Description

Technical Field

[0001] This utility model relates to the field of steel gates in water conservancy and hydropower projects, and more specifically, to a self-locking system applied to stacked beam gates. Background Technology

[0002] The stacked beam gate, also known as the stacked beam valve, is a water-blocking structure that uses multiple individual gate plates, which are placed horizontally into the gate slot one by one and stacked to form a flat surface. The stacked beam gate has a simple structure, light weight, low lifting force, and is easy to transport.

[0003] Traditional stacked beam gates are mainly installed and dismantled during maintenance using simple lifting lugs and hooks. When the water level is high, the installation and dismantling become more difficult. Relying solely on gravity often results in inadequate sealing, leading to risks of gate jumping and overall gate swaying. This not only results in poor performance but also increases time and labor costs. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a self-locking system for stacked beam gates, which can achieve self-locking through the self-locking shaft in the self-locking mechanism, thereby avoiding the problems of jumping between stacked beam gates and excessive shaking amplitude of stacked beam gates.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A self-locking system for stacked beam gates includes a self-locking mechanism and a self-locking shaft. The self-locking mechanism includes a base plate with two shaped plates mounted on its upper end. A rotating hole and a groove are formed in the center of each shaped plate. Positioning holes are formed at both ends of the groove in the center of each shaped plate. A main shaft is mounted in the center of the two rotating holes. Two claw hooks are mounted on the outer side of the main shaft. Two limiting pins are mounted between the two shaped plates, limiting the claw hooks. A winding groove is mounted in the center of the main shaft, and hexagonal wrench latches are formed at both ends of the main shaft. The claw hook includes a locking block, a locking groove and a round hole in the middle of the locking block, a stop block on one side of the locking block, a first binding hole at the end of the stop block away from the locking block, a second binding hole in the middle of the locking block located on the side of the locking groove, and an inclined surface at the upper end of the locking block. A steel cable is connected between the first binding hole and the winding groove, and a spring is connected between the second binding hole and the positioning hole closest to the opening side of the slot. This allows for self-locking via the self-locking shaft within the self-locking mechanism, preventing jumping between stacked beam gates and excessive swaying of the stacked beam gates.

[0007] Furthermore, the shaping plate has through holes at both ends of the groove in the middle, and a limit stop pin is installed in the middle of the through hole so that the limit stop pin can be fixed to limit the claw hook.

[0008] Furthermore, pressure plates are installed at both ends of the self-locking shaft, and the self-locking shaft matches the slot, enabling the self-locking shaft to be quickly installed at the bottom of the stacked beam gate.

[0009] Furthermore, the self-locking shaft is installed at the bottom of the stacked beam gate via a pressure plate, and the self-locking mechanism is installed at the top of the stacked beam gate via a base plate, so that the self-locking shaft at the bottom of the upper stacked beam gate can engage with the self-locking mechanism at the top of the lower stacked beam gate.

[0010] Furthermore, the self-locking mechanism and the self-locking shaft are respectively corresponding, and the outer end of the main shaft is provided with retaining rings on both sides of the claw hook, so that the self-locking shaft can be locked into the middle of the self-locking structure, and the claw hook is not easy to deviate.

[0011] Furthermore, a hoisting groove is provided on one side of the shaping plate to facilitate the hoisting of the stacked beam gate.

[0012] Compared with existing technologies, the advantages of this utility model are: By leveraging the self-locking effect of the self-locking shaft and the self-locking mechanism, combined with the spring's resetting action on the claw hook, the upper and lower stacked beam gates can be firmly locked, solving the problem of jumping between stacked beam gates and significantly reducing their sway amplitude, ensuring that the gate body remains stable during operation.

[0013] The mechanism uses components such as springs, steel cables, and detachable self-locking shafts to achieve automatic locking and free unlocking functions, which can meet the installation requirements under different working conditions. At the same time, it can also lift the entire underwater stacked beam gate out by hoisting one of the stacked beam gates into the gate slot from the ground outside the river channel, without the need for underwater operations.

[0014] The double-claw hook design further enhances the stability of the structure, ensuring the locking effect of the system even if one spring fails. While maintaining the self-locking effect, it can also be manually unlocked by disassembling the self-locking shaft and rotating the internal hexagonal jaws. Attached Figure Description

[0020] Example 1 This embodiment illustrates the structure of the device and its beneficial effects: Please see Figure 1-8 A self-locking system for stacked beam gates includes a self-locking mechanism and a self-locking shaft 14. The self-locking mechanism includes a base plate 1, with two shaped plates 2 mounted on the upper end of the base plate 1. A rotating hole 3 and a groove 4 are formed in the middle of the shaped plate 2. Positioning holes 6 are formed at both ends of the groove 4 in the middle of the shaped plate 2. A main shaft 7 is mounted in the middle of the two rotating holes 3. Two claw hooks 8 are mounted on the outer side of the main shaft 7. Two limiting pins 9 are installed between the two shaped plates 2, which can limit the claw hooks 8. A winding groove 10 is installed in the middle of the main shaft 7, and hexagonal wrench latches 11 are formed at both ends of the main shaft 7. The claw hook 8 includes a locking block 801, a locking groove 802 and a round hole 803 in the middle of the locking block 801, a stop block 804 on one side of the locking block 801, a first binding hole 805 at the end of the stop block 804 away from the locking block 801, a second binding hole 806 in the middle of the locking block 801 located on the side of the locking groove 802, and an inclined surface 807 at the upper end of the locking block 801. A steel cable 12 is connected between the first binding hole 805 and the winding groove 10, and a spring 13 is connected between the second binding hole 806 and the positioning hole 6 closest to the opening side of the slot 802.

[0021] Please see Figure 2-4 The shaping plate 2 has through holes 5 at both ends of the groove 4 in the middle. A limit stop pin 9 is installed in the middle of the through hole 5, so that the limit stop pin 9 can be fixed to limit the claw hook 8. The self-locking shaft 14 has pressure plates installed at both ends, and the self-locking shaft 14 matches the slot 802, so that the self-locking shaft 14 can be quickly installed at the bottom of the stacked beam gate. The self-locking shaft 14 is installed at the bottom of the stacked beam gate through the pressure plates, and the self-locking mechanism is installed at the top of the stacked beam gate through the base plate 1, so that the self-locking shaft 14 located at the bottom of the upper stacked beam gate can be engaged with the self-locking mechanism located at the top of the lower stacked beam gate.

[0022] Please see Figure 2-6 The self-locking mechanism and the self-locking shaft 14 are respectively corresponding, and the outer end of the main shaft 7 is provided with retaining rings on both sides of the claw hook 8, so that the self-locking shaft 14 can be locked into the middle of the self-locking structure and the claw hook 8 is not easy to deviate. The shaping plate 2 is provided with a lifting groove 15 on one side to facilitate the lifting work of the stacked beam gate.

[0023] Example 2 This embodiment illustrates the working principle of the device: Install the self-locking mechanism on the upper end of the stacked beam gate, install the self-locking shaft 14 on the lower end of the stacked beam gate through the pressure plate, hoist the stacked beam gate into the waterway gate slot through the hoisting slot 15, and then hoist another stacked beam gate into the waterway gate slot. The self-locking shaft 14 at the bottom of the upper stacked beam gate contacts the self-locking structure at the top of the lower stacked beam gate. The self-locking shaft 14 contacts the inclined plane 807 and applies a force perpendicular to the inclined plane 807, causing the claw hook 8 to rotate outward along the main shaft 7. Then, the self-locking shaft 14 continues to be inserted downward into the slot 802. After the self-locking shaft 14 enters the slot 802, the claw hook 8 is only subjected to the tension of the spring 13. The claw hook 8 is reset under the action of the spring 13. The two claw hooks 8 rotate inward along the main shaft 7, and the self-locking shaft 14 enters the bottom of the slot 802. The two claw hooks 8 self-lock and limit the self-locking shaft 14. At this time, the two stacked beam gates complete the self-locking. All the self-locking stacked beam gates can be hoisted out as a whole by hoisting the self-locking structure hoisting slot 15 located at the top of the uppermost stacked beam gate, without the need for underwater work; When it is necessary to open the self-locking stacked beam gates, the main shaft 7 can be rotated by turning the hexagonal wrench latch 11. This causes the cable winding groove 10 to rotate the claw hooks 8 along the outer side of the main shaft 7 by rotating the cable winding 12, so that the self-locking shaft 14 is no longer locked and limited by the two claw hooks 8. This achieves self-locking of the self-locking shaft 14 in the self-locking mechanism, avoiding the problems of jumping between the stacked beam gates and excessive shaking of the stacked beam gates.

[0024] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
