[0027] There are four groups of lifting ears 30 , which are respectively arranged on the top wall of the hanger 10 . The transverse support member 50 is arranged on the hanger 10 , and the transverse support member 50 includes a first cross beam 501 and a second cross beam 502 .

[0028] The first beam 501 is arranged on the hanger 10, the second beam 502 is arranged below the first beam 501, and the fastening assembly 40 is respectively connected to the first beam 501 and the second beam 502. The adjustment assembly 60 is arranged on the second beam 502, the stop column 70 is arranged on the hanger 10, and the fixing plate 80 is arranged on the second beam 502.

[0029] It should be noted that the first crossbeam 501 described in this embodiment is movably arranged on the hanger 10, and the second crossbeam 502 is connected to the first crossbeam 501 through the guide column 601. The adjustment component 60 is adjusted according to the weight of the bridge deck and the angle required for lifting during the lifting process of the bridge deck. The stop column 70 strengthens the overall stability of the hanger 10, and the fixing plate 80 is connected to the bridge deck in a limiting manner, which strengthens the overall stability of the bridge deck during the lifting process of the bridge deck.

[0030] In one embodiment of the present invention, Figure 3 As shown, the fastening assembly 40 includes a first connecting rod 401 , a pin clamping plate 402 , a second connecting rod 403 , a fastener 404 , a pin 405 and a positioning shaft 406 .

[0031] The first connecting rod 401 is rotatably disposed on the first crossbeam 501, the pin clamping plate 402 is disposed on the first connecting rod 401, one end of the second connecting rod 403 is rotatably disposed on the first connecting rod 401, and the second connecting rod 403 is connected to the pin clamping plate 402.

[0033] In one embodiment of the present invention, Figure 4 As shown, the adjustment assembly 60 includes a guide column 601 , an adjustment valve stem 602 , a valve steel 604 and a hook 603 .

[0034] The two ends of the guide column 601 are respectively connected to the first beam 501 and the second beam 502 , the regulating valve stem 602 is detachably arranged on the second beam 502 , the hook 603 is rotatably arranged on the guide column 601 , and the valve steel 604 is installed on the hook 603 .

[0035] It should be noted that the guide column 601 includes a hollow sleeve and a movable guide column. The movable guide column is movably arranged in the hollow sleeve, and the movable guide column moves in a limited position in the hollow sleeve to limit the moving distance of the movable guide column, so that when adjusting the distance between the first beam 501 and the second beam 502, they are connected and fixed through the movable guide column.

[0036] In one embodiment of the present invention, Figure 1 As shown, the lifting ear 30 is provided with round holes, the round holes are in five groups, and the lifting ear 30 is provided with reinforcing ribs.

[0037] A plurality of round holes are provided on the lifting lug 30, and the number of the round holes is designed according to the actual situation, and no specific requirements are made here. It is convenient for a crane or a driving vehicle to connect the hanger 10 through a steel wire rope, and multiple groups of round holes allow the steel wire rope to be placed in different positions, adjust the center of gravity of the hanger 10, and change the inclination angle of the hanger 10 at will, so as to facilitate the angle of installation on the construction site.

[0038] In one embodiment of the present invention, Figure 1 As shown, the fixing plate 80 is provided with a limiting hole, and the limiting hole of the fixing plate 80 is connected to the steel bars on the side of the bridge deck.

[0039] It should be noted that the limiting holes on the fixing plate 80 are connected to the steel bars extending from the side of the bridge deck. The fixing plate 80 is quickly connected to the steel bars to further support the bridge deck, making it more stable during the lifting process.

[0040] Furthermore, round steel is provided on the fixing plate 80, and grooves matching the round steel are provided on the side panels of the bridge deck. The round steel is engaged in the grooves and simultaneously cooperates with the steel bars to be inserted into the limiting holes on the fixing plate 80, thereby ensuring good stability during lifting.

[0041] In one embodiment of the present invention, Figure 1 As shown, the positioning pin chain 202 is an L-shaped chain plate, and corresponding positioning holes are respectively provided on the positioning pin chain 202 and the hanger 10, and the positioning pins 201 are inserted into the positioning holes.

[0042] It should be noted that the two ends of the L-shaped chain plate are respectively attached to the hanger 10 and the first beam 501, and the positioning pin chain 202 and the hanger 10 are fixedly connected by the positioning pin 201, and then the positioning pin 201 is connected to the first beam 501 through the chain.

[0043] The operation steps of the bridge deck combined hanger of the utility model are as follows: when the special hanger is placed on the bridge deck, the hanger 10 moves downward through the four guide columns 601 under the action of gravity, and the first crossbeam 501 moves downward with the hanger 10, and the height of the second crossbeam 502 relative to the bridge deck remains unchanged by adjusting the valve stem 602. Because the second connecting rod 403 is fixed together with the second crossbeam 502 by the pin shaft and can only rotate, the first connecting rod 401 connects the first crossbeam 501 and the second connecting rod 403 together by the pin shaft.

[0044] When the first crossbeam 501 moves downward, it drives the first link 401 and the second link 403 to move, and the second link 403 rotates and opens, driving the fixing plate 80 to move, and when the hanger 10 moves upward, the second link 403 rotates and merges, and the four corners are fine-tuned by adjusting the valve stem 602, so that the round steel at the end of the second link 403 quickly enters the groove reserved on the side of the bridge deck, clamps the groove on the side of the bridge deck, and then fixes the fixing plate 80 with the steel bars on the side of the bridge deck through the fasteners 404.

[0045] The hanger 10 continues to move upward, the bridge deck is lifted and moved to the designated position. The bridge deck is lowered, and the hanger 10 moves to the first beam 501 under the action of gravity, the first connecting rod 401 moves, the second connecting rod 403 rotates and opens, and then the hook 603 is opened and placed on the valve steel 604. The second beam 502 and the first beam 501 remain in an open state and the distance remains unchanged under the action of the hook 603 and the valve steel 604, and finally the hanger 10 is removed.

[0046] In summary, the new bridge deck combination hanger of the embodiment of the utility model can accurately adjust the position relative to the bridge deck to facilitate the rapid fixation of the steel bars and hangers extending from the side of the bridge deck, making the lifting of the bridge deck faster and safer, and better adaptable to bridge decks of different specifications and the requirements of different installation angles at the installation site.

[0047] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
