Technical field
The utility model relates to a kind of opencast mining plant equipment, relates in particular to the position height pick-up unit between a kind of dumping plough discharge arm casting end and material.
Background technology
Current, in the middle of the winning apparatus of ore deposit, stockpile refers to solid material in the open, the similar conical stockpile forming in refuse dump from the free-falling of dumping plough discharge arm.The detection of dumping plough discharge arm discharge pit material stack height, is used zero distance pick-up unit often to run into a lot of problems puzzlements, as complex structure, precision are not high, humidity of materials temperature etc.Make material level signal alarm inaccurate, affect production efficiency.
Utility model content
For above-mentioned prior art, the utility model provides a kind of pick-up unit of dumping plough material stack height, can accurately detect in real time the height of discharge heap, have simple in structure, the feature such as reliability is strong, and cost is lower, easy to install.
In order to solve the problems of the technologies described above, the pick-up unit of a kind of dumping plough material stack height of the utility model, comprise detection case, in described detection case, be provided with multiple laser displacement sensors, the both sides of described detection case are provided with linkage component, every cover linkage component comprises minor axis and connecting rod, one end of described minor axis is provided with ring flange, one end of described connecting rod is provided with sleeve, this jacket casing is on described minor axis, the other end of described minor axis is provided with hubcap, described hubcap is fixed by screw, the other end and the detection case of described connecting rod are fixed, this pick-up unit also comprises PLC Programmable Logic Controller.
The pick-up unit of the utility model dumping plough material stack height, wherein, described sleeve and described minor axis are slidably matched; Multiple laser displacement sensors are distributed on the top in described detection case.
Compared with prior art, the beneficial effects of the utility model are:
In the utility model, be provided with multiple laser displacement sensors, can realize non-contact measurement, reduce the wearing and tearing of measurement mechanism, avoid bumping with material, improved safe reliability, and there is very strong practicality.
Accompanying drawing explanation
Fig. 1 is the front view of the pick-up unit of the utility model dumping plough material stack height;
Fig. 2 is the A-A view of pick-up unit shown in Fig. 1.
In figure: the driven cylinder of 1-, the driven drum supporting device of 2-, 3-minor axis, 4-connecting rod, 5-hubcap, 6-screw, 7-protective device, 8-displacement transducer.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
As shown in Figure 1, the pick-up unit of a kind of dumping plough material stack height of the utility model, comprise detection case 7, in described detection case 7, be provided with multiple laser displacement sensors 8, on the uniform end face being firmly arranged in detection of multiple laser displacement sensors 8, the both sides of described detection case are provided with linkage component, every cover linkage component comprises minor axis 3 and connecting rod 4, one end of described minor axis 3 is provided with ring flange, one end of described connecting rod 4 is provided with sleeve, this jacket casing is on described minor axis 3, described sleeve and described minor axis 3 are slidably matched, the other end of described minor axis 3 is provided with hubcap 5, hubcap 5 centers are with circular hole, be fixed on minor axis 3 by this circular hole with screw 6, this hubcap 5 can prevent that connecting rod 4 from detaching minor axis 3, the other end of described connecting rod 4 and detection case 7 are fixing, detection case 7 can be a square box, therein through being processed with square or other shapes for protecting and install multiple laser displacement sensors 8, this pick-up unit also comprises PLC Programmable Logic Controller.
While using the utility model, the ring flange inner side that is positioned at minor axis 3 one end in two cover links is welded on the driven drum supporting device 2 of discharge arm, due to connecting rod 4 upper ends be by jacket casing on minor axis 3 and be slidably matched, connecting rod 4 can be rotated around minor axis 3, object is to make the direction of pick-up unit not be subject to the variation of discharge arm luffing angle and change, under Action of Gravity Field always in plumbness.The lower end of connecting rod 4 can be connected to bolt the top of detection case 7, as shown in Figure 2, also can adopt and be welded and fixed.In the time of discharge arm swing certain angle, detection case 7 can prevent laser displacement sensor 8 and the collision of stockpile top wherein, and on discharge arm, fallen material also can not be fallen on laser displacement sensor 8 simultaneously, plays a protective role.The concrete number of detection case 7 inner laser displacement transducers 8 can be adjusted according to discharge arm belt width (determining stockpile size).The signal detecting is sent to PLC Programmable Logic Controller by laser displacement sensor 8, in PLC, compare, PLC exports rapidly and accurately the minimum constructive height signal between discharge arm and stockpile to cab and carries out alarm indication, thereby send stockpile reach capacity height alerting signal, the utility model adopts PLC to control and man-machine switching technology, even if the inspection center of laser displacement sensor 8 is without crossing stockpile center, also can judge relatively accurately the position of discharge arm, set after the minimum constructive height ultimate value of discharge arm and stockpile, still can detect reliably the minimum constructive height between discharge arm and stockpile, in real time discharge arm is monitored and controlled.
The utility model pick-up unit not only can, for the bank height detection of dumping plough, can also be used for the detection of other material stack heights.
Although the utility model is described in conjunction with figure above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that not departing from the utility model aim, can also make a lot of distortion, within these all belong to protection of the present utility model.
