[0071] In this embodiment, the stepping beam base C includes a base body C1, a base beam C2, and a base adjustment mechanism C3.

The adjustment bracket C31 is mounted on the base body C1, the adjustment screw C32 is mounted on the adjustment bracket C31 and is connected to the lifting support plate A14, and the adjustment nut C33 is mounted on the adjustment screw C32 and is in contact with the adjustment bracket C31.

[0073] Specifically, the working process of this electric walking beam is as follows: Figure 17 As shown, at point O1, the pipe fitting is placed on the translation beam B1 and the lifting device A2 drives the lifting beam A1 to rise upward along track 1 to point O2. At point O2, the translation beam B1 is driven by the translation device B2 to move to the right along track 2 to point O3 and the pipe fitting is placed on the support roller. At point O3, the lifting beam A1 is driven by the lifting device A2 to descend downward along track 3 to point O4. At point O4, the translation beam B1 is driven by the translation device B2 to move to the left along track 4 to point O1. This process is repeated to switch the pipe fitting between different workstations.

[0074] It should be noted that during the movement of the pipe fitting, since the movement trajectory of the lifting beam A1 is inclined upward along the lifting support plate A14, the horizontal movement distance of the lifting beam A1 can be compensated by the reverse movement of the translation beam B1 after the lifting beam A1 is raised, thus making the movement trajectory of the pipe fitting rectangular.

[0075] When the lifting mechanism A is in operation, the lifting drive sprocket A23 and the lifting driven sprocket A24 are driven by the lifting chain A25. The lifting reduction motor A22 drives the lifting drive sprocket A23 to rotate, pulling the lifting chain A25. The lifting chain A25 pulls the lifting beam A12, which in turn drives the lifting rollers A13 on the lifting beam A12 to rise along the inclined lifting support plate A14, thereby realizing the lifting action of the lifting beam A1.

[0076] The chain compensation assembly A28 can compensate the lifting height of the lifting beam A1 to avoid the breaking of the lifting chain A25 when the lifting beam A1 is lifted. When the chain compensation assembly A28 compensates the lifting height of the lifting beam A1, the compensation core rod A283 is pulled by the lifting chain A25, so that the compensation spring A284 is in a compressed state, the compensation core rod A283 is pulled out of the compensation sleeve A281, and the length of the compensation core rod A283 is pulled out to compensate the lifting height of the lifting beam A1. The tension of the lifting chain A25 can be adjusted by rotating the tensioning screw A271 in the two chain tensioning assemblies A27.

[0077] The empty load section L1 and the load bearing section L2 are arranged on the lifting support plate A14. The angle between the empty load section L1 and the horizontal plane is α1, and the angle between the load bearing section L2 and the horizontal plane is α2, where α1>α2. Since the lifting beam A1 is in an empty load state (i.e., no pipe is supported) when the empty load section L1 is in operation, and the lifting beam A1 is in a load bearing state (i.e., a pipe is supported) when the load bearing section L2 is in operation, α1>α2 is set to ensure that the lifting reduction motor A22 can shorten the lifting time under the same power.

[0078] When the translation mechanism B is working, the translation reduction motor B21 drives the translation gear B22 to rotate. Since the translation gear B22 is engaged with the translation rack B23, which is arranged at the bottom of the translation beam connecting frame B14, the translation beam main body B11 can be moved on the translation roller B13 through the translation beam connecting frame B14.

[0079] The translation adjustment assembly B25 can be used to adjust the translation reduction motor B21 to ensure the engagement accuracy of the translation gear B22 and the translation rack B23. When the translation adjustment assembly B25 is adjusted, the two adjustment nuts B256 are rotated to adjust the adjustment screw B255 to adjust the adjustment bottom plate B251. Since the translation reduction motor B21 is arranged on the adjustment bottom plate B251, the translation reduction motor B21 can be adjusted. The translation limiting mechanism B3 can prevent the translation beam B1 from colliding with the lifting beam A1 when the equipment is out of control. The translation limiting seat B31 can move within the range of the translation limiting frame B32 when the translation beam B1 is working normally.

[0080] The stepping beam base C can support the lifting mechanism A and the translation mechanism B, the position of the lifting support plate A14 is adjusted by the base adjusting mechanism C3 to improve the matching precision of the lifting roller A13 and the lifting support plate A14, the adjusting nut C33 is loosened in advance when the position of the lifting support plate A14 is adjusted, the position of the lifting support plate A14 on the base body C1 can be adjusted due to the long row of holes arranged on the base body C1, and the adjusting nut B256 is tightened after the position of the lifting support plate A14 is fixed, and the lifting support plate A14 is fixed with the base body C1.

[0081] In addition, it should be noted that the specific embodiments described in the specification, the shape of the zero, the components, the name taken, etc. can be different, and the above described in the specification is only an example of the structure of the present application.
