Abstract

The utility model discloses a mine hoist depth indicator, which belongs to mine depth displaying devices. The mine hoist depth indicator comprises a box body, a right polish rod, a left polish rod, top covers, an indicating scale, travel switches, a worm gear, a worm, a driving lead screw, a driven lead screw, a driving gear, a driven gear and a nut with pointers, wherein the right polish rod and the left polish rod are fixed onto the box body; the top covers are fixed onto the right polish rod and the left polish rod; the indicating scale is fixed onto the right polish rod; the travel switches are respectively fixed onto the two polish rods; the worm gear and the worm are arranged inside the box body; one end of the driving lead screw is fixedly connected with the worm gear; the other end of the driving lead screw is installed on the top covers; the driven lead screw is installed between the top covers and the box body; and the driving gear and the driven gear are respectively arranged on the two lead screws. The worm (13) is driven by a motor (14) fixed onto the box body (11), and a sensor (1) fixed onto each top cover (3) is connected with the driven lead screw (16) through a coupler (2). The mine hoist depth indicator has the advantages of no limitation, small vibration, low noise, visual display and the like, and is an ideal device for displaying the depth of a mine.

Description

The mine hoist depth indicator

Technical field: the utility model relates to a kind of depth indicator, relates in particular to a kind of mine degree of depth read out instrument.

Background technology: at present, the mine hoist depth indicator generally all is a mechanical structure, it by housing, be arranged on leading screw in this housing, be arranged on the feed screw nut that has pointer on this leading screw and constitute.Because the conventional depth indicating device all is to adopt leading screw by transmission device and drum spindle direct connections such as everything joint or chains usually, therefore vibration is big, noise is high; And when steel cable need be readjusted or change because of elongation, all driving chain must be dismantled; Moreover, different well depths need dispose the gear of different drive ratios, very trouble.In addition, indicate also intuitively inadequately, can only rely on pointer to indicate roughly.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of mine hoist depth indicator easy for installation, simple in structure.

To achieve these goals, the utility model by the following technical solutions: it comprises casing, be fixed on two right polished rods and left polished rod on this casing, be fixed on the top cover on described right polished rod and the left polished rod, be fixed on the cuing scale on the right polished rod, be separately fixed at the travel switch on above-mentioned two polished rods, be arranged on worm gear and worm screw in the described casing, one end is captiveed joint the other end and is installed in active leading screw on the described top cover with this worm gear, be installed in the driven leading screw between top cover and the casing, the nut that is separately positioned on driving gear and the driven gear on described two leading screws and has pointer; Worm screw is fixed with on the top cover by coupler and driven leading screw bonded assembly sensor by the motor-driven that is fixed on the casing.

On cuing scale, be fixed with digital display screen.

Compared with the prior art, the utility model is owing to adopted technique scheme, on the basis of conventional depth indicating device, increased motor by Frequency Converter Control, and the transmission devices such as chain that will be connected between drum spindle and the depth indicator have changed into by PLC, the electrical controller that elements such as sensor constitute, therefore not only thoroughly solved the not contour problem in center between main shaft of hoister and the depth indicator, but also reduced intermediate mechanical bonded assembly link, have simple in structure, installation and maintenance are convenient, the on-site installation position is unrestricted, operate steadily, noise is low, advantages such as intuitive display.
