[0038] As introduced in the background art, there is a problem that the disassembly process of gearbox components in the prior art is relatively complex. To solve the above technical problems, the present invention proposes a support device for disassembling and lifting a gearbox of a rail vehicle.

[0039] Embodiment 1

[0040] In a typical implementation manner of the present invention, referring to Figure 1 As shown, a support device for disassembling and lifting a gearbox of a rail vehicle includes a base 1. The base 1 supports a wheel seat support member 2, a journal support member 3, and a gearbox seat support member 4. The base 1 is provided with a moving mechanism. The bottom or side of the gearbox seat support member is connected to the moving mechanism. The moving mechanism includes a first moving component to drive the gearbox seat support member to move towards the axle direction. At least one of the wheel seat support member 2 and the journal support member 3 is liftable. The gearbox seat support member 4, the wheel seat support member 2, and the moving mechanism are respectively connected to the controller independently. The wheel seat support member 2 and the journal support member 3 are respectively provided with a distance measuring sensor, and the distance measuring sensor is connected to the controller.

[0041] To ensure stable support for the gearbox with an axle, there are two journal support members (for supporting the end side of the axle) 3 and two wheel seat support members (for supporting the thicker position on the inner side of the axle journal, i.e., where the wheel set is installed) 2. The journal support member 3 is located outside the wheel seat support member 2. The journal support member is arranged at a set distance from the nearest wheel seat support member. The gearbox seat support member 4 is located outside the space between the two wheel seat support members.

[0042] In this embodiment, the base 1 is a frame-shaped base with a set length and width. The opposite sides of the frame-shaped base are respectively provided with wheel seat support members. The frame-shaped base is provided with connecting plates on the outside of the wheel seat support members, and the connecting plates are connected to the housing of the journal support member.

[0043] Reference Figure 1 As shown, the first moving component includes a first support plate 4-2. The first support plate 4-2 is fixed to the side of the base 1. The first linear guide 4-3 is arranged on the surface of the first support plate. The first moving block of the first linear guide is connected to the gearbox seat support member 4 to drive the movement of the gearbox seat support member. The first linear guide is a prior art.

[0044] In this embodiment, the gearbox seat support member 4 includes a support column 4-4. A support pad 4-1 is arranged at the top of the support column 4-4. The support pad can be a circular support pad. The support pad is connected to the support column through a threaded structure. Specifically, a screw rod 4-5 is arranged on the side of the support pad facing the support column, and the screw rod 4-5 is connected to the opening of the support column through a threaded structure, so as to adjust the height of the support pad relative to the support column. A rubber pad can be arranged on the surface of the support pad.

[0045] Reference Figure 2 As shown, the wheel seat support member 2 includes a portal bracket 2-2. The two sides of the portal bracket can be inclined. A first support portion is arranged at the top of the portal bracket 2-2.

[0046] The first support portion includes a pair of rollers 2-1. The distance between the two rollers 2-1 is set. The rollers are rotatably arranged relative to the top end of the first lifting rod. A pair of mounting plates 2-3 are arranged at the top of the portal bracket. The roller shaft of the roller is supported by the mounting plates 2-3. The roller is rotatable relative to the mounting plates, and the thicker position of the axle is stably supported by the pair of rotatable rollers.

[0047] In this embodiment, the journal support member 3 is liftable. The journal support member 3 includes a second lifting rod. A second support portion is arranged at the movable end of the second lifting rod to support the journal part of the axle. The second lifting rod can be a lifting oil cylinder. The top of the lifting oil cylinder is provided with the second support portion. The lifting oil cylinder is placed in the housing, and the housing is supported by the base 1. The telescopic rod of the lifting oil cylinder passes through the top side of the housing and is connected to the second support portion.

[0048] In some examples, a second ranging sensor can be set at a position on the top side of the shell lower than the second support part. The second ranging sensor obtains the height change of the second support part and sends the obtained information to the controller. The controller is connected to the second lifting rod. After the height of the second support part reaches the set height, the controller controls the second lifting rod to stop moving; moreover, the second lifting rods of the journal support components on both sides are raised and lowered synchronously, and the controller controls the two second lifting rods synchronously.

[0049] It is easy to understand that the controller is a PLC controller or other types of controllers, the second ranging sensor can be an ultrasonic ranging sensor, and of course it can also be other types of ranging sensors. The controller can be placed in the shell, and a switch can be set at 3-2 of the shell. The switch is connected to the power supply. After the switch is turned on, the controller controls the lifting and lowering of the second lifting rod.

[0050] In addition, the controller is connected to the remote controller via a wireless signal, and the remote controller can send a signal to the controller, which can be used to control the lifting action of the second lifting rod via the remote controller.

[0051] In this embodiment, reference Figure 3 As shown, the second support portion includes an arc-shaped support seat 3-1, which is fixed to the top of the second lifting rod. The arc-shaped support seat 3-1 is adapted to the axle to ensure stable support for the axle; the arc-shaped mounting seat has a set width, and the arc of the arc-shaped mounting seat is slightly larger than the arc of the bottom side of the axle. Figure 4 As shown, a protruding plate 3-3 is provided on the side of the arc-shaped mounting seat, and the protruding plate can be a flat plate. The measuring head of the second distance measuring sensor can be placed under the protruding plate to facilitate accurate acquisition of data.

[0052] The support device provided in this embodiment comprises a base 1 supporting a wheel seat support member, a journal support member and a gear box seat support member. The wheel seat support member is used to support the wheel seat portion of the gear box with an axle, the journal support member is used to support the journal position of the axle, and the gear box seat support member is used to support the gear box with an axle. In the initial state, the arc-shaped support seat 3-1 is arranged higher than the roller 2-1 under the action of the second lifting rod. Thus, the gear box with an axle is supported at multiple points to ensure smooth disassembly of the gear box. After the bolts of the bearing cover and the sealing cover are loosened, and the collector ring and the oil retaining ring are thermally retreated, the arc-shaped support seat in the wheel seat support member is lowered to expose the space on the side of the gear box. The corresponding components can be extracted from the axle without lifting the axle by an overhead crane. The entire device is reliable and stable. The device can meet the requirements for disassembly, support and lifting of various types of gear box components with axles, thereby ensuring the reliability of the gear box during the inspection and maintenance of the rail vehicle.

[0053] Embodiment 2

[0054] The difference between this embodiment and the first embodiment is as follows:

[0055] In this embodiment, the moving mechanism further includes a second moving component, which is connected to the first moving component. The moving direction of the second moving component is perpendicular to that of the first moving component, so as to drive the gearbox seat support member to move in a direction parallel to the axle.

[0056] Specifically, the second moving component includes a second support plate fixed to the first linear guide rail. The second support plate is provided with a second linear guide rail. The second moving block of the second linear guide rail is fixed at the first moving block, and the second moving block is connected to the support column in the gearbox seat support member;

[0057] Similarly, the second linear guide rail is an existing linear guide rail.

[0058] Embodiment Three

[0059] The difference between this embodiment and the first embodiment is as follows:

[0060] In this embodiment, the wheel seat support member 2 is liftable. The wheel seat support member 2 includes a first lifting rod. The movable end of the first lifting rod is provided with a first support portion to support the wheel seat part of the axle. The first lifting rods of the two side wheel seat support members are lifted and lowered synchronously, and the controller synchronously controls the two first lifting rods;

[0061] The fixed end of the first lifting rod is provided with a first distance sensor, and the first distance sensor acquires the height change of the first support portion at the movable end of the first lifting rod and sends it to the controller.

[0062] In this embodiment, the first lifting rod is arranged at the top of the gantry bracket. The first lifting rod can be a lifting oil cylinder. The movable end of the lifting oil cylinder is provided with a flat plate, and a pair of rollers are arranged on the upper side of the flat plate; thus, the first distance sensor is arranged at the top of the gantry bracket, and the distance sensor is arranged lower than the flat plate. The height change of the first support portion is obtained by the height of the flat plate higher than the gantry bracket.

[0063] After each component of the gearbox is disassembled, the first lifting rod drives the axle to rise through the first support portion and exceeds the arc-shaped support seat, so that a space is exposed on the side of the gearbox, and the corresponding component is taken off from the side of the axle.

[0064] Embodiment Four

[0065] The difference between this embodiment and the first embodiment is as follows:

[0066] The wheel seat support member and the journal support member can both be set to be liftable. Specifically, for the lifting method, the lifting is carried out in the manner of Embodiment 1 and Embodiment 3 of the installation, and the controller synchronously controls the first lifting rod and the second lifting rod. Specifically, after the bolts of each component of the gearbox are loosened and the slip ring and the oil baffle ring are thermally retreated, both the first lifting rod and the second lifting rod rise. The rising height of the first lifting rod is greater than the lifting height of the second lifting rod, and thus the disassembly space can be exposed.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
