Abstract

The utility model discloses a protective device of tail ropes of an elevator, which comprises an isolation steel beam, a steel wire draw rope, a pulley set, a counter weight block and an approach switch. The steel wire draw rope is horizontally arranged right under the isolation steel beam, one end of the steel wire draw rope is fixedly connected with a bearing base at the lower portion of the isolation steel beam, and the other end of the steel wire draw rope is drawn to a well head through the pulley assembly. The counter weight block is hung at the tail end of the steel wire draw rope, and the approach switch is arranged close to the counter weight block and electrically connected with a programmable logic controller (PLC) of the elevator. After the protective device of tail ropes is installed, major faults caused by twisted ropes of the tail ropes, twisted ropes of sundries and the like can be effectively avoided, thereby ensuring safety of a hoisting system. Working conditions of the tail ropes can be effectively detected, tail rope faults can be prevented ahead of time, and huge loss such as equipment faults, injury on people and suspend production caused by the rail rope faults is effectively avoided.

Description

Gig tail rope fender guard

Technical field

The utility model relates to mine mining gig technical field, relates in particular to a kind of gig tail rope that prevents and is broken or twist disconnected fender guard.

Background technology

At present, the vertical shaft hoisting device that adopt in most of mines, the tail rope of gig is all longer, in promoting operation because the spinner et out of order that the lifting container bottom links to each other with tail rope, cause tail rope energetically, winding; The foreign material that perhaps drop from upper wellbore cause tail rope strand to be turned round, and perhaps tail rope rocks excessively in promoting operation, and tail rope is suspended on pit shaft or shaft bottom girder steel, the anchor pole, all the accident that tail rope is broken can take place.The operation quality of tail rope affects the safe operation of gig, in case tail rope is broken or malicious event, will directly cause system to stop production, and after having an accident, the equipment repairing time is long, and task amount is big, has a strong impact on the normal operation of production.

The utility model content

The purpose of the utility model be to provide a kind of simple in structure, can effectively prevent the gig tail rope fender guard that tail rope is broken.

For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:

A kind of gig tail rope fender guard; Comprise the isolation girder steel; Also comprise steel wire tow line, assembly pulley, clump weight and near switch, said steel wire tow line be set in parallel in isolate girder steel under, an end is captiveed joint with the supporting base of isolation girder steel bottom; The other end draws to the well head place through assembly pulley, and is hung with clump weight at the steel wire tow line end; Be provided with near the said clump weight near switch; Saidly be electrically connected with the programmable logic controller (PLC) PLC of gig near switch.

Said assembly pulley comprises girder steel place first fixed pulley that is fixedly connected on said well head and second fixed pulley that is fixedly connected on said isolation girder steel below.

Said first fixed pulley is 1～2.

Said steel wire tow line is provided with plastic protective sleeve.

The above-mentioned gig tail rope fender guard that the utility model provides when gig moves, is turned round or other situation energetically in case strand appears in tail rope after installing; Steel wire tow line pulling clump weight; Detect near switch and will send alerting signal less than clump weight, and abnormal signal is sent to the programmable logic controller (PLC) PLC of gig, gig is out of service; Can effectively avoid because the major failure that tail rope twisted rope, foreign material twisted rope etc. cause is guaranteed the safety of elevator system; Effectively detect the working condition of tail rope, prevent the tail rope fault in advance; Effectively avoid because the massive losses that the equipment breakdown that the tail rope fault causes, personnel's injury and stopping production are caused.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1-fag end snap close, 2-isolates girder steel, and 2 '-supporting base, 3-tail rope, 4-steel wire tow line, 5-first fixed pulley, 5 '-the second fixed pulley, 6-well head, 7-clump weight, 8-be near switch, the 9-support.

The specific embodiment

Below in conjunction with specific embodiment and accompanying drawing thereof the utility model is described further.

Gig tail rope fender guard as shown in Figure 1, that the utility model provides is in the bottom of gig pit shaft; About 1 meter, gig tail rope 3 tops; Be welded with tail rope and isolate girder steel 2, isolating 0.5 meter horizontal steel wire tow line 4 that draws a band plastic protective sleeve under the girder steel 2, steel wire tow line 4 be positioned at tail rope isolate girder steel 2 under; Can prevent that the coating plastic protecting sleeve possesses waterproof, rust proof function on the steel wire tow line 4 because of other foreign material of upper wellbore fall down the misoperation that causes.

One end of steel wire tow line 4 is fixed on the supporting base 2 ' of isolating girder steel 2 belows through fag end snap close 1; The other end through be welded on second fixed pulley 5 ' of isolating girder steel 2 belows, two first fixed pulleys 5 that are welded on the girder steel place of well head 6 draw to well head 6 places, and are hung with clump weight 7 at the end of steel wire tow line 4; Be provided with near switch 8 near the clump weight 7, be used for detecting the action situation of clump weight 7; Be fixedly connected on the support 9 near switch 8; Be electrically connected with the programmable logic controller (PLC) PLC of gig; Detection signal near switch 8 flows to gig programmable logic controller (PLC) PLC, and programmable logic controller (PLC) PLC sends action commands such as warning, parking to actuating unit.

Working process is following:

When gig moves, strand occurs and turn round or other situation energetically in case the tail rope 3 of gig occurs, or tail rope 3 is isolated girder steel 2 apart and crossed when near; Steel wire tow line 4 just can be pulled, and steel wire tow line 4 terminal clump weights 7 are raised, and detect less than clump weight near switch 8; Send alerting signal at once; And abnormal signal flowed to the main control PLC of gig, gig is out of service immediately, takes place thereby avoid taking place the accident that tail rope broken or destroy.

What should explain at last is: above embodiment is only in order to being illustrated more clearly in the utility model, and and the described technical scheme of unrestricted the utility model.All do not break away from the technical scheme and the improvement thereof of utility model flesh and blood and scope, and it all should be encompassed in the claim scope of the utility model.
