[0002] Transmission line towers are the main equipment for laying lines in power grid construction. They are space truss structures. The entire tower body is composed of a main material as an overall support and a diagonal tie rod for pulling and fixing the main material. However, since the main material of the current transmission line tower is mainly made of a single equilateral angle steel or a combined angle steel, the main material is prone to deformation under the action of external forces during long-term use. In order to ensure the safety of the use of the transmission line tower, the deformed main material needs to be replaced in time. However, there is currently no special device in the industry that can be used for the main material replacement of the transmission line tower. When replacing the main material, it is necessary to cut off the power supply to the transmission line and manually pull and reset the transmission line tower. Since manual traction and reset cannot be performed accurately and effectively, the tower as a whole is prone to deformation or tilt during and after the main material replacement, resulting in poor safety in the use of the tower after the main material is replaced, and its service life will also be shortened.

[0003] To this end, we need to develop a special device for replacing the main materials of the transmission line tower that can ensure that the tower as a whole will not tilt or deform during and after the main material replacement, so as to meet the development needs of this industry.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0025] Example

[0026] like Figure 1 and Figure 2As shown, the main material replacement device of the tower body of the power transmission line of the utility model comprises a main support frame 1, an adjustment bracket 5, an adjustment device 3, and a main material clamp 7. Specifically, the main support frame 1 is a steel structure as a whole, which is composed of a left arm 1-1 and a right arm 1-3 and a plurality of cross arms 1-2. The plurality of cross arms 1-2 are used to connect the left arm 1-1 and the right arm 1-3. The plurality of cross arms 1-2 are evenly distributed between the left arm 1-1 and the right arm 1-3. During installation, one end of the cross arm 1-2 is connected to the left arm 1-1 by welding, and the other end is connected to the right arm 1-3 by welding. Among them, the left arm 1-1 and the right arm 1-3 are both hollow steel pipes. During specific production, the left arm 1-1 and the right arm 1-3 can be realized by hollow steel pipes with a diameter of 6 to 10 cm and a wall thickness of 1 to 2 cm.

[0027] Among them, the adjustment bracket 5 is movably arranged at the top of the main support frame 1, that is, the adjustment bracket 5 is respectively plugged with the left support arm 1-1 and the right support arm 1-3, and the adjustment bracket 5 can slide up and down along the inner tube wall of the left support arm 1-1 and the right support arm 1-3. The length of the main support frame 1 and the adjustment bracket 5 needs to be set according to actual needs. The length of the main support frame 1 can be set according to the length of each main material of the iron tower in the prior art. When setting, the length of the main support frame 1 can be slightly less than or greater than the length of the main material. There is no specific setting requirement for the length of the adjustment bracket 5. The adjustment device 3 is also arranged at the top of the main support frame 1, and the adjustment bracket 5 is connected to the adjustment device 3. The adjustment device 3 is used to adjust the height of the adjustment bracket 5, that is, the adjustment bracket 5 can move up and down under the action of the adjustment device 3. In order to facilitate the installation and fixation of the adjustment device 3, a leveling support platform 4 is arranged at the top of the main support frame 1. The leveling support platform 4 is horizontally fixed at the top of the main support frame 1, and the thickness of the leveling support platform 4 is 1.5 to 2.5 cm. During installation, the leveling support platform 4 and the main support frame 1 are preferably fixed by welding, and the adjusting device 3 is vertically fixed on the leveling support platform 4. The adjusting device 3 and the leveling support platform 4 are fixed by bolts.

[0028] When used specifically, the adjusting device 3 in this embodiment is a jack or a hydraulic rod, and the adjusting bracket 5 is connected to the telescopic arm of the jack or the hydraulic rod through a top plate 6. The top plate 6 is horizontally fixed on the adjusting bracket 5, and its thickness is 1.5 to 2.5 cm. When installed, the top plate 6 is fixed to the adjusting bracket 5 by welding. In this embodiment, the adjusting device 3 is preferably implemented by a single-section 50-ton jack, so as to better level the iron tower.

[0029] like Figure 1 As shown, the main material hoop 7 is arranged on the adjustment bracket 5. During installation, the arm of the main material hoop 7 is fixed on the adjustment bracket 5 by welding. Figure 5As shown, it is a conventional clamp in the prior art that is composed of two pieces of hinged iron, and the two pieces of iron are locked by bolts after clamping, so this specification does not elaborate on the specific structure of the main material clamp 7. When in use, the main material clamp 7 is clamped on the main material above the main material to be replaced, and the main material clamp 7 is locked and fixed by bolts after clamping.

[0030] like Figure 1 As shown, in order to effectively fix the main support frame 1 and to reinforce the iron tower as a whole when replacing the main material, to prevent the iron tower from deforming when replacing the main material, a plurality of main support frame positioning devices 2 are arranged on the main support frame 1. The plurality of main support frame positioning devices 2 are evenly distributed on the main support frame 1, that is, evenly distributed on the left arm 1-1 and the right arm 1-3 of the main support frame 1.

[0031] Among them, Figure 1 As shown, the main support frame positioning device 2 includes a hinge seat 2-1, a positioning arm 2-2, and a positioning hoop 2-3. Specifically, the hinge seat 2-1 is a conventional hinge head in the prior art. When installed, the hinge seat 2-1 is fixed to the left arm 1-1 and the right arm 1-3 of the main support frame 1 by bolts or welding. The positioning arm 2-2 is movably arranged on the hinge seat 2-1, that is, the positioning arm 2-2 is installed on the hinge seat 2-1 by a cross pin, so that the positioning arm 2-2 can swing up and down. At the same time, the positioning arm 2-2 can also swing horizontally under the action of the hinge seat 2-1. The number of positioning arms 2-2 is more than one, and the number of positioning arms 2-2 is set according to actual needs. In actual production, the length of the positioning arm 2-2 can be set with reference to the overall span of the conventional iron tower in the prior art. When setting, it is necessary to consider the different spans of the iron towers at different heights, that is, the length of the positioning arm 2-2 can be set accordingly according to the spans of the iron towers at different heights.

[0032] like Figure 1 As shown, the positioning hoop 2-3 is arranged on the positioning support arm 2-2. During installation, the positioning hoop 2-3 is fixed to the movable end of the positioning support arm 2-2 by welding. The structure of the positioning hoop 2-3 is the same as that of the main material hoop 7. Figure 5 As shown, it is a conventional clamp in the prior art composed of two pieces of hinged iron, and the two pieces of iron are locked by bolts after clamping, so the specific structure of the positioning clamp 2-3 is not described in detail in this specification. When in use, the positioning clamp 2-3 is clamped on the main material adjacent to the main material to be replaced, and after clamping, the positioning clamp 2-3 is locked and fixed by bolts, so that the positioning support arm 2-2 is in a tight state.

[0033] In order to be able to pull and fix the main support frame 1 well, and to facilitate the lifting and pulling of the replacement main material, so as to improve the stability and practicality of the entire device, at least one hand-operated hoist 8 is also arranged on the main support frame 1. The hand-operated hoist 8 is a conventional hand-operated hoist in the prior art, so this specification does not give a detailed description of its structure. During installation, the number of hand-operated hoists 8 can be set as needed. In this embodiment, the number of hand-operated hoists 8 is preferably set to one, and it is fixed to the left arm 1-1 or the right arm 1-3 of the main support frame 1 by bolts.

[0034] In order to ensure that the installation of the main support frame 1 is more convenient and stable, a reversible fixed bottom plate 9 is respectively provided at the lower end of the left support arm 1-1 and the right support arm 1-3 of the main support frame 1. During installation, the fixed bottom plate 9 is installed in the pre-set clamping grooves at the lower ends of the left support arm 1-1 and the right support arm 1-3 through the cross pin screw, so that the fixed bottom plate 9 can be flipped forward and backward. At the same time, if Figure 3 As shown, a plurality of fixing through holes are provided on the fixing base plate 9 to facilitate the fixing and installation of the fixing base plate 9. That is, during installation, the fixing base plate 9 is fixed to the installation surface of the iron tower or the fixing seat of the iron tower by expansion bolts.

[0035] In addition, in order to facilitate the docking of two tower main material replacement devices with power transmission lines, so as to facilitate the replacement of more than one section of main material, two docking plates 10 are set at the top of the adjustment bracket 5. During installation, the two docking plates 10 are symmetrically arranged at the top of the adjustment bracket 5, and the docking plates 10 are fixed to the top of the adjustment bracket 5 by welding, so that the docking plates 10 and the adjustment bracket 5 are fixed as one. At the same time, if Figure 4 As shown, holes matching the fixed through holes of the fixed bottom plate 9 are provided on the docking plate 10, that is, when two tower main material replacement devices with power transmission lines are docked, the docking plate 10 is docked with the fixed bottom plate 9, and after docking, the two are fixedly connected by bolts.

[0036] When in use, the fixed bottom plate 9 at the lower end of the main support frame 1 is fixed on the installation surface of the main material of the iron tower that needs to be replaced. The installation surface refers to the installation base or concrete floor of the iron tower. When the main support frame 1 is fixed, the main support frame 1 can be tilted according to the oblique direction of the iron tower by adjusting the fixed bottom plate 9, so that the support of the main support frame 1 is more stable. After the main support frame 1 is fixed, the main material clamp 7 at the upper end of the adjustment bracket 1 is fixed on the main material above the main material of the iron tower that needs to be replaced. After the main support frame 1 is fixed, its adjustment bracket 5 is in a fixed state at this time, and the adjustment bracket 5 will not slide up and down, because in the initial state, the adjustment device 3 is in a contracted and stationary state. At this time, the adjustment device 3 is equivalent to a fixed connection between the adjustment bracket 7 and the main support frame 1, so that the adjustment bracket 5 and the main support frame 1 form a support rod with a fixed length. After the main material clamp is fixed to the main material above the main material of the iron tower that needs to be replaced, the adjustment bracket and the main support frame together become the "temporary main material" of the iron tower, providing sufficient support for the iron tower.

[0037] After completing the fixed installation of the main support frame 1 and the adjustment bracket 5, use a level meter to determine whether the main material of the tower that needs to be replaced causes the tower to tilt. If so, adjust the height of the adjustment bracket 5 through the adjustment device 3 to keep the tower as a whole horizontal, and then proceed to the next step of installation; if not, proceed to the next step of installation.

[0038] The main support frame positioning device 2 on the main support frame 1 is fixed on two adjacent main materials of the iron tower main material that needs to be replaced, and each main support frame positioning device 2 is in a taut state, so that a multi-connection and multi-fixing point is formed between the main support frame 1 and the iron tower, so as to prevent the iron tower from being deformed when the main material is replaced, thereby realizing the overall fixation of the iron tower. Among them, when the main support frame positioning device 2 is fixed, by adjusting the inclination of the positioning arm 2-2 of the main support frame positioning device 2, each positioning arm 2-2 of each main support frame positioning device 2 will exert a traction force on the main support frame 1, so that the iron tower can be pulled and positioned in multiple directions. After all the main support frame positioning devices 2 are fixed and installed, the traction hook of the hand hoist 8 is fixed on the iron tower main material relative to the iron tower main material that needs to be replaced, so that the hand hoist 8 forms traction on the main support frame 1, and the iron tower main material that needs to be replaced can be removed and replaced. When replacing the main material, the hand hoist 8 can also be used as a hoisting device for the main material to facilitate the installation of the main material. After the main material is replaced, the main material replacement device of the tower body with power on the power transmission line is removed from the tower to complete the replacement of the main material of the tower.

[0039] In addition, if it is necessary to replace two or the middle main materials on the same side of the iron tower, two of the utility model's live tower main material replacement devices are needed. When used, one of the fixed bottom plates is fixed to the other's docking plate to achieve fixed support for replacing the two or the middle main materials. That is, the number and use of the utility model need to be adjusted accordingly according to actual conditions.

[0040] As described above, the utility model can be well implemented.
