[0041] Preferably, the base 100 further comprises a mounting beam 140 connected between the two first side beams 110, the mounting beam 140 is parallel to the second side beam 120, the mounting beam 140 is suitable for separating the base 100 into a first bearing area 150 and a second bearing area 160 distributed along the first horizontal direction, the first bearing area 150 and the second bearing area 160 are suitable for accommodating a single axle respectively, and the mounting frame 330 is arranged on the mounting beam 140. The above structure enables a single transport frame to accommodate two axles at the same time, and the two axles can be reliably separated under the action of the mounting frame 330, and the reliability after mounting is good.

[0042] In the embodiment, the base 100 is specifically in a rectangular frame structure, the length of the first side beam 110 is greater than the length of the second side beam 120, and the mounting beam 140 is connected to the middle region of the first side beam 110 in the first horizontal direction, so that the mounting frame 330 mounted on the mounting beam 140 can uniformly separate the first bearing area 150 and the second bearing area 160. The length of the first side beam 110 and the second side beam 120 can be adaptively set according to the actual need of the transported axle, which is not limited in the utility model.

[0043] Further, the first fixing piece 310 is arranged on both sides of the mounting beam 140 in the first horizontal direction, and at least one first fixing piece 310 is arranged on each side in the second horizontal direction. In the embodiment, the number of the first fixing piece 310 on each side is specifically two, and the first fixing piece 310 is located at both ends of the mounting beam 140, so as to correspond to the first bearing area 150 and the second bearing area 160 one by one.

[0044] The mounting frame 330 comprises a column 331 and a crossbeam 332, the column 331 is arranged on the mounting beam 140 in the vertical direction and is preferably located at the middle of the mounting beam 140, and the crossbeam 332 is arranged at the top of the column 331 in the first horizontal direction and is located at the first bearing area 150 and the second bearing area 160 respectively, the second fixing member 320 is two in number and is arranged at the two ends of the crossbeam 332 respectively to correspond to the first bearing area 150 and the second bearing area 160 respectively. The second fixing member 320 is specifically a long strip plate structure, the second fixing member 320 extends along the second horizontal direction, and the second fixing hole 321 is arranged at least one in number and is arranged at intervals along the extension direction of the second fixing member 320. In the embodiment, the number of the second fixing hole 321 of each second fixing member 320 is two and is arranged at the two ends of the second fixing member 320 respectively.

[0045] Further, the first fixing member 310 and the second fixing member 320 corresponding to the first bearing area 150 are located at the same side, the first fixing member 310 and the second fixing member 320 corresponding to the second bearing area 160 are located at the same side, and the first fixing hole 311 and the second fixing hole 321 are both formed through in the first horizontal direction, so that the transport frame can be locked or unlocked with the hole position of one side of the axle, facilitating disassembly and assembly. Preferably, the first fixing hole 311 and / or the second fixing hole 321 is a strip-shaped hole, and the length direction is parallel to the second horizontal direction. Since the axle is arranged on the base 100, it can be blocked and positioned by the supporting column 200 and the mounting frame 330 in the first horizontal direction, but there is no blockage in the second horizontal direction, and the position accuracy is poor. By using a strip-shaped hole, when the axle is offset in the second horizontal direction, the hole position can still correspond to the first fixing hole 311 and / or the second fixing hole 321.

[0046] Further, in an embodiment, the first fixing member 310 is welded with the crossbeam 332, and the second fixing member 320 is welded with the mounting frame 330. However, when other models of axles are replaced, the hole position is not easy to correspond to the first fixing hole 311 and the second fixing hole 321. As a preferred embodiment, the first fixing member 310 is detachably connected with the mounting beam 140, and / or the second fixing member 320 is detachably connected with the mounting frame 330, so that when different models of axles need to be adapted, only the corresponding first fixing member 310 and the second fixing member 320 need to be replaced. Indeed, in other embodiments, a position adjusting structure can be arranged between the first fixing member 310 and the mounting beam 140, and / or a position adjusting structure can be arranged between the second fixing member 320 and the mounting frame 330, so as to adjust the position according to different models of axles. The position adjusting structure can be realized by using a sliding rail structure, a threaded member cooperating with an adjusting hole structure, etc., which is a structure known in the art, and will not be described herein.

[0047] Furthermore, the base 100 is provided with a first support 400 corresponding to each support column 200. The support column 200 is rotatably mounted on the first support 400 and is adapted to rotate to an unfolded or folded state. When the support column 200 is in the unfolded state, it stands upright on the base 100 to support the transport frame located above. When the support column 200 is folded, it is folded to the top side of the base 100. And / or, the base 100 is provided with a second support 500, and the mounting frame 330 is rotatably mounted on the second support 500. The second support 500 is adapted to rotate to an unfolded or folded state. When the mounting frame 330 is in the unfolded state, it stands upright on the base 100 to fix the axle. When the mounting frame 330 is in the folded state, it is folded to the top side of the base 100. By adopting the above structure, when the transport rack is in an unused state, the support column 200 and / or mounting bracket 330 can be folded onto the base 100, reducing the space occupied by the transport rack in an unused state and facilitating the storage of the transport rack in a limited space.

[0048] Specifically, refer to Figure 2 and Figure 3 As shown, a first support 400 is recessed inward from its side to form a first mounting groove 410. The first mounting groove 410 extends vertically and extends to the top of the first support 400. The support column 200 is adapted to be vertically inserted into the first mounting groove 410 from the top of the first support 400. A guide structure is provided between the first support 400 and the support column 200. The support column 200 is adapted to be translated under the guidance of the guide structure to a locking position near the bottom of the first mounting groove 410 or an unlocking position away from the bottom of the first mounting groove 410. When the support column 200 is in the locking position, the support column 200 is adapted to remain in an upright state. When the support column 200 is in the unlocking position, the support column 200 is adapted to turn from the opening of the first mounting groove 410 to the base 100. In this embodiment, the bottom of the first mounting groove 410 specifically refers to the end face of the first mounting groove 410 located at the recessed end, and the opening of the first mounting groove 410 is an open opening located on the side of the first support 400 and opposite to the bottom of the groove.

[0049] The guide structure is located near the lower end of the support column 200. The guide structure comprises a connecting hole 420, a first guide portion 210 and a connecting member 610. The connecting hole 420 is formed through at least one side wall of the first mounting groove 410 in the horizontal direction. The first guide portion 210 is recessed inward from the side of the support column 200 and corresponds to the connecting hole 420. The connecting member 610 is fixedly inserted into the connecting hole 420, at least partially disposed in the first guide portion 210, and can translate along the first guide portion 210 and rotate relative to the first guide portion 210. In this embodiment, the connecting hole 420 is formed through from one side wall to the other side wall of the first mounting groove 410 in the horizontal direction. The first guide portion 210 is an aperture structure formed through from one side to the other side of the support column 200. The connecting member 610 is adapted to pass out of the other end through the first guide portion 210 from one end of the connecting hole 420. The connecting member 610 can be a threaded member such as a screw or a bolt. The connecting member 610 is threadedly connected with the connecting hole 420. When the connecting member 610 is a bolt, the cap portion of the connecting member 610 is located outside one end of the connecting hole 420. The head portion of the connecting member 610 extends out of the other end and is threadedly connected with a locking nut 620. By tightening the locking nut 620, the first support 400 is tightly pressed between the cap portion of the connecting member 610 and the locking nut 620, thereby achieving fastening of the connecting member 610 with the first support 400. When the connecting member 610 is a screw, one end of the connecting member 610 is located outside one end of the connecting hole 420, and the other end of the connecting member 610 is located outside the other end of the connecting hole 420. Both ends of the connecting member 610 are threadedly connected with the locking nuts 620. The first support 400 is tightly pressed between the locking nuts 620 at both ends of the connecting member 610, thereby achieving fastening of the connecting member 610 with the first support 400.

[0050] Further, the first guide portion 210 comprises a horizontal segment 211 and a vertical segment 212. When the support column 200 is in the vertical state, the length direction of the horizontal segment 211 is parallel to the recess direction of the first mounting groove 410. The horizontal segment 211 has a first end 213 away from the groove bottom of the first mounting groove 410 and a second end 214 close to the groove bottom of the first mounting groove 410. The vertical segment 212 extends upward from the first end 213 in a direction perpendicular to the horizontal segment 211. The vertical segment 212 has a third end 215 away from the first end 213. The support column 200 is adapted to move along the horizontal segment 211 to a locked position or an unlocked position. The connecting member 610 is at the first end 213 in response to the movement of the support column 200 to the locked position, and is at the second end 214 in response to the movement of the support column 200 to the unlocked position. The support column 200 in the locked position is adapted to move downward along the vertical segment 212 under the action of gravity, so that the third end 215 moves toward the connecting member 610.

[0051] When it is needed to unfold the support column 200, the support column 200 is turned upward to the vertical state, then the support column 200 is moved along the horizontal section 211 toward the groove bottom of the first mounting groove 410, and when the connecting piece 610 is at the first end 213, the support column 200 is adapted to move downward along the vertical section 212 under the action of gravity to realize locking; when it is needed to fold the support column 200, the support column 200 is lifted upward along the vertical section 212 so that the connecting piece 610 is at the first end 213, then the support column 200 is moved along the horizontal section 211 so that the connecting piece 610 is at the second end 214, at this time the support column 200 can be folded on the base 100.

[0052] With the above structure, when the support column 200 is at the locking position, the support column 200 drives the connecting piece 610 to be in the vertical section 212 under the action of gravity, the connecting piece 610 can limit the support column 200 in the recess direction of the first mounting groove 410, so that the support column 200 at the locking position is not easy to move along the recess direction of the first mounting groove 410, when the support column 200 needs to be switched to the unlocking position, the support column 200 needs to be lifted upward first so that the connecting piece 610 is at the first end 213, and then the support column 200 is moved along the horizontal section 211 so that the connecting piece 610 is at the second end 214, thereby effectively improving the reliability of the support column 200 at the locking position and improving the supporting effect.

[0053] In addition, the first support 400 and the support column 200 are provided with a locking structure, the locking structure comprises a locking groove 430 and a locking block 220, the locking groove 430 is recessed inward from the top of the first support 400, the locking block 220 is protruded on the side surface of the support column 200 and corresponds to the locking groove 430, and the connecting piece 610 is clamped into the locking block 220 in response to the downward movement of the support column 200 along the vertical section 212, thereby further limiting the support column 200 and avoiding its rotation.

[0054] Further, the number of the first supports 400 is four, and they are respectively arranged at different corners of the base 100, so as to ensure the stacking support reliability, simplify the structure, and effectively limit the axle in the first horizontal direction with the mounting frame 330. Preferably, the rotation axis of the support column 200 is parallel to the second horizontal direction, the recess direction of the first mounting groove 410 is parallel to the first horizontal direction, and the groove openings of the first mounting grooves 410 on both sides of the first horizontal direction are arranged toward each other, so that two of the support columns 200 are adapted to be folded and supported on one long edge section of the base 100, that is, on one first side beam 110, and the other two support columns 200 are adapted to be folded and supported on the other long edge section of the base 100, that is, on the other first side beam 110, so as to facilitate the folding and unfolding operation of the workers.

[0055] Further, in an embodiment, the structure of the second support 500 can be the same as that of the first support 400, and a guide structure is arranged between the column 331 and the second support 500, so that the column 331 can rotate relative to the second support 500, which will not be described herein.

[0056] However, the mounting rack 330 is relatively cumbersome to fold and unfold by using the above structure, and since the mounting rack 330 is only used to fasten the axle, the support requirement is relatively low, and the state switching does not need to be designed as the structure of the state switching of the support column 200. As a preferred embodiment, referring to Figs. 5 and 6, the second support 500 is arranged on the second side beam 120, and the second support 500 is connected to the second side beam 120 by a connecting piece 610. Figure 4 and Figure 5 As shown in Figs. 5 and 6, the second support 500 is formed with a second mounting slot 510, the second mounting slot 510 is open on the top side and two opposite sides in the horizontal direction, the column 331 is adapted to be vertically inserted into the second mounting slot 510 from the top of the second support 500, and the connecting piece 610 is also fixed on the second support 500, and the specific mounting structure of the connecting piece 610 can refer to the connection structure of the first support 400 and the connecting piece 610. The side wall of the column 331 is recessed with a second guide portion 3311, the connecting piece 610 is at least partially arranged in the second guide portion 3311 and can translate along the second guide portion 3311 and rotate relative to the second guide portion 3311. In the embodiment, the second guide portion 3311 is a strip-shaped hole or a strip-shaped slot, the length direction of which is parallel to the vertical direction, and the column 331 can translate along the second guide portion 3311 relative to the second support 500. A locking structure is also arranged between the second support 500 and the column 331, and the column 331 is adapted to move downward under the action of gravity and make the locking structure in the rotating locking working state, so as to ensure that the column 331 remains in the vertical state.

[0057] In an embodiment, the rotation axis of the column 331 can be parallel to the second horizontal direction, however, since the cross beam 332 is arranged along the first horizontal direction, it protrudes relative to the column 331 in the first horizontal direction, and when the rotation axis of the column 331 is parallel to the second horizontal direction, there will be a large gap between the mounting rack 330 and the base 100 after the mounting rack 330 is folded, which is not conducive to reducing the occupied space. Preferably, in the embodiment, the rotation axis of the column 331 is parallel to the first horizontal direction, and the two sides of the second mounting slot 510 in the second horizontal direction are open, so as to improve the folding effect. The top of the mounting rack 330 in the folded state is located on the first side beam 110 or the mounting beam 140, which will not be limited herein, when the top of the mounting rack 330 is located on the first side beam 110, a certain gap needs to be left between the two support columns 200 folded on the first side beam 110 to avoid the mounting rack 330, and when the mounting rack 330 is supported on the mounting beam 140, the two support columns 200 do not need to leave a gap to avoid the mounting rack 330.

[0058] When it is needed to fold the column 331, the column 331 can be turned to the base 100 by lifting it upward along the second guide part 3311 and releasing the rotational locking of the locking structure, which is convenient to operate and does not need to move the column 331 horizontally. The second installation slot 510 is open on both sides in the horizontal direction compared with the first installation slot 410, and the column 331 is not blocked by the slot bottom, so that the column 331 can be optionally turned clockwise to one of the first side beams 110 or counterclockwise to the other first side beam 110 according to the actual needs of the operator, further facilitating the folding and unfolding of the operator.

[0059] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
