Abstract

The utility model relates to a protection device for preventing derailment of a steel wire rope during the operation process of a crane. The device comprises a pulley cover and is characterized in that transverse rope guard sticks are fixedly arranged on clamp plates on two sides of the pulley cover, a plurality of vertical rope guard sticks are further vertically arranged on the transverse rope guard sticks, and the gap between the longitudinal rope guard sticks and pulleys is smaller than 50% of the diameter of the steel wire rope. The protection device has the beneficial effects that the protection device is additionally mounted at the edge of the steel wire rope of the pulleys, even the position falling of a hanger is excessive and the steel wire rope is sunk into a sleeve, the steel wire rope is clamped by the rope guard sticks, and the steel wire rope is difficult to run out of a pulley groove, thereby significantly reducing the derailment phenomena after the use, greatly reducing the derailment frequency of the steel wire rope and effectively reducing the safety accidents of the crane.

Description

A kind of fender guard that prevents that crane rope from sliding down

Technical field

The present invention relates to prevent in a kind of crane operation process the fender guard of derailment of cable wire.

Technical background

At present, crane operation rate height, most of crane pulley up and down is not to take closed cover, therefore if in operation process, start crane suddenly or when walking while lifting in the process of walking, because crane top and the bottom pulley is the open type cover, steel rope is easy to heavy cover, and in pulley groove, run out of, cause derailment of cable wire, thereby squeeze to hinder squeeze steel rope flat or even break, cause safety misadventure.If all be replaced by closed pulley cover, expense is than higher, and the set-up time is longer, and daily attention is unusual difficulty also, yet there are no crane rope and prevents the fender guard that slides down.

Summary of the invention

Technical problem to be solved in the utility model is to propose a kind of fender guard that prevents that crane rope from sliding down, and it can effectively prevent derailment of cable wire.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of fender guard that prevents that crane rope from sliding down; include the pulley cover; it is characterized in that on the clamping plate of pulley cover both sides, being set with horizontal retaining rope rod, laterally go back vertical row on the retaining rope rod and show several vertically retaining rope rods.

Press such scheme, the gap of described vertical retaining rope rod and pulley is less than 50% of wirerope diameter.

The beneficial effects of the utility model are:

The utility model is installed at the edge of pulley wire rope, the position too much even suspender falls, the heavy cover of steel rope, but because of there being retaining rope rod that steel rope is blocked, steel rope is difficult for running out of to cause in pulley groove sliding down, the phenomenon that slides down after the use obviously reduces, and has greatly reduced the derailment of cable wire number of times, effectively reduces the generation of crane safety misadventure.

Description of drawings

Fig. 1 is the utility model integral structure scheme drawing;

Fig. 2 is the lateral plan of Fig. 1;

Fig. 3 is the birds-eye view of Fig. 2.

Specific embodiments

The utility model is described in more detail below in conjunction with accompanying drawing, but present embodiment can not constitute restriction of the present utility model.

As Figure 1-3; a kind of fender guard that prevents that crane rope from sliding down; include pulley cover 6; on the clamping plate 5 of pulley cover both sides, be set with horizontal retaining rope rod 3; laterally retaining rope rod is as the criterion to guarantee not contact with steel rope 2; laterally on the retaining rope rod also vertical row show several vertically retaining rope rods 4, per two vertically are provided with a pulley 1 between the retaining rope rods, the gap of described vertical retaining rope rod 4 and pulley 1 is less than 50% of wirerope diameter.The utility model installs retaining rope rod additional in case steel rope is run out of from rope race between pulley cover and steel rope, pulley, the material of retaining rope rod device is with round steel or pipe, vertically retaining rope rod can be welded on the pulley cover, its stressed unsuitable load-bearing of the utility model, hang phenomenon so in the handling operating process, should stop askew skewing, otherwise still can cause the phenomenon that slides down.Find by daily use, often occur that center shaft two ends bearing snaps or axis hole is torn problem, generally be exactly at ordinary times to add weldering, reinforce at cover axis hole place now, directly weld sheet iron and get final product.

Claims

1, a kind of fender guard that prevents that crane rope from sliding down includes pulley cover (6), it is characterized in that being set with horizontal retaining rope rod (3) on the clamping plate (5) of pulley cover both sides, laterally goes back vertical row on the retaining rope rod and shows several vertically retaining rope rods (4).

2, by the described fender guard that prevents that crane rope from sliding down of claim 1, the gap that it is characterized in that described vertical retaining rope rod and pulley is less than 50% of wirerope diameter.
