The driving assembly 3 drives the pry block structure 2 located on the mounting plate 1 to generate a gap between the two flange plates at the pipeline connection, and then the sealing gasket at the flange plate connection is replaced.

[0036] The above-mentioned quick replacement device for the air and water pipeline flange sealing gasket clamps the two mounting plates 1 on the pipeline flange plate connection at which the sealing gasket needs to be replaced through the clamping assembly 4, controls the driving assembly 3 to drive the pry block structure 2 to pry open the two flange plates at the pipeline connection and generate a gap, and then the sealing gasket of the flange plate part is replaced, so that the quick replacement of the sealing gasket is realized.

[0037] The quick replacement device for the air and water pipeline flange sealing gasket provided by the utility model will be described in more detail below in combination with the drawings and specific embodiments.

[0038] In a specific embodiment, with reference to Figure 1 The clamping assembly 4 comprises a plurality of adjusting screws 41 connected between the two mounting plates 1, and an adjusting piece 42 is arranged at the connection between each adjusting screw 41 and the two mounting plates 1, so as to adjust the position of the mounting plate 1 on the adjusting screw 41.

[0039] Specifically, the adjusting screw 41 is arranged in total four, and is located on the upper and lower sides of the pipeline, and the adjusting screw 41 on each side is two, so as to clamp the upper and lower sides of the pipeline, and a through hole is arranged at the corresponding position of the adjusting screw 41 on each mounting plate 1, and the adjusting screw 41 is inserted into the two mounting plates 1, so that the two mounting plates 1 are clamped on the left and right sides of the pipeline. The adjusting piece 42 is arranged at the connection between the mounting plate 1 and each adjusting screw 41, so as to adjust the position of the mounting plate 1 on the adjusting screw 41, and realize the close clamping of the two mounting plates 1 on the left and right sides of the pipeline.

[0040] On the basis of any one of the above-mentioned embodiments, with reference to Figure 1Each adjusting member 42 comprises two adjusting nuts 421 arranged on the adjusting screw 41 and clamped to the corresponding mounting plate 1, and each adjusting nut 421 is threadedly connected to the corresponding adjusting screw 41.

[0041] Specifically, each adjusting screw 41 is provided with threads near the through hole of the mounting plate 1, each adjusting screw 41 is provided with two adjusting nuts 421 at the connection position with the mounting plate 1, and the adjusting nuts 421 are threadedly connected to the corresponding adjusting screw 41, and the two adjusting nuts 421 are clamped to the two sides of the mounting plate 1. When the position of the mounting plate 1 needs to be adjusted, the adjusting nut 421 near the pipeline side is first adjusted to the specified position towards the pipeline, then the mounting plate 1 is moved to the specified position and one side is in contact with the adjusting nut 421 on the inner side, and then the adjusting nut 421 away from the pipeline is adjusted towards the mounting plate 1 to realize clamping of the mounting plate 1, thereby ensuring the stability of the mounting plate 1.

[0042] Based on any one of the above embodiments, referring to Figure 1 Each adjusting nut 421 is provided with a gasket between the adjusting nut 421 and the adjacent mounting plate 1.

[0043] Specifically, the gasket is arranged between each adjusting nut 421 and the mounting plate 1. When the adjusting nut 421 directly contacts the mounting plate 1, the fastening will generate a large extrusion force, which will cause a certain pressure on the mounting plate 1. Without protection for a long time, the mounting plate 1 will be pressed, deformed or even damaged. The gasket can disperse this pressure to protect the mounting plate 1 from being damaged. The selection of the gasket can be selected according to the hardness and characteristics of the mounting plate 1.

[0044] Based on any one of the above embodiments, referring to Figure 1 The pry block structure 2 comprises a wedge block 21 arranged on one side of the mounting plate 1 close to the pipeline, and the driving assembly 3 is used to drive the wedge block 21 to rotate and move towards the two flanges.

[0045] Specifically, the wedge block 21 is composed of two parts, one is a cylindrical connecting part, and the other is a sharp prying head part. The end of the prying head part away from the connecting part can be inserted into the gap between the two flanges. The wedge block 21 is driven by the driving assembly 3 to rotate and move towards the center of the flange, and the structure of the prying head part gradually separates the two flanges, thereby facilitating quick replacement of the sealing gasket inside.

[0046] Based on any one of the above embodiments, referring to Figure 1The driving assembly 3 comprises a mounting cylinder 31 and a jacking rod 32, the mounting cylinder 31 is fixedly arranged on the side of the mounting plate 1 away from the pipeline, a threaded hole is formed in the mounting cylinder 31, and the jacking rod 32 is threadedly connected in the threaded hole. The end of the jacking rod 32 close to the pipeline is fixedly connected with the pry block structure 2.

[0047] Specifically, the mounting cylinder 31 is fixedly arranged on the side of the mounting plate 1 away from the pipeline, the mounting cylinder 31 is a hollow structure, and a threaded hole (not shown in the figure) is formed in the inside of the mounting cylinder 31. The jacking rod 32 is threadedly connected in the threaded hole and is inserted into the mounting cylinder 31. The displacement of the jacking rod 32 relative to the mounting cylinder 31 can be realized by rotating the jacking rod 32. The end of the jacking rod 32 close to the pipeline is fixedly connected with the pry block structure 2. The pry block structure 2 is driven by rotating the jacking rod 32, so as to enter between the two flanges and generate a gap between the two flanges, thereby facilitating the replacement of the sealing gasket.

[0048] On the basis of any one of the above embodiments, with reference to Figure 1 The end of the jacking rod 32 away from the pipeline is fixedly provided with an adjusting grab head 33, and a rubber layer is arranged on the surface of the adjusting grab head 33.

[0051] Specifically, the adjusting structure is arranged at the connection between each adjusting screw 41 and the mounting plate 1. The adjusting structure can effectively adjust the position of the mounting plate 1 relative to the adjusting screw 41, so that the pry block structure 2 is always located at the central part between the two flanges, and the two flanges can be pried open more easily.

[0052] Further, the adjusting structure comprises a waist-shaped hole (not shown in the figure) formed in the mounting plate 1, each adjusting screw 41 is slidingly arranged in the corresponding waist-shaped hole, and the waist-shaped hole is formed along the direction perpendicular to the pipeline.

[0053] Specifically, the waist-shaped holes are arranged on the mounting plate 1, both ends of each adjusting screw 41 are inserted into the corresponding waist-shaped hole, the horizontal height of the adjusting screw 41 can be adjusted in the waist-shaped hole, and the adjusting screw 41 is fixed through the adjusting nut 421, so that the position of the mounting plate 1 relative to the adjusting screw 41 is adjusted.

[0054] The various embodiments are described in the specification by progressive stages, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between various embodiments can be referred to each other.

[0055] The above has carried out the detailed introduction to the quick replacement device for the air and water pipeline flange sealing pad provided by the utility model.
