Abstract
The utility model discloses a walking control device for a medical mobile X-ray set, and belongs to the technical field of medical instruments. The walking control device is characterized in that a handle component (12) is pushed by hands; a connecting rod (6) and a roller shaft (5) are driven by a driving shaft (7) to slide in a sliding seat (4); a small gear ring of a sector wheel (2) is meshed with an upper fixed rack (1); when the connecting rod (6) slides, a large gear ring of the sector wheel (2) stirs a rack bar (3), so that the rack bar (3) slides in a linear bearing (9) to drive the potential change of a potentiometer in a potentiometer component (8), start a driving motor and enable the medical mobile X-ray set to move forwards; and when the handle component (12) is released, the rack bar (3) is reset under the coaction of a resetting spring and a compression spring (10) of the potentiometer, and the driving motor stops. The rack bar (3) can be accurately reset by regulating a thread bushing (11) and the elasticity of the compression spring (10). The walking control device has the advantages of simple structure, convenience for mounting, resetting accuracy, resetting force adjustability and low cost.
Description
Technical field
This utility model belongs to technical field of medical instruments.
Background technology
The type of drive of existing mobile X-ray unit running gear roughly is divided into two kinds: people's force urges and motor-driven.Continuous development along with the medical X-ray technology; Medical X ray machine is digitized, function synthesizedization, hommization more and more; The synthesization of function must make the quality of complete machine increase; And the mode of people's force urges can not satisfy the needs of medical X ray machine development gradually only for being used for the lighter small-sized machine of weight.Electric walking has become a kind of Development Trend.Convenient, flexible traveling control device becomes an important goal of the medical mobile X-ray unit of electric walking.
Existing homemade medical mobile X-ray unit traveling control device is to adopt button or shift type control mostly; In the time of will realizing the change of speed or kinestate at every turn; Need to switch through pattern; And can not realize running turning, and increased the fussy degree of control, reduced work efficiency.
Summary of the invention
The goal of the invention of this utility model is: for overcoming the defective that above-mentioned traveling control device brings; Invent a kind of supply voltage of Position Control servomotor by the control linear potentiometer; Thereby realize the advancing of equipment, retreat, various kinestates such as turning; Medical mobile X-ray unit is moved flexibly, satisfy its use in the different location.
This utility model solves the technical scheme that its technical problem adopted: its structure is made up of upper rack, sectional wheel, rack bar, slide, roller shaft, connecting rod, driving shaft, potentiometer assembly, linear bearing, compression spring, thread bush, handle assembly; Its technical characterictic is: use the hand propelled handle assembly; This moment, driving shaft drivening rod and roller shaft slided in slide, and the little gear ring of sectional wheel and the engagement of fixed upper rack are because the slip of connecting rod; The bull gear of sectional wheel is stirred rack bar; It is slided in linear bearing, and realize the amplification of sliding distance promoting the potentiometer generation potential change in the potentiometer assembly according to the ratio of sectional wheel size gear ring; Thereby realize the startup of drive motors, equipment is advanced; Unclamp handle assembly, rack bar is homing under the combined effect of the back-moving spring of potentiometer and compression spring, and drive motors stops.And through regulating thread bush, the elastic force of spring is compressed in adjustment, thereby rack bar is accurately resetted.
The beneficial effect of this utility model is: simple in structure, easy for installation, cost is low, high efficiency, reset accurately, restoring force is adjustable, safe and reliable.
Description of drawings
Fig. 1, Fig. 2 are the example structure sketch maps of this utility model.
Among Fig. 1: 1, upper rack 2, sector 3, rack bar 4, slide 5, roller shaft 6, connecting rod
7, driving shaft 8, potentiometer assembly 9, linear bearing 10, compression spring 11, thread bush 12, handle assembly.
The specific embodiment
With reference to accompanying drawing, with hand propelled handle assembly (12), this moment, driving shaft (7) drivening rod (6) and roller shaft (5) slided in slide (4); The little gear ring of sectional wheel (2) and fixed upper rack (1) engagement; Because the slip of connecting rod (6), the bull gear of sectional wheel (2) is stirred rack bar (3), and it is slided in linear bearing (9); And realize the amplification of sliding distance according to the ratio of the big or small gear ring of sectional wheel (2); Potential change forward takes place in the potentiometer that promotes in the potentiometer assembly (8), thereby realizes the startup of drive motors, and equipment is advanced; Unclamp handle assembly (12), rack bar (3) is homing under the combined effect of the back-moving spring of potentiometer and compression spring (10), and drive motors stops; With pulling moving handle assembly (12), can make the potentiometer in the potentiometer assembly (8) that potential change backward takes place, thereby realize the reverse startup of drive motors, whole equipment is retreated; Unclamp handle assembly (12), rack bar (3) is homing under the combined effect of the back-moving spring of potentiometer and compression spring (10), and drive motors stops; Whole device can be through regulating thread bush (11), and the elastic force of spring (10) is compressed in adjustment, thereby rack bar (3) can accurately be resetted.Its advantage is: whole assembly forms a module, is convenient to dismounting and maintenance; The process that moves forward and backward can be set driving voltage according to the displacement of linear potentiometer, realizes the infinitely variable speeds campaign; When opposite power is given in the left and right sides, can realize the turning motion of equipment.
