Description
Technical field
The present invention relates to the one protective device that falls to restrict, all fronts that the steel wire rope that especially can realize high speed impractical person vehicle falls rope form state are detected and the high speed impractical person vehicle of early warning parking falls to restrict protective device.
Background technology
The shortcomings such as at present, the conventional protective device that falls to restrict just detects at device key position, detects completely if realize steel wire rope, must rope sensor be installed one by one in holder rope sheave position, and project investment funds are high, fault rate is high and maintenance workload is large.
Summary of the invention
In order to overcome the shortcoming such as installation trouble, fault rate height of traditional protective device that falls to restrict; the invention provides a kind of high speed impractical person vehicle protective device that falls to restrict; this protective device that falls to restrict only need be arranged on high speed impractical person vehicle head place and can fall all fronts steel wire rope the detection of rope form state, realizes early warning and stops.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high speed impractical person vehicle protective device that falls to restrict; there is signal leading device and checkout gear; it is characterized in that: signal leading device is made up of the conductive casters being fixed on rack beam; conductive casters is connected with the output signal positive pole of checkout gear; rack beam is connected with the output signal negative pole of checkout gear; in the housing of checkout gear; intrinsic safety electric source is powered to circuit board, has signal protection circuit, testing circuit and single-chip microcomputer treatment circuit fall to restrict on circuit board.
Checkout gear is made up of housing, intrinsic safety electric source, circuit board, loudspeaker, indicator lamp.
Conductive casters is roller type, is fixed on rack beam and with frame and insulate, and conductive casters is divided into upper and lower two-wheeled, and upper conductive casters is adjustable according to tightness of steel wire rope degree.
Signal protection circuit output end has the combination absorbing circuits such as TVS pipe, piezo-resistance, ceramic discharge tube, can absorb extraneous surge electrostatic potential, the safety of protection internal circuit.
Signal leading device and steel wire rope Elastic Contact, signal protection circuit detects steel wire rope signal by signal leading device.
When the testing circuit that falls to restrict detects rope fault; pretreatment through signal protection circuit is exported fault-signal to single-chip microcomputer treatment circuit; by single-chip microcomputer treatment circuit analyzing and processing; by loudspeaker output alarm; and have indicator lamp flash for prompting, send signal to extraneous electric-control system simultaneously and realize early warning and stop.
The invention has the beneficial effects as follows, can fall to steel wire rope all fronts detection of rope form state, reduce workload, reduce cost.
