The utility model discloses a flexible rope body, including the flexible rope body lower extreme fixedly connected with hang, hang including rings 216, flexible rope body lower extreme fixed connection is in rings upper end, under bearing shaft 40 fixed connection rings, sling frame 217 middle part rotates to be connected on the bearing shaft, connects the suspender on the sling frame and is used for the constraint patient, the suspender subtracts heavy trainer commonly used at present, no longer shows in the picture, the flexible rope body of rings upper end on wear to be equipped with nylon cover 218, fixedly connected with fine motion limit switch 221 under subtracting heavy platform or skew detection sensor, the fine motion limit switch is touched when the nylon cover rises to the settlement height, fine motion limit switch is connected to the controller.
The working process of the dynamic weight reducing device is as follows: after a patient is bound by the sling, a weight reduction value (the static balancing instrument is a mature product at present and has the function) trained by the patient is obtained on the static balancing instrument under the state that the sling is loosened, the sling is driven to rise by a back weight reduction motor, the weight reduction force can be converted according to a signal of a tension sensor, the weight reduction force is equal to the weight reduction value, under a weight reduction training mode, a flexible rope body is in a tensioning state, when the patient moves back and forth, the flexible rope body can press the end part of a nylon sliding block on a corresponding deviation detection sensor, the nylon sliding block moves towards the direction far away from the rope body, two laser correlation switches correspond to a through hole after the nylon sliding block moves to a certain displacement, at the moment, a controller can obtain a signal for sending back and forth displacement, the weight reduction table moves according to the moving direction of the patient, when the flexible rope body leaves the end part of the nylon sliding block, the nylon sliding block automatically, if the tightness of the rope body is changed due to height change in the moving process, the controller timely adjusts the size of the weight reducing force according to signals of the tension sensor, after the weight reducing table triggers the limit switch, the moving driving motor is locked, even if the light correlation switch is correspondingly conducted with the position of the through hole, the moving driving motor does not act, the weight reducing platform moves forward, a patient can carry out weight reducing training, when the training is finished and the moving driving motor needs to work, a manual button on the controller drives the moving driving motor to work, the weight reducing table can leave the limit switch, and at the moment, the flexible rope body triggers the patient to move the sensor and then the moving driving motor starts to act.
This dynamic weight reduction active and passive balance training system, before the patient trains, stand earlier and dress under doctor's help on static balancing appearance and subtract heavy constraint area and protection waist, flexible rope body is in the lax state of certain degree this moment. Then the patient carries out the displacement of the body gravity center of the static balance test in all directions and records the test result, and simultaneously the weight information of the patient is also detected and uploaded to the control system, and the weight reduction value required to be given to the patient is obtained according to the detected weight of the patient (the weight reduction value obtained by the static balance instrument is the mature technology currently used). The middle box body sends a control command to drive the weight reduction motor to act, and a force value is detected by the tension sensor and fed back to the control system, so that the tension of the rope is always the same as the weight reduction value. When a patient moves forwards along a slope or goes upstairs, the gravity center of the body of the patient moves forwards, the flexible rope body rope swings forwards and has a small-range inclination angle with the gravity of the patient, when the compression nylon sliding block slides to a certain position in the sliding rail, visible laser of the correlation laser switch penetrates through a through hole in the nylon sliding block and is connected with a signal, the signal is fed back to the controller, the controller drives the movable driving motor to rotate, the weight reducing table is driven to move forwards through two synchronous belt transmissions, the limiting switch is touched on the weight reducing platform after the patient goes up the platform, the movable driving motor is powered off and stops working, the movable driving motor is in a reverse self-locking state, at the moment, whether the correlation laser switch is switched on or the flexible rope body swings around or left and right of the patient is judged. A patient stands on a training platform, and the platform is in a horizontal state under the action of 2 vertically arranged electric cylinders; when a patient stands stably on the movable platform, the system is driven by the weight reduction motor to hang and descend for a certain distance, so that the flexible rope belt is in a loose state to a certain degree, and the rehabilitation training of the patient is facilitated. At the moment, the flexible rope body and the ground tend to be in a vertical state, the opposite laser switch is blocked by the nylon block to be incapable of conducting, the mobile driving motor is powered off and does not work, and the weight reduction platform stops advancing at the moment. The patient walks under the independent consciousness of the patient from the static balancing instrument to the training platform, the burden of a doctor is relieved, and the purpose of assisting walking training can be achieved. The patient firstly carries out dynamic detection in a certain resistance active training mode on a training platform (at the moment, the electric cylinder is in a power-off state); after the dynamic detection is finished, the 2 electric cylinders simultaneously act and are kept electrified according to the feedback data of the tension pressure sensor, so that the movable platform is kept at a certain angle (such as 7 degrees) to carry out the stability limit test of the patient. Passive training may also be performed. After the training is finished, the patient turns around and puts down the training platform to the ground, at this moment, the movable driving motor is controlled through the manual button to rotate so that the weight reduction platform leaves the limit switch, the locking state of the movable driving motor is removed, and the patient moves independently again. The method is the same as the process control method of the upper training platform, after the treatment of a patient is finished, a doctor controls the weight reduction motor to rotate through the button to contract the flexible rope body, and the hanging moves upwards until the nylon sleeve touches the top micro limit switch and then the weight reduction motor stops.
