Abstract
The utility model discloses a belt stay cord switch switching state display device, the device include belt stay cord switch body, belt stay cord switch body inserts belt conveyor power supply line, establish ties on the belt stay cord switch body and can show the display of on-off state through the pilot lamp. The utility model discloses avoided present belt conveyor stay cord switch not from taking disconnection, closed indicating device, whether the maintainer can't confirm the stay cord switch and reliably break off, the maintenance of the belt conveyor who gives maintains the problem of bringing.
Description
Technical Field
The utility model relates to a belt conveyor technical field, in particular to belt stay cord switch switching status display device.
Background
A pull-cord switch of a belt conveyor is a safety protection device for emergency shutdown of the belt conveyor, and is suitable for belt conveyors used in industries such as coal, metallurgy, electric power, chemical industry, traffic, cement, wharfs and the like. The pull-cord switch is composed of a pull rod, a reset handle, a cam, a lock groove, a microswitch and the like. The pull rope switches are arranged on the machine frames on the two sides of the belt conveyor, and the switches are connected by steel wire ropes along the two sides of the belt conveyor. When the conveyer belt equipment has an emergency accident, the steel wire rope is pulled at any position along the line on site, the steel wire rope pulls the driving arm to rotate, the transmission shaft drives the torsion spring to enable the precision cam to displace, and the control circuit is driven to enable the conveyer to stop running. According to safety regulations, a belt pull-cord switch is required to be installed every 20 meters on a belt conveyor, so that 5-6 pull-cord switches are usually installed on a long belt, and in the process of parking, when an overhaul worker temporarily overhauls the belt conveyor, the overhaul worker can pull the pull-cord switch open for safety to ensure that the belt conveyor cannot be started by other people, the pull-cord switch is not provided with an indicating device for disconnection and closing, and the overhaul worker cannot confirm whether the pull-cord switch is reliably disconnected; in addition, when an operator turns on the equipment, if one of the pull-cord switches is disconnected, the equipment cannot be turned on, the pull-cord switches can be turned off and on one by one to check, and the belt pull-cord switches are not turned off and on until the belt conveyor can be turned on, so that the safety of maintainers cannot be completely guaranteed, the operators also need to check one by one, time is delayed, and the labor intensity is increased.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a belt stay cord switch on-off state display device can avoid present belt conveyor stay cord switch not to take disconnection, closed indicating device certainly, and whether the maintainer can't confirm the stay cord switch reliably breaks off, and the maintenance of the belt conveyor who gives maintains the problem of bringing.
In order to achieve the above object, the technical solution of the present invention is specifically as follows:
the utility model provides a belt stay cord switch on-off state display device, includes belt stay cord switch body, belt stay cord switch body inserts belt conveyor power supply line, establish ties on the belt stay cord switch body and can show the display of on-off state through the pilot lamp.
The display capable of displaying the on-off state through the indicating lamp comprises a relay coil, a relay normally open contact and an indicating lamp, wherein the relay coil is connected with the belt pull rope switch body in series, the relay normally open contact is connected with the relay coil in parallel, and the indicating lamp is connected with the relay normally open contact in series.
The indicator light is arranged on the electrical box.
The utility model has the advantages that: the utility model discloses a series connection can show the display of on-off state through the pilot lamp on the belt stay cord switch body, when belt stay cord switch body is closed to the belt conveyor power supply, can show the pilot lamp on the display of on-off state through the pilot lamp and light, show the state that the belt conveyor can be opened for supplying power at this moment for the staff, when can show the indicator lamp on-off state's display through the pilot lamp and extinguish, show the belt conveyor and be the outage off-state at this moment for the staff, therefore, the staff can know whether the belt conveyor has electricity as long as observe whether the pilot lamp on the display of on-off state can be shown through the pilot lamp, simple and clear, when having improved work efficiency, avoided again because of misoperation the danger that brings for personnel, wherein, can show the display of on-off state through the pilot lamp is through establishing ties the coil on the belt stay cord switch body, the relay normally open contact that connects in parallel on the relay coil, the series connection pilot lamp on the relay normally open contact, when the closed circular telegram of belt stay cord switch body, the relay coil is promptly electrified, and the closed circular telegram of relay normally open contact, the pilot lamp lights, can be seen by operating personnel very easily for making the pilot lamp, and the pilot lamp setting is on the electric box.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, a belt stay switch on-off state display device, including belt stay switch body 1, belt stay switch body 1 inserts belt conveyor power supply line, the last series connection of belt stay switch body 1 can show the display of on-off state through the pilot lamp, the display that can show on-off state through the pilot lamp includes relay coil 2, relay normally open contact 3 and pilot lamp 4, relay coil 2 and belt stay switch body 1 are established ties, the last parallelly connected relay normally open contact 3 of relay coil 2, series connection pilot lamp 4 is gone up to relay normally open contact 3, pilot lamp 4 sets up on the electric box.
The utility model discloses when using, all install on all belt stay cord switch bodies 1 along the line on the belt conveyer the utility model discloses, when the closed circular telegram of belt stay cord switch body 1, relay coil 2 has got the electricity, simultaneously, because the electricity that gets of relay coil 2, relay normally open contact 3 has got the electricity actuation, pilot lamp 4 has got the electricity and lights, when belt stay cord switch body 1 breaks off, relay coil 2 loses the electricity, simultaneously, because relay coil 2 loses the electricity, relay normally open contact 3 loses the electricity disconnection, pilot lamp 4 extinguishes.
When in the belt conveyor parking process, the maintainer overhauls the during operation temporarily on the belt conveyor, the maintainer is as long as each pilot lamp 4 who corresponds on observing the electric box lights, can judge whether this belt conveyor's that corresponds belt stay cord switch body 1 opens, when operating personnel is opening equipment, only observe pilot lamp 4 on the electric box, can know all belt stay cord switch bodies 1's on-off state, avoid examining one by one, reduce intensity of labour, guarantee operation safety.
