Abstract
The invention discloses a steel-plate lifting clamp. The steel-plate lifting clamp comprises a left clamping arm, a right clamping arm, a spring and a down-pressing opening clamping arm part, wherein the left clamping arm and the right clamping arm are hinged into a pincer shape by a pin shaft; the spring is positioned under the pin shaft, one end of the spring is connected on the left clamping arm and the other end of the spring is connected on the right clamping arm; the down-pressing opening clamping arm part comprises a connecting arm and a lifting lug; the two ends of the connecting arm are respectively provided with a ball; the positions of the inner sides of the left clamping arm and the right clamping arm, which are positioned above the pin shaft, are respectively provided with a rolling groove; the balls are respectively positioned in the rolling grooves; and the lifting lug is arranged on the middle part of the connecting part. The steel-plate lifting clamp disclosed by the invention has the advantages that in use, a downward force is applied on the down-pressing opening clamping arm part, the lower ends of the left clamping arm and the right clamping arm are opened and cross at the two ends of a steel plate, then when in lifting, the left clamping arm and the right clamping arm are closed to hold the steel plate, and when in lifting and transporting, the phenomenon that the steel plate inclines or falls down difficultly occurs, and reclamping is not needed, so that the operating efficiency is increased and the lifting and transporting safety is improved simultaneously.
Description
Technical field
The present invention relates to a kind of crane hoisting special purpose tools, be specifically related to a kind of steel plate suspension clamp.
Background technology
Steel plate is to use pouring molten steel, and the tabular steel that compacting forms after the cooling are widely used in the machinery manufacturing industry.In machinery manufacturing industry enterprise, for some small-sized thinner steel plates, can adopt artificial directly carrying, but this steel plate can not well satisfy the needs of making, and is not widely used.And some large-scale thicker steel plates, characteristics can be good at satisfying the needs of making because intensity is good etc., are widely used.Because the quality of large-scale thicker steel plate is heavier, also can't adopt artificial directly carrying, need to use the lifting tool handling.Need to be by means of lifting hook of steel plate when using the lifting tool handling; the not tight phenomenon of clamping usually can appear in existing lifting hook of steel plate in use, and then steel plate can tilt or fall down when the lifting tool handling, needs clamping once again; operating efficiency is low, and safe lifting is poor.
Summary of the invention
Technical matters for above-mentioned existence the objective of the invention is: proposed the steel plate suspension clamp that a kind of clamping is firm, operating efficiency is high and safe lifting is high.
Technical solution of the present invention is achieved in that a kind of steel plate suspension clamp, comprises left jig arm, right jig arm, spring, presses down and strut the jig arm parts; Described left jig arm and right jig arm are hinged to pincer by bearing pin, described spring is positioned at the bearing pin below and an end is connected on the left jig arm, the other end is connected on the right jig arm, and described pressing down struts the jig arm parts and comprise connecting arm, hanger, and described connecting arm two ends are respectively equipped with ball; Have rolling groove in described left and right jig arm inboard and above being positioned at bearing pin; Described ball lays respectively in the rolling groove; Described hanger is arranged on the connecting arm middle part.
Preferably, described left and right jig arm end is respectively arranged with the folding hook; Described folding hook is the side direction bending in the suspension clamp for corner iron.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
A kind of steel plate suspension clamp of the present invention, during use, give the downward power of jig arm parts one that struts that presses down, left and right jig arm lower end is opened and is bridged at the steel plate two ends, afterwards, and when lifting, left and right jig arm closure is also embraced steel plate, be difficult for during handling the phenomenon that steel plate tilts or falls down occurs, do not need again clamping, improved safe lifting when increasing operating efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is a kind of steel plate suspension clamp structural representation of the present invention;
Accompanying drawing 2 is a kind of steel plate suspension clamp open mode structural representation of the present invention;
Wherein: 1, left jig arm; 2, right jig arm; 3, spring; 4, bearing pin; 5, connecting arm; 6, hanger; 7, ball; 8, rolling groove; 9, folding hook.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2 is a kind of steel plate suspension clamp of the present invention, comprises left jig arm 1, right jig arm 2, spring 3, presses down and strut the jig arm parts; Described left jig arm 1 and right jig arm 2 are hinged to pincer by bearing pin 4, described spring 3 is positioned at bearing pin 4 belows and an end is connected on the left jig arm 1, the other end is connected on the right jig arm 2, and described pressing down struts the jig arm parts and comprise connecting arm 5, hanger 6, and described connecting arm 5 two ends are respectively equipped with ball 7; Inboard and be positioned at bearing pin 4 tops and have rolling groove 8 in described left and right jig arm 1,2; Described ball 7 lays respectively in the rolling groove 8; Described hanger 6 is arranged on connecting arm 5 middle parts; During use, the hanger 6 stressed connecting arms 5 that press down, the ball 7 at connecting arm 5 two ends is along rolling groove 8 down slidings, left and right jig arm 1,2 bottom is opened and is bridged at the steel plate two ends, during lifting, hanger 6 upwards spurs connecting arm 5 and moves up, left and right jig arm 1,2 bottom makes the bottom embrace tighter and tighter to steel plate under the effect of spring 3, is difficult for occuring the phenomenon that steel plate tilts or falls down when making handling.Left and right jig arm 1,2 end is respectively arranged with folding hook 9, and folding hook 9 is the side direction bending in the steel plate suspension clamp, guarantees to be fallen the stability of object, is difficult for dropping, and safety performance is good.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
