Description

Technical Field

[0001] The present application relates to the technical field of connection structures, and in particular to a steel pipe pile cofferdam tubular lock buckle. Background Art

[0002] During the construction of a bridge, the piers may be fixed in an environment with deep water, fast currents and complex geological conditions. In order to enable the piers to reach a certain strength, construction workers usually build a cofferdam structure before construction to maintain a relatively stable environment for the piers, thereby providing a foundation for subsequent related construction.

[0003] In the related art, the cofferdam structure includes a large number of steel pipes, and the construction workers need to connect the steel pipes. When connecting, the construction workers usually use steel pipe clamps to connect the steel pipes, and then fix the steel pipe clamps to the installation rods to complete the positioning of the steel pipes.

[0004] With regard to the above-mentioned related technologies, different diameters of steel pipes of cofferdam structures are different, and construction workers need to prepare different numbers of steel pipe clamps, which is inconvenient for construction workers to install and seriously reduces the work efficiency of construction workers. Utility Model Content

[0005] In order to limit the position of steel pipes of different diameters and improve the work convenience of construction workers, the present application provides a steel pipe pile cofferdam pipe-type lock.

[0006] This application provides a steel pipe pile cofferdam pipe lock buckle, which adopts the following technical solution:

[0007] The steel pipe pile cofferdam tubular lock comprises a supporting device and an abutment device, wherein the supporting device comprises a vertical rod and a horizontal rod, wherein the horizontal rod slides along the vertical rod, wherein the horizontal rod is provided with a fixed block, wherein the fixed block is provided with two fixed tubes, wherein the fixed tubes are rotatably connected with the fixed blocks, wherein the inner cavity of the fixed tubes is provided with a moving rod, wherein the moving rod slides along the fixed tubes; wherein two abutment devices are provided at the end of the moving rod, wherein the abutment device comprises a telescopic rod and a supporting plate, wherein the telescopic rod is rotatably connected with the moving rod, wherein the supporting plate is rotatably connected with the telescopic rod, wherein a plurality of abutment components are provided along the length direction of the supporting plate, wherein the abutment component comprises an elastic rod and an abutment plate, wherein one end of the elastic rod is fixedly connected with the support plate, and the other end is rotatably connected with the abutment plate.

[0008] By adopting the above technical solution, when the construction workers fix the steel pipe, the vertical rod provides support for the installation of the horizontal rod. Then the construction workers adjust the number of horizontal rods and the position of the horizontal rods relative to the vertical rods. The construction workers adjust the angle of the fixed pipe according to the diameter of the steel pipe, and adjust the length of the mobile rod relative to the fixed pipe, so that the two mobile rods are located on both sides of the steel pipe. Then the construction workers adjust the angle of the telescopic rod relative to the mobile rod and the length of the telescopic rod so that the telescopic rod can be closer to the steel pipe. The support plate provides installation support for the abutment assembly. Then the abutment plate fits the side wall of the steel pipe. At the same time, the elastic rod is squeezed and contracted, so that the abutment plate can better fit the side wall of the steel pipe, completing the multi-directional limitation of the steel pipe. The construction workers can complete the limitation of steel pipes of different diameters through a set of equipment, avoiding the preparation of a large number of steel pipe clamps, and improving the convenience of the construction workers' work.

[0009] Optionally, a contact pad is provided at one end of the abutment plate away from the elastic rod, and the contact pad is fixedly connected to the abutment plate.

[0010] By adopting the above technical solution, the contact pad contacts the steel pipe, and the contact pad is deformed by the abutment plate and the steel pipe, which can effectively increase the effective contact area between the abutment plate and the steel pipe and improve the limiting effect on the steel pipe.

[0011] Optionally, the fixed tube is provided with an avoidance groove, the movable rod is provided with a mounting block, the mounting block is fixedly connected to the movable rod, and the avoidance groove is used to accommodate the mounting block, and the telescopic rod is rotatably connected to the mounting block.

[0012] By adopting the above technical solution, the setting of the avoidance groove provides installation support for the sliding of the mounting block, and the mounting block provides support for the installation of the telescopic rod, so that even if the movable rod is completely located in the inner cavity of the fixed tube, the telescopic rod will not be restricted by the side wall of the fixed tube, thereby improving the overall adaptability of the device.

[0013] Optionally, a locking assembly is provided at the telescopic rod, and the locking assembly includes a ratchet and a pawl, the ratchet is fixedly connected to the telescopic rod and rotatably connected to the mounting block, the pawl is rotatably connected to the mounting block, and the ratchet is engaged.

[0014] By adopting the above technical solution, when the construction workers rotate the telescopic rod, the ratchet and the pawl engage, thereby preventing the telescopic rod from being squeezed and rotating in the opposite direction when contacting the steel pipe, thereby reducing the limiting effect on the steel pipe.

[0015] Optionally, the moving rod is equipped with a support rod, one end of the support rod is fixedly connected to the moving rod, and the other end of the support rod is rotatably connected to the fixed block.

[0016] By adopting the above technical solution, the setting of the support rod can provide stable support for the moving rod when the moving rod is extended from the fixed tube, and further provide stable support for the abutment device, thereby ensuring the limiting and stabilizing effect on the steel pipe.

[0017] Optionally, a connecting piece is provided at the end of the movable rod away from the fixed tube, and the connecting piece is fixedly connected to the movable rod.

[0018] By adopting the above technical solution, a connecting piece is provided at the end of the movable rod. When construction workers limit the steel pipe, they can connect the connecting piece to a driving structure such as a crane, and the driving structure drives the movable rod to slide along the fixed rod, thereby avoiding the construction workers manually driving the movable rod to slide along the fixed pipe, thereby improving the working speed of the construction workers.

[0019] Optionally, each of the cross bars is provided with a connecting device, which also includes a connecting rod and a connecting plate, one end of the connecting rod is rotatably connected to the connecting plate, and the other end is rotatably connected to the cross bar, and a contact plate and a bolt are provided in the inner cavity of the connecting plate, the bolt is threadedly connected to the connecting plate, and the end of the bolt is rotatably connected to the contact plate.

[0020] By adopting the above technical solution, the length of the connecting rod can be adjusted so that the connecting plate is as close to the external fixed structure as possible. The connecting plate is then sleeved on the fixed structure, and the bolt is rotated to make the contact plate as close to and lock the fixed structure as possible, thereby improving the stability of the cross bar and thus improving the overall stability of the device.

[0021] Optionally, a mounting plate is provided at the bottom of the vertical rod, and a plurality of anchor screws are evenly distributed around the mounting plate.

[0022] By adopting the above technical solution, the mounting plate can increase the contact area between the vertical rod and the ground. The mounting plate is fixed to the ground by abutment bolts, thereby improving the connection stability between the mounting plate and the ground, and ultimately improving the connection stability between the vertical rod and the ground, and ultimately providing stable support for the entire device.
