Description

Technical Field

[0001] The invention relates to the technical field of metal structures of water conservancy and hydropower engineering, and in particular to a gate lateral and reverse support limit device and a use method thereof. Background Art

[0002] With the development of water conservancy projects, gates play a key role in water conservancy facilities. In practical applications, affected by the installation accuracy, a certain gap is generally reserved between the lateral and reverse supports of the gate and the embedded parts of the gate slot to ensure that the gate can be opened and closed freely.

[0003] However, for the open-top gates in long-term water-retaining work, especially the working gates of the outer river on large rivers and the working gates of the tide-blocking gates near the sea, they are significantly affected by the action of wind and waves. Due to the gap between the lateral and reverse supports and the gate slot, the gate will be in a vibrating state under the long-term action of wind and waves. This long-term vibration will cause fatigue damage to the lateral support structure, thus affecting the safe operation of the gate and adversely affecting the normal operation of the lock chamber building.

[0004] In order to solve this problem, a device is needed that can effectively limit the lateral and reverse displacement of the gate and prevent the vibration caused by wind and waves from damaging the supporting structure. Summary of the invention

[0005] The object of the present invention is to provide a lateral and reverse support limit device for a gate and a method of using the same, wherein a limit structure for limiting the freedom of a gate body is formed between a positioning slideway arranged on a gate slot pier and a slider on a gate body, so that the limit structures are squeezed against each other to achieve the purpose of limiting, thereby effectively limiting the lateral and reverse displacement of the gate, reducing vibrations caused by wind and waves, and improving the stability of the gate during operation.

[0006] The present invention is achieved through the following technical solutions:

[0007] A gate lateral and reverse support limit device, comprising:

[0008] A slider component, wherein the slider component is connected to the gate body;

[0009] A slideway component, wherein the slideway component is connected to the gate slot gate pier, and the slideway component and the slider component are squeezed against each other to form a limiting structure for limiting the freedom of the gate body;

[0010] Wherein, a slider is arranged on the slider component on one side facing the slideway component, and a positioning slideway matching the slider is arranged on the slideway component;

[0011] The slider is a special-shaped structure, the upper part of the slider is a rectangular parallelepiped structure, and the lower part of the slider is a cone structure.

[0012] In this solution, the limit device is arranged on the gate panel side or the beam grid side according to the water retaining direction of the gate, the slider component is connected to the gate body, the slideway component is connected to the gate slot gate pier, a slider with a special-shaped structure is arranged on the side of the slider component facing the slideway component, and a positioning slideway matching the slider is arranged on the slideway component. When the gate body is closed in place, the contact surfaces of the slider and the positioning slideway are squeezed against each other, thereby limiting the reverse support gap and lateral support gap of the gate, effectively solving the problem that the lateral support and reverse support of the gate are in a vibrating state for a long time due to the gap between the gate slot and the lateral support, resulting in fatigue damage of the supporting structure, affecting the safe operation of the gate, and causing adverse effects on the normal operation of the gate chamber building.

[0013] As a further technical solution to the limiting device, in order to ensure good contact between the slider and the contact surface of the positioning slide during the closing process of the gate, the length of the rectangular structure on the upper part of the slider accounts for 1 / 4 of the total length of the slider, and is used for lateral limitation between the slider and the gate groove during the opening and closing of the gate to avoid tilting and jamming when the gate is opened and closed. The cone structure at the lower part of the slider transitions evenly from coarse to fine from top to bottom, and the length of the cone structure accounts for 3 / 4 of the total length of the slider, and is used to cooperate with the positioning slide to ensure lateral and reverse limitation when the gate is closed to the bottom position.

[0014] As a further technical solution for the limiting device, in order to ensure seamless connection between the gate and the embedded parts in the gate groove when the gate is closed to block water and to ensure tight water stopping of the gate, the vertical distance h2 from the top edge line of the bottom edge of the cone structure to the top cross-section of the slider is greater than the thickness h3 of the bottom plate of the positioning slide, so as to avoid the problem of further damage to the lateral limiting structure caused by gate vibration caused by wind and waves.

[0015] As a further technical solution of the limiting device, in order to further improve the stability of the gate during operation, the vertical distance h1 from the lateral edge of the bottom edge of the cone structure to the side of the top cross-section of the slider is greater than the gap reserved from the gate support to the embedded part, so as to facilitate the slider to smoothly enter the groove of the positioning slide.

[0016] As a further technical solution of the limiting device, the slider component includes a pressure plate and a first corner connecting plate, the first corner connecting plate fixes the pressure plate to the gate body through connecting bolts, and the side of the first corner connecting plate is connected to the slider;

[0017] Among them, a plurality of adjustment plates are arranged between the pressure plate and the first corner connecting plate. By adjusting the number of the adjustment plates, the slider can be moved along the width direction of the gate groove pier, and the purpose of indirectly adjusting the reverse support gap of the gate body is achieved by adjusting the longitudinal position of the slider.

[0018] As a further technical solution of the limiting device, the slider component further includes a second corner connecting plate, the second corner connecting plate is connected to the side of the first corner connecting plate and is arranged opposite to the slideway component, and the angle between the first corner connecting plate and the second corner connecting plate is 90°;

[0019] Wherein, the sliding block is connected to the side of the second corner connecting plate opposite to the slideway component through connecting bolts;

[0020] Among them, an adjustment plate is also arranged between the slider and the second corner connecting plate. By adjusting the number of the adjustment plates, the slider can be moved in a direction perpendicular to the width of the gate slot pier, and the lateral support gap of the gate body can be indirectly adjusted by adjusting the lateral position of the slider.

[0021] As a further technical solution of the limiting device, a sealing rubber pad is arranged between the pressure plate and the gate body, and a sealing rubber pad drilling hole is opened on the sealing rubber pad. The diameter of the sealing rubber pad drilling hole is smaller than the diameter of the connecting bolt, thereby achieving tight water-stopping between the device and the gate body.

[0022] As a further technical solution of the limiting device, the slide component is connected to the gate groove pier through anchor bolts, the height of the slider is greater than the height of the positioning slide, and the height of the slider is greater than the sum of the installation heights of the connecting bolts and the anchor bolts. When the slider moves, interference between the raised part of the slide and the slider bolt head is avoided, and interference between the slider bolt head and the anchor bolt protruding from the bottom plate of the slide is avoided.

[0023] A method for using a gate lateral and reverse support limit device comprises the following steps:

[0024] S1. According to the water retaining direction of the gate, pre-install at least one set of the above-mentioned limit devices on the gate panel side or the beam grid side;

[0025] S2. Fix the slide member in the width direction of the gate slot pier through anchor bolts, and the positioning slide on the slide member faces outward;

[0026] S3. Connect the slider assembly to the gate body through connecting bolts, and the slider on the slider assembly faces the positioning slide. By adjusting the number of adjustment plates between the pressure plate and the first corner connecting plate and the number of adjustment plates between the slider and the second corner connecting plate, the position of the slider in space is changed so that the slider and the positioning slide form a complementary structure. When the gate body is closed in place, the contact surface between the slider and the positioning slide is in good contact.

[0027] When the gate body is closed, the top surface of the slider is flush with the top surface of the positioning slideway, and the side surfaces of the slider and the side surfaces of the positioning slideway remain vertical.

[0028] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0029] 1. The present invention can effectively limit the lateral and reverse displacement of the gate by means of the mutual extrusion and limiting of the positioning slideway and the slider, reduce the vibration caused by wind and waves, and improve the stability of the gate during operation.

[0030] 2. The present invention avoids excessive vibration of the gate by accurately limiting the slider with a special-shaped structure and the positioning slideway, thereby protecting the lateral support structure, extending its service life, ensuring the safe operation of the gate, and facilitating the normal operation of the gate chamber building.

[0031] 3. The present invention can accurately install and position the slider in the positioning slideway by adjusting the number of adjustment plates, thereby ensuring seamless connection between the gate and the embedded parts of the gate slot when the gate is closed. At the same time, a sealing rubber pad and a pressure plate are provided to further enhance the water-stopping sealing effect and effectively prevent water from leaking between the gate and the gate slot.

[0032] 4. The present invention also provides a method for using the limit device. The entire installation process is relatively simple. The slideway component is installed first, and then the slider component is installed. By adjusting the number of adjustment plates, good contact between the slider and the positioning slideway can be achieved. At the same time, the connection between the components is achieved by bolts, which facilitates installation operations and reduces installation difficulty and cost.

DETAILED DESCRIPTION

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0045] Affected by the installation accuracy, a certain gap is usually reserved between the lateral and reverse supports of the gate and the embedded parts of the gate slot, such as Figure 2 The reverse support gap 3 and the lateral support gap 4 shown in the figure are to ensure that the gate can be opened and closed freely. However, under the action of wind and waves, the exposed top gates in long-term water retaining work, especially the outer river working gates on large rivers and the working gates of the coastal tide-blocking gates, have long-term lateral supports and reverse supports in a vibrating state due to the gap between them and the gate groove, resulting in fatigue damage of the lateral support structure, affecting the safe operation of the gate and causing adverse effects on the normal operation of the lock chamber building. Therefore, in order to solve this problem, the present invention proposes the following technical solutions:

[0046] Example 1

[0047] This embodiment 1 provides a gate lateral and reverse support limit device, such as Figure 1 and Figure 2 As shown, it includes a slider component 1 and a slideway component 2. The slider component 1 is connected to the gate body 5 through connecting bolts, and the slideway component 2 is connected to the gate slot pier through anchor bolts. The slideway component 2 and the slider component 1 are squeezed against each other to form a limiting structure that limits the freedom of the gate body.

[0048] Among them, see Figure 3-Figure 6 and Figure 8As shown, the slider component 1 includes a first corner connecting plate 14, a second corner connecting plate 16 and a slider 17. The first corner connecting plate 14 is provided with two groups of corner connecting plate drilling holes 141. The gate body 5 is provided with threaded holes corresponding to the corner connecting plate drilling holes 141. The connecting bolts 18 are passed through the corner connecting plate drilling holes 141 to fix the first corner connecting plate 14 to the gate body 5. At the same time, the second corner connecting plate 16 is connected to the side of the first corner connecting plate 14 and is arranged opposite to the slideway component 2, and the first The angle between the corner connecting plate 14 and the second corner connecting plate 16 is 90°, and the slider 17 is connected to the side of the second corner connecting plate 16 opposite to the slide component 2. As for the connection method between the slider 17 and the second corner connecting plate 16, in this embodiment, two groups of corner connecting plate drilling holes 161 are set on the second corner connecting plate 16, and corresponding seat plate holes 171 are set on the slider 17. The connecting bolts 18 are passed through the corner connecting plate drilling holes 161 and the seat plate holes 171 to lock the slider 17 and the second corner connecting plate 16.

[0049] Among them, see Figure 4-Figure 7 As shown, the above-mentioned slide component 2 is integrally cast, and its base plate is a rectangular structure with two groups of positioning holes 221 opened around it. The anchor bolts 22 are installed and positioned in the width direction of the gate slot and gate pier through the positioning holes 221. A positioning slide 21 is connected to the middle of the seat plate. When the gate is closed, the positioning slide 21 and the slider 17 are squeezed against each other to achieve the purpose of limiting the freedom of the gate body.

[0050] The positioning slideway 21 and the slider 17 are matched and squeezed with each other to form a limiting structure. Therefore, in order to make the contact surface of the slider 17 and the positioning slideway 21 have good contact during the closing process of the gate, in this structure, the slider 17 is a special-shaped structure. Specifically, Figure 5 As shown, the upper portion of the slider 17 is a rectangular structure with inverted arc corners, and the length of the rectangular structure accounts for 1 / 4 of the total length of the slider. The lower portion of the slider 17 is a conical structure, and the conical structure transitions evenly from thick to thin from top to bottom, and the length of the conical structure accounts for 3 / 4 of the total length of the slider 17. Similarly, the upper portion of the positioning slide 21 is a rectangular structure with inverted arc corners, and the length of the rectangular structure accounts for 1 / 4 of the total length of the slider. The lower portion of the positioning slide 21 is an L-shaped structure as a whole, presenting a uniform transition structure from thick on top to thin on the bottom, and the length accounts for 3 / 4 of the total length of the positioning slide 21.

[0051] Example 2

[0052] In order to make the gate seamlessly connected with the gate slot embedded parts when closing the gate to block water and ensure the gate is tightly sealed, this embodiment 2 provides another gate lateral and reverse support limit device based on the technical solution of embodiment 1, such as Figure 1-Figure 8As shown, in the present embodiment, the slider component 1 includes a pressure plate 12, on which a pressure plate drilling hole 121 corresponding to the corner connecting plate drilling hole 141 is opened, and a plurality of adjustment plates 13 are arranged between the pressure plate 12 and the first corner connecting plate 14, wherein the adjustment plate 13 is provided with an adjustment plate drilling hole 131 corresponding to the corner connecting plate drilling hole 141, and the connecting bolt 18 passes through the corner connecting plate drilling hole 141, the adjustment plate drilling hole 131 and the pressure plate drilling hole 121 and is threadedly connected with the threaded hole on the gate body 5. In actual application, by adjusting the number of the adjustment plates 13, the slider 17 moves along the width direction of the gate slot pier, and by adjusting the longitudinal position of the slider 17, the purpose of indirectly adjusting the reverse support gap 3 of the gate body 5 is achieved.

[0053] At the same time, an adjustment plate 13 is also arranged between the slider 17 and the second corner connecting plate 16. By adjusting the number of the adjustment plates 13, the slider 17 can move along the width direction of the vertical gate groove pier. By adjusting the lateral position of the slider 17, the purpose of indirectly adjusting the lateral support gap 4 of the gate body 5 can be achieved.

[0054] In order to improve the water-tightness between the device and the gate body 5, a sealing rubber pad 11 is arranged between the pressure plate 12 of this embodiment and the gate body 5. The sealing rubber pad 11 can adopt a seal made of rubber or rubber-plastic material as needed, and a sealing rubber pad drilling hole 111 is opened on the sealing rubber pad 11. The diameter of the sealing rubber pad drilling hole 111 is smaller than the diameter of the connecting bolt 18, thereby preventing water from leaking from the connection between the sealing rubber pad 11 and the connecting bolt 18.

[0055] In this embodiment, in order to improve the reliability of the slider component 1 , a rib 15 is provided between the corner connecting plate 16 and the corner connecting plate 14 .

[0056] Example 3

[0057] In order to further ensure that the gate is watertight, this embodiment 3 provides another gate lateral and reverse support limit device in the technical solution of embodiment 1 or embodiment 2, such as Figure 1-Figure 8 As shown, the height of the slider 17 is greater than the height of the positioning slide 21, and the height of the slider 17 is greater than the sum of the installation heights of the connecting bolts 18 and the anchor bolts 22. At the same time, the vertical distance h2 from the top edge line of the bottom edge of the above-mentioned cone structure to the top cross-section of the slider 17 is greater than the thickness h3 of the bottom plate of the positioning slide 21, thereby avoiding the problem of further damage to the lateral limiting structure caused by the vibration of the gate caused by wind and waves.

[0058] Furthermore, a vertical distance h1 from the lateral edge line of the bottom edge of the cone structure to the side surface of the top cross section of the slider 17 is greater than the gap reserved from the gate support to the embedded part, that is, the reverse support gap 3.

[0060] This embodiment 4 provides a method for using a gate lateral and reverse support limit device, comprising the following steps:

[0061] S1. According to the direction of the gate retaining water, at least one set of limiting devices in any one of Examples 1-3 is pre-installed on both sides of the gate panel or the beam grid side;

[0062] S2. The slide member 2 is fixed to the width direction of the gate slot pier by the anchor bolts 22, and the positioning slide 21 on the slide member 2 faces outward;

[0063] S3. Connect the slider component 1 to the gate body 5 through the connecting bolts 18, and the slider 17 on the slider component 1 faces the positioning slide 22. By adjusting the number of adjustment plates 13 between the pressure plate 12 and the first corner connecting plate 14 and the number of adjustment plates 13 between the slider 17 and the second corner connecting plate 16, the position of the slider 17 in space is changed so that the slider 17 and the positioning slide 21 form a complementary structure. When the gate body 5 is closed, the top surface of the slider 17 is flush with the top surface of the positioning slide 21, and the side surface of the slider 17 and the side surface of the positioning slide 21 remain vertical; when the gate body 5 is closed, the contact surface of the slider 17 and the positioning slide 22 is in good contact.
