Abstract
A sector gate opening and closing device for an underground ore storage bin comprises a sector gate and a chute mouth, wherein a proximity switch is installed on the front part of the sector gate and is connected with an intermediate relay, and a normally-open contact of the intermediate relay is connected with a signal circuit of a hoist. The sector gate opening and closing device is used for solving the problem that the sector gate and the chute mouth are not tightly closed with each other, the sector gate, the chute mouth and the hoist are interlocked with each other during the operation, a hoisting bucket is prevented from scratching and colliding with the sector gate, the interaction control of a hoist electrical system is realized, an ore loading system can safely and reliably work, production interruption and equipment accidents are avoided, and the device is mainly applied to an underground ore loading system. Moreover, the device is simple in structure and easy to carry out, has high control precision, good stability, also has the functions of water proof, moisture proof, smashing resistance and the like and is used for solving the problem of the existing ore loading technology, the daily maintenance workload is reduced, the equipment failure rate is reduced, and the stability and continuity of a production system are ensured.
Description
Technical field
The utility model relates to ore storage bin sector gate field, down-hole, specifically a kind of down-hole ore storage bin sector gate closing device.
Background technology
The metering ore storage bin of underground mines is installed in six stage casings, down-hole.The lifting skip bucket is opened sector gate after transferring and putting in place, slips into the lifting skip bucket by the ore of belt running in the metering ore storage bin, and sector gate closes, and the operative employee sends starting signal, the gig entry into service.The shortcomings such as sector gate is opened and closure, operates cylinder by the operative employee and controls, and whether the sector gate folding condition puts in place, is mainly controlled by two iron-clad travel switches, and is poor owing to iron-clad travel switch control accuracy, that fault rate is high, mechanism is fragile.Sector gate often occurs and slip the closed phenomenon not in place of mouth, the front portion and the mutual scratching of lifting skip bucket that cause sector gate, damage sector gate and skip bucket, perhaps occur having ore to block in the sector gate mechanism, causing sector gate and slipping has the space between the mouth, and the ore in the metering ore storage bin of packing into slips out from the space, cause the bottom fine ore to stop up, when serious two tail ropes of skip bucket bottom are intertwined, need to rush to repair, production can not normally be carried out.
The utility model content
Technical problem to be solved in the utility model is that sector gate a kind of simple in structure, easy enforcement that provides with the closed problem not in place of slide mouth, the down-hole ore storage bin sector gate closing device that control accuracy is high, stability is good in the prior art are provided.
The utility model content is achieved through the following technical solutions:
A kind of down-hole ore storage bin sector gate closing device comprises sector gate, slips mouth, in the front portion of described sector gate one approach switch is installed, and described approach switch connects an intermediate relay, will connect normal battle of described intermediate relay the gig signal circuit.
On the described slide mouth iron plate is set, described iron plate is positioned at the bottom of approach switch, and the area of described iron plate is greater than the area of approach switch bottom sensitive surface.
The utility model adopts the front portion of sector gate that one approach switch is installed, and intermediate relay of approach switch control will seal in normal battle of intermediate relay the gig signal circuit.At the slide mouth one iron plate is set simultaneously, iron plate is positioned at the bottom intermediate relay of approach switch.This structure has solved sector gate and has slipped the not tight problem of mouth closure, realized the interlocked relationship between sector gate, slide mouth, the gig running three, avoided promoting the phenomenon of skip bucket and the mutual scratching of sector gate, realized that the gig electric system controls mutually, make dress ore deposit security of system reliable operation, avoid producing and interrupt and the generation accident, be mainly used in the system of dress ore deposit, down-hole.Simultaneously apparatus structure simple, implement easily, control accuracy is high, stability is good, also have waterproof, protection against the tide, the anti-function such as pound, solved the problem that existing dress ore deposit technology exists, reduced the line service amount, reduce equipment failure rate, guaranteed stability and the continuity of production system.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model working state figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, 2, a kind of down-hole ore storage bin sector gate closing device comprises sector gate 3, slide mouth 5, in the front portion of sector gate 3 TL-N20MY1 type approach switch 4 is installed.Approach switch 4 will access the gig signal circuit the normal battle of intermediate relay 9 by intermediate relay 9 of wire control.In order better to make approach switch 4 work, slipping iron plate 8 of mouth 5 welding, iron plate 8 is positioned at the bottom of approach switch 4, and the area of iron plate 8 is greater than the induction area of approach switch 4 bottoms.
During use approach switch 4 and intermediate relay 9 are in series and pass into the 220VAC power supply, adjust the actual induction distance of iron plate 8 and sector gate 3, make sector gate 3 and slip mouth 5 closures when putting in place, approach switch 4 could be worked.By intermediate relay 9 of approach switch 4 controls, normal battle and the gig signal circuit of intermediate relay 9 are in series, two signal lamps are installed again, make traffic light system go out the accurate location of sector gate 3, use in addition the existing condition of relay auxiliary point and signal lamp co-controlling sector gate 3, avoid promoting the possibility of skip bucket 6 and sector gate 3 mutual scratchings, made dress ore deposit security of system reliable operation, guaranteed the integrity of equipment and the stability of production.
