[0035] The track transport frame of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being for the general understanding of those skilled in the art and is not intended to limit this utility model.

[0036] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0037] like Figure 1-3 As shown in the figure, this utility model embodiment proposes a track transport frame, including a main crossbeam 1, corner brackets 2, and track wheel assemblies 3; the main crossbeam 1 serves as the main load-bearing frame; the corner brackets 2 are installed on the top surface of the main crossbeam 1 and can reciprocate laterally along the length direction of the main crossbeam 1 under the drive of external force, and two corner brackets 2 are provided; the track wheel assemblies 3 are installed at the bottom of the main crossbeam for connecting to the track; there are two sets of track wheel assemblies 3, and the two sets of track wheel assemblies 3 are distributed at the bottom ends of the main crossbeam 1.

[0038] In this embodiment, since the corner bracket 2 can reciprocate laterally along the length of the main beam 1, the position of the corner bracket can be adjusted according to the specific box type when the rail transport frame is in use, so that the corner bracket 2 can be connected with the corner hole of the box to be transported. This effectively expands the range of box widths that the rail transport frame can adapt to and increases the utilization rate of the rail transport frame.

[0039] In the above embodiment, the corner bracket 2 includes a corner pin 21 and a movable base 22.

[0040] The corner pin 21 is mounted on the movable base 22 and is used to match the corner hole of the transferred part. Specifically, the corner pin 21 is set to be able to pass through the corner hole of the transferred part. During the transfer operation, the corner hole of the box to be transferred is aligned with the corner pin 21, and the box is lowered to complete the docking of the corner pin 21 with the corner hole of the box to be transferred.

[0041] To facilitate the connection between the corner pin 21 and the corner hole, the outer periphery of the end of the corner pin 21 is appropriately cut to form a chamfer structure. This allows the corner pin 21 to be inserted into the corner hole more conveniently and quickly when connecting it to the corner hole.

[0042] Furthermore, to enhance the stability between the rail transport frame and the box to be transferred, a through hole 211 is provided on the side wall of the corner pin 21. After the corner pin 21 and the corner hole of the box to be transferred are connected, a pin or bolt is passed through the through hole 211 to further reinforce the connection with the corner of the box.

[0043] The movable seat 22 is movably mounted on the main crossbeam 1. Specifically, the main crossbeam 1 has recessed grooves on both sides, the movable seat 22 covers the top surface of the main crossbeam 1, and both ends of the movable seat 22 extend along the sides of the main crossbeam 1 into the grooves. This ensures that after the movable seat 22 is mounted on the main crossbeam 1, its movement in all directions except along the length of the main crossbeam 1 is effectively restricted. That is, while ensuring effective connection between the movable seat 22 and the main crossbeam 1, the movable seat 22 can reciprocate laterally along the length of the main crossbeam 1 to adjust the position of the corner bracket 2.

[0044] Furthermore, the movable seat 22 is provided with a locking member 23. After the movable seat 22 is driven to move to the required position by applying force, the locking member 23 is used to lock the position of the movable seat 22 to ensure the stability of the corner bracket seat 2 after the position is adjusted.

[0045] Specifically, refer to Figure 4 The locking member 23 includes a fixing bolt 231, which is threaded through and installed on one end surface of the movable seat 22 located in the groove. By rotating the fixing bolt 231, the fixing bolt 231 is pressed against the top surface of the groove of the movable seat 22, thereby locking the position of the corner bracket 2.

[0046] Optionally, the locking element 23 may also include an elastic washer 232, which is sleeved on the fixing bolt 231 and located between the moving seat 22 and the bolt head of the fixing bolt 231, reducing the possibility of the fixing bolt 231 loosening due to vibration or other factors.

[0047] In the above implementation process, since the main crossbeam 1 has grooves on both sides, it can be made from commonly available I-beams by cutting, which simplifies the processing. Meanwhile, as the main load-bearing frame, the compressive strength of the main crossbeam 1 needs to be guaranteed. Therefore, multiple reinforcing ribs 11 are spaced apart within the grooves of the main crossbeam 1 to improve its compressive strength.

[0048] In the above embodiment, the track wheel assembly 3 includes a secondary crossbeam 31 and track wheels 32; the secondary crossbeam 31 is installed at the bottom of the main crossbeam 1, and the secondary crossbeam 31 and the main crossbeam 1 are arranged in a cross shape; the track wheels 32 are rotatably installed on the secondary crossbeam 31, and there are multiple track wheels 32, which are distributed at intervals along the length direction of the secondary crossbeam 31 to provide multi-point support for the track transport frame.

[0049] In a preferred embodiment, the track transport frame further includes a pull rod 4, which includes a rod body 41 and a fixing pin 42 for fixing its end; the rod body 41 is detachably connected to the main crossbeam via the fixing pin 42. The pull rod 4 facilitates the dragging of the track transport frame for transporting the boxes.

[0050] Specifically, at least one side of the main crossbeam 1 is equipped with a fixing plate 12, and the fixing plate 12 is provided with a fixing hole 121. The fixing hole 121 can be used to cooperate with the fixing pin 42 to realize the detachable connection between the end of the rod 41 and the main crossbeam 1. At the same time, the fixing hole 121 can also be used to connect other track transport frames to ensure the stable connection between track transport frames.

[0051] In the preferred embodiment described above, a fixing plate 12 is installed on at least one side of the main crossbeam 1. That is, the main crossbeam 1 may have a fixing plate 12 installed on only one side, or it may have fixing plates 12 installed on both sides. By installing fixing plates 12 on both sides of the main crossbeam 1, it is convenient for relevant personnel to use.

[0052] Furthermore, as one implementation scheme, a fixing plate 12 is installed on at least one side of the main crossbeam 1. During the box-pulling operation, the fixing pin 42 at one end of the rod 41 is engaged with the fixing hole 121 on the fixing plate 12 on one side of the crossbeam 1, and the other end of the rod 41 is connected to the corresponding power device. Under the drag of the power device, the track transport frame is driven to move, thereby realizing the box-pulling operation.

[0053] As another implementation, the main crossbeam 1 has two fixing plates 12 installed on at least one side. Correspondingly, fixing pins 42 are installed at both ends of the rod 41, and the distance between the fixing pins 42 at both ends of the rod 41 is consistent with the distance between the fixing holes 121 on the two fixing plates 12 on the same side, thus providing additional storage function for the pull-out rod 4.

[0054] Specifically, since the distance between the fixing pins 42 at both ends of the rod 41 is the same as the distance between the fixing holes 121 on the two fixing plates 12 on the same side, when the pull rod 4 is in an idle state, the fixing pins 42 at both ends of the rod 41 can be engaged with the fixing holes 121 on the two fixing plates 12 on the same side, so that both ends of the rod 41 are connected to the main crossbeam 1. In this way, the rod 41 is stably placed on one side of the main crossbeam 1, thus realizing the storage of the pull rod 4.

[0055] When the box-pulling rod 4 is needed, the fixing pin 42 at one end of the rod 41 is separated from the fixing hole 121 that it matches, and then the end is connected to the corresponding power device. Under the drag of the power device, the track transport frame is driven to move, so as to realize the box-pulling operation.

[0056] In summary, compared with the prior art, this utility model has at least the following advantages:

[0057] The corner brackets of the rail transport frame provided by this utility model can move back and forth along the length of the main crossbeam. This allows the position of the corner brackets to be adjusted according to the specific box type during use, effectively expanding the range of box widths that the rail transport frame can adapt to and increasing the utilization rate of the rail transport frame.

[0058] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
