[0036] like Figure 1 and Figure 2 , which is a schematic diagram of the structure of a transport device, the transport device includes a trolley 10, a track 20 for the trolley to run, and a driving device 30.

[0037] Among them, the track 20 includes a main track 201 and two auxiliary tracks 202, and the two auxiliary tracks 202 are respectively arranged on both sides of the main track 201; the main track 201 is an I-type track, and the main wheels 1011 include two arranged side by side, and the two main wheels 1011 are respectively located in the concave tracks on both sides of the I-type track, and the height of the main track 201 is lower than the height of the auxiliary tracks 202 on both sides.

[0038] Specifically, Figure 3 , which is a schematic diagram of the structure of a part of the track, wherein the track 20 includes a main track 201 and two auxiliary tracks 202, and the main track 201 is an I-shaped track, and the I-shaped track is located between the two auxiliary tracks 202. It can be understood that the two auxiliary tracks 202 are respectively arranged on both sides of the I-shaped track. In the embodiment of the present application, the auxiliary tracks 202 are set to two, but it is not excluded that multiple auxiliary tracks 202 can also be set on both sides of the I-shaped track. For example, four auxiliary tracks 202 can be set, that is, two auxiliary tracks 202 are set on each side of the I-shaped track. In other words, the number of the auxiliary tracks 202 can be set according to the actual working conditions.

[0039] The main track 201 cooperates with the main wheel 1011, and the main wheel 1011 includes two wheels arranged side by side. It can be understood that the two main wheels 1011 arranged side by side on the left and right are respectively located in the concave wheels on both sides of the I-shaped track and cooperate with the main track 201.

[0040] In the embodiment of the present application, the height of the main track 201 is lower than the height of the auxiliary tracks 202 on both sides. The height difference between the main track 201 and the auxiliary tracks 202 can be determined according to the actual working conditions, and no specific description is given here. In the embodiment of the present application, the main track 201 and the two auxiliary tracks 202 are assembled and fixed by a U-shaped bracket 203. It can be understood that the two auxiliary tracks 202 are fixed at both ends of the U-shaped bracket 203, and the main track 201 is fixed at the central position of the U-shaped bracket 203. In addition, the number of the U-shaped brackets 203 can be set according to the actual working conditions.

[0041] The trolley 10 runs on the track 20 , and the structure of the trolley 10 will be described in detail below.

[0042] The trolley 10 includes a trolley base 101 and at least two support members 102, the support members 102 are fixed on the trolley base 101, and the support members 102 are arranged at intervals along the length direction of the track 20, the trolley base 101 is provided with a main wheel 1011 and auxiliary wheels 1012 respectively arranged on both sides of the main wheel 1011, the main wheel 1011 cooperates with the main track 201, and the two auxiliary wheels 1012 cooperate with the two auxiliary tracks 202 respectively.

[0043] like Figure 4As shown, it is a schematic diagram of the partial structure of the trolley, and the trolley 10 is composed of a trolley base 101 and a support member 102, and the support member 102 is fixed on the trolley base 101. The number of the support members 102 is at least two, which can be understood as the number of the support members 102 is greater than or equal to two, and the number of the support members 102 can be set according to the specific working conditions. For example, the number of the support members 102 can be set according to the structure of the transported workpiece. When the transported workpiece is a long strip structure, such as a vehicle longitudinal beam, the number of the support members 102 can be greater than two. In other words, the number of the support members 102 can be adjusted according to the structure of the transported workpiece.

[0044] In the embodiment of the present application, three support members 102 are provided on the trolley base 101, and each of the support members 102 is arranged at intervals on the trolley base 101, specifically, they are arranged at intervals along the length direction of the track 20. The intervals between adjacent support members 102 can be the same distance or different distances, and the distance requirements between adjacent support members 102 can be determined according to specific working conditions, which will not be described in detail here.

[0045] The trolley base 101 includes: a first connecting member 1013, a second connecting member 1014 and a third connecting member 1015. The second connecting member 1014 is fixed to the first connecting member 1013 and is perpendicular to the first connecting member 1013. The third connecting member 1015 is located below the first connecting member 1013 and is parallel to the first connecting member 1013.

[0046] Among them, Figure 4 As shown, the first connecting member 1013 is in the shape of an elongated strip, the first connecting member 1013 is parallel to the length direction of the guide rail 20, and each of the supporting members 102 is fixedly arranged on the first connecting member 1013 at intervals. It can be understood that the first connecting member 1013 is parallel to the length direction of the track 20, and each of the supporting members 102 is fixedly arranged on the first connecting member 1013 at intervals, that is, each of the supporting members 102 is fixed above the first connecting member 1013, and each of the supporting members 102 is connected by the first connecting member 1013. In the embodiment of the present application, the first connecting member 1013 can be a long strip rod, but it is not excluded that the first connecting member 1013 can also be other structures.

[0047] The second connecting member 1014 is in a long strip shape, the second connecting member 1014 is perpendicular to the first connecting member 1013 , and the two auxiliary wheels 1012 are respectively installed at two ends of the second connecting member 1014 .

[0048] Specifically, when the support member 102 is fixed on the first connection 1013, a second connection member 1014 is provided between adjacent support members 102, that is, the second connection member 1014 is fixed above the first connection member 1013. The distance between the second connection member 1014 and the adjacent support member 102 can be equal or unequal, and the distance between the second connection member 1014 and the adjacent support member 102 can be selected according to the actual working conditions. Moreover, the length of the second connection member 1014 is determined by the width between the two auxiliary rails 202, that is, the length of the second connection member 1014 can just match the width between the two auxiliary rails 202. Auxiliary wheels 1012 are respectively installed at both ends of the second connection member 1014, that is, when the two auxiliary wheels 1012 are respectively installed at the two ends of the second connection member 1014, the length of the second connection member 1014 matches the distance between the two auxiliary rails 202, so that the two auxiliary wheels 1012 run on the two auxiliary rails 202. In the embodiment of the present application, the second connecting member 1014 is a long strip structure, but it is not excluded that the second connecting member 1014 can also be other structures. For example, the second connecting member 1014 can be a long strip concave structure as shown.

[0049] The third connecting member 1015 is in the shape of a long strip, and is fixedly connected below the first connecting member. The third connecting member 1015 is used to connect a plurality of the trolleys.

[0050] Specifically, the third connecting member 1015 is fixed below the first connecting member 1013, that is, below the first connecting member 1013, and the third connecting member 1015 is fixedly connected at a certain distance in the vertical direction. It should be noted that the certain distance in the vertical direction between the first connecting member 1013 and the third connecting member 1015 can increase the height of the entire trolley base. The distance in the vertical direction between the first connecting member 1013 and the third connecting member 1015 can be determined according to the specific working conditions, as long as the first connecting member 1013 and the third connecting member 1015 have a certain distance in the vertical direction. In the embodiment of the present application, the third connecting member 1015 is a long strip structure, but it is not excluded that the third connecting member 1015 can also be other structures. The width of the third connecting member 1015 is smaller than the width of the first connecting member 1013 , but the width of the third connecting member 1015 may also be equal to the width of the first connecting member 1013 , or the width of the third connecting member 1015 may also be greater than the width of the first connecting member 1013 .

[0051] like Figure 5As shown, a plurality of the trolleys 10 can be connected together through the third connecting member 1015. It can be understood that when a plurality of trolleys 10 need to be connected together, the third connecting members 1015 under each trolley base 101 can be connected.

[0052] The end portion 1015 - 1 of the third connecting member is L-shaped, and is used to connect the adjacent trolleys 10 by passing the fastener 1017 through the end portions 1015 - 1 of the third connecting member of two adjacent trolleys 10 .

[0053] Specifically, Figure 4 and Figure 5 As shown, the ends of the front and rear ends of the third connecting member 1015 are inverted L-shaped structures, and a through hole 1015-2 is provided on the inverted L-shape. When two adjacent trolleys 10 need to be connected, the inverted L-shaped structures of the third connecting member 1015 below the two adjacent trolleys 10 can be matched, that is, the through holes 1015-2 on the inverted L-shapes of the adjacent ends 1015-1 of the third connecting members are aligned up and down, and the fastener 1017 is passed through the through holes 1015-2 aligned with the adjacent ends 1015-1 of the third connecting members, so as to connect the adjacent trolleys 10.

[0054] Among them, the base of the trolley 10 also includes a main wheel mounting member 1016, and the main wheel mounting member 1016 is fixed below the third connecting member 1015; the main wheel 1011 is installed on the main wheel mounting member 1016, and the fastener 1017 is fixed on the main wheel mounting member 1016.

[0055] Specifically, Figure 4 As shown, the main wheel mounting member 1016 is provided with a connecting hole, and when the fastener 1017 passes through the through hole 1015-2 of the end portion 1015-1 of the third connecting member, it is connected with the connecting hole on the main wheel mounting member 1016 to fix the main wheel mounting member 1016 below the third connecting member 1015. In other words, the main wheel mounting member 1016 is fixed below the third connecting member 1015 by the fastener 1017.

[0056] The main wheel mounting member 1016 is used to mount the main wheel 1011. Specifically, the main wheel mounting member 1016 is composed of a left vertical plate, a right vertical plate, and a horizontal plate connecting the left and right vertical plates. The horizontal plate is located above the left and right vertical plates and connects the left and right vertical plates. The left and right vertical plates have the same structure. The connecting hole is located in the center of the horizontal plate, which is convenient for fixing the main wheel mounting member 1016 below the third connecting member 1015 through the fastener 1017. The two main wheels 1011 are installed on the inner sides of the left and right vertical plates. When the trolley 10 runs on the track 20, the two main wheels 1011 on the main wheel mounting member 1016 are respectively located in the concave tracks on both sides of the I-shaped track to cooperate with the I-shaped track to run.

The driving device 30 is installed at the side position of the length direction of the main track 201, that is, the first driving wheel 302 and the driving motor 301 are installed on the same side of the main track 201, and the second driving wheel 303 is installed on the opposite side of the first driving wheel 302, that is, opposite to the first driving wheel 302. When the driving motor 301 is started, the driving motor 301 drives the first driving wheel 302 to rotate, and the first driving wheel 302 drives the second driving wheel 303, and the third connecting member 1015 between the first driving wheel 302 and the second driving wheel 303 generates friction with the second driving wheel 303 to drive the trolley 10 to run on the track 20. In the embodiment of the present application, the diameter of the first driving wheel 302 is greater than the diameter of the second driving wheel 303 , but other structures are not excluded. For example, the diameter of the first driving wheel 302 is equal to the diameter of the second driving wheel 303 .

[0059] Wherein, the support member 102 includes a placing portion 1021, the placing portion 1021 is used to place and convey the workpiece, and the placing portion 1021 is fixed to the trolley base 101 through a connecting portion 1022; the connecting portion 1022 includes a vertical connecting rod 1022-1 and a limiting rod 1022-2, one end 1022-1 of the vertical connecting rod is fixed to the placing portion 1021, and the other end is fixed to the trolley base 101; one end of the limiting rod 1022-2 is fixed to the placing portion 1021, and the other end is fixed to the vertical connecting rod 1022-1, and is inclined to the vertical connecting rod 1022-1 to limit the swing of the placing portion 1021.

[0060] Specifically, Figure 4 As shown, the support member 102 includes the placement portion 1021 and the connection portion 1022, and the placement portion 1021 is used to place the transport workpiece. In the embodiment of the present application, the transport workpiece can be a vehicle longitudinal beam, that is, the longitudinal beam is placed on the placement portion 1021, and the longitudinal beam is transported to the destination by the trolley 10. The mounting portion 1021 can be a long condition structure or other structures. For example, the mounting portion 1021 can be a flat plate structure. It can be understood that the structure of the mounting portion 1021 can be determined according to the structure of the transport workpiece.

[0062] Specifically, the connecting portion 1022 includes a vertical connecting rod 1022-1 and a limiting rod 1022-2. In the embodiment of the present application, there are two limiting rods 1022-2, that is, two limiting rods 1022-2, which are respectively connected to the left and right sides of the vertical connecting rod 1022-1.
