Abstract
A quick loading and unloading suspension hook is disclosed herein. An elbow of the suspension hook herein is installed in a small hole of the middle hole of the component; a locating bush is arranged between the middle hole of the component and the vertical rod of the suspension hook; a bearing housing is mounted on the cylinder on the upper part of the vertical rod through a thrust ball bearing, the cylinder being smaller in diameter than the vertical rod; a gasket is arranged through its inner hole on the cylinder and above the trust ball bearing; a nut is arranged on a stud and above the gasket, the stud being on the upper end of the vertical rod; a split pin is arranged in the hole of the nut and the stud. Upon using the suspension hook, a level elbow is put into the small hole of the component and the locating bush is put into the middle hole of the component and the component is subsequently locked and then lifting is done. When the component is lifted to a certain position as required, the locating bush is moved upward so as to escape from the middle hole of the component, which achieved the taking out of the suspension hook. The utility model has the advantages of simple structure, stable locking and convenient loading and unloading.
Description
Technical field
This practical sexual type relates to the production tooling of engineering goods part, loads and unloads suspension hook especially fast.
Background technology
Lifting tool is the important utensil in the machine up of using always, and it finishes the transportation of parts in the processing with lifting appliance, installs.Its basic requirement is that loading and unloading are quick, safe and reliable.For the more complex large-sized part of texture ratio, manufacturing procedure is many, and the installation site also will change thereupon.The position of lifting and the design of instrument are just more important.
Summary of the invention
The purpose of this practical sexual type provides a kind of quick loading and unloading suspension hook, the lifting task of the heavy parts of finishing more complicated safely and fast.
The technical scheme that its technical matters that solves this practical sexual type adopts is: utilize macropore and the aperture vertical in the middle of the part with interstitial hole, hook aperture with the elbow of suspension hook after, be contained in the part interstitial hole with locating bush suspension hook pinned.Behind the rigging out, locating bush is broken away from the part interstitial hole, suspension hook takes out from the hole.
The loading and unloading suspension hook is made up of suspension ring, nut, spring cotter, circlip for bore, thrust ball bearing, bearing case, packing ring, suspension hook and locating bush fast.The horizontal elbow of suspension hook is contained in the interior aperture of part interstitial hole, locating bush is contained between the vertical bar of part interstitial hole and suspension hook all gapped with part interstitial hole and suspension hook, the seat ring of thrust ball bearing is contained in the endoporus bottom of bearing case, the blowout patche of thrust ball bearing is contained on the small column of vertical bar top, circlip for bore is contained in the groove of the top of thrust ball bearing in the bearing case endoporus, packing ring is contained in the top of thrust ball bearing on the small column of vertical bar top by its endoporus, nut is contained in the top of the double-screw bolt upper gasket of the vertical bar of suspension hook upper end, spring cotter is contained in the hole on the double-screw bolt of the vertical bar of nut and suspension hook upper end, and suspension ring are welded on the bearing seat.
Earlier suspension hook is put into the aperture that horizontal elbow that the part interstitial hole makes suspension hook enters part during lifting, then locating bush is put into the part interstitial hole, part is pinned lift by crane.When part be put into need the position after, earlier locating bush is moved up, break away from the part interstitial hole, suspension hook just can take out smoothly.
This advantage of loading and unloading suspension hook fast is: suspension hook is simple in structure, and reliable lock is easy to loading and unloading.
Description of drawings
Below in conjunction with drawings and Examples this practical sexual type is further described.
Accompanying drawing is the quick loading and unloading suspension hook that is used to lift the 16V240ZJ cylinder cover of diesel.
1. suspension ring among the figure, 2. nut, 3. spring cotter, 4. circlip for bore, 5. thrust ball bearing, 6. bearing case, 7. packing ring, 8. suspension hook, 9. locating bush, 10. cylinder cover.
The specific embodiment
16V240ZJ cylinder cover of diesel (10) is the strength member of this diesel engine, has a lot of important holes and plane to need processing above it.Cylinder cover (10) weighs 130 kilograms, must cylinder cover (10) be moved and is in place with lifting appliance and lifting device in the course of processing.70 millimeters of the upper diameter of cylinder cover (10) interstitial hole, have one with the lateral aperture of 28 millimeters of the diameters of its axis normal.
In the accompanying drawings, the horizontal elbow of suspension hook (8) is contained in the aperture on cylinder cover (10) interstitial hole top, for fear of the inside face of the destruction of suspension hook in hoisting process cylinder cover (10) interstitial hole, there is the diameter one section cylinder littler 1～1.5 millimeter than horizontal elbow the inside face intersection of the horizontal elbow of suspension hook (8) and cylinder cover (10) interstitial hole.For the installation of locating bush (9) and convenient to remove, locating bush (9) is 0.1～0.5 millimeter with the tolerance clearance of cylinder cover (10) interstitial hole.Locating bush (9) is 0.1～0.3 millimeter with the tolerance clearance of the vertical bar of suspension hook (8).For cylinder cover (10) when lifting can rotate, the lifting tool design has thrust ball bearing (5), can bear rotation flexibly under the state of gravity.Concrete structure is: bearing case (6) is contained on suspension hook (8) cylinder that vertically the vertical shank diameter of ratio of bar top is little by thrust ball bearing (5).The seat ring of thrust ball bearing (5) is contained in the endoporus bottom of bearing case (6), the blowout patche of thrust ball bearing (5) is contained on the small column of vertical bar top, circlip for bore (4) is contained in the groove of the top of thrust ball bearing (5) in bearing case (6) endoporus, and limit thrust ball-bearing casing (5) moves up.Packing ring (7) is contained in the top of thrust ball bearing (5) on the small column of vertical bar top by its endoporus, nut (2) is contained in the vertically top of the double-screw bolt upper gasket (7) of bar upper end of suspension hook (8), when rotating nut (2) makes thrust ball bearing (5) that suitable gap be arranged, on a face of nut (2), bore spring cotter (3) mounting hole perpendicular to this face.So just can make the hole of construction opening pin (3) on the double-screw bolt on hole that nut (2) goes up construction opening pin (3) and the vertical bar of suspension hook coaxial.The axis in the hole of being bored will with the vertical axes intersect of the double-screw bolt of bar upper end of suspension hook (8).Then, spring cotter (3) is contained in this hole.Connecting fast, the suspension ring (1) of loading and unloading suspension hook are welded on the bearing case (6) securely.
