod prefabricated at the bottom of the platform plate and inserted into the inner cavity of the steel pipe pile, a slot formed in the side wall of the rod, a block slidably connected to the steel pipe pile radially and inserted into the slot, and a driving mechanism for moving the block. The block penetrates the side wall of the steel pipe pile. A blocking mechanism is installed on the platform plate to prevent the block from separating from the slot. A crane lowers the platform plate so that the rod is inserted into the inner cavity of the steel pipe pile. At this time, the truncated cone drives the inclined block to move outward from the steel pipe pile. The movement of the inclined block drives the connecting rod to move, and the movement of the connecting rod pushes the driving block upward. Under the action of the first inclined surface, the driving block drives the block to move towards the slot, thereby engaging the block with the slot.

[0004] The shortcomings of the above-disclosed solution are: although the plug can be inserted into the slot, the slot is not compatible with the plug, so the plug is prone to movement in the slot, resulting in the steel pipe pile and the platform plate not being tightly connected, which can easily lead to loosening and thus cause safety hazards. Summary of the Invention

[0005] This invention provides a deep-sea steep slope bare rock steel pipe pile platform, which can effectively solve the problems in the background art.

[0006] This invention discloses a deep-sea steep-slope exposed rock steel pipe pile platform, comprising multiple steel pipe piles. Multiple workbenches are mounted on the top of each steel pipe pile. Insert rods are fixedly mounted on the bottom of each workbench, and these insert rods engage with the steel pipe piles. Two connecting blocks are fixedly mounted on the top of each steel pipe pile. A first push block is slidably mounted on the bottom of each connecting block, and a first slider is fixedly mounted on the bottom of the first push block. A first spring is fixedly mounted between the first slider and the connecting block. A second push block is vertically slidably mounted within each connecting block. The end of the first push block closest to the second push block is inclined, and the inclined surface of the first push block slidably engages with the bottom of the second push block. The other end of the first push block penetrates the steel pipe pile, and a protrusion is provided on its top. The insert rod slides with the protrusion to drive the first push block to move towards the second push block. A third push block is slidably arranged on the top of the connecting block. A clearance groove is opened on the top of the second push block to avoid the third push block. A pressing block is slidably arranged on the third push block. The top of the second push block is an inclined surface. The inclined surface of the second push block slides with the pressing block. A third slider is fixedly arranged on the third push block. A third spring is fixedly arranged between the third slider and the pressing block. A second slot is opened on the side wall of the insert rod. The second slot is inserted with the third push block.

[0007] Furthermore, a fourth push block is vertically slidably arranged on the side of the connecting block near the steel pipe pile. The top of the fourth push block has an adapter hole that allows the third push block to pass through. The bottom of the workbench has a first slot. The protrusion slides and engages with the bottom of the fourth push block, causing the top of the fourth push block to be inserted into the first slot.

[0008] Furthermore, the third push block has a first threaded hole, the top of the connecting block has a second threaded hole, the second threaded hole and the first threaded hole are aligned and engaged, the top of the worktable has a connecting groove, one end of the connecting groove has a third threaded hole, the third threaded hole and the second threaded hole are aligned and engaged, and a connecting rod is detachably installed in the connecting groove.

[0009] Furthermore, both ends of the connecting rod are provided with through holes, which are aligned with the third threaded hole. Bolts are installed in the through holes, and the bolts are threadedly engaged with the third threaded hole, the second threaded hole, and the first threaded hole, respectively.

[0010] Furthermore, a second slider is fixedly provided at one end of the second push block, and a second spring is fixedly provided between the second slider and the connecting block.

[0011] Furthermore, a fourth slider is fixedly provided on one side of the fourth push block, and a fifth spring is fixedly provided between the fourth slider and the connecting block.

[0012] Furthermore, the bottom of the insertion rod is an arc-shaped chamfer, and the top of the end of the protrusion near the inside of the steel pipe pile is provided with a first inclined wedge surface, and the arc-shaped chamfer of the insertion rod slides in conjunction with the first inclined wedge surface.

[0013] Furthermore, the bottom of the second push block is provided with an arc-shaped chamfer at the end near the first push block, and the arc-shaped chamfer of the second push block slides in cooperation with the inclined surface of the first push block.

[0014] Furthermore, the bottom of the extrusion block near the second push block has an arc-shaped chamfer, and the arc-shaped chamfer of the extrusion block slides in cooperation with the inclined surface at the top of the second push block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] A third slider is fixedly mounted on the third push block, and a third spring is fixed between the third slider and the extrusion block. A second slot is opened on the side wall of the insertion rod, and the second slot is inserted into the third push block. The insertion rod at the bottom of the workbench is inserted into the corresponding steel pipe pile. As the insertion rod moves downwards, it drives the protrusion to move inwards towards the connecting block, thereby causing the protrusion to move the first push block. The first push block pushes the second push block upwards, and the second push block pushes the extrusion block towards the fourth push block, thus compressing the third spring. When the insertion rod is fully inserted into the steel pipe pile, the second slot and the third push block are aligned. At this point, under the action of the third spring's restoring force, the third slider drives the third push block into the second slot, fixing the insertion rod to the steel pipe pile and thus securing the workbench to the steel pipe pile. The third push block of this device is less likely to move within the second slot, resulting in a tighter connection between the steel pipe pile and the platform plate, preventing loosening and avoiding safety hazards.

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 9 As shown, the present invention discloses a deep-sea steep slope bare rock steel pipe pile platform, comprising multiple steel pipe piles 1, with multiple workbenches 21 installed on the top of the steel pipe piles 1, and the multiple workbenches 21 being spliced ​​together to form a construction plane. Insert rods 27 are fixedly welded to the four corners of the bottom of each workbench 21, and the insert rods 27 are inserted into and engaged with the corresponding steel pipe piles 1.

[0029] Two connecting blocks 2 are fixedly installed on the top of the steel pipe pile 1, and the two connecting blocks 2 are arranged perpendicularly to each other. A first push block 3 is horizontally slidably installed at the bottom of the connecting block 2. A first slider 4 is fixedly installed at the bottom of the first push block 3, and a first spring 5 is fixedly installed between the first slider 4 and the connecting block 2. A second push block 6 is vertically slidably installed on the side of the connecting block 2 away from the steel pipe pile 1. The end of the first push block 3 near the second push block 6 is inclined, and the inclined surface of the first push block 3 slides in cooperation with the bottom of the second push block 6. A second slider 7 is fixedly installed at one end of the second push block 6, and a second spring 8 is fixedly installed between the second slider 7 and the connecting block 2. The bottom of the second push block 6 near the end of the first push block 3 is provided with an arc-shaped chamfer. The arc-shaped chamfer of the second push block 6 slides in cooperation with the inclined surface of the first push block 3, which facilitates the first push block 3 to push the second push block 6 upward.

[0030] The other end of the first push block 3 penetrates through the steel pipe pile 1, and its top is provided with a protrusion 15. The insert rod 27 slides with the protrusion 15, driving the first push block 3 to move towards the second push block 6. The bottom of the insert rod 27 is an arc-shaped chamfer, and the top of the end of the protrusion 15 near the inside of the steel pipe pile 1 is provided with a first inclined wedge surface. The arc-shaped chamfer of the insert rod 27 slides with the first inclined wedge surface of the protrusion 15.

[0031] A third push block 10 is horizontally slidably installed at the top of the connecting block 2. A clearance groove 9 is provided at the top of the second push block 6 to avoid the third push block 10. Compression blocks 13 are slidably installed on both sides of the third push block 10. The top of the second push block 6 is sloped, and the sloped surface of the second push block 6 slides in engagement with the compression block 13. The bottom of the compression block 13, near the end of the second push block 6, has an arc-shaped chamfer. This arc-shaped chamfer of the compression block 13 slides in engagement with the sloped surface at the top of the second push block 6, facilitating the second push block 6 to push the compression block 13 towards the steel pipe pile 1.

[0032] Third sliders 11 are fixedly installed on both sides of the third push block 10, and third springs 12 are fixedly installed between the third sliders 11 and the corresponding pressing blocks 13. A second slot 29 is provided on the side wall of the insertion rod 27. The second slot 29 is inserted into the third push block 10. The lower contact surfaces of the third push block 10 and the second slot 29 are both inclined surfaces, and the third push block 10 is adapted to the second slot 29.

[0033] A fourth push block 16 is vertically slidably installed on the side of the connecting block 2 closest to the steel pipe pile 1. A fourth slider 18 is fixedly installed on one side of the fourth push block 16. A fifth spring 19 is fixedly installed between the fourth slider 18 and the connecting block 2. An adapter hole 17 is provided on the top of the fourth push block 16, allowing the third push block 10 to pass through. A first slot 28 is provided on the bottom of the worktable 21. The protrusion 15 slides and engages with the bottom of the fourth push block 16, causing the top of the fourth push block 16 to insert into the first slot 28. A second wedge surface is provided on the side of the protrusion 15 away from the steel pipe pile 1, and the second wedge surface of the protrusion 15 slides and engages with the bottom of the fourth push block 16.

[0034] The third push block 10 has a first threaded hole 14, and the top of the connecting block 2 has a second threaded hole 20. When one end of the third push block 10 is inserted into the second slot 29, the second threaded hole 20 aligns with the first threaded hole 14. The top of the workbench 21 has a connecting groove 22, and one end of the connecting groove 22 has a third threaded hole 23. When the insertion rod 27 is fully inserted into the steel pipe pile 1, the third threaded hole 23 aligns with the second threaded hole 20, and the connecting rod 24 can be detachably installed in the connecting groove 22.

[0035] Both ends of the connecting rod 24 are provided with through holes 25. When the connecting rod 24 is placed into the connecting groove 22, the through holes 25 are aligned with the corresponding third threaded holes 23. Bolts 26 are installed in the through holes 25, and the bolts 26 are threaded into the third threaded hole 23, the second threaded hole 20 and the first threaded hole 14 respectively.

[0036] The working principle of the deep-sea steep slope bare rock steel pipe pile platform provided by this invention is as follows:

[0037] In use, the steel pipe pile 1 is fixed on the bare rock, and the tops of multiple steel pipe piles 1 are on the same horizontal plane. Then, the insertion rod 27 at the bottom of the workbench 21 is inserted into the corresponding steel pipe pile 1. As the insertion rod 27 moves downward, the bottom of the insertion rod 27 slides with the protrusion 15, and drives the protrusion 15 to move into the interior of the connecting block 2. Thus, the protrusion 15 drives the first push block 3 to move towards the second push block 6. The inclined surface of the first push block 3 slides with the bottom of the second push block 6, and pushes the second push block 6 upward. The inclined surface at the top of the second push block 6 slides with the arc-shaped chamfer of the extrusion block 13, and pushes the extrusion block 13 towards the fourth push block 16.

[0038] Since the third push block 10 is not aligned with the adapter hole 17 on the fourth push block 16 in the initial state, the third push block 10 is blocked and cannot move. Therefore, the pressing block 13 cannot drive the third push block 10 to move through the third spring 12, thus compressing the third spring 12. When the protrusion 15 moves with the first push block 3, after the second wedge surface of the protrusion 15 contacts the bottom of the fourth push block 16, as the first push block 3 continues to move, under the sliding cooperation between the second wedge surface of the protrusion 15 and the bottom of the fourth push block 16, the fourth push block 16 moves upward, thereby aligning the adapter hole 17 on the fourth push block 16 with the third push block 10, and the resistance experienced by the third push block 10 disappears.

[0039] At this time, under the action of the reset force of the third spring 12, the third slider 11 is pushed to move towards the fourth push block 16, so that the third slider 11 drives the third push block 10 through the adapter hole 17 and into the second slot 29 on the insertion rod 27. Through the insertion and engagement of the third push block 10 and the insertion rod 27, the insertion rod 27 is fixedly connected to the steel pipe pile 1, thereby fixing the workbench 21 to the steel pipe pile 1.

[0040] At the same time, the fourth pusher 16 moves upward and inserts into the first slot 28 at the bottom of the workbench 21, further limiting the workbench 21 and improving the connection strength between the steel pipe pile 1 and the workbench 21.

[0041] Then, the connecting rod 24 is placed into the mating connecting grooves 22 on the two adjacent workbenches 21, and bolts 26 are used to pass through the through hole 25, the third threaded hole 23, the second threaded hole 20 and the first threaded hole 14 in sequence, and are threadedly connected to each threaded hole. While strengthening the connection between the workbenches 21, the third push block 10 is fixed to prevent the workbenches 21 from accidentally detaching from the steel pipe pile 1.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
