Detailed Description

The invention is further described below with reference to the accompanying drawings.

The invention relates to a detachable foot nail for a steel pipe tower of a power transmission line, which is matched with a part without foot nails at the lower part of the tower body of the steel pipe tower for climbing, and comprises a foot rest lever 21, wherein the foot rest lever is fixed at the outer side of the lower part (end) of a vertical supporting arm 10 which is in a vertical state when in use, the upper part (end) of the vertical supporting arm is fixedly connected with one side arm of a U-shaped clamping body 11, and during manufacturing, the detachable foot nail can be directly bent into a Z shape according with safety standards, wherein the cross bar at the lower end is the foot rest lever, and then the cross bar at the upper end is bent to form a U shape with the vertical bar, namely the U. And manufacturing a support buckle 12 matched with the arc of the periphery of the tower body, and then welding and fixing the support buckle at the lower part (end) of the vertical support arm in the direction opposite to the pedal rod.

The U-shaped clamping body, the vertical supporting rod and the pedal rod can be respectively manufactured and then welded and fixed or directly cast (forged) and formed.

In order to ensure the operation safety, a plurality of anti-skid bulges 2 are manufactured on the pedal rod, and an anti-skid rod 3 is manufactured at the outer end of the pedal rod.

The foot lever may be formed as a rod-shaped foot lever 21 or a plate-shaped foot pedal 22, and if the foot lever is formed as a plate-shaped foot pedal, a plurality of ribs 13 are welded between the vertical support bar and the foot pedal.

The tower body lower part of steel-pipe tower is for not having fixed foot nail tower body, lays the interval according to normal foot nail and sets up removable foot nail placement point, and each placement point cutting one with removable foot nail U type joint body corresponding joint hole 4, the highly short arm length than the U type joint body in joint hole is slightly big, is convenient for lay and take out.

During the operation, the removable foot nail U type joint body that will carry inserts the joint hole, and the arc supports buckle 12 and the radial laminating of steel-pipe tower, and the upper and lower steel-pipe tower of this removable foot nail of operation personnel accessible. After the operation is finished, the utility model is taken away with the hand.
