Description
Technical field
The utility model relates to vacuum lifting tool, particularly a kind of vacuum sucker lifting appliance for special-shaped angle section carrying.So-called special-shaped angle section refers in particular to the section bars such as shape tube that cross-sectional shape relates to equilateral right angle, shaped pile, especially comprises the section bars such as hollow square pile, solid square pile, steel tubes, angle steel.
Background technology
Vacuum lifting tool was just used in developed country in a large number as far back as mid-term in last century, and China starts from latter stage in last century to the understanding of vacuum lifting tool, was constantly developed the beginning of this century, and vacuum lifting tool has been used in all trades and professions at home at present.For the utility model relate to a kind of for special-shaped angle section and adsorb the vacuum carrying suspender of two right angle faces, a kind of hollow square pile of the below in the special-shaped angle section set forth its current situation as background.
Abroad, Japan had developed pre-stress hollow high strength concrete hollow square pile (being called for short " hollow square pile ") in 2000, " Geotechnical Engineering circle " magazine the 10th volume the 2nd is interim has reported " Japan has accounted for 40% of all piles type to the use of hollow square pile; the advantage of visible hollow square pile; the U.S. is similar Japan also; the use of hollow square pile in 2003 has reached 9000 myriametres, account for total with the stake amount 35% ".
Hollow square pile begins fast development in market at home after 2007, whole precast pile industry has been caused certain impact, the needs that it is energy-conservation, material-saving, consumption reduction meet recycling economy development, be listed in section's of building " construction industry items generalized by science and technology production generalize item in 2010 " (section of building is commented (2011) No. 1), require the engineering of conditional region, particularly country or provinces and cities' priority project should preferentially be selected this product.
Building industry has also welcome the high speed development of hollow square pile to the heavy demand of hollow square pile both at home and abroad, yet the manufacturing line of hollow square pile still adopts traditional demoulding hoisting, in " People's Republic of China's building material industry standard " (JC/T2029-2010), requiring length to adopt two to collude the method for hanging or at 2 less than the hollow square pile of 15m hangs, length adopts at 4 and hangs greater than 15m and less than hollow square pile or the spliced pile of 30m.In actual production, the mode of this lifting is that 2 or multiple spot are stressed, and square pile easily is out of shape or is produced damage, even produces fracture, and safety misadventure easily occurs.
Therefore, develop the inevitable requirement that special-shaped angle section transport hoist safely and efficiently becomes this industry development in the art.
Summary of the invention
Task of the present utility model provides a kind of special-shaped angle section vacuum sucker lifting appliance, the various problems that it has occurred in having solved and having produced, improved the service life of suspender, eliminated sucker rubber serious wear in the sucker adsorption process, easily pullled the problem that comes off, introduced new centering guiding mechanism, increased suspender horizontal positioned self-checking function, the lateral adjustments error self-compensating function of sucker, shortened operation time for positioning, increased the success ratio of operation location, reduced owing to the suspender reason causes and produced the number of times that interrupts, improved the production efficiency of special-shaped angle section (hollow square pile).
