Detailed description of the invention
A kind of oil quenching bath chain movement state monitoring apparatus, as shown in Figure 1, comprising: detect main support 1, regulating plate 2, check-out console 3, rotary axle box 5, turning cylinder 6, bearing 7, spacer pad 8, chain contact plate 9, testing stand 11, strut bar 12, proximity switch 13, sleeve 14, screw 15, roller 18, chain 19, dinosaur frame 20 etc.Wherein:
Main support 1 is fixed by the mode of welding with dinosaur frame 20 side, main support 1 is provided with regulating plate 2, described regulating plate 2 offers two elongated slots, is fixed on main support 1 with the screw of four M8 through elongated slot by regulating plate 2; Regulating plate 2 has positioning groove, and rotary axle box 5 is weldingly fixed on regulating plate by positioning groove; In rotary axle box 5, being provided with turning cylinder 6, between turning cylinder 6 and rotary axle box 5 two ends, being provided with needle bearing 7, in order to prevent vibration, being respectively arranged with step cutting pattern at the two ends of turning cylinder 6 and spacer pad 8 positions.Two head ends of turning cylinder 6 are fixed with check-out console 3 and chain contact plate 9 respectively.Main support 1 is fixed with strut bar 12, strut bar 12 is provided with regulating sleeve 14, regulating sleeve 14 is welded with testing stand 11, testing stand 11 is provided with proximity switch 13.
The effect of two elongated slots that regulating plate 2 is offered is the positions that conveniently can arrange regulating plate 2, to guarantee to be fixed on the center that the chain contact plate 9 fixed turning cylinder 6 one end in the rotary axle box 5 on regulating plate can be in the roller 18 of chain 19.
The control circui of this device as shown in Figure 5, comprise: battery isolator control 1AT, very first time relay K T1, the second time relay KT2, Switching Power Supply, relay K 1, relay K 2, bi-colour light annunciator (band red light and green light), proximity switch J1 (i.e. proximity switch 13), wherein: (from left to right, telling about from top to bottom) time relay KT1, KT2 all access 220V alternating current.One end of the normally closed contact of relay K 1 is connected with the reset terminal 6 of KT1, and the other end and OV hold 5 to be connected, and one end of its open contact is connected with the reset terminal 8 of KT2, and the other end and OV hold 7 to be connected.Proximity switch J1 accesses the 24V direct current (DC) of Switching Power Supply, and its signal end 9 is connected with the coil negative terminal of relay K 1, and the anode of relay K 1 is connected with the positive supply 3 of 24V, forms a closed loop.An often ported termination 24V positive supply of time relay KT1, KT2, the other end is then connected with one end of the coil of relay K 2, annunciator and alarm lamp RD, and node is 10; The other end access 24V negative supply 4 of the coil of relay K 2, annunciator and alarm lamp RD, forms a closed loop.The normally closed contact one termination 24V positive supply 3 of relay K 2, the other end is connected with run indicator GN, and the other end of run indicator GN is connected with 24V negative supply 4, forms a closed loop.Another group normally closed contact of relay K 2 is then connected (such as compression machine or equipment related with oil sump) with the power circuit (14,15) of external device.
Principle of work of the present utility model is: when chain 19 is under driven by motor, during by the direction motion indicated, chain contact plate 9 alternately swings up and down in the gap between roller 18 and roller, check-out console 3 also swings up and down thereupon, ceaselessly pass through and leave proximity switch 13, thus proximity switch 13 is constantly obtained and loss signal.In operational process, when proximity switch 13 (i.e. J1) obtains signal, the coil energized action of relay K 1, its normally closed contact connected with KT1 disconnects, and the very first time, relay K T1 started timing; The open contact connected with KT2 closes, and the second time relay KT2 just resets, no longer timing.When proximity switch 13 (i.e. J1) loss signal, relay K 1 no longer electric, its contact be connected with KT1, KT2 restPoses, and so, the second time relay KT2 starts timing, and simultaneously very first time relay K T1 resets, no longer timing.In the process (when namely normally running), relay K 2 not electric, contact also can not action, so run indicator GN obtains electric (bright green).(illustrate that check-out console is not swinging up and down normally when any one time relay (KT1 or KT2) reaches the upper limit time value of setting, namely chain contact plate 9 does not normally swing up and down, illustrate that chain card rises normally not run), the closing of contact of KT1 or KT2, alarm lamp RD obtains electric (sending out a warning), alarm equipment alarm.Simultaneously, relay K 2 coil obtains electric, its normally closed contact disconnects, run indicator GN dead electricity, green light extinguishes, and has cut off (14,15) that are connected with external equipment main power source simultaneously, has cut off the main power source of external equipment and relevant device, prevent the heat material processed from continuing to enter oil sump, avoid the generation of fire.
