[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A pipeline fixing frame for natural gas pipeline detection: comprising a support frame 1, a mobile frame 11 is slidably connected to the surface of the support frame 1, a mounting frame 12 is slidably connected to the surface of the mobile frame 11, a clamping block 13 is fixedly installed on the surface of the mounting frame 12, a lifting mechanism is arranged at the bottom of the support frame 1, and the lifting mechanism comprises a bottom plate 2, the bottom plate 2 is arranged below the support frame 1, a fixing block 21 is fixedly connected to the surface of the bottom plate 2, a motor 22 is fixedly connected to the surface of the fixing block 21, a bidirectional screw rod 23 is fixedly connected to the output shaft of the motor 22, a square nut 24 is threadedly connected to the surface of the bidirectional screw rod 23, an adjusting rod 25 is rotatably connected to the surface of the square nut 24, and the end of the adjusting rod 25 away from the square nut 24 is rotatably connected to the bottom of the support frame 1, and the mounting mechanism comprises a bottom plate 2, the bottom plate 2 is arranged below the support frame 1, a fixing block 21 is fixedly connected to the surface of the bottom plate 2, a motor 22 is fixedly connected to the surface of the fixing block 21, a bidirectional screw rod 23 is fixedly connected to the output shaft of the motor 22, a square nut 24 is threadedly connected to the surface of the bidirectional screw rod 23, an adjusting rod 25 is rotatably connected to the surface of the square nut 24, and the adjusting rod 25 is rotatably connected to the bottom of the support frame 1 at one end thereof. A mounting mechanism is provided on the surface of the frame 12, and the mounting mechanism includes a limit frame 3, the limit frame 3 is fixedly connected to the surface of the mounting frame 12, a limit plate 31 is inserted on the surface of the mounting frame 12, and a latch 32 is inserted on the surface of the limit plate 31. The pipe fixing frame can lift the support frame 1, thereby changing the clamping height of the pipe, which is convenient for workers to detect the pipe and improves the flexibility of the pipe fixing frame. The support frame 1 can be lowered to the top of the bottom plate 2, so that the support frame 1 and the bottom plate 2 are in a folded state, which is convenient for changing the position of the pipe fixing frame. A triangular slot for clamping the pipe is provided on the clamping block 13, and the mounting frame 12 can replace the clamping block 13 through the mounting mechanism, so as to facilitate clamping and fixing pipes of different diameters.

[0024] Furthermore, the motor 22 drives the bidirectional screw 23 to rotate on the fixed block 21 through the output shaft. The bidirectional screw 23 drives the square nut 24 to slide on the base plate 2 during the rotation. Four groups of square nuts 24 are provided. During the sliding process, the square nuts 24 drive the support frame 1 to rise and fall horizontally on the base plate 2 through the adjusting rod 25.

[0025] Furthermore, the base plate 2 and the support frame 1 are parallel to each other, two groups of bidirectional screw rods 23 are arranged on the surface of the base plate 2, and two groups of square nuts 24 are arranged on each group of base plate 2. The two groups of square nuts 24 on the bidirectional screw rods 23 slide in opposite directions on the base plate 2. When the square nuts 24 approach each other, the horizontal height of the support frame 1 decreases, and when the square nuts 24 move away from each other, the horizontal height of the support frame 1 increases.

[0026] Furthermore, the square nut 24 drives one end of the adjusting rod 25 to rotate at the bottom of the support frame 1 during the sliding process, and the other end of the adjusting rod 25 moves on the surface of the square nut 24. The base plate 2 supports the support frame 1 through the adjusting rod 25. During the rotation of the adjusting rod 25, the supporting height of the support frame 1 is changed, thereby changing the relative distance between the support frame 1 and the base plate 2.

[0027] Furthermore, the limiting frame 3 is in an "L" shape, and a groove is formed on the surface of the mounting frame 12. The clamping block 13 is snap-connected to the groove. The limiting frame 3 limits the position of the clamping block 13 on the mounting frame 12. A guide hole is opened on the surface of the mounting frame 12, and the clamping block 13 passes through the guide hole of the mounting frame 12. The guide hole of the clamping block 13 limits the top of the clamping block 13 on the mounting frame 12.

[0028] Furthermore, a rectangular hole is opened at the top of the mounting frame 12, and the cross-section of the limiting plate 31 is "L"-shaped. The limiting plate 31 is inserted into the rectangular hole of the mounting frame 12, and the top of the limiting plate 31 is in contact with the top of the mounting frame 12. The limiting plate 31 limits the clamping block 13 on the surface of the mounting frame 12.

[0029] Furthermore, two groups of circular holes are opened on the surface of the limiting plate 31 , and the latch 32 is in a “U” shape. The latch 32 is plugged into the circular holes of the limiting plate 31 , and the latch 32 limits the limiting plate 31 to the rectangular hole of the mounting frame 12 .

[0030] Working principle: The output shaft of the motor 22 drives the bidirectional screw rod 23 to rotate on the fixed block 21. During the rotation of the fixed block 21, the two sets of square nuts 24 are simultaneously driven to move in opposite directions on the base plate 2. During the movement, the square nut 24 drives one end of the adjusting rod 25 to rotate at the bottom of the support frame 1, while the other end of the adjusting rod 25 rotates on the square nut 24. The base plate 2 supports the support frame 1 through the adjusting rod 25. The adjusting rod 25 changes the supporting height of the support frame 1 by rotating, thereby realizing the lifting and lowering of the support frame 1, and then realizing the lifting and lowering of the pipeline fixing frame.

[0031] The limiting frame 3 forms a slot on the surface of the mounting frame 12, and the clamping block 13 is passed through the guide hole on the top of the mounting frame 12, and then the clamping block 13 is engaged in its slot, and the pin 32 is inserted into the rectangular hole of the mounting frame 12, and then the pin 32 is inserted into the circular hole of the limiting plate 31. The pin 32 limits the position of the limiting plate 31, and the limiting plate 31 limits the clamping block 13 on the mounting frame 12, thereby realizing the fixed installation of the clamping block 13 on the mounting frame 12. By replacing the clamping block 13 on the mounting frame 12, pipes of different diameters can be clamped and fixed.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
