[0033] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0034] In view of this, a pole straightening device is provided according to a first aspect of the embodiments of this application, including a base 1, a jacking pipe 2 and a jack support 11.

[0035] like Figure 1 As shown, the jack support 11 is connected to the base 1 and is used to install the jack 8; one end of the jacking pipe 2 is located at the end of the jack 8 away from the jack support 11; the other end of the jacking pipe 2 is used to support the utility pole. During operation, the operator raises the jack 8, thereby pushing the utility pole back to its upright position via the jacking pipe 2. Since the jacking pipe 2 needs to support the utility pole with the jack 8 as a fulcrum, the jack 8 must be stable. To prevent the jack 8 from moving or tipping over, the jack support 11 is provided to ensure a stable connection between the jack 8 and the base 1.

[0036] Preferably, the jack 8 is a hydraulic jack, which can make it easier for workers to operate.

[0037] Furthermore, the jacking device also includes a jacking pipe guide structure. The jacking pipe guide structure is used to support the jacking pipe 2 and guide the jacking pipe 2.

[0038] Preferably, in one embodiment, such as Figure 1 , Figure 2 As shown, the jacking pipe guide structure includes a first support rod 31, a second support rod 32, and a first bracket 41. The first support rod 31 and the second support rod 32 are connected in parallel to the base 1, and the angle between the plane containing the first support rod 31 and the second support rod 32 and the base 1 is an acute angle. One end of the first bracket 41 is connected to the first support rod 31, and the other end is connected to the second support rod 32. The space inside the acute angle formed between the plane containing the first support rod 31 and the second support rod 32 and the base 1 is a first space. The jack 8 is located within the first space. The jacking pipe 2 is slidably mounted on the first bracket 41.

[0039] Specifically, the first support rod 31 and the second support rod 32 are inclined, and their inclination is approximately the same as that of the jacking pipe 2. The first bracket 41, which is horizontally positioned between the first support rod 31 and the second support rod 32, can support the jacking pipe 2 in the vertical direction to prevent the inclined jacking pipe 2 from tipping over due to its unstable state.

[0040] Furthermore, the jacking pipe guide structure also includes a second support 42. One end of the second support 42 is connected to the end of the first support rod 31 away from the base 1; the other end of the second support 42 is connected to the end of the second support rod 32 away from the base 1; the jacking pipe 2 is slidably mounted on the first support 41 and the second support 42. Specifically, the second support 42 provides an additional fulcrum for supporting the jacking pipe 2, making the jacking pipe 2 more stable when tilted.

[0041] Furthermore, because the inclined first support rod 31 and second support rod 32 are subjected to extremely high forces throughout the operation, in order to prevent them from breaking due to stress, in one embodiment, a first support plate 311 and a second support plate 321 are also provided. One end of the first support plate 311 is connected to the first support rod 31, and the other end is connected to the base 1; one end of the second support plate 321 is connected to the second support rod 32, and the other end is connected to the base 1; both the first support plate 311 and the second support plate 321 are located within the first space. Preferably, the first support plate 311 is triangular, with one side connected to the first support rod 31 along its length direction, and the other side perpendicularly connected to the base 1; the second support plate 321 is similarly designed. The arrangement of the first support plate 311 and the second support plate 321 can effectively support the first support rod 31 and the second support rod 32 in the vertical direction, preventing them from breaking due to stress.

[0042] Furthermore, the jacking pipe guide structure also includes a limiting member. The limiting member is connected to the first support 41 and the second support 42, and is used to limit the jacking pipe 2 disposed on the first support 41 and the second support 42 in the vertical and horizontal directions.

[0043] Preferably, in one embodiment, the limiting member includes a first guide tube 51 and a second guide tube 52. The first guide tube 51 is connected to the first bracket 41; the second guide tube 52 is connected to the second bracket 42; the top tube 2 passes through the first guide tube 51 and the second guide tube 52 and is disposed on the first bracket 41 and the second bracket 42.

[0044] During operation, as the jack 8 rises and the pole's tilt changes, the jacking pipe 2 needs to adjust its tilt within a certain range to more stably support the pole and transmit maximum thrust from the jack 8 to the pole. Therefore, the first guide cylinder 51 and the second guide cylinder 52 limit the jacking pipe 2 in three aspects.

[0045] First, the first guide cylinder 51 and the second guide cylinder 52 support the jacking pipe 2 in the vertically upward direction, preventing it from tilting downwards when it is too tilted. Second, the first guide cylinder 51 and the second guide cylinder 52 restrict the jacking pipe 2 in the vertically downward direction. When the jacking pipe 2 uses the jack 8 as a fulcrum, and its tilt gradually approaches the vertical direction as the jack 8 is raised and the tilt of the pole itself changes, at a certain point, the first guide cylinder 51 and the second guide cylinder 52 can control it to no longer change in the vertical direction, thus preventing the pole from losing its load. At this time, the workers can adjust the position of the base 1 in time so that the entire pole straightening device can continue to work smoothly. Third, on the horizontal plane, the jacking pipe 2 may slide left and right under load, causing one end of it supporting the pole to slip off the pole surface, thus causing the pole to lose its load and collapse again. The first guide cylinder 51 and the second guide cylinder 52 restrict the left and right sliding of the jacking pipe 2 in the horizontal direction.

[0046] Furthermore, in one embodiment, the straightening device also includes a jacking pipe support 81. The jacking pipe support 81 is connected to the end of the jack 8 away from the jack support 11; a groove 811 is provided on the side of the jacking pipe support 81 away from the jack 8; the end of the jacking pipe 2 away from the pole is disposed in the groove 811. During operation, the jacking pipe 2 supports the pole with the jack 8 as a fulcrum. Therefore, the end of the jacking pipe 2 on the jack 8 cannot be fixed, but it must be able to limit its movement to prevent it from sliding under force. The groove 811 allows the jacking pipe 2 to rotate in all directions while preventing it from sliding.

[0047] Furthermore, the straightener also includes a base fixing component. The base fixing component is used to fix the base 1 to the ground.

[0048] Preferably, in one embodiment, the base fixing member includes a bottom insert 12. The bottom insert 12 is connected to the surface of the base 1 away from the jack support 11 along a first direction; the first direction is parallel to the line connecting the first support rod 31 and the second support rod 32. During operation, the jacking pipe 2 exerts a very large thrust on the pole, which may cause the base 1 to be unstable on the ground. The bottom insert 12 can be inserted into the ground to maintain the stability of the base 1.

[0049] Preferably, there can be multiple bottom inserts 12 to ensure that the base 1 is more stable.

[0050] Furthermore, since the pole straightening device of this application is heavy and needs to be transported frequently, and may even need to be transported to some areas with inconvenient transportation or complex terrain, in one embodiment, the pole straightening device also includes a transport component.

[0051] Preferred, such as Figure 2 As shown, the transport component includes a roller bracket 13, a roller 14, and a roller 6. One end of the roller bracket 13 is connected to the base 1 and is located on the side outside the acute angle formed between the plane containing the first support rod 31 and the second support rod 32 and the base 1. The other end of the roller bracket 13 extends away from the first support rod 31 and the second support rod 32 and is connected to the roller 14. The roller 14 is arranged along the first direction. The roller 6 is rotatably connected to the roller 14, and when the base 1 is placed on the ground, the roller 6 does not contact the ground. When transport is required, the operator moves the first support rod 31 and the second support rod 32 in the opposite direction to the tilt direction of the first support rod 31 and the second support rod 32, causing the base 1 to tilt up, and the roller 6 to contact the ground, thus easily dragging the entire uprighting device to the required position.

[0052] Preferably, multiple rollers 6 can be provided to facilitate transportation.

[0053] Furthermore, the transport component also includes a first handle 71 and a second handle 72. The first handle 71 is connected to the end of the first support rod 31 away from the base 1 and is located on the side of the first support rod 31 away from the second support rod 32; the second handle 72 is connected to the end of the second support rod 32 away from the base 1 and is located on the side of the second support rod 32 away from the first support rod 31. The arrangement of the first handle 71 and the second handle 72 makes it easier for workers to operate and drag the integral straightening rod.

[0054] Furthermore, for ease of transportation, this embodiment makes the jacking pipe 2 detachable. For example... Figure 3 As shown, the jacking pipe 2 includes a first pipe section 21, a second pipe section 22, and connecting parts.

[0055] Preferably, in one embodiment, the connector is a connecting nut 23. Both the first pipe section 21 and the second pipe section 22 are threadedly connected to the connecting nut 23. It should be noted that various existing stable connection methods can be used here without limitation.

[0056] According to a second aspect of the embodiments of this application, a straightening system is provided, including a jack 8 and a straightening device as described in any of the above technical solutions. Therefore, this straightening system possesses all the beneficial effects of the straightening devices described in the above technical solutions, which will not be elaborated upon here.
