Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and more specifically, to a cable tray with a partition arrangement function. Background Art

[0002] At present, most cable trays use a double-plate body constraint structure to achieve cable separation, that is, the cables are limited by two parallel or perpendicular plates. However, such a structure has natural design defects: the constraint between the plate body and the cable is achieved only through single-point or line contact. When the cable is subjected to lateral tension, vibration, or changes in laying density, the plate body is prone to displacement or deformation, resulting in the cable deviating from the original arrangement area, causing problems such as cable crossing and entanglement, extrusion and wear. For example, in the high-vibration environment of industrial workshops, the fixing screws of the double-plate body structure are prone to loosening, and after the plate body tilts, it loses the effective constraint on the cable; in scenarios where cables are densely laid, such as data centers, the self-weight and thermal expansion and contraction effects of the cables will cause uneven stress on the plate body, leading to local constraint failure and even short-circuit risks. In view of this, we propose a cable tray with a partition arrangement function. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a cable tray with a partition arrangement function to solve the technical problem of poor stability when separating and arranging cables currently.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A cable tray with a partition arrangement function, including a tray main body, on which multiple groups of fixed cable clamps and movable cable clamps are arranged. The multiple groups of fixed cable clamps and movable cable clamps are distributed in multiple columns, and cables are fixed between the inner circumferences of the multiple columns of fixed cable clamps and movable cable clamps. Constraint structures are provided on both the fixed cable clamps and the movable cable clamps, and an adaptive fixing structure is further provided above the fixed cable clamps and the movable cable clamps;

[0005] The adaptive fixing structure includes an adaptive insertion plate, which is a wavy structure and is made of a material with thermal expansion and contraction properties. A positioning plate is fixed between the tops of multiple adaptive insertion plates, and the positioning plate is fixed to the fixed cable clamp by bolts.

[0006] Preferably, the fixed cable clamp is fixedly connected to the tray main body, the movable cable clamp is in a limit sliding connection with the tray main body, and a placement notch is provided between the tops of the fixed cable clamp and the movable cable clamp.

[0007] Preferably, the constraint structure includes a rotating rod which is rotatably connected to a fixed cable clamp or a movable cable clamp. An outer sleeve is fixedly sleeved on the outer periphery of the rotating rod, and a rubber wheel is fixedly arranged on the outer periphery of the outer sleeve. The rubber wheel is made of elastic rubber material, and a part of the outer periphery of the rubber wheel is in contact with the outer periphery of the cable.

[0008] Preferably, the top end of the rotating rod penetrates through the fixed cable clamp or the movable cable clamp and is connected with a connecting sleeve. An extension rod is fixedly arranged on the outer periphery of the connecting sleeve. One end of the extension rod is fixedly provided with a soft colloid which is made of a soft and high-friction material.

[0009] Preferably, a side clamping wheel is connected to the bottom end of the soft colloid. The outer peripheries of the two side clamping wheels are in contact with and constraint the cable. A connecting link is connected between one side of the outer periphery of the side clamping wheel and the fixed cable clamp or the movable cable clamp.

[0010] Preferably, the adaptive insertion plate is provided with a first wave crest and a second wave crest.

[0011] Preferably, the adaptive fixing structure further includes a through-pressing opening for the adaptive insertion plate to pass through. The through-pressing opening is obliquely opened outward at the top of the movable cable clamp.

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

[0013] 1. In the utility model, multiple groups of fixed cable clamps and movable cable clamps on the bridge body are distributed in multiple columns, which play a role in constraining and separating the cables in an arranged manner and can perform preliminary clamping. Through the cooperation of the slider and the chute, the movable cable clamp can be limited to slide. When moving within the maximum range, the notch is larger than the diameter of the cable, which is convenient for the cable to be placed or inserted. The positioning plate is bolted to the fixed cable clamp and inserted into the movable cable clamp on the other side, so that the two form a separated arranged track, effectively avoiding the cross-winding of the cables and ensuring the orderly laying of the cables. The constraint structure is symmetrically distributed on both sides. The side clamping wheel is in contact with and constraints the outer periphery of the cable. The rubber wheel, the rotating rod, the connecting sleeve, the extension rod and the soft colloid work together. When the cable is displaced due to vibration or other conditions, the rubber wheel drives the relevant components to rotate, so that the soft colloid clamps towards the outer periphery of the cable, avoiding excessive sliding of the cable. Moreover, the elasticity of the soft colloid can be reset, which is convenient for multiple uses, enhancing the constraint stability of the cable and solving the problem of poor stability when separating and arranging the cables.

[0014] 2. The adaptive fixing structure of the present utility model also adopts a wavy design and a material with thermal expansion and contraction for the adaptive insertion plate. Its coefficient of thermal expansion is the same as that of the cable outer sheath. In a cold environment, the adaptive insertion plate shrinks due to cold, squeezing the moving cable clamp to move towards the fixed cable clamp, clamping the cold-shrunk cable more tightly; in a hot environment, the adaptive insertion plate expands and extends freely, which can adapt to different temperature environments, solving the problems of the clamping force reduction and loosening of the cable caused by thermal expansion and contraction, ensuring the stability of cable laying under different climatic conditions, and further solving the problem of poor stability when separating and arranging cables.

[0023] As Figures 1 to 5As shown in the figure, the utility model relates to a cable tray with a partition arrangement function, which includes a tray main body 1. A plurality of fixed cable clamps 2 and movable cable clamps 3 are arranged on the tray main body 1. The plurality of fixed cable clamps 2 and movable cable clamps 3 are distributed in multiple columns. Cables are fixed between the inner circumferences of the multiple columns of fixed cable clamps 2 and movable cable clamps 3. The fixed cable clamps 2 are fixedly connected to the tray main body 1, and the movable cable clamps 3 are in limit sliding connection with the tray main body 1, which is achieved by the cooperation of a slider and a chute. The fixed cable clamps 2 and the movable cable clamps 3 play a role in restraining and separating the arrangement of the cables and initially clamping them. There is a placement notch between the tops of the fixed cable clamps 2 and the movable cable clamps 3. When the movable cable clamp 3 moves to the maximum range, its notch is larger than the diameter of the cable to facilitate the placement or insertion of the cable. A positioning plate 6 is arranged above the fixed cable clamps 2 and the movable cable clamps 3. The positioning plate 6 is fixed to the fixed cable clamp 2 by bolts. On the other side of the positioning plate 6, there is a plate body inserted into the movable cable clamp 3, thereby realizing the constraint of the position, enabling the fixed cable clamps 2 and the movable cable clamps 3 to form a partition arrangement track and simultaneously initially constraining and positioning the cables. Constraint structures 4 are arranged on both the fixed cable clamps 2 and the movable cable clamps 3.

[0024] The constraint structure 4 includes side clamping wheels 407. A connecting rod 408 is connected between one side of the outer circumference of the side clamping wheel 407 and the fixed cable clamp 2 or the movable cable clamp 3. The cables are in contact with and constrained and clamped between the outer circumferences of two corresponding side clamping wheels 407. The constraint structure 4 further includes a rotating rod 401. The rotating rod 401 is rotatably connected to the fixed cable clamp 2 or the movable cable clamp 3. A fixed outer sleeve 402 is provided on the outer circumference of the rotating rod 401. A rubber wheel 403 is fixed to the outer circumference of the outer sleeve 402. The rubber wheel 403 is made of elastic rubber material. Part of the outer circumference of the rubber wheel 403 is in contact with the outer circumference of the cable. The top end of the rotating rod 401 penetrates through the fixed cable clamp 2 or the movable cable clamp 3 and is connected with a connecting sleeve 404. An extension rod 405 is fixed to the outer circumference of the connecting sleeve 404. One end of the extension rod 405 is fixed with a soft colloid 406. The soft colloid 406 is made of a soft material with high friction, such as natural rubber. The bottom end of the soft colloid 406 is fixed to the side clamping wheel 407. The side clamping wheel 407 is designed with a conical arc surface with an increasing diameter, so that the distance between its outer circumferential surface and the cable is reduced and it is easier to fit with the outer circumference of the cable.

[0025] Working principle: First, fix the cable chuck 2 and the movable cable chuck 3 to initially arrange and fix the cable. Then, use two side clamping wheels 407 to contact and restrict the outer circumference of the cable, further playing a role in further restriction. And when the cable vibrates or undergoes displacement, since the rubber wheel 403 is made of a material with high friction, it drives the fixed outer sleeve 402 to rotate, causing the rotating rod 401 to rotate, enabling the connecting sleeve 404 to rotate, further driving the elastic soft colloid 406 to clamp towards the outer circumference of the cable, avoiding excessive sliding of the cable. Moreover, the elasticity of the soft colloid 406 allows it to reset, facilitating the next use.

[0026] It should be noted that the restraint structure 4 is distributed symmetrically on both sides, enabling it to function when the cable slides in any direction on both sides.

[0027] Since the cable shrinks in a cold environment, the separated clamping part is prone to loosening, resulting in a decrease in the clamping force and easy movement of the cable. To address this point, the plate body on the other side of the positioning plate 6 that inserts into the movable cable chuck 3 is improved to an adaptive fixing structure 5.

[0028] The adaptive fixing structure 5 includes an adaptive insertion plate 501. The adaptive insertion plate 501 has a wavy structure and is made of a material with thermal expansion and contraction properties. Its material is preferably fiberglass-reinforced crosslinked polyethylene, which is an ideal material with both the characteristics of "the same coefficient of thermal expansion as the cable outer sheath" and "high hardness", especially suitable for cable system scenarios that require mechanical support and are sensitive to thermal deformation. Its performance is superior to that of traditional metal components without stress differences and ordinary plastics with high hardness, and it is one of the preferred solutions for rigid accessories in cable engineering.

[0029] The adaptive fixing structure 5 also includes a through-pressing port 502 for the adaptive insertion plate 501 to pass through. The through-pressing port 502 is inclined outwardly and opened at the top of the movable cable chuck 3. The adaptive insertion plate 501 is provided with a first wave crest 5011 and a second wave crest 5022.

[0030] Working principle: Due to the wavy shape and the design of the material with thermal expansion and contraction properties of the adaptive insertion plate 501, and the material being close to the same coefficient as the cable, the maximum degree of corresponding matching can be achieved.

[0031] When in a cold situation, the adaptive insertion plate 501 undergoes cold shrinkage. Since one end is fixed to the bottom of the positioning plate 6, it will contract towards the direction of the positioning plate 6, causing the wavy shape to contract. During the contraction process, the distance between the first wave crest 5011 and the second wave crest 5022 increases, thereby squeezing the movable cable chuck 3 to move towards the fixed cable chuck 2 to closely clamp the cold-shrunk cable.

[0032] When in a hot situation, the adaptive insertion plate 501 freely expands and extends away from the positioning plate 6, thus adapting to the hot situation.

[0033] The embodiments disclosed in the present utility model are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
