Description

Technical Field

[0001] The present invention relates to the field of water conservancy projects, and in particular to an anti-vibration gate structure and an installation method thereof, which can prevent a gate from vibrating under the impact of water flow when the gate is in a gate slot. Background Art

[0002] Gates are essential devices for opening and closing the water-passing openings of hydraulic structures. They can fully or partially open the openings according to the comprehensive needs of water conservancy and hydropower projects, controlling water levels and regulating flow. Planar gates offer advantages such as simple structure and reliable operation. However, compared to radial gates, planar gates have gate slots. In the design of metal gates for water conservancy projects, a gap within the gate slot is required for smooth gate lowering. However, this gap causes repeated vibrations due to the impact of the water flow when the gate is lowered into the gate slot, damaging the gate slot and the gate itself.

[0003] Currently, there are several methods for eliminating gaps within the gate slot to prevent vibration: First, the compression spring method involves installing compression springs on the gate side beams. This structure requires significant opening and closing force to lower and raise the gate. If the impact of the water flow is greater than the spring force, vibration prevention will fail. Second, the wedge block method involves installing a wide-top, narrow-bottom structure on the gate side beams. When the gate bottoms out, the wide-top, narrow-bottom structure fits perfectly within the gate slot. However, if this structure isn't accurately embedded, gaps will remain, making it difficult to prevent gate vibration. Summary of the Invention

[0044] The embodiment provides a gate structure that is anti-vibration, such as Figure 1 to Figure 1 2, it includes a gate opening hoist 1, a grab beam hoist 2, a gate body and a gate slot 8. The gate body includes a top gate 3, a middle gate 6 and a bottom gate 7. An anti-vibration component is provided between two adjacent gate sections. Two sets of anti-vibration components are provided between two adjacent gate sections. The two sets of anti-vibration components are symmetrically arranged at both ends of the gate body and the gate slot 8. The grab beam hoist 2 adopts an electromagnetic hooking beam, including an electromagnetic suction cup that automatically adsorbs the top of the top gate 3, the middle gate 6 and the bottom gate 7. The top gate 3, the middle gate 6 and the bottom gate 7 can be hoisted separately through electromagnetic control. The anti-vibration component includes an anti-vibration support 4 and an anti-vibration compression spring 5. The anti-vibration support 4 is installed at the bottom of the upper gate of two adjacent gate sections. The anti-vibration support 4 is an equilateral quadrilateral connecting rod mechanism, one of which is fixed at the bottom of the corresponding gate and is connected to the symmetrical hinge point through a rolling hinge 400. Elastic support blocks 401 are symmetrically provided at the other two hinge points of the anti-vibration support 4; the anti-vibration compression spring 5 is installed at the top of the lower gate of the two adjacent gate sections; the bottom gate 7, the middle gate 6 and the top gate 3 are hoisted into the gate groove 8 in turn by the gate opening hoist 1 and the grab beam hoist 2, and when the upper gate is hoisted to the top surface of the lower gate, the rolling hinge 400 of the anti-vibration support 4 at the bottom of the upper gate contacts the top of the anti-vibration compression spring 5, and the connecting rod structure of the anti-vibration support 4 is stretched open by the reaction force of the anti-vibration compression spring 5, causing the two elastic support blocks 401 on the anti-vibration support 4 to be pressed tightly against the inner walls of the two side walls of the gate groove 8. The unfolded length of the anti-vibration support 4 is greater than the width of the gate slot 8, but is as close to the width of the gate slot 8 as possible.

[0045] The embodiment provides a gate structure that is anti-vibration, such as Figure 10-2 、 Figure 11-2 and Figure 12-2 As shown in the drawings, the top surface of the middle gate 6 and the bottom section gate 7 is provided with an upwardly protruding gate limiting support block 9, and the bottom of the top section gate 3 and the middle gate 6 is provided with a gate limiting groove 10 corresponding to the limiting support block 9. When the middle gate 6 is located on the top surface of the bottom section gate 7, the limiting support block 9 on the top of the bottom section gate 7 is correspondingly embedded into the gate limiting groove 10 on the bottom surface of the middle gate 6. When the top section gate 3 is located on the top surface of the middle gate 6, the limiting support block 9 on the top of the middle gate 6 is correspondingly embedded into the gate limiting groove 10 on the bottom surface of the top section gate 3. The top section gate 3, the middle gate 6 and the bottom section gate 7 are spliced into a complete and sealed gate panel.

[0046] The embodiment provides a vibration-proof gate structure, as shown in Figure 11-1 and Figure 12-1 A compression spring cabin 11 is formed on the top surface of the bottom section gate 7 and the middle gate 6, the vibration-proof compression spring 5 is installed in the compression spring cabin 11 of the bottom section gate 7 and the middle gate 6, and a limiting cover plate 12 is arranged at the cavity opening of the compression spring cabin 11. Figure 9 As shown in the drawings, the vibration-proof compression spring 5 comprises a compression spring body 500 and a compression spring protection cover 502 fixed on the top of the compression spring body 500, and a compression spring protection cover limiting clamping plate 501 is symmetrically arranged at the bottom end of the compression spring protection cover 502. A sliding groove 13 matched with the compression spring protection cover 502 is formed on the limiting cover plate 12, and the bottom end of the compression spring body 500 is fixed on the bottom surface of the compression spring cabin 11. Figure 4-1 to Figure 4-3 Figure 6-1 to Figure 6-3 As shown in the drawings, in the stretched state of the vibration-proof compression spring 5, the compression spring protection cover 502 is stretched out of the limiting cover plate 12 through the sliding groove 13 and is clamped with the sliding groove 13 of the limiting cover plate 12 through the compression spring protection cover limiting clamping plate 501. In the compressed state of the vibration-proof compression spring 5, the compression spring protection cover 502 and the compression spring body 500 are all shrunk into the compression spring cabin 11. The edge beam of the top section gate 3 and the middle gate 6 is provided with a limiting shaft 14 of a supporting rod, which is convenient for the vibration-proof supporting rod to be seated on the vibration-proof compression spring 5, and the bottom edge of the middle gate is provided with a gate limiting surface, which is convenient for the accurate positioning of the lower section gate.

[0047] One of the embodiments, as shown in Figure 7 and Figure 8 ​As shown, the anti-vibration support 4 includes four anti-vibration support rods 402 hinged in sequence. The hinge point where the anti-vibration support 4 is connected to the gate body is connected via an anti-vibration support hinge shaft 403, and is installed on the corresponding gate body via the anti-vibration support hinge shaft. Anti-vibration support hinge sleeves are provided at both ends of the anti-vibration support hinge shaft 403. The anti-vibration support 4 is provided with an elastic support block 401. Two hinge points are connected via elastic support hinges 404, and elastic support seats 405 are provided at the two elastic support hinges 404. The elastic support block 401 is installed on the elastic support seat 405. The ends of the four anti-vibration support rods 402 in this embodiment are hinged in sequence, and the specific working process is as follows. Figure 4-1 to Figure 4-3 As shown, the anti-vibration support 4 becomes a diamond shape during the gate hoisting process. When the upper gate and the lower gate are about to approach each other, the rolling hinge 400 at the lower end of the diamond-shaped anti-vibration support 4 will contact the top surface of the compression spring protection cover 502 of the anti-vibration compression spring 5. In the process of continuing to lower, the four anti-vibration support rods 402 of the anti-vibration support 4 are squeezed and deformed, and the anti-vibration compression spring 5 will shrink into the compression spring cabin 11. At this time, the elastic support hinges 404 at both ends will slowly contact the inner wall of the gate slot 8 and clamp it.

[0048] Another embodiment, Figure 6-1 to Figure 6-3 The anti-vibration support 4 shown includes four anti-vibration support rods 402 connected by hinges, and the two hinge points of the elastic support block 401 are both arranged in the middle of the upper two anti-vibration support rods 402, and the elastic support block 401 is installed at the ends of the upper two anti-vibration support rods 402 through the elastic support seat 405; the working process of this embodiment is similar to the working process in the above embodiment.

[0049] The anti-vibration support 4 in the above two embodiments can be applied to gate slots of different widths, and can be adjusted according to the compression conditions of the anti-vibration support 4 to ensure that the two elastic support blocks 401 on the anti-vibration support 4 can be tightly attached to the slot wall of the gate slot 8, thereby ensuring the stability of the gate in the gate slot.

[0050] The installation method of the anti-vibration gate structure in the embodiment is characterized by the following specific steps:

[0051] S1. The lifting device 1 is accompanied by the grab beam lifting device 2. First, the bottom gate section 7 is lowered into the gate groove 8. The top of the bottom gate section 7 corresponds to the gate groove position. The compression spring compartment 11 is provided, and an anti-vibration compression spring 5 is installed in the compression spring compartment.

[0052] S2. The gate-opening hoist 1, along with the beam-grabbing hoist 2, then lowers the middle gate 6 into the gate slot 8. A vibration-isolating support 4, comprising a quadrilateral connecting rod structure, is installed at the lower portion of the middle gate 6. As the middle gate 6 is lowered until it contacts the top surface of the bottom gate 7, the connecting rod structure of the vibration-isolating support 4 is propped open by the reaction force of the vibration-isolating compression spring 5. The elastic support block 401 of the vibration-isolating support 4 reaches the side wall of the gate slot 8, completing the lifting of the middle gate 6.

[0053] S3 repeats step S2 to install the top gate section 3 in place. The installed top gate section 3, middle gate 6 and bottom gate section 7 form a complete gate body, and both ends are stably connected to the gate groove 8 through the anti-vibration support 4.

[0054] When the gate of the present invention is installed, during the process of lowering the gate, the anti-vibration support naturally falls down under the action of the gate's own weight and stretches on the anti-vibration compression spring until it reaches the gate slot.

[0055] The grab beam hoist in the present invention is an electromagnetic hook beam, which is controlled by electromagnetics to hoist the top gate, middle gate and bottom gate respectively. The anti-vibration force of the anti-vibration support 4 on the side wall of the gate slot 8 comes from the pressure of the anti-vibration compression spring 5.

[0056] In the present invention, the upper part of the top section gate 3 is a plane, which is convenient for automatic detachment from the electromagnetic hook and detachment beam. The lower part of the top section gate 3 is processed into a groove limiting surface, and only the anti-vibration support 4 is installed on the lower part of the side beam; the upper part of the middle gate 6 is processed into a protruding limiting support, and the anti-vibration compression spring 5 is installed on the upper part of the side beam. The lower part of the middle gate 6 is processed into a groove limiting surface, and only the anti-vibration support 4 is installed on the lower part of the side beam; the upper part of the bottom section gate 7 is processed into a protruding limiting support, and only the anti-vibration compression spring 5 is installed on the upper part of the side beam. The lower part of the bottom section gate structure is a plane for easy support with the gate bottom sill.

[0057] According to the relationship between the spring support force (Ft), the rod axial force (Fg), and the door slot vibration force (Fc): Ft=Fc×tg(ɑ), the closer the rod is to horizontal, the more obvious the spring support force amplification function is. For ease of installation, the rod is hinged in the middle without changing the spring support force.

[0058] The above is merely one embodiment of the present invention, and its description is relatively specific and detailed. However, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present invention, and such modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.

The anti-vibration gate structure according to claim 1 or 2, characterized in that: The anti-vibration support (4) comprises four anti-vibration support rods (402) hinged in sequence, the hinge point where the anti-vibration support (4) is connected to the gate body is connected via an anti-vibration support hinge shaft (403), and is mounted on the corresponding gate body via the anti-vibration support hinge shaft, and anti-vibration support hinge sleeves are respectively provided at both ends of the anti-vibration support hinge shaft (403); the anti-vibration support (4) is provided with an elastic support block (401), two hinge points of which are respectively connected via elastic support hinges (404), and elastic support seats (405) are respectively provided at the two elastic support hinges (404), and the elastic support block (401) is mounted on the elastic support seat (405).

7. The anti-vibration gate structure according to claim 1 or 2, characterized in that: The side beams of the top gate (3) and the middle gate (6) are mounted with support rod limiting shafts (14); the unfolded length of the anti-vibration support (4) is greater than the width of the gate slot (8).

8. The anti-vibration gate structure according to claim 1 or 2, characterized in that: The anti-vibration support (4) comprises four anti-vibration support rods (402) connected by hinges, two hinge points of the elastic support block (401) are both arranged in the middle of the two upper anti-vibration support rods (402), and the elastic support block (401) is installed at the ends of the two upper anti-vibration support rods (402) through the elastic support seat (405).

9. A method for installing the anti-vibration gate structure according to any one of claims 1 to 8, characterized in that: The specific steps are as follows: S1. The gate-opening hoist and the grab beam hoist first lower the bottom gate section into the gate slot. A compression spring compartment is located at the top of the bottom gate section, corresponding to the gate slot, and an anti-vibration compression spring is installed in the compartment. S2. The gate-opening hoist, along with the grab beam hoist, lowers the middle gate into the gate slot. A vibration-damping support with a quadrilateral connecting rod structure is installed at the lower portion of the middle gate. As the middle gate is lowered until it almost contacts the top surface of the bottom gate, the connecting rod structure is braced by the reaction force of the anti-vibration compression spring, allowing the elastic support block of the anti-vibration support to reach the side wall of the gate slot, completing the lifting of the middle gate. S3 repeats step S2 to install the top gate section in place. The installed top gate section, middle gate section and bottom gate section form a complete gate body, and both ends are stably connected to the gate slot through anti-vibration supports.

10. The method for installing a vibration-proof gate structure according to claim 9, characterized in that: The grab beam hoist is an electromagnetic hook and release beam, which is used to hoist the top gate, the middle gate and the bottom gate respectively through electromagnetic control.
