is driven, and the first adjusting is driven monomer and second Adjust driving monomer drives the first balance adjustment execution monomer and the second balance adjustment to perform monomer and be balanced adjusting respectively, makes Balance weight device reaches balance with carriage, and the tractive force that carriage lifting driving motor need to only provide very little can carry out carriage Lifting, carriage lifting driving motor can also be mitigated significantly to traction rope by reducing while carriage lifting drives the energy loss of motor The strand power of rope winding, drag rope will not be stressed concentration and be not likely to produce the damage such as fracture, and drag rope service life is big Big to extend, carriage is not likely to produce situations such as falling.In actual use, under the control of the controller, sliding power device Worm screw component to turbine part carry out it is a certain it is conterclockwise rotate drive, turbine part at the same time drive the first screw rod and second Screw rod rotates the corresponding number of turns, and first the first power sliding block of screw drive is along the first guide cylinder by the first power input port direction towards the One power output mouth direction is slided, and the first power sliding block drives the first driving sliding block by the 5th compression spring in the same direction, and first Driving sliding block by the first prominent active drive inclined-plane with first be struck block the first passive matrix inclined-plane to contacting, and with The first driving sliding block and gradually stretch out the first guide cylinder, the first quilt of the gradual driving in the first active drive inclined-plane of the first driving sliding block First passive matrix inclined-plane of slide block drives the first sliding sleeve to be slided by second by proximal direction towards second away from extreme direction, and first Sliding sleeve drives the first driven pulley by the first compression spring in the same direction, and the first driven pulley gradually reduces the second compression spring Meanwhile first first active tilt side face of the first passive tilt side face gradually with the first active friction wheel of driven pulley connect Touch；Second the second power sliding block of screw drive is along the second guide cylinder by the second power input port direction towards the second power output mouth side To slip, the second power sliding block drives the second driving sliding block by the 6th

passive matrix inclined-plane to contacting, and with the second driving sliding block Gradually stretch out the second guide cylinder, the second active drive inclined-plane the second quilt that gradually driving second is struck block of the second driving sliding block Dynamic driving inclined-plane drives the second sliding sleeve to be slided by the 4th by proximal direction towards the 4th away from extreme direction, and the second sliding sleeve passes through the 3rd pressure Spring drives the second driven pulley in the same direction, the second driven pulley gradually reduce four compression springs while, second is passive Gradual the second active tilt circumferential contact with the second active friction wheel of second passive tilt side face of friction pulley.As clump weight master Body and counterweight adjust part and are subject to the pulling force of gravity or drag rope to be intended to along the first guide rail and the slip of the second guide rail When, the first vertical rack drives the first drive gear to drive the first active rotating shaft to rotate, and the first active rotating shaft drives first actively Friction pulley and the first driving gear rotate, and the first driving gear drives the first driven gear to drive the first passive rotating shaft to rotate, the One passive rotating shaft drives the first driven pulley to rotate, since the diameter of the first driving gear and the first driven gear is less than than a The diameter of first active friction wheel and the first driven pulley is than b, although the first driven pulley is along the first active friction wheel Rotation direction rotate, but the velocity of rotation of the first driven pulley is consistently less than the velocity of rotation of the first active friction wheel, That is the first driven pulley produces friction inhibition to produce the first reaction resistance to the first active friction wheel all the time；Second Vertical rack drive the second drive gear drive the second active rotating shaft rotate, the second active rotating shaft drive the second active friction wheel and Second driving gear rotates, and the second driving gear drives the second driven gear to drive the second passive rotating shaft to rotate, and second by turn Axis drives the second driven pulley to rotate, due to the diameter of the second driving gear and the second driven gear than c less than second actively The diameter of friction pulley and the second driven pulley is than d, although the second driven pulley is along the rotation side of the second active friction wheel The velocity of rotation of the second active friction wheel, i.e. the second quilt are consistently less than to the velocity of rotation of rotation, but the second driven pulley Dynamic friction wheel produces friction inhibition to produce the second reaction resistance to the second active friction wheel all the time, this second reaction Resistance is engaged the carrier weight in common equilibrium carriage and carriage with the first reaction resistance and counterweight block main body.Wherein, First compression spring can keep driving force of the first slip driving part to the first driven pulley, and then keep the first driven pulley Position in the first passive rotating shaft；3rd compression spring can keep driving of the second slip driving part to the second driven pulley Power, and then keep position of second driven pulley in the second passive rotating shaft；5th compression spring can keep the first power sliding block pair The driving force of first driving sliding block, and then keep the first active drive inclined-plane of the first driving sliding block and first to be struck the of block The contact force on one passive matrix inclined-plane；6th compression spring can keep driving force of second power sliding block to the second driving sliding block, and then Keep second driving sliding block the second active drive inclined-plane and second be struck block the second passive matrix inclined-plane contact force；From And the first compression spring and the 5th compression spring are engaged the first passive tilt side face and the first active friction for keeping the first driven pulley The contact force and frictional force of first active tilt side face of wheel are stablized, and too big shadow will not be subject in the environment of vibration Ring, can also buffer the driving force of the first power sliding block, avoid the power of the first power sliding block excessively stiff and damage associated mechanisms； 3rd compression spring and the 6th compression spring are engaged the second passive tilt side face and the second active friction wheel for keeping the second driven pulley The second active tilt side face contact force and frictional force stablize, too big influence will not be subject in the environment of vibration, The driving force of the second power sliding block can be also buffered, avoids the power of the second power sliding block excessively stiff and damages associated mechanisms.Respectively Action is mechanization, is low power consuming product without crossing multiple-energy-source as power.Compared with prior art, it is of the invention efficient Low consumption fall arrest vertical lift, it can be balanced counterweight at any time on the basis of energy saving to carriage, and energy consumption is low, and drag rope is not Easy fracture, mechanism operation lasting stability is reliable, effectively avoids carriage from falling and causes human casualty accident, highly practical.
