Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a trough-type composite cable tray. Background Technology

[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type. Among them, the trough type is a very common type of cable tray, which consists of supports, brackets, and installation accessories. In order to improve the corrosion resistance of cable trays, anti-corrosion coatings are often sprayed on the surface of the cable trays.

[0003] The height of existing cable trays is usually fixed and cannot be adjusted according to the cable diameter, resulting in low practicality of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a trough-type composite cable tray to solve the problem that cable trays cannot be adjusted according to cable diameter.

[0005] To achieve the above objectives, a trough-type composite cable tray is provided, comprising: a tray base frame; two limiting side plates inserted into the upper surface of the tray base frame; a connecting plate fixedly connected between the two limiting side plates; a driving bolt threadedly connected to the middle of the upper surface of the connecting plate; a partition slidably connected between the two limiting side plates; a rotating column fixedly connected to the lower end of the driving bolt; the rotating column rotatably installed inside the partition; two limiting rods fixedly connected to the upper surface of the partition; the upper ends of both limiting rods penetrate the connecting plate, facilitating workers to adjust the distance between the partition and the tray base frame according to the cable diameter, thus increasing the practicality of the device;

[0006] Two insert blocks are fixedly connected to the lower surfaces of the two limiting side plates. The insert blocks are inserted into the bottom frame of the cable tray. Two mounting slots are opened inside the bottom frame of the cable tray. Two limiting plates are slidably connected inside the two mounting slots. A fitting block is slidably connected between two adjacent limiting plates. The end of the limiting plate away from the fitting block is inserted into the insert block. A fixing bolt is inserted into the fitting block. One end of the fixing bolt is threaded to the inner wall of the mounting slot. By using a separate installation of the limiting side plates and the bottom frame of the cable tray, it is possible to effectively prevent the connecting plates from obstructing the cable laying and improve the convenience of laying.

[0007] According to the aforementioned trough-type composite cable tray, multiple anti-slip lines are fixedly connected to the side of the limiting plate. The multiple anti-slip lines are evenly arranged to facilitate the sliding of the limiting plate by the operator and to facilitate the release of the limiting plate from the insertion block.

[0008] According to the aforementioned trough-type composite cable tray, two limiting rods are symmetrically arranged. The longitudinal section of the limiting rod is T-shaped. The limiting rods can limit the partition and prevent the partition from rotating synchronously with the driving bolt.

[0009] According to the aforementioned trough-type composite cable tray, the longitudinal section of the rotating column is T-shaped, which facilitates the up-and-down movement of the bolt partition.

[0010] According to the aforementioned trough-type composite cable tray, the cross-section of the interlocking block is an isosceles trapezoid, and the end of the limiting plate near the interlocking block is provided with an inclined surface. By cooperating with the inclined surface of the interlocking block and the inclined surface of the limiting plate, it is convenient for the limiting plate to be inserted into the interlocking block when installing the interlocking block.

[0011] According to the aforementioned trough-type composite cable tray, the height of the interlocking block is the same as the width of the mounting groove, and the width of the limiting plate is the same as the mounting groove, which facilitates the stable lateral movement of the limiting plate and the installation of the interlocking block inside the mounting groove.

[0012] According to the aforementioned trough-type composite cable tray, both the bottom frame and the limiting side plate of the tray are made of steel, and the surfaces of the bottom frame and the limiting side plate are coated with anti-corrosion paint to prevent steel corrosion and extend service life.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. The clockwise rotation of the drive bolt facilitates the downward movement of the partition. The limit rod allows for easy positioning of the partition to prevent it from rotating synchronously with the drive bolt. The rotating column facilitates the connection between the drive bolt and the partition, allowing workers to easily adjust the distance between the partition and the bottom frame of the cable tray according to the cable diameter, thus increasing the practicality of the device.

[0015] 2. The insert block facilitates the insertion and installation of the limiting side plate on the bottom frame of the cable tray. By fitting the interlocking block between the two limiting plates, it is easy to push the limiting plate into the insert block to limit the position of the insert block. The interlocking block is easily fixed by the fixing bolt. The separate installation of the limiting side plate and the bottom frame of the cable tray can effectively prevent the connecting plate from obstructing the cable laying and improve the convenience of laying.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] Reference Figure 1-4 This utility model discloses a trough-type composite cable tray, comprising: a cable tray base frame 1, two limiting side plates 2 inserted into the upper surface of the cable tray base frame 1, a connecting plate 3 fixedly connected between the two limiting side plates 2, the connecting plate 3 connecting the two limiting side plates 2 into a whole, a drive bolt 4 threadedly connected to the middle of the upper surface of the connecting plate 3, the drive bolt 4 driving a partition 5 to move up and down, the partition 5 slidably connected between the two limiting side plates 2, the partition 5 fixing the cable, a rotating column 6 fixedly connected to the lower end of the drive bolt 4, the rotating column 6 connecting the partition 5 to the drive bolt 4, the rotating column 6 rotatably installed inside the partition 5, two limiting rods 7 fixedly connected to the upper surface of the partition 5, the limiting rods 7 limiting the partition 5, and the upper ends of both limiting rods 7 penetrating the connecting plate 3;

[0027] Two insert blocks 8 are fixedly connected to the lower surfaces of the two limiting side plates 2. The insert blocks 8 are used to insert into the bottom frame 1 of the cable tray. The insert blocks 8 are inserted into the bottom frame 1 of the cable tray. Two mounting slots 9 are opened inside the bottom frame 1 of the cable tray. Two limiting plates 10 are slidably connected inside the two mounting slots 9. The limiting plates 10 are used to limit the insert blocks 8. A fitting block 11 is slidably connected between two adjacent limiting plates 10. The fitting block 11 is used to limit the limiting plates 10. The end of the limiting plate 10 away from the fitting block 11 is inserted into the insert block 8. A fixing bolt 12 is inserted into the fitting block 11. The fixing bolt 12 is used to fix the fitting block 11. One end of the fixing bolt 12 is threaded to the inner wall of the mounting slot 9.

[0028] Reference Figure 1-2 Two limiting rods 7 are symmetrically arranged. The longitudinal section of the limiting rod 7 is T-shaped. The end of the limiting plate 10 near the interlocking block 11 is provided with an inclined surface. The limiting rod 7 can prevent the partition 5 from rotating with the driven bolt 4.

[0029] Reference Figure 3-5 The height of the interlocking block 11 is the same as the width of the mounting groove 9, and the width of the limiting plate 10 is the same as the width of the mounting groove 9. Multiple anti-slip lines 13 are fixedly connected to the side of the limiting plate 10. The anti-slip lines 13 increase the friction and facilitate the movement of the limiting plate 10 by the staff. The multiple anti-slip lines 13 are evenly arranged. The longitudinal section of the rotating column 6 is T-shaped to ensure that the driving bolt 4 can rotate while preventing the partition 5 from separating from the driving bolt 4. The cross section of the interlocking block 11 is an isosceles trapezoid. The bottom frame 1 of the cable tray and the limiting side plate 2 are both made of steel. The surfaces of the bottom frame 1 of the cable tray and the limiting side plate 2 are coated with anti-corrosion paint to extend the service life of the device.

[0030] Working principle: In use, the operator can first fix the bottom frame 1 of the cable tray, then place the cable inside the bottom frame 1, then insert the plug 8 into the bottom frame 1, then fit the fitting block 11 between the two limiting plates 10, and then insert the fixing bolt 12 into the fitting block 11. The fixing bolt 12 is threaded into the bottom frame 1, which facilitates the fixing of the limiting side plate 2. The limiting side plate 2 and the bottom frame 1 of the cable tray are installed separately, which can prevent the connecting plate 3 from obstructing the cable laying and increase the ease of laying. Then, rotating the bolt 4 will move the partition 5 down to fit with the cable, which makes it easy for the operator to adjust the height between the partition 5 and the bottom frame 1 of the cable tray according to the cable diameter, thus improving the practicality of the device.
