Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, and particularly relates to a heat-resistant and corrosion-resistant cable tray. Background Art

[0002] A cable tray is a bracket for supporting and laying cables, which can be divided into various structures, such as trough type, tray type, ladder type, grid type, etc. These structures are composed of brackets, cantilever arms and installation accessories, etc. They can be erected independently or attached to various building and pipe gallery brackets. Inside a building, the cable tray should reflect the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. It is widely used in many fields such as construction, transportation, energy, electric power, petrochemical industry, light industry, etc., and is an important carrier for cable laying.

[0003] For example, cable trays used in some special environments, such as chemical plants, hazardous waste treatment plants, outdoor areas, etc., have relatively high requirements for high temperature resistance or corrosion resistance. However, most of the existing heat-resistant and corrosion-resistant cable trays adopt simple crossbeam and bracket structures, lacking an effective cable fixing and separation mechanism. Therefore, during actual use, cables often have problems such as mutual extrusion and entanglement, which not only increases the maintenance difficulty, but also the mutual extrusion and interference between cables will affect the performance of the cables themselves.

[0004] In view of this, this application is specifically proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heat-resistant and corrosion-resistant cable tray to solve the problems raised in the above background art.

[0006] To solve the above technical problems, a heat-resistant and corrosion-resistant cable tray provided by the utility model includes two side plates with the same structure and arranged in parallel. At the bottom ends of the side walls of the two side plates close to each other, a plurality of crossbeams are fixedly connected. Corrosion-resistant coatings are laid on the outer surfaces of the side plates and the crossbeams. At the top of the crossbeam at one end of the side plate, a plurality of groups of limiting mechanisms are slidably connected. Each group of limiting mechanisms includes a limiting plate one and a limiting plate two which are respectively slidably connected to the top of the crossbeam. At the centers of the side walls of the limiting plate one and the limiting plate two close to each other, the same pin shaft is rotatably connected. The limiting plate one and the limiting plate two have the same structure and are rotationally symmetric about the axis of the pin shaft.

[0007] Furthermore, on both sides of the top of the crossbeam along its length direction, a plurality of equally spaced chute ones are respectively opened. The chute ones on both sides of the top of the crossbeam are centrosymmetric about the center of the top of the crossbeam. There is a spacing between adjacent two chute ones, and the chute ones on the same side of the top of the crossbeam are located on the same horizontal straight line.

[0008] Further, the longitudinal cross-sections of the first limiting plate and the second limiting plate are both "S"-shaped. The first limiting plate and the second limiting plate are not in the same vertical plane. The first limiting plate is rotatably connected to the adjacent second limiting plate that is not in the same set of limiting mechanisms. Vertically penetrating channels are provided at the centers of the sides of the first limiting plate and the second limiting plate where the bottoms are far away from each other. A fixing seat is rotatably connected in the channels. A slider is fixedly connected to the bottom of the fixing seat, and the slider is slidably connected in the first chute.

[0009] Further, the top of the slider is higher than the top of the crossbeam. Both ends of the pin shaft at the rotational connection of the first limiting plate and the second limiting plate in the middle are rotatably connected to a support frame. One end of the support frame far away from the pin shaft is fixedly connected to a first spring telescopic rod, and the end of the first spring telescopic rod far away from the support frame is fixedly connected to the top of the crossbeam.

[0010] Further, the tops of several first limiting plates and second limiting plates are all abutted against the same pressing plate. Horizontal sliding columns are fixedly connected to both ends of the pressing plate. The pressing plate is arranged parallel to the crossbeam. Storage grooves are provided on the side walls of the two side plates close to each other corresponding to the ends of the pressing plate.

[0011] Further, a limiting block is fixedly connected to the center of the inner side wall of the storage groove far away from the pressing plate. There is a gap between the outer side wall of the limiting block and the inner side wall of the storage groove. A first groove is provided at equal intervals in the vertical direction on one side wall of the limiting block. The extending direction of the first groove is away from the inner wall of the bottom of the storage groove and is inclined towards the middle of the side plate.

[0012] Further, a second groove is provided at the top of the side wall of the storage groove far away from the first groove. The second groove communicates with the storage groove. A wedge-shaped block is embedded in the second groove, and the inclined surface of the wedge-shaped block faces the pressing plate.

[0013] Further, the end of the sliding column far away from the pressing plate is located in the storage groove and is adapted to the first groove. The end of the sliding column far away from the pressing plate is adapted to the second groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By providing a limiting mechanism including a first limiting plate and a second limiting plate, channels for the cable to pass through are formed between the first limiting plates and the second limiting plates in adjacent two limiting mechanisms, so that the cables can be effectively separated horizontally on the cable tray, avoiding mutual interference and signal loss. At the same time, under the action of the pressing plate, not only can the cables be separated vertically, but also the first limiting plate and the second limiting plate can be driven to rotate to change the size of the channel, adapting to different types of cables and further clamping the cables, reducing the shaking of the cables caused by external forces.

[0024] 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.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: including two side plates 10 with the same structure and arranged in parallel with each other. At the bottom ends of the side walls of the two side plates 10 close to each other, a plurality of cross beams 11 are fixedly connected. Corrosion-resistant coatings are laid on the outer surfaces of the side plates 10 and the cross beams 11. On the top of the cross beam 11 at one end of the side plate 10, a plurality of groups of limiting mechanisms are slidably connected. Each group of limiting mechanisms includes a first limiting plate 20 and a second limiting plate 21 that are respectively slidably connected to the top of the cross beam 11. At the centers of the side walls of the first limiting plate 20 and the second limiting plate 21 close to each other, the same pin shaft is rotatably connected. The first limiting plate 20 and the second limiting plate 21 have the same structure and are rotationally symmetric about the axis of the pin shaft.

[0026] It should be noted that: a plurality of uniformly distributed heat dissipation holes are opened on the side walls of the two side plates 10 away from each other, and a relatively large distance exists between adjacent cross beams 11 to assist in the heat dissipation of the cable;

[0027] The side plates 10 and the cross beam 11 are made of the same material, which is a material that can withstand high temperatures, such as one or several of stainless steel, aluminum alloy, etc. Adjacent two side plates 10 are connected by connecting pieces, and details are not elaborated here.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: on both sides of the top of the cross beam 11 along its length direction, a plurality of equally spaced chute ones are respectively opened. The chute ones on both sides of the top of the cross beam 11 are symmetrically arranged about the center of the top of the cross beam 11. There is a spacing between adjacent two chute ones, and the chute ones on the same side of the top of the cross beam 11 are located on the same horizontal straight line.

[0029] It should be noted that: the chute one guides and limits the movement trajectories of the limiting plate one 20 and the limiting plate two 21, and at the same time reduces the friction generated between the limiting plate one 20 and the limiting plate two 21 and the cross beam 11 during movement.

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution: the longitudinal sections of the limiting plate one 20 and the limiting plate two 21 are both "S" - shaped. The limiting plate one 20 and the limiting plate two 21 are not in the same vertical plane. The limiting plate one 20 is rotatably connected to the adjacent limiting plate two 21 that is not in the same set of limiting mechanisms. At the centers of the sides where the bottoms of the limiting plate one 20 and the limiting plate two 21 are far away from each other, there are both vertically penetrating channels one. A fixing seat 23 is rotatably connected in the channel one. The bottom of the fixing seat 23 is fixedly connected with a slider 24, and the slider 24 is slidably connected in the chute one.

[0031] It should be noted that: the limiting plate one 20 and the limiting plate two 21 in the same set of limiting mechanisms are arranged in an interlaced manner. The end parts of the limiting plate one 20 and the limiting plate two 21 in adjacent two sets of limiting mechanisms that are close to each other are rotatably connected by a pin shaft. That is, the limiting plate one 20 and the limiting plate two 21 in the same set of limiting mechanisms form an "X" - shaped cross - rotational connection, and the limiting plate one 20 and the limiting plate two 21 in adjacent two sets of limiting mechanisms form a "V" - shaped rotational connection, thereby realizing linkage;

[0032] The "S" - shaped structure of the limiting plate one 20 and the limiting plate two 21. The area formed between adjacent limiting plate one 20 and limiting plate two 21 not only allows the cable to pass through, but also can well separate the cables, reducing the winding and stacking of the cables. In addition, cables can also be placed on the top of the pressing plate 32 to achieve the upper and lower stratification of the cables. Moreover, the pressing plate 32 can be determined by the groove one of the limiting block 31, thereby affecting the rotation angle and spacing of the limiting plate one 20 and the limiting plate two 21, further increasing the spacing of the cables and clamping the cables, reducing the negative impacts brought by the increase of cables, such as stacking, easy winding, and inconvenient maintenance.

[0033] Please refer toFigures 1-4 , the present utility model provides a technical solution: the top of the slider 24 is higher than the top of the cross beam 11. Both ends of the pin shaft at the rotation connection of the first limiting plate 20 and the second limiting plate 21 located in the middle are rotatably connected to a support frame 22. One end of the support frame 22 away from the pin shaft is fixedly connected to a first spring telescopic rod, and the end of the first spring telescopic rod away from the support frame 22 is fixedly connected to the top of the cross beam 11.

[0034] It should be noted that: the top of the slider 24 is higher than that of the cross beam 11 to prevent the first limiting plate 20 and the second limiting plate 21 from being blocked by the cross beam 11 when rotating relative to the slider 24;

[0035] The support frame 22 is located at the position of the rotation connection of the first limiting plate 20 and the second limiting plate 21 in the middle. The support frame 22 is used to limit the first limiting plate 20 and the second limiting plate 21 from extending to both sides with the middle of the top of the cross beam 11 as the origin during the extension. The first spring telescopic rod at the bottom end of the support frame 22 is used to adapt to the change in the position of the connection caused by the mutual rotation of the first limiting plate 20 and the second limiting plate 21, and is also used to adapt to the downward pressure of the pressing plate 32.

[0036] Please refer to Figures 1-4 , the present utility model provides a technical solution: the tops of a plurality of the first limiting plates 20 and the second limiting plates 21 are all abutted against the same pressing plate 32. Both ends of the pressing plate 32 are fixedly connected with horizontal sliding columns 33. The pressing plate 32 is arranged parallel to the cross beam 11. Corresponding to the ends of the pressing plate 32, storage grooves 30 are opened on the inner side walls of the two side plates 10 close to each other.

[0037] It should be noted that: the pressing plate 32 is also used to separate the cables up and down, that is, cables can also be placed on the top of the pressing plate 32. The sliding column 33 itself is an elastic telescopic structure, which can be elastically telescoped in its axial direction and can bear a large force in the radial direction. The pressing plate 32 slides between the storage groove 30 and the limiting block 31 through the sliding column 33 to synchronously adjust the limiting mechanism.

[0038] Please refer to Figures 1-4 , the present utility model provides a technical solution: a limiting block 31 is fixedly connected to the center of the inner side wall of the storage groove 30 far away from the pressing plate 32. There is a gap between the outer side wall of the limiting block 31 and the inner side wall of the storage groove 30. A first set of grooves are opened at equal intervals in the vertical direction on one side wall of the limiting block 31. The extending direction of the first set of grooves is away from the inner wall of the bottom of the storage groove 30 and is inclined towards the middle of the side plate 10.

[0039] It should be noted that: there is a gap between the limiting block 31 and the storage groove 30. The first set of grooves are arranged obliquely upward and extend into the limiting block 31. Further, a vertical stop block is provided at the opening of the first set of grooves to form a barb;

[0040] Similarly, for the stability of the pressing plate 32 during movement, two or more storage slots 30 may be provided at the end of the pressing plate 32 .

[0041] See also Figures 1-4 The utility model provides a technical solution: a groove 2 is provided at the top of a side wall of the storage groove 30 away from the groove 1, the groove 2 and the storage groove 30 are interconnected, a wedge block is embedded in the groove 2, and the inclined surface of the wedge block is arranged toward the pressure plate 32.

[0042] It should be noted that the sliding column 33 at the end of the pressure plate 32 slides between the storage groove 30 and the limit block 31. When the pressure plate 32 needs to be taken out, the sliding column 33 is moved to the second groove. The sliding column 33 contracts under the guidance of the wedge block in the second groove and the pressure plate 32 is taken out.

[0043] See also Figures 1-4 The present invention provides a technical solution: one end of the sliding column 33 away from the pressure plate 32 is located in the storage groove 30 and is adapted to the first groove, and the other end of the sliding column 33 away from the pressure plate 32 is adapted to the second groove.

[0044] It should be noted that: when the pressure plate 32 is pressed down, the spring telescopic rod 1 will inevitably generate a reaction force. At this time, the pressure plate 32 will be pressed into the groove 1 by the reaction force, and will not be able to escape from the groove 1 under its own action. The grooves 1 in different positions also allow the pressure plate 32 to adapt to the downward pressure of different numbers of cables on the pressure plate 32.

[0045] Working principle:

[0046] After the side panels 10 and crossbeams 11 are installed, the cables are passed between the adjacent limiting plates 1 20 and 21, which are not rotatably connected to each other in the middle. The multiple limiting mechanisms form multiple channels for the cables to pass through, thereby separating the cables in the horizontal direction and reducing the possibility of accumulation and entanglement.

[0047] Cables can also be placed on the top of the pressure plate 32, and the pressure plate 32 can be used to achieve vertical separation of the cables. In addition, the pressure plate 32 can press down the limit plate 1 20 and the limit plate 2 21 to change the size of the cable channel, and can further clamp the cables to reduce the shaking of the cables.
