Abstract

The utility model relates to a hanging tool of flat plate type, in particular to a combined hanging tool used for flat hanging and turning over of a hot pressboard. In the past, we need to drill hanging technology-related screw holes on two sides of the hot pressboard and then hang the hot pressboard directly with cable wire, which sways to-and-fro, thereby it is very dangerous and apt to make damages to processed surfaces. The technical plan of the utility model has changed the original hanging of soft cable wire into hanging with steel frame structure, which comprises an arch board, a beam, a flat hanging board, a hanging hook, a turning board and a channel steel. With a frame structure, the hanging hole centre of the turning board being lower than the gravity center of the hot pressboard, and the arc board structure, the utility model can be used to easily carry out flat hanging and turning over of a hot pressboard. The utility model is characterized in that the structure of the tool is simple, the model is easy to be manufactured, the versatility is good; the model can be used smoothly, safely and reliably, can prevent the hot pressboard from disforming under press, and the utility model can also prevent from damaging the processed working surface.

Description

Heating platen is put down and is hung and stand up the combined hanging instrument

Technical field

The utility model relates to a kind of lifting device of plate class, particularly relates to a kind of flat combined hanging instrument that hangs and stand up of continuous press heating platen that is used for.

Background technology

In the manufacturing process of Wood-based Panel Production equipment, the flat method of hanging and standing up for the continuous press heating platen, always be to adopt steel rope to hold four boatswain chairs that are fixed on the heating platen both sides to put down and hang, stand up the boatswain chair of then holding a side, winch to and dangle when vertical, also will go to add an external force this moment overturns it on request, very dangerous, though this method is simple, must stamp the hoisting screw in the both sides of heating platen, and in hoisting process the surface of heating platen sensitive for damages.In continuous press, the precision of heating platen and surface quality require very high, and both sides do not allow to beat screw yet, so prior art is inapplicable aborning.

Summary of the invention:

In order to solve the deficiencies in the prior art, the purpose of this utility model just provides the flat lifting device that hangs and stand up of a kind of brand new heating platen, and heating platen can steadily be lifted by crane, and is not hit when standing up, and surface quality is unaffected.The technical solution of the utility model is that the original soft steel wire rope hook of change is the suspension hook of the framed structure of rigidity, causes the hanging piece heating platen to tilt flat can avoiding when hanging because of each suspension hook unbalance stress of steel rope, damages in easy deformation and surface.The utility model is to realize by following concrete technical measures: a kind of heating platen is put down and is hung and stand up the combined hanging instrument, it is characterized in that it mainly comprises arc plate 1, crossbeam 2, flat boatswain chair 3, suspension hook 4, turn over boatswain chair 5 and channel-section steel 6 compositions, wherein: the suspension hook 4 that plate iron is made is T-shaped weld assembly, per two suspension hooks 4 are installed in the both sides, below of crossbeam 2 relatively, its mouth of hook is inside, the inboard of the top board on suspension hook 4 tops and the back plate connections of crossbeam 2 is processed with bolt mounting holes, and the bolt mounting holes in the outside of the top board on suspension hook 4 tops and the back plate connections of crossbeam 2 is split into long slot bore; In that two channel-section steels 6 of bolt together between two crossbeams 4 of suspension hook 4 are housed, form a framed structure, four flat boatswain chairs 3 are installed on four angles of this framed structure; Side end at two crossbeams 2 is installed two arc plates 1 that radius is 300mm; Turn over boatswain chair 5 what the end side of two crossbeams 2 was installed two downward bendings, the center of its hole for hoist must be lower than the center-of-gravity position of heating platen, generally low 5-10mm.Above-mentioned each member is shaped steel or plate iron weldment, bolt together again.The using method of the utility model lifting device is: need do not hung the skill bolt hole of doing manual work on the heating platen N, when lifting heating platen N, unload the bolt of four suspension hooks 4 and crossbeam 2 bonded assembly inboards earlier, the bolt that unclamps the outside makes four suspension hooks 4 slide laterally and do not need to unload suspension hook 4 along the long slot bore under the crossbeam, after making heating platen N snap in suspension hook 4, between the thickness place of heating platen N and suspension hook 4, pad with cushion block, screw the bolt in suspension hook 4 outside long slot bores again, make the firm clamping of heating platen in lifting device, with sling four flat boatswain chairs 3 on the framework that constitutes by crossbeam 2 and channel-section steel 6 of steel rope, flat hanging in the heating platen N process steadily, safety, reliably.When heating platen N turnover hoisting, steel rope two holes for hoist that turn in the boatswain chair 5 of two crossbeams, 2 one sides of slinging, because the center of this hole for hoist is than the low S of heating platen N center-of-gravity position, so just, can be in the process of standing up of slinging when steel rope is pulled to the upright position the existing trend of swinging to the another side upset of heating platen N, need when winching to the upright position, not apply the dangerous measure that external force makes it to overturn to other direction, because at the opposite side of two crossbeams 2 arc plate 1 that two radiuses are installed is 300mm, so when winching to vertical and overturning, lifting device can steadily roll along arc surface, has avoided being clashed in switching process.In addition, the suspension hook mouth of four suspension hooks 4 all is inside installation, flat hang and stand up Shi Buhui occur suspension hook 4 outwards skid off and make that heating platen N drops may.

Advantage of the present utility model is artificial pulling in the continuous press manufacturing process, for heating platen so not only heavily but also the processing of big workpiece, no matter be to put down to hang, still stand up, adopt that lifting device of the present utility model can both reach steadily, safety, reliable, can prevent that heating platen deformation in compression and machined surface from damaging, guarantee technological requirement and the crudy of work piece heating platen N, and the utility model is simple in structure, easy to manufacture, commonality is good, do not damage work piece.
