Description
Technical field
The utility model relates to a kind of online detection instrument, specifically is a kind of sinking shaft suspension wire rope on-line measuring device.Mainly be applicable to the online detection of suspention preparation of construction wire rope in the shaft of vertical well pick block.
Background technology
In [underground, particularly the pick of shaft of vertical well is built, and all preparation of construction are all suspended in midair by wire rope.The safety coefficient of wire rope is directly connected to the construction safety of mine, and especially Suspenoing apparatus is subjected to impact force action or is blocked phenomenon, and its instantaneous value will be multiplied, and it is just very necessary therefore to detect the wire rope force-bearing situation.But do not have special checkout equipment so far.
Summary of the invention
The utility model provides a kind of sinking shaft suspension wire rope on-line measuring device, can realize online detection, the monitoring of suspention preparation of construction wire rope in the shaft of vertical well pick block.
The utility model is realized with following technical scheme: a kind of sinking shaft suspension wire rope on-line measuring device comprises:
Be installed in a plurality of force cells of gathering each steel wire rope tension value on hanging scaffold or the suspention template platform;
Be connected the A/D change-over circuit that the tension value analog signal conversion is become digital signal with each force cell;
The upper single-chip microcomputer that is connected with the A/D change-over circuit;
The radiating circuit that is connected with upper single-chip microcomputer;
Be installed in ground receiving circuit;
The next single-chip microcomputer that is connected with receiving circuit through the RS232 interface;
The digital display, printing, warning and the executive circuit that are connected with the next single-chip microcomputer.
Each force cell converts the tension value (simulating signal) of each wire rope to digital signal by the A/D change-over circuit, sends in the radiating circuit that is installed on the hanging scaffold after handling through upper single-chip microcomputer again, and radiating circuit passes the signal to ground.Signal is delivered to the next single-chip microcomputer through receiving circuit and is handled accordingly, by digital display, printing, warning and executive circuit output.
The beneficial effects of the utility model are: system's antijamming capability is strong, degree of accuracy is high, easy to operate, defencive function is complete, guarantees the stressed real-time detection of suspension wire rope.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
