First aspect of the utility model
Example 1
As shown in fig. 1 to 3, and in particular with reference to fig. 1, the present invention relates to a positioning system for a discharge carriage of a coal conveying mechanism 100, comprising:
the track 200 is provided with an identification mark 201, and the position of the identification mark 201 on the track 200 is right below the discharge hole 12 of the coal conveying mechanism;
a discharging trolley 300, on which a carrying shell 301 corresponding to the size of the identification mark 201 is mounted, a sensing device 302 (shown in fig. 2 to 3) mounted below the discharging trolley 300 for identifying the identification mark 201, and a roller 303 enabling the discharging trolley 300 to run on the track 200, wherein when the sensing device 302 identifies that the parameter index of the discharging trolley 300 running to the overlapped part of the carrying shell 301 and the identification mark 201 corresponds to the parameter index of the identification mark 201, the sensing device 302 sends a stop instruction to the discharging trolley 300, so that the discharging trolley 300 stops right below the discharging port 12; and
the camera 400 is installed at the upper part of the discharge port 12 and is used for taking a picture of the discharging trolley 300 stopped under the discharge port 12 and feeding the taken picture back to a background control system (not shown in the figure);
after the background control system acquires the shot picture, the relative position of the identification mark 201 and the bearing shell 301 of the discharge trolley 300 in the picture is compared, and when the relative position of the identification mark 201 and the bearing shell 301 of the discharge trolley 300 is deviated, an alarm is given.
Specifically, the rail 200 may be a single-row rail, a double-row rail or a multi-row rail, and the roller 303 is provided with a locking groove 304 on an outer wall along a circumference thereof, and a width of the locking groove 304 corresponds to a width of the rail 200, so that the dump truck 300 can be placed on the rail 200 through the locking groove 304 and travel along the rail 200. The number of rollers 303 may be arbitrarily selected according to the size of the tripper car 300 and the type of rail 200, and is disposed below the tripper car 300 in a symmetrical manner.
In a preferred embodiment of the utility model, the rails 200 are double-row rails, the number of rollers 303 is 4, and they are arranged in an angularly symmetrical manner below the tripper car 300.
The identification mark 201 may be disposed on either side of the rail 200 in the extending direction of the rail 200, preferably, on the upper portion of the rail 200. The length of the carrying case 301 of the dump truck 300 in the extension direction of the rail 200 corresponds to the length of the identification mark 201 provided on the rail 200, preferably the length of the identification mark 201 ranges between 1.5m-3 m.
In a preferred embodiment of the utility model, the length of the identification mark 201 and the carrier housing 301 in the extension direction of the rail 200 is 2.7 m.
More specifically, the identification mark 201 on the track 200 may be understood as the emitting end of a signal for driving the discharge trolley 300 to stop at a desired position to receive the material discharged from the discharge port of the coal conveying mechanism.
Specifically, the identification mark 201 may emit any one of a laser sensing signal, an infrared sensing signal, a pressure sensing signal, and an image sensing signal. Correspondingly, the sensing device 302 is used for receiving the signal emitted by the identification mark 201. It should be understood that when the identification mark 201 is a laser sensing device, the sensing device 302 is correspondingly a laser sensing device; when the identification mark 201 emits an infrared sensing signal, the sensing device 302 is correspondingly an infrared sensing device; when the identification mark 201 emits a pressure sensing signal, the sensing device 302 is correspondingly a pressure sensing device; when the identification mark 201 emits a laser sensing signal, the sensing device 302 is correspondingly an image recognition sensing device.
For example, when the identification mark 201 emits a laser sensing signal, laser light is emitted at both ends of the identification mark 201. When the discharging car 300 travels along the track 200 toward the identification mark 201, the sensing device 302 is always in a state of receiving the laser emitted from the two ends of the identification mark 201. Specifically, the sensing device 302 is always in the position to identify whether the discharge cart 300 completely blocks the laser emitted from the two ends of the identification mark 201. In other words, when the sensing device 302 recognizes that the discharge car 300 completely blocks the laser emitted from the two ends of the identification mark 201, the sensing device 302 determines that the discharge car 300 has moved until the length dimension of the overlapped portion of the carrying housing 301 and the identification mark 201 corresponds to the length dimension of the identification mark 201, and then the sensing device 302 issues a stop command. On the contrary, the sensing device 302 determines that the length of the overlapped portion of the carrying housing 301 and the identification mark 201 is smaller than the length of the identification mark, and the sensing device 302 does not issue the stop command.
For example, when the identification mark 201 emits an infrared sensing signal, the working principle thereof is substantially the same as that of the identification mark emitting a laser response signal, and the difference is only that infrared light is emitted from both ends of the identification mark 201 at this time, and the same parts are not described herein again.
For example, when the identification mark 201 emits an image sensing signal, the working principle of the identification mark is substantially the same as that of the identification mark emitting a laser response signal, except that the sensing device 302 determines whether all the image signals emitted from the identification mark 201 are completely received, and the description of the same parts is omitted here.
For example, when the identification mark 201 is a pressure sensing signal, the sensing device 302 determines whether the weight of the discharge trolley 300 running until the overlapped part of the loading housing 301 and the identification mark 201 reaches the threshold set by the identification mark 201. Specifically, when the sensing device 302 recognizes that the dump truck 300 runs until the weight of the overlapped part of the bearing shell 301 and the identification mark 201 reaches the threshold value set by the identification mark 201, the sensing device 302 sends a stop command. On the contrary, the sensing device 302 determines that the weight of the overlapped portion of the carrying device 301 and the identification mark 201 is smaller than the threshold value of the identification mark, and the sensing device 302 does not issue the stop instruction.
According to an embodiment of the present invention, the number of the identification marks 201 corresponds to the number of the discharge ports 12.
The explanation of the technical term "parameter index of overlapping portion" in the present invention is as follows: as shown in fig. 2, the parameter index a of the overlapped portion indicates that the sensing device 302 of the dump truck 300 has not completely sensed all the sensing signals sent by the identification mark 201, and at this time, it is determined that the dump truck 300 has not driven into the designated location; as shown in fig. 3, the parameter index a' of the overlapped portion indicates that the sensing device 302 of the dump truck 300 has completely sensed all the sensing signals sent by the identification mark 201, and at this time, it is determined that the dump truck 300 has driven into the designated location.
Example 2
Embodiment 2 of the first aspect of the present invention is substantially the same as embodiment 1 described above, except that a fixed point determination method is used between the sensing device 302 and the identification mark 201. Compared with the first aspect, the same parts are not described herein in detail, and the details of the different parts are as follows:
as shown in fig. 4, in the embodiment 2, the identification mark 201 is a signal emitting point disposed on the track 200, when the dump truck 300 travels to the identification mark 201, the sensing device 302 senses the signal emitted from the point, and when the sensing device 302 receives the signal emitted from the identification mark 201, the sensing device 302 emits a stop command. Otherwise, the sensing device 302 does not issue the stop command.
Similar to embodiment 1, the identification mark 201 may emit any one of a laser sensing signal, an infrared sensing signal, a pressure sensing signal and an image sensing signal.
Second aspect of the utility model
A second aspect of the utility model relates to a coal conveying mechanism 100, said coal conveying mechanism 100 comprising a tripper trolley positioning system as described in the first aspect.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
