Description

Technical Field

[0001] This application belongs to the field of bogie transfer technology, specifically relating to a transfer vehicle. Background Technology

[0002] Automated Guided Vehicles (AGVs) are a type of mobile robot and an important piece of equipment in the logistics systems of modern manufacturing enterprises. They are mainly used for storing and transporting various materials, providing an important guarantee for the flexibility, integration, and efficient operation of the system. They are usually powered by batteries and equipped with non-contact guidance devices. With the assistance of computer control and guidance devices, they can accurately reach their destination.

[0003] Existing AGV vehicles for pushing items, such as those used in rail transit for pushing track equipment (e.g., bogies), typically employ a pushing clamp that moves laterally along the width of the vehicle to hold the wheel surfaces of the bogie. The pushing clamp has rollers on both sides along the width of the vehicle, two on each side. The two rollers on the same side roll into contact with the treads of the front and rear wheels respectively, or the two rollers on the same side roll into contact with the front and rear treads of the same wheel. This type of pushing clamp is only suitable for one type of bogie and lacks versatility. Summary of the Invention

[0004] To address the technical problem of low versatility of current transfer vehicles, this application provides a transfer vehicle.

[0005] This application provides a transfer vehicle for transferring bogies, the transfer vehicle comprising:

[0006] Vehicle body;

[0007] The transverse movement mechanism is provided in multiple ways and is arranged sequentially along the length direction of the vehicle body. The transverse movement mechanism includes a first driving member and two transverse movement members. The first driving member is installed on the vehicle body and is connected to the two transverse movement members in a transmission manner. It drives the two transverse movement members to move towards each other or away from each other in the width direction of the vehicle body. The output parts of the two transverse movement members are located outside the vehicle body.

[0008] The longitudinal movement mechanism has the same number as the lateral movement component and corresponds one-to-one with the lateral movement component. The longitudinal movement mechanism includes a second driving component, a longitudinal movement component, and a roller. The second driving component is installed on the output part of the lateral movement component, and the roller is rotatably installed on the longitudinal movement component. The second driving component drives the longitudinal movement component to move back and forth along the length direction of the vehicle body so that the roller acts on the wheel tread of the bogie.

[0009] In some embodiments, the first driving member is a linear driving mechanism, the telescopic end of which is connected to one of the two lateral moving members. The lateral moving mechanism also includes a gear rotatably mounted on the vehicle body. Both lateral moving members are provided with racks, and the two lateral moving members are respectively located on both sides of the gear in the length direction of the vehicle body, such that the racks on both lateral moving members mesh with the gear.

[0010] In some embodiments, the lateral movement mechanism further includes a first guide rail that is the same number as and corresponds one-to-one with the lateral movement members. The first guide rail is disposed on the vehicle body along the width direction of the vehicle body, and the lateral movement member slides in cooperation with the corresponding first guide rail.

[0011] In some embodiments, two lateral movement mechanisms are provided, located along the length of the vehicle body between two wheel axles of the bogie.

[0012] In some embodiments, the lateral movement member includes a sliding portion and the output portion connected together, the sliding portion being slidably connected to the vehicle body;

[0013] Along the length of the vehicle body, the size of the output section is larger than that of the sliding section.

[0014] In some embodiments, in the two lateral members of the same lateral mechanism, the projection of the sliding part falls within the projection of the output part along the width direction of the vehicle body.

[0015] In some embodiments, in the two traversing members of the same traversing mechanism, along the length direction of the vehicle body, the output portion of one traversing member at least partially overlaps with the sliding portion of the other traversing member; and / or,

[0016] Along the width direction of the vehicle body, the output portion of one of the lateral movement members and the sliding portion of the other lateral movement member are spaced apart.

[0017] In some embodiments, the lateral movement mechanism is symmetrically arranged in the width direction of the vehicle body.

[0018] In some embodiments, the lateral movement mechanism is mounted on the underside of the vehicle body.

[0019] In some embodiments, the second driving member is a rotary driving mechanism, and the longitudinal moving mechanism further includes a lead screw and a second guide rail. The rotary driving mechanism is drivenly connected to the lead screw, the second guide rail is installed on the output part, the longitudinal moving member is threadedly connected to the lead screw and slidably engaged with the second guide rail, and the roller is rotatably installed on the longitudinal moving member.

[0020] The transfer vehicle provided according to the embodiments of this application includes a vehicle body, a transverse movement mechanism, and a longitudinal movement mechanism. Multiple transverse movement mechanisms are provided and arranged sequentially along the length direction of the vehicle body. The transverse movement mechanism includes a first driving member and two transverse movement members, and one first driving member is simultaneously connected to two transverse movement members for transmission, thereby realizing the extension of two longitudinal movement mechanisms. The rollers of the longitudinal movement mechanism can reciprocate along the length direction of the vehicle body, thereby rolling and cooperating with wheel treads of different diameters, improving the application range and versatility.

[0021] The lateral movement mechanism uses only one first drive component to achieve lateral movement of the two longitudinal movement mechanisms. This reduces the number of parts, lowers cost, and makes maintenance easier. Because the car body is relatively wide, although the bogies have different specifications, the wheel size variation is relatively small compared to the car body width. Therefore, the longitudinal travel of the rollers in the longitudinal movement mechanism is smaller than the lateral travel of the lateral movement component. Consequently, the longitudinal dimension of the longitudinal movement mechanism is smaller than the lateral dimension of the lateral movement mechanism. The smaller longitudinal movement mechanism is installed at the output end of the larger lateral movement component, which improves the rigidity of both the lateral and longitudinal movement mechanisms, resulting in better stability during operation.

[0022] In addition, the longitudinal and transverse mechanisms are almost in the same horizontal space, and they hardly leave this horizontal space during the operation process, so they occupy less space and have a more compact structure. Attached Figure Description

[0030] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] The bogie is a crucial component of rail vehicles, primarily used to support the car body, mount wheels, transmit traction and braking forces, and enable vehicle steering. A bogie consists of a frame and wheelsets. Each wheelset includes an axle and two wheels mounted at each end of the axle. Two wheelsets are typically arranged sequentially along the length of the frame. Bogies are generally moved using an automated guided vehicle (AGV). Bogie wheels come in various sizes; for example, common railway passenger car wheels have a diameter of approximately 915 mm, while high-speed train wheels have a relatively larger diameter, generally around 920 mm, and mining transport vehicle wheels may have a diameter of around 840 mm. Furthermore, after a period of operation, the wheel tread (the circumferential surface of the wheel in contact with the rail) wears down due to friction with the rail, gradually reducing its diameter.

[0032] In related technologies, the pusher fixture has rollers on both sides along the width of the vehicle, with two on each side. The two rollers on the same side roll with the treads of the front and rear wheels respectively, or the two rollers on the same side roll with the front and rear treads of the same wheel. Once the diameter of the bogie wheel changes, it means that the distance between the two rollers on the same side needs to be adjusted. At this time, it is necessary to replace the transfer vehicle with one that conforms to the diameter of the target bogie. Therefore, the versatility of this pusher fixture is not strong.

[0033] This application provides a transfer vehicle capable of transferring bogies, wherein the rollers can move both laterally and longitudinally, making it suitable for bogies with different wheel diameters, highly versatile, with few parts and low cost.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Please see Figure 1 as well as Figure 2The transfer vehicle provided in this application embodiment includes a vehicle body 100, a transverse movement mechanism 200, and a longitudinal movement mechanism 300. Multiple transverse movement mechanisms 200 are provided, arranged sequentially along the length direction of the vehicle body 100. Each transverse movement mechanism 200 includes a first driving member 210 and two transverse movement members 220. The first driving member 210 is mounted on the vehicle body 100 and is connected to the two transverse movement members 220 in a transmission manner, driving the two transverse movement members 220 to move towards or away from each other in the width direction of the vehicle body 100. The output portions 222 of the two transverse movement members 220 are located outside the vehicle body 100. The longitudinal movement mechanism 300 has the same number as the transverse movement member 220 and corresponds one-to-one with the transverse movement member 220. The longitudinal movement mechanism 300 includes a second drive member 310, a longitudinal movement member 340 and a roller 350. The second drive member 310 is installed on the output part 222 of the transverse movement member 220, and the roller 350 is rotatably installed on the longitudinal movement member 340. The second drive member 310 drives the longitudinal movement member 340 to move back and forth along the length direction of the vehicle body 100 so that the roller 350 acts on the tread of the wheel 402 of the bogie 400.

[0036] The car body 100 is the main structure of the transfer car. It is equipped with traveling wheels 101 and a power mechanism that drives the traveling wheels 101 to move, thereby enabling the car body 100 to move and thus driving the bogie 400 to move.

[0037] Generally, the bogie 400 has two pairs of wheelsets, namely two axles 401 and four wheels 402. Multiple lateral movement mechanisms 200 are provided, such as two, three, or four. With two lateral movement mechanisms 200, the rollers 350 can be used to abut the front and rear wheels 402 respectively (see...). Figure 3 Alternatively, the first drive member 210 can be fixed to the front and rear positions of the same wheel 402. It is connected to the two lateral movement members 220, allowing them to move relative to or away from each other along the width direction of the vehicle body 100. The longitudinal movement mechanism 300 is installed at the output section 222 of the lateral movement members 220, enabling it to reciprocate along the width direction of the vehicle body 100. The second drive member 310 of the longitudinal movement mechanism 300 can drive the longitudinal movement member 340 to move along the length direction of the vehicle body 100, thereby causing the roller 350 to move back and forth. Therefore, the roller 350 can move closer to or further away from the tread of the wheel 402.

[0038] Therefore, under the combined action of the lateral movement mechanism 200 and the longitudinal movement mechanism 300, the roller 350 can achieve position adjustment in both the width and length directions of the car body 100, thus switching back and forth between the waiting position and the working position. When the bogie 400 is not needed for transfer, the roller 350 is in the waiting position, located between two wheels 402 on the same axle 401 along the width direction of the car body 100. When the bogie 400 needs to be transferred, the roller 350 switches to the working position under the action of the lateral movement mechanism 200 and the longitudinal movement mechanism 300. At this time, the roller 350 rolls with the tread of the corresponding wheel 402, and the transfer frame moves during the movement of the car body 100. The lateral and longitudinal position adjustment of the roller 350 can adapt to bogies with wheels of various diameters. When the wheel diameter of the bogie changes, only the longitudinal amount of the roller 350 needs to be adjusted, which is highly versatile. The roller 350 has a high degree of contact with the wheel tread, making the transfer process more stable.

[0039] For ease of explanation, the two transverse components 220 of the transverse mechanism 200 are named the first transverse component 220a and the second transverse component 220b, respectively.

[0040] The lateral movement mechanism 200 serves as the structure for achieving lateral adjustment of the roller 350. In some embodiments, the first drive member 210 is a linear drive mechanism, such as an electric cylinder, a pneumatic cylinder, or a ball screw mechanism. Please refer to [link to relevant documentation]. Figure 2 The lateral movement mechanism 200 includes a gear 230 rotatably mounted on the vehicle body 100. The first lateral movement member 220a and the second lateral movement member 220b are both provided with racks 223. The first lateral movement member 220a and the second lateral movement member are respectively located on both sides of the gear 230 in the length direction of the vehicle body 100, and the racks 223 of the first lateral movement member 220a and the second lateral movement member are both meshed with the gear 230. The telescopic end of the linear drive mechanism is connected to the first lateral movement member 220a.

[0041] The telescopic end of the linear drive mechanism can drive the first lateral moving member 220a to move along the width direction of the vehicle body 100, thereby driving the longitudinal moving mechanism 300 mounted on the first lateral moving member 220a to adjust laterally. The rack 223 of the first lateral moving member 220a meshes with the gear 230, so during the lateral movement of the first lateral moving member 220a, it will drive the gear 230 to rotate. The rack 223 of the second lateral moving member 220b also meshes with the gear 230, so the second lateral moving member 220b will also move laterally under the drive of the gear 230, thereby driving the longitudinal moving mechanism 300 mounted on the second lateral moving member 220b to adjust laterally. In this way, one first drive member 210 realizes the lateral position adjustment of two lateral moving members 220.

[0042] In other embodiments, the transverse mechanism 200 may also include a rotary motor and a threaded rod. The rotary motor is connected to the threaded rod in a transmission manner, thereby driving the threaded rod to rotate. The threaded rod has two threaded sections with opposite thread directions. The transverse member 220 is threadedly connected to the two threaded sections respectively, thereby enabling the first transverse member 220a and the second transverse member 220b to move closer or further apart.

[0043] Please see Figure 1 as well as Figure 2 The lateral movement mechanism 200 may further include two first guide rails 240, each corresponding to a first lateral movement member 220a and a second lateral movement member 220b. The first guide rails 240 are positioned along the width direction of the vehicle body 100, and the first lateral movement member 220a and the second lateral movement member 220b are slidably engaged with their respective first guide rails 240. Both first guide rails 240 extend along the width direction of the vehicle body 100 and slidably engage with the first lateral movement member 220a and the second lateral movement member 220b, thereby improving the stability of the first lateral movement member 220a and the second lateral movement member 220b during lateral position adjustment. The engagement method between the first guide rails 240 and the lateral movement member 220 can be determined as needed. For example, the lateral movement member 220 may have a groove extending along the width direction of the vehicle body 100, and the first guide rail 240 may engage within the groove. For example, both the first transverse member 220a and the second transverse member 220b are provided with sliding protrusions extending along the width direction of the vehicle body 100, and the first guide rail 240 is provided with a sliding groove, with the sliding protrusions slidingly engaged in the corresponding sliding grooves.

[0044] In some embodiments, two lateral movement mechanisms 200 may be provided, located along the length of the vehicle body 100, between the two wheel axles 401 of the bogie 400. This ensures the stability of the bogie 400 during transport and also saves costs.

[0045] Please see Figure 1 as well as Figure 2Both the first lateral moving member 220a and the second lateral moving member 220b may include a sliding part 221 and an output part 222 connected to each other. The sliding part 221 is slidably connected to the vehicle body 100. Specifically, the sliding part 221 is slidably connected to the corresponding first guide rail 240, and the rack 223 is located in the sliding part 221. Along the length direction of the vehicle body 100, the size of the output part 222 is larger than that of the sliding part 221. That is, the size of the output part 222 along the length direction of the vehicle body 100 is larger, and the size of the sliding part 221 along the length direction of the vehicle body 100 is smaller. The larger size of the output part 222 can provide sufficient space for the arrangement of the longitudinal moving mechanism 300 and improve the connection strength between the output part 222 and the longitudinal moving mechanism 300. The smaller size of the sliding part 221 can reduce the space occupied, and the lateral moving mechanism 200 can be reasonably arranged, resulting in a more compact structure. In other embodiments, the size of the output part 222 is smaller than or equal to the size of the sliding part 221 along the length direction of the vehicle body 100, and the installation of the longitudinal movement mechanism 300 can still be achieved.

[0046] In some embodiments, in the first lateral movement member 220a and the second lateral movement member 220b of the same lateral movement mechanism 200, along the width direction of the vehicle body 100, the projection of the sliding portion 221 of the first lateral movement member 220a falls within the projection of the output portion 222, and the projection of the sliding portion 221 of the second lateral movement member 220b also falls within the projection of the output portion 222. That is, along the width direction of the vehicle body 100, one or both sides of the output portion 222 protrude from the sliding portion 221, so as to achieve a structure in which the output portion 222 is large and the sliding portion 221 is small along the length direction of the vehicle body 100. In some embodiments, one side of the output portion 222 along the width direction of the vehicle body 100 is flush with the sliding portion 221, and the other side protrudes from the sliding portion 221. That is, both the first lateral movement member 220a and the second lateral movement member 220b are set to L-shape, which facilitates processing.

[0047] In some embodiments, the output portion 222 and the sliding portion 221 can be an integral structure, which can be obtained by machining. In other embodiments, the output portion 222 and the sliding portion 221 can also be separate structures, which are connected by welding or screwing.

[0048] Please see Figure 1 as well as Figure 2In the same lateral movement mechanism 200, in the first lateral movement member 220a and the second lateral movement member 220b, along the length direction of the vehicle body 100, the output portion 222 of the first lateral movement member 220a and the sliding portion 221 of the second lateral movement member 220b at least partially overlap; and / or, the sliding portion 221 of the first lateral movement member 220a and the output portion 222 of the second lateral movement member 220b at least partially overlap. This arrangement can reduce the size of the lateral movement mechanism 200 along the length direction of the vehicle body 100, making the structure more compact and improving space utilization. In other embodiments, the first lateral movement member 220a and the second lateral movement member 220b can also be arranged sequentially along the length direction of the vehicle body 100, still achieving the lateral movement of two lateral movement members 220 with one first drive member 210.

[0049] In some embodiments, please refer to Figure 1 as well as Figure 2 In the same lateral movement mechanism 200, in the first lateral movement member 220a and the second lateral movement member 220b, along the width direction of the vehicle body 100, the output portion 222 of the first lateral movement member 220a and the sliding portion 221 of the second lateral movement member 220b are spaced apart, and the sliding portion 221 of the first lateral movement member 220a and the output portion 222 of the second lateral movement member 220b are also spaced apart. This arrangement ensures that the first lateral movement member 220a and the second lateral movement member 220b do not interfere with each other, and the lateral movement adjustment of the roller 350 is smooth.

[0050] In some embodiments, the lateral movement mechanism 200 is symmetrically arranged in the width direction of the vehicle body 100, which ensures that the rollers 350 are also symmetrically arranged, and can simultaneously and precisely roll and cooperate with the treads of the two wheels 402 on the same axle 401.

[0051] In some embodiments, the lateral movement mechanism 200 can be disposed on the lower surface of the vehicle body 100, which can prevent dust and prevent contamination. In other embodiments, the lateral movement mechanism 200 can also be disposed on the upper surface of the vehicle body 100, while still achieving the installation of the lateral movement mechanism 200.

[0052] The longitudinal movement mechanism 300 serves as a structure for longitudinal adjustment of the roller 350, and the longitudinal movement member 340 can be a longitudinal movement block or a longitudinal movement frame. In some embodiments, the second drive member 310 can be a rotary drive mechanism or a linear drive mechanism. When the second drive member 310 is a rotary drive mechanism, such as a rotary motor, please refer to [reference needed]. Figure 1 as well as Figure 2 The longitudinal movement mechanism 300 also includes a lead screw 320 and a second guide rail 330. The rotary drive mechanism is connected to the lead screw 320. The second guide rail 330 is installed on the output part 222 and is arranged along the length direction of the vehicle body 100. The longitudinal movement member 340 is threadedly connected to the lead screw 320 and slides with the second guide rail 330. The roller 350 is rotatably installed on the longitudinal movement member 340.

[0053] A rotary drive mechanism is installed on the output section 222, which has a rotatable output end. The rotatable output end is connected to the lead screw drive, thereby driving the lead screw to rotate. Since the lead screw is threadedly connected to the longitudinal moving member 340, and the longitudinal moving member 340 is slidably engaged with the second guide rail 330 installed on the output section 222, the longitudinal moving member 340 can move along the extension direction of the second guide rail 330 during the rotation of the lead screw, thereby driving the roller 350 to adjust its longitudinal position.

[0054] In other embodiments, the second drive member 310 can also be a telescopic member such as a cylinder or an electric cylinder. The fixed end of the telescopic member is installed on the output part 222, and the telescopic end is connected to the longitudinal movement member 340, which can also realize the longitudinal position adjustment of the roller 350.

[0055] The transfer vehicle provided in this application has at least the following advantages:

[0056] (1) The transfer car is equipped with a transverse movement mechanism 200 and a longitudinal movement mechanism 300, which makes the transverse and longitudinal positions of the roller 350 adjustable. This allows the distance between the front and rear rollers 350 to be adjusted, thus making it suitable for bogies with different wheel diameters and more versatile.

[0057] (2) The transverse mechanism 200 is equipped with only one first drive component 210 to realize the transverse movement of the two longitudinal mechanisms 300. The number of parts is small, the cost is low, and the maintenance is more convenient.

[0058] (3) Since the width of the car body 100 is relatively wide, although the bogie 400 has different specifications, the diameter of the wheel 402 is still relatively small compared to the width of the car body 100. Therefore, the longitudinal travel of the roller 350 in the longitudinal movement mechanism 300 is smaller than the lateral travel of the transverse movement component 220. Thus, the longitudinal dimension of the longitudinal movement mechanism 300 is smaller than the lateral dimension of the transverse movement mechanism 200. The smaller longitudinal movement mechanism 300 is installed at the output end of the larger transverse movement component 220, which can improve the rigidity of the transverse movement mechanism 200 and the longitudinal movement mechanism 300, and the stability during use is better.

[0059] (4) The longitudinal movement mechanism 300 and the transverse movement mechanism 200 are almost in the same horizontal space, and they hardly leave this horizontal space during the operation process. Therefore, they occupy less space and have a more compact structure.

[0060] (5) Both the first transverse component 220a and the second transverse component 220b are set to L-shape, which not only meets the installation space requirements of the longitudinal mechanism 300, but also saves space and has a compact structure.
