[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, a temporary power supply line erection mechanism comprises a bottom plate 10 for being arranged on a cement base, a column 20 is arranged in the middle of the bottom plate 10, and a laying assembly 30 for laying cables is arranged at the upper end of the column 20;

[0032] The laying assembly 30 includes a sliding sleeve 31 slidably mounted on the column 20, a mounting plate 32 and a vertical pole 33 are provided on the sliding sleeve 31, a fixed pulley 34 is rotatably provided on the vertical pole 33, a hook 35 is provided on the mounting plate 32, and also includes a cross bar 361 hung on the hook 35 through a hanging ear 36, insulators 362 are provided at both ends of the cross bar 361, a cable fixing ring 38 is provided at the lower end of the insulator 362, a pulling rope 37 is wound around the fixed pulley 34, a section of the pulling rope 37 is fixedly provided on the mounting plate 32, and the other end of the pulling rope 37 is used to drive the cross bar 361 and the sliding sleeve 31 to slide on the column 20 after moving.

[0033] In this embodiment, the base plate 10 is fixed on a cement base to ensure that it is horizontal and stable. Then, the column 20 is installed in the middle of the base plate 10, and the column 20 serves as the supporting structure of the entire erection mechanism. The sliding sleeve 31 is sleeved on the column 20, and the cross bar 361 is hung on the hook 35 on the mounting plate 32. The insulators 362 and the cable fixing ring 38 at both ends of the cross bar 361 are used to fix the cable. The cable is passed through the cable fixing ring 38 and fixed, and the cross bar 361 and the sliding sleeve 31 are pulled up and down on the column 20 by the pulling rope 37 on the fixed pulley 34 to adjust the laying height of the cable to reach a suitable erection position. Through the design of the sliding sleeve 31 and the pulling rope 37, the laying height of the cable can be quickly adjusted, which greatly shortens the erection time of the temporary power supply line and improves the construction efficiency. The insulators 362 and the cable fixing ring 38 at both ends of the cross bar 361 effectively protect the cable, prevent the cable from being damaged during the erection process, and ensure the safety of the operator. The sliding sleeve 31 can slide freely on the column 20, and the cable height can be flexibly adjusted on site according to needs to adapt to different temporary power supply scenarios. The entire erection mechanism has a simple structure and a small number of parts, which is convenient for on-site installation and maintenance, reduces the cost of use, and solves the problem that the installation and removal process of the temporary cable erection mechanism in the prior art is complicated and time-consuming, and is not easy to flexibly adjust.

[0034] like Figure 1 and Figure 4 As shown, as a further technical solution, a winding mechanism 40 is arranged on the base plate 10, and the winding mechanism 40 includes a mounting seat 41 arranged on the base plate 10, and the reel 42 is rotatably arranged on the mounting seat 41, and the other end of the pulling rope 37 is wound around the reel 42. After the reel 42 rotates, it is used to drive the sliding sleeve 31 to slide on the column 20, and also includes a first driving unit 43 arranged on the mounting seat 41, and the first driving unit 43 is used to drive the reel 42 to rotate.

[0035] In this embodiment, by setting a reeling mechanism 40 on the base plate 10, the automatic reeling and releasing of the pulling rope 37 is realized, so as to more efficiently control the sliding of the sliding sleeve 31 on the column 20. The reeling mechanism 40 includes a mounting seat 41, a reel 42 and a first driving unit 43. The mounting seat 41 is fixed on the base plate 10, and the reel 42 is rotatably arranged on the mounting seat 41 through a bearing, and the other end of the pulling rope 37 is wound on the reel 42. When the reel 42 rotates, the pulling rope 37 is rolled up or released, thereby driving the sliding sleeve 31 to slide up and down on the column 20, so as to realize the rapid adjustment of the cable laying height. The first driving unit 43 (such as a motor) is installed on the mounting seat 41, connected to the reel 42, and is used to drive the reel 42 to rotate forward and reverse. The operator can easily realize the precise adjustment of the cable height by controlling the start and stop of the first driving unit 43, further improving the construction efficiency and the convenience of operation.

[0036] like Figure 4 and Figure 5 As shown, as a further technical solution, a stabilizing frame 44 is provided at the upper end of the mounting seat 41 , and the stabilizing frame 44 is sleeved on the outside of the pulling rope 37 .

[0037] In this embodiment, in order to further improve the stability of the pulling rope 37 during operation and prevent it from loosening or deflecting during winding and releasing, the winding mechanism 40 is optimized. Specifically, a stabilizing frame 44 is added to the upper end of the mounting seat 41. The frame is U-shaped or rectangular and is sleeved on the outside of the pulling rope 37. The stabilizing frame 44 is made of high-strength aluminum alloy material, has good support and guiding functions, and reduces the overall weight without affecting the flexibility of the winding mechanism 40. Through the constraint of the stabilizing frame 44, the pulling rope 37 always maintains linear motion during the winding and releasing process, avoiding the jamming of the sliding sleeve 31 caused by the shaking or twisting of the rope. This improvement not only improves the reliability of the line erection process, but also extends the service life of the pulling rope 37 and the winding mechanism 40, further improving the performance and stability of the temporary power supply line erection mechanism.

[0038] like Figure 1 and Figure 4 As shown, as a further technical solution, two support plates 50 are provided on the mounting plate 32 , and the support plates 50 are respectively located at the upper and lower ends of the cross bar 361 .

[0039] In this embodiment, in order to further enhance the stability of the crossbar 361 and ensure its firmness on the hook 35, the laying component 30 is optimized. Specifically, two support plates 50 are set on the mounting plate 32, and the two support plates 50 are respectively located at the upper and lower ends of the crossbar 361. The support plate 50 is made of high-strength steel and is welded and fixed to the mounting plate 32 to form a stable support structure. When the crossbar 361 is hung on the hook 35 through the hanging ear 36, the support plate 50 at the upper end can limit the crossbar 361 to prevent it from shaking in the horizontal direction; the support plate 50 at the lower end provides additional support for the crossbar 361 to ensure that it remains stable when bearing the weight of the cable. This design not only improves the carrying capacity of the crossbar 361, but also effectively avoids the risk of loosening or falling off of the cable due to the shaking of the crossbar 361, further improving the safety and reliability of the erection of temporary power supply lines.

[0040] like Figure 1 and Figure 4 As shown, as a further technical solution, the base plate 10 has a plurality of mounting holes 11 , and the base plate 10 is used to be fixed on a cement base by passing bolts through the mounting holes 11 .

[0041] In this embodiment, the fixing method of the base plate 10 is further optimized. Specifically, a plurality of mounting holes 11 are provided on the base plate 10, and these mounting holes 11 are evenly distributed around the base plate 10, and are used to fix it to the cement base by bolts. The diameter of the mounting hole 11 matches the bolt specification to ensure the tightness and stability of the connection. In the actual installation process, the user can select the mounting hole 11 in a suitable position for bolt fixing according to the size and installation requirements of the cement base. This design not only improves the installation flexibility of the base plate 10, but also enhances the wind resistance and earthquake resistance of the entire erection mechanism, so that it can better adapt to the complex outdoor working environment and ensure the stable operation of the temporary power supply line.

[0042] like Figure 1 and Figure 4 As shown, as a further technical solution, a slide groove 21 is provided on one side of the surface of the column 20 , and a protrusion 311 is provided on one side of the sliding sleeve 31 , and the protrusion 311 is slidably disposed in the slide groove 21 .

[0043] In this embodiment, a sliding groove 21 is provided on one side of the surface of the column 20, and a protrusion 311 is provided on one side of the sliding sleeve 31, and the protrusion 311 is slidably arranged in the sliding groove 21. This design enables the sliding sleeve 31 to slide up and down along the column 20 more stably through the cooperation between the sliding groove 21 and the protrusion 311, thereby avoiding shaking or deviation during the sliding process.

[0044] like Figure 1 and Figure 4 As shown, as a further technical solution, a limiting block 22 is provided at the top end of the column 20 in the slide groove 21 .

[0045] In this embodiment, in order to further improve the sliding stability and safety of the sliding sleeve 31 on the column 20, the structure of the column 20 and the sliding sleeve 31 is optimized. Specifically, a limit block 22 is set in the slide groove 21 at the top of the column 20. The limit block 22 is made of high-strength metal material and is fixed at the end of the slide groove 21. It is used to limit the upward movement of the sliding sleeve 31 to prevent it from detaching from the column 20 due to excessive sliding. When the protrusion 311 of the sliding sleeve 31 approaches the limit block 22, the limit block 22 will prevent it from continuing to move upward, thereby ensuring that the sliding sleeve 31 always slides within a safe range. This design not only effectively avoids the risk of the sliding sleeve 31 falling off due to operational errors or external forces, but also improves the reliability and service life of the entire erection mechanism, providing a stronger guarantee for the stable operation of the temporary power supply line.

[0046] like Figure 3As shown, as a further technical solution, the cable fixing ring 38 includes an upper ring 381 and a lower ring 382 , and the upper ring 381 and the lower ring 382 are set by adjusting bolts 383 .

[0047] In this embodiment, in order to further improve the effect and flexibility of cable fixing, the cable fixing ring 38 at the top of the column 20 is optimized. Specifically, the cable fixing ring 38 is composed of an upper ring 381 and a lower ring 382, ​​and the two are connected by an adjusting bolt 383. The upper ring 381 and the lower ring 382 are both semicircular structures, made of high-strength insulating materials, and have good electrical insulation properties and mechanical strength. When installing the cable, place the cable in the lower ring 382, ​​and then tighten the adjusting bolt 383 to make the upper ring 381 fit tightly with the lower ring 382, ​​so as to firmly fix the cable. This adjustable design can not only adapt to cables of different diameters, but also achieve rapid adjustment and fixation during the cable installation process, ensuring that the cable is stable and reliable during the installation process, and effectively avoiding the risk of power supply interruption caused by loose cables.

[0048] like Figure 1 , Figure 4 and Figure 5 As shown, as a further technical solution, the fixed pulley 34 is detachably arranged on the vertical rod 33, and the mounting plate 32 is fixedly arranged on the sliding sleeve 31 by bolts.

[0049] In this embodiment, in order to improve the versatility and maintenance convenience of the equipment, the connection method of the fixed pulley 34 and the mounting plate 32 on the vertical pole 33 is optimized. Specifically, the fixed pulley 34 is installed on the vertical pole 33 in a detachable manner, and is quickly disassembled and assembled through a threaded connection or a snap-on structure, which is convenient for replacing or repairing the fixed pulley 34 when necessary, and can also adapt to pulling ropes 37 of different diameters. In addition, the mounting plate 32 is fixed to the sliding sleeve 31 by bolts. This connection method not only ensures a firm connection between the mounting plate 32 and the sliding sleeve 31, but also facilitates adjustment or replacement of the mounting plate 32 when necessary. The design of the detachable fixed pulley 34 and the bolt-fixed mounting plate 32 makes the entire erection mechanism more flexible during maintenance and upgrading, reduces the maintenance cost of the equipment, and improves its applicability and service life in different scenarios.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
