In the prior art, horizontal hoisting or vertical hoisting is generally adopted, so that the lifter can be conveniently and quickly hoisted and fixed under different tower barrel states, and various transportation conditions are used.

When the elevator is vertically hoisted, a bottom section tower drum (except a foundation, the lowest section of the fan tower drum is hoisted firstly), after the assembly of an elevator starting platform and a guide cat ladder is completed, a crane is hoisted by using equipment such as a crane/hoist/crane and vertically lowered, and when the elevator is lowered, a guide wheel device of the elevator is in butt joint with two side ladder frames of the guide cat ladder; and vertically lowering the lifter to the initial platform.

The horizontal hoisting is generally used for hoisting the lifter in advance in a state that the tower barrel is horizontally arranged, and the lifter is clamped into the guide cat ladder in a horizontal sliding mode.

However, in the prior art, due to different hoisting environments of different factories and equipment, fixed hoisting points are preset on the elevator, so that other modes of hoisting cannot be realized by the elevator with the fixed hoisting points, and great inconvenience is caused to the engineering installation progress.

Detailed Description

The lifting structure of the ladder guiding type lifter can be made of the following materials and components, and is not limited to the following materials and components, for example: lifting rings, hinge shafts, a lifter box body and the like.

Fig. 1 is a vertical hoisting structure diagram of a ladder stand guiding type lifter hoisting structure according to an embodiment of the present utility model; the lifting structure of the ladder stand guiding type lifter provided by the embodiment of the utility model comprises the following components: a case 1; the box body 1 is a rectangular box body, and the box body 1 is provided with two corresponding side surfaces; the two side surfaces are respectively provided with a guide component 2 and a hoisting component 3; the hoisting assembly 3 is used for hoisting and installing the whole box body.

Typically, a plurality of groups of guide wheels are arranged on the guide assembly 2; each group of guide wheels comprises two corresponding rail wheels which are used for being connected with the cat ladder.

The lifting structure of the ladder guiding type lifter of the embodiment is mainly used for a lifter connected with a ladder, and therefore the utility model further comprises: a ladder stand; the cat ladder is provided with two parallel guide rails; the box body 1 is connected with the crawling ladder through the guide assembly 2 and is contacted with the parallel guide rail through the rail wheel.

In this embodiment, the case 1 is a welded case.

The guide assembly 2 is provided with a horizontal lifting hook 20 which can be horizontally folded; the lifting assembly 3 is provided with a vertical lifting hook 30 which can be vertically folded.

As shown in fig. 2, two vertical hooks 30 are used for horizontal lifting; in the vertical lifting, as shown in fig. 1, a horizontal hook 20 and a vertical hook 30 are used.

In the embodiment of the utility model, the lifting hooks are arranged on the two side surfaces of the box body, so that the box body can be vertically lifted and horizontally lifted, and the lifting hook structure is foldable, thereby meeting the requirement of installation after lifting.

As in the practical use process, as the horizontal lifting hook and the vertical lifting hook are all foldable structures, collision and interference to other parts can not occur after installation and in the lifting process, the later-stage installation and maintenance are maximally facilitated, the lifting progress is accelerated, and the requirements of horizontal lifting and vertical lifting are met.

The ladder stand guiding type lifter hoisting structure of the embodiment, wherein the two side surfaces are a guiding side surface and a hoisting side surface respectively; the guide assembly 2 is provided with two groups which are respectively arranged at the upper end and the lower end of the guide side surface; the hoisting assembly 3 is provided with two groups which are respectively arranged at the upper end and the lower end of the hoisting side face; the hoisting component 3 and the guiding component 2 are symmetrically arranged on the two side surfaces.

Therefore, when the vertical crane is lifted, the steel wire ropes which are lifted vertically can be connected with the horizontal lifting hook and the vertical lifting hook in equal length, and the gravity center is prevented from being adjusted during the lifting.
