Problems solved by technology

[0002] In modern construction production, there are more and more large-tonnage hoisting, and the requirements for hoisting connectors are also getting higher and higher. It is very inconvenient and time-consuming and labor-intensive to close the opening, and cause the adverse consequences of low work efficiency. For this, it is very important to develop a self-locking lifting hook with simple structure, low operating cost, safety, reliability and good use effect. Significance

Embodiment 1

[0015] Such as figure 1 As shown, a self-locking hook of a crane, the hook main frame 1 is provided with a tangential first arc-shaped elastic piece 2 and a second arc-shaped elastic piece 4, and the first arc-shaped elastic piece One end of the elastic sheet 2 is connected to one side of the hook main frame 1, and a barb 3 protrudes outward from the other end. Preferably, the barb 3 is long or herringbone; in this embodiment In the example, the barb 3 is a long strip that is tilted upward; one end of the second arc-shaped elastic piece 4 is connected to the other side of the hook main frame 1, and the second arc-shaped elastic piece 4 The other end is provided with a groove matching the barb 3, and the first arc-shaped elastic sheet 2 and the second arc-shaped elastic sheet 4 are respectively provided with a baffle plate 7 connected to the hook main frame 1 at the corresponding top. When the first arc-shaped elastic sheet 2 and the second arc-shaped elastic sheet 4 are in co...

Embodiment 2

[0019] It is the same as Embodiment 1, except that the slider 5 is detachably connected to the upper end of the vertical slide rail, such as pinned or bolted. When it is necessary to remove the inner rope of the hook main frame 1, disassemble the slider 5 from the vertical slide rail, manually slide the slider 5 to the bottom of the slide rail, and separate the barb 3 from the groove. in between.

Abstract

The invention discloses a self-locking lifting hook of a crane. A first circular arc-shaped elastic piece and a second circular arc-shaped elastic piece tangent to each other are arranged in a liftinghook main frame; the end part of one end of the first circular arc-shaped elastic piece is connected with one side of the lifting hook main frame; the end part of the other end of the first circulararc-shaped elastic piece is protruded outwards so as to be provided with an overhead hook; the end part of one end of the second circular arc-shaped elastic piece is connected with the other side of the lifting hook main frame; a groove matched with the overhead hook is formed in the end part of the other end of the second circular arc-shaped elastic piece; and when the first circular arc-shaped elastic piece is abutted against the second circular arc-shaped elastic piece, the overhead hook of the first circular arc-shaped elastic piece stretches into the groove of the second circular arc-shaped elastic piece. The self-locking lifting hook of the crane provided by the invention is simple in structure, capable of being self-locked through the matching of the overhead hook on one circular arc-shaped elastic piece and the groove in the other circular arc-shaped elastic piece tangent to the first circular arc-shaped elastic piece, and good in use effect.

Description

technical field [0001] The invention specifically relates to a self-locking hook of a crane. Background technique [0002] In modern construction production, there are more and more large-tonnage hoistings, and the requirements for hoisting connectors are getting higher and higher. It is very inconvenient and time-consuming and labor-intensive to close the opening, and cause the adverse consequences of low work efficiency. For this, it is very important to develop a self-locking lifting hook with simple structure, low operating cost, safety, reliability and good use effect. Significance. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a self-locking hook with simple structure, low operating cost, safety and reliability, and good use effect. [0004] The solution adopted in the present invention is as follows, a self-locking hook of a crane, the main frame of the hook is provided with a ta...
