Abstract

The utility model relates to a steel tube lifting hook which comprises a hook body (1) and a locking clamping block (2). A bolt hole (5) is formed in the end portion of one side of the hook body (1). A bolt hole (5) is also formed in the locking clamping block (2). A bolt (3) penetrates through the bolt hole (5) in the hook body (1) and the bolt hole (5) in the locking clamping block (2) to enable the hook body (1) and the locking clamping block (2) to be connected together. At least one part of the locking clamping block (2) is located inside the hook body (1). The locking clamping block (2) swings around the bolt hole (5). The steel tube lifting hook has the advantages that a steel tube can be automatically locked through the locking clamping block in the lifting process, the steel tube is safely transported and can not be disengaged, and the steel tube lifting hook is the same as a common lifting hook in the appearance. When upward pulling force is exerted on the steel tube lifting hook, the internally-arranged locking clamping block will extend outwards to tightly clamp the steel tube, the larger the exerted upward force is, the larger the force for clamping the steel tube is, therefore, transport is safely carried out, and use is conveniently achieved.

Description

Steel pipe lifting hook
Technical field
The utility model relates to lifting, the transport field of steel pipe, and particularly a kind of hanging apparatus of application in steel pipe's production and transportation, be specially steel pipe lifting hook.
Background technology
In the steel pipe's production process, steel pipe transmission is modal working link, particularly finishing procedure, and the transportation between each equipment is to be undertaken by lifting substantially.The method of lifting is a lot, useful suspender belt, useful iron chains, useful holding device, useful suspension hook, in order to meet the product handling of the various shapes of workshop, all size, most workshop all standby multiple hanging is used device.The handling of bassoon generally adopts the mode of suspension hook, but, because steel pipe is long, during the suspension hook improper use, especially easily landing, cause equipment and personal safety accident.Suspension hook commonly used is all generally open type, and some originating firms are in order to increase safety factor, at the opening part of suspension hook, is provided with block, but block is very easy to damage, and substantially performs practically no function.
Summary of the invention
The purpose of this utility model is to solve existing suspension hook can not effectively pin the problem of steel pipe, and designs a kind of steel pipe lifting hook with the locking fixture block, and it can be applied to the Product transport in steel pipe's production workshop.In transportation, suspension hook hangs over the two ends of steel pipe, and overhead traveling crane is in upwards pulling the suspension hook process, and suspension hook fixture block auto-extending locking steel pipe two ends, make transportation safety, convenience.
In order to complete goal of the invention of the present utility model, the utility model by the following technical solutions:
A kind of steel pipe lifting hook of the present utility model, this suspension hook comprises: hook and locking fixture block, wherein: there is a bolt hole end in hook one side, on the locking fixture block, a bolt hole is also arranged, bolt is through the bolt hole on hook and locking fixture block, to link up with and lock fixture block and link together, and at least lock the part of fixture block in hook, the locking fixture block swings around above-mentioned bolt hole;
A kind of steel pipe lifting hook of the present utility model, wherein: the end of described locking fixture block has the lanyard hole;
A kind of steel pipe lifting hook of the present utility model, wherein: there is sawtooth on the surface of the locking fixture block in hook.
Steel pipe has auto lock fixture block 2 in the handling process, and steel pipe transmission safety can not come off.The design of steel pipe lifting hook is very ingenious, and when steel pipe lifting hook belongs to relaxation state, locking fixture block 2 and hook 1 be with being integrated, locking fixture block 2 be built in hook 1 in, from the appearance, steel pipe lifting hook of the present utility model and suspension hook commonly used are without any difference.When steel pipe lifting hook is subject to upper pulling force, the built-in locking fixture block of the utility model steel pipe lifting hook is protruding, tightly block steel pipe, make progress stressed larger, the dynamics of blocking steel pipe is just larger.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model steel pipe lifting hook;
The structural representation that Fig. 2 is locking fixture block in Fig. 1.
In Fig. 1 and Fig. 2, label 1 is hook; Label 2 is the locking fixture block; Label 3 is; Label 4 is bolt; Label 5 is bolt hole; Label 6 is sawtooth.
The specific embodiment
As depicted in figs. 1 and 2, steel pipe lifting hook of the present utility model comprises: link up with 1 and locking fixture block 2, there is a bolt hole 5 end in hook 1 one sides, on locking fixture block 2, a bolt hole 5 is also arranged, bolt 3, through the bolt hole 3 on hook 1 and locking fixture block 2, will be linked up with 1 and link together with locking fixture block 2, at least lock the part of fixture block 2 in hook 1, locking fixture block 2 swings around above-mentioned bolt hole 3, and its end has lanyard hole 4.There is sawtooth 6 on the surface of the locking fixture block 2 in hook 1.
Steel pipe lifting hook of the present utility model is comprised of hook 1, locking fixture block 2 and bolt 3, and locking fixture block 2 is positioned in the middle of hook 1, and after bolt 3 connects, locking fixture block 2 belongs to free state.In handling steel pipe process, after hook 1 is suspended to steel pipe, steel pipe lifting hook is subject to upper pulling force, and locking fixture block 2 be take bolt hole 5 as axle center counter-clockwise swing automatic locking steel pipe.Due to locking fixture block 2 itself, with sawtooth 6, more lock is tighter after stressed, and safe lifting is convenient, reliable.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that, without prejudice to spirit of the present utility model, the utility model can be done any type of modification.
