Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, a simple hoisting tool comprises a first supporting arm 10, a second supporting arm 20, a pulling arm 30 and a connecting frame, wherein the connecting frame comprises a first connecting arm 41, a second connecting arm 42 and a third connecting arm 43 which are respectively connected at two ends of the first connecting arm 41 in a one-to-one correspondence manner, the second connecting arm 42 and the third connecting arm 43 are respectively arranged perpendicular to the first connecting arm 41, the second connecting arm 42 and the third connecting arm 43 are integrally formed into an inverted-U-shaped connecting frame, a through hole for the pulling arm 30 to pass through is formed in the first connecting arm 41, and the through hole is located at the midpoint of the length direction of the first connecting arm 41.

The connecting frame of the present embodiment is a high-strength alloy connecting frame, and the high-strength alloy refers to a conventional high-strength alloy in the market, such as a high-strength steel plate.

One end of the first support arm 10 and one end of the second support arm 20 are respectively rotatably connected to one end of the lifting arm 30, in this embodiment, a rotation shaft is integrally formed on the lifting arm 30, rotation holes are formed in one end of the first support arm 10 and one end of the second support arm 20, and the first support arm 10 and the second support arm 20 are rotatably connected to the lifting arm 30 through the cooperation of the rotation holes and the rotation shaft. The first support arm 10 and the second support arm 20 may also be rotatably coupled to the lift arm 30 by a movable bearing or other rotational coupling.

The other end of the lifting arm 30 passes through the through hole of the first connecting arm 41, and the lifting arm 30 passes through the lifting ring or the lifting hook for lifting is arranged on one end of the first connecting arm 41, and the lifting arm 30 in the embodiment is integrally connected with the lifting hook 31, so that the lifting tool can be connected with a lifting machine.

The second connecting arm 42 is slidably connected to the first support arm 10 at an end thereof remote from the first connecting arm 41, and the third connecting arm 43 is slidably connected to the second support arm 20 at an end thereof remote from the first connecting arm 41. In this embodiment, the first support arm 10 is provided with a first sliding groove 11, the second connection arm 42 is provided with a first sliding block 421, the first sliding block 421 is slidably connected in the first sliding groove 11, the second support arm 20 is provided with a second sliding groove 21, the third connection arm 43 is provided with a second sliding block 431, the second sliding block 431 is slidably connected in the second sliding groove 21, and the first support arm 10 and the second support arm 20 are slidably connected with the connection frame through the cooperation of the sliding blocks and the sliding grooves.
