Description

Technical Field

[0001] The utility model relates to the field of gate hoists, in particular to a hydraulic gate hoist. Background Art

[0002] A gate hoist is a mechanical device used to control the movement of switches such as doors, windows, and gates. It is widely used in construction, subways, railways, water conservancy, chemical industry, etc. In the fields of water conservancy, chemical industry, gate hoists are widely used in various sluices, dam gates, water pump outlets, etc. No matter which field, the application of gate hoists is to control the movement of switches such as doors, windows, and gates to ensure the safety of personnel and the normal operation of equipment.

[0003] A hydraulic gate hoist refers to a gate hoist that uses hydraulic transmission as power for opening and closing. It is a device used to open and close orifices. It is generally composed of a hydraulic system and a hydraulic cylinder. Under the control of the hydraulic system, the inner wall of the piston in the hydraulic cylinder moves back and forth to achieve control of the opening and closing of the gate.

[0004] However, when the existing hydraulic gate hoist is used, the hydraulic cylinder needs to bear the load force in the tilting direction when the gate plate is flipped open and closed. After the hydraulic gate hoist is used for a long time, the hydraulic cylinder in the hydraulic gate hoist is prone to bend, which will affect the service life of the hydraulic cylinder in the hydraulic gate hoist and is not conducive to the use of the hydraulic gate hoist.

[0005] Therefore, we proposed the hydraulic gate hoist. Utility Model Content

[0037] The rotating gate plate 13 can block the water flow, and the sealing block 14 at the bottom of the rotating gate plate 13 can seal the rotating gate plate 13 and the arc groove 16 on the fixed block 15 to avoid leakage when the rotating gate plate 13 blocks the water flow. When the rotating gate plate 13 needs to be rotated and opened, the hydraulic cylinder 5 on the first fixed plate 3 is opened, and the mounting block 1 can fix and limit the first fixed plate 3 in the retention hole 2, which is convenient for the stable use of the first fixed plate 3.

The mounting block 1 can limit the rotating gate plate 13 through the rotating rod 12, so as to stably rotate the rotating gate plate 13. When the rotating gate plate 13 rotates, it can drive the sealing block 14 to rotate along the arc groove 16 on the fixed block 15, so that the sealing block 14 at the bottom of the rotating gate plate 13 is separated from the arc groove 16 on the fixed block 15, so that the water flows through the sealing block 14 at the bottom of the rotating gate plate 13 and the arc groove 16 on the fixed block 15.

[0039] By rotating the rotating gate plate 13 and the sealing block 14, the size of the separation gap between the sealing block 14 at the bottom of the rotating gate plate 13 and the arc groove 16 on the fixed block 15 can be adjusted, which helps to control the size of the water flow passing through, so as to open and close the water flow. When the hydraulic cylinder 5 is used, the output rod of the hydraulic cylinder 5 only needs to be pushed in the horizontal direction and does not need to bear the load force in the inclined direction. During use, the hydraulic cylinder 5 can be prevented from bending, which helps to ensure the service life of the hydraulic cylinder 5.

[0040] During use, when the rotating gate plate 13 and the sealing block 14 are flipped to open and close, the hydraulic cylinder 5 does not need to bear the load force in the tilting direction. After long-term use of the hydraulic gate opener, the hydraulic cylinder 5 in the hydraulic gate opener can be prevented from bending, which helps to ensure the service life of the hydraulic cylinder 5 in the hydraulic gate opener, so as to facilitate the use of the hydraulic gate opener.
