Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a modular steel cofferdam structure. Background Art

[0002] A cofferdam is a temporary retaining structure used during the construction of permanent water conservancy facilities. Its purpose is to prevent water and soil from entering the building site, allowing drainage, excavation, and construction within the cofferdam. It is typically used in hydraulic structures and, unless it is part of a formal structure, is typically dismantled after use.

[0003] The existing earth-rock cofferdams, sack cofferdams, etc. are simple to construct and low in cost, but they are not aesthetically pleasing and difficult to dismantle, making them unsuitable as temporary cofferdams. Steel plate cofferdams are mostly rectangular in shape, and other curved shapes require corresponding curved connecting plates, which is more troublesome. Therefore, in response to this situation, we propose a more convenient and practical steel cofferdam structure to meet the needs of use. Summary of the Invention

[0005] To achieve the above object, the present invention provides the following technical solutions:

The support mechanism includes a fixed plate, a fixed frame is fixedly connected to the center of the top of the fixed plate, a first screw is rotatably connected to one side of the fixed frame, a sliding block is slidably connected to the inner wall of the fixed frame, one end of the first screw is fixedly connected to a rotating handle, the outer wall of the first screw and the sliding block are threadedly connected, the top of the sliding block is rotatably connected to a support rod, one end of the support rod is rotatably connected to a connecting frame, one side of the connecting frame is fixedly connected to the support plate, the support plate and the fixed plate are rotatably connected, and a connecting mechanism and a telescopic mechanism are provided on one side of the support mechanism.

[0007] Furthermore, a sliding plate is slidably connected to each of the two sides of the fixed plate, and a plurality of equidistant through holes are opened in the center of the top of the sliding plate, and insertion rods are inserted into the through holes.

[0008] Furthermore, a lifting frame is fixedly connected to both sides of the support plate, a lifting block is slidably connected to the inner wall of one side of the lifting frame, a second screw is rotatably connected to the top of the lifting frame, the second screw and the lifting block are threadedly connected, and the lifting block and the mounting plate are connected.

[0009] Furthermore, the connecting mechanism includes a connecting plate, one side of which is fixedly connected to a clamping block, two sides of the connecting plate are provided with slots, the slots are plugged with connecting blocks, and one side of the connecting block is fixedly connected to a first plug-in plate.

[0010] Furthermore, one side of the first plug board is fixedly connected to a plurality of equidistant fixed blocks, one side of the fixed block is rotatably connected to a connecting rod, one side of the connecting plate is fixedly connected to a mounting block, one side of the mounting block is clamped with the mounting plate, and the top of the mounting block is fixedly connected to a positioning rod, which passes through the mounting plate.

[0011] Furthermore, the telescopic mechanism includes a clamping plate, a clamping groove is formed through the top of the clamping plate, the clamping groove and the clamping block are adapted to each other, and support blocks are fixedly connected to both sides of the clamping plate.

[0012] Furthermore, one side of the support block is rotatably connected to a first rotating plate, one side of the first rotating plate is rotatably connected to an adjustment plate, a bidirectional screw is threadedly connected to the center of the top of the adjustment plate, and a rotating ring is fixedly connected to the middle of one side of the bidirectional screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The modular steel cofferdam structure is provided with a supporting mechanism, a connecting mechanism and a telescopic mechanism. During use, the fixed plate is first placed on the ground, the sliding plate slides out along the groove to a suitable position, and the insertion rod is inserted into the ground to form an anchor. Then the operator rotates the handle to drive the first screw to rotate, so that the sliding block moves horizontally in the fixed frame, driving the support rod to move. Under the action of the connecting frame, the fitting angle between the support plate and the ground or structural surface is adjusted to form a triangular support structure to disperse the load. Then the motor on the top of the fixed frame drives the second screw to rotate to move the lifting block up and down, driving the mounting plate to adjust the height. The device can make the assembly shape diverse and easy to assemble, greatly shortening the on-site assembly time. It is highly practical and suitable for promotion.

[0016] At the same time, the telescopic mechanism controls the expansion angle of the first rotating plate and the second rotating plate by rotating the bidirectional screw, thereby realizing the telescopic plate extension and retraction to adapt to different cofferdam circumference requirements.
