As is preferable in the present embodiment, the guide groove assembly 3 includes: the anti-falling metal plate forming machine comprises a guide groove 10, rollers 11 and an anti-falling metal plate 12, wherein the rollers 11 are rotatably connected in the guide groove 10, and the anti-falling metal plate 12 is arranged on the guide groove 10; the guide groove 10 is used for the roller 11 to rotate in, the roller 11 is used for the collimator to slide on, and the anti-falling sheet metal 12 has the function of preventing the collimator from falling; collimators may be placed by the channel assemblies 3.

From the above description, it can be seen that the following technical effects are achieved by the present application:

in the embodiment of the application, a plurality of pairs of guide groove assemblies 3 are arranged, and the guide groove assemblies 2 are arranged at the bottom of the first frame body 1 through the first frame body 1; the two pairs of guide groove assemblies 3 are arranged at the top of the first frame body 1 and are used for matching the two pairs of collimators; the collimator to be replaced is placed through one pair of guide groove assemblies 3, and the collimator to be dismounted is placed through the other pair of guide groove assemblies 3; the collimator car moving device achieves the purposes of reducing the assembling and disassembling times of the collimator and the moving times of the collimator car, thereby saving the time and labor for replacing the collimator, improving the technical effect of replacing efficiency, and further solving the technical problems of time consumption, labor consumption and low efficiency in the collimator replacing process.

Preferably, in this embodiment, the method further includes: the second support body 6 of setting at 1 top of first support body, and set up and be in deflector 7 on the second support body 6, the downside of deflector 7 arrange with two just right pairs of gib block 8 of guide slot subassembly 3. In order to ensure the position of the collimator on the collimator car, the top of the collimator needs to be guided so that the collimator does not deviate from the correct position; thus, two pairs of guide strips 8 are arranged directly opposite the channel assembly 3, enabling the collimator to be held in the correct position.

Preferably, in this embodiment, the method further includes: an adjustable angle plate 9 is arranged on the guide plate 7. The angle can be adjusted.

Preferably, in this embodiment, the method further includes: a manual release mechanism 13 and a pedal mechanism 14, wherein the manual release mechanism 13 is detachably connected with the pedal mechanism 14, and the manual release mechanism 13 is detachably connected with the guide groove assembly 3. Preferably, in this embodiment, the manual release mechanism 13 includes: optical axis 15, stopper 16, pressure spring 17 and spherical handle 18, stopper 16 cover is in on the optical axis 15, pressure spring 17 cover be in on the optical axis 15, and with stopper 16 links to each other, spherical handle 18 sets up the top of optical axis 15. Preferably, in this embodiment, the pedal mechanism 14 includes: the safety device comprises a pedal pin assembly 19, a safety ejector rod 20 connected with the pedal pin assembly 19, a guide rod spring 21 connected with the safety ejector rod 20, a left guide rod 22 and a right guide rod 23 connected with the guide rod spring 21, and limit pins 24 arranged on the left guide rod 22 and the right guide rod 23. Preferably, in this embodiment, the pedal mechanism 14 further includes: the pedal assembly 25 is connected with the safety mandril 20 and is connected with the pedal pin assembly 19, and the guide rail slider group 26 is connected with the left guide rod 22 and the right guide rod 23 in a sliding way.

When the foot pin assembly 19 of the collimator vehicle is not depressed, the left guide rod 22 and the right guide rod 23 have an axial limiting effect on the optical axis 15 under the support of the safety ejector rod 20. At this time, the optical axis 15 cannot move, and the collimator is locked by the limiting block 16, so that the limiting effect on the collimator is achieved. When the collimator car member foot pin assembly 19 is depressed and the knob 18 is not depressed, the collimator is also locked by the stop block 16. Only when the foot pin assembly 19 of the collimator vehicle is stepped down and the spherical handle 18 is pressed down, the collimator can be unlocked by the limiting block 16, and the collimator can freely slide on the collimator vehicle. The secondary protection is realized, and the collimator is effectively prevented from generating displacement in multiple directions when in use to influence detection.

When the pedal pin assembly 19 is depressed, the pedal pin assembly 19 moves the safety ram 20 downward. So that the left and right guide bars 22 and 23 are moved to the middle position by the guide bar tension spring. And under the restriction of the limit pin 24, the left guide rod 22 and the right guide rod 23 cancel the axial restriction of the optical axis 15.

When the collimator needs to be locked, the pedal is stepped down, so that the safety ejector rod 20 automatically rises to a free position under the action of the elastic force of the pedal. At this time, the left guide rod 22 and the right guide rod 23 slide along the guide rail slider group 26 of the member 37 to both sides under the guidance of the inclined surface of the safety lever 20, so that the left guide rod 22 and the right guide rod 23 restore the axial restriction of the optical axis 15.

The optical axis 15, the limiting block 16 and the spherical handle 18 are connected together, and when the spherical handle 18 is pressed down manually, the limiting block 16 moves downwards along with the optical axis 15, so that the limiting block 16 loses the limiting effect on the collimator. When the spherical handle 18 is released, the limiting block 16 is reset along with the optical axis 15 under the action of the pressure spring 17; the limit on the collimator is restored.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
