Abstract

The invention discloses a manual-automatic integrated fixed baffle chair device of a descending runaway of a mine ropeway, comprising a suspension bracket. A fixed shaft is mounted on the suspension bracket and provided with a shaft sleeve which is fixed by nuts, a baffle is mounted at the lower side of the shaft sleeve, a poker block is mounted at the upper side of the shaft sleeve, a traction electromagnet is mounted on the suspension bracket, the traction electromagnet pull rod is connected with the poker block, the electromagnet can be controlled through an overrunning safe protective circuit, a manual switch of the overrunning safe protective circuit is controlled through a stay cord, and a speed sensor is arranged at the riding wheel side. The invention has the advantages that because the baffle is controlled by the electromagnet, the baffle is pulled up by the electromagnet without preventing a movable rope clip from passing when the mine ropeway runs normally; and when the power failure occurs in the operation process of the mine ropeway to cause runaway, and a suspension chair in the descending direction rapidly slide downwards under the action of gravity, the baffle is pulled up by the electromagnet and moves downwards to be clamped on a wire cable when the speed detected by the speed sensor exceeds a safety value so as to prevent the movable rope clip from sliding downwards and avoid the casualty accidents of persons sitting on the suspension chair.

Description

The descending driving auto-manual of mining cableway fixed type retaining chair apparatus

Technical field

The present invention relates to a kind of mining cableway driving retaining chair apparatus.

Background technology

Mining cableway is in operational process, because power failure, the chair lift of down direction slides the driving phenomenon that causes downwards fast under the effect of gravity, cause the generation of travelling people person's casualty accident.

Summary of the invention

The purpose of this invention is to provide the descending runaway retaining of a kind of mining cableway chair apparatus.

The objective of the invention is to realize in the following way: the descending driving auto-manual of a kind of mining cableway fixed type retaining chair apparatus; comprise suspension bracket; anchor shaft is housed on suspension bracket; axle sleeve is housed on anchor shaft; axle sleeve is fixed with nut; downside at axle sleeve is equipped with baffle plate; upside at axle sleeve is equipped with pulling block; electromagnet is housed on suspension bracket; the electromagnet pull bar is connected pulling block; electromagnet can be by the safety protective circuit control of overrunning, and the hand switch of the safety protective circuit of overrunning is controlled by stay cord, is provided with speed sensor in the support roller side.

The described safety protective circuit of overrunning comprises PLC; relay; PLC connects AC127V input power supply; the speed that connects PLC input terminal X1 detects 2 pin with speed sensor; 3 pin of speed sensor connect the COM end of PLC; 1 pin of speed sensor K1 meets the 24V+ of PLC; PLC lead-out terminal Y0 succeeds the A2 pin of electrical equipment J1 coil; COM0 connects the COM end of PLC; the A1 pin of relay J 1 coil meets the 24V+ of PLC; the moving switch of 11 pin catcher of J1 open contact is often opened; public pin 2 pin of normally closed contact; 14 pin of J1 open contact meet the 24V+ of PLC; 2 pin of electromagnet YV1 join with 3 pin of hand switch (14) normally closed contact and 1 pin of open contact respectively, and 1 pin of electromagnet connects the COM end of PLC.

The present invention has following beneficial effect, because baffle plate is to pass through magnet control, when mining cableway normally moves, electromagnet is with the baffle plate pull-up, not influencing movable rope clamping device passes through, when power failure appears in mining cableway in operational process, when driving takes place, the chair lift of down direction slides downwards under the effect of gravity fast, when surpassing safety value by the speed sensor detection speed, electromagnet pulling baffle plate, baffle plate moves downward and is stuck on the steel rope, can prevent that movable rope clamping device from sliding downwards, avoids taking advantage of the generation of the personnel casualty accidents of a chair lift.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; the descending driving auto-manual of a kind of mining cableway fixed type retaining chair apparatus; comprise suspension bracket 1; anchor shaft 5 is housed on suspension bracket 1; axle sleeve 7 is housed on anchor shaft 5; axle sleeve 7 usefulness nuts 10 are fixing; downside at axle sleeve 7 is equipped with baffle plate 8; upside at axle sleeve 7 is equipped with pulling block 9; electromagnet 11 is housed on suspension bracket 1, and electromagnet 11 pull bars are connected pulling block 9, and electromagnet 11 can be by the safety protective circuit control of overrunning; overrun the hand switch 14 of safety protective circuit by stay cord 13 controls, be provided with speed sensor 12 in support roller 2 sides.

As shown in Figure 5; The safety protective circuit of overrunning comprises PLC; relay; PLC connects AC127V input power supply; the speed that connects PLC input terminal X1 detects 2 pin with speed sensor 12; 3 pin of speed sensor 12 connect the COM end of PLC; 1 pin of speed sensor K1 meets the 24V+ of PLC; PLC lead-out terminal Y0 succeeds the A2 pin of electrical equipment J1 coil; COM0 connects the COM end of PLC; the A1 pin of relay J 1 coil meets the 24V+ of PLC; the moving switch 14 of 11 pin catcher of J1 open contact is often opened; public pin 2 pin of normally closed contact; 14 pin of J1 open contact meet the 24V+ of PLC; 2 pin of electromagnet YV1 join with 3 pin of hand switch 14 normally closed contacts and 1 pin of open contact respectively, and 1 pin of electromagnet 11 connects the COM end of PLC.

Mining cableway is normally in service, when PLC surpasses the PLC programmed values by speed sensor 12 detected running velocitys, PLC mouth YO control relay J1 gets, control relay J1 adhesive, all electromagnet 11 that the tunnel is along the line, the parking of the mining cableway of automatic guidance, thus reach protection passenger purpose of safety; When 14 actions of somewhere along the line, tunnel hand switch, control electromagnet 11 gets electric, manually controls the parking of mining cableway, also reaches the mining cableway passenger purpose of safety of protection protection.
