[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0013] Example 1

[0014] like Figure 1 As shown, a guy wire fixing device for a portal tower load-bearing capacity test includes a fixing block 1, which is a rectangular weight with a set weight. Fixing plates 2 extend outwards from the bottom of both ends of the fixing block 1. A locking screw 3 is fixedly connected upwards to the middle of the fixing plate 2. Multiple counterweight plates 4 are fitted onto the locking screw 3 and secured with locking nuts 5. The fixing block 1 serves as the fixing device for the end of the guy wire. First, the position of the fixing block 1 is adjusted according to the position of the portal tower and the length of the guy wire. Then, counterweights are installed on the fixing plates 2 to increase the weight of the fixing block, preventing excessive tension and displacement, which could lead to uneven tension on both sides of the portal tower, affecting the tower's balance and stability.

[0015] To facilitate the movement of the fixed block 1, two longitudinally symmetrical grooves 6 are provided on the bottom of the fixed block 1. The fixed block 1 is slidably connected to the ground slide rail through the grooves 6. The slide rail is perpendicular to the direction of the portal tower and has a guiding function, ensuring that the fixed block 1 is always directly facing the center of the portal tower without shifting to the left or right, thus ensuring that the two guy wires on one side are evenly stressed. A screw nut seat 7 is installed on both sides of the groove 6 on the front of the fixed block 1. A screw rod 8 is spirally connected inside the screw nut seat 7. One end of the screw rod 8 extends horizontally towards the slide rail and is fixedly connected to a limiting plate 9. The limiting plate 9 faces the slide rail and has a rubber layer 10. The other end of the screw rod 8 has a rotating handle 11. By operating the rotating handle 11, the screw rod rotates, and the limiting plate 9 moves closer to the middle slide rail until it clamps the slide rail, thus fixing the fixed block 1.

[0016] The locking nut 5 and the counterweight plate 4 are provided with a pressing plate 12, so that the stress is evenly loaded on the counterweight plate 4, and the locking reliability is better.

[0017] The top end of the fixing block 1 is provided with a connecting block 13 near the two sides, the connecting block 13 is hingedly connected with a fixing ring 14, the fixing ring 14 is sleeved with a connecting rod 15, the connecting rod 15 is provided with a tension sensor, the top end of the connecting rod 15 is provided with a thread, and is screwed with a nut 16 provided with a connecting ring 17, the end of the pull wire is connected with the connecting ring 17 through a hook, so that the pull wire is fixed conveniently and quickly in a replacement of a binding mode, and the connection reliability is better.

[0018] The above-described embodiments are only used to describe the preferred embodiments of the utility model, and do not limit the scope of the utility model.
