A first arc-shaped clamping plate 4 is fixedly provided inside the left half frame 2, and the first arc-shaped clamping plate 4 is fixedly connected to the web of the left half frame 2 through a connecting rod 17. A second arc-shaped clamping plate 5 is slidably provided inside the right half frame 3, and the second arc-shaped clamping plate 5 can move in a direction away from or close to the first arc-shaped clamping plate 4, so as to be clamped or loosened on the wire rod 1. The inner sides of the first arc-shaped clamping plate 4 and the second arc-shaped clamping plate 5 can be detachably connected with an arc-shaped thickened plate 6, and a first locking component for locking and fixing the relative positions of the two arc-shaped thickened plates 6 is provided between the two arc-shaped thickened plates 6.

A clamping assembly for clamping the relative position of the force-applying end of the pulley 8 assembly is also arranged on the outer side of the column 7.

[0029] like Figure 7-9As shown, a mounting plate is integrally formed on the outer side of the top of the arc-shaped thickened plate 6. In fact, a convex column can be provided on the lower end surface of the mounting plate, and a blind hole matching the convex column is provided on the first arc-shaped clamping plate 4 and the second arc-shaped clamping plate 5, so that the arc-shaped thickened plate 6 can be quickly and conveniently installed or removed from the first arc-shaped clamping plate 4 / the second arc-shaped clamping plate 5; in this embodiment, a mounting bolt 19 is provided between the mounting plate and the first arc-shaped clamping plate 4 / the second arc-shaped clamping plate 5, a first threaded hole 18 is provided on the top of the first arc-shaped clamping plate 4 / the second arc-shaped clamping plate 5, and a second threaded hole is provided on the mounting plate, and one end of the mounting bolt 19 passes through the second threaded hole and the first threaded hole 18 in sequence, so as to lock and fix the arc-shaped thickened plate 6 and the first mounting plate / the second mounting plate. With such a structural design, when dealing with wire rods 1 of different diameters, arc-shaped thickened plates 6 of different thicknesses can be installed on the first arc-shaped clamping plate 4 / the second arc-shaped clamping plate 5 to achieve the purpose of firmly clamping the wire rod 1, thereby enhancing the adaptability of the device, having a simple structure, a reliable connection, and easy replacement.

[0030] In the above embodiment, the first arc-shaped clamping plate 4 and the second arc-shaped clamping plate 5 are both two-thirds semicircular arc-shaped plates, and the arc-shaped thickened plate 6 is a semicircular arc-shaped plate.

When the first arc-shaped clamping plate 4 and the second arc-shaped clamping plate 5 drive the arc-shaped thickened plate 6 to be clamped and fixed on the wire rod 1, the support ears 20 of the two arc-shaped thickened plates 6 just fit together. At this time, one end of the first bolt 21 passes through the two support ears 20 and cooperates with the first nut 22, so that the arc-shaped thickened plate 6 is firmly clamped and fixed on the wire rod 1.

[0032] like Figure 7-9 As shown, an adjusting member 14 for adjusting the sliding position of the second arc-shaped clamping plate 5 is provided between the outer side of the second arc-shaped clamping plate 5 and the web of the right half frame 3. The adjusting member 14 is a bolt. A third threaded hole for the adjusting member 14 to pass through is provided in the middle of the web of the right half frame 3. The adjusting member 14 is threadedly connected to the right half frame 3. A through hole for the adjusting member 14 to be inserted is provided on the outer side of the second arc-shaped clamping plate 5. The adjusting member 14 passes through the first threaded hole 18 and the through hole in sequence and is rotatably connected to the second arc-shaped clamping plate 5 through a bearing.

A sliding groove 15 is provided on the wing plate of the right half frame 3 along the axial direction of the adjusting member 14. One end of the limiting block 16 is fixedly connected to the outer side of the second arc-shaped clamping plate 5, and the other end is located in the sliding groove 15 and slides with the sliding groove 15.

[0033] In this embodiment, since there is a gap between the second arc-shaped clamping plate 5 and the two wing plates of the right half frame 3, in order to prevent the second arc-shaped clamping plate 5 from rotating with the adjusting member 14, a stopper 16 and a slide slot 15 are provided. By rotating the adjusting member 14, the second arc-shaped clamping plate 5 can be driven to move along the axial direction of the adjusting member 14, so as to be close to or away from the first arc-shaped clamping plate 4.

[0034] like Figure 1-4 As shown, a support plate 29 is fixedly provided on the outer surface of the web of the left half frame 2, a column 7 is fixedly installed on the top of the support plate 29, a mounting seat 13 is fixedly provided on the bottom of the outer wall of the column 7, a wire groove 24 is provided on the mounting seat 13, a pulley assembly comprises a fixed pulley 8, a rope 10 and a movable pulley 9, the fixed pulley 8 is fixedly installed on the top of the column 7, the movable pulley 9 is located below the fixed pulley 8, and the diameter of the movable pulley 9 is the wing plate of the fixed pulley 8, one end of the rope 10 is fixed to the bottom of the fixed pulley 8, and the other end passes through the movable pulley 9 and the fixed pulley 8 in sequence and is inserted into the wire groove 24. A tool box 11 is fixed at the bottom of the movable pulley 9, a slip ring 12 is fixedly provided on the side wall of the tool box 11, the slip ring 12 is slidably sleeved on the column 7, the clamping assembly is located on the mounting seat 13, and the slip ring 12 can guide the tool box 11. Through this structure, the force of pulling the rope 10 is equal to half of the weight of the tool box 11, which can drive the movable pulley 9 to rise and fall. The structure is reasonable and labor-saving.

[0035] like Figure 4-5 As shown, the clamping assembly includes a nut seat 23, which is fixedly connected to the side wall of the fixing seat. The nut seat 23 is internally threaded with a clamping bolt 25, which passes through the nut seat 23 and the side wall of the mounting seat 13 and extends into the wire groove 24. By turning the clamping bolt 25, the clamping bolt 25 can be used to tighten or loosen the rope 10 at the same time, so that the tool box 11 can be raised and lowered at any time, which is convenient for the personnel below to pass tools to the operators above at a later time, thereby meeting the use requirements.

[0036] like Figure 2-3 As shown, a second locking member is arranged between the left half frame 2 and the right half frame 3, and the second locking member includes a second bolt 27 and a second nut 28. Mounting blocks 26 are fixedly arranged on the left half frame and the right half frame 3, respectively. The mounting blocks 26 are provided with through holes for the second bolts 27 to pass through. One end of the second bolt 27 passes through the two mounting blocks 26 and cooperates with the second nut 28 to lock and fix the left half frame 2 and the right half frame 3. The structure is simple and the connection is firm, so that the installation of the device is very stable. After the installation is successful, it will be difficult for non-human factors to cause the overall equipment to loosen.

[0037] The working principle of this embodiment is as follows:

[0038] For the wire rods 1 of different diameters, select the arc-shaped thickened plates 6 of corresponding sizes, and install the arc-shaped thickened plates 6 on the first arc-shaped clamping plate 4 / the second arc-shaped clamping plate 5; fix the left half frame 2 and the right half frame 3 on the wire rod 1. The specific fixing process is to open the right half frame 3, take the appropriate position to sleeve the left and right half frames 3 on the bottom of the wire rod 1, buckle the right half frame 3, and lock and fix the left and right half frames 3 by the second bolt 27 and the second nut 28; turn the adjustment member 14 to make the second arc-shaped clamping plate 5 and its corresponding arc-shaped thickened plates 6 close to the first arc-shaped clamping plate 4 until the two arc-shaped thickened plates 6 are against each other, and the two arc-shaped thickened plates 6 are locked and fixed by the first bolt 21 and the first bolt 21, so as to complete the fixing of the left half frame 2 and the right half frame 3. At this time, the maintenance tools can be placed in the tool box 11, and then the tool box 11 can be raised or lowered to facilitate the operation of the maintenance personnel, and also to facilitate the transfer of tools from the lower personnel to the upper maintenance personnel in the later stage.

[0039] When raising the tool box 11, first loosen the clamping bolt 25, then pull the rope 10, the rope 10 rotates along the fixed pulley 8 and the movable pulley 9 and pulls up the tool box 11. The pulling force at this time is half of the gravity of the tool box 11, which makes lifting convenient and labor-saving. After reaching the target height, tighten the clamping bolt 25 to fix the tool box 11. When the tool box 11 needs to be lowered, the above operation can be reversed.
