[0039] Example 1

[0040] Depend on Figure 1 —6 It can be seen that an embodiment of the utility model provides an auxiliary disassembly tool for the bottom of an EMU, including a moving unit 1 for controlling the overall movement of the tool, a bottom support unit 2, a lifting unit 3 fixedly connected to the bottom support unit 2 by bolts, a pallet unit 4 arranged on the lifting unit 3, and a module pallet 5 arranged on the pallet unit 4.

[0041] The moving unit 1 is arranged on one side of the bottom support unit 2, and is driven electrically to quickly respond to the instructions of the operator to realize the movement of the entire tooling system; the bottom support unit 2 is used to support the lifting unit 3, the pallet unit 4 and the module pallet 5. During the disassembly process, the bottom support unit 2 provides the necessary support to ensure the overall stability of the tooling system and prevent the tooling from tipping over due to the excessive weight of the disassembled parts. In addition, the part of the bottom of the bottom support unit 2 that contacts the ground also adopts an anti-slip design, which further enhances the safety of the tooling during operation; the lifting unit is used to control the pallet unit 4 to rise and fall, and the pallet unit 4 is moved quickly and smoothly in the vertical direction through the hydraulic drive system, so as to transport the pallet on the pallet unit 4 to the specified height; the pallet unit 4 is used to place the module pallet 5, which is used to place the worn parts after disassembly, and can withstand a large weight and impact force. At the same time, the pallet unit 4 is also provided with a side protection device to ensure that the module pallet 5 can be stably placed on the pallet unit 4 to prevent the module pallet 5 from sliding and falling during transportation. When working in the maintenance warehouse, the disassembly tooling is moved above the trench through the cooperation of the electric transfer vehicle 11 and the forklift pallet slot unit 21, and the tooling is supported as a whole on both sides of the trench by the first support member to disperse the bearing force to the ground, thereby avoiding damage caused by excessive bearing force on the trench.

[0042] Depend on Figure 1 It can be seen that the mobile unit 1 includes an electric transfer vehicle 11 arranged on one side of the bottom support unit. The electric transfer vehicle 11 not only provides efficient movement capability for the disassembly tooling, but also ensures that it can be moved flexibly and accurately in various working environments.

[0043] Specifically, the electric transfer vehicle 11 is a forklift.

[0044] Depend on Figure 2-3 It can be seen that the bottom support unit 2 includes a forklift pallet slot unit 21, a transmission component 22 arranged on the bottom support unit 2, a first support member 24 arranged on both sides of the bottom support unit 2, a first linear guide rail 26, and a mounting plate 23 connected to the slider on the first linear guide rail by bolts; a plurality of track wheels 28 are also provided at the bottom of the bottom support unit 2, and the track wheels 28 are connected to the first support member 24 by bolts;

[0045] Depend on Figure 3 It can be seen that the forklift pallet slot unit 21 includes a first forklift pallet slot 211 longitudinally arranged on the bottom support unit 2 and a second forklift pallet slot 212 transversely arranged on the bottom support unit 2; the forklift pallet slot unit 21 is a slot for the front fork of the electric transfer vehicle, which is convenient for the electric transfer vehicle to easily insert and lift the entire disassembly tooling. The size and shape of the first forklift pallet slot 211 and the second forklift pallet slot 212 are compatible with the front fork of the electric transfer vehicle, and are made of high-strength and wear-resistant materials to ensure that their performance can be maintained during long-term use, thereby extending the service life of the forklift pallet slot unit 21 and improving its carrying capacity.

[0046] It can be foreseen that the first forklift pallet slot 211 and the second forklift pallet slot 212 allow the electric transfer vehicle to be inserted in both the horizontal and longitudinal directions for transfer.

[0047] Depend on Figure 3-4 It can be seen that the transmission component 22 includes a first transmission member 221, a second transmission member 222 and a third transmission member 223; these three members work together to realize the control of the longitudinal direction of the scissor lift platform. The first transmission member 221 is a trapezoidal screw, a screw nut and a commutator. The second transmission member 222 includes a bearing seat, an optical axis and a coupling. The commutator is located on one side of the coupling. The other side of the coupling is provided with a third transmission member 223. The third transmission member 223 includes a shaking handle 2231, a meshing sprocket 2232 and a chain 2233. When the longitudinal position of the scissor lift platform needs to be moved, the user only needs to shake the handle 2231 as needed. Whether it is shaking forward or backward, the power will be transmitted to the second transmission member 222 through the transmission of the sprocket 2232 and the chain 2233, and then transmitted to the first transmission member 221, thereby driving the scissor lift platform 31 above to move longitudinally.

[0048] The mounting plate 23 includes a small mounting plate arranged on one side and a large mounting plate arranged on the opposite side. The mounting plate 23 is a rectangular long plate. The area of ​​the large mounting plate is larger than that of the small mounting plate. The mounting plate is aligned with the edge of the scissors lift and just supports the scissors lift.

[0049] The first support member 24 is fixedly arranged on both sides of the bottom support unit 2. The first support member 24 is a rectangular parallelepiped, and its length is longer than the width of the trench. Therefore, when the electric transport vehicle 11 moves the disassembly tooling to the top of the trench, the first support member 24 can perfectly support the two sides of the trench. When working in the maintenance warehouse, the disassembly tooling is moved to the top of the trench as a whole by matching the size of the front fork of the electric transport vehicle 11 with the forklift pallet slot unit 21, and the disassembly tooling is supported on both sides of the trench by the first support member 24, and then the disassembly operation is performed by adjusting the position of the pallet unit 4.

[0050] Bolt holes are reserved at both ends of the first support member 24 to facilitate the connection between the track wheel 28 and the bottom support unit 2 .

[0051] The first linear guide 26 is fixed on the first support member 24 and is limited by the length of the trapezoidal lead screw, thereby effectively preventing the linear guide from deviating from the track during operation, thereby ensuring the safety of the entire tooling. Optionally, a groove is provided on the first support member 24, and the size and shape of the groove are adapted to the first linear guide 26, so that the first linear guide 26 can be firmly embedded therein, thereby enhancing the connection strength between the guide and the support member.

[0052] A slider is disposed on the first linear guide rail, and the slider is connected to the mounting plate 23 via bolts.

[0053] Depend on Figure 2 It can be seen that the lifting unit 3 includes a scissor lift 31, which connects the bottom support unit 2 below and the pallet unit 4 above. The scissor lift 31 can be raised and lowered in height through its internal hydraulic drive system. The scissor lift 31 is connected to the bottom support unit 2 through the mounting plate 23, and is connected to the pallet unit 4 on the top through bolts. On the pallet unit 4, the parts that need to be repaired can be removed by adjusting the height of the lifting platform, and the parts or equipment that need to be removed can be placed on the module pallet 5.

[0054] Depend on Figure 5-6 It can be seen that the pallet unit 4 includes an upper pallet 41, a lower pallet 42, a second linear guide 44 arranged on the lower pallet 42, a slider 43 arranged between the second linear guide 44 and the upper pallet 41, and a handwheel 45 arranged on one side of the bottom of the pallet unit 4.

[0055] The lower support plate 42 is a rectangular long plate, which is fixedly connected to the lifting platform by bolts. A second linear guide rail 44 is provided on the lower support plate 41, and an upper support plate 41 is provided on the second linear guide rail 44. A slider is provided between the upper support plate and the second linear guide rail 44, and the upper support plate 41 can be moved horizontally by controlling the hand wheel.

[0056] A pallet support 51 is provided below the module pallet 5, and the module pallet 5 is placed on the upper pallet 41. When disassembly work is required, the operator can remove the module pallet 5 from the upper pallet 41, and the removed module pallet 5 can be easily moved to the next work area for repair or replacement, or another prepared module pallet 5 can be placed on the upper pallet 41 to continue the disassembly work. A pallet support 51 is also provided between the module pallet 5 and the upper pallet 41, which enhances the load-bearing capacity of the module pallet 5 and ensures that during the working process, no matter the mass of the carried components, the module pallet 5 can maintain a stable supporting state to avoid damage to the module pallet 5 due to excessive mass of the components.

[0057] Support blocks are also provided on both sides of the bottom of the narrow side of the module pallet 5. The length of the support blocks is consistent with the narrow side of the upper pallet. The narrow side of the upper pallet 41 is provided with a circle of protrusions, namely side protection devices. The support blocks are adapted to the protrusions of the upper pallet 41 to prevent the module pallet 5 from falling during movement.

[0058] The bottom support unit 2 further includes a second support member 25 and a brake component 27 .

[0059] The brake component 27 is provided with a magnetic block 271 inside. When the disassembly tool is used in the temporary repair warehouse, when it reaches the disassembly area and needs to stop, the magnetic block 271 inside the brake component 27 can be attracted to the track bridge, thereby controlling the disassembly tool to stop. The working principle of the magnetic block 271 is that when the tool moves to the position corresponding to the magnetic area on the track bridge, the magnetic block 271 will be attracted by a strong magnetic force, so that it fits tightly with the track bridge, thereby preventing the tool from moving further.

[0060] The second support member 25 is arranged at one side of the second forklift pallet slot, and when the disassembly area is reached, the brake member 27 stops the tooling. The second support member 25 is made of high-strength material, such as Q235A carbon structural steel, to ensure that it has sufficient load-bearing capacity.

[0061] When the disassembling tool is idle, it is supported by contacting the ground through the second support member 25 to prevent the rail wheels from directly contacting the ground and causing wear.

[0062] In one embodiment of the utility model, a scissors lift 31 is provided to achieve lifting in the Z-axis direction, and the support unit 4 achieves movement in the X-axis direction through the cooperation of the second linear guide rail 44 and the slider 43, so that it can move freely in the horizontal direction, thereby achieving lateral positioning of the bottom components of the EMU, and movement in the Y-axis direction is achieved through the cooperation of the bottom support unit 2 and the shaking handle 2231, thereby achieving longitudinal positioning of the bottom components of the EMU, accurately positioning the bottom components of the vehicle, facilitating disassembly and installation, and improving work efficiency.

[0063] Example 2

[0064] The other components of this embodiment are the same as those of the embodiment 1, except that the bottom support unit 2 of this embodiment further includes a track wheel 28 .

[0065] The track wheel 28 is arranged at the bottom of the bottom support unit 2, and there are four track wheels. When the tooling is operating in the temporary repair warehouse, it can be connected to the bottom of the bottom support unit 2 by bolts. In actual operation, when the tooling needs to be disassembled for operation in the temporary repair warehouse, the operator only needs to connect the track wheel 28 to the bottom of the bottom support unit 2 by bolts and transport it to the track bridge through the electric transfer vehicle 11. The disassembly tooling can be moved on the track bridge as a whole. Through the rolling of the track wheel 28, the disassembly tooling can be quickly and smoothly moved to the bottom of the vehicle bottom component that needs to be disassembled. After reaching the designated position, the operator can perform the disassembly operation.

[0066] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
