[0031] As shown in Figure 1 and Figure 2As shown, the dismounting tool of the quick connector comprises a hoisting assembly 1 and a dismounting assembly 2. The hoisting assembly 1 comprises a frame body 11, a plurality of supporting hoisting members 12 and a plurality of hoisting connecting members. The plurality of supporting hoisting members 12 are arranged at the upper end of the frame body 11 in a horizontally adjustable manner, and the plurality of hoisting connecting members are connected to the plurality of supporting hoisting members 12 one by one. The end of the hoisting connecting member away from the supporting hoisting member 12 is configured to be connected to the quick connector to hoist the quick connector. The dismounting assembly 2 comprises a supporting top plate 21, two clamping members 22, two pressing members 23 and two first fasteners 24. The two clamping members 22 are arranged at the two ends of the supporting top plate 21 along the extension direction of the supporting top plate 21. One end of each clamping member 22 penetrates the supporting top plate 21 and is threadedly connected with any first fastener 24, and the other end of the clamping member 22 is configured to be clamped with the dynamic sealing surface flange plate of the quick connector. One end of each pressing member 23 is detachably connected with the supporting top plate 21, and the other end is configured to be tightly connected with the dynamic sealing surface flange plate.

[0032] When the quick connector needs to be overhauled, first, the frame body 11 of the hoisting assembly 1 is moved to the quick connector, the plurality of supporting hoisting members 12 are adjusted according to the size of the quick connector, then the hoisting connecting member is connected with the quick connector to hoist the quick connector to prevent it from falling off after being dismounted, and the hoisting position of the quick connector can be adjusted by adjusting the position of the supporting hoisting member 12, thereby facilitating subsequent dismounting. Then, one end of the two clamping members 22 is tightly connected with the dynamic sealing surface flange plate of the quick connector, and the other end is connected to the supporting top plate 21. Then, the two clamping members 22 are clamped with the dynamic sealing surface flange plate, and the clamping member 22 is threadedly connected with the first fastener 24 through the supporting top plate 21, so as to mount the dismounting assembly 2 on the dynamic sealing surface flange plate of the quick connector. Then, the first fastener 24 is rotated by the worker in the direction close to the dynamic sealing surface flange plate, so that the clamping member 22 moves away from the dynamic sealing surface flange plate relative to the first fastener 24, thereby driving the dynamic sealing surface flange plate to gradually move away from the quick connector body by the clamping member 22, so as to separate the dynamic sealing surface and the static sealing surface, thereby replacing the sealing element on the static sealing surface. The dismounting tool has a simple structure and is easy to operate, can improve the work efficiency of maintenance, and can safely dismount the quick connector to avoid clamping the worker and ensure the safety of the maintenance work.

[0033] Exemplarily, the first fastener 24 comprises a nut, and the hoisting connecting member comprises a steel wire rope.

By arranging the connecting plate 25, the two clamping pieces 22 can be further connected, and the connection strength between the two clamping pieces 22 can be improved. At the same time, the connecting plate 25 is parallel to the dynamic sealing surface flange in the horizontal direction, so that the two clamping pieces 22 can always be kept synchronous during the dismounting process, that is, the two clamping pieces 22 drive the dynamic sealing surface flange to move the same distance, so that the dynamic sealing surface flange always moves outward in parallel, and the dismounting work can be smoothly carried out.

[0035] It should be noted that the length of the connecting plate 25 is the same as the outer diameter of the dynamic sealing surface flange.

[0036] Optionally, as shown in the drawings, Figure 2 As shown, the dismounting tool of the quick connector further comprises a plug-in piece and a second fastener 4.
