Description

Technical Field

[0001] This utility model belongs to the field of new energy equipment installation, specifically a fine-tuning device for pole connection. Background Technology

[0002] In the construction of new energy projects such as photovoltaic power plants and wind farms, it is usually necessary to vertically install and fix the upper poles supporting the photovoltaic system to the pre-cast base. Because photovoltaic systems are large outdoor structures, they need to withstand their own weight, wind and snow loads, and even seismic loads. If the poles are not vertical, they will become weak points in the structure, leading to uneven load distribution, which may eventually cause the entire photovoltaic system to overturn, resulting in serious safety accidents and economic losses. Therefore, the key to installation is to keep the poles vertical and ensure that the connection holes between the poles and the base are precisely aligned, facilitating the smooth insertion of the through bolts to complete the rigid connection between the poles and the base.

[0003] Currently, the alignment of the aforementioned connection holes is mostly adjusted manually using traditional methods. This involves construction workers manually moving and lifting the upper poles, repeatedly trying based on visual inspection and experience until the connection holes on the poles align with those on the base. This method has the following drawbacks: First, due to the significant weight of the poles, manual operation is extremely laborious and poses safety hazards. Second, manual adjustment is inaccurate and inefficient, requiring repeated trial and error, severely hindering construction progress. Furthermore, manual movement cannot guarantee that the poles will remain vertical; any tilting will cause hard scraping against the base, damaging its anti-corrosion coating and affecting structural durability. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a fine-tuning device for pole connection, so as to achieve the purpose of aligning the connection holes of the pole and the connection holes of the base in a labor-saving, precise, and efficient manner.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fine-tuning device for pole connection includes a first fixing member for fixing on the outer diameter of a base and a second fixing member for fixing on the outer diameter of a pole. An adjustment assembly is provided between the first and second fixing members. The adjustment assembly includes a threaded component, a transmission component, and a driving component. The threaded component is rotatably connected to the first fixing member, and the rotation axis of the threaded component is arranged in the vertical direction. The threaded component is threadedly connected to the second fixing member. The output end of the driving component is connected to the input end of the transmission component, and the output end of the transmission component is connected to the threaded component. Rotation of the threaded component causes the second fixing member to move vertically along the threaded component.

[0006] As a limitation of this utility model: the first fixing member and the second fixing member have the same structure. The first fixing member is a clamp, and the two semi-circular arc pieces of the clamp are arranged opposite each other to form a clamping space for clamping the base. The ends of the two semi-circular arc pieces are fastened by bolts and nuts respectively.

[0007] As a further limitation of this utility model, an elastic protective layer is fixedly provided on the inner surface of both semi-circular arc pieces.

[0008] As a further limitation of this utility model: the elastic protective layer is a rubber gasket.

[0009] As another limitation of this utility model: the threaded component is a lead screw, the bottom end of the lead screw is rotatably connected to the first fixed component through the lead screw seat, the second fixed component is fixedly provided with a moving block, the moving block is provided with an internal threaded hole extending in the vertical direction, the top end of the lead screw passes through the internal threaded hole and is threadedly connected to the moving block; the output end of the transmission component is connected to the lead screw.

[0010] As a further limitation of this utility model: the transmission component includes a first bevel gear and a second bevel gear, the output end of the drive component is connected to the first bevel gear, the first bevel gear meshes with the second bevel gear and the angle between their axes is 90°, and the lead screw is fixedly sleeved on the inner diameter of the second bevel gear.

[0011] As a further limitation of this utility model: the transmission component also includes a housing for covering the first bevel gear and the second bevel gear, and the top and bottom of the housing are provided with through holes for the lead screw to pass through; the first bevel gear is rotatably mounted on the side wall of the housing, and the second bevel gear is rotatably mounted on the bottom wall of the housing.

[0012] As a further limitation of this utility model: the driving component is a hand crank, and one end of the hand crank near the outer shell extends into the inner shell and is fixedly connected to the first bevel gear.

[0013] As another limitation of this utility model: the adjustment components are provided in two sets, and the two sets of adjustment components are symmetrically arranged about the central axis of the first fixing member.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: This invention inputs power through a driving component, which is then redirected by a transmission component, ultimately driving the threaded component to rotate. Because the threaded component is threadedly engaged with the second fixing component, which is fixedly fitted onto the outer diameter of the upright, when the threaded component rotates, the second fixing component, under the threaded engagement, drives the upright to move axially along the threaded component, i.e., vertically. This changes the relative position between the upright and the base, allowing construction personnel to observe the alignment of the connecting holes while making fine adjustments. This achieves rapid and precise alignment of the connecting holes, avoiding repeated trial and error, significantly shortening adjustment time, and substantially improving construction efficiency and installation quality. This invention requires only a small force on the driving component to lift or pull back the upright, greatly reducing labor intensity and eliminating safety hazards such as slippage and injury that may occur when manually moving the upright. In this invention, the upright remains vertical during adjustment, avoiding hard contact and direct scraping between the upright and the base, achieving non-destructive installation and extending the structural service life.

[0015] In summary, this utility model can complete the alignment of the pole connection hole and the base connection hole in a labor-saving, accurate, and efficient manner; this utility model is applicable to pole installation operations in the field of new energy. Attached Figure Description

Detailed Implementation

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0020] Example 1 like Figures 1-2As shown, this embodiment includes a first fixing member 1, a second fixing member 2, and an adjustment component. The adjustment component is used to adjust the relative position of the first fixing member 1 and the second fixing member 2 in the vertical direction, thereby adjusting the height of the upright 3 above the base 4, so as to achieve effortless, fast, and accurate alignment of the connection hole between the upright 3 and the base 4.

[0021] The first fixing member 1 is used to fix it onto the outer diameter of the base 4, and the second fixing member 2 is used to fix it onto the outer diameter of the upright 3. The first fixing member 1 and the second fixing member 2 have the same structure. In this embodiment, both the first fixing member 1 and the second fixing member 2 are existing clamps. The two semi-circular arc plates of the clamp are arranged opposite each other to form a clamping space for clamping the base 4 and the upright 3. The ends of the two semi-circular arc plates are fastened by bolts and nuts. In order to prevent the clamp from scratching the surface of the upright 3 and the base 4, an elastic protective layer is fixed on the inner surface of the two semi-circular arc plates. In this embodiment, the elastic protective layer is a rubber gasket. Of course, any elastic non-metallic material in the prior art can also be selected.

[0022] In this embodiment, the first fixing member 1 and the second fixing member 2 are clamps, which can be fixed to the base 4 and the upright 3, providing a foundation for the installation of the adjustment component; and can also be removed from the base 4 and the upright 3 after the upright 3 is adjusted into place. In this embodiment, the first fixing member 1 and the second fixing member 2 can also adopt any other structure in the prior art, as long as it can ensure that there is no relative displacement with the upright 3 and the base 4 after installation, and that it can be removed from the upright 3 and the base 4 later.

[0023] The adjustment assembly is located between the first fixing member 1 and the second fixing member 2. The adjustment assembly includes a threaded component 5, a transmission component, and a driving component.

[0024] like Figure 1 As shown, the threaded component 5 is rotatably connected to the first fixed component 1. The rotation axis of the threaded component 5 is set in the vertical direction. The threaded component 5 is threadedly connected to the second fixed component 2. Rotation of the threaded component 5 causes the second fixed component 2 to move vertically along the threaded component 5. In this embodiment, the threaded component 5 is a lead screw, and the external thread on the lead screw is not shown in the figure. The bottom end of the lead screw is rotatably connected to the first fixed component 1 through the lead screw seat 6. A moving block 7 is fixed on the second fixed component 2. The moving block 7 is provided with an internally threaded hole extending in the vertical direction. In other words, the internally threaded hole penetrates the upper and lower surfaces of the moving block 7. The top end of the lead screw passes through the internally threaded hole and is threadedly connected to the moving block 7. When the lead screw rotates, the upright 3 and the moving block 7 tend to rotate with the lead screw. However, because the bottom end of the upright 3 is located inside the base 4, it cannot rotate. At this time, under the threaded engagement of the moving block 7 and the lead screw, the moving block 7 drives the upright 3 to move linearly along the axis of the lead screw. At this time, after observing that the connecting hole of the upright 3 is aligned with the connecting hole of the base 4, the two can be fixed by using the through bolt 8.

[0025] The output end of the transmission component is connected to threaded component 5, that is, the output end of the transmission component is connected to a lead screw, which is used to drive the lead screw to rotate. For example... Figure 2 As shown, the transmission component includes a first bevel gear 9 and a second bevel gear 10, with the output end of the transmission component being the second bevel gear 10. The first bevel gear 9 meshes with the second bevel gear 10, and the angle between their axes is 90°. The lead screw is fixedly sleeved on the inner diameter of the second bevel gear 10. Figure 1 , 2 As shown, the transmission component also includes a housing 11 for covering the first bevel gear 9 and the second bevel gear 10, serving both dustproof and aesthetic purposes. The top and bottom of the housing 11 are provided with through holes for the lead screw to pass through; the size of the through holes is slightly larger than the size of the lead screw. The first bevel gear 9 is rotatably mounted on the side wall 111 of the housing 11, and the second bevel gear 10 is rotatably mounted on the bottom wall 112 of the housing 11. The method of achieving transmission using a bevel gear set is existing technology.

[0026] The output end of the drive component is connected to the input end of the transmission component, that is, the output end of the drive component is connected to the first bevel gear 9. In this embodiment, the drive component is a hand crank 12, and one end of the hand crank 12 near the outer casing 11 extends into the inner casing 11 and is fixedly connected to the first bevel gear 9.

[0027] When using this embodiment, the construction personnel observe the misalignment between the connecting holes at the bottom of the upright 3 and the connecting holes of the base 4. If it is necessary to raise the upright 3 to align the connecting holes, a lifting operation is performed. Specifically, the hand crank 12 is rotated clockwise, the first bevel gear 9 rotates with the hand crank 12, causing the second bevel gear 10 to mesh and drive the transmission. The second bevel gear 10 drives the lead screw to rotate, at which time the moving block 7 drives the upright 3 to rise.

[0028] If it is necessary to lower the upright pole 3, a pull-back operation is performed. Specifically, the hand crank 12 is rotated counterclockwise, the first bevel gear 9 rotates with the hand crank 12, causing the second bevel gear 10 to mesh and drive. The second bevel gear 10 drives the lead screw to rotate, and at this time the moving block 7 drives the upright pole 3 to descend.

[0029] After observing that the connecting holes at the bottom of the upright 3 are aligned with the connecting holes of the base 4, immediately insert the through bolt 8 from one side of the connecting hole in the base 4 and out the other side, then tighten it with the nut to complete the rigid connection between the upright 3 and the base 4. Finally, tighten the three set screws 13. The through bolt 8 and set screws 13 are used to fix the upright 3 and the base 4 and are existing technologies.

[0030] During the use of this embodiment, construction personnel can make fine adjustments while observing the alignment of the connecting holes, achieving rapid and accurate alignment of the connecting holes, avoiding repeated trial and error, significantly shortening adjustment time, and significantly improving construction efficiency and installation quality. This invention requires only a small force to be applied to the driving component to lift or pull back the upright 3, greatly reducing labor intensity and eliminating safety hazards such as slippage and injury that may occur when manually moving the upright 3. In this invention, the upright 3 remains vertical during adjustment, avoiding hard contact and direct scraping between the upright 3 and the base 4, achieving non-destructive installation and extending the service life of the structure.

[0031] It should be noted that the adjustment component in this embodiment can also adopt any other structure in the prior art, as long as it can complete the vertical lifting and lowering of the pole 3.

[0032] Example 2 This embodiment has a basically the same structure as Embodiment 1, the difference being that, as Figure 3 As shown, in this embodiment, two sets of adjustment components are provided, and the two sets of adjustment components are symmetrically arranged about the central axis of the first fixing member 1. In other words, the two sets of adjustment components are symmetrical about the central axis of the upright 3. The specific structure of the adjustment components is the same as in Embodiment 1. This application provides two symmetrical sets of adjustment components, so that both hands can simultaneously crank the hand crank 12 during use, and the moving blocks 7 on both sides of the upright 3 jointly drive the upright 3 to move vertically, which is more labor-saving.

[0033] The usage process of this embodiment is described in Embodiment 1.

[0034] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
