Abstract
The invention discloses a large-tonnage duct piece vacuum suspender power-off safety device which comprises a fixing seat, a shackle, a bolt, a steel wire rope clamp, and a steel wire rope; the fixing seat is fixed at two sides of a vacuum suspender; two ends of the steel wire rope form a circular hoop, and is tightened by the steel wire rope clamp; the shackle has a U shape, and passes through the circular hoop at the steel wire rope ends; an opening end of the shackle is movably connected with the fixing seat through the bolt. The large-tonnage duct piece vacuum suspender power-off safety device of the invention can timely prevent duct piece products from dropping caused by vacuum suspender pressure loss, eliminate potential safety hidden trouble, and has the advantages of simple structure, and convenient operation.
Description
Technical field
The present invention relates to a kind of safety device, especially a kind of large-tonnage section of jurisdiction power-off safety device for vacuum lifting tool.
Background technology
The large-tonnage section of jurisdiction vacuum lifting tool that often uses for template factory, if when the product of handling section of jurisdiction, the prominent powering-off state of meeting if there is no safety method, in case section of jurisdiction vacuum lifting tool decompression will cause the Personal Risk to operating personal, causes the consequence that can not envision.
Summary of the invention
The problem to be solved in the present invention is the deficiency that overcomes in background technology, a kind of large-tonnage section of jurisdiction power-off safety device for vacuum lifting tool is provided, this large-tonnage section of jurisdiction power-off safety device for vacuum lifting tool, can prevent in time that the section of jurisdiction product from dropping because of the vacuum lifting tool decompression, eliminated potential potential safety hazard, and simple in structure, easy to operate.
For addressing the above problem, the present invention takes following technical scheme:
A kind of large-tonnage of the present invention section of jurisdiction power-off safety device for vacuum lifting tool, formed by permanent seat, shackle, bolt, wire rope grip, steel rope, permanent seat is fixed on the both sides of vacuum lifting tool, the two ends of steel rope are bound round into circular, and use the wire rope grip banding, unload and be fastened as " U " shape, penetrate in the annulus of steel cord ends, the open end of shackle is movably connected by bolt and permanent seat.
An innovative approach of the present invention is that described permanent seat is arranged in pairs in the both sides of vacuum chamber, arranges at least two pairs.
When power-off condition occurring, by operating personal in time with this steel wire loop at section of jurisdiction product downside, steel rope both sides are connected in the permanent seat of vacuum lifting tool both sides as above, prevent that the section of jurisdiction product from possible dropping occurring because of the vacuum lifting tool decompression.
A kind of large-tonnage of the present invention section of jurisdiction power-off safety device for vacuum lifting tool, owing to being formed by permanent seat, shackle, bolt, wire rope grip, steel rope, permanent seat is fixed on the both sides of vacuum lifting tool, the two ends of steel rope are bound round into circular, and use the wire rope grip banding, unload and be fastened as " U " shape, penetrate in the annulus of steel cord ends, the open end of shackle is movably connected by bolt and permanent seat.Therefore large-tonnage of the present invention section of jurisdiction power-off safety device for vacuum lifting tool, can prevent in time that the section of jurisdiction product from dropping because of the vacuum lifting tool decompression, eliminated potential potential safety hazard, and had advantage simple in structure, easy to operate.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic side view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of large-tonnage of the present invention section of jurisdiction power-off safety device for vacuum lifting tool, formed by permanent seat 2, shackle 3, bolt 4, wire rope grip 5, steel rope 6, described permanent seat 2 is fixed on the both sides of vacuum lifting tool 1, the two ends of described steel rope 6 are bound round into circular, and with wire rope grip 5 bandings, 3 one-tenth " U " shapes of described shackle, penetrate in the annulus of steel rope 6 ends, the open end of shackle 3 is movably connected by bolt 4 and permanent seat 2.
Described permanent seat 2 is arranged in pairs in the both sides of vacuum lifting tool 1, arranges at least two pairs.
