Problems solved by technology

[0004] The inventor believes that when the hooks used by the existing cranes need to drop heavy objects from high places, people often need to go up to the high places to open the pins and manually unhook them. However, for example, when assembling iron towers, it is necessary to lift When it comes to the legs of the turret, the tower leg is about 6 meters high. The tower leg of the turret is generally a very long angle iron, and people cannot climb up to open the pin manually.

Embodiment 1

[0037] Firstly, this embodiment discloses an automatic decoupling device, which includes a plurality of perforated limiters fixedly connected to the hook body 10, and a flexible rope-like member passing through the plurality of limiters;

[0038] The arrangement shape of a plurality of position-limiting parts is adapted to the shape of the hook body 10, and the position-limiting part at the first position in the plurality of position-limiting parts is fixed to the movable part 11 of the suspension hook body 10; When a force is applied in a direction away from the first position limiting member, the flexible rope-like member can pull the movable part 11 of the hook body 10 .

[0039] It can be understood that, in this embodiment, there are 6 limiters, and the 6 limiters are distributed on the two sides of the hook body 10 , and the flexible rope-like member is a steel wire rope 3 .

[0040] Among the 6 limiters, there are 4 limiters located outside the first position. It should...

Embodiment 2

[0052] This embodiment discloses an automatic unhooking hook, which includes a hook body 10 and an automatic unhooking device connected to the hook body 10 .

[0053] What needs to be explained in detail here is that the hook body 10 in this embodiment includes a hoop, a hook-like body 12 and a movable part 11, the hook-like body 12 is fixedly connected to the hoop, and the end of the movable part 11 is hinged and movable. One end of the movable part 11 has an elastic part between the movable part 11 and the hook 12. The movable part 11 is rod-shaped. Therefore, the movable part 11 can rotate around its hinge point reciprocatingly with its hinge point as a fulcrum.

[0054] The automatic decoupling device in this embodiment includes four stoppers with perforations that are fixedly connected to both sides of the hook pile body of the hook body 10, and two stoppers with perforations that are fixedly connected to the movable part 11 of the hook body 10. The limiting parts and the...

Embodiment 3

[0058] This embodiment discloses an automatic decoupling method, which adopts the automatic decoupling device as described in embodiment 1, or the automatic decoupling hook described in embodiment 2, and applies a force far away from the limit piece located at the first position to the flexible rope-like member. Direction of force, the flexible rope can pull the movable part 11 of the hook body 10 .

[0059] It also includes an automatic dragging mechanism. The automatic dragging mechanism includes a power source, a controller and a distance sensor 5 installed on the hook body 10. When the distance sensor 5 detects the distance set by the hook sensor from the ground, the power is activated. source to apply a force to the flexible cord in a direction away from the stopper at the first position.

[0060] In this embodiment, the power source is a stepper motor 5 that is easy to control, and the power source can also be selected from various forms of power sources such as pneumati...

Abstract

The invention discloses an automatic unhooking device, a lifting hook and a method. The automatic unhooking device comprises a plurality of limiting parts which are fixedly connected to a lifting hookbody and are provided with through holes, and a flexible rope-shaped part which penetrates through the plurality of limiting parts, the arrangement shape of the limiting parts is matched with the shape of the lifting hook body; the limiting part positioned at the head position in the plurality of limiting parts is fixed on a movable part of the lifting hook body; and when force away from the direction of the limiting part located at the head position is applied to the flexible rope-shaped part, the flexible rope-shaped part can drag the movable part of the lifting hook body. According to theautomatic unhooking device, the lifting hook and the method, parts capable of facilitating construction are additionally arranged on an existing lifting hook, and the existing lifting hook is improvedin a targeted mode, so that treating high-position parts which are difficult to install is conveniently carried out in the construction process, and construction is further facilitated.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to an automatic decoupling device, a hook and a method. Background technique [0002] Crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of the crane is the unified title of lifting machinery. Usually called cranes are mainly car cranes, crawler cranes and tire cranes. The usefulness of the crane lies in hoisting equipment, emergency rescue, lifting, machinery, and rescue. [0003] The executive mechanism of the crane often uses a hook. The general structure of the existing hook is to add a mechanism that can be switched on the main body of the hook. This single hook is simple to manufacture and easy to use, but the force is not good. For workplaces with a lifting capacity of less than 80 tons; when the lifting capacity is large, double hooks with symmetrical forces are often used...
