Description

Technical Field

[0001] The invention relates to the field of conveyors, and in particular to an automatic detection and control system for a tubular belt conveyor. Background Art

[0002] Belt conveyor is a kind of conveying equipment commonly used in industrial production. It has the advantages of fast transmission speed, high transmission efficiency and stable operation. Therefore, it has broad application prospects in industrial production. It is well known that with the strengthening of national environmental protection actions, logistics loss and overflow problems in many coal-fired power, steel, chemical, mining, building materials and other industries have become a headache for these companies. After upgrading the pipe belt conveyor to a pipe belt conveyor, it is widely used because of its simple structure, strong adaptability and stable operation.

[0003] Compared with traditional belt conveyors, tubular belt conveyors do not need to occupy a lot of space and human resources, which can save production costs.

[0004] Since only the unloading and feeding ends of the tubular belt conveyor are laid out flat, and the rest of the tubular structure is a tubular structure, the middle part is rolled up due to its long length, and the on-site supervisor cannot monitor both sides from beginning to end. If there is a problem at a certain position and it cannot be discovered in time, it will cause irreversible damage, which will inevitably bring direct economic losses to the production company. Therefore, it is very necessary to ensure that the tubular belt conveyor runs unmanned and in a stable state. Summary of the invention

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The present invention provides Figure 1-6The tubular belt conveyor automatic detection and control system shown in the figure comprises a conveyor belt 1 and a column foot 2. The conveyor belt 1 is installed overhead through the column foot 2. The conveyor belt 1 comprises a bending portion 11, a head end 12 and a tail end 13. The head end 12 is provided with a first mounting frame 113 and a conveying shell 115. The conveying shell 115 is installed on the first mounting frame 113. The tail end 13 is provided with a second mounting frame 114. A third mounting frame 116 is installed on one side of the conveying shell 115. The conveyor belt 115 also comprises a driving component 3, a control terminal 4, a cleaning component and a detection component. The driving component 3 is arranged on the conveyor belt 1. The driving component 3 adopts a frequency conversion technology to drive the conveyor belt 1 to move. The control terminal 4 is arranged at the head end 12 and the tail end 13. The control terminal 4 is composed of Siemens 1200CPU and industrial control machine. The 1200CPU receives, sends and logically controls the power and signal data to ensure the overall rational operation. The industrial control machine reads the 1200CPU data and displays it on the display screen to enable the central control operator to see and control the start and stop of the pipe belt machine in real time and effectively. The cleaning component is set on the conveyor belt 1. The cleaning component is used to clean the conveyor belt 1. The detection component is set on the conveyor belt 1. The cleaning component is used to detect the movement state of the conveyor belt 1. The detection component adopts the method of address encoder and comprehensive protection instrument. One end uses twisted pair to connect all signals in series and finally uses 485 protocol to transmit to the comprehensive protection instrument, and then the comprehensive protection instrument uses Ethernet The detection instrument signal is transmitted to the PLC in the form of a control line. The other end uses a control line to connect the normally closed points of all signals in series to the secondary circuit of the low-voltage cabinet at the power end to ensure that the equipment is powered off at the moment of a fault. After the central control operator clicks the start button on the screen, the sound and light alarm device will warn five times. The pipe conveyor starts at a preset frequency. When the material is unloaded from the head to the pipe conveyor, the belt gradually rolls into a tube along the direction of rotation and leads the material to the three-way unloading device at the tail end. The belt is gradually spread out and the material falls into the lower equipment through the three-way unloading device. As a circle of the belt is completed, the cleaning mechanism will first use the first polyurethane cleaner 51 and the second polyurethane cleaner 54 for the belt without material at the bottom, and then use the roller brush cleaner 52. Finally Use wind knife to clean the materials stuck on the belt. If human failure factors occur during transportation, the staff on duty nearby can quickly pull the nearby wire rope to drive the pull rope switch 67 connected by the wire rope to stop the belt conveyor. If the motor runs at high speed during transportation and the speed detection device does not detect the corresponding speed of the belt, the signal is transmitted to the PLC and then processed by the PLC logic to send different signals to the host computer to remind the personnel. If the belt deviates at the unfolding end of the head and tail of the conveyor belt 1, the deviation switch will transmit the first-level deviation and second-level deviation signals to the host computer according to the different deviation angles. At the same time, the PLC will make an alarm or shutdown request for the entire system according to the different signals.Similarly, the belt tear-proof detection device 65 and the anti-blocking detector 64 also monitor the belt in real time and feed the signal back to the PLC for processing, and make corresponding countermeasures for the system.

[0045] Specifically, the driving assembly 3 includes a fixed frame 31, a driving roller 32, a servo motor 33 and a reducer 34.

It is used to remove foreign objects, iron parts, etc. to prevent them from scratching the belt. The alarm 66 and the pull-rope switch 67 are arranged on both sides of the conveyor belt 1. When the conveyor belt 1 is turned on, the alarm 66 alarms on the spot and keeps away, and there is a clear warning signal. The installation distance is one group at the head and one group at the tail, and they are installed in pairs on the brackets on both sides of the belt conveyor. The belt conveyor length is 60 meters per group. That is, it can be installed at a position of about 1 meter on both sides of the tubular belt.
