Description

For the Special fork lifting tool of coiled material, the handling of roll bending class object

Technical field

The invention belongs to fork truck hoist mechanism technical field, be specifically related to a kind of Special fork lifting tool for coiled material, the handling of roll bending class object.

Background technology

Fork truck is as the special transportation device of the class objects such as coiled material, roll bending, and on the goods shelf of forklift hoisting system, mounting boom is common structure form.Prior art products is that boom is directly mounted on the goods shelf of fork truck, utilizes the body of rod of boom to insert the centre hole of roll bending, coiled material, and roll bending, coiled material are loaded and transported.Because the boom body of rod welds, therefore the length of boom is just fixing, can only be suitable for the shipment of certain specification coil of strip, and the coil of strip that specification is not matched cannot be implemented shipment.This external application boom scraper also requires the centre hole of roll bending, coiled material to expose, so that the insertion of the boom body of rod, and just cannot carry out direct scraper with boom for the roll bending as in railroad car; The external diameter of the body of rod of boom is also subject to the center hole size restriction of roll bending, coiled material; And the cross section of the body of rod has determined the bearing load of boom.Along with the development of social production, the centre hole minimum of large-scale roll bending, coiled material all reaches in 350mm, and weight reaches 37000KG left and right; Therefore existing boom difficulty has realized the scraper to the roll bending in small-bore, heavy lift or enclosure space, coiled material, greatly defines the range of use of fork truck at roll bending, coiled material class object.

Summary of the invention

In order to solve the roll bending in small-bore, heavy lift or enclosure space, the scraper of coiled material, the invention provides a kind of Special fork lifting tool for coiled material, the handling of roll bending class object.

Concrete technical solution is as follows:

Special fork lifting tool for coiled material, the handling of roll bending class object comprises the left arm body of two inverted L-shapeds arranged side by side and the right arm body of inverted L-shaped, and the side arm of the two is respectively upright arm, and another side arm of the two is respectively horizontal arm; Between the end of the horizontal arm of the two, connected by pipe link respectively between middle part and between the end of upright arm, form arm body; The parallel center member that is provided with between the horizontal arm of the two; Both sides, center member bottom are provided with L shaped suspension hook by chain respectively; The L shaped suspension hook of described both sides is obvolvent shape relatively; The upright arm top of left arm body and the upright arm top of right arm body are respectively equipped with hook, and bottom respectively correspondence is provided with lower draw-bar.

The uniform installation adjustment hole that offers in described center member bottom, the upper end of two chains of pair of L-shaped suspension hook is buckled in and is installed in adjustment hole by shackle respectively.

The upper end of described every L shaped suspension hook curves inwardly, and outer middle side part is provided with handle, and the hook portion both sides of lower end are respectively equipped with L shaped brace panel, and the upper end of L shaped brace panel is provided with circular arc chamfering; On the upright arm of every L shaped suspension hook, offer pin shaft hole, the axial line of pin shaft hole is parallel with pipe link.

On described every L shaped suspension hook, offer rope hole.

Described pipe link is steel pipe.

The horizontal arm end face of described left arm body and the horizontal arm end face of right arm body are respectively equipped with hanger, and the hanger of the two lays respectively at and the two upright arm adjacent.

The present invention compares with traditional product and has advantages of following aspect:

1, the present invention installs adjustment hole by be provided with a row on center member, unloads the handling that is buckled in the position of installing on adjustment hole and can realizes different in width specification coil of strip by adjustment, and coil of strip maximum width can reach 2100mm;

2, because this suspender is stressed by two L shaped suspension hook two-way simultaneouses, therefore L shaped suspension hook oad is less, can realize the coil of strip scraper of and Heavy Weight little for aperture completely, and minimum-value aperture can reach 200mm, and coil of strip maximum weight can reach 38 tons;

3, the present invention can realize the handling to coil of strip in enclosure space (as coil of strip in the formula railroad car of spacious top), and L shaped suspension hook is connected on arm body by chain, and chain can be by hanging out railway carriage by coil of strip under spacious top in railroad car; The alternative crane of fork truck of equipped this suspender and the fork truck of an equipped boom;

4, because L shaped suspension hook adopts, chain and arm body are flexible to be connected, therefore can reduce road conditions condition poor, shovel the external factors such as goods impact institute's scraper coil of strip collided, the profile of more effective assurance institute scraper goods is intact;

5, the lifting position of suspender of the present invention is positioned at the center of gravity place of whole suspender, when suspender is installed, keeps horizontality, is convenient to the dismounting of suspender, and suspender is hung type, can realization and the quick-replaceable of pallet fork and other generic tool, and raising operating efficiency.
