[0040] One end of the second connecting rope 203f is fixedly connected to one end of the jack 202.

[0041] It should be noted that the mounting bracket 203a is fixedly installed at the bottom end of the vertical plate 201. A rotating shaft 203b is rotatably connected to the mounting bracket 203a. A first wire reel 203c and a second wire reel 203d are fixedly connected to the outer wall of the rotating shaft 203b. A first connecting rope 203e and a second connecting rope 203f are respectively wound around the first wire reel 203c and the second wire reel 203d, and their winding directions are opposite. When the jack 202 extends to pull the first connecting rope 203e and drives the first wire reel 203c to rotate and release the first connecting rope 203e, it will drive the second wire reel 203d to rotate and wind the second connecting rope 203f through the rotating shaft 203b. A hook 203h is fixedly connected to the outer wall of one side of the mounting bracket 203a. In the non-working state, hanging the connecting assembly 204 on the hook 203h can prevent the second connecting rope 203f from being wound together.

[0042] Further, the reset member 203g includes a mounting shell 203g-1 provided at the bottom of the mounting bracket 203a, and a torsion spring 203g-2 provided in the inner cavity of the mounting shell 203g-1;

[0043] Both ends of the torsion spring 203g-2 are fixedly connected to the inner wall of the mounting shell 203g-1 and the outer wall of the rotating shaft 203b respectively.

[0044] It should be noted that the mounting shell 203g-1 is fixedly installed at the bottom end of the mounting bracket 203a. A torsion spring 203g-2 is provided in the mounting shell 203g-1. Both ends of the torsion spring 203g-2 are fixedly connected to the inner wall of the mounting shell 203g-1 and the outer wall of the rotating shaft 203b respectively.

[0045] Specifically, the connecting assembly 204 includes a connecting block 204a provided at one end of the second connecting rope 203f, a bolt 204b penetrating through the connecting block 204a, and a nut 204c provided at one end of the bolt 204b.

[0046] It should be noted that the connecting block 204a is fixedly connected to one end of the second connecting rope 203f. A groove is provided on the connecting block 204a. A bolt 204b penetrates through the connecting block 204a, and a nut 204c is threadedly connected to one end of the bolt 204b.

[0047] During use, the connecting block 204a is clamped into the connecting ear of the gate valve, the bolt 204b is passed through the connecting block 204a and the connecting ear, and then the nut 204c is screwed on;

[0048] Start the jack 202. The jack 202 extends and pulls the first connecting rope 203e to drive the first wire reel 203c to rotate. Release the first connecting rope 203e. When the first wire reel 203c rotates, it will drive the rotating shaft 203b to rotate. When the rotating shaft 203b rotates, it will wind up the torsion spring 203g-2, and at the same time drive the second wire reel 203d to rotate and wind the second connecting rope 203f, so as to realize pulling the gate valve. After pulling out the gate valve, the jack 202 contracts, and the torsion spring 203g-2 winds up, driving the rotating shaft 203b to rotate, winding up the first wire reel 203c, tightening the first connecting rope 203e. After removing the connecting block 204a, wind the second connecting rope 203f around the second wire reel 203d and hang it on the hook 203h.

[0049] In summary, by pulling the first connecting rope 203e with the jack 202 to drive the first wire reel 203c to rotate, releasing the first connecting rope 203e, and at the same time driving the second wire reel 203d to rotate and wind the second connecting rope 203f through the rotating shaft 203b, the connection between the gate valve and the hydraulic cylinder is pulled out of the gate valve frame, realizing the replacement of the hydraulic cylinder of the gate valve, and solving the problem that it is inconvenient to replace the hydraulic cylinder of the gate valve when a failure occurs and jams during the reciprocating movement of the gate valve.

[0050] Embodiment 3

[0051] Refer to Figure 1 - Figure 4 This is the third embodiment based on the second embodiment of the present invention. This embodiment further provides a clamping unit 300, including a fixed tube 301 arranged in the inner cavities of the clamping plate 101 and the connecting plate 102, a push plate 302 slidably arranged in the inner cavity of the fixed tube 301, a push rod 303 arranged on one side of the push plate 302, and a tension spring 304 arranged between the push rod 303 and the mounting seat 103.

[0052] It should be noted that the fixed tube 301 is fixedly connected to the inner cavities of the clamping plate 101 and the connecting plate 102, and a push plate 302 is slidably connected in the fixed tube 301. A push rod 303 is fixedly connected to the outer wall of one side of the push plate 302, and a tension spring 304 is arranged between the push rod 303 and the mounting seat 103. The tension spring 304 can pull the push rod 303 to always contact the outer wall of one side of the vertical plate 201.

[0053] When in use, when the clamping plate 101 is clamped into the gate valve frame, the weight of the jack 202 will drive the vertical plate 201 to rotate and squeeze the push rod 303. Under the action of the gravity of the jack 202, the push rod 303 will push the push plate 302 to slide inward, contact and fit with the gate valve frame. When the jack 202 extends, it will squeeze the push rod 303 again to make the push plate 302 fit completely.

[0054] In summary, under the gravitational action of the jack 202, the push plate 302 is first pushed into contact with the gate frame. When the jack 202 extends, it will squeeze the push rod 303 again to fit completely with the gate frame and be fixed, which can solve the problem that when the groove width of the clamping plate 101 is greater than the gate frame, it cannot be directly clamped on the gate frame.

[0055] Embodiment 4

[0056] Refer to Figure 1 - Figure 5 This is the fourth embodiment based on the third embodiment of the present invention. This embodiment further provides a locking unit 400, which includes a fixed seat 401 arranged in the inner cavity of the connecting plate 102, a sliding plate 402 slidably arranged on the inner wall of the fixed seat 401, a reverse tooth groove 403 opened on the outer side of the sliding plate 402, and a control switch 404 arranged on one side of the reverse tooth groove 403;

[0057] One end of the sliding plate 402 is fixedly connected to one side of the vertical plate 201.

[0058] It should be noted that the fixed seat 401 is fixed in the inner cavity of the connecting plate 102. One end of the sliding plate 402 is fixedly connected to the outer wall of one side of the vertical plate 201. The sliding plate 402 is slidably connected to the fixed seat 401. The sliding plate 402 is an arc-shaped plate, and the center of the circle coincides with the rotation center of the vertical plate 201. A reverse tooth groove 403 is opened on the sliding plate 402.

[0059] Furthermore, the control switch 404 includes a base 404a arranged on the upper surface of the connecting plate 102, a positioning block 404b slidably arranged on the inner wall of the base 404a, a control block 404c arranged on the top of the positioning block 404b, and a first spring 404d arranged between the positioning block 404b and the inner cavity of the base 404a.

[0060] Specifically, one end of the positioning block 404b is provided with an inclined surface.

[0061] It should be noted that the base 404a is fixedly installed on the upper surface of the connecting plate 102. A positioning block 404b is slidably connected to the inner wall of the base 404a. One end of the positioning block 404b close to the sliding plate 402 is provided with an inclined surface. A first spring 404d is arranged between the positioning block 404b and the inner cavity of the base 404a, and a control block 404c is fixedly connected to the top of the positioning block 404b.

[0062] During use, when the clamping plate 101 is clamped into the gate frame, the weight of the jack 202 will drive the vertical plate 201 to rotate and squeeze the push rod 303. Under the action of the gravity of the jack 202, the push rod 303 will push the push plate 302 to slide inward, contact and fit with the gate frame. At the same time, when the vertical plate 201 rotates, it will drive the sliding plate 402 to slide in the fixed seat 401, and the positioning block 404b will be stuck in the reverse tooth groove 403, so that the sliding plate 402 can only slide upward. When the jack 202 extends, it will squeeze the push rod 303 again, so that the push plate 302 fits completely. At the same time, if the vertical plate 201 rotates, the sliding plate 402 will continue to slide upward;

[0063] After the work is completed, after the operator holds the jack 202, push the control block 404c to drive the positioning block 404b to retract into the inside of the base 404a, lift the jack 202 upward, and drive the sliding plate 402 to slide downward through the vertical plate 201, loosening the clamping plate 101 and the gate frame.

[0064] In summary, by setting the locking unit to lock the jack 202 on the gate frame, it can prevent the clamping unit 300 from loosening from the gate frame and the jack 202 from falling directly when the jack 202 contracts.

[0065] Embodiment 5

[0066] Refer to Figure 1 - Figure 6 This is the fifth embodiment based on the fourth embodiment of the present invention. This embodiment further provides a fixing unit 500, including a fixing sleeve 501 arranged on the inner wall of the clamping plate 101, a trigger block 502 slidably arranged on the inner wall of the fixing sleeve 501, a second spring 503 arranged between the trigger block 502 and the inner cavity of the fixing sleeve 501, an insertion block 504 slidably arranged on the inner wall of the fixing sleeve 501, a slot 505 opened between the sliding plates 402, a third spring 506 arranged between the insertion block 504 and the fixing sleeve 501, and a trigger assembly 507 arranged on the trigger block 502 and the insertion block 504.

[0067] It should be noted that the fixing sleeve 501 is fixedly installed in the clamping plate 101. A trigger block 502 is slidably connected in the fixing sleeve 501. A second spring 503 is arranged between the trigger block 502 and the inner cavity of the fixing sleeve 501. An insertion block 504 is slidably connected to the inner wall of the fixing sleeve 501. A slot 505 adapted to the insertion block 504 is opened on the sliding plate 402. A third spring 506 is arranged between the insertion block 504 and the fixing sleeve 501

[0068] Further, the triggering component 507 includes a rack 507a disposed on one side of the triggering block 502, a rotating rod 507b rotatably disposed in the inner cavity of the fixed sleeve 501, a gear 507c and a third wire reel 507d disposed on the outer wall of the rotating rod 507b, and a third connecting rope 507e wound around the third wire reel 507d;

[0069] The gear 507c meshes with the rack 507a, and one end of the third connecting rope 507e is fixedly connected to the bottom end of the insertion block 504.

[0070] It should be noted that a rack 507a is fixedly connected to one side of the triggering block 502, a rotating rod 507b is rotatably connected to the inner cavity of the fixed sleeve 501, a gear 507c and a third wire reel 507d are fixedly connected to the outer wall of the rotating rod 507b, the gear 507c meshes with the rack 507a, and a third connecting rope 507e is wound around the third wire reel 507d. One end of the third connecting rope 507e is fixedly connected to the bottom end of the insertion block 504.

[0071] During use, in the normal state, rotating the vertical plate 201 drives the sliding plate 402 to move, so that the insertion block 504 is inserted into the slot 505 to prevent the vertical plate 201 from rotating and injuring the operator in the normal state;

[0072] During installation, when the clamping plate 101 is snapped into the gate frame, the edge of the gate frame will squeeze the triggering block 502, pushing the triggering block 502 into the fixed sleeve 501. During the process of the triggering block 502 retracting into the fixed sleeve 501, it will drive the gear 507c to rotate through the rack 507a. When the gear 507c rotates, it will drive the third wire reel 507d to rotate through the rotating rod 507b, winding the third connecting rope 507e. The third connecting rope 507e will pull the insertion block 504 out of the slot 505 to unlock the sliding plate 402.

[0073] In summary, by rotating the vertical plate 201 to drive the sliding plate 402 to move, so that the insertion block 504 is inserted into the slot 505, it is possible to prevent the vertical plate 201 from rotating and injuring the operator in the normal state.
