Abstract

The utility model relates to a self-unloading lifting sling comprising a plurality of adjacent sling components that are articulated with each other. The adjacent sling component comprises a chain plate and a bolt, and the chain plate is articulated with the adjacent chain plate through the bolt. The upper surface of the chain plate is contacted with the goods being hung, and the lower surface of the chain plate is contacted with the hanging surface. When in use, after the goods are dropped, the only need is to untie one end of the lifting sling, and the other end can be directly extracted and self-unloaded by manpower, lifting machine, forklift truck or other hoisting equipment without damaging the goods being hung or the package and hanging face thereof. The utility model needs not secondary transportation, has convenient self-loading ability, fast speed and high efficiency, saves manpower and decreases labor intensity.

Description

Self-unloading lifting chain sling

Technical field

The utility model relates to a kind of equipment of reusing, and is a kind of self-unloading lifting chain sling specifically.

Background technique

General lifting is single-piece or some hanging objects to be positioned over the back falls to hanging after moving to desired location by Hoisting Machineries such as loop wheel machine or fork trucks above the suspender belt.Except that shipping container or special-purpose case, chain sling (generally being made by metallic material), suspender belt (generally being made by nonmetallic material such as nylon) or cat net (claim again to close rope, made by nonmetallic material such as nylon usually) are generally used in existing lifting.Often need make rehandling after falling to hanging, be about to hanging object, move desired location to artificial or machinery in suspender belt or the cat net and could take out chain sling, suspender belt or cat net to reuse from chain sling.For example, during article such as packed grain, feed, cement, chemical fertilizer, agricultural chemicals and the chemical industry of lifting at present usually, building materials, generally be that some bags are placed on chain sling, suspender belt or the cat net (), deliver to fall to hanging after the desired location again sacked goods by loop wheel machine or fork truck again, could take out chain sling, suspender belt or cat net to reuse by manually moving.Chain sling, suspender belt or cat net are pushed down because of hanging object, can not directly extract out to reach self-unloading, also can damage the packing of hanging object or hanging object and fall to hanging the surface even extract out by force.Therefore the shortcoming of prior art is that speed is slow, and consumption is artificial, and labor intensity causes the cost height greatly, and efficient is low etc.

Summary of the invention

The utility model is in order to overcome the deficiency that above prior art exists, and provides that a kind of self-unloading is convenient, efficient is high, saved manpower, do not damage hanging object and fall to hanging the self-unloading lifting chain sling on surface.

The purpose of this utility model realizes by following technological scheme: self-unloading lifting chain sling, it is characterized in that: described self-unloading lifting chain sling is by adjacent hinged the forming of a plurality of chain sling assemblies, described chain sling assembly comprises carrier bar and latch, be hinged by latch between described arbitrary carrier bar and the adjacent carrier bar, the upper surface of described carrier bar contacts with hanging object, the lower surface of carrier bar with fall to hanging the surface contact.

Described carrier bar is a fork-shaped, and the fork handle end of arbitrary carrier bar is hinged by the prong end rear end of latch and adjacent carrier bar.

The flakiness ratio of described carrier bar is between 1.2: 1 to 100: 1.

The upper and lower surface of described carrier bar is provided with striped.

The all or part of surface of the upper surface of described carrier bar is an arc surface.

The all or part of surface of the lower surface of described carrier bar is an arc surface.

The all or part of surface of the upper and lower surface of described carrier bar is an arc surface.

The fork handle end of described carrier bar is hinged by the prong end front end of second latch and carrier bar self.

The utility model has following advantage with respect to prior art: the self-unloading lifting chain sling that the utility model technology provides, chain sling is after falling to hanging, only need untie an end of chain sling, the other end is directly extracted out by manpower, loop wheel machine, fork truck or other crane gear and is reached self-unloading.Because carrier bar is a flat, smooth surface, upper surface contacts with hanging object, lower surface with fall to hanging the surface contact, reduce the frictional force between these two interfaces largely, chain sling can be extracted out easily and be unlikely the packing of damaging hanging object or hanging object and fall to hanging the surface.This self-unloading chain sling need not rehandling, self-unloading is convenient, speed is fast, efficient is high, save manpower, reduce labor intensity.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment 1:

A kind of self-unloading hoisting hook chain component as depicted in figs. 1 and 2, described self-unloading lifting chain sling is by adjacent hinged the forming of a plurality of chain sling assemblies, described chain sling assembly comprises fork-shaped carrier bar 1 and latch 2, the fork handle end 10 of carrier bar 1 is hinged by prong end 11 rear ends 110 of latch 2 with adjacent carrier bar, the upper and lower surface of carrier bar 1 in the position that is hinged is arc surface, the upper surface of carrier bar 1 contacts with hanging object, lower surface with fall to hanging the surface contact.The flakiness ratio of carrier bar 1 is 10: 1, and the upper and lower surface of carrier bar 1 is provided with striped.

Chain sling only need be untied an end of chain sling after falling to hanging, the other end is directly extracted out by manpower, loop wheel machine, fork truck or other crane gear and reached self-unloading.Because carrier bar is a flat, smooth surface, upper surface contacts with hanging object, lower surface with fall to hanging the surface contact, reduce the frictional force between these two interfaces largely, chain sling can be extracted out easily and be unlikely the packing of damaging hanging object or hanging object and fall to hanging the surface.This self-unloading lifting chain sling can be made by tension, metal or other material wear-resisting, light weight.

Embodiment 2:

Another kind of self-unloading lifting chain sling as shown in Figure 3 and Figure 4, described self-unloading lifting chain sling is by adjacent hinged the forming of a plurality of chain sling assemblies, described chain sling assembly comprises fork-shaped carrier bar 1 and latch 2, the fork handle end 10 of carrier bar 1 is hinged by latch 2 prong end 11 rear ends 110 with adjacent carrier bar, and the fork handle end 10 of carrier bar 1 links mutually by prong end 11 front ends 111 of second latch 20 and carrier bar 1 self.

Above-mentioned embodiment is a preferred embodiment of the present utility model; can not limit claim of the present utility model; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection domain of the present utility model.
