Tunnel safety rules and common troubleshooting methods

The grille steel frame is commonly used as the initial support system for tunnel construction. The “8”-shaped skeletal grid is widely used due to reasonable force. The eight-character molding machine replaces thermal processing with mechanized machining, which not only improves work efficiency but also effectively reduces the strength of manual labor. Compared with manual processing, the use of mechanical processing can reduce the investment in labor costs.

Safety requirements for the operation of the squash ribs equipment:

(1) After the operator has been trained, he/she can wear the labor protection (safety helmet, overalls, work gloves, work shoes, etc.) before operating the machine;

(2) The operator must stick to his/her job and must not leave without permission while working. When you leave the equipment, you must stop the machine and explain the equipment to the monitor.

(3) It is forbidden to use equipment that exceeds specifications and overload;

(4) Check the machine before starting the machine to ensure that there are no foreign objects or obstacles around the machine;

(5) When starting work, it is forbidden to touch the machine and the workpiece;

(6) Non-operators are prohibited from entering the work area;

(7) It is forbidden to adjust or maintain the equipment during work. It is necessary to stop the power supply and shut down the power supply and hang a warning sign.

(8) When more than one person cooperates with the operation, be sure to notify other personnel before performing any operation and confirm that understanding of intentions can be performed;

(9) Do not disassemble the safety protection device and open the door of the distribution box without permission. If the equipment fails, it will be shut down immediately and it can be used after being repaired.

Octagonal rib common faults and troubleshooting

(1) The main power supply is not powered on, check whether the incoming power supply voltage is normal;

(2) The entire device is unable to work. Check if each "emergency stop" button is pressed. If any one of them is pressed, the device will be able to work normally after release.

(3) The fuel tank does not advance, check whether the power of the oil pump is turned on; if the oil pipe is squeezed.
