Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic hoists, and particularly relates to a hydraulic hoist convenient for controlling the stroke. Background Art

[0002] In various medium and small-sized water conservancy and water station projects, hydraulic hoists are often used to control the opening and closing of gates. In order to detect the opening value of the gate opening and closing, existing hydraulic hoists usually set displacement sensors to detect the stroke of the gate. When opening and closing the gate, the reciprocating motion of the gate is driven by the piston rod of the hydraulic cylinder through the forward and reverse rotation of the motor, so as to achieve the purpose of opening and closing the gate.

[0003] For example, CN112049838A discloses a hydraulic cylinder and a hoist for automatically controlling displacement, which includes a cylinder body, and also includes a piston movably arranged in the cylinder body. The piston is fixedly connected to the piston rod. A magnetostrictive displacement sensor is arranged at the end of the piston rod. A hole penetrating the piston and communicating with the rodless cavity is arranged in the piston rod. The magnetostrictive displacement sensor is fixedly connected to a detection rod, and the detection rod is located in the hole. A fixed rod is also provided. One end of the fixed rod is fixedly connected to the bottom of the rodless cavity of the cylinder body, and the other end is located in the hole. A magnetic ring is arranged at the end of the fixed rod, and the magnetic ring is sleeved on 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 hoist, the cylinder body of the hydraulic cylinder is fixedly connected to the gate, and a frame is arranged above the gate. The piston rod is connected to the frame. The end of the piston rod of the hydraulic cylinder is located at the top of the frame. The structure of the invention avoids the magnetostrictive displacement sensor being soaked in water for a long time, and is convenient for on-site maintenance and replacement.

[0004] CN117248505A discloses a highly stable hydraulic hoist, belonging to the technical field of water conservancy equipment, including a gate and a hydraulic cylinder located in an installation frame. The installation frame includes a bottom plate, a top plate and two side plates. The bottom plate, the top plate and the two side plates form a rectangular structure. The gate is movably arranged between the two side plates. The hydraulic cylinder is installed on the lower surface of the top plate. A connection box is fixed to the top of the gate. The piston rod of the hydraulic cylinder is connected to the connection box. Two groups of locking devices are arranged between the top plate and the gate. The invention uses the locking device to lock the position of the gate when driving the gate to rise by using the hydraulic hoist, so as to reduce the gravity borne by the hydraulic cylinder. Even when hanging for a long time, the high stability of the hydraulic hoist is still ensured, and the potential safety hazard is reduced.

[0005] However, when closing the gate, in order to ensure the water stop effect of the gate, it is necessary to first check whether there is garbage in the slideway and clean the garbage. However, checking the slideway and cleaning the garbage takes a long time, resulting in a large labor burden on the user and affecting the use convenience of the hydraulic hoist. Summary of the Invention

[0031] Among them, the first limiting structure includes a second limiting baffle 201 and a first reset elastic member 202; there are multiple second limiting baffles 201, and the multiple second limiting baffles 201 are evenly distributed and slidably connected to the upper part of the positioning and mounting frame 2; there are multiple first reset elastic members 202, and the multiple second limiting baffles 201 are elastically connected to the positioning and mounting frame 2 through the multiple first reset elastic members 202.

[0032] Among them, the first limiting structure further includes a first limiting metal sheet 203 and a second electromagnet 204; there are multiple first limiting metal sheets 203, and the multiple first limiting metal sheets 203 are evenly distributed and fixedly connected to the outer sides of the multiple second limiting baffles 201; there are multiple second electromagnets 204, and the multiple second electromagnets 204 are evenly distributed and fixedly connected to the inner side of the positioning and mounting frame 2, and the control circuits of the multiple second electromagnets 204 are all connected in parallel with the control circuit of the limiting hydraulic cylinder 3.

[0035] Specific usage method and function of this embodiment: Pour the gate guiding slide 1 and the positioning mounting frame 2 into the river channel. When it is necessary to close the gate, start the limit hydraulic cylinder 3. At this time, the second electromagnet 204 is energized to attract the first limit metal sheet 203 and the second limit baffle 201 to retract. After the second limit baffle 201 retracts, it no longer blocks the position limiting plate 401; the limit hydraulic cylinder 3 can push the water retaining gate 4 downward. When the water retaining gate 4 moves downward, it will squeeze the sliding baffle 5, causing the sliding baffle 5 to retract into the gate guiding slide 1, and the dust in the gap between the gate guiding slide 1 and the sliding baffle 5 will fall into the debris discharge port 101; after the mating card slot 402 below the water retaining gate 4 is clamped with the anti-accumulation inclined platform 102, the gate is completely closed, and the sealing rubber pad 403 can compensate for the gap between the mating card slot 402 and the anti-accumulation inclined platform 102; the displacement sensor can monitor the moving distance of the gate in real time.

After the limit hydraulic cylinder 3 is powered off, the first reset elastic member 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 opened, the impurity cleaning scraper 104 will always be in contact with the water retaining gate 4 under the limitation of the first limit baffle 103. As the water retaining gate 4 moves, the impurity cleaning scraper 104 will scrape off the impurities adhering to the water retaining gate 4. After the water retaining gate 4 is completely opened, the reset scroll spring 105 can make the impurity cleaning scraper 104 swing when the impurity cleaning scraper 104 is subjected to a thrust force.

[0039] The specific usage and function of this embodiment: When the limiting hydraulic cylinder 3 is powered on, the first electromagnet 106 is also powered on. At this time, the first electromagnet 106 will attract the second limiting metal sheet 601 and the limiting insertion rod 6 to slide upward and leave the position limiting hole 7, so that the sliding baffle 5 automatically retracts into the gate guide slide 1 after being squeezed by the water retaining gate 4. The second reset elastic member 501 can push the sliding baffle 5 to reset after the valve is opened. After the limiting hydraulic cylinder 3 is powered off, the first electromagnet 106 is also powered off, and the third reset elastic member 602 pushes the limiting insertion rod 6 to reset and insert into the position limiting hole 7 again to position the sliding baffle 5.
