Abstract
The utility model discloses a kind of tower machine protection device about rope jumping of improvement, comprise hoisting drum, lifting rope and suspension hook, one end of described lifting rope is fixed on metope, other end volume is located at hoisting drum, described suspension hook is installed in a lifting hook pulley group, described lifting rope successively by row rope pulley, tower top leading sheave and slewing tower leading sheave, then is connected with lifting hook pulley group by after an amplitude variation trolley assembly pulley.The utility model utilizes amplitude variation trolley assembly pulley to promote amplitude as adjustment lifting rope, ensure that lifting rope is drawing high the stability in process, a lifting hook pulley group will be set on suspension hook simultaneously, instead of directly suspension hook be fixed on a movable pulley, the stability of the overall operation of whole tower crane can be ensured like this, lifting rope is not easy to come off from dolly or assembly pulley, the stability of guarantee equipment and safety, the utility model structure is simple, reasonable in design, easy to install, range of use is wide.
Description
Technical field
The utility model relates to tower machine technology field, the tower machine protection device about rope jumping of particularly a kind of improvement.
Background technology
Chinese tower crane starts from the 1950's.Make a general survey of 50 years development histories, Chinese tower crane industry is grown out of nothing, from small to large, progressively define comparatively rounded system, become China and develop one of machinery industry faster.Tower machine industry has formed a set of comparatively sound mechanism in design, manufacture, management and market development etc.Dolly part is used for installing assembly pulley and steel cable and suspension hook, is also direct part of the force; Existing tower machine steel rope be in use subject to comparatively heavy articles pulling force time, easily depart from dolly or assembly pulley, cause safety misadventure.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of tower machine protection device about rope jumping of the improvement that can solve the problem.
The utility model in order to the technical scheme solving its technical matters and adopt is: a kind of tower machine protection device about rope jumping of improvement, comprise hoisting drum, lifting rope and suspension hook, one end of described lifting rope is fixed on metope, other end volume is located at hoisting drum, described suspension hook is installed in a lifting hook pulley group, described lifting rope successively by row rope pulley, tower top leading sheave and slewing tower leading sheave, then is connected with lifting hook pulley group by after an amplitude variation trolley assembly pulley.
As further improvement of the utility model, described lifting hook pulley group is made up of three movable pulleys, and described three movable pulleys are arranged at three tops of a spider respectively, and described suspension hook is installed on a horizontal edge of spider.
As further improvement of the utility model, described row's rope pulley, tower top leading sheave and slewing tower leading sheave are all fixed on metope,
The beneficial effects of the utility model are: the utility model utilizes amplitude variation trolley assembly pulley to promote amplitude as adjustment lifting rope, ensure that lifting rope is drawing high the stability in process, a lifting hook pulley group will be set on suspension hook simultaneously, instead of directly suspension hook is fixed on a movable pulley, the stability of the overall operation of whole tower crane can be ensured like this, lifting rope is not easy to come off from dolly or assembly pulley, the stability of guarantee equipment and safety, the utility model structure is simple, reasonable in design, easy to install, range of use is wide.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Indicate in figure: 1-hoisting drum; 2-lifting rope; 3-suspension hook; 4-lifting hook pulley group; 41-movable pulley; 42-spider; 5-rope pulley; 6-rope pulley; 7-slewing tower leading sheave; 8-amplitude variation trolley assembly pulley.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
Fig. 1 shows a kind of embodiment of the tower machine protection device about rope jumping of a kind of improvement of the utility model, comprise hoisting drum 1, lifting rope 2 and suspension hook 3, one end of described lifting rope 2 is fixed on metope, other end volume is located at hoisting drum 1, described suspension hook 3 is installed in a lifting hook pulley group 4, described lifting rope 2 is successively by row's rope pulley 5, tower top leading sheave 6 and slewing tower leading sheave 7, be connected with lifting hook pulley group 4 by after an amplitude variation trolley assembly pulley 8 again, described lifting hook pulley group 4 is made up of three movable pulleys 41, described three movable pulleys 41 are arranged at three tops of a spider 42 respectively, described suspension hook 3 is installed on a horizontal edge of spider 42.Described row's rope pulley 5, tower top leading sheave 6 and slewing tower leading sheave 7 are all fixed on metope.
