The utility model aims to provide a safety device which is safe in lifting, can tighten a hanging strip to prevent a duct piece from sliding down and can fix a top duct piece and a lower duct piece.
Description
Technical Field
The utility model relates to the technical field of lifting appliances, in particular to a safety device for lifting pipe pieces.
Background
With the development of economy in China, engineering construction by utilizing underground space is more and more, and particularly, shield construction is most widely applied to underground engineering construction. The segment is an important ring in hoisting from the ground to a shield foundation pit in shield construction, generally 3 segments are hoisted, the total hoisting weight generally reaches more than 12 tons due to the large mass of the concrete segments, and the segment is hoisted downwards from the ground to the shield foundation pit at high altitude, so that the risk is great. What used commonly at present is that adopt two cloth suspender to live the section of jurisdiction pocket and hoist, the risk of suspender landing is very big, and the section of jurisdiction of hoist and mount simultaneously generally is 3 layers, and the block of capping is smaller, generally puts at the top, does not fix below with, has the risk of dropping. Therefore, there is a need for a safety device that can secure the lifting straps to prevent the duct piece from slipping and fix the top duct piece to the lower duct piece.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide a safety device which is safe in lifting, can tighten up a hanging strip to prevent a duct piece from sliding down and can fix a top duct piece and a lower duct piece.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
a safety device for hoisting pipe pieces comprises at least three hanging strips, wherein the hanging strips are symmetrically hung at the bottom of the bottom-most pipe piece, a skid is arranged between the pipe pieces, first binding strips are bound on the side parts of the hanging strips between the bottom-most pipe piece and the upper pipe piece, and second binding strips are bound between the top pipe piece and the lower pipe piece; the first binding belt is composed of a safety hook and a steel sleeve ring which are connected through a steel wire rope, and the safety hook and the steel sleeve ring are mutually buckled on the side part of the binding belt to form a closed loop; the second ligature belt is composed of a lifting hook and a steel sleeve ring which are connected through a binding belt, and the second ligature belt is adjusted and tightened through an adjusting fastener arranged on the binding belt.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model is safe to lift, and the first binding belt can tighten the hanging strip, so that the hanging strip is prevented from deviating to the two sides of the duct piece, and the duct piece is prevented from sliding off. The second ligature area can tie up the less section of jurisdiction that lies in the top with the next layer section of jurisdiction mutually tightly, avoids the section of jurisdiction of the top landing when the handling.

Detailed Description
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
As shown in fig. 1 to 3, a safety device for hoisting pipe pieces comprises at least three hanging strips 9 for hoisting pipe pieces 8, wherein the hanging strips 9 are symmetrically hoisted at the bottom of the bottommost pipe piece 8, skids 7 are arranged between the pipe pieces 8, first binding belts 1 are bound on the side parts of the hanging strips 9 between the bottommost pipe piece 8 and the upper pipe piece 8, and second binding belts 2 are bound between the uppermost pipe piece 8 and the lower pipe piece 8; the first binding belt 1 is composed of a safety hook 3 and a steel sleeve ring 4 which are connected through a steel wire rope, and the safety hook 3 and the steel sleeve ring 4 are mutually buckled at the side part of the hanging belt 9 to form a closed loop; the second binding belt 2 is composed of a hook 5 and a steel sleeve ring 4 which are connected through a binding belt, and the second binding belt 2 is adjusted to be tightened through an adjusting fastener 6 arranged on the binding belt.
The utility model is safe in lifting, the first binding belt 1 is bound on two sides of the hanging strip 9 between the bottommost side duct piece 8 and the upper duct piece 8, so that the left side and the right side of the two hanging strips 9 are relatively tightened towards the middle part, and meanwhile, the hanging strips 9 are not excessively tightened to move towards the middle part due to the pressure influence of the duct piece 8 on the hanging strips 9, so that the hanging strips 9 are prevented from deviating towards the two sides of the duct piece 8 to avoid the duct piece 8 from sliding off.
The second ligature belt 2 can be tightly bound with the lower segment 8 of the segment 8 on the top side, and the segment 8 on the top side is prevented from sliding down during lifting by adjusting the tightener 6 to tighten the bandage.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
