Background

At present, the country advocates extensively to develop the prefabricated building widely, and the operation of assembled steel structure is born, and nevertheless the connection of medium-sized steel column and concrete foundation concrete of steel construction engineering still connects through pre-buried rag bolt in the basis, because rag bolt's length is about 1 meter, and the manual installation rag bolt nut efficiency is low, also is difficult to screw up.

Disclosure of Invention

The utility model discloses a solve present rag bolt upper nut and adopt artifical installation to have the poor and inefficiency problem of installation effect, provide an electronic installation device of shaped steel post rag bolt upper nut.

The utility model discloses an adopt following technical scheme to realize: an electric mounting device for nuts on foundation bolts of section steel columns comprises an electric wrench and a steering transmission mechanism, wherein an inner hexagonal sleeve with an opening facing to the left is arranged at the power end of the electric wrench, a connecting plate fixed on the electric wrench is arranged on the right side of the inner hexagonal sleeve, and a connecting hole is formed in the lower portion of the connecting plate; the steering transmission mechanism comprises a bearing sleeved on the foundation bolt, a bottom plate fixed with an outer ring of the bearing is arranged on the right side of the bearing, a connecting rod penetrating into the connecting hole is fixed at the right end of the bottom plate, a supporting plate is fixed on the upper end face of the bottom plate, a transmission rod penetrates through the supporting plate, a vertically-arranged driving bevel gear is arranged at the left end of the transmission rod, and a hexagon nut matched with the inner hexagon sleeve is arranged at the right end of the transmission rod; the upper end of the bearing inner ring is fixed with a driven bevel gear meshed with the driving bevel gear, and the lower end of the bearing inner ring is fixed with a nut cutting sleeve.

When the nut of the foundation bolt is installed, the nut is firstly sleeved on the nut in a clamping way, then the switch of the electric wrench is started, the inner hexagonal sleeve is driven, the hexagonal nut, the transmission rod and the driving bevel gear are driven to rotate, and then the driven bevel gear, the bearing inner ring, the nut clamping sleeve and the nut are driven to rotate in a turning way, so that the nut is automatically screwed on the foundation bolt, after the nut reaches the design position, the electric wrench is closed, the nut is installed on the steel column foundation bolt, and the problems that the installation effect is poor and the efficiency is low due to the fact that the existing nut on the foundation bolt is installed manually are solved.

The nut cutting ferrule includes that the upside internal diameter is less than the annular sleeve pipe of downside internal diameter, and annular sleeve pipe's lateral wall equipartition is opened has the strip hole of a plurality of vertical settings, has worn the screw rod in the strip hole, and the outer tip of screw rod has all been twisted lock nut who hugs closely annular sleeve pipe lateral wall, and the inner of screw rod all is connected with the wedge fixture block of hugging closely the annular sleeve inside wall.

When the nut clamping sleeve is used for installing the nut on the foundation bolt, the annular sleeve is firstly sleeved on the nut, then the wedge-shaped fixture block is adjusted up and down until the wedge-shaped fixture block is tightly attached to the nut, the wedge-shaped fixture block is fixed through the locking nut, and the nut clamping sleeve is installed on nuts with different sizes.

The utility model has the advantages of reasonable design reliably, realized the electronic installation of rag bolt upper nut, the installation dynamics is even, avoids rag bolt screw thread to damage, and nut installation accuracy obtains promoting by a wide margin, has saved the process that artifical manual spanner screwed the nut moreover, has improved the efficiency of construction when reducing intensity of labour, is applicable to the installation of different specification rag bolt upper nuts, has simple structure, convenient operation, wide and repeatedly usable's advantage of using face.
