Wherein, the triangular scaffold body 2 pulls the lifting ring 5 to horizontally pull and send the steel roof beam 1 of being transported to the sliding steel pipe slope conveying mechanism by the manual hoist 4 connected on it. The sliding steel pipe slope conveying mechanism is located between the bottom of the reserved hole to the indoor ground, and is used for sliding the steel roof beam 1 of being transported from the reserved hole to the indoor ground, and the I -steel portal 7 pulls the lifting ring 5 to realize the horizontal displacement of the steel roof beam 1 on the indoor ground by the manual hoist 4 connected on it.

The bottom of the lower flange plate of the steel roof beam 1 (the steel roof beam of needing horizontal transportation) is provided with the sliding steel pipe 3, and the sliding steel pipe 3 provides a good transport platform for the steel roof beam, which can avoid horizontal dragging and transporting the steel roof beam 3 directly on the ground, and the sliding steel pipe 3 can improve the horizontal transportation efficiency of the steel roof beam.
[0029] The anchor bolt of the utility model includes the bolt 8 of being threaded into the bolt hole of the four corner portions of the iron sheet connecting piece 6 and the upper flange plate of the steel roof beam 1 to be transported, and the nut of being screwed with the bolt 8 and being located at the bottom of the upper flange plate of the steel roof beam 1 to be transported. The iron sheet connecting piece 6 on the upper flange plate of the steel roof beam 1 to be transported is connected and stabilized by the nut and the bolt 8. The bolt 8 is threaded into the reserved hole on the iron sheet connecting piece 6 and the upper flange plate of the steel roof beam 1 to be transported, and the other end of the bolt 8 is screwed with the matched nut to fix and connect the iron sheet connecting piece 6 and the steel roof beam 1 to be transported.
[0030] The steel roof beam 1 to be transported is lifted and transferred to the vicinity of the reserved small -size hole by the crane, and the spatial orientation of the steel roof beam is adjusted manually, so that the steel roof beam is substantially perpendicular to the wall surface of the reserved hole and enters the hole. The steel roof beam is first placed on the hole platform surface.
[0031] The iron plate connecting piece 6 is a factory prefabricated iron plate piece with a thickness of 20 mm. The lifting ring 5 connected to the iron plate connecting piece 6 comprises a perforated iron plate 51 fixedly connected to the top surface of the iron plate connecting piece 6 and arranged vertically thereto, and a perforated U-shaped stainless steel round bar 52, and a pin 53 is inserted through the perforated iron plate 51 and the perforated U-shaped stainless steel round bar 52 to connect the perforated U-shaped stainless steel round bar 52 and the perforated iron plate 51. One end of the pin 53 has a diameter larger than the through hole at the end of the perforated U-shaped stainless steel round bar 52, and the other end of the pin 53 has external threads, and the through hole at the end of the perforated U-shaped stainless steel round bar 52 has internal threads for screwing with the external threads, and the pin 53 is screwed into the perforated U-shaped stainless steel round bar 52 to form an effective fixed connection. The lifting ring 5 can be connected to the manual hoist 4 and the crane. The crane hoists the steel beam 1 to be transported to the reserved hole, and adjusts the spatial position of the steel beam 1 to be transported to be perpendicular to the wall surface of the reserved hole, and then delivers it to the position of the triangular scaffold body 2 close to the wall surface of the reserved hole on the indoor side of the reserved hole.
[0032] The triangular scaffold body 2 is erected close to the wall surface of the reserved hole on the indoor side of the reserved hole. The manual hoist 4 is arranged on the triangular scaffold body 2, and the hook of the manual hoist 4 is connected to the lifting ring 5 of the iron plate connecting piece 6 on the steel beam 1 to be transported to pull the steel beam.

The distance between the sliding steel pipes 3 on the sliding steel pipe slope conveying mechanism is 100 mm, and the slope of the inclined surface of the triangular frame body 9 is 20-30 degrees. The steel beam 1 to be transported is always pulled by the manual hoist 4 on the triangular scaffold body 2 until the steel beam 1 to be transported is smoothly moved to the sliding steel pipes 3 on the horizontal ground.
[0034] After the manual hoist 4 arranged on the triangular scaffold body 2 pulls the steel beam 1 to be transported into position, the manual hoist 4 is moved to the sliding steel pipe slope conveying mechanism, and the manual hoist 4 on the triangular scaffold body 2 pulls the lifting ring 5 on the steel beam 1 to be transported to realize the displacement of the steel beam 1 to be transported on the sliding steel pipe slope conveying mechanism.

[0039] (2) An iron plate connector 6 is set at the corresponding position of the upper flange plate of the steel beam 1 to be transported. The iron plate connector 6 is connected to the steel beam 1 to be transported by an anchor bolt. The position of the iron plate connector 6 set on the upper flange plate of the steel beam 1 to be transported can meet the requirements of crane lifting (the iron plate connector 6 is set at the middle position of the end of the total length of 1 / 4-1-3 of the steel beam 1 to be transported), which can ensure that the steel beam 1 to be transported can be safely transported to the reserved opening. At the same time, the position of the iron plate connector 6 can be conveniently connected to the manual hoist 4 on the triangular scaffolding body 2 erected indoors.
[0040] (3) When the steel beam 1 to be transported is delivered to the room with the reserved opening by the outdoor crane, the manual hoist 4 provided on the triangular scaffolding body 2 is immediately connected to the lifting ring 5 on the iron plate connector 6 of the steel beam 1 to be transported, and the manual hoist 4 is slowly pulled to move the steel beam 1 to be transported onto the sliding steel pipe 3 of the sliding steel pipe slope transmission mechanism, and the steel beam 1 to be transported is slowly pulled to the sliding steel pipe 3 on the horizontal ground indoors.
[0041] (4) the manual hoist 4 on the I-shaped steel portal 7 is connected with the lifting ring 5 on the iron plate connecting piece 6 of the steel beam 1 to be transported, and slowly pulls the steel beam 1 to be transported on the sliding steel pipe 3 on the indoor horizontal ground to the target position. In this way, the target of transporting the steel beam indoors horizontally through the small hole reserved in the side wall outdoors is achieved.
[0042] The above merely describes specific implementation manners of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can understand the transformation or replacement within the technical range disclosed by the present application, and the transformation or replacement should be covered in the inclusive scope of the present application.
