Description

Technical Field

[0001] The utility model relates to the technical field of tracks, in particular to a folding track structure. Background Art

[0002] Railcars are currently widely used on farms, mainly for transporting agricultural equipment and fruits and vegetables. As an essential module of railcars, the track presets the route of the railcar and determines the stability during driving. After the railcar completes its operation, the track actually hinders the farmers' other agricultural operations on the farm. For this reason, the existing track is set to be foldable and retractable. For example, the prior art invention patent CN118007477A discloses a lightweight, foldable, non-fixed flexible track. Adjacent tracks are connected by connecting columns and rotating columns, so that the adjacent tracks can be rotated more than 180 degrees in the forward and reverse directions, and the track can be folded after disassembly. However, when the track is unfolded, when the railcar presses down the connecting column and the rotating column, the tracks on both sides rotate toward the connecting column and the rotating column and sink, so that the track surface is not on the same horizontal plane, which easily causes the railcar to be bumpy and stuck in movement. Utility Model Content

[0003] The purpose of the utility model is to provide a folding track structure, which solves the problem in the prior art that the track connection is prone to sinking, resulting in unsmooth movement of the track vehicle, and makes the track less likely to sink when unfolded, thereby making the track vehicle move more smoothly.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a folding track structure, including a track assembly, the track assembly including at least two track segments arranged in the same direction, the track segments forming a track surface, and two adjacent track segments being rotatably connected by a connecting piece so that the track surfaces of the two adjacent track segments can be unfolded toward each other or folded in the opposite direction, and the track assembly is provided with a supporting piece for supporting the connecting piece to limit the track surfaces of the two adjacent track segments from sinking and rotating relative to the track segment when they are unfolded toward each other to be in the same plane.

[0005] After adopting the above technical solution, the utility model has the following advantages: the track surfaces of adjacent track sections can be unfolded toward each other or folded in opposite directions, realizing the bidirectional folding function of the folding track structure; secondly, the connector is provided with a support member, and the support member is designed to support the connector so that the connector will not sink; when the track section is unfolded, the connector is restricted from rotating relative to the track section, and the connectors at both ends of the track section are supported by the support member so that the track section will not sink either, thereby reducing the bumps and the risk of jamming caused by the uneven track during the travel of the rail vehicle, thereby making the rail vehicle move more smoothly.

[0006] Furthermore, the support member includes a vertical support portion and a horizontal support portion, and the horizontal support portion is provided with an avoidance opening for avoiding the track segment.

[0007] With the aforementioned technical solution, the horizontal support portion is provided with an avoidance opening, which means that the track segment will not be obstructed by the horizontal support portion when unfolding or folding, thus avoiding interference caused by the horizontal support portion, and allowing the track segments to be folded and stored parallel to each other, thereby allowing a larger horizontal support portion to be set. The larger the horizontal support portion, the more stable the support.

[0008] Furthermore, the track segment includes two straight rods arranged opposite to each other, and a cross rod arranged between the two straight rods. The straight rods constitute a track surface. The straight rods of two adjacent track segments are rotatably connected by a connecting piece, and the cross rod is used to support the straight rods.

[0009] By adopting the above-mentioned technical solution, the crossbars support the straight bars, so that the straight bars and connectors are all supported, and together they support the track, making the track system more stable when deployed and in use, especially maintaining a good balance on uneven ground.

[0010] Furthermore, when the track surfaces of two adjacent track segments are unfolded toward each other and are in the same plane, the bottom end of the cross bar and the bottom end of the support member are in the same plane.

[0011] By adopting the above-mentioned technical solution, the bottom end of the cross bar and the bottom end of the support member are at the same height in the same plane, so that the straight rod and the connecting member are supported at the same height, and the track surface is as completely in the same horizontal plane as possible after the track is unfolded. This helps the rail car to remain stable during driving and reduce bumps.

[0012] Furthermore, the track segment includes a connecting recess and a connecting protrusion, and the connecting member includes a connecting piece for connecting two adjacent track segments, and both ends of the connecting piece can be inserted into the connecting recess and rotatably connected to the track segment.

[0013] By adopting the above technical solution, the connecting piece can be easily inserted into the connecting recess, so that the connecting piece is hidden and installed, thereby avoiding rotation of the connecting piece due to external force, and further ensuring the stability of the track section when it is unfolded.

[0014] Furthermore, there are multiple connecting pieces, and the lengths of the multiple connecting pieces are different. One of the connecting pieces is selected to be connected between two adjacent track segments.

[0015] By adopting the above-mentioned technical solution, connecting plates of different lengths can adapt to the connection requirements between track segments of different spacings, so that the folding track structure can flexibly cope with track configurations of different sizes, and can also keep the track segments horizontal after folding for easy storage.

[0016] Furthermore, the end of the connecting piece and / or the connecting recess is provided with an avoidance surface.

[0017] With the aforementioned technical solution, the presence of the avoidance surface allows the track segment to have more room for movement when unfolding or folding, making it easier to unfold and fold.

[0018] Furthermore, the connecting piece is rotatably connected to the track segment via a rotating shaft.

[0019] By adopting the above-mentioned technical solution, the connecting piece can rotate freely through the shaft connection, so that the track segment can be more flexible when unfolding or folding.

[0020] Furthermore, the folding track structure also includes a binding strap, and the plurality of track segments can be fixed by the binding strap.

[0021] By adopting the above-mentioned technical solution, the straps can ensure that the track assembly remains stable in the folded state, making multiple track sections more compact and easy to carry. It can also minimize the accidental unfolding or loosening of the track assembly during transportation, reducing potential safety hazards. The straps can be adjusted according to actual needs to adapt to different track assemblies.

[0022] Furthermore, the folding track structure also includes a movable roller, which is detachably mounted on one of the track segments.

[0023] By adopting the above-mentioned technical solution, the setting of the movable rollers allows the entire folding track structure to be easily moved on the ground after being stored, reducing the burden of carrying the folding track structure. The movable rollers can be installed or removed according to actual needs to reduce the impact on the use of the folding track structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] like Figures 1 to 9 As shown, the present invention provides a foldable track structure, primarily installed in agricultural fields. A rail vehicle operates on the track to transport agricultural equipment and fruits and vegetables. The track assembly comprises a track assembly comprising at least two track segments 10 arranged in the same direction. The track segments 10 form a track surface 101. Adjacent track segments 10 are rotatably connected by a connector 110, allowing the track surfaces 101 of the two adjacent track segments 10 to unfold toward each other or fold in opposite directions, achieving bidirectional folding of the track structure. The track assembly is provided with a support member 120 for supporting the connecting member 110, so that the connecting member 110 will not sink, so as to limit the sinking of the connecting member 110 and the rotation relative to the track segment 10 when the track surfaces 101 of two adjacent track segments 10 are unfolded toward each other to be in the same plane, and limit the rotation of the connecting member 110 relative to the track segment 10. The connecting members 110 at both ends of the track segment 10 are supported by the support member 120, so that the track segment 10 will not sink. This reduces the bumps and the risk of jamming caused by the uneven track during the travel of the rail vehicle, thereby making the rail vehicle move more smoothly.

[0042] Specifically, the track segment 10 includes a connecting recess 103 and a connecting protrusion 104. The connecting piece 110 is used to connect the connecting pieces of two adjacent track segments 10. Both ends of the connecting piece can be inserted into the connecting recess 103 and rotatably connected to the track segment 10, so that the connecting piece forms a hidden installation to avoid the connecting piece from rotating due to external force, further ensuring the stability of the track segment 10 when it is unfolded.

[0043] In order to make the track easier to store after folding, multiple connecting plates are provided, and the lengths of the multiple connecting plates are different. One of the connecting plates is selected to connect between two adjacent track segments 10. Connecting plates of different lengths can adapt to the connection requirements between track segments 10 with different spacings, so that the folding track structure can flexibly cope with track configurations of different sizes, and can also keep the track segment 10 horizontal after folding for easy storage.

[0044] To facilitate the unfolding and folding of track segment 10, a clearance surface 111 is provided at the end of the connecting piece. This clearance surface 111 provides more room for movement when unfolding or folding the track segment 10, making it easier to unfold and fold. The clearance surface 111 is an inclined or curved surface extending from the center of the connecting piece end toward both sides, away from the track segment 10.

[0045] It is understandable that in other embodiments, the connecting recess 103 is provided with an escape surface 111. Of course, the escape surface 111 can also be provided at both the end of the connecting piece and the connecting recess 103.

[0046] The connecting piece is rotatably connected to the track segment 10 via the rotating shaft 112. The connecting piece can rotate freely via the rotating shaft 112, so that the track segment 10 can be more flexible when unfolding or folding.

[0047] The support member 120 includes a vertical support portion 121 and a horizontal support portion 122. The horizontal support portion 122 is provided with an avoidance opening 123 for avoiding the track segment 10. The avoidance opening 123 is located on the side close to the track segment 10, which means that the track segment 10 will not be hindered by the horizontal support portion 122 when unfolding or folding, avoiding interference caused by the horizontal support portion 122, so that the track segments 10 can be folded and stored parallel to each other, so that a larger horizontal support portion 122 can be set. The larger the horizontal support portion 122, the more stable the support.

[0048] In addition, the track segment 10 includes two straight rods 100 arranged opposite to each other, and a cross rod 102 arranged between the two straight rods 100. The straight rods 100 constitute a track surface 101. The straight rods 100 of two adjacent track segments 10 are rotatably connected by a connecting piece 110. The cross rod 102 is used to support the straight rods 100, so that the straight rods 100 and the connecting piece 110 are both supported and jointly support the track, so that the folding track structure is more stable when unfolded and used, especially on uneven ground. It can maintain good balance.

[0049] In order to improve the stability of the track segment 10, a plurality of cross bars 102 may be provided to form multiple supports for the straight bars 100 so that the track surface 101 is not prone to sinking.

[0050] In this embodiment, two adjacent track segments 10 are stored by sequentially folding in opposite directions and folding in the same direction. When folding in opposite directions, the horizontal support portion 122 is located between the two track segments 10, and a longer connecting piece can be used. When folding in the same direction, the horizontal support portion 122 is located outside the two track segments 10, and a shorter connecting piece can be used to reduce the distance between the track segments 10, thereby making the stored track assembly more compact and easier to carry. Accordingly, the track assembly can be provided with three, four, five, six, or other track segments 10.

[0051] It should be noted that, since the connection between the connecting piece and the straight rod 100 is easily damaged, the straight rod 100 may be provided with a detachable connecting head, and the connecting piece 132 may be rotatably connected to the connecting head via a rotating shaft.

[0052] Among them, when the track surfaces 101 of two adjacent track sections 10 are unfolded toward each other and are in the same plane, the bottom end of the cross bar 102 and the bottom end of the support member 120 are in the same plane, so that the straight rod 100 and the connecting member 110 are supported at the same height, and the track surfaces 101 are completely in the same horizontal plane after the track is unfolded. This helps the rail vehicle to maintain stability during driving and reduce bumps.

[0053] In order to facilitate the transportation of the track segments 10 after they are folded, the folding track structure also includes a strap 200. Multiple track segments 10 can be fixed by the strap 200. The strap 200 can surround the periphery of the multi-layer crossbars 102 from top to bottom, or surround the periphery of each layer of crossbars 102. The strap 200 can ensure that the track assembly remains stable in the folded state, making the multiple track segments 10 more compact and easy to carry. It can also minimize the accidental unfolding or loosening of the track assembly during transportation, reducing potential safety hazards. The strap 200 can be adjusted according to actual needs to adapt to different track assemblies.

[0054] Furthermore, the folding track structure also includes a movable roller 300, which can be detachably mounted on one of the track sections 10. The arrangement of the movable roller 300 allows the entire folding track structure to be easily moved on the ground after being stored, reducing the burden of carrying the folding track structure. The movable roller 300 can be installed or removed according to actual needs, reducing the impact on the use of the folding track structure. The movable roller 300 includes a support frame 310 and a universal wheel 320 provided on the support frame 310. The support frame 310 is provided with a groove 330 for inserting the crossbar 102 and a connecting switch for opening and closing the groove 330. The groove 330 can be conveniently opened or closed by the connecting switch, allowing the operator to easily install or remove the movable roller 300, which means that the movable roller 300 can be installed or removed according to actual needs, reducing the impact on the use of the track structure.

[0055] The connection switch includes a limit rod 340 that is rotatably connected to the opening of the groove 330 and a handle 350 fixedly connected to the limit rod 340. The groove 330 is provided with mounting holes on both sides. The limit rod 340 has a first position that closes the groove 330 and a second position that opens the groove 330. When the limit rod 340 is in the first position, the limit rod 340 is simultaneously inserted into the mounting holes on both sides of the groove 330. When the limit rod 340 is in the second position, the limit rod 340 is removed from at least one mounting hole on one side of the groove 330, allowing the crossbar 102 to be removed from the groove 330. The mounting holes can be threaded holes, and the limit rod 340 is threadedly connected to the mounting holes. The limit rod 340 can be driven to switch between the first position and the second position by rotating the handle 350. Of course, in other embodiments, the mounting holes and the limit rod 340 can also be plugged together, and the limit rod 340 can be driven to switch between the first position and the second position by pulling the handle 350.

[0056] It is understandable that in other embodiments, an avoidance gap may be provided between the end of the connecting piece and the connecting recess to facilitate the unfolding and folding of the track segment.

[0057] It is understandable that in other embodiments, the connecting piece may also be rotatably engaged with the connecting protrusion and the connecting hole.

[0058] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
