It is evenly distributed, and thus, it is possible to prevent loss of fastening force or leakage of a fluid such as gas or liquid.

FIG. 5 is an external perspective view showing the clamping device 40 for pipe fixing of FIG. 1, FIG. 6 is an exploded perspective view showing parts of the clamping device 40 for pipe fixing of FIG. 5, and FIG. 7 is for pipe fixing of FIG. 5 It is a top view showing the clamp device 40.

1 to 7, for example, the clamp device 40 is a device that closes the first flange F1 and the second flange F2 in a circumferential direction to closely contact each other, and the clamp The device 40 is formed to surround at least a portion of the first flange F1 and the second flange F2 and is formed to be elongated in the circumferential direction of the first flange F1 and the second flange F2. The first flange (F1) and the second flange (F2) in a shape surrounding at least another portion of the first portion (40-1), the first flange (F1) and the second flange (F2) The first flange (F1) in a shape surrounding a second portion (40-2) formed in the circumferential direction of at least, and at least another portion of the first flange (F1) and the second flange (F2) The third part 40-3 formed long in the circumferential direction of the second flange F2 and the first part 40-1 The first joint portion J1 installed between the second portion 40-2, the second joint portion J2 installed between the second portion 40-2 and the third portion 40-3, and A tightening device (50) for tightening the first portion (40-1) and the second portion (40-2) in a direction in which the first portion (40-1) and the second portion (40-2) are close to each other ).

More specifically, for example, as shown in the enlarged portion of FIG. 3, the first portion 40-1, the second portion 40-2 and the third portion 40-3 are , A pressure groove (V) having a cross-sectional V-shape may be formed so as to correspond to the first inclined surface (A) of the first flange (F1) and the second inclined surface (B) of the second flange (F2). have.

Therefore, when the first portion 40-1, the second portion 40-2 and the third portion 40-3 are tightened by the fastening device 50, the pressing groove portion V ) Presses the first inclined surface (A) of the first flange (F1) and the second inclined surface (B) of the second flange (F2), so that the first flange (F1) and the second flange (F2) ) Can be brought into close contact with each other.

More specifically, for example, as illustrated in FIGS. 5 to 7, the fastening device 50 includes a first protruding block B1 installed at an end of the first portion 40-1, and The second protruding block B2 and the bolt portion 51-1 formed at one end of the second portion 40-2 or the third portion 40-3 are provided at the first protruding block B1. ) Is pivotally coupled, and the nut portion 51-2 formed at the other end is inserted into the insertion groove G formed in the second protruding block B2 to be screwed forward and backward along the bolt portion 51-1. It may include a tightening handle (51).

Therefore, the operator can screw the bolt portion 51-1 by rotating the nut portion 51-2 of the tightening handle 51 forward and backward, and the agent connected to the bolt portion 51-1. One part 40-1 is pulled in the direction of the third part 40-3, resulting in the first part 40-1, the second part 40-2 and the third part (40-3) can all be tightened.

Conversely, the operator can screw the bolt portion 51-1 by rotating the nut portion 51-2 of the tightening handle 51 backward, and connected to the bolt portion 51-1. The first portion 40-1 is distant from the third portion 40-3, resulting in the first portion 40-1, the second portion 40-2 and the third portion ( 40-3) All this can be loosened.

Therefore, by using the multi-joint clamp device 40 surrounding the flanges F1 and F2 in the circumferential direction, it is possible to maintain a tightly coupled state even in long-term vibration or external force, and the fastening force is applied to all areas in the circular direction of the flange. It works evenly to prevent loss of fastening force or fluid leakage in vulnerable areas.

Meanwhile, as illustrated in FIGS. 5 to 7, the pipe fixing device 100 according to some embodiments of the present invention is engaged by the upper jaw T1 and the lower jaw T2 of the clamp device 40. The ear portion insertion groove portion (for which the ear portion E of the bolt portion 51-1 is inserted so that the portion 62 is installed by forcibly being installed and the bolt portion 51-1 of the tightening handle 51 is not released. 61) may further include an anti-loosening block 60 on which it is formed.

Therefore, the operator secures a sufficient binding force by rotating the tightening handle 51, and then forcibly inserts the anti-loosening block 60 into the third portion 40-3 to secure the bolt portion 51-1. The ear portion E may be inserted into the ear portion insertion groove portion 61 to be inserted.

Therefore, it is of course possible to prevent the loosening of the tightening handle 51 by fixing the ear portion E, and, even if it is loosened, the angle of rotation of the glans head E can be easily checked with the naked eye. It can be prevented.

In addition, for example, as shown in Figures 5 to 7, the pipe fixing device 100 according to some embodiments of the present invention, the clamp device 40 so as to check the first joint portion (J1) with the naked eye An exposed portion (W) exposing the first joint portion (J1) of the formed, the upper jaw (T1) and the lower jaw (T2) of the clamp device 40, the engaging portion (71) is installed to be inhibited , It may further include a gas sensing block 70 is installed inside the gas sensor to detect the leakage of gas.

Therefore, it is possible to easily sense gas in a state in which gas is primarily trapped when a gas leaks using the gas sensing block 70, and visually inspect the joints for damage by exposing the joints through the exposed portion W. At the same time, the gas sensing block 70 can be easily fastened regardless of the shape of the joint.

8 is a perspective view showing an anti-loosening washer 80 of the pipe fixing device 100 of FIG. 4.

For example, as shown in Figure 8, the pipe fixing device 100 according to some embodiments of the present invention, the second pipe 20 so as to be fixed to the floor (1) or the structure so that the agent An anti-loosening washer 80 may be installed between a fixing bolt fixed to the floor or the structure through the 2 flange F2 and the second flange F2.

More specifically, for example, as illustrated in FIG. 8, the anti-loosening washer 80 may be formed of a first washer part 81 and a second washer part 82, and has two washer parts ( 81) A one-way tooth surface 83 may be formed on the contact surface of the 82. Therefore, since the two washers described above are fastened together with the fixing screws or the fixing bolts and can be rotated only in one direction, loosening of the fixing screws or the fixing bolts can be fundamentally prevented.

Meanwhile, the present invention is not limited to the above-described pipe fixing device 100, and may include a pipe fixing clamp device 40.

For example, the clamp device 40 for fixing a pipe according to some embodiments of the present invention may include at least a first flange F1 of the first pipe 10 and a second flange F2 of the second pipe 20. A first part 40-1 formed in a circumferential direction of the first flange F1 and the second flange F2 in a shape surrounding a part, and the first flange F1 and the second flange A second part 40-2 formed long in the circumferential direction of the first flange F1 and the second flange F2 in a shape surrounding at least another part of the F2, and the first part 40 The first joint portion J1 and the first portion 40-1 and the second portion 40-2 installed between -1) and the second portion 40-2 are close to each other. A fastening device 50 for tightening the first portion 40-1 and the second portion 40-2 may be included.

Here, these components may have the same configuration and role as those of the pipe fixing device 100 already described above. Therefore, detailed description is omitted.

Accordingly, the clamp device 40 for fixing pipes according to some embodiments of the present invention is used to connect two pipes for transporting fluid, or to fix a pipe for transporting fluid to a floor or structure. It is possible to apply.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
