Description

Technical Field

[0001] This utility model relates to the field of cable laying equipment technology, and in particular to a device for laying horizontal cable trays. Background Technology

[0002] Cables are an important basic material in electrical engineering. Cable procurement costs are high, laying time is long, and overall costs are high, resulting in high costs in electromechanical installation.

[0003] When cables are laid in horizontal cable trays in civil buildings, commonly used cable laying traction equipment such as winches cannot be used. The main reason is that the operating surface of the cable tray is narrow, and there is a deflection angle between the traction force of the cable pulling equipment and the direction of cable travel. In addition, the cable has a large cross-sectional area and heavy weight. When the cable is laid in the cable tray, the surrounding cable group that has already been laid will exert continuous lateral pressure on the cable being laid, causing interlayer displacement of the inner layers of the cable, resulting in internal damage to the cable and affecting the service life of the cable. During the laying process, the cable is very prone to jamming or damage.

[0004] If manual laying is the primary method of cable laying, there are drawbacks such as low cable laying efficiency and high labor costs.

[0005] In conclusion, the existing technology has obvious defects in practical use and needs to be improved. Utility Model Content

[0006] To address the aforementioned shortcomings, the purpose of this utility model is to provide a device for laying horizontal cable trays. This device can limit and guide the cable around the area being laid, ensuring that the cable's position is restricted during use. This effectively facilitates the laying of the cable and reduces damage to the cable during the laying process.

[0007] To achieve the above objectives, this utility model provides a device for laying horizontal cable trays, comprising: A main ring sleeve is fitted over the outside of the cable. One side of the main ring sleeve has two mounting parts that are fixedly installed on the cable. The main ring sleeve is fixed to the cable by the action of the mounting parts. The side guide is provided on the outer wall of the main ring sleeve, and the side guide guides and buffers the force on both sides of the cable. Limiting components are provided on the upper and lower sides of the main ring sleeve to restrict and guide the upper and / or lower positions of the cable. The limiting components limit the upper and / or lower positions of the cable during the laying process. A traction mechanism is installed at the outlet of the horizontal cable tray, which pulls and threads the end of the cable.

[0008] In one embodiment, the side guide includes: Telescopic outer rods are installed on both sides of the main ring sleeve, and the telescopic outer rods are provided with sliding holes inside; A telescopic inner rod is slidably connected inside the sliding hole, and a thrust spring is provided between the telescopic inner rod and the bottom of the sliding hole. The telescopic inner rod extends out of the sliding hole under the action of the thrust spring.

[0009] In one embodiment, the end of the telescopic outer rod is provided with a threaded portion, and the side wall of the main ring sleeve is provided with a threaded hole corresponding to the threaded portion. The telescopic outer rod is installed on the threaded hole through the threaded portion.

[0010] In one embodiment, the end of the telescopic inner rod is rotatably connected to a guide roller, which, under the action of a thrust spring, constantly abuts against both sides of the predetermined laying position, thereby restricting the laying position of the cable.

[0011] In one embodiment, the limiting member includes: The limiting outer rod is installed on the side wall of the main ring sleeve through a screw connection, and the main ring sleeve is provided with a threaded hole corresponding to the screw connection; An inner limiting rod is disposed inside the outer limiting rod, and the inner limiting rod restricts the position of the main ring to the bottom and / or top.

[0013] In one embodiment, a limiting rod is rotatably connected to the bottom of the inner limiting rod, the limiting rod passing through a rotating hole at the bottom of the inner limiting rod, and both ends of the limiting rod abutting the bottom of a predetermined installation position.

[0014] In one embodiment, extension rods are slidably connected to both sides of the limiting rod, and an extension spring is provided between the extension rod and the limiting rod, the extension spring extending the extension rod beyond the limiting rod.

[0015] In one embodiment, mounting plates are provided on both sides of the mounting part, the mounting plates are fixed by bolts, and the two mounting parts are connected by bolts and clamp the cable.

[0016] In one embodiment, the front end of the mounting part is provided with a guide bevel, the interior of the mounting part is provided with a clamping bevel, and the inner wall of the clamping bevel is provided with a plurality of clamping protrusions that cooperate with each other to clamp the cable.

[0017] This utility model provides a device for laying horizontal cable trays, comprising: The main ring sleeve is fitted over the outside of the cable. One side of the main ring sleeve has two mounting parts that are fixedly installed on the cable. The main ring sleeve is fixed to the cable under the action of the mounting parts, so that when the cable needs to be laid, the cable can be pulled by the traction mechanism, and the entire main ring sleeve can be driven into the inside of the cable tray. The main ring sleeve protects the cable and prevents the cable from being damaged due to laying problems during the laying process. The side guide component installed on the outer wall of the main ring sleeve guides and buffers the force on both sides of the cable, ensuring that the horizontal force and position of the cable are guided during the laying process, thereby effectively protecting the cable and preventing damage to the cable during the laying process.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figure 1 and Figure 2 This utility model provides a device for laying horizontal cable trays. The device includes a main ring sleeve 1, which is fitted over the cable. Two mounting parts 2 are fixedly installed on the cable on one side of the main ring sleeve 1. The main ring sleeve 1 is fixed to the cable by the mounting parts 2, ensuring that when laying the cable, pulling the end of the cable will move the entire main ring sleeve 1 into the cable tray. The main ring sleeve 1 protects the cable and prevents damage during laying. Side guides are provided on the outer wall of the main ring sleeve 1 to guide and buffer the forces on both sides of the cable, ensuring smooth laying. The horizontal force and position of the cable are guided during laying, effectively protecting the cable and preventing damage during installation. Limiting devices are installed on the upper and lower sides of the main ring 1 to restrict and guide the upper and / or lower positions of the cable. These limiting devices limit the upper and / or lower positions of the cable during installation, effectively limiting the top and bottom of the cable and preventing damage to the underlying cable layer, thus ensuring normal cable laying. A traction mechanism (existing technology, not shown in the figure) is installed at the outlet of the horizontal cable tray. This traction mechanism pulls the cable end for threading, thereby automatically pulling the cable.

[0021] In one embodiment, the side guide includes: The telescopic outer rods 5 are installed on both sides of the main ring sleeve 1. The telescopic outer rods 5 are provided with sliding holes to ensure the normal installation and sliding effect of the telescopic inner rod 6 and the telescopic outer rods 5. A telescopic inner rod 6 is slidably connected inside the sliding hole. A thrust spring 13 is provided between the telescopic inner rod 6 and the bottom of the sliding hole. The telescopic inner rod 6 extends out of the sliding hole under the action of the thrust spring 13. By setting the thrust spring 13, it is ensured that the outer end of the telescopic inner rod 6 can always abut against both sides of the predetermined position, which can effectively buffer the force at both ends of the cable.

[0022] Specifically, in combination Figure 1 , Figure 2 and Figure 3To ensure proper installation of the telescopic outer rod 5, a threaded portion 51 is provided at the end of the telescopic outer rod 5. The side wall of the main ring sleeve 1 is provided with a threaded hole 11 corresponding to the threaded portion 51. The telescopic outer rod 5 is installed on the threaded hole 11 through the threaded portion 51, ensuring that the telescopic outer rod 5 can be installed in the corresponding position during use and tightened directly to the corresponding position when not in use or when maintenance is required. This effectively ensures the quick installation and disassembly of the telescopic outer rod 5. The end of the telescopic inner rod 6 is rotatably connected to a guide roller. Under the action of the thrust spring 13, the guide roller is always in contact with both sides of the predetermined laying position, thus restricting the laying position of the cable. This ensures that when the traction mechanism pulls the cable, the impact force and wear at both ends of the cable can be buffered by the action of the guide roller and the thrust spring 13, thereby reducing friction during cable laying and effectively protecting the cable.

[0023] In one embodiment, the limiting member includes: The limiting outer rod 7 is installed on the side wall of the main ring sleeve 1 through a screw connection. The main ring sleeve 1 is provided with a threaded hole 11 corresponding to the screw connection to ensure the normal installation of the limiting outer rod 7. At the same time, the limiting parts at the top or bottom of the main ring sleeve 1 can be selectively installed according to the needs during use, so as to adapt to different usage requirements. The inner limiting rod 10 is disposed inside the outer limiting rod 7. The inner limiting rod 10 restricts the position of the main ring sleeve 1 to the bottom and / or top, thereby limiting the vertical force and buffering of the cable during use, preventing damage to the insulation layer of the bottom cable during transportation, and thus effectively protecting the cable at the bottom and during transportation.

[0024] Specifically, combining 3 and Figure 5To prevent cable ends from compressing and damaging the bottom cable layer during cable laying, an adjustment hole is provided inside the outer limiting rod 7. The inner limiting rod 10 is screwed into the adjustment hole via a threaded flange 101, allowing adjustment of the supporting height of the limiting component to accommodate different sizes of cable trays and different cable layers. A limiting rod 8 is rotatably connected to the bottom of the inner limiting rod 10. The limiting rod 8 passes through a rotating hole 102 at the bottom of the inner limiting rod 10. By setting the limiting rod 8, it is ensured that the limiting rod 8 can support at least two cables, thereby limiting the force on the bottom of the cables and preventing damage to the cables. During the transport process, the cable enters between two cables, causing friction or squeezing damage. This further guides and protects the laid cables. The two ends of the limiting rod 8 abut against the bottom of the predetermined installation position. Extending rods 9 are slidably connected to both sides of the limiting rod 8. An extension spring 12 is provided between the extension rod 9 and the limiting rod 8. The extension spring 12 extends the extension rod 9 out of the limiting rod 8. By setting the extension rod 9, it is ensured that the entire extension rod 9 and the limiting rod 8 can be abutted against the top of the entire cable layer, thereby preventing damage to the lower cable insulation, distributing the stress evenly across the entire cable layer, and preventing excessive stress in some areas from damaging the cable.

[0025] In one embodiment, see Figure 4 The mounting part 2 has mounting plates 3 on both sides, which are fixed by bolts. The mounting plates 3 have mounting holes 4 for bolts to pass through, thus ensuring the fixation of the mounting plates 3. The two mounting parts 2 are connected by bolts and clamp the cable, ensuring that the cable can move synchronously with the entire main ring sleeve 1 during transportation. This guides the cable head, preventing damage to the cable layer and preventing the cable head from abrading the cable tray during transportation. The front end of the mounting part 2 has a guide bevel 22, and the inside of the mounting part 2 has a clamping bevel to ensure the insertion effect of the mounting part 2 and prevent large resistance during insertion. The inner wall of the clamping bevel has several clamping protrusions 21 that cooperate with each other to clamp the cable. By setting the clamping protrusions 21, the clamping force between the mounting part 2 and the cable is ensured, the normal clamping effect of the cable is guaranteed, and the synchronous movement of the cable and the main ring sleeve 1 is achieved.

[0026] When using, combine Figures 1-5First, the corresponding cable tray is laid. Then, the corresponding main ring sleeve 1 is fixedly installed to the end of the cable. Then, the cable head is pulled by the traction mechanism. Before pulling, the position and quantity of the side guide and limiting parts are confirmed by the operator. The side guide is used to buffer and guide the lateral force inside the cable tray, which can effectively guide the side of the cable. At the same time, the limiting parts guide and buffer the vertical force of the cable during the transportation process, which can guide the overall cable laying process, reduce the friction of the cable and the destructive force on the cable layer during the laying process, and thus realize the automatic and fast laying of the cable.

Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
