[0030] This utility model embodiment provides an automatically adjustable gradient coil mounting fixture.

[0031] Please see Figures 1-6 The forklift 1, electrical control cabinet 7, flash meter 8, lifting motor, electric push rod 503 and electro-hydraulic push rod 604 involved in this application are all prior art, and will not be described in detail in this application.

[0032] The device includes a forklift 1, an electrical control cabinet 7 fixedly mounted externally on the forklift 1, and flash measuring instruments 8 fixedly mounted on the top surfaces of both the forklift 1 and the lifting platform 401. The electrical control cabinet 7 can control the operation of each electrical component inside the device, and the flash measuring instruments 8 can automatically position and measure the shape of the workpiece. The two flash measuring instruments 8 can respectively position and measure the size and position of the installation space of the gradient coil and the magnet, and transmit the measurement data to the calculation and control module inside the electrical control cabinet 7, so that the electrical control cabinet 7 can automatically adjust the position of the gradient coil according to the measurement data, which is convenient for the installation of the gradient coil.

[0033] The mounting forklift 1 is externally equipped with a mounting strut 2, which has two support mechanisms 3. The mounting strut 2 can lift the gradient coil and place it inside the magnet using the mounting forklift 1, greatly reducing the workload of manual coil installation. The support mechanisms 3 can reduce the wear on the inner wall of the coil during installation and improve the service life of the gradient coil.

[0034] The support mechanism 3 includes a support frame 301 fixedly connected to the mounting strut 2. A fixing clip 302 is fixedly connected to the outer surface of the support frame 301. The support frame 301 and the fixing clip 302 can provide support and stability for the arc plate 303, so that when the mounting strut 2 lifts the coil, the arc plate 303 can support the coil. The top of the arc plate 303 has a certain curvature, which can increase the contact area between the mounting strut 2 and the coil, increase the support stability of the mounting strut 2 for the coil, and reduce the wear on the inner wall of the coil.

[0035] An arc-shaped plate 303 is fixedly connected inside the fixing clamp 302. A plastic pad 304 is fixedly connected to the surface of the arc-shaped plate 303. The plastic pad 304 can increase the friction between the arc-shaped plate 303 and the coil, prevent the coil from sliding on the mounting support rod 2 when it is lifted, and also protect the coil, avoiding damage to the inner wall of the coil by the mounting support rod 2 during the installation of the coil.

[0036] A lifting adjustment mechanism 4, a horizontal adjustment mechanism 5, and an elevation adjustment mechanism 6 are provided between the forklift 1 and the mounting support 2. Through the setting of the lifting adjustment mechanism 4, the horizontal adjustment mechanism 5, and the elevation adjustment mechanism 6, the device can automatically adjust the position of the coil according to the position information measured by the flash detector 8, which meets the adjustment requirements of the coil in four degrees of freedom (X, Y, Z, and R) and improves the convenience of coil installation.

[0037] The lifting adjustment mechanism 4 includes a lifting plate 401, with a threaded block 402 fixedly connected to the outer surface of the lifting plate 401. A threaded lifting rod 403 is rotatably connected inside the mounting forklift 1. The threaded block 402 meshes with the threaded lifting rod 403. A lifting motor is fixedly installed on the top surface of the mounting forklift 1. The threaded lifting rod 403 is fixedly connected to the output shaft of the lifting motor. When the motor starts, the threaded lifting rod 403 will rotate with the motor shaft. The rotation of the threaded lifting rod 403 can drive the threaded block 402 to rise and fall, thereby driving the lifting plate 401 to rise and fall, which facilitates the device to adjust the height of the mounting support rod 2, thereby changing the installation height of the coil.

[0038] A locking block 404 is fixedly connected to the outer surface of the lifting plate 401. A slot 405 is opened on the outer surface of the mounting forklift 1. The locking block 404 slides inside the slot 405. Both the locking block 404 and the slot 405 are cross-shaped designs, which can make the lifting plate 401 maintain sufficient stability during the lifting process and improve the lifting stability of the mounting support rod 2.

[0039] The horizontal adjustment mechanism 5 includes a horizontal plate 501, a sliding block 502 fixedly connected to the outer surface of the horizontal plate 501, and an electric push rod 503 fixedly installed on the surface of the lifting plate 401. The telescopic end of the electric push rod 503 is fixedly connected to the sliding block 502. The surface of the lifting plate 401 is provided with a groove that matches the sliding block 502. When the electric push rod 503 receives the position adjustment information from the electrical control cabinet 7, the electric push rod 503 can push the sliding block 502 to slide inside the groove. The sliding of the sliding block 502 can drive the horizontal plate 501 to slide outside the lifting plate 401, thereby adjusting the horizontal position of the mounting support rod 2 and facilitating the adjustment of the coil's horizontal position.

[0040] A biting strip 504 is fixedly connected to the outer surface of the horizontal plate 501, and a support strip 505 is fixedly connected to the outer surface of the lifting plate 401. The biting strip 504 and the support strip 505 are slidably connected. The support strip 505 has biting grooves on both sides, and the biting strip 504 has biting teeth on both sides. When the biting strip 504 and the support strip 505 are engaged, the biting strip 504 can maintain stable sliding on the surface of the support strip 505, thereby improving the sliding stability of the horizontal plate 501.

[0041] The elevation adjustment mechanism 6 includes an adjustment plate 601. The mounting support rod 2 is fixedly connected to the adjustment plate 601. When the adjustment plate 601 changes position under the drive of the lifting adjustment mechanism 4 and the horizontal adjustment mechanism 5, the adjustment plate 601 can drive the mounting support rod 2 to change position, thereby adjusting the installation angle of the coil on the mounting support rod 2. This makes it convenient for the device to install the gradient coil into various magnets, increasing the ease of coil installation and improving the applicability of the device.

[0042] A connecting rod 602 is fixedly connected to the outer surface of the horizontal plate 501. The adjusting plate 601 is rotatably connected to the connecting rod 602. The connecting rod 602 can provide a fulcrum for the angle adjustment of the adjusting plate 601, so that the adjusting plate 601 can change the elevation angle of the mounting support rod 2 during the rotation of the adjusting plate 601 with the connecting rod 602 as the fulcrum, thereby adjusting the installation angle of the coil.

[0043] An adjustment groove 603 is provided at the bottom of the adjustment plate 601. An electro-hydraulic actuator 604 is fixedly installed inside the horizontal plate 501. A sliding support rod 605 is fixedly connected to the telescopic end of the electro-hydraulic actuator 604. The sliding support rod 605 is slidably connected to the adjustment groove 603. When the electro-hydraulic actuator 604 receives the horn adjustment signal from the electrical control cabinet 7, the electro-hydraulic actuator 604 can extend and retract to push the sliding support rod 605. The movement of the sliding support rod 605 will drive the bottom of the adjustment plate 601 to rotate under the limit of the adjustment groove 603, thereby adjusting the angle of the adjustment plate 601. The adjustment groove 603 provides space for the electro-hydraulic actuator 604 to push the adjustment plate 601 to rotate, avoiding motion interference. At the same time, the adjustment groove 603 can also improve the sliding stability of the sliding support rod 605 and improve the stability of the device's adjustment angle.

[0044] Working principle: The operator first controls the lifting and lowering of the mounting support rod 2 via the electrical control cabinet 7, enabling the support rod 2 to lift the gradient coil. Then, the device is pushed to a suitable position close to the magnet. Next, the electrical components in the device are activated. Two flash meters 8 locate and measure the installation space of the gradient coil and magnet, transmitting the measurement information to the electrical control cabinet 7. The electrical control cabinet 7 calculates the required adjustment angle for the coil based on this information, and then controls the operation of the lifting adjustment mechanism 4, the horizontal adjustment mechanism 5, and the elevation adjustment mechanism 6 accordingly. When the motor starts, it drives the threaded lifting rod 403 to rotate, which in turn drives the lifting plate 401 to rise and fall via the threaded block 402, thereby adjusting the installation height of the coil. When the electric push rod 503 starts, it drives the horizontal plate 501 to slide horizontally on the lifting plate 401 via the sliding block 502, thereby adjusting the horizontal position of the coil. When the electro-hydraulic push rod 604 starts, it drives the bottom end of the adjusting plate 601 to rotate via the adjusting groove 603 and the sliding support rod 605, thereby adjusting the elevation angle of the coil. This facilitates the automatic adjustment of the gradient coil installation angle and greatly reduces the workload of coil installation.
