Detailed Description
The invention will be described in further detail with reference to the following drawings and specific examples, which are intended to illustrate and not to limit the invention:
as shown in fig. 1, the safety protection system for a bucket wheel machine of the present invention comprises a plurality of early warning devices disposed above a belt 2; the early warning device comprises a bracket, a control unit, a photoelectric protection device, a warning mark, an alarm device, a voice intercom device, a communication module and a power supply; the control unit, the photoelectric protection device, the warning mark, the voice intercom device, the communication module and the power supply are all arranged on the bracket; a photoelectric curtain wall 1 is formed between the photoelectric protection devices; the photoelectric protection device, the alarm device, the voice intercom device and the communication module are respectively connected with the control unit, and the communication module is communicated and interconnected with the operating console of the bucket wheel machine 3; the early warning device is powered by a power supply.
The photoelectric protection device consists of a light projector and a light receiver. The projector emits modulated infrared light, which is received by the light receiver to form one protecting net, and when some object enters the protecting net and some light is blocked by the object, the light receiver circuit will respond immediately via the inner control circuit, so that one signal is output to the output part for the emergency brake of machine tool, such as punch, press, etc. A plurality of infrared transmitting tubes are arranged at equal intervals on the photoelectric protection device on one side of the photoelectric curtain wall 1, the infrared receiving tubes with the same number and the same arrangement are correspondingly arranged on the other side of the photoelectric curtain wall, and each infrared transmitting tube corresponds to one corresponding infrared receiving tube and is arranged on the same straight line. When no barrier exists between the infrared transmitting tube and the infrared receiving tube on the same straight line, the modulation signal (optical signal) sent by the infrared transmitting tube can smoothly reach the infrared receiving tube. After the infrared receiving tube receives the modulation signal, the corresponding internal circuit outputs low level, and under the condition of an obstacle, the modulation signal (optical signal) sent by the infrared transmitting tube can not smoothly reach the infrared receiving tube, at this moment, the infrared receiving tube can not receive the modulation signal, and the output of the corresponding internal circuit is high level. When no object passes through the light curtain, the modulated signals (light signals) sent by all the infrared transmitting tubes can smoothly reach the corresponding infrared receiving tube on the other side, so that all the internal circuits output low level. Thus, the presence or absence of an object can be detected by analyzing the state of the internal circuit.
In a preferred embodiment of the present invention, the support is a lifting structure.
