Detailed Description

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other.

In the description of the utility model, it should be understood that the terms "center," "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships that are based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the utility model and simplify the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be configured and operate in a particular orientation, and therefore should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", etc. may explicitly or implicitly include one or more such feature. In the description of the utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the creation of the present utility model can be understood by those of ordinary skill in the art in a specific case.

The utility model will be described in detail below with reference to the drawings in connection with embodiments.

The utility model provides a component hoist device, as shown in fig. 1 through 3, includes steel strand bundle 1, and this steel strand bundle both ends are passed the pre-buried pipe 4 of component reserved hole site respectively, and anchor assembly 3 is all installed to the one end that the steel strand was worn out the pre-buried pipe, and the protection tube 2 of suit in the steel strand bundle outside is installed to the pre-buried pipe upper end. When the component is hoisted, the hoisting device is usually used in pairs, a group of hoisting devices are respectively arranged at two ends (sides) of the component, when the component is hoisted, the steel strand bundle can be adaptively deformed, the hoisting process is high in stability and good in reliability, and the hoisting device is simple and convenient to install and remove, so that the influence on the structure of the component is very small.

As an example, the anchors described above employ clip anchors. Two ends of the steel strand bundle are anchored on the concrete member or the steel member by adopting clamping piece anchors, and the steel strand bundle penetrates into the bending wire dividing pipe to form a hanging point. And when the hoisting is completed, the hoisting is completed through direct connection of the lifting appliance/lockset, and when the hoisting is removed, the clamping piece anchors are removed at the anchoring ends, so that the removal of the steel strand bundle lifting lugs can be completed.

In an alternative embodiment, the pre-buried pipe is a threaded pipe. The protective tube adopts a bendable yarn dividing tube, and a person skilled in the art can select a commercially available yarn dividing tube product. The wire dividing pipe is provided with the connectors connected with the embedded pipes at two ends respectively, the two ends of the wire dividing pipe are fixed to the embedded pipes respectively through the connectors, the wire dividing pipe is convenient to install and detach, the wire dividing pipe can effectively protect the internal steel strands, and the service life of the steel strand bundles is prolonged.

The steel bar gravity center adopted by traditional hoisting is not easy to determine, the gravity center is usually determined by repeated test hoisting, the hoisting can be successfully performed, and when the hoisting device is used for hoisting a component, the steel strand can adaptively deform and can self-adaptively reach balance, the gravity center is not required to be aligned for many times, so that the component hoisting operation can be performed rapidly and stably, time and labor are saved, and the operation efficiency is high.

The outside of the protective tube is provided with a spiral reinforcing rib 5 which covers below the combination position of the protective tube and the embedded tube. In an alternative embodiment, according to the working condition, a person skilled in the art can set a rib plate at the lower side of the embedded pipe, and the acting force of the anchoring piece (such as a clamping piece anchorage) is shared by the rib plate, so that the local damage of the component is avoided.

The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the present utility model, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
