Description
Technical field
The utility model relates to a kind of hanging device, specifically relates to a kind of automatic clamping steel plate pincers.
Background technology
Steel plate pincers is a kind of common tool that is used to load and unload various steel plate on chain or the hoist cable that is installed in, be widely used in occasions such as bulk storage plant, dock, harbour, station, steel market, steel plate pincers has to be made simply, and the intensity height loads and unloads advantages such as easy, but it is a large amount of artificial auxiliary that steel plate pincers of the prior art usually needs when the loading and unloading steel plate, if not assist before the lifting, be clipped in steel plate pincers on the steel plate and tilt or fall down, just clamping again, efficient and safety are very low, the shipping and delivery cost height.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple and reasonable, high efficiency, automatic clamping steel plate pincers that safety performance is good are provided.
The purpose of this utility model realizes by following technical scheme: described automatic clamping steel plate pincers comprises hook-shaped caliper and pincers tongue, offer caliper hole and pincers tongue hole on it respectively, one bearing pin passes the caliper hole and with pincers tongue hole the two is connected, it is characterized in that: also comprise torsion spring, described hook-shaped caliper upper portion side wall is provided with the outer hole of torsion spring, described bearing pin spindle nose is provided with the torsion spring endoporus, gib head and outer gib head in described torsion spring is provided with, torsion spring set is contained on the bearing pin, interior gib head is inserted in the torsion spring endoporus, and outer gib head is inserted in the outer hole of caliper; Described pincers tongue hole inwall and bearing pin offer corresponding pincers tongue groove and bearing pin keyway, and the pincers tongue is connected transmission with bearing pin by flat key.
The afterbody of described bearing pin offers dowel hole, and bearing pin end joint connection fluted nut, locating dowel pin are contained in the dowel hole and are stuck in the groove of fluted nut.
As further improvement of the utility model, the clamping contact site of described hook-shaped caliper, pincers tongue and steel plate is provided with anti-skidding groove.
The utility model compared with prior art, by between ordinary steel wrench upper clamp and pincers tongue, torsion spring being set, make and to clamp automatically between caliper and the pincers tongue, can firmly clamp steel plate during lifting, only need a small amount of artificial assisting to overcome the problem that steel plate pincers tilts or falls down, improve handling efficiency, improved safety, reduced cost.
