DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0038] The core of the present invention is to provide a bogie wheel replacement and line transfer device, which enables workers to complete the disassembly of the wheel set device and the transfer and line transfer of the frame on the ground, with convenient and safe operation.

[0039] Please refer to Figures 1-6 .

[0040] The bogie wheel replacement and line transfer device provided by the present invention includes:

[0041] A bogie lifting device 1 for supporting and lifting the wheel set device of the bogie;

[0042] A frame lifting device 2 for supporting and lifting the frame of the bogie;

[0043] A pit track 4 which is connected to both the first production line 01 and the second production line 02;

[0044] A transfer cart 3 for moving along the pit track 4 to drive the bogie to change lines, and the bogie lifting device 1 and the frame lifting device 2 are provided thereon;

[0045] A control device 8 which is signal-connected to the bogie lifting device 1, the frame lifting device 2 and the transfer cart 3.

[0046] Among them, the first production line 01 is mainly used for the disassembly of the wheel set device of the bogie, the second production line 02 is mainly used for the disassembly of the bogie frame after the wheel set device is removed, and the pit track 4 is connected to both the first production line 01 and the second production line 02 at the same time;

[0047] To facilitate the movement of the transfer cart 3 in the pit track 4, the pit track 4 is usually set to be vertically connected between the first production line 01 and the second production line 02, as Figure 1 shown.

[0048] When the frame of the bogie changes lines, the transfer cart 3 drives the frame to move along the pit track 4, so that the frame is transferred from the first production line 01 to the second production line 02. Compared with the existing hoisting and line transfer method, the pit track 4 avoids the worker operation area and avoids the falling safety risk brought by the hoisting operation, effectively improving the safety of the operation environment.

[0049] Preferably, the height of the transfer cart 3 can be set to be lower than or equal to the depth of the pit track 4, so that workers can stand on the ground to disassemble the wheel set device of the lifted bogie.

[0050] The height of the transfer cart 3, the depth of the pit track 4 and the lifting range of the bogie lifting device 1 should be determined according to the size of the bogie in actual production, etc., so that the disassembly height of the bogie meets the requirements of ergonomics, thereby reducing the fatigue degree of workers when disassembling the wheel set device.

[0051] The transfer cart 3 is provided with a bogie lifting device 1 and a frame lifting device 2 for driving the frame to move along the pit track 4 to realize the line transfer operation of the frame. The specific type, structure and size of the transfer cart 3 are determined according to the structure and size of the bogie in actual production, etc., and its moving part can refer to the existing frame transfer cart, etc.

[0052] Preferably, the pit track 4 can be provided with a guide rail 41 for engaging and cooperating with the wheels of the transfer cart 3, and the guide rail 41 is arranged along the extending direction of the pit track 4. Therefore, the movement of the transfer cart 3 along the extending direction of the pit track 4 can be restricted by the guide rail 41, avoiding the deviation of the transfer cart 3 and thus preventing the transfer cart 3 from rubbing or colliding with the inner wall surface of the pit track 4.

[0053] The specific quantity, structure, size and distribution of the guide rail 41 are determined according to the quantity, structure, size and distribution of the wheels of the transfer cart 3 in actual production, which will not be elaborated here.

[0054] The bogie lifting device 1 and the frame lifting device 2 are respectively used to drive the wheel set device of the bogie and the frame to move along the height direction of the pit track 4, and their fixed ends are both connected to the transfer cart 3;

[0055] The moving end of the wheel set lifting mechanism is provided with a wheel set fixing groove for engaging with the outer rail surface of the wheel set device to support the wheel set device; the fixed end of the frame lifting device 2 is connected to the transfer cart 3, and the moving end is provided with a frame fixing groove for engaging with the frame to support the frame.

[0056] Both the bogie lifting device 1 and the frame lifting device 2 can be set as common linear displacement mechanisms such as hydraulic cylinders, electric push rods, ball screw mechanisms, etc. Their specific types, structures and sizes are determined according to the needs of actual production, which will not be elaborated here.

[0057] The bogie lifting device 1, the frame lifting device 2 and the transfer cart 3 are all signal-connected to the control device 8, so that the control device 8 can control the lifting of the wheel set device, the lifting of the frame and the movement of the frame along the pit track 4.

[0058] During use, first, the bogie to be disassembled is pushed in manually or mechanically, and the wheel set device of the bogie is placed into the bogie lifting device 1; the control device 8 controls the bogie lifting device 1 to lift the bogie to the disassembly height; disassemble components such as axle box bolts to loosen the connection between the wheel set device and the frame; the control device 8 controls the frame lifting device 2 to rise, and uses the frame lifting device 2 to support the frame of the bogie; the control device 8 controls the bogie lifting device 1 to drive the wheel set device to descend, so that the wheel set device is separated from the frame, and then the wheel set device is pushed out manually or mechanically.

[0059] After the separation of the wheel set device is completed, the control device 8 drives the transfer cart 3 to move along the pit track 4, driving the transfer cart 3 to move from the connection point of the pit track 4 and the first production line 01 to the connection point of the pit track 4 and the second production line 02, and then a frame transfer cart is pushed in manually or mechanically; the control device 8 controls the frame lifting mechanism 2 to descend, so that the frame falls into the component transfer vehicle on the second production line 02; the control device 8 drives the transfer cart 3 to move along the pit track 4, driving the transfer cart 3 to return to its original position.

[0060] In this embodiment, the bogie wheel replacement and line transfer device integrates the bogie lifting device 1, enabling workers to disassemble the wheel set device under the bogie, saving time and effort in operation; the setting of the transfer cart 3 and the pit track 4 allows workers to complete the transfer and line change operation of the frame on the ground. Compared with the existing hoisting operation method, it does not require special operation qualifications and is safer in operation.

[0061] Based on the above embodiment, in order to prevent workers from accidentally falling into the pit track 4, the bogie wheel replacement and line transfer device may further include:

[0062] A pit cover plate 5 for closing the pit track 4, which is provided with an installation hole for the transfer cart to reserve the installation space for the transfer cart 3;

[0063] A cover plate drive assembly, whose output end is connected to the pit cover plate 5;

[0064] A cover plate motor 7, whose output shaft is connected to the input end of the cover plate drive assembly;

[0065] The control device 8 is signal-connected to the cover plate motor 7 to control the cover plate motor 7 to drive the pit cover plate 5 to move synchronously with the transfer cart 3 along the pit track 4.

[0066] Please refer to Figure 1 , the opening end of the pit track 4 is provided with a pit cover plate 5 to close the pit track 4 through the pit cover plate 5; in order to prevent the pit cover plate 5 from hindering the movement of the transfer cart 3 along the pit track 4, the control device 8 controls the cover plate motor 7 to drive the pit cover plate 5 to move synchronously with the transfer cart 3 along the pit track 4.

[0067] It should be noted that considering the installation space required for the cover plate drive assembly and the cover plate motor 7, in order to avoid the cover plate drive assembly and the cover plate motor 7 interfering with the movement of the transfer cart 3, the length of the pit track 4 is usually set to be greater than the horizontal distance from the first production line 01 to the second production line 02.

[0068] The pit cover plate 5 can only cover the opening end of the pit track 4 or can be arranged around the pit track 4; the cover plate drive assembly is determined according to factors such as the structure of the pit cover plate 5 and the installation position of the cover plate motor 7, and it can specifically be set as a sprocket drive assembly, a gear and rack drive assembly, etc.

[0069] When the pit cover plate 5 only covers the opening end of the pit track 4, the pit cover plate 5 can be divided into two sections, and the two sections of the pit cover plate 5 are respectively arranged in front of and behind the moving direction of the transfer cart 3. The two sections of the pit cover plate 5 can be driven by two cover plate motors 7 respectively, or can be driven by one cover plate motor 7 using a cover plate drive assembly arranged along the extension direction of the pit track 4.

[0070] When the pit cover plate 5 is arranged around the pit track 4, the pit cover plate 5 winds around the bottom surface of the pit track 4 and the side surfaces at both ends of the extending direction. By setting a single cover plate motor 7, the pit cover plate 5 in front of and behind the transfer cart 3 can be driven to rotate. The cover plate transmission assembly has a simple structure, occupies less space, and causes less interference to the movement of the transfer cart 3.

[0071] To simplify the structure of the cover plate transmission assembly, preferably, the pit cover plate 5 can be arranged around the pit track 4, and the pit cover plate 5 is flush with the open end of the pit track 4.

[0072] Considering that the pit cover plate 5 needs to wind around the included angle between the side surface and the open end of the pit track 4, the pit cover plate 5 is usually set as a flexible plate surface. For example, Figure 6 the pit cover plate 5 shown in the figure, which is bent and formed from a light aluminum alloy middle plate.

[0073] In this embodiment, the pit cover plate 5 covers the open end of the pit track 4 and can move synchronously with the transfer cart 3, taking into account the needs of closing the pit track 4, preventing personnel from accidentally falling, and ensuring the normal line change movement of the transfer cart 3, thereby improving production safety.

[0074] Considering that the overall length of the pit cover plate 5 is relatively long, preferably, the number of cover plate motors 7 can be set to two, and the two cover plate motors 7 are respectively arranged at both ends of the pit track 4 in the length direction, as Figure 1 shown in the figure.

[0075] On the basis of the above embodiment, the cover plate transmission assembly is defined. The cover plate transmission assembly includes:

[0076] A driving sprocket 61, sleeved on the output shaft of the cover plate motor 7;

[0077] A chain 62 meshing with the driving sprocket 61, which is connected to the bottom surface of the pit cover plate 5.

[0078] The type and distribution of the chain 62 should consider the material and bearing capacity requirements of the pit cover plate 5, so as to prevent the edge of the pit cover plate 5 from drooping downward, resulting in a drop between the upper end surface of the pit cover plate 5 and the open end of the pit track 4.

[0079] Preferably, chains 62 can be arranged on both sides of the pit cover plate 5, and the chains 62 are bolted to the pit cover plate 5, so that the pit cover plate 5 has a high bearing capacity on both sides in the moving direction of the transfer cart 3.

[0080] Please refer to Figure 4 , the chain 62 is usually set as an ear chain. The ear plate (chain bracket) of the chain 62 is connected to the bottom surface of the pit cover plate 5 through fasteners such as fastening bolts. On the one hand, it can connect the chain 62 and the pit cover plate 5, and on the other hand, it can play a supporting role for the pit cover plate 5.

[0081] The driving sprocket 61 is sleeved on the output shaft of the cover plate motor 7. When the control device 8 controls the rotation of the cover plate motor 7, the driving sprocket 61 rotates with the output shaft of the cover plate motor 7, and then drives the chain 62 engaged with it to move in the rotation direction of the driving sprocket 61, and finally drives the pit cover plate 5 to move synchronously with the transfer cart 3 along the direction of the pit track 4.

[0082] The driving sprockets 61 and the chains 62 are arranged in one-to-one correspondence. If only one chain 62 is provided on the bottom surface of the pit cover plate 5, one driving sprocket 61 is sleeved on the output shaft of the cover plate motor 7; if two chains 62 are provided on the bottom surface of the pit cover plate 5, two driving sprockets 61 are sleeved on the output shaft of the cover plate motor 7, and the two driving sprockets 61 sleeved on the output shaft of the same cover plate motor 7 are regarded as a group of driving sprockets 61.

[0083] In a specific embodiment, two groups of driving sprockets 61 and two groups of tensioning sprockets are respectively provided at the four corners of the pit track 4. The two groups of tensioning sprockets are arranged at the lower part of the pit track 4, and the two groups of tensioning sprockets are arranged at the upper part of the pit track 4; the two groups of driving sprockets 61 are respectively driven by two cover plate motors 7, and the front and rear double-driving mode is beneficial to the stable transportation of the pit cover plate 5.

[0084] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0085] The above has introduced the bogie wheel-changing and line-switching device provided by the present invention in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
