Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to an adjustable cable bridge. Background Art

[0002] Cable trays are used to install and fix cables. When faced with the need to turn the line, they often rely on welding technology to connect the straight sections of the cable tray. This process is not only complex, time-consuming and labor-intensive, but also requires cutting and re-welding the cable tray if the corner angle needs to be adjusted later. This greatly increases maintenance costs and construction difficulty, and reduces project efficiency.

[0003] Chinese patent CN113839359B proposes a cable tray that achieves a flexible connection between two straight slot sections by introducing an external vertical plate. When the angle between the straight slots exceeds a right angle, the flexible plate assembly will bend and extend inward (i.e., inside the cable tray) to adapt to the angle. This phenomenon directly leads to limited available space for the cable, affecting the laying density and flexibility of the cable. More importantly, the direct contact between the flexible plate and the cable may cause friction and wear during the dynamic use of the cable (such as pulling, adjusting position, etc.). In the long run, it will not only damage the cable sheath and affect electrical safety, but also may cause fire and other safety hazards due to the accumulation of debris caused by wear, thereby posing a threat to the stable operation of the entire cable tray system.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0019] like Figure 1 As shown, an adjustable cable tray includes a first straight slot 100 and a second straight slot 200, which are connected by an adjustment slot 1. The adjustment slot includes a first curved slot 12 and a second curved slot 14, which are rotatably connected and locked by a knob 2. This design allows the cable tray to flexibly adjust its angle to adapt to different line layout requirements, improving installation flexibility and convenience.

[0020] In at least one embodiment, the first arc-shaped groove includes a bottom plate, on which an outer arc-shaped sleeve 11 and an inner arc-shaped sleeve 13 are provided, and in cooperation therewith, the second arc-shaped groove includes an inner plate, on which an outer arc-shaped plate 15 and an inner arc-shaped plate 16 are provided, and an insertion groove is provided on the right side of the bottom plate, the insertion groove cooperates with the inner plate, the outer arc-shaped sleeve cooperates with the outer arc-shaped plate, and the inner arc-shaped sleeve cooperates with the inner arc-shaped plate.

[0021] Furthermore, the bottom plate is provided with a rotating shaft 17 near the inner arc sleeve, and the second arc groove is rotatably connected to the rotating shaft. The design of the rotating shaft allows the second arc groove to easily rotate around it, further improving the flexibility and accuracy of the angle adjustment.

[0022] The solution is further refined. When the second curved slot is able to rotate about the axis, the outer curved plate, inner curved plate, and inner layer plate are inserted into the outer curved sleeve, inner curved sleeve, and insertion slot, respectively. This plug-in design enhances the structural strength of the adjustment slot, prevents shaking or deviation during rotation, and ensures the stability and safety of the cable tray.

[0023] In at least one embodiment, a first end plate is provided at the end of the first straight groove, a second end plate is provided on the first arc-shaped groove, and the first end plate and the second end plate are fixedly connected together by bolts.

[0024] In at least one embodiment, a third end plate is provided at the end of the second straight groove, a fourth end plate is provided on the second arc-shaped groove, and the third end plate and the fourth end plate are fixed together by bolts.

[0025] In at least one embodiment, the tops of the first and second straight slots and the adjustment slots are sealed with a cover plate. The cover plate design is not only aesthetically pleasing but also effectively prevents dust and debris from entering the cable tray, protecting the integrity and safety of the cables.

[0026] Furthermore, a plurality of guide rods 18 are provided between the cover plate and the bottom plate, and a plurality of guide wheels 19 are rotatably connected to the guide rods. The provision of the guide rods and guide wheels greatly reduces the friction and resistance of the cable during laying, improves the efficiency and convenience of cable laying, and protects the cable sheath from damage.

[0027] In at least one embodiment, the outer curved plate is provided with a plurality of through-holes, into which the knob end can be inserted and then threaded onto the outer curved sleeve. This design allows the knob to be securely locked to the outer curved plate, preventing the angle from loosening or shifting after adjustment, thereby ensuring the stability and reliability of the cable tray.

[0028] Working method, confirm the required length, angle and installation position of the cable tray. Prepare the components of the first straight slot 100, the second straight slot 200 and the adjustment slot 1. Make sure that all accessories such as bolts, knobs 2, covers, etc. are complete. Connect the end of the first straight slot 100 to the first arc slot of the adjustment slot 1 with bolts, and fix it with the first end plate and the second end plate. Connect the end of the second straight slot 200 to the second arc slot of the adjustment slot 1 with bolts, and fix it with the third end plate and the fourth end plate. Make sure that the connection is tight and not loose. Loosen knob 2 according to the actual line turning requirements. Turn the second arc slot so that it rotates around the rotating shaft 17 to the required angle. During the adjustment process, ensure that the outer arc plate 15 and the outer arc sleeve 11, and the inner arc plate 16 and the inner arc sleeve 13 are tightly matched. After the adjustment is completed, tighten knob 2 to fix the second arc slot in the required position. Lay the cable in the cable tray according to the designed route. During the laying process, be careful to avoid direct contact between the cable and the adjustment groove, and use the guide wheel to guide the cable. After the cable is laid, cover it with the cover to ensure that the cable is completely covered.

[0029] Regularly check the cable tray connections for tightness and knobs for looseness. Clean any dust and debris from the guide wheels to ensure smooth rotation. Repeat the above steps if you need to adjust the angle or replace cables.
