[0002] A pole base fixing device is a device used to secure utility poles. Its purpose is to ensure the pole's stability and fixation on the ground, preventing it from tilting or collapsing.

[0003] The pole base fixing device also plays a role in positioning and fixing the pole during installation. When installing the pole, a hole is usually dug at the installation site first, and then the base fixing device is placed in it. After the base fixing device is in place and fixed, the pole is vertically inserted into the mounting hole of the fixing device, and finally the soil is used to fix it.

[0004] The bottom of the installation pit dug manually or by machine may not be flat. Therefore, when the root fixing device is installed in the pit, it is easy for the angle to tilt and it is not easy to adjust. This will cause the utility pole fixed by the root fixing device to be in a tilted state, or even to fall over, which poses a safety hazard. Summary of the Invention

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0041] Example 1

[0042] like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a front view of the fixing device. Figure 2 The diagram shown is a top view of the fixed device.

[0043] The device includes a base plate 11 and an elastic clamp 12. Multiple support rods 13 connecting the base plate 11 and the elastic clamp 12 are arranged in an array between them. A fixing block 14 is also provided at the upper end of the base plate 11. The base plate 11, the elastic clamp 12 and the fixing block 14 are all provided with through mounting holes for inserting power supply rods, and each mounting hole corresponds in the vertical direction.

[0044] During installation, the base of the utility pole passes through the elastic clamp 12, the fixing block 14, and the base plate 11 in sequence before finally being inserted into the soil. The fixing block 14 and the base plate 11, as well as the support rod 13 and the elastic clamp 12 and the base plate 11, are all fixedly connected. The fixing block 14 serves as a counterweight for reinforcement and can be made of concrete. The elastic clamp 12 serves to hold and fix the utility pole in place, and the support rod 13 provides support for the elastic clamp 12, making the device more stable.

[0045] Mounting slots are provided on both the front and rear side walls of the fixed block 14. An observation component is installed inside the mounting slot. The observation component includes a pointer 21 and an indicator ruler 22. The pointer 21 is vertically suspended in the mounting slot by a traction rope. The indicator ruler 22 is horizontally set at the indicating end of the pointer 21, and the pointer 21 points vertically to the center line of the indicator ruler 22 when the base plate 11 is horizontal.

[0046] The observation component serves to facilitate staff observation of whether the device tilts during or after installation. When the base plate 11 is perpendicular to the ground, the pointer 21 points to the center line of the indicator ruler 22 under the action of gravity. If the position indicated by the pointer 21 deviates, it indicates that the base plate 11 has tilted during installation.

[0047] like Figure 1 , Figure 3 , Figure 6 As shown, Figure 1 The diagram shown is a front view of the fixing device. Figure 3 The diagram shown is a front view of the adjustable support legs. Figure 6 What is shown is Figure 5 A cross-sectional view.

[0048] It also includes adjustable feet 30, which are located at the four corners of the lower end of the base plate 11. The adjustable feet 30 include a housing 31, and a sleeve 32 is rotatably provided on the outer bottom end face of the housing 31. A screw 33 is threadedly connected to the bottom end of the sleeve 32.

[0049] Sleeve 32 and screw 33 serve as temporary fixation during the installation of this device. When in use, the bottom end of screw 33 is placed against the soil, or screw 33 is clamped with a tool to restrict its rotation, and then sleeve 32 is rotated to allow screw 33 to extend downward and drill into the soil, temporarily stabilizing the device and facilitating the subsequent adjustment of the installation angle.

[0050] The upper end of the sleeve 32 is fixedly provided with an annular plate 1 and an annular plate 2 in sequence. The diameter of the annular plate 1 is smaller than that of the annular plate 2. The annular plate 2 is located at the bottom of the housing 31. The annular plate 1 is located in the annular groove opened at the bottom of the housing 31. The sleeve 32 and the housing 31 are rotated by setting the annular plate 1 and the annular plate 2.

[0051] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, Figure 1 The diagram shown is a front view of the fixing device. Figure 4 The diagram shown is a side view of the adjustable feet. Figure 5 The diagram shown illustrates the opening of the door with adjustable feet. Figure 6 What is shown is Figure 5 A cross-sectional view.

[0052] A rotating door 34 is provided on one side wall of the housing 31. A lifting assembly 40 is provided inside the housing 31. A connecting plate 35 is also provided at the upper end of the housing 31. The upper end of the connecting plate 35 is fixedly connected to the base plate 11, and the lower end of the connecting plate 35 is connected to the lifting assembly 40. The lifting assembly 40 drives the connecting plate 35 to move up and down to adjust its position, thereby adjusting the base plate 11 to a horizontal state.

[0053] The lifting assembly 40 includes a gear 41, a fixed frame 42, and a lifting column 43. The gear 41 is vertically rotatable on the door body 34 near the interior of the housing 31. The fixed frame 42 and the lifting column 43 are both located inside the housing 31. The upper and lower ends of the fixed frame 42, as well as the end near the gear 41, are open. The lifting column 43 is slidably mounted within the fixed frame 42. A rack 44 is provided at the end of the lifting column 43 near the gear 41, and the rack 44 corresponds to and meshes with the position of the gear 41 when the door body 34 is open. A handle is provided on the outer wall of the door body 34 at the position corresponding to the gear 41, and the handle is fixedly connected to the gear 41. When the door body 34 is closed, the gear 41 on the door body 34 does not interfere with the lifting column 43 or the rack 44.

[0054] The lifting assembly 40 controls the height of the adjustable support legs 30. When the door 34 is opened, the rotation of the gear 41 drives the meshing rack 44 and lifting column 43 to move stably up and down along the fixed frame 42, thereby adjusting the height of the four corners of the base plate 11. Combined with the observation assembly, this ensures that the device remains as vertical as possible to the bottom of the pit, preventing the fixed utility pole inside from tilting. By designing the door 34 and the lifting assembly 40 together, the lifting assembly 40 is designed to be concealed, providing some protection for related components during later pit filling and facilitating the reuse of the device.

[0055] like Figure 8 As shown, Figure 8 The diagram shown is a top view of the fixed frame and the rising column working together.

[0056] The lifting column 43 is provided with sliders 431 on its front and rear side walls, and the fixed frame 42 is provided with grooves 421 on its front and rear inner walls corresponding to the positions where the sliders 431 move up and down. By setting the sliders 431 and the grooves 421 to cooperate, the lifting column 43 can be stably raised or lowered.

[0057] like Figure 5 , Figure 6 , Figure 7 , Figure 9 As shown, Figure 5 The diagram shown illustrates the opening of the door with adjustable feet. Figure 6 What is shown is Figure 5 sectional view diagram, Figure 7 The diagram shown is of the gear locking state. Figure 9 The diagram shown is an enlarged structural schematic at point A.

[0058] It also includes a locking assembly 50, which includes a first locking element 51 and a second locking element 52. The first locking element 51 is located inside the door body 34 and on the side of the gear 41 away from the lifting column 43. The second locking element 52 is located on the outer periphery of a section extending from the upper end of the lifting column 43 out of the housing 31. The locking assembly 50 serves to fix the height of the adjustable support leg 30.

[0059] The locking component 51 includes a toothed plate 512 that is slidably disposed on the inner wall of the door body 34 and parallel to the rack 44. Limit blocks 513 are provided on the upper and lower ends of the toothed plate 512 near the gear 41. An electric push rod 511 is also provided on the end of the toothed plate 512 away from the gear 41. The output end of the electric push rod 511 is fixedly connected to the toothed plate 512.

[0060] The electric push rod 511 drives the toothed plate 512 to move closer to or away from the gear 41. In the initial state, the toothed plate 512 is away from the gear 41, and the gear 41 only meshes with the rack 44 on the other side. Rotating the gear 41 can smoothly drive the lifting column 43 to move up and down. After the height is adjusted, the electric push rod 511 is turned on, which drives the toothed plate 512 to move closer to the gear 41 until it meshes with it. The upper and lower ends of the toothed plate 512 are locked into the L-shaped limiting block 513, which restricts the rotation of the gear 41 and fixes its state.

[0061] Locking component 2 52 includes a fixing ring 521, which is set on the outer periphery of a section extending from the upper end of the lifting column 43 out of the housing 31. Sleeve 2 522 is horizontally rotatably inserted into the two opposite side walls of the fixing ring 521. Screw 2 523 and abutment plate 524 are sequentially arranged at the end of sleeve 2 522 near the lifting column 43. Screw 2 523 is threadedly connected to sleeve 2 522. Abutment plate 524 is slidably connected to the upper end face of the housing 31. Anti-slip texture is provided at the end of abutment plate 524 near the lifting column 43.

[0062] The locking component 52, located on the outer periphery of one end of the lifting column 43, secures the lifting column 43 by abutting and clamping it against the outer periphery of the lifting column 43 through the abutting plate 524. The abutting plate 524 is a plate with the same shape as the lifting column 43 to facilitate better contact with the outer surface of the lifting column 43. Anti-slip texture is provided to further increase the friction between the abutting plate 524 and the lifting column 43 in direct contact.

[0063] Rotating the second sleeve 522 causes the abutment plate 524 connected to the second screw 523 to slide on the upper surface of the housing 31, moving closer to or away from the lifting column 43, thus switching between fixed states.

[0064] like Figure 2 , Figure 10 As shown, Figure 2 The diagram shown is a top view of the fixing device. Figure 10 The diagram shown is a top-section schematic of the elastic clamp 12.

[0065] The elastic clamp 12 includes an annular clamp plate one and an annular clamp plate two arranged sequentially from the outside to the inside. The inner side of the annular clamp plate two is arranged with an arc-shaped clamping plate 121. The arc-shaped clamping plate 121 is movably inserted into the annular clamp plate two in the horizontal direction through a movable rod 122 fixedly connected to it. The end of the annular clamp plate two near the annular clamp plate one is provided with a mounting frame corresponding to the position of the movable rod 122. The movable rod 122 passes through the annular clamp plate two and is movably connected to the mounting frame. A spring 123 is sleeved on the part of the movable rod 122 located between the mounting frame and the annular clamp plate two. The two ends of the spring 123 are fixedly connected to the mounting frame and the annular clamp plate two, respectively.

[0066] The elastic clamp 12 increases the clamping force on the outer periphery of the utility pole, and together with the support rod 13, makes the pole more stable when fixed. The utility pole is installed inside the arc-shaped clamping plate 121. The compression of the spring 123 allows the multiple arc-shaped clamping plates 121 to fit more closely to the outside of the utility pole. The inside of the arc-shaped clamping plate 121 has anti-slip texture near the end of the utility pole to increase the friction between the arc-shaped clamping plate 121 and the outer wall of the utility pole.

[0067] Working principle: Place the entire device into the installation pit and place the bottom end of the screw 33 against the soil, or use a tool to clamp the screw 33 to restrict its rotation, and then rotate the sleeve 32 to allow the screw 33 to extend downwards and drill into the soil, temporarily stabilizing the device. Then observe whether the pointer 21 points to the center line of the indicator 22 under the action of natural gravity. If the position indicated by the pointer 21 and the indicator 22 deviate, it indicates that the base plate 11 is tilted. If tilting occurs, adjust the adjusting feet 30: Open the door 34, hold the handle and rotate the gear 41, which drives the meshing rack 44 and the lifting column 43 to move up and down along the fixed frame 42. The device is moved to adjust the height of the four corners of the base plate 11 according to the actual situation until the pointer 21 points to the center line of the indicator ruler 22 under the action of natural gravity. After the adjustment is completed, the electric push rod 511 is turned on, which drives the toothed plate 512 to approach the gear 41 until it meshes with it. The upper and lower ends of the toothed plate 512 are locked into the L-shaped limit block 513. Then, the sleeve 2 522 is rotated to drive the abutment plate 524 connected to the screw 2 523 to slide on the upper end face of the housing 31 until it approaches the clamping lifting column 43. The root of the utility pole is then passed through the elastic clamp 12, the fixing block 14 and the mounting hole of the base plate 11 in sequence and finally inserted into the soil. Finally, the root of the utility pole and the device are buried and fixed.

[0068] Example 2

[0069] The method for fixing the base of a utility pole, using the utility pole base fixing device described in Example 1, includes the following steps:

[0070] S1: Place this device into the installation pit;

[0071] S2: Observe whether the pointer 21 on the fixed block 14 points to the center line of the indicator ruler 22 under the action of natural gravity;

[0072] S3: Adjust the lifting assembly 40 inside the housing 31, and adjust the height of the four corners of the base plate 11 through the connecting plate 35 until the pointer 21 points to the center line of the indicator ruler 22 under the action of natural gravity.

[0073] S4: Fix the height of each adjusting leg 30 by locking part 1 51 and locking part 2 52;

[0074] S5: Pass the base of the utility pole through the mounting holes of the fixing block 14 and the base plate 11 in sequence and finally insert it into the soil;

[0075] S6: Secure the base of the utility pole and this device by burying it in soil.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
