Accompanying drawing explanation
Fig. 1 is the electrical connection diagram of the belt conveyor safety device of the utility model embodiment;
Fig. 2 is the structural representation of the approach switch of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, the embodiment in the application and the feature in embodiment be combination in any mutually.
As shown in Figure 1, belt conveyor safety device, comprises approach switch and conveyer control circuit;
Described approach switch and described conveyer control circuit are connected on the two ends of power supply, the distance of the sensitive surface of detected material and described approach switch be less than or equal to detect apart from time, described approach switch is in closure state, the distance of the sensitive surface of detected material and described approach switch be greater than detect apart from time, described approach switch is in off-state.
When there being object to shift to approach switch, and while being close to certain distance, approach switch just has " perception ", and switch just can move, and this distance is called and detects distance.
As shown in Figure 2, wherein, described approach switch comprises successively connected induced magnetism tank, high-frequency oscillating circuits, shaping detecting circuit, signal processing circuit, switching value output circuit.
The distance that detects of described approach switch is 0.1mm to 5cm.
Belt conveyor security protection system, comprise belt conveyor safety device and band conveyor, described band conveyor is connected with the conveyer control circuit of described protective device, described band conveyor is provided with cleaning grille guard, and described approach switch is fixed on the entrance of the cleaning grille guard of band conveyor.
Increasing cleaning grille guard, can be door shape structure so that working environment is clean and tidy, and belt conveyor tail grille guard switch gate clear away waste is provided; Approach switch, for control loop change-over swith signal.
Approach switch detects sensitive surface and the degree of closeness of clearing up grille guard, after approach switch inter-process, convert on-off signal to, described approach switch and described conveyer control circuit are connected on the two ends of power supply, band conveyor is given in the situation of electricity operation, approach switch " closure ", when cleaning grille guard is opened, cleaning grille guard leaves approach switch sensitive surface, approach switch switches to "off" by " closure ", and conveyer control circuit disconnects the work that shuts down; When clearing up or having overhauled, cleaning grille guard is closed, and approach switch sensitive surface senses cleaning grille guard, and approach switch switches to " closure " by "off", the closed band conveyor normal operation work of conveyer control circuit.
