The drum reversing device 30 includes: frame 40, support 50, upset seat 60 and spacing portion. The roll stand 60 is used to mount the drum 20. The flipping base 60 is pivotally connected to the frame 50. The limiting part is arranged on the overturning seat 60 and used for limiting the pivoting of the overturning seat 60 relative to the bracket 50. The frame body 40 is arranged below the vehicle carrying platform 10, and the support 50 is connected with the frame body 40 and is positioned in the frame body 40. In this way, the roller 20 can be pivoted relative to the bracket 50 to be positioned below the vehicle platform 10 (in the stored state) by the arrangement of the turnover seat 60 and the bracket 50, so that the opening or closing of the turnover door is not influenced, and the roller 20 can not be pivoted relative to the bracket 50 and is kept positioned above the vehicle platform 10 (in the working state) by the structure of the limiting part. By the structure of the frame body 40, the turnover seat 60 and the bracket 50 can be integrally and directly installed at the target position of the vehicle-carrying platform 10.

The frame body 40 is provided with a clamping groove 41, the clamping groove 41 is arranged corresponding to the limiting part, and the clamping groove 41 and the limiting part are matched for limiting the pivoting of the overturning seat 60 relative to the bracket 50. In the present embodiment, the frame 40 is rectangular, but is not limited to rectangular, and may have other shapes having two sides symmetrically disposed.

The number of the brackets 50 is two, the two brackets 50 are respectively disposed on two opposite sides of the frame body 40, the tilting seat 60 is disposed between the two brackets 50, and two ends of the tilting seat 60 are respectively pivoted with the two brackets 50. Thus, by providing two brackets 50, the rotation of the roll-over stand 60 is more stabilized.

The roll-over stand 60 includes: side panels 61, a bottom panel 62 and a riser 63. One end of the side plate 61 is used for mounting the drum 20, and the other end of the side plate 61 is pivoted to the bracket 50 by a pivot shaft 70. The bottom plate 62 is connected with the side plate 61 and is located between the drum 20 and the bracket 50, a first included angle α is formed between the bottom plate 62 and the side plate 61, and the limiting part is arranged at one end of the bottom plate 62, which is far away from the side plate 61. The vertical plate 63 is connected with the bottom plate 62, and the vertical plate 63 and the bottom plate 62 form a second included angle β. In this embodiment, the number of the side plates 61 is two, the two side plates 61 are disposed in parallel and are pivotally connected to the corresponding brackets 50, the drum 20 is installed between the two side plates 61, and two ends of the bottom plate 62 are connected to the two side plates 61. The first included angle alpha is 90 degrees. The second included angle beta is 90 degrees. The first included angle α and the second included angle β may be other degrees in other embodiments.

In the present embodiment, the limiting portion is a limiting plate 68, and the limiting plate 68 is pivotally connected to the bottom plate 62 of the flipping base 60 through a rotating shaft 64. In this way, by the structure of the limiting plate 68, that is, by the limiting plate 68 rotating to the position matching with the slot 41, the roller 20 cannot pivot relative to the bracket 50 and is located above the vehicle platform 10 (working state); when the limiting plate 68 rotates away from the position matched with the slot 41, under the action of self gravity, the roller 20 can pivot relative to the bracket 50 to the lower part (the retracted state) of the vehicle platform 10, so that the opening or closing of the turnover door is not influenced. In this embodiment, a stop plate 42 is further disposed at one end of the slot 41 to stop the excessive rotation of the stop plate 68 away from the slot 41. The present invention realizes the locking of the rotation of the drum 20 by the cooperation of the limiting plate 68 pivoted to the flipping base 60 and the slot 41, but the present invention is not limited thereto. Alternatively, the rotation of the drum 20 can be locked by using other structures to complete the limit matching, for example, the limit portion is a protrusion which can be extended and retracted under the action of a spring so as to be clamped into the slot 41 or separated from the slot 41.

As shown in fig. 5 and 8, the roll-over stand 60 is further provided with a rotating shaft stand 66 and a bushing 67. The rotating shaft seat 66 is connected with the bottom plate 62 of the overturning seat 60 and is arranged below the bottom plate 62, and the limiting plate 68 is positioned below the rotating shaft seat 66. The shaft sleeve 67 is connected with the rotating shaft seat 66 and is positioned between the bottom plate 62 and the rotating shaft seat 66, and the rotating shaft 64 penetrates through the shaft sleeve 67.

The shaft 64 includes a head 641 and a shaft 642 connected to each other, wherein the head 641 has a diameter larger than that of the shaft 642. One end of the head 641 of the rotating shaft 64 close to the rod 642 abuts against one end of the bushing 67 close to the base plate 62. In this way, the rotation of the rotating shaft 64 is restricted by the bushing 67 without vertical movement by the structure of the rotating shaft holder 66 and the bushing 67, and the rotation of the rotating shaft 64 is more stable. Furthermore, the connection between the rotating shaft 64 and the limiting plate 68 is fixed by screws sequentially penetrating through the limiting plate 68 and the rotating shaft 64 from one side of the rotating shaft 64, and the screws are attached to the side surface of the limiting plate 68, so that the rotating shaft 64 and the limiting plate 68 are prevented from shaking. In other embodiments, the rotating shaft 64 and the limiting plate 68 can be fixed by other fixing members such as screws, bolts, or other fixing methods such as welding.

In this embodiment, the bottom plate 62 is opened with a through hole 621 corresponding to the rotation shaft 64, the central axis of the rotation shaft 64 coincides with the central axis of the through hole 621, the outer diameter of the head 641 of the rotation shaft 64 is smaller than the inner diameter of the through hole 621, and the head 641 of the rotation shaft 64 is lower than the upper surface of the bottom plate 62 along the vertical direction. In this embodiment, the rotating shaft 64 is a socket head cap screw, and the socket head cap wrench rotates the socket head cap screw to drive the rotating shaft 64 to rotate relative to the sleeve 67, so as to rotate the limiting plate 68 relative to the base plate 62. In other embodiments, the rotation of the limiting plate 68 can also be driven by a motor or other electric driving mechanism, and the flipping base 60 can also be flipped by the electric driving mechanism, and the driving mechanism of the flipping base 60 and the driving mechanism of the limiting plate 68 are matched with each other, for example, after the driving controller of the limiting plate 68 drives the limiting plate 68 to rotate away from the slot 41, a signal is sent to the driving controller of the flipping base 60, and after receiving the signal, the driving controller of the flipping base 60 controls the flipping base 60 to flip. Since the head 641 of the shaft 64 is below the upper surface of the base plate 62, the head will not cause any obstacle to the worker, i.e., the worker will not accidentally touch the head 641 of the shaft 64 during the work.

In this embodiment, as shown in fig. 9, the roller-overturning device 30 further includes an elastic member 80, and the elastic member 80 is sleeved outside the pivot shaft 70. The elastic member 80 includes a main body 81 and an extension 82 connected, and the extension 82 extends outward in a radial direction of the main body 81. Thus, by the structure of the elastic member 80, the elastic member 80 always applies an acting force to the pressing plate 611 to restore the flipping base 60 to the working state, thereby achieving the automatic resetting of the flipping base 60. The side plate 61 is provided with a pressing plate 611 at one end thereof close to the elastic member 80, and the pressing plate 611 abuts against the extending portion 82 of the elastic member 80. Thus, by the arrangement of the elastic member 80 and the pressing plate 611, the elastic member 80 can apply an acting force to the pressing plate 611 to restore the flipping base 60 to the working state, thereby achieving the automatic restoration of the flipping base 60.

As shown in fig. 6 and 7, the roller turnover device 30 further includes a turnover limiting member 90, and the turnover limiting member 90 fixes the turnover base 60 to the bracket 50 after the turnover base 60 is turned downward. The bracket 50 is provided with a through bracket limiting hole 51, the position of the turnover seat 60 corresponding to the bracket limiting hole 51 is provided with a turnover seat limiting hole (not marked in the figure) after the turnover seat 60 is turned downwards, and the turnover limiting piece 90 sequentially passes through the bracket limiting hole 51 and the turnover seat limiting hole to relatively fix the bracket 50 and the turnover seat 60. In this way, the position of the overturning seat 60 relative to the bracket 50 is fixed by sequentially penetrating the overturning limiting member 90 through the bracket limiting hole 51 and the overturning seat limiting hole, so that the overturning seat 60 is prevented from shaking due to the vibration of the vehicle carrying platform 10; meanwhile, the overturning seat 60 can be prevented from being restored to the working state under the action of the elastic member 80. When the overturn limiting member 90 does not fix the overturn base 60 and the bracket 50, it can be inserted into the bottom of the bracket 50 for easy access.
