[0026] Example 1

[0027] A low-voltage spanning frame, the low-voltage spanning frame includes a supporting leg 1, a first supporting rod 2, a second supporting rod 3 and a moving rod 4, a first cavity is formed on the first supporting rod 2, the second supporting rod 3 is arranged in the first cavity, a plurality of the supporting legs 1 are connected to the top end of the second supporting rod 3, the second supporting rod 3 is connected to a driving rod 5, a second cavity is formed inside the moving rod 4, one end of the second supporting rod 3 is passed through the second cavity, the moving rod 4 can move on the second supporting rod 3, a locking assembly 6 is connected to the moving rod 4, the locking assembly 6 is used to lock and fix the cable 100, and a lifting ring assembly 7 is connected to the locking assembly 6; a spanning pulley 8 is connected to the outer side of the top of the first supporting rod 2, a wire is wound around the spanning pulley 8, and the wire is connected to the driving rod 5, and a moving assembly 9 is connected to the bottom of the first supporting rod 2.

[0028] The number of the support legs 1 of the low-voltage crossing frame is three, and one end of the three support legs 1 is connected to the top of the second support rod 2. The second support rod 3 can move on the first support rod 2, and the moving rod 4 can move on the second support rod 3. The principle that the second support rod 3 can move on the first support rod 2 is as follows: the wire wound on the crossing pulley 8 is connected to the driving rod 5 on the second support rod 3 at one end, and then the crossing pulley 8 is rotated to pull the wire, and the wire then pulls the driving rod 5 to move the second support rod 3 upward relative to the first support rod 2. When the second support rod 3 moves to the desired position, the crossing pulley 8 is stopped from rotating, and the rotating rod of the crossing pulley 8 is fixed, so that the second support rod 3 rises to a certain height, so that the support height of the cable 100 on the low-voltage crossing frame can be adjusted. The principle by which the moving rod 4 can move on the second support rod 3 is as follows: Under normal circumstances, relying on the weight of the moving rod 4 itself, the inner top of the moving rod 4 is directly in contact with the top of the second support rod 3. When the moving rod 4 needs to be moved relative to the second support rod 3, the moving rod 4 is pulled upward through the lifting ring assembly 7, and the moving rod 4 is then moved upward relative to the second support rod 3.

The connecting column 742 passes through the through hole and is connected to the limit column 741. The lifting ring 744 is connected to the connecting column 743.

[0041] Example 8

[0042] Embodiment 8 provides a method for using the low-voltage spanning rack described above, which specifically includes the following steps:

[0043] S10. Move the low-voltage crossing frame to the wire and cable construction site through mobile components.

[0044] In a specific implementation scheme, the low-voltage spanning frame can be moved to a location where spanning wires are required by means of a moving assembly, thereby increasing the use flexibility of the low-voltage spanning frame.

[0045] S20. The plurality of support legs are spread out on the first support rod so that the low-voltage spanning frame is stably supported and fixed.

[0046] In a specific implementation scheme, when the low-voltage crossing frame needs to support cables at the wire and cable construction site, the support legs are unfolded from the first support rod to form a triangular frame, so that the support and span of the low-voltage crossing frame are guaranteed.

[0047] S30, connecting the lifting ring assembly to the equipment at the wire and cable construction site.

[0048] In a specific implementation scheme, when the supporting legs on the low-voltage crossing frame are opened, the lifting rings in the lifting ring assembly can be lifted to relevant equipment in the wire and cable construction site according to actual needs to further stabilize and fix the low-voltage crossing frame.

[0049] S40, then placing the cables on the clamping assembly, so that the low-voltage spanning rack provides appropriate support and passing space for the cables during the wiring process.

[0050] In a specific implementation scheme, after the low-voltage spanning frame is installed, the cables can be placed on the clamping assembly of the low-voltage spanning frame.

[0051] S50, connecting the wire wound on the crossing pulley to the driving rod, rotating the crossing pulley to shrink the wire onto the crossing pulley, pulling the driving rod through the wire, and then moving the second support rod upward, thereby achieving support height adjustment of the cables on the low-voltage crossing rack.

[0052] In a specific implementation scheme, for example, when the lifting ring assembly is not connected to the on-site equipment, the low-voltage crossing frame already supports cables. At this time, in order to ensure that the newly-mounted low-voltage line can be smoothly installed according to the predetermined line direction, the low-voltage cable of the newly-mounted frame will inevitably be adjusted in height during the wiring process. Then, the second support rod can be moved up or down by the crossing pulley, so that the low-voltage crossing frame can be flexibly adapted to the construction site.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
