Description

Technical Field

[0001] This utility model relates to the field of power engineering construction technology, and in particular to a pole straightening device for power engineering construction. Background Technology

[0002] Electrical engineering refers to engineering related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering that uses electricity as a power source and energy source in various fields. It can also be understood as power transmission and transformation expansion engineering. Utility poles are the bridges of electricity, allowing electricity to be transported to various places. Common types of utility poles include wooden poles and cement poles.

[0003] For example, a power pole straightening device for power engineering construction, as described in "CN216766954U", includes a first straightening plate and a second straightening plate detachably connected to the first straightening plate. Both the first and second straightening plates have arc-shaped grooves on their adjacent sides, forming a circular slot through which the power pole passes. The inner wall of the arc-shaped grooves is provided with an anti-slip layer. Mounting blocks are fixedly installed at the upper ends of the first and second straightening plates, and a supporting side rod is provided on the inner side of each mounting block. A straightening mechanism is provided at the top of the two supporting side rods, and a fastening mechanism is provided on the outer side of the straightening mechanism. This utility model has a reasonable structure, is easy to use, has good straightening and fixing effects, and is highly practical.

[0004] However, in the existing technology, during the construction and operation of power engineering, after the poles are erected or operated for a period of time, they are prone to axial deviation or bending due to the influence of unbalanced tension of the conductors, wind load, foundation settlement and transportation and installation deviations. The existing on-site correction generally adopts the method of setting jacks or temporary supports in the middle and lower sections of the poles to push them, so that the poles will deform in the opposite direction to straighten them.

[0005] Although the above-mentioned scheme is simple and low-cost, it has some problems in practical applications. For example, the pole is relatively long and the upper end bears the crossarm, insulator string and conductor. The center of gravity is high and the top is heavy. When only point support is provided in the middle and lower sections, it is difficult to effectively constrain the upper section. It is easy to shrink back, swing or even become unstable. In addition, the conductor tension and lateral disturbances such as gusts of wind will be superimposed on the correction process, causing additional lateral displacement in the upper section. It is difficult to dissipate energy and limit the movement in time by relying on single or few point support in the middle and lower sections, resulting in limited correction accuracy. Utility Model Content

[0006] In view of the aforementioned existing problems, this utility model is proposed.

[0007] The purpose of this invention is to solve the problem that in the existing technology, only correcting the lower section of the pole can easily cause the pole to become unstable.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] On one hand, this utility model provides a pole straightening device for power engineering construction, which includes a base, a cylinder and a first fastening ring. The cylinder is provided in multiple ways and its lower end is hinged to the base. The first fastening ring is used to be sleeved on the outer side of the lower section of the pole. The upper end of the cylinder is hinged to the outer wall of the first fastening ring. An extension seat is provided on the base. A first fixing ring is provided above the end of the extension seat away from the base. A connecting ring is sleeved on the outer side of the upper end of the pole. A second fixing ring is provided on the edge of the connecting ring. The first fixing ring and the second fixing ring are connected by a steel wire rope.

[0010] Furthermore, the connecting ring includes a main fastening ring and an outer auxiliary ring. The main fastening ring, the outer auxiliary ring, and the first fastening ring are installed in the same way, and each of them consists of two half-ring structures fixed together by bolts. When installing the first fastening ring onto the pole, the two half-rings on the first fastening ring are separated in advance, and the half-rings are respectively put on both sides of the pole and fixed at both ends of the half-rings with corresponding bolts. The installation of the main fastening ring onto the pole is set in the same way, while the outer auxiliary ring is fastened and sleeved on the outside of the main fastening ring.

[0011] Furthermore, the inner ring of the main fastening ring is provided with an anti-slip pad, and a limiting groove is formed at the center of the outer ring of the main fastening ring. The outer auxiliary ring is sleeved on the limiting groove by corresponding bolts. Two second fixing rings are provided and symmetrically arranged on both sides of the outer wall of the main fastening ring. The main fastening ring and the outer auxiliary ring are assembled in a perpendicular direction. By vertically sleeved on the outside of the main fastening ring, the firmness between the main fastening ring and the pole is increased. In addition, the assembly direction of the main fastening ring and the outer auxiliary ring is perpendicular. When the wire rope pulls the half ring of the main fastening ring, the outer auxiliary ring provides a tightening force on the main fastening ring to prevent the bolts on the main fastening ring from coming off and causing danger.

[0012] Furthermore, the base is arranged in a ring structure with an opening on one side, and the lower ends of the multiple cylinders are arranged in a ring at equal intervals above the base. The upper ends of the cylinders are hinged at equal intervals below the first fastening ring. By evenly distributing the multiple cylinders, the support for the pole is made more uniform.

[0013] Furthermore, ground spikes are provided below both the extension seat and the base, and a fixing frame is provided above the extension seat. The fixing frame is equipped with a rotating shaft and a motor. The rotating shaft is rotatably mounted on the extension seat and is driven to rotate by the motor. By driving the motor, the rotating shaft is rotated to tighten the wire rope, pull the pole to a vertical position, and work with the cylinder to keep it stable. The fixing frame is equipped with a wire rope anti-reverse device, through which the wire rope passes. This wire rope anti-reverse device is a common existing technology structure. Its principle is that when the rotating shaft rotates and winds the wire rope, the wire rope passes smoothly. Once there is a tendency to retract, the built-in eccentric or wedge block is tightened to bite the rope, forming a one-way anti-reverse.

[0014] Furthermore, a protective cover is provided above the fixing frame, and the motor and rotating shaft are installed inside the protective cover. The protective cover is used to protect the motor and rotating shaft and prevent pedestrians from touching them and causing injury when walking nearby.

[0015] Furthermore, the end of the rotating shaft away from the motor is hollow, and a side hole communicating with the inside of the rotating shaft is provided on the side wall of the rotating shaft. One end of the steel wire rope passes through the side hole into the inside of the rotating shaft and exits from the end face of the rotating shaft, extending to the outer wall of the rotating shaft. When the steel wire rope is wound on the rotating shaft, the end of the steel wire rope can be bound to the rotating shaft to fix the end and prevent it from falling off.

[0016] Furthermore, the first fixing ring is provided with rollers, and the steel wire rope is wound around the rollers. Through the rollers, when the rotating shaft rotates and pulls the steel wire rope to move and tighten, the movement is smoother.

[0017] The beneficial effects of this utility model are:

[0018] This invention involves pre-fixing the connecting ring to the upper end of the pole and positioning the second fixing ring on the opposite side of the pole's tilting direction. The base is then fitted onto the outside of the pole through a notch. The direction of the extension seat is adjusted so that it is on the same side as the second fixing ring. After adjusting the angle, one end of the steel wire rope is fixed to the second fixing ring, and the other end passes through the first fixing ring and is fixed to the rotating shaft. The first fastening ring is then securely fitted onto the lower section of the pole. The base and extension seat are fixed to the ground with ground nails. A motor is driven to rotate the rotating shaft, lifting and straightening the pole. During straightening, multiple cylinders work together to adjust the length until the pole is perpendicular to the ground. At this point, the base of the pole is supported by multiple cylinders, and the upper end is pulled by the steel wire rope, significantly reducing the pressure of the pole on the cylinders and making the support for the pole more stable.

The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Please see Figures 1-5 This utility model provides a technical solution: a pole straightening device for power engineering construction, including a base 1, cylinders 2, and a first fastening ring 3. Multiple cylinders 2 are provided, and their lower ends are hinged to the base 1. The first fastening ring 3 is used to fit around the lower outer side of the pole. The upper end of the cylinders 2 is hinged to the outer wall of the first fastening ring 3. The base 1 has an annular structure with an opening on one side. The lower ends of multiple cylinders 2 are arranged in a ring at equal intervals above the base 1, and the upper ends of the cylinders 2 are hinged at equal intervals below the first fastening ring 3. By evenly distributing the multiple cylinders 2, the support for the pole is more uniform. An extension seat 4 is provided on the base 1, and a first fixing ring 5 is provided above the end of the extension seat 4 away from the base 1. A connecting ring 6 is fitted around the upper outer side of the pole, and a second fixing ring 7 is provided on the edge of the connecting ring 6. The first fixing ring 5 and the... The second fixing rings 7 are connected by steel wire ropes 8. Ground nails 10 are provided below the extension seat 4 and the base 1. A fixing frame 111 is provided above the extension seat 4. The fixing frame 111 is equipped with a rotating shaft 112 and a motor 113. The rotating shaft 112 is rotatably mounted on the extension seat 4 and is driven to rotate by the motor 113. By driving the motor 113, the rotating shaft 112 is driven to rotate, which is used to tighten the steel wire rope 8 and pull the pole to a vertical position. It works with the cylinder 2 to keep it stable. A steel wire rope anti-reverse device is provided on the fixing frame 111. The steel wire rope 8 passes through the steel wire rope anti-reverse device. This steel wire rope anti-reverse device is a common existing technology structure. Its principle is that when the rotating shaft 112 rotates and winds the steel wire rope 8, the steel wire rope 8 passes smoothly. Once there is a tendency to retract, the built-in eccentric or wedge block is tightened to bite the rope, forming a one-way anti-reverse.

[0031] like Figures 1-5 As shown, the connecting ring 6 includes a main fastening ring 911 and an outer auxiliary ring 912. The main fastening ring 911, the outer auxiliary ring 912 and the first fastening ring 3 are installed in the same way, and all of them are fixed between two half-ring structures by bolts 913. When installing the first fastening ring 3 with the pole, the two half-rings on the first fastening ring 3 are separated in advance, and the half-rings are respectively put on the two sides of the pole, and the two ends of the half-rings are fixed with corresponding bolts 913. The installation of the main fastening ring 911 with the pole is set in the same way, while the outer auxiliary ring 912 is fastened to the outside of the main fastening ring 911.

[0032] like Figures 1-5As shown, the inner ring of the main fastening ring 911 is provided with an anti-slip pad 914, and a limiting groove 915 is opened at the center of the outer ring of the main fastening ring 911. The outer auxiliary ring 912 is sleeved on the limiting groove 915 by corresponding bolts 913. There are two second fixing rings 7, which are symmetrically arranged on both sides of the outer wall of the main fastening ring 911. The main fastening ring 911 and the outer auxiliary ring 912 are arranged perpendicularly. By vertically sleeved on the outside of the main fastening ring 911, the firmness between the main fastening ring 911 and the pole is increased. In addition, the assembly directions of the main fastening ring 911 and the outer auxiliary ring 912 are perpendicular. When the wire rope 8 pulls the half ring of the main fastening ring 911, the outer auxiliary ring 912 provides a tightening force on the main fastening ring 911 to prevent the bolts 913 on the main fastening ring 911 from coming off and causing danger.

[0033] like Figures 1-5 As shown, a protective cover 12 is provided above the fixing frame 111. The motor 113 and the rotating shaft 112 are installed inside the protective cover 12. The protective cover 12 is used to protect the motor 113 and the rotating shaft 112 to prevent pedestrians from touching them and causing injury when walking nearby.

[0034] like Figures 1-5 As shown, the end of the rotating shaft 112 away from the motor 113 is hollow. A side hole 13 is provided on the side wall of the rotating shaft 112, which communicates with the interior of the rotating shaft 112. One end of the wire rope 8 passes through the side hole 13 into the interior of the rotating shaft 112 and exits from the end face of the rotating shaft 112, extending to the outer wall of the rotating shaft 112. When the wire rope 8 is wound on the rotating shaft 112, the end of the wire rope 8 can be bound to the rotating shaft 112 to fix the end and prevent it from falling off.

[0035] like Figures 1-5 As shown, the first fixed ring 5 is provided with a roller 14, and the steel wire rope 8 is wound on the roller 14. Through the roller 14, when the rotating shaft 112 rotates and pulls the steel wire rope 8 to move and tighten, the movement is smoother.

[0036] Working principle: When installing the straightening device on the pole, the connecting ring 6 is pre-fitted and fixed to the upper end of the pole, and the second fixing ring 7 is positioned on the opposite side of the pole's tilting direction. Then, the base 1 is fitted onto the outside of the pole through the notch. The direction of the extension seat 4 is adjusted so that the extension seat 4 and the second fixing ring 7 are on the same side. After adjusting the angle, one end of the steel wire rope 8 is fixed to the second fixing ring 7, and the other end passes through the first fixing ring 5 and is fixed to the rotating shaft 112. The first fastening ring 3 is fastened to the lower middle section of the pole, and the base 1 and the extension seat 4 are fixed to the ground with ground nails 10. The motor 113 is driven to rotate the rotating shaft 112, pulling the pole up and straightening it. During the straightening process, multiple cylinders 2 work together to adjust the length until the pole is perpendicular to the ground. At this point, the base of the pole is supported by multiple cylinders 2, and the upper end is pulled by the steel wire rope 8, which greatly reduces the pressure of the pole on the cylinders 2, making the support of the pole more stable.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
