Description

Technical Field

[0001] This utility model relates to an arc-shaped gate, specifically an arc-shaped gate with a quick-switching suspension point, belonging to the field of hydraulic steel structure technology. Background Technology

[0002] Arc-shaped steel gates are a type of gate structure. Traditional arc-shaped steel gates typically consist of hinges, arms, gate leaves, and hoists, and usually operate in two modes: water blocking and upward-tilting maintenance. In practical applications, existing arc-shaped steel gates have been found to have the following main problems: Firstly, the unreasonable structural design of the arc-shaped gate can affect river navigation and aesthetics; secondly, when adjustments are needed, switching the hydraulic cylinder lifting points requires manual removal of the lifting head pin and adjustment of the hoist angle using engineering equipment, which is difficult and risky. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an arc gate with a reasonable structural design, reliable operation, and the ability to quickly switch the lifting points when switching the working mode of the arc gate.

[0004] To solve the above-mentioned technical problems, the present invention provides a quick-switching arc-shaped gate, comprising a hydraulic cylinder mounted via a hinge, two support arms mounted via pivots, a gate leaf mounted at the front end of the support arms and capable of reciprocating between a pair of guide embedded parts in a concrete wall, and a locking device for locking the gate leaf. At least one support arm has a constant connection point at its rear end for the normal operation of the gate leaf. In the normal state of the gate leaf, the telescopic end of the hydraulic cylinder is hinged to the constant connection point and can be driven by the hydraulic cylinder to rotate the gate leaf around the pivot to a water-blocking state and a navigation / cleaning state. The front end of the support arm with the constant connection point also has a maintenance support point near the side of the gate leaf. When the gate leaf needs maintenance, the telescopic end of the hydraulic cylinder can be hinged to the maintenance support point. At least one support arm has two locking holes near the upper and lower sides of the gate leaf, respectively. The locking device can selectively engage with the two locking holes to lock the support arm.

[0005] An angle adjustment device is provided below the tail of the hydraulic cylinder for adjusting the pitch angle of the hydraulic cylinder. The pitch angle of the hydraulic cylinder is adjusted by the angle adjustment device to switch the lifting point.

[0006] The angle adjustment device includes a hinge seat located below the hydraulic cylinder, an adjustment rod hinged on the hinge seat, and an adjustment seat with an adjustment hole mounted on the hydraulic cylinder. The adjustment seat is provided with an adjustment block for cooperating with the adjustment rod and an adjustment handle for cooperating with the adjustment block. The adjustment rod extends into the adjustment hole of the adjustment seat and can be adjusted by the adjustment handle to move the adjustment rod within the adjustment hole.

[0007] The guide embedded parts are pre-embedded in the side wall of the concrete wall and are adapted to the running trajectory of the gate leaf. The gate leaf is provided with a slider that cooperates with the guide embedded parts to limit the running deviation on both sides of the gate.

[0008] The gate leaf has a surface water-stop structure on its arc-shaped surface, and there is an arc-shaped casting bottom sill between the concrete walls on both sides that matches the arc-shaped surface of the gate leaf. The arc-shaped casting bottom sill is provided with a bottom water-stop embedded part that matches the surface water-stop structure.

[0009] The surface water-stopping structure includes a top water-stopping component disposed on the upper side of the arc-shaped surface of the gate leaf and a bottom water-stopping component disposed on the lower side of the arc-shaped surface of the gate leaf.

[0010] The concrete wall is provided with a side water-stop embedded part located next to the guide embedded part, and the side of the gate leaf is provided with a side water-stop part that cooperates with the side water-stop embedded part.

[0011] The side waterstop, top waterstop, and bottom waterstop are all sluice gate waterstop sealing components.

[0012] The gate leaf is provided with an upper scraping device for scraping off debris accumulated at the bottom of the gate, located next to the top water stop, and a lower scraping device for scraping off debris accumulated at the bottom of the gate, located next to the bottom water stop.

[0013] The advantages of this utility model are:

[0014] (1) In addition to the constant connection support point at the rear end of the support arm for the normal operation of the gate leaf, there is also a maintenance support point near the side of the gate leaf on the front end side of the support arm and a locking device for locking the gate leaf. Thus, when the gate leaf needs maintenance, the extension end of the hydraulic cylinder can be hinged to the maintenance support point, which can realize the quick switching between working and maintenance states. Its structural design is very simple and ingenious, and it is very convenient to operate and use.

[0015] (2) By setting an angle adjustment device for adjusting the pitch angle of the cylinder below the tail of the cylinder, during the switching process, on the one hand, the cylinder can be locked by the locking device and then adjusted, which is easy to operate and has low risk. On the other hand, during the switching process, the pitch angle of the cylinder can be finely adjusted by the angle adjustment device so that the extension end of the cylinder can be smoothly hinged to the maintenance support point, which further reduces the difficulty and risk of operation.

[0016] (3) By installing the upper and lower scraping devices, the waterway can be cleaned, ensuring the reliability of the gate leaf operation. Attached Figure Description

[0027] The arc-shaped gate with quick switching of lifting points of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] As shown in the figure, the arc-shaped gate with quick-switching lifting points of this utility model includes a pair of support arms 4 respectively installed between the concrete walls on both sides of the river channel via pivots 3, a hydraulic cylinder 2 installed via hinges 1, and a pair of guide components 5 pre-embedded in the concrete walls. A gate leaf 6, capable of reciprocating between the pair of guide components 5, is installed between the front ends of the two support arms 4. A locking device 7 for locking the gate leaf is also provided on the concrete wall. Figure 1 , Figure 2As can be seen, a support arm 4 is installed on the inner wall of the concrete wall on both sides of the river channel via a pivot 3. The gate leaf 6 is installed at the front end of each support arm. An arc-shaped guide component 5 is pre-embedded in each of the two concrete walls. This means the guide components 5 are embedded within the sidewalls of the concrete walls and are adapted to the running trajectory of the gate leaf 6. A slider 16 is provided on the gate leaf 6 to cooperate with the guide components and limit the running deviation on both sides of the gate. The synchronous movement of the two support arms causes the gate leaf 6 to swing back and forth. In this embodiment, a hydraulic cylinder 2 is installed on one side of one of the concrete walls via a hinge 1, and a constant connection fulcrum 8 is provided at the rear end of the support arm 4 corresponding to the hydraulic cylinder on that side to enable the gate leaf to work normally. In the normal state of the gate leaf, the extension end (i.e., the piston rod) of the hydraulic cylinder 2 is hinged to the constant connection fulcrum 8 via a hinge seat 26 and can be driven by the hydraulic cylinder 2 to rotate the gate leaf around the pivot 3 to the water-blocking state and the navigation / cleaning state. Figure 4 The diagram shows the water-blocking state. As can be seen from the figure, at this time, the telescopic end of the hydraulic cylinder 2 is in the retracted state, and the gate leaf is in a vertical state to achieve water blocking. Figure 5 The diagram illustrates the navigation or cleaning state. As shown, in this state, the telescopic end of the hydraulic cylinder 2 is extended, and the gate leaf 6 swings from a vertical position to a horizontal position, allowing navigation. This process also includes cleaning. A maintenance support point 9 is located near the gate leaf on one side of the front end of the support arm 4 driven by the hydraulic cylinder 2. When the gate leaf 6 requires maintenance, the telescopic end of the hydraulic cylinder can be hinged to this maintenance support point 9. The support arm 4 has two locking holes, one near the upper side and the other near the lower side of the gate leaf. The locking device 7 can selectively engage with the two locking holes 26 to lock the support arm. Figure 6 The maintenance status is shown. When changing the lifting point, the arm is first locked by the locking device 7 and the locking hole 17. At this time, the extension and retraction end of the oil cylinder is in the retracted state.

[0029] Furthermore, an angle adjustment device 10 for adjusting the pitch angle of the hydraulic cylinder can be provided below the tail of the hydraulic cylinder 2. The pitch angle of the hydraulic cylinder can be adjusted by the angle adjustment device 10 so that the telescopic end of the hydraulic cylinder can be hinged to the maintenance fulcrum 9. Figure 9As can be seen, in this embodiment, the angle adjustment device 10 includes a hinge seat 11 located below the hydraulic cylinder 2, an adjustment rod 12 hinged on the hinge seat, and an adjustment seat 13 with an adjustment hole mounted on the hydraulic cylinder 2. The adjustment seat 13 is provided with an adjustment block 14 for cooperating with the adjustment rod and an adjustment handle 15 for cooperating with the adjustment block. The adjustment rod 12 extends into the adjustment hole of the adjustment seat and can move within the adjustment hole by adjusting the adjustment block through the adjustment handle 15. The angle adjustment device 10 is mainly used to fine-tune the pitch angle of the hydraulic cylinder when changing the lifting point so as to easily and accurately change the lifting point. In fact, the angle adjustment device 10 can be removed after maintenance is completed. Figure 5 As shown.

[0030] Furthermore, between the bottoms of the two concrete walls, there is an arc-shaped cast-in-place sill 18 that matches the arc-shaped surface of the gate leaf 6. The arc-shaped cast-in-place sill 18 is provided with a bottom water-stop embedded part 19 that matches the surface water-stop structure. The surface water-stop structure includes a top water-stop 20 provided on the upper side of the arc-shaped surface of the gate leaf 6 and a bottom water-stop 21 provided on the lower side of the arc-shaped surface of the gate leaf 6. A side water-stop embedded part 22 is provided on the concrete wall next to the guide embedded part 5. A side water-stop 23 that matches the side water-stop embedded part 22 is provided on the side of the gate leaf 6. In addition, in this embodiment, the side water-stop 23, the top water-stop 20 and the bottom water-stop 21 are all standard sluice gate water-stop sealing parts.

[0031] Furthermore, an upper scraping device 24 for scraping away debris accumulated at the bottom of the gate can be provided on the arc-shaped surface of the gate leaf 6, located beside the top water-stopping member 20, and a lower scraping device 25 for scraping away debris accumulated at the bottom of the gate, located beside the bottom water-stopping member 21.

[0032] Its working principle is as follows:

[0033] Water blocking state: When the piston rod of hydraulic cylinder 2 retracts, it drives the support arm 4 to rotate via the pivot, driving the gate leaf 6 to rotate. When the gate leaf 6 rotates to a vertical position (e.g. Figure 3 and Figure 4 When the gate is in the water-blocking state, the locking device 7 is locked; at this time, the side water-stop structure and the bottom water-stop structure on the gate leaf 6 form a seal with the side water-stop embedded part and the bottom water-stop embedded part respectively; during the rotation, the slider 16 on the gate leaf 6 and the guide embedded part 5 limit the running deviation on both sides of the gate.

[0034] Navigation / Soil Cleaning Status: When the piston rod of hydraulic cylinder 2 extends, it drives the support arm 4 to rotate via the pivot, thereby driving the gate leaf 6 to rotate. When the gate leaf 6 rotates to the bottom of the gate (e.g. Figure 5() is in navigation / cleaning state; during rotation, the upper and lower scraping devices on the arc-shaped surface of the gate leaf 6 scrape away the debris accumulated at the bottom of the gate; when the gate leaf 6 is in this state for a long time, the top water stop 20, the bottom water stop 21, the upper scraping device 24 and the lower scraping device 25 play the role of preventing debris from accumulating at the bottom of the gate; during rotation, the slider 16 on the gate leaf 6 and the guide embedded part 5 limit the running deviation on both sides of the gate.

[0035] Maintenance status: When the piston rod of cylinder 2 retracts, it drives the support arm 4 to rotate via the pivot, which in turn drives the gate leaf 6 to rotate. When the gate leaf 6 rotates to the top of the gate (e.g. Figure 6 When the gate is in maintenance mode, the locking device 7 is locked; during rotation, the slider 16 on the gate leaf 6 and the guide embedded part 5 limit the running deviation on both sides of the gate.

[0036] It should be noted that when switching between the gate's navigation and maintenance modes, the lifting point switching work must be carried out after the water-blocking state locking device 7 is locked.

[0037] The process of switching the suspension point is as follows:

[0038] Switching between suspension points, such as Figure 6 As shown, when switching the lifting point, remove the bolts from the support arm 4 and the hinge seat 26. Adjust the cylinder to a suitable angle using the manual or automatic angle adjustment device 10 at the tail of the cylinder. Then, operate the hydraulic equipment to extend the cylinder piston rod, so that the lifting head and the hinge seat reach the corresponding positions. Then, fine-tune the angle again to align the bolt holes and tighten them again. After the maintenance is completed, reverse the operation to return to the navigation working mode.

[0039] Furthermore, the above embodiments are descriptions of a single hydraulic cylinder. In practice, a hydraulic cylinder that cooperates with a corresponding support arm can also be set on both sides of the concrete wall to form a double hydraulic cylinder drive structure. This utility model does not limit this.

[0040] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
