[0002] Prestressed electric poles are usually made of high-strength materials such as steel or high-performance composite materials. They are subjected to a pre-stress treatment during manufacturing, which creates an initial stress state within the material. This pre-stress helps to counteract external stresses when they are applied, reducing material deformation and damage. Prestressed electric poles have characteristics such as high strength, seismic resistance, corrosion resistance, and long lifespan. These poles are widely used in high-voltage transmission lines, support structures for transmission towers, and critical parts of power transmission. Their high strength and seismic resistance ensure reliable operation under adverse weather conditions or high loads.

The lengthening position generally uses a flange plate plus reinforcement connection method, and the flange plate used for lengthening needs to be processed according to requirements. When the flange plate used for lengthening is processed and punched, how to tension, fix and clamp the flange plate for processing needs to be carefully considered. SUMMARY

[0007] One end of the tension limiting caliper close to the limiting channel is movably connected to the side wall of the limiting channel.
[0008] Preferably, the side wall of the limiting channel is provided with a limiting movable channel corresponding in number to the tension limiting calipers, and one end of the tension limiting caliper close to the limiting movable channel is movably connected to the limiting movable channel.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] Example 1
[0023] like Figures 1 to 5 As shown, a prestressed pole flange tensioning device is used to tension and clamp the flange used for extending prestressed poles. Structurally, the device includes a tension clamping base 1, with a tension clamping seat 2 detachably connected to the top of the base 1. The tension clamping seat 2 has a through-hole for limiting the flange, and several movable tension limiting structures are installed around the limiting channel. Each tension limiting structure includes a tension limiting clamp 3, which moves closer together to tension and clamp the flange placed between them. The end of each tension limiting clamp 3 near the limiting channel is movablely connected to the side wall of the limiting channel.
[0024] In this embodiment, according to processing requirements, the required tension clamping seat 2 is installed and connected to the tension clamping fixed base 1. Specifically, the tension clamping seat 2 is connected to two limit blocks 21 on both sides of one end face near the tension clamping fixed base 1. The tension clamping fixed base 1 has limit mounting slots corresponding to the number of limit blocks 21. The limit blocks 21 are used to pass through the limit mounting slots and are movably limited within the limit mounting slots. Furthermore, limit mounting holes are also provided around the perimeter of the tension clamping seat 2, through which limit bolts 22 are inserted. The tension clamping seat 2 is threadedly connected to the tension clamping fixed base 1 via the limit bolts 22. To facilitate quick alignment and installation, an installation limiting channel is provided on the tension clamping and fixing base 1. A limiting cylinder coaxially arranged with the limiting channel is connected to the bottom end of the tension clamping base 2. During installation and connection, the limiting cylinder is placed in the limiting channel, and then the limiting block 21 is inserted into the limiting installation groove to achieve quick installation and connection.
[0025] After the tension clamping seat 2 is installed and connected to the tension clamping fixed base 1, the farad plate to be processed is placed in the limiting channel opened through the tension clamping seat 2; then the tension limiting calipers 3 are controlled to move closer to each other, and the farad plate placed between the tension limiting calipers 3 is tensioned and clamped to facilitate processing, drilling, etc.
[0026] Embodiment 2
[0027] On the basis of embodiment 1, the side wall of the limiting channel is provided with a limiting movable channel corresponding to the number of the tension limiting calipers 3, and the end of the tension limiting caliper 3 close to the limiting movable channel is movably connected with the limiting movable channel. At the same time, the end of the tension limiting caliper 3 close to the limiting movable channel is respectively connected with a bearing 31, and the tension limiting caliper 3 is movably connected with a movable adjusting screw 32 through the bearing 31; the end of the movable adjusting screw 32 away from the tension limiting caliper 3 is movably passed through the movable channel and rotatably passed through the side wall of the tension clamping seat 2, and the end of the movable adjusting screw 32 away from the tension limiting caliper 3 is connected with an adjusting handle for conveniently driving the movable adjusting screw 32 to rotate. And the two sides of the tension limiting caliper 3 are respectively connected with a limiting guide sliding block 33, the two side walls of the limiting movable channel are respectively provided with a limiting guide sliding groove, and the limiting guide sliding block 33 is slidingly limited and matched with the limiting guide sliding groove.
[0028] When the tension limiting structure is relatively close to the flange plate placed between each tension limiting structure and is adjusted to be tension clamped, each movable adjusting screw 32 is driven to rotate along the side wall of the tension clamping seat 2 by holding the adjusting handle; the tension limiting caliper 3 is slidingly guided by the limiting guide sliding block 33 and the limiting guide sliding groove, and each tension limiting caliper 3 is pushed to be relatively movable by the movable adjusting screw 32, so as to tension clamp the flange plate placed between the tension limiting calipers 3. The flange plate used for prestressed electric pole lengthening can be conveniently tension clamped and fixed by the tension device, so as to process, punch and operate the flange plate, thereby saving the processing time and improving the processing efficiency.
