Abstract
The utility model discloses a lifting appliance with a sling tensioning device, which is used for lifting a prefabricated part stacking frame and comprises a lifting frame, a sling and an auxiliary rod, wherein the lifting frame comprises two longitudinal beams and a plurality of cross beams connected with the two longitudinal beams, and two ends of each longitudinal beam are connected with the sling; the method is characterized in that: and a sling tensioning device is further arranged in the middle of each longitudinal beam, and two ends of the auxiliary rod are respectively connected with the sling tensioning device. The utility model discloses a hoist uses the auxiliary rod to increase interim hoisting point when lifting by crane the PC component of irregular or focus serious skew, guarantees to hang stability, and this improvement version's hoist can effectively take up the hoist cable, reaches and lifts by crane the requirement. The scheme is produced and applied in batches in my department, the accident rate of the original scheme is about 0.5%, and the accident rate can be reduced to 0.05% by the improved scheme. The lifting safety is improved.
Description
Technical Field
The utility model relates to a hoist with hoist cable overspeed device tensioner belongs to hoist technical field for the prefabricated building.
Background
As shown in fig. 1, the prefabricated composite floor slabs are stacked in layers and stacked on a composite slab transportation frame 5 in a manner of layering battens in the middle, and are lifted and transferred by using a dedicated composite slab transportation frame hanger. The superimposed slab transportation frame usually has 4 fixed hoisting points, and the corresponding lifting appliance is equipped with 4 picture pegs, inserts the hoisting point of superimposed slab transportation frame and lifts by crane. The gravity center of some prefabricated parts with irregular shapes deviates from the axis of a lifting point, and the lifting point must be increased to ensure the stable and safe lifting. As shown in fig. 1, a rigid auxiliary rod 3 is used to assist lifting, two ends of the auxiliary rod 3 are connected with slings 2, and the other ends of the slings 2 are connected with a lifting appliance or directly wound on a lifting frame 1, so that 2 temporary lifting points are added. According to the scheme, 2 hoisting points can be temporarily increased, but in the implementation process, due to the lack of a tensioning device, the sling is loosened, and the hoisting requirement cannot be met; if the sling is manually tensioned, the efficiency is low, and the tensioning effect is difficult to meet the lifting requirement.
SUMMERY OF THE UTILITY MODEL
In order to increase the hoisting point of hoist reliably, the utility model provides a hoist with hoist cable overspeed device tensioner, concrete technical scheme is as follows.
A lifting appliance with a sling tensioning device is used for lifting a prefabricated part stacking frame and comprises a lifting frame, slings and auxiliary rods, wherein the lifting frame comprises two longitudinal beams and a plurality of cross beams connected with the two longitudinal beams, and the slings are connected to two ends of each longitudinal beam; the method is characterized in that: and a sling tensioning device is further arranged in the middle of each longitudinal beam, and two ends of the auxiliary rod are respectively connected with the sling tensioning device.
Further, the sling tensioning device is directly connected with the auxiliary rod or the sling tensioning device is connected with the auxiliary rod through a sling.
Further, the sling tensioning device is an electric hoist or a hand hoist.
Furthermore, a lifting lug is arranged on the longitudinal beam, a through hole is formed in the lifting lug, and the sling tensioning device are installed on the lifting lug.
Further, the sling tensioning device is mounted at 1/2 of the longitudinal beam.
Furthermore, the longitudinal beam and the cross beam are made of I-shaped steel and connected in a welding mode.
Adopt the utility model discloses a hoist, when lifting by crane the PC component of irregular or focus serious skew, use the auxiliary rod to increase interim hoisting point, guarantee to hang stability, this improve the hoist of version can effectively tensioning hoist cable, reaches and lifts by crane the requirement. The scheme is produced and applied in batches in my department, the accident rate of the original scheme is about 0.5%, and the accident rate can be reduced to 0.05% by the improved scheme. The lifting safety is improved.
