Abstract

The invention discloses a lifting point device for an embedded sleeve. A traction wheel is rotatably installed on a lifting point device body to achieve adjustment of the large lifting height, then a rotary connecting block is rotatably installed at the lower end of the lifting point device body, and a rotary connecting sleeve is rotatably connected to the lower end of the rotary connecting block. The other end of the rotary connecting sleeve is connected with one end of a lifting hook through a rotary connecting shaft, one end of the rotary connecting shaft is provided with external threads, the other end of the rotary connecting sleeve is provided with internal threads, one end of the rotary connecting shaft is connected with the other end of the rotary connecting sleeve through threads, and the other end of the rotary connecting shaft is fixedly connected with one end of the lifting hook. The rotary connecting sleeve and the rotating connecting shaft are connected through the threads to form a structure capable of extending and retracting the lifting hook in a short distance, when a heavy object is lifted, it can be guaranteed that the lifting hook does not rotate, extending and retracting are achieved through the rotary connecting sleeve, the structure is simple, installation is convenient, and the height adjusting precision of a lifting point is greatly improved; and the rotary connecting block can also rotate axially, and a multidirectional rotation angle is provided.

Description

technical field [0001] The invention relates to the technical field of pre-buried casing hoisting, in particular to a lifting point device for a pre-buried casing. Background technique [0002] The pre-buried casing is for the pipe to pass through the holes reserved for brick walls, concrete beams, concrete walls and other components. It is suitable for civil air defense, underground engineering, chemical industry, steel, tap water, sewage treatment and other pipelines that require strict waterproofing through walls. When the heavy casing is pre-buried, it needs to be hoisted by a crane. The crane is generally connected to the casing through a lifting point. The lifting point is the connection between the hoisting object and the hoisted object during the hoisting operation. . When the lifting point device is in use, due to the short distance between the lifting point and the casing, it is inconvenient to adjust the height through a crane. Falling on the ground will cause d...
