Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power supply devices, in particular to a follow-up power supply system and an overhead self-propelled trolley system with the same. BACKGROUND

[0002] In high-altitude operation scenarios, self-propelled trolleys often need to move continuously in a large-span space of hundreds of meters, and stable power supply is a core requirement to ensure the normal operation of the equipment.

[0003] The power supply method in the related art is limited by the characteristics of long-distance movement at high altitudes, and there are many technical pain points: on the one hand, the cable needs to be dragged along with the trolley for a long distance, which is easy to cause damage to the insulation layer and break the wire due to friction and pulling, not only posing a safety hazard, but also greatly increasing the equipment maintenance frequency and cost; on the other hand, the traditional wiring method is difficult to adapt to the flexible movement of the trolley, and is easy to cause cable winding, jamming or follow-up delay, which seriously affects the operation accuracy and continuous operation efficiency of the trolley.

[0004] Therefore, the follow-up power supply system in the related art has the problems of easy cable wear and winding. SUMMARY

[0005] The present application aims to at least solve one of the technical problems in the related art. To this end, an embodiment of the present application proposes a follow-up power supply system that can avoid cable winding and reduce wear.

[0007] It can be understood that the follow-up direction can be understood as the moving direction of the electric device, for example, the self-propelled trolley mentioned below, and the follow-up direction is the same as the moving direction of the self-propelled trolley.

[0008] The cable assembly includes a fixed cable fastening assembly, a plurality of follow-up cable fastening assemblies, and a cable. The cable has a first segment and a fixed end and a follow-up end arranged at both ends of the first segment, respectively. The fixed cable fastening assembly is fixedly arranged on the drive rope, and the fixed cable fastening assembly is connected to the follow-up end. That is, when the drive rope moves the fixed cable fastening assembly, the fixed cable fastening assembly can move the follow-up end of the cable, and the follow-up end can be electrically connected to the electric device to supply power to the electric device. At the same time, by controlling the movement of the drive line, the effect of controlling the follow-up end of the cable to move with the trolley can be achieved.

[0010] In addition, due to the design of the driving rope fixed cable fastening assembly and the plurality of follow-up cable fastening assemblies, the system can adapt to the power supply requirements of electrical equipment with different lengths and movement ranges.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is in conjunction with the appendix Figures 1-7 The follow-up power supply system of the present invention will be described in detail.

[0033] The follow-up power supply system of this invention includes a drive rope 1 and a cable assembly 2.

[0034] like Figure 1 As shown, the drive rope 1 includes a first drive segment 101, which extends in the following direction and is movable in the following direction.

[0035] It is understandable that the following direction can be understood as the direction of movement of the electrical equipment, such as the self-propelled vehicle 10 mentioned below, whose following direction is the same as the direction of movement of the self-propelled vehicle 10.

[0036] The cable assembly 2 includes a fixed cable fastening assembly 5, multiple follower cable fastening assemblies 6, and a cable 201. The cable 201 has a first segment 2011 and fixed ends 20111 and follower ends 20112 respectively located at both ends of the first segment 2011. The fixed cable fastening assembly 5 is fixedly mounted on the drive rope 1 and is connected to the follower ends 20112. That is, when the drive rope 1 drives the fixed cable fastening assembly 5 to move, the fixed cable fastening assembly 5 can drive the follower ends 20112 of the cable 201 to move. At the same time, the follower ends 20112 can be electrically connected to the electrical equipment to supply power to the electrical equipment. It can also control the follower ends 20112 of the cable 201 to follow the trolley by controlling the movement of the drive rope.

[0037] A plurality of follow-up cable fastening assemblies 6 are arranged on one side of the fixed cable fastening assembly 5 in the follow-up direction, and the plurality of follow-up cable fastening assemblies 6 are arranged in sequence along the follow-up direction. The follow-up cable fastening assembly 6 is slidably arranged on the driving rope 1, and the follow-up cable fastening assembly 6 is connected to the first section 2011. The connection positions of the plurality of follow-up cable fastening assemblies 6 and the first section 2011 are arranged at intervals in the extension direction of the first section 2011, that is, the connection positions of the plurality of follow-up cable fastening assemblies 6 and the first section 2011 are arranged at intervals, so that the first section 2011 of the cable 201 can be stored together when not in use. When the first section 2011 of the cable 201 is in use, it can be unfolded to move with the follow-up end 20112. On the one hand, the first section 2011 can move in real time with the follow-up end 20112, achieving the effect of real-time power supply for the electrical equipment site. On the other hand, it can also avoid the problem of entanglement and wear of the first section 2011 of the cable 201, and can prolong the service life of the cable 201.

[0038] In addition, due to the design of the driving rope 1 fixed cable fastening assembly 5 and the plurality of follow-up cable fastening assemblies 6, the system can adapt to the power supply requirements of electrical equipment of different lengths and movement ranges. When the movement range of the electrical equipment increases, the length of the first section 2011 of the cable 201 and the number of follow-up cable fastening assemblies 6 can be increased accordingly, so that the power supply system can be easily expanded. At the same time, the system also has high safety and stability. The close cooperation of the fixed cable fastening assembly 5 and the follow-up cable fastening assembly 6 ensures the stability of the cable 201 during movement, effectively preventing safety hazards such as cable 201 falling off or loosening.

[0039] Therefore, the follow-up power supply system of the embodiment of the present application can avoid the problem of wear and entanglement of the cable 201.

[0040] In some embodiments, the follow-up power supply system of the embodiment of the present application further comprises a driving wheel set 3, the driving wheel set 3 comprising a first wheel 301 and a second wheel 302 arranged at intervals in the follow-up direction, the driving rope 1 being wound around the first wheel 301 and the second wheel 302, at least one of the first wheel 301 and the second wheel 302 driving the driving rope 1 to move, that is, the first wheel 301 can drive the driving rope 1 to move, the second wheel 302 can drive the driving rope 1 to move, or the first wheel 301 and the second wheel 302 can simultaneously drive the driving rope 1 to move.

[0041] At the same time, the driving rope 1 further comprises a second driving section 102, the second driving section 102 being arranged in extension in the follow-up direction and being movable in the follow-up direction; the first driving section 101 is arranged on one side of the driving wheel set 3, and the second driving section 102 is arranged on the other side of the driving wheel set 3.

[0042] Specifically, as shown inFigure 1 As shown in the drawings, the first driving section 101 is the part where the driving rope 1 is located at the lower side, and the second driving section 102 is the part where the driving rope 1 is located at the upper side.

[0043] By setting the driving wheel set 3 including the first wheel 301 and the second wheel 302, the movement of the driving rope 1 can be better controlled, and the cable 201 can be facilitated to move with the electrical equipment.

[0044] In some embodiments, the servo power supply system further comprises a first driving rope tensioning assembly 4, the first driving rope tensioning assembly 4 comprising a first pulley assembly 401 and a connecting rope 402, the first pulley assembly 401 being slidingly arranged on the second driving section 102, and the first pulley assembly 401 being connected to the second driving section 102 through the connecting rope 402.

[0045] By setting the first driving rope tensioning assembly 4 between the first driving section 101 and the second driving section 102, the first pulley assembly 401 is arranged on the second driving section 102 at the upper side, and the first pulley assembly 401 can slide relative to the second driving section 102, one end of the connecting rope 402 is connected to the first pulley assembly 401, and the other end of the connecting rope 402 is connected to the first driving section 101, thereby avoiding the distance between the first driving section 101 and the second driving section 102 being too large without affecting the movement of the first driving section 101 and the second driving section 102.

[0046] In some embodiments, as shown in Figure 2 and 3 The first pulley assembly 401 comprises a first pulley 4011, a first pulley seat 4012 and a first connector 4013, the first pulley 4011 being slidingly arranged on the second driving section 102, the first pulley 4011 being rotatably connected to the first pulley seat 4012, the first connector 4013 being connected to the first sliding seat, and the first connector 4013 being connected to the first driving section 101 through the connecting rope 402.

[0047] As shown in Figure 3 The cross section of the first pulley seat 4012 is U-shaped, comprising two oppositely arranged side plates, the first pulley 4011 being arranged between the two side plates, and the first pulley 4011 being connected to the two side plates through a shaft, and a bearing can be arranged between the first pulley 4011 and the shaft to facilitate better rotation of the first pulley 4011, and a groove is arranged on the outer periphery of the first pulley 4011 to facilitate the arrangement of the first pulley 4011 on the second driving section 102.

[0048] It can be understood that the first connector 4013 is fixedly connected with the first pulley seat 4012, and the fixed connection ensures the stability of the structure of the first pulley assembly 401. During the operation of the first driving rope tensioning assembly 4, the first pulley seat 4012 can reliably drive the first pulley 4011 and the first connector 4013 to move together. In addition, the connection between the first connector 4013 and the connecting rope 402 can be detachable, for example, through buckling or bolt connection. Such a design facilitates the separation of the first connector 4013 from the connecting rope 402 when maintenance or replacement of the first driving rope tensioning assembly 4 is required, thereby improving the maintenance efficiency. In addition, the connecting rope 402 is made of high-strength and wear-resistant material, such as a steel wire rope. Such material can withstand a large tensile force and will not easily break during long-term use, thereby ensuring the normal operation of the follow-up power supply system.

[0049] In some embodiments, the first connector 4013 includes a first connecting seat 40131, a first connecting joint 40132, and a second connecting joint 40133. The first connecting seat 40131 is connected with the first pulley seat 4012. One end of the first connecting joint 40132 is rotatably connected with the first connecting seat 40131, and one end of the second connecting joint 40133 is rotatably connected with the first connecting seat 40131.

[0050] As shown in Figure 3 , the first connecting seat 40131 has a U-shaped cross section and includes two oppositely arranged side plates. Part of the first connecting joint 40132 is arranged between the two side plates, and one end of the first connecting joint 40132 is connected with the two side plates through a shaft body. The other part of the first connecting joint is arranged outside the first connecting seat 40131. Meanwhile, one end of the second connecting joint 40133 is connected with the two side plates through a shaft body, and the other part of the second connecting joint is arranged outside the first connecting seat 40131.

[0051] The first driving rope tensioning assembly 4 further includes a steel wire rope clamp 403. The rope body of the connecting rope 402 is connected with the first driving section 101 through the steel wire rope clamp 403. One end of the connecting rope 402 is connected with the other end of the first connecting joint 40132, and the other end of the connecting rope 402 is connected with the other end of the second connecting joint 40133. That is, the connecting rope 402 passes through the connection between the steel wire rope clamp 403 and the first driving section 101, so that one end of the connecting rope 402 is connected with the other end of the first connecting joint 40132, and the other end of the connecting rope 402 is connected with the other end of the second connecting joint 40133.

[0052] It can be understood that the connection mode of connecting the two ends of the connecting rope 402 with the first connecting joint 40132 and the second connecting joint 40133 respectively forms a closed loop structure. The design of the closed loop structure can effectively reduce the probability of problems such as loosening and winding of the connecting rope 402 during operation, and improve the reliability and stability of the operation of the whole follow-up power supply system.

[0053] In addition, the first connecting seat 40131 adopts a U-shaped cross-section design, which not only provides a stable mounting basis for the first connecting joint 40132 and the second connecting joint 40133, but also enhances the overall structural strength of the first connector 4013 to some extent, so that it can better withstand various external forces generated during operation, and ensure that the first driving rope tensioning assembly 4 can work stably for a long time.

[0054] In some embodiments, as shown in Figure 4 The fixed cable fastening assembly 5 includes a first fixed assembly 501 and a second fixed assembly 502, and the first fixed assembly 501 is rotatably connected with the second fixed assembly 502; the first fixed assembly 501 is connected with the second driving section 102; and the second fixed assembly 502 is connected with the follow-up end 20112.

[0055] It can be understood that the rotatable connection between the first fixed assembly 501 and the second fixed assembly 502 enables the fixed cable fastening assembly 5 to flexibly adapt to the cable 201 fixing requirements of different angles and directions. During the operation of the follow-up power supply system, the relative position of the follow-up end 20112 and the second driving section 102 may change due to factors such as movement and vibration of the equipment, and the rotatable connection structure of the first fixed assembly 501 and the second fixed assembly 502 can well adapt to such changes.

[0056] In some embodiments, as shown in Figure 4 and 5 The first fixed assembly 501 includes a first fixed clamping plate 5011 and a second fixed clamping plate 5012, and a first gap 5013 is arranged between the first fixed clamping plate 5011 and the second fixed clamping plate 5012. The first driving section 101 passes through the first gap 5013, and the first fixed clamping plate 5011 and the second fixed clamping plate 5012 are connected by a first fastener 5014.

[0057] The first fastener 5014 can be a bolt and a nut, so that the first fastener 5014 can adjust the size of the first gap 5013 between the first fixed clamping plate 5011 and the second fixed clamping plate 5012 to adapt to first driving sections 101 of different sizes.

[0058] The design of the first and second fixed clamping plates 5011 and 5012 can effectively clamp the first driving section 101, preventing it from loosening or falling off during operation. The arrangement of the first fastener 5014 further enhances the stability of the first fixed assembly 501, ensuring reliable connection between the first fixed assembly 501 and the second driving section 102. At the same time, this design also facilitates the installation and removal of the first driving section 101, improving the maintenance efficiency of the entire follow-up power supply system.

[0059] In some embodiments, as shown in Figure 4 and 5 The second fixed assembly 502 includes three fixed clamping plates and a fourth fixed clamping plate 5022, and the third fixed clamping plate 5021 is rotationally connected to the second fixed clamping plate 5012. A second gap 5023 is provided between the third and fourth fixed clamping plates 5021 and 5022, through which the driving section passes, and the third and fourth fixed clamping plates 5021 and 5022 are connected by a second fastener 5024.

[0060] The second fastener 5024 can also be a bolt and nut, and by adjusting the second fastener 5024, the size of the second gap 5023 between the third and fourth fixed clamping plates 5021 and 5022 can be changed, thereby accommodating cables 201 of different sizes.

[0061] Meanwhile, the rotational connection of the third fixed clamping plate 5021 to the second fixed clamping plate 5012 allows the second fixed assembly 502 to respond flexibly when facing changes in the position of the second driving section 102 and the cable 201.

[0062] Thus, the third and fourth fixed clamping plates 5021 and 5022 cooperate to securely clamp the driving section, preventing it from shaking or shifting during operation. The arrangement of the second fastener 5024 enhances the reliability of the connection between the second fixed assembly 502 and the driving section, and this structure also facilitates the installation and removal of the driving section, contributing to improved convenience and maintainability of the entire follow-up power supply system.

[0063] In some embodiments, as shown in Figure 5 The fourth fixed clamping plate is arranged below the third fixed clamping plate and is an arc-shaped plate.

[0064] It can be understood that arranging the fourth fixed clamping plate as an arc-shaped plate allows it to better conform to the shape of the cable 201, further enhancing the fixing effect on the cable 201. At the same time, this conforming design can effectively distribute the stress received by the driving section, reducing local stress concentration and thus reducing the risk of damage to the cable 201 during operation.

[0065] In some embodiments, the second pulley assembly 601 is slidably arranged on the first driving section 101, and the third fixed assembly 602 is rotatably connected with the second pulley assembly 601, and the third fixed assembly 602 is connected with the first section 2011.

[0066] The design of the second pulley assembly 601 enables it to smoothly slide on the first driving section 101. When the driving rope 1 moves the movable end 20112 of the first section 2011 of the cable 201 through the fixed cable fastening assembly 5, the driven cable fastening assembly 6 also moves the first section 2011 of the driving rope 1, thereby causing the first section 2011 to be deployed. This process can avoid the problem of wear and tear of the cable 201 of the first section 2011.

[0067] Meanwhile, this sliding connection method not only reduces the frictional resistance, but also improves the flexibility of the entire assembly. The rotatable connection of the third fixed assembly 602 with the second pulley assembly 601 further enhances the adaptability of the assembly, enabling it to adapt to the relative position changes between the first driving section 101 and the first section 2011 of the cable 201. At the same time, this structural design not only ensures the stability of the driven cable fastening assembly 6, but also improves its convenience and reliability during use.

[0068] In some embodiments, the second pulley assembly 601 includes a second pulley 6011 and a second pulley seat 6012, the second pulley 6011 is rotatably connected with the second pulley seat 6012, and the second pulley 6011 is slidably arranged on the second driving section 102; the third fixed assembly 602 is rotatably connected with the second pulley seat 6012.

[0069] As shown in Figure 6 and Figure 7 , the cross section of the second pulley seat 6012 is U-shaped, including two oppositely arranged side plates, the second pulley 6011 is arranged between the two side plates, and the second pulley 6011 is connected with the two side plates through a shaft body, and a bearing can be arranged between the second pulley 6011 and the shaft body to facilitate better rotation of the second pulley 6011. Meanwhile, a groove is provided on the outer periphery of the second pulley 6011 to facilitate the arrangement of the second pulley 6011 on the second driving section 102.

[0070] In some embodiments, the third fixed assembly 602 includes a fifth fixed clamping plate 6021 and a sixth fixed clamping plate 6022, the fifth fixed clamping plate 6021 is rotatably connected with the second pulley seat 6012; a third gap 6023 is provided between the fifth fixed clamping plate 6021 and the sixth fixed clamping plate 6022, the first section 2011 passes through the third gap 6023, and the fifth fixed clamping plate 6021 and the sixth fixed clamping plate 6022 are connected through a third fastener 6024.

[0071] The third fastener 6024 can also adopt a bolt and a nut. By adjusting the third fastener 6024, the size of the third gap 6023 between the fifth fixed clamping plate 6021 and the sixth fixed clamping plate 6022 can be changed, so as to adapt to cables 201 of different sizes. At the same time, the clamping force between the fifth fixed clamping plate 6021 and the sixth fixed clamping plate 6022 can be adjusted according to actual needs, which not only ensures the fixing effect of the cable 201, but also avoids damage to the cable 201 due to excessive clamping force. This design not only improves the stability of the follow-up power supply system, but also enhances the flexibility and reliability in actual application.

[0072] At the same time, the third fixed clamping plate 5021 is rotationally connected with the second fixed clamping plate 5012, which can also flexibly cope with the position changes of the second driving section 102 and the cable 201.

[0073] Therefore, the setting of the third fastener 6024 enhances the reliability of the connection between the third fixed assembly 602 and the cable 201, and this structure also facilitates the installation and disassembly operation of the driving section, which helps to improve the use convenience and maintainability of the entire follow-up power supply system.

[0074] In some embodiments, as shown in Figure 7 The sixth fixed clamping plate is arranged below the fifth fixed clamping plate, and the sixth fixed clamping plate is an arc-shaped plate.

[0075] It can be understood that the sixth fixed clamping plate is arranged as an arc-shaped plate, which can better fit the shape of the cable 201 and further enhance the fixing effect of the cable 201. At the same time, this fitting design can effectively disperse the stress received by the driving section and reduce local stress concentration, thereby reducing the risk of damage to the cable 201 during operation.
