Abstract

A dual-purpose fall protection device for an angle iron and glide tack iron tower comprises a body (1), an angle iron hooking part (G1) and a glide tack hooking part (G2) which are arranged at the upper section thereof and a hooking hole (K) which is arranged at the lower section thereof; (G1) and (G2) are integrated; the angle iron hooking part (G1) consists of a horizontal hook (14) which can move up and down and a hooking part (1A) which is arranged at the upper section of the body (1); the horizontal hook (14) can move up and down with the movement of a ratchet wheel bracket (3), the body is provided with a through groove for the movement of the ratchet wheel bracket (3) along the length direction of the body (1); the ratchet wheel bracket (3) comprises a front panel (2) and a rear panel (4) which are arranged at the front and rear sides of the body (1), and a coil of a wire (7) and a ratchet wheel (5) which are arranged at the shaft (9) of the ratchet wheel bracket (3) in a coaxial and rotary way; the front panel (2) is provided with a horizontal pawl handle (10) and a rear panel (4) is provided with an upper and lower pawl handle (18), the upper and lower pawl handle (18) is toggled to cause the pawl to clamp the hook body (1) and the horizontal pawl handle (10) is toggled to cause the pawl the clamp the ratchet wheel (5), so that the movable ratchet wheel bracket (3) is fixed at the hook body. Therefore, body (1) is tightly fixed to hook the angle iron, guaranteeing the safety of construction.

Description

technical field [0001] The invention relates to a safety device for climbing an iron tower, and more specifically, the invention relates to a dual-purpose anti-falling device for an iron tower with angle steel and foot nails. The dual-purpose fall prevention device for angle steel and foot spike iron tower is suitable for the safety insurance of the climbing operation of the angle iron frame iron tower and the foot spike iron tower. Background technique [0002] In the construction of ultra-high voltage iron towers, in order to prevent the accidental fall of the construction workers who climbed the iron tower, the method of ordinary hooks and ropes is usually adopted for protection. But the hook of this method has no locking and positioning device, which is troublesome to operate and poor in safety. [0003] "200710077796.0", the title of the invention is "A Falling Prevention Method During Transmission Line Tower Climbing" discloses a falling prevention method during trans...
