Device for free-angle drilling

Abstract

The invention discloses a device capable of drilling holes at free angles. The device comprises a supporting portion at the bottom, an angle adjusting portion arranged on the supporting portion and a drilling portion arranged on the angle adjusting portion. The supporting portion is used for supporting the angle adjusting portion and the drilling portion, and the height of the supporting portion is adjustable; the angle adjusting portion can adjust the drilling direction of the drilling portion and can enable the drilling portion to drill holes at any angle; and the drilling portion can carry out drilling operation at the set angle under the effect of the angle adjusting portion. The device is simple in whole structure, convenient to assemble and disassemble and capable of drilling holes at any angle.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a device for free-angle drilling at high places of structures such as reinforced concrete wall columns and roof plates. Background technique [0002] The "rebar planting" technology is widely used in the anchorage of the secondary structural wall tension bars, the fixing of the embedded parts of the curtain wall structure and the fixing of the foundation bolts of the industrial plant equipment, etc. Before planting bars, you must first drill holes. When drilling at low places, you can use an electric drill to drill directly. There is no difficulty in operation and the safety risk is small. When drilling in all directions at a higher place in the reinforced concrete structure , due to the high superstructure and the effect of gravity, it brings a lot of inconvenience to the construction, such as: (1) people have to build a shelf or ladder for high-altitude operations, which in...

Problems solved by technology

Before planting bars, you must first drill holes. When drilling at low places, you can use an electric drill to drill directly. There is no difficulty in operation and the safety risk is small. When drilling in all directions at a higher place in the reinforced concrete structure , due to the high superstructure and the effect of gravity, it brings a lot of inconvenience to the construction, such as: (1) people have to build a shelf or ladder for high-altitude operations, which increases the difficulty of construction and safety risks; (2) it is necessary to frequently move the shelf or The ladder is inconvenient for construction, the drilling efficiency is low, and the labor cost is increased; (3) The force used for drilling plus the gravity of the electric drill makes the drilling operation extremely laborious
