DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention provides a transmission line iron tower angle steel tower material replacement and protection device, comprising a fixed support 1 standing on the ground, a lifting assembly 2 adjusted according to the tower material position is arranged on the fixed support 1, the lifting assembly 2 comprises a guide frame 21 fixed to the fixed support 1 and perpendicular to the ground, a lifting platform 22 slidingly moving along the guide frame 21 is arranged on one side of the guide frame 21, a vertical frame 23 located on one side of the guide frame 21 is fixed on the lifting platform 22; the lifting platform 22 is fixedly welded to the vertical frame 23, and a pulley assembly a25 sliding along the other side of the guide frame 21 is arranged at the bottom of the lifting platform 22, a motor 24 is fixed on the lifting platform 22, an output end of the motor 24 passes through the vertical frame 23 and is installed with a gear b, and the gear b is meshed with a gear a on the guide frame 21; See also Figures 1 to 5 As shown, when replacing the tower angle steel tower material, the fixed bracket 1 is placed at a certain position according to the actual situation, and then the motor 24 is started, and the output end of the motor 24 drives the gear b to rotate. Since the gear a on one side of the guide frame 21 is meshed with the gear b, and because the guide frame 21 is fixedly connected to the fixed bracket 1, the motor 24 is fixedly installed on the lifting platform 22. Therefore, during the rotation of the output end of the motor 24, the motor 24 drives the lifting platform 22 to move along the guide frame 21, and at the same time, the lifting platform 22 drives the vertical frame 23 to move, and the vertical frame 23 drives the first protection mechanism 3 and the second protection mechanism 4 to move until they move to the position where the tower material needs to be replaced, and the first protection mechanism 4 is used to move the tower material. The structure 3 and the second protection mechanism 4 protect the tower body when replacing the angle steel tower material, so as to avoid the angle steel tower material being in a missing stage before the new angle steel tower material is installed after the angle steel tower material is removed, and the iron tower is in a state of stress change without protection, and the overall stress of the pole tower changes, resulting in the stress of some tower materials exceeding the design range, and there is a risk of tower material deformation and tower collapse accidents; in addition, the design of automatic movement of the vertical frame 23 can facilitate the replacement of angle steel tower materials in different positions, and improve the flexibility of replacement; at the same time, installation tools can be placed on the lifting platform 22, which is convenient for workers to take, and they do not have to bend down many times to pick up tools on the ground, saving manpower, improving work efficiency, and providing convenience for replacement work; The vertical frame 23 is provided with a first protection mechanism 3 connected to the tower body, and the first protection mechanism 3 includes a horizontal frame 32 fixedly connected to the vertical frame 23, and a telescopic frame 33 is telescopically slidable on one side of the horizontal frame 32, and a rotating shaft a34 is installed on the telescopic frame 33, and a rotating frame 31 that moves along the tower body is movable on the rotating shaft a34, and a telescopic oblique frame 36 for replacing the angle steel oblique material is rotated at one end of the rotating shaft a34, and one end of the telescopic oblique frame 36 is designed to be telescopic and connected to the angle steel horizontal material; while the vertical frame 23 moves along the lifting platform 22, the vertical frame 23 drives the rotating frame 31 to move through the horizontal frame 32 and the telescopic frame 33 At this time, the rotating frame 31 moves along the tower body, and the rotating frame 31 uses the rotating shaft a34 to rotate as the angle of the tower body changes during the movement of the rotating frame 31 along the tower body; both ends of the rotating frame 31 are equipped with pulley assemblies b35 that move along the tower body, and the interior of the cross frame 32 is provided with a slide groove for the sliding of the telescopic frame 33, and the telescopic frame 33 is provided with a scale a for measuring the length, and the telescopic frame 33 is equipped with an angle plate for measuring the inclination angle of the rotating frame 31, the rotating shaft a34 is connected to the rotating frame 31, and the telescopic frame 33 is fixedly connected to the rotating shaft a34, and the telescopic oblique frame 36 is rotatably arranged on the rotating shaft a34; See also Figures 3 to 8 As shown, during the movement of the vertical frame 23, the vertical frame 23 drives the rotating frame 31 to move through the horizontal frame 32 and the telescopic frame 33. Before the vertical frame 23 moves, the pulley assemblies b35 at both ends of the rotating frame 31 are placed close to one side of the tower body. When the vertical frame 23 moves, the rotating frame 31 moves along the tower body through the pulley assembly b35. Due to the inclined design of the tower body, when the rotating frame 31 fits the tower body, the rotating frame 31 rotates on the rotating shaft a34. Through the angle plate on the telescopic frame 33, during the movement of the rotating frame 31 along the tower body, it can be dynamically detected whether the inclination angle of the tower body meets the regulations. If during the movement of the rotating frame 31 fitting the tower body, the angle plate detects that the rotation amplitude of the rotating frame 31 on the telescopic frame 33 exceeds the error range, the staff is prompted to conduct further quality inspection on the tower body to improve the safety of the iron tower. After the rotating frame 31 moves to a certain position, before the angle steel diagonal material is replaced, the telescopic diagonal frame 36 is rotated on the rotating shaft a34 to make the telescopic diagonal frame 36 telescopic and one end of it connected to the angle steel crossbar. The length of the telescopic diagonal frame 36 can be measured, which is convenient for the staff to record data in order to analyze the cause of damage to the angle steel diagonal material; in addition, after the telescopic diagonal frame 36 and the angle steel crossbar are fixed, there is an angle between the telescopic diagonal frame 36 and the rotating frame 31. Through this angle, on the one hand, it can be convenient to play a positioning role when replacing the angle steel diagonal material. On the other hand, through this angle, it is compared with the angle between the angle steel diagonal material to be replaced and the tower body to see if they are consistent, which further assists the staff to record the data of the angle steel diagonal material to be replaced, so as to facilitate the subsequent quality analysis.

[0021] The vertical frame 23 is provided with an auxiliary rotating frame 31 for facilitating the replacement of the tower material. The second protective mechanism 4 includes a rotating shaft b42 rotating on the vertical frame 23. During the movement of the vertical frame 23, the rotating shaft b42 rotates through the meshing relationship between the gear a at one end and the gear a on one side of the guide frame 21. A rotating shaft c43 rotates on the horizontal frame 32. A rope 45 with one end connected to the rotating shaft b42 is wound around the rotating shaft c43. A gear c47 meshing with the gear b opened in the middle of the telescopic frame 33 is installed on the rotating shaft c43. The rotating shaft b42 rotates during the movement of the vertical frame 23. When the rotating shaft b42 rotates, the rope 45 is wound around the outside, and at the same time, the rope 45 pulls the rotating shaft c43 rotates, and the rotating shaft c43 drives the telescopic frame 33 to move by meshing with the gear b through the gear c47. At this time, the telescopic frame 33 drives the rotating frame 31 to move close to the tower body, so that the rotating frame 31 moves along the tower body and always fits the tower body; a vertical plate 44 is slidably arranged at one end of the rotating shaft c43, and a slot for engaging with the angle steel crossbar is provided on the vertical plate 44; a horizontal plate 41 is arranged on one side of the vertical frame 23, and the horizontal plate 41 is penetrated and connected with the rotating shaft b42 and the rotating shaft c43; a rectangular block 46 is fixed at one end of the rotating shaft c43, and the rectangular block 46 is engaged with the vertical plate 44, and the vertical plate 44 is penetrated and connected with the rotating shaft c43, and a rectangular slot for engaging with the rectangular block 46 is arranged at one end of the vertical plate 44; See also Figures 4 to 9 As shown, when the vertical frame 23 moves, the vertical frame 23 drives the rotating shaft b42 to move. Since the rotating shaft b42 is meshed with the gear a on one side of the guide frame 21 through the gear a at one end, the rotating shaft b42 rotates during the movement of the vertical frame 23, and the rotating shaft b42 winds the rope 45 around the outer side of the rotating shaft b42 when rotating. At the same time, the rope 45 is wound around the rotating shaft c43. During the process of the rope 45 winding around the rotating shaft b42, the rope 45 drives the rotating shaft c43 to rotate, and the rotating shaft c43 drives the gear c47 to rotate. Therefore, the rotating shaft c43 drives the telescopic frame 33 to move by meshing with the gear c47 and the gear b, thereby causing the telescopic frame 33 to drive the rotating frame 31 to move toward the tower body, thereby allowing the rotating frame 31 to continue to be in a close fit with the tower body while the rotating frame 31 moves upward; In addition, the size of the rotating shaft b42 can be adjusted according to actual conditions, so that when the rotating shaft b42 drives the rotating shaft c43 to rotate through the rope 45, the rotating shaft c43 drives the telescopic frame 33 to move through the gear c47, so that the telescopic frame 33 drives the rotating frame 31 to always fit with the tower body, so as to avoid the rotating frame 31 being separated from the tower body during the upward movement of the rotating frame 31, resulting in the rotating frame 31 being unable to maintain a stable connection with the tower body; In addition, after the telescopic oblique frame 36 is fixed to the angle steel crossbar, the vertical plate 44 is slid so that the slot on the vertical plate 44 is engaged with the angle steel crossbar, and at the same time, the vertical plate 44 is engaged with the rectangular block 46 through the rectangular slot, so that the rotating shaft c43 cannot rotate. On the one hand, the position of the rotating frame 31 is kept stable, and on the other hand, the rotating frame 31 is connected to the tower body, one end of the telescopic oblique frame 36 is connected to the rotating frame 31 and the other end is connected to the angle steel crossbar, one end of the vertical plate 44 is connected to the cross plate 41, and the other end is connected to the angle steel crossbar, thereby utilizing multi-angle protection measures to further stabilize the tower body and facilitate replacement of the angle steel oblique material.

[0022] Working principle: When replacing the tower angle steel material, the fixed bracket 1 is placed at a certain position according to the actual situation, and then the motor 24 is started. The output end of the motor 24 drives the gear b to rotate. Since the gear a on one side of the guide frame 21 is meshed with the gear b, and because the guide frame 21 is fixedly connected to the fixed bracket 1, the motor 24 is fixedly installed on the lifting platform 22. Therefore, during the rotation of the output end of the motor 24, the motor 24 drives the lifting platform 22 to move along the guide frame 21, and at the same time, the lifting platform 22 drives the vertical frame 23 to move. The vertical frame 23 drives the first protection mechanism 3 and the second protection mechanism 4 to move until they move to the position where the tower material needs to be replaced; during the movement of the vertical frame 23, the vertical frame 23 drives the rotating frame 31 to move through the horizontal frame 32 and the telescopic frame 33. Before the vertical frame 23 moves, the pulley assemblies b35 at both ends of the rotating frame 31 are placed on one side of the tower body. When the vertical frame 23 moves, the rotating frame 31 moves along the tower body through the pulley assembly b35. Due to the inclined design of the tower body, the rotating frame 31 is in close contact with the tower body.

[0023] After the rotating frame 31 moves to a certain position, before the diagonal steel diagonal material is replaced, the telescopic diagonal frame 36 is rotated on the rotating shaft a34, so that the telescopic diagonal frame 36 is telescoped and one end of the telescopic diagonal frame 36 is connected to the angle steel crossbar; while the vertical frame 23 moves, the vertical frame 23 drives the rotating shaft b42 to move. Since the rotating shaft b42 is meshed with the gear a at one end and the gear a on one side of the guide frame 21, the rotating shaft b42 rotates during the movement of the vertical frame 23, and the rotating shaft b42 rotates, and the rope 45 is wound around the outer side of the rotating shaft b42. At the same time, the rope 45 is wound around the rotating shaft c43, and the rope 45 is wound around the rotating shaft b42. During the winding process, the rope 45 drives the rotating shaft c43 to rotate, and the rotating shaft c43 drives the gear c47 to rotate. Therefore, the rotating shaft c43 drives the telescopic frame 33 to move by engaging the gear c47 with the gear b, thereby making the telescopic frame 33 drive the rotating frame 31 to move toward the tower body, thereby making the rotating frame 31 keep in contact with the tower body while moving upward; in addition, after the telescopic inclined frame 36 is fixed to the angle steel crossbar, the vertical plate 44 is slid so that the slot on the vertical plate 44 is engaged with the angle steel crossbar, and at the same time, the vertical plate 44 is engaged with the rectangular block 46 through the rectangular slot, thereby making the rotating shaft c43 unable to rotate.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
