Abstract
The invention discloses a stroke limiter for cranes, and aims to design a stroke limiter for the cranes, which has good using effect and reasonable structure. The technical scheme of the invention is that the stroke limiter for the cranes comprises a casing and a self-locking switch, wherein a rotation part is arranged in the casing; a bumper bar is installed at the upper part of the rotation part; the bottom of the rotation part is in close contact with an elastic trigger; and the self-locking switch is installed in the contact terminal position of the elastic trigger correspondingly. The stroke limiter for cranes provided by the invention has reasonable structure and good using effect, and can effectively prevent a crane from hitting against other equipment, so that the stable operation of the equipment and the personal safety of the operator are ensured.
Description
Technical field:
The present invention relates to hoisting crane, particularly a kind of crane travelling limiter.
Background technology:
Present employed crane in bridge type 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:
It is good to the objective of the invention is to design a kind of result of use, crane travelling limiter rational in infrastructure.
Technical scheme of the present invention is, a kind of crane travelling limiter, it comprises housing, self-lock switch, it is characterized in that: in housing, be provided with tumbler, 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 present invention 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 invention, Fig. 2 is the structural representation of the second implementation of the present invention, Fig. 3 is the structural representation of the third implementation of the present invention, Fig. 4 is the structural representation of the 4th kind of implementation of the present invention, and Fig. 5 is the structural representation of the 5th kind of implementation of the present invention.
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, in housing, be provided with tumbler 2, 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 invention 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.
