Abstract
The utility model discloses a lifting mechanism for a therapeutic bed. A diagonal plane of a base is fixedly and downwards installed below the ground, and a bulge block at one lateral face of a large rectangular of the base is provided with a nut; both sides of the plane of the large rectangular of a trailing bar are respectively and longitudinally provided with a guide rail, and the guide rails and guide rail frames arranged at both sides of the lateral face of the large rectangular of the base form a guide rail pair; a screw rod in the trailing bar are vertically installed on a bearing with two ends, and the screw rod and the nut form a screw rod pair; one end of the screw rod, which is exposed outside the trailing bar, is provided with a band wheel, and a rotating mechanism is composed of the band wheel and a bmotor by a synchronous belt; when the screw rod is rotated, the trailing bar is driven to carry out upwards and downwards vertical sliding along the guide rail pair at the lateral face of the large rectangular of the base. Because the lifting mechanism of the therapeutic bed uses the guide rails and the screw rod to carry out transmission, the positioning accuracy of vertical motions can reach a range within 0.05MM, and the lifting range can be larger than 1.5 M. The treatment bed adopts a sinking type structure, and the space occupancy is very small.
Description
Technical field
This utility model relates to the therapeutic bed of gamma ray therapeutic apparatus, especially relates to a kind of therapeutic bed elevating mechanism.
Background technology
The therapeutic bed of gamma ray therapeutic apparatus generally has only the motion mode of plane coordinates axle (as X-axis and Y-axis).In order to enlarge the therapeutic domain of equipment, therapeutic bed needs the motion of a kind of vertical lift (Z axle), and wish that range is bigger, motion the time has higher each to precision.At present, shear mechanism or double-deck multiplication mechanism are generally adopted in the Z axle lifting of gamma-ray therapeutic bed.Two pole decussations of shear mechanism therapeutic bed, the cross point maintains static the fulcrum as two pole shearing motions, and the pole upper end is connected by the therapeutic bed of sliding bearing and its support.During the pole shearing motion, the pole angle becomes big or diminishes, and the vertical dimension of pole upper end and fulcrum diminishes or becomes big, thereby realizes the elevating movement of therapeutic bed with respect to fulcrum.There is transformational relation in this mechanism simple in structure between the angular movement of pole and the rectilinear motion of therapeutic bed, makes the rigidity of shear mechanism therapeutic bed relatively poor, and precision is relatively poor, and the stroke that moves both vertically is very little.
Summary of the invention
The purpose of this utility model is to provide a kind of elevating mechanism of the therapeutic bed of using for gamma ray therapeutic apparatus, and its adopts guide rail lead screw transmission, and movement travel is big, precision is high.
The technical scheme that its technical problem that solves this utility model adopts is:
Comprise: base, nut, guide rail bracket, guide rail, screw mandrel, planker, motor, band and belt wheel synchronously.The fixed installation that flats down of cutting sth. askew of base, the relative planar horizontal in plane of cutting sth. askew locates below ground level, on the large rectangle one lateral projecting block of base nut is housed, a guide rail is vertically respectively installed in the both sides, large rectangle plane of planker, and the guide rail bracket of guide rail and the both sides, large rectangle side that are installed in base is formed guideway; Planker is inner to have a rhizoid bar to be vertically mounted on the bearings at both ends near place, large rectangle plane, and screw mandrel and the nut that is installed on the base projecting block are formed screw pair; Screw mandrel exposes an end of planker belt wheel is installed, and forms rotating mechanism by synchronous band and the motor that is installed in planker inside; Screw mandrel rotates the drive planker and can do vertically to slide up and down along the lateral guideway of the large rectangle of base, make the therapeutic bed that is installed in above the planker make Z axle vertical displacement movement.
The useful effect that the utlity model has is:
1. adopt accurate ball-screw transmission, guideway engagement sliding type, no-float, motion steadily, the vertical motion positions precision of therapeutic bed can reach in 0.05 millimeter, range can be greater than 1.5 meters;
2. employing sinkage type structure, the volume that vertically takies of therapeutic bed becomes below ground.At ordinary times, therapeutic bed is positioned at ground with top only Y-axis motion parts and bed panel, and order sense space occupancy is very little.
Description of drawings
Accompanying drawing is a longitudinal profile structural representation of the present utility model.
Among the figure: 1-base, 2-nut, 3-guide rail bracket, 4-guide rail, 5-screw mandrel, 6-planker, 7-motor, 8-are with synchronously, the 9-belt wheel.
The specific embodiment
As shown in drawings, this utility model comprises: base 1, nut 2, guide rail bracket 3, guide rail 4, screw mandrel 5, planker 6, motor 7, be with 8 and belt wheel 9 synchronously.The fixed installation that flats down of cutting sth. askew of base 1, the relative planar horizontal in plane of cutting sth. askew locate below ground level (0 line in the accompanying drawing following), on the large rectangle one lateral projecting block of base 1 nut 2 is housed, a guide rail 4 is vertically respectively installed in the both sides, large rectangle plane of planker 6, and the guide rail bracket 3 of guide rail 4 and the both sides, large rectangle side that are installed in base 1 is formed guideways; Place, planker 6 inner close large rectangle plane has a rhizoid bar 5 to be vertically mounted on the bearings at both ends, and screw mandrel 5 and the nut 2 that is installed on base 1 projecting block are formed screw pairs; Screw mandrel 5 exposes an end of planker 6 belt wheel 9 is installed, by forming rotating mechanisms with 8 with the motor 7 that is installed in planker 6 inside synchronously; Screw mandrel 5 rotates drive planker 6 and can do vertically to slide up and down along the lateral guideway of the large rectangle of base 1, make the therapeutic bed that are installed in above the planker 6 make Z axle vertical displacement movement.
Guideway and screw pair all adopt the Digit Control Machine Tool sophisticated product, and not only length can be done very longly, and the vertical lift scope that realizes therapeutic bed is greater than 1.5 meters, and precision also can be accomplished very high.Adopting accuracy class is not very high level Four product, and the precision of screw pair can guarantee that more than 0.04 millimeter, the precision of guideway can guarantee more than 0.03 millimeter.In addition reasonably design and manufacturing process, the vertical motion positions precision of therapeutic bed can guarantee in 0.05 millimeter.
The above-mentioned specific embodiment is used for this utility model of explaining; rather than this utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to this utility model is made all fall into protection domain of the present utility model.
