Description

Technical Field

[0001] This invention relates to the technical field of intelligent cable trays, specifically to an intelligent large-span cable tray collapse active compensator with folding angle allowance and its compensation method. Background Technology

[0002] Cable trays, as a crucial cable support and laying facility, play an indispensable role in various fields such as power and communications. They not only provide stable support for cables, ensuring their safety and stability during laying, but also effectively prevent damage from external environmental factors, such as mechanical damage and corrosion, thereby extending the cable's service life. Furthermore, cable trays allow for a neater and more organized cable layout, facilitating subsequent management and maintenance, and improving the overall operational efficiency of the cable system.

[0003] For long-span cable trays, intelligent modules are usually integrated for monitoring, forming intelligent cable trays. Due to the large span and long dimensions, the area prone to failure and potential hazards is wider. Therefore, long-span cable trays are mostly intelligent cable trays. Intelligent cable trays are equipped with sensors and monitoring systems, so they can monitor the operating status of the cables in real time, including temperature, humidity, and current, and realize remote monitoring and management, timely detection and handling of potential problems, and improve the reliability and safety of the cable system.

[0004] However, large-span intelligent cable trays face many challenges during actual installation, one of the most prominent problems being the collapse of the cable trays.

[0005] Due to their large span, cable trays are prone to collapse. This collapse is mainly caused by the combined effects of the cable tray's own weight, the gravity of the cables after installation, and external environmental factors (such as wind and temperature changes). To mitigate this problem, appropriate compensators are often installed during the installation of cable trays.

[0006] However, most existing cable tray compensators employ a passive compensation method, meaning they only compensate when the cable tray is subjected to tensile or compressive forces. This passive compensation method has significant limitations; it is difficult to actively retract and cannot effectively and promptly address cable tray deformation. For large-span cable trays, a certain degree of longitudinal offset is likely to occur after installation, potentially posing a significant threat to the overall stability of the tray. Moreover, for existing compensators, this longitudinal offset factor may reduce their ability to compensate for cable tray expansion and contraction. In practical applications, the feasibility and reliability of such compensators need further improvement. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent large-span cable tray collapse active compensator with folding angle allowance and its compensation method, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An intelligent large-span cable tray collapse active compensator with folding angle allowance is installed between two cable trays and includes two sets of frame structures.

[0010] The framework structure includes:

[0011] The first frame and the second frame are rotatably connected by a shaft, and the first frame is fixedly connected to the cable tray.

[0012] A first horizontal arm is provided between the first frame and the second frame, and a second horizontal arm is fixed to the first horizontal arm. A horizontal bar is provided on the first horizontal arm, and two symmetrically arranged columnar springs are sleeved on the outer periphery of the horizontal bar.

[0013] Two first sliders are slidably mounted on the first cross arm. The first sliders are also slidably connected to the cross bar, and the head end of the cylindrical spring is connected to the first slider.

[0014] Two sliding plates are slidably mounted on the second cross arm. A second slider is provided on the sliding plate and is slidably connected to the cross bar. The tail end of the cylindrical spring is connected to the second slider.

[0015] Among them, a follower mechanism is provided between the shaft and the sliding plate. When the first frame and the second frame rotate relative to each other, the follower mechanism can drive the sliding plate to slide on the second cross arm, causing the columnar spring to deform.

[0016] As a further aspect of the present invention: the first frame has a protrusion at one end away from the cable tray, and the second frame has an arc-shaped recess at one end facing the first frame. The protrusion extends into the arc-shaped recess, and a gap is reserved between the two. The shaft is fixed to the protrusion, and the second frame is rotatably connected to the shaft.

[0017] As a further embodiment of the present invention: a guide rail is provided on the inner wall of the second frame, and the follow-up mechanism includes:

[0018] A movable seat, which is slidably fitted into the guide rail;

[0019] A deflection drive assembly connects the shaft and the movable seat. When the first frame and the second frame rotate relative to each other, the deflection drive assembly can drive the movable seat to slide within the guide rail.

[0020] A driven component is disposed on the second cross arm. When the movable seat slides within the guide rail, the driven component is triggered and can cause the sliding plate to slide on the second cross arm.

[0021] As a further embodiment of the present invention: the deflection drive assembly includes a drive arm fixed to the shaft, the drive arm having a groove along its own length direction, and the movable seat having a first column provided through a first connecting arm, the first column being adapted to the groove, and passing through the groove and slidably connected to the drive arm.

[0022] As a further embodiment of the present invention: the driven component includes a driven plate movably disposed at the bottom of the second cross arm via a guide member, and a transmission member is provided between the driven plate and the movable seat. When the movable seat slides within the guide rail, it can drive the driven plate to move toward or away from the second cross arm via the transmission member.

[0023] As a further embodiment of the present invention: the length direction of the driven plate is parallel to the axial direction of the crossbar, and the guide includes two columns slidably disposed on the second crossbar and perpendicular to the second crossbar. The first ends of the two columns are fixed to the driven plate, and the tail ends are each connected to the sliding plate through a set of sliding fittings.

[0024] As a further embodiment of the present invention: the transmission component includes a second column fixed to the movable seat via a second connecting arm, and the driven plate is provided with a strip-shaped through groove adapted to the second column along its own direction, the second column passing through the strip-shaped through groove and being slidably connected to the driven plate;

[0025] The second column has a frustum at one end away from the second connecting arm. The diameter of the frustum is larger than the diameter of the second column, and the frustum abuts against the driven plate.

[0026] As a further embodiment of the present invention: the sliding mating component includes a transmission plate fixedly installed on the side of the sliding plate and a follower arm fixed to the end of the column away from the driven plate. The follower arm is fixedly provided with a protrusion at the end away from the column, and the transmission plate is provided with an inclined through groove adapted to the protrusion.

[0027] The protruding post extends into the inclined through groove and is slidably connected to the transmission plate. When the driven plate moves away from the second cross arm, the protruding post slides along the strip through groove and can cause the transmission plate to drive the sliding plate to slide towards the middle position of the second cross arm.

[0028] A method for compensating intelligent long-span cable trays using the active compensator, wherein when the cable tray extends or retracts along its own length, the first frame transmits the extension force to the second frame through a shaft, and the first slider slides on the crossbar, causing the cylindrical spring to deform.

[0029] When the cable tray shifts longitudinally, the first frame and the second frame rotate relative to each other through the shaft, causing the follower mechanism to drive the sliding plate to slide the second slider on the crossbar, and the cylindrical spring deforms.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The present invention provides a first frame and a second frame between two sections of cable tray, and the first frame and the second frame are rotatably connected by a shaft and have a rotational allowance. When there is a length-direction expansion and contraction of a long-span cable tray, the shaft is used to transmit tensile or expansion forces, causing the cylindrical spring to deform.

[0032] When there is longitudinal offset in a long-span cable tray, the shaft can cause the sliding plate to change displacement through the follower mechanism, which also causes the column spring to deform. The column spring can automatically elastically recover according to the actual extension and longitudinal offset, realizing an active compensation function with automatic retraction effect.

[0033] This active compensation method for long-span cable trays avoids the adverse effects of longitudinal offset on the cable tray's ability to compensate for expansion and contraction along its length. Compared to passive compensation methods, it effectively ensures the stability of long-span cable trays, improves their ability to adapt to different environmental conditions, and ensures their safe and stable operation under various complex working conditions, providing reliable protection for cable laying and maintenance.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0050] Please see Figures 1-13 In this embodiment of the invention, an intelligent large-span cable tray collapse active compensator with folding angle allowance is installed between two cable trays 1 and includes two sets of frame structures.

[0051] The framework structure includes:

[0052] The first frame 2 and the second frame 3 are rotatably connected by a shaft 11, and the first frame 2 is fixedly connected to the cable tray 1;

[0053] A first horizontal arm 5 and a second horizontal arm 8 fixed to the first horizontal arm 5 are provided between the first frame 2 and the second frame 3. A horizontal bar 6 is provided on the first horizontal arm 5, and two symmetrically arranged columnar springs 7 are sleeved on the outer periphery of the horizontal bar 6.

[0054] Two first sliders 9 are slidably mounted on the first horizontal arm 5. The first sliders 9 are also slidably connected to the horizontal bar 6, and the head end of the cylindrical spring 7 is connected to the first sliders 9.

[0055] Two sliding plates 19 are slidably mounted on the second cross arm 8. A second slider 10 is provided on the sliding plate 19 and is slidably connected to the cross bar 6. The tail end of the cylindrical spring 7 is connected to the second slider 10.

[0056] Among them, a follower mechanism is provided between the shaft 11 and the sliding plate 19. When the first frame 2 and the second frame 3 rotate relative to each other, the follower mechanism can drive the sliding plate 19 to slide on the second cross arm 8, so that the column spring 7 is deformed.

[0057] Furthermore, a fixing strip 4 is provided on each side of the first frame 2. The fixing strip 4 has a through-hole that matches the hole on the cable tray 1. In actual construction, the first frame 2 is aligned with the end of the cable tray 1, and the through-hole on the fixing strip 4 is aligned with the hole on the cable tray 1. Then, it is fixed with bolts to complete the fixed connection between the first frame 2 and the cable tray 1. After the compensator is installed, the cover plate of the cable tray 1 is installed.

[0058] Please refer to it again. Figure 10 The first frame 2 has a protrusion 201 at one end away from the cable tray 1, and the second frame 3 has an arc-shaped recess 301 at one end facing the first frame 2. The protrusion 201 extends into the arc-shaped recess 301, and a gap is reserved between the two. The shaft 11 is fixed to the protrusion 201, and the second frame 3 is rotatably connected to the shaft 11.

[0059] The gap between the protrusion 201 and the arc-shaped recess 301 provides a bending angle allowance between the first frame 2 and the second frame 3. Therefore, when a long-span cable tray is laid and longitudinal displacement occurs due to gravity and external environmental factors, the first frame 2 and the second frame 3 can rotate relative to each other through the formed bending angle allowance. That is, the shaft 11 rotates relative to the second frame 3, and the shaft 11 drives the follower mechanism to move. The follower mechanism can drive the sliding plate 19 to slide on the second cross arm 8. Correspondingly, the sliding plate 19 drives the second slider 10 to slide on the cross bar 6, causing the column spring 7 to deform. In addition, when the long-span cable tray undergoes length-direction expansion and contraction, the first frame 2 can generate a tensile or extensile force on the second frame 3 through the shaft 11. Correspondingly, the first slider 9 slides on the cross bar 6, also causing the column spring 7 to deform.

[0060] Therefore, this invention, by setting a first frame 2 and a second frame 3 between two cable tray sections 1, and connecting the first frame 2 and the second frame 3 rotatably via a shaft 11 with a angular allowance, allows the shaft 11 to transmit tension or extension force when the long-span cable tray experiences length-direction expansion and contraction, causing the cylindrical spring 7 to deform. When the long-span cable tray experiences longitudinal offset, the shaft 11 can cause the sliding plate 19 to shift through a follower mechanism, similarly causing the cylindrical spring 7 to deform. The cylindrical spring 7 can automatically elastically recover according to the actual expansion and contraction and longitudinal offset, realizing an active compensation function with automatic retraction effect. This avoids the adverse effects of longitudinal offset on the cable tray's length-direction expansion and contraction compensation capability. Compared to passive compensation methods, this provides effective protection for the stability of long-span cable trays, improves the cable tray's ability to adapt to different environmental conditions, ensures the cable tray can operate safely and stably under various complex working conditions, and provides reliable protection for cable laying and maintenance.

[0061] Please refer to it again. Figure 10 and Figure 11 The inner wall of the second frame 3 is provided with a guide rail 12, and the follow-up mechanism includes:

[0062] Movable seat 13, which is slidably fitted into the guide rail 12;

[0063] A deflection drive assembly connects the shaft 11 and the movable seat 13. When the first frame 2 and the second frame 3 rotate relative to each other, the deflection drive assembly can drive the movable seat 13 to slide within the guide rail 12.

[0064] The driven component is disposed on the second horizontal arm 8. When the movable seat 13 slides in the guide rail 12, the driven component is triggered and can cause the sliding plate 19 to slide on the second horizontal arm 8.

[0065] The deflection drive assembly includes a drive arm 18 fixed to the shaft 11. The drive arm 18 has a sliding groove along its own length direction. The movable seat 13 is provided with a first column 16 through a first connecting arm 14. The first column 16 is adapted to the sliding groove, passes through the sliding groove, and is slidably connected to the drive arm 18.

[0066] When a long-span cable tray experiences longitudinal displacement, the first frame 2 and the second frame 3 will rotate relative to each other via the shaft 11. The shaft 11 then drives the drive arm 18 to deflect relative to the second frame 3. The drive arm 18 slides with the first column 16. The drive arm 18, through the first column 16 and the first connecting arm 14, drives the movable seat 13 to slide towards the bottom of the second frame 3 in the guide rail 12. Thus, the movable seat 13 can drive the driven component to move, causing the driven component to cause the sliding plate 19 to slide towards the middle of the second horizontal arm 8. Correspondingly, the second slider 10 slides on the crossbar 6, and the columnar spring 7 deforms, achieving automatic compensation for the longitudinal displacement of the long-span cable tray.

[0067] Please refer to it again. Figure 12 and Figure 13 The driven component includes a driven plate 22 movably mounted at the bottom of the second cross arm 8 via a guide member. A transmission member is provided between the driven plate 22 and the movable seat 13. When the movable seat 13 slides within the guide rail 12, it can drive the driven plate 22 to move toward or away from the second cross arm 8 via the transmission member. The length direction of the driven plate 22 is parallel to the axial direction of the cross bar 6. The guide member includes two columns 21 slidably mounted on the second cross arm 8 and perpendicular to the second cross arm 8. The first ends of the two columns 21 are fixed to the driven plate 22, and the tail ends are each connected to the sliding plate 19 via a set of sliding fittings.

[0068] Furthermore, when the long-span cable tray experiences longitudinal displacement, under the sliding engagement of the drive arm 18 and the first column 16, the movable seat 13 slides in the guide rail 12 toward the bottom of the second frame 3. Correspondingly, the column 21 guides the driven plate 22, and the movable seat 13 can drive the driven plate 22 away from the second cross arm 8 through the transmission component. Thus, the column 21 slides relative to the second cross arm 8, and the column 21 causes the sliding plate 19 to slide toward the middle part of the second cross arm 8 through the sliding engagement component. The second slider 10 moves synchronously with the sliding plate 19, causing the column spring 7 to deform, thereby achieving the function of compensating for the longitudinal displacement.

[0069] Please refer to it again. Figure 8The transmission component includes a second column 17 fixed to the movable seat 13 via a second connecting arm 15. The driven plate 22 has a strip-shaped through groove 2201 adapted to the second column 17 along its own direction. The second column 17 passes through the strip-shaped through groove 2201 and is slidably connected to the driven plate 22. The end of the second column 17 away from the second connecting arm 15 is provided with a frustum 1701. The diameter of the frustum 1701 is larger than the diameter of the second column 17, and the frustum 1701 abuts against the driven plate 22.

[0070] It should be noted that when the cable tray expands or contracts in the length direction, that is, when the first frame 2 transmits tensile or extensile force to the second frame 3 through the shaft 11, the second frame 3 will drive the second column 17 to slide in the strip groove 2201. The purpose of the second column 17 and the frustum 1701 is that when the cable tray shifts longitudinally, the movable seat 13 slides in the guide rail 12, and the frustum 1701 can drive the driven plate 22 to move relative to the second cross arm 8, thereby causing the sliding engagement to cause the sliding plate 19 to move on the second cross arm 8.

[0071] The arrangement of the second column 17, the frustum 1701 and the strip groove 2201 can avoid the mutual influence between the longitudinal offset compensation and the length direction expansion and contraction compensation of the cable tray, and both compensations are actively achieved through the column spring 7.

[0072] Please refer to it again. Figure 12 The sliding fitting includes a transmission plate 20 fixedly installed on the side of the sliding plate 19 and a follower arm 23 fixed to the end of the column 21 away from the driven plate 22. The follower arm 23 is fixedly provided with a protruding post 24 at the end away from the column 21. The transmission plate 20 is provided with an inclined through groove 2201 adapted to the protruding post 24. The inclined through groove 2201 is inclined, and the protruding post 24 extends into the inclined through groove 2001 and is slidably connected to the transmission plate 20. When the driven plate 22 moves away from the second cross arm 8, the protruding post 24 slides along the strip through groove 2001 and can cause the transmission plate 20 to drive the sliding plate 19 to slide towards the middle position of the second cross arm 8.

[0073] Specifically, when the movable seat 13 slides on the guide rail 12, causing the frustum 1701 to move the driven plate 22 away from the second cross arm 8, the column 21, the follower arm 23, and the protruding column 24 move together with the driven plate 22. The protruding column 24 slides with the driven plate 22 through the strip groove 2201, causing the driven plate 22 to move the sliding plate 19 to give way. That is, the sliding plate 19 slides on the second cross arm 8 toward the middle part of the second cross arm 8. Correspondingly, the first slider 9 slides on the cross bar 6, causing the columnar spring 7 to deform, thereby realizing active compensation for the longitudinal offset of the cable tray.

[0074] As another embodiment of the present invention, a compensation method for intelligent long-span cable trays by the active compensator is also proposed. When the cable tray extends or retracts in its own length direction, the first frame 2 transmits the extension force to the second frame 3 through the shaft 11, and the first slider 9 slides on the crossbar 6, causing the column spring 7 to deform.

[0075] When the cable tray shifts longitudinally, the first frame 2 and the second frame 3 rotate relative to each other through the shaft 11, causing the follower mechanism to drive the sliding plate 19 to slide the second slider 10 on the crossbar 6, and the column spring 7 deforms.

[0076] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0077] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
