[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of the present invention.

[0061] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0062] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0063] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0064] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0065] In order to more clearly reflect the technical solution of the present application, the relevant technology is first further explained by taking the cloth car in the cigarette production process as an example.

[0066] A material distribution vehicle is a small vehicle used for material distribution. In the cigarette production process, material distribution vehicles are often used, for example, to distribute materials to a storage cabinet or a cabinet feeder waiting for material distribution mechanism. Generally, an overhead guide rail is provided above the storage cabinet or the cabinet feeder waiting for material distribution mechanism, and the material distribution vehicle is set on the guide rail to become a rail vehicle (i.e., a small vehicle that travels along the guide rail).

[0067] Figure 1 A structure of a fabric car is shown. Figure 1 The material distributing vehicle 201 includes a vehicle body 30, a feeding mechanism (not shown in the figure), and wheels 40. The feeding mechanism such as a conveyor belt is arranged above the vehicle body 30, and is used to transport materials after the material distributing vehicle 201 runs to the destination, so as to realize the material distributing function. The wheels 40 (specifically, nylon wheels) are arranged below the vehicle body 30, and are used to contact with the guide rails, and realize the movement of the material distributing vehicle 201 on the guide rails by rolling along the guide rails.

[0068] Generally, a plurality of groups of wheels 40 are arranged on the vehicle body 30 at intervals along the length direction of the vehicle body 30. Each group of wheels 40 includes two wheels 40 located on both sides of the width direction of the vehicle body 30. The two wheels 40 in each group of wheels 40 are connected by an axle 60. The axle 60 is supported by a bearing seat 70 installed on the vehicle body 30 to achieve a rotatable connection with the vehicle body 30. In addition, a wheel disc 50 is also provided on one side of each wheel 40 close to the vehicle body 30. The diameter of the wheel disc 50 is larger than the diameter of the wheel 40. When running normally on the guide rail, the wheel 40 is pressed against the upper surface of the guide rail, and the wheel disc 50 extends below the upper surface of the guide rail and is stuck on the inner side of the inner edge of the guide rail to limit the wheel 40 in the width direction of the vehicle body 30.

[0069] During operation, the wheels 40 of the material distributing vehicle 201 roll on the guide rails to enable the material distributing vehicle 201 to move on the guide rails. After reaching the destination, the feeding mechanism on the material distributing vehicle 201 starts to work, and feeds materials such as tobacco into the storage cabinet or cabinet feeder below to wait for the material distributing mechanism.

[0070] As the running time increases, the fabric car 201 is prone to the following problems:

[0071] (1) The wheel 40 is worn, which affects the normal operation of the material distribution vehicle 201. In this case, the wheel 40 needs to be disassembled and replaced.

[0072] (2) The axle 60 of the wheel 40 is subjected to a large torque during reciprocating switching. After long-term operation, stress concentration occurs at the welding point between the axle head and the intermediate axle tube of the axle 60, and the axle breaks under the action of the alternating load generated by the reciprocating operation of the material distribution vehicle, causing equipment failure and production process shutdown. At this time, the wheel 40 needs to be disassembled and the rotating shaft 60 needs to be replaced.

[0073] It can be seen that the wheels of the cloth truck need to be disassembled and assembled due to wear and axle breakage. For example, after the wheel is worn to a certain extent, the old wheel needs to be disassembled and a new wheel needs to be installed. For another example, when the wheel does not need to be replaced but the axle is broken, the wheel also needs to be disassembled to facilitate the disassembly of the old axle and the installation of the new axle. After the new axle is installed, the wheel needs to be reinstalled. For another example, when both the wheel and the axle need to be replaced, the old wheel and the old axle need to be disassembled and the new wheel and axle need to be installed. Therefore, in the present invention, the disassembly and assembly of the wheel includes both the case of disassembling and replacing the wheel (i.e., removing the old wheel and installing a new wheel), and also includes the case of disassembling and reassembling the wheel without replacing it (i.e., disassembling and assembling the same wheel).

[0074] In the related art, the guide rail is an integral structure and cannot be disassembled. Since the wheel is pressed on the guide rail, the wheel cannot be directly disassembled. Therefore, the staff has to use long wooden bars or jacks to pry the wheel to be disassembled, and use the principle of leverage to lift the wheel so that the wheel is above the upper surface of the guide rail before disassembling the wheel.

[0075] The above method is inconvenient to operate, time-consuming and laborious. In particular, the cloth carts used in the tobacco industry are long, wide, large in size and heavy in weight, so the above method is more difficult to use. On the one hand, when using long wooden strips to lift, multiple workers are required to press the wooden strips with great effort and maintain the pressing posture for a long time, which consumes a lot of physical strength, and the long wooden strips are easy to slip and break, which is inefficient and has poor safety. On the other hand, when using a jack to lift, the jack is prone to pressure relief and failure, and there are also problems of low efficiency and poor safety. On the other hand, due to limitations in the layout of the process route and other reasons, it is impossible to build a direct maintenance platform, which results in the need to use tools such as aerial lifts or ladders when replacing some wheels, which is time-consuming and labor-intensive, and also affects the efficiency of wheel disassembly and assembly.

[0076] In addition to the cloth carts used in the tobacco industry, other rail cars running on overhead rails, especially larger rail cars, also face the problem of inconvenient disassembly and assembly of such wheels.

[0077] In view of the above situation, the present invention provides a guide rail system, a rail vehicle system and a method for disassembling and assembling a rail vehicle wheel, which changes the wheel disassembling and assembling process based on the improvement of the guide rail system structure to facilitate the disassembly and assembly of the rail vehicle wheels.

[0078] Figure 1-9 The structure of the rail vehicle system and the guide rail system of the present invention and the process of disassembling and assembling the wheels of the rail vehicle are exemplarily shown.

[0079] Reference Figure 1 The rail vehicle system 300 of the present invention includes a rail system 100 and a rail vehicle 200. The rail vehicle 200 is arranged on the rail system 100, supported by the rail system 100, and moves under the guidance of the rail system 100. The rail vehicle 200 can be a small vehicle such as a material distribution vehicle 201 that moves on the rail.

[0080] Among them, refer to Figure 1-8 In some embodiments, the guide rail system 100 includes a guide rail device 10 and a support device 20, etc.

[0081] The support device 20 supports the guide rail device 10 above the ground, realizing an overhead setting of the guide rail device 10. The guide rail device 10 is arranged on the support device 20, and is used to support the rail vehicle 200 and guide the rail vehicle 200 to travel. The upper surface of the guide rail device 10 contacts the wheels 40 of the rail vehicle 200 to support and guide the rail vehicle 200.

[0082] Reference Figure 1 In some embodiments, the supporting device 20 includes a plurality of groups of legs 3, which are arranged at intervals along the length direction of the guide rail device 10 (which is also the length direction of the rail vehicle 200), and each group of legs 3 includes two legs 3, and the two legs 3 in each group of legs 3 are relatively arranged on both sides of the width direction of the guide rail device 10 (which is also the width direction of the rail vehicle 200).

[0083] Reference Figure 1-8 In some embodiments, the guide rail device 10 includes a guide rail 1, and the guide rail device 10 contacts the wheels 40 of the rail vehicle 200 through the guide rail 1 to achieve support and operation guidance for the rail vehicle 200. At this time, the upper surface of the guide rail 1 is the upper surface of the guide rail device 10.

[0084] When the guide rail 1 is thick and strong enough, the guide rail device 10 may only include the guide rail 1 . In this case, the support device 20 directly contacts the lower surface of the guide rail 1 to support the guide rail device 10 .

[0085] And refer to Figure 1-8 In some embodiments, the thickness of the guide rail 1 is small, and its own strength is difficult to support the rail vehicle 200. In this case, the guide rail device 10 may further include a channel steel 2, which is supported below the guide rail 1 to improve the bearing capacity of the guide rail device 10 and achieve more reliable support for the rail vehicle 200. At this time, the support device 20 is supported below the channel steel 2 and contacts the lower surface of the channel steel 2. By supporting the channel steel 2, the guide rail 1 is indirectly supported, thereby achieving support for the guide rail device 10.

[0086] In order to facilitate the disassembly and assembly of the wheels 40 of the rail vehicle 200, in the present invention, the guide rail device 10 no longer adopts an integrated structure, but a split structure. Figure 1-8 In some embodiments, the guide rail device 10 includes a first support segment 10a, a second support segment 10b, and a third support segment 10c. The first support segment 10a, the second support segment 10b, and the third support segment 10c are arranged in sequence along the length direction of the guide rail device 10, and the second support segment 10b is detachably connected to the first support segment 10a and the third support segment 10c, that is, the second support segment 10b is detachably connected between the first support segment 10a and the third support segment 10c. For example, in some embodiments, the second support segment 10b is connected to the first support segment 10a and the third support segment 10c by threaded connectors such as bolts.

[0087] When the guide rail device 10 only includes the guide rail 1, the first supporting segment 10a includes the first guide rail segment 11 of the guide rail 1, the second supporting segment 10b includes the second guide rail segment 12, the third supporting segment 10c includes the third guide rail segment 13, and the second guide rail segment 12 is detachably connected between the first guide rail segment 12 and the third guide rail segment 13.

[0088] When the guide rail device 10 includes the guide rail 1 and the channel steel 2, the first support segment 10a includes the first guide rail segment 11 of the guide rail 1 and the first channel steel segment 21 of the channel steel 2, the second support segment 10b includes the second guide rail segment 12 of the guide rail 1 and the second channel steel segment 22 of the channel steel 2, and the third support segment 10c includes the third guide rail segment 13 of the guide rail 1 and the third channel steel segment 23 of the channel steel 2, and the second guide rail segment 12 is detachably connected between the first guide rail segment 12 and the third guide rail segment 13, and the second channel steel segment 22 is detachably connected between the first channel steel segment 21 and the third channel steel segment 23. The second channel steel segment 22 can be located directly below the second guide rail segment 12 and has the same length as the second guide rail segment 12.

[0089] The detachable second support section 10b can be used as a special wheel disassembly and assembly area, that is, the wheel disassembly and assembly operation is performed in the area corresponding to the second support section 10b each time. At this time, the second support section 10b can be set at a location that is convenient for building a maintenance platform to reduce the dependence on an aerial lift or a stepladder, omit the steps of starting an aerial lift or moving a stepladder, and simplify the wheel disassembly and assembly process. Among them, the area corresponding to the second support section 10b can be called a disassembly and assembly area for the convenience of description.

[0090] Furthermore, during the wheel disassembly and assembly process, the wheel 40 to be disassembled can be conveniently suspended in the air by removing the second support section 10b, thereby solving the problem of inconvenience in disassembly and assembly of the wheel due to interference of the guide rail device 10. Since there is no need to use wooden strips or jacks to lift the rail car 200, it is simpler and more convenient, which is conducive to reducing the labor intensity of the staff and improving the disassembly and assembly efficiency and safety of the rail car wheel.

[0091] Specifically, refer to Figure 2-7 Based on the second support section 10b provided, the wheel disassembly and assembly process can be as follows:

[0092] First, refer to Figure 2 , operate the rail car 200 so that the wheel 40 to be disassembled is located near the second support section 10b. The operation of the rail car 200 can be controlled by operating a switch (such as an isolating switch) corresponding to the rail car 200. For example, for a material distribution vehicle 201 for distributing materials to a storage cabinet, its switch can be set on the storage cabinet, and during the process of disassembling and assembling the wheel 40, the operator can trigger it by jogging to control the start and stop and the running distance of the material distribution vehicle 201.

[0093] Then, refer to Figure 3 , the second support segment 10b is removed from between the first support segment 10a and the third support segment 10c. For example, when the guide rail device 10 only includes the guide rail 1, the second guide rail segment 12 is removed from between the first guide rail segment 11 and the third guide rail segment 13. Alternatively, when the guide rail device 10 includes both the guide rail 1 and the channel steel 2, not only the second guide rail segment 12 is removed from between the first guide rail segment 11 and the third guide rail segment 13, but also the second channel steel segment 22 is removed from between the first channel steel segment 21 and the third channel steel segment 23.

[0094] Afterwards, refer to Figure 4, control the rail vehicle 200 to continue running until the wheel 40 to be removed is located between the first support segment 10a and the third support segment 10c, for example, in the middle of the disassembly and assembly area. Since the second support segment 10b has been removed at this time, the wheel 40 to be removed is no longer pressed on the rail device 10, but is suspended in the air. After the wheel 40 to be removed runs between the first support segment 10a and the third support segment 10c, the isolating switch can be turned to the 0 position, and brake blocks can be placed between the other wheels, so that the rail vehicle 200 can more reliably remain stationary during the subsequent wheel disassembly and assembly process.

[0095] Next, the wheel 40 to be disassembled is disassembled, and then the wheel 40 is installed. Since the second support section 10b has been disassembled, there is an operating space under the wheel 40, so the wheel can be easily disassembled and assembled. The installation of the wheel 40 can be the installation of a new wheel 40, or the reinstallation of the original wheel 40 after the axle 60 is replaced. In addition, when the axle 60 is replaced, the bearing seat 70 supporting the axle 60 can be pre-tightened before installing the new axle 60, and after the subsequent rail vehicle 200 leaves the disassembly and assembly area and the height position of the installed wheel is adjusted to be consistent with the height position of other wheels, the pre-tightened bearing seat 70 can be locked.

[0096] Then, refer to Figure 5-6 , the second support segment 10b is connected between the first support segment 10a and the third support segment 10c. For example, when the guide rail device 10 only includes the guide rail 1, the second guide rail segment 12 is connected between the first guide rail segment 11 and the third guide rail segment 13. Alternatively, when the guide rail device 10 includes both the guide rail 1 and the channel steel 2, not only is the second guide rail segment 12 connected between the first guide rail segment 11 and the third guide rail segment 13, but the second channel steel segment 22 is also connected between the first channel steel segment 21 and the third channel steel segment 23.

[0097] Afterwards, refer to Figure 7 , control the rail vehicle 200 to move away from the second supporting section 10b.

[0098] It can be seen from the above process that based on the second supporting section 10b, there is no need to use wooden bars or jacks to lift the rail car 200, and the wheel 40 can be easily disassembled and assembled. Since it can avoid the occurrence of problems such as multiple workers pressing the wooden bars with great force for a long time, the wooden bars slipping or breaking, and the jack pressure relief failure, the wheel disassembly and assembly process is more convenient, efficient and safer.

[0099] In the above process, after the wheel 40 is installed, the second support section 10b is installed first, and then the rail vehicle 200 is controlled to drive away from the second support section 10b. This is mainly to use the second support section 10b to support and guide the rail vehicle 200 when the rail vehicle 200 drives away from the disassembly and assembly area, so that the rail vehicle 200 can drive away from the disassembly and assembly area more quickly and smoothly.

[0100] However, since the lowest point of the wheel 40 in the disassembly and assembly area is lower than the upper surfaces of the first support segment 10a and the third support segment 10c after the wheel 40 is installed, and there is a positive pressure between the rail vehicle 200 and the guide rail device 10, if the second support segment 10b whose upper surface is flush with the upper surfaces of the first support segment 10a and the third support segment 10c is directly installed, it is easy to cause interference between the second support segment 10b and the wheel 40, making it difficult to install the second support segment 10b. Therefore, in order to facilitate the installation of the second support segment 10b after the wheel 40 is installed, the upper surface of the second support segment 10b installed can be recessed downward relative to the upper surfaces of the first support segment 10a and the third support segment 10c, so as to reduce or even eliminate the interference between the second support segment 10b and the wheel 40 during the reinstallation process, thereby reducing the difficulty of installing the second support segment 10b at this stage.

[0101] In order to make the upper surface of the second support segment 10b installed after the wheel 40 is installed recessed downward relative to the upper surfaces of the first support segment 10a and the third support segment 10c, in some embodiments, the second guide rail segment 12 is configured to include a first rail body 121, and the upper surface of the first rail body 121 is recessed downward. In this case, the second rail segment 12 may only include the first rail body 121, and the second rail segment 12 disassembled and assembled during the wheel disassembly and assembly process is only the disassembly and assembly of the first rail body 121, that is, before the wheel 40 drives to the disassembly and assembly area, the second rail segment 12 is disassembled from between the first rail segment 11 and the third rail segment 13, which means that the first rail body 121 is disassembled from between the first rail segment 11 and the third rail segment 13, and at the same time, when the wheel 40 is in the disassembly and assembly area, the second rail segment 12 is connected between the first rail segment 11 and the third rail segment 13, which means that the first rail body 121 is reconnected between the first rail segment 11 and the third rail segment 13. It can be seen that in these embodiments, whether in normal state or during wheel disassembly and assembly, the first rail body 121 is connected to the first rail segment 11 and the third rail segment 13.

[0102] Since the upper surface of the first rail body 121 is not a plane but is concave downward, when connected to the first guide rail segment 11 and the third guide rail segment 13, the heights of the two ends of the first rail body 121 are consistent with the heights of the first guide rail segment 11 and the third guide rail segment 13, and the middle area of ​​the upper surface of the first rail body 121 is lower than the upper surfaces of the first guide rail segment 11 and the third guide rail segment 13, so that after the installation of the wheel 40 is completed and the first rail body 121 needs to be installed, the interference between the upper surface of the first rail body 121 and the wheel 40 is reduced. Even when the concave depth of the first rail body 121 is sufficient, the upper surface of the first rail body 121 can be lower than the lowest point of the wheel 40 located in the disassembly and assembly area, thereby completely eliminating the interference between the first rail body 121 and the wheel 40 during the installation process, thereby effectively reducing the difficulty of installing the second guide rail segment 12.

[0103] In the case where the upper surface of the first rail body 121 is concave downward, the upper surface of the first rail body 121 can be further configured to be arc-shaped. The upper surface of the first rail body 121 is configured to be an arc-shaped concave surface, so that the wheels 40 can rotate along the arc-shaped concave surface when the rail vehicle 200 leaves the assembly and disassembly area, thereby smoothly realizing the departure of the rail vehicle 200.

[0104] Alternatively, in order to make the upper surface of the reinstalled second support segment 10b concave downward relative to the upper surfaces of the first support segment 10a and the third support segment 10c, in other embodiments, the second guide rail segment 12 is configured to include a first rail body 121 and a second rail body 122, the upper surface of the first rail body 121 is a plane, the upper surface of the second rail body 122 is concave downward, and the first rail body 121 and the second rail body 122 are alternately connected between the first guide rail segment 11 and the third guide rail segment 13. The second rail body 122 is connected between the first guide rail segment 11 and the third guide rail segment 13 only after the wheel 40 is installed and during the process of the rail vehicle 200 leaving the disassembly and assembly area, and the first rail body 121 is connected between the first guide rail segment 11 and the third guide rail segment 13 at other times. The advantage of this configuration is that it can not only reduce the difficulty of installing the second guide rail segment 12 when the wheel 40 is in the disassembly and assembly area, but also improve the running stability of the rail vehicle 200 under normal conditions.

[0105] Because, on the one hand, when the wheel 40 is in the disassembly and assembly area, the second rail body 122 with a downwardly concave upper surface is installed, and the interference between the second rail body 122 and the wheel 40 is reduced or even eliminated. Figure 5-6In the illustrated embodiment, when connected between the first rail section 11 and the third rail section 13, the lowest point of the upper surface of the second rail body 122 is located below the lowest point of the wheel 40, and there is a gap D between the lowest point of the wheel 40, so the second rail body 122 is easy to install. On the other hand, under normal conditions, that is, when the wheel is not being disassembled, the connection between the first rail section 11 and the third rail section 13 is no longer the second rail body 122 with a downwardly concave upper surface, but the first rail body 121 with a flat upper surface. Therefore, the upper surface of the entire guide rail 1 is flat and there are no potholes, so that bumps can be avoided during the operation of the rail vehicle 200, and the running stability of the rail vehicle 200 can be effectively improved.

[0106] In the embodiments where the second rail segment 12 includes the first rail body 121 and the second rail body 122, before the wheel 40 drives to the disassembly and assembly area, the second rail segment 12 is disassembled from between the first rail segment 11 and the third rail segment 13, which means that the first rail body 121 is disassembled from between the first rail segment 11 and the third rail segment 13; and when the wheel 40 is in the disassembly and assembly area, the second rail segment 12 is connected between the first rail segment 11 and the third rail segment 13, which means that the second rail body 122 is connected between the first rail segment 11 and the third rail segment 13; and, with reference to Figure 8 After the rail vehicle 200 leaves the disassembly and assembly area, the second rail body 122 needs to be removed and the first rail body 121 needs to be reconnected between the first guide rail segment 11 and the third guide rail segment 13 to achieve the reset of the first rail body 121 so that the upper surface of the guide rail 1 is flat under normal conditions.

[0107] The upper surface of the second rail body 122 can be arc-shaped. The upper surface of the second rail body 122 is set as an arc-shaped concave surface, which is convenient for the wheels 40 to rotate and climb along the arc-shaped concave surface when the rail vehicle 200 leaves the disassembly and assembly area, thereby improving the smoothness and stability of the rail vehicle 200 leaving.

[0108] In the above embodiments, since the guide rail device 10 is no longer an integrated structure, but a detachable split structure, in order to improve the bearing capacity of the guide rail device 10 and enhance the strength of the entire guide rail system 100, refer to Figure 2-8In some embodiments, an auxiliary support 5 is added to the support device 20 to support the two ends of the second support segment 10b. The auxiliary support 5 includes a horizontal portion 51 and two vertical portions 52. The horizontal portion 51 is connected between the two legs 3 located on both sides of the second support segment 10b, and the two vertical portions 52 are arranged on the horizontal portion 51 at intervals from each other and are respectively located directly below the two ends of the second support segment 10b. The two vertical portions 52 are in contact with the lower surfaces of the two ends of the second support segment 10b. For example, when the second support segment 10b includes the second channel steel segment 22, the two vertical portions 52 are in contact with the lower surfaces of the two ends of the second channel steel segment 22 to support the two ends of the second support segment 10b.

[0109] By further providing auxiliary supports 5 on the basis of the support legs 3 to specifically support the two ends of the second support segment 10b, the risk of accidental breakage of the guide rail device 10 at the two ends of the second support segment 10b can be effectively reduced, the supporting capacity of the guide rail device 10 for the rail vehicle 200 can be enhanced, and the working reliability of the guide rail system 100 can be improved.

[0110] In addition, in the above embodiments, the length of the second supporting segment 10b can be set to be smaller than the distance between two adjacent sets of wheels 40 of the rail vehicle 200, so that during the wheel disassembly and assembly process, only the wheels 40 to be disassembled are in the disassembly and assembly area, and the other wheels are located outside the disassembly and assembly area, supported by the first supporting segment 10a and the third supporting segment 10c, thereby providing more stable support for the rail vehicle 200.

[0111] It can be seen that by optimizing the structure of the guide rail system 100, the wheels of the rail car 200 can be quickly disassembled and assembled without lifting the rail car 200, which is simple and convenient, saves time and effort, and can effectively reduce manpower occupation, reduce labor intensity, improve the maintenance efficiency of the rail car, and improve the repair safety of the rail car.
