Description

Technical Field

[0001] This application relates to the field of wheelset placement technology, and in particular to wheelset placement devices. Background Technology

[0002] The wheelset motor is one of the ten major components of an electric locomotive bogie and serves as the locomotive's drive unit. When a wheelset motor malfunctions, it needs to be removed for replacement and repair. The removed wheelset motor then needs to be transported or stored. High levels of protection are required for wheelsets and wheelset motors during hoisting, storage, and transportation.

[0003] In the past, wheelset motors required many auxiliary tools for transportation or placement, which was time-consuming and labor-intensive. Moreover, after setting up wheelset fixing devices and motor fixing devices, the overall size of the placement device was large and occupied a large area, resulting in low transportation and loading / unloading efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a wheelset placement device to address the problem of low transportation and loading / unloading efficiency of existing wheelset placement devices.

[0005] A wheelset placement device includes a base frame with a rectangular frame structure and a motor base. The base frame includes two vertical bars extending in a first direction and arranged in parallel, and two horizontal bars extending in a second direction and arranged in parallel.

[0006] Each of the two vertical rods is provided with a wheelset base, and the top of each wheelset base is provided with a groove for placing the wheel in the wheelset;

[0007] A limiting rod is also provided between the two vertical rods, extending along the first direction and connected at both ends to the two horizontal rods respectively;

[0008] The motor base is rotatably mounted on one of the crossbars. The motor base is provided with a support plate. The motor base has an unfolded position and a folded position. When the motor base is in the unfolded position, the support plate is located on top of the motor base and is used to support the wheelset motor. When the motor base is rotated to the folded position by a set angle, the support plate abuts against the limiting rod.

[0009] In one embodiment, the motor base is further provided with a base plate, and the base plate and the support plate are disposed opposite to each other on both sides of the motor base. When the motor base is in the unfolded position, the base plate is parallel to the ground and abuts against the ground.

[0010] In one embodiment, a buffer layer is provided at the bottom of the bottom frame.

[0011] And / or, the tray is provided with a buffer layer,

[0012] And / or, the base plate is provided with a buffer layer,

[0013] And / or, the wheelset base is provided with a buffer layer.

[0014] In one embodiment, the groove is an arc-shaped groove that matches the shape of the wheel in the wheelset.

[0015] In one embodiment, the bottom frame is provided with a stabilizer, at least a portion of which is attached to the side wall of the wheelset base and fixedly connected to the wheelset base.

[0016] In one embodiment, at least three lifting rings are arranged on the bottom frame.

[0017] In one embodiment, a locking structure is provided at the rotatable connection between the motor base and the crossbar. When the motor base is in the unfolded position and / or the folded position, the locking structure is used to lock or unlock the motor base and the crossbar.

[0018] In one embodiment, at least two of the wheelset placement devices are stacked vertically, one of two adjacent wheelset placement devices is rotated 180 degrees vertically, and the limiting rod in the upper wheelset placement device is positioned close to one of the vertical rods to avoid the motor mount in the lower wheelset placement device.

[0019] In one embodiment, the pallet is provided with a motor slot for accommodating at least a portion of the wheelset motors. In the first direction, the motor slot is disposed opposite to the limiting rod. When the motor seat is in the folded position, at least a portion of the limiting rod is located within the motor slot.

[0020] Furthermore, based on the aforementioned motor slot design, the limiting effect of the tray on the wheelset motor can be improved, further enhancing the stability of the wheelset motor on the wheelset placement device. Moreover, when the motor mount rotates to the folded position, because the motor slot and the limiting rod are positioned opposite each other, part of the limiting rod can be located within the motor slot, thereby increasing the rotation angle of the motor mount. In other words, the apex height of the motor mount when rotated to the folded position is lower, further preventing interference with the stacking operation of the wheelset placement device.

[0021] In one embodiment, the motor base includes a swing arm and a motor bracket, one end of the swing arm being rotatably connected to the crossbar and the other end being connected to the motor bracket;

[0022] When the motor base is in the unfolded position, the support plate is located on top of the motor bracket, and the swing arm is set parallel to the ground;

[0023] When the motor base is in the folded position, the limiting rod, the swing arm, and the motor bracket form a triangular avoidance area.

[0024] Furthermore, based on the aforementioned motor mount, the swing arm can extend in the first direction to ensure that the pallet is located directly below the wheelset motor and to reliably and stably support the wheelset motor. At the same time, the triangular clearance area formed by the combination of the swing arm, motor bracket, and limit rod when rotated to the folding position allows the top of the lower motor mount to avoid the side of the limit rod and continue to move upward to the triangular clearance area, thereby reducing the total height of the stacked multiple wheelset placement devices.

[0025] The aforementioned wheelset placement device, through the motor mount, stably supports and secures the motor within the wheelset. Combined with the wheelset base, it reliably supports and secures both the wheels and the motor simultaneously, improving the stability of the wheelset on the placement device. The motor mount, which can be switched between an unfolded and folded position, allows for deployment depending on the use of the wheelset placement device. When not in use, the folded motor mount significantly reduces the space occupied by the wheelset placement device, facilitating transportation and storage. When in use, the device can be easily unfolded by simply rotating the motor mount, without the need for auxiliary tools. When the motor mount is in the folded position, the device can also be used to place wheelsets without motors, saving space and ensuring stable wheelset mounting. Attached Figure Description

[0038] This application provides a wheelset placement device that stably supports and secures the motor in the wheelset through a motor mount. Combined with a wheelset base, it reliably supports and secures both the wheels and the motor simultaneously, improving the stability of the wheelset on the placement device. The motor mount, which can be switched between an unfolded and folded position, allows for deployment depending on the use of the wheelset placement device. When not in use, the folded motor mount significantly reduces the space occupied by the wheelset placement device, facilitating transportation and storage. When in use, the device can be easily unfolded by simply rotating the motor mount, without the need for auxiliary tools. When the motor mount is in the folded position, the device can also be used to place wheelsets without motors, saving space and ensuring stable wheelset mounting.

[0039] The present application will be described in detail below through specific embodiments.

[0040] Reference Figures 1 to 3As shown, this embodiment provides a wheelset placement device, including a rectangular frame base 1 and a motor mount 2. The base frame 1 includes two vertical rods 11 extending in a first direction and arranged in parallel, and two horizontal rods 12 extending in a second direction and arranged in parallel. Each of the two vertical rods 11 is provided with a wheelset base 13, and the top of each wheelset base 13 is provided with a groove 131 for placing the wheels in the wheelset; a limiting rod 14 extending in the first direction and connected to the two horizontal rods 12 at both ends is also provided between the two vertical rods 11. The motor mount 2 is rotatably mounted on one of the horizontal rods 12. The motor mount 2 is provided with a support plate 21. The motor mount 2 has an unfolded position and a folded position. When the motor mount 2 is in the unfolded position, the support plate 21 is located on the top of the motor mount 2 and is used to support the wheelset motor. That is, at this time, the support plate 21 is at a certain distance from the ground and matches the height of the bottom of the motor on the wheelset. When the motor mount 2 is rotated to the folded position by a set angle, the support plate 21 abuts against the limiting rod 14.

[0041] The wheelset placement device provided in this embodiment can stably support and fix the motor in the wheelset through the setting of the motor mount 2. Together with the wheelset base 13, it can reliably support and fix both the wheels and the motor in the wheelset simultaneously, improving the stability of the wheelset on the wheelset placement device. The motor mount 2, which can be switched between an unfolded and folded position, can be unfolded or folded according to the usage of the wheelset placement device. When the wheelset placement device is not in use, the folded motor mount 2 significantly reduces the space occupied by the wheelset placement device, thus facilitating its transportation and storage. When the wheelset placement device is in use, it can be unfolded simply by rotating the motor mount 2 without the need for auxiliary tools. When the motor mount 2 is moved to the folded position, the wheelset placement device can also be used to place wheelsets without motors, saving space and ensuring the stability of the wheelset fixation.

[0042] In some embodiments, the motor mount 2 is further provided with a base plate 22, and the base plate 22 and the support plate 21 are disposed opposite each other on both sides of the motor mount 2. When the motor mount 2 is in the unfolded position, the base plate 22 is parallel to the ground and abuts against the ground. It should be noted that the base plate 22 can increase the contact area between the motor mount 2 and the ground, thereby providing a more stable support structure for the wheelset motor and improving the reliability of the wheelset placement device.

[0043] In some embodiments, a buffer layer is provided at the bottom of the base frame 1, and / or a buffer layer is provided on the support plate 21, and / or a buffer layer is provided on the base plate 22, and / or a buffer layer is provided on the wheelset base 13. It should be understood that the buffer layer can be a rubber pad with anti-slip effect, thereby protecting the base frame 1, support plate 21, base plate 22, and wheelset base 13, while also protecting the wheels and motor in the wheelset and the ground, reducing bump damage during the placement or transportation of the wheelset. Anti-slip textures can also be provided on the buffer layer to further improve the stability of the wheelset placement device on the ground, as well as the stability of the wheelset placed on the wheelset placement device.

[0044] Continue to refer to Figure 1 and Figure 2 As shown, the groove 131 is an arc-shaped groove that matches the shape of the wheel in the wheelset. That is, the diameter of the groove 131 is the same as the diameter of the wheel, thereby reducing the wobbling of the wheel when it is placed in the groove 131. The inner wall of the groove 131 is close to the wheel, which can provide reliable support for the wheel while preventing the wheel from easily rolling along the inner wall of the groove 131 under its own weight.

[0045] In some embodiments, a stabilizing member is provided on the base frame 1, at least part of which is in contact with the side wall of the wheelset base 13 and fixedly connected to the wheelset base 13. The stabilizing member may be a concave structure, with the wheelset base 13 inserted into it from top to bottom and then fixedly connected to the stabilizing member by bolts or other structures. This further limits the circumference of the wheelset base 13, thereby further improving the support stability of the wheelset base 13 for the wheels in the wheelset.

[0046] Continue to refer to Figures 1 to 3 As shown, at least three lifting rings 15 are arranged on the base frame 1. It should be understood that when there are three lifting rings 15, they can be arranged in a triangular pattern on the base frame 1; when there are four lifting rings 15, they can be arranged in a rectangular pattern on the base frame 1. Specifically, the lifting rings 15 can be placed on the crossbar 12 to avoid interfering with the position of the wheelset base 13. The arrangement of the lifting rings 15 facilitates the hoisting of the wheelset placement device, thereby improving transportation efficiency.

[0047] Furthermore, the height of the lifting ring 15 is not higher than the highest point of the wheelset base 13 to avoid affecting the stacking of multiple wheelset placement devices.

[0048] In some embodiments, a locking structure is provided at the rotatable connection between the motor base 2 and the crossbar 12. When the motor base 2 is in the unfolded position and / or folded position, the locking structure is used to lock or unlock the motor base 2 and the crossbar 12. Specifically, the locking structure may be a locking pin. When the motor base 2 rotates to the unfolded or folded position, the locking pin is inserted to lock and fix the relative position and relative angle between the motor base 2 and the crossbar 12. The locking structure may also be other structures capable of fixing the rotatable connection between the motor base 2 and the crossbar 12, such as a brake, etc., which are not limited here.

[0049] Continue to refer to Figure 3 As shown, at least two wheel set placement devices are stacked vertically. One of the two adjacent wheel set placement devices is rotated 180 degrees vertically. The limiting rod 14 in the upper wheel set placement device is positioned close to one of the vertical rods 11 to avoid the motor mount 2 in the wheel set placement device below it. In other words, by rotating the bottom frame 1 of one of the two stacked wheel set placement devices 180 degrees in the horizontal plane, the limiting rods 14 of the upper and lower layers are staggered to avoid the motor mount 2 of the lower layer. This arrangement can reduce the overall height of the wheel set placement device while enabling the stacking of multiple wheel set placement devices, further improving the transportation efficiency of the wheel set placement device and the space occupied by multiple wheel set placement devices when not in operation.

[0050] In some embodiments, the tray 21 is provided with a motor slot for accommodating at least a portion of the wheelset motors. In a first direction, the motor slot is disposed opposite to the limiting rod 14. When the motor seat 2 is in the folded position, at least a portion of the limiting rod 14 is located within the motor slot. The motor slot enhances the limiting effect of the tray 21 on the wheelset motors, further improving the stability of the wheelset motors on the wheelset placement device. Furthermore, when the motor seat 2 is rotated to the folded position, since the motor slot and the limiting rod 14 are disposed opposite to each other, a portion of the limiting rod 14 can be located within the motor slot, thereby increasing the rotation angle of the motor seat 2. In other words, the apex height of the motor seat 2 when rotated to the folded position is lower, further preventing interference with the stacking operation of the wheelset placement device.

[0051] Continue to refer to Figures 1 to 3 As shown, in some embodiments, the motor base 2 includes a swing arm 23 and a motor bracket 24. One end of the swing arm 23 is rotatably connected to the crossbar 12, and the other end is connected to the motor bracket 24. When the motor base 2 is in the unfolded position, the support plate 21 is located on top of the motor bracket 24, and the swing arm 23 is parallel to the ground. When the motor base 2 is in the folded position, the limiting rod 14, the swing arm 23, and the motor bracket 24 form a triangular clearance area.

[0052] Furthermore, based on the aforementioned motor base 2, the swing arm 23 can extend in the first direction to ensure that the support plate 21 is located directly below the wheelset motor and to reliably and stably support the wheelset motor. At the same time, the triangular clearance area formed by the combination of the swing arm 23, the motor bracket 24, and the limiting rod 14 when rotated to the folded position allows the top of the lower motor base 2 to avoid the side of the limiting rod 14 and continue to move upward to the triangular clearance area, thereby reducing the total height of the stacked multiple wheelset placement devices.

[0053] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments, the top surface of the wheelset base 13 is provided with a flat portion 132, that is, both ends of the groove 131 are provided with a flat portion 132. Through the four flat portions 132 on the two wheelset bases 13, four planar fulcrums are formed, realizing the stacking of at least two wheelset placement devices and improving the stability of the wheelset placement devices when stacked.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
