inclined-plane to contacting, and with the second driving sliding block Gradually stretch out the second guide cylinder, the second active drive inclined-plane of the second driving sliding block gradually drives the second the second quilt for being struck block Dynamic driving inclined-plane drives the second sliding sleeve to be slided towards the 4th far from extreme direction by the 4th by proximal direction, and the second sliding sleeve passes through third pressure Spring drives the second driven pulley in the same direction, the second driven pulley gradually reduce four pressure springs while, second is passive Second passive tilt circumferential surface of friction pulley gradually with the second active friction wheel second active tilt week face contact.As clump weight master Body and counterweight adjust part and are intended to slide along the first guide rail and the second guide rail by the pulling force of gravity or drag rope When, the first vertical rack driving the first driving gear band moves the rotation of the first active rotating shaft, and the first active rotating shaft drive first is actively Friction pulley and the rotation of the first driving gear, the first driving gear drive the first driven gear to drive the rotation of the first passive rotating shaft, the One passive rotating shaft drives the rotation of the first driven pulley, since the diameter ratio a of the first driving gear and the first driven gear is less than The diameter of first active friction wheel and the first driven pulley ratio b, although the first driven pulley is along the first active friction wheel Rotation direction rotation, 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 generates friction inhibition to the first active friction wheel to generate the first reaction resistance always；Second Vertical rack driving second driving gear band move the second active rotating shaft rotation, the second active rotating shaft drive the second active friction wheel and The rotation of second driving gear, the second driving gear drive the second driven gear to drive the rotation of the second passive rotating shaft, and second by turn Axis drives the rotation of the second driven pulley, actively less than second due to the diameter of the second driving gear and the second driven gear ratio c The diameter of friction pulley and the second driven pulley ratio 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 generates friction inhibition to the second active friction wheel always and generates the second reaction resistance, this second reaction Resistance matches the carrier weight in common equilibrium carriage and carriage with the first reaction resistance and counterweight block main body.Wherein, First pressure spring can keep the first sliding driving part to the driving force of the first driven pulley, and then keep the first driven pulley Position in the first passive rotating shaft；Third pressure spring can keep driving of the second sliding driving part to the second driven pulley Power, and then keep position of second driven pulley in the second passive rotating shaft；5th pressure spring can keep the first power sliding block pair The driving force of first driving sliding block, and then the first active drive inclined-plane of the first driving sliding block and first is kept to be struck the of block The contact force on one passive matrix inclined-plane；6th pressure spring can keep the second power sliding block to the driving force of the second driving sliding block, in turn 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 pressure spring and the 5th pressure spring match the first passive tilt circumferential surface and the first active friction for keeping the first driven pulley The contact force and frictional force of first active tilt circumferential surface of wheel are stablized, will not be by too big shadow in the environment in vibration It rings, 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； Third pressure spring and the 6th pressure spring match the second passive tilt circumferential surface and the second active friction wheel for keeping the second driven pulley The second active tilt circumferential surface contact force and frictional force stablize, in the environment in vibration will not by too big influence, The driving force that the second power sliding block can also be buffered avoids the power of the second power sliding block excessively stiff and damages associated mechanisms.Respectively Movement is mechanization, was not necessarily to multiple-energy-source as power, and was low power consuming product.Compared with prior art, of the invention efficient Low consumption fall arrest vertical lift, can be balanced at any time counterweight to carriage on the basis of energy-efficient, and low energy consumption, and drag rope is not Easy fracture, mechanism operation lasting stability is reliable, effectively avoids carriage from falling and causes human casualty accident, practical.
