Abstract
A kind of single rope winding hoist rope-loosing protection device, relates to a kind of fender guard of monitoring main hoisting cable slack rope.For improving mine hoist safety reliability, the technical solution adopted in the utility model is: comprise electric conductor and mounting bracket, electric conductor is fixed on mounting bracket by the U-shaped card at two ends, insulation cushion rubber is housed between electric conductor and U-shaped card, electric conductor below steel rope, electric conductor is fixed with wiring between elevator drum and head sheave.This use is novel is simple and easy to use, of good reliability, has with low cost, without the need to transforming the advantage of existing equipment.Drum winding winch arranges rope-loosing protection device, and access security loop, the energy auto-breaking when steel wire rope looseness is also reported to the police.
Description
Technical field
The present invention is under the jurisdiction of gig technical field of automation, relates to a kind of fender guard of monitoring main hoisting cable slack rope.
Background technology
Former rope-loosing protection device is arranged on cylinder rope stretching side; there is action when main electromotor fault causes slack rope insensitive; even if steel rope is lax also do not reach fender guard; the present invention is devised for single rope winding hoist; be arranged on rope stretching window place in hoist house, as long as gig generation slack rope phenomenon, the winch that is reflected to that can be sensitive is protected in electric-control system; and alarm and implement brake-contracting cut-off stop, improve the safe operation coefficient of winch.
Hoist control system Installation and Debugging complete, and cylindrical drum hoist rope creep protection is the important fender guard of in elevator system, especially even more important in mine shaft hoist system.According to statistics, vertical drum winding system slack rope fault often occurs, if can not be taked actv. emergency trouble shooting measures by Timeliness coverage, will cause very serious accident.Therefore, clear stipulaties in " safety regulations in coal mine ": " drum winding winch must arrange rope-loosing protection device, and access security loop, the energy auto-breaking when steel wire rope looseness is also reported to the police ".
Summary of the invention
For improving mine hoist safety reliability, the technical solution adopted in the utility model is:
A kind of single rope winding hoist rope-loosing protection device; comprise electric conductor and mounting bracket; electric conductor is fixed on mounting bracket by the U-shaped card at two ends; insulation cushion rubber is housed between electric conductor and U-shaped card; electric conductor below steel rope, electric conductor is fixed with wiring between elevator drum and head sheave.
According to described single rope winding hoist rope-loosing protection device; described electric conductor and the spacing of steel rope are 5 ~ 15cm; steel rope is connected with one end of relay, and the other end access power supply of relay, the open contact of relay is connected with gig PLC input interface.
This use is novel is simple and easy to use, of good reliability, has with low cost, without the need to transforming the advantage of existing equipment.

Detailed description of the invention
Embodiment
Utilizing at Xin An coal industry company main shaft cylindrical drum hoist is example, has installed slack rope device additional at Steel wire rope discharge mouth, and the energy auto-breaking when steel wire rope looseness is also reported to the police.Steel rope is in operation, and is sealed in safety return circuit, achieves omnidistance rope creep protection, avoids because protecting malfunctioning and accident that is that occur.Device uses 1.2 meters long diameter 20mm iron pipes, and two ends use diameter 80mm insulated enclosure cushion rubber to fix iron pipe, and iron pipe does not directly access with fixing U-shaped card 4, and U-shaped card 4 is directly fixed on angle bar, iron pipe accesses the side, loop of rope creep protection relay.
As shown in Figure 1; in time promoting thing 8 and block or directly stop; or steel rope 2 breaks stock when causing steel wire rope looseness; or promote time thing 8 falls and cause relaxing; when steel rope 2 occurs lax; the rope creep protection relay of access PLC forms path adhesive by steel rope ground connection, and relay K A contact seals in safety return circuit, achieves omnidistance rope creep protection.
Slack rope device has been installed additional at Steel wire rope discharge mouth through work place study.Device uses 20mm iron pipe as electric conductor 6, and two ends use diameter 80mm insulation cushion rubber 5 to fix iron pipe, and iron pipe does not directly access with U-shaped card 4.Charged body 6 is fixed on mounting bracket 3 i.e. angle bar by U-shaped card 4, and the bolt 9 on iron pipe is by one end of wiring 10 cut-in relay power supply.Such electric conductor 6 is just connected on the side, loop of rope creep protection relay.Steel rope 2 is connected with relay one end, relay other end access power supply.
As shown in Figure 4, steel rope 2 and electric conductor 6 can be equivalent to K switch, and steel rope 2 contact relay KA, electric conductor 6 connects power supply one end.As Fig. 1, when steel rope 2 occurs lax (dotted line represent be lax steel rope), steel rope 2 is inevitable saggingly to be contacted with electric conductor 6, and the rope creep protection relay of access PLC defines path adhesive by steel rope 2.Relay K A contact seals in safety return circuit and is namely connected with PLC input interface; PLC judges, and then controls gig action by output interface, and then achieves omnidistance rope creep protection; achieve omnidistance rope creep protection, avoid the insensitive phenomenon of action of original old-fashioned slack rope device.
