[0002] The cable pulley is needed when the power transmission project is performing the line operation. The cable pulley can provide a good support effect for the power supply cable and avoid friction damage to the power supply cable during the installation. The cable pulley on the market is usually composed of a connecting frame and a pulley. The connecting frame can drive the pulley to be fixed in a suitable position, which can provide a good line installation effect for the power supply cable.

[0003] However, the connecting frame of the cable pulley on the market is usually a U-shaped structure. When the power supply cable is connected to the cable pulley, the staff needs to pass the power supply cable through the connecting frame, which will cause great inconvenience in connecting the power supply cable to the cable pulley. Since the connecting frame of the cable pulley is a U-shaped structure, the pulley and the connecting frame can form a rectangular structure. After the cable pulley pulls the power supply cable, it is not convenient for the staff to separate the pulled power supply cable and the cable pulley, which will cause great inconvenience in disassembling the cable pulley. At the same time, the connecting frame on the existing cable pulley usually needs to be fixed to the external equipment with bolts. When used on some stone walls, there will be gaps between the stones in the stone wall. These gaps are not convenient for installing bolts, which will make it inconvenient for the connecting frame of the cable pulley to be fixed to the stone wall. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-Figure 6The transmission line engineering cable construction pulley shown in the figure comprises a roller 6 and a support rod 4 abutting against one side of the roller 6, a plug-in column 14 is inserted into the roller 6, one end of the plug-in column 14 is provided with a first threaded portion 26, and the other end of the plug-in column 14 is provided with a second threaded portion 27, and one end of the plug-in column 14 with the second threaded portion 27 penetrates the support rod 4, and the plug-in column 14 is connected to a second connecting bolt 16 through the second threaded portion 27, and one end of the plug-in column 14 with the first threaded portion 26 is provided. The end is sleeved with a limit plate 20, the plug column 14 is connected to the first connecting bolt 15 through the first threaded portion 26, the limit plate 20 is fixedly connected to the connecting rod 5, the connecting rod 5 is fixedly connected to the bending portion 18, the upper end of the support rod 4 is rotatably connected to the rotating tube 9, one side of the rotating tube 9 is fixedly connected to the pull rod 8, the other side of the rotating tube 9 is fixedly connected to the upper plug plate 1, the end of the pull rod 8 away from the rotating tube 9 is fixedly connected to the pressing rod 10, and the pressing rod 10 is in contact with the bending portion 18;

[0026] The roller 6 can be connected to a power supply cable. When the upper plug-in piece 1 is inserted into the gap of the stone, the bent portion 18 can be connected to the pressure rod 10. At this time, the connecting rod 5 can shield the power supply cable to prevent the power supply cable from being separated from the roller 6.

[0027] A sliding groove 12 is provided on the side of the support rod 4 facing away from the roller 6, and the support rod 4 is slidably connected to the lower plug-in piece 3 through the sliding groove 12, and an extrusion spring 2 is connected between the lower plug-in piece 3 and the rough portion 7, and the top surface of the upper plug-in piece 1 and the bottom surface of the lower plug-in piece 3 are both provided with a rough portion 7;

[0028] The lower plug-in piece 3 can slide on the support rod 4 through the sliding groove 12. At this time, the distance between the lower plug-in piece 3 and the upper plug-in piece 1 can be adjusted, so that the upper plug-in piece 1 and the lower plug-in piece 3 can be plugged into the gaps of stones of different sizes.

[0029] Bolt holes 13 are provided on both sides of the sliding groove 12 on the support rod 4, and a fixing bolt 11 is passed through the lower plug-in piece 3. The fixing bolt 11 passes through the lower plug-in piece 3 and extends to the inside of the bolt hole 13;

[0030] When the fixing bolt 11 passes through the lower plug-in plate 3 and extends into the bolt hole 13, the spacing between the lower plug-in plate 3 and the upper plug-in plate 1 can be adjusted, so that the upper plug-in plate 1 and the lower plug-in plate 3 can be plugged into the gaps of stones of different sizes.

[0031] The plug-in column 14 is sleeved with a plug-in tube 24, which is plugged into the penetration portion between the limiting plate 20 and the plug-in column 14. The end of the plug-in tube 24 away from the limiting plate 20 is fixedly connected with an abutment ring 22, which is threadedly connected to the plug-in column 14 through a first threaded portion 26;

[0032] When the plug-in tube 24 is plugged into the penetration portion between the limiting piece 20 and the plug-in column 14, the limiting piece 20 can rotate on the plug-in tube 24, and at this time, it is convenient for the staff to hang the bent portion 18 on the pressure rod 10;

[0033] The bending portion 18 is an arc-shaped structure. When the bending portion 18 is hung on the pressing rod 10 , the closer the pressing rod 10 is to the connecting rod 5 , the larger the angle between the upper plug-in piece 1 and the lower plug-in piece 3 .

[0034] The side of the abutment ring 22 facing away from the plug-in tube 24 is fixedly connected with the abutment tube 23, the side of the abutment tube 23 facing away from the abutment ring 22 is abutted with the sleeve ring 25, the side of the sleeve ring 25 facing away from the abutment tube 23 is abutted with the first connecting bolt 15, and the abutment tube 23 and the sleeve ring 25 are both sleeved on the plug-in column 14;

[0035] Since the abutment ring 22 is threadedly connected to the plug-in column 14 through the first threaded portion 26, when the abutment ring 22 rotates to the end of the first threaded portion 26, the pressure groove of the first threaded portion 26 will abut against the abutment ring 22. At this time, the abutment ring 22 cannot continue to approach the limiting plate 20. At the same time, the first connecting bolt 15 is connected to the first threaded portion 26. The first connecting bolt 15 can cooperate with the abutment tube 23 to squeeze the sleeve ring 25, so as to prevent the sleeve ring 25 from rotating on the plug-in column 14.

[0036] The limiting piece 20 is provided with plug holes 19 at equal intervals with the axis of the plug column 14 as the center. A rotating handle 21 is fixedly connected to the limiting piece 20. The angle between the rotating handle 21 and the connecting rod 5 is an obtuse angle. A connecting pipe 17 is distributed on the side of the sleeve ring 25 close to the limiting piece 20. The connecting pipe 17 is threadedly connected to the sleeve ring 25 through a connecting thread 30. One end of the connecting pipe 17 close to the abutting ring 22 passes through the limiting column 28. The end of the limiting column 28 close to the abutting ring 22 is provided with a rounded portion 32. The limiting column 28 is plugged into the plug hole 19 through the rounded portion 32. The end of the limiting column 28 away from the abutting ring 22 is fixedly connected with a sliding piece 29. A limiting spring 31 is fixedly connected between the sliding piece 29 and the connecting pipe 17.

[0037] When the staff's hand drives the limit plate 20 to rotate by turning the handle 21, the limit plate 20 can drive the use position of the bending portion 18 to be adjusted. When the bending portion 18 is hung on the pressure rod 10, the angle between the upper plug-in plate 1 and the lower plug-in plate 3 can be adjusted. Since the limit column 28 can be inserted into the interior of the plug-in hole 19, the use position of the bending portion 18 can also be limited.

[0038] Working principle: When the cable pulley is actually used, the staff separates the bending portion 18 from the pressing rod 10 by turning the handle 21. The state of the bending portion 18 and the pressing rod 10 being separated can be referred to the attached figure of the specification. Figure 2When the bending portion 18 is separated from the pressure rod 10, the repulsive force generated by the extrusion spring 2 can drive the end of the upper plug-in piece 1 to abut against the end of the lower plug-in piece 3, which can facilitate the staff to insert the upper plug-in piece 1 and the lower plug-in piece 3 into the gap of the stone wall. At the same time, the staff can also separate the fixing bolt 11 from the bolt hole 13, which can facilitate the lower plug-in piece 3 to slide on the support rod 4 through the sliding groove 12. When the fixing bolt 11 penetrates the lower plug-in piece 3 and is connected with the bolt hole 13, the use position of the lower plug-in piece 3 can be fixed. Then the staff plugs the power supply cable into the roller 6, and then the staff hangs the bending portion 18 and the pressure rod 10 by turning the handle 21. Since the limiting column 28 can be inserted into the inside of the plug hole 19, the use position of the bending portion 18 can also be limited at this time, which can prevent the bending portion 18 from being separated from the pressure rod 10. At the same time, the connecting rod 5 can also block the power supply cable, which can prevent the power supply cable from being separated from the roller 6.
