Abstract
The utility model discloses a limiter of a tower crane, which is characterized by comprising a lifting hook, a pulley, a steel wire rope, a touch rod, a spring, a limiter, a sleeve barrel and a steel plate, wherein the lifting hook is connected with the touch rod through the pulley, the touch rod is connected with the spring through the steel wire rope, the pulley is arranged between the touch rod and the spring for converting force-transfer directions, the right side of the spring is connected with the touch rod, the right side of the touch rod is provided with the limiter, a gap between the touch rod and the limiter is 1-2 cm, and the sleeve barrel is arranged outside the spring and the touch rod and fixed on the steel plate. The limiter of tower crane has the advantages of simple structure and strong practicality.
Description
Technical field
The utility model relates to a kind of tower crane limiting device, is applicable to building field.
Background technology
The lifting inhibiting device of tradition tower crane is the touching lever formula, because touching lever is very near apart from the arm point, bumps once with regard to deformation failure, and it is very inconvenient to keep in repair.
The utility model content
The technical matters that the utility model solves provides a kind of tower crane limiting device, solves the problem of traditional tower crane inconvenient maintenance.
The utility model comprises suspension hook, pulley, steel rope, touching lever, spring, limiting device, sleeve, steel plate.Suspension hook links by pulley and touching lever, touching lever links by steel rope and spring, pulley is set between touching lever and the spring changes the power transmission direction, spring right side and touching lever link, the touching lever right side is a limiting device, touching lever and limiting device gap are 1～2cm, and spring and touching lever outside are provided with sleeve, and sleeve is fixed on the steel plate.
The utility model simple structure, practical.
