Abstract

The utility model discloses an electromagnetic positioning device for a shackle hook. The electromagnetic positioning device comprises an electromagnet, a positioning pin shaft, a positioning fluted disc, a connecting frame and a limiting switch, wherein the electromagnet is vertically mounted on a hook support, and the tail end of the electromagnet is connected with the positioning pin shaft through the connecting frame; and the positioning pin shaft is inserted into and pulled out of the positioning hole of the positioning fluted disc through powering on and off the electromagnet. The electromagnetic positioning device is also improved on the aspect of circuit; and the electromagnetic positioning device is capable of realizing the rotation of the hook for any angle from 0 to 360 degrees, or accurate positioning of the hook at 90 degrees, 180 degrees and 270 degrees; therefore, the labor intensity of an operator is reduced; the mechanical positioning of the electromagnet is used as a safety device of the shackle hook device, so that the accuracy and safety of the shackle hook device are effectively improved; and the electromagnetic positioning device for the shackle hook can be widely applied to manufacture of cranes.

Description

A kind of shackle hook electromagnetic locator

Technical field

The utility model relates to the rubber tyre gantry crane design field, relates in particular to a kind of shackle hook electromagnetic locator.

Background technology

During the crane hanging component weight, rely on the suspension hook group to be connected weight with rope, if weight need to rotate 0-360 degree, arbitrarily angled or weight need to accurately turn an angle, traditional hoisting crane can only rely on manpower or rotate by common shackle hook crawl, but when hoisting capacity is larger, artificial or common shackle hook operates just extremely difficult, and has certain potential safety hazard; There is the phenomenon of locate failure in common shackle hook.

The utility model content

Technical problem to be solved in the utility model is: a kind of shackle hook electromagnetic locator is provided, by position fixing system, realizes the arbitrarily angled crawl rotation of suspension hook 0-360 degree; Realize the accurate location of suspension hook 90-degree rotation, 180 degree, 270 degree; Solve the phenomenon of suspension hook locate failure by electromagnetic locator, can realize manual rotation.

The technical solution of the utility model is: a kind of shackle hook electromagnetic locator comprises: electromagnet, alignment pin, location fluted disc, link span, limit switch; Described electromagnet vertically is installed on suspension hook support, its end is connected by link span with alignment pin, alignment pin is by energising and the outage of electromagnet, realize inserting and extract in the knock hole of location fluted disc, the rotation position fixing system is provided with 90 degree limit switches and 180 degree limit switches, and realizes 0-360 degree Arbitrary Rotations by Circuits System.

Further, the electric machine spacing switch is equipped with in described alignment pin upper end.

Further, described location fluted disc is provided with oval knock hole.

Further, be provided with anti-wear sleeve between described alignment pin and shackle hook support.

Further, described alignment pin end is provided with pin hole, when breaking down, to on alignment pin, lift, insert pin in pin hole, now alignment pin and location fluted disc are in released state, again the chain of the chain-type torque limiter coupling under engine installation is removed, can be realized manual rotation.

After having adopted technique scheme, the beneficial effects of the utility model are: realize the positive and negative rotation of suspension hook 0-360 arbitrarily angled crawl of degree; Realize the accurate location of suspension hook 90-degree rotation, 180 degree, 270 degree; (while needing Rotate 180 degree location, can skip 90 degree and directly rotate to 180 degree) makes suspension hook accurate positioning, safety.The utility model has been realized the accurate control of lifting weight, effectively reduces operator's labour intensity, has more reduced the potential safety hazard in the use procedure.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

The specific embodiment

Below, by Figure of description, further set forth the utility model;

Shown in Fig. 1, the shackle hook group is switched on power, now electromagnet 4 is in "on" position, pull link span 3, affect alignment pin 2 simultaneously, make alignment pin 2 extract the oval knock hole of location fluted disc 1, now the upper end of alignment pin 2 connects electric switch 11 with motor and contacts, and motor 7 is started working; Motor 7 is delivered to location fluted disc 1 by moment of torsion by reductor, plunging joint 6 and miniature gears, and now suspension hook 5 is realized rotation.

In electric cabinet 10, AC contactor is installed, by Circuits System and 180 degree limit switch 8,90 degree limit switch 9 combineds action, the accurate location of realizing suspension hook 0-360 degree positive and negative rotations of arbitrarily angled crawl and 90 degree, 180 degree, 270 degree.When limit switch is opened, the electromagnet outage, make link span 3 affect alignment pin 2 to insert in the knock hole of location fluted disc 1 downwards by deadweight, and while alignment pin 2 upper ends and motor connect electric switch 11 and leave, and motor 7 outages stop operating.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
