Suspender having insurance hanging panel and capable of simultaneously lifting two steel rails

Abstract

The invention relates to the technology of track spending, and aims at providing a suspender having an insurance hanging panel and capable of simultaneously lifting two steel rails. The suspender comprises two clamp handles with intersect arrangement, an upper end of the clamp handle is connected with a wire rope, a lower end is an inwardly projected jaw; the suspender comprises at least a snap-ininsurance hanging panel, a through hole is arranged at the upper end of the insurance hanging panel, two sides of the lower end are provided with protruded steps corresponding to the jaw, an intersect position of the through hole arranged at the upper end of the insurance hanging panel and two clamp handles co-uses a mandrel of the clamp handle, and the insurance hanging panel is capable of freely rotating by winding the mandrel of the clamp handle. a stable integral framework is formed between the insurance hanging panel and the suspender main body, stable lifting attitude can be ensured when two steel rails are simultaneously lifted, bearing is balanced, an open angle of the jaw can be conveniently controlled through a jaw folding operating lever, and the positioning effect of a shift rod is used for conveniently fixing the jaw with an opening angle while hoisting. The jaw opens the positioning and departs from the operating lever after the steel rails are clamped, the travelling operation is conveniently carried out, and the labor intensity is mitigated.

Description

technical field [0001] The invention relates to rail hoisting technology, in particular to a hoisting tool with a safety hanging plate capable of hoisting two steel rails at the same time. Background technique [0002] In order to improve work efficiency, rail products on railway frogs are often processed in pairs during production. In consideration of ensuring personal safety, it is necessary to hoist the left and right paired rails to the milling and planing machines for simultaneous pairing processing. From figure 1 It can be seen from the figure that when the monorail is hoisted, the two jaws clamp the rail symmetrically. The rail is a whole with even force on both sides. It will not slip and will not affect the safety of lifting. [0003] Since the conventional spreader is only suitable for lifting a single rail, the above operation method is inefficient. Therefore, operators often forcefully lift two steel rails to improve work efficiency in actual operation. From...

Problems solved by technology

from figure 2 It can be seen from the figure that when the double rails are lifted, the two jaws clamp the two rails symmetrically, but because the two rails are separated from each other, the rail heads lean against each other under the action of the lever force, and the bottoms of the outer rail heads on both sides are pressed When the jaws are hooked, the slope at the bottom of the rail head is tilted up at a large angle and it is easy to slip off; in addition, there is no effective connection between the middle rail heads, only linear contact, which can easily cause the bottom of the rail to turn outward, and the bottom of the rail head is free from the shackles of the jaws ; If there are oil stains on the bottom of the rail head, it is more likely to cause decoupling and cause injury accidents, which is extremely unfavorable for the safe lifting of the rail
