[0035] The top surfaces of the two hydraulic rods 4 are provided with anti-deviating components 401, and the anti-deviating components 401 include a transverse plate 8, which is fixed to the top of the telescopic ends of the two hydraulic rods 4, an arc block 9 is fixed in the middle of the bottom surface of the transverse plate 8, a strip plate 10 is fixed in the middle of the top surface of the transverse plate 8, and two L-shaped fork plates 11 are fixed on the bottom surface of the strip plate 10. The two L-shaped fork plates 11 are respectively located above the two slide grooves of the U-shaped frame 2, and the outer walls of the two L-shaped fork plates 11 are in sliding contact with the inner wall of the U-shaped frame 2. The inner walls of the two slide grooves of the U-shaped frame 2 are located between the two L-shaped On the motion track of the fork plate 11, the long axis of the magnetostrictive sensor enters the L-shaped fork plate 11, and the L-shaped fork plate 11 slides downward in the slide groove of the U-shaped frame 2. The L-shaped fork plate 11 limits the long axis of the magnetostrictive sensor, so that when the long axis of the magnetostrictive sensor is squeezed by the arc block 9, the long axis of the magnetostrictive sensor will not deviate from the arc groove of the U-shaped frame 2, thereby avoiding the long axis of the magnetostrictive sensor from deviating when the detection device is in use, resulting in poor compression resistance of the long axis of the magnetostrictive sensor in the detection device;

[0036] A limit assembly 402 is provided on the top surface of the strip plate 10, and the limit assembly 402 includes two double-hole plates 12, and the two double-hole plates 12 are fixed on the top surface of the strip plate 10. Sliding holes are provided on both sides of the top surfaces of the two double-hole plates 12. Sliding rods 13 are slidably installed on the inner walls of the sliding holes of the two double-hole plates 12, and discs 14 are fixed on the bottom surfaces of the four sliding rods 13. The bottom surfaces of the four discs 14 are fixedly connected to the top surface of the operating table 1. Through holes are provided on both sides of the front surfaces of the two double-hole plates 12, and the top surfaces of the four discs 14 are on the movement trajectory of the two double-hole plates 12. The sliding rod 13 limits the downward movement of the double-hole plates 12, and the double-hole plates 12 limit the downward movement of the strip plate 10, so that the L-shaped fork plate 11 on the strip plate 10 will not hit the U-shaped frame 2 during the downward movement, so as to avoid the L-shaped fork plate 11 hitting the U-shaped frame 2 when the detection device is in use, causing damage to the equipment.

[0037] When in use, the operating table 1 supports the U-shaped frame 2, and the staff places the long rod of the magnetostrictive sensor in the arc grooves at both ends of the U-shaped frame 2. At the same time, the magnetostrictive sensor housing is placed on the heightening plate 3. Since the long rod of the magnetostrictive sensor is easy to deviate from the initial position during the compression test of the magnetostrictive sensor, the staff uses the touch display screen on the operating table 1 to start the electric cylinder 7, and the electric cylinder 7 uses a hose to extract the oil from the hydraulic rod 4. The telescopic end of the hydraulic rod 4 starts to move downward, and the telescopic end of the hydraulic rod 4 drives the cross plate 8 to move downward, and the cross plate 8 drives the arc block 9 to move downward. In the process of the arc block 9 moving downward, the arc block 9 will contact the long axis of the magnetostrictive sensor, and the arc block 9 squeezes the long axis. The horizontal plate 8 drives the strip plate 10 to move downward, and the strip plate 10 drives the L-shaped fork plate 11 to move downward. During the downward movement of the L-shaped fork plate 11, the long axis of the magnetostrictive sensor enters the L-shaped fork plate 11, and the L-shaped fork plate 11 slides downward in the slide groove of the U-shaped frame 2, so that the L-shaped fork plate 11 restricts the long axis of the magnetostrictive sensor, so that when the long axis of the magnetostrictive sensor is squeezed by the arc block 9, the long axis of the magnetostrictive sensor will not deviate from the arc groove of the U-shaped frame 2, thereby preventing the long axis of the magnetostrictive sensor from deviating from the arc groove of the U-shaped frame 2 when the equipment is detecting, thereby avoiding the problem that when the detection device is in use, the long axis of the magnetostrictive sensor is offset, resulting in poor compression resistance of the long axis of the magnetostrictive sensor when the equipment detects it.

[0038] When the horizontal plate 8 drives the strip plate 10 to move downward, the strip plate 10 drives the double-hole plate 12 to move downward. At the same time, the operating table 1 supports the disc 14, and the disc 14 supports the slide bar 13. The sliding hole of the double-hole plate 12 slides downward on the slide bar 13, so that the slide bar 13 limits the downward movement of the double-hole plate 12, and the double-hole plate 12 limits the downward movement of the strip plate 10, so that the L-shaped fork plate 11 on the strip plate 10 will not hit the U-shaped frame 2 during the downward movement, preventing the L-shaped fork plate 11 from hitting the U-shaped frame 2 when the equipment is in use, thereby avoiding the problem of the L-shaped fork plate 11 hitting the U-shaped frame 2 when the detection device is in use, causing damage to the equipment.

The pressure block 54 is located above the heightening plate 3. The sensor shell on the heightening plate 3 is on the movement trajectory of the pressure block 54. The pressure block 54 squeezes the magnetostrictive sensor housing, so that the device can simultaneously detect the pressure resistance of the magnetostrictive sensor housing during detection, avoiding the detection device being unable to simultaneously detect the pressure resistance of the magnetostrictive sensor housing when in use, resulting in a single and incomplete detection effect of the equipment.

[0040] The shell compression device 5 also includes two square blocks 55, two L-shaped rods 56 and a baffle 57. The two square blocks 55 are fixed on both sides of the top surface of the U-shaped short frame 53, the two L-shaped rods 56 are fixed on the left and right sides of the U-shaped short frame 53, the baffle 57 is fixed on the front of the two L-shaped rods 56, and the back of the baffle 57 is fixedly connected to the front of the two square blocks 55. The baffle 57 is located in front of the operating table 1. When the baffle 57 moves downward, the baffle 57 moves to the front of the operating table 1, so that when the equipment is performing pressure detection, the squeezed magnetostrictive sensor fragments will not splash onto the staff, prevent the magnetostrictive sensor fragments from splashing forward when the equipment is in use, and avoid the magnetostrictive sensor fragments from splashing when the detection device is in use. Injury to the staff.

[0041] The top surface of the shell compression device 5 is provided with an anti-breaking device 6, which includes a rectangular plate 61, a cylinder 62, a spring 63, a sliding column 64 and an arc plate 65. The rectangular plate 61 is fixed on the top surfaces of the two square blocks 55, the rectangular plate 61 is located on the back of the U-shaped short frame 53, the cylinder 62 passes through and is fixed in the middle of the top surface of the rectangular plate 61, the spring 63 is fixed on the top of the cylinder 62, the sliding column 64 is fixed on the end of the spring 63 away from the cylinder 62, the outer wall of the sliding column 64 is slidably connected with the inner wall of the cylinder 62, and the arc plate 65 is fixed on the bottom surface of the sliding column 64. The sensor rod on the heightening plate 3 is on the movement trajectory of the arc plate 65. Under the action of the extrusion force, the arc plate 65 squeezes the connection between the magnetostrictive sensor housing and the long rod, so that the connection between the magnetostrictive sensor housing and the long rod will not break under the action of stress, so as to avoid the poor detection effect caused by the breakage of the connection between the magnetostrictive sensor housing and the long rod when the detection device is in use.

[0042] The anti-break device 6 also includes two Y-shaped rods 66, two U-shaped thin frames 67 and two shaft plates 68.

The bottom surfaces of the two shaft plates 68 are set to be arc-shaped, and the top surface of the operating table 1 is on the movement trajectory of the two shaft plates 68. The two shaft plates 68 are blocked on both sides of the U-shaped short frame 53 in an eight-shaped shape, so that when the device detects the magnetostrictive sensor housing, the parts of the magnetostrictive sensor housing will not burst out to both sides, so as to avoid the magnetostrictive sensor housing being broken and ejected when the detection device is in use, causing danger to the surrounding of the detection device.

[0043] When the strip plate 10 drives the double-hole plate 12 to move downward, the double-hole plate 12 drives the Z-shaped reinforcing rod 51 to move downward, and the Z-shaped reinforcing rod 51 drives the double-ring frame 52 to move downward. At the same time, the Z-shaped reinforcing rod 51 drives the U-shaped short frame 53 to move downward, and the U-shaped short frame 53 drives the pressing block 54 to move downward. In the process of the pressing block 54 moving downward, the pressing block 54 contacts the magnetostrictive sensor housing, and the pressing block 54 applies pressure to the magnetostrictive sensor housing. At the same time, the double-ring frame 52 supports the Z-shaped reinforcing rod 51, so that the pressing block 54 squeezes the magnetostrictive sensor housing, so that the equipment can simultaneously detect the pressure resistance of the magnetostrictive sensor housing during detection, thereby preventing the equipment from being unable to simultaneously detect the pressure resistance of the magnetostrictive sensor housing when in use, thereby avoiding the problem that the detection device cannot simultaneously detect the pressure resistance of the magnetostrictive sensor housing when in use, resulting in a single and incomplete detection effect of the equipment.

[0044] While the Z-shaped reinforcing rod 51 drives the U-shaped short frame 53 to move downward, the U-shaped short frame 53 drives the square bar 55 to move downward, the U-shaped short frame 53 drives the L-shaped rod 56 to move downward, and the L-shaped rod 56 drives the baffle 57 to move downward, so that during the downward movement of the baffle 57, the baffle 57 moves to the front of the operating table 1, so that when the equipment is performing pressure detection, the squeezed magnetostrictive sensor fragments will not splash onto the staff, and the magnetostrictive sensor fragments are prevented from splashing forward when the equipment is in use, thereby avoiding the problem of injuries to the staff caused by the sputtering of the magnetostrictive sensor fragments when the detection device is in use.

In the process of the arc plate 65 moving downward, the arc plate 65 contacts the long rod of the magnetostrictive sensor. Under the action of the extrusion force, the arc plate 65 squeezes the connection between the magnetostrictive sensor housing and the long rod, so that the connection between the magnetostrictive sensor housing and the long rod will not break under the action of stress, thereby avoiding the problem of poor detection effect caused by the breakage of the connection between the magnetostrictive sensor housing and the long rod when the detection device is in use.

[0046] When the square block 55 drives the rectangular plate 61 to move downward, the rectangular plate 61 drives the Y-shaped rod 66 to move downward, the Y-shaped rod 66 drives the U-shaped thin frame 67 to move downward, and the U-shaped thin frame 67 drives the shaft plate 68 to move downward. In the process of the shaft plate 68 moving downward, the shaft plate 68 contacts the operating table 1. Under the action of the squeezing force, the shaft plate 68 rotates in the U-shaped thin frame 67, so that the two shaft plates 68 are blocked on both sides of the U-shaped short frame 53 in an eight-shaped shape, so that when the device detects the magnetostrictive sensor housing, the parts of the magnetostrictive sensor housing will not be ejected to both sides, so as to prevent the parts of the magnetostrictive sensor housing from being ejected from the device when the device is in use, thereby avoiding the problem that the magnetostrictive sensor housing is broken and ejected when the detection device is in use, causing danger to the surrounding of the detection device.
