Abstract
The utility model discloses an automatic control winch overwinding protector for mines, which has low fault rate, safety and durability, does not restrained by application range, and can reduce maintenance cost. The technical scheme is that a cable (6) is connected with a winch control switch (7), a PLC control box (8) and a voice alarm (9), and an A rail sensor (3), a B rail sensor (4) and a C rail sensor (5) are connected on the PLC control box (8) in turn. The utility model is mainly used on the winch overwinding prevention under coal mine wells.
Description
Technical field
The utility model relates to a kind of mining automatic guidance winch overwinding safety gears.
Background technology
Under coal mine in each inclined gallery belt heading, a winch all is installed for the usefulness that promotes transporting material, for preventing the winch pulleying, mostly adopt the controller of analogous circuit and Design of Digital Circuit to control, what the sensor in the controller was used is rotary encoder and limit switch, it also can only be installed on several large-scale winch of depth indicator, and can not be suitable for the gypsy winch that does not have depth indicator, this kind control structure fault rate height, maintenance capacity is big, difficulty is installed, and Applicable scope is limited.
Summary of the invention
The technical matters that the utility model solves is: a kind of mining automatic guidance winch overwinding safety gears are provided, and its fault rate lower security is durable, reduces maintenance cost, and easy for installation, Applicable scope is unrestricted.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: cable connection winch master cock, PLC control box and phonetic alarm, A rail sensor, B rail sensor and C rail sensor connect the PLC control box in order successively.
Because adopt technique scheme, the utility model fault rate is low, safety durable can reduce maintenance cost, applied widely can being installed on the big gypsy winch easy for installation.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure:
Winch 1, mine car 2, A rail sensor 3, B rail sensor 4, C rail sensor 5, cable 6, winch master cock 7, PLC control box 8, phonetic alarm 9.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Shown in the accompanying drawing: cable 6 connects winch master cock 7, PLC control box 8 and phonetic alarm 9, and A rail sensor 3B rail sensor 4 and C rail sensor 5 connect PLC control box 8 in order successively.What three sensors 3,4,5 adopted is the hermetically sealed non-contact type mine car of prior art counting machine.
Use the utility model, three sensors 3,4,5 be installed in successively rail under, when mine car 2 was crossed A rail sensor 3, winch 1 was understood and be stopped operating under the control of PLC control box 8, thereby has prevented the equipment damage that winch 1 pulleying brings.
Claims (1)
