Description

Technical Field

[0001] This application relates to the technical field of goods handling equipment, and more particularly to a rail-guided vehicle. Background Technology

[0002] In modern warehousing and logistics systems and automated production lines, the efficient and accurate transport of materials from their initial location to their destination is crucial for ensuring the smooth operation of the overall workflow. With the continuous expansion of industrial scale and rising labor costs, traditional methods relying on manual handling are no longer sufficient to meet the demands of high-efficiency, high-intensity production and logistics. Therefore, using rail-guided trolleys for material transport has become an effective solution. These devices can automatically run along pre-set tracks, significantly reducing the burden of manual handling, improving material flow efficiency, lowering operating costs, and facilitating the intelligent and automated management of the entire logistics system.

[0003] Commonly used rail-guided trolleys typically consist of a chassis structure with supports or platforms mounted on it to carry materials. Below the chassis are wheel assemblies that match the tracks. Driven by a motor, these wheels travel along the tracks laid on the ground, propelling the entire trolley along a set path to complete the fixed-point material transport task. This type of equipment is simple in structure, stable in operation, and suitable for fixed-route material transport within factories or between warehouses, and has been widely used in various industries.

[0004] However, existing track-guided vehicles still have certain technical shortcomings, especially in handling non-straight paths. Most current guided vehicles can only adapt well to straight tracks, limiting their application in complex paths requiring curves. When a guided vehicle carrying a heavy load passes through a curve, inertia generates a significant lateral force in its original direction of travel. This places higher demands on the coordination between the turning wheels and the track. Existing wheel structures often cannot adjust their direction of travel in advance according to the track's trajectory, leading to a high risk of derailment during turns due to the vehicle's inertia, thus affecting the safety and stability of the equipment. Therefore, improving the steering structure of track-guided vehicles to adapt to curved paths and effectively reduce the probability of derailment has become an important research direction for enhancing their application range and technical performance. Utility Model Content

[0005] This application provides a track-guided vehicle that solves the technical problem that existing track-guided vehicles cannot perform turning operations in advance based on the direction of travel on non-linear tracks. The technical solution is as follows:

[0006] This application provides a track-guided vehicle, including: a chassis; a support frame disposed above the chassis for carrying materials; four slewing bearings disposed in pairs at the bottom of the chassis; four wheel assemblies rotatably mounted on the chassis via corresponding slewing bearings for cooperating with tracks configured on the site; and four guide wheels rotatably mounted on the chassis via corresponding slewing bearing shafts, each guide wheel being disposed on the outside of the corresponding wheel assembly along the running direction for guiding the corresponding wheel assembly to run on a curved track.

[0007] Each wheel assembly and each guide wheel are steered on the chassis via corresponding slewing bearings.

[0008] In one embodiment, each set of two slewing bearings is arranged side by side at the bottom of the chassis; the slewing bearing includes: a fixed member, mounted on the bottom of the chassis; a rotating member, rotatably sleeved on the fixed member; a base plate, connected to the rotating member and rotating synchronously with the rotating member; and each wheel assembly and each guide wheel are disposed on the corresponding base plate.

[0009] In one embodiment, the wheel assembly includes: a bearing housing mounted on the side of the base plate opposite to the rotating component; a first bearing component, with a shaft seat sleeved at both ends of the first bearing component; and a wheel rotatably mounted on the bearing housing via the first bearing component. The outer edge of the radial side of the wheel has a first fitting portion and a first limiting portion, the diameter of the first fitting portion being smaller than the diameter of the first limiting portion. The first fitting portion is used to contact the upper surface of the track, and the first limiting portion is used to fit against one side of the track.

[0010] In one embodiment, the wheel assembly further includes: two hinged posts mounted on the surface of the base plate rotating member, the ends of the two hinged posts opposite to the base plate being hinged to the bearing housing and located on the side of the bearing housing close to the guide wheel; and two elastic elements mounted on the surface of the base plate rotating member, the two elastic elements being elastically supported between the base plate and the bearing housing and located on the side of the bearing housing opposite to the guide wheel.

[0011] In one embodiment, it further includes: four adjustable mounting seats, each guide wheel being configured on the base plate via a corresponding adjustable mounting seat;

[0012] The adjusting mounting base includes: a sliding sleeve, mounted on the surface of the base plate opposite to the rotating part, the sliding sleeve having an adjusting hole, and a through hole that mates with the adjusting hole being provided on the base plate; a sliding column, slidably mounted in the adjusting hole, one end of the sliding column having a limiting block with a diameter larger than the adjusting hole, and the other end of the sliding column being provided with a mounting lug; and a second bearing component, disposed on the mounting lug, through which the guide wheel is rotatably mounted on the mounting lug.

[0013] In one embodiment, the outer edge of the radial side of the guide wheel has a second fitting portion and a second limiting portion. The diameter of the second fitting portion is smaller than the diameter of the second limiting portion. The second fitting portion is used to contact the upper surface of the track, and the second limiting portion is used to fit against one side of the track.

[0014] In one embodiment, it further includes: a linkage component connected between each group of two slewing bearings, wherein the two slewing bearings rotate synchronously through the linkage component.

[0015] In one embodiment, the linkage assembly includes: four joint components, each hingedly disposed on the base plate of four slewing bearings; and two connecting rods, each connected to two joint components on a set of two slewing bearings, so that the two slewing bearing shafts rotate synchronously through the cooperation of the two joint components and the corresponding connecting rods.

[0016] In one embodiment, it further includes two drive mechanisms disposed on two of the wheel assemblies for driving the wheels in the corresponding wheel assemblies to rotate.

[0017] In one embodiment, the drive mechanism includes: a speed reduction transmission assembly mounted on one side of a corresponding bearing housing, the speed reduction transmission assembly having an output end and an input end, the output end being synchronously rotatably connected to a corresponding first bearing component; and a drive motor mounted on the speed reduction transmission assembly, the output shaft of the drive motor being synchronously rotatably connected to the input end, so as to apply the rotational force of the output shaft to the first bearing component after being reduced by the speed reduction transmission assembly.

[0018] Compared to existing technologies, the track-guided vehicle proposed in the above technical solution, by setting independent rotatable guide wheels on the outside of each wheel assembly and mounting both on the slewing bearing, allows the guide wheels to prioritize sensing changes in track alignment as the vehicle travels along the track, triggering a steering action before the wheel assembly enters a curve. This "predictive" steering mechanism effectively alleviates the instability problem caused by the large weight and strong inertia of materials during turns, enabling the wheel assembly to complete attitude adjustment before entering a curve, thus achieving a smoother and safer steering process. The four guide wheels are respectively arranged on the outside of the corresponding wheel assembly along the direction of travel. Regardless of whether the guided vehicle is moving forward or backward, two guide wheels are always at the forefront in the current direction of travel, continuously sensing the track trajectory and guiding the wheel assembly to turn. This design allows the guided vehicle to automatically adapt to changes in track alignment without disassembly or reassembly during round trips, greatly improving the flexibility and automation level of the equipment, while also simplifying the operation process and improving overall operating efficiency. Because each wheel assembly and guide wheel is connected to the chassis via slewing bearings, it possesses excellent rotational freedom and structural strength. Therefore, it can not only withstand large loads but also maintain high operational accuracy and stability on complex paths. Compared to traditional guided vehicles that are only suitable for straight tracks, this application demonstrates greater adaptability and safety when dealing with complex conditions such as curves and intersecting paths, effectively reducing the probability of derailment accidents and extending the equipment's service life.

[0019] In summary, this application provides a more stable track-guided vehicle, which breaks through the limitations of traditional equipment in non-linear tracks and provides a more efficient and safer technical solution for material handling in modern logistics systems and intelligent manufacturing, with good market application prospects.

[0044] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0045] Reference Figures 1 to 5 As shown, an embodiment of this application proposes a track-guided vehicle, which may include: a chassis 1; a support 2, disposed above the chassis 1 for carrying materials; four slewing bearings 3, arranged in pairs at the bottom of the chassis 1; four wheel assemblies 4, rotatably mounted on the chassis 1 via corresponding slewing bearings 3, for cooperating with tracks configured on the site; and four guide wheels 5, rotatably mounted on the chassis 1 via corresponding slewing bearing shafts, each guide wheel 5 being disposed on the outer side of the corresponding wheel assembly 4 along the running direction, for guiding the corresponding wheel assembly 4 to run on a curved track;

[0046] Each wheel assembly 4 and each guide wheel 5 are steered on the chassis 1 via a corresponding slewing bearing 3.

[0047] Specifically, in the technical solution adopted in this application, a support 2 for carrying materials is configured above the chassis 1 so that the rail-guided vehicle can transport materials. At the bottom of the chassis 1, four wheel assemblies 4 and four guide wheels 5 are respectively installed through slewing bearings 3, so that the rail-guided vehicle can move on the track of the target site. It can be understood that each wheel assembly 4 and each guide wheel 5 turns on the track through a separate slewing bearing 3. In this application, each guide wheel 5 is located on the outer side of the corresponding wheel assembly 4 in the forward direction. Thus, the two wheel assemblies 4 at the front of the forward direction on the chassis 1 can sense the trajectory of the track first through the corresponding guide wheels 5. When entering the curve of the track, the two wheel assemblies 4 at the front of the forward direction can enter the turning preparation in advance through the guidance of the corresponding guide wheels 5, so that the rail-guided vehicle runs more stably on the track with a curved trajectory. During the operation of the rail-guided vehicle of this application, the probability of derailment accident when passing through the sharp curve of the track is effectively reduced.

[0048] It should be noted that in the rail-guided vehicle proposed in this application, since the four guide wheels 5 are located on the outer side of the corresponding wheel assembly 4 along the direction of travel, the wheel assembly 4 on each set of two slewing bearings 3 can serve as the front wheel assembly 4 of the rail-guided vehicle. It can be understood that whether the rail-guided vehicle moves forward or backward, the two guide wheels 5 guide the corresponding two wheel assemblies 4 to turn according to the travel trajectory of the track. It is not necessary to disassemble the rail-guided vehicle and reassemble it on the track of the target site. This allows the rail-guided vehicle to turn in advance by the guide wheels 5 guiding the corresponding wheel assembly 4 through the slewing bearing 3 when it travels back and forth on the track of the target site.

[0049] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, each group of two slewing bearings 3 are arranged side by side at the bottom of the chassis 1;

[0050] The slewing bearing 3 includes: a fixed member 31, which is installed at the bottom of the chassis 1; a rotating member 32, which is rotatably sleeved on the fixed member 31; a base plate 33, which is connected to the rotating member 32 and rotates synchronously with the rotating member 32; and each wheel assembly 4 and each guide wheel 5 are arranged on the corresponding base plate 33.

[0051] Specifically, in the technical solution adopted in this application, the fixing member 31 can be configured as a disc-shaped structure and fixedly installed on the chassis 1 by fasteners, while the rotating member 32 can be configured as a disc-shaped structure larger than the fixing member 31. The rotating member 32 is installed on the fixing member 31 in a sleeve manner, and the rotating member 32 can rotate based on the fixing member 31. A base plate 33 is also connected to the side of the rotating member 32 away from the chassis 1 for mounting the wheel assembly 4 and the guide wheel 5. That is, the four wheel assemblies 4 and four guide wheels 5 are respectively mounted on the corresponding slewing bearings 3 through the base plate 33. During the movement of the track-guided vehicle, the guide wheel 5 first senses the direction of travel of the track in front of the wheel assembly 4, so that the steering member rotates on the fixing member 31 based on the curvature angle of the track, thereby enabling the wheel assembly 4 located behind the guide wheel 5 to prepare for steering in advance.

[0052] It is important to note that when the track used in the rail-guided vehicle needs to change direction, curved curves are used for transportation safety reasons, and angled curves, such as right-angle curves, are not used. Therefore, the wheel assembly 4 and the guide wheel 5 can share a single component that provides steering function, namely the slewing bearing 3.

[0053] Furthermore, refer to Figure 3 and Figure 4As shown, in some embodiments, the wheel assembly 4 includes: a bearing seat 41, mounted on the side of the base plate 33 away from the rotating member 32; a first bearing component 42, with a shaft seat sleeved at both ends of the first bearing component 42; and a wheel 43, rotatably mounted on the bearing seat 41 via the first bearing component 42. The outer edge of the radial side of the wheel 43 has a first fitting portion 431 and a first limiting portion 432. The diameter of the first fitting portion 431 is smaller than the diameter of the first limiting portion 432. The first fitting portion 431 is used to contact the upper surface of the track, and the first limiting portion 432 is used to fit against one side of the track.

[0054] Specifically, in the technical solution adopted in this application, in order to enable the wheel assembly 4 to travel on the track of the target site, the wheel assembly 4 may include: a bearing seat 41 spaced apart on the side of the base plate 33 away from the rotating member 32, and a first bearing member 42 rotatably disposed on the bearing seat 41, and a wheel 43 for travel is mounted on the bearing seat 41 through the first bearing member 42. The wheel 43 rotates synchronously with the first bearing member 42, and the outer edge of the radial side of the wheel 43 is used to contact the track, thereby achieving the purpose of traveling on the track.

[0055] In a further embodiment, in order for the two parallel wheels 43 to cooperate with each other and move stably on the track in a supported manner, a first fitting part 431 and a first limiting part 432 are formed on the radial side of the wheel 43 in this application. The first fitting part 431 is used to contact the upper surface of the track so that the wheel 43 can roll on the track, while the first limiting part 432 is attached to one side of the track in an abutting manner, thereby assisting the first fitting part 431 to continuously contact the upper surface of the track. On the two parallel wheels 43, the two first limiting parts 432 are located on the opposite or back-to-back sides of the wheel 43 so that the two limiting parts can apply a supporting force to each other, thereby making the movement of the track-guided vehicle more stable.

[0056] Furthermore, refer to Figure 4 As shown, in some embodiments, the wheel assembly 4 further includes: two hinged posts 44 mounted on the surface of the rotating member 32 of the base plate 33, with one end of the two hinged posts 44 away from the base plate 33 hinged to the bearing seat 41 and located on the side of the bearing seat 41 close to the guide wheel 5; and two elastic elements 45 mounted on the surface of the rotating member 32 of the base plate 33, with the two elastic elements 45 elastically supported between the base plate 33 and the bearing seat 41 and located on the side of the bearing seat 41 away from the guide wheel 5.

[0057] Specifically, in the technical solution adopted in this application, the wheel assembly 4 also includes a shock-absorbing component, which is disposed between the base plate 33 and the bearing seat 41, to provide damping force between the bearing seat 41 and the base plate 33, so that the rail-guided vehicle can be buffered by the shock-absorbing component during the movement, so as to improve the stability of the material mounted on the support 2 during the transportation process. In this embodiment, the shock-absorbing component may include two hinged columns 44 and two elastic elements 45 supported between the base plate 33 and the bearing seat 41. The bottom ends of the two hinged columns 44 are fixedly connected to the base plate 33 and located on the side of the wheel 43 near the corresponding guide wheel 5. The outer ends of the two hinged columns 44 are connected to the bearing seat 41 in a hinged manner, so that the bearing seat 41 can be flipped based on the two hinged columns 44. The two elastic elements 45 are located on the side of the wheel 43 away from the corresponding guide wheel 5, so as to provide elastic support during the flipping process of the bearing seat 41 based on the two hinged columns 44. When the wheel 43 is subjected to external force, the bearing seat 41 can compress the two elastic elements to provide damping force to achieve the purpose of shock absorption, so that the material on the support 2 is more stable during the movement, and the stability of the rail-guided vehicle when transporting materials is improved.

[0058] Furthermore, refer to Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, it further includes: four adjusting mounting seats 6, each guide wheel 5 is disposed on the base plate 33 through a corresponding adjusting mounting seat 6; the adjusting mounting seat 6 includes: a sliding sleeve 61, which is mounted on the surface of the base plate 33 away from the rotating member 32, the sliding sleeve 61 has an adjusting hole 610, and the base plate 33 has a through hole that cooperates with the adjusting hole 610; a sliding column 62, which is slidably mounted in the adjusting hole 610, one end of the sliding column 62 has a limiting block 621 with a diameter larger than the adjusting hole 610, and the other end of the sliding column 62 is provided with a mounting lug 63; a second bearing component 64, which is disposed on the mounting lug 63, and the guide wheel 5 is rotatably mounted on the mounting lug 63 through the second bearing component 64.

[0059] Specifically, in the technical solution adopted in this application, each guide wheel 5 rests naturally on the track of the target site by its own weight, which is achieved by a corresponding adjusting mounting seat 6. The adjusting mounting seat 6 may include: a sliding sleeve 61 and a sliding column 62 slidably disposed in the sliding sleeve 61. The sliding sleeve 61 is mounted on the side surface of the base plate 33 opposite to the rotating member 32 by fasteners. The sliding sleeve 61 may also be integrally formed with the base plate 33. The sliding sleeve 61 has an adjusting hole 610 that extends vertically through the sliding sleeve 61, and the base plate 33 also has a through hole for engaging the adjusting hole 610; while the sliding column 62... The sliding column 62 is slidably disposed in the adjustment hole 610. One end of the sliding column 62 is formed with a limiting block 621, the diameter of which is larger than that of the adjustment hole 610. The other end of the sliding column 62 is provided with a mounting lug 63, the diameter of which is larger than that of the adjustment hole 610. The mounting lug 63 and the limiting block 621 limit the maximum sliding range of the sliding column 62 in the adjustment hole 610. The guide wheel 5 is rotatably disposed on the mounting lug 63 through the second bearing component 64. Thus, the guide wheel 5 is positioned on the track in a naturally drooping manner through the cooperation of the sliding column 62 and the sliding sleeve 61, which is used to guide the corresponding wheel 43 to turn in advance according to the curved track.

[0060] Furthermore, refer to Figure 4 As shown, in some embodiments, the outer edge of the radial side of the guide wheel 5 has a second fitting portion 51 and a second limiting portion 52. The diameter of the second fitting portion 51 is smaller than the diameter of the second limiting portion 52. The second fitting portion 51 is used to contact the upper surface of the track, and the second limiting portion 52 is used to fit against one side of the track.

[0061] Specifically, in the technical solution adopted in this application, in order to reduce the probability of derailment between the guide wheel 5 and the track, the guide wheel 5 adopts the same structure as the wheel 43. A second engaging portion 51 and a second limiting portion 52 are provided on the outer edge of the radial side of the guide wheel 5. The diameter of the second engaging portion 51 is smaller than the diameter of the second limiting portion 52. Therefore, when the guide wheel 5 is positioned on the track, the second engaging portion 51 contacts the upper surface of the track, while the second limiting portion 52 adheres to one side surface of the track. In use, since the guide wheels 5 on a set of two slewing bearings 3 are arranged side-by-side, the second limiting portions 52 on the two guide wheels 5 can apply a supporting force to each other, thereby allowing the guide wheel 5 to continuously sit on the track. The probability of derailment of the guide wheel 5 is reduced by the restriction of the second limiting portion 52.

[0062] Furthermore, refer to Figure 3 As shown, in some embodiments, it further includes: a linkage component 7, connected between each group of two slewing bearings 3, the two slewing bearings 3 rotating synchronously through the linkage component 7.

[0063] The linkage assembly 7 includes: four joint components 71, which are respectively hinged on the base plate 33 of the four slewing bearings 3; and two connecting rods 72, which are respectively connected to two joint components 71 on a set of two slewing bearings 3, so that the two slewing bearing shafts rotate synchronously through the cooperation of the two joint components 71 and the corresponding connecting rods 72.

[0064] Specifically, in the technical solution adopted in this application, the two slewing bearings 3 in a group need to rotate synchronously, that is, the two wheel assemblies 4 installed on the two slewing bearings in the same group can also rotate synchronously. To achieve this function, a linkage assembly 7 is set between the two slewing bearings 3 in the same group, so that when one slewing bearing 3 rotates, the linkage assembly 7 drives the other slewing bearing 3 to rotate synchronously. In this embodiment, a connecting rod 72 is connected between the slewing bearings 3 in the same group, so that the slewing bearings 3 in the same group can be driven to rotate synchronously through the connecting rod 72. In order to adapt to the rotation angle of the two slewing bearings 3, a connector component 71 is also installed on the base plate 33 in the slewing bearing 3 in a hinged manner, so as to connect the two ends of the corresponding connecting rod 72 through the connector component 71. The connector component 71 can be a fisheye connector, which is installed on the side surface of the base plate 33 of the four slewing bearings 3 near the rotating component 32.

[0065] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, it further includes: two drive mechanisms 8, disposed on two of the wheel assemblies 4, for driving the wheels 43 in the corresponding wheel assemblies 4 to rotate.

[0066] Furthermore, refer to Figure 3 As shown, in some embodiments, the drive mechanism 8 includes: a reduction transmission assembly 81, mounted on one side of the corresponding bearing housing 41, the reduction transmission assembly 81 having an output end and an input end, the output end being synchronously rotatably connected to the corresponding first bearing component 42; and a drive motor 82, mounted on the reduction transmission assembly 81, the output shaft of the drive motor 82 being synchronously rotatably connected to the input end, so that the rotational force of the output shaft is reduced by the reduction transmission assembly 81 and then applied to the first bearing component 42.

[0067] Specifically, in the technical solution adopted in this application, in order to further enable the rail-guided vehicle of this application to travel on the track of the target site, the rail-guided vehicle also includes two drive mechanisms 8 for driving the wheels 43 in the partial wheel assembly 4 to rotate. In order to make the structure of the rail-guided vehicle more balanced, one drive mechanism 8 can be configured on the wheel assembly 4 on the left side of one end of the chassis 1, and the other drive mechanism 8 can be configured on the wheel assembly 4 on the right side of the other end of the chassis 1. The drive mechanisms 8 drive the wheels 43 on the two wheel assemblies 4 to rotate, thereby enabling the rail-guided vehicle to travel on the track of the target site. In this embodiment, the drive mechanism 8 may include a reduction transmission assembly 81 and a drive motor 82. The reduction transmission assembly 81 has an output end and an input end. The housing of the drive motor 82 is fixed on the reduction transmission assembly 81, and the output shaft of the drive motor 82 is configured at the input end of the reduction transmission assembly 81. The output end of the reduction transmission assembly 81 is connected to the corresponding first bearing component 42 to transmit the rotational driving force on the output shaft of the drive motor 82 to the first bearing component 42. In this embodiment, the reduction transmission assembly 81 may adopt a reduction gear transmission. The transmission principle of the reduction gear is to receive the rotational driving force of the drive motor 82 through the input gear and transmit the rotational driving force to the first bearing component 42 through the output gear. The size of the input gear is smaller than the size of the output gear to achieve the purpose of deceleration. This technology belongs to the prior art and will not be described in detail. By adjusting the rotation frequency of the drive motor 82 output to the first bearing component 42 through the reduction transmission component 81, the controllability of the rotation driving force of the drive motor 82 is effectively improved, making the rail-guided vehicle more stable during travel and preventing the wheel component 4 from slipping on the track due to excessive rotation speed.
