[0040] Further, the stretching assembly comprises a gear and a rack plate, gears are horizontally and symmetrically arranged at the top and bottom of the moving platform, a group of rack plates are arranged in the moving platform and overlap in position, the rack plates are matched with the corresponding gears, so that the two ends of the group of rack plates can be synchronously stretched outwards or contracted inwards, and the moving platform is provided with a fixing member capable of locking the position of the rack plate. Specifically, in the embodiment, the fixing member is a screw, the rack plate adjusted to the appropriate position is fixed by the screw, so that the width of the device can be adaptively adjusted according to barrels of different sizes.

[0041] Further, the side wall of the group of rack plates is provided with a first sliding groove in the axial direction, a scale is arranged on the rack plate, the back of the sensor placing table is provided with a pair of sliding blocks, the pair of sliding blocks are respectively slidably connected in the upper and lower first sliding grooves, the opposite ends of the rack plate are connected with a baffle capable of limiting the position of the sensor placing table, so as to prevent the sensor placing table from sliding out of the rack plate.

[0043] In some embodiments, the support assembly comprises a guide rail seat and a connecting plate, a group of guide rail seats are connected through the connecting plate, a second sliding groove and a corresponding scale are arranged on the top of the guide rail seat, and the bottom of the sliding base is slidably connected in the second sliding groove of the guide rail seat.

[0046] In some embodiments, the main structure of the multi-directional adjustment clamp for measuring in the magnetic shielding barrel is made of nylon with self-lubricating function and will not be magnetized.

At the same time, the weight of the device is less than 7 kg, which is light and easy to use. At least 2 kg of objects can be placed on the sensor placement table. Due to the material, weight and operation form, the device will not affect the barrel when measuring in the barrel.

[0047] The implementation principle of the multi-directional adjustment clamp for measuring in the magnetic shielding barrel is as follows:

[0048] By pulling the two rack pull plates, the two rack pull plates are respectively extended along the X-axis, the sensor placement table slides in the first sliding groove of the two rack pull plates, the left and right tracks can be exchanged, and the sensor placement table drives the adjustment sensor to adjust the position of the X-axis.

[0049] By rotating the handle wheel to drive the worm to rotate, due to the transmission action of the worm and the worm gear, the trapezoidal screw can rotate around its own axis. By virtue of the threaded connection between the trapezoidal screw and the moving platform, and the sliding connection between the two ends of the moving platform and the guide rod, the moving platform can adjust the height along the Z-axis, thereby driving the sensor on the sensor placement table to adjust the position of the Z-axis.

[0050] By sliding the sliding base along the second sliding groove on the guide rail base, the sliding base drives the sensor placement platform to move along the X-axis, so that the sensor on the sensor placement platform adjusts the position along the X-axis, and based on the scale on the guide rail base and the scale in the notch between the connecting plate and the sliding base, the distance of the sensor to the bottom of the magnetic shielding barrel can be determined.

[0051] Meanwhile, the device is mainly used for tool clamps for measuring parameters such as magnetic noise and residual magnetism, and the points for obtaining the parameters are generally located inside the barrel and pipeline. Since some extreme positions inside the barrel and pipeline are not effective positions for obtaining and measuring parameters, the device can meet the requirement of moving the sensor to most of the required measuring points.

[0052] Embodiment Two:

[0053] The embodiment is an operating mode of a multi-directional adjusting clamp for measuring inside a magnetic shielding barrel, which comprises the following steps:

[0054] S1, the device is placed in the inner barrel of the measured magnetic shielding barrel, the handle wheel is rotated, the scale on the guide rod is observed, and the moving platform is adjusted to the specified height;

[0055] S2, the rack pull plate is pulled until the rack foot wheel contacts the barrel wall, and the rack pull plate is fixed at this time;

[0056] S3, the sensor placement platform is moved according to the scale on the rack pull plate so as to reach the specified transverse measuring position;

[0057] S4, the length of the scale passing through the notch of the connecting plate is adjusted, then the scale is fixed, and the device is pushed into the barrel;

[0058] S5, since the guide rail foot wheel and the rack foot wheel are in contact with the inner wall of the barrel, the device will move linearly, and the clamp is continuously pushed until the end of the scale abuts against the barrel bottom, at which time the distance between the sensor and the barrel bottom can be determined.
