Row control module after described treater comprises load module, logic sum gate module, logical AND gate module, chain move ahead control module and chain, the input end of load module is connected with the mouth of proximity switch, the input end of logic sum gate module is connected with the mouth of load module, the input end of logical AND gate module is connected with the mouth of logic sum gate module, and the mouth of the logical AND gate module control module that moves ahead with chain is respectively connected with row control module after chain.
Described detection rope is steel rope, and baffle plate is metal induction baffle plate, and proximity switch is magnetic inductive proximity switch.
On the other hand, a kind of stand chain breakage method of inspection, comprises the following steps:
A. below stand chain, lateral arrangement one detects rope, and perpendicular with chain;
B. connect a baffle plate by after one end pile warp fixed pulley of detection rope, make to detect this end of rope and naturally droop;
C. proximity switch is set in baffle plate side, in order to detect baffle plate activity;
D. when falling behind under chain breakage, pressing down and detecting rope, baffle plate by detect rope band dynamic on move, after proximity switch detects, output detection signal is to treater, sends control signal and alerting signal by treater.
In step D, the detection signal sent by proximity switch is received by the load module of treater, and input logic or door module and logical AND gate module carry out signal transacting successively, and output control signals to chain and to move ahead row control module after control module and chain, carry out corresponding chain control.
In technique scheme, stand chain breakage detecting device of the present invention and method, rope is detected by lateral arrangement one below stand chain, when chain breakage, drop on detection rope under meeting go up and press down detection rope, detection rope band is moved on baffle plate move, and detected by proximity switch, then receive detection signal by treater and send corresponding control signal and alerting signal.Adopt this detecting device and method, can detect stand chain in real time, be conducive to Timeliness coverage chain breakage, not only can avoid having an accident, but also substantially reduce the repair time.
Accompanying drawing explanation

Fig. 2 is the schematic side view of stand chain breakage detecting device of the present invention;
Fig. 3 is the functional block diagram of treater of the present invention.
Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with drawings and Examples.
Refer to Fig. 1, shown in 2, stand chain breakage detecting device of the present invention mainly comprises a detection rope 1, fixed pulley 2, baffle plate 3, proximity switch 4 and treater 5, this detection rope 1 can adopt steel rope, one end lateral arrangement is perpendicular and fix below stand chain 6 and with chain 6, other end pile warp fixed pulley 2 is rear and sagging, baffle plate 3 can adopt metal to respond to baffle plate 3, and be located at the low end detecting rope 1, as inductor and counterweight, proximity switch 4 can adopt magnetic inductive proximity switch 4, be located at baffle plate 3 side, movable in order to detect baffle plate 3, the mouth of proximity switch 4 is electrically connected with treater 5, in order to transmit detection signal.
Please gather shown in Fig. 3, row control module after described treater 5 comprises load module, logic sum gate module, logical AND gate module, chain move ahead control module and chain, the input end of load module is connected with the mouth of proximity switch 4, the input end of logic sum gate module is connected with the mouth of load module, the input end of logical AND gate module is connected with the mouth of logic sum gate module, and the mouth of the logical AND gate module control module that moves ahead with chain is respectively connected with row control module after chain.
The method of inspection of above-mentioned stand chain breakage detecting device, comprises the following steps:
A. below stand chain 6, lateral arrangement one detects rope 1, and perpendicular with chain 6;
B. connect a baffle plate 3 by rear for one end pile warp fixed pulley 2 detecting rope 1, make to detect this end of rope 1 and naturally droop;
