Unhooking device

Abstract

The invention relates to an unhooking device. The unhooking device comprises a fixed piece and a hook; the hook comprises a first half hook and a second half hook; at least the first half hook is hinged to the fixed piece; the fixed piece is provided with a vertically arranged guide rail which is provided with an adjusting piece; the adjusting piece is connected with the first half hook through afirst connection rod; the two ends of the first connection rod are hinged to the upper end of the first half hook and the adjusting piece correspondingly; when the adjusting piece moves in the vertical direction of the guide rail, the first half hook rotates along a hinging point on the fixed piece and achieves opening and closing of a hoisting hole; and the adjusting piece is fixed to the presetposition of the guide rail through a positioning piece. The unhooking device is simple in structure, small in size and low in cost, the lever principle is fully utilized to achieve carrying of the hook and unhooking unloading, labor is saved, reliability is high, effects are direct, the unhooking effect is good, the instant unhooking opening effect can be achieved, action delaying is avoided, unloading and falling positions of carried articles are accurate, high-speed unhooking releasing can be achieved, and the unhooking device is especially suitable for carried articles with large load and hoisting of goods carried at high speed.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a decoupling device. Background technique [0002] In the current field of lifting equipment, the commonly used equipment includes hooks, steel wire cable buckles, etc. The above-mentioned lifting equipment usually uses one person to connect the packaged goods with the hook of the crane using steel wire cables or nylon cables, and the crane lifts and transfers the goods. After arriving at the designated transportation point, another person will untie the cable, thus completing a lifting cycle. The lifting efficiency of the above-mentioned method is low. During the lifting process of the goods, a special person is required to untie the cable. When unclasping by manual work, the risk of instability of the goods is relatively high, and the operation efficiency is low. On the other hand, the use of existing hooks, wire cables to transfer goods or installation ...

Problems solved by technology

The lifting efficiency of the above method is low. During the lifting process of the goods, a special person is required to untie the cable. When using manual work to untwist, the risk of instability of the goods is high, and the operation efficiency is low.

On the other hand, the use of existing hooks, wire cables to transfer goods or installation components needs to be placed slowly and unbuckled only when the safety of the unclamping personnel is ensured. The safety factor is greatly affected by the limited vision of the crane operator.

[0003] In order to solve the above technical problems, in the prior art, technicians have designed automatic uncoupling devices, which are commonly used in the following three types. The first one is to use a wire rope to pull and release. This method cannot meet the requirements of release at any position and at any time, and There is a large error in the release point, and there is no automatic control capability; the second is to use the cylinder movement to drive the decoupling release. This method is relatively safe and reliable, but due to the delay caused by the push rod or cylinder action, the effect of instantaneous decoupling cannot be achieved; The third method is to use explosive bolts. This method decouples quickly, but cannot be reused, and it is difficult to achieve synchronous control of multiple explosive bolts during the decoupling process.
