Abstract
The present invention discloses an electromagnetic positioning apparatus of a rotation lifting hook. The electromagnetic positioning apparatus comprises an electromagnet, a positioning pin, a positioning gear disc, a connection frame, and a position limitation switch, wherein the electromagnet is vertically arranged on a lifting hook holder, the end is connected with a positioning pin shaft through the connection frame, and the positioning pin shaft is inserted into a positioning hole of the positioning gear disc and pulled out of the positioning hole of the positioning gear disc through power-on and power-down of the electromagnet. According to the present invention, the circuit is further improved so as to achieve rotation of the lifting hook at any angles of 0-360 DEG, achieve accurate positioning of the lifting hook at angles of 90 DEG, 180 DEG and 270 DEG, and reduce operator labor intensity; and mechanical positioning of the electromagnet is adopted as a safety device for the rotation lifting hook apparatus so as to effectively increase accuracy and safety of the rotation apparatus, and the apparatus can be widely used in crane production.
Description
Technical field
The present invention relates to the rubber tyre gantry crane design field, relate in particular to a kind of shackle hook electromagnetic location device.
Technical background
Rely on the suspension hook group to be connected weight during hoisting crane lifting weight with rope, arbitrarily angled or weight need accurately turn an angle if weight need rotate the 0-360 degree, traditional hoisting crane can only rely on manpower or rotate by common shackle hook crawl, but when hoisting capacity is big, artificial or common shackle hook operates just difficult unusually, and has certain potential safety hazard; There is the phenomenon of locate failure in common shackle hook.
Summary of the invention
Technical matters to be solved by this invention is: a kind of shackle hook electromagnetic location device is provided, realizes the arbitrarily angled crawl rotation of suspension hook 0-360 degree by position fixing system; Realize suspension hook revolve turn 90 degrees, the accurate location of 180 degree, 270 degree; Phenomenon by electromagnetic location device solves suspension hook locate failure can realize manual rotation.
Technical scheme of the present invention is: a kind of shackle hook electromagnetic location device comprises: electromagnet, locating dowel pin, location fluted disc, link span, limit switch; Described electromagnet vertically is installed on the suspension hook support, and its end links to each other by link span with alignment pin, and alignment pin realizes inserting and extracting in the knock hole of location fluted disc by the energising and the outage of electromagnet.
Further, on the described alignment pin electric machine spacing switch is housed.
Further, described positioning of rotating system is provided with 90 degree limit switches and 180 degree limit switches, and realizes the arbitrarily angled rotation of 0-360 degree by the particular electrical circuit system.
Further, described location fluted disc is provided with oval knock hole.
Further, be provided with anti-wear sleeve between described alignment pin and the shackle hook support.
Further, described alignment pin end is provided with pin hole, when breaking down, to lift on the alignment pin, insert pin in pin hole, this moment, alignment pin was in released state with the location fluted disc, again the chain of the chain-type limited torque coupler under the engine installation is removed, can be realized manual rotation.
After having adopted technique scheme, the invention has the beneficial effects as follows: realize the positive and negative rotation of the suspension hook arbitrarily angled crawl of 0-360 degree; Realize suspension hook revolve turn 90 degrees, the accurate location of 180 degree, 270 degree; (when needing Rotate 180 degree location, can skip 90 degree and directly rotate to 180 degree) makes suspension hook accurate positioning, safety.The present invention has realized the accurate control of lifting weight, has effectively reduced operator's labour intensity, has more reduced the potential safety hazard in the use.
Description of drawings
Fig. 1 is a structural representation of the present invention;
The specific embodiment
Below, further set forth the present invention by Figure of description;
According to shown in Figure 1, with shackle hook winding energize, this moment, electromagnet 4 was in "on" position, pulling link span 3, affect alignment pin 2 simultaneously, make alignment pin 2 extract the oval knock hole of location fluted disc 1, the upper end of alignment pin 2 connect electric switch 11 with motor and contacted this moment, and motor 7 is started working; Motor 7 is delivered to location fluted disc 1 with moment of torsion by reductor, plunging joint 6 and miniature gears, suspension hook 5 realization rotations this moment.
In the electric cabinet 10 AC contactor is installed, by particular electrical circuit system and 9 combineds action of 180 degree limit switches, 8,90 degree limit switches, the accurate location of realizing suspension hook positive and negative rotation of the arbitrarily angled crawl of 0-360 degree and 90 degree, 180 degree, 270 degree.When limit switch was opened, the electromagnet outage made 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 above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
