Description

Safe and efficient oil drum opening tool

Technical Field

The utility model belongs to the technical field of mechanical tool, a safe high-efficient instrument of opening of oil drum is related to.

Background

When opening the oil drum at present, the instrument that operating personnel used all is by two driving levers of U type plectrum or same mechanism principle, supports at oil drum spiral cover rotor plate edge to two contact point centers shear and unscrew the oil drum spiral cover hard as the fulcrum, need screw up one or two teeth with the oil drum spiral cover earlier after having put machine oil, and the same kind mode reverse hard installation of using the instrument to unscrew the oil drum spiral cover is screwed up again.

An instrument of opening oil drum spiral cover as chinese patent CN204529265U discloses comprises dwang, poker rod, and the dwang is long metal round bar, and the poker rod is two short metal poles, and two poker rod parallels are welded at the middle part of dwang perpendicularly, and distance between the outside of two poker rods and the outward flange internal diameter phase-match of oil drum spiral cover, and the distance between the inboard of two poker rods is greater than the width of the rotor in the middle of the oil drum spiral cover. The utility model discloses a rotor plate both sides at the oil drum spiral cover are placed respectively to the lower extreme of two poker rods, to the both ends of opposite direction promotion dwang, two poker rods can form turning moment in the rotor plate both sides of oil drum spiral cover, open the oil drum spiral cover.

The oil drum mode is opened to above-mentioned instrument, and is inefficient, has great safety risk. This post is that take machine oil post, and two driving levers of U type plectrum or the same mechanism principle are less with oil drum spiral cover rotor edge area of contact, and the in-process easily skids hard, easily causes the deformation of oil drum spiral cover rotor, takes place the slippage, collapses to fly, takes off the hand, just can cause staff self hand injury or injure near people slightly carelessly, has certain potential safety hazard. And still need the secondary to take off the spiral cover by hand after unscrewing oil drum spiral cover, waste time. The method for removing and installing the oil drum screw cap cannot meet the existing production safety requirements, so that a novel safe and efficient oil drum screw cap removing and installing tool which has a large contact area with an oil drum screw cap rotating sheet and is provided with a locking mechanism and can remove the screw cap at one time is quite important.

Therefore, the existing oil drum screw cap removing and installing tool mainly has the following two defects:

1. the safety is poor. This post is the engine oil post of taking, and current tool equipment does not have locking mechanism, and the in-process easily skids hard, easily causes oil drum spiral cover rotor plate to warp, takes place the slippage, collapses to fly, takes off one's hand, just can cause staff self hand injury or injure near people slightly carelessly, causes the industrial injury.

2. The efficiency is low. The oil drum screw cap still needs secondary manual removal after unscrewing, wastes time.

In conclusion, it is very urgent to innovate a safe and efficient tool for removing and installing the screw cap of the oil drum. And this kind of new oil drum spiral cover is safe high-efficient demolishs and mounting tool need possess for the instrument that uses at present stage and rotate the piece area of contact great with the oil drum spiral cover, has locking mechanism, can once only take off characteristics such as spiral cover.
