[0002] In the construction industry, sleeve mechanical connection has been widely used. In the process of steel sleeve connection, the steel wire head and the sleeve are generally tightened using a pipe wrench or a steel wrench. First, fix one steel bar, screw on the sleeve, and then screw the other relative steel bar into the sleeve until the two steel bars are connected.

[0019] The sleeve control component includes a driving wheel 103 and a driven wheel 104. The driving wheel 103 is arranged in the sliding frame 102 through a rotating shaft. The driving wheel 103 is fixedly connected to the rotating shaft. The driven wheel 104 is rotatably arranged in the arc section of the fixed frame 101.

[0024] Furthermore, the sliding frame 102 also includes a second upper panel and a second lower panel arranged in parallel, and the second upper panel and the second lower panel are respectively connected vertically to the side panel; the driving wheel 103 is arranged between the second upper panel and the second lower panel of the sliding frame 102 through a rotating shaft; the center of the driving wheel is located at the perpendicular bisector of the center line of the two driven wheels 104. The driving wheel surface selected in this device is a vertical fine gear, the gear hardness is large, and the tooth width also has certain requirements, which can reduce the damage of the gear, and the driving wheel and the driven wheel of different gears can be replaced for different sleeves. If the outer surface of the sleeve is gear-shaped, the sleeve gear is engaged with the driving wheel and the driven wheel, and it will be more convenient to connect the sleeve. The driving wheel is connected to the power input device through a rotating shaft, and the energy input by the power input device is transmitted to the driving wheel through the rotating shaft.

[0025] Furthermore, the control rod 105 is a screw, and a nut 108 is arranged between the first upper panel and the first lower panel of the vertical section of the fixed frame 101. The screw is arranged in the nut 108. The axis of the screw passes through the center of the driving wheel 103 and coincides with the perpendicular bisector of the center line connecting the two driven wheels 104. The screw arranged in the nut is adjusted by external force. The screw is also connected to the U-shaped connecting piece, and the sliding frame 102 is pushed to a suitable position with the sleeve as a whole, thereby starting the process of automatic connection of the sleeve.

For example, one end of the input shaft is connected to a universal pneumatic cannon joint, and the universal pneumatic cannon joint is connected to a pneumatic cannon, and the pneumatic cannon becomes the power source of the entire device.

[0028] Further, such as Figure 4The gear set shown is a bevel gear set, including an active bevel gear 110 and a driven bevel gear 111, wherein the active bevel gear 110 is arranged at the end of the input shaft 107, and the driven bevel gear 111 is arranged on the outer surface of the second upper panel, and the driven bevel gear 111 is fixedly connected to the end of the rotating shaft outside the outer surface of the second upper panel. The energy generated by the pneumatic blaster is transmitted to the active bevel gear through the input shaft, and the active bevel gear is a bevel gear perpendicular to the input shaft. The active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear is a bevel gear parallel to the input shaft.

[0031] The application of the sleeve automatic connection device of the present invention solves the problem that people cannot simultaneously ensure the connection quality and connection efficiency during the sleeve connection process. Corresponding to the above-mentioned sleeve automatic connection device, its implementation method is as follows:

[0032] During the connection process of the steel bar sleeve, the steel bar connecting thread heads are centered on the same axis, and the steel bar sleeve connection automatic device is used. First, the sleeve is placed between the driving wheel and the driven wheel through the control lever, and the position of the control lever is adjusted to allow the driving wheel and the driven wheel to clamp the straight thread sleeve. According to the torque requirements in the straight thread sleeve connection specification and the direction in which the sleeve needs to rotate, the torque and rotation direction of the pneumatic pneumatic gun are adjusted, and the pneumatic pneumatic gun is turned on.

The second step: after the thread head is processed, the protective cover is put on, and the connection is waiting for the steel cage to be processed. If it does not need to be hoisted in sections, the steel bar can be directly connected by the connection device of the steel sleeve. If it needs to be hoisted in sections, the relevant main bars are first connected as required, and then the steel cage is processed on the processing platform. After the processing is completed, the steel cage is disassembled and hoisted in sections. Step 3: After the first section of the steel cage is lowered into a specific position, use a level ruler to coordinate the crane to adjust the level of the steel cage. After it is level, use a rod-piercing device to fix the first section of the steel cage, then lift the second section of the steel cage and move it above the first section. Adjust the position of the second section of the steel cage to align the vertical connecting steel bars. After manually aligning a single connecting sleeve and steel bar, start the steel sleeve connection automation device to quickly connect the steel bar and sleeve.
