Description
Technical Field
The invention relates to an elevator derrick machining device, in particular to an integrated elevator derrick machining device.
Background
With the development of elevator technology and the pursuit of manufacturers on elevator installation efficiency and installation cost, the current elevators increasingly adopt modular derrick structures, namely, all sections are preassembled in a factory building to form an integral derrick module, and all connection parts of the derrick module are punched and grooved; after the derrick module is processed, the derrick module is sent to the site for assembly; on-site installation personnel only need stack each derrick module in proper order the back through predetermined hole groove structure interconnect when the equipment, just can realize putting up elevator derrick, follow-up functional unit also can accomplish the installation through predetermined hole groove. Compared with a mode that the elevator derrick is formed by welding the sectional materials on site and the parts are installed by punching on site, the method can greatly reduce the workload of the installation site and improve the installation efficiency of the elevator.
However, the modular derrick structure has a lot of difficulties in processing, and one of the difficulties is that the specifications of the existing derrick profile and the size of a hole slot to be processed are generally large, so that the derrick profile is difficult to be punched manually, and the derrick profile needs to be processed by equipment such as a horizontal lathe or a horizontal punching machine. And because the general volume of derrick module after the equipment is great, and the position of punching is very dispersed, lead to on the one hand existing equipment to realize hardly the integral erection and the location to the derrick module, on the other hand equipment also can't once only punch to the position dispersion and towards different hole sites. Therefore, the existing treatment method for the derrick module is to process a single section, and assemble all the sections into an integrated derrick module by welding or bolt connection after the hole groove is formed. The mode can cause that each section bar is independently positioned when being processed each time, the datum planes during positioning are different, and further, the hole positions on different section bars of the derrick module deviate due to processing errors and installation errors after multiple positioning, namely, the problem that the derrick module cannot be stably connected or subsequent functional parts are inaccurately positioned is caused.
Secondly, when the existing derrick sectional material is provided with a hole groove, a certain designated plane of the sectional material is generally used as a reference for processing; however, the sectional materials inevitably have dimension errors, so that the hole and groove positions of different sectional materials cannot be completely consistent when the sectional materials are positioned and processed by taking the same plane as a reference plane, and mutual dislocation of the hole and groove at the connecting part is easily caused. Due to the defects, an installer needs to integrally assemble the elevator derrick in a factory building during assembly, manually repair the elevator derrick after the offset hole sites are checked out in the assembly process, disassemble the elevator derrick again after the elevator derrick is integrally assembled and checked to be correct, and send the elevator derrick to an installation site in batches.
Thirdly, along with the pursuit of manufacturers in the aspects of processing efficiency, structural strength, functionality and the like of the elevator shaft frame, the profile structure of the elevator shaft frame is more and more complicated at present, so that the elevator shaft frame is not processed by taking the traditional standard profiles such as channel steel, rectangular steel or I-steel as raw materials, but various complex structures are formed by casting technology, and the surface of the profile far away from one side of the position of the hole groove often appears without a plane which can be used for stable placement, so that the positioning tool of the existing equipment is difficult to position the profile, and the processing difficulty of each hole position on the profile is further increased.
Fourthly, because the section bars have straightness errors, after the elevator shaft frame is integrally built and molded, hole sites at the upper end and the lower end of the shaft frame deviate due to slight bending of the upright posts; and because the whole length of the derrick can reach tens of meters, the position deviation of tens of millimeters can be formed in comparison with the design value of the top hole position of the elevator derrick, so that the top hole position of the elevator derrick and the hole position of the top connecting piece are completely staggered, and the installation is finished by an operator in a mode of re-punching or welding.
Therefore, the existing processing equipment for the elevator derrick has the problems of difficult positioning and low processing precision.

After the derrick modules are fixed, firstly, an operator uses a certain specified hole position as a reference, the three-axis portal frame drives the machining assembly to move to the hole position, and then the drilling assembly is punched through the matching of the rotary disc 5 and each drilling module; then, the hole position is used as an initial position to process other holes and grooves in six directions on the derrick module in the same way, so that the invention can process all the holes and grooves of the derrick module under one-time positioning.
