Abstract
The utility model discloses a traveling crane alarm device for linkage of a large crane, a small crane and a main hook, which comprises a traveling crane body, the large crane, the small crane and the main hook. A normally open auxiliary contact of one end of each of main contactors of the large crane, the small crane and the main hook is connected with an alarm lamp in series, and normally open auxiliary contacts of the other ends of the main contactors of the large crane, the small crane and the main hook are connected in series prior to being connected with an alarm sound generator in series. The traveling crane alarm device is simple in structure, exquisite in conception and convenient in use, particularly can effectively monitor regulation violating actions of traveling crane operators on linkage of the large crane, the small crane and the main hook, simultaneously can remind traveling crane operating staff of timely avoiding possible dangerous results brought by the regulation violating actions on linkage of the large crane, the small crane and the main hook, effectively protects personal safety of the operating staff, and is worthy of being greatly popularized.
Description
Technical field
The utility model relates to a kind of elevator machinery, relates in particular to a kind of convenience is carried out safety supervision and management to crane trolley driving three interlock alarm devices.
Background technology
Be applied to forbid in the driving post rules of lifting industry " three interlocks " operation, the operative employee that promptly drives a vehicle operates the cart of driving, dolly, main hook simultaneously and moves simultaneously, because when " three interlocks ", the safety misadventure that thing falls and kills or injure the operating personnel of work under the driving by a crashing object appears hanging easily, it is the operation against rules behavior, but in practice, difficult to moving operation worker " three interlock " to find and supervision, therefore, need from technological layer, effectively supervise and control this moving operation worker " three interlocks ".
The utility model content
The purpose of this utility model is, overcomes the above-mentioned defective of prior art, provides a kind of simple in structure, exquisite composition, monitor the three interlock alarm devices of driving a vehicle easily.
For realizing described purpose, the technical scheme that the utility model provides is as follows: construct a kind of driving three interlock alarm devices, comprise the driving main body, cart, dolly, main hook, an end of the main contactor of described cart, dolly, main hook is often driven secondary contact and is serially connected with alarm lamp respectively, and the other end of the main contactor of described cart, dolly, main hook is serially connected with a warning sound-producing device after often opening the secondary contact series connection again.
The operating voltage of described alarm lamp circuit and warning sound-producing device is 220V.
Principle of work of the present utility model is: under the situation that does not change the driving existing structure, respectively with the cart of driving a vehicle, dolly, the secondary contact two ends serial connection of often opening of the main contactor of main hook goes up the alarm lamp loop, cart, the main contactor of dolly and main hook is when work, its two ends often open the secondary contact closure, its corresponding alarm lamp is lighted work, remind operating personnel and on-the-spot supervisor under the driving, cart, a part or two parts of dolly or main hook are worked, need vigilant, but when three parts are all worked simultaneously, loud alarm sound is sent in the sound-producing device energising work of then reporting to the police, and reminds the operating personnel under driving, moving operation worker " three interlocks " operates against regulations, need emergency contact-avoidance, simultaneously, on-the-spot supervisor can in time find " three interlocks " break rules and regulations action of moving operation worker.
The usefulness of the utility model patent is; simple in structure; exquisite composition; easy to use; particularly can carry out effective monitoring to moving operation worker " three interlocks " break rules and regulations action; the operating personnel that can remind the turner of being expert to do simultaneously in time avoids " three interlocks " dangerous consequences that break rules and regulations action may bring, and actv. has been protected operating personnel's personal safety, and worth industry is widelyd popularize.
Description of drawings
Be further described with regard to the concrete technical scheme that driving three described in the utility model links alarm devices below in conjunction with accompanying drawing and preferred embodiment.
Fig. 1 is schematic circuit diagram of the present utility model.
The specific embodiment
Consult driving shown in Figure 1 three interlock alarm device schematic circuit diagram, comprise the driving main body, cart, dolly, main hook, one end of the main contactor of described cart, dolly, main hook is often driven secondary contact 1,2,3 and is serially connected with alarm lamp 4,5,6 respectively, and the other end of the main contactor of described cart, dolly, main hook is serially connected with a warning sound-producing device 10 after often opening secondary contact 7,8,9 series connection again.
The operating voltage of described alarm lamp circuit and warning sound-producing device 10 is 220V.
For the circuit of the main body of driving a vehicle, be known technology, this is not just giving unnecessary details again.
Above-described only is principle of the present utility model and preferred embodiment.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, also should be considered as belonging to protection domain of the present utility model.
