Abstract

The utility model belongs to the technical field of hoisting equipment and relates to an unpowered horizontal automatic hoisting device of sheet coil. The utility model is characterized in consisting of a triangular carrier-beam 1, a vertical member 2, a horizontal bar 3, a hook 4, a guide rod 5 and a guide plate 6. At the utility model, the upper section of guide rod 5 can slide up and down inside the triangular carrier-beam 1 along a shaft sleeve; the lower section of guide rod 5 has a rigid connection with the guide plate 6 for an integral entity. The upper section of vertical member 2 has a hinge connection with the triangular carrier-beam 1; the lower section of vertical member 2 has a hinge connection with the middle of horizontal bar 3. The upper section of hook 4 has a hinge connection with the triangular carrier-beam 1; the medium section of hook 4 has a hinge connection with one end of the horizontal bar 3 the other end of which is equipped with a roller 9 which can move in a slide channel at the guide plate 6 on which are equipped internal and external slide channels which can connect each other and form a close circulation. In addition, a lower unilateral valve disk 7 and an upper unilateral valve disk 8, which can automatically return after opening, are equipped at a node position at the slide channel. The utility model is horizontally symmetrical. As a pure mechanical automatic structure, the utility model is characterized in simple structure, lower cost and lower power consumption.

Description

Horizontal coiled sheet automatic shutter lifter

Technical field

The utility model belongs to the weight-lifting equipment technical field, relates to the suspender that metallurgy industry uses, and specially refers to a kind of unpowered horizontal coiled sheet automatic lifting device.

Background technology

The horizontal coiled sheet automatic lifting device of having used at present, the unlatching of its hook all is to provide power by auxiliary motor with closed, realizes by transmission devices such as reductor, leading screw screw or reductor, chain sprocket.This complex structure, cost height, power consumption are big.

Summary of the invention

The purpose of this utility model is the unpowered horizontal coiled sheet self-lift that a kind of later-model pure physical construction will be provided.

The technical solution of the utility model is that this lifter mainly is made of parts such as triangle drop in beam 1, montant 2, horizon bar 3, hook 4, guide rod 5, guide plates 6.The upper end of guide rod 5 can slide up and down by the direct-axis cover in the middle of triangle drop in beam 1; Lower end and guide plate 6 are rigidly connected and are integral, and montant 2 upper ends and triangle drop in beam 1 are hinged; Lower end and horizon bar 3 middle parts are hinged, link up with 4 upper ends and triangle drop in beam 1 is hinged; The middle part is hinged with an end of horizon bar 3, and the other end of horizon bar 3 is provided with roller 9; Roller 9 can move in the slideway on the guide plate 6, and guide plate 6 is provided with the slideway of inside and outside two intercommunications that can form close cycle, but and after slideway node place is provided with unlatching the following unidirectional valve 7 and the last check valve 8 of self-return.The entire mechanism left-right symmetric.See figure one.

Effect of the present utility model and benefit are: simple in structure as the self-lift of Purely mechanical, cost is low, saves electric power resource.

The specific embodiment

Below in conjunction with technical scheme and accompanying drawing, be described in detail the specific embodiment of the present utility model by four steps in the working cycle of lifter.

The first step, lifter is unloaded to descend and the hook gathering

The hook 4 of light condition lifter is open, and the roller 9 on the horizon bar 3 is in the upper end of outside slideway.Lifter descends, when guide plate 6 and guide rod 5 touch just stop motion of coiled sheet 10, lifter continues to descend, roller 9 beginnings on the horizon bar 3 move downward along guide plate 6 outside slideways, owing to be subjected to stopping of check valve 8, slide into inboard slideway, hook 4 inwardly draws under the action of gravity of self.See figure two～figure four.

In second step, the lifter band carries lifting

Under hook (4) rounding state, lifter rises, and roller rises to guide plate 6 inboard slideways upper ends, at this moment links up with 4 and mentions coiled sheet 10 and rise together.See figure five.

In the 3rd step, the lifter band carries decline and hook opens:

The lifter band coiled sheet 10 and is descended, and when fall earthward guide rod 5 and guide plate 6 of coiled sheet 10 just stopped motion, lifter continues to descend, and roller 9 is along with moving down, back down down unidirectional valve 7 enter outside slideway.Horizon bar 3 outwards promotes hook 4 opens it.See figure six～figure seven.

In the 4th step, lifter is unloaded to rise:

When the lifter zero load is risen.Roller 9 moves up in the slideway of the outside of guide plate 6, backs down check valve 8 and arrives slideway upper end, the outside.See figure eight.

So far lifter has been realized unpowered the unlatching in closure, finishes a working cycle, returns to initial condition.
