Clamp unhooking device

Abstract

The invention discloses a clamp unhooking device, belonging to the technical field of the mechanical lifting and drawing equipment. The clamp unhooking device is characterized in that two clamp pieces are arranged symmetrically, one end of each clamp piece is hinged with one end of a connecting rod through a hinge, the other end of the connecting rod is connected with a slider shaft; one end of the slider shaft is connected with an opening slider; the slider shaft and the opening slider are arranged in the chutes of a first pulling plate and a second pulling plate correspondingly, mandrils are also arranged in the chutes; the other end of the slider shaft is locked in a self-locking device; the self-locking device is arranged on the lateral surface of the first pulling plate, one end of the first pulling plate and one end of the second pulling plate are connected through a hinge pin; the other end of the first pulling plate and the other end of the second pulling plate are hinged on the two sides of each clamp piece through hinges, and an unlocking rope and an unhooking rope are arranged between the pulling plates. The clamp unhooking device has simple structure, small opening force, simple and convenient operation, safe and reliable work and accurate unhooking point of fall, and can be used in the fields requiring high centering and accurate unloading position.

Description

technical field [0001] The invention relates to a hook of a lifting and pulling device, in particular to a clamp-type hook uncoupling device, which belongs to the technical field of mechanical lifting and pulling devices. Background technique [0002] The hook used to connect the load in the lifting traction mechanism is very convenient when loading, but it is more troublesome when unloading. As an improved form of the hook, the commonly used decoupling device has two basic forms: clamp type and single hook flip type. The single-hook flip-type decoupling device will generate lateral force when decoupling, causing the decoupling device to swing violently after decoupling. After the heavy object is decoupled, it is easy to cause space drift, the landing point position is inaccurate, and the neutrality is relatively poor. It is mainly used for heavy objects. Occasions where the position of the landing point is not high. Chinese patent document CN92223321.7 discloses an automat...

Problems solved by technology

The single-hook flip-type decoupling device will generate lateral force when decoupling, causing the decoupling device to swing violently after decoupling. After the heavy object is decoupled, it is easy to cause space drift, the landing point position is inaccurate, and the neutrality is relatively poor. It is mainly used for heavy objects. Occasions where the position of the landing point is not high

Chinese patent document CN92223321.7 discloses an automatic uncoupling device, which belongs to the single-hook flip type uncoupling device, which improves the sensitivity of decoupling and overcomes the space drift caused by the decoupling of heavy objects, but the safety performance is not high

Chinese patent document CN87209663 discloses a load and unloading uncoupling device, which belongs to the pincer type uncoupling device. The technical scheme is simple in structure, and it is indeed better when the requirements for the unloading position are not high, but it is inconvenient to operate and the safety performance is not good. High, it is not suitable for applications such as test detection and other fields that require high neutrality

In short, the current decoupler still has the problems of inconvenient operation, poor safety, and inaccurate unloading position.
