Description
Technical field
The utility model relates to the servicing unit on crane, excavator, is specially transmission line of electricity anti-collision line apparatus.
Background technology
Along with soaring all the way of the mineral matter prices such as aluminite, under the driving of interests, it is in full flourish that the random phenomenon of adopting is dug in private, brought unprecedented potential safety hazard to the operation of each electric pressure transmission line of electricity, often because of crane, excavation chance error, touch operating transmission line of electricity, the large area blackout of transmission line of electricity breaking occurs, even can be expanded into power grid accident, power supply reliability cannot be guaranteed, gives the production of enterprise, the people's life has brought inconvenience.
Summary of the invention
The utility model in order to solve transmission line of electricity because crane, excavator touch generation breaking by mistake, and cause and the problem of large area blackout provide transmission line of electricity anti-collision line apparatus.
The utility model is to adopt following technical scheme to realize: transmission line of electricity anti-collision line apparatus, comprise range cells and control module, range cells comprises inner with the first single-chip microcomputer apart from comparison program, the input end of the first single-chip microcomputer is connected with distance measuring sensor, the output terminal of the first single-chip microcomputer is connected with audible-visual annunciator and wireless launcher, the power end of the first single-chip microcomputer, the power end of wireless launcher and distance measuring sensor is connected, the power end of the first single-chip microcomputer is also connected by the normally opened contact of auxiliary reclay and the output terminal of accumulator, the coil of auxiliary reclay is connected with the output terminal of electromagnetic inductor, control module comprises second singlechip, the power end of second singlechip is all connected with accumulator with the power end of wireless receiver, the input end of second singlechip is connected with the output terminal of wireless receiver, the output terminal of second singlechip is connected with the coil of timing relay, and the normally closed contact of timing relay is connected on the startup loop of crane or excavator.
The distance comparison program writing in single-chip microcomputer is the known program of those skilled in the art.
During use, the range cells of this transmission line of electricity anti-collision line apparatus is fixed on to the top of the arm of crane or excavator, control module is placed in the pilothouse of crane or excavator, when the arm of crane or excavator approaches live wire, electromagnetic inductor senses electromagnetic wave, make coil charged of auxiliary reclay, the normally opened contact of auxiliary reclay is closed, distance measuring sensor is measured the distance between arm and live wire and is transferred in single-chip microcomputer, the first single-chip microcomputer is by the distance recording and secure threshold comparison, when the distance recording is less than secure threshold, the first Single-chip Controlling audible-visual annunciator is reported to the police, remind the driver of crane or excavator, the first single-chip microcomputer is to wireless launcher control signal simultaneously, wireless launcher sends wireless signal, wireless receiver in control module receives wireless signal, wireless electric wire connecting junction is to second singlechip signal, second singlechip output voltage signal is to timing relay, the normally opened contact of timing relay disconnects time delay, if within the time that the time delay of the normally opened contact of timing relay disconnects, driver does not move to the arm of crane or excavator in safe range, be that the arm that records of distance measuring sensor and the distance between live wire are less than secure threshold, the normally opened contact of timing relay disconnects, crane or excavator quit work, if within the time that the time delay of the normally opened contact of timing relay disconnects, driver moves to the arm of crane or excavator in safe range, be that the arm that records of distance measuring sensor and the distance between live wire are greater than secure threshold, the first single-chip microcomputer does not send control signal to wireless launcher, crane or excavator are normally worked, so just guaranteed the safe and reliable operation of transmission line of electricity.
The transmission line of electricity anti-collision line apparatus that the utility model provides can make crane or excavator arm when work avoid encountering transmission line of electricity, and then has guaranteed the safe and reliable operation of transmission line of electricity, has ensured the production of enterprise, the people's life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
