Abstract
A coiling block is hung in a box body, on one end of the coiling block is set with a ratchet wheel and driving gear, braking catch pawl is set on its side. One end of the shaft is stretched out of the box body, the shaft is fixed with a rope wheel. The tension rope of balance weight is wound on the rope wheel. During lifting an object, the gravity of balance weight causes the rope wheel and coiling bloke to rotate and makes the safty rope tighten on the coiling block. In case the descending velocity of the lifting object exceeds a certain value, the catch pawl will brake the ratchet wheel, the safty rope on the coiling block will hang and stop the drop of object.
Description
A kind of falling proof device, particularly low clearance that relate to lifting means, the falling proof device of Ti Shenging at a slow speed.
Lifting means all should have the fall arrest safety device, does the fall arrest insurance as speed limiter safety tongs system on elevator, the elevator.But many low clearances non-lifting means that is written into of lifting at a slow speed do not have this fall arrest safety device, as integral-scaffold lifting means for building, the gig of low clearance etc.Reason has two aspects: one is to use the people in order to save money and to dislike trouble, and the 2nd, this desirable without comparison class safety device.Though the accident of this respect is rare, loss that causes and influence are serious.
The present invention will provide a kind of falling proof device that is applicable to low speed, low clearance lifting means.
The present invention realizes by following step.
Make reel with one section pipe, make spiral drum slot on the cylindrical, seal at two, and axle is worn by central authorities.One end of reel is equipped with ratchet and common transmission gear, and reel crouches and to be contained in the casing that a prodigiosin enough is draped, and adorns ratchet on the other box body wall of the wheel rim of ratchet, and is furnished with click spring and ratchet driving lever.One tool centrifugal speed limiter is contained in the casing outside of ratchet one end, and the gear on its spindle nose stretches into from the hole of box body wall, and with the gear mesh that is contained on the reel end face, its poke rod is connected with the ratchet driving lever.
A binding of safety rope is raised thing, and tie on reel the other end.The tensioning knot that has hung counterweight is around one of reel, and the gravity of counterweight makes reel direction of rotating and the gravity that is raised thing make the direction of reel rotation opposite., of reel is separated disorderly on reel for fear of safety rope and tensioned lines, for knot around the tensioned lines special use, perhaps establish the rope sheave of knot in addition around tensioned lines, be fixed on the reel, make rope sheave become the some of reel.
When the lifting thing was raised, the gravity of counterweight rotated reel through tensioned lines, safety rope is received on the reel, and keeps tensile force.When being raised the descending speed overshoot value of thing, centrifugal speed limiter moves, and its poke rod drives the ratchet driving lever and makes ratchet and ratchet engagement, brake drum, and being hovered by safety rope is raised thing.
For the lifting at a slow speed of low clearance, can directly press ratchet that ratchet is made the reverse direction braking anti-falling by click spring without centrifugal speed limiter.
This falling proof device has simple for production, easy to use, high reliability features are applicable to the lifting insurance of important item.Be used for the elevator of low clearance at a slow speed, can replace velocity limiter safety tongs drop preventer, thereby separate the fall arrest problem of the elevator that promotes by winch of never establishing machine room.
The place of and tensioned lines inconvenience heavy in establishing can provide torque for reel with electromagnetic mechanism, and replacement counterweight, rope sheave when being raised thing and being raised, tighten up safety rope.For example the DC torque motor that power is suitable is connected with reel, constitutes interlock.Because this class motor can be in work under the stall state for a long time, holding torque can not burn out.The torque that electromagnetic mechanism applies to reel can be by the form transmission of friction lining with friction force, when torque is excessive, and friction lining slipping protection electromagnetic mechanism.
Fig. 1 is the profile diagram of falling proof device
Fig. 2 is the constructional drawing of falling proof device
Crouch in casing (1) lining that a prodigiosin is draped and to adorn a reel (2) that has only positive and negative spiral drum slot, ratchet (3) is contained in an end of reel (2), of the axle of the reel that reaches the casing outside, fix a rope sheave (4), it is other that braking ratchet (5) is contained in ratchet (3), its driving lever (6) stretches out in box body hole, and click spring (7) presses ratchet to contact with ratchet.Centrifugal speed limiter (8) is contained in the casing outside, and the gear on its spindle nose stretches into casing and gear (9) engagement that is contained in reel one end, and its poke rod (10) is connected with ratchet driving lever (6).One of two safety ropes (11) ties respectively around about the reel, and the other end links and is raised thing (12).Tensioned lines (14) knot that links counterweight (13) on rope sheave (4), its around to safety rope to reel around to opposite.Be raised hoisting rope (15) that thing (12) is subjected to winch through deflection sheave (16) when upwards promoting, counterweight (13) descends, and its gravity rotates through tensioned lines (14) bull wheel (4), makes reel tighten up safety rope (11).When being raised the super specified value of descending speed of thing, centrifugal speed limiter (8) moves, and poke rod (10) rotates, and makes ratchet (5) and ratchet engagement, and reel is braked, and safety rope hovers and is raised thing.
For the bigger lifting of speed, safety rope be raised the buffer body of should connecting between the thing, to alleviate the impact of promptly hovering.
