Abstract
The utility model relates to an anti-collision device of a radiotherapy analogue machine collimator, which is provided with an anti-collision big circle suitable for the collimator provided with a connecting rod, the upper end of the connecting rod is designed with a contact touch piece, the connecting rod is provided with a spacing adjusting spring and the contact touch piece of the connecting rod corresponds to a move spacing switch of the collimator. The utility model has the advantages that structure is simple and reasonable, object contact conditions can be sensed in an omnibearing mode and operation is sensitive and quick. An operating machine frame is stopped in time when the machine frame touches objects, the equipment and personal safety are protected and safety is high.
Description
Technical field
This utility model relates to a kind of anticollision device of radiotherapy simulator collimator, is fitted on the radiotherapy simulator collimator to use.
Background technology
In radiotherapy simulator utilization and operation process; the analog machine collimator need move up and down; or the analog machine frame rotates; be the patient who prevents that collimator from running into object or doing to treat; a device must be arranged; frame is stopped, the intact and personal safety of protection equipment with object collision the time.
Summary of the invention
The purpose of this utility model is to provide a kind of anticollision device of radiotherapy simulator collimator, and the frame of operation is stopped when running into object, and is safe and reliable.
The anticollision device of radiotherapy simulator collimator described in the utility model, the anti-collision great circle that adapts with collimator is arranged, the anti-collision great circle is provided with connecting rod, part is bumped in the upper end design contact of connecting rod, connecting rod is provided with spacing regulating spring, and it is corresponding with the mobile limit switch of collimator that part is bumped in the contact of connecting rod.
In equipment running process; when object comprises human body contact anti-collision great circle; connecting rod can bump part to contact with force transmission; make contact bump the mobile limit switch that part touches collimator; thereby the relay in the circuits for triggering; make frame or collimator stop motion in the motion, safe and reliable, protected equipment and personal safety.
The anti-collision great circle is the U-shaped structure of sealing, and is simple in structure, better with the adaptation situation of collimator.
The mobile limit switch of collimator is designed to 4, thereby realizes comprehensive protection, can respond to the contact-impact of front, rear, left and right all directions simultaneously.Adopt connecting rod and contact this connected mode of bumping part, make the collision that comes from other directions all become contact and bump moving up and down of part, make it and the limit switch collision, play the anti-collision effect.
In this utility model:
Spring is under the compressed state always, only keeps very little pretightning force,, can play a role as long as be subjected to very little collision.The thickness of spacing regulating spring, length, coiling diameter design as the case may be, make elastic force suitable.
The anti-collision great circle bends molding by light-duty tubing, and welding is made, and certain intensity is arranged, and tube wall is thinner, lighter weight, and the surface prevents to get rusty through chemical treatment.
This utility model is simple and reasonable, can contact situation by comprehensive sense object, and is fast sensitive, and the frame of operation is in time stopped when running into object, protected equipment and personal safety, safe and reliable.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Fig. 2, anti-collision great circle structural representation.
Among the figure: 1, part 5, limit switch 6, fixture 7, collimator are bumped in anti-collision great circle 2, connecting rod 3, spacing regulating spring 4, contact.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, the anticollision device of radiotherapy simulator collimator described in the utility model, the anti-collision great circle 1 that is sealing U-shaped structure that adapts with collimator 7 is arranged, anti-collision great circle 1 is provided with connecting rod 2, part 4 is bumped in the upper end design contact of connecting rod 2, connecting rod 2 is provided with spacing regulating spring 3, and it is corresponding with the mobile limit switch 5 of collimator 7 that part 4 is bumped in the contact of connecting rod 2, and limit switch has 4.
Operation principle:
When object or patient and 1 collision of anti-collision circle, regulating spring 3 is extruded, and connecting rod 2 drives to contact to bump on the part 4 and moves; making contact bump part 4 contacts with limit switch 5; the relay effect that limit switch 5 touches in the circuit stops the motion of collimator 7 or frame, thereby plays a protective role.Maybe will treat patient and remove when taking knocked object away, knocked object or patient and anti-collision great circle 1 break away from, and under the effect of regulating spring 3, connecting rod 2 drives contact and bumps part 4 and separate with limit switch 5, and at this moment, collimator or frame can continue motion again.
