Description

Technical Field

[0001] This invention relates to the field of railway freight car repair and maintenance technology, specifically to a railway freight car bogie center plate and pad, and a load-bearing saddle disassembly system. Background Technology

[0002] The freight car bogie is used to support the railway freight car body to run on the track. It is an important component of railway freight cars, and bogie maintenance is of paramount importance in railway freight car maintenance.

[0003] Currently, freight car bogies are mainly maintained using a suspended bogie maintenance line. A series of disassembly, maintenance, and assembly stations are set up below the suspension line according to the process requirements for bogie-related maintenance operations. The disassembly of the bogie center plate and pads is independent of the disassembly of the bogie saddle, with separate disassembly stations for the center plate and pads and the bogie saddle below the suspension line. In this maintenance mode, manual operation is generally used for the disassembly of the center plate and pads and the bogie saddle, relying solely on manual labor with tools such as balance cranes for disassembly and transportation. This results in low automation, high labor intensity, and significant safety hazards. Because the two disassembly stations are independent—one for automatically disassembling the center plate and pads and the other for automatically disassembling the bogie saddle—it inevitably requires two rounds of transport, two independent positioning and alignment of the bogie, occupying a large maintenance space and resulting in low efficiency.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a railway freight car bogie center plate and pad, and a load-bearing saddle disassembly system to solve the problems of low automation, large space occupation, and low efficiency in existing maintenance production lines.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A bogie center plate and pad, and a load-bearing saddle disassembly system are provided. The system includes a bogie centering and positioning device, a load-bearing saddle disassembly device, a load-bearing saddle transfer robot, and a center plate and pad disassembly robot.

[0008] The load-bearing saddle disassembly device includes two longitudinal long rails, which are located on the lateral sides of the bogie centering and positioning device, respectively. The load-bearing saddle transfer robot is located on the longitudinal side of the bogie centering and positioning device, and the center plate and pad disassembly robot is located on the lateral side of the bogie centering and positioning device.

[0009] After the bogie is hoisted to the top of the bogie centering and positioning device, the center plate and pad are disassembled by the center plate and pad disassembly robot, the load-bearing saddle is disassembled by the load-bearing saddle disassembly device, and the load-bearing saddle is transferred by the load-bearing saddle transfer robot.

[0010] Furthermore, the bogie centering and positioning device includes a support base, a column, a rotating chassis, a support beam, and a guide column;

[0011] The rotating chassis is supported above the support base by the column, and the support beam is set on the top of the rotating chassis. Two guide columns are arranged horizontally on the top of the support beam. When the bogie is hoisted to the top of the bogie centering and positioning device, the guide columns are inserted into the structural holes of the bogie.

[0012] Furthermore, the bogie centering and positioning device also includes a lateral offset displacement sensor, which is located on one side of the guide column.

[0013] Furthermore, the bogie centering and positioning device also includes a rotary drive motor located on the support base, and the output shaft of the rotary drive motor is vertically arranged and equipped with a drive gear;

[0014] The rotating chassis includes a fixed ring and a driven toothed ring. The inner edge of the fixed ring has an annular groove, and the outer edge of the driven toothed ring also has an annular groove. The driven toothed ring is located inside the fixed ring, and the two annular grooves are opposite to each other and a pad ring is inserted into the groove.

[0015] The driving gear is located inside the driven gear ring, and the inner edge of the driven gear ring has internal teeth that mesh with the driving gear.

[0016] The bottom of the support beam is fixed to the top of the passive gear ring. The rotary drive motor drives the passive gear ring to rotate through the drive gear, thereby driving the support beam to rotate.

[0017] Furthermore, the bogie centering and positioning device also includes a vertically arranged positioning cylinder located at the top of the support base, and the support beam has a vertical through hole, with the positioning cylinder located inside the through hole.

[0018] Furthermore, the end of the supporting beam is provided with a longitudinal centering beam, and the top of the longitudinal centering beam is provided with a longitudinally arranged longitudinal movement limiting plate.

[0019] Furthermore, the top of the longitudinal centering beam has a longitudinal guide groove, and the bottom of the longitudinal movement limiting plate has a longitudinal guide rail, which is inserted into the longitudinal guide groove.

[0020] Furthermore, the load-bearing saddle disassembly device also includes a load-bearing saddle support frame, a lifting cylinder is provided inside the load-bearing saddle support frame, and a load-bearing saddle support platform is provided on the top of the lifting cylinder.

[0021] Furthermore, the bottom of the bearing saddle support frame is provided with a transverse short rail, which can move longitudinally on the longitudinal long rail, and the bearing saddle support frame can move laterally on the transverse short rail.

[0022] Furthermore, the operating end of the core plate and pad disassembly robot has a rotating shaft, on which a multi-point vacuum suction cup is installed, and on the other side of the multi-point vacuum suction cup is an energized electromagnet.

[0038] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "longitudinal", "lateral", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] It should also be noted that the components or parts involved in this invention are preferably selected from existing structural forms, and any components or parts that can achieve the same function can be used in the implementation of this invention.

[0042] In a specific implementation, Figure 1 The direction from top to bottom is defined as the vertical direction. Figure 1 The direction from left to right in the middle is defined as horizontal.

[0043] The existing method of disassembling railway freight car bogies has a positive effect in assembly line-style sequential maintenance scenarios. Each workstation is independent, forming an assembly line according to the operating procedures, with a clear and controllable route. With the intelligent and digital development of railway freight car maintenance, a more flexible and efficient flexible maintenance model has attracted widespread attention. The flexible maintenance model automatically adjusts the maintenance process and tooling equipment based on the actual health condition and wear level of each freight car, enabling mixed-line production of various car models and different maintenance procedures. This model requires a highly automated and integrated workstation to maximize the advantages of flexible maintenance, a requirement that the current assembly line-style sequential maintenance cannot meet.

[0044] To address this, the present invention provides a disassembly system for the center plate, pad, and bearing saddle of a railway freight car bogie. Through equipment optimization and integration, the automation integration of the maintenance station is improved, enabling the disassembly of the center plate, pad, and bearing saddle to be completed at the same station.

[0045] like Figure 1 The system includes a bogie centering and positioning device 1, a load-bearing saddle disassembly device 2, a load-bearing saddle transfer robot 3, and a center plate and pad disassembly robot 5. The bogie centering and positioning device 1 is located at the center of the site and is used to load, position, and rotate the bogie. The load-bearing saddle disassembly device 2 includes two longitudinal rails 201, located on the lateral sides of the bogie centering and positioning device 1. The load-bearing saddle transfer robot 3 is located on one longitudinal side of the bogie centering and positioning device 1, and the center plate and pad disassembly robot 5 is located on one lateral side of the bogie centering and positioning device 1. The load-bearing saddle transfer robot 3 has load-bearing saddle trays 4 on its lateral sides, and the center plate and pad disassembly robot 5 has center plate and pad trays 6 on its longitudinal sides.

[0046] All equipment is concentrated in an area centered on the bogie centering and positioning device 1, forming an integrated workstation. The overall layout structure meets the needs of bogie transfer and disassembly operations. Disassembly of the two key components, the center plate and pad, and the load-bearing saddle, can be completed at this workstation without the need for transfer, making it suitable for mixed-line maintenance of multiple bogie models. After the bogie is hoisted to the top of the bogie centering and positioning device 1, the center plate and pad disassembly robot 5 disassembles the center plate and pad, the load-bearing saddle disassembly device 2 disassembles the load-bearing saddle, and the load-bearing saddle transfer robot 3 transfers the load-bearing saddle. Both the center plate and pad disassembly robot 5 and the load-bearing saddle transfer robot 3 are six-axis industrial robots, with the operating end selected according to their respective operational tasks.

[0047] like Figure 2-4 The bogie centering and positioning device 1 is a core auxiliary mechanism for the robot's disassembly center plate, pad, and load-bearing saddle. It includes a support base 110, a column 111, a rotating chassis 102, a support beam 104, a guide column 105, a lateral offset displacement sensor 106, a rotary drive motor 109, and a positioning cylinder 103.

[0048] The support base 110 is a flat plate structure, which is fixed to the ground by bolts. The support base 110 is equipped with a base sleeve 101 on the top periphery to protect other equipment installed on the top of the support base 110.

[0049] The rotating chassis 102 is supported above the support base 110 by a column 111. The rotating chassis 102 includes a fixed ring 114 and a driven gear ring 113. The inner edge of the fixed ring 114 has an annular groove, and the outer edge of the driven gear ring 113 also has an annular groove. The driven gear ring 113 is located inside the fixed ring 114, and the two annular grooves are opposite each other with a washer ring inserted in the groove. The fixed ring 114 is fixed relative to the column 111, and the driven gear ring 113 can rotate within the fixed ring 114.

[0050] A rotary drive motor 109 is located on a support base 110. The output shaft of the rotary drive motor 109 is vertically arranged and equipped with a drive gear 112, which is located inside a driven gear ring 113. The inner edge of the driven gear ring 113 has internal teeth that mesh with the drive gear 112. The rotary drive motor 109 can drive the driven gear ring 113 to rotate through the drive gear 112.

[0051] The support beam 104 is mounted on top of the rotating chassis 102. Specifically, the bottom of the support beam 104 is fixed to the top of the driven gear ring 113 of the rotating chassis 102. When the rotary drive motor 109 drives the driven gear ring 113 to rotate via the drive gear 112, it can drive the support beam 104 to rotate. This operation can complete the rotation of the bogie, allowing different positions of the bogie to face the robot for corresponding disassembly operations.

[0052] Two guide columns 105 arranged laterally on the top of the supporting crossbeam 104 are provided. When the bogie is hoisted to the top of the bogie centering and positioning device 1, the guide columns 105 are inserted into the structural holes of the bogie to achieve positioning of the bogie. The guide columns 105 can adopt a lifting structure, and before the bogie is lowered onto the supporting crossbeam 104, the guide columns 105 rise upward from inside the supporting crossbeam 104. In addition, changing the position of the guide columns 105 can be used for the front and rear centering of different bogie models.

[0053] The lateral offset displacement sensor 106 is located on one side of the guide column 105 and can measure the lateral left and right offset of the bogie. The offset data can be used for robot motion planning and correction. The lateral offset displacement sensor 106 measures and determines the left and right offset of the bogie, and then feeds the offset data back to the load-bearing saddle disassembly device 2 and the center plate and pad disassembly robot 5, synchronously calling the corresponding positioning parameters. No manual adjustment is required, which meets the needs of multi-model mixed line maintenance.

[0054] The positioning cylinder 103 is vertically positioned at the top of the support base 110 and can be fixed to the inner wall of the base sleeve 101 by a bracket. The support beam 104 has a vertical through hole, and the positioning cylinder 103 is located in the through hole. When the bogie is transported, its direction may be at a 90-degree position, requiring the bogie centering positioning device 1 to rotate and position it to facilitate the disassembly of the load-bearing saddle. To prevent rotational errors from causing misalignment of the four load-bearing saddles, the positioning cylinder 103 can be used for rotational positioning.

[0055] The end of the supporting crossbeam 104 is provided with a longitudinal centering beam 107, and the supporting crossbeam 104 and the two longitudinal centering beams 107 form an I-shaped composite beam. The top of the longitudinal centering beams 107 is provided with longitudinally arranged longitudinal movement limiting plates 108, each with a ramp on its inner side. When the bogie descends, it is guided by the ramps to continue falling and contact the supporting crossbeam 104, thus achieving front-to-back centering. In addition, the top of the longitudinal centering beams 107 has a longitudinal guide groove, and the bottom of the longitudinal movement limiting plates 108 has a longitudinal guide rail. The longitudinal guide rail is inserted into the longitudinal guide groove, allowing the position of the longitudinal movement limiting plates 108 to be adjusted forward and backward.

[0056] like Figure 6The bogie disassembly device 2 also includes a bogie support frame 205, which contains a lifting cylinder 204. A bogie support platform 203 is located on top of the lifting cylinder 204. When the bogie lands on the support beam 104, the bogie rests on the bogie support platform 203, and the lifting cylinder 204 rises, lifting the bogie upwards to complete the disassembly. A transverse short rail 202 is located at the bottom of the bogie support frame 205. The transverse short rail 202 can move longitudinally on the longitudinal long rail 201, and the bogie support frame 205 can move laterally on the transverse short rail 202. After the bogie is disassembled, the bogie support frame 205 moves bidirectionally under the support of the transverse short rail 202 and the longitudinal long rail 201, converging near the bogie transfer robot 3. The robot then picks up the bogie from the transfer fork 301 at its operating end and transfers it to the bogie tray 4.

[0057] like Figure 5 The operating end of the core plate and pad disassembly robot 5 has a rotating shaft, on which a multi-point vacuum suction cup 501 is mounted. An energized electromagnet 502 is installed on the other side of the multi-point vacuum suction cup 501. After the bogie lands on the support beam 104, one side faces the core plate and pad disassembly robot 5. The core plate and pad disassembly robot 5 disassembles the pad using the multi-point vacuum suction cup 501 and the core plate using the energized electromagnet 502. Afterward, the bogie is rotated to the other side, and the core plate and pad disassembly robot 5 performs the disassembly operation on the other side.

[0058] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
