Detailed Description
The utility model provides an attached ladder stand on transmission line shaft tower high outcrop basis, includes last clamp 10 and lower clamp 20, wherein goes up clamp 10 hoop and establishes on fine aggregate concrete protective cap A, and lower clamp 20 hoop establishes on basic principal post B, goes up the clamp 10 and is connected with the steel member 30 of arranging along basic principal post B cylinder down between the clamp 20, and interval arrangement has the 40 of marking time more than two on this steel member 30.
The utility model provides an attached ladder stand through last clamp 10 with down clamp 20 on fixed stone concrete protective cap A and basic king post B respectively, realize the fixed of cat ladder, the workman just can come and go the maintenance along footboard 40, need not to set up the built-in fitting on basic king post B, just can not destroy basic king post B's integrality yet, reduce the formwork degree of difficulty of whole basis. Meanwhile, the ladder stand is an attachment, so that the ladder stand is very convenient to replace and maintain, simple in structure and low in cost.
The upper end of the steel member 30 extends upward and is bent to form a safety handle 31. The safety handrails are arranged at the position, so that workers can climb conveniently.
The steel member 30 is flat steel, and the steel member 30 is provided with a connecting hole for fixing the step 40 or the lower hoop 20. The steel member 30 is preferably made of flat steel because various connecting holes can be formed in the flat steel, and the steel member is connected by bolts during installation without welding, so that the installation is very convenient.
The upper clamp 10 is welded and fixed on the upper section of the steel member 30, and the lower end of the steel member 30 of the lower clamp 20 is fixed by bolts, preferably anti-theft bolts.
The cross section of the lower clamp 20 is square. When the basic main column B is a square main column, the lower hoop 20 adopts a square hoop.
The cross section of the lower clamp 20 is circular. When the basic main column B is a circular main column, the lower hoop 20 adopts a circular hoop.
