[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] This embodiment provides an electric rebar sleeve connection device, such as... Figures 1-4 As shown, the device includes a metal protective cover 4 and a continuously variable speed motor 1 housed within the metal protective cover 4. The metal protective cover 4 covers the critical parts of the equipment, preventing damage to these parts and avoiding worker contact with them, thus improving safety. The continuously variable speed motor 1 has a power of 0.75KW and an adjustable speed range of 40-200r / m. The continuously variable speed motor 1 transmits torque through a gearbox. It also includes a tightening mechanism connected to the continuously variable speed motor 1. The continuously variable speed motor 1 drives the tightening mechanism to rotate forward or backward. The tightening mechanism is used to clamp the reinforcing bar. After clamping the reinforcing bar, the tightening mechanism rotates, screwing the reinforcing bar into the reinforcing bar sleeve 16.

[0021] The output shaft of the continuously variable speed motor 1 is fixedly connected to the universal joint coupling 2. The continuously variable speed motor 1 drives the universal joint coupling 2 to rotate, and the universal joint coupling 2 drives the adaptive rebar wrench 5 to rotate via the robotic arm 3. The continuously variable speed motor 1 is equipped with a forward rotation button 6 and a reverse rotation button 7. The forward rotation button 6 controls the continuously variable speed motor 1 to rotate forward, thereby driving the adaptive rebar wrench 5 to rotate forward; the reverse rotation button 7 controls the continuously variable speed motor 1 to rotate in reverse, thereby driving the adaptive rebar wrench 5 to rotate in reverse.

[0022] The stepless speed-regulating motor 1 is also equipped with a three-phase emergency stop button 8. In an emergency, the three-phase emergency stop button 8 can cut off the power supply to the stepless speed-regulating motor 1, and the equipment will stop working. The stepless speed-regulating motor 1 is also equipped with a power switch 11 and a power cord connector 12. The power cord connector 12 is used to connect to an external power source, and the power switch 11 is used to control the start and stop of the stepless speed-regulating motor 1.

[0023] Two handles 9 are fixedly provided on the metal protective cover 4, and several wheels 10 are provided at the bottom for rotation. By pulling the metal protective cover 4 through the handles 9, the wheels 10 are driven, making it easy to move the metal protective cover 4. The metal protective cover 4 is also provided with a heat dissipation duct 13, which is used to dissipate heat for the stepless speed regulating motor 1.

[0024] The screwing mechanism includes a universal joint coupling 2, a robotic arm 3, and an adaptive rebar wrench 5. One end of the robotic arm 3 is connected to the universal joint coupling 2, and the other end is connected to the adaptive rebar wrench 5. The arm span of the robotic arm 3 is no more than 0.5m. The adaptive rebar wrench 5 is used to clamp the rebar and can be adapted to rebar sleeves 16 with a diameter of no more than 40mm.

[0025] The equipment features a modular design, allowing for quick replacement of faulty components.

[0026] When using, such as Figure 5 As shown, first screw the first reinforcing bar 14 and the second reinforcing bar 15 into the reinforcing bar sleeve 16 from both ends by 2-3 threads, then fix the other end of the second reinforcing bar 15 with an external wrench 17. Figure 6 As shown, the outer end of the first rebar 14 is clamped using the adaptive rebar wrench 5. Depending on the direction of the internal threads of the rebar sleeve 16, the forward rotation button 6 or the reverse rotation button 7 is pressed to start the stepless speed-regulating motor 1. The stepless speed-regulating motor 1 drives the universal joint coupling 2 to rotate. The universal joint coupling 2, through the robotic arm 3, drives the adaptive rebar wrench 5 to rotate, causing the first rebar 14 to rotate and screw it into the rebar sleeve 16. Practical verification has shown that the time to connect a single rebar can be shortened to 30 seconds, increasing efficiency by 500%.

[0027] like Figure 7 As shown, after the first reinforcing bar 14 and the reinforcing bar sleeve 16 are tightly connected, there is no relative rotation between them. When the first reinforcing bar 14 rotates, it drives the reinforcing bar sleeve 16 to rotate. Since the end of the second reinforcing bar 15 is fixed by the external wrench 17 and cannot rotate, the rotating reinforcing bar sleeve 16 fits the second reinforcing bar 15 into it, thus completing the connection of the second reinforcing bar 15. After the two reinforcing bars are connected, release the forward rotation button 6 or the reverse rotation button 7.

[0028] This equipment replaces manual operation with motor drive, significantly improving the connection efficiency of rebar and sleeve and ensuring connection quality; a metal protective cover 4 covers key parts of the equipment, improving its safety; the modular design facilitates maintenance and component replacement; the telescopic robotic arm and adjustable adaptive rebar wrench are suitable for connecting common specifications of rebar and sleeve, improving the equipment's adaptability; the equipment is simple to operate, easy to implement, and low in cost, which helps control costs.

[0029] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, as long as the changes or modifications do not deviate from the technical solution of the present application.
