Description
Technical Field
The utility model relates to a colliery hillock parking field, concretely relates to dual accurate parking equipment of hillock.
Background
Along with the continuous lifting of raw coal, the lifting task of a gangue system is heavier and heavier. The gangue system is lifted in a mountain top mode, the mine car is pulled through the winch to convey the gangue to the mountain top, in the existing parking system, the parking sensor is arranged at the end of the track, when the mine car unloads the gangue, the sensor is easily damaged, and therefore the situation that the mine car cannot be parked occurs; moreover, due to the fact that the tail end of the track is suspended, once the sensor is damaged, a large potential safety hazard exists when personnel maintain the sensor. Therefore, the existing gangue dump parking system cannot meet the actual production requirement.
SUMMERY OF THE UTILITY MODEL
Potential safety hazard to existence among the current hillock parking system, the utility model provides a dual accurate parking equipment of hillock.
The utility model adopts the following technical proposal:
the utility model provides a dual accurate parking equipment of hillock is provided with the track on the hillock, is connected with the mine car on the track, and the mine car passes through the winch pulling and moves on the track, and the device includes sensor parking structure, encoder parking structure and control box, sensor parking structure includes the sensor, and the sensor setting is on the track, and the position of sensor is apart from the track end at least 3.5 meters, the sensor includes two tongue tube sensors, sets up around two tongue tube sensors and sets up
The encoder parking structure comprises a parking encoder, the parking encoder is connected with the winch, and the parking encoder can record the moving distance of the mine car;
a change-over switch, a relay and a PLC system are arranged in the control box, the two reed switch sensors are electrically connected with the change-over switch, the change-over switch is electrically connected with the relay, and the relay is electrically connected with the PLC system; the parking encoder is electrically connected with the PLC system.
Preferably, one of the two reed switch sensors is a main sensor, the other one of the two reed switch sensors is an auxiliary sensor, and one reed switch sensor is selected to be connected with the relay through the change-over switch.
The utility model has the advantages that:
the utility model provides a dual accurate parking equipment of hillock through sensor parking structure and encoder parking structure dual accurate parking, when the sensor parking structure breaks down, can have the parking encoder to realize parkking, ensures that the mine car parks accurately, can not appear the accident that can't park; the position of the sensor is arranged at the rear of the end of the track, so that the sensor is not buried or crushed by unloaded gangue, and the sensor is convenient for workers to maintain. The utility model discloses simple structure, the operation of parkking to the hillock mine car that can be fine accords with current production demand.
Drawings
Fig. 1 is a schematic structural diagram of a dual precise parking device for a hillock.
Detailed Description
The utility model is described in detail with the following figures:
referring to the figure 1, the dual accurate parking device for the waste rock hill is characterized in that a track 2 is arranged on the waste rock hill 1, a mine car 3 is connected to the track, and the mine car moves on the track by being pulled by a winch
The device also comprises a sensor parking structure, an encoder parking structure and a control box.
The sensor parking structure comprises a sensor, wherein the sensor is arranged on the track, and the position of the sensor is at least 3.5 meters away from the end of the track.
Compare in current sensor setting at the track end, this device moves the sensor backward, can guarantee like this that the sensor can not buried or crush by the waste rock of uninstallation, moreover, makes things convenient for the staff to maintain the sensor.
The sensor comprises two reed switch sensors which are arranged in the front and back. One of the two reed switch sensors is a main sensor 4, and the other is an auxiliary sensor 5.
The encoder parking structure comprises a parking encoder, the parking encoder is connected with the winch, and the parking encoder can record the moving distance of the mine car.
A change-over switch, a relay and a PLC system are arranged in the control box.
The two reed switch sensors are electrically connected with the change-over switch, the change-over switch is electrically connected with the relay, and the relay is electrically connected with the PLC system.
A reed switch sensor is selected to be connected with the relay through the change-over switch, the main sensor works normally, and once the main sensor is damaged, the change-over switch enables the auxiliary sensor to be connected into the relay.
The parking encoder is electrically connected with the PLC system.
Example 1
Take the example where the sensor is 3.5 meters from the end of the track and the distance from the encoder to the end of the track is 67 meters.
The working principle of the device is roughly as follows:
when the winch pulls the mine car to lift, the PLC system obtains the moving distance of the mine car recorded by the parking encoder in real time, when the mine car moves to the position of the sensor, the sensor sends a signal to the PLC system through a relay, when the mine car continues to move forward for 3.5 meters, the PLC control system controls the braking system of the winch to brake, the mine car stops moving forward, and at the moment, gangue on the mine car is dumped;
when two reed switch sensors all break down, the mine car is lifted to the sensor position, the PLC system does not receive signals fed back by the sensors, the mine car is stopped through the parking encoder at the moment, when the parking encoder records that the mine car moves 67 meters, the PLC control system controls the winch braking system to brake, and the mine car stops moving forwards.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
