[0002] Traction converters are auxiliary traction converters used in high-speed trains and urban rail transit such as subways. With the surge in demand for rail transit, the demand for traction converters is also constantly increasing. Assembling traction converters requires many tools for support and handling. The traction converters used in the entire train weigh up to 3 tons and are approximately 3 to 4 meters long and wide. During the production and assembly process, they need to be moved from one workstation to another. Due to their large size and weight, this movement presents significant difficulties and affects production progress.

DETAILED DESCRIPTION

[0044] ​​In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0045] With the rapid development of urbanization construction, the demand for high-speed motor trains and subways in urban rail transit is also increasing. The traction converter is one of the key components used in high-speed motor trains and urban rail transit. Its main function is to convert the electric energy between direct current and alternating current, and to convert the electric energy from the catenary into uniform, undulating and uninterrupted electric energy required by the traction motor. Due to the large volume and heavy weight of the traction converter, it is very inconvenient to transport it from one station to another during production assembly. The operation of one-time handling takes a long time and has low efficiency, which is difficult to meet the demand of large-scale production.

[0046] At present, in the production and assembly of the traction converter, a motorized handling vehicle is used to realize the handling. The motorized handling vehicle moves below the production line and relies on the hydraulic device inside the motorized handling vehicle to lift the traction converter. During handling, the operator needs to continuously adjust the position of the motorized handling vehicle to align it with the handling equipment, and continuously control the motorized handling vehicle to make upward, downward, forward and backward movements, so as to transfer the traction converter from one station to another. The operation process of one-time handling needs a long time, and multiple traction converters need to be handled on the whole line, which requires multiple people to operate cooperatively, resulting in long time consumption, low efficiency and high equipment cost. In addition, in the current production and assembly of the traction converter, a matching motorized handling vehicle needs to be configured, which consumes high cost.

[0047] In view of the above background, the present application will be described below with reference to the accompanying drawings. Figures 1-18 The traction converter assembly line uninterrupted transfer device provided by the embodiment of the present application is described.

[0048] Referring to FIGS. 1 and 2, Figure 1 and Figure 2 The traction converter assembly line uninterrupted transfer device provided by the embodiment of the present application is described. The traction converter assembly line uninterrupted transfer device comprises a track transportation line 10, a walking mechanism 30 and a lifting mechanism 50. The track transportation line 10 has a two-layer structure, and the walking mechanism 30 walks horizontally on the upper layer structure of the track transportation line 10.

[0049] Referring to FIGS. 1 and 2, Figure 3 and Figure 4As shown, the lifting mechanism 50 is arranged on the walking mechanism 30, and the goods 40 lifted by the lifting mechanism 50 are transported longitudinally between the upper structure of the track transportation line 10 and the lower structure of the track transportation line 10, so as to realize the lifting movement of the goods 40, Figure 2 As shown, the lifting mechanism 50 is arranged on the walking mechanism 30, and the goods 40 lifted by the lifting mechanism 50 are transported longitudinally between the upper structure of the track transportation line 10 and the lower structure of the track transportation line 10, so as to realize the lifting movement of the goods 40,

[0050] The goods 40 mentioned in the present application include traction converter assemblies that are not yet assembled and traction converter assemblies that have been assembled.

[0051] Reference Figure 2 and Figure 4 As shown, the goods 40 lifted by the lifting mechanism 50 are transported transversely and suspended by the walking mechanism 30, so as to realize the transportation of the goods 40 between different stations of the track transportation line 10. The suspended transportation of the goods 40 lifted by the lifting mechanism 50, i.e., the hoisted goods 40 can cross any empty and loaded station, so that the hoisted goods 40 can be suspended and placed on any empty station of the support line.

[0052] The lifting mechanism 50 lifts the goods 40 to a preset height position, and the walking mechanism 30 moves transversely to drive the lifted goods 40 to be transported transversely and transported above any available station of the track transportation line 10. Through the lifting movement of the lifting mechanism 50, the goods 40 are placed on the station, so as to realize the transfer of the goods 40 from one station to another station. Even if the station below the goods 40 carrying path is occupied, the goods 40 can be carried to the next station by crossing the occupied station, and multiple goods 40 can be carried and transported at the same time. Therefore, the operation of multiple people is no longer needed, the use is more convenient, the carrying efficiency is improved, the carrying time is saved, and the demand of large-scale production is met.

[0053] Reference Figure 4 and Figure 13 As shown, the track transportation line 10 includes a plurality of pairs of support seats 13 arranged in sequence, a pair of tracks 12 arranged at the upper ends of the plurality of pairs of support seats 13, and a pair of load-bearing beams 11 arranged at the middle portions of the plurality of pairs of support seats 13. The walking mechanism 30 moves transversely along the pair of tracks 12, and the load-bearing beams 11 are used to support the goods 40 placed on different stations of the track transportation line 10.

[0054] Reference Figure 4 and Figure 13 As shown, each pair of support seats 13 is arranged oppositely, and the support seat 13 includes a goods carrying column 131, a lifting device carrying column 132, and at least one connecting beam 133. The goods carrying column 131 and the lifting device carrying column 132 are arranged parallel to each other, and the connecting beam 133 is connected vertically between the goods carrying column 131 and the lifting device carrying column 132, so as to enhance the stability of the overall structure of the support seat 13.

[0055] Specifically, the connecting beams 133 are two, and the two connecting beams 133 are arranged in an upper and lower interval.

[0056] Referring to Figure 12 and Figure 13 As shown in the drawings, the load-bearing beam 11 is arranged at the top of the cargo carrying column 131, and a plurality of cargo carrying columns 131 are commonly supported at the lower end of the load-bearing beam 11, and the load-bearing beam 11 has a load-bearing beam interface 111 on the inner side of the load-bearing beam 11, and the load-bearing beam 11 is a multi-section structure connected to each other to form.

[0057] The rail carrying beam 14 is arranged at the upper end of the lifting device carrying column 132, and a plurality of lifting device carrying columns 132 are commonly supported at the lower end of the rail carrying beam 14, and the rail 12 is arranged on the rail carrying beam 14, and the rail carrying beam 14 has a rail carrying beam interface 141 on the inner side of the rail carrying beam 14, and the rail carrying beam 14 is a multi-section structure connected to each other to form.

[0058] It is easy to understand that the height of the lifting device carrying column 132 is greater than the height of the cargo carrying column 131, so that the load-bearing beam 11 arranged at the upper end of the cargo carrying column 131 serves as the lower structure of the rail transport line 10; the rail carrying beam 14 arranged at the upper end of the lifting device carrying column 132 and the rail 12 arranged on the rail carrying beam 14 serve as the upper structure of the rail transport line 10, and the double-layer structure of the rail transport line 10 improves the safety, speed and accuracy of the assembly production line, breaks through the limitations of the traditional production line structure, and improves the production progress.

[0059] In order to strengthen the strength of the rail carrying beam 14, a plurality of rib plates 142 are arranged in an interval on both sides of the rail carrying beam 14.

[0060] In order to increase the stability of the support seat 13, a plurality of rib plates 134 are arranged at the lower end of the cargo carrying column 131 and the lifting device carrying column 132, and the plurality of rib plates 134 are evenly distributed around the circumference of the cargo carrying column 131 and the lifting device carrying column 132, and in addition, chemical bolts are used to fix the lower end of the cargo carrying column 131 and the lifting device carrying column 132 to the factory floor.

The rollers 33 under the two roller seats 32 on one side of the main beam frame 31 are located on the same straight line, so as to ensure that the walking mechanism 30 can move forward and backward smoothly.

[0063] The side surface of the roller seat 32 is provided with at least one walking motor 35 for driving the roller 33 to roll. The walking motor 35 drives the roller 33 to roll synchronously through a frequency converter.

The lead screw nut mechanism 56 includes a threaded sleeve seat 562 fixedly connected with the walking mechanism 30, and a lead screw 561 sleeved in the threaded sleeve seat 562. The lower end of the lead screw 561 is connected with the lifting beam 57.

[0065] The lifting driving motor 51 drives the lead screw nut mechanism 56 to act, so as to realize the lifting beam 57 lifting movement driven by the lead screw 561.

The transmission mechanism includes a first speed conversion device 52, a first transmission shaft 53, a second speed conversion device 54, and a second transmission shaft 55. The output shaft of the lifting driving motor 51 is connected with the first speed conversion device 52. The left and right sides of the first speed conversion device 52 are respectively connected with one end of the two first transmission shafts 53. The other end of the two first transmission shafts 53 is respectively connected with the two second speed conversion devices 54. The left and right sides of the second speed conversion device 54 are respectively connected with one end of the two second transmission shafts 55. The other end of the second transmission shaft 55 is connected with the threaded sleeve seat 562.

[0068] In the present application, the four lead screw nut mechanisms 56 are driven by one lifting driving motor 51. The speed conversion devices in the transmission mechanism ensure that the four lead screw nut mechanisms 56 act synchronously, so that the four lead screws 561 synchronously lift or synchronously descend, and ensure that the lifting mechanism 50 drives the lifting frame 20 to lift or descend smoothly.

[0069] The first speed conversion device 52 and the second speed conversion device 54 are both the integral structure combined by a speed changer and a converter.

[0070] When the lifting mechanism 50 works, the lifting driving motor 51 drives the output shaft of the lifting driving motor 51 to rotate, and then drives the two first transmission shafts 53 to rotate through the speed conversion and output reversing of the first speed conversion device 52, and then drives the four second transmission shafts 55 to rotate through the speed conversion and output reversing of the second speed conversion device 54, and then drives the screw nut mechanism 56 to act through the second transmission shaft 55, and the threaded sleeve seat 562 drives the screw rod 561 to move up and down.

Specifically, two limit switches 58 are arranged on the lead screw 561, and the two limit switches 58 are spaced apart in the height direction, so as to respectively detect the upper limit position and the lower limit position of the movement of the lead screw 561.

[0081] Reference Figure 1 And Figure 2 As shown in the figure, the track transportation line 10 is not limited to be connected by welding, and electrical limit devices and mechanical limit devices are arranged at both ends of the track 12 of the track transportation line 10, which are used to prevent the walking mechanism 30 from falling off the track.

[0082] In order to more conveniently carry and pull the traction converter in the production and assembly process, the traction converter assembly line uninterrupted transfer device provided in the present application can also be provided with a flashlight door manipulator and a remote control manipulator.

[0083] In operation, the lifting mechanism 50 lifts the lifting frame 20 loaded with the goods 40, and after the walking mechanism 30 walks, the goods 40 is transferred from above one station to above another available empty station, the lifting mechanism 50 lowers, and the lifting frame 20 loaded with the goods 40 is placed on the other available empty station, so as to realize the transportation of the goods 40.
