[0030] A manual emergency door-dropping device for a hydraulic gate comprises a hydraulic gate body 1 and mounting columns 11 arranged on both sides of the hydraulic gate body 1, a hydraulic push rod 14 is fixedly connected to the surface of the hydraulic gate body 1 through a mounting seat 12, a gate body 13 is arranged on the surfaces of the two mounting columns 11, and the gate body 13 is slidably connected to the mounting columns 11 through a slide groove;

[0031] In this implementation scheme: After checking the public (announcement) number: CN217056390U discloses an assembled hydraulic gate. In order to solve the technical problems existing in this prior art, such as the above background technology disclosure that "when an emergency such as a fire occurs on one side of the hydraulic gate, it is necessary to evacuate the crowd and then quickly close the hydraulic gate to achieve fire prevention and smoke isolation, and the hydraulic gate cannot be manually quickly closed". This problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a quick-release component 2 and a support component 3 are added on this basis.

[0032] More specifically:

[0033] like Figures 1 to 5 As shown;

[0034] Combining the above:

[0035] In order to realize manual and rapid closing of the hydraulic gate, the manual emergency door-dropping device for the hydraulic gate also includes a quick-release assembly 2 arranged on the surface of the gate body 13;

[0036] The quick-release assembly 2 includes a fixed column 22 fixedly connected to the surface of the gate body 13, the output shaft of the hydraulic push rod 14 is fixedly connected to the fixed block 21, two positioning blocks 26 are symmetrically arranged on the surface of the fixed block 21, and the surfaces of the two positioning blocks 26 are fixedly connected to the positioning plate 24, and a limiting groove 25 is provided inside the positioning plate 24. The fixed column 22 is inserted into the limiting groove 25, and the surface of the positioning plate 24 is rotatably connected to a handle 212 through a bearing seat.

[0037] In this embodiment: when it is necessary to manually close the hydraulic gate, the handle 212 is pulled, and the positioning plate 24 will move away from the gate body 13, thereby releasing the limit on the gate body 13, and the gate body 13 will fall quickly, thereby realizing manual and rapid closing of the hydraulic gate.

[0038] It should be noted that the two positioning blocks 26 will hook the fixing block 21 to strengthen the position limitation of the gate body 13 .

[0039] Going further:

[0040] In an optional embodiment, a limiting ring 27 is provided inside the limiting groove 25, and the limiting ring 27 is rotatably connected to the limiting groove 25 and the positioning plate 24, and a plurality of limiting blocks 28 are evenly and fixedly connected to the inner wall of the limiting ring 27, and three positioning grooves 23 are evenly provided inside the fixed column 22, and the limiting blocks 28 are slidably connected to the fixed column 22 through the positioning groove 23, and a force rod 29 is fixedly connected to the surface of the limiting ring 27, and each positioning groove 23 is an L-shaped structure.

[0041] In this embodiment: when the positioning plate 24 needs to be taken out, force is applied to the force rod 29, the limit block 28 will rotate inside the limit groove 25, and the limit block 28 will slide inside the positioning groove 23, thereby releasing the limit on the positioning plate 24, and the positioning plate 24 can be taken out.

[0042] Going further:

[0043] In an optional embodiment, one end of the force rod 29 away from the limiting ring 27 is fixedly connected to a fixing ring 210, and an insertion rod 211 is slidably connected inside the fixing ring 210. A fixing groove is opened on the surface of the gate body 13, and the insertion rod 211 is inserted inside the fixing groove.

[0044] In this embodiment, when the limit block 28 needs to be released, the insertion rod 211 is pulled in a direction away from the gate body 13 until the insertion rod 211 slides out of the fixing groove, thereby releasing the limit block 28 .

[0045] Going further:

[0046] In an optional embodiment, it further includes a support assembly 3 disposed inside the mounting column 11;

[0047] The support assembly 3 includes an airbag 31 symmetrically arranged inside the two mounting columns 11. The two ends of the airbag 31 are fixedly connected to the gate body 13 and the mounting column 11 respectively. Several exhaust valves 32 are evenly installed inside the airbag 31, and several intake valves 33 are installed on the side of the airbag 31 away from the exhaust valve 32.

[0048] In this embodiment: when the gate body 13 falls, the airbag 31 will exert a certain supporting force on the gate body 13 to prevent the gate body 13 from being damaged due to the rapid descent of the gate body 13. When the airbag 31 is compressed, the exhaust valve 32 will discharge the air inside the airbag 31 to prevent the airbag 31 from bursting. When the airbag 31 is stretched, air will enter the interior of the airbag 31 through the intake valve 33.

[0049] It should be noted that the displacement of the intake valve 33 is larger than the displacement of the exhaust valve 32 .

[0050] The working principle and use process of the utility model are as follows: when the hydraulic gate needs to be closed manually, the handle 212 is pulled, and the positioning plate 24 will move away from the gate body 13, thus releasing the limit on the gate body 13, and the gate body 13 will fall down quickly, thus realizing the manual and quick closing of the hydraulic gate. When the positioning plate 24 needs to be taken out, force is applied to the force rod 29, and the limit block 28 will rotate inside the limit groove 25, and the limit block 28 will slide inside the positioning groove 23, thus releasing the limit on the positioning plate 24, and the positioning plate 24 can be taken out. When the limit block 28 is limited, the insertion rod 211 is pulled in the direction away from the gate body 13 until the insertion rod 211 slides out of the fixing groove, and the limit on the limit block 28 is released. When the gate body 13 falls, the airbag 31 will exert a certain supporting force on the gate body 13 to prevent the gate body 13 from being damaged due to the rapid descent of the gate body 13. When the airbag 31 is compressed, the exhaust valve 32 will discharge the air inside the airbag 31 to prevent the airbag 31 from bursting. When the airbag 31 is stretched, air will enter the interior of the airbag 31 through the intake valve 33.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
