Embodiment 1

[0023] Embodiment 1: The present invention is described in further detail below. like figure 1 , 2 as shown,

[0024] A mechanical hook release device, wherein:

[0025] The head of the hook 1 is provided with a pin hole, the head of the elastic stop pin 2 protrudes from the pin hole, the root of the hook 1 is hinged with the shell 8, the hook 1 can rotate around the shell 8, and the head of the catch 3 is caught by the head of the stop pin 2 Hold, the root of the baffle 3 is pinned to the root of the hook 1, and a baffle spring 4 is provided between the root of the baffle 3 near the middle and the root of the hook 1; the unlocking device 7 is installed on the shell 8, and the tube head of the unlocking device 7 The part is connected with one end of the stay rope 5, the stay rope 5 passes through the hook 1 and connects with the root of the stop pin 2, and the bush of the unlocking device 7 is provided with a latch 6;

[0026] Touch the latch 6, and after the unlocking dev...

Embodiment 2

[0035] The actuation method of the latch 6 is that the hook is actuated naturally when the hanging heavy object falls to the ground and rotates around the casing.

[0036] The latch 6 is inserted into the unlocking device 7, the unlocking device 7 is locked with a tool, the stay cord 5 is in a relaxed state, the hanging object 9 is hung on the hook 1, and the catch 3 is in a closed state, as figure 1 Shown; After the hanging weight 9 falls to the ground (arrives at the destination), the hook 1 is in a loose state, and when the hook 1 rotates a certain angle around the phase hinge point, the latch 6 is touched, the unlocking device 7 works, and the stay rope 5 is tightened. The pulling force of unblanking device 7 is greater than the weight of hanging object 9 ropes, and catch 3 is opened, and stay cord 5 breaks away from hanging object 9 ropes and hook 1, as attached figure 2 shown.

Abstract

The invention provides a mechanical type hook release device and belongs to the field of machinery. According to the technical scheme, the head of a hook (1) is provided with a pin hole, the head of an elastic stop pin (2) extends out from the pin hole, and the root of the hook (1) is hinged to a shell (8); the head of a stop plate (3) is clamped by the head of the stop pin (2), the root of the stop plate (3) is hinged to the root of the hook (1), and a stop plate spring (4) is arranged between the position, close to the middle, of the root of the stop plate (3) and the root of the hook (1); and an unlocking device (7) is mounted on the shell (8), the pipe head of the unlocking device (7) is connected with one end of a pull rope (5), the pull rope (5) penetrates through the hook (1) and is connected with the root of the stop pin (2), and a bolt (6) is arranged on a bushing of the unlocking device (7). The mechanical type hook release device is low in cost, is simple and compact in structure, can be repeatedly used and is long in service life.

Description

technical field [0001] The invention belongs to the mechanical field. Background technique [0002] At present, there are two main types of devices for hook detachment at home and abroad: manual type and explosive type: [0003] 1. Manual type; manual disengagement means that after the heavy object is suspended (reaching the destination), the suspended heavy object is removed from the hook by a person. It is generally used for crane (gantry crane) hoisting, and the work efficiency is low. [0004] 2. Explosive type: At present, the explosive type is generally used in helicopter hanging. When the helicopter lifts the hanging object to the destination, if it is inconvenient to use the manual disengagement method, the pilot generally uses the pilot to start the explosive bolt to connect the hook. If the structure is damaged, release the suspended objects. Contents of the invention [0005] The purpose of the present invention is: [0006] Design a mechanical hook detachmen...
