Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular relates to a concrete pouring and sealing device for gate piers. Background Technology

[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing hydraulic engineering projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.

[0003] In water conservancy projects, gate piers are an important component of sluice gates. During the concrete pouring process of the gate piers, sealing devices are needed to close the reserved holes or other areas that require sealing to ensure the quality of the concrete pouring and the integrity of the structure.

[0004] Traditional gate pier concrete pouring and sealing devices have fixed dimensions, making them unsuitable for gate piers with pre-drilled holes of different specifications and sizes. They also suffer from poor versatility and are cumbersome to install and dismantle, consuming significant time and manpower and reducing construction efficiency. Therefore, we provide a gate pier concrete pouring and sealing device to address these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gate pier concrete pouring sealing device. Through the cooperation of fixed components and linkage components, it solves the problems of fixed size, poor applicability, and cumbersome disassembly and assembly of existing sealing devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a concrete pouring sealing device for gate piers, comprising a sealing assembly. A fixing assembly is fixedly connected to the inner cavity of the sealing assembly, and a linkage assembly is fixedly connected to the axis of the sealing assembly. The sealing assembly includes a support column, the surface of which has an installation groove. A receiving groove is formed on one side of the inner cavity of the installation groove. A connecting rod is movably connected to the inner cavity of the receiving groove via the fixing assembly. A threaded tube is threadedly connected to the top of the connecting rod, and a sealing plate is fixedly connected to the top of the threaded tube. A pin hole is formed on the surface of the connecting rod. The fixing assembly includes a pin tube inserted into the inner cavity of a pin hole. A lead screw is threaded into the inner cavity of the pin tube. One end of the lead screw is fixedly connected to the inner wall of a receiving groove via a bearing. A bevel gear one is fixedly connected to the surface of the lead screw. A bevel gear two meshes with the surface of the bevel gear one. A drive shaft is fixedly connected to the surface of the bevel gear two. A bevel gear three is fixedly connected to the other end of the drive shaft. The linkage assembly includes a rotating shaft fixedly connected to the axis of a support column via a bearing. A bevel gear four is fixedly connected to the surface of the rotating shaft. The bevel gear four meshes with the bevel gear three.

[0008] The present invention is further configured such that a limiting groove is formed in the inner wall of the receiving groove, a limiting block is slidably connected to the inner cavity of the limiting groove, and the other side of the limiting block is fixedly connected to the surface of the pin tube. The sliding cooperation between the limiting groove and the limiting block ensures that the pin tube moves accurately along the axial direction, prevents locking failure caused by radial offset, and improves the structural stability of the fixing component.

[0009] The present invention is further configured such that the sealing plate is arc-shaped, and six sealing plates are closed to form a circular tube. The sealing plates can be replaced as needed to form a complete circular tube. By replacing the sealing plates with different arcs, the device can be adapted to non-circular holes, thus expanding its applicable range.

[0010] The present invention is further configured such that the inner wall of the support column has a circular hole through which the transmission shaft passes, the transmission shaft is fixedly connected to the inner wall of the circular hole by a bearing, and the transmission shaft is fixed to the circular hole of the support column by a deep groove ball bearing, thereby reducing transmission resistance, ensuring the meshing accuracy of the bevel gear set, and ensuring the synchronous linkage effect of multiple fixed components.

[0011] The present invention is further configured such that both ends of the rotating shaft are fixedly connected to a handle, and the surface of the handle is provided with anti-slip texture. The anti-slip texture on the surface of the handle provides a comfortable grip and can effectively prevent slippage even in a wet environment, thereby improving the ease of operation.

[0012] The present invention is further configured such that the surface of the sealing plate is coated with a Teflon coating, and a release agent is applied to its surface before pouring concrete. The Teflon coating has extremely low surface energy, and when used in conjunction with the release agent, it significantly reduces damage from manual knocking during demolding, ensuring the flatness of the gate pier surface.

[0013] The present invention is further configured such that the connecting rods are arranged in groups of three and distributed at equal distances from each other. The three groups of connecting rods form a uniform support structure, ensuring that the sealing plate is subjected to balanced force during concrete pouring and avoiding leakage caused by local deformation.

[0014] The present invention is further configured such that the fixing components are arranged in three groups at the front and rear, and each group has six components, which are distributed at equal intervals around the axis of the support column. The three groups of fixing components are distributed at equal intervals around the axis of the support column, and the radial symmetrical adjustment of the sealing plate is achieved through synchronous transmission.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model achieves adaptive adjustment of the sealing device's size through the coordinated design of linkage and fixing components. Rotating the handles at both ends of the rotating shaft drives the transmission shaft to rotate through the meshing transmission of bevel gear four and bevel gear three. This, in turn, causes bevel gear two to drive bevel gear one and the lead screw to rotate, controlling the insertion and removal state of the pin tube in the pin hole. When the pin tube is inserted into the pin hole, the connecting rod and the support column are fixed, and the six arc-shaped sealing plates close to form a circular tube, precisely fitting the reserved holes of the gate pier. This modular design eliminates the need to replace the entire device; only sealing plates of different sizes need to be replaced. Compared with traditional fixed-size sealing devices, this equipment significantly reduces the equipment idle cost caused by incompatible specifications, and is especially suitable for concrete pouring projects of various types of gate piers.

[0017] 2. This utility model adopts a fully mechanical transmission quick-locking scheme. Through the synchronous drive of the rotating shaft, three sets of circumferentially distributed fixing components are realized to achieve synchronous extension and retraction control of multiple sets of connecting rods. When installation is required, the handle is turned clockwise, and the screw drives the pin tube to insert into the pin hole of the connecting rod, fixing the sealing plate to the support column. When disassembling, the handle is turned counterclockwise, and the pin tube is disengaged from the pin hole, and the sealing plate can be quickly disassembled. The cooperation design of the limit groove and the limit block ensures stable movement of the pin tube and avoids jamming. Compared with the traditional bolt connection method, it saves a lot of manual operation time. In addition, the surface of the sealing plate is sprayed with Teflon coating and coated with release agent, which effectively reduces concrete adhesion, further improves demolding efficiency, and ensures the molding quality and appearance accuracy of the gate pier concrete.
