Abstract
A detachable self-balancing stretcher comprises a main stretcher, an inner side adjustable stretcher and an outer side fixed support stretcher, wherein the main stretcher is assembled on a stretcher support of the inner side adjustable stretcher, and a bearing is installed between the inner side adjustable stretcher and the outer side fixed support stretcher. One end of an electric drive pusher is fixed on an inner side reinforcing member of the inner side adjustable stretcher, the other end of the electric drive pusher is fixed on an outer side reinforcing member of the outer side fixed support stretcher, an obliquity sensor is installed below a main shaft, real-timely detects the inclination angle of the stretcher, and sends the angel data to a controller, the electric drive pusher can be controlled by the controller to drive the inner side adjustable stretcher to rotate around the main shaft under slight bearing resistance, so a function of automatically adjusting the stretcher to keep horizontal is realized.
Description
Technical field
The present invention is detachable self-balancing stretcher, belongs to a kind of self-balancing stretcher that can both safe and stable operation on the road surface of level land, stair and relief.
Background technology
Stretcher is the rescue tool that a kind of patient of transporting, the wounded use always.In various disasters and disaster scene, road is rugged and rough on the one hand, relief, and slope change is big; In the transport disease man-hour through the stair road, the stair activity gradient is bigger on the other hand, and this all causes the inclination of stretcher easily.Over-tilting in the handling process tends to increase the weight of patient's misery, and patient's the state of an illness is increased the weight of, and especially for patients such as hemorrhage, fracture, internal injuries, even can influence its life security.Therefore in transportation, the stationarity of stretcher has been proposed very high requirement, how to take effective method to avoid having become a great problem of rescue work to reduce the secondary injury.
Up to the present; Domestic research to the self-balancing stretcher is also less, the stretcher structure of adjustment is automatically also arranged in the prior art, but exist some shortcomings; Like the patent No. is the Chinese utility model patent " a kind of simple and easy balance stretcher " (notification number is CN202027814U) of ZL201120046584.8; The angle that when the upward slope descending, needs the manual operation handle to regulate stretcher, the accuracy of adjusting and the stable skilled usage degree that depends on the rescue personnel fully are difficult to guarantee.Self-balancing stretcher device in other researchs or because of design defect can not prevent to topple well, security and stability is poor, or because of complex structure, involves great expense, specific condition are down and impracticable.
Summary of the invention
Technical problem to be solved by this invention is the present situation to prior art, provides that a kind of cost is low, volume is little, detachable, the self-balancing stretcher that is convenient for carrying.
The technical scheme that this patent technical solution problem is adopted is: detachable self-balancing stretcher comprises main stretcher, inboard scalable stretcher, outside fixed support stretcher and stretcher balanced component; Wherein the stretcher balanced component comprises electric pushrod, angular transducer and control chamber; Be electrically connected between electric pushrod, angular transducer and the control chamber; The ARM panel is equipped with in control chamber inside, and the ARM panel is controlled electric pushrod elongation or amount of contraction through the angle of inclination of the stretcher that angular transducer records; Main stretcher is contained on the inboard scalable stretcher; Connect through bearing between inboard scalable stretcher and the outside fixed support stretcher; Electric pushrod one end is fixed on the inboard scalable stretcher; The other end is fixed on fixed support stretcher bottom, the outside, and obliquity sensor is installed in inboard scalable stretcher below, and control chamber is installed in fixed support stretcher bottom, the outside.
Main stretcher comprises main stretcher rod and canvas, and canvas is fixed between the main stretcher rod; Inboard scalable stretcher comprises inboard stretcher rod, inboard connector, inboard girth member, stretcher holder, main shaft; Inboard stretcher rod is fixedly connected with inboard connector; Be fixedly connected between inboard girth member and the stretcher holder; Be fixedly connected between main shaft and the inboard connector; Outside fixed support stretcher comprises outside stretcher rod, outside connector, outside girth member, footpost; Be fixedly connected between the outside stretcher rod and the outside connector; Be fixedly connected between the outside girth member and the outside connector; Main stretcher is installed in the stretcher holder of inboard scalable stretcher; Between inboard scalable stretcher and the outside fixed support stretcher bearing is installed; Bearing outer ring is installed in the dead eye of outside connector of outside fixed support stretcher; Inner ring is installed on the little load-bearing axle and links together the dead in line at main shaft and two bearings place through the inboard connector of little load-bearing axle and inboard scalable stretcher.
Electric pushrod one end is fixed on the inboard girth member of inboard scalable stretcher, the other end be fixed on fixed support stretcher bottom, the outside outside girth member on,
Obliquity sensor is installed in the main shaft below; Detect the stretcher angle of inclination in real time and send angle-data to controller; Electric pushrod can rotate around main shaft under very little bearing resistance at the inboard scalable stretcher of drive under the control of controller, realizes regulating automatically the function of stretcher maintenance level.
Electric pushrod is selected the 24V direct current drive push rod of thrust 1000N, stroke 200mm for use; The base part of electric pushrod be installed in fixed support stretcher bottom, the outside outside girth member on; The pusher section of electric pushrod is installed on the inboard girth member of inboard scalable stretcher and is positioned at upper half of human body one side; After installing, electric pushrod is positioned at the horizontal centre of stretcher, vertically near upper half of human body one side.Can guarantee the horizontal left-right symmetric of stretcher like this, stressed even, vertically be partial to the heavier side of grantee's body weight, the safety that can improve stretcher.
After the ARM panel powers on; Obliquity sensor is measured the stretcher angle of inclination, and dateout adopts half-duplex operation mode TTL serial ports, and it directly is sent to the ARM panel; The ARM panel is handled the real-time inclination angle value receive and is compared with the preset level angle; The elongation and the contraction of control electric pushrod after the comparing data, making stretcher is that rotating shaft is rotated with the main shaft, drives stretcher with electric pushrod and compensates because the angle that extraneous relief variation causes tilts around the rotation of main shaft; Thereby realize real-time adjustment to the stretcher angle of inclination; The ARM panel constantly receives the angle value from obliquity sensor, and constantly adjusts the elongation of electric pushrod, lets the self balancing purpose of stretcher thereby reach.
Beneficial effect:
1. electric pushrod of the present invention can rotate around main shaft under very little bearing resistance driving inboard scalable stretcher under the control of controller, realizes regulating automatically the function that stretcher keeps level, lets the self balancing purpose of stretcher thereby reach; Therefore can prevent well that stretcher from toppling, safety and stability is good;
2. overall structure of the present invention is simple and be easy to control, so manufacturing cost is comparatively cheap, and footpost and stretcher are connected on the stretcher rod of the outside and by the bakelite screw through the footpost jacket casing on the footpost and fix, and have installation and removal characteristics easily;
3. in the footpost outer tube damping spring is housed, makes stretcher have good damping effect in the course of the work.
