[0002] Pole tower testing equipment is commonly used to test the performance and quality of transmission towers. Power towers are heavy and subject to significant wind resistance in their operating environments. In practice, these towers are typically fixed to the ground. However, testing power equipment often requires moving the towers, making this type of fixed tower installation time-consuming and labor-intensive.

[0003] Existing mobile tower test platforms also face numerous challenges. For example, the towers used in experiments are often large and tall, subject to strong winds during movement. This makes it difficult to ensure the towers remain stable and prevent them from tipping over during movement. Furthermore, the tower test platforms cannot be stopped or restarted immediately while in motion. Therefore, a new tower test platform is needed to address these challenges. Summary of the Invention

[0037] Specifically, the fixing component 4 is used to firmly connect the pole tower 3 and the moving vehicle body 2, and the moving vehicle body 2 can move along the fixed guide rail 1. The driving component 22 can drive the moving platform 21 to move and stay at a predetermined position. However, due to the large weight and high height of the pole tower 3, the wind resistance in the high altitude is large and it is prone to tipping. The anti-tipping component 23 is provided on the moving vehicle body 2, and the anti-tipping component 23 can lock the moving platform 21 and the fixed guide rail 1, so as to resist strong wind weather, and at the same time make the device applicable to testing the pole tower 3 in harsh environments. Among them, the anti-tipping component 23 includes a fixed sleeve 231, and in this embodiment, the fixed sleeve 231 is in an inverted "U" shape. The first anti-tipping foot 232 and the second anti-tipping foot 233 are stuck in the fixed sleeve 231. In this device, the first anti-tipping foot 232 and the second anti-tipping foot 233 can be in an integrated form or a split form. Specifically, the upper parts of the first anti-tipping foot 232 and the second anti-tipping foot 233 can be connected as a whole for easy installation; or the first anti-tipping foot 232 and the second anti-tipping foot 233 can be set in a split form for easy processing.

During the movement of the pole tower 3, the clamping groove 2321 and the clamping protrusion 11 are loosened so that the pole tower 3 can move freely. When conducting experiments on the pole tower 3 or in strong wind weather, the clamping groove 2321 and the clamping protrusion 11 are locked, thereby improving the safety of the operator and the pole tower 3 itself.

[0038] See Figure 3 and Figure 4The drive assembly 22 includes a motor 221, a reducer 222 connected to the motor 221, a crankshaft 223 connected to the reducer 222, and a pulley 224 connected to the crankshaft 223; the crankshaft 223 is connected to the mobile platform 21 via a bearing seat 225, and the pulley 224 is arranged in cooperation with the fixed guide rail 1. Specifically, the motor 221 is arranged in the box-type mobile platform 21, and the motor 221 can be started by remote control.

The other end of the crankshaft 223 passes through the bearing seat 225 and is connected to the pulley 224. To prevent the pulley 224 from derailing, a flange 2241 is provided on the pulley 224. The flange 2241 abuts against the inner sidewall of the fixed guide rail 1, thereby limiting the movement direction of the pulley 224 and improving the movement reliability of the drive assembly 22. Furthermore, two sets of drive assemblies 22 are provided. The two sets of drive assemblies 22 are symmetrically mounted on the mobile platform 21.

[0039] See also Figure 5 To improve the safety of the drive assembly 22, both ends of the fixed guide rail 1 are equipped with soft limit devices (not shown in the drawings) and mechanical limit devices 5. The soft limit devices include a proximity switch on the fixed guide rail 1 and a proximity switch sensor on the mobile platform 21. Upon sensing the proximity switch sensor, the proximity switch sends a signal, controlling the operation of the motor 221 via the driver. The mechanical limit devices 5 are mechanical limit blocks 51 located at both ends of the fixed guide rail 1. These mechanical limit blocks 51 prevent the mobile vehicle 2 from derailing.

To accommodate various towers 3 sizes, a flange 31 is provided on the bottom surface of the tower 3. These flanges are of the same model, enhancing the versatility of the device and enabling multiple uses with one vehicle. The flange mount 41 and flange 31 are bolted together, enabling quick connection between the tower 3 and the mobile platform 21.

[0042] Furthermore, the flange seat 41 is provided with at least two positioning grooves 411. The positioning grooves 411 are provided on the inner wall of the flange seat 41, and the flange plate 31 is provided with positioning blocks 311 adapted to fit within the positioning grooves 411. The positioning blocks 311 cooperate with the positioning grooves 411 to offset circumferential forces, thereby preventing the tower 3 from rotating.

[0043] See also Figure 5 and Figure 6 The fixing assembly 4 also includes a stay rigging 42, which includes a lifting lug 421 connected to the upper surface of the mobile platform 21, a first stay cable ring 43 connected to the lifting lug 421, a pull rope 422 connected to the first stay cable ring 43, and a second stay cable ring 44 connected to the pull rope 422.

The inclined clamp 45 is fixed on the tower 3. Through the joint action of multiple groups of inclined rigging 42, the tower 3 is kept in a stable vertical state and can withstand winds from multiple directions.

[0044] To facilitate securing the inclined-stay clamp 45 to the tower 3, the inclined-stay clamp 45 comprises a first semicircular tube clamp 451 and a second semicircular tube clamp 452, which are connected via bolts 453. The inner diameter formed by the first and second semicircular tube clamps 451, 452 matches the inner diameter of the tower 3, and the bolts 453 enable quick connection between the first and second semicircular tube clamps 451, 452. Furthermore, to accommodate towers 3 of various diameters, the first and second semicircular tube clamps 451, 452 are removable from the second inclined-stay cable ring 44. Furthermore, in order to prevent the first semicircular tube clamp 451 and the second semicircular tube clamp 452 from sliding relative to the pole tower 3, an oblique boss 46 for positioning the oblique clamp 45 is also provided below the oblique clamp 45. The oblique boss 46 is fixedly connected to the pole tower 3 to prevent the oblique clamp 45 from moving downward, thereby improving the stability of the device.

[0045] The first oblique cable ring 43 includes a grommet 431, a buckle 432 that engages with the grommet 431, and a pin 433 for securing the grommet 431 to the lug 421 or the pull rope 422.
