The invention discloses a crane for water conservancy construction. The crane structurally comprises a crane body, a rear fixed plate, a boom, a winding ring and a hook head. The rear fixed plate is welded to the rear end surface of the crane body, and the rear fixed plate is connected to the tail end of the boom through a hinge. A to-be-hooked part of an object is moved into an inner ring position of a hook body, a reverse body of the object is pressed inwards, and when the size of an object hook is just right, the reverse body is continuously pressed. When one end of a warped body inside a middle rod is stressed, a connection part at the other end is driven reversely while the single end is stressed, when the hook is just full of the hooked part, a direction hook presses inwards, an auxiliary head extends outwards to protect the object, an in-situ stress ball carries out limiting along an inner pressing opening, an abutting ball abuts against the stress ball in the moving process ofthe inner pressing opening, the connecting portion fluctuates to a certain degree, and the outer side of the connecting portion is abutted for reverse pushing, so that when an outer ring abuts againstthe connecting portion, a force in the largest range exists, and a reverse hook of the crane is fixed when the object is hoisted.

    本发明公开了一种水利施工用吊车,其结构包括车体、后固板、吊臂、绕线圈、钩头,后固板焊接于车体后端表面,后固板与吊臂末端铰链连接,将物体所要勾住的部位移入钩体内圈位置,将其反向体往内压,当物体钩大小刚好时,将会持续对反向体进行压动,当中杆内部的翘体一端受力时,单端受力时,将会把另一端的衔接部位往反向带动,能够在勾住的部位刚好占满钩子时,将方向钩往内压动,辅助头往外伸出对物体进行防护,置于原地的受力球将会顺着内压口的限位,内压口移动的过程中抵球将会抵在受力球上,让衔接部位有一定的起伏,对其外侧的抵触进行反推,让外环在抵触时,有一个最大范围的力,能够在对物体进行吊动时,将其反向钩固定住。
