Description
Technical field
The utility model relates to hoisting crane electrical equipment, is specifically related to a kind of crane classification group restraint device.
Background technology
At present, when hoisting crane uses, operator often ignores working level during rubber tyre gantry crane design, the use hoisting crane of any high strength; When hoisting crane exceeds the working level self born, can not auto-breaking, can not give the alarm, hoisting crane electrical equipment is still working on, and such result often causes hoisting crane to damage, and also may cause serious accident.
Utility model content
The technical matters that the utility model solves there are provided a kind of auto-breaking, automatic alarm, makes the crane classification group restraint device of hoisting crane trouble free service under suitable working level.
Based on above-mentioned purpose, the technical matters that the utility model solves realizes by the following technical solutions:
A kind of crane classification group restraint device, power lead connection control switch, power lead is provided with power light and run indicator, control circuit is divided into two parts, part series signals processing instrument meter apparatus, another part series signals processing instrument meter apparatus mouth, signal transacting meter system is provided with four contactless switchs, be respectively main hook and run contactless switch, auxiliary hook operation contactless switch, trolley travelling contactless switch and cart operation contactless switch, signal transacting meter system mouth connects buzzer phone, and buzzer phone connects total contactless switch.
Further, described main hook runs contactless switch connection main hook read-out.
Further, described auxiliary hook runs contactless switch connection auxiliary hook read-out.
Further, described trolley travelling contactless switch connects trolley travelling read-out.
Further, described cart runs contactless switch connection cart and runs read-out.
The beneficial effects of the utility model are: this patent reduces the damage of hoisting crane, avoids the generation of safety misadventure, can guarantee that hoisting crane carries out work under suitable working level; once exceed rank; by automatic alarm, auto-breaking, plays a very good protection.
Accompanying drawing explanation
Fig. 1 is circuit theory schematic diagram of the present utility model;
Detailed description of the invention
Below by way of Figure of description, set forth the utility model further.
As Fig. 1 indicate, a kind of crane classification group restraint device, power lead connection control switch, power lead is provided with power light 1 and run indicator 2, control circuit is divided into two parts, part series signals processing instrument meter apparatus 13, another part series signals processing instrument meter apparatus mouth 12, signal transacting meter system 13 is provided with four contactless switchs, be respectively main hook and run contactless switch 8, auxiliary hook runs contactless switch 9, trolley travelling contactless switch 10 and cart run contactless switch 11, signal transacting meter system mouth 12 connects buzzer phone 14, buzzer phone 14 connects total contactless switch 15, main hook runs contactless switch 8 and connects main hook read-out 4, auxiliary hook runs contactless switch 9 and connects auxiliary hook read-out 5, trolley travelling contactless switch 10 connects trolley travelling read-out 6, cart runs contactless switch 11 and connects cart operation read-out 7.
Principle of work: each mechanism of hoisting crane is as comprised main hook, auxiliary hook, cart, dolly, the number of starts at the appointed time, the information input signal processing instrument meter apparatus such as time of run, signal transacting meter system 13 gathers the actuation signal of each mechanism, and starts timing.When the number of starts in hoisting crane each mechanism specified time and time of run exceed the working level of rubber tyre gantry crane design, the buzzer phone 14 being placed in operator's compartment will give the alarm, if time delay a period of time hoisting crane does not still stop work, instrument will send instruction, cut off hoisting crane working power, stop it to work on.
Preferred embodiment of the present utility model is only, not in order to limit the utility model above.All make within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
