Description

technical field [0001] The invention relates to an elevator derrick processing device, in particular to an integrated elevator derrick processing device. Background technique [0002] With the development of elevator technology and manufacturers' pursuit of elevator installation efficiency and installation cost, more and more elevators currently adopt modular derrick structure, that is, various profiles are pre-assembled in the factory building to form an integral derrick module , and punch and slot the connecting parts of the derrick module; after the derrick module is processed, it will be sent to the site for assembly; the on-site installer only needs to stack each derrick module in sequence and pass through the preset hole slots when assembling The structures are connected to each other to realize the construction of the elevator derrick, and the subsequent functional components can also be installed through the preset hole slots. Furthermore, compared with the method o...

AI Technical Summary

Problems solved by technology

This method will cause each profile to be positioned independently every time it is processed, and the reference planes during positioning are also different, so that the hole positions on different profiles of the derrick module will be affected by processing errors and installation errors after multiple positioning. The error produces an offset, that is, the problem that the derrick module cannot be connected stably or the positioning of subsequent functional parts is inaccurate

[0004] The second is that when the current derrick profiles are opened with holes, they are generally processed based on a certain specified plane of the profile; however, due to the inevitable dimensional errors of the profiles, different profiles are positioned and aligned with the same plane as the reference plane. During processing, the positions of the holes and grooves cannot be completely consistent, which may easily cause mutual misalignment of the holes and grooves at the connection

Due to the existence of the above-mentioned defects, the installers need to assemble the elevator derrick as a whole in the factory building during assembly, and after the offset holes are found out during the assembly process, they will be manually repaired. After the overall assembly of the elevator derrick is completed and inspected After correctness, disassemble again and send to the installation site in batches

[0005] The third is that with the manufacturers' pursuit of the elevator derrick in terms of processing efficiency, structural strength and functionality, the profile structure of the elevator derrick is becoming more and more complicated, so that it no longer uses traditional channel steel, rectangular steel or I-shaped Standard profiles such as steel are processed as raw materials, but various complex structures are formed through the casting process, resulting in the fact that there is often no flat surface for stable placement on the profile surface on the side away from the hole slot, which makes the positioning tooling of existing equipment It is difficult to locate the profile, and further increases the difficulty of processing the holes on the profile

[0006] The fourth is that due to the straightness error of the profile itself, when the elevator derrick is built as a whole, the holes at the upper and lower ends of the derrick will be offset due to the slight bending of the column; and because the overall length of the derrick will reach tens of meters , so that the top hole position of the elevator derrick will have a position deviation of tens of millimeters compared with the design value, resulting in a complete misalignment with the top connecting piece hole position, which needs to be re-drilled or welded by the operator to complete the installation

[0007] Therefore, the existing processing equipment used for the elevator derrick has the problems of difficult positioning and low processing accuracy
