Description

Lifting hook is servo-actuated latch hook device

Technical field

The utility model is related to lifting hook field, and latch hook device is servo-actuated more particularly to a kind of lifting hook.

Background technology

At present, self-contained whole unloading is not quite similar with the conversion device structure form of self-unloading in the lifting hook of in the market.But it is existing There is the latch hook device in technology generally to be controlled with electrically using single hydraulic pressure, in order to realize that it is related zero that its control needs Part is various because when complex structure, installation fee, it is relatively costly.Further, since there is also behaviour by mistake by hydraulic pressure and electrical control The possibility of work.

Utility model content

For above the deficiencies in the prior art, latch hook device is servo-actuated the utility model proposes a kind of lifting hook, it has Easy for installation, low cost and in the absence of the effect of maloperation etc..

To reach above-mentioned purpose, a kind of lifting hook of offer of the present utility model is servo-actuated latch hook device, including underframe, is arranged on Front beam and rear cross beam, lifting hook, connecting rod and latch hook assembly on underframe, the lifting hook include armstand, transverse arm and extension Hook, the lifting hook is pivotably connected by transmission device with the front beam, and the transverse arm of the lifting hook passes through lifting hook Rotating shaft is connected with one end of the connecting rod；

The latch hook assembly includes " people " shape latch hook, limited block and fastener, and the upper end of " people " the shape latch hook can pivot It is fixed on the front beam with turning, the one end below " people " the shape latch hook is fixedly connected with the connecting rod, " people " shape The other end below latch hook is grab, and the limited block sets on front beam and connects with connecting rod positioned in " people " the shape latch hook The top of the end for connecing, the fastener is arranged on the rear cross beam and is engaged with the grab of " people " the shape latch hook.

By said structure, the beneficial effects of the utility model are easy for installation, reduction action related components；Cost It is low, it is not necessary to which that single hydraulic pressure is electrically controlled；3rd, be not in loss that maloperation brings.
