Automatic trough-unloading truck with remote controller

Abstract

The automatic trough-unloading truck with remote controller for metallurgical industry has on-truck electric equipment connected to and controlled by on-truck control box and driven with the on-truck electric driving equipment; on-truck control box with communication lines and power lines connected to the collecting box; collecting box with communication lines and power lines connected via power-communication cable to ground connecting box; and ground connecting box with communication lines connected to central controller via communication cable and power lines connected to ground power distributor via power cable. The trough-unloading truck is controlled with the ground central controller to complete various detection, control and execution operations.

Description

technical field [0001] The invention relates to a mobile unloading vehicle for a storage trough in the metallurgical industry, in particular to an automatic unloading vehicle for a trough, which can be widely used in metallurgy, coal, cement, grain, storage and transportation and other industries. Background technique [0002] The trough mobile automatic unloading vehicle includes many electrical devices, such as running parts, cable coiling parts, electric chute parts, detectors, walking alarms, material level detectors, other equipment and grounding parts, the connection of these parts , control and drive are carried out through the cable. see figure 2 , the various equipment status signals detected by the detection device on the existing unloading car are connected to dozens of the current collector boxes of the cable winding parts through the respective connected control cables (the specific number depends on the number of devices on the unloading car) ) The current co...

AI Technical Summary

Problems solved by technology

[0003] The existing trough automatic unloading vehicle has the following defects: 1. A large number of signals and mechanical drive control connections of the unloading vehicle are completed by coiling cables through current collector slip rings, and the number of cable core wires and current collector slip rings depends on The number of signals and actuators required by the unloading truck generally has at least dozens of core wires and dozens of slip rings

2. The power and control coiling cable used has many cores, complex structure, high price and high cable damage rate

3. There are a large number of collector slip rings, and they are sliding contacts. This structure and form determine frequent failures

4. Difficulty in debugging

There are a large number of electrical devices on the hopper unloading vehicle, and the control of these electrical devices is scattered in various places on the ground, which brings great difficulties to debugging

5. The slot position control is complex

In the prior art, a limit switch is installed in every groove on the ground, and it is used to indicate the groove position and control the parking point. How many such limit switches will be installed as many grooves as there are, and the faults caused by the limit switches are also There are too many, affecting the normal operation of the production system

6. The signal transmission distance of the existing technology is long, and all functions must be controlled by the calculation of the central control main PLC, and the real-time control is poor

7. The fixing device of the single-action operation box on the machine side of the prior art is on the ground, and the travel distance of the unloading truck varies from tens of meters to more than a hundred meters depending on the number of slots. In actual operation, it is neither convenient nor safe
