fig. 2 is a schematic view of an installation structure of the device for embodying the present invention.

In the figure, 11, the left lower plate; 111. a left lifting lug; 12. a right lower plate; 121. a right lifting lug; 21. a card slot; 22. a first clamping block; 3. an upper plate; 31. a second fixture block; 4. a connecting bolt; 5. and (7) hanging holes.

Detailed Description

The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.

Example 1: a combined special lifting appliance for unit curtain walls is shown in figures 1 and 2 and comprises a lower plate and an upper plate 3, wherein the lower plate and the upper plate 3 are combined to be connected with an upper cross beam of a unit curtain wall plate, and then the upper plate 3 and the lower plate are used for lifting the unit curtain wall plate.

It can be understood that the upper cross beam of the unit curtain wall plate is provided with a connecting groove for connection, the top surface notch of the upper cross beam of the unit curtain wall plate is provided with two clamping pieces, and a clamping groove 21 is formed between the clamping pieces and the inner side wall of the upper cross beam of the unit curtain wall plate.

The hypoplastron combines on unit curtain wall plate entablature through draw-in groove 21, specifically as follows:

the hypoplastron is located inside unit curtain plate entablature, and the both sides of the top surface notch department of unit curtain plate entablature all are equipped with the decurrent draw-in groove 21 of opening, are equipped with on the hypoplastron to inlay the first fixture block 22 of establishing in draw-in groove 21, are equipped with the lug on the hypoplastron.

It can be understood that be equipped with first fixture block 22 on the hypoplastron, because the opening of draw-in groove 21 is downward, then first fixture block 22 inlays to be established in draw-in groove 21 and can realize being connected with unit curtain wall plate entablature, when hoist and mount, stress can be through first fixture block 22 dispersion to draw-in groove 21 on, can not make stress concentration at a position of unit curtain wall plate entablature.

In order to improve stability, this scheme still is provided with upper plate 3, specifically as follows:

upper plate 3 is located unit curtain plate entablature upside, and 3 both sides of upper plate are equipped with the second fixture block 31 with the lateral wall laminating of unit curtain plate entablature, has seted up the lug hole on upper plate 3, and the lug hole supplies the lug to stretch out in upper plate 3 top.

The upper plate 3 and the lower plate are connected by a connecting member, for example, the connecting member may include a connecting bolt 4, and a connecting hole for connecting the connecting bolt 4 is formed between the upper plate 3 and the lower plate.

In practical application, the hanging holes 5 are formed in the lifting lugs, and the hanging requirement can be met.

This embodiment does not adopt the mode of punching at unit curtain plate entablature to hoist, but utilize the draw-in groove 21 of unit curtain plate entablature top surface notch department, utilize first fixture block 22 block in draw-in groove 21 with the hypoplastron of this device, realize the support of hoist and mount, combine 3 second fixture blocks 31 of upper plate to the fixed of unit curtain plate entablature lateral wall simultaneously, and with the combination of hypoplastron, realize the stable combination of this device, the stability is improved, then utilize lifting device to hoist the lug, because on this scheme hoist and mount the unit curtain plate entablature with power dispersion during hoist and mount, rather than concentrating on a hole department, stability and security when can improving hoist and mount.

Example 2: a combined type lifting appliance for unit curtain walls, which is different from the lifting appliance in embodiment 1, as shown in fig. 1 and 2, the lower plate comprises a left lower plate 11 and a right lower plate 12, the lifting lugs comprise a left lifting lug 111 positioned on the left lower plate 11 and a right lifting lug 121 positioned on the right lower plate 12, the left lower plate 11 and the right lower plate 12 are abutted with each other, and the left lifting lug 111 and the right lifting lug 121 are abutted with each other.

It can be understood that this scheme is with hypoplastron split into left hypoplastron 11 and right hypoplastron 12, then left hypoplastron 11 is connected with unit curtain wall plate entablature left side draw-in groove 21, and right hypoplastron 12 is connected with unit curtain wall plate entablature right draw-in groove 21.

The symmetry combination hoist of disconnect-type about this scheme adopts, the installation of being convenient for on the one hand, and on the other hand can avoid stress concentration at a position of hypoplastron, further improvement device's stability and security.

It can be understood that, due to the two hanging lugs, the hanging holes 5 need to be formed in the two hanging lugs, and the hanging holes 5 in the two hanging lugs need to be aligned with each other.

As mentioned above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the invention itself.
