Abstract
The utility model relates to a weight display and overweight protection device of a portal crane, and is used for conducting real-time monitoring, display and overload protection on the hoisting loads of the portal crane. The device comprises a weight sensor, a crane trolley remote control cabinet, a crane main PLC control system, and a touch screen, wherein, the crane trolley remote control cabinet comprises an A/D converter and a crane trolley PLC remote control substation; the weight sensor is connected with the A/D converter; the A/D converter is connected with the crane main PLC control system; and the crane main PLC control system is connected with the touch screen. The utility model improves the capability of resisting various types of interferences, greatly improves weight display accuracy, and ensures that the safety protection performance is more accurate.
Description
(1) technical field
The utility model relates to a kind of transfer crane, is specifically related to a kind of transfer crane weight and shows and overweight fender guard.Be used for to transfer crane play that a heavy lift is monitored in real time, demonstration and overload protection.Belong to the elevator machinery technical field.
(2) background technology
Before the utility model was made, transfer crane weight in the past showed and overweight fender guard, is made up of the independent overweight fender guard of a cover, comprises load sensor, amplifier and controller, telltale etc.Its basic functional principle is by the detected electric signal of load sensor (analog quantity), by common shielded cable through girder drag chain device, access is located at the overweight control box of transfer crane of driver's cab, after the amplifier modulation, input a/d converter converts digital quantity input single-chip microprocessor system to, system is according to designing program, make early warning respectively or the control output (output signal is the switching value signal) of transfiniting after differentiating each operating mode, and show operating condition by LED, relevant scheme drawing is seen Fig. 1.Because the transfer crane span of building is bigger, the connection line between the overweight control box of load sensor and transfer crane is very long, disturbed by the frequency converter high-frequency harmonic, and it is inaccurate to make that weight shows, overweight output signal instability.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of transfer crane weight that can improve the various interference performances of opposing to show and overweight fender guard.
The purpose of this utility model is achieved in that a kind of transfer crane weight shows and overweight fender guard; described device comprises load sensor, crane carriage Long-distance Control cabinet, hoisting crane master PLC control system and touch-screen; described crane carriage Long-distance Control cabinet comprises A/D converter and crane carriage PLC Long-distance Control substation; load sensor links to each other with described A/D converter; A/D converter links to each other with described hoisting crane master PLC control system, and hoisting crane master PLC control system links to each other with touch-screen.
The beneficial effects of the utility model are:
The utility model is with the load sensor signal; directly import in the PLC in the monkey Long-distance Control cabinet by amplifier; then by Optical Fiber Transmission in the electric room on the hoisting crane master PLC control system; computing by the PLC programmable controller; show associated weight on touch-screen, the programming by the PLC programmable controller realizes overweight protection to hoisting crane.Improved the various interference capability of opposing like this, weight shows that accuracy rate significantly improves, and the safety guard-safeguard performance is more accurate.

Fig. 1 is the scheme drawing of transfer crane weight demonstration in the past and overweight fender guard.
Fig. 2 is the scheme drawing of demonstration of the utility model transfer crane weight and overweight fender guard.
Reference numeral among the figure:
(5) specific embodiment
Referring to Fig. 2, Fig. 2 is the scheme drawing of demonstration of the utility model transfer crane weight and overweight fender guard.As seen from Figure 2; the utility model transfer crane weight shows and overweight fender guard; comprise load sensor, crane carriage Long-distance Control cabinet, hoisting crane master PLC control system and touch-screen; described crane carriage Long-distance Control cabinet comprises A/D converter and crane carriage PLC Long-distance Control substation; load sensor links to each other with described A/D converter; A/D converter links to each other with described hoisting crane master PLC control system, and hoisting crane master PLC control system links to each other with touch-screen.
