[0002] Overhead line towers are an indispensable key infrastructure for power transmission and distribution networks. Their core function is to support overhead conductors and ground wires and ensure that they maintain sufficient safe distances from the ground, crossings, and other engineering facilities.

[0003] Currently, when assembling overhead line towers, the tower components are usually lifted using a suspended gantry, and then the construction workers connect the tower components. However, the gantry is initially placed flat on the ground, and it needs to be erected first. This is usually achieved by applying traction force to the upper end of the gantry. After the gantry is erected, its verticality needs to be measured. Otherwise, the gantry may sway during the initial lifting, requiring constant measurement and adjustment, which reduces construction efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for assembling overhead line towers, which can reduce the number of times the pole is measured during the pole erection process and improve construction efficiency.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described in detail below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0018] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium; it can be the communication inside two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0019] Reference Figures 1 to 2As shown, an auxiliary device for assembling overhead line towers includes four positioning bases 1, arranged around the center point of the construction area, which is the tower assembly location. A strip-shaped positioning element 2, such as a long strip plate, is connected between adjacent positioning bases 1, but it needs to have high load-bearing strength. The strip-shaped positioning element 2 and the positioning bases 1 form a U-shaped base frame, which surrounds the construction area. A center positioning pad 3 is placed at the center of the construction area, and the bottom end of the pole is connected to the center positioning pad 3. Initially, the pole is placed flat on the ground, and the two strip-shaped positioning elements 2... The length direction is perpendicular to the mast. One vertical strip-shaped positioning component 2 is located below the mast, while the length direction of two strip-shaped positioning components 2 is parallel to the mast. The two parallel strip-shaped positioning components 2 are located on both sides of the mast, so that the two parallel strip-shaped positioning components 2 are symmetrically arranged with the mast as the center line. A lifting frame is set on the base frame. After the lifting frame is connected to the flat mast by a pull line, the mast is flipped by controlling the movement of the lifting frame, changing the mast from a flat state to a vertical state. At this time, the central positioning pad 3 supports the mast. Then the tower legs are assembled in the construction area. The tower body can be assembled using the mast.

[0020] See Figures 1 to 4 As shown, the aforementioned center positioning pad 3 is connected to each strip positioning piece 2 on the base frame via the horizontal extension arm 4, thereby keeping the center positioning pad 3 in a fixed position. After the gantry is suspended and lifted, the center positioning pad 3 will no longer have a function. Therefore, the horizontal extension arm 4 and the strip positioning piece 2 are detachably connected, and the horizontal extension arm 4 and the center positioning pad 3 are also detachably connected. Through the detachable mechanism, the horizontal extension arm 4 and the center positioning pad 3 can be removed to avoid affecting the assembly of the tower body. Specifically, the strip-shaped positioning component 2 is provided with an end mating groove, which can be used to assemble the outer end of the flat extension arm 4 into the end mating groove, and then the two are connected by bolts. The inner end of the flat extension arm 4 is connected to the center positioning pad 3 by a pin. For example, a side protrusion 5 is provided on the side surface of the center positioning pad 3, and a slot 6 is provided on the side surface of the side protrusion 5. The inner end of the flat extension arm 4 is provided with a pin hole, and the side protrusion 5 is provided with an insertion hole. In order to enable the pin hole and the insertion hole to be quickly aligned, a baffle 7 is fixed on the flat extension arm 4. When the baffle 7 abuts against the side surface of the side protrusion 5, the pin hole and the insertion hole are aligned. Then the pin is inserted from the insertion hole, and the flat extension arm 4 and the center positioning pad 3 are connected by the pin. When disassembling, it is only necessary to pull out the pin and then apply a force away from the center positioning pad 3 to the flat extension arm 4 to quickly separate the flat extension arm 4 from the center positioning pad 3.

[0021] Only when the holding pole is in the suspended state, the center positioning pad 3 can be removed, the holding pole is connected with the center positioning pad 3, and the holding pole can be separated from the center positioning pad 3 when the holding pole is in the vertical state, at this time the holding pole can be moved upward, but it should be noted that the bottom end of the holding pole is connected with the supporting seat 8, and the connection between the holding pole and the center positioning pad 3 is actually the connection between the supporting seat 8 at the bottom end of the holding pole and the center positioning pad 3; Specifically, referring to Figures 5 to 6 As shown in the drawings, the supporting seat 8 comprises an end abutting part, an intermediate supporting and lifting part and a limiting part, which are arranged in sequence from top to bottom, wherein the end abutting part is used for connecting the lower end of the holding pole, the end abutting part is an upper boss 9, a planar abutting plate 10 is fixed at the upper end of the upper boss 9, a recessed groove 11 is arranged on the upper surface of the planar abutting plate 10, the lower end of the holding pole can be fitted in the recessed groove 11, and a threaded hole is arranged on the planar abutting plate 10 and communicates with the recessed groove 11, so that the planar plate can be connected with the lower end of the holding pole by a bolt; The intermediate supporting and lifting part comprises a disc 32 body 12, which is fixed at the lower end of the upper boss 9, at least four lateral arms 13 are arranged on the circumferential surface of the disc 32 body 12, the distal end of the lateral arm 13 is provided with an opening, a lifting connector is connected through the opening, the lifting connector is connected with the lateral arm 13 through a short shaft, so that the lifting connector can be relatively turned with the lateral arm 13, when the holding pole is lifted upward, the lifting line needs to be connected with the lifting connector (a pulley is arranged on the lifting connector), because the lifting connector is connected with the lateral arm 13 through the shaft, so that as the holding pole is gradually moved upward, the angle between the lifting connector and the lateral arm 13 changes gradually, so that the holding pole can be smoothly moved upward; The limiting part comprises a lower boss 14, which is fixed on the lower surface of the disc 32 body 12, a positioning shaft 15 and a track moving shaft 16 are arranged on the side surface of the lower boss 14, when the supporting seat 8 is in the vertical state, the track moving shaft 16 is located directly above the positioning shaft 15, at this time the track moving shaft 16 and the positioning shaft 15 are located in the same vertical plane.

[0022] A limiting table 17 is arranged on the upper surface of the center positioning pad 3, a limiting groove is arranged on the limiting table 17, the limiting groove extends downward from the top surface of the limiting table 17 and penetrates the side surface of the limiting table 17, two vertically extending track grooves are arranged on the inner wall of the limiting groove, the two track grooves are respectively an outer track groove 18 and an inner track groove 19, and an arc-shaped displacement groove 20 is connected between the two track grooves, when the supporting seat 8 is connected with the lower end of the holding pole and the holding pole is in the horizontal state, the holding pole is moved downward, in this process, the positioning shaft 15 and the track moving shaft 16 can enter the corresponding track groove, at this time the positioning shaft 15 and the track moving shaft 16 are located in the same horizontal plane; After the holding pole is connected with the lifting frame, the upper part of the holding pole is subjected to the force of the lifting frame, at this time the positioning shaft 15 on the supporting seat 8 abuts against the bottom of the inner track groove 19, then the holding pole starts to move around the positioning shaft 15, in this process the track moving shaft 16 enters the displacement groove 20 from the outer track groove 18, and with the gradual movement of the holding pole, the track moving shaft 16 can enter the inner track groove 19, that is, the positioning shaft 15 and the track moving shaft 16 are in the same track groove, at this time the holding pole is in the vertical state, after the upward force is applied to the supporting seat 8, the positioning shaft 15 and the track moving shaft 16 can be moved out of the inner track groove 19 at the same time, so as to realize the lifting of the holding pole. Since the holding pole is in the vertical state when the holding pole is lifted, the initial state of the upward movement of the holding pole is relatively stable, and the shaking of the holding pole is avoided. The positioning shaft 15, the outer track groove 18, the inner track groove 19 and the track moving shaft 16 form a limiting structure.

[0023] Referring to Figure 1 , Figure 7 and Figure 8 , one state of the lifting frame includes a herringbone-shaped frame body, and the other state is a door-shaped frame. The reference seat 21 is hingedly connected to the bottom end of the lifting frame. The reference seat 21 is slidably connected with the strip-shaped positioning member 2 on the bottom frame. For example, the slide rail 22 is arranged on the strip-shaped positioning member 2 and extends along the length direction of the strip-shaped positioning member 2. The bottom surface of the reference seat 21 is provided with a matching groove. The reference seat 21 is connected with the slide rail 22 through the matching groove, so that the reference seat 21 can slide along the length direction of the strip-shaped positioning member 2. The locking member is arranged on the reference seat 21. After the locking member cooperates with the slide rail 22, the position of the reference seat 21 is locked. The locking member can be a screw rod. The screw rod is screwed with the reference seat 21. When the screw rod is screwed, the lower end of the screw rod enters the matching groove. When the lower end of the screw rod abuts against the slide rail 22, the locking of the reference seat 21 is realized. The number of locking members can be adaptively adjusted according to the length of the lifting frame and the holding pole.

[0024] The upper end of the lifting frame is fixed with the traction seat 23. The traction seat 23 can be connected with the holding pole through the lifting line. Before the traction seat 23 is connected with the holding pole, the position of the sliding seat needs to be adjusted, so that the sliding seat is aligned with the center positioning pad 3. Then the sliding seat is positioned through the locking member. Then the lifting line connected with the traction seat 23 is connected with the middle upper part of the holding pole. Then the traction seat 23 is connected with the traction system. When the traction system works, the traction force can be applied to the traction seat 23, so as to drive the lifting frame to move, and finally realize the movement of the holding pole.

[0025] In the process of changing the derrick from the flat state to the vertical state, the derrick needs to swing around the positioning shaft 15, and through the setting of the track moving shaft 16, although the maximum swing angle of the derrick can be limited, in fact, when the derrick is adjusted, it is also easy to cause the hard collision between the track moving shaft 16 and the limiting table 17, thereby causing the deformation of the track moving shaft 16, and the root cause of this situation is that the derrick is over-controlled.

[0026] Referring to Figures 3 to 6 To avoid the above situation, the calibration pipe 24 is arranged on the limiting table 17, the calibration pipe 24 extends horizontally, the calibration pipe 24 is a pipe body, a horizontal extension channel is arranged on the limiting table 17, the horizontal extension channel is located on the extension line of the calibration pipe, one end of the horizontal extension channel is an outer end, the outer end is connected with the port of the calibration pipe 24, the other end of the horizontal extension channel is an inner end, the inner end is communicated with the inner track groove 19, the positioning shaft 15 is located in the track groove, the calibration rod 25 is connected to the limiting table 17, the inner end of the calibration rod 25 is close to the inner end of the horizontal extension channel, the outer end of the calibration rod 25 is located in the calibration pipe 24, the compression return spring is arranged in the calibration pipe 24, the compression return spring is connected with the calibration rod 25, initially, the inner end of the calibration rod 25 extends out of the horizontal extension channel, that is, at this time, the inner end of the calibration rod 25 is located directly above the positioning shaft 15, when the derrick is turned over to the vertical state, the force will be applied to the calibration rod 25, so that the calibration rod 25 moves outward; The vertical short pipe 26 is connected with the calibration pipe 24, the display rod (not shown in the figure) is inserted in the vertical short pipe 26, the display rod is a cylindrical rod body, the display rod can move vertically in the vertical short pipe 26, the through hole is arranged on the calibration rod 25, when the track moving shaft 16 is located directly above the positioning shaft 15, the through hole is aligned with the vertical short pipe 26, that is, at this time, the through hole is located on the extension line of the vertical short pipe 26, at this time, the lower part of the display rod will enter the through hole under the action of its own gravity, the hanging disc is fixed at the top end of the display rod, at this time, the hanging disc is pressed on the top end of the vertical short pipe 26, and there is no gap between the two, so that the position relationship between the hanging disc and the vertical short pipe 26 can be directly known to know whether the derrick is in the vertical state, so as to avoid excessive force, the calibration pipe 24, the horizontal extension channel, the calibration rod 25, the vertical short pipe 26 and the display rod and other components form a display assembly, through the display assembly, the state of the derrick can be accurately and directly known.

[0027] In the technical solution, referring to Figure 1 , Figure 7 and Figure 8As shown, the lifting frame is composed of two straight booms joined together. Each straight boom includes a bottom boom 27 and an upper boom 28. The bottom boom 27 and the upper boom 28 are hinged together. The bottom boom 27 is hinged to the slide block, so that the bottom boom 27 can be flipped and swung in the X direction, while the upper boom 28 can be flipped and swung in the Y direction. Specifically, the upper end of the bottom boom 27 is fixed with an extension plate 29, which has a round hole. The lower end of the upper boom 28 has a flat opening, and the extension plate 29 is located inside the flat opening. The upper boom 28 is connected to the extension plate 29 through a short shaft, allowing the upper boom 28 to swing around the short shaft. A locking hole is provided on the upper boom 28. When the upper ends of the two straight booms are connected through the traction seat 23, the locking hole is misaligned with the round hole on the extension plate 29. At this time, the two straight booms form a lifting frame, which is used to erect the boom.

[0028] After completing the erection of the boom, the traction seat 23 can be separated from the two straight booms, and then the straight booms can be made to be straight, so that the locking hole on the upper boom 28 is aligned with the round hole on the extension plate 29. Then, the bolt assembly is passed through the round hole and the locking hole, so that the upper boom 28 is finally located on the extension line of the bottom boom 27. At this time, the straight boom can be flipped and swung in the X direction. At this time, the two straight booms are parallel to each other. A pressure guide arm can be connected between the tops of the two straight booms. After the mast is erected, the straight booms can be moved away from the mast by the sliding block. A lifting assembly is installed on the pressure guide arm. The tower leg components can be lifted by the lifting assembly to facilitate the assembly of the tower legs. The aforementioned lifting assembly includes a hook and a rope. The upper end of the rope is connected to the hook, and the lower end of the rope is connected to the tower leg assembly. By moving the straight boom, the tower leg assembly can be moved.

[0029] After the hoisting assembly is connected to the tower leg, the tower leg connected to the hoisting assembly can be moved by swinging and flipping the straight boom in the X direction. A power output component is hinged to the slide block. The output end of the power output component can be connected to the straight boom. When the two straight booms are connected by the traction seat 23 to form a lifting frame, the power output component is separated from the straight boom. However, when the two straight booms are connected by the pressure guide arm, the output end of the power output component can be connected to the straight boom. At this time, the operation of the power output component can make the straight boom rotate and swing, thereby driving the pressure guide arm to move. During this process, the tower leg components are moved. In this way, when assembling the tower legs, there is no need to use large hoisting equipment, which facilitates the assembly and construction of the tower legs.

When the two half arms 30 are not butted, the butt plate at the lower end of the half arm 30 can be butted with the extension plate 29 at the upper end of the bottom arm rod 27 through bolts, at this time, the bottom arm rod 27 and the upper arm rod 28 are locked by the half arm 30, so that they cannot be flipped relative to each other, thereby increasing the stability of the lifting frame.

[0031] The half arm 30 in the technical solution is provided with a plurality of groups of chuck assemblies, each of the chuck assemblies is provided with a recessed area, the chuck assembly is composed of two circular chucks 32, the area between the two circular chucks 32 is the recessed area, the diameter of the circular chuck 32 is greater than the diameter of the half arm 30, and when the pull rope on the traction system is located in the recessed area, the pull rope can be kept relatively stable through the setting of the chuck assembly.

[0032] Finally, the traction system in the technical solution further includes a pull line controller, the pull line controller is connected with the pull rope, the pull line controller is connected with the ground anchor through the pull rope, and when the pull line controller winds up the pull rope, the traction action is realized.
