Description

Technical Field

[0001] This utility model relates to the field of ring network boxes, and in particular to a primary and secondary integrated ring network box fixing device. Background Technology

[0002] A ring main unit (RMU) is an electrical device consisting of a set of power transmission and distribution equipment housed in a metal or non-metal insulated enclosure, or assembled into a modular ring main unit. It offers advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. The integrated primary and secondary ring main unit is an improvement upon the traditional RMU. The primary circuit is the main circuit, and the secondary circuit is the control circuit for the primary circuit. The primary circuit refers to the circuit formed by the interconnection of electrical equipment directly involved in the generation, transmission, transformation, and use of electrical energy. The secondary circuit refers to the circuit formed by the interconnection of equipment that protects, measures, controls, and meters the primary circuit equipment according to a specific logical relationship. RMUs are widely used in power plants, urban residential areas, high-rise buildings, large public buildings, factories, and other substations and prefabricated substations.

[0003] The primary and secondary integrated ring network boxes are mostly used outdoors. Due to their large size, they need to be lifted and fixed by a crane. During the lifting and fixing process, it is necessary to align too many positioning holes to determine the position, which requires high lifting accuracy. The swaying generated during the process cannot be avoided in time, which makes the lifting process time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a primary and secondary integrated ring network box fixing device, which solves the problem of time-consuming and labor-intensive installation of existing ring network boxes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A primary and secondary integrated ring gabion fixing device includes a base plate, on which a slide rail is provided. The ring gabion is slidably mounted on the slide rail via a pulley block. A positioning element is installed on the outside of the slide rail, and the positioning element locks the pulley block.

[0007] The pulley block includes pulleys, which are mounted on a connecting shaft via a central cylinder, and the connecting shaft is fixed to the bottom of the ring network box;

[0008] The positioning component includes a slider, which is installed on the outside of the slide rail. A positioning bushing is fixed on the slider, and a positioning bolt passes through the positioning bushing and the central cylinder and is limited by a nut.

[0009] The pulley system consists of four pulleys, with each pulley system containing two pulleys, and the two pulleys of each pulley system are located on opposite sides of the connecting shaft.

[0010] Each side has two sets of slide rails, which are set on the same track block. The two pulleys of each pulley set are respectively set on the corresponding slide rails.

[0011] The slider is fixedly mounted on the base plate; or two protruding plates are spaced apart on the base plate outside the slide rail, and the slider is slidably mounted between the two protruding plates; the upper end of the slider is fixed with screws on the left and right, and nuts are screwed into the screws and rubbed and locked with the upper surface of the protruding plates.

[0012] The upper surface of the convex plate is higher than the upper surface of the slider.

[0013] Side plates are fixed on the base plate, and the side plates limit the front and rear movement of the ring mesh box.

[0014] The side plate is L-shaped and has reinforcing ribs at the corners.

[0015] This utility model provides a primary and secondary integrated ring gabion fixing device, which has the following technical effects:

[0016] 1. The smooth movement of pulleys on the slide rails significantly simplifies the displacement process of the ring main unit. The coordinated operation of the two pulleys on the two slide rails not only ensures the stability of the ring main unit during movement but also serves as initial positioning. This allows installers to more easily and accurately push the ring main unit to the designed position, reducing the workload of adjusting its position and correcting its direction.

[0017] 2. After the ring main unit is positioned correctly, place the slider between the two convex plates. The slider should be able to slide freely between the convex plates, ensuring that the positioning sleeve and the central axis of the pulley block are concentric. Then, pass the positioning bolt through the positioning sleeve and the pulley block, and finally screw the nut into the positioning bolt to link the positioning component and the pulley block together. This fixing method is ingeniously designed, simple to operate, and greatly reduces installation difficulty and improves work efficiency. It also facilitates later maintenance, reducing maintenance costs and time. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] Figure 1 This is a schematic diagram of the structure of this utility model.

[0020] Figure 2 This is a cross-sectional view of the present invention.

[0022] Figure 4 This is a schematic diagram of the positioning component in this utility model.

[0023] In the figure: base plate 10, ring mesh box 11, track block 12, slide rail 13, connecting shaft 14, pulley 15, central shaft cylinder 16, positioning bolt 17, protruding plate 18, slider 19, positioning bushing 20, screw 21, nut 22, side plate 23, reinforcing rib 24. Detailed Implementation

[0024] like Figure 1 As shown, a primary and secondary integrated ring network box fixing device includes a base plate 10, with the left and right edges of the base plate 10 fixed by expansion bolts. Track blocks 12 are symmetrically arranged on the left and right sides of the upper surface of the base plate 10, and each track block 12 is provided with two slide rails 13. A pulley assembly is installed below the ring network box 11, and the pulley assembly is slidably mounted on the slide rails 13.

[0025] like Figure 2-3 As shown, this device is equipped with a total of four pulley groups. Each pulley group includes a connecting shaft 14 and a central shaft cylinder 16. The upper end of the connecting shaft 14 is fixed to the bottom of the ring mesh box 11, and the lower end of the connecting shaft 14 is provided with a through hole. Pulleys 15 are provided on both the left and right sides of the connecting shaft 14. The connecting shaft 14 and the pulleys 15 are both sleeved on the central shaft cylinder 16, and the pulleys 15 can rotate on the central shaft cylinder 16.

[0026] When installing the positioning ring network box 11, the ring network box 11 is first placed on the slide rail 13 via a pulley system. This allows the ring network box 11 to be moved during installation, facilitating its placement in the designated position. Each pulley system has two pulleys 15, corresponding to two slide rails 13, which serves as initial positioning and facilitates the installation of the ring network box 11.

[0027] In summary, the smooth movement of pulley 15 on slide rail 13 significantly simplifies the displacement process of the ring network box 11. Compared to traditional manual handling or mechanical hoisting, this method can move the ring network box 11 to the designated position more quickly, greatly improving installation efficiency. The coordinated operation of the two pulleys on the two slide rails not only ensures the stability of the ring network box during movement but also plays a role in initial positioning. This allows installers to more easily and accurately push the ring network box to the designed position, reducing the workload of adjusting position and correcting direction, and improving installation accuracy. Furthermore, pulley 15 can also slide on a horizontal plane, facilitating the handling and translation of the ring network box 11.

[0028] The bottom of the ring mesh box 11 has a heat dissipation vent. Because the pulley system is placed on the slide rail 13, there is a gap between the bottom of the ring mesh box 11 and the base plate 10, which helps dissipate heat from the ring mesh box 11 and maintains air exchange between the inside and outside of the ring mesh box 11. The heat dissipation process is combined with a fan or other water cooling function.

[0029] like Figures 3-4As shown, each track block 12 has two protruding plates 18 spaced apart on its outer side. A positioning element is slidably positioned between the two protruding plates 18 to stabilize the pulley system. The positioning element includes a slider 19, with screws 21 fixed to the front and rear of its upper end. A positioning sleeve 20 is fixed to the middle of the upper end of the slider 19, with a positioning bolt 17 passing through the positioning sleeve 20. The tail end of the positioning bolt 17 passes through the central shaft cylinder 16 and is limited by a nut. A nut 22 is threaded onto the screw 21, and the nut 22 is frictionally locked to the upper surface of the protruding plate 18.

[0030] After the ring network box 11 is positioned correctly, the slider 19 is placed between the two protruding plates 18, allowing it to slide freely within the gap between them. Once the slider 19 is in place, the positioning sleeve 20 is concentric with the central axis of the pulley system. The positioning bolt 17 is then passed through the positioning sleeve 20 and the central axis cylinder 16 of the pulley system. A nut is then screwed into the positioning bolt 17 for limiting movement, thus linking the positioning component and the pulley system. Finally, a nut 22 is screwed into the screw 21, and the nut 22 is frictionally locked against the upper surface of the protruding plate 18, preventing displacement of the slider 19 and ensuring the ring network box 11 remains stable. This fixing method is ingeniously designed, simple to operate, greatly reduces installation difficulty, and improves work efficiency. It also facilitates later maintenance, reducing maintenance costs and time.

[0031] The plane height of the convex plate 18 is higher than that of the slider 19. This facilitates a tight fit between the nut 22 and the surface of the convex plate 18 when tightening the nut 22. Additionally, the bottom surface of the nut 22 has anti-slip textures to enhance the tightening effect, or shims can be added to improve its stability.

[0032] like Figure 1 As shown, a side plate 23 is installed between the two track blocks 12. The side plate 23 has an L-shaped structure, and a reinforcing rib 24 is provided at the L-shaped corner of the side plate 23. After the pulley block is stabilized by the positioning component, the side plate 23 is finally added and attached to the front and rear sides of the ring network box 11. The side plate 23 is then bolted to the surface of the base plate 10, thereby further stabilizing the position of the ring network box 11 and improving its stability.

[0033] Alternatively, after stabilizing the pulley block with the positioning components, cement can be poured into the area below the ring network box 11. The cement-poured bottom can firmly fix and support the ring network box 11, ensuring its stability under various environmental conditions. This stability is crucial for the normal operation of the ring network box 11, preventing displacement or tilting caused by unstable foundations or external forces.
