Description
The technical field is as follows:
the utility model relates to a technical field of powdered ore shipment machine especially relates to a special adjusting device of first high automation of shipment machine.
Background art:
at present, the slag is ground into powder in the production process of a company to form dust. The dust can be used for manufacturing building materials such as cement. Generally, 2 transportation modes are adopted: shipping and automotive.
At present, the mineral powder ship loader at the inland wharf adopts a bulk mode of controlling a large rotating arm, a small rotating arm and a vertical conical hoisting motor. The vessel to be loaded is typically provided with 7-11 ports, each port having a diameter of 400 and 450mm and a pitch of between 2.6 and 3.5 meters. When a ship needing to be loaded is close to a wharf, an operator on the spot of the ship loader controls the large arm and the small arm of the mineral powder ship loader to enable the loading chute bulk loading head to be aligned with a material hole of the ship to be loaded. After alignment, an operator operates the steel wire rope of the bulk head winch to lower down until the bulk heads below the chute are all placed in the material port of the ship, and delivery is started.
In the delivery process, along with the gradual increase of the loading weight, the ship sinks due to the increase of the weight, because the chute bulk head is aligned and descended, the hoisting motor controlling the lifting of the bulk head is already embraced by the band-type brake, when the ship sinks, the original bulk head is in close contact with the material port of the ship to form a gap, and because a certain air pressure exists in the loading chute, mineral powder immediately emerges from the cabin through the gap, thereby polluting the environment. Because the gap is small, even on the spot, the monitoring and control place is only a distance away from the ship, so that the operator can hardly find the gap, and the operator can see the gap only when the gap is grayed, even if the winch height is adjusted at the moment, the time is too late.
However, the operator can only manually lower the steel wire rope of the chute hoist until the chute bulk heads are completely contacted again when the chute hoist sinks and emits ash. Since the ship sinks while loading, it is loaded for a large part in 3-4 hours. Therefore, the operator needs to adjust the height of the chute bulk head for many times, and the operator always keeps staring at the close contact state of the bulk head. On the other hand, because the ship is in a river, the ship tends to move left and right after meeting because the ship or the phoenix passing by the periphery pass by, and the ship also comprises the attack of strong wind and strong waves, the swift current cylinder and the ship material opening can not be in close contact with each other frequently, and operators can not estimate the change of the wind waves and often emit ash under the condition.

The utility model discloses the theory of operation in an embodiment as follows: the tension of three steel wire ropes pressed on the traction bulk head indirectly reflects whether the bulk head riding on a ship material port is tightly sealed with the bulk head. When wire rope tension is big, then can appear pressing the running roller and up lift by wire rope, it is installed angle sensor and must detect out the angular variation in the swing arm, angular variation when detecting surpasss certain limit (blind spot), then the converter work of system automatic start hoist engine, the wire rope of winding at the hoist engine is down transferred, tension reduces, the bulk head is got back to on the ship material mouth again, maintain tension balance, realized that the bulk head follows the target of ship because of the goods naturally sinks and naturally unreel the rope or realize by the storm the local automatic release wire rope of ship blow off the centering position purpose. When the stormy waves appear blowing back the ship from the distant place, the wire rope that originally releases is taken back, and wire rope tension has diminished this moment, then can appear the pressure running roller and toward sinking, and its angle change that sinks surpasss certain limit (blind spot), starts the converter once more, and the wire rope that twines at the hoist engine up rolls up, and tension increase until balanced, wire rope has certain tension, neither pine nor too tight.
The mechanical parts and sensors of the device mainly comprise three parts:
the number of the swing arms can be two, the swing arms are arranged at two ends of the pressure roller wheel, the top ends of the swing arms are provided with holes and used for installing output shafts of the pressure roller wheel, the lower ends of the swing arms are fixed on the base, the swing angle of the swing arms can be 0-180 degrees, and the actual application range can be 60-150 degrees.
A set of pressure roller wheel for pressing three steel wire ropes is additionally arranged between the winch winding drum, the left and right steel wire rope horizontal wheels and the middle steel wire rope vertical wheel, the pressure roller wheel can be a cylinder, two ends of the pressure roller wheel extend out of the middle shaft, and the middle shaft is supported by the swing arm and fastened by the nut. The swing arm is fixed on the base of the tension device, the press roller is evenly pressed on the three steel wire ropes,
the size of the pressure roller wheel can be 60mm in diameter, 400mm in length, and the output shafts at the two ends are 20mm long and 8mm in diameter.
The set of device electric control device and the sensor mainly comprise four parts:
(1) an angle sensor: a0-180 degree angle sensor is provided, the working voltage DC24V, and the output 4-20mA. is arranged on a swing arm. The output of the PLC is connected with a PLC analog input card.
(2) Frequency converter or servo drive: the steel wire rope hoist motor that is originally controlled by the MCC of motor control center changes into the converter drive of adjustable speed, and a converter is increased again to hoist motor: because the angle change is not big, because of the ship nature sinks after the loading and the wave impact in the river and the natural strong wind changes, easily cause loose loading head and ship material mouth under the swift current section of thick bamboo to loosen, can not closely contact, appear to emit the ash. Because the clearance is not big, and frequent change, originally with MCC direct power supply mode, its control accuracy of adjusting the length of wire rope is not enough, and frequent regulation also has very big influence to the motor, consequently need control motor rotational speed with the converter in order to satisfy its frequent adjustment and control wire rope lifting accuracy two aspects requirement. If the frequency converter is used, the adjustment precision is not enough, so that the servo driver can be used for driving, and once the servo driver is used, a servo motor needs to be matched.
(3) A PLC device: if the original controller is provided with a PLC device, only a current 4-20mA analog quantity board card is added or one channel of the analog quantity of the original system is utilized. And inputting the output value of the angle sensor into the board card.
