Description

Technical Field

[0001] The invention relates to the technical field of medical accelerator equipment, and in particular to a braking and anti-collision device of an accelerator treatment bed. Background Art

[0002] Medical linear accelerators can generate photon rays and electron rays. They input high-voltage AC voltage, which is triggered by the output signal of the control system circuit to accelerate the electrons emitted by the electron gun. After a series of operations, the control circuit outputs a signal to adjust the electron emission rate of the electron gun to achieve the required and stable dose rate, thereby generating energy to kill cancer cells. Therefore, it is often used in cancer treatment. A simple electron linear accelerator must at least include an acceleration place (acceleration tube), a high-power microwave source and waveguide system, a control system, and a ray leveling and protection system. In use, the treatment bed is accurately positioned through a rotating body. During the rotation process, most current linear accelerators often use manual release of the brake (brake brake) operation during treatment positioning to shorten the positioning time. However, due to the rearward position of the bed limit block, during operation, the treatment bed often moves in the T direction and hits the brake, causing the screws fixing the brake to break, and the treatment work can no longer be carried out.

DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should belong to the scope of protection of the present invention.

[0026] like Figure 1 to Figure 3 As shown, the present invention relates to a braking and anti-collision device for an accelerator treatment bed, comprising a bed bottom plate 1, a treatment bed 5, a limit block 8, an anti-collision bolt 9 and an anti-collision alarm mechanism.

[0027] The treatment bed 5 is arranged on the bed base 1. A right-angle setting area is provided at the end of the bed base 1, and a first slide rail 2 is fixed on the area. A right-angle fixing area 101 for fixing the limit block 8 is provided at the edge of the bed base 1, and the width of the area is 1 cm. A sliding groove 4 is provided on the first slide rail 2, and a limit hole 3 for connecting with the limit block 8 is provided at the outer end of the first slide rail 2. The width dimension of the limit block 8 matches the dimension of the right-angle fixing area 101, and the limit block 8 is provided with an anti-collision protrusion 801 in the direction of the treatment bed 5, which is used to withstand the impact of the treatment bed 5 and achieve the stability of the bed body. A mounting hole 802 is also provided in the central position of the limit block 8, and a fixing screw 803 is installed on the mounting hole 802, and the size of the fixing screw 803 matches the size and position of the limit hole 3. Shockproof pads are provided on each surface of the limit block 8.

[0028] A second slide rail 6 is provided at the edge of the treatment bed 5 corresponding to the right-angle setting area. The second slide rail 6 is provided with a protruding slider 7 matching the slide groove 4 of the first slide rail 2, so that the treatment bed 5 can slide on the bed bottom plate 1.

[0029] An anti-collision groove 11 is provided at the edge of the plane where the bed bottom plate 1 contacts the treatment bed 5, and a brake and an anti-collision alarm mechanism are installed in the anti-collision groove 11. The brake and the anti-collision alarm mechanism are fixed by two anti-collision bolts 9. The anti-collision bolts 9 are preferably M7*10 bolts. The M7*10 bolts have high strength and can prevent the bolts from being broken due to the collision of the treatment bed 5, thereby avoiding damage to the brakes, ensuring that there will be no mechanical problems in the GT direction of the treatment bed 5, and greatly reducing the problem of downtime caused by failures.

[0030] The anti-collision alarm mechanism includes a distance sensor 10, a controller, a warning light 12, and a sound alarm 13. The distance sensor 10 is connected to the controller, and the controller is connected to the warning light 12 and the sound alarm 13 respectively, so as to give a warning alarm by sensing the distance of the treatment bed 5. The maximum height of the distance sensor 10, the controller, the warning light 12, and the sound alarm 13 does not exceed the depth of the anti-collision groove 11, so as to achieve barrier-free passage of the treatment bed 5. When the distance sensor 10 senses that the treatment bed 5 is approaching, a sound reminder or a light reminder can be given in advance before the treatment bed 5 collides with the brake parts, so as to further prevent the treatment bed from colliding with the brake parts and reduce the problems caused by the collision.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
