For example, the seedling trays are transported from the cultivation room to the seedling field by a transport cart, and then manually moved from the edge of the field to the seedling field for hydroponic growth. This transportation mode is labor-intensive and requires workers to walk back and forth between the field and the seedling field. Not only is the work efficiency low, but the operating cost is also high. At the same time, the manual transportation process is likely to cause damage to the seedlings, affecting their growth.

[0032] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0033] The terms such as "upper", "lower", "left", "right", and "middle" cited in this application are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0034] The terms "installed", "set", "provided with", and "connected" referred to herein should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] Example 1

[0036] like Figure 1 and Figure 2 As shown, a track frame provided in this embodiment is used in the overhead crane device of the plate-staggering machine, and the track frame is used to support the plate-staggering device in the overhead crane device. The track frame usually spans above the field where the plate is to be staggered, and the plate-staggering device moves on the track frame to perform the staggering. Usually, the track frame needs to be set to a certain length, so that the plate-staggering device can stagger in a larger field area during one operation along the track frame, thereby improving the working efficiency. However, in this case, if Figure 3 As shown, when the track frame is subjected to the gravity of the swing plate device, it is bound to bend downward, especially the middle part of the track frame, which will sink due to gravity, causing the track frame to sink a certain amount of height h relative to the horizontal section. The greater the gravity or the longer the track frame, the greater the sinking height h. The side of the track frame close to the bottom is subjected to greater tension. After long-term operation, it is easy to break, especially at the head and tail connection of adjacent track frame monomers, which is not conducive to the long-term use of the track frame.

[0037] In order to improve the situation that the track frame bends downward under the gravity of the swing plate device, this embodiment provides a track frame, including a plurality of track frame monomers, and adjacent track frame monomers are connected end to end. Figure 4 As shown, a clamping block is arranged between adjacent track frame monomers, and the clamping block enables the track frame to form an arched structure protruding upward. In this embodiment, the "upward" described is in the direction opposite to the direction of gravity, and the "downward" described is in the direction in the same direction as the direction of gravity. The track frame only needs to form a small-amplitude arched structure protruding upward, and the arched structure can resist the gravity borne on the track frame, reduce the sinking of the middle part of the track frame, and thus extend the service life of the track frame.

[0038] For the convenience of description, the side of the track frame unit close to the upper side is the track frame unit upper side, and the side of the track frame unit close to the lower side is the track frame unit lower side.

[0039] Recombination Figure 1 and Figure 2As shown, the cross section of the track frame in this embodiment can be square or triangular. When it is square, the track frame unit is a square frame 1, the upper side of the track frame unit is a square frame upper side 11, and the lower side of the track frame unit is a square frame lower side 12; when it is triangular, the track frame unit is a tripod 2, the upper side of the track frame unit is a tripod upper side 21, and the lower side of the track frame unit is a tripod lower side 22.

[0040] like Figure 5 and Figure 6 As shown, in this embodiment, the track frame monomer is a square frame 1 as an example for detailed description. When the track frame monomer is a tripod 2, its setting is consistent with the setting of the track frame monomer as the square frame 1.

[0041] The clamp block in this embodiment is a wedge block 3, and the clamp block is arranged close to the upper side of the track frame unit, and the clamp block does not exceed the upper side of the track frame unit. In some cases, other running components are arranged on the track frame, and the clamp block does not exceed the upper side of the track frame unit, which can avoid interference between the clamp block and other components.

[0042] like Figure 6 , Figure 7 and Figure 8 As shown, the wedge block 3 includes a wedge plate 31, which is inserted between the upper sides 11 of the adjacent square frames, so that a certain gap is opened between the upper sides 11 of the adjacent square frames, so that the track frame as a whole forms an arched structure facing upward. Specifically, the two ends of the wedge plate 31 are respectively a wedge plate outer end 311 and a wedge plate insertion end 312, and the wedge plate insertion end 312 is inserted between the upper sides 11 of the adjacent square frames, and the wedge plate outer end 311 does not exceed the side of the upper sides 11 of the square frames.

[0043] The wedge block 3 also includes a connecting plate 32, one side of the connecting plate 32 is connected to the wedge plate 31, and both ends of the connecting plate 32 are also connected to the adjacent square frame 1, so that the wedge block 3 is fixedly connected to the track frame.

[0044] In some cases, the wedge plate 31 is a smaller square. In this case, the thickness of the outer end 311 of the wedge plate is consistent with the thickness of the insertion end 312 of the wedge plate. A certain gap can be opened between the upper sides 11 of adjacent square frames, so that the track frame forms an arched structure.

[0045] However, in this embodiment, in order to increase the contact area between adjacent square frames 1 and the wedge plates 31 so that the wedge plates 31 can withstand a larger extrusion force, the wedge plates 31 are made of larger blocks, and the thickness of the outer ends 311 of the wedge plates is greater than the thickness of the insertion ends 312 of the wedge plates, so that the wedge plates 31 and the square frames 1 have the largest contact area on the sides that contact each other.

[0046] The connecting plate 32 is provided with an elongated hole, and the wedge block 3 is fixed to the adjacent square frame 1 by passing a bolt through the elongated hole. The elongated hole enables the wedge block 3 to move between the adjacent square frames 1, thereby adjusting the position of the wedge plate 31. By adjusting the position of the wedge plate 31, the degree of curvature in the arch structure of the track frame can be adjusted, so that the track frame can adapt to different load-bearing forces.

[0047] Example 2

[0048] This embodiment provides another clamping block structure. The track frame in this embodiment is consistent with that in Embodiment 1, except for the clamping block structure.

[0049] The clamping block in this embodiment is integrally connected to the track frame unit, and the track frame unit is still described by taking the square frame 1 as an example. At the side where adjacent square frames 1 are connected to each other, a clamping block is protruded near the upper side 11 of one of the square frames 1, and the square frames 1 are connected to each other so that the other end of the clamping block is placed on the next square frame 1, so that the track frame forms an arched structure.

[0050] By adopting the clamp block arrangement method in this embodiment, there is no need to connect the clamp block to the square frame 1 by bolts, thereby improving the efficiency of forming the track frame structure.

[0051] Example 3

[0052] This embodiment provides a track frame, and the structure of the track frame is consistent with that in Embodiment 1 or Embodiment 2. However, in this embodiment, in order to fix adjacent track frame monomers, in this embodiment, adjacent track frame monomers are further connected by a connecting assembly 4.

[0053] like Fig. 9 As shown, the connection assembly 4 includes two connection round tubes 41 respectively arranged on adjacent track frame monomers, the connection round tubes 41 are arranged near the lower side of the track frame monomer, and the two connection round tubes 41 are connected by bolts. The bolts pass through the round holes in the two connection round tubes 41 to connect them, so that the adjacent track frame monomers are fixedly connected, making the overall structure of the track frame more stable.

[0054] Example 4

[0055] This embodiment provides a track frame, and the structure of the track frame is consistent with that in Embodiment 1 or Embodiment 2. As in Embodiment 3, in this embodiment, in order to fix adjacent track frame monomers, in this embodiment, adjacent track frame monomers are further connected by a connecting assembly 4.

[0056] However, in this embodiment, the connecting component 4 includes a side connecting plate, which is in the shape of a flat plate, and has through holes at both ends of the side connecting plate, so that one end of the connecting side plate is connected to an adjacent track frame monomer by passing bolts through the through holes, and the other end is also connected to another adjacent track frame monomer by passing bolts through the through holes.

[0057] Example 5

[0058] like Figure 1 As shown, in this embodiment, a crane device is provided, comprising a swing plate device and a track frame as described in any one of embodiments 1-4, and the swing plate device is arranged on the track frame. Since the track frame in this embodiment has an arched structure protruding upward, when the weight of the swing plate device is borne, the sinking of the middle part of the track frame is improved, thereby extending the service life of the track frame.

[0059] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
