[0038] The plurality of transportation sections 2 are arranged in sequence from top to bottom, and the upper adjacent transportation section 2 and the lower adjacent transportation section 2 have a height staggered area, which means that in the upper adjacent transportation section 2, the lowermost end of the upper transportation section 2 is lower than the uppermost end of the lower transportation section 2, and the height staggered area serves as a transition area for the transportation cabin 1; at least three transportation cable driving assemblies 201 are arranged in each transportation section 2, which are arranged in a ring shape, spaced apart, uniform and vertical, which is beneficial to the force balance of the transportation cable driving assemblies 201 and the smooth transportation of the transportation cabin 1; each of the at least three transportation cable driving assemblies 201 can be reversibly connected with the transportation cabin 1, which means that the transportation cable driving assembly 201 and the transportation cabin 1 can be connected or disconnected, when the transportation cabin 1 needs to be transported by the transportation cable driving assembly 201 in the transportation section 2, the transportation cable driving assembly 201 in the transportation section 2 is connected with the transportation cabin 1, and when the transportation cabin 1 does not need to be transported by the transportation cable driving assembly 201 in the transportation section 2, the transportation cable driving assembly 201 in the transportation section 2 is disconnected with the transportation cabin 1; in the upper adjacent transportation section 2 and the lower adjacent transportation section 2, the at least three transportation cable driving assemblies 201 in the upper transportation section 2 and the at least three transportation cable driving assemblies 201 in the lower transportation section 2 are spaced apart in the horizontal plane of the height staggered area, so as to avoid interference between the upper adjacent transportation cable driving assembly 201 and the lower adjacent transportation cable driving assembly 201.

[0040] When the transport cabin 1 needs to be transported vertically downward, in the upper and lower adjacent transport sections 2, at least three transport cable drive assemblies 201 in the transport section 2 above are connected with the transport cabin 1 to transport the transport cabin 1 vertically downward to the corresponding height staggered area, and after at least three transport cable drive assemblies 201 in the transport section 2 below are connected with the transport cabin 1, at least three transport cable drive assemblies 201 in the transport section 2 above are disconnected with the transport cabin 1, at this time, at least three transport cable drive assemblies 201 in the transport section 2 below drive the transport cabin 1 to move vertically downward, thereby, the transport cabin 1 can be transported vertically downward by relay through the transport cable drive assemblies 201 in the plurality of transport sections 2.

[0041] According to the relay type vertical transport system 1000 of the embodiment of the present application, by reversibly connecting the plurality of transport sections 2 and the transport cable drive assemblies 201 in each transport section 2 with the transport cabin 1, on the one hand, the automatic relay of the transport cabin 1 between the transport sections 2 is realized, thereby realizing the relay transport of the transport cabin 1 vertically upward and downward, and the personnel and materials in the transport cabin 1 do not need to be transferred in the transport process, ensuring the safety, convenience and efficiency of the transport, on the other hand, the gravity load of the relay type vertical transport system 1000 of the embodiment of the present application is distributed to different heights, the weight of the relay type vertical transport system 1000 of the embodiment of the present application is as evenly distributed as possible along the transport height, avoiding the problem that the length of a single cable of the existing transport system is too long in the process of super-high transport and avoiding the problem that the self-weight of the transport system borne by the top of the existing transport system is too large.

[0042] In some embodiments, each transport cable drive assembly 201 comprises a vertically straightened closed loop transport cable 2011, an upper pulley 2012 and a lower pulley 2013, the upper end and the lower end of the transport cable 2011 are correspondingly sleeved on the upper pulley 2012 and the lower pulley 2013 respectively, the transport cable 2011 is reversibly connected with the transport cabin 1, one of the upper pulley 2012 and the lower pulley 2013 serves as a power wheel, the power wheel can rotate bidirectionally under the drive of a drive machine 2014, so that the points on the transport cable 2011 move up and down, thereby driving the transport cabin 1 connected with the transport cable 2011 to move up and down.

[0043] In some embodiments, each transport cable drive assembly 201 further comprises a counterweight 2015, the counterweight 2015 is arranged on the transport cable 2011 to balance the weight of the transport cabin 1.

[0044] In some embodiments, the reversible connection between the transport cable 2011 and the transport cabin 1 is realized through a reversible connecting piece 3.

Thus, by providing the safety device 101, when the connection between the transport ring 301 and the transport cabin 1 is unstable or fails, the safety device 101 is opened to prevent the transport cabin 1 from falling off the transport ring 301, ensuring that the transport ring 301 of the transport section 2 can still realize vertical transportation of the transport cabin 1, and the transportation is safer and more reliable.
