Description

Technical Field

[0001] The invention relates to the technical field of cable bundling and positioning in transformer stations, and in particular to special bundling equipment for laying cables in cable trenches in transformer stations. Background Art

[0002] Transformer station: usually refers to the centralized installation location of power transformers, which are used to transform voltage to meet different distance and power requirements; cable trench is the place where power cables are installed to facilitate cable laying and maintenance; cable trench cables: refers to the wires and cables laid in the cable trench for transmitting current. These cables may include high-voltage, low-voltage, control cables and other types, which are selected according to the specific needs of the transformer station. High-voltage cable: used for high-voltage power transmission, such as 110kV, 220kV, etc., with high insulation performance requirements, and safety is also very important. Control cable: used to transmit control signals or protection signals inside the transformer, parallel to the main cable;

[0003] After the cables are laid in the cable trench, they need to be bundled together with the cable rack. For the suspended part of the cables, multiple cables also need to be bundled together. The current bundling methods are mainly as follows: wrap the cable tie around the cable, starting from the outside of the cable, to ensure that the cable tie does not press on the insulation layer of the cable; follow the "cross bundling" principle, that is, one cable tie passes from the top of the cable, and the next cable tie passes from the bottom. This can better disperse the pressure and avoid single-point force.

[0004] The current manual bundling method is time-consuming and inefficient. At the same time, changing the cable posture requires applying a large force, which is difficult to apply manually. The cable tie can only play a simple restraining effect and cannot correct the cable posture. Summary of the Invention

[0041] 8. The cable posture trimming component can pre-adjust the cables in front of the cable rack to a horizontal state before the bundling parts are positioned, without shifting up and down or left and right. In this way, the downward pressure resistance of the downward pressure component is smaller. At the same time, the cable positioning angle is more appropriate, and the distortion of the cable when it is pressed down is minimized, ensuring the smoothness of the entire extension of the cable, higher cable transmission stability and longer service life.

The binding pieces 7 of adjacent bent clamps can be clamped together to connect the suspended parts of multiple cables.

[0069] In the above scheme,

[0070] 1. The new cable rack makes it easier to install the bundled parts and also facilitates the docking and assembly of the rack, so that the dedicated bundled equipment can be quickly docked and switched.

[0071] 2. The design of the strapping has the following effects:

When fixing the suspended part of the cable, the bundle can be bent and deformed to support the cable from the bottom to achieve locking and positioning;

[0074] 2.3. Multiple bundles can be assembled. When fixing the suspended part of the cable, after a single bundle is fixed to the cable, the adjacent bundles can be connected as one, thereby connecting multiple cables in the suspended part as one. In this way, it is not limited to the number of cables that need to be positioned, and has a wider range of applications;

[0075] 2.4. Whether it is the bundle installed on the cable rack or the bundle fixed on the suspended part, it can be removed, which is convenient for subsequent disassembly maintenance or cable installation.

[0076] 3. The support assembly is the main supporting structure of the entire equipment. Other components can be deployed when in use and can be stored above and below the support assembly when not in use. In this way, the equipment is transformed into a rectangular structure, which takes up little space and is easy for workers to carry by handles.

[0077] 4. The design of the bracket can ensure the stability of the supporting assembly during operation, and can also serve as a moving track for the supporting assembly, making it easier to press down the assembly to bundle the suspended part of the cable;

[0078] 5. The design of the pressing component can automatically press down the bundle, so that the bundle is automatically stuck into the cable rack or clamped on the suspended part of the cable, meeting the positioning requirements of large-size cables;

[0079] 6. The adjustment component can change the position of the pressing component, so that the pressing component can move up and down, forward and backward, and the pressing component can complete actions in different states.

[0080] 7. The loading component can be moved horizontally to automatically add the bundled parts to the pressing component. The pressing component can automatically take out and add materials without manual feeding.

[0081] 8. The cable posture trimming component can pre-adjust the cables in front of the cable rack to a horizontal state before the bundling parts are positioned, without shifting up and down or left and right. In this way, the downward pressure resistance of the downward pressure component is smaller. At the same time, the cable positioning angle is more appropriate, and the distortion of the cable when it is pressed down is minimized, ensuring the smoothness of the entire extension of the cable, higher cable transmission stability and longer service life.

[0082] In this embodiment, the binding member 7 includes a U-shaped splint 71, and the two protruding ends of the U-shaped splint 71 are vertically provided with protruding teeth 72, and the side walls of the protruding teeth 72 are provided with a first locking groove 721.

[0084] The U-shaped clamp can position the cable from three sides. The convex teeth are designed to engage with the cable rack and can bend when the cable is suspended. The bent convex teeth support the cable from the bottom.

[0085] The design of connecting plates and connecting sleeves can realize the assembly positioning between adjacent bundles, and facilitate the positioning between multiple bundles;

[0086] When the connecting plate is engaged with the connecting sleeve, the third spring rod can drive the locking plate to reset, and the locking plate can be inserted into the first locking groove, thereby achieving lateral extrusion positioning and vertical stopping to prevent the connecting plate from being separated from the connecting sleeve.

A back rod 811 for stopping the strapping piece 7 is provided on the back of the assembly base 81. The clamping plate 83 is used to clamp and position the bundling piece 7 from both sides; in the third state, the first driving rod 33 drives the pressing assembly 8 to descend to insert the bundling piece 7 into the reserved groove 111 of the bracket 11. After the insertion is completed, the second driving rod 34 drives the pressing assembly 8 to retreat; in the fifth state, the first driving rod 33 drives the pressing assembly 8 to descend to clamp the bundling piece 7 in the suspended part of the cable, and the bending assembly 84 bends the convex plate of the bundling piece 7 so that the convex plate stops at the bottom of the cable; after the insertion is completed, the second driving rod 34 drives the pressing assembly 8 to retreat.
