The specific embodiment
This utility model hitching machinery part as shown in Figure 1 and Figure 2.Be provided with handrail 29 outside the casing 1, the lower end is provided with steamboat 22, is convenient to people and carries out.Casing 1 bottom is provided with balancing weight 21, with the balance of holding device.Casing 1 front is provided with door 2, can overhaul device.Casing 1 is provided with panel 30, and traction and physical therapy circuit board, touch-switch, display are all adorned thereon.On casing 1 inner bottom plating 24 motor 17, driving gear 18, idler gear 19, drive assembly 11, torsion seat 13, assembly supporting seat 10, leading screw 12, pulling force sensor 9, angle pulley 6, haulage cable 5 etc. are housed, wherein, drive assembly 11 is made up of travelling gear 28, bearing 25, shell 26, end cap 27 etc.
Be processed with the gear teeth on the cylindrical of travelling gear 28, interior round center has trapezoidal thread, and can produce two kinds of effects after leading screw 12 cooperates: the one, rotatablely moving of transmitting of motor changed over the rectilinear motion of leading screw; The 2nd, because the auto-lock function of trapezoidal thread can make motor 17 not resilience of pulling force when the operating position stops arbitrarily, thereby reach the adjustable purpose of pulling force continous-stable.Adopting the trapezoidal thread at circle center in motor 17 and the travelling gear 28 is key of the present utility model.
During this utility model work, the control wave rotation that motor 17 reception control circuits are issued, thus drive driving gear 18, idler gear 19, travelling gear 28 rotations, because the rotation of travelling gear 28, drive leading screw 12 moving linearlies, thereby produced pulling force.Torsion seat 13 is arranged on leading screw 12 lower ends, can prevent that leading screw 12 from rotating with travelling gear 28.The measurement of pulling force relies on pulling force sensor 9 to carry out.
Four angle pulleies 6 constitute assembly pulley, are loaded on the built-in beam 7, and can adjust its relevant position, thereby can adjust the angle of haulage cable 5 within the specific limits.Haulage cable 5 one ends connect with pulling force sensor 9, and the other end connects with haulage cable 3 with treatment through cable wire coupling 4.Base plate 24, built-in beam 7 are individually fixed on the column 23.
Traction apparatus control circuit such as Fig. 3, shown in Figure 5.Electric control system is by power circuit 48, pulling force sensor 9, A/D change-over circuit 32, central processing unit 34, display circuit 35, keyboard input circuit 33, output signal buffer circuit 36, stop electrical equipment 38, compositions such as executive circuit 37, motor 17.Control circuit is to adopt conventional to come the control circuit of control step motor 17 runnings by central processing unit 34 according to the size of pulling force sensor 9 transmitted numbers, just the control sequence difference of establishment.
A/D change-over circuit 32 is made up of the ADC0809 chip.Pulling force sensor 9 analogue signal of sending converts digital signal to through this chip, offers central processing unit 34 through data/address bus again and understands.
Stepping motor control circuit (executive circuit 37) is the finished parts of together supplying with motor 17, the adaptive biphase and four phase composite stepper motors of this control circuit, adopt bipolar driving, the control of PWM constant current chopper, input signal adopt light every, support synchronizing, 2,4,8 segmentations (the motor step angle is respectively 1.8 °, 0.9 °, 0.45 °, 0.225 °).Can make the stepper angle fraction of motor just because of this circuit, just improve the precision that pulling force is set.
This device is provided with the stroke protection, and its range is 55 millimeters.Holding circuit is finished by stop circuit 38.Stop circuit 38 is included in to be equipped with on the pulling force sensor 9 with it together does straight-line clip 8 and dark slide 14; when the driven by motor guide screw movement arrives limit inferior point (or limit superior point); dark slide 14 also moves to when being loaded on following (or on) photoswitch 16 places on the power panel 15 and covering light emitting diode institute isolychn; photoswitch 16 output electronegative potentials; make P13 (or P14) the pin current potential step-down of central processing unit 34; program uses inquiry mode to check P13 (or P14) pin current potential; after program inquiring arrives the variation of P13 (or P14) pin current potential; to start corresponding program and handle just (or anti-) commentaries on classics of motor 17, thereby reach the purpose of protection traction apparatus range.
The technical specification of traction element is: rated voltage is 220V ± 5%, and pulling force is that 0~20KG is adjustable continuously, and the pulling force precision is ± 0.1KG (reality can reach 0.001KG) that stroke is 55 millimeters.
The using method of traction element is as follows:
(1), will treat haulage cable 3 earlier connects with haulage cable 5 usefulness cable wire couplings 4;
(2), after the energising, be provided with by button and allow the maximum pull value; When device detected actual pulling force above this maximum pull value, device was with autostop and send sound and light alarm;
(3), by push " advancing continuously ", " moving back continuously ", " stepping ", " step moves back " four buttons can be controlled motor movement respectively and reach: increase continuously pulling force; Reduce pulling force continuously; Crawl increases pulling force (every crawl once approximately increases the value of thrust of 0.1KG); Crawl reduces pulling force (every crawl once approximately reduces the value of thrust of 0.1KG);
(4), by after manually adjusting value of thrust, can push " dangling " button, the setting of " dangling " button will be simulated the state of weighing exactly fully, because the variation of patient's position in distraction procedure, value of thrust is changed, and for guaranteeing curative effect, this variation is unallowed; For this this device has designed " dangling " state, under this state, device compares by continuous detection value of thrust and the value of thrust of adjusting, and when finding that value of thrust is excessive, 17 counter-rotatings of control motor reduce pulling force; When finding that value of thrust is too small, control motor 17 is just changeing, and increases pulling force; Guarantee the constant purpose of value of thrust thereby reach.
(5), the traction finish, pressing keys is backed to square one motor, unclamps cable wire coupling 4, cuts off the electricity supply.
