Abstract
Description
[0001] This case is a divisional application based on the invention patent filed on November 25, 2025, with application number 202511740504.1 and title "A Track Structure for an Agricultural Rail Vehicle". Technical Field
[0002] This invention relates to the field of agricultural rail vehicle technology, and in particular to an agricultural rail vehicle track structure and its installation and disassembly method. Background Technology
[0003] Agricultural railcars have solved the transportation difficulties in mountainous and hilly areas, facilitating the transport of agricultural products and other goods in such terrain. The track is a crucial component of monorail transport. During track layout, it's often necessary to adapt to the terrain. Because the track is formed by connecting individual guide rails end-to-end with a connecting pipe, disassembly is difficult. The middle guide rails are often jammed, leaving no room for disassembly from the middle; disassembly must begin from the beginning and end. Since a track can be hundreds or even thousands of meters long, this structure significantly impacts disassembly efficiency and hinders track maintenance and replacement.
[0004] Traditional agricultural railcar tracks are generally fixed and have a long service life. With the development of technology, railcars are now used in a variety of scenarios, such as crop rotation in mountainous areas, which requires the tracks to be quickly disassembled and moved to the required location. The disassembly efficiency of traditional railcar tracks cannot meet the requirements of use. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a track structure for an agricultural railcar that can be quickly disassembled.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an agricultural rail vehicle track structure, including a track body, the track body being composed of multiple guide rails connected end to end in sequence, the track body including a first guide rail, a second guide rail, a first pin and a second pin, the first guide rail and the second guide rail being connected by a connecting sleeve, the two ends of the connecting sleeve being inserted into the first guide rail and the second guide rail respectively. The first guide rail is provided with a first pin hole, and the first pin passes through the first pin hole and one end of the connecting sleeve; the second guide rail is provided with a second pin hole, and the second pin passes through the second pin hole and the other end of the connecting sleeve; the second pin hole is an elongated through hole, and the length of the second pin hole is greater than the length of the connecting sleeve inserted into the first guide rail.
[0007] The beneficial effects of this invention are as follows: After the track layout of the railcar is used, it needs to be moved to other areas for short-term disuse. In traditional railcars, the two ends of the guide rail in the middle are stuck, leaving no room for disassembly. Disassembly cannot be started from the middle of the track and can only be started from the beginning and end of the track. However, the length of existing tracks is getting longer and longer, even reaching tens of kilometers. Disassembly from the beginning and end is too inefficient. In the railcar structure of this invention, an elongated second pin hole is set. During disassembly, the second pin drives the connecting sleeve to retract completely into the second guide rail. At this time, the first and second guide rails can be easily separated and disassembled. The above disassembly and separation action can be used at any section of the track. If there is enough manpower, the track can be disassembled quickly, without being limited to the beginning and end sections. This improves the disassembly efficiency of the track and facilitates track maintenance and replacement. Attached Figure Description

[0009] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0010] After the track layout of a railcar is put into use, it needs to be moved to another area for short-term disuse. Traditional tracks have guide rails in the middle that are jammed at both ends, leaving no room for disassembly. Disassembly cannot be started from the middle of the track; it can only be started from the beginning and end. However, the length of existing tracks is increasingly long, even reaching tens of kilometers, making disassembly from the beginning and end inefficient. This invention features a long, narrow second pin hole. During disassembly, the second pin causes the connecting sleeve to retract completely into the second guide rail. At this point, the first and second guide rails can be easily separated and disassembled. This disassembly and separation action can be performed on any section of the track.
[0011] Please refer to Figures 1 to 4 An agricultural rail vehicle track structure includes a track body, which is composed of multiple guide rails connected end to end. The track body includes a first guide rail 1, a second guide rail 3, a first pin 11, and a second pin 31. The first guide rail 1 and the second guide rail 3 are connected by a connecting sleeve 2, and the two ends of the connecting sleeve 2 are respectively inserted into the first guide rail 1 and the second guide rail 3. The first guide rail 1 is provided with a first pin hole 12, and a first pin 11 passes through the first pin hole 12 and one end of the connecting sleeve 2; the second guide rail 3 is provided with a second pin hole 32, and a second pin 31 passes through the second pin hole 32 and the other end of the connecting sleeve 2; the second pin hole 32 is an elongated through hole, and the length of the second pin hole 32 is greater than the length of the connecting sleeve 2 inserted into the first guide rail 1.
[0012] The beneficial effects of this invention are as follows: After the track layout of the railcar is used, it needs to be moved to other areas for short-term use. In traditional railcars, the two ends of the guide rail in the middle are stuck, leaving no room for disassembly. Disassembly cannot be started from the middle of the track and can only be started from the beginning and end of the track. However, the length of existing tracks is getting longer and longer, sometimes tens of kilometers. Disassembling from the beginning and end is too inefficient. In the railcar structure of this invention, a long strip-shaped second pin hole 32 is set. During disassembly, the second pin 31 drives the connecting sleeve 2 to retract completely into the second guide rail 3. At this time, the first guide rail 1 and the second guide rail 3 can be easily separated and disassembled. The above disassembly and separation action can be used at any section of the track. If there is enough manpower, the track can be disassembled quickly, without being limited to the beginning and end sections. This improves the disassembly efficiency of the track and facilitates track maintenance and replacement.
[0013] Furthermore, in the above-mentioned agricultural railcar track structure, the track body also includes a connecting plate 4, a connecting rod 5, and a horizontal connecting member; the first pin 11 is fixedly connected to the horizontal connecting member, and the horizontal connecting member includes a first vertical connecting pipe 6 (the horizontal connecting member can be a pipe or other connection structure); the connecting plate 4 connects to multiple ground anchors, and the connecting plate 4 is provided with a second vertical connecting pipe 7 (optional); one end of the connecting rod 5 is sleeved on the first connecting pipe 6, and the other end is sleeved on the second connecting pipe 7.
[0014] As described above, traditional tracks are directly connected to ground anchors at their lower ends. These anchors need to be driven 80-100 cm into the ground to provide sufficient rigidity, and this deep driving makes disassembly difficult. This invention, by incorporating a connecting plate 4, provides greater support and significantly reduces the required anchor depth from the traditional 80-100 cm to 30-50 cm, thus providing sufficient rigidity. This greatly reduces installation difficulty and cost. Furthermore, the connection between the first connecting pipe 6 and the second connecting pipe 7 and the connecting rod 5 facilitates the installation and disassembly of the support components. This invention improves the disassembly efficiency of the track.
[0015] Furthermore, in the above-mentioned agricultural railcar track structure, the two ends of the second pin hole 32 are respectively provided with fixing holes 321 adapted to the second pin, the middle part of the second pin hole 32 is an elongated through hole with a width smaller than (can be the same as) the diameter of the fixing hole 321, the second pin 31 includes a pin shaft, and the pin shaft is provided with a notch 311 corresponding to the elongated through hole (the notch may not be present), the notch 311 is used for the second pin 31 to slide into the elongated through hole.
[0016] As described above, the above limitations enable the second pin 31 to achieve a fixing function through the fixing hole 321, and also to move along the elongated through hole through the notch 311, providing guidance and limiting for the movement of the connecting sleeve 2, and ensuring the stability and reliability of the disassembly process.
[0017] Furthermore, in the above-mentioned agricultural railcar track structure, there are two first connecting pipes 6, two second connecting pipes 7 corresponding to the first connecting pipes 6, and two connecting rods 5 corresponding to the first connecting pipes 6.
[0018] As described above, the dual-connecting-tube design provides a more balanced distribution of support force, preventing the track from twisting or shifting under stress.
[0019] Furthermore, in the above-mentioned agricultural railcar track structure, a connecting rod pin 61 is threadedly connected to the side wall of the first connecting pipe 6, and the connecting rod pin 61 passes through the side wall of the first connecting pipe 6 and abuts against the connecting rod 5.
[0020] As described above, the connecting rod pin 61 allows the connecting rod 5 to be inserted into the first connecting tube 6 at an adjustable length, and facilitates disassembly.
[0021] Furthermore, in the above-mentioned agricultural railcar track structure, two connecting rod pins 61 are threadedly connected to the side wall of the first connecting pipe 6.
[0022] As described above, the two connecting rod pins 61 make the connecting rod 5 more securely fixed.
[0023] Furthermore, in the above-mentioned agricultural railcar track structure, the edge of the connecting plate 4 is provided with ground anchor fixing holes 9 and ground anchor fixing pins 10. One end of the ground anchor is inserted into the ground anchor fixing hole 9, and the other end extends into the ground. The ground anchor fixing pin 10 is threadedly connected to the side wall of the ground anchor fixing hole 9, and the ground anchor fixing pin 10 passes through the side wall of the ground anchor fixing hole 9 and abuts against the ground anchor.
[0024] As described above, the ground anchor fixing pin 10 can adjust and tighten the connection between the ground anchor and the ground anchor fixing hole 9, preventing loosening during use, improving the stability and safety of the support structure, and making it convenient to connect and disassemble the ground anchor and the connecting plate 4.
[0025] Furthermore, in the above-mentioned agricultural railcar track structure, the length of the second pin hole 32 is 1.01-1.1 times the length of the connecting sleeve 2 inserted into the first guide rail 1.
[0026] As described above, this length ratio ensures that the connecting sleeve 2 has enough room to move completely away from the first guide rail 1, achieving rapid separation and improving disassembly efficiency.
[0027] Furthermore, in the above-mentioned agricultural railcar track structure, the guide rail is a square tube, and the connecting sleeve 2 is a square steel tube (rectangular or polygonal are also acceptable).
[0028] As described above, the square tube structure can effectively prevent relative rotation between the guide rail and the connecting sleeve 2, improve the stability and load-bearing capacity of the track structure, and is particularly suitable for complex terrains such as mountains and hills.
[0029] Furthermore, in the above-mentioned agricultural railcar track structure, the surfaces of the guide rail and connecting sleeve 2 are coated with an anti-corrosion coating with a thickness of 50-80 μm. (The guide rail and connecting sleeve can be made of stainless steel.) As described above, anti-corrosion coatings can significantly improve the weather resistance and service life of track structures, and are particularly suitable for outdoor humid environments.
[0030] Example 1 Please see Figures 1 to 6This embodiment provides a track structure for an agricultural railcar, including a track body composed of multiple guide rails connected end-to-end. A first guide rail 1 and a second guide rail 3 are connected by a connecting sleeve 2. The connecting sleeve 2 is a square steel pipe, with both ends inserted into the square cavities of the first guide rail 1 and the second guide rail 3 respectively to prevent relative rotation. The first guide rail 1 has a first pin hole 12, through which a first pin 11 passes and one end of the connecting sleeve 2. The second guide rail 3 has a second pin hole 32, through which a second pin 31 passes and the other end of the connecting sleeve 2. The second pin hole 32 is an elongated through hole, its length being greater than the length of the connecting sleeve 2 inserted into the first guide rail 1.
[0031] The track body also includes a connecting plate 4, a connecting rod 5, and a horizontal connector; the first pin 11 is provided with a horizontal connector, and its end has a vertical first connecting pipe 6; the connecting plate 4 is fixed to the ground by a ground anchor, and the connecting plate 4 is provided with a vertical second connecting pipe 7. The two ends of the connecting rod 5 are respectively sleeved on the first connecting pipe 6 and the second connecting pipe 7 to realize the connection between the track and the ground.
[0032] Two first connecting pipes 6 can be provided, and two corresponding second connecting pipes 7 and connecting rods 5 are also provided to balance the supporting force. Two connecting rod pins 61 are threadedly connected to the side wall of the first connecting pipe 6 for fixing the connecting rods 5. The edge of the connecting plate 4 is provided with ground anchor fixing holes 9 and ground anchor fixing pins 10. After the ground anchor is inserted into the ground anchor fixing hole 9, it is tightened by the ground anchor fixing pins 10.
[0033] The use of the above-mentioned agricultural railcar track structure: During installation, align the first guide rail 1 and the second guide rail 3, insert the connecting sleeve 2, so that the first pin 11 passes through the first pin hole 12 and one end of the connecting sleeve 2, and the second pin 31 passes through the fixing hole 321 of the second pin hole 32 and the other end of the connecting sleeve 2, so that the first guide rail 1 and the second guide rail 3 are connected.
[0034] During installation of the support assembly, the connecting plate 4 is fixed to the ground using ground anchors, with the anchors buried 30-50 cm deep. Then, the connecting rod 5 is fitted onto the first connecting pipe 6 and the second connecting pipe 7. The height of the connecting rod 5 is adjusted by adjusting the connecting rod pin 61, and the connecting rod 5 is then fixed in place. For disassembly, starting from any section of the track, the second pin is loosened, allowing it to move along the elongated through-hole of the second pin hole 32. This causes the connecting sleeve 2 to retract towards the second guide rail 3 until the connecting sleeve 2 is completely detached from the first guide rail 1, thus separating the first guide rail 1 and the second guide rail 3. Simultaneously, the connecting rod pin 61 and the ground anchor fixing pin 10 are loosened, and the connecting rod and ground anchor are pulled out, achieving quick disassembly.
[0035] In summary, this invention, by designing the second pin hole on the second guide rail as an elongated shape, allows the second pin to slide along the hole during disassembly, causing the connecting sleeve to retract completely into the second guide rail. This enables the first and second guide rails to separate quickly at any point on the track, allowing disassembly from the middle of the track rather than just from both ends, greatly improving the disassembly efficiency of long-distance tracks. Simultaneously, by adding a connecting plate and forming a support assembly with ground anchors and connecting rods, the load is distributed through the connecting plate, significantly reducing the required embedment depth of a single ground anchor, making the installation and disassembly of the support structure more convenient. These two improvements work synergistically, addressing the two key aspects of track segment connection and ground support fixation, respectively, to achieve efficient and rapid assembly and disassembly of the entire track system. It is particularly suitable for the transfer and reuse of long-distance tracks and for track maintenance and replacement. The overall structure is simple and reliable, easy to operate, and significantly improves the practicality and economy of agricultural rail vehicles.

Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
