The utility model comprises a set of grab hooks [6], wherein, both ends of which are symmetrical; the outer sides of the upper ends of the grab hooks are respectively penetrated with driving rods [5]; the center of the grab hooks is provided a mechanical driving device [4] which is composed of six n-shaped steel plates and is provided with an orthohexagonal cross section; a motor [1] is fixed at the top part of the mechanical driving device; the lower end of the motor besides shaft teeth is fixedly provided with a driving lead screw which is coincided with the lower end of the motor, the upper end of the driving lead screw is provided with a toothed wheel [3], and the lower end of the driving lead screw is coincided with an orthohexagonal bottom edge inner nut; the driving device and the driving rods between the grab hooks are composed of a Y-shaped hoisting lifting rod [2]. The utility model has the advantages of concise structure, quick hoist, stability, safety, power saving, flexible operation and convenient operation.

Description

The round section bar suspender

The utility model belongs to the additional device of lifting machine.

The finished product operation of station, harbour, place, warehouse and produced on-site, overhead traveling crane lifting finished product commonly used, the handling thing that steel rope is tied up, especially it is rounded, oval or be not regular circular strapping goods very to tie up the back section, as strapping goods such as screw-thread steel, round steel, steel pipe, special section, small-sized angle bar, PVC plastic pipes.Though simple, need manually tie up, labour intensity is big, easily produces safety hazard, inefficiency.

It is fast, steady, safe and reliable that the purpose of this utility model provides a kind of handling, and economize on electricity and flexible and convenient operation have the section bar suspender of fixing device.Especially tie up the rounded article in back and play sling.

A kind of grapple that has, gear, motor, mechanical drive and the round section bar suspender that lifts by crane suspension rod, it is characterized in that two ends are symmetrical, one group of grapple [6] that side-looking face is S-shaped, the grapple upper end outside penetrate respectively from the cross section be hexagonal mechanical drive the drive link [5] that passes of junction, limit, [cross section formed of shape iron plate is orthohexagonal mechanical drive [4] by six in the middle of the grapple, the mechanical drive top is fixed with motor [1], motor lower end hexagon top margin inner shafts tooth is other be fixed with its upper end that coincide be the turn-screw of gear [3], nut in lower end and the hexagon base coincide, and is fork-shaped lifting suspension rod [2] between driving device and grapple on the drive link.

This suspender is by drive motor, mechanical drive, and turn-screw, grapple, suspension bracket is formed.Mechanical drive be one by six [shape iron plate is formed.When motor rotates, utilize the principle of parallelogram, leading screw rotating band motivation tool driving device just can be done motion up and down, drive drive link and do opening and closing movement, drive link drives grapple and makes corresponding action, the both sides pawl is put down open, and opens the back maximum, two drive links distance hour, the opening maximum of grapple.The opening minimum of two drive links grapple during apart from maximum, three pawls that can make grapple are intersected between mutually, reach the form of taking up, and handling article getting hold of steadily, can not produce landing.When handling steel article, the grapple requirements for quality of suspender is higher.Grapple will have certain rigidity and toughness, grapple distortion when preventing the big article of lift heavy amount, the landing of handling article.The machine up of at this moment carrying out grapple need be forged and be beaten and quench, if handling PVC plastic product has volume but do not have weight, grapple can be used the plate iron cutting processing, and mechanical drive also can be finished by machine up.This suspender can have different array modes.According to producing varying in weight of product, the scale difference can adopt different combinations.As: grapple+mechanical drive+grapple or grapple+mechanical drive+grapple+mechanical drive+several patterns such as grapple.

The utility model has the advantages that structure is terse, handling is fast, stable, safe and reliable, economize on electricity and flexible and convenient operation.

Accompanying drawing 1 is a round section bar hanger structure scheme drawing, and accompanying drawing 2 is a mechanical drive part-structure scheme drawing, 1-motor wherein, and 2-lifts by crane suspension rod, 3-gear, 4-mechanical drive, 5-drive link, 6-grapple, 7-leading screw.

Of the present utility modelly be embodied as suspension hook and driving device can be made of steel plate, motor, gear, leading screw, the equal buyable of drive link, and install by figure and to connect.
