Description

Technical Field

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

[0002] The production of wires and cables begins with the processing of the conductor. Insulation, shielding, cabling, and sheathing are added layer by layer to the outside of the conductor to make wire and cable products. Wires and cables are mainly made through three processes: drawing, stranding, and wrapping.

[0003] On a cable processing production line, when cables are transported directly from one processing device to another, the transport distance is sometimes long. To avoid friction between the cable and the ground, the cable is supported by a bracket. The bracket usually supports the cable with a rotating roller. During the cable transport process, if the tension at the unloading end is too small and the tension at the take-up end is too large, the cable will become loose. After the cable becomes loose, it will slide between itself and the rotating roller, and it is easy to separate from the rotating roller, which will cause the rotating roller to become entangled with the support frame. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology where the cable slips between itself and the rotating roller after it loosens, easily separates from the rotating roller, and causes entanglement between the rotating roller and the support frame, and therefore proposes a cable bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable tray is designed, comprising a movable frame, an electric telescopic rod fixedly connected to the upper end of the movable frame, a mounting frame fixedly connected to the telescopic end of the electric telescopic rod, a support roller rotatably connected to the mounting frame, two parallel first mounting plates fixedly connected to one side of the movable frame, a first rotating roller rotatably connected between the two first mounting plates, a first pressure sensing plate connected to the first rotating roller, and two parallel second mounting plates fixedly connected to the other side of the movable frame, a second rotating roller rotatably connected between the two second mounting plates, a second pressure sensing plate connected to the second rotating roller.

[0007] Preferably, guide plates are fixedly connected to both sides of the bottom end of the mounting frame, and sliding grooves are provided on both sides of the movable frame, with one end of each guide plate slidably connected to the corresponding sliding groove.

[0008] Preferably, the support roller has a V-shaped groove.

[0009] Preferably, the upper end of the mounting frame is fixedly connected to an anti-deviation mechanism, which includes two symmetrically arranged fixing rods. The two symmetrically arranged bottom fixing rods are fixedly connected to the upper end of the mounting frame, and one end of each fixing rod is rotatably connected to a rotating plate. The V-groove is located between the two rotating plates.

[0010] Preferably, a cleaning mechanism for cleaning the V-groove is fixedly connected to the mounting frame. The cleaning mechanism includes an elastic support member connected to the mounting frame. A cleaning block is provided at the upper end of the elastic support member, and the cleaning block contacts the bottom end of the V-groove.

[0011] Preferably, the cleaning block is a sponge cleaning block.

[0012] Preferably, the elastic support includes a spring, one end of which is fixedly connected to the upper end of the mounting bracket, and the other end of which is fixedly connected to a movable plate. The upper end of the movable plate has a groove, and a cleaning block is provided on the groove. Guide rods are fixedly connected to both sides of the bottom end of the movable plate, and each guide rod is slidably inserted into the mounting bracket.

[0013] Preferably, the movable plate and the guide rod are an integral structure.

[0014] The cable tray proposed in this utility model has the following advantages:

[0015] When the cable loosens and separates from the first and second pressure sensors, the electric telescopic rod drives the support roller to move upward again through the mounting frame, causing the cable to re-press the first and second pressure sensors, thereby maintaining tension and ensuring that the cable is always taut during transportation, preventing it from detaching from the support roller.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A cable tray includes a movable frame 1, an electric telescopic rod 2 fixedly connected to the upper end of the movable frame 1, a mounting frame 3 fixedly connected to the telescopic end of the electric telescopic rod 2, a support roller 4 rotatably connected to the mounting frame 3, two parallel first mounting plates 5 fixedly connected to one side of the movable frame 1, a first rotating roller 6 rotatably connected between the two first mounting plates 5, a first pressure sensor 7 connected to the first rotating roller 6, two parallel second mounting plates 8 fixedly connected to the other side of the movable frame 1, a second rotating roller 9 rotatably connected between the two second mounting plates 8, a second pressure sensor 10 connected to the second rotating roller 9, guide plates 11 fixedly connected to both sides of the bottom end of the mounting frame 3, grooves 12 opened on both sides of the movable frame 1, one end of each guide plate 11 slidably connected to the corresponding groove 12, and a V-groove 13 opened on the support roller 4.

[0023] Work process:

[0024] One end of the cable passes through the bottom of the second rotating roller 9, the top of the V-groove 13, and the bottom of the first rotating roller 6 in sequence. After the electric telescopic rod 2 is powered on, it drives the mounting frame 3 to move upward. The mounting frame 3 drives the guide plate 11 to slide along the slide groove 12. Under the cooperation of the guide plate 11 and the slide groove 12, the mounting frame 3 moves smoothly.

[0025] Mounting bracket 3 drives support roller 4 to move upward. Support roller 4 lifts the cable upward and tightens it. After the cable is tightened, it will squeeze the bottom end of the first pressure sensor 7 and the second pressure sensor 10. The pressure value detected by the first pressure sensor 7 and the second pressure sensor 10 can determine whether the cable is in full contact with the second rotating roller 9.

[0026] When the cable loosens and separates from the first pressure sensor 7 and the second pressure sensor 10, the electric telescopic rod 2 drives the support roller 4 to move upward again through the mounting frame 3, so that the cable re-presses the first pressure sensor 7 and the second pressure sensor 10, thereby maintaining a taut state. By monitoring the values ​​of the pressure sensors, the tension of the cable can be judged in real time. If the cable loosens, it pushes the support roller 4 to move upward, ensuring that the cable is always in a taut state during the transportation process and avoiding separation from the support roller 4.

[0027] Example 2: When the cable is limited by the V-groove 13, the cable is easily separated from the cable, reducing the limiting effect. (Refer to...) Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the upper end of the mounting frame 3 is fixedly connected to an anti-deviation mechanism 14. The anti-deviation mechanism 14 includes two symmetrically arranged fixing rods 141. The two symmetrically arranged bottom fixing rods 141 are fixedly connected to the upper end of the mounting frame 3. One end of each fixing rod 141 is rotatably connected to a rotating plate 142. The V-groove 13 is located between the two rotating plates 142.

[0028] The fixing rod 141 fixes the rotating plate 142. The cable is located between the two rotating plates 142. The two rotating plates 142 limit the cable to prevent the cable from separating from the V-groove 13 and improve the limiting effect of the cable.

[0029] Example 3: When the cable is limited by the V-groove 13, debris on the cable easily adheres to the V-groove 13, thereby increasing the friction between the cable and the V-groove 13. (Refer to...) Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a cleaning mechanism 15 for cleaning the V-groove 13 is fixedly connected to the mounting frame 3. The cleaning mechanism 15 includes an elastic support member 151, which is connected to the mounting frame 3. A cleaning block 152 is provided at the upper end of the elastic support member 151. The cleaning block 152 is a sponge cleaning block, and the cleaning block 152 is in contact with the bottom end of the V-groove 13.

[0030] The elastic support 151 includes a spring 1511. One end of the spring 1511 is fixedly connected to the upper end of the mounting bracket 3, and the other end of the spring 1511 is fixedly connected to a movable plate 1512. A groove 1513 is provided at the upper end of the movable plate 1512, and a cleaning block 152 is provided on the groove 1513. Guide rods 1514 are fixedly connected to both sides of the bottom end of the movable plate 1512. Each guide rod 1514 is slidably inserted into the mounting bracket 3. The movable plate 1512 and the guide rods 1514 are an integral structure.

[0031] The cleaning block 152 presses against the V-groove 13, and the cleaning block 152 presses down on the movable plate 1512. The movable plate 1512 moves smoothly under the guidance of the guide rod 1514. After the movable plate 1512 moves down, it presses against the spring 1511. The spring 1511 generates elastic force after being pressed. The elastic force generated by the spring 1511 pushes the movable plate 1512 upward, so that the cleaning block 152 and the V-groove 13 are in close contact. After the support roller 4 rotates, the V-groove 13 and the cleaning block 152 slide relative to each other. The cleaning block 152 cleans the V-groove 13 to prevent debris from sticking to the V-groove 13.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
