Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to a transmission tower straightening and reinforcement device. Background Art

[0002] Transmission tower is a specially designed tower structure used to support and suspend high-voltage transmission lines. Its main function is to ensure the safe operation of power lines while maintaining a safe distance between the lines and the ground and other objects. The height of the transmission tower depends on the voltage level of the transmission line and the terrain requirements, and can range from tens of meters to hundreds of meters. The transmission tower is composed of a tower base and a tower body. The tower base is the supporting structure of the transmission tower, which is used to fix the tower on the ground or foundation; the tower body is the main structure of the transmission tower.

[0003] Due to some reasons, such as uneven foundation soil or improper foundation treatment, land landslide or collapse, earthquake, uneven load on both sides of the tower, extreme weather such as strong winds, external impact accidents such as vehicle collisions, etc., the tower base will move, causing the tower body to tilt in the vertical and / or horizontal direction.

[0004] In the case where the transmission tower tilts in the vertical direction, a Chinese patent document with authorization announcement number CN115075647B discloses a transmission tower correction device and a correction method, including a base plate horizontally arranged on the ground and a jacking assembly installed on the base plate; the jacking assembly includes a hydraulic cylinder, a support seat and a support rod, and one end of the support rod is horizontally fixed to the main material of the transmission tower during correction.

[0005] With regard to the above-mentioned related technologies, one end of the support rod is horizontally fixed to the main material of the transmission tower when correcting the deviation. During the straightening process, the main beam of the tower's main supporting leg and the force of the hydraulic cylinder are not in the same straight line, resulting in a force perpendicular to the main beam to twist the main beam. Due to the limited torsional resistance of the main beam, the main beam structure may be damaged, and in severe cases, the entire transmission tower may need to be rebuilt. Summary of the invention

[0006] In view of this, the present invention provides a transmission tower straightening and reinforcement device, aiming to solve the technical problem in the prior art that the torsional stress on the main beam of the tower body during the straightening process of the transmission tower may cause damage to the tower body.

[0008] By adopting the above technical scheme, the bottom and output end of the hydraulic cylinder are both ball joints, so that the inclination angle of the hydraulic cylinder gradually changes with the tower body straightening process, which is beneficial to reducing the angle between the direction of the output force of the output end of the hydraulic cylinder and the direction of the main beam of the tower body, thereby reducing the torsional stress on the main beam; through multiple first cables, the base can be fixed, which is beneficial to the stability of the base, and at the same time can reduce the demand for ground flatness during the installation process of the base, and improve the convenience of the straightening and reinforcement process; the pulley group can amplify the distance change, so that the second cable and the second clamping plate have an inclined downward force on the tower body, making the straightening process more stable, which is beneficial to maintaining the balance of the tower body during the straightening process, and at the same time can reduce the lifting force required by the main beam on the side of the tower body settlement, and then can also reduce the torsional stress on the main beam on the side of the tower body settlement, which is beneficial to reducing the probability of damage to the tower body; at the same time, the first clamping plate and the second clamping plate can enhance the torsional resistance of the force-bearing position of the main beam.

[0010] By adopting the above technical solution, the connection between the other three main beams of the tower body and the base is strengthened, so that the first cable can fix the base, improve the stability of the device, and improve the stability of the righting process.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0027] The following is combined with Figure 1 -Attached Figure 5 The present invention is described in further detail.

[0028] The embodiment of the present invention discloses a transmission tower straightening and reinforcement device. Figures 1 to 5 A transmission tower straightening and reinforcement device includes a base 1, a hydraulic cylinder 2, a first clamping plate 3, a second clamping plate 4, a plurality of first cables 5 and a second cable 6.

[0029] Reference Figure 1 and Figure 2 The base 1 is in the shape of a rectangular parallelepiped as a whole. The base 1 is placed on the side where the tower body 12 is lowered. The base 1 is placed on the outer edge of the tower body 12 to support the hydraulic cylinder 2 so that the hydraulic cylinder 2 can exert force on the main beam on the side where the tower body 12 is lowered.

[0030] Reference Figure 2 and Figure 3The side wall of the base 1 and the other three main beams of the tower body 12 are pulled together by three first cables 5 .

[0031] The three first cables 5 can fix the base 1, which is beneficial to the stability of the base 1. At the same time, it can reduce the requirement for ground flatness during the installation of the base 1 and improve the convenience of the straightening and reinforcement process.

[0032] Reference Figure 3 and Figure 4 The bottom of the hydraulic cylinder 2 is spherically hinged to the top surface of the base 1, and the hydraulic cylinder 2 is used to lift the tower body 12 and straighten the tower body 12. The first clamping plate 3 is connected to the main beam on the side where the tower body 12 is settled, and the output end of the hydraulic cylinder 2 is spherically hinged to the first clamping plate 3.

[0033] The bottom and output end of the hydraulic cylinder 2 are both ball joints, so that the inclination angle of the hydraulic cylinder 2 gradually changes with the straightening process of the tower body 12, which is beneficial to reducing the angle between the direction of the output force of the output end of the hydraulic cylinder 2 and the direction of the main beam of the tower body 12, thereby reducing the torsional stress on the main beam. The first clamping plate 3 can enhance the torsional resistance of the force-bearing position of the main beam.

[0034] Reference Figure 2 and Figure 5 , the second clamping plate 4 is connected to the main beam opposite to the main beam on the settlement side. The second clamping plate 4 is detachably connected to the second cable 6, and the second cable 6 is detachably connected to the top surface of the base 1 after passing through the first fixed pulley 7 fixed on the ground, the second fixed pulley 8 fixed on the top surface of the base 1, and the third fixed pulley 9 fixed on the first clamping plate 3 in sequence. The first fixed pulley 7 is placed on the side of the tower body 12 away from the base 1. The specific placement position of the first fixed pulley 7 needs to be calculated by professionals. The specific calculation method belongs to the technical content well known to those skilled in the art and will not be described in detail here.

[0035] The pulley block can magnify the distance change so that the second cable 6 and the second clamping plate 4 exert an inclined downward force on the tower body 12. The first clamping plate 3 and the second clamping plate 4 work together on the tower body 12 to make the straightening process more stable, which is beneficial to maintaining the balance of the tower body 12 during the straightening process. At the same time, it can reduce the lifting force required for the main beam on the side of the tower body 12 that has settled, and thus can also reduce the torsional stress on the main beam on the side of the tower body 12 that has settled, which is beneficial to reducing the probability of damage to the tower body 12. The second clamping plate 4 can enhance the torsional resistance of the force-bearing position of the main beam.

[0036] Reference Figure 3There are three first cables 5, two of which are connected between the side of the base 1 and the bottom of the main beam opposite to the main beam on the settlement side, and the two ends of another first cable 5 are respectively connected to the bottoms of two main beams adjacent to the main beam on the settlement side, and the lines connecting the two main beams adjacent to the main beam on the settlement side and the main beam on the settlement side form an isosceles triangle, and the middle parts of two of the first cables 5 are connected to another first cable 5.

[0037] The connection between the other three main beams of the tower body 12 and the base 1 is strengthened so that the first cable 5 can fix the base 1, thereby improving the stability of the device and the stability of the righting process.

[0038] Reference Figure 3 The end of the first cable 5 is fixed by a binding knot, and the first cables 5 are fixed to each other by a binding knot.

[0039] The binding knot is a commonly used connection method, which is beneficial to reducing the workload of workers during the construction process, can improve the convenience of the construction process, facilitate installation, and reduce the occurrence of accidental loosening of the first cable 5, thereby ensuring the stability of the construction process.

[0040] Reference Figure 5 The two ends of the second cable 6 are detachably connected in the form of nuts and screws.

[0041] The screw is fixedly connected to the end of the second cable 6, and the nut is installed at the installation position of the end of the second cable 6. The screw thread is inserted into the nut, which is a commonly used connection method. The flexibility of the lifting device facilitates the installation of the first clamping plate 3 and the second clamping plate 4 according to the settlement of the tower body 12, and then the second cable 6 is installed according to the installation condition of the first fixed pulley 7. It is easy to use and improves the convenience of the construction process.

[0042] Reference Figure 2 and Figure 4 The first clamping plate 3 and the second clamping plate 4 are both composed of two clamping plates 10 respectively attached to the inner and outer sides of the main beam.

[0043] The two clamping plates 10 cooperate with each other to facilitate the force to be transmitted to the first clamping plate 3 and the second clamping plate 4 and then act on the main beam, which can improve the torsional resistance of the main beam and improve the stability of the straightening process.

[0044] Reference Figure 4 The two clamping plates 10 are fixed by bolts and nuts.

[0045] One end of the bolt passes through the two clamps 10 and is threadedly connected to the nut. The bolt and the nut cooperate to limit the position of the two clamps 10 and the main beam, making them firmly connected and facilitating the application of force to the main beam through the clamps 10. This is a commonly used connection method, which is easy to install and disassemble, and improves the convenience of the construction process.

[0046] Reference Figure 4 The interface between the clamping plate 10 and the main beam is provided with anti-slip grooves.

[0047] Reference Figure 4 A connecting plate 11 is fixedly connected to the clamping plate 10 attached to the outside of the main beam, the hydraulic cylinder 2 and the third fixed pulley 9 are connected to one of the connecting plates 11, and the end of the second cable 6 is connected to the other connecting plate 11. It is convenient to install other structures, provide force points, and improve stability.

[0048] The implementation principle of a transmission tower straightening and reinforcement device according to an embodiment of the present invention is as follows: A base 1, a hydraulic cylinder 2 and a first clamping plate 3 are installed on one side of the tower body 12 where it is lowered, and three first cables 5 are installed.

[0049] The second clamping plate 4 and the first fixed pulley 7 are installed, and the second cable 6 is installed.

[0050] Start the hydraulic cylinder 2, and the output end of the hydraulic cylinder 2 exerts force on the first clamping plate 3 to lift the main beam on the side of the tower body 12 that has settled. As the main beam on the side of the tower body 12 that has settled is lifted, the first clamping plate 3 moves with the tower body 12, pulling the second cable 6 to move, so that the second cable 6 exerts force on the second clamping plate 4. The first clamping plate 3 and the second clamping plate 4 jointly exert force on the tower body 12 to straighten the tower body 12, and the tower base on the side of the tower body 12 that has settled is repaired and reinforced, and the tower body 12 and the tower base are re-fixed to complete the straightening and reinforcement.

[0051] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
