Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 4 As shown, this utility model provides a material frame 1 transportation system for transporting material frames 1, which are used to collect material heads cut by a shearing machine. The material frame 1 transportation system includes a track and a transportation vehicle group with multiple transportation trolleys 3 connected in series along the longitudinal extension direction of the track. The track includes two parallel and spaced steel rails 2. The transportation vehicle group straddles the two steel rails 2. Each transportation trolley 3 carries a material frame 1. Power units 4 are provided on the transportation trolleys 3 at both ends to meet the bidirectional operation requirements of the transportation vehicle group. The transportation trolley 3 includes a base 31 and wheels 32 connected to the base 31. The transportation trolley 3 is slidably connected to the track through the wheels 32. The base 31 is a frame hollow structure with a preset height and has a bearing surface adapted to the bottom surface of the material frame 1. The transportation vehicle group can move relative to the track along the longitudinal extension direction of the track under the drive of the power unit 4, so that the material frames 1 carried on each transportation trolley 3 can switch to the work position for receiving material heads.

[0032] The material frame 1 transport system provided by this utility model has a transport trolley 3 that can just carry one material frame 1. By setting the base 31 of the transport trolley 3 as a frame hollow structure with a preset height, the overall deformation of the base 31 is reduced when the transport trolley 3 carries the material frame 1 containing high-temperature material heads. This ensures a safe distance between the wheels 32 and the material frame 1, and guarantees that the gap between each wheel 32 of the transport trolley 3 and the track is no more than 0.05mm. This ensures that each wheel 32 of the transport trolley 3 always maintains stable contact with the track, thereby meeting the requirements for switching workstations of the material frame 1 and the transport capacity requirements of the material frame 1 transport system.

[0033] Among them, such as Figure 1 and Figure 3 As shown, the bottom of the material frame 1 is equipped with support legs to increase the safety distance between the wheels 32 and the material frame 1, and to facilitate the assembly and disassembly of the material frame 1 from the transport trolley 3 using a forklift.

Preferably, the preset height of the base 31 is between 600 mm and 700 mm, so that the material frame 1 transportation system has a smaller space size.

[0036] According to a preferred embodiment of the present application, a limiting structure is arranged on the base 31, and the limiting structure is used to maintain the relative position of the material frame 1 and the bearing surface. By arranging the limiting structure, the movement of the material frame 1 relative to the transportation trolley 3 during the material frame 1 position switching process of the moving transportation trolley 3 is prevented, so that the positioning of the material frame 1 relative to the transportation trolley 3 is not inaccurate.

[0037] According to a preferred embodiment of the present application, as shown in Figure 1 The limiting structure includes clamping seats 33 arranged at the corners of the base 31. Specifically, the upper surface of the clamping seat 33 is higher than the supporting leg of the material frame 1, so as to effectively limit the relative position of the material frame 1 on the transportation trolley 3.

[0038] According to a preferred embodiment of the present application, the material frame 1 transportation system further comprises a connecting assembly 5, and at least one connecting assembly 5 is connected between adjacent two transportation trolleys 3. Specifically, as shown in Figure 2 When only one connecting assembly 5 is connected between the adjacent two transportation trolleys 3, the connecting assembly 5 is connected to the middle part of the transportation trolley 3 facing the center of the track. When multiple connecting assemblies 5 are connected between the adjacent two transportation trolleys 3, the multiple connecting assemblies 5 are arranged in a spaced manner along a direction perpendicular to the longitudinal extension direction of the track.

[0039] According to a preferred embodiment of the present application, two connecting assemblies 5 are connected between the adjacent two transportation trolleys 3, and the two connecting assemblies 5 are connected side by side to the three equal division points of the transportation trolley 3 along a direction perpendicular to the longitudinal extension direction of the track. In this way, the overall structural stability of the material frame 1 transportation system is considered.

[0040] According to a preferred embodiment of the present application, as shown in Figure 4As shown, the connecting assembly 5 comprises a connecting frame 51 and a connecting pin shaft 52, the connecting frame 51 is in U shape, the connecting frames 51 which are open to each other and partially staggered in the direction of gravity are connected to the sides of the adjacent two transport trolleys 3, and the connecting frames 51 connected to the adjacent two transport trolleys 3 are connected through the connecting pin shaft 52.

[0041] According to a preferred embodiment of the utility model, in order to ensure interchangeability and connection fastening, the connecting frame 51 is fixedly connected to the base 31 of the transport trolley 3 through bolts and compression nuts.

[0042] Based on the above description, the material frame 1 transport system provided by the utility model embodiment has the following beneficial effects:

[0043] The material frame 1 transport system provided by the utility model embodiment can just bear one material frame 1, and the base 31 of the transport trolley 3 is set as a frame hollow structure with a preset height, so as to reduce the overall deformation amount of the base 31 of the transport trolley 3 when bearing the material frame 1 loaded with the high-temperature material head, make the safe distance between the wheel 32 and the material frame 1, ensure that the gap between each wheel 32 of the transport trolley 3 and the track is not greater than 0.05mm, and make each wheel 32 of the transport trolley 3 always keep stable contact with the track, so as to meet the material frame 1 station switching requirement and the transport capacity requirement of the material frame 1 transport system; and the limiting structure is set, so as to prevent the material frame 1 from moving relative to the transport trolley 3 during the material frame 1 station switching process of the moving transport trolley 3, and cause the inaccurate positioning of the material frame 1 relative to the transport trolley 3.
