Abstract
The invention relates to a lifting-controllable protector. The protector comprises a fixing plate, a movable side plate located through a first hinge pin, a rope winding base arranged between the fixing plate and the movable side plate, and a rope wheel. The rope wheel is located on the fixing plate through a second hinge pin. The protector is characterized in that the rope winding base encloses the first hinge pin and is provided with a braking face and an arc face for rope winding. The braking face faces one side of the rope wheel. The section of the rope wheel is an asymmetric polygon, and is a wheel face with more than three round edges, and the wheel face is provided with a rope groove; at the beginning of stressing the rope wound around the rope wheel, the rope wheel is driven to rotate by a small angle, and one round edge enables the rope to abut against the braking face of the rope winding base for brake stopping; an angle is formed between a control arm in linkage with the rope wheel and the fixing plate, and the control arm can be controlled manually. With the help of matching of the polygonal rope wheel and the rope winding base, safety protection of automatic braking stopping can be achieved, the protector can be manually controlled to descend, and the polygon rope wheel has the characteristic of slow descending.

Detailed description of the invention:
Embodiment one:
Referring to figs. 1 through Fig. 4, this example is the controllable lift protector of single rope, comprises fixed head 1, mobile side board 2, is located at rope sheave 3 between fixed head 1 and mobile side board 2 and wiring seat 4; Mobile side board 2 and fixed head 1 upper end are positioned together by the first bearing pin 5, and rope sheave 3 is positioned on fixed head 1 by the second bearing pin 51; Wiring seat 4 is enclosed in outside the first bearing pin 5, has the arc surface 42 of a braking surface 41 and wiring, and braking surface 41, towards rope sheave 3 side, coordinates with rope sheave 3 and realizes braking; More particularly, the arc surface 42 of wiring seat 4 by fixed head 1 directly bending and molding, good integrity and have good rigid relation; Braking surface 41, by a steel plate forming, has braking surface 41 and the wiring arc chord angle 411 of disjunctor and the two fixed shaft hole faces 412 in vertical braking face with it, is fixed on the first bearing pin 5 by two fixed shaft hole faces 412.
Described rope sheave 3 cross section is asymmetric polygon, and this example is quadrangle, the grooving 32 wheel face having four round ribs 31 and provide rope 7 to walk around; Circle rib 31 can play slow effect of falling, again not easily scratch rope; Rope sheave 3 and control arm 6 link, and specifically control arm 6 is directly shaping together with rope sheave 3, ensures its rigid, manipulates more reliable.Second bearing pin 51 is arranged with a torsion spring 52, and conflicting respectively on fixed head 1 and rope sheave 3 in these torsion spring 52 two ends, remains that control arm 6 is flapped toward the trend of fixed head 1.In fact form scissors between control arm 6 and fixed head 1 and pitch structure, it is minimum that torsion spring 52 effect is the angle that control arm 6 and fixed head 1 scissors are pitched, control arm 6 leans against on fixed head 1 side in other words, also be that rope sheave 3 is resetted, get back to design attitude, now rope sheave 3 is maximum with braking surface 41 spacing of wiring seat, so that around the operation of upper rope 7; Moreover rope 7, when doing enhancing action, allows rope 7 easily to pass through.Control arm 6 end is positioned with one handle 61 by hinge 53, and on hinge 53, be arranged with a little torsion spring 54, this little torsion spring 54 remains that handle 61 is close to the trend of control arm 6, only whenever necessary, hand is for open handle 61, to increase the arm of force, can comparatively light rope sheave 3 be resetted, to control to decline; Further, control arm 6 is convexly equipped with protruding pin 62 towards handle 61 side, handle 61 offers an arc groove 610 towards control arm side, the central angle of this arc groove 610 is not more than 180 degree, protruding pin 62 inserts in this arc groove 610, also namely handle 61 is after hinge swings a design angle, and the adjutage that namely can be used as control arm 6 uses.
Corresponding second bearing pin 51 position of mobile side board 2 is provided with locating hole 21, and after this locating hole 21 overlaps with the second bearing pin 51 end, mobile side board 2 aligns with the connecting hole 22 of fixed head 1 lower end, provides the fixing of rope or fastener; In this legend, locating hole 21 is lipostomous; Second bearing pin 51 end has a cylinder chamber 511, is provided with spring 512 and a button 513 in this cylinder chamber 511, and this button 513 is slided by a horizontal bolt 514 and is positioned in cylinder chamber 511, and this spring 512 remains button 513 protruding state; Corresponding mobile side board 2 side is provided with oblique protuberance 23, and this oblique protuberance 23 inner surface points to locating hole 21; Mobile side board 2 rotary course, this oblique protuberance 23 inner surface energy compression button 513, until when the second bearing pin 51 overlaps with locating hole 21, this button 513 ejects under the action of the spring again, inserts the location structure that locating hole 21 forms mobile side board 2; Reverse operating, namely needs artificially pressed down by button 513 and promote mobile side board 2.In this structure, the location of mobile side board 2 is relatively reliable, can not misplace separately.
As Fig. 3 and Fig. 4, remove the schematic diagram after mobile side board 2, operation is initial, because rope sheave 3 is under torsion spring 52 acts on, get back to design attitude, now rope sheave 3 and wiring seat 4 form rope channels open, only need S shape be become to wind rope 7 direction on request, mobile side board is closed in pass, buckles fastener etc. and namely completes the preparation that declines; During decline operation, the rope 7 walking around this rope sheave is initially stressed, and rope sheave 3 is driven to rotate a low-angle, wherein round rib 31 rope 7 can be pressed on wiring seat braking surface 41 on braking; Now, and between the control arm 6 that links of rope sheave and fixed head 1 angle is opened, for handle 61 provides an exercisable angle; As Fig. 4, open handle 61, and firmly toward fixed head 1 one side oscillation, can remove the extruding force to rope 7, rope 7, under gravity traction, realizes sliding around rope sheave 3 and wiring seat 4; Decline process, operator also needs another hand to be pressed on wiring seat 4 downwards by rope 7 movable end, both can slow down decrease speed, and also can realize stop if desired.
Embodiment two:
With reference to Fig. 5, Fig. 6 and Fig. 7, for the example of duplex type decline protector, its basic structure and upper example together, are just provided with two rope sheaves 3 between fixed head 1 and mobile side board 2, two rope sheaves 3 interfix and are positioned on fixed head 1 by the second bearing pin 51, and also namely two rope sheaves 3 are synchronization structure; Corresponding two rope sheaves of arc surface 42 of wiring seat 4 are provided with twice grooving 32, avoid two ropes 7 mutually intersect and press from both sides dead; Wiring seat 4 is fixed on fixed head 1 side by the first bearing pin 5 and a short pin 55, avoids wiring seat 4 to rotate.
In this structure, the locating hole 21 on mobile side board 2 is opening port, can be clipped in the end of the second bearing pin 51 after swing, forms positioning relation.Moreover be processed with an arc groove at wiring seat 4 towards mobile side board 2 end face, mobile side board 2 is towards the spacing salient point 24 of wiring seat 4 side projection, and this spacing salient point 24 inserts in arc groove, form the constraint of mobile side board 2 pendulum angle.
Controllable lift protector is mainly used to the automatic protection of fall arrest, and the object of controlled and slow decline, and this equipment does not hinder the operation of rising yet; During rising, the movable end of rescuer on the other hand firmly downwards-pulling rope 7, another have gentle hands tow 7 makes rope in order, can drive rope sheave 3 stop again in time when interval is stressed; When exerting oneself downwards-pulling rope, rope sheave loses external force, and it resets under torsion spring 52 acts on, and made rope channels open, another hand easily can make safety operation in order.
