Abstract
Chain type forestope fixed ring, including channel steel, it is welded with the half of round steel pipe in the lower end of the channel steel, in the upper end of the channel steel, there are one round steel for welding, the upper end welding of round steel is there are one nut, and the side of the channel steel is fixedly welded with one end of cucurbit chain, and there are one link up with made of diameter 8mm reinforcing bars for the other side welding of the channel steel, it is movably installed with a S types hook on hook, the other end of cucurbit chain is hung on S types hook.Its purpose is to provide a kind of construction safeties ensureing operator, reduce labor intensity, the chain type forestope fixed ring improved labor efficiency.
Description
Technical field
The present invention relates to chain type forestope fixed rings.
Background technology
To ensure the construction safety of boring head top plate foreset safety and operating personnel, change traditional sleeve
Formula forestope ring uses, and reduces labor intensity, and realizes forestope directly to Forward construction of meeting head on, and improves forestope by removing speed,
Reduce the top plate sky top time.
Invention content
The purpose of the present invention is to provide a kind of construction safeties ensureing operator, reduce labor intensity, and improve labour effect
The chain type forestope fixed ring of rate.
Chain type forestope fixed ring of the present invention, including channel steel are welded with the half of round steel pipe in the lower end of the channel steel,
The upper end welding of the channel steel is there are one round steel, and there are one nut, welding is fixed in the side of the channel steel for the upper end welding of round steel
There is one end of cucurbit chain, there are one the other side welding of the channel steel links up with made of diameter 8mm reinforcing bars, activity peace on hook
There are one S types to link up with for dress, and the other end of cucurbit chain is hung on S types hook.
The S types hook is by diameter 18mm, and the anchor pole of long 2250mm is made.
Chain type forestope fixed ring of the present invention realizes that forestope directly to Forward construction of meeting head on, props up top plate in advance temporarily
Shield achieves preferable effect；It reduces labor intensity, improves labor efficiency, essential safety has been accomplished at scene.
Chain type forestope fixed ring of the present invention is described further below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the front view of chain type forestope fixed ring structural schematic diagram of the present invention.
Specific implementation mode
As shown in Figure 1, chain type forestope fixed ring of the present invention, including channel steel 1, it is welded with circle in the lower end of the channel steel 1
The half of steel pipe, in the upper end of the channel steel 1, there are one round steel 2 for welding, and there are one nut 3, the slots for the upper end welding of round steel 2
The side of steel 1 is fixedly welded with one end of cucurbit chain 4, and there are one be made of diameter 8mm reinforcing bars for the other side welding of the channel steel 1
Hook 5, be movably installed with the other end that cucurbit chain 4 is hung on S type hook 6, S types hook 6 on hook 5, the S types are hung
Hook 6 is by diameter 18mm, and the anchor pole of long 2250mm is made.
In use, channel steel 1 can be screwed to by nut 3 above on anchor pole, realize that forestope is directly constructed to Forward of meeting head on,
Forestope is improved by speed is removed, preferable effect is achieved to top plate foreset.
