Abstract
The utility model relates to an X-ray device, specifically to a photograph meshing movement braking rail unit for an X-ray device. The photograph meshing movement braking rail unit comprises a box body, a cassette tackle arranged in the box body and a transmission device arranged in the box body, and is characterized in that the transmission device comprises a linear guide rail consisting of an upper rail and a lower rail; the cassette tackle is arranged on the upper rail; the upper rail is provided with grooves corresponding to the two sides of the connecting part of the lower rail; brake blocks for preventing the cassette tackle from moving are arranged inside the grooves; arc-shaped bump structures on sides of the brake blocks contact with the side walls of the grooves; a gap exists between the two sides of the arc-shaped bump structures and the side walls of the grooves; the brake blocks contact with the lower rail; and an oil hole on the surface of the upper rail is communicated with the side walls of the grooves. Compared with the prior art, the photograph meshing movement braking rail unit for the X-ray device is low in cost, simple in structure, and accurate in positioning.
Description
[technical field]
This utility model relates to a kind of X-ray equipment, and a kind of specifically X-ray equipment is taken the photograph sheet lattice motion braking orbit device.
[background technology]
Using medical X-ray equipment; Need to make film, carries out load by manual work earlier before using, the magazine of film making usefulness is placed on the magazine coaster that runs the sheet control device the check point of human body; And send into ready position, control magazine through control system then and move to exposure position.Existing X-ray equipment runs the sheet control system, generally adopts the alternating current generator belt wheel to carry out transmission, needs to increase the optocoupler positioner, and cost is high; Perhaps adopt direct current generator, the eddy current worm speed-down case of band two ends output shaft, an end is exported with synchronous pulley; One end fixed gear; Drive the potentiometer transmission, calculate the displacement of magazine coaster, equally also have cost height, complicated circuit and the lower deficiency of control accuracy.
[summary of the invention]
This utility model has overcome the deficiency of prior art, provides a kind of simple in structure, and driving is accurate, little, the easy to operate X-ray equipment of volume is taken the photograph sheet lattice motion braking orbit device.
To achieve these goals, this utility model has designed a kind of X-ray equipment and has taken the photograph sheet lattice motion braking orbit device, comprises casing; Place the intravital magazine coaster of case; And place the intravital actuating device of case, it is characterized in that: actuating device comprises the line slideway of being made up of last rail and following rail, and last rail is provided with the magazine coaster; The both sides of the junction of rail are provided with groove under the last rail correspondence; Be provided with the brake block that prevents that the magazine coaster from moving in the groove, brake block one side is that the arcuation bulge-structure contacts with the sidewall of groove, and there are the space in the both sides of arcuation bulge-structure and the sidewall of groove; Brake block contacts with following rail; Last track surface also is provided with oilhole and communicates with the sidewall of groove.
Said brake block is provided with metal hard-sealing with the contact position of following rail.
The rubbing surface of described brake block and groove is provided with the metal sealing.
This utility model is compared with prior art, and is with low cost, simple in structure, accurate positioning.

Referring to Fig. 1 to Fig. 5,1 is casing; 2 is the magazine coaster; 3 is actuating device; 4 is last rail; 5 are following rail; 6 is groove; 7 is brake block; 8 is bulge-structure; 9 is metal hard-sealing; 10 are the metal sealing; 11 is oilhole; 12 is hydraulic oil.
[specific embodiment]
Below in conjunction with accompanying drawing this utility model is further described.
To shown in Figure 4, the X-ray equipment of this utility model is taken the photograph sheet lattice motion braking orbit device and is comprised casing 1 like Fig. 1, places the magazine coaster 2 in the casing 1, and the actuating device 3 that places casing interior 1.Actuating device comprises the line slideway of being made up of last rail 4 and following rail 5, and last rail 4 is provided with magazine coaster 2, and the last rail 4 corresponding both sides of the junction of rail 5 down are provided with groove 6, is provided with in the groove 6 to be used to prevent that the brake block 7 that magazine coaster 2 runs sheet from contacting with following rail 5; Last rail 4 surfaces also are provided with oilhole 11 and communicate with the sidewall of groove 6.Brake block 7 one sides are that arcuation bulge-structure 8 contacts with the sidewall of groove 6, and the arcuation bulge-structure contacts for point with the sidewall of groove, and the contact of phase specific surface can better be played a supporting role; Because of the face contact maybe be after long-time the use; Because of the relation of frictional force, the surface may produce wearing and tearing, causes surface irregularity; The sidewall of groove can't carry out reliable supporting to back-up block, adopts the arcuation bulge-structure to avoid the generation of this situation.There is the space that is used to fill hydraulic oil in the sidewall of the both sides of arcuation bulge-structure 8 and groove 6.Brake block 7 is provided with metal hard-sealing 9 with the contact position of following rail 5, and brake block 7 is provided with metal sealing 10 with the rubbing surface of groove 6.
As shown in Figure 5, during work, hydraulic oil 12 is sent through oil pump in the groove 6 of as above rail 4, brake block 7 is under the pressure effect of hydraulic oil 12, and the both sides of rail 5 apply active force downwards, thereby realize arresting purpose.
This utility model is compared with prior art, adopts rectilinear orbit as actuating device, and brake block is set in orbit, and not only simple in structure, cost is low, and accurate positioning.
