Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an electric bolt fastening device for installing air ducts in shear wall shafts. Background Technology

[0002] In high-rise and super high-rise buildings, frame-shear wall structures are widely used due to their flexible floor plan, large spatial capacity, and high lateral stiffness. In ventilation and air conditioning sub-projects, pressurized air supply ducts and smoke exhaust ducts in the smoke control and exhaust systems are often installed close to the shear walls. However, the gap between the ducts and the shear walls is narrow. When the duct cross-sectional side length is greater than 500mm, it is impossible to reach the bolts by hand for tightening during installation, resulting in loose duct connections, air leakage, failure to meet construction quality acceptance requirements, and impacting the main functional use of the ducts.

The main boom 6 is hollow inside and rotatably mounted with a rotating shaft 4. The first end of the rotating shaft 4 is provided with a hand drill 9 for driving the rotating shaft 4 to rotate. The bolt head sleeve 1 is rotatably disposed on one side of the main boom 5, and the rotation direction of the bolt head sleeve 1 is perpendicular to the rotation direction of the rotating shaft 4. The secondary boom 6 is rotatably connected to the main boom 5, and the nut sleeve 2 is fixedly connected to one end of the secondary boom 6, and the nut sleeve 2 is located directly above the bolt head sleeve 1. The gear set 11 is used to synchronously transmit the rotational motion of the rotating shaft 4 to the bolt head sleeve 1, and the gear set 11 is disposed between the bolt head sleeve 1 and the second end of the rotating shaft 4.

[0025] Furthermore, in this embodiment, the gear set 11 includes two gears that are vertically arranged and mesh with each other. Preferably, a gear box 3 is fixedly connected between the bolt head sleeve 1 and the main arm 5, and both gears are located inside the gear box 3. It should be noted that in this embodiment, a connecting rod 13 is fixedly connected to the bottom of the bolt head sleeve 1. The end of the connecting rod 13 facing away from the bolt head sleeve 1 extends into the gear box 3 and is coaxially connected to one of the gears. The second end of the rotating shaft 4 extends into the gear box 3 and is coaxially connected to the other gear. Bearings 10 are installed on the sidewalls of the gear box 3 corresponding to the positions of the connecting rod 13 and the rotating shaft 4. Under the action of the bearings 10, the connecting rod 13 and the rotating shaft 4 can rotate relative to the gear box 3.

The main boom 5 adopts an outer diameter specification of... The outer diameter of the circular tube and the rotating shaft 4 is as follows: By setting up the boom support 7 and ensuring that the main boom 5 and the auxiliary boom 6 always remain on the same vertical plane, the auxiliary boom 6 can rotate up and down flexibly (the auxiliary boom 6 and the boom support 7 are connected by a pin, so that the auxiliary boom 6 can rotate relative to the boom support 7), thereby allowing the bolt head sleeve 1 and the nut sleeve 2 to separate and close. Preferably, a handle sleeve 8 is fitted on the side of the auxiliary boom 6 that is relatively far from the nut sleeve 2 and on the side of the main boom 1 that is relatively close to the electric drill 9, so as to facilitate comfortable gripping by the user.

The specification of both the bolt head sleeve 1 and the nut sleeve 2 is S=13mm. Magnets are installed inside both the bolt head sleeve 1 and the nut sleeve 2 to stabilize the duct bolt 14 and the duct nut 15. The first end of the rotating shaft 4 extends out of the main boom 1 and is fixedly connected to a connecting bolt 12 for use with the electric drill 9. In this embodiment, the connecting bolt 12 is a hexagonal head bolt. The rotating shaft 4 is driven to rotate by the electric drill 9, which in turn drives the bolt head sleeve 1 to rotate through the gear set 11, and finally the rotation of the duct bolt 14 is used to cooperate with the duct nut 15 to achieve a fastening effect.
