Problems solved by technology

[0004] However, with regard to the current traditional load spreader, when lifting heavy objects, the center of the sling is sometimes not at the inner bottom end of the hook body, resulting in rigid friction between the sling and the inner bottom end of the hook body when the heavy object is hoisted. Moreover, the hook body sometimes rotates with the hoisted heavy object, which affects the safety of hoisting. Secondly, after the hoisted heavy object falls to the ground, it is necessary to drop the hook to a very low level to remove the sling, which affects the hoisting efficiency.

Embodiment

[0034] Example: please refer to Figure 1 to Figure 8 :

[0035] The present invention provides a load hanging device for a mechanical lifting tower, including: a hook body 1, a clamping plate 1071, a protective sleeve 2, a balance sleeve 3 and a traction member 4;

[0036] A tongue blocking member 101 is rotatably installed on the hook body 1, and the tongue blocking member 101 is rotated and installed on the upper end of the hanging hook body 1 through a rotating shaft, and a torsion spring is installed on the rotating shaft, and the lower hook end of the hanging hook body 1 is provided with a lower screw. There are two sets of opposite side support members 103 installed. The two side walls of the hook body 1 are also provided with guide tubes 105, and the guide tubes 105 are respectively inserted with pull ropes 106. One end of the pull rope 106 is connected to the stopper. The bottom side of the outer end of the tongue piece 101 is connected to the bottom side, and the ot...

Abstract

The invention provides a load hanging device for a mechanical lifting tower crane, which relates to the technical field of load hangers, and comprises a lifting hook body, a clamping plate, a protective sleeve, a balance sleeve and a traction piece, two sets of opposite side supporting pieces are installed at the lower hook end of the lifting hook body, one end of a pull rope is connected with the bottom side of the outer end of a tongue blocking piece, the other end of the pull rope is connected with the bottom end of a side connecting frame on the side supporting pieces, and the top end of the lifting hook body is further connected with a top connecting rod which is inserted in the middle of a protective sleeve in a penetrating mode and clamped through two sets of clamping plates. The balance sleeve is sleeved at the middle end of the top connecting rod through the key shaft hole, the lower end of the traction piece is of an inverted T-shaped structure and is provided with an insertion cavity, and the top connecting rod penetrates into the insertion cavity through the inner insertion hole and is clamped through a nut. And when the heavy object falls to the ground, the tongue blocking piece is automatically separated from the opening end of the lifting hook body, so that the problems that when the heavy object is lifted, the lifting rope is in hard friction with the bottom end of the inner side of the lifting hook body, the lifting hook body sometimes rotates along with the lifted heavy object, and the lifting safety is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of load hangers, in particular to a load hanger for a mechanical lifting tower. Background technique [0002] As one of the key components in the mechanical pendant, the load hook is widely used in various loading and unloading and handling work. [0003] For example, in the patent with the application number: 202111101124.5, a sling with a hook for lifting a crane is disclosed. The present invention provides a sling with a hook for lifting a crane, which relates to the technical field of slings to solve the problem of In the process of hoisting and transporting light cargo with large volume and high height, the cargo itself is prone to shaking, and the large shaking can easily cause the bundled cargo to be scattered. Decoupling increases the problem of risk factors for operators, including the main body of the spreader; the upper end of the main body of the spreader is fixedly installed with a pulling head...
