DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] The embodiment of the present invention provides a safe tower climbing device, which can be referred to Figure 2 As shown in the figure, the safety tower climbing device is mainly used in the climbing operation of communication towers. In some cases, it can also be used in the climbing operation of high buildings with ladders such as water towers, power towers, industrial chimneys, and high-rise buildings. The structure of ladder 2 is the structure of a common industrial ladder. For details, please refer to Figure 5 As shown in FIG, the climbing ladder 2 includes two vertically arranged main body members and a plurality of stepping rods 3 arranged in parallel between the main body members.

[0048] For reference Figure 1 and Figure 3As shown, the safe tower climbing device specifically includes a safety seat and an alternating tower climbing mechanism. In this embodiment, the structure of the safety seat is similar to that of a common seat, specifically including a back plate 7 and a seat plate 8. When climbing the tower, the operator can sit on the seat plate 8 and lean on the back plate 7. This improves the comfort of the safe tower climbing device, helps the operator save physical strength, and is conducive to improving the efficiency of subsequent operations. The setting of the back plate 7 also provides safety protection behind the operator, which can prevent the operator from accidentally falling from the back of the safety seat.

[0049] The safety seat is provided with a traction end, which is used to be connected to the traction device in a transmission manner so that the safety seat can be raised or lowered. The traction end can specifically be a part of the back plate 7, or a part of the seat plate 8. The specific number, location, and structure of the traction end depend on actual needs. If the traction device is a winch 4, the winch 4 is directly fixed to the safety seat through the traction rope 5 to drive the safety seat to rise or fall. Based on such a lifting scenario, the traction end can specifically be the upward end of the back plate 7, or the edge of the seat plate 8, or a protrusion or hole groove on the back plate 7 or the seat plate 8, etc. I will not list them one by one here.

[0050] The alternating tower climbing mechanism includes at least one telescopic limit component group, and each telescopic limit component group includes at least two telescopic limit components. The telescopic limit component can be limited with the stepping rod 3 of the ladder 2 when the safety seat is rising or falling, so as to eliminate the safety hazard of the safety seat stalling. The telescopic limit components in the same group or in different groups move alternately, that is, after a telescopic limit component is limited with the stepping rod 3 of the ladder 2, another telescopic limit component starts to move to the next or previous stepping rod 3 until the telescopic limit component is limited with the stepping rod 3 of the next or previous level.

[0051] Specifically, if the alternating tower climbing mechanism specifically includes only one group of telescopic limit components, this group of telescopic limit components can operate alternately. When climbing, after one of the telescopic limit components is limited by the stepping rod 3 of the ladder 2, the other telescopic limit component can move to the upper stepping rod 3. After the latter telescopic limit component is limited by the stepping rod 3 of the upper level, the former telescopic limit component can move to the stepping rod 3 of the upper level. This is repeated, so that during the ascent of the safety seat, it is always ensured that there is a telescopic limit component that is limited by the stepping rod 3 of the ladder 2. When the safety seat descends, the alternating movement process of the telescopic limit component is the reverse of the aforementioned ascent process, which will not be repeated here.

[0052] For another example, when the alternating tower climbing mechanism includes two or more telescopic limit assembly groups, the telescopic limit assemblies in the same group can operate synchronously, and the telescopic limit assemblies in different groups operate alternately. Alternatively, the telescopic limit assemblies in the same group operate alternately, and the telescopic limit assemblies in different groups operate synchronously. Alternatively, the telescopic limit assemblies in the same group operate alternately, and the telescopic limit assemblies in different groups also operate alternately. For ease of understanding, this embodiment is described in detail with reference to a specific example:

[0053] It is now assumed that the alternating tower climbing mechanism includes two telescopic limit component groups, and the two telescopic limit component groups each include two telescopic limit components. The two telescopic limit components are arranged horizontally symmetrically relative to the safety seat. One of the telescopic limit component groups is located above the other telescopic limit component group. For the convenience of calling, the telescopic limit components located above are temporarily referred to as the first telescopic limit components 9, and the telescopic limit components located below are temporarily referred to as the second telescopic limit components 10. When climbing, the first telescopic limit component 9 moves synchronously from the initial position to the upper level pedal rod 3, and the second telescopic limit component 10 synchronously maintains a limited position with the pedal rod 3 at the initial position. After the first telescopic limit component 9 is limitedly matched with the upper level pedal rod 3, the second telescopic limit component 10 is synchronously moved to the upper level pedal rod 3 relative to the second telescopic limit component 10. After the second telescopic limit component 10 is limitedly matched with the upper level pedal rod 3 relative to it, the safety seat rises a certain distance under the traction of the external traction device. Repeat this process until the safety seat rises to a predetermined position. When the safety seat is lowered, the operation process of the telescopic limit assembly is the reverse of the above process, which will not be described here.

[0054] Alternatively, the above structure may also adopt such an alternating motion mode. When climbing, one of the first telescopic limit assemblies 9 moves from the initial position to the upper step rod 3, and the other first telescopic limit assemblies 9 remain at the initial position. The second telescopic limit assemblies 10 respectively keep synchronous movement with the corresponding first telescopic limit assemblies 9 above them. When the safety seat descends, the operation process of the telescopic limit assembly is the reverse of the above process, which will not be described here.

[0055] Alternatively, when climbing, one of the first telescopic limit assemblies 9 moves from the initial position to the upper pedal bar 3, and the other first telescopic limit assembly 9 remains in the initial position. The second telescopic limit assembly 10 maintains the opposite movement state to the corresponding first telescopic limit assembly 9 above it. That is, if the upper first telescopic limit assembly 9 moves to the upper pedal bar 3, the second telescopic limit assembly 10 below the first telescopic limit assembly 9 remains in place; if the upper first telescopic limit assembly 9 remains in place, the second telescopic limit assembly 10 below the first telescopic limit assembly 9 moves toward the upper pedal bar 3 relative to itself. When the safety seat descends, the operation process of the telescopic limit assembly is the reverse of the above process, which will not be repeated here.

[0056] It should be emphasized that "the alternating tower climbing mechanism includes two telescopic limit component groups, and the two telescopic limit component groups each include two telescopic limit components. The two telescopic limit components are arranged symmetrically with respect to the safety seat" is only a specific example given for the convenience of explanation. In actual implementation, the alternating tower climbing mechanism may also include one, three, four or even more telescopic limit component groups, and each telescopic limit component group may also include three, four or even more telescopic limit components. On this basis, the arrangement position of the telescopic limit component depends on the specific actual needs, which will not be repeated here.

[0057] For reference Figure 3 As shown, the telescopic limit assembly specifically includes a sliding mechanism, a telescopic member 19 and a movable limit mechanism. Among them, the sliding mechanism includes a fixed part and a sliding part, the fixed part is fixedly mounted on the safety seat, and the sliding part is movably mounted on the fixed part and can move along the length extension direction of the fixed part. The length extension direction of the fixed part is preferably arranged in the vertical direction, or arranged along the height extension direction of the communication tower 1, or arranged obliquely relative to the height extension direction of the communication tower 1.

[0058] In this embodiment, the telescopic member 19 can be protected in a storage box 15. That is, the storage box 15 is fixedly connected to the aforementioned sliding part, and the fixed end of the telescopic member 19 is fixedly installed in the storage box 15. The telescopic end of the telescopic member 19 can be extended or retracted along the first direction X. Figure 3 As shown, the first direction X is different from the length extension direction of the fixed portion, and is preferably perpendicular to the length extension direction of the fixed portion. The telescopic end of the telescopic member 19 is fixedly connected to the movable limiting mechanism. Based on the synthesis of the sliding mechanism and the motion path of the telescopic member 19, the movable limiting mechanism can cooperate with the stepping rod 3 of the ladder 2 on the communication tower 1 when the telescopic member 19 is extended, and cooperate with the stepping rod 3 of the ladder 2 on the communication tower 1 when the telescopic member 19 is retracted.

[0059] On the basis of the above structure, the fixed part can be specifically a guide box 11, and the sliding part can be a sliding block 14. The guide box 11 can be specifically a long strip box body, and a long strip through slot is provided on one side of the box body for the sliding block 14 to extend out. The sliding part is slidably installed in the guide box 11, and one end extends out of the long strip through slot and is connected to the fixed end of the telescopic member 19.

[0060] For reference Figure 4 As shown, the sliding mechanism further includes an upper liquid capsule 12, a lower liquid capsule 13 and a liquid supply assembly. The upper liquid capsule 12 is disposed between the upper side of the inner cavity of the guide box 11 and the upper side of the sliding block 14, and the lower liquid capsule 13 is disposed between the lower side of the inner cavity of the guide box 11 and the lower side of the sliding block 14. The liquid supply assembly is connected to the upper liquid capsule 12 and the lower liquid capsule 13 so as to provide liquid medium to the upper liquid capsule 12 and the lower liquid capsule 13.

[0061] The liquid supply assembly may specifically include a liquid tank 16, which is specifically fixedly suspended on the back plate 7 of the safety seat. A first pump 17 is fixedly connected to the top of the liquid tank 16, and the mouth of the first pump 17 extends to the interior of the upper liquid capsule 12, so as to pump the liquid medium into and out of the upper liquid capsule 12. A second pump 18 is fixedly connected to the bottom of the liquid tank 16, and the mouth of the second pump 18 extends to the interior of the lower liquid capsule 13, so as to pump the liquid medium into and out of the lower liquid capsule 13. When the sliding block 14 needs to move upward, the liquid medium in the upper liquid capsule 12 can be refluxed into the corresponding liquid tank 16 under the action of the first pump 17, and the second pump 18 can pump the liquid medium from the corresponding liquid tank 16 into the lower liquid capsule 13. At this time, the upper liquid capsule 12 shrinks, the lower liquid capsule 13 expands and forces the sliding block 14 to move upward. When the sliding block 14 needs to move downward, the liquid medium in the lower liquid capsule 13 can be made to flow back into the corresponding liquid tank 16 under the action of the second pump 18, and the first pump 17 can pump the liquid medium from the corresponding liquid tank 16 into the upper liquid capsule 12. At this time, the lower liquid capsule 13 shrinks, the upper liquid capsule 12 expands and forces the sliding block 14 to move downward. In this way, the sliding mechanism designed based on the hydraulic principle can meet greater load requirements. At the same time, since the pump generally has a certain pressure-maintaining capacity, the above sliding mechanism can achieve self-locking of the position of the sliding block 14 to a certain extent.

[0062] Of course, the upper liquid capsule 12 and the lower liquid capsule 13 can also be replaced by power sources such as electric cylinders, air cylinders, and hydraulic cylinders that can output linear motion. These power sources are generally arranged on both sides of the sliding block 14 together with the upper liquid capsule 12 and the lower liquid capsule 13. The fixed end of the power source is fixed on the guide box 11, and the power output end is fixedly connected to the sliding block 14. When an electric cylinder is used, the aforementioned liquid tank 16 needs to be changed to a battery; when a gas cylinder is used, the aforementioned liquid tank 16 needs to be changed to a gas cylinder. In addition, in order to save space, in the embodiment of the present invention, the telescopic limit assemblies that move synchronously can share a liquid tank 16.

[0063] The movable limiting mechanism may specifically include a limiting frame 21, a limiting block 23 and a limiting block driving member 22. The limiting frame 21 is arranged on the telescopic end of the telescopic member 19, so as to realize the limiting cooperation with the stepping rod 3 of the ladder 2 on the communication tower 1 or disengage the limiting cooperation with the stepping rod 3 of the ladder 2 on the communication tower 1 under the drive of the sliding mechanism and the telescopic member 19.

[0064] For reference Figure 3 and Figure 6 As shown, the limit frame 21 has a limit cavity for limiting the position with the stepping rod 3 and an opening for the stepping rod 3 of the climbing ladder 2 to extend into the limit cavity. In the embodiment of the present invention, the limit frame 21 can be a frame structure with an opening facing downward and a U-shaped cross section. The limit block 23 is movably arranged at the opening of the limit frame 21, and the limit block driving member 22 is arranged on the limit frame 21, and a hydraulic rod can be selected specifically. The power output end of the limit block driving member 22 is transmission-connected with the limit block 23 to drive the limit block 23 to move. When the limit frame 21 is limited with the stepping rod 3, the limit block 23 extends to the bottom of the stepping rod 3 and prevents the stepping rod 3 from escaping from the opening of the limit frame 21; when the limit frame 21 is out of the limit position with the stepping rod 3, the limit block 23 moves to the side of the stepping rod 3 to expose the opening and facilitate the stepping rod 3 to escape from the limit frame 21. Of course, the opening of the limiting frame 21 may also be oriented toward other sides, and in this case, the arrangement of the limiting block 23 and the limiting block driving member 22 remains unchanged.

[0065] For reference Figure 3 As shown, the movable limit mechanism may also include a limit frame driver 46. The limit frame driver 46 is fixedly mounted on the telescopic end, and the power output end of the limit frame driver 46 is fixedly connected to the limit frame 21. In this embodiment, the limit frame driver 46 may be a telescopic rod. The fixed end of the telescopic rod is fixedly connected to the telescopic end of the aforementioned telescopic member 19 through a connecting arm 20, and the telescopic end of the telescopic rod is fixedly connected to the limit frame 21 as a power output end. The extension direction of the power output end of the limit frame driver 46 depends on the opening direction of the limit frame 21. In this embodiment, the opening of the limit frame 21 is arranged downward, so the extension direction of the power output end of the limit frame driver 46 is arranged vertically. When the limit frame 21 is out of the limit fit with the stepping rod 3, the limit frame driver 46 can lift the limit frame 21 in advance, and then further move away from the stepping rod 3 under the drive of the telescopic member 19 and the sliding mechanism to prevent the limit frame 21 from interfering with other structures of the ladder 2 during the movement. The setting of the limit frame driving member 46 can share the travel of the sliding mechanism and the telescopic member 19, which can simplify the actions of the sliding mechanism and the telescopic member 19 when climbing the tower, thereby reducing the control cost.

[0066] In addition, the safety tower climbing device can optionally include a safety guardrail. Specifically, in an embodiment of the present invention, the safety guardrails are arranged in pairs. Each safety guardrail is composed of an upper crossbar 39, a lower crossbar 45 and two columns 44. The upper crossbar 39 and the lower crossbar 45 are arranged horizontally and spaced apart, and the two columns 44 are fixedly connected between the two crossbars. Two rotating platforms 38 arranged spaced apart from each other are arranged on the horizontal sides of the back plate 7 of the safety seat, and the upper crossbar 39 and the lower crossbar 45 are respectively hinged on the corresponding rotating platforms 38. A latch mechanism is provided on the safety guardrail, and a socket 43 for positioning and matching with the extended end of the latch mechanism is provided on the safety seat. When the operator rides on the safety tower climbing device, the extended end of the latch mechanism can be pulled out from the socket 43 to open the safety guardrail. When the operator has sat on the safety seat, the safety guardrail can be reset, and the extended end of the latch mechanism can be reinserted into the socket 43 to fix the safety guardrail to the side of the operator. Under the protection of the safety guardrail, the operator is less likely to fall from the horizontal side of the safety seat, so the above structure can further ensure the personal safety of the operator.

[0067] On this basis, the latch mechanism may specifically include a latch 42 and a latch drive assembly. The latch drive assembly is fixedly mounted on the safety guardrail, and the latch 42 is fixedly mounted on the power output end of the latch drive assembly. Under the drive of the latch drive assembly, the latch 42 can be inserted into and removed from the aforementioned socket 43 as the protruding end of the latch mechanism. Figure 3 As shown, in the embodiment of the present invention, the latch driving assembly specifically includes a driving box 40 and a latch driving ball screw 41 screwed to the driving box 40. One end of the latch driving ball screw 41 is fixedly connected to the latch 42, and the other end is exposed as a power input end. When in use, the operator manually turns the latch driving ball screw 41, so that the latch 42 is driven by the latch driving ball screw 41 to insert and remove the aforementioned insertion hole 43.

[0068] The safe tower climbing device may also include auxiliary mechanisms. Figure 1As shown, the auxiliary mechanism specifically includes a storage box 25, a tool box 37, a movable platform 28 and a movable platform driving assembly. In this embodiment, the storage box 25 is fixedly installed under the safety seat, the movable platform driving assembly is fixedly installed on the upper side of the storage box 25, and the movable platform 28 is slidably installed on the lower side of the storage box 25. The storage box 25 has at least one opening in the horizontal direction, so that the movable platform 28 can extend from the opening to the outside of the storage box 25 and retract from the opening to the inside of the storage box 25. The movable platform driving assembly includes a first servo motor 26 and a first ball screw 27 rotatably installed on the inner cavity of the storage box 25. The output end of the first servo motor 26 is connected to one end of the first ball screw 27, and the first ball screw 27 is screwed with an intermediate piece, which is fixedly connected to the movable platform 28 as the power output end of the movable platform driving assembly. The tool box 37 is arranged on the movable platform 28 so as to be received into the storage box 25 or moved out of the storage box 25 along with the movable platform 28.

[0069] For reference Figure 1 , Figure 5 As shown, the auxiliary mechanism may also include a lifting mechanism, and the lifting mechanism includes at least two lifting components arranged in stages. In this embodiment, the lifting mechanism is specifically a two-stage structure, that is, the lifting component located at the first stage is installed on the movable platform 28, the lifting drive component of the second stage is installed on the lifting end of the lifting component of the first stage, and the tool box 37 is fixedly installed on the lifting end of the lifting component of the second stage. Specifically, the lifting component of the first stage includes a first vertical rail 29, a second servo motor 32 and a second ball screw 30. The second servo motor 32 is fixedly installed at the bottom of the inner cavity of the first vertical rail 29, and the second ball screw 30 is rotatably installed in the inner cavity of the first vertical rail 29. The output end of the second servo motor 32 is connected to the lower end of the second ball screw 30, and the first moving block 31 is screwed on the second ball screw 30. Driven by the second servo motor 32, the first moving block 31 can move up and down relative to the second ball screw 30.

[0070] The first-stage lifting assembly includes a second vertical rail 33, a third servo motor 34 and a third ball screw 35. The second vertical rail 33 is fixedly connected to the first moving block 31 so as to move up and down synchronously with the first moving block 31. The third servo motor 34 is fixedly mounted at the bottom of the inner cavity of the second vertical rail 33, and the third ball screw 35 is rotatably mounted in the inner cavity of the second vertical rail 33. The output end of the third servo motor 34 is connected to the lower end of the third ball screw 35, and the second moving block 36 is screwed on the third ball screw 35. Driven by the third servo motor 34, the second moving block 36 can move up and down relative to the third ball screw 35. The second moving block 36 is fixedly connected to the tool box 37 to push the tool box 37 up and down. The lifting mechanism adopts a structure in which at least two lifting assemblies are arranged in stages, which can effectively reduce the stroke and load of a single lifting assembly, so that the operation of a single lifting assembly is more stable and reliable, and is not easy to be overloaded or unbalanced.

[0071] Of course, it should be noted that in the embodiment of the present invention, the lifting mechanism may include three, four or even more lifting components arranged in stages. The specific arrangement can be referred to above and will not be repeated here. In addition, the lifting component may also be powered by a cylinder, an electric cylinder, a hydraulic cylinder or the like.

[0072] In addition, a connection portion 24 for connecting a safety rope may be provided on the safety seat. After the operator sits on the safety seat, the safety rope on the operator's body may be fixed to the connection portion 24 to further ensure his own life safety. The connection portion 24 may be a protrusion provided on the safety seat, or a hole, groove, ring or other structure on the safety seat.

[0073] The embodiment of the present invention further provides a tower climbing system, which includes a traction device and any of the above-mentioned safe tower climbing devices.

[0074] For reference Figure 2 As shown, the traction equipment may specifically include a winch 4 and a pulley block 6. The winch 4 is arranged on the ground, or on a fixed platform similar to the ground. The pulley block 6 is arranged on the communication tower 1, and the traction rope 5 of the winch 4 passes through the pulley block 6 and is connected to the safety tower climbing device.

[0075] In the embodiment of the present invention, the pulley block 6 may be a fixed pulley block. A horizontally extending support rod is provided on the communication tower 1, and a fixed pulley in the fixed pulley block is provided at the end of the support rod. Of course, the pulley block 6 may also be a movable pulley block, and its specific arrangement depends on actual needs, which will not be described here.

[0076] When the operator needs to climb the tower, he first needs to install the winch 4 on the ground near the communication tower 1, and then pre-limit the limit frame 21 on the safety tower climbing device to fit on the stepping rod 3 of the ladder 2 of the communication tower 1. That is, first put the limit frame 21 of the safety tower climbing device on the stepping rod 3, and drive the limit block 23 to extend to the bottom of the stepping rod 3 through the limit block driving member 22 to prevent the stepping rod 3 from escaping from the opening of the limit frame 21. Next, the operator passes the traction rope 5 of the winch 4 around the pulley block 6, and then connects the end of the traction rope 5 to the back plate 7 of the safety seat. At this time, the installation stage of the safety tower climbing device is completed.

[0077] After the installation stage of the safety tower climbing device is completed, the operator rotates the safety guardrail outward to open it and sits on the seat plate 8. After the safety guardrail is reset, the bolt driving ball screw 41 is turned so that the bolt driving ball screw 41 drives the bolt 42 to be inserted into the socket 43, thereby fixing the safety guardrail. At this time, the operator's riding stage is completed.

[0078] After the operator is seated, he controls the alternating tower climbing mechanism to move. The alternating tower climbing mechanism includes two telescopic limit component groups, and the two telescopic limit component groups each include two telescopic limit components. The two telescopic limit components are arranged horizontally symmetrically relative to the safety seat. One of the telescopic limit component groups is located above the other telescopic limit component group. For the convenience of naming, the telescopic limit components located above are temporarily referred to as the first telescopic limit components 9, and the telescopic limit components located below are temporarily referred to as the second telescopic limit components 10. When the first telescopic limit component 9 is started, the limit block driving member 22 on the first telescopic limit component 9 drives the limit block 23 to move to the side of the pedal 3, and then the limit frame driving member 46 drives the limit frame 21 to move upward, and the telescopic member 19 drives the limit frame 21 to retract to a position where it does not interfere with the climbing ladder 2.

[0079] At this time, on the first telescopic limit assembly 9, the first pump 17 of the sliding mechanism pumps the liquid medium in the upper liquid capsule 12 into the liquid tank 16, and the second pump 18 pumps the liquid medium in the liquid tank 16 into the lower liquid capsule 13. At this time, the sliding block 14 of the sliding mechanism is forced to move upward, and drives the telescopic member 19 to move up to the position of the upper step rod 3. The telescopic member 19 pushes the limit frame driving member 46 to extend, and the limit frame driving member 46 pushes the limit frame 21 to move downward, so that the limit frame 21 is mounted on the upper step rod 3. Then the limit block driving member 22 pushes the limit block 23 to move below the upper step rod 3.

[0080] Next, the second telescopic limit assembly 10 is started, and the second telescopic limit assembly 10 moves to the upper level pedal 3 corresponding to the second telescopic limit assembly 10 in the same manner as the second telescopic limit assembly 10. Then the winch 4 is started to pull the safety seat up a certain distance. In this process, in the first telescopic limit assembly 9 and the second telescopic limit assembly 10, the second pump 18 of the sliding mechanism pumps the liquid medium inside the lower liquid capsule 13 into the liquid tank 16, and the first pump 17 pumps the liquid medium inside the liquid tank 16 into the upper liquid capsule 12. At this time, the sliding block 14 of the sliding mechanism is forced to move upward and assist the safety seat in rising.

[0081] The process of descent is the reverse of the above process, which will not be described here.

[0082] When the operator needs to access the tools in the toolbox 37, the first servo motor 26 can be used to drive the first ball screw 27 to rotate, thereby causing the first ball screw 27 to drive the movable platform 28 to move out of the storage box 25. Then, the second servo motor 32 drives the second ball screw 30 to rotate, causing the first moving block 31 to drive the second vertical rail 33 and the toolbox 37 to move upward. Finally, the third servo motor 34 drives the third ball screw 35 to rotate, causing the second moving block 36 to drive the toolbox 37 to move upward until the toolbox 37 rises to a height that the operator can access. When the toolbox 37 is recovered, the above process is reversed, which will not be described here.

[0083] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

[0084] It should be noted that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as the scope of protection of the present invention. Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
