As shown in fig. 1 and 2, the utility model discloses a suspension type monorail trolley, including the carriage 30 that is used for carrying the passenger, carriage 30 hangs on carriage style's track roof beam 5 through a running gear 4, and carriage 30 bears frame 2 through one and is connected with running gear 4, bears the lower extreme of frame 2 promptly and is connected with carriage 30, bears the upper end installation running gear 4 of frame 2, drives the walking of trolley 3 through the walking of running gear 4 in track roof beam 5. In order to solve the problem that the small rail car 3 travels to the branch point and turns autonomously, a reversing mechanism is arranged on the bearing frame 2 in the embodiment and comprises a swinging piece 1 and a reversing driving piece. The swinging member 1 is installed outside the track beam 5, and can be installed above the track beam 5, and also can be installed below the track beam 5, and for the convenience of installation, in the embodiment, the swinging member 1 is installed below the track beam 5. The swing piece 1 is pivotally connected with the bearing frame 2 through a pivot part 10, two lifting ends 11 respectively positioned at two sides of the pivot part 10 are arranged on the swing piece 1, the two lifting ends 11 can swing up and down by taking the pivot part 10 as a swing central point, namely the two lifting ends 11 can bear the frame 2 as a pivot point to do up-and-down lifting motion, when the lifting end 11 at one side of the swing piece 1 is lifted, the lifting end 11 at the other side of the swing piece 1 is descended, and the two lifting ends 11 are respectively provided with a steering wheel 12 positioned at the outer side of the side wall of the track beam 5. The reversing driving piece is connected with the swinging piece 1 and is used for changing the rising and falling states of the two rising and falling ends 11, so that the steering wheel 12 on the rising and falling end 11 which tilts upwards is positioned in the height plane of the track beam 5, as shown in fig. 1, the height line of the top wall of the track beam 5 is L1, the height line of the bottom wall of the track beam 5 is L2, and then when one of the rising and falling ends 11 tilts upwards, the height line position of the steering wheel 12 on the rising and falling end 11 is positioned between L1 and L2. The diverting pulley 12 is preferably mounted such that the axial direction of the diverting pulley 12 is parallel to the side wall of the track beam 5, so that the diverting pulley 12 on the landing end 11 can slide along the outer side wall of the track beam 5 on the branch.

The reversing process of the suspended monorail trolley with the structure is as follows: the running mechanism 4 drives the carriage 30 to run along the track beam 5, during the running process, the reversing driving piece enables one lifting end 11 on the swinging piece 1 to be in a lifting state, because the two lifting ends 11 are in a rocker type linkage mechanism, the other lifting end 11 is necessarily in a falling state, when one lifting end 11 is in the lifting state, the steering wheel 12 on the lifting end is located above the plane where the bottom wall of the track beam 5 is located, one of the steering wheel 12 is enabled to point to the outer side wall of the track beam 5 in the radial direction, and when the lifting end 11 is in the falling state, the steering wheel 12 on the lifting end is located below the plane where the bottom wall of the track beam 5 is located. As shown in fig. 9, after the car 30 turns over one branch switch, the reversing driving member adjusts the rising and falling state of the rocking member 1 according to the turning direction of the next branch switch G2, for example, in terms of the running direction of the trolley 3, if the front of the trolley 3 needs to turn to the right branch switch G2, the reversing driving member controls the rising and falling end 11 on the right side of the rocking member 1 to rise, the rising and falling end 11 on the left side falls, when the trolley 3 runs to the branch switch G2, the steering wheel 12 in the rising state on the right side rising and falling end 11 abuts against the outer side wall of the track beam 5 of the branch switch G2, with the further forward running of the trolley 3, the running gear 4 is pulled to the right branch switch G2 through the steering wheel 12 on the right side, so as to realize the right turn of the trolley 3, and after the turning is completed, the reversing driving member 1 acts to prepare for the next turn. Therefore, as the two landing ends 11 on the swinging member 1 are always kept in a rising state and in a falling state, that is, one of the two steering wheels 12 is always kept above the plane of the bottom wall of the track beam 5 and the other is kept below the plane of the bottom wall of the track beam 5, when the state of one of the landing ends 11 changes, the other landing end 11 is inevitably driven to change correspondingly, so that when the track trolley 3 needs to turn, even if the track trolley cannot turn successfully, the track trolley can continue to travel along the original track, please refer to fig. 9 again, even if the track trolley cannot turn to the branch track G2, the track trolley can travel along the original branch track G1, and one of the two steering wheels 12 cannot abut against the branch track G2, and the other abuts against the branch track G1, thereby avoiding the phenomenon that the track trolley 3 travels across tracks and further damages the track trolley 3, thereby improving safety performance. In addition, the swinging part 1 is always in a steering preparation state a certain distance before the rail trolley 3 is steered, and if a problem occurs in a steering mechanism, the problem can be known in advance so as to take a countermeasure in advance.
