Description

Technical Field

[0001] The invention relates to the technical field of aerial rail transportation, and in particular to a suspended monorail trolley reversing mechanism and a suspended monorail trolley. Background Art

[0002] The Skyrail train (abbreviated as Skyrail) is a suspended monorail transportation system. The track is above the train and supported in the air by steel or concrete columns. Since the Skyrail transportation system moves ground transportation into the air, it can alleviate urban traffic problems without expanding the city's existing road facilities; and since it only moves the track into the air, rather than lifting the entire road surface into the air like an elevated light rail or a riding monorail, it overcomes the shortcomings of other rail transportation systems and has many outstanding features and advantages in construction and operation. At present, the traditional Skyrail transportation system includes components such as track beams, support columns, Skyrail body, running mechanism and control system. Among them, the track beam of the system is a steel box beam, and the running mechanism drives the Skyrail body to move along the track beam.

[0003] Suspended monorail transportation (including cable rail transportation) has the advantages of economical and fast track construction, land saving, good spanning capacity, all-weather operation, and no need for human driving. However, due to its complex turnout technology and inability to turn autonomously, the traffic flow of suspended monorail is limited and traffic safety is difficult to guarantee.

[0004] Over the years, many technicians at home and abroad have proposed many technical solutions for turnouts of suspended monorail transportation to improve the switching speed, safety and reliability of turnouts and reduce the manufacturing, maintenance and operation costs of turnouts. However, the two steering wheels of existing skyrail trains are generally controlled independently, so that one of the steering wheels may fail to move successfully at the turn of the turnout. Once this happens, the wheels on both sides of the train will cross the two tracks respectively, causing wheel jamming, which is not only difficult to maintain, but also affects the operation of subsequent vehicles. Therefore, safety performance cannot be guaranteed. Summary of the invention

[0005] The purpose of the present invention is to provide a self-steering suspended single-track trolley reversing mechanism to avoid the accident of the trolley failing to turn at a turnout and running across the track.

[0006] Another object of the present invention is to provide a self-steering suspended single-track trolley to avoid accidents in which the trolley fails to turn at a switch and runs across the track.

[0007] In order to achieve the above-mentioned purpose, the present invention discloses a suspended single-track trolley reversing mechanism, comprising a carrier frame, a rocking member and a reversing drive member; the walking mechanism is installed in the track beam and connected to the track trolley through a carrier frame; the rocking member is installed outside the track beam and is pivotally connected to the carrier frame through a pivot joint, and the rocking member is provided with two lifting and lowering ends respectively located on both sides of the pivot joint, and the two lifting and lowering ends can swing up and down with the pivot joint as the swing center point, and the two lifting and lowering ends are respectively provided with a steering wheel located on the outside of the side wall of the track beam; the reversing drive member is connected to the rocking member, and is used to change the lifting and lowering state of the two lifting and lowering ends, so that the steering wheel on one of the lifting and lowering ends is located in the height plane where the track beam is located.

[0008] Compared with the prior art, the reversing mechanism of the suspended monorail trolley of the present invention is pivotally connected with a swing member on a carrier frame on which a walking mechanism is installed. The swing member moves along the track beam following the walking mechanism. A lifting end is respectively arranged on both sides of the swing member, and a steering wheel is provided on the two lifting ends. Under the action of the reversing driving member, the swing member swings up and down with the carrier frame as the swing center. Through the swinging action of the swing member, the lifting end on one side rises while the lifting end on the other side falls. In this way, one of the two lifting ends is always kept in a raised state and the other in a fallen state. When the swing member is installed under the track beam, the lifting end is in a fallen state. The steering wheel on the lifting and lowering end in the lower state is located below the track beam, and the steering wheel on the lifting and lowering end in the raised state is located in the height plane where the track beam is located. When the rail trolley travels to the switch, the steering wheel on the lifting and lowering end in the raised state contacts the outer wall of the track beam on the branch road and rotates along it, thereby pulling the rail trolley to the branch road to achieve the steering of the rail trolley; it can be seen that since the two steering wheels are in a linkage system through the rocking member, when the rail trolley turns, the wheel jamming caused by the uncoordinated state of the two steering wheels can be effectively avoided, thereby improving the safety performance of the rail trolley.

[0029] In order to explain in detail the technical content, structural features, implementation principles, and achieved purposes and effects of the present invention, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, the present invention discloses a suspended single track trolley, including a carriage 30 for carrying passengers, the carriage 30 is suspended on a carriage-type track beam 5 through a running mechanism 4, the carriage 30 is connected to the running mechanism 4 through a carrier 2, that is, the lower end of the carrier 2 is connected to the carriage 30, and the running mechanism 4 is installed on the upper end of the carrier 2, and the running of the running mechanism 4 in the track beam 5 drives the track trolley 3. In order to solve the problem of the track trolley 3 turning autonomously when it walks to the branch switch, a reversing mechanism is set on the carrier 2 in this embodiment, and the reversing mechanism includes a rocking member 1 and a reversing driving member. The rocking member 1 is installed outside the track beam 5, and can be installed above the track beam 5 or below the track beam 5. For the convenience of installation, in this embodiment, the rocking member 1 is installed below the track beam 5. The rocking member 1 is pivotally connected to the carrier 2 through a pivoting portion 10. Two lifting ends 11 are respectively located on both sides of the pivoting portion 10. The two lifting ends 11 can swing up and down with the pivoting portion 10 as the swing center point, that is, the two lifting ends 11 can move up and down with the carrier 2 as the fulcrum. When the lifting end 11 on one side of the rocking member 1 rises, the lifting end 11 on the other side of the rocking member 1 falls. A steering wheel 12 located on the outer side of the side wall of the track beam 5 is respectively provided on the two lifting ends 11. The reversing drive is connected to the rocking member 1 and is used to change the lifting and lowering state of the two lifting ends 11 so that the steering wheel 12 on the lifting end 11 that is tilted upward is within the height plane where the track beam 5 is located, such as Figure 1As shown in FIG, the height line where the top wall of the track beam 5 is located is L1, and the height line where the bottom wall of the track beam 5 is located is L2. Then, when one of the landing ends 11 tilts upward, the height line position of the steering wheel 12 on the landing end 11 is located between L1 and L2. When installing the steering wheel 12, it is best to make the axial direction of the steering wheel 12 parallel to the side wall of the track beam 5, so that the steering wheel 12 on the landing end 11 can slide along the outer side wall of the track beam 5 on the turnout.

[0031] The reversing process of the suspended monorail trolley with the above structure is as follows: the traveling mechanism 4 drives the carriage 30 to travel along the track beam 5. During the traveling process, the reversing drive component causes one of the lifting and lowering ends 11 on the rocking member 1 to be in a raised state. Since the two lifting and lowering ends 11 are in a seesaw-type linkage mechanism, the other lifting and lowering end 11 must be in a lowered state. When one of the lifting and lowering ends 11 is in a raised state, the steering wheel 12 thereon is located above the plane where the bottom wall of the track beam 5 is located, so that one of the radial directions of the steering wheel 12 points to the outer wall of the track beam 5. When the lifting and lowering end 11 is in a lowered state, the steering wheel 12 thereon is located below the plane where the bottom wall of the track beam 5 is located. Fig. 9 As shown, after the carriage 30 turns a branch switch, the reversing drive adjusts the lifting and lowering state of the rocking member 1 according to the turning direction of the next branch switch G2. For example, relative to the traveling direction of the rail trolley 3, if the front of the rail trolley 3 needs to turn to the right branch switch G2, the reversing drive controls the lifting and lowering end 11 on the right side of the rocking member 1 to lift up and the lifting and lowering end 11 on the left side to fall down. When the rail trolley 3 walks to the branch switch G2, the steering wheel 12 on the right lifting and lowering end 11 in the lifted state abuts against the outer wall of the track beam 5 of the branch switch G2. As the rail trolley 3 moves forward further, the steering wheel 12 on the right side pulls the traveling mechanism 4 toward the right branch switch G2 to realize the right turn of the rail trolley 3. After the turn is completed, the reversing drive drives the rocking member 1 to move in preparation for the next turn. It can be seen that since the two lifting ends 11 on the rocking member 1 are always kept in a state of one being raised and the other being dropped, that is, the two steering wheels 12 are always kept in a state of one being above the plane where the bottom wall of the track beam 5 is located and the other being below the plane where the bottom wall of the track beam 5 is located, when one of the lifting ends 11 changes state, it will inevitably drive the other lifting end 11 to change state accordingly. In this way, when the track trolley 3 needs to turn, even if it cannot turn successfully, it will continue to move along the original track. Please refer to Fig. 9Even if the rail trolley cannot turn to the fork road G2, it will walk along the original fork road G1, and one of the two steering wheels 12 will not abut on the fork road G2 and the other will abut on the fork road G1, thus avoiding the rail trolley 3 from walking across the track and causing damage to the rail trolley 3, thereby improving safety performance. In addition, for a distance before the rail trolley 3 turns, the rocking member 1 is always in a state of preparation for turning, so if there is a problem with the reversing mechanism, it can be known in advance so that countermeasures can be taken in advance.

[0032] It should be noted that the track matched with the reversing mechanism in the embodiment of the present invention is a single-branch track (such as Fig. 9 ), the reversing mechanism in the embodiment of the present invention is not suitable for use on double-forked tracks (such as Fig.10 )superior.

[0033] In order to prevent the rail trolley 3 from being unable to turn successfully when the reversing drive member fails or the rocking member 1 is stuck, in another preferred embodiment of the reversing mechanism of the present invention, a forced reversing drive mechanism is further provided, such as Figure 4 and Figure 5 As shown, the forced reversing drive mechanism includes a return wheel 13 respectively arranged at the two lifting and landing ends 11, and a wing plate 50 extending obliquely from top to bottom is arranged on the side wall corresponding to the front end of the branch switch on the track beam 5. Through the cooperation of the wing plate 50 and the return wheel 13, the lifting and landing end 11 on the corresponding side is forced to swing downward. If the track trolley 3 is about to enter the right fork road, the lifting end 11 on the right side of the track beam 5 should be in the raised state. However, if the two lifting ends 11 on the rocking member 1 fail to change, resulting in the lifting end 11 on the left side of the track beam 5 still being in the raised state, then as the track trolley 3 moves forward, the homing wheel 13 gradually approaches the wing plate 50 until it abuts against the wing plate 50. When the homing wheel 13 abuts against the wing plate 50, as the track trolley 3 moves forward further, the lifting end 11 on this side is pressed down by the homing wheel 13 under the low pressure of the wing plate 50, and the lifting end 11 on the other side is raised, thereby realizing the correct transformation of the rocking member 1. In this embodiment, the forced transformation of the rocking member 1 is realized through the mechanical structure, thereby ensuring the correct steering of the track trolley 3.

[0034] Regarding the installation structure of the rocking member 1, preferably, as Figure 4 As shown, a shaft sleeve 63 is provided on the carrier 2, a driving shaft 64 is provided on the shaft sleeve 63, the rocking member 1 is connected to the driving shaft 64 through the pivoting portion 10, and the driving shaft 64 drives the rocking member 1 to rock relative to the shaft sleeve 63. In this embodiment, the pivoting portion 10 on the rocking member 1 is driven to rotate by the rotation of the driving shaft 64 in the driving sleeve, thereby realizing the rocking action of the rocking member 1. Further, as Figure 2 and Figure 3, the reversing drive member includes a swing rod 60 and a power member, the swing rod 60 includes a connecting end 600 and a swing end 601, the swing rod 60 is connected to the drive shaft 64 through the connecting end 600, and the power member is used to drive the swing end 601 to swing. Taking the observation angle 2 as an example, when the power member drives the swing end 601 to swing to the left side, the connecting end 600 drives the drive shaft 64 to rotate clockwise, thereby driving the right side of the swing member 1 to fall and the left side of the swing end 11 to rise. It should be noted that in this embodiment, the swing end 601 can be located below the drive shaft 64 or above the drive shaft 64. Further, the power member includes two electromagnets 61 respectively arranged on both sides of the swing end 601, and the swing end 601 can be attracted by the two electromagnets 61 respectively. The swing end 601 can be realized by connecting the power to the two electromagnets 61 respectively. For easy installation, the swing rod 60 and the two electromagnets 61 are installed in a mounting box.

[0035] Please refer again Figure 1 and Figure 2 In another preferred embodiment of the suspended monorail trolley of the present invention, the traveling mechanism 4 includes a pair of traveling wheels 40 arranged on the carrier 2. When the track trolley 3 is docked with the track beam 5, the carriage 30 is suspended on the track beam 5 by the pair of traveling wheels 40, and the movement of the traveling wheels 40 along the track beam 5 drives the movement of the carriage 30. In order to ensure the stable movement of the traveling wheels 40 and avoid shaking the carriage 30, preferably, a group of guide wheels 41 that can rotate along the inner wall of the track beam 5 are respectively arranged at the front and rear ends of the traveling wheels 40 on the carrier 2. Each group of guide wheels 41 has two, and the two guide wheels 41 are arranged in an up-and-down staggered manner, and the two guide wheels 41 are respectively in contact with the inner walls of the two sides of the track beam 5. It can be seen that the pair of traveling wheels 40 are positioned at a fixed position of the track beam 5 by the two groups of guide wheels 41, so that the traveling wheels 40 will not deviate during the movement, thereby avoiding the shaking of the carriage 30.

[0036] In addition, in order to further enhance the stability of the carriage 30, as Figure 6 Two sets of running mechanisms 4 are installed on the top of the carriage 30, and a reversing mechanism with the above structure is installed on each running mechanism 4. The running wheels 40 in one set of running mechanisms 4 can be set as driving wheels, and the running wheels 40 in the other set of running mechanisms 4 can be set as driven wheels. The running wheels 40 as driving wheels are connected to the driving motor 42 in a transmission manner. Preferably, in order to avoid conflicts between the reversing driving members in the front and rear reversing mechanisms, the reversing driving members in the front and rear reversing mechanisms are preferably in the same linkage system. Specifically, in this embodiment, the electromagnets 61 in the front and rear reversing mechanisms are connected in series, so as to ensure that the front and rear steering wheels 12 move in unison.

[0037] Furthermore, the suspended monorail trolley of the present invention further comprises a pair of connecting mechanisms that can connect multiple monorail trolleys 3 together, and multiple monorail trolleys 3 can be connected into a multi-section train through the connecting mechanisms. Figures 6 to 8 The connecting mechanism includes a pair of hooks 80 and hanging blocks 81 that cooperate with each other. The hook 80 is installed on the support frame 2 at the front end of the carriage 30, and the hanging block 81 is installed on the support frame 2 at the rear end of the carriage 30. When the two rail trolleys 3 are close to each other, the hook 80 on the rear rail trolley 3 is engaged with the hanging block 81 on the front rail trolley 3, thereby realizing the connection of the rail trolley 3, and the assembly and disassembly are relatively convenient.

[0038] In summary, the suspended single track trolley of the present invention realizes the autonomous steering of the track trolley 3 by arranging a swing member 1 and a reversing drive member on the carrier 2 connected to the walking mechanism 4. The two steering wheels 12 on the swing member 1 can swing up and down in a linkage system, so that the two steering wheels 12 can change their states in linkage with each other through the swing of the swing member 1, thereby avoiding the phenomenon of cross-track walking caused by the inability of the two steering wheels 12 to move in linkage at the same time, and reducing the maintenance rate of the track trolley 3. Moreover, the state of the swing member 1 can be changed in advance before steering, so that the steering wheel 12 on the corresponding side is raised above the plane where the bottom wall of the track beam 5 is located, and the steering wheel 12 on the other side falls below the plane where the bottom wall of the track beam 5 is located, thereby avoiding the phenomenon that the track trolley 3 cannot turn at the branch point.

[0039] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
