Description

Technical Field

[0001] The present application relates to the technical field of suspended rail transportation, and in particular to a transportation mechanism for a suspended rail system and a suspended rail system. Background Art

[0002] With the development of urbanization, urban land is becoming increasingly scarce, resulting in the increasing cost of existing ground infrastructure construction, which in turn exacerbates urban traffic pressure. Correspondingly, the advantage of suspended rail transit facilities in occupying less space is gradually emerging. Whether it is the ground area occupied or the vertical space occupied, the suspended rail transit is smaller; during construction, less space is needed to build piers on the ground to carry the track, and the space under the track can be freely passed, so the suspended rail transit can alleviate urban traffic pressure.

[0003] When the suspended rail system is used for cargo transportation, especially the lifting and horizontal transportation of containers, the lifting and transportation process of the containers usually adopts a conventional chain lifting structure, and this conventional chain lifting structure is connected to a power bogie. Summary of the invention

[0004] In actual use, after the conventional chain lifting structure is applied to connect the power unit, especially the power bogie, it is generally two power bogies connected to a lifting structure separately. During the lifting process, the container needs to be well positioned. Since the power bogie is connected to the lifting mechanism separately, both power bogies need to be positioned at the same time. If one of the positions deviates, the lifting process requires more manual assistance. At the same time, during the lifting process, since the chain structure is connected to the power bogie separately, if the lifting speed of the container is too fast, it is easy to shake. During transportation, the power bogie may have speed deviations due to actual working conditions. At this time, the container carried below it is more likely to shake. The faster the speed, the more obvious the frequency and amplitude of the shaking.

[0005] The present application provides a transport mechanism and a suspended track system for a suspended track system, aiming to solve the problem that after a conventional lifting mechanism is used in a suspended track system, lifting and transporting containers is prone to shaking, thus affecting the lifting and transporting speed of the containers.

[0006] To achieve the above-mentioned purpose, according to the first aspect of the present application, the present application proposes a transport mechanism for a suspended track system, comprising: at least two power bogies, at least two suspension devices, at least two lifting mechanisms, a crossbeam and a hanger; wherein any suspension device is connected to the bottom of any power bogie,

[0007] Among the at least two lifting mechanisms, the upper end of each lifting mechanism is connected to the bottom of the corresponding suspension device, and the lower end of each lifting mechanism is hung and connected to the sling;

[0008] The two ends of the cross beam are respectively connected to the top of the at least two power bogies.

[0009] Optionally, the sling is provided with a lock, and the suspension device is provided with a locking piece matching the lock.

[0010] Optionally, the suspension device is connected to a lifting drive device, and the lifting drive device drives the lifting mechanism to move up and down.

[0011] Optionally, the lifting mechanism includes a chain transmission member.

[0012] Optionally, the sling is provided with an alignment device and an alignment drive device connected to the alignment device.

[0013] Optionally, the alignment device is respectively arranged at least at the four corners of the sling.

[0014] Optionally, the spreader is provided with a plurality of locking members matched with the containers.

[0015] Optionally, any of the power bogies includes at least two rotating shafts, and the suspension device is arranged between the two rotating shafts.

[0016] Optionally, the suspension device is provided with a stabilizing structure.

[0017] According to a second aspect of the present application, there is also provided a suspended track system, which comprises a track beam and a transport mechanism as described in any one of the above items, wherein at least two power bogies included in the transport mechanism both travel along the track beam.

[0018] The transport mechanism for the suspended rail system provided by the technical solution of the present application has a crossbeam connecting two power bogies arranged above the power bogie, which can effectively stabilize the balance difference between the two power bogies, thereby effectively reducing the shaking frequency and shaking amplitude of the container during lifting and transportation, and effectively realizing the lifting or transportation of the container at a specific speed. The working process of the transport mechanism of the present application is as follows:

[0019] The lifting mechanism descends, and the sling fixes the container. After fixation, the lifting mechanism rises, and the container is lifted to the transportation position under the action of the lifting mechanism and the sling. After the transportation is completed, the lifting mechanism descends, and the sling releases the container. The lifting mechanism and the sling are reset to complete the lifting and transportation process. Through the above process, the transportation mechanism for the suspended track system provided by the present application can solve the problem that when the existing conventional chain lifting mechanism is applied to the suspended track system, the lifting and transportation of the container is prone to shaking, thereby affecting the lifting and transportation speed of the container.

[0033] For the specific structure of the transport mechanism of the suspended track system used in the present application, please refer to Figure 1 and Figure 2 , Figure 1 is a three-dimensional schematic diagram of a transportation mechanism for a suspended track system provided in an embodiment of the present application; Figure 2 yes Figure 1 Side view of an unloaded container. Figure 1 and Figure 2 As shown, the transportation mechanism of the suspended track system includes:

[0034] At least two power bogies 100 , at least two suspension devices 200 , at least two lifting mechanisms 400 , a crossbeam 300 and a sling 500 .

[0035] The at least two power bogies 100 are arranged along Figure 3 The track beams 800 shown are in operation and are fixedly connected to each other via the cross beam 300 , thereby maintaining the two power bogies 100 in stable travel.

[0036] Among the at least two lifting mechanisms 400 , the upper end of each lifting mechanism 400 is connected to the lower side of the corresponding suspension device 200 , and the lower end of each lifting mechanism 400 is hung and connected to the sling 500 .

[0037] The upper end of the lifting mechanism 400 is connected to the lower part of the suspension device 200 connected to the corresponding power bogie 100, and the lower end thereof is hung and connected to the sling 500. Therefore, after the sling 500 is used to fix the container, the lifting mechanism 400 can lift the sling 500 fixing the container to the lower part of the power bogie 100, and since the power bogie 100 is moved along the Figure 3 The track beam 800 shown is moving; the specific structural setting, especially the setting of the crossbeam, shortens the overall structural height of the transportation mechanism, and effectively reduces the increase in the load below the power bogie. At the same time, the transportation mechanism is not prone to shaking when moving along the track beam.

[0038] Both ends of the cross beam 300 are connected to the top of the at least two power bogies 100 respectively.

[0039] The at least two power bogies 100 are fixedly connected at both ends of the crossbeam 300, so that the two power bogies 100 can remain parallel in a horizontal position, and the two power bogies 100 run synchronously and remain stable when moving along the track beam 800.

[0040] Please refer to Figure 3 to Figure 6 , Figure 3 It is a structural schematic diagram of a suspension rail system provided in an embodiment of the present application when lifting a container; Figure 4 It is a structural schematic diagram of a suspension rail system provided in an embodiment of the present application when lifting a container; Figure 5 yes Figure 3 a side view of the suspended track system shown; Figure 6 yes Figure 4 A side view of the suspended track system is shown. Figure 3 to Figure 6 As shown, the suspended track system includes: a track beam 800 and Figure 1-2 The transport mechanism shown in the figure comprises at least two power bogies 100 which both travel along the track beam 800 .

[0041] The above-mentioned transportation mechanism for the suspended track system includes at least two power bogies 100 that both move along the track beam 800, and it uses the transportation mechanism described in the present application to hang the container 600. When the container is being lifted or lowered and the power bogies 100 move along the track beam 800, the container 600 is not prone to shaking.

[0042] In summary, in the technical solution provided in the embodiment of the present application, the lifting mechanism descends, the sling fixes the container, and after fixation, the lifting mechanism rises, and the container is lifted to the transportation position under the action of the lifting mechanism and the sling. After the transportation is completed, the lifting mechanism descends, the sling releases the container, and the lifting mechanism and the sling are reset to complete the lifting and transportation process. Through the above process, the transportation mechanism for the suspended track system provided by the present application can solve the problem that when the existing conventional chain lifting mechanism is applied to the suspended track system, the lifting and transportation of the container is prone to shaking, thereby affecting the lifting and transportation speed of the container.

[0043] In addition, in order to realize the lifting and transportation of containers, the container transportation is lifted to the appropriate position and combined with Figure 1 and Figure 3 As shown, the suspension device is connected to a lifting drive device, and the lifting drive device drives the lifting mechanism to move up and down.

[0044] By, for example, providing a lifting drive device 202 connected to each suspension device 200 , the lifting drive device 202 can drive the lifting mechanism 400 to lift and lower as a whole, and realize the lifting and lowering of the container 600 through the hanger 500 hung on the lifting mechanism 400 .

[0045] like Figure 3 As shown, the lifting mechanism 400 includes a chain transmission member. The chain transmission member is connected to Figure 1 As shown, the lifting mechanism 400 hangs the lifting device 500 between the lifting drive device 202 and the lifting device 500, so the lifting device 500 can be driven to rise and fall quickly through the chain transmission member, so as to lift the container 600 to a designated position.

[0046] In addition, if Figure 3 and Figure 4 As shown, the lifting device 500 is provided with an alignment device 501 and an alignment driving device connected to the alignment device 501 .

[0047] By driving the alignment device 501 through the alignment drive device, the effective positioning of the container by the spreader can be achieved. Figure 3 As shown, the alignment device 501 is at least respectively arranged at the four corners of the lifting device 500 .

[0048] As shown in the figure, the spreader 500 is provided with a plurality of locking members 502 that match and connect with the container; through the locking members, the spreader 500 can firmly fix and release the container, and the lifting mechanism 400 drives the spreader 500 to lift the container to a designated position through the spreader 500.

[0049] In addition, if Figure 3 and Figure 4 Among the at least two power bogies 100 mentioned above, any power bogie 100 includes two rotating shafts 101 , and the suspension device 200 is disposed between the two rotating shafts 101 .

[0050] At least two rotating shafts 101 of the power bogie 100 are used to move along the track beam 800, so that the power bogie 100 can move along the track beam, and the suspension device 200 is arranged between the two rotating shafts 101, so when the power bogie 100 moves through the rotating shaft 11, the lifting mechanism 400 moves along the track beam. At the same time, the structural design of the crossbeam enables the container under the lifting mechanism 400 to maintain stability during operation, thereby improving the transportation efficiency of the container by the transportation mechanism.

[0051] In addition, if Figure 3 to Figure 6 As shown, the spreader 500 is provided with a lock 503, and the suspension device 200 is provided with a locking member 201 matching the lock 503. Under such a setting, after the spreader 500 lifts the container until the spreader 500 reaches the position of the suspension device 200, the lock 503 provided on the spreader 500 matches and locks with the locking member 201 provided on the suspension device 200, thereby effectively improving the stability of the spreader 500, especially during the container transportation process.

[0052] The transportation mechanism of the present application may also be provided with a stabilizing structure 203 at the location of the suspension device 200 to more effectively improve the transportation stability of the suspension device 200 .

[0053] The following will apply the transport mechanism of the present application to the suspended track system and conduct corresponding test calculations, among which the load 30 tons The container was tested at different lifting speeds V1, lowering speeds V2 and transport speeds V3, and the sway amplitude X, sway frequency H, lateral acceleration D and stability index W of the container at each speed were measured.
