When work high above the ground personnel are landed, rope sheave fast downlink on rope is driven by human body, correspondingly, rapid drive Large Gear Shaft, pinion shaft quick rotation, final drive centrifugal brake component operation, thus by staff's decrease speed within very short time (e.g., about 0.2 second) control in the safe range of 0.5-2m/s, until security platform, reach object that is quick, safe falling.
For reasonably increasing the contact area between rope and rope sheave as far as possible, increase frictional force therebetween, avoid the relative motion between rope and rope sheave further, ensure that the potential energy of human body decline almost all can be converted into the kinetic energy of gear, thus fast starting centrifugal brake assembly, stablize decrease speed, inventor devises following structure especially: the grooving both sides of inside, described large storehouse are provided with grooving projection, rope can press to inside rope sheave by this grooving projection, in addition, preferably also be provided with grooving projection between two groovings, can effectively prevent rope from being moved with it by rope sheave cassette tape, and cause rope to be wound around or stuck situation on rope sheave, the medial surface of described rope sheave is provided with concave, convex tooth, and the concave, convex tooth of two medial surfaces is concave, convex correspondence, that is, recessed tooth is facing to double wedge, and double wedge is facing to recessed tooth.Anti-slip veins, the anti-slop serrations of described concave, convex tooth and routine are completely different, and this recessed tooth and double wedge are trapezoidal, and the upper surface of described double wedge, the bottom surface of recessed tooth are preferably designed for planar structure, are preferably designed for arc-shaped transition between recessed tooth and double wedge.The selection of above-mentioned concave, convex odontoid is through lot of experiments, research draws, this concave, convex tooth designs, can make the section cord be embedded in rope sheave that intensive smallly to turn to occurs, obviously can strengthen the frictional force between rope and rope sheave, effectively stop the relative motion between the two, that is, skidding is stopped.
For achieving the above object, the selection of the diameter of described rope and the setting of rope sheave two medial surface angle also very important.The rope diameter that existing high level quick falling escape apparatus is conventional is 9-13mm, length is determined according to using height, be generally 60 ~ 120 meters, consider intensity (security) and the volume and weight (portable degree) thereof of rope, inventor preferentially selects 9-10mm specification rope, can bear the safe handling of personnel within gross weight 200kg.
Inventor, in the use to existing high level quick falling escape apparatus and in studying, finds that the angle between its rope sheave two medial surface is bigger than normal, is about 28-30 °.When this angle is more than or equal to 28 °, even if select thicker rope, also inevitable relative motion between rope and rope sheave is (when angle is bigger than normal, rope reduces the normal pressure of rope sheave medial surface, and frictional force reduces, and therefore easily produces relative motion), namely, cannot ensure user's uniform descent, the lighter causes the discomfort of user, and severe one may cause somatic damage to user.Particularly when using its enhanced feature, this angle defect brought bigger than normal is more obvious, when this angle is more than or equal to 28 °, almost cannot mention the personnel that gross weight is 60kg, even 50kg is very difficult, this weight is obviously on the low side relative to the body weight of normal staff, not only expends time in, energy, also likely causes and rescues unsuccessfully.As everyone knows, work high above the ground personnel have the safety measures such as safety belt with it, once meet accident, be connected with safety belt stop dropping to detain just can be worked, be suspended from and prevent from midair falling, and staff is now due to reasons such as scaring, the powerful impulsive forces that stops falling, and the phenomenons such as faint or stupor can occur, need to save fast to take other treatment measures, incur loss through delay the best time of suing and labouring and probably cause serious consequence.Therefore, select suitable rope sheave angle angle very important.
The angle of two medial surfaces of described rope sheave is 22-25 °, the rope sheave of this angular range just makes rope be embedded in rope sheave about 1/3 ~ 1/2, even if two prompt drop personnel use simultaneously, the degree of depth that rope embeds rope sheave is about 2/3 of rope, also can not occur angle less than normal time rope be absorbed in the phenomenon not easily pulled out inside rope sheave completely, although this phenomenon can not affect decrease speed, but very serious wearing and tearing can be produced to rope, add the cost changing rope, or there is the hidden danger causing personnel's actual bodily harm when being negligent of changing.The selection of this angle more can make lifting weight reach 200kg, can meet the lifting of 3 normal type personnel completely.
For reducing rope in entry and exit (namely, grooving) shaking amplitude at place, the inner side of described large Hatch Board is provided with the limited block corresponding to grooving, (namely this limited block is preferably in vitro formula structure, this limited block and large Hatch Board are through fitting together), this design more casting integrated formula structure is easier, convenient in processing.When large Hatch Board and casing affixed after, described limited block is fastened in grooving, makes rope position substantially fixing.In the process of prompt drop, described rope is limited in the scope of design all the time.
