Description

Technical Field

[0001] The utility model relates to the technical field of crown beam support beam construction, in particular to a tool for quickly grinding the heads of retaining piles. Background Art

[0002] During the construction of crown beam support beams, grinding the pile heads after the retaining piles are removed is often a time-consuming and laborious task. Traditionally, after the pile heads are broken, they are manually ground with a grinder. However, due to the dense rebar within the rebar cage, workers often have difficulty reaching inside the piles for grinding, or have difficulty grinding far away. This often requires workers to stand inside the rebar cage and bend over to grind. This is not only labor-intensive, but the vibrations from grinding can cause numbness in the workers' arms, making fatigue and slipping the grip a high risk, posing a significant threat to their personal safety.

The sleeve 4 and the operating rod 3 are locked and fixed by the locking sleeve 5.

[0035] The tool for quickly grinding the heads of retaining piles using the above-mentioned technical solution is mainly composed of an operating rod 3, a grinder 1, a sleeve 4 and a locking sleeve 5. With the cooperation of the sleeve 4 and the locking sleeve 5, the length of the operating rod 3 can be adjusted or extended, which is convenient for the staff to hold the sleeve 4 and use the grinder 1 to grind the heads of retaining piles at a farther position, avoiding the staff from standing in the steel cage and bending over to grind. It can not only greatly reduce the workload and work intensity, but also effectively avoid the vibration generated during grinding that causes numbness in the staff's arms, effectively avoid fatigue, loss of hands, etc., and provide greater protection for the personal safety of the staff.

[0036] Specifically, in this embodiment, in order to facilitate elastic deformation of the front end wall of the sleeve 4 so that the locking sleeve 5 can lock the front end of the sleeve 4 on the operating rod 3, a plurality of notches 11 are opened on the front end wall of the sleeve 4, and the plurality of notches 11 are arranged at equal angles in a circular direction around the central axis of the sleeve 4.

[0037] In order to improve the operating feel of the locking sleeve 5 , a plurality of anti-slip grooves are integrally provided on the outer surface of the locking sleeve 5 .

[0038] In order to facilitate the staff to operate the tool for quickly grinding the pile heads of retaining piles, a handle 6 is fixedly installed at the rear end of the sleeve 4, and the handle 6 is set in a D shape. By setting the handle 6, it is convenient to control the angle of the grinder 1 to remain unchanged, so as to facilitate the high-quality completion of the operation of grinding the pile heads of retaining piles at a distant position.

[0039] In order to improve safety and reduce the incidence of electric shock accidents, the operating rod 3, sleeve 4, locking sleeve 5 and handle 6 are all made of insulating materials, such as insulating plastic.

[0040] Specifically, in this embodiment, the grinder 1 is fixedly connected to the operating rod 3 by at least two tightened iron wires 2.
