Abstract

The invention discloses a ratchet wheel positioning anti-falling climbing frame. The frame comprises a guide rail, wall-attached guide bases, anti-falling devices and the like, each anti-falling device comprises an anti-falling wheel, an elastic device and a pair of pawls distributed on the two sides of the corresponding anti-falling wheel, wherein each elastic device is connected between the corresponding pair of pawls and maintains the distance between the pair of pawls by providing pre-tightening force, and ratchet wheel teeth are arranged on the side surface of each anti-falling wheel; andwhen the guide rail ascends, the anti-falling wheels rotate clockwise, and when the ratchet wheel teeth collide with the pawls, the pre-tightening force is overcome by inclined face mutual thrust sothat each pair of pawls are pulled open to enable the ratchet wheel teeth to rotationally pass; and when the guide rail descends, the anti-falling wheels rotate anticlockwise, the ratchet wheel teethmeshes with the pawls when colliding with the pawls to prevent the ratchet wheel teeth from rotationally passing, so that the guide rail is braked, and the guide rail is prevented from descending. Theframe is simple in structure, low in machining cost, convenient to maintain and high in reliability and has an automatic positioning function.

Description

technical field [0001] The invention relates to the construction field, in particular to a ratchet positioning anti-drop climbing frame. Background technique [0002] The current positioning fall arrester for climbing frames has the disadvantages of manual adjustment and positioning, complex structure, high processing cost, high maintenance cost, unreliability and potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a climbing frame for ratchet positioning and anti-falling in view of the above-mentioned defects of the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is to construct a climbing frame for ratchet positioning and anti-falling, including a scaffolding board, a vertical pole, a protective net, a power system, a guide rail fixing device, a guide rail matched with a sliding sleeve and a plurality of attachments. The wall guid...
