Description

Technical Field

[0001] This invention relates to the field of hydraulic gate hoisting technology, and in particular to a hydraulic gate hoisting machine that facilitates stroke control. Background Technology

[0002] Hydraulic gate hoists are commonly used in various small and medium-sized water conservancy and water station projects to control the opening and closing of gates. In order to detect the opening value of the gate, existing hydraulic gate hoists usually have displacement sensors to detect the gate's stroke. When opening and closing the gate, the forward and reverse rotation of the motor drives the piston rod of the hydraulic cylinder to move the gate back and forth, thereby achieving the purpose of opening and closing the gate.

[0003] For example, CN112049838A discloses an automatic displacement control hydraulic cylinder and a gate opener. It includes a cylinder body and a piston movably disposed within the cylinder body. The piston is fixedly connected to a piston rod. A magnetostrictive displacement sensor is located at the end of the piston rod. A hole is provided inside the piston rod, penetrating the piston and communicating with the rodless chamber. The magnetostrictive displacement sensor is fixedly connected to a detection rod, which is located within the hole. A fixed rod is also provided, with one end fixedly connected to the bottom of the rodless chamber of the cylinder body and the other end located within the hole. A magnetic ring is located at the end of the fixed rod, and the magnetic ring is sleeved with the detection rod. The relative displacement between the piston and the cylinder body is detected by the relative movement of the detection rod and the magnetic ring. In the gate opener, the cylinder body of the hydraulic cylinder is fixedly connected to the gate. A frame is provided above the gate, and the piston rod is connected to the frame. The piston rod end of the hydraulic cylinder is located at the top of the frame. The structure of this invention avoids the magnetostrictive displacement sensor being immersed in water for extended periods and facilitates on-site maintenance and replacement.

[0004] CN117248505A discloses a high-stability hydraulic gate hoist, belonging to the field of water conservancy equipment technology. It includes a gate and a hydraulic cylinder located within an installation frame. The installation frame includes a bottom plate, a top plate, and two side plates, forming a rectangular structure. The gate is movably disposed between the two side plates. The hydraulic cylinder is installed on the lower surface of the top plate. A connecting box is fixed to the top of the gate, and the piston rod of the hydraulic cylinder is connected to the connecting box. Two sets of locking devices are provided between the top plate and the gate. This invention utilizes locking devices to lock the gate's position when the hydraulic gate hoist is used to raise it, thereby reducing the weight on the hydraulic cylinder. Even with prolonged suspension, the high stability of the hydraulic gate hoist is maintained, reducing safety hazards.

[0005] However, when closing the gate, in order to ensure the gate's water-stopping effect, it is necessary to first check whether there is any debris in the slide and clean it. However, checking the slide and cleaning the debris takes a long time, resulting in a heavy workload for the user and affecting the ease of use of the hydraulic gate hoist. Summary of the Invention

[0006] In view of this, the present invention provides a hydraulic gate hoist with convenient stroke control, which can automatically clean impurities adhering to the gate, effectively avoiding the situation of excessive impurities adhering to the gate, avoiding the inconvenience of manual gate cleaning, and preventing mechanical damage to the impurity cleaning scraper, thus ensuring the service life of the hydraulic gate hoist. It can also reduce the weight on the limit hydraulic cylinder, preventing the stability of the limit hydraulic cylinder from being affected by long-term suspension, reducing safety hazards, and improving the safety of the hydraulic gate hoist. Furthermore, it can prevent impurities or garbage in the water from getting stuck in the gate guide slide and affecting the gate's water-stopping effect, while also preventing cement concrete from entering the gate guide slide during pouring. This effectively avoids the need for manual inspection of the gate guide slide, the inconvenience of frequent garbage cleaning, saves a lot of time, reduces the user's workload, improves the ease of use of the hydraulic gate hoist, and ensures the effectiveness of the hydraulic gate hoist.

[0034] The cleaning structure includes a debris discharge outlet 101 and a first limiting baffle 103. There are two debris discharge outlets 101, which are respectively opened on the left and right sides of the gate guide slide 1. There are two first limiting baffles 103, which are respectively fixedly connected to the left and right sides of the gate guide slide 1.

[0035] The cleaning structure also includes an impurity cleaning scraper 104 and a reset scroll spring 105; the impurity cleaning scraper 104 is rotatably connected to the upper part of the gate guide slide 1; there are two reset scroll springs 105, and the impurity cleaning scraper 104 is elastically connected to the gate guide slide 1 through the two reset scroll springs 105.

[0036] The first limiting structure includes a second limiting baffle 201 and a first reset elastic element 202; multiple second limiting baffles 201 are provided, and multiple second limiting baffles 201 are evenly distributed and slidably connected to the upper part of the positioning mounting frame 2; multiple first reset elastic elements 202 are provided, and multiple second limiting baffles 201 are elastically connected to the positioning mounting frame 2 through multiple first reset elastic elements 202.

[0037] The first limiting structure also includes a first limiting metal plate 203 and a second electromagnet 204; multiple first limiting metal plates 203 are provided, and multiple first limiting metal plates 203 are evenly distributed and fixedly connected to the outside of multiple second limiting baffles 201; multiple second electromagnets 204 are provided, and multiple second electromagnets 204 are evenly distributed and fixedly connected to the inside of the positioning mounting frame 2, and the control circuits of multiple second electromagnets 204 are all connected in parallel with the control circuit of the limiting hydraulic cylinder 3.

[0038] The first limiting structure also includes an anti-accumulation ramp 102 and a matching groove 402; the anti-accumulation ramp 102 is fixedly connected to the lower part of the gate guide slide 1; the matching groove 402 is opened at the lower part of the water-blocking gate 4.

[0039] The first limiting structure also includes a position limiting plate 401 and a sealing rubber gasket 403; two position limiting plates 401 are provided, and the two position limiting plates 401 are fixedly connected to the left and right sides of the water-blocking gate 4 respectively; the sealing rubber gasket 403 is bonded to the inner side of the mating groove 402.

[0040] The specific usage and function of this embodiment are as follows: The gate guide slide 1 and the positioning mounting bracket 2 are cast into the river channel. When the gate needs to be closed, the limiting hydraulic cylinder 3 is activated. At this time, the second electromagnet 204 is energized to attract the first limiting metal plate 203 and the second limiting baffle 201 to retract. After the second limiting baffle 201 retracts, it no longer blocks the position limiting plate 401. The limiting hydraulic cylinder 3 can push the water-blocking gate 4 to move downward. When the water-blocking gate 4 moves downward, it will squeeze the sliding baffle 5, causing the sliding baffle 5 to retract into the gate guide slide 1. The dust in the gap between the gate guide slide 1 and the sliding baffle 5 will fall into the debris discharge outlet 101. After the mating groove 402 below the water-blocking gate 4 is engaged with the anti-accumulation inclined platform 102, the gate is completely closed. The sealing rubber gasket 403 can engage the mating groove 402 with the anti-accumulation inclined platform 102. The gap between the inclined platforms 102 is compensated; the displacement sensor can monitor the movement distance of the gate in real time. After the gate moves to the appropriate position, the displacement sensor can send a signal to the control system in time to stop the operation of the limit hydraulic cylinder 3. After the limit hydraulic cylinder 3 is de-energized, the first reset elastic element 202 will push the second limit baffle 201 to reset, so that the second limit baffle 201 limits the position limiting plate 401; when the gate is open, the impurity cleaning scraper 104 will always be in contact with the water gate 4 due to the limit of the first limit baffle 103. As the water gate 4 moves, the impurity cleaning scraper 104 will scrape off the impurities adhering to the water gate 4. After the water gate 4 is fully opened, the reset spiral spring 105 can make the impurity cleaning scraper 104 swing when it is pushed.

[0041] Example 2:

[0044] The second limiting structure includes a first electromagnet 106 and a second reset elastic element 501. There are two first electromagnets 106, which are fixedly connected to the left and right sides of the gate guide slide 1, respectively.

[0046] The specific usage and function of this embodiment: When the limiting hydraulic cylinder 3 is energized, the first electromagnet 106 is also energized. At this time, the first electromagnet 106 will attract the second limiting metal plate 601 and the limiting rod 6 to slide upward away from the position limiting hole 7, so that the sliding baffle 5 will automatically retract into the gate guide slide 1 after being squeezed by the water-blocking gate 4. The second reset elastic element 501 can push the sliding baffle 5 to reset after the valve is opened. After the limiting hydraulic cylinder 3 is de-energized, the first electromagnet 106 is also de-energized. The third reset elastic element 602 pushes the limiting rod 6 to reset and re-insert it into the position limiting hole 7 to position the sliding baffle 5.
