Abstract

The utility model discloses an auto-release load hoisting hook which is characterized in that the body of the hook is provided with an electromagnetic device for controlling a sling jaw to auto-release a load. When a weight is hoisted, the sling jaw is locked by a block to cause the sling jaw and the suspender to form an L shape; when the weight is released, the weight only needs to be put onto the destination; the sling jaw releases and touches the ground; then the power of an electromagnetic coil is switched on; the block is sucked up and simultaneously the whole sling jaw is hoisted; then the sling jaw auto-releases the load. The utility model has the advantages of simple structure, convenient operation, high reliability and low cost.

Description

Auto-release hoisting hook

The utility model relates to a kind of load hook that has improved, particularly a kind of load hook that can the autospasy unloaded.

Usually the suspension hook of hoisting heavy employing need manually be freed the steel rope that binds weight after putting weight, and is both inconvenient, also dangerous.People had done some improvement to load hook afterwards, on whole suspension hook, designed suspension bracket automatic release mechanism (US Patent 4251099), reach though can free the steel rope that binds weight automatically and to unload the purpose of taking off weight voluntarily, but be that its structure is more numerous on the one hand, and when hanging weight, still need manual operation, on the other hand, in the actual production operation, the cable wire wearing and tearing of hanging weight are too big, and it is complete with the passing of time to feel unwell.

The purpose of this utility model just provides a kind of cargo hook gear that has improved, and it can lift by crane easily and safely and unload and take off weight.

According to the suspension hook that the utility model proposed, mainly comprise and hang pawl, anchor shaft, arm, crossbeam, magnet coil, moving iron and the block inhaled is characterized in that the said pawl that hangs can pass through the control realization of block from sagging by electromagnet.

Below in conjunction with accompanying drawing enforcement of the present utility model is specified.

Accompanying drawing 1 is the longitudinal sectional drawing of the utility model concrete structure.

Accompanying drawing 2 is left views of accompanying drawing 1, has reflected global shape of the present utility model.

The utility model is achieved in that with reference to accompanying drawing 1 and accompanying drawing 2, before the lifting weight, at first make with anchor shaft 6 the hang pawl 7 that be long arc shape sagging and return to as shown in Figure 1 position for fixing pivot point freely hangs, allow and hang pawl 7 and 11 one-tenth of arms " L " shape, this moment, block 5 just relied on deadweight and voluntarily along hole slot 8 and along arc section 9 slips of hanging pawl 7 one ends and sagging, magnet coil 2 is in off-position, suspension hook just can the handling weight like this, unloading when taking off weight, only need the weight of handling is docked at the destination, and with this suspension hook pine to ground, the lower edge (arc convex part) of promptly hanging pawl 7 contacts with ground, make the contact portion of hanging pawl 7 and block 5 produce the gap, at this moment with magnet coil 2 energized (220V), the fixing just carrying magnetic of iron 1 of inhaling, inhale iron 3 and pick up with moving to top, upwards pick up together along hole slot 8 by the moving metal trough nut 4 band blocks 5 of inhaling simultaneously, thereafter will put in order suspension hook by crossbeam 10 and arm 11 promotes, just break away from load gradually according to anchor shaft 6 generation rotations so hang pawl 7, hang pawl 7 at last and be in free hang, cut off the power supply of magnet coil 2 this moment, cause block 5 freely to stop to drop on the arc section 9 that hangs pawl 7, prepare against subjob down.

Above-mentioned implementation procedure is that two groups of suspension hooks of the utility model carry out (seeing shown in the accompanying drawing 2) simultaneously.

In sum, the utility model has the advantage of that it is simple in structure, low cost of manufacture has wide range of applications, safety easy to loading and unloading. Be particularly useful for handling strip weight, such as steel, timber and other material of long strip type, and when handling, can tie up extension without cable wire, not only save producing cost but also can raise the efficiency.

Claims

From shirk load hook, mainly comprise arm [11], hang pawl [7], magnet coil [2], moving iron [3], block [5], the anchor shaft [6] inhaled, it is characterized in that hanging pawl [7] and be the long arc shape, and arc section [9] block [5] that an end has one section confession block [5] to slide is used for pinning and hangs pawl [7], make and hang pawl [7] and become " L " shape with arm [11], other is equipped with the magnet coil [2] that control block [5] rises and falls, this suspension hook is to hang pawl mechanism by two groups, and being formed by connecting by a crossbeam [10] is a whole suspension hook.
