Abstract
The utility model relates to a lifting clasp for a heavy-duty post, which comprises two parallel bars whose one end is respectively sealed and pins. The other end of each parallel bar is respectively provided with a corresponding pin hole. One end of each pin is provided with a circular ring. The diameter of the pins is greater than that of the pin holes. The other end of each pin is provided with an anti-skid nose. The radial direction of each anti-skid nose is provided with a through hole. The lifting clasp has simple whole structure, convenient use and lower production cost, improves the man efficiency of unhooking, reduces the construction cost and is the lifting clasp with higher safety for the heavy-duty post.
Description
Technical field
The utility model belongs to the hoisting gripping member field, especially a kind of lifting snap ring of heavy pillar.
Background technology
In the installation of industrial premises structure, the decoupling device operation is normally carried out in the high-altitude behind the pillar installation in position, and the rope that so-called decoupling device operation will bundle on the pillar exactly unclamps, and is promptly consuming time dangerous again.Aerial decoupling device operation easier to tall and big heavy pillar is bigger especially, the rope cluster is adopted in heavy pillar lifting usually, rope and heavy pillar fixedly need snap ring, the structure of snap ring mainly is made of the pin of clevis eye and band screw thread at present, be inserted in the clevis eye its two terminations that have closed circle after rope bundled heavy pillar, with band screw thread pin snap ring is sealed, lifting by crane heavy pillar installation gets final product, after the installation, the key link of heavy pillar decoupling device is to open snap ring, rope is unclamped promptly finish pillar decoupling device operation element, to from clevis eye, unload down to unclamp rope with the pin of screw thread with spanner exactly and open the snap ring operation, there are the following problems for this kind structure snap ring: 1, operating personal need carry out the decoupling device operation in the long time of high-altitude stop, and safety is relatively poor; 2, man efficiency is lower, and construction cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of lifting snap ring of heavy pillar is provided, and this lifting snap ring is simple in structure, easy to use, safe, cost of manufacture is lower, has improved the man efficiency of decoupling device, has reduced construction cost.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of lifting snap ring of heavy pillar, comprise two parallel bars of an end osed top and pin, the other end at these two parallel bars directly upwards is shaped on corresponding pin-and-hole respectively, one end of its pin is shaped on an annulus, this circle diameter is greater than the pin-and-hole diameter, the other end of pin is shaped on anti-skidding nose, and this anti-skidding nose directly upwards is shaped on through hole.
And the cross section of described two parallel bars is circular, and the circular arc sealing of one of an end of two parallel bars.
Advantage of the present invention and beneficial effect are:
1, the lifting snap ring of this heavy pillar comprises two parallel bars of an end osed top and pin, the other end at these two parallel bars is shaped on corresponding pin-and-hole, one end of its pin is shaped on an annulus, this circle diameter is greater than the pin-and-hole diameter, this circular ring structure can effectively prevent pin slippage from pin-and-hole, the endoporus of annulus can be used for rope, utilizes rope to improve the efficient and the safety of high-altitude dismounting pin.
2, the other end of the pin of the lifting snap ring of this heavy pillar is shaped on anti-skidding nose, this anti-skidding nose directly upwards is shaped on through hole, and this through hole can prevent pin slippage in the process of lifting by connecting rope, and this pin only needs to draw with rope along annulus one end, pin can be extracted, improve work efficiency.
3, the cross section of two parallel bars of the lifting snap ring of this heavy pillar is circular, and an end of two parallel bars seals with circular arc, and good looking appearance is connected firmly.
4, the utility model integral structure is simple, easy to use, cost of manufacture is lower, has improved the man efficiency of decoupling device, has reduced construction cost, is the lifting snap ring of the higher heavy pillar of a kind of safety.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of lifting snap ring of heavy pillar, comprise an end osed top two parallel bars 2,3 and pin 7, the cross section of two parallel bars is circular, and an end of two parallel bars seals with the circular arc 1 of one, the other end at these two parallel bars directly upwards is shaped on corresponding pin-and-hole 4 respectively, one end of its pin is shaped on an annulus 8, this circle diameter is greater than the pin-and-hole diameter, annulus endoporus 9 can be used for the colligation rope, pin for convenience detach, the other end of pin is shaped on anti-skidding nose 5, and this anti-skidding nose directly upwards is shaped on through hole 6, and this through hole is used for the colligation rope can improve safety.
The utility model in use, the two ends that bundle the steel rope of heavy pillar are inserted in the lifting snap ring, pin is inserted pin-and-hole to get final product, the annulus endoporus at pin two ends and the through hole colligation rope on the anti-skidding nose, can lift by crane then, behind heavy pillar rigging out in place, the off the hook of commander's crane, two ropes at while Ground Control pin two ends, control the rope of anti-skidding nose and decontrol, the rope of other end colligation pin annulus endoporus is shake firmly, makes the pin landing, snap ring is opened, and finishes the decoupling device operation.
Claims (2)
1. the lifting snap ring of a heavy pillar, comprise two parallel bars of an end osed top and pin, the other end at these two parallel bars directly upwards is shaped on corresponding pin-and-hole respectively, it is characterized in that: an end of pin is shaped on an annulus, this circle diameter is greater than the pin-and-hole diameter, the other end of pin is shaped on anti-skidding nose, and this anti-skidding nose directly upwards is shaped on through hole.
