Description

Technical Field

[0001] This utility model belongs to the technical field of gate equipment, and in particular relates to a triangular arc-shaped gate leaf structure. Background Technology

[0002] The structural optimization and mechanical performance of ship lock triangular gates are important research directions. Early studies used spatial finite element analysis to simulate the stress distribution, deformation characteristics, and safety stability of the gates, ensuring structural reliability. In terms of manufacturing processes, high-precision CNC machining equipment is used to improve steel cutting accuracy, ensuring the dimensional accuracy of each component of the gate. Regarding welding processes, automated welding equipment is employed, which not only improves welding efficiency but also ensures stable weld quality and reduces welding defects caused by human factors.

[0003] Modular installation technology was adopted, breaking down the arc-shaped triangular gate into multiple modules. These modules were pre-assembled and tested in the factory before being transported to the site for rapid assembly, significantly shortening the on-site installation period and improving the reliability of the installation quality. The arc-shaped gate has a unique structure; due to the inclined arc surface, the bottom of the gate needs to withstand greater pressure. Furthermore, the arc-shaped gate uses a flip-type opening and closing structure, resulting in a stronger impact between the lower side of the gate and the gate slot during the closing phase. This uneven stress at the bottom of the gate can easily lead to deformation of the bottom housing structure and weld detachment. Utility Model Content

[0004] The purpose of this utility model is to provide a triangular arc-shaped gate leaf structure to solve the problem that the bottom of the arc-shaped triangular gate is easily deformed and damaged due to the strong impact force during the opening and closing process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A triangular arc-shaped gate leaf structure includes an arc-shaped gate leaf. Both sides of the inner arc side of the gate leaf are fixed with a triangular frame. The triangular frame has two crossbeams. One end of the two crossbeams is fixed to the same hinge seat, and the other end is fixed to the upper and lower sides of the gate leaf respectively.

[0007] The door leaf has a box-like structure, and a buffer device is installed at the bottom of the door leaf;

[0008] The buffer device includes a contact plate, and a buffer pad is installed between the contact plate and the bottom of the door leaf.

[0009] Furthermore, hydraulic devices are installed on both sides of the gate leaf for flip-type opening and closing. One end of the hydraulic device is hinged to the side of the river mouth embankment, and the other end is hinged to the inner arc side of the gate leaf.

[0010] Furthermore, the door leaf includes an arc-shaped plate on the outer arc side and two horizontal plates on the inner arc side. The two horizontal plates are integrally connected by a connecting part. The upper side of the arc-shaped plate is aligned and welded to the upper side of the horizontal plate, and the lower side has a bottom plate. A transverse rib plate and a longitudinal rib plate are provided in the interlayer between the arc-shaped plate and the horizontal plate. After the transverse and longitudinal rib plates are spliced, the interlayer is divided into multiple uniform squares to form a box structure. A reinforcing rib is also fixed on the inner arc side of the arc-shaped plate.

[0011] Furthermore, the touch plate is hinged to the base plate, and the touch plate has a hinge sleeve corresponding to the outer arc side of the door leaf. The bottom of the door leaf has a hinge shaft for the hinge sleeve to fit into. The touch plate has folded plates on both sides to cover the bottom of the lower edge plate. The folded plates have arc-shaped limiting holes, and limiting rods are fixed to the corresponding edge plates to cooperate with the limiting holes.

[0012] The buffer pad is wrapped around the free side of the contact plate. The buffer pad has a U-shaped cross-section, and a water seepage hole is provided at the position corresponding to the hinge side of the contact plate.

[0013] This utility model has the following beneficial effects: In order to ensure the service life of the bottom of the door leaf box structure, a contact plate is used to replace the bottom of the door leaf in contact with the sealing groove. The contact plate is a detachable installation structure. If it is deformed due to its own weight impact during the opening and closing process, the contact plate can be replaced to avoid deformation of the bottom of the door leaf or cracking of the weld, which would lead to greater irreparable losses.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-2 As shown: A triangular arc-shaped gate leaf structure includes an arc-shaped gate leaf 1. Triangular frames 2 are fixed to both sides of the inner arc side of the gate leaf 1. Each triangular frame 2 has two crossbeams, one end of which is fixed to the same hinge seat 21, and the other ends are fixed to the upper and lower sides of the gate leaf 1 respectively. The two crossbeams and the gate leaf directly form a stable, approximately triangular structure. A concrete embankment structure is poured at the location corresponding to the river mouth, reserving space for the river mouth. This gate leaf structure is then installed, and a hinge shaft is installed at the location corresponding to the hinge seat at the river mouth. This shaft engages with the hinge hole of the hinge seat, and the gate leaf is flipped through an opening and closing device to achieve the opening and closing of the gate.

[0022] Gate leaf 1 is a box structure with a buffer device installed at the bottom. The gate leaf is made by welding multiple steel plates to ensure tight welds. The steel plate surface is coated with corrosion-resistant paint to prevent rusting in water. As a box structure, the gate leaf has sufficient internal space to ensure structural stability, similar to a buoyancy gate. The gate can be opened and closed by reducing the power of the opening and closing device.

[0023] The buffer device includes a contact plate 4, and a buffer pad 5 is installed between the contact plate 4 and the bottom of the door leaf 1.

[0024] To ensure the service life of the bottom of the door leaf box structure, a contact plate is used instead of the bottom of the door leaf to contact the sealing groove. The contact plate is a detachable installation structure. If it is deformed by its own weight during opening and closing, the contact plate can be replaced to avoid deformation of the bottom of the door leaf or cracking of the weld, which could lead to greater irreparable losses.

[0025] Hydraulic devices 3 are installed on both sides of the gate leaf 1 for tilting opening and closing. One end of the hydraulic device 3 is hinged to the side of the river mouth embankment, and the other end is hinged to the inner arc side of the gate leaf 1. The hydraulic device includes a hydraulic cylinder and a hydraulic rod, which are installed with hinges at both ends. The gate leaf can be tilted during the contraction or release phase of the hydraulic device.

[0026] like Figure 2As shown: The door leaf 1 includes an arc-shaped plate 11 on the outer arc side and two horizontal plates 12 on the inner arc side. The two horizontal plates 12 are integrally connected by a connecting part. The upper sides of the arc-shaped plate 11 and the horizontal plates 12 are aligned and welded together, and the lower sides are welded to both sides of the same base plate 13. A transverse rib plate 14 and a longitudinal rib plate 14 are provided in the interlayer between the arc-shaped plate 11 and the horizontal plates 12. After the transverse and longitudinal rib plates 14 are spliced, the interlayer is divided into multiple uniform squares to form a box structure. A reinforcing rib is also fixed on the inner arc side of the arc-shaped plate 11. The base plate increases the contact area between the door leaf and the reserved sealing groove of the dam, reduces local stress, and improves structural stability.

[0027] like Figures 3-4 As shown: the touch plate 4 is hinged to the base plate 13. The touch plate 4 has a hinge sleeve 41 on the outer arc side of the door leaf 1, and the bottom of the door leaf 1 has a hinge shaft 6 for the hinge sleeve 41 to fit on. This hinged installation of the touch plate and the bottom plate of the door leaf provides sufficient buffer space. The touch plate 4 has folding plates 42 on both sides to cover the bottom of the lower edge plate 14. The folding plates 42 have arc-shaped limiting holes 43, and limiting rods 61 are fixed to the edge plate 14 to cooperate with the limiting holes 43. During the opening and closing of the door leaf, the flipping position of the limiting touch plate creates a linkage effect.

[0028] A buffer pad 5 is wrapped around the free side of the contact plate. The buffer pad 5 has a U-shaped cross-section, and a seepage hole 44 is provided at the position corresponding to the hinge side of the contact plate 4. The upper side of the buffer pad is used to contact the base plate to prevent rigid contact, and the lower side of the buffer pad is used to contact the sealing groove to improve the sealing performance after closing. The seepage hole can drain the water that accumulates between the contact plate and the base plate when the gate is opened.

[0029] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
