Description

Technical Field

[0001] This utility model relates to the field of cable tray installation technology, specifically a direct burial device for vertical cable trays. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of various industrial, commercial, and infrastructure construction projects, the scale of power system installations is becoming increasingly large. Cable trays, as devices that effectively support, protect, and manage cable lines, are widely used in numerous fields such as construction, factories, and rail transportation. In actual wiring scenarios, vertical cable trays play a crucial role. For example, in high-rise buildings, they undertake the important task of orderly transmitting power and communication cables between floors, ensuring the building's power consumption and information transmission needs. In the past, the installation of vertical cable trays often involved surface mounting or fixing them to conventional foundations before construction. While surface mounting facilitates construction and subsequent maintenance, it suffers from poor aesthetics and space occupation. Conventional foundation-fixed installation methods, however, are unreliable in complex underground environments and when faced with the need for long-term stable support of vertical cable weights and resistance to various external forces (such as soil settlement and lateral compression). This can easily lead to cable tray tilting or displacement, affecting the normal use of cables and even causing safety hazards. Given the limitations of the above installation methods, especially in some new projects, there is a desire to arrange vertical cable trays in a more concealed, stable manner that is better adapted to underground environments. This has led to the development of the direct burial installation concept.

[0003] However, existing direct-buried installations for vertical cable trays have the following disadvantages: (1) Currently, in practical use, this device is mostly operated and used in an integrated form. Although this integrated design has its unique advantages, it is not very convenient in terms of installation and angle adjustment. For example, it is difficult to achieve the ideal installation effect in a specific space, thus affecting the overall user experience and work efficiency; (2) At present, in the actual use of the device, the connection between the various components is mostly fixed by bolts. Although this fixing method is simple and easy to operate, after long-term use, the bolts may gradually loosen due to vibration, environmental factors or material fatigue. Once the bolts loosen, the connection of the entire device will no longer be firm, thus causing the overall structure of the device to be unstable. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a direct burial device for vertical cable trays, which solves the problems mentioned in the background art, such as the integrated form being inconvenient to install under special circumstances and the bolt fixing being prone to loosening later.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A direct burial device for vertical cable trays includes a quick-connect assembly, a main body, a splicing body, and a fixing assembly; the quick-connect assembly includes a first servo motor, a first lead screw, a stop plate, a first spring, a middle plate, and a second spring. The output shaft of the first servo motor is connected to a first lead screw via a spline. The first lead screw is threadedly connected to two abutments. One side of each abutment is slidably connected to a middle plate, and the two abutments are fixedly connected to each other by a first spring. A second spring is fixedly connected to the other side of each abutment. The main body is located on one side of the second spring, and the splicing main body is snapped onto the other side of the main body. A connecting block is fixedly connected to the side of the splicing main body closest to the main body. A cover plate is slidably connected to the surface of the main body, and the fixing assembly is located on the surface of the cover plate. The fixing assembly includes a second servo motor, a second lead screw, a snap-fit ​​block, a connecting rod, a third servo motor, and a third lead screw. The system comprises a spring rod, a side clamping plate, and an outer rod. The output shaft of the second servo motor is connected to a second lead screw via a spline. A clamping block is threaded onto the second lead screw. A connecting rod is located on one side of the second lead screw, and one end of the connecting rod is fixedly connected to the hollow outer rod. The outer rod houses the third servo motor, and its output shaft is connected to a third lead screw via a spline. A spring rod is threaded onto the third lead screw, and the spring rod is located within the internal cavity of the outer rod. A side clamping plate is rotatably connected to one side of the spring rod, and the side clamping plate is rotatably connected to the outer rod. Slots adapted to the side clamping plate are provided on both sides of the outer rod.

[0006] Furthermore, the quick-connect assembly drives the first lead screw to rotate via the first servo motor, causing the two abutments to slide along the middle plate. The abutments are then moved inward by the elastic force of the first spring to clamp the connecting block, thereby achieving quick connection and fixation between the main body and the splicing body.

[0007] Furthermore, the fixing component drives the third lead screw to rotate via the third servo motor, causing the spring rod to move along the thread direction and push the side clamping plate to rotate around the rotation point between itself and the outer rod, thereby causing the side clamping plate to unfold outward from the slot of the outer rod to clamp the external device.

[0008] Furthermore, the fixing component also drives the second lead screw to rotate via the second servo motor, causing the locking block to move along the thread direction to secure the top of the device.

[0009] Furthermore, the shape of the connecting block is adapted to the snap-fit ​​groove of the main body, and after the connecting block is inserted into the main body, it is locked by the clamping of the quick-connect assembly.

[0010] The beneficial effects of this utility model are as follows: 1. This direct-buried device for vertical cable trays, through the configuration of a first servo motor, a first lead screw, a stop plate, and a first spring, enables the entire device to be connected and used through a modular design. By inserting the main body to be spliced ​​into the splicing body through the setting of the connecting block, the first servo motor drives the first lead screw to rotate. The stop plates on both sides of the rotating first lead screw move inward to abut and clamp the connecting block, thus enabling the main body and the splicing body to be quickly connected and used.

[0011] 2. This direct-buried device for vertical cable trays, through the setting of a third servo motor, a third lead screw, a spring rod, and side clamping plates, makes the overall device more stable and secure. The third servo motor drives the third lead screw to rotate, and the rotation of the third lead screw drives the threaded spring rod, so that the side clamping plates connected to the spring rod can be unfolded to both sides. This can lock the connected device in place, avoiding the loosening that is easily caused by bolted connections. Attached Figure Description
