[0038] The transverse support frame components distributed on the left and right sides of the connection plate and inclined to the longitudinal main frame, by changing their own inclination angles, can not only push their respective connection mechanisms to slide within the longitudinal main frame, but also change the distance between them and the transverse support frame components perpendicular to the longitudinal main frame. The transverse support frame components inclined to the longitudinal support frame, by changing the inclination angles, can adaptively adjust the geometric shape of the triangular truss structure, making the support points of the transverse support frame components on the longitudinal main frame more reasonably distributed, balancing the stress distribution of the overall structure of the longitudinal main frame, enabling the cable tray to achieve the best stress state under different load distributions, avoiding local overload of the cable tray, and thus enhancing the load-bearing performance of the cable tray;

Detailed implementation manners

[0054] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0055] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0056] As Figures 1 to 9 shown, as a load-bearing aluminum alloy cable tray provided in an embodiment of the present invention, it includes a longitudinal main frame 100 and a connection disk 200. The connection disk 200 is located between two longitudinal main frames 100, and further includes:

[0057] A transverse support frame assembly 300, the transverse support frame assembly 300 is distributed on the left and right sides of the connection disk 200. There are three transverse support frame assemblies 300 on the same side of the connection disk 200. One of the transverse support frame assemblies 300 is perpendicular to the longitudinal main frame 100, and the other two transverse support frame assemblies 300 are distributed on the front and rear sides of one of the transverse support frame assemblies 300 and are both inclined to the longitudinal main frame 100;

[0058] A control mechanism 400, the control mechanism 400 includes a main control component 410, a winding component 420 and a steel cable 430. The main control component 410 and the winding component 420 are both installed on the connection disk 200. One end of the main control component 410 is connected to one end of the winding component 420, and the steel cable 430 is wound around the other end of the winding component 420;

[0059] A connection mechanism 500, the connection mechanism 500 is slidably arranged in the longitudinal main frame 100 and is connected to one end of the transverse support frame assembly 300. One end of the steel cable 430 passes through the transverse support frame assembly 300 and is connected to the connection mechanism 500. The upper and lower ends of the connection mechanism 500 are intermittently frictionally connected to the longitudinal main frame 100;

[0060] The transverse support frame assemblies 300 distributed on the left and right sides of the connection disk 200 and perpendicular to the longitudinal main frame 100 can adjust and limit the distance between the two longitudinal main frames 100 to ensure that it always remains within a suitable range, providing a basic guarantee for the overall structural stability of the cable tray; the transverse support frame assembly 300 perpendicular to the longitudinal main frame 100 and the transverse support frame assembly 300 inclined to the longitudinal main frame 100 can cooperate with each other to form a triangular truss structure, significantly improving the lateral force resistance and torsional deformation resistance of the cable tray. At the same time, the triangular truss structure can also absorb the vibration received by the longitudinal main frame 100 during operation, reduce the material fatigue caused by long-term vibration, and extend the service life of the cable tray;

[0061] The transverse support frame assemblies 300 distributed on the left and right sides of the connection plate 200 and inclined to the longitudinal main frame 100 can, by changing their own inclination angles, not only push their respective connection mechanisms 500 to slide within the longitudinal main frame 100, but also change the distance between them and the transverse support frame assemblies 300 perpendicular to the longitudinal main frame 100. The transverse support frame assemblies 300 inclined to the longitudinal support frame can, by changing the inclination angles, adaptively adjust the geometric shape of the triangular truss structure, so that the support points of the transverse support frame assemblies 300 on the longitudinal main frame 100 can be more reasonably distributed, balance the stress distribution of the overall structure of the longitudinal main frame 100, enable the cable tray to reach the best stress state under different load distributions, avoid the phenomenon of local overload of the cable tray, and thus improve the load-bearing performance of the cable tray;

[0062] After the position and angle of the transverse support frame assembly 300 are adjusted, the main control assembly 410 drives the winding assembly 420, and the winding assembly 420 winds the steel cable 430. The wound steel cable 430 can drive a plurality of connection mechanisms 500 to work synchronously, so that the plurality of connection mechanisms 500 can apply a stable tightening force to the longitudinal main frame 100 at the same time, thereby completing the stable connection between the plurality of transverse support frame assemblies 300 and the longitudinal main frame 100, improving the installation efficiency of the transverse support frame assembly, reducing the installation time of the transverse support assembly, and ensuring the connection strength between the transverse support frame assembly 300 and the longitudinal main frame 100 under the normal working condition of the cable tray, effectively avoiding a series of problems caused by the offset or sliding of the transverse support frame assembly 300, ensuring that the cable tray can maintain efficient and stable performance during long-term operation, and extending its service life.

[0063] In a preferred embodiment, the longitudinal main frame 100 is an aluminum alloy columnar structure manufactured by die casting, and grooves for the connection mechanism 500 and the hanger to slide are distributed around it.

[0064] As Figures 1 to 7 shown, as a preferred embodiment of the present invention, the transverse support frame assembly 300 includes a set of parts one 310, a cross support frame one 320, a cross support frame two 330, and a set of parts two 340. One end of the set of parts one 310 is distributed on the left and right sides of the connection plate 200, the other end of the set of parts one 310 is fixedly connected to one end of the cross support frame one 320, the cross support frame two 330 is horizontally slidably mounted on the other end of the cross support frame one 320, one end of the cross support frame two 330 is fixed with the set of parts two 340, and the set of parts two 340 is connected to the connection mechanism 500 slidably arranged on the longitudinal main frame 100;

[0065] For the transverse support assembly 300 perpendicular to the longitudinal main frame 100, the first set 310 thereon can be fixedly connected to the connecting plate 200 by bolts, and the second set 340 thereon can also be fixedly connected to the connecting mechanism 500 by bolts, which can ensure the perpendicularity between it and the longitudinal main frame 100, thereby realizing the precise adjustment of the distance between the two longitudinal main frames 100 and ensuring the parallelism between the two longitudinal main frames 100;

[0066] For the transverse support assembly 300 inclined to the longitudinal main frame 100, the first set 310 thereon can be rotatably installed on the connecting plate 200 through a pin shaft, and the second set 340 thereon can also be rotatably connected to the connecting mechanism 500 through a pin shaft. In this way, during the process of adjusting the inclination of the first cross support 320 and the second cross support 330, it can be ensured that the connecting mechanism 500 can move synchronously with the second cross support 330;

[0067] During the process of adjusting the distance between the two longitudinal main frames 100 or the position of the support points, the second cross support 330 can freely slide horizontally on the first cross support 320, and through holes with consistent positions can be distributed on the first cross support 320 and the second cross support 330. In this way, after the second cross support 330 completes the sliding work, the through holes can be blocked by bolts or other shaft parts, thereby limiting the second cross support 330 so that it cannot freely slide on the first cross support 320. Thus, when the cable tray is working normally, the connection strength between the transverse support assembly 300 and the longitudinal main frame 100 can be ensured, effectively avoiding a series of problems caused by the offset or sliding of the transverse support assembly 300, ensuring that the cable tray can maintain efficient and stable performance during long-term operation, and extending its service life.

[0068] In a preferred embodiment, the first set 310, the first cross support 320, the second cross support 330, and the second set 340 are all preferably made of aluminum alloy material and are all manufactured by die-casting process.

[0069] As Figure 3 、 Figure 4 、 Figures 10 to 12 shown, as a preferred embodiment of the present invention, the main control component 410 includes a rotating shaft 411, a turning handle 412, a limit bolt 413, and a limit disc 414. The rotating shaft 411 is vertically and slidably installed on the connecting plate 200. One end of the rotating shaft 411 is fixed with a turning handle 412. The turning handle 412 can cooperate with the circumferentially distributed limit holes 415 on the limit disc 414 through the limit bolt 413. The limit disc 414 is concentric with the rotating shaft 411 and is fixed on the connecting plate 200. A connecting card slot 416 cooperating with the winding component 420 is provided on the side wall of the other end of the rotating shaft 411;

[0070] When the horizontal support frame assembly 300 is adjusted in position and angle, the position of the connecting mechanism 500 also changes and pulls the steel rope 430. Before this process, the vertical position of the rotating shaft 411 can be adjusted so that the connecting card slot 416 on the rotating shaft 411 is located above the winding assembly 420, avoiding movement interference of the rotating shaft 411 on the steel rope 430. After the position and angle of the horizontal support frame assembly 300 are adjusted, the rotating shaft 411 is pressed so that the connecting card slot 416 on it cooperates with the winding assembly 420 again. The handle 412 drives the rotating shaft 411 to rotate, and the rotating shaft 411 drives the winding assembly 420 to rotate through the connecting card slot 416. The winding assembly 420 can complete the winding of the steel rope 430 by rotating. The wound steel rope 430 can drive multiple connecting mechanisms 500 to work, enabling the multiple connecting mechanisms 500 to synchronously apply a stable tightening force to the longitudinal main frame 100, thereby completing the stable connection between the multiple horizontal support frame assemblies 300 and the longitudinal main frame 100, ensuring the connection strength between the multiple horizontal support frame assemblies 300 and the longitudinal main frame 100, effectively avoiding a series of problems caused by the offset or sliding of the horizontal support frame assembly 300, ensuring that the cable tray can maintain efficient and stable performance during long-term operation, extending its service life, and at the same time reducing the installation time of the cross support frame assembly and improving the assembly efficiency of the cable tray;

[0071] After the winding work of the steel rope 430 is completed, the handle 412 and the limit disc 414 are connected as a whole by the limit bolt 413, and the radial and axial directions of the handle 412 are limited, so as to ensure the installation stability of the rotating shaft 411 under the normal working condition of the cable tray, and further ensure the connection stability between the connecting mechanism 500 and the longitudinal main frame 100.

[0072] In a preferred embodiment, the limit disc 414 preferably adopts an annular block structure;

[0073] The limit bolt 413 can clamp the upper and lower end faces of the limit disc 414 and the handle 412, thereby completing the radial and axial limits of the handle 412 and the rotating shaft 411.

[0074] Such as Figure 3 、 Figure 4 、 Figures 10 to 12As shown, as a preferred embodiment of the present invention, the winding assembly 420 includes a sleeve 421, a chute 422, a connecting clip 423, a first spring 424, a main gear 425, a sub-gear 426 and a winding disc 427. One end of the sleeve 421 is rotatably installed on the connecting disc 200. The inner wall of the other end of the sleeve 421 is vertically slidably connected to the rotating shaft 411. Chutes 422 are symmetrically formed on the left and right sides of the other end of the sleeve 421. The connecting clip 423 is slidably installed in the chute 422 through the first spring 424. The connecting clip 423 cooperates with the connecting slot 416. The main gear 425 is fixed on the outer wall of one end of the sleeve 421. Sub-gears 426 with the same number as the cross-bracing frame assemblies are circumferentially distributed outside the main gear 425. A plurality of the sub-gears 426 are all meshed with the main gear 425, and a plurality of the sub-gears 426 are all rotatably installed on the connecting disc 200. A winding disc 427 is coaxially fixed on the sub-gear 426. One end of the steel rope 430 is wound around the winding disc 427;

[0075] The sleeve 421 is preferably a rotating body with a T-shaped cross-section. The sleeve 421 and the main gear 425 are both concentric with the rotating shaft 411;

[0076] The connecting clip 423 is preferably a connecting structure composed of a trapezoidal block and a T-shaped rod. The inclined end face of the trapezoidal block cooperates with the connecting slot 416, which helps the rotating shaft 411 to quickly release or restore the connection state with the connecting clip 423 by vertical movement;

[0077] When the connecting slot 416 on the rotating shaft 411 cooperates with the connecting clip 423, the rotating shaft 411 can drive the sleeve 421 to rotate synchronously through the cooperation of the connecting slot 416 and the connecting clip 423. The sleeve 421 drives the main gear 425 to rotate. The main gear 425 drives a plurality of sub-gears 426 to rotate synchronously. A plurality of sub-gears 426 drive their respective winding discs 427 to rotate synchronously, so that a plurality of winding discs 427 can wind their respective steel ropes 430. A plurality of the wound steel ropes 430 can drive their respective connection mechanisms 500 to work, so that a plurality of connection mechanisms 500 can simultaneously apply a stable tightening force to the longitudinal main frame 100, thereby completing the stable connection of a plurality of transverse bracing frame assemblies 300 and the longitudinal main frame 100, reducing the installation time of the cross-bracing frame assemblies, and improving the assembly efficiency of the cable tray.

[0078] In a preferred embodiment, the winding disk 427 is preferably a rotating body with an H-shaped cross-section, and a spiral elastic sheet (spring) can be arranged between one end of the winding disk 427 and the connecting disk 200, so that the spiral elastic sheet can reel in the relaxed steel rope 430 in time through its own elastic force, thereby improving the driving efficiency of the control mechanism 400.

[0079] like Figures 3 to 9 As shown, as a preferred embodiment of the present invention, the connecting mechanism 500 includes a convex slider 510, a connecting component 520 and a pulley assembly 540, the convex slider 510 is slidably arranged in the longitudinal main frame 100, and one side of the convex slider 510 is connected to the kit 2 340, a guide groove 1 511 is opened inside the convex slider 510, and the upper and lower ends of the guide groove 1 511 are opened with a guide groove 2 512 connected thereto, one end of the connecting component 520 is horizontally slidably installed in the guide groove 1 511 and is connected to the steel rope 430, the other end of the connecting component 520 is vertically slidably installed in the guide groove 2 512 and is frictionally connected to the longitudinal main frame 100, and a pulley assembly 540 for guiding the steel rope 430 is fixed to one side of the convex slider 510.

[0080] When the winding drum 427 is in the process of winding the steel rope 430, the multiple steel ropes 430 can synchronously pull the multiple connection components 520, so that one end of the multiple connection components 520 synchronously slides horizontally in the guide groove 1 511, and one end of the multiple connection components 520 synchronously drives the other end to slide vertically in the guide groove 2 512. The other ends of the multiple connection components 520 can apply a stable clamping force to the longitudinal main frame 100 by synchronous vertical sliding, thereby completing the stable connection of the multiple transverse support frame assemblies 300 with the longitudinal main frame 100, improving the installation efficiency of the transverse support frame assemblies, and reducing the installation time of the transverse support assemblies. When the wiring rack is working normally, the connection strength between the transverse support frame assembly 300 and the longitudinal main frame 100 can be ensured, effectively avoiding a series of problems caused by the displacement or sliding of the transverse support frame assembly 300, and ensuring that the wiring rack can maintain efficient and stable performance during long-term operation, thereby extending its service life.

[0081] In a preferred embodiment, the outer shape of the convex slider 510 matches the grooves distributed on the longitudinal main frame 100, which not only ensures that the convex slider 510 can slide smoothly in the longitudinal main frame 100, but also prevents the convex slider 510 from moving synchronously with the steel rope 430 when it is pulled, ensuring that the connecting assembly 520 can work faster and more stably when the steel rope 430 is pulled, so that the connecting assembly 520 can be pressed against the longitudinal main frame 100 faster and more effectively;

[0082] The pulley assembly 540 preferably adopts a pulley assembly 540 composed of two fixed pulleys, and the two fixed pulleys are distributed on both sides of the steel rope.

[0083] like Figures 3 to 9 As shown, as a preferred embodiment of the present invention, the connecting assembly 520 includes a main control slider 521, a connecting slider 522 and a second spring 523. The main control slider 521 is horizontally slidably installed in the guide groove 1 511 and is fixedly connected to the steel rope 430. The connecting sliders 522 are distributed at the upper and lower ends of the main control slider 521 and are slidably connected to the second guide groove 512. A second spring 523 is installed between the two connecting sliders 522. The end surfaces of the main control slider 521 and the connecting slider 522 that conflict with each other are both inclined end surfaces.

[0084] Spring 2 523 drives the two connecting sliders 522 to tightly contact the main control slider 521 through its own elastic force, and multiple steel ropes 430 can simultaneously drive multiple main control sliders 521 to slide horizontally in guide groove 1 511. The main control slider 521 can drive the two connecting sliders 522 distributed at its upper and lower ends to slide in the opposite direction in guide groove 2 512 by horizontal sliding, thereby expanding the distance between the two, so that the two connecting sliders 522 move toward the direction close to the longitudinal main frame 100, and the connecting sliders 522 in the multiple connecting components 520 can apply a stable clamping force to the longitudinal main frame 100 at the same time by synchronous vertical sliding, thereby completing the stable connection of multiple horizontal support frame components 300 and the longitudinal main frame 100.

[0085] In a preferred embodiment, when a spiral elastic sheet is provided between the winding disk 427 and the connecting disk 200, the elastic force of the second spring 523 is greater than the elastic force of the spiral elastic sheet;

[0086] An anti-skid pad 530 is distributed on the end surface of the connecting slider 522 that contacts the longitudinal main frame 100. The anti-skid pad 530 can increase the friction performance between the connecting slider 522 and the longitudinal main frame 100, thereby improving the connection strength between the longitudinal main frame 100 and the transverse support frame assembly 300.

[0087] The working principle of the present invention is:

[0088] The transverse support frame assembly 300, which is distributed on the left and right sides of the connection plate 200 and perpendicular to the longitudinal main frame 100, can adjust and limit the distance between the two longitudinal main frames 100 to ensure that it always remains within a suitable range, providing a basic guarantee for the overall structural stability of the cable tray; the transverse support frame assembly 300 perpendicular to the longitudinal main frame 100 and the transverse support frame assembly 300 inclined to the longitudinal main frame 100 can cooperate with each other to form a triangular truss structure, significantly improving the lateral force resistance and torsional deformation resistance of the cable tray. At the same time, the triangular truss structure can also absorb the vibration received by the longitudinal main frame 100 during operation, reducing the material fatigue caused by long-term vibration;

[0089] The transverse support frame assembly 300, which is distributed on the left and right sides of the connection plate 200 and inclined to the longitudinal main frame 100, can not only push its respective connection mechanism 500 to slide within the longitudinal main frame 100 by changing its own inclination angle, but also change the distance between it and the transverse support frame assembly 300 perpendicular to the longitudinal main frame 100. The transverse support frame assembly 300 inclined to the longitudinal support can adaptively adjust the geometric shape of the triangular truss structure by changing the inclination angle, so that the support points of the transverse support frame assembly 300 on the longitudinal main frame 100 can be more reasonably distributed, balancing the stress distribution of the overall structure of the longitudinal main frame 100, so that the cable tray can achieve the best stress state under different load distributions;

[0090] After the position and angle of the transverse support frame assembly 300 are adjusted, the position of the connection mechanism 500 also changes and pulls the steel cable 430. Before this process, the vertical position of the rotating shaft 411 can be adjusted so that the connection card slot 416 on the rotating shaft 411 is located above the winding assembly 420 to avoid the rotating shaft 411 causing movement interference to the steel cable 430;

[0091] After the position and angle of the horizontal support frame assembly 300 are adjusted, press the rotating shaft 411 and make the connecting card slot 416 thereon cooperate with the winding assembly 420 again. The handlebar 412 drives the rotating shaft 411 to rotate. Through the cooperation of the connecting card slot 416 on the rotating shaft 411 and the connecting card 423, the sleeve 421 can be driven to rotate synchronously. The sleeve 421 drives the main gear 425 to rotate, the main gear 425 drives a plurality of sub-gears 426 to rotate synchronously, and the plurality of sub-gears 426 drive their respective winding discs 427 to rotate synchronously, so that the plurality of winding discs 427 can wind their respective steel ropes 430. The plurality of steel ropes 430 can simultaneously drive a plurality of main control sliders 521 to slide horizontally in the first guide groove 511. The main control slider 521 can drive the two connecting sliders 522 distributed at its upper and lower ends to slide in the second guide groove 512 in the opposite direction by means of horizontal sliding, thereby expanding the distance between the two, so that the two connecting sliders 522 move toward the longitudinal main frame 100. The connecting sliders 522 in the plurality of connecting assemblies 520 can apply a stable tightening force to the longitudinal main frame 100 by means of synchronous vertical sliding, thereby ensuring that the plurality of horizontal support frame assemblies 300 can synchronously complete the stable connection to the longitudinal main frame 100;

[0092] The above is the working principle of the load-bearing aluminum alloy cable tray.

[0093] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
