[0039] The following is an explanation of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0040] It should be noted that, in the present utility model, the up, down, left and right in the figure are regarded as the up, down, left and right of the multifunctional hoist suitable for hoisting buildings on arches described in this specification.

[0041] The exemplary embodiments of the present invention are now introduced with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0042] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0043] This embodiment relates to a multifunctional lifting device suitable for hoisting buildings on arches. Figure 1 and Figure 2 The multifunctional sling includes a sling beam 20, a lower sling lug 30 and a steel wire rope 50. Specifically, a plurality of lower sling lugs 30 are arranged on the lower surface of the sling beam 20, and the intervals between two adjacent lower sling lugs 30 are the same or different.

[0044] like Figure 1 As shown, the sling beam 20 is arranged along its entire length, the cable hoist is connected to the sling beam 20 through a rope, and a plurality of lower lifting ears 30 are welded to the bottom surface of the sling beam 20 at intervals. In some embodiments, the arrangement of the plurality of lower lifting ears 30 can be referred to Figure 1 .

[0045] The hanger beam 20 is a three-web box-type structure made of welded steel plates, and its length is the same as the width of a single bridge deck.

[0046] Two upper lifting ears 10 are installed on the upper surface of the hanger beam 20 . The distance between the two upper lifting ears 10 is half of the total length of the hanger beam 20 . The two upper lifting ears 10 are welded to the hanger beam 20 symmetrically about the perpendicular midline of the hanger beam 20 .

[0047] In order to enhance rigidity and ensure stability, the upper lifting lug 10 and the lower lifting lug 30 are both welded with stiffening plates.

[0048] The steel wire rope 50 is suspended on the lower lifting lug 30 to hoist the arch structure. Specifically, a shackle 40 is installed on each lower lifting lug 30, and the steel wire rope 50 is hung on the lower lifting lug 30 through the shackle 40. The length of each steel wire rope 50 is different. The final length of the steel wire rope 50 is determined by calculating the cross slope of the bridge deck to ensure that the component always remains horizontal during the hoisting process.

[0049] In addition, the arch structure includes arch columns, cap beams, steel beams, bridge decks, etc.

[0050] Depending on the type of arch structure to be hoisted, in some embodiments, refer to Figure 1 The multiple lower lifting ears 30 include at least the following four types, namely, column lifting ears 31, cap beam lifting ears 32, steel beam lifting ears 33, and bridge deck lifting ears 34.

[0051] like Figure 1 As shown, along the length direction of the hanger beam 20, a lower lifting ear 30 is installed at the midpoint thereof, and the lower lifting ear 30 is used as a bridge deck lifting ear 34 for lifting the bridge deck or a cap beam lifting ear 32 for lifting the cap beam. That is to say, the lower lifting ear 30 located at the midpoint of the hanger beam 20 can be used for lifting the bridge deck and also for lifting the cap beam. Specifically, Figure 4 The following is an application diagram for lifting bridge deck. Figure 5 The figure shows the application when hoisting the cap beam.

[0052] Please continue reading Figure 1 Along the midpoint to the end of the hanger beam 20, a steel beam lifting lug 33 for lifting the steel beam, a column lifting lug 31 for lifting the column, and a bridge deck lifting lug 34 for lifting the bridge deck are also installed on the hanger beam 20.

[0053] Please continue reading Figure 1 In some implementations, specifically, 11 lower lifting ears 30 are provided in total. According to the arch building components lifted by the lower lifting ears 30, the 11 lower lifting ears 30 are divided into column lifting ears 31 for lifting columns, cap beam lifting ears 32 for lifting cap beams, steel beam lifting ears 33 for lifting steel beams, and bridge deck lifting ears 34 for lifting bridge decks.

[0054] exist Figure 1 In the figure, the arch building to be hoisted is marked with words above each lower lifting ear 30.

[0055] The specific distribution and lifting process of the 11 lower lifting ears 30 will be described in detail below.

[0056] It should be noted that since the left and right sides of the cap beam are hoisted at the same time, Figure 5 As shown, one cap beam requires two multifunctional slings to lift it simultaneously, and at this time, the lower lifting ear 30 at the midpoint of the sling beam 20 is called the cap beam lifting ear 32.

[0057] A midpoint perpendicular line is drawn through the midpoint of the hanger beam 20. Two bridge deck lifting ears 34 are also installed on the lower surface of the hanger beam 20. The two bridge deck lifting ears 34 are arranged symmetrically about the midpoint perpendicular line. That is, a total of three bridge deck lifting ears 34 are arranged on the hanger beam 20. Figure 4 The multifunctional hoist can lift three bridge decks at the same time. In order to avoid mutual influence, Figure 4 As shown, there is a height difference between the three bridge decks, which can be achieved by adjusting the length of the steel wire rope 50 under the bridge deck lifting eye 34.

[0058] Please continue reading Figure 1 Four column ears 31 are installed on the lower surface of the hanger beam 20. The four column ears 31 are symmetrically arranged about the midpoint of the hanger beam 20. The upper ear 10 is directly above the two column ears 31 on the same side of the midpoint.

[0059] Please continue reading Figure 1 Four steel beam lifting lugs 33 are installed on the lower surface of the hanger beam 20, and the four steel beam lifting lugs 33 are symmetrically arranged about the mid-vertical line of the hanger beam 20. Figure 1 The four steel beam lifting ears 33 are numbered sequentially from left to right in the direction shown. It can be seen that the first steel beam lifting ear 33 and the fourth steel beam lifting ear 33 are located at the left and right ends of the hanger beam 20, respectively, while the second steel beam lifting ear 33 and the third steel beam lifting ear 33 are close to the midpoint of the hanger beam 20. In this way, the multifunctional hanger can ensure that the steel beam remains horizontal in the air when the steel beam is lifted. The lifting state is shown in FIG. Figure 3 .

[0060] For the distribution of the 11 lower lifting lugs 30, please continue to refer to Figure 1 Between the two steel beam hanging ears 33 on the same side of the mid-perpendicular line is a bridge deck hanging ear 34 and two column hanging ears 31, and the two column hanging ears 31 are adjacent to each other; one of the steel beam hanging ears 33 is close to the end of the hanger beam 20.

[0061] like Figure 1 As shown, the 11 lower lifting ears 30 are, from left to right, a steel beam lifting ear 33, a bridge deck lifting ear 34, two column lifting ears 31, a steel beam lifting ear 33, a bridge deck lifting ear 34 / cap beam lifting ear 32, a steel beam lifting ear 33, two column lifting ears 31, a bridge deck lifting ear 34, and a steel beam lifting ear 33.

[0062] It is worth mentioning that, in some embodiments, the length of the steel wire rope 50 corresponding to each lower hanging lug 30 is calculated by the transverse slope of the bridge deck, and the length of the steel wire rope 50 is controlled to ensure that the building component on the arch maintains a horizontal posture in the air.

[0063] The multifunctional lifting device provided in this embodiment can realize lifting various types of arch buildings with the same lifting device. Only the lower lifting ear connected to the arch building needs to be replaced, and the lifting device itself does not need to be replaced. Therefore, this embodiment solves the problem of frequent replacement of lifting devices when lifting arch buildings.

[0064] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
