Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0042] The core of this utility model is to provide a vehicle transfer platform, which has a simple structure, small size, and light weight. Another core aspect of this utility model is to provide a vehicle transfer platform system including the above-mentioned vehicle transfer platform, wherein the vehicle transfer platform has a simple structure, small size, and light weight.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a vehicle transfer platform for transferring rail vehicles. The vehicle transfer platform includes a support platform 1 and a linear motor 2. The upper part of the support platform 1 is used to set up the vehicle. The linear motor 2 is set at the bottom of the support platform 1. The linear motor 2 is used to cooperate with the induction plate 7 set on the fixed base surface 6 to generate traction force to drive the support platform 1 to move.

[0044] It is understandable that the induction plate 7 is set in the line of the linear motor 2 that moves together with the moving platform on the fixed base 6. When the linear motor 2 is powered on, it can generate a moving magnetic field with the induction plate 7, and generate traction force through the interaction between the magnetic forces.

[0045] In other words, the vehicle transfer platform provided in this embodiment of the present invention improves the power device of the vehicle transfer platform in the related technology. The vehicle transfer platform in this embodiment of the present invention adopts a linear motor 2, which works in conjunction with the induction plate 7 set on the fixed base surface 6 to generate traction force on the support platform 1, thereby driving the support platform 1 to move, so as to realize the transportation work of the vehicle transfer platform for rail vehicles.

[0046] Compared to related technologies, this vehicle transfer platform uses a linear motor 2 directly driven by an induction plate 7 on a fixed base surface 6, eliminating the need for a complex transmission system. This simplifies the platform's mechanical structure, reducing its size and weight, thus facilitating miniaturization and weight reduction. Furthermore, the elimination of the transmission system significantly reduces frictional losses between mechanical transmission components, extending maintenance cycles, lowering maintenance frequency, and reducing maintenance difficulty and costs. Additionally, it is compatible with existing fixed base surfaces 6 (such as existing foundations), requiring only the installation of an induction plate 7 on the existing base surface 6, making it highly scalable.

[0047] It should be noted that the linear motor 2 can be divided into linear asynchronous motors and linear synchronous motors according to its operating mode. This embodiment does not limit the specific type of linear motor 2. For example, the linear motor 2 can be a linear asynchronous motor or a linear synchronous motor. The linear asynchronous motor has low cost, the speed of the linear motor 2 can be controlled by a frequency converter, and it is generally used as a short stator linear motor 2, with the induction plate 7 used as the rotor.

[0048] In addition, because the working gap between the linear motor 2 and the sensing plate 7 is small, in order to prevent foreign objects from entering the gap between the linear motor 2 and the sensing plate 7 and causing damage to the linear motor 2 and / or the sensing plate 7, such as... Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, along the moving direction of the car transfer platform, the two ends of the linear motor 2 are respectively provided with obstacle removers 3, which are used to remove foreign objects on the fixed base surface 6.

[0049] In other words, this embodiment uses the obstacle remover 3 to remove foreign objects from the line of the linear motor 2 corresponding to the fixed base surface 6 during the movement of the vehicle transfer platform, thereby preventing foreign objects from entering between the linear motor 2 and the sensing plate 7, thus ensuring the reliability of the linear motor 2 and the sensing plate 7, and ensuring the reliable operation of the vehicle transfer platform.

[0050] It should be noted that the specific structure of the obstacle remover 3 is not limited in this embodiment, as long as the obstacle remover 3 can remove foreign objects on the fixed base surface 6 and prevent foreign objects from entering between the linear motor 2 and the sensing plate 7.

[0051] For example, in some embodiments, the obstacle remover 3 includes a scraper, the bottom surface of which protrudes from the bottom surface of the linear motor 2; the width of the scraper is greater than or equal to the width of the linear motor 2 along the moving direction perpendicular to the moving platform.

[0052] In other words, the bottom of the scraper must be lower than the bottom of the linear motor 2, and the gap between the scraper and the fixed base 6 must be zero or less than the gap between the linear motor 2 and the sensing plate 7. This facilitates the removal of foreign objects from the fixed base 6 and prevents foreign objects from entering between the linear motor 2 and the sensing plate 7. Along the moving direction perpendicular to the transfer platform, the width of the scraper is greater than or equal to the width of the linear motor 2, which helps improve the reliability of the scraper and makes it easier to ensure that foreign objects do not enter between the linear motor 2 and the sensing plate 7.

[0053] It should be noted that this embodiment does not limit the specific structure and material of the scraping component. For example, the scraping component can be a brush or a scraping plate.

[0054] In addition, this embodiment does not limit the specific configuration of the obstacle remover 3. For example, the obstacle remover 3 also includes a fixing plate connected to the scraping component, and the fixing plate is fixed to the end of the linear motor 2 by fasteners.

[0055] In addition, considering the braking method of the transfer platform, such as Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the support platform 1 is provided with at least three running wheel devices 4, and at least two running wheel devices 4 are provided with electromagnetic braking devices 5, which are used to brake the running wheel devices 4.

[0056] Understandably, the traveling wheel device 4 is used for support and movement. Under the traction force generated by the interaction between the linear motor 2 and the induction plate 7, the traveling wheel device 4 moves along the fixed base surface 6. The number of traveling wheel devices 4 is three or more to ensure the stability of the plane on which the transfer platform is located. For example, the number of traveling wheel devices 4 can be four, six, or other numbers.

[0057] Furthermore, in this embodiment, an electromagnetic braking device 5 is used to brake the traveling wheel assembly 4. Two or more traveling wheel assemblies 4 can be selected to install the electromagnetic braking device 5 to achieve braking of the entire transfer platform. Using the electromagnetic braking device 5 to control the application and release of braking results in a faster braking response.

[0058] Considering the specific structure of the electromagnetic braking device 5, such as Figure 6 As shown, in some embodiments, the electromagnetic braking device 5 includes a friction plate 51, a brake pad 52, an elastic element 53, and a magnetic circuit device. The friction plate 51 is connected to the axle 42 of the running wheel device 4; the brake pad 52 is connected to the axle box 41 of the running wheel device 4 through the elastic element 53; the magnetic circuit device is located in the axle box 41 and is used to generate magnetic attraction force on the brake pad 52 or release the brake pad 52.

[0059] In other words, this embodiment uses the energization and de-energization of the magnetic circuit device to control the application and release of the car transfer platform's braking. For example, when the car transfer platform moves, the magnetic circuit device generates a magnetic attraction force on the brake pad 52, causing the brake pad 52 to move away from the friction plate 51. There is a certain gap between the brake pad 52 and the friction plate 51, thereby ensuring the smooth movement of the car transfer platform. It can be understood that when the brake pad 52 moves away from the friction plate 51, the brake pad 52 squeezes the elastic element 53, causing the elastic element 53 to store elastic force. When braking is required, the magnetic circuit device is de-energized, and under the action of the elastic force of the elastic element 53, the brake pad 52 is pushed to come into contact with the friction plate 51, so that the brake pad 52 and the friction plate 51 rub against each other to brake. The friction plate 51 is located on the axle 42 of the running wheel device 4, that is, the braking force of the electromagnetic braking device 5 is directly applied to the side of the axle 42 of the running wheel device 4, which is beneficial to make the braking response faster.

[0060] It should be noted that this embodiment does not limit the specific structure and quantity of the elastic element 53. For example, the elastic element 53 can be a spring, and the quantity of the elastic element 53 can be at least one.

[0061] In addition, the above embodiments do not limit the specific structure of the traveling wheel device 4, as long as it can enable the traveling wheel device 4 to travel on the fixed base surface 6.

[0062] like Figure 5 As shown, in some embodiments, the running wheel device 4 includes an axle box 41, an axle 42, a wheel 44 and a baffle 45. The axle box 41 is connected to the support platform 1; the axle 42 is connected to the axle box 41 through a bearing 43; the wheel 44 is connected to the axle 42; the baffle 45 is connected to the axle box 41 and covers the upper part of the wheel 44.

[0063] In other words, in this embodiment, the running wheel device 4 is mounted on the support platform 1 via the axle box 41, and the axle box 41 provides rotational support for the axle 42, thereby enabling the wheel 44 to travel on the fixed base surface 6. In addition, the baffle 45 is provided to protect the wheel 44.

[0064] In addition, to facilitate the installation of vehicles on the support platform 1, such as Figure 1 and Figure 3 As shown, in some embodiments, the support platform 1 is provided with a first track 11, which includes a wide track 111, a standard track 112 and a narrow track 113.

[0065] In other words, when the vehicle is placed on the support platform 1, the vehicle is positioned on the corresponding first track 11, which includes a wide track 111, a standard track 112, and a narrow track 113 to improve the applicability of the vehicle.

[0066] In addition, such as Figure 3As shown, in some embodiments, walking platforms 12 are respectively provided on both sides of the top of the support platform 1.

[0067] In other words, this embodiment provides a walking platform 12 on both sides of the top of the support platform 1, so as to facilitate the movement of operators during the production and manufacturing process.

[0068] In addition to the aforementioned vehicle relocation platform, this utility model also provides a vehicle relocation platform system including the vehicle relocation platform disclosed in the above embodiments. The vehicle relocation platform system further includes a fixed base surface 6, which is provided with a sensing plate 7. The sensing plate 7 is used to cooperate with the linear motor 2 of the vehicle relocation platform to generate traction force to drive the carrier platform 1 of the vehicle relocation platform to move.

[0069] In other words, the focus of this embodiment is to use the transfer platform disclosed in any of the above embodiments, and to set the induction plate 7 on the fixed base surface 6. The linear motor 2 at the bottom of the transfer platform works in conjunction with the induction plate 7 to generate traction force on the transfer platform to drive the transfer platform to move. This includes at least the beneficial effects of the transfer platform mentioned above, which will not be repeated here.

[0070] In addition, in some embodiments, the fixed base surface 6 is provided with a second track 61, which is used to limit the movement of the transfer platform.

[0071] In other words, this embodiment uses a second track 61 set on the fixed base surface 6 to guide and limit the movement of the transfer platform, thereby ensuring the correctness of the movement direction and the stability of the movement.

[0072] Understandably, the second track 61 is used to guide and limit the traveling wheel device 4 of the transfer platform. The number of second tracks 61 is the same as the number of traveling wheel devices 4, and the second tracks 61 are set corresponding to the traveling wheel devices 4.

[0073] It should also be noted that, in this specification, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0074] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0075] The foregoing has provided a detailed description of the vehicle transfer platform and system provided by this utility model.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model.
