[0033] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] like Figures 1 to 10 As shown, this utility model provides an automatic gate locking device, including a lifting rod 1, a sliding sleeve 2, a support 3, and a support member 4.
[0035] The lifting rod 1 is installed in two locations: one is on the detachment beam 8, and the other is on each of the remaining door leaf 9 except for the bottommost door leaf 9. The lifting rod 1 is fixedly installed on the detachment beam 8 and slidably installed on the door leaf 9. Two or more lifting rods 1 are provided on both the detachment beam 8 and the door leaf 9, symmetrically distributed. The specific number of lifting rods 1 is determined according to the lifting load. Near the bottom of the lifting rod 1, a locking groove 5 is provided, forming a circumferential ring. The upper and lower ends of the locking groove 5 form a larger diameter upper boss 6 and a lower boss 7, respectively.
[0036] The sliding sleeve 2 serves two purposes: firstly, it allows for the sliding installation of the hanger rod 1 on the door leaf 9; secondly, it restricts the downward movement of the upper hanger rod 1. The sliding sleeve 2 is fixedly installed on each door leaf 9 and forms a sliding installation with the corresponding hanger rod 1. The hanger rod 1 can move up and down within the sliding sleeve 2.
[0037] Support 3 is fixedly installed on each door leaf 9, and support 3 and hanger 1 are configured in a 2:1 ratio, that is, two supports 3 are symmetrically distributed on both sides of the axis of each hanger 1.
[0038] The support member 4 is pivotally mounted on the support 3. The support member 4 is a claw-shaped structure with a right-angled inner end.
[0039] like Figure 10 As shown, taking the hanger rod 1 on the release beam 8 and the support member 4 on the first door leaf 9 as an example, as the hanger rod 1 moves downward from above the support member 4 under the drive of the release beam 8, when it descends to contact the two support members 4, it will squeeze the two support members 4 and swing downward and pass between the two support members 4. When the hanger rod 1 descends to the first position H1, the locking groove 5 just moves between the two support members 4. At this time, the inner end of the support member 4 swings in the opposite direction and moves towards the hanger rod 1 to enter the locking groove 5 of the hanger rod 1. At this time, when the hanger rod 1 moves upward, it will be locked by the inner end of the support rod and its lower end face of the locking groove 5, and it will not be able to continue to move upward.
[0040] As the boom 1 continues to descend, the upper outer surface of the locking groove 5 continues to press against the support members 4 on both sides, causing them to swing downwards. This continues until the boom 1 moves downwards from the first position H1 to the second position H2. At this point, the inner end of the support member 4 moves away from the boom 1 and disengages from the locking groove 5, thus releasing the restriction on the boom 1's upward movement. After this, the boom 1 moves upwards from the second position H2, and the upper boss 6 of the locking groove 5 presses against the support member 4, causing it to swing in the opposite direction and move away from the boom 1 until the boom 1 is completely disengaged from the support member 4. The support member 4 then returns to its original position.
[0041] As a preferred embodiment, to achieve the reset of the support member 4, the locking device further includes a first reset member 10, which is fixedly installed on the support 3 and abuts against the support member 4. The first reset member 10 is a spring piece, one end of which abuts against the support member 4 to provide a reset force. As a preferred embodiment, a limit block 14 is also provided at the outer end of the support member 4. The function of the limit block 14 is to contact the first reset member 10 when the inner end of the support member 4 swings upward to form a limit, preventing excessive swinging and failure to reset.
[0042] As a preferred embodiment, to achieve the reset of the hanger rod 1 on the door leaf 9, the locking device further includes a second reset member 11, which is mounted on the hanger rod 1 located on the door leaf 9 and connected to the sliding sleeve 2. The second reset member 11 provides an upward pulling force to the hanger rod 1, so that when the hanger rod 1 contacts and locks with the support member 4, the hanger rod 1 will automatically move upward. Specifically, the second reset member 11 is a spring.
[0043] In a preferred embodiment, the boom 1 on the gate leaf 9 contacts the sliding sleeve 2 via a limiting boss 12 at its top, thereby limiting the maximum downward movement of the boom 1 during gate opening. That is, when the gate leaves 9 are locked by the locking device, horizontal relative displacement cannot occur between the gate leaves 9, but vertical relative displacement can occur. Therefore, when the hoist performs the gate opening operation, the gate leaves 9 will move upward under the opening pull, thus creating a gap between the gate leaves 9. The gap reaches its maximum when the limiting boss 12 contacts the top surface of the sliding sleeve 2. Therefore, the limiting boss 12 can also be made adjustable, allowing the size of the gap between the gate leaves 9 to be adjusted by adjusting the position of the limiting boss 12 on the boom 1.
[0044] In a preferred embodiment, the hanger 1 is restricted to its maximum downward movement during unlocking by contacting the sliding sleeve 2 of the lower door leaf 9 at its bottom. After the door leaf 9 is placed into the door slot, the hoist operates the hanger 1 on the release beam 8 to descend, thereby pressing the hanger 1 on each door leaf 9 downward. When the bottom of the hanger 1 of the penultimate door leaf 9 contacts the top of the sliding sleeve 2 of the last door leaf 9, it can no longer descend. At this point, the hanger 1 has been unlocked from the support members 4 on both sides. Controlling the hoist to lift the release beam 8 will reset the hangers 1 of all door leaves 9.
[0045] As a preferred example, to facilitate the locking and unlocking operation of the suspension rod 1 on the release beam 8 to the lower door leaf 9, the length of the suspension rod 1 on the release beam 8 is greater than the length of the suspension rod 1 on the door leaf 9. When the lower half of the suspension rod 1 on the release beam 8 is inserted into the hole on the door leaf 9, the rest is still exposed, making it convenient for the operator to observe the descent height.
[0046] As a preferred example, the boom 1 includes a boom body and a locking head 13 threadedly mounted to the bottom of the boom body. The outer surface of the locking head 13 is provided with a locking groove 5. This connection method facilitates the disassembly of the boom body and the locking head 13, thereby enabling the entire boom 1 to be disassembled from the sliding sleeve 2.
[0047] This invention also provides a stacked beam gate system, comprising a stacked beam gate composed of multiple gate leaves 9 and an opening and closing device for lifting the stacked beam gate. After the gate leaves 9 are placed into the gate slot, adjacent gate leaves 9 are locked together by an automatic locking device. After locking, when the gate needs to be opened, the opening and closing device locks the first gate leaf 9 through the lifting rod 1 on the release beam 8, and then all gate leaves 9 can be lifted upwards. After being lifted, a gap is formed between the gate leaves 9, allowing water from the water-facing side to flow into the water-returning side through the gap. The advantage of this structure is that, in the initial stage of opening the gate, the first gate leaf 9 is lifted first. When the gap between the first and second gate leaves 9 reaches its maximum, the second gate leaf 9 begins to be lifted, and so on until all gate leaves 9 are lifted. That is to say, the initial load of the hoist is equivalent to the weight of the first gate leaf 9, so the instantaneous load is much smaller than the maximum load, greatly reducing the instantaneous power of the hoist and thus reducing the failure rate of the hoist. Moreover, the gaps between the door leaves 9 are designed to allow water to flow to the other side, thereby reducing the pressure difference between the two sides of the last few door leaves 9, thus reducing the risk of the last few door leaves 9 being deformed by pressure, and helping to extend the service life of the door leaves 9.
