Description

Technical Field

[0001] The utility model relates to the technical field of flange forging clamping, in particular to an anti-dropping clamping device for flange forgings. Background Art

[0002] Flange forgings are a kind of connection components with excellent mechanical properties. They are usually used in pipeline systems to connect pipes to pipes, pipes to valves or equipment. Flange forgings are flanges made by forging process. Their raw materials are usually pipe blanks. The main materials of forged flanges include carbon steel, alloy steel and stainless steel. Clamping devices are used in the processing, inspection, measurement, assembly, installation, transportation and handling of flange forgings.

[0003] The existing clamping device for flange forgings does not have a moisture-proof function when in use. Since the corrosion resistance of carbon steel flange forgings is relatively weak, when processed or transported in a humid environment, the carbon steel flange forgings are exposed to the air, making the flange forgings prone to rust. Therefore, the present application provides an anti-fall-off clamping device for flange forgings to meet the needs. Utility Model Content

[0006] A sealing plug is arranged at the drainage hole, and a sealing gasket is installed on the inner side of the electric telescopic cover.

[0007] The inner cavity of the frame is rotatably provided with two connecting plates, and sliding rods are installed on the connecting plates.

[0008] The outer ring of the slide rod is provided with a slide plate, and the two connecting plates are connected through the slide rod and the slide plate.

DETAILED DESCRIPTION

[0022] The following is a detailed description of a flange forging anti-drop clamping device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides an anti-dropping clamping device for flange forgings, including a frame 1; two moisture-proof mechanisms 2, the sides of the moisture-proof mechanisms 2 are sealed and connected to the frame 1, the moisture-proof mechanisms 2 include a protective cover 201, an electric telescopic cover 202 is arranged on the inner side of the protective cover 201, and a drainage hole 203 is arranged at the bottom of the protective cover 201.

[0024] like Figure 3 and Figure 4 As shown, a sealing plug is provided at the drain hole 203 , and a sealing gasket is installed on the inner side of the electric telescopic cover 202 .

[0025] The main function of the drainage hole 203 is to drain the accumulated water so that it can be quickly drained in case water enters the interior.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, two connecting plates 5 are rotatably provided in the inner cavity of the frame 1 , and sliding rods 6 are installed on the connecting plates 5 .

[0027] The connecting plate 5 is used to drive the arc clamp 3 to move, so as to clamp flange forgings of different sizes.

[0028] like Figure 2 and Figure 5 As shown, a slide plate 7 is provided on the outer ring of the slide rod 6 , and the two connecting plates 5 are connected via the slide rod 6 and the slide plate 7 .

[0029] The slide bar 6 has a guiding function. The slide bar 6 can be used as a guide rail to guide the component to move linearly along a predetermined path, thereby ensuring smooth and precise movement.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, an arc-shaped clamp 3 is installed on one side of the connecting plate 5 close to the moisture-proof mechanism 2, and a plastic pad 4 is installed on the inner side of the arc-shaped clamp 3. The plastic pad 4 is made of high-temperature resistant plastic.

[0031] Since the surface of the carbon steel flange forging is not as smooth as that of stainless steel, care should be taken to prevent surface damage when clamping to avoid scratches or dents caused by friction. The plastic pad 4 has a lower friction coefficient and can effectively avoid scratching the carbon steel surface.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, a rotating threaded rod 9 is provided through the frame 1 , a threaded sleeve 8 is provided on the outer ring of the rotating threaded rod 9 , and one end of the threaded sleeve 8 is connected to the slide plate 7 .

[0033] The function of the rotating threaded rod 9 is to realize the conversion between rotational motion and linear motion. The rotating threaded rod 9 cooperates with the threaded sleeve 8 through the thread on its outer ring. When the rotating threaded rod 9 rotates, the threaded sleeve 8 will move linearly along the trajectory of the thread, thereby driving the slide plate 7 to move.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the protective cover 201 and the electric telescopic cover 202 are both provided with an opening 204 on one side close to the frame 1 for use with the arc clamp 3 .

[0035] The protective cover 201 has a protective function to prevent the flange forging from rusting in a humid environment, and can also effectively prevent the flange forging from detaching during transportation.

[0036] The technical solution provided by the utility model is that when in use, the rotating threaded rod 9 drives the threaded sleeve 8 to move, thereby driving the connecting plate 5 through the slide plate 7 and the slide rod 6, so that the arc clamp 3 clamps the flange forging. When the environment in which the flange is located is relatively humid, the electric telescopic cover 202 is extended through the external switch, so that the moisture-proof mechanism 2 and the frame 1 form a sealed space to prevent moisture from entering the interior and causing rust on the flange forging.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
