Abstract

The invention discloses a lifting device which can be used for lifting objects with long and thin lifting holes, wherein a lifting ring is fixed at the top of the lifting device, one end of a T-shaped sliding sleeve rod is sleeved with a lifting rod, the other end of the T-shaped sliding sleeve rod is sleeved with an end cover, and the third end of the T-shaped sliding sleeve rod is connected with a fixed hook body through a spiral torsion compression spring; on the other hand, the shaft end part with the safety limit groove on the sliding sleeve rod and the fixed hook body form clearance sliding fit, a spring is sleeved on the safety locating pin and meshed with the safety limit groove, and the lifting rod is welded with the fixed hook body; the T-shaped sliding sleeve rod is twisted by a certain angle to be opposite to the end of the lifting rod, the T-shaped sliding sleeve rod is pushed to twist and compress the spiral torsion compression spring, the T-shaped sliding sleeve rod moves in the sliding cavity, the lower end of the T-shaped sliding sleeve rod is sleeved on the lifting rod, and the T-shaped sliding sleeve rod is continuously pushed to enable the safety positioning pin to be meshed and locked with the limiting groove under the action of the spiral compression spring.

Description

A kind of overhead hoist

Technical field

The present invention relates to a kind of overhead hoist, especially: can be used in lifting eye is leptosomatic handling thing.

Background technology

At present, known hoist lifting hook is a hook formation, generally only is applicable to that the hook block lifting eye is the article of ring-type, under some specific work environments, lifting eye is thin long hole, and at this moment common suspension hook is just inoperative, in order to address this problem, invention provides a kind of overhead hoist.

Summary of the invention

The object of the invention is to provide a kind of overhead hoist that can be applicable to elongated hole.

Technical solution of the present invention: overhead hoist is made up of fixed hook body, suspension ring, T type sliding bar set, end cap, insurance locating dowel pin, handling bar; Fixedly suspension ring are equipped with at the top of fixed hook body, and the fixed hook body is a hollow cavity, and the one end is provided with the end cap of band endoporus, and the other end is installed with the insurance locating dowel pin, and fixed hook body lower end is connected with the handling bar; T type sliding bar set left end shaft and end cover clearance bearing fit, the right-hand member axle is provided with the insurance position-limited trough, the right-hand member axle is connected with the fixed hook body by cylindrical screw twist compression spring, and form the gap bearing fit with the fixed hook body, T type sliding bar set lower end is provided with handle hole, handle hole and handling bar gap bearing fit; The end cap of described fixed hook body has link stopper; The insurance locating dowel pin is provided with compression spring; T type sliding bar set is provided with the insurance position-limited trough, and cylindrical screw twist compression spring is cylindrical, and one end and cavity are affixed, and the other end and T type sliding bar set are affixed.

The present invention has following advantage:

The invention provides a kind of handle hole is elongated pass article overhead hoist, simple in structure, reliable working performance, easy and simple to handle, practical.

Specific embodiments

At Fig. 1, Fig. 2-1, present embodiment among Fig. 2-2, fixedly suspension ring 1 are equipped with at the top of fixed hook body 5, fixed hook body 5 is a hollow cavity, fixed hook body 5 one ends are provided with the band endoporus, the end cap 8 of band link stopper, the other end is installed with insurance locating dowel pin 4, T type sliding bar set 7 middle parts (axle) and sliding cavity 9 gap bearing fits, two ends, the left and right sides are axle, left end shaft and end cap 8 form the gap bearing fit, the right-hand member axle is connected with fixed hook body 5 by cylindrical screw twist compression spring 2 on the one hand, have the axial end portion and the fixed hook body 5 that insure position-limited trough on the other hand and form the gap bearing fit, T type sliding bar set 7 right-hand members are provided with the insurance position-limited trough; Insurance locating dowel pin 4 one ends pass fixed hook body 5 and insert in the sliding cavity 9, be with the cylindroid helical-coil compression spring 3 that is in compressive state on the insurance locating dowel pin 4, insurance locating dowel pin 4 meshes with the insurance position-limited trough of T type sliding bar set 7, there are a handling bar 6 patchholes (being handle hole) T type sliding bar set 7 lower ends, handle hole and handling bar 6 are gap bearing fit work, and fixed hook body 5 is connected (welding) with handling bar 6.

Fig. 3, shown in Figure 4 earlier penetrates the handling bar 6 on the fixed hook body 5 the elongated patchhole of sample upper end, and it is locked up to insurance locating dowel pin 4 to promote T type sliding bar set 7 then, prepares handling.

Load handling thing working process: the handle hole of T type sliding bar set 7 lower ends is aimed at handling bar 6, be specially to promote T type sliding bar set 7 and compress and reverse cylindrical screw twist compression spring 2, T type sliding bar set 7 in sliding cavity 9, i.e. slip rotation again; T type sliding bar set 7 lower ends are socketed on the handling bar 6 by handle hole then, it is locked with the insurance position-limited trough engagement of T type sliding bar set 7 right-hand members under the effect of cylindroid helical-coil compression spring 3 until insurance locating dowel pin 4 to continue to promote T type sliding bar set 7, insurance locating dowel pin 4 is under the effect of cylindroid helical-coil compression spring 3, keep insurance position-limited trough engagement (less power) locked T type sliding bar set 7 with T type sliding bar set 7, finish dead work, at this moment just can the handling article.

Unloading handling thing working process: behind the intact article of handling, pulling insurance locating dowel pin 4, insurance locating dowel pin 4 breaks away from the insurance position-limited trough of T type sliding bar set 7, cylindrical screw twist compression spring 2 begins rotation and extends, T type sliding bar set 7 outwards slides in sliding cavity 9 under the effect of cylindrical screw twist compression spring 2, T type sliding bar set 7 breaks away from handling bar 6 in the effect lower slider of cylindrical screw twist compression spring 2, after breaking away from handling bar 6, still keep sliding and begin vertical handling bar 6 and rotate, promptly slide and rotate again, terminate at last and end cap 8 link stopper contact positions, make T type sliding bar set 7 and fixed hook body 5 form certain pivot angle, become the initial condition of suspender, this swash angle position can provide enough motion spaces, be convenient to handling bar 6 and extract and insert in the lifting eye of handling thing, finish the loading and unloading of handling thing.
