Abstract
The utility model discloses a crane travelling limiter, and aims at designing a crane travelling limiter with good use effect and reasonable structure. According to the technical scheme disclosed by the utility model, the crane travelling limiter comprises a shell and a self-lock switch, wherein a revolving member is arranged inside the shell; an anti-collision rod is arranged at the upper part of the revolving member; the bottom part of the revolving member is tightly attached to an elastic trigger; and the self-lock switch is arranged corresponding to a contact of the elastic trigger. The crane travelling limiter is reasonable in structure and good in use effect, can effectively prevent the crane from colliding with the other equipments, and ensures stable operation of the equipment and the personal safety of operating personnel.
Description
Technical field:
The utility model relates to hoisting crane, particularly a kind of crane travelling limiter.
Background technology:
The crane in bridge type that now uses and transfer crane are in order to use safety, other equipment of hoisting crane and ground that prevent bump, range limiter all is installed on their orbit, but existing range limiter structure is comparatively complicated, cost is higher, installation procedure is also more numerous and diverse, has increased production and the design cost of crane facility, is unfavorable for the production and selling of hoisting crane.
Summary of the invention:
The purpose of this utility model is good, the rational in infrastructure crane travelling limiter of a kind of result of use of design.
The technical solution of the utility model is, a kind of crane travelling limiter, it comprises housing, self-lock switch, it is characterized in that: be provided with tumbler in housing, the top of tumbler is equipped with crash bar, and the bottom of tumbler and elasticity binary pair are close to, and the contact position correspondence of elasticity binary pair is equipped with self-lock switch.
The utility model is rational in infrastructure, and result of use is better, can actv. prevents that hoisting crane and miscellaneous equipment from touching, and has guaranteed the personal safety of smooth operation and the operating personal of equipment.
Description of drawings:
Fig. 1 is structural representation of the present utility model, Fig. 2 is the structural representation of the second implementation of the present utility model, Fig. 3 is the structural representation of the third implementation of the present utility model, Fig. 4 is the structural representation of the 4th kind of implementation of the present utility model, and Fig. 5 is the structural representation of the 5th kind of implementation of the present utility model.
The specific embodiment:
Describe by reference to the accompanying drawings embodiment in detail, a kind of crane travelling limiter, it comprises housing 5, self-lock switch 4, be provided with tumbler 2 in housing, the top of tumbler is equipped with crash bar 1, and the bottom of tumbler and elasticity binary pair 3 are close to, and the contact position correspondence of elasticity binary pair is equipped with self-lock switch.Principle of work of the present utility model is, because in a single day crash bar is touched, can drive tumbler, tumbler one rotates or is offset and will trigger the elasticity binary pair, smash middle self-lock switch by the contact of elasticity binary pair, self-lock switch is connected with general supply, and then can be with the supply disconnecton of hoisting crane.Assurance equipment in time stops operation, has safeguarded the stable of equipment, avoids occurring safety misadventure.
