Abstract
The utility model discloses a digital depth indicator control system of a mine hoist, which belongs to mine depth displaying devices and aims to provide a control system with visual display, convenient installation and simple structure of a mine hoist mine depth displaying device. The control system comprises a depth indicator provided with a digital display board (11); the depth indicator (10) is driven by a servo motor (8) electrically connected with a PLC (3) through a frequency converter (1); a main shaft encoder (2) and an indicator encoder (4) are respectively arranged on a main shaft and the depth indicator (10) and electrically connected with the PLC; and a motor encoder (9) electrically connected with the frequency converter (1) is arranged on the servo motor (8). The control system has the advantages of no limitation, small vibration, low noise, visual depth display and the like, and is an ideal control device of the mine hoist mine depth displaying device.
Description
Technical field: the utility model relates to a kind of control system, relates in particular to a kind of mine hoist that shows and promotes the digitalisation indicator control system of the degree of depth.
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 display control unit of conventional depth indicating device all is to adopt leading screw by transmission device and drum spindle direct connection modes 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, degree of depth indication is also directly perceived 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 intuitive display, mine hoist digitalisation depth indicator control system easy for installation, simple in structure.
To achieve these goals, the utility model by the following technical solutions: it comprises depth indicator; The depth indicator that is provided with the digital display board is by driven by servomotor, this servomotor is electrically connected with PLC by frequency converter, on main shaft and depth indicator, be respectively equipped with the spindle encoder and the indicating device coder that are electrically connected with this PLC, on servomotor, be provided with the motor encoder that is electrically connected with frequency converter.
On depth indicator, be provided with the pulleying travel switch, retarding travel switch and the two stage braking that are electrically connected with PLC respectively and remove travel switch.
Compared with the prior art, the utility model is owing to adopted technique scheme, on the basis of traditional mechanical formula depth indicator, increased servomotor 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 coder constitute, therefore not only thoroughly solved the not contour problem in center between drum spindle 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 degree of depth intuitive display.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: frequency converter 1 spindle encoder 2 PLC3 indicating device coders 4 two stage brakings are removed travel switch 5 retarding travel switches 6 pulleying travel switches 7 servomotors 8 motor encoders 9 depth indicators 10 digital display boards 11
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: depth indicator 10 is provided with digital display board 11, and the leading screw that is located in this depth indicator is driven by servomotor 8, and this servomotor is by frequency converter 1 control that is electrically connected with PLC3; The indicating device coder 4 that is located at the spindle encoder 2 on the main shaft and is located on the depth indicator 10 is electrically connected with PLC3 respectively, and the motor encoder 9 that is located on the servomotor 8 is electrically connected with frequency converter 1.In order to improve safety, on depth indicator 10, be provided with pulleying travel switch 7, retarding travel switch 6 and two stage braking and remove travel switch 5, above-mentioned three travel switches are electrically connected with PLC3 respectively.
