Problems solved by technology

This method not only has a high cost for a single transformation, but also has a long cycle, and is not suitable for promotion. If multiple grinding machines are transformed at the same time, the transformation cost will be further increased. At the same time, this transformation itself still has certain safety hazards; The working environment of the computer is relatively harsh, and the reliability of electronic products cannot absolutely meet the demand for safety protection.

Embodiment

[0024] Example: Taking the habitual illegal operation behavior of a single grinder during operation as an example, four photoelectric sensors are used to monitor the habitual illegal operation of a single grinder during operation, all of which are placed on the front of the grinder XZ On the wall of the axial projection surface, two sensors (No. 1 and No. 2) are placed on the wall 30mm to 50mm above the tangent line of the highest point of the protective cover of the two grinding wheel discs. Human body; the other two sensors (No. 3 and No. 4) are placed on the inner side of the same height as No. 1 and No. 2 sensors, and their function is to detect the human body standing on the side of the grinder. The location of the distribution box depends on the specific working environment, and there are no special requirements. Specific steps:

[0025] This equipment has two states of automatic warning control and prompt alarm warning control:

[0026] 1. Automatic alert control stat...

Abstract

The invention provides a grinding machine safety operation monitoring protection system. The grinding machine safety operation monitoring protection system comprises a PLC, photoelectric sensors, a breaker, a relay, and alarm devices. The photoelectric sensors are connected with the input end of the PLC, the breaker, the relay and the alarm devices are connected with the output end of the PLC, andmultiple photoelectric sensors and multiple alarm devices are arranged on each grinding machine. Through monitoring of the photoelectric sensors, habitual unsafe operating behaviors in the operationprocess of the grinding machine can be corrected in time, and the necessary power failure shutdown means can be taken to safely protect an operator.

Description

technical field [0001] The invention relates to a monitoring and protection system for safe operation of a grinder. Background technique [0002] It is clearly stipulated in the safety operation regulations of the grinder: the operator should stand on the side of the grinder, and it is strictly forbidden to stand on the front; it is strictly forbidden for two people to use a grinder at the same time. In the process of actually operating the grinder, many operators are prone to habitual unsafe operating behaviors such as standing in front of the grinder or using a grinder by two people at the same time. At present, first, there is no suitable mature equipment for safety protection against this habitual unsafe behavior that grinder operators are prone to produce on the market. Second, in order to correct the habitual unsafe operation behavior of the operators during the operation of the grinder, some enterprises that attach great importance to safety production and meet the s...
