Problems solved by technology
[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a steel bar connection and rotating device used in construction engineering to solve the problem of manually using pipe wrench to rotate the steel bars when installing and connecting the steel bars with the steel bar sleeve. The threaded joint of the head and the steel bar sleeve often have the problem of tolerance fit, the connection is particularly laborious, the efficiency is extremely low, and one person cannot operate at all; in addition, during the construction on site, since the steel bar is added to the original steel bar, especially the pile The steel bars on the column have a relatively high density. Due to the space environment, it is impossible to use pipe wrench to rotate the steel bars.

Embodiment
[0032] Such as Figure 1-7 As shown, the present invention is a steel bar connection rotating device used in construction engineering, including an open inner gear ring 1, a sliding clamp block 2, a planetary gear 3, a driving motor 4, an upper steel bar clamping device 5 and a lower steel bar clamping device 6. One side of the open inner gear ring 1 is provided with a break opening 8 that can pass through the steel bar sleeve 7. Through the break open 8, the open inner gear ring 1 can directly pass through the steel bar sleeve 7 and be set on the steel bar. On the periphery of the sleeve 7, since the steel bar is generally several meters in length, it is inconvenient to insert from both ends of the steel bar, ring protrusions 9 are provided on the two ring sides of the open internal gear ring 1, and ring protrusions 9 are provided on the outer ring surface of the ring protrusion 9. There is a ring groove 10, and the upper fan-shaped sliding clamp block 11 and the lower fan-sh...

The invention discloses a steel bar connecting and rotating device for constructional engineering. Annular protrusions are arranged on the two annular side faces of an open inner gear ring, and annular grooves are formed in the outer annular faces of the annular protrusions. The sliding clamping blocks comprise an upper fan-shaped sliding clamping block and a lower fan-shaped sliding clamping block; the upper fan-shaped sliding clamping block and the lower fan-shaped sliding clamping block are correspondingly buckled on the upper side surface and the lower side surface of the open inner gear ring; planetary gears in meshed connection with the gear rings in the opening are arranged in cavities in the two ends of the sliding clamping block correspondingly. The planetary gears are correspondingly mounted on the upper fan-shaped sliding clamping block and the lower fan-shaped sliding clamping block through gear shafts; a planetary chain wheel is arranged on the gear shaft penetrating through the upper fan-shaped sliding clamping block; a driving motor is arranged in a cavity in the middle of the sliding clamping block, a motor chain wheel is arranged on a rotating shaft of the drivingmotor, the motor chain wheel is in transmission connection with the corresponding planetary chain wheel through a chain, the driving motor synchronously drives two planetary gears to rotate through the chain, and the two planetary gears are meshed with inner teeth of an opening inner gear ring.
Description
technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to a steel bar connection rotating device used in construction engineering. Background technique [0002] In the field of construction engineering construction, rib stripping and rolling straight thread connection of steel bar is a relatively mature steel sleeve technology. Its structural principle is to peel off part of the longitudinal rib and transverse rib at the end of the steel bar to be connected by cutting. Then it is directly rolled into ordinary straight thread, and then connected with special straight thread steel bar sleeve to form the connection of steel bar. [0003] In order to save processing costs, the steel bar sleeve generally adopts a cylindrical structure, and the steel bar is also a cylindrical structure, so when installing and connecting, generally use a pipe wrench to turn the steel bar manually, because the threaded joint at the en...
