Description

Technical Field

[0001] This invention relates to the field of cable tray technology, and more particularly to a cable tray. Background Technology

[0002] As an important carrier for cable wiring, the structural design and performance of cable trays have a significant impact on the operational safety and service life of cables. However, existing cable trays have some problems and shortcomings.

[0003] First, during installation, cables are prone to contact with cable trays. At the contact points between the cables and the cable trays, especially where the cable harness contacts the cable tray, there is friction between the cable sheath and the metal of the cable tray. Over long-term operation, this may cause wear on the cable sheath, and even further wear down to the inner insulation layer. This may cause local overheating of the cable, and even lead to serious consequences such as cable short circuits and fires.

[0004] Secondly, cable trays are prone to corroding cables when exposed to alternating hot and cold temperatures. Most cable trays are made of metal, and the rate at which these metals expand and contract when the ambient temperature changes is different from that of the cables. If they come into direct contact, it may cause damage to the surface of the cables, further reducing the performance of the cables, and in severe cases, even causing the cables to fail.

[0005] Furthermore, existing cable trays are easy to keep dry. In humid environments, the metal material of cable trays is prone to corrosion, which leads to a decrease in the strength of the cable tray structure. In addition, water accumulation on the surface of the cable tray may also corrode the cables, affecting their service life.

[0006] Finally, existing cable trays are prone to wobbling during splicing and lack pre-fixing functionality. When splicing multiple cable trays, the lack of pre-fixing design makes the cable trays prone to wobbling due to unstable splicing, which not only increases the difficulty of installation work but may also affect the stability and safety of the cable trays.

[0007] The aforementioned problems and shortcomings limit the effectiveness and safety of cable trays, and in severe cases may even threaten the stable operation of the power system. Therefore, it is necessary to improve existing cable trays to solve these problems. Summary of the Invention

[0008] To achieve the above objectives, the present invention provides a cable tray.

[0009] A cable tray includes a cable tray body. A plug is fixedly installed at one end of the cable tray body, and a folded edge is fixed at the other end. The plug is used to insert into the folded edge to match it, and the plug is used to insert into the notch of the folded edge, thereby pre-positioning the cable tray body. Movable slots are provided on both sides of one end of the cable tray body. Mounting rods are movably provided on the inner walls of both sides of the cable tray body. Mounting shafts are rotatably installed at one end of each mounting rod, and one end of each mounting shaft is inserted into a corresponding movable slot. Multiple top rollers are provided inside the cable tray body, and a lifting mechanism is provided inside the cable tray body. When the mounting rods move, the lifting mechanism drives the multiple top rollers to move upwards.

[0010] Furthermore, the lifting mechanism includes multiple fixed rods, which are rotatably mounted on one side of the corresponding mounting rod via pivot pins. The two ends of multiple top rollers are rotatably connected to one end of the corresponding fixed rod, and the other ends of the fixed rods are rotatably mounted on the inner walls of both sides of the cable tray body.

[0011] Furthermore, the other end of the two mounting shafts is fixedly mounted with the same movable block, and a fixed block is fixedly mounted at the bottom of the cable tray body. A threaded rod is provided through one side of the fixed block, and the threaded rod is rotatably connected to the fixed block. One end of the threaded rod passes through the movable block and is threadedly connected to it. Two guide rods are fixedly mounted on one side of the fixed block, and one end of the guide rod passes through the movable block and is slidably connected to it.

[0012] Furthermore, a groove is provided on one side of the insert block, and a slider is slidably arranged in the groove. Multiple guide pins are installed on one side of the slider, and one end of each guide pin passes through one side of the groove and is slidably connected thereto. The other end of each guide pin is fixedly installed with the same pressure plate. A rectangular slot is provided at one end of the cable tray body, and the slider is adapted to the rectangular slot.

[0013] Furthermore, both sides of the slider are provided with circular slots, and each circular slot is provided with a movable pin. One end of each pin is fixedly installed with a spring, and the other end of each spring is fixedly connected to one side of the corresponding circular slot.

[0014] Furthermore, two slide rods are slidably installed on one side of the insert block. A connecting pin is fixedly installed at one end of each slide rod, and the other end of each connecting pin is fixedly installed on one side of the corresponding mounting shaft. The same trapezoidal block is fixedly installed at the other end of the two slide rods. A rubber roller is rotatably provided on one side of the pressure plate, and the rubber roller rolls on one side of the inclined edge of the trapezoidal block.

[0015] Furthermore, slide rails are installed on both sides of the cable tray body, and a sliding plate is slidably installed on one side of each slide rail. Two first mounting holes are opened on one side of the sliding plate. Two third mounting holes and two second mounting holes are opened at both ends of the cable tray body, respectively. The two first mounting holes are respectively adapted to the corresponding second mounting holes.

[0016] Furthermore, positioning blocks are rotatably installed on both sides of the end of the cable tray body away from the slide rail. Two fourth mounting holes are opened on one side of each positioning block. An inclined part is provided on one side of the positioning block, and a protrusion is fixedly installed on one side of the slide plate. The protrusion is used to squeeze the inclined part on the corresponding side of the positioning block to make it rotate. The two fourth mounting holes are respectively adapted to the corresponding third mounting holes.

[0017] Furthermore, the inner wall of the cable tray body is fixed with a plurality of nuts, and the plurality of nuts are respectively coaxially arranged with the corresponding third mounting hole and the corresponding second mounting hole.

[0018] Furthermore, the upper sliding latch of the cable tray body is equipped with a sealing cover.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention, through the design of the top roller, can lift the cable, preventing direct contact between the cable and the metal parts of the cable tray, reducing potential friction and corrosion, and protecting the cable. Simultaneously, the height of the top roller can be adjusted by rotating the mounting rod, allowing for fine-tuning of the cable height as needed.

[0021] 2. The present invention, through the design of the insert block and the folded edge, makes the docking and initial positioning of the cable tray body very simple. Secondly, through the synergistic action of the threaded rod and the movable block, the slider is locked in the rectangular slot for further tightening, thereby achieving a stable connection of the cable tray.

[0022] 3. The present invention, through the sealing cover provided by the sliding clip, can effectively prevent moisture and debris from entering the inside of the cable tray, keep the inside of the cable tray dry, prevent the cable tray from corroding, and thus extend the service life of the cable tray and cables.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0037] like Figures 1-9 As shown, a cable tray includes a cable tray body 1. A plug 8 is fixedly installed at one end of the cable tray body 1, and a folded edge 27 is fixed at the other end. The plug 8 is used to insert into the notch of the folded edge 27 to pre-position the cable tray body 1. Movable slots 28 are provided on both sides of one end of the cable tray body 1. Mounting rods 6 are movably installed on the inner walls of both sides of the cable tray body 1. Mounting shafts 18 are rotatably installed at one end of each mounting rod 6, and one end of each mounting shaft 18 is inserted into the corresponding movable slot 28. Multiple top rollers 2 are provided inside the cable tray body 1, and a lifting mechanism is provided inside the cable tray body 1. When the mounting rods 6 move, the lifting mechanism drives the multiple top rollers 2 to move upwards. When installing the cable tray body 1, the plug 8 is first inserted into the notch of the folded edge 27, and then the lifting mechanism moves the top rollers 2 upwards. At this time, the cable is lifted and suspended, achieving cable height adjustment and preventing cable contact with the cable tray.

[0038] The lifting mechanism includes multiple fixed rods 7, which are rotatably mounted on one side of the corresponding mounting rod 6 via pivot pins. The two ends of multiple top rollers 2 are rotatably connected to one end of the corresponding fixed rod 7, and the other ends of the fixed rods 7 are rotatably mounted on the inner walls of both sides of the cable tray body 1. When the movable block 13 moves along the movable groove 28, the mounting rod 6 moves synchronously. Under the action of the fixed rods 7, the mounting rod 6 rotates, thereby causing the top rollers 2 to move upward synchronously.

[0039] The other ends of the two mounting shafts 18 are fixedly mounted with the same movable block 13. The bottom of the cable tray body 1 is fixedly mounted with a fixed block 11. A threaded rod 14 is provided through one side of the fixed block 11. The threaded rod 14 is rotatably connected to the fixed block 11. One end of the threaded rod 14 passes through the movable block 13 and is threadedly connected to it. Two guide rods 12 are fixedly mounted on one side of the fixed block 11. One end of the guide rod 12 passes through the movable block 13 and is slidably connected to it. Rotating the threaded rod 14 drives the movable block 13 to move along the movable groove 28.

[0040] A groove 23 is provided on one side of the insert block 8, and a slider 9 is slidably mounted in the groove 23. Multiple guide pins 20 are installed on one side of the slider 9. One end of each guide pin 20 passes through one side of the groove 23 and is slidably connected to it. The other end of each guide pin 20 is fixedly mounted with the same pressure plate 19. A rectangular slot 26 is provided at one end of the cable tray body 1. The slider 9 is adapted to the rectangular slot 26. Circular slots 21 are provided on both sides of the slider 9, and pins 22 are movably mounted in each circular slot 21. A spring 25 is fixedly mounted on one end of each pin 22. The other end of each spring 25 is fixedly connected to one side of the corresponding circular slot 21. When the movable block 13 moves, the slide rod 16 moves at the same time and drives the trapezoidal block 15 to squeeze the pressure plate 19, thereby locking the slider 9 into the rectangular slot 26 for limiting. At the same time, the pins 22 will pop out under the action of the springs 25 and lock on both sides of the rectangular slot 26, thereby further locking and completing the pre-positioning.

[0041] Two slide rods 16 are slidably installed on one side of the insert block 8. One end of each slide rod 16 is fixedly installed with a connecting pin 17. The other end of each connecting pin 17 is fixedly installed on one side of the corresponding mounting shaft 18. The other end of each slide rod 16 is fixedly installed with the same trapezoidal block 15. A rubber roller 24 is rotatably provided on one side of the pressure plate 19. The rubber roller 24 rolls on the inclined side of the trapezoidal block 15. When the trapezoidal block 15 presses the pressure plate 19, the rubber roller 24 reduces the friction.

[0042] Both sides of the cable tray body 1 are equipped with slide rails 29. A sliding plate 30 is slidably mounted on one side of each slide rail 29. Two first mounting holes 31 are provided on one side of each sliding plate 30. Two third mounting holes 32 and two second mounting holes 10 are provided at each end of the cable tray body 1. The two first mounting holes 31 are respectively matched with the corresponding second mounting holes 10. Positioning blocks 3 are rotatably mounted on both sides of the end of the cable tray body 1 away from the slide rails 29. Two fourth mounting holes 34 are provided on one side of each positioning block 3. An inclined portion is provided on one side of each positioning block 3. A protrusion 33 is fixedly mounted on one side of the sliding plate 30. The protrusion 33 is used for extrusion... Press the inclined part on one side of the corresponding positioning block 3 to make it rotate. The two fourth mounting holes 34 are respectively adapted to the corresponding third mounting holes 32. Multiple nuts 5 are fixed on the inner wall of the cable tray body 1, and the multiple nuts 5 are respectively coaxially set with the corresponding third mounting hole 32 and the corresponding second mounting hole 10. After docking, move the sliding plate 30 so that the first mounting hole 31 and the second mounting hole 10 coincide. At the same time, the protrusion 33 presses the inclined part of the positioning block 3 to make it flip, so that the third mounting hole 32 and the fourth mounting hole 34 coincide. Then, use the matching nuts 5 and bolts to lock the two cable tray bodies 1 to complete the installation.

[0043] The upper sliding clip of the cable tray body 1 is equipped with a sealing cover 4. The sealing cover 4 effectively prevents moisture and debris from entering the inside of the cable tray, keeps the inside of the cable tray dry, and prevents the cable tray from corroding.

[0044] Working principle: When installing the cable tray body 1, first insert the plug 8 into the notch of the folded edge 27, then rotate the threaded rod 14 to drive the movable block 13 to move along the movable groove 28. At the same time, the mounting rod 6 moves synchronously. Under the action of the fixed rod 7, the mounting rod 6 rotates, so the top roller 2 moves upward synchronously. At this time, the cable will be lifted and suspended in the air, realizing the height adjustment of the cable and preventing the cable from contacting the cable tray. While the movable block 13 moves, the sliding rod 16 moves at the same time and drives the trapezoidal block 15 to press the pressure plate 19. This allows the slider 9 to be inserted into the rectangular slot 26 for positioning. At the same time, the pin 22 will pop out under the action of the spring 25 and lock onto both sides of the rectangular slot 26, thereby further locking and completing the pre-positioning. After the docking is completed, the sliding plate 30 is moved so that the first mounting hole 31 and the second mounting hole 10 coincide. At the same time, the protrusion 33 presses the inclined part of the positioning block 3 to make it flip, so that the third mounting hole 32 and the fourth mounting hole 34 coincide. Then, the mating nut 5 is used to lock the two cable tray bodies 1 with bolts, thereby completing the installation.
