[0024] As shown in Figure 1-2, a steel sleeve installation drive device includes:

[0025] The power mechanism 2 is used to provide rotational power. The output end of the power mechanism 2 is connected to the transmission shaft 3. The transmission shaft 3 is provided with a torque meter 4. The torque meter 4 is used to monitor the torque size when the transmission shaft 3 rotates.

[0026] A first chuck 5 is provided at the end of the transmission shaft 3, and the first chuck 5 is used to fix the steel sleeve; the power mechanism 2 is a motor, which drives the transmission shaft 3 to rotate; the power mechanism 2 can also be a fuel engine.

[0027] The base, the power mechanism 2 is arranged on the base; the bracket assembly, the bracket assembly includes an adjusting rod 12 and a bracket 13, one end of the adjusting rod 12 is fixed to the base, and the other end of the adjusting rod 12 is fixedly connected to the bracket 13, and a positioning hole is provided on the bracket 13, the positioning hole is coaxially arranged with the chuck, and the steel bar passes through the positioning hole and is fixed in the positioning hole. A screw is tightened around the periphery of the positioning hole on the bracket 13, and when the steel bar passes through the positioning hole, the screw is screwed so that the screw presses against the steel bar to achieve the steel bar being fixed in the positioning hole; alternatively, a telescopic rod is provided around the periphery of the positioning hole on the bracket 13, and a pressure block is provided at the end of the telescopic rod; when the steel bar passes through the positioning hole, the telescopic rod is controlled to extend so that the pressure block at the end of the telescopic rod presses against the steel bar, and the pressure block can increase the contact area with the steel bar, so that the steel bar is more firmly fixed in the positioning hole.

[0028] In this driving device, the steel sleeve is fixed on the chuck, the steel bar is fixed in the positioning hole of the bracket 13, and the threaded end of the steel bar is aligned with the steel sleeve. The power mechanism 2 then drives the steel sleeve to rotate, thereby fixing the steel bar at one end of the steel sleeve. During this process, the value of the torque meter 4 is observed in real time. When the torque meter 4 displays a value within the tightening value range, the power mechanism 2 can be shut down. The torque value of the connection between the steel bar and the steel sleeve is monitored in real time by the torque meter 4 to ensure that the steel bar and the steel sleeve can achieve optimal docking stability.

[0029] A positioning seat 6 is further provided on one side of the base, and a transmission cylinder 8 is rotatably provided in the positioning seat 6. The transmission cylinder 8 is connected to the transmission shaft 3 through a belt 9, and the transmission cylinder 8 is used to fix the steel bars.

[0030] The transmission cylinder 8 and the transmission shaft 3 are connected by a belt 9, so that the power mechanism 2 can simultaneously drive the transmission shaft 3 and the transmission cylinder 8 to rotate, that is, the transmission shaft 3 station and the transmission cylinder 8 station can work at the same time, so that the steel sleeve installation drive device can simultaneously perform installation and drive operations on two steel sleeves, greatly improving the operating efficiency of the drive device.

[0031] Screws are tightened on the periphery of the transmission cylinder 8. When the steel bar passes through the transmission cylinder 8, the screws are tightened to press the screws against the steel bar to fix the steel bar in the transmission cylinder 8; alternatively, a telescopic rod is provided on the periphery of the transmission cylinder 8, and a pressure block is provided at the end of the telescopic rod; when the steel bar passes through the transmission cylinder 8, the telescopic rod is controlled to extend so that the pressure block at the end of the telescopic rod presses against the steel bar. The pressure block can increase the contact area with the steel bar, so that the steel bar is more firmly fixed in the transmission cylinder 8.

[0032] A cantilever rod 10 is connected to the positioning seat 6 , and a second chuck 11 is fixed to the end of the cantilever rod 10 . The second chuck 11 is used to fix the steel sleeve. The second chuck 11 is coaxially arranged with the transmission cylinder 8 .

[0033] First, fix the steel bar sleeve on the first chuck 5, fix a steel bar in the positioning hole of the bracket 13, start the power mechanism 2, drive the transmission shaft 3 to rotate, so that the steel bar is installed on one end of the steel bar sleeve; then remove the steel bar and the steel bar sleeve from the first chuck 5, and fix the steel bar sleeve connected to a steel bar on the second chuck 11, and fix the other steel bar in the transmission cylinder 8 at the same time; at this time, the next steel bar sleeve can be fixed on the first chuck 5, and the next steel bar can be fixed in the positioning hole of the bracket 13; start the power mechanism 2, drive the transmission cylinder 8 to rotate through the belt 9, so that another steel bar is fixed to the other end of the steel bar sleeve on the second chuck 11, thereby achieving fixed connection of the steel bars at both ends of the steel bar sleeve. The above entire process is completed under the monitoring of the torque meter 4, ensuring that the steel bar and the steel bar sleeve can achieve optimal docking stability.

[0034] Both the adjusting rod 12 and the cantilever rod 10 are telescopic damping rods. Since both are telescopic damping rods, they can both telescope and move. When the rebar is threadedly connected to the rebar sleeve, the end of the rebar enters the rebar sleeve. During this process, the adjusting rod 12 and the cantilever rod 10 shorten to accommodate this axial displacement of the rebar end entering the rebar sleeve. This facilitates a more stable and reliable connection between the rebar and the rebar sleeve.

[0035] The bracket assembly includes two adjusting rods 12 , which are respectively arranged on both sides of the base. One end of the two adjusting rods 12 is fixed to the base, and the other end is fixed to the bracket 13 , which is located between the two adjusting rods 12 .

[0036] Two adjusting rods 12 are provided to support the bracket 13 from both ends respectively, thereby ensuring that the entire bracket assembly is more evenly stressed and has a longer service life.

[0037] The driving device further includes a support plate 1 , and a plurality of pulleys are arranged below the support plate 1 ; one end of the base is hingedly arranged on the support plate 1 .

[0038] The driving device is provided with a support plate 1 and a pulley, which can make it easier to move the driving device so that the driving device can be moved to any place where it is needed.

[0039] When the first chuck 5, the second chuck 11 and the bracket 13 need to be operated, the base is rotatably set on the support plate 1 so that the base can rotate based on the support plate 1, thereby tilting the entire power mechanism 2 at a certain angle, which is more convenient for the operation of the installed drive device.

[0040] A hydraulic rod 16 is provided at the bottom of the support plate 1 . The hydraulic rod 16 is provided away from the hinged end of the base. The output shaft of the hydraulic rod 16 passes through the support plate 1 and contacts the bottom of the base.

[0041] The output shaft of the hydraulic rod 16 is lifted upward, and the other end of the base is lifted, so that the base is rotated around the hinge end, so that the base can be tilted and lifted to a certain angle. The end of the hydraulic rod 16 is provided with a guide wheel 17, which is in direct contact with the base.

[0042] A connecting rod assembly 7 is provided between the support plate 1 and the base. The connecting rod assembly 7 includes two connecting rods. One end of the two connecting rods is hingedly connected, one connecting rod is hingedly connected to the support plate 1, and the other connecting rod is hingedly connected to the base.

[0043] When the base rotates, the connecting rod assembly 7 is unfolded, thereby playing a role in assisting the support of the base to ensure the stability of the base during rotation.

[0044] The driving device further comprises an auxiliary frame 14 , on which a positioning ring 15 is provided, and one end of the steel bar is placed in the positioning ring 15 .

[0045] A pulley is provided at the bottom of the auxiliary frame 14 to facilitate the movement of the auxiliary frame 14. The auxiliary frame 14 is provided to support the end of the steel bar when the steel bar is too long, so as to facilitate the connection between the steel bar and the steel bar sleeve.

[0046] The first chuck 5 and the second chuck 11 are both four-jaw chucks. The first chuck 5 can also be a three-jaw chuck; the second chuck 11 can also be a three-jaw chuck.
