Abstract
The utility model relates to tower crane hoisting devices for construction, in particular to a protector of a tower crane hook during rope breaking. Friction levers are hinged at two ends of the tower crane hook in a side vertical mode, the lower ends of the friction levers are arranged corresponding to a steel wire rope wound on the lower portion of an inner pulley of the tower crane hook, and the upper ends of the friction levers are connected with a steel wire rope blocking sleeve outside the pulley. Friction blocks are arranged at the lower ends of the friction levers. When the rope breaks, the tower crane hook inclines, the lower ends of the friction levers press and clamp the steel wire rope on the pulley, so that the tower crane hook is clamped without falling off or falls off slowly when the steel wire rope breaks, personal injury and property loss caused by the falling of the tower crane hook are reduced, and usage is safe.
Description
Technical field
The utility model relates to a kind of tower crane lifting appliance for building, i.e. tower crane hook broken rope protector.
Background technology
In the prior art, the construction machinery equipment tower crane is made up of tower body, left and right sides equilibrium arm and lifting hook.The tower crane hook comprises coupler body, and the left and right sides pulley that connects steel rope is arranged in the coupler body.Heavy or steel rope is aging because of hanging article, and wire cable rupture takes place sometimes, and the lifting hook can be rapidly breaks away from bornly with steel rope, and the person and the property safety in building site threatened, and also can damage after the tower crane hook drops, and influences use.
The utility model content
The purpose of the utility model is to above-mentioned deficiency a kind of tower crane hook broken rope protector safe in utilization that improves to be provided.
The technical solution of the utility model is: tower crane hook broken rope protector; It is characterized in that at the vertical friction lever that is hinged with of tower crane hook both end sides; On corresponding settings of steel rope that twine the pulley middle and lower part in friction lever lower end and the tower crane hook, friction lever with pulley outward the steel rope interstage sleeve be connected.There is the friction briquetting friction lever lower end.
The utility model has the advantages that: when disconnected rope; The big coupler body of tower crane tilts; The friction lever upper and lower side is pressed the steel rope on the pulley and is blocked; Block when making tower crane be hooked in wire cable rupture greatly and do not drop or slowly drop, reduce the personal damage and the property damage that drop and cause because of the tower crane hook, safe in utilization.
To combine accompanying drawing that the embodiment of the utility model is described in further detail below.
Description of drawings
Accompanying drawing is the utility model structure diagram.
The specific embodiment
Referring to accompanying drawing, tower crane hook broken rope protector comprises the friction lever 2 that is hinged on tower crane hook 1 two side ends, and friction lever is connected with friction briquetting 4 for 2 times, and friction lever 2 is through rotating shaft 6 and tower crane hook 1 hinged (flexible connection).Friction lever 2 upper end interstage sleeves are (play and the steel rope location, steel rope is blocked in the friction lever upper end when coming off) on steel rope 3; Corresponding settings of steel rope that twine friction lever 2 bottoms and pulley 5 middle and lower parts, friction briquetting 4 (iron and steel piece) surface can be an arc, plays contact with steel rope to increase area and increase rubs.
When the arbitrary steel rope 3 in tower crane hook 1 both sides breaks rope; Tower crane hook 1 tilts to glide; This moment is the friction lever 2 upper end roof pressure steel ropes 3 of opposite side relatively, and steel rope 3 extruding on friction lever 2 lower ends friction briquetting 4 and the pulley 5 are through the contact acting in opposition friction of upper and lower side; Make tower crane hook 1 speed of dropping slow down perhaps pulley 5 to be blocked no longer and drop, realize purpose safe in utilization.
Claims (2)
