Abstract
The utility model belongs to a protective device which is matched with a belt type conveyor and can display states. The protective device is composed of a sounder, indicator lights, a pull wire switch and an acoustooptic state display. The utility model is characterized in that two leading-in wires which are connected with an alternating current A1 are connected two announcing indicator lights which are connected in parallel and simultaneously, the two leading-in wires enters the acoustic horn of the sounder through a transformer and a bridge type rectification and filter circuit. An alternating current A2 is connected with a motor siren and a state indicator light through pull rope switch contact points which are provided with two output ends a and b and connected in parallel. The utility model can realize starting announcing signal indication, state display and concentrated pull rope warning management.
Description
The utility model belongs to fender guard supporting with belt conveyer and that but state shows.
At present; what be used for belt conveyer protection along the line has pull switch, starting approaching signal and a Converting terminal case etc.; they all have separately circuit structure and electric power system; independently be installed in separately on the frame along the line of belt conveyer, make that the belt conveyer corollary apparatus along the line of operation is messy, complicated, make troubles to maintenance; speed of application is slow; maintenance management is very inconvenience also, and the conveyer reliability of operation can not be guaranteed, and is difficult to make the work efficiency of conveyer further to improve.
The purpose of this utility model is the shortcoming at above-mentioned existence, provides a kind of easy for installation, simple in structure, the comprehensive protector of being convenient to keep in repair.
The purpose of this utility model is achieved in that it is made up of sounder, indicator lamp, pullswitch and acousto-optic status displays, it is characterized in that two inlet wires that link to each other with alternating current A1, connect two advance notice indicator lamps (4) in parallel, simultaneously through voltage transformer (1), bridge rectifier and filter circuit (2) loudspeaker (3) to sounder; In parallel pull switch (5) contact of alternating current A2 through being provided with two mouth a, b connects electric whistle (7) and status indicator lamp (6).When monitored control system sent adhesive tape plan cranking signal, power supply was logical, and loudspeaker (3) ring, and advance notice indicator lamp (4) is bright; After pull switch (5) pulling, electric whistle (7) rings, and status indicator lamp (6) is bright.
The utility model is supporting to belt conveyer appropriate location along the line, can realize starting the approaching signal indication, and state shows, the centralized management that stay cord is reported to the police.Be convenient to conveyer reliability of operation and work efficiency be improved to belt conveyer operation conditions cross-check sum operating troubles maintenance along the line.It is simple in structure, and is easy for installation, and speed of application is fast, for ease of maintenaince.
Description of drawings:
Fig. 1 is schematic circuit diagram of the present utility model;
Fig. 2 is the utility model body structure scheme drawing;
Fig. 3 is the lateral plan of Fig. 2.
Narrate below in conjunction with accompanying drawing: connect 220 volts or 380 volts from the visible alternating current A1 of Fig. 1 is optional, alternating current A2 is 220 volts.Loudspeaker among Fig. 1 (3), advance notice indicator lamp (4), status indicator lamp (6) and electric whistle (7) all are fixed on the cabinet panel; Voltage transformer (1), turnover line apparatus and terminal row (9) are fixed on the box house support.Voltage transformer (1) is reduced to 24 volts with 380 volts or 220 volts of alternating-current voltage/AC voltages; power to series connected 12V loudspeaker behind the rectifying and wave-filtering; terminal row (9) is as the circuit switch of this device or belt conveyer other fender guard along the line, and its quantity determines the belt conveyer concrete installation situation of comprehensive protector along the line.Pullswitch (5) is located in the housing (8) on casing top, and itself mainly is made of traction crank, reseting handle, reaction spring, micro-switch etc., and it can utilize existing pullswitch.Microswitch contact in the pullswitch (5) links to each other with terminal row in the casing through lead.Casing (11) and chamber door (12) adopt metal or non-metallic material (as plastics) to make, chamber door is arranged at the front of casing, indicator lamp (4) is arranged at side panel and front plate intersects on the inclined-plane of certain angle, and in positive and side all as seen optional 40～60 degree of its angle make light.Its profile can be adjusted according to on-the-spot needs.
Claims (3)
