Description

Technical Field

[0001] This utility model relates to the field of power supply device technology, specifically to a follow-up power supply system and an overhead self-propelled vehicle system having the same. Background Technology

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

[0003] The power supply methods in related technologies are limited by the characteristics of high-altitude and long-distance movement, and generally have many technical pain points: On the one hand, the cable needs to be dragged along the long distance with the trolley, which is prone to damage to the insulation layer and breakage of the wire due to friction and pulling, which not only poses safety hazards, but also greatly increases the frequency and cost of equipment maintenance; on the other hand, traditional wiring methods are difficult to adapt to the needs of the trolley's flexible movement, and are prone to cable tangling, jamming or untimely follow-up, which seriously affects the trolley's operating accuracy and continuous operation efficiency.

[0004] Therefore, the follow-up power supply system in related technologies suffers from problems such as easy wear and tangling of cables. Utility Model Content

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a follow-up power supply system that can prevent cable tangling and reduce wear.

[0006] The follower-type power supply system of this utility model embodiment includes a drive rope and a cable assembly. The drive rope includes a first drive segment, which extends in the follower direction and is movable in the follower direction.

[0007] 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 mentioned below, where the following direction is the same as the direction of movement of the self-propelled vehicle.

[0008] The cable assembly includes a fixed cable fastening assembly, multiple follower cable fastening assemblies, and a cable. The cable has a first segment and fixed ends and follower ends respectively located at both ends of the first segment. The fixed cable fastening assembly is fixedly mounted on the drive rope and is connected to the follower end. That is, when the drive rope drives the fixed cable fastening assembly to move, the fixed cable fastening assembly can drive the follower end of the cable to move. At the same time, the follower end can be electrically connected to the electrical equipment to supply power to the electrical equipment. It can also control the movement of the drive rope to achieve the effect of controlling the follower end of the cable to follow the movement of the trolley.

[0009] Multiple follower-type cable fastening components are positioned on one side of the fixed cable fastening component in the following direction. These components are arranged sequentially along the following direction and slidably mounted on the drive rope. Each follower-type cable fastening component is connected to the first segment. The connections between these components and the first segment are spaced apart along the extension direction of the first segment. This spacing allows the first segment of the cable to be stored together when not in use. When in use, the first segment can be unfolded to follow the follower end, enabling it to move in real-time and providing real-time support for the electrical equipment. Furthermore, it prevents tangling and wear on the first segment, extending its service life.

[0010] Furthermore, the system's design, combining a fixed cable fastening assembly with multiple follower-type cable fastening assemblies, allows it to adapt to the needs of electrical equipment of varying lengths and movement ranges. As the movement range of the equipment increases, the power supply system can be easily expanded simply by increasing the length of the first cable segment and the number of follower-type cable fastening assemblies. Simultaneously, the system boasts high safety and stability; the tight cooperation between the fixed and follower-type cable fastening assemblies ensures the cable's stability during movement, effectively preventing safety hazards such as cable detachment or loosening.

Detailed Implementation

[0031] The embodiments of the present invention are described in detail below, examples of which are shown 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 following describes in detail the follow-up power supply system of the present invention.

[0033] The follow-up power supply system of this utility model embodiment 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] Multiple follower-type cable fastening components 6 are arranged on one side of the fixed cable fastening component 5 in the follower direction. The multiple follower-type cable fastening components 6 are arranged sequentially along the follower direction. The follower-type cable fastening components 6 are slidably mounted on the drive rope 1, and the follower-type cable fastening components 6 are connected to the first segment 2011. The connection points of the multiple follower-type cable fastening components 6 and the first segment 2011 are spaced apart in the extension direction of the first segment 2011. That is to say, there is a gap at the connection points of the multiple follower-type cable fastening components 6 and the first segment 2011, so that the first segment 2011 of the cable 201 can be stored together when not in use. When in use, the first segment 2011 of the cable 201 can be unfolded to move with the follower end 20112. On the one hand, it can make the first segment 2011 move with the follower end 20112 in real time, achieving the effect of real-time power supply to the equipment site. On the other hand, it can also avoid the problem of tangling and wear of the first segment 2011 of the cable 201, and extend the service life of the cable 201.

[0038] Furthermore, the design of the fixed cable fastening assembly 5 and multiple follower cable fastening assemblies 6 in combination with the drive rope 1 allows the system to adapt to the needs of electrical equipment with different lengths and movement ranges. When the movement range of the electrical equipment increases, the power supply system can be easily expanded simply by increasing the length of the first segment 2011 of the cable 201 and the number of follower cable fastening assemblies 6 accordingly. At the same time, the system also possesses high safety and stability. The tight cooperation between the fixed cable fastening assembly 5 and the follower cable fastening assemblies 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 this utility model embodiment can avoid the problems of wear and tangling of the cable 201.

[0040] In some embodiments, the follow-up power supply system of this utility model further includes a drive wheel set 3. The drive wheel set 3 includes a first wheel 301 and a second wheel 302 spaced apart in the follow-up direction. The drive rope 1 is wound around the first wheel 301 and the second wheel 302. At least one of the first wheel 301 and the second wheel 302 drives the drive rope 1 to move. That is, the first wheel 301 can drive the drive rope 1 to move, the second wheel 302 can drive the drive rope 1 to move, or the first wheel 301 and the second wheel 302 can drive the drive rope 1 to move simultaneously.

[0041] Meanwhile, the drive rope 1 also includes a second drive section 102, which extends in the following direction and is movable in the following direction; the first drive section 101 is located on one side of the drive wheel set 3, and the second drive section 102 is located on the other side of the drive wheel set 3.

[0042] Specifically, such as Figure 1 As shown, the first drive section 101 is the part of the drive rope 1 located on the lower side, and the second drive section 102 is the part of the drive rope 1 located on the upper side.

[0043] By setting up a drive wheel set 3 including a first wheel 301 and a second wheel 302, the movement of the drive rope 1 can be better controlled, thereby making it easier for the cable 201 to move with the electrical equipment.

[0044] In some embodiments, the follow-up power supply system of this utility model further includes a first drive rope tensioning component 4. The first drive rope tensioning component 4 includes a first pulley component 401 and a connecting rope 402. The first pulley component 401 is slidably disposed on the second drive section 102 and is connected to the second drive section 102 through the connecting rope 402.

[0045] By setting a first drive rope tensioning assembly 4 between the first drive segment 101 and the second drive segment 102, and a first pulley assembly 401 located on the upper side of the second drive segment 102, the first pulley assembly 401 can slide relative to the second drive segment 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 drive segment 101. Thus, without affecting the movement of the first drive segment 101 and the second drive segment 102, the gap between the first drive segment 101 and the second drive segment 102 can be avoided from being too large.

[0046] In some embodiments, such as Figure 2 and 3 As shown, the first pulley assembly 401 includes a first pulley 4011, a first pulley seat 4012, and a first connector 4013. The first pulley 4011 is slidably disposed on the second drive section 102. The first pulley 4011 is rotatably connected to the first pulley seat 4012. The first connector 4013 is connected to the first sliding seat and is connected to the first drive section 101 through a connecting rope 402.

[0047] like Figure 3 As shown, the first pulley seat 4012 has a U-shaped cross section and includes two oppositely arranged side plates. The first pulley 4011 is located between the two side plates and is connected to the two side plates through a shaft. A bearing can be provided between the first pulley 4011 and the shaft to facilitate better rotation of the first pulley 4011. At the same time, a groove is provided on the outer periphery of the first pulley 4011 to facilitate the first pulley 4011 being mounted on the second drive section 102.

[0048] It is understandable that the first connector 4013 and the first pulley seat 4012 are fixedly connected. This fixed connection ensures the stability of the first pulley assembly 401 structure. During the operation of the first drive rope tensioning assembly 4, the first pulley seat 4012 can reliably drive the first pulley 4011 and the first connector 4013 to move together. Moreover, the connection between the first connector 4013 and the connecting rope 402 can be detachable, for example, by means of clips or bolts. This design facilitates the quick separation of the first connector 4013 and the connecting rope 402 when maintenance or replacement of parts is required for the first drive rope tensioning assembly 4, improving maintenance efficiency. In addition, the connecting rope 402 is made of high-strength, wear-resistant materials, such as steel wire rope. Such materials can withstand large tensile forces, ensuring that they 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 to the first pulley seat 4012, one end of the first connecting joint 40132 is rotatably connected to the first connecting seat 40131, and one end of the second connecting joint 40133 is rotatably connected to the first connecting seat 40131.

[0050] like Figure 3 As shown, the first connecting seat 40131 has a U-shaped cross-section and includes two oppositely arranged side plates. A portion of the first connecting joint 40132 is located between the two side plates, and one end of the first connecting joint 40132 is connected to the two side plates through a shaft, while the other portion of the first connecting head is located outside the first connecting seat 40131. At the same time, one end of the second connecting joint 40133 is connected to the two side plates through a shaft, while the other portion of the second connecting head is located outside the first connecting seat 40131.

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

[0052] It is understandable that the connection between the two ends of the connecting rope 402 and the first connecting joint 40132 and the second connecting joint 40133 respectively forms a closed loop structure. This closed loop structure design can effectively reduce the probability of problems such as loosening or tangling of the connecting rope 402 during operation, and improve the reliability and stability of the entire 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 installation foundation 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 a certain extent, enabling it to better withstand various external forces generated during operation and ensuring that the first drive rope tensioning assembly 4 can work stably for a long time.

[0054] In some embodiments, such as Figure 4 As shown, the fixed cable fastening assembly 5 includes a first fixing component 501 and a second fixing component 502. The first fixing component 501 and the second fixing component 502 are rotatably connected. The first fixing component 501 is connected to the second drive section 102. The second fixing component 502 is connected to the follower end 20112.

[0055] It is understandable that the rotational connection between the first fixing component 501 and the second fixing component 502 allows the fixed cable fastening component 5 to flexibly adapt to the cable 201 fixing requirements at different angles and directions. During the operation of the follow-up power supply system, the relative position of the follower end 20112 and the second drive section 102 may change due to factors such as equipment movement and vibration. The rotational connection structure between the first fixing component 501 and the second fixing component 502 can adapt well to this change.

[0056] In some embodiments, such as Figure 4 and 5 As shown, the first fixing component 501 includes a first fixing plate 5011 and a second fixing plate 5012. A first gap 5013 is provided between the first fixing plate 5011 and the second fixing plate 5012. The first driving segment 101 passes through the first gap 5013. The first fixing plate 5011 and the second fixing plate 5012 are connected by a first fastener 5014.

[0057] The first fastener 5014 may use a bolt and nut such that the first fastener 5014 can adjust the size of the first gap 5013 between the first fixing plate 5011 and the second fixing plate 5012 to accommodate the first drive section 101 of different sizes.

[0058] The design of the first fixing plate 5011 and the second fixing plate 5012 effectively clamps the first drive section 101, preventing it from loosening or falling off during operation. The first fastener 5014 further enhances the stability of the first fixing component 501, ensuring a reliable connection between the first fixing component 501 and the second drive section 102. Simultaneously, this design facilitates the installation and removal of the first drive section 101, improving the maintenance efficiency of the entire servo power supply system.

[0059] In some embodiments, such as Figure 4 and 5 As shown, the second fixing component 502 includes a third fixing plate and a fourth fixing plate 5022. The third fixing plate 5021 is rotatably connected to the second fixing plate 5012. A second gap 5023 is provided between the third fixing plate 5021 and the fourth fixing plate 5022. The driving section passes through the second gap 5023. The third fixing plate 5021 and the fourth fixing plate 5022 are connected by a second fastener 5024.

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

[0061] Meanwhile, the rotational connection between the third fixing plate 5021 and the second fixing plate 5012 allows the second fixing component 502 to flexibly respond to changes in the position of the second drive section 102 and the cable 201.

[0062] Therefore, the third fixing plate 5021 and the fourth fixing plate 5022 cooperate with each other to firmly clamp the drive section, preventing it from shaking or shifting during operation. The second fastener 5024 enhances the reliability of the connection between the second fixing component 502 and the drive section, and this structure also facilitates the installation and removal of the drive section, helping to improve the ease of use and maintainability of the entire servo power supply system.

[0063] In some embodiments, such as Figure 5 As shown, the fourth fixing plate is located below the third fixing plate, and the fourth fixing plate is an arc-shaped plate.

[0064] Understandably, setting the fourth fixing plate as an arc-shaped plate allows for a better fit to the shape of cable 201, further enhancing the fixing effect on cable 201. At the same time, this fitting design effectively disperses the stress on the drive section, reducing localized stress concentration and thus lowering the risk of cable 201 being damaged during operation.

[0065] In some embodiments, the follower cable fastening assembly 6 includes a second pulley assembly 601 and a third fixing assembly 602. The second pulley assembly 601 is slidably disposed on the first drive section 101, and the third fixing assembly 602 is rotatably connected to the second pulley assembly 601 and connected to the first section 2011.

[0066] The design of the second pulley assembly 601 allows it to slide smoothly on the first drive section 101. When the drive rope 1 drives the follower end 20112 of the first section 2011 of the cable 201 to move through the fixed cable fastening assembly 5, the follower cable fastening assembly 6 will also drive the first section 2011 of the drive rope 1 to move, thereby causing the first section 2011 to unfold. This process can avoid the problem of wear and entanglement of the cable 201 of the first section 2011.

[0067] Meanwhile, this sliding connection not only reduces frictional resistance but also improves the flexibility of the entire assembly. The rotational connection between the third fixing assembly 602 and the second pulley assembly 601 further enhances the adaptability of the assembly, enabling it to adapt to changes in the relative position between the first drive section 101 and the first section 2011 of the cable 201. At the same time, this structural design ensures the stability of the follow-up cable fastening assembly 6 and 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 being rotatably connected to the second pulley seat 6012, and the second pulley 6011 being slidably disposed on the second drive section 102; the third fixing assembly 602 is rotatably connected to the second pulley seat 6012.

[0069] like Figure 6 and Figure 7 As shown, the cross-section of the second pulley seat 6012 is U-shaped, including two oppositely arranged side plates. The second pulley 6011 is located between the two side plates and is connected to the two side plates through a shaft. A bearing can be provided between the second pulley 6011 and the shaft to facilitate better rotation of the second pulley 6011. At the same time, a groove is provided on the outer periphery of the second pulley 6011 to facilitate the second pulley 6011 being mounted on the second drive section 102.

[0070] In some embodiments, the third fixing component 602 includes a fifth fixing plate 6021 and a sixth fixing plate 6022. The fifth fixing plate 6021 is rotatably connected to the second pulley seat 6012. A third gap 6023 is provided between the fifth fixing plate 6021 and the sixth fixing plate 6022. The first segment 2011 passes through the third gap 6023. The fifth fixing plate 6021 and the sixth fixing plate 6022 are connected by a third fastener 6024.

[0071] The third fastener 6024 can also be a bolt or nut. By adjusting the third fastener 6024, the size of the third gap 6023 between the fifth fixing plate 6021 and the sixth fixing plate 6022 can be changed, thus accommodating cables 201 of different sizes. At the same time, the clamping force between the fifth fixing plate 6021 and the sixth fixing plate 6022 can be adjusted according to actual needs, ensuring the fixing effect of the cable 201 while avoiding 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 its flexibility and reliability in practical applications.

[0072] Meanwhile, the rotatable connection between the third fixed clamp 5021 and the second fixed clamp 5012 allows for flexible responses to changes in the position of the second drive section 102 and the cable 201.

[0073] Therefore, the third fastener 6024 enhances the reliability of the connection between the third fixing component 602 and the cable 201. Moreover, this structure facilitates the installation and removal of the drive section, which helps to improve the ease of use and maintainability of the entire servo power supply system.

[0074] In some embodiments, such as Figure 7 As shown, the sixth fixing plate is located below the fifth fixing plate, and the sixth fixing plate is an arc-shaped plate.

[0075] Understandably, setting the sixth fixing plate as an arc-shaped plate allows for a better fit to the shape of cable 201, further enhancing the fixing effect on cable 201. At the same time, this fitting design effectively disperses the stress on the drive section, reducing localized stress concentration and thus lowering the risk of cable 201 being damaged during operation.

[0076] In some embodiments, the drive wheel assembly 3 further includes a first wheel seat 303 and a second wheel seat 304. The first wheel 301 is rotatably connected to the first wheel seat 303, and the first wheel seat 303 is fixedly installed. The second wheel 302 is rotatably connected to the second wheel seat 304, and the second wheel seat 304 is movable. That is, by adjusting the distance between the first wheel 301 and the second wheel 302, the tension of the drive rope 1 can be greatly adjusted.

[0077] Therefore, as Figure 1 As shown, the follow-up power supply system also includes a second drive rope tensioning assembly 7. The second drive rope tensioning assembly 7 includes a first tensioning wheel 701, a first tensioning rope 702 and a counterweight 703. One end of the first tensioning rope 702 is connected to the second wheel seat 304, and the other end of the first tensioning rope 702 is connected to the counterweight 703. The first tensioning rope 702 is wound around the first tensioning wheel 701.

[0078] By setting the second drive rope tensioning component 7, the second wheel seat 304 can be pulled, so that the distance between the first wheel 301 and the second wheel 302 is always within a reasonable range, and thus the tension of the drive rope 1 is always within a suitable range.

[0079] In some embodiments, the follow-up power supply system of this utility model further includes a cable fixing member 8, which is connected to a fixing end 20111 to fix the fixing end 20111 of the cable 201. At the same time, the cable 201 also includes a second segment 2012, one end of which is electrically connected to the fixing end 20111.

[0080] By setting the cable fixing component 8, the second segment 2012 of the cable 201, which does not need to move, can maintain a relatively fixed position. At the same time, the other end of the second segment is electrically connected to the power supply equipment to ensure that the power supply equipment can be powered.

[0081] This utility model also provides an overhead self-propelled vehicle system.

[0082] The overhead self-propelled vehicle system of this utility model embodiment includes a follow-up power supply system as described in the above embodiment; a walking cable 9 and a self-propelled vehicle 10, the self-propelled vehicle 10 being slidably mounted on the walking cable 9, and the self-propelled vehicle 10 having a power consumption terminal 11; the cable 201 also includes a third segment 2013, one end of the third segment 2013 being electrically connected to the drive segment, and the other end of the third segment 2013 being electrically connected to the power consumption terminal 11.

[0083] With the above settings, when the self-propelled vehicle 10 slides on the walking cable 9, the follow-up power supply system can move with the movement of the self-propelled vehicle 10, and the third section 2013 cable 201 can always maintain electrical connection with the power consumption end 11, thereby providing stable power supply to the power consumption end 11 of the self-propelled vehicle 10, ensuring that the power demand of the self-propelled vehicle 10 is met during operation, and ensuring that the overhead self-propelled vehicle system can operate normally.

[0084] In some embodiments, the overhead self-propelled vehicle system of this utility model further includes a protective rope 12, one end of which is connected to the fixed cable fastening assembly 5, and the length of the protective rope 12 is less than the length of the third segment 2013.

[0085] Understandably, the protective rope 12 serves a safety function during the operation of the self-propelled trolley 10. On the one hand, when the third segment 2013 breaks unexpectedly or other abnormal situations occur, the protective rope 12 can prevent the self-propelled trolley 10 from suddenly falling due to loss of power connection, effectively ensuring the safety of the operation of the self-propelled trolley 10, reducing the risk of accidents, and further improving the stability and reliability of the entire overhead self-propelled trolley system. On the other hand, the length of the protective rope 12 is less than the length of the third segment 2013, which ensures that the third segment 2013 is not pulled when the self-propelled trolley 10 is running, thereby preventing the third segment 2013 from being torn apart.
