Description

Technical Field

[0001] This invention relates to the field of sheet pile support technology, specifically a sheet pile support device that is easy to disassemble and its usage method. Background Technology

[0002] Sheet pile support is made of hot-rolled steel with interlocking or clamping jaws. Connecting these sheet piles in an orderly manner forms a sheet pile wall. When laying natural gas pipelines, a trench needs to be dug first, and then sheet piles are used to support the side walls of the trench.

[0003] In cold regions, such as Siberia, when sheet piles are used for support, the sheet piles freeze together with the soil on the sidewalls of the ditch. Due to the adhesion of the frozen material, it is difficult to remove the sheet piles, which reduces the removal efficiency, prolongs the construction period, and makes it inconvenient for users.

[0004] To address the aforementioned issues, an improved, easily disassembled sheet pile support device and its usage method are now designed. Summary of the Invention

[0005] The purpose of this invention is to provide a steel sheet pile support device that is easy to disassemble and its usage method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A steel sheet pile support device that is easy to disassemble includes a fixed plate, a dismantling mechanism, and a connecting mechanism. Several fixed frames are vertically installed on one side wall of the fixed plate, and two adjacent fixed frames are fixed together. Several movable plates are arranged vertically inside the fixed frames. Several movable rods are horizontally installed on the side wall of the movable plates near the fixed plate. The end of the movable rod away from the movable plate passes through the fixed plate and is installed with a support frame for supporting the side wall of the ditch. The side walls of adjacent support frames are tightly fitted together.

[0008] The dismantling mechanism is located inside the fixed frame and is used to move the support frame away from the ditch, dismantling the support frame piece by piece, thereby improving the dismantling efficiency of the fixed plate.

[0009] The connecting mechanism is set on the fixed frame on both sides of the fixed plate and is used to splice the two fixed plates to facilitate the support of the ditch.

[0010] As a further aspect of the present invention: the dismantling mechanism includes threaded columns corresponding to the movable plates one by one. One end of each threaded column is horizontally mounted on the side wall of the movable plate away from the fixed plate. An internal threaded rotating cylinder is rotatably connected to the side wall of the threaded column via a thread. A rotating seat is rotatably connected to the end of the internal threaded rotating cylinder away from the movable plate. The rotating seat is mounted on the inner wall of the fixed frame. A support plate for supporting the internal threaded rotating cylinder is rotatably connected to the side wall of the internal threaded rotating cylinder near the movable plate. The side wall of the support plate is mounted on the inner wall of the fixed frame. A toothed ring for driving the internal threaded rotating cylinder to rotate is installed on the side wall of the internal threaded rotating cylinder between the support plate and the rotating seat. A drive assembly for driving several toothed rings one by one is provided inside the fixed frame.

[0011] As a further embodiment of the present invention: the driving assembly includes a rack that cooperates with the gear ring. When the rack moves, it can mesh with the gear ring. Limiting slide rods are vertically installed on both sides of the rack. The upper end of the limiting slide rod passes through the top of the fixed frame and is equipped with a moving frame that facilitates the movement of the limiting slide rod by the operator using instruments. A limiting frame for limiting the limiting slide rod is slidably connected to the side wall of the limiting slide rod. The upper and lower ends of the limiting frame are respectively installed at the top and bottom of the fixed frame. A locking assembly for fixing the gear ring when it is not driven is provided on the inner wall of the fixed frame near the gear ring.

[0012] As a further embodiment of the present invention: the locking assembly includes elastic telescopic rods corresponding one-to-one with the toothed rings. The elastic telescopic rods are horizontally installed on the inner wall of the fixed frame near the toothed rings. The output end of the elastic telescopic rods is equipped with trapezoidal rubber blocks for locking the toothed rings. The upper and lower ends of the rack are both equipped with protrusions that cooperate with the inclined surfaces of the trapezoidal rubber blocks.

[0013] As a further embodiment of the present invention: the connecting mechanism includes a fixing rod, and connecting rods are horizontally installed on the two opposite side walls of the fixing rod. Connecting slots that cooperate with the connecting rods are installed on the fixing frames on both sides of the fixing plate. The connecting slots are located at the end of the fixing frame away from the fixing plate.

[0014] As a further aspect of the present invention: rubber pads are installed on the side walls of the support frame to facilitate tight fitting between the support frames.

[0015] As a further aspect of the present invention, the movable rod is provided with reinforcing ribs inside to improve the structural strength of the movable rod.

[0016] As a further aspect of the present invention: a stainless steel sheet is installed on the inclined surface of the trapezoidal rubber block to facilitate the sliding of the protrusion.

[0017] As a further aspect of the present invention: the inner wall of the rotating seat is equipped with balls to facilitate the rotation of the internally threaded rotating cylinder.

[0018] A method for using a steel sheet pile support device that is easy to disassemble includes the following steps:

[0019] Step 1: When removing the fixing plate, depending on the degree of freezing, multiple moving frames can be connected in series using a support rod, so that multiple moving frames can move together. The staff moves the moving frames upward using the equipment. The moving frames drive the limiting slide rod to move, the limiting slide rod drives the rack to move, the rack drives the protrusion to move, the protrusion pushes the trapezoidal rubber block away from the toothed ring, and compresses the elastic telescopic rod, so that the rack and the toothed ring mesh with each other.

[0020] Step 2: Then the rack drives the gear ring to rotate. Under the action of the thread, the gear ring drives the threaded column to move away from the fixed plate. The threaded column drives the moving plate to move. The moving plate drives the moving rod to move. The moving rod drives the support frame to move towards the fixed plate, thereby freeing the support frame from the frozen soil and realizing the rapid removal of the fixed plate.

[0021] Step 3: Then push the fixing rod upward, the fixing rod drives the connecting rod to move, so that the connecting rod disengages from the connecting slot, realizing the separation of the two adjacent fixing plates.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Compared with the prior art, this invention changes the large-area contact of the existing fixing plate to the small-area contact of several support frames. In cold and frozen conditions, the fixing plate can be removed by removing the support frames one by one. At the same time, since the contact area of ​​the support frames is small, the freezing adhesion is also small, making it easier to remove the fixing plate and effectively improving the removal efficiency of the fixing plate in cold and frozen environments.

[0024] At the same time, by engaging the racks one by one with the toothed rings, the force on the moving frame is reduced, allowing the force to be concentrated on dismantling a single support frame.

[0025] Depending on the degree of freezing, multiple movable frames can be connected in series using a single support rod, allowing them to move together and further improving the efficiency of support frame removal.

[0026] During use, the toothed ring is supported and locked by trapezoidal rubber blocks. When the fixed plate is moved, the internal thread rotating cylinder is prevented from rotating, so that the support frame can be on the same plane and the device can be used normally.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-5 In this embodiment of the invention, a steel sheet pile support device that is easy to disassemble includes a fixed plate 1, a dismantling mechanism and a connecting mechanism. Several fixed frames 4 are vertically installed on one side wall of the fixed plate 1, and two adjacent fixed frames 4 are fixed together. Several movable plates 16 are arranged vertically inside the fixed frame 4. Several movable rods 2 are horizontally installed on the side wall of the movable plate 16 near the fixed plate 1. The end of the movable rod 2 away from the movable plate 16 passes through the fixed plate 1 and is installed with a support frame 3 for supporting the side wall of the ditch. The side walls of adjacent support frames 3 are tightly fitted together.

[0035] The dismantling mechanism is located inside the fixed frame 4 and is used to move the support frame 3 away from the ditch, dismantle the support frame 3 piece by piece, and improve the dismantling efficiency of the fixed plate 1.

[0036] The connecting mechanism is set on the fixing frames 4 on both sides of the fixing plate 1, and is used to splice the two fixing plates 1 to facilitate the support of the ditch.

[0037] The dismantling mechanism includes threaded posts 15 corresponding to the movable plate 16. One end of each threaded post 15 is horizontally mounted on the side wall of the movable plate 16 away from the fixed plate 1. The side wall of the threaded post 15 is rotatably connected to an internal threaded rotating cylinder 11 via a thread. The end of the internal threaded rotating cylinder 11 away from the movable plate 16 is rotatably connected to a rotating seat 13. The rotating seat 13 is mounted on the inner wall of the fixed frame 4. A support plate 10 for supporting the internal threaded rotating cylinder 11 is rotatably connected to the side wall of the internal threaded rotating cylinder 11 near the movable plate 16. The side wall of the support plate 10 is mounted on the inner wall of the fixed frame 4. A toothed ring 9 for driving the internal threaded rotating cylinder 11 to rotate is installed on the side wall of the internal threaded rotating cylinder 11 between the support plate 10 and the rotating seat 13. The interior of the fixed frame 4 is provided with a drive assembly for driving several toothed rings 9 one by one.

[0038] The driving assembly includes a rack 14 that works with the gear ring 9. When the rack 14 moves, it can mesh with the gear ring 9. Limiting slide rods 5 are vertically installed on both sides of the rack 14. The upper end of the limiting slide rod 5 passes through the top of the fixed frame 4 and is equipped with a moving frame 6 to facilitate the movement of the limiting slide rod 5 by the operator using instruments. A limiting frame 12 for limiting the limiting slide rod 5 is slidably connected to the side wall of the limiting slide rod 5. The upper and lower ends of the limiting frame 12 are respectively installed at the top and bottom of the fixed frame 4. A locking assembly is provided on the inner wall of the fixed frame 4 near the gear ring 9 to fix the gear ring 9 when it is not driven.

[0039] Compared with existing technologies, the large-area contact of the existing fixing plate 1 is replaced by the small-area contact of several support frames 3. In cold and frozen conditions, the fixing plate 1 can be removed by removing the support frames 3 one by one. At the same time, since the contact area of ​​the support frames 3 is small, the freezing adhesion is also small, making it easier to remove, effectively improving the removal efficiency of the fixing plate 1 in cold and frozen environments.

[0040] At the same time, by making the racks 14 engage with the toothed rings 9 one by one, the force on the moving frame 6 is reduced, and the force can be concentrated to dismantle one support frame 3.

[0041] Depending on the degree of freezing, multiple movable frames 6 can be connected in series using a support rod, allowing multiple movable frames 6 to move together, further improving the efficiency of dismantling the support frame 3.

[0042] The locking assembly includes elastic telescopic rods 8 that correspond one-to-one with the toothed rings 9. The elastic telescopic rods 8 are horizontally installed on the inner wall of the fixing frame 4 near the toothed rings 9. The output end of the elastic telescopic rods 8 is equipped with trapezoidal rubber blocks 18 for locking the toothed rings 9. The upper and lower ends of the rack 14 are equipped with protrusions 17 that cooperate with the inclined surfaces of the trapezoidal rubber blocks 18.

[0043] Compared with the existing technology, by supporting and locking the toothed ring 9 with trapezoidal rubber blocks 18, the internal thread rotating cylinder 11 can be prevented from rotating when the fixed plate 1 is moved, so that the support frame 3 can be on the same plane and the device can be used normally.

[0044] The connecting mechanism includes a fixing rod 19, on which connecting rods 20 are horizontally installed on two opposite side walls. Connecting slots 7 that cooperate with the connecting rods 20 are installed on the fixing frames 4 on both sides of the fixing plate 1. The connecting slots 7 are located at the end of the fixing frame 4 away from the fixing plate 1.

[0045] Working principle of an easily disassembled sheet pile support device:

[0046] When removing the fixed plate 1, depending on the degree of freezing, multiple movable frames 6 can be connected in series using a support rod, so that multiple movable frames 6 can move together. The workers move the movable frames 6 upwards using the equipment. The movable frames 6 drive the limiting slide rod 5 to move. The limiting slide rod 5 drives the rack 14 to move. The rack 14 drives the protrusion 17 to move. The protrusion 17 pushes the trapezoidal rubber block 18 away from the toothed ring 9 and compresses the elastic telescopic rod 8, so that the rack 14 and the toothed ring 9 mesh with each other.

[0047] Then, the rack 14 drives the gear ring 9 to rotate. Under the action of the thread, the gear ring 9 drives the threaded column 15 to move away from the fixed plate 1. The threaded column 15 drives the moving plate 16 to move. The moving plate 16 drives the moving rod 2 to move. The moving rod 2 drives the support frame 3 to move towards the fixed plate 1, thereby freeing the support frame 3 from the frozen soil and realizing the rapid removal of the fixed plate 1.

[0048] Then push the fixing rod 19 upward, the fixing rod 19 drives the connecting rod 20 to move, so that the connecting rod 20 disengages from the connecting slot 7, thereby separating the two adjacent fixing plates 1.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
