Description

Technical Field

[0001] This invention relates to the field of power equipment erection technology, specifically to a pole straightening device for power grid erection. Background Technology

[0002] During the construction of power grids, it is usually necessary to use erection poles fixed to the ground foundation to erect cables at a safe height. Commonly used erection poles include cement power poles. High-voltage transmission lines require the use of power towers to complete the erection.

[0003] During the construction of cement utility poles, it is necessary to erect the horizontal poles placed on the ground. However, due to the heavy weight of the utility poles, it is difficult to erect them manually. Currently, most of the time, a crane is used to lift the cement poles with straps attached, and then the poles are manually straightened and buried. However, the strapped poles are prone to swaying and shaking, and there is a risk of slipping, which can easily lead to construction accidents and is not very safe. Summary of the Invention

[0004] The purpose of this invention is to provide a pole straightening device for power grid erection, in order to solve the problems mentioned in the background art, such as the poles with ties being prone to swaying and falling, posing a risk of construction accidents and low safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A device for straightening a pole used in power grid erection includes an I-shaped base, a lifting mechanism, a clamping mechanism, and a fixing component. The lifting mechanism includes a lifting auxiliary component and a bearing. A limit groove is provided on the left side of the lifting auxiliary component. A drive motor is provided on the top of the lifting auxiliary component. The output end of the drive motor passes through the top of the lifting auxiliary component and is fixedly connected to a threaded rod through a coupling. The other end of the threaded rod is rotatably connected to the top of the I-shaped base through a bearing.

[0007] The present invention is further configured such that: the clamping mechanism includes a U-shaped block, a bolt, and a nut; the U-shaped block is symmetrically inserted with a round rod; one end of the round rod is fixedly connected to a circular stop block; the other end of the round rod is fixedly connected to a semi-circular component; and the two semi-circular components are fixedly connected by bolts and nuts.

[0008] By adopting the above technical solution, the clamping mechanism provides a more stable clamping effect on the erected pole, making it less prone to swaying and shaking, greatly reducing the risk of slippage, minimizing construction accidents, and ensuring high safety.

[0009] The present invention is further configured such that: the fixing component includes a fixing bolt, and the bottom end of the fixing bolt is provided with a sharp corner.

[0010] The above technical solution is used to create a sharp angle, which makes it easy to insert into the soil.

[0011] The present invention is further configured such that the bottom of the lifting auxiliary component is fixedly connected to the top of the I-shaped base.

[0012] Using the above technical solution, the lifting auxiliary component mainly plays a supporting role.

[0013] The present invention is further configured such that: the right side of the U-shaped block is fixedly connected to the left side of the lifting block, and the U-shaped block is movably connected to the outer wall of the round rod.

[0014] By adopting the above technical solution, the outer wall of the round rod is movably connected to the U-shaped block. Firstly, during the clamping process of the erection rod, it is convenient to place the two semi-circular parts on the outer wall of the erection rod for clamping. Secondly, during the process of the U-shaped block rising under the action of the lifting block, the erection rod can also rotate around the round rod under the influence of gravity, thereby achieving the purpose of straightening. Furthermore, with the cooperation of the I-shaped base, the foundation pit of the erection rod can be locked, so that after the erection rod is straightened, it can be accurately erected vertically in the foundation pit. After the erection rod is erected, the height of the rod can be quickly adjusted so that the erection rod is inserted into the foundation pit at a suitable depth.

[0015] The present invention is further configured such that the fixing bolt is threadedly connected to the I-shaped base.

[0016] By adopting the above technical solution, when the device is working, the lower end of the fixing bolt is inserted into the ground, and the threads on the fixing bolt contact the soil, which will enhance the stabilizing effect and make the device less prone to movement.

[0017] The present invention is further configured such that the drive motor is fixedly mounted on the top of the lifting auxiliary component via a motor frame.

[0018] Using the above technical solution, the drive motor and geared motor can rotate in both forward and reverse directions, thereby driving the threaded rod to rotate in both directions. Under the limiting action of the limiting groove, the lifting block can move up and down.

[0019] The present invention is further configured such that: a reinforcing rib is provided between the side of the lifting auxiliary component and the top of the I-shaped base.

[0020] Using the above technical solution, there are four reinforcing ribs, which are symmetrically arranged about the I-shaped base. The lifting accessories are fixedly connected to the I-shaped base by the reinforcing ribs, making the device more robust and stable.

[0021] The present invention is further configured such that: the bottom of the I-shaped base is provided with rollers.

[0022] The above technical solution facilitates the movement of the device via rollers.

[0023] This invention provides a device for straightening poles used in power grid construction. It has the following advantages:

[0024] (1) The present invention is movably connected to the outer wall of the round rod and the U-shaped block. Firstly, during the clamping process of the erecting rod, it is convenient to place the two semi-circular parts on the outer wall of the erecting rod for clamping. Secondly, during the process of the U-shaped block rising under the action of the lifting block, the erecting rod can also rotate around the round rod under the influence of gravity while rising. With the cooperation of the lifting mechanism and the clamping mechanism, not only is the purpose of straightening achieved, but the clamping effect is also more stable, and it is not easy to cause swaying or shaking, which greatly reduces the risk of slippage, reduces construction accidents, and has high safety.

[0025] (2) With the cooperation of the I-shaped base, the U-shaped block in the clamping mechanism can lock the foundation pit of the erecting pole, so that the erecting pole can be accurately erected vertically in the foundation pit after being straightened. After the erecting pole is erected, the height of the pole can be quickly adjusted so that the erecting pole is inserted into the foundation pit at a suitable depth.

[0026] (3) By setting an I-shaped base, the present invention can keep the center of gravity of the device in the middle position during the straightening process, without the need to use a counterweight box for counterweight, thus avoiding the tilting and collapse accident caused by the change of the center of gravity, and ensuring the normal and safe operation of the device.

[0027] (4) The present invention uses a reinforcing rib to fix the lifting accessory to the I-shaped base, making the device more robust and stable. Rollers are installed at the bottom of the I-shaped base to facilitate the movement of the device by the rollers. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figure 1-6 As shown, the present invention provides a technical solution: a pole straightening device for power grid erection, including an I-shaped base 1, a lifting mechanism 2, a clamping mechanism 3 and a fixing component 4. A reinforcing rib 6 is provided between the side of the lifting auxiliary component 21 and the top of the I-shaped base 1. There are four reinforcing ribs 6, which are symmetrically arranged about the I-shaped base 1. The lifting auxiliary component 21 and the I-shaped base 1 are fixedly connected with the reinforcing ribs 6, making the device more robust and stable. The bottom of the I-shaped base 1 is provided with rollers 5, which facilitates the movement of the device by means of the rollers 5.

[0038] The lifting mechanism 2 includes a lifting auxiliary component 21 and a bearing 26. The bottom of the lifting auxiliary component 21 is fixedly connected to the top of the I-shaped base 1. The lifting auxiliary component 21 mainly serves a supporting function. A limit groove 22 is provided on the left side of the lifting auxiliary component 21. A drive motor 23 is provided on the top of the lifting auxiliary component 21. The drive motor 23 is fixedly installed on the top of the lifting auxiliary component 21 through a motor frame. The drive motor is a reduction motor that can rotate forward and backward, thereby driving the threaded rod 24 to rotate forward and backward. Under the limiting action of the limit groove 22, the lifting block 25 moves up and down. The output end of the drive motor 23 passes through the top of the lifting auxiliary component 21 and is fixedly connected to the threaded rod 24 through a coupling. The other end of the threaded rod 24 is rotatably connected to the top of the I-shaped base 1 through the bearing 26.

[0039] The clamping mechanism 3 includes a U-shaped block 31, bolts 35, and nuts 36. The right side of the U-shaped block 31 is fixedly connected to the left side of the lifting block 25, and the U-shaped block 31 is movably connected to the outer wall of the round rod 32. This movable connection between the outer wall of the round rod 32 and the U-shaped block 31 facilitates the placement of the two semi-circular parts 34 on the outer wall of the erecting rod for clamping during the clamping process. Furthermore, as the U-shaped block 31 rises under the influence of the lifting block 25, the erecting rod, while rising, can also rotate around the round rod 32 under the influence of gravity, thus achieving the purpose of straightening. In conjunction with the I-shaped base 1, it can also support the erecting rod. The pole is locked in the foundation pit, so that the pole can be accurately and vertically erected in the pit after being straightened. After the pole is erected, the height of the pole can be quickly adjusted so that the pole is inserted into the appropriate depth in the foundation pit. U-shaped blocks 31 are symmetrically inserted with round poles 32. One end of the round pole 32 is fixedly connected to a round stop block 33, and the other end of the round pole 32 is fixedly connected to a semi-circular piece 34. The two semi-circular pieces 34 are fixedly connected by bolts 35 and nuts 36. The clamping mechanism 3 clamps the pole more stably, making it less prone to swaying and shaking, greatly reducing the risk of slippage, reducing construction accidents, and ensuring high safety.

[0040] The fixing component 4 includes a fixing bolt 41, which is threadedly connected to the I-shaped base 1. When the device is working, the lower end of the fixing bolt 41 is inserted into the ground. The threads on the fixing bolt 41 come into contact with the soil, which will enhance the stabilizing effect and make the device less prone to movement. The bottom end of the fixing bolt 41 is provided with a pointed corner 42, which makes it easy to insert into the soil.

[0041] Working principle: The outer wall of the round rod 32 is movably connected to the U-shaped block 31. First, during the clamping process of the erecting rod, it is convenient to place the two semi-circular parts 34 on the outer wall of the erecting rod for clamping. Second, during the process of the U-shaped block 31 rising under the action of the lifting block 25, the erecting rod can also rotate around the round rod 32 under the influence of gravity while rising. With the cooperation of the lifting mechanism 2 and the clamping mechanism 3, not only is the purpose of straightening achieved, but the clamping effect is also more stable, and it is not easy to sway or shake, which greatly reduces the risk of slippage, reduces construction accidents, and ensures high safety.

[0042] With the cooperation of the I-shaped base 1, the U-shaped block 31 in the clamping mechanism 3 can lock the foundation pit of the erecting pole, so that after the erecting pole is straightened, it can be accurately erected vertically in the foundation pit. After the erecting pole is erected, the height of the pole can be quickly adjusted so that the erecting pole is inserted into the foundation pit at a suitable depth.

[0043] By setting the I-shaped base 1, the center of gravity of the device can always be kept in the middle position during the straightening process, without the need to use a counterweight box for counterweight, thus avoiding the tilting and collapse accident caused by the change of the center of gravity, and ensuring the normal and safe operation of the device.

[0044] Four reinforcing ribs 6 are symmetrically arranged about the I-shaped base 1. The lifting auxiliary component 21 is fixedly connected to the reinforcing ribs 6 with the I-shaped base 1, making the device more robust and stable. Rollers 5 are installed at the bottom of the I-shaped base 1 to facilitate the movement of the device via the rollers 5.
