Abstract

The utility model relates to a turning-over lifting hanger. Pin holes with different gap distances are arranged on a horizontal hanging beam. The rotation shaft point on the lower end of a vertical hanging rod which is hinged to both ends of the horizontal hanging beam is provided with a turnover mechanism and the turnover angles can be limited by the turnover mechanism. A tile-shaped movable lock clamping hoop is arranged between the turnover mechanisms of two vertical hanging rods. The turnover mechanism is composed of a toggle rod and a tubular spring directional damper. The utility model has the advantage of simple structure, and an upright cement pipe can be stably turned over into a horizontality safely. The problem in the transporting link of the vertical production process of the cement pipe can be solved. The lifting and the turnover of objects can be combined and completed synchronously. The utility model can be used as a lifting hanger.

Description

The reversible hoisting sling

The utility model belongs to the load suspender of elevator machinery, particularly a kind of reversible hoisting sling that is used to control suspention load.

At present, cement pipe horizontally rotates molding production process, is replaced by the cement pipe production technology of the demoulding immediately after the vertical pouring moulding.In the vertical forming production process, the cement pipe demoulding upright after the moulding need be fallen into horizontality and stack, continue to use existing upset bench board, because of fixing the use location, the operation underaction can't be suitable for.

The purpose of this utility model is, design and produce a kind of reversible hoisting sling, make upright cement pipe or other similar elongated object, add in nothing under the situation of accessory machinery, hydraulic power, from plumbness lentamente, stably tumble into horizontality, make lifting and upset in conjunction with finishing synchronously.

Reversible hoisting sling of the present utility model, comprise horizontal hanging beam, vertical suspension rod, the top lift ring, on horizontal hanging beam, be provided with difference and open the pin-and-hole of shelves, be hinged with vertical suspension rod at the two ends of horizontal hanging beam, in vertical suspension rod lower end rotating shaft place the switching mechanism that can limit tip-over angle is installed, switching mechanism is provided with toggle link, following toggle one end of toggle link is fixed on the gusset plate, the toggle link upper end is equipped with the directed damper of sleeve, the sleeve pipe upper end of damper is hinged on the top of vertical suspension rod, and the active locking clip of tile of replaceable diameter width is installed between the switching mechanism of two vertical suspension rods.

Using method of the present utility model is that selection is installed on the vertical suspension rod, and adjusts the vertical suspension point of vertical suspension rod on horizontal hanging beam with the locking clip that the object diameter width that is lifted by crane and overturn is consistent; Hoisting sling is hung on the suspension hook of overhead traveling crane or crane, the active locking clip of tile is held tightly be reversed object and locking, be reversed the center of gravity of object this moment above the active locking clip of tile.After object is lifted by crane built on stilts, by the manpower guiding, make the object by gravity, oppositely slowly to tumble to the directed damper of sleeve, this moment, the damper inner spring was compressed, and object is turned round and is turn 90 degrees, and is stabilized in horizontality at last; Put down suspension hook, unclamp clip, clip resets into original vertical state to be hung.

The utility model has the advantages that: simple and reasonable, need not external machinery, under the auxiliary situation of hydraulic power, safely with upright cement pipe or other similar elongated object, lentamente, stably tumble into horizontality, solved the carrying link in the vertical production technology of cement pipe, realized object lifting and upset easily in conjunction with finishing synchronously, become the special-purpose hoisting sling of a kind of simple and easy actv., and filled up the blank of China in this technology.Be applicable to cement pipe or other similar elongated object of upright placement, stably tumble into the heavy suspender of reversible of horizontality from plumbness.

Below in conjunction with drawings and Examples, the utility model will be further described:

Fig. 1 is the structure schematic front view of the utility model reversible hoisting sling;

Fig. 2 is the structure diagrammatic side view of the utility model reversible hoisting sling,

Fig. 3 is the upset working state figure of reversible hoisting sling upset cement pipe.

As seen from Figure 1, reversible hoisting sling of the present utility model, comprise horizontal hanging beam 1, vertical suspension rod 2, top lift ring 3, on horizontal hanging beam, be provided with difference and open the pin-and-hole 4 of shelves, be hinged with vertical suspension rod 2 at the two ends of horizontal hanging beam, at vertical suspension rod lower end rotating shaft 5 places the switching mechanism 10 that can limit tip-over angle is installed, the active locking clip 6 of tile of replaceable diameter width is installed between the switching mechanism of two vertical suspension rods.

As seen from Figure 2, switching mechanism is provided with toggle link 7, and following toggle one end of toggle link is fixed on the gusset plate 8, and the toggle link upper end is equipped with the directed damper 9 of sleeve, and the sleeve pipe upper end of damper is hinged on the top of vertical suspension rod.

As seen from Figure 3, the cement pipe axis turns over and turn 90 degrees, and the following toggle of switching mechanism is upright state, and toggle link stretches in the directed damper of sleeve, and cement pipe is the level of state.
