As preferably, bottom described trolley shoe, there is cylindrical mounting groove.Be slightly less than the diameter of rolling bearing by the diameter of mounting groove, both pass through tight fit connection.
As preferably, the port, bottom of described vertical rod is arranged with Anti-slip cover.Anti-slip cover can increase the frictional force of double ladder and bottom surface, strengthens security performance.
As preferably, the end of described connection cord has pull head.The setting of pull head makes operator better capture and act on connection cord, humanization designing.
As preferably, described rail bar one and described rail bar two are all in " 7 " font and both are symmetrical, and the sliding part that described rail bar one and rail bar two comprise protrusion and the fixed part be connected with described sliding part, described fixed part is connected on the outer wall of described vertical rod.Guide rail simple and practical, improves production efficiency, reduces cost of production in batch production, in actual production, and can according to actual conditions designed, designed.
Compared with prior art, this steel work double ladder has the following advantages:
1, this steel work double ladder is from practical problem, and by structure optimization, by arranging the box that can slide along vertical rod, operator is saved labour, has stronger practicality.
The box of 2, this steel work double ladder is tied with connection cord, operator can pull connection cord that box can be made to slide when double ladder differing heights, obtain the instrument wanted, increasing degree has been saved the labour of operator, fetching tool is climbed down without the need to climbing up, very convenient.
3, have rolling bearing with box junction bottom this steel work double ladder trolley shoe, box has the cylindrical connecting portion of protrusion, connecting portion is plugged in described bearing.When operator is positioned at another ladder row, often can there is not phenomenon smoothly in the instrument of taking away in box, by the setting of rolling bearing, the rotatable box of operator reaches desirable angle of taking, and designs very hommization.
4, the port, bottom of the vertical rod of this steel work double ladder is arranged with Anti-slip cover.Anti-slip cover can increase the frictional force of double ladder and bottom surface, strengthens security performance.
