Abstract
Description
Technical Field
[0001] This utility model relates to the field of bolt fastening technology, specifically a device for fastening anchor bolts of power transmission line towers. Background Technology
[0002] In the installation and maintenance of power transmission line towers, anchor bolts are key components connecting the tower and the base, and the efficiency and reliability of their tightening and dismantling operations directly affect the quality of the project.
[0003] Currently, traditional bolt tightening tools are mostly fixed-size sockets or wrenches. Because the diameter and pitch of anchor bolts for transmission towers vary, workers need to carry multiple types of tools to fit different bolt sizes. This not only increases the burden of carrying tools but also frequently causes work interruptions due to tool changes, reducing construction efficiency. Therefore, we propose a bolt tightening device for transmission line towers. Utility Model Content
[0004] The purpose of this utility model is to provide a fastening device for anchor bolts of power transmission line towers, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fastening device for anchor bolts of transmission line towers, comprising a base, an anchor bolt body being provided at the upper end of the base, a sleeve being provided on the outer side of the anchor bolt body, a handle being provided on one side of the upper end of the sleeve, an adjustment component being provided on the outer side of the sleeve for adaptive adjustment according to the size of the anchor bolt, and a limiting component being provided at the upper end of the sleeve for limiting the handle.
[0006] Optionally, the adjusting assembly includes an adjusting ring disposed on the outside of the sleeve, with smooth rods welded to both sides of the lower end of the adjusting ring, wedge blocks movably mounted on both sides of the lower end of the sleeve, a screw rod rotatably mounted in the middle of the adjusting ring via a bearing, and a threaded groove formed in the middle of the upper end of the sleeve.
[0007] Optionally, a hinge seat is fixedly installed at the upper end of the sleeve, and the handle is rotatably connected to the sleeve through the hinge seat.
[0008] Optionally, the lower end of the smooth rod is in contact with the inclined surface of the wedge block, and the smooth rod is symmetrically arranged.
[0009] Optionally, the limiting component includes a limiting frame disposed above the sleeve, the limiting frame being movably connected to the sleeve, a lead screw sleeve being fixedly installed at the upper end of the limiting frame, a lead screw being welded to the upper end of the screw, and the lead screw being threadedly connected to the lead screw sleeve.
[0010] Optionally, the screw is sized to match the thread groove, and the screw and the thread groove are helically connected.
[0011] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0012] The technical solution of this application, through the setting of a base, anchor bolt body, sleeve, handle, adjusting ring, screw, limiting frame, and lead screw, allows the smooth rod to push the wedge block, so that the wedge block abuts against the outside of the anchor bolt, thereby achieving the effect of adaptive adjustment according to the size of the anchor bolt. This facilitates the disassembly of anchor bolts of different sizes by the workers, further improving the efficiency of tightening or disassembling anchor bolts. At the same time, during the rotation of the screw, the left side of the limiting frame can be inserted into the handle, thereby achieving the effect of limiting the handle. After the anchor bolt is tightened, the limiting frame can be controlled to move upward, separating the limiting frame from the handle, thereby facilitating the rotation of the handle and reducing the space occupied by the sleeve and handle.

[0017] Please see Figure 1-2 This utility model provides a technical solution: a fastening device for anchor bolts of transmission line towers, including a base 1, an anchor bolt body 11 is provided at the upper end of the base 1, a sleeve 12 is provided on the outer side of the anchor bolt body 11, a handle 13 is provided on one side of the upper end of the sleeve 12, an adjustment component for adaptive adjustment according to the size of the anchor bolt is provided on the outer side of the sleeve 12, and a limiting component for limiting the handle 13 is provided at the upper end of the sleeve 12.
[0018] In this embodiment, when disassembling the anchor bolt, the sleeve 12 is first placed on the outside of the anchor bolt body 11, and then the adjustment component is controlled to move so that the adjustment component can be adjusted according to the size of the anchor bolt, thereby facilitating the disassembly of anchor bolts of different sizes by the workers and further improving the efficiency of tightening or disassembling the anchor bolt. At the same time, during the movement of the adjustment component, the limiting component will be driven to move along with it, so that the limiting component limits the handle 13, thereby facilitating the rotation of the sleeve 12.
[0019] In this technical solution, the adjustment assembly includes an adjustment ring 2 disposed on the outside of the sleeve 12. Smooth rods 21 are welded to both sides of the lower end of the adjustment ring 2. Wedge blocks 22 are movably installed on both sides of the lower end of the sleeve 12. A screw 23 is rotatably installed in the middle of the adjustment ring 2 via a bearing. A threaded groove 24 is opened in the middle of the upper end of the sleeve 12.
[0020] In this embodiment, during adjustment, the screw 23 is rotated, and the screw 23 moves the adjusting ring 2 downward along the threaded groove 24. The adjusting ring 2 moves the smooth rod 21 downward, causing the smooth rod 21 to push the wedge block 22, so that the wedge block 22 abuts against the outside of the anchor bolt. This achieves the effect of adaptive adjustment according to the size of the anchor bolt, which facilitates the disassembly of anchor bolts of different sizes by the staff and further improves the efficiency of tightening or disassembling anchor bolts.
[0021] In this technical solution, a hinge seat 14 is fixedly installed at the upper end of the sleeve 12, and the handle 13 is rotatably connected to the sleeve 12 through the hinge seat 14.
[0022] In this embodiment, the hinge seat 14 facilitates the rotation of the handle 13.
[0023] In this technical solution, the lower end of the smooth rod 21 is in contact with the inclined surface of the wedge block 22, and the smooth rod 21 is symmetrically arranged.
[0024] In this embodiment, the smoothness of the contact between the smooth rod 21 and the wedge block 22 can be ensured by setting the smooth rod 21.
[0025] In this technical solution, the limiting component includes a limiting frame 3 disposed above the sleeve 12. The limiting frame 3 is movably connected to the sleeve 12. A lead screw sleeve 4 is fixedly installed on the upper end of the limiting frame 3. A lead screw 5 is welded to the upper end of the screw 23. The lead screw 5 is threadedly connected to the lead screw sleeve 4.
[0026] In this embodiment, the screw 23 rotates simultaneously, which drives the lead screw 5 to rotate. The lead screw 5, together with the lead screw sleeve 4, drives the limiting frame 3 to move downward, so that the left side of the limiting frame 3 is inserted into the handle 13, thereby achieving the limiting effect on the handle 13. After the anchor bolts are tightened, the limiting frame 3 is controlled to move upward, so that the limiting frame 3 is separated from the handle 13, thereby facilitating the rotation of the handle 13 and reducing the space occupied by the sleeve 12 and the handle 13.
[0027] In this technical solution, the size of the screw 23 is adapted to the size of the threaded groove 24, and the screw 23 and the threaded groove 24 are helically connected.
[0028] In this embodiment, the screw 23 cooperates with the threaded groove 24, thereby driving the adjusting ring 2 to move.
[0029] During adjustment, rotating the screw 23 causes the adjusting ring 2 to move downwards along the threaded groove 24. The adjusting ring 2 then moves the smooth rod 21 downwards, pushing the wedge block 22 against the outside of the anchor bolt. This allows for adaptive adjustment based on the anchor bolt size, facilitating the disassembly of anchor bolts of different sizes and improving the efficiency of tightening or loosening the anchor bolts. Simultaneously, the rotation of the screw 23 causes the lead screw 5 to rotate. The lead screw 5, in conjunction with the lead screw sleeve 4, moves the limiting frame 3 downwards, inserting its left side into the handle 13, thus limiting the handle 13. After the anchor bolt is tightened, the limiting frame 3 is moved upwards, separating it from the handle 13, facilitating rotation of the handle 13 and reducing the space occupied by the sleeve 12 and the handle 13.
