Problems solved by technology
However, due to the heavy dust in the working environment of the bag inserting machine equipment, the high environmental noise, and the relatively fast rotation speed of the bag inserting machine equipment, it is difficult for the operator to touch when an emergency occurs such as improper operation or fainting by the equipment. to the emergency stop device and call for help, resulting in a personal injury accident
Therefore, the personal safety protection performance of the bag inserting machine equipment needs to be further improved to reduce the occurrence of safety accidents

The invention relates to a station personal injury prevention protection system and a station personal injury prevention protection device and relates to the field of mechanical equipment. The personal safety of a station operating worker is improved in the operation through the system and the device. According to the technical scheme, the station personal injury prevention protection system comprises mechanical equipment, a protection platform, a gravity switch, a first relay, a first control loop and a second control loop. The mechanical equipment is provided with a start-stop control unit; the protection platform is provided with a load bearing area; the gravity switch is arranged on the protection platform, and the gravity switch is provided with an inductive region and a first gravity contact switch; the first gravity contact switch is closed when gravity input exists in the load bearing area and is disconnected without the gravity input; the first relay is provided with a coil and a normally open contact switch; the first control loop comprises the coil and the gravity contact switch which are connected in series; and the second control loop comprises the normally open contact switch and the start-stop control unit which are connected in series.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment protection devices, in particular to a post personal injury protection system and a post personal injury protection device. Background technique [0002] The bag inserting machine is an important equipment for bagged cement packaging. In most cement enterprises now, the bag inserting machine equipment generally uses manual bag inserting, and the operator needs to stand at a relatively fixed operating station next to the bag inserting machine equipment to operate the equipment. The bag inserting machine equipment has an operation box, which is equipped with an emergency stop button and an equipment start button. The bag inserting machine equipment also has an opening and closing control unit. The equipment starting button is a part of the opening and closing control unit. When looping, press the start button to control the opening and closing control unit to connect or disconnect, so ...
