Description

Technical Field

[0001] The present invention relates to the field of rail transportation, and in particular to a supporting device for component disassembly and assembly and a method for disassembling and assembling a traction drive device. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The traction drive device 2 in the bogie structure of some low-floor rail vehicles is different from the traction drive device commonly used in the prior art. Figure 1 and Figure 2 As shown, the traction drive device includes a traction motor 3, a gearbox 4, and a coupling. The traction motor 3 drives both wheels simultaneously. Each bogie 1 is equipped with two independent traction motors, one each driving the front and rear wheel pairs 7 on the same side. The traction motor 3 and gearbox 4 are connected by a coupling to transmit torque.

[0004] During installation, the traction drive devices need to be installed on both sides of the bogie 1. However, the internal gears of the two traction drive devices are arranged differently and cannot be misaligned during assembly. Figure 3 As shown, the installation positions of the traction drive devices on both sides on the bogie are positioned by the transverse shock absorber seat 6; after fixing the bogie axle bridge, the traction drive device 2 is required to move slowly close to the wheelset; Figure 4 As shown, because the mass of each set of traction drive devices 2 reaches 1.2 tons, in order to prevent the bogie from overturning during installation, the traction drive devices 2 on both sides need to be installed on the bogie 1 at the same time; In order to meet the above-mentioned assembly requirements, the prior art usually uses an overhead crane to lift the traction drive devices on both sides for installation. However, there are certain safety issues in the overhead crane lifting, and the traction drive devices on both sides are lifted separately by two sets of overhead cranes, which makes the on-site environment setting more complicated. In addition, two independent overhead cranes require two operators to cooperate to ensure the simultaneous installation of the two traction drive devices, which has certain installation difficulties. In addition, other operators are required to follow the movement of the traction drive device 2, which occupies a large number of operators as a whole, resulting in low installation efficiency.

[0005] There are some bogie unloading equipment or bogie lifting platforms in the prior art, the purpose of which is to disassemble or repair the bogie 1 from the vehicle through the platform. The overall structure is adapted to the bogie structure and cannot achieve the simultaneous movement of two traction drive devices toward the bogie; and even if the existing platform is used for the installation of the traction drive device 2, the positioning accuracy requirement of the traction drive device 2 is relatively high, and how to accurately position and install it is also a problem that needs to be considered. Now it mainly relies on manual positioning, and manual positioning is performed by holding multiple tools, and the installation efficiency is low.

[0006] And not only the installation of traction drive device 2 exists above-mentioned problem, other need to install the component also exists above-mentioned problem simultaneously. SUMMARY

[0008] In order to achieve the above-mentioned purpose, the present application is realized by the following technical scheme: In a first aspect, the present application discloses a support device for component disassembly, comprising two side support assemblies, which can be moved and can be moved to the two sides of the longitudinal direction of the component to be installed, the support assembly comprises an upper platform, which can support the component, the upper platform can be lifted, and the upper platform can be moved in the transverse and longitudinal directions of the component to be installed to push the component into the component to be installed, the upper platform is provided with a positioning component to position the component to be supported, and the positioning component of one side support assembly is provided with two light emitters, one of which emits a light beam towards the positioning position of the component to be installed, and the other emits a light beam towards the positioning component of the other side support assembly.

[0012] In the supporting device for component assembly and disassembly as described above, the positioning components of the two supporting assemblies are arranged opposite to each other, or the positioning components of the supporting assemblies on both sides are placed on the same side in the transverse direction of the component to be installed.

[0013] As described above, a support device for component assembly and disassembly, the upper platform includes a first platform, the first platform is connected to the second platform, the second platform can move along the longitudinal direction of the part to be installed relative to the first platform, the second platform is connected to the third platform, the third platform can move along the transverse direction of the part to be installed relative to the second platform, and the third platform is used to support the component.

[0014] As described above, a supporting device for component disassembly and assembly is provided with protective pads on the surface of the upper platform. The protective pads are provided on both sides and the middle of the upper platform in the width direction. The protective pads are provided to protect the components and avoid collision problems of the components.

[0017] In the supporting device for assembly and disassembly of components as described above, the supporting leg locking component includes a supporting rod, which can be locked after passing through the bottom platform, and the diameter of the bottom end of the supporting rod is increased.

[0018] In a second aspect, the present invention further discloses a method for disassembling and assembling a traction drive device, which uses the support device for component disassembly and assembly, and includes the following contents: The support assembly supports the traction drive device through the upper platform and positions the traction drive device through the positioning component; Each support assembly drives the traction drive device to move to both sides of the bogie in the longitudinal direction; One of the light emitters emits a light beam toward the positioning position of the bogie to calibrate the installation position of the traction drive device on one side.

After the adjustment is completed, the traction drive devices on both sides are positioned, and the traction drive devices are driven by the support components on both sides to move toward the bogie at the same time to complete the installation of the traction drive devices.

[0019] The beneficial effects of the present invention are as follows: 1) In the present invention, for components to be installed on both sides of the part to be installed at the same time, support assemblies on both sides are provided. The support assemblies support the components through the upper platform. The upper platform can move along the longitudinal direction of the part to be installed to determine the position of the components. The movement along the longitudinal direction of the part to be installed facilitates the simultaneous installation of components on both sides at the part to be installed. The upper platform is provided with a positioning component, which positions the position of the component on the upper platform. Then, a light emitter that emits a light beam toward the positioning position of the part to be installed is used to accurately position the component on one side, and then another light emitter is used to accurately position the component on the other side, thereby ensuring accurate installation of components on both sides.

[0020] 2) The present invention is provided with a controller, which controls the movement of the support assembly and the movement of each light emitter. If the light receiver does not receive a signal and does not feed back to the controller, it means that the position of the component is not accurately positioned, and the controller is required to control the movement of the support assembly. After the light receiver receives the signal and feeds back to the controller, the controller controls the support assembly to stop moving, indicating that the position of one side of the component has been aligned and positioning is completed. In this way, there is no need for operators to perform positioning, and the positioning efficiency is high.

[0021] 3) The positioning component in the present invention is L-shaped, which not only can position the component in the X and Y directions, but also facilitates the installation of two light emitters, ensuring that one of the light emitters emits a light beam toward the positioning position of the component to be installed by being lower than the set position of the component, and ensuring that the other light emitter can emit a light beam toward the positioning component at the other side support assembly.

[0022] 4) The entire support assembly structure of the present invention is reasonably arranged, and the support assembly can be raised and lowered. The upper platform realizes the movement of the components along the longitudinal and transverse directions of the parts to be installed through the cooperation of multiple platforms. The movement of the components along the longitudinal direction of the parts to be installed ensures the positioning of the components, and the movement of the components along the transverse direction of the parts to be installed ensures the movement of the components toward the parts to be installed so as to install the components; and the bottom platform is also provided with a support leg locking component, which can contact the ground, thereby ensuring the stability of the components, especially the components with larger mass, when supporting, and avoiding overturning of the support device.

[0023] 5) The method for disassembling and assembling the traction drive unit of the present invention first supports the traction drive unit by a support assembly and preliminarily positions the components by a positioning component.

Then, another light emitter is used to accurately position the traction drive unit on the other side. After accurate positioning, the support assemblies on both sides are moved simultaneously to achieve simultaneous installation of the traction drive units on both sides.

DETAILED DESCRIPTION

[0038] It should be noted that the following detailed description is illustrative only, and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0039] It should be noted that the terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should be understood that when the terms "comprise" and / or "include" are used in this specification, there is a presence of the features, steps, operations, devices, components and / or their combinations; As introduced in the background, the two-sided traction drive device or other components in the prior art have the problem of low installation efficiency due to the simultaneous and accurate positioning installation. In order to solve the above technical problems, the present application provides a support device for disassembling and assembling a component.

[0040] Embodiment one In a typical embodiment of the present application, with reference to Figure 5 and Figure 6As shown, a support device for component assembly and disassembly includes two side support assemblies, both of which are movable and can be moved to both sides of the longitudinal direction of the part to be installed, respectively. The support assembly includes an upper platform, which can support the component. The upper platform can be raised and lowered, and the upper platform can be moved along the transverse and longitudinal directions of the part to be installed to push the component into the part to be installed. The upper platform is provided with a positioning component 22 to position the component to be supported, wherein the positioning component 22 of the support assembly on one side is provided with two light emitters, one of which emits a light beam toward the positioning position of the part to be installed, and the other light emitter emits a light beam toward the positioning component of the support assembly on the other side.

[0041] It needs to be explained that the upper platform is provided with a positioning component 22, which positions the position of the component on the upper platform, and then accurately positions the component on one side through a light emitter that emits a light beam toward the positioning position of the part to be installed, and then accurately positions the component on the other side through another light emitter, and then the supporting components on both sides can simultaneously drive the components on both sides to move, thereby ensuring the accurate installation of the components on both sides.

[0042] In this embodiment, the support assembly includes a bottom platform 9, which is a frame-type structural member. Considering that the bottom platform needs to remain stable, the bottom platform 9 can be provided with two layers of frames, which are connected. Wheels 15 are respectively provided at the four corners of the lower side of the bottom platform 9. The wheels 15 are lockable wheels for locking. The bottom platform 9 is connected to the upper platform through a lifting component 12. Figure 8 and Figure 9 As shown, the lifting components 12 can be four hydraulic cylinders, which are evenly distributed. The hydraulic cylinders pass through the bottom platform 9 and are connected to the upper platform. The four hydraulic cylinders are connected to the main cylinder 21 supported by the bottom platform 9. The bottom of the main cylinder 21 is supported by the bottom plate 5, and a guide rod 10 is respectively provided on the inner side of each hydraulic cylinder. One end of the guide rod 10 is fixed to the bottom of the upper platform, and the guide rod 10 is provided through the bottom platform 9.

[0043] In order to facilitate pushing the entire support assembly, a handrail 17 is provided on one side of the bottom platform 9 .

[0044] Considering that some components such as the traction drive device have a large mass, a support leg locking component 14 is provided on the side of the bottom platform 9. The height of the support leg locking component 14 relative to the bottom platform 9 is adjustable, and the bottom of the support leg locking component can be in close contact with the ground to improve the stability of the support assembly; in some examples, reference Figure 7 As shown, the support leg locking component 14 is rotatable relative to the bottom platform 9. When supporting the component, the support leg locking component 14 is swung to both sides of the bottom platform to stably support the entire device. After use, the support leg locking component is retracted.

[0045] Specifically, the support leg locking component 14 includes a support rod 18, which is arranged on both sides of the bottom platform 9 in the width direction, with two support rods 18 on each side. The support rod 18 is a threaded rod, which passes through both sides of the bottom platform and can be locked through a threaded structure. A handwheel 20 is provided at the top of the threaded rod to facilitate the rotation of the threaded rod, and a limit section 19 is provided at the bottom end of the threaded rod. The limit section 19 is a cylindrical end to prevent the threaded rod from detaching from the bottom platform 9.

[0046] In this embodiment, the upper platform includes a first platform 13, the first platform 13 is connected to the lifting component 12, the first platform 13 is connected to the second platform 11, the second platform 11 can move along the longitudinal direction of the part to be installed relative to the first platform 13, the second platform 11 is connected to the third platform 8, the third platform 8 can move along the transverse direction of the part to be installed relative to the second platform 11, and the third platform 8 is used to support the component.

[0047] To avoid interference between the second platform 11 and the first platform 13 and the supporting leg locking components on both sides when the supporting assembly is retracted, the lengths of the first platform 13 and the second platform 11 are smaller than the length of the third platform 8 .

[0048] Specifically, an X-direction moving component is arranged between the first platform 13 and the second platform 11. The X-direction moving component can be an X-direction linear slide rail. The slider of the X-direction linear slide rail is connected to the second platform 11 to drive the second platform 11 to move along the longitudinal direction of the part to be installed, so as to facilitate the alignment of the component with the positioning position of the part to be installed. A Y-direction moving component is arranged between the second platform 11 and the third platform 8 to push the third platform 8 to move in the Y direction. The Y-direction moving component is a Y-direction linear slide rail. The slider of the Y-direction linear slide rail is connected to the third platform 8, so that the third platform 8 drives the corresponding component to move in the lateral direction of the part to be installed to install the component.

[0049] It should be noted that, in this embodiment, the component may be the traction drive device 2 , the part to be installed may be the bogie, and the positioning position of the part to be installed may be the lateral shock absorber seat 6 of the bogie.

[0050] A protective pad 16 is provided on the surface of the third platform in the upper platform. The protective pad 16 is provided on both sides and the middle of the width direction of the upper platform, that is, the protective pad 16 is provided at the contact position between the traction drive device 2 and the third platform 8. The protective pad 16 can be a rubber pad. The protective pad covers the width direction of the third platform 8. The interval between two adjacent protective pads is set. The setting of the protective pad 16 is used to protect the components and avoid the problem of component collision. In addition, the protective pad 16 ensures that the horizontal center line of the traction motor 3 and the gear box 4 is consistent, avoiding the shear force on the coupling bolts at the traction motor 3 and the gear box 4, thereby damaging the bolts and the coupling. At the same time, the rubber pad has a soft property to achieve an anti-slip function.

[0051] It should be noted that the positioning components of the support assemblies on both sides are arranged opposite to each other, or the positioning components of the support assemblies on both sides are placed on the same side of the horizontal direction of the parts to be installed. At this time, after the positioning components on both sides locate the positions of the parts to be installed, it is convenient for the subsequent rapid adjustment of the components.

[0052] Considering that the components on one side are positioned by the lateral shock absorber seat 6 of the bogie 1, two light emitters are arranged at the support assembly on the same side of the lateral shock absorber seat 6 of the bogie 1, and the positions of the two light emitters are different.

[0053] In this embodiment, reference Figure 10 and Figure 11 As shown, the positioning component 22 is L-shaped, the first side of the positioning component 22 is placed on the end side of the component, and the second side of the positioning component 22 is placed on the side side of the component. The L-shaped positioning component 22 can position one end of the traction drive device, wherein the first light emitter 23 is provided on the first side of the positioning component 22, and the second light emitter 24 is provided on the second side of the positioning component 22. The first light emitter 23 located on the first side of the positioning component 22 is lower than the connection between the traction motor 3 and the gear box 4 in the traction drive device, because the light beam emitted by the first light emitter 23 will not be blocked here, so that the light beam can reach the end of the lateral vibration damper seat. In this way, after the positioning of the component on one side is completed by the first light emitter 23, the component on the other side is accurately positioned by the second light emitter 24.

[0054] It is easy to understand that the light beam emitted by the first light emitter 23 is directed toward the lateral vibration damper seat 6, and a cross point is set at the center of the lateral vibration damper seat 6 to ensure that the light beam emitted by the first light emitter is aligned with the center of the lateral vibration damper seat 6.

[0055] A light receiver 25 is provided on the positioning component of the support assembly on the other side. The position of the light receiver 25 on the corresponding side positioning component 22 is the same as the position of the positioning component where the emission point of the second light emitter 24 is located. The width of the light receiver 25 is adapted to the width of the emission point of the second light emitter 24. As long as the light receiver can receive the light beam signal, the light receiver is connected to the controller. The controller is a PLC controller or other types of controllers. The controller is installed on the side of the bottom platform. The controller is respectively connected to the X-axis linear slide, Y-axis linear slide, and two light emitters in the support assemblies on both sides. The two light emitters are controlled by the controller to work. If the controller does not receive the feedback signal from the light receiver, the controller will control the X-axis linear slide on the other side to continue moving. After receiving the signal from the light receiver, the controller indicates that the position of the component at the corresponding side support assembly has been accurately positioned and there is no need to control the X-axis linear slide.

[0056] In this embodiment, the light transmitter can be a laser transmitter, and the light receiver can be an existing laser receiver.

[0057] In addition, considering the preliminary Y-direction positioning of the traction drive device 2 relative to the bogie 1, positioning blocks are set on the ground on both sides of the part to be installed, such as the bogie, to position the wheels on both sides. In this way, the setting of the positioning component 22 can achieve the preliminary Y-direction positioning of the traction drive device 2 relative to the bogie 1, ensuring that the subsequent movement of the traction drive devices 2 on both sides is synchronized.

[0058] The support device provided in this embodiment first supports the traction drive device 2 through the support assembly, and preliminarily positions the component through the positioning component. After the positioning is completed, the support assembly is moved to the side of the bogie 1 in the longitudinal direction, and the traction drive device on the side of the support assembly where it is located is accurately positioned by the first light emitter 23, and then the traction drive device on the other side is accurately positioned by the second light emitter 24. After the accurate positioning, the support assemblies on both sides are moved at the same time to realize the simultaneous installation of the traction drive devices on both sides. The overall accurate positioning of the component can be quickly realized, effectively improving the positioning efficiency and installation efficiency.

[0059] Example 2 This embodiment discloses a method for disassembling and assembling a traction drive device, using the support device for component disassembly and assembly described in the first embodiment, and includes the following contents: When working, the bottom end of the support leg locking member 14 is fully in contact with the ground and locked, so that the center of gravity of the workpiece is within the working range of the support leg locking member 14; The support assembly supports the traction drive device 2 through the upper platform and positions the traction drive device 2 through the positioning component; Each support assembly drives the traction drive device 2 to move to both sides of the bogie 1 in the longitudinal direction; The first light emitter 23 emits a light beam toward the transverse damper seat 6 of the bogie 1. The point where the light beam is received on the transverse damper seat 6 is used to determine whether the traction drive device on one side is aligned with the transverse damper seat. If aligned, the controller does not need to control the X-direction linear slide rail on that side to continue moving. If not aligned, the controller needs to continue controlling the X-direction linear slide rail on that side to move until they are aligned. After the calibration is completed, the second light emitter 24 emits a light beam toward the positioning component of the other side support assembly. The positioning component on this side is provided with a light receiver 25. If the controller does not receive the feedback signal from the light receiver 25, the controller will control the X-axis linear slide on the other side to continue moving. After the controller receives the signal from the light receiver, it means that the position of the component at the corresponding side support assembly has been accurately positioned and there is no need to control the X-axis linear slide anymore. After the adjustment is completed, the positioning of the traction drive devices on both sides is achieved, and the controller controls the Y-axis linear slide rails on both sides to move simultaneously to drive the traction drive device to move toward the bogie at the same time to complete the installation of the traction drive device.
