Upper portion girder steel 1 and lower part girder steel 2 are H shaped steel roof beam, and H shaped steel roof beam all includes two about and the relative pterygoid lamina 4 that sets up of level and a web 5 that is located between two pterygoid laminas 4, two pterygoid laminas 4 of 5 perpendicular to of web.
The upper steel beams 1 are two or more and are arranged in parallel at intervals, and the number of the upper steel beams 1 is two in the example. The connecting mechanisms 3 are distributed along the length direction of the upper steel beam 1 in a plurality of numbers, and the connecting mechanisms 3 on each upper steel beam 1 are two in the embodiment. Through 3 sliding connection of coupling mechanism's 1 upper portion girder steel 2 of two or many along the 1 length direction distribution of upper portion girder steel, the quantity of lower part girder steel 2 is two in this embodiment.
Still be provided with wheel components 6 on the girder steel 2 of lower part, wheel components 6 are provided with a plurality ofly along the length direction of girder steel 2 of lower part, have hoist 27 through wheel components 6 lower part girder steel 2 sliding connection.
The connecting mechanism 3 comprises a roller assembly 6 and an abutment 8. The roller assembly 6 comprises at least two rollers 7 and a connecting piece 9 which are arranged coaxially at intervals, and the two rollers 7 which are arranged coaxially form a group. Two gyro wheels 7 in a set are connected through connecting piece 9, and connecting piece 9 includes two relative parallel and interval set up curb plate 10, connects through a mounting rod 11 between two curb plates 10. Each side plate 10 is rotatably connected with a roller 7, and the rollers 7 are arranged on the opposite surfaces of the two side plates 10. In the present embodiment, two rollers 7 are provided on each side plate 10, and two sets of rollers 7 are provided in each sub-roller assembly 6. The axial direction of the roller 7 is vertical to the length direction of the upper steel beam 1 and the lower steel beam 2 connected with the roller.
Further, the rollers 7 in the connecting mechanism 3 are located on both sides of the web 5 of the upper steel beam 1 and abut on the lower one of the flanges 4. The rollers 7 of the roller assemblies 6 arranged on the lower steel beam 2 are positioned on both sides of the web 5 of the lower steel beam 2 and abut against the lower wing plate 4.
In addition, the docking member 8 is a plate fixed to the upper surface of a wing plate 4 located at a higher position in the lower steel beam 2, and the mounting rod 11 penetrates the docking member 8 to connect the upper steel beam 1 and the lower steel beam 2.
Four pairs of roller assemblies 6 are arranged along the length direction of each lower steel beam 2, mounting rods 11 in the roller assemblies 6 on the lower steel beams 2 are connected with hanging pieces 12, and hanging holes 13 are formed in the hanging pieces 12. The hanger 27 comprises a rope member 26 connected to the lower steel beam 2 and a hook 14 connected to the end of the rope member 26, and each hanger 27 is independently provided. Wherein, the two ends of the rope 26 are provided with hooks 14, one hook 14 is used for hanging in the hanging hole 13, and the other hook 14 is used for connecting with the prefabricated member.
So set up, through adjusting relative position between upper portion girder steel 1 and the lower part girder steel 2, adjusting hoist 27 place position to realize that the gallows is connected with not unidimensional prefab. In order to avoid the roller assembly 6 from being separated in the process of moving on the upper steel beam 1 and the lower steel beam 2, the two ends of the upper steel beam 1 and the lower steel beam 2 are provided with limiting parts 15, and the limiting parts 15 are sheet bodies arranged in the notch area defined by the two wing plates 4 and the web plate 5.

The thrust block 17 is a wedge-shaped block, and a magnet block (not shown) is arranged in the thrust block 17.
This is so arranged that the thrust block 17 is wedge-shaped and has its sharp end directed towards the roller 7, so that it can be easily snapped between the roller 7 and the wing 4 to position the roller assembly 6. Because the magnet block is arranged in the thrust block 17, the thrust block 17 can be conveniently and fixedly adsorbed on the upper steel beam 1 and the lower steel beam 2.
In addition, because every pair of hoist 27 all is independent setting, so can be relatively easily adjust hoist 27 to suitable position, after utilizing stop gear 16 to fix the position of hoist 27, can make hoist 27 all be perpendicular for lower part girder steel 2 when being connected with the prefab, and then make the hoist in the in-process of transporting the prefab, the prefab can keep the level. Finally, the problem that the corners of the prefabricated member are broken and the quality of the prefabricated member is affected due to the fact that the single corners are in contact with the ground in the lifting process of the prefabricated member is avoided as much as possible.
The implementation principle of the embodiment is as follows: because lower steel beam 2 can move along the length direction of upper steel beam 1, and hoist 27 on lower steel beam 2 can also move along the length direction of lower steel beam 2, hoist 27 can infinitely adjust to arbitrary position on the hoist, thereby can be connected with the prefabricated member of multiple sizes.
After the upper steel beam 1 and the lower steel beam 2 are adjusted to the proper positions and the spreader 27 is also adjusted to the proper positions. The roller assembly 6 is locked by the limiting mechanism 16, so that the prefabricated part can be stably hung and conveyed by the hanging frame.
Example two:
as shown in fig. 3 and 5, compared with the first embodiment, the hanger for producing concrete members is characterized in that the web 5 of the upper steel beam 1 and the lower steel beam 2 is provided with a through hole 18 extending along the length direction thereof, the limiting mechanism 16 comprises a connecting member 9, the connecting member 9 is a rod member passing through the through hole 18, and the connecting member 9 is coaxially connected with the rollers 7 at both sides of the web 5.
The connecting piece 9 comprises a rotating shaft 19 which is coaxially and rotatably connected with each roller 7, the outer diameter of the rotating shaft 19 is larger than the height of the through opening 18, and the two rotating shafts 19 in the same group of roller assemblies 6 are coaxially positioned on two sides of the web 5. A coaxial hole 20 is formed in each rotating shaft 19, a rotating threaded sleeve 21 and a locking bolt 22 are arranged in the coaxial hole 20, and a hexagonal block-shaped limiting ring 23 is coaxially arranged at one end of the rotating threaded sleeve 21. The rotating screw sleeve 21 passes through one rotating shaft 19 and the through opening 18 relative to the end part of one end provided with the limiting ring 23 and then extends into the coaxial hole 20 of the other rotating screw sleeve 21, and the locking bolt 22 passes through the coaxial hole 20 of one rotating shaft 19 and is coaxially screwed with the rotating screw sleeve 21. Installation pole 11 is connected on spacing ring 23 and with the coaxial setting of rotation swivel nut 21, and interfacing part 8 is for fixing the plate body on the pterygoid lamina 4 upper surface that is in higher position in lower part girder steel 2, and installation pole 11 passes interfacing part 8 and rotates with interfacing part 8 and be connected to realize being connected of upper portion girder steel 1 and lower part girder steel 2.
Through so setting up, the bolt head and the spacing ring 23 of holding locking bolt 22 are held between the hands, revolve locking bolt 22 to rotatory swivel nut 21, are located two axis of rotation 19 that just are located web 5 both sides between the bolt head of spacing ring 23 and locking bolt 22 and are close to each other. Because the rotation axis 19 can not pass through the through opening 18, the opposite ends of the two rotation axes 19 tightly abut against the webs 5 at the two sides of the through opening 18, thereby realizing the locking and limiting of the roller assembly 6, and ensuring that the roller assembly 6 can not move along the length direction of the upper steel beam 1 and the lower steel beam 2. The roller wheel assembly 6 is fixed on the upper steel beam 1 and the lower steel beam 2, and then the upper steel beam 1 and the lower steel beam 2 are relatively fixed, and the lower steel beam 2 and the roller wheel 7 are relatively fixed by the hanger 27.
