Abstract
The invention discloses an European type rotating safety hook, which comprises a rotating control device, a hook body and a transmission gear, wherein the neck of the upper end of the hook body is connected with the transmission gear, the rotating control device is connected with the transmission gear and consists of a motor and a rotating control unit, the rotating control unit is electrically connected with the motor, an output shaft of the motor is connected with the transmission gear, the rotating control unit consists of a master controller, a driving circuit and a timer, and the driving circuit and the timer are electrically connected with the master controller; a locking stopper piece is further arranged at the neck of the hook body and can seal an opening of the hook body. Through the mode, the European type rotating safety hook has a function of precise control on a rotation angle, as well as a self-locking function, and the lifting reliability and stability can be guaranteed.
Description
Technical field
The present invention relates to weight-lifting equipment accessory field, particularly relate to a kind of European spin safe hook.
Background technology
Current hoisting crane sling in harbour, warehouse, building ground large item time, all need to use shackle hook, and rotate with electric machine control suspension hook.But traditional shackle hook accurately can not control the angle that suspension hook rotates, and can not produce a desired effect under the working environment of ask for something precise manipulation.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of European spin safe hook, has and accurately controls the anglec of rotation and auto-lock function, guarantees lifting reliability and stability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of European spin safe hook, comprise: rotating control assembly, coupler body and transmission gear, the upper end neck of described coupler body is connected with described transmission gear, described rotating control assembly is connected with described transmission gear, described rotating control assembly comprises: motor and the rotation control unit be electrically connected with described motor, the output shaft of described motor is connected with described transmission gear, and described rotation control unit comprises: primary controller and the driving circuit be electrically connected with described master controller and time meter; Also be provided with locking catch at the neck place of described coupler body, described locking catch can close the opening part of described coupler body.
In a preferred embodiment of the present invention, described coupler body section is trapezoidal, and its trapezoidal large end is interior, and small end outside.
In a preferred embodiment of the present invention, described coupler body is made up of high-quality low-carbon alloy steel.
The invention has the beneficial effects as follows: the present invention controls the electric machine rotation time by the primary controller in rotating control assembly and time meter, thus accurately control the anglec of rotation of coupler body, and with locking catch on coupler body, the obscission of weight in hoisting process on coupler body can be prevented, therefore the present invention has accurately the control anglec of rotation and auto-lock function, guarantees lifting reliability and stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of European spin safe hook one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, coupler body, and 2, transmission gear, 3, rotating control assembly/motor, 4, locking catch, 5, output shaft.
Detailed description of the invention
