Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a stepped epoxy resin composite high-strength cable tray. Background Technology

[0002] As a key component in electrical wiring systems, cable trays play a crucial role in supporting, protecting, and managing cables, wires, and other wiring. They are widely used in various fields, including industry, commerce, and construction. Cable trays come in a wide variety of types. Structurally, they include trough-type, tray-type, ladder-type, and mesh-type cable trays, each with its own advantages in terms of application scenarios and functional characteristics. From a material perspective, they include stainless steel cable trays, aluminum alloy cable trays, steel cable trays, and epoxy resin composite cable trays. The differences in materials determine the performance of the cable tray in terms of strength, corrosion resistance, and weight.

[0003] Among these cable tray types, stepped epoxy resin composite high-strength cable trays are favored in specific scenarios due to their high strength and good corrosion resistance. However, this type of cable tray has a significant problem in use. Because they are usually custom-made, the dimensions cannot be changed once determined. But in actual installation, the environment of the installation location varies greatly, and factors such as spatial layout and surrounding facilities will impose different requirements on the installation dimensions of the cable tray. This means that custom-made fixed-size cable trays often fail to perfectly fit the site environment, easily resulting in dimensional deviations, and thus failing to meet the usage requirements of the installation environment, causing many inconveniences to the smooth progress of electrical wiring projects. Utility Model Content

[0004] The purpose of this invention is to provide a stepped epoxy resin composite high-strength cable tray, aiming to solve the problem that existing cable trays are usually custom-made, and their dimensions cannot be changed once determined. However, in actual installation, the environment of the installation location varies greatly, and factors such as spatial layout and surrounding facilities will impose different requirements on the installation dimensions of the cable tray. This leads to custom-made fixed-size cable trays often failing to perfectly fit the site environment, easily resulting in dimensional deviations, and thus failing to meet the usage requirements of the installation environment, causing many inconveniences to the smooth progress of electrical wiring projects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stepped epoxy resin composite high-strength cable tray, comprising two symmetrical side beams, with crossbeams bolted to the inner walls of the two side beams, grooves formed on the surface of the crossbeams, extension plates slidably connected inside the grooves, sliders connected to the front and rear ends of the extension plates, sliding grooves formed on the inner walls of the grooves, and fixing pins threaded through the surface of the crossbeams, with rectangular blocks installed inside the side beams, and first threaded rods installed on the side walls of the rectangular blocks, with adjusting sleeves threaded onto the surface of the first threaded rods.

[0006] As a preferred embodiment of the stepped epoxy resin composite high-strength cable tray of this utility model, the slider is adapted to the slide groove, the extension plate is integrally connected to the slider and the cross section is "convex", and the groove has a "convex" cross section through the slide groove.

[0007] As a preferred embodiment of the stepped epoxy resin composite high-strength cable tray of this utility model, the extension plate can be detachably and fixedly connected to the crossbeam by means of fixing pins.

[0008] As a preferred embodiment of the stepped epoxy resin composite high-strength cable tray of this utility model, there are two first threaded rods, and the threads on the surfaces of the two first threaded rods are opposite.

[0009] In a preferred embodiment of the stepped epoxy resin composite high-strength cable tray of this utility model, the two first threaded rods are threadedly connected to the adjusting sleeve.

[0010] As a preferred embodiment of the stepped epoxy resin composite high-strength cable tray of this utility model, a push plate is embedded in the inner wall of the side beam, a second threaded rod is threadedly connected to the side wall of the side beam, and a guide rod is through the side wall of the side beam.

[0011] In a preferred embodiment of the stepped epoxy resin composite high-strength cable tray of this utility model, the second threaded rod is rotatably connected to the end face of the push plate, and the guide rod is connected to the end face of the push plate. The push plate can move threadedly with the side beam through the second threaded rod and the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The cable tray size can be flexibly adjusted through the cooperation of the first threaded rod, adjusting sleeve, extension plate, slide groove, recess, slider, fixing pin, and rectangular block. Specifically, when the cable tray size needs to be adjusted, the fixing pin is first released from its squeezing and fixing effect on the extension plate. At this time, the crossbeam, with the help of the adjustable length of the extension plate, can move the two side beams closer together under the synergistic action of the first threaded rod and adjusting sleeve. The beneficial effects of this design are significant. In actual installation scenarios, the site environment is complex and diverse, and the requirements for cable tray size are also different. Through the above adjustment method, the cable tray size can be flexibly adjusted according to the actual site conditions, ensuring that the cable tray is perfectly adapted to the installation environment. This effectively avoids installation difficulties caused by the mismatch between the cable tray size and the environment, greatly improves the convenience and adaptability of cable tray installation, and ensures the smooth progress of electrical wiring projects.

[0014] A highly efficient cable position adjustment mechanism is formed through the interaction of a push plate, a second threaded rod, and a guide rod. The operator simply rotates the second threaded rod, and guided by the guide rod, the push plate smoothly moves out of the side beam. As the push plate moves, it pushes the cable just placed in the cable tray away from the inner wall of the side beam. The push plate then re-embeds into the inner wall of the side beam. The beneficial effect of this design is crucial. In actual use, if cables are in close contact with the side wall of the side beam for extended periods, it will severely affect the cable's heat dissipation, potentially leading to overheating, accelerated cable aging, and even safety hazards. Adjusting the cable position through this structure effectively increases the space between the cable and the side wall of the side beam, ensuring smooth airflow, significantly improving the cable's heat dissipation performance, extending its service life, and ensuring the safe and stable operation of the electrical system.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides the following technical solutions: A stepped epoxy resin composite high-strength bridge, including two symmetric side beams 1, the inner walls of the two side beams 1 are installed with cross beams 2 through bolts, the surface of the cross beam 2 is provided with a groove 4, an extension plate 3 is slidably connected inside the groove 4, the front and rear ends of the extension plate 3 are connected with sliding blocks 6, sliding grooves 5 are provided on the inner wall of the groove 4, a fixing pin 7 is threadedly penetrated through the surface of the cross beam 2, a rectangular block 8 is installed inside the side beam 1, a first threaded rod 9 is installed on the side wall of the rectangular block 8, and an adjusting sleeve 10 is threadedly sleeved on the surface of the first threaded rod 9.

[0023] During specific use, this stepped epoxy resin composite high-strength bridge is mainly composed of a side beam 1 and a cross beam 2. Both the side beam 1 and the cross beam 2 are carefully made of epoxy resin composite materials, which endow the bridge with a series of excellent properties such as high strength and corrosion resistance, enabling it to adapt to complex and changeable use environments. In the structural design, the cross beams 2 are assembled inside the side beams 1 at equal intervals, and such a layout makes the overall bridge present a unique stepped form.

[0024] Preferably: The sliding block 6 is adapted to the sliding groove 5, the extension plate 3 is integrally connected with the sliding block 6 and has a "convex" cross-section, and the cross-section of the groove 4 through the sliding groove 5 is "convex". The extension plate 3 can be detachably and fixedly connected to the cross beam 2 through the fixing pin 7. There are two first threaded rods 9, and the threads on the surfaces of the two first threaded rods 9 are opposite. The two first threaded rods 9 are threadedly connected to the adjusting sleeve 10.

[0025] During specific use, due to the matching of the dimensions of the sliding block 6 and the sliding groove 5, the extension plate 3 can smoothly slide with the cross beam 2. This cooperation method provides excellent stability for the bridge structure, effectively avoiding the shaking problem caused by a large gap, and ensuring the stability and reliability of the bridge during use.

[0026] It is worth mentioning that the extension plate 3 is designed in a "convex" shape, and the matching slider 6 is also in a "convex" shape. The cross beam 2 is provided with a matching "convex" shaped groove 4 and a chute 5. When the extension plate 3, the slider 6, the groove 4 and the chute 5 are connected, this unique shape design can ensure that the extension plate 3 is firmly fixed on the cross beam 2, preventing it from detaching, and further enhancing the overall stability of the bridge.

[0027] In addition, a fixing pin 7 is designed for the bridge. The fixing pin 7 can thread through the cross beam 2 to squeeze and fix the extension plate 3, thus effectively preventing the extension plate 3 from unnecessary movement during the use of the bridge, ensuring that the cable can be stably placed in the bridge and will not be affected by the shaking of the extension plate 3.

[0028] Finally, the bridge also adopts the design of two first threaded rods 9 with opposite thread directions. When the operator rotates the adjusting sleeve 10, due to the characteristics of the thread, these two first threaded rods 9 can achieve synchronous movement of approaching or separating from each other. This design enables the operator to conveniently adjust the positions of the two side beams 1 to meet different installation requirements, greatly improving the flexibility and practicality of the bridge.

[0029] Preferably: A push plate 11 is embedded in the inner wall of the side beam 1, a second threaded rod 12 is threadedly connected to the side wall of the side beam 1, and a guide rod 13 is connected through the side wall of the side beam 1. The second threaded rod 12 is rotatably connected to the end face of the push plate 11, the guide rod 13 is connected to the end face of the push plate 11, and the push plate 11 can form a threaded movement with the side beam 1 through the second threaded rod 12 and the guide rod 13.

[0030] In specific use, in this bridge structure, the second threaded rod 12 is connected to the side beam 1 in a threaded through manner. Based on this design, the operator only needs to rotate the second threaded rod 12, and it can achieve a linear movement of advancing or retreating relative to the side beam 1 by means of the thread.

[0031] The end of the second threaded rod 12 is rotatably connected to the push plate 11. When the second threaded rod 12 moves, the push plate 11 will have a moving tendency. However, without restrictive measures, the push plate 11 may rotate along with the second threaded rod 12 and cannot achieve the expected linear pushing effect.

[0032] To solve this problem, a guide rod 13 is provided through the side wall of the side beam 1, and one end of the guide rod 13 is fixedly connected to the end face of the push plate 11. The presence of the guide rod 13 plays a key guiding and limiting role. It can effectively prevent the push plate 11 from rotating along with the second threaded rod 12, enabling the push plate 11 to only perform a linear movement of advancing or retreating along with the second threaded rod 12.

[0033] Furthermore, the bottom end of the push plate 11 fits tightly against the top end of the crossbeam 2. This design ensures that the push plate 11 can stably act on the cables above the crossbeam 2 during movement, avoiding the inability to effectively push the cables at the top of the crossbeam 2 due to gaps between the push plate 11 and the top end of the crossbeam 2, thus ensuring the normal functioning of the cable tray's cable position adjustment function.

[0034] Working principle: First, the operator rotates the adjusting sleeve 10. Since the adjusting sleeve 10 is connected to two first threaded rods 9 with opposite thread directions, the adjusting sleeve 10 will drive the two first threaded rods 9 to move closer or further apart under the action of the threads. This movement of the first threaded rods 9 is further transmitted to the side beam 1, thereby realizing the adjustment of the position of the side beam 1.

[0035] Next, the cable tray is assembled. The operator inserts the extension plate 3 and the slider 6 into the groove 4 and slide 5 of the crossbeam 2, ensuring they can slide smoothly. Then, bolts are used to fix the crossbeam 2 to the inner wall of the side beam 1, thus completing the main assembly of the cable tray.

[0036] Next, the extension plate 3 is secured by pressing the fixing pin 7 through the crossbeam 2, ensuring the cable tray remains stable in its initial state. After assembly, the cable tray can be installed in the designated location.

[0037] After the cable is placed in the cable tray, the operator only needs to rotate the second threaded rod 12. Since the second threaded rod 12 is connected to the side beam 1 by a threaded connection, under the action of the thread, the second threaded rod 12 will move forward or backward in a straight line relative to the side beam 1.

[0038] The end of the second threaded rod 12 is rotatably connected to the push plate 11, while the push plate 11 is connected to the guide rod 13, which passes through the side wall of the side beam 1. When the second threaded rod 12 moves, it will drive the push plate 11 to move together, while the guide rod 13 plays a guiding and limiting role, preventing the push plate 11 from rotating with the second threaded rod 12, and ensuring that the push plate 11 can only move in a straight line.

[0039] The movement of the push plate 11 can push the cable that has just been placed in the cable tray away from the inner wall of the side beam 1. Afterwards, the push plate 11 re-embeds into the inner wall of the side beam 1 to maintain the stability of the cable tray structure.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
