Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an electric screw wrench for deep processing of steel structures. Background Technology

[0002] Steel structure construction is a relatively common structural form, with significant advantages in terms of strength, seismic performance, construction speed, and environmental protection. Using construction tools such as electric screwdrivers can effectively improve construction quality and efficiency.

[0003] A search revealed Chinese patent CN208854523U, which discloses an electric wrench. The wrench includes a wrench body and a bolt sleeve located at the rotating output end of the wrench body. It also includes a telescopic rod, one end of which is connected to the rotating output end of the wrench body, and the other end of which is detachably connected to the bolt sleeve. The telescopic rod includes a sleeve, one open end of which is connected to a sleeve connector for connection to the rotating output end of the wrench body. A mandrel is fitted onto the outer surface of the sleeve through the other open end, and the end of the mandrel away from the sleeve is connected to the sleeve connector. A positioning screw hole is provided through the outer surface of the sleeve at a position away from the sleeve connector, and a locking nut is provided in the positioning screw hole. This utility model provides an electric wrench that allows railway workers to tighten high-strength bolts without bending over by adjusting the length of the telescopic rod, saving time and effort and improving efficiency.

[0004] Based on the above retrieval methods combined with existing technologies;

[0005] The aforementioned patents have certain limitations due to the difficulty of construction caused by insufficient installation space at corners, resulting in bolts that cannot be tightened. Furthermore, the types of drill bits are fixed and cannot be changed according to actual installation needs, leading to poor practicality. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes an electric screw wrench for steel structure deepening, which ensures construction quality and structural safety while accelerating the construction progress.

[0007] The technical solution to achieve the purpose of this utility model is: an electric screw wrench for deep drilling of steel structures, including a base, and further comprising;

[0008] The handle is fixedly mounted on the surface of the base;

[0009] An electric drill rig, which is fixedly mounted on the top of the handle.

[0010] Preferably, a switch is fixedly installed on the side of the handle, and a rubber anti-slip pad is fixedly installed on the side of the handle, with the switch positioned above the rubber anti-slip pad.

[0011] Preferably, an electric telescopic rod is fixedly installed on one side of the electric drilling rig, and a ball cage type constant velocity universal joint coupling is fixedly installed at one end of the electric telescopic rod. A drill bit is fixedly installed on the ball cage type constant velocity universal joint coupling.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model can be used in smaller spaces and with an electric wrench, enhancing its practicality, ensuring construction quality and structural safety, and accelerating the construction progress.

[0014] Secondly, this utility model uses a ball cage type constant velocity universal coupling, which can achieve completely constant velocity transmission, suppress the adverse effects of various vibrations and impacts on related equipment caused by changes in speed and torque, and has high transmission efficiency, compact structure, small space occupation, simple structure, easy operation, saves labor, and improves construction efficiency.

[0015] This solves the problems of existing construction methods, such as difficulty in construction due to insufficient installation space at corners, resulting in bolts not being able to be tightened, and the fixed type of drill bit that cannot be changed according to actual installation needs, leading to poor practicality.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved electric screwdriver for deep-working steel structures. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, an electric screw wrench for steel structure deepening includes a base 1, which provides assistance for the operation of the equipment, and also includes;

[0025] Handle 2 is fixedly installed on the surface of base 1, which is conducive to workers' gripping and operation;

[0026] The electric drill rig 4 is fixedly installed on the top of the handle 2 to ensure construction quality and structural safety, and to speed up the construction progress.

[0027] Furthermore, a switch 3 is fixedly installed on the side of the handle 2, and a rubber anti-slip pad 8 is fixedly installed on the side of the handle 2. The switch 3 is located above the rubber anti-slip pad 8. The addition of the rubber pad increases friction and prevents it from falling off.

[0028] Furthermore, an electric telescopic rod 5 is fixedly installed on one side of the electric drilling rig 4, and a ball-cage type constant velocity universal joint coupling 6 is fixedly installed at one end of the electric telescopic rod 5. A drill bit 7 is fixedly installed on the ball-cage type constant velocity universal joint coupling 6, which can suppress the adverse effects of various vibrations and impacts on related equipment caused by changes in rotational speed and torque. It also has high transmission efficiency, compact structure, and small space occupation.

[0029] The specific working method is as follows: the worker holds the handle 2 and starts the electric drill 4. For construction sites with different angles, the angle of rotation torque is adjusted through the ball cage type constant velocity universal joint coupling 6 to achieve the effect of tightening the bolts on the side. If the length is insufficient, the electric telescopic rod 5 can be used to reach the required length. The drill bit 7 can be replaced and can be freely replaced with electric drills, screwdrivers, wrenches, etc. according to the usage scenario, making it highly practical.

[0030] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
