The two ends of described rivet two are fixed with right panel and left plate respectively.
The two ends of described rivet three are fixed with right panel and left plate respectively.
The utility model compared with the existing technology, devise the structure that rope device grabbed by safety belt, when work high above the ground personnel move up, safety belt is grabbed rope device and is and then moved up, when work high above the ground personnel meet accident fall downwards time, safety belt is grabbed rope device and is laid hold of a rope, and makes work high above the ground personnel can not continue to fall downwards, ensure that the personal safety of work high above the ground personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is explosive view of the present utility model.
See Fig. 2,1 is right panel; 2 is left plate; 3 is lower plate; 4 is limited block; 5 is locking nut; 6 is stop nut; 7 is Limit screw; 8 is spring one; 9 is punching strand rivet; 10 is calvus; 11 is rivet one; 12 is rivet two; 13 is roller; 14 is banking stop; 15 is spring two; 16 is spring three; 17 is handle; 18 is rivet three.
Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 1 and Fig. 2, rope device grabbed by the safety belt that the utility model devises a kind of fall arrest.The surface middle part of lower plate 3 is provided with arc groove, and the left side, surface of lower plate 3 is fixed with left plate 2, and the right side, surface of lower plate 3 is fixed with right panel 1, and calvus assembly to be fixed between left plate 2 and right panel 1 and to be positioned at the top of arc groove.
In the utility model, adopt punching to twist rivet 9 between lower plate 3 and left plate 2 and fix.
The outside of punching strand rivet 9 is arranged with limited block 4, and the lateral grooves of limited block 4 is connected with calvus assembly.
Locking nut 5 and Limit screw 7 is adopted to fix between lower plate 3 and right panel 1, the top of Limit screw 7 is provided with stop nut 6, the side of stop nut 6 is provided with slotted eye, the side of banking stop 14 is stuck in slotted eye, the below of banking stop 14 is provided with spring 1, and the bottom of banking stop 14 is connected with adopting rivet 1 between right panel 1.
Calvus assembly comprises calvus 10, rivet 2 12, roller 13, spring 2 15, spring 3 16, handle 17 and rivet 3 18, the top of calvus 10 is fixed with handle 17, the middle part of calvus 10 is embedded with rivet 3 18, one end of spring 2 15 is set in the middle part of rivet 3 18, the other end of spring 2 15 is connected with the lateral grooves of limited block 4, the rear side of calvus 10 is provided with roller 13, is embedded with rivet 2 12 in the middle part of roller 13, and the two ends of spring 3 16 are connected with rivet 2 12 and rivet 3 18 respectively.
