Abstract
The utility model relates to a rope breaking protective device for gantry cranes, which belongs to a safety device for gantry cranes. The utility model is composed of a bearing bar, a pulley seat of a hanging cage, springs, a connecting rod and a hook, wherein, the bearing bar is arranged on the upper part of the hanging cage; the pulley seat of the hanging cage and a set of springs are arranged on the bearing bar; the pulley seat of the hanging cage is connected with the hook through the connecting rod. The utility model has the advantages of simple structure and reliable performance.
Description
The utility model belongs to the safety guard of arch type lifter for building.
Arch type lifter is the vertical transportation machinery that a kind of building operation is used; in its working process owing to various reasons; as steel rope fatigue, the unexpected jam of elevator etc.; all may make wire cable rupture; steel rope one fracture; if no corresponding rope broken protector, the construction accident that will be difficult to imagine causes unnecessary consequence.
The purpose of this utility model is the construction safety into arch type lifter, and a kind of rope broken protector is provided.
The purpose of this utility model is achieved in that a kind of rope broken protector of arch type lifter; form by load bar, spring, cage pulley base, connecting rod, hook; the load bar is installed on elevator craning cage top; load bar suit cage pulley base and one group of spring, the cage pulley base is connected with hook by connecting rod.
Simple in structure, the dependable performance of the utility model has good breaking rope protecting ability.
Description of drawings:
Fig. 1 is an arch type lifter rope broken protector scheme drawing
Below in conjunction with accompanying drawing the utility model is further described:
A kind of rope broken protector of arch type lifter; form by load bar 1, spring 2, cage pulley base 3, connecting rod 4, hook 5; load bar 1 is installed on elevator craning cage 6 tops, load bar 1 suit cage pulley base 3 and one group of spring 2, and cage pulley base 3 is connected with hook 5 by connecting rod 4.
Its principle of work is as follows: when the winch of arch type lifter just changes, when cage 6 promoted, the endoporus of cage pulley base 3 upwards slided along load bar 1, and drivening rod 4 is (oblique center) upwards, connecting rod 4 drags hook 5 and breaks away from elevator guide rails frame 7, spring 2 compressions this moment to the rotation of cage 6 centers; When wire cable rupture, cage pulley base 3 rapidly to lower slider, promotes connecting rod 4 at the tension force effect lower edge of spring 2 load bar, makes hook 5 to outward turning, tangles the cross bar of elevator guide rails frame 7, thereby makes cage 6 unlikely tenesmus.
