The electric gripper is a device widely used in fields such as robots and automated production lines. It uses an electric drive system to control the opening and closing of the gripper, thereby realizing the clamping, handling, or operation of objects. It belongs to very mature existing technologies. Therefore, the present invention does not introduce its working principle and specific structure in detail.

A stepping motor is a kind of motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input of a pulse signal, the rotor rotates an angle or moves forward one step. It is widely used in real life, and its working principle will not be introduced in detail here. A strip-shaped opening matching the threaded rod 302 is opened on the construction roof 101.

A pressure-sharing groove matching the pressure-sharing wheel 305 is opened on the upper side wall of the construction roof slab 101, and both ends of the pressure-sharing groove are chamfered. Through the combined use of the pressure-sharing wheel 305 and the pressure-sharing plate 304, the downward pulling force of the threaded sleeve 303 on the threaded rod 302 can be shared, avoiding the deformation and eccentricity of the threaded rod 302 during long-term use.

The electric sliding sleeve 206 moves on the electric ring rail 205. The hollow roller 211 drives the dust removal brush 212 to wipe the outer surface of the interface of the first pipeline 103 and the inner surface of the socket of the second pipeline 104 respectively. After the electric sliding sleeve 206 rotates one circle, the elastic touch switch 214 is squeezed once. The flipping motor 210 drives the hollow roller 211 to rotate 180 degrees. The oiling brush 213 oils the outer surface of the interface of the first pipeline 103 and the inner surface of the socket of the second pipeline 104. After the electric sliding sleeve 206 continues to rotate two circles and the elastic touch switch 214 is squeezed for the third time, it will turn off the electric sliding sleeve 206, control the first stepping motor 202 to rotate, and the rack 201 drives the annular sleeve 204 to rise and reset.

[0051] S3: After the rack 201 rises to the top, the elastic extrusion switch 307 on it controls the second stepping motor 301 to rotate forward. The first electric jaw 105 controls the first pipeline 103 to be inserted into the socket of the second pipeline 104 to complete the construction docking of the municipal engineering pipeline.

[0052] During the use process, the first electric gripper 105 and the second electric gripper 106 respectively clamp the corresponding first pipeline 103 and the second pipeline 104 to align them. The tooth column 203 drives the annular sleeve 204 to descend to a horizontal height concentric with the first pipeline 103 and the second pipeline 104.

The hollow roller 211 drives the dust removal brush 212 to wipe the outer surface of the interface of the first pipeline 103 and the inner surface of the socket of the second pipeline 104 respectively. After the electric sliding sleeve 206 rotates one circle, the elastic touch switch 214 is squeezed once. The flipping motor 210 drives the hollow roller 211 to rotate 180 degrees, and the oiling brush 213 oils the outer surface of the interface of the first pipeline 103 and the inner surface of the socket of the second pipeline 104. After the electric sliding sleeve 206 continues to rotate two circles and the elastic touch switch 214 is squeezed for the third time, it will control the electric sliding sleeve 206 to stop moving, and at the same time control the first stepping motor 202 to rotate. The rack 201 drives the annular sleeve 204 to rise and reset;

[0053] When the rack 201 rises to the top, the elastic extrusion switch 307 on it controls the output shaft of the second stepping motor 301 to drive the threaded rod 302 to rotate forward. The threaded sleeve 303 threadedly connected to it drives the first pipeline 103 to be inserted into the socket of the second pipeline 104 through the first electric gripper 105, completing the construction docking of the municipal engineering pipeline. The automation degree is high, and the dust removal, oiling and subsequent docking processes do not require the assistance of staff, which can effectively ensure the uniformity of oiling and improve the sealing performance of the subsequent pipeline docking.
