Degree and move distance.
Steel wire rope train constituent relation is as follows: the two ends of flexible wire ropes (8) are provided with link (2), the middle part of steel wire rope
Being fixed on driving wheel (6), driving wheel (6) is arranged in Steel rope drive mechanism, and steel wire rope utilizes front-wheel (22), breast wheel
(19), the support of supporting roller (3), with driving wheel (6) constitute moving loop, supporting roller (3) can rotate in the horizontal direction, institute
Wire rope pulley is had to be respectively provided with groove separation preventing device.
Screw (13) in Steel rope drive mechanism and the peace by driving wheel (6) of the driving wheel (6) in steel wire rope train
Dress seat is fixing to be connected, and screw (13) drives together with guide rail slide block (14) and supports driving wheel (6) and moves along a straight line.
The linear motion of driving wheel (6), is driven steel wire rope (8), is respectively taken turns by other in steel wire rope train, folding and unfolding steel wire
Rope (8), it is achieved the barbell on link (2), moves up and down under the front boom of frame (1).
Link (2) is that a rare earth material Nd-Fe-B permanent magnetic inhales ring, is rotated by handle, thus changes the internal neodymium ferrum of suction ring
The magnetic force systems of boron, reaches the function of the sticking by bar or release, and handle has the work of mechanical interlocking barbell (1) bar concurrently simultaneously
With, the two acts on simultaneously and prevents barbell from slipping.
Fix the counterweight (5) being connected with driving wheel (6) mounting seat, effect is the weight of balance rope drive mechanism parts
And the impact that frictional force is on barbell exercise.
It is arranged on the baffle plate (20) in frame, before plant equipment, plays isolation plant equipment and athletic effect, its
On operation, display, message plate (10) device are installed, function is: operation the machine, set weight lifting action, set weight lifting weight, set
Determine athlete's height etc.；Show such as: timing, weight lifting weight and the information such as accumulating weight, exercise number of times；Voice message etc..
Front roller box (21) is arranged on the front end of frame cantilever, and the support shaft of front-wheel (22) is arranged on the inspection in front roller box (21)
Survey on device, be provided with detection sensor, in order to detect barbell by steel wire rope be transmitted to the gravity on front-wheel (22) and
Steel wire rope (8) is applied to the change of barbell pulling force, and local controller, according to the parameter of sensor acquisition, controls Steel rope drive mechanism
Do corresponding action.
One precompressed mechanism is set in front roller box (21), coordinates with front-wheel (22), in case steel wire rope (8) answers masterpiece at self
With lower disengaging setting position, the steel wire rope (8) being stretched in steel wire rope train.
Wire rope standard case (23) is arranged on the lower section of front roller box (21), swing detection arm (24) thereon and sleeve pipe (25)

From the angle of vertical direction, local controller, according to the parameter of sensor acquisition, controls Steel rope drive mechanism and does corresponding action.
During training, after the barbell being in calibration position is hung in link (2) by athlete, lock bar, then
Above set relevant parameter at operation, display, message plate (10) and press initiating key, Steel rope drive mechanism action, drive steel wire
Rope (8) is tensioning steel wire rope (8) under steel wire rope train guides, and is applied to barbell (1) pulling force F upwards.
Sensor in front roller box (21) passes through front-wheel (22), the gravity of the barbell (1) suffered by detection steel wire rope (8), basis
Machine controller controls the action of Steel rope drive mechanism, makes steel wire rope (8) be applied to the upwards pulling force F0 of barbell (1), relative to
The weight of barbell, this power is negligible.
Athlete upwards picks up the initial actuating of barbell (1) so that pulling force F is zero, and local controller is according to the inspection of sensor
Survey parameter, control the action of Steel rope drive mechanism, keep the steel wire rope (8) the upwards pulling force F0 to barbell (1).
Athlete upwards pick up barbell (1), execution midway pause action, the stress of caused front-wheel (22)
Running parameter, is detected and sends to local controller by sensor, controls the action of Steel rope drive mechanism, keeps steel wire rope
(8) the upwards pulling force F0 of barbell (1) it is applied to, and self-locking at any time Steel rope drive mechanism, to prevent barbell (1) midway from falling.
Athlete is successfully completed weight lifting action, and barbell (1) reaches summit associated in setup parameter and weight lifting rule limit
After the fixed retention time, by technical regulation, athlete prepares to throw forward the barbell in selling (1), and now, controller controls braking
The braking to Steel rope drive mechanism freed by device, throwing forward the barbell exercise in selling in order to avoid affecting athlete, keeping steel simultaneously
Cord is applied to the upwards pulling force F0 of barbell.
The tenesmus track of the barbell (1) that passive movement person dishes out, during being included in weight lifting, the barbell that baulk causes
(1) tenesmus track, string the sleeve pipe (25) being enclosed within steel wire rope (8) is converted into deflection angle and the beat speed of detection arm (24)
Degree, the sensor on wire rope standard case (23) detects the parameter obtained, and the sensor in roller box (21) before coordinating, by front
The detection parameter of the gravity of the barbell (1) suffered by wheel (22) detection steel wire rope (8), controls Steel rope drive as local controller
Mechanism, takes the foundation of protection action.
Athlete's front throwing normally is made, and the deflection angle that wire rope standard case (23) detects is the most initial angle
Degree, and the paired sensor institute testing result of frame two ends cantilever is close.
If the deflection angle that wire rope standard case (23) inner sensor detects is the most initial angle；Or detection
The deflection angle gone out is the deflection angle on barbell (1) axis direction；Or the result of the pair of sensors detection of identical function has
Bigger difference, illustrates that athlete creates error, after the action of current kinetic person is probably due to tired or technical reason
Fall, skew or barbell out of control, local controller according to the parameter of sensor acquisition, controls Steel rope drive mechanism and takes protection dynamic
Brake or promote barbell (1), and send warning message.
Local controller is prior art products.
Present invention employs above-mentioned structure and working method, it is possible to reach moving by weight lifting technical key point routing motion person
Make, auxiliary couch and other staff, the purpose of total process protective athlete safety.
