Detailed Description
In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.
As shown in fig. 1, the utility model provides a security system for a gantry crane, which is used for security protection of the gantry crane.
In this embodiment, the gantry crane includes a rotating escalator and a luffing platform.
The security system provided in this embodiment includes: a control unit 5, a first correlation photoelectric sensor 1, a second correlation photoelectric sensor 2, a third correlation photoelectric sensor 3 and an audible and visual alarm 4.
The first correlation photoelectric sensor 1, the second correlation photoelectric sensor 2 and the third correlation photoelectric sensor 3 are all in signal connection with the control unit 5.
The audible and visual alarm 4 is electrically connected with the control unit 5.
The first opposite-shooting type photoelectric sensor 1 is used for being installed at a boarding gate of the gantry crane to detect whether personnel intrude into the boarding gate of the gantry crane.
The second correlation photoelectric sensor 2 is used for being installed at the escalator exit of the gantry crane to detect whether personnel intrude into the escalator exit of the gantry crane.
The third correlation photoelectric sensor 3 is used for being installed at the landing port of the luffing platform of the portal crane so as to detect whether personnel intrude into the landing port of the luffing platform of the portal crane.
The opposite-emission type photoelectric sensor comprises an emitting end and a receiving end, wherein the emitting end emits light, the receiving end receives the light, and if the light emitted by the emitting end is cut off, the receiving end cannot receive the light emitted by the emitting end, then a switching value signal is emitted. The working principle of the correlation photoelectric sensor is common knowledge in the field, and is not repeated here.
In the present embodiment, the audible and visual alarm 4 is used in cooperation with the first correlation type photoelectric sensor 1, the second correlation type photoelectric sensor 2, and the third correlation type photoelectric sensor 3. Specifically, when the light emitted by any of the first, second and third correlation type photoelectric sensors 1, 2 and 3 is cut off, the correlation type photoelectric sensor that emits the cut-off light will send a switching value signal to the control unit 5, and the control unit 5 receives the switching value signal and controls the audible and visual alarm 4 to perform audible and visual alarm.
When the security system is used, the first correlation type photoelectric sensor 1 is firstly arranged at a boarding gate of the gantry crane, the second correlation type photoelectric sensor 2 is arranged at a stair-out opening of a rotary escalator of the gantry crane, the third correlation type photoelectric sensor 3 is arranged at a stair-up opening of a luffing platform of the gantry crane, and the audible and visual alarm 4 is arranged in a cab of the gantry crane.
The security system works: when someone intentionally or unintentionally breaks into the gantry crane, the break-in personnel can cut off the light rays emitted by the corresponding opposite-type photoelectric sensor, the opposite-type photoelectric sensor with the cut-off light rays sends a switching value signal to the control unit 5, and the control unit 5 receives the switching value signal and controls the audible and visual alarm 4 to carry out audible and visual alarm so as to prompt the monitoring personnel to break in.
For example, when a person breaks in from a gate, the person cuts off the light emitted by the first correlation type photoelectric sensor 1 installed at the gate, the first correlation type photoelectric sensor 1 sends a switching value signal to the control unit 5, and the control unit 5 receives the switching value signal and controls the audible and visual alarm 4 to perform audible and visual alarm so as to prompt the monitoring person to break in.
For another example, when a person enters from the escalator (i.e. when the gantry crane works, the person enters the escalator through the boarding gate), the light emitted by the second correlation photoelectric sensor 2 installed at the exit of the escalator is cut off when the person passes through the exit of the escalator, the second correlation photoelectric sensor 2 sends a switching value signal to the control unit 5, and the control unit 5 receives the switching value signal and controls the audible and visual alarm 4 to perform audible and visual alarm so as to prompt the monitoring person to enter.
For example, when a person enters from the landing entrance of the luffing platform (i.e. the person is already at the landing platform position in the working process of the portal crane), the light emitted by the third correlation photoelectric sensor 3 installed at the landing entrance of the luffing platform is cut off when the person passes through the landing entrance of the luffing platform, the third correlation photoelectric sensor 3 sends a switching value signal to the control unit 5, and the control unit 5 receives the switching value signal and controls the audible and visual alarm 4 to perform audible and visual alarm so as to prompt the monitoring person to enter.
