[0011] Advantages of the present invention compared with the prior art:

[0012] The double rocker arm and double flat arm universal gin pole of the present invention provides users with an additional option during construction. The double rocker arm and double flat arm gin poles each have their own advantages and disadvantages; users can freely choose according to the needs of the tower type of the erected iron tower and the construction terrain during the repair construction of power transmission and transformation, and realize the multi-purpose use of a set of gin poles. It can be used as a rocker arm gin pole and also as a flat arm gin pole, which provides a more convenient choice for construction units, reduces user costs, and improves construction efficiency.

[0013] The double rocker arm gin pole assembled by the present invention has a light and compact single-piece structure after being disassembled, which is convenient for single-piece handling. After assembly, it has a large bearing capacity and is suitable for places with unfavorable traffic in mountainous areas. The positioning and adjustment of the tower materials lifted by the rocker arm gin pole are realized through the undulation of the double rocker arms. Lifting the gin pole once can reach a tower building height of 15 meters to 30 meters.

[0014] Since the boom of the double horizontal boom gin pole of the present invention extends at least 21 meters and there are many gin pole segments, it is inconvenient to carry, so it is suitable for places where transportation can reach. The positioning (alignment) of the tower materials lifted by the horizontal boom gin pole is achieved through the movement of the trolley on the horizontal boom. When the gin pole is lifted once, the height of the assembled iron tower can be 15 meters to 20 meters.

[0015] The lifting weight of the double horizontal boom gin pole of the present invention decreases as the boom length increases. The lifting speed of the double horizontal boom gin pole and the translation speed of the trolley are both higher than those of the double swing arm gin pole. By selecting different gin poles, different construction requirements can be met respectively, improving the construction efficiency.

[0016] In the present invention, the pin assembly method is adopted between individual parts instead of the flange assembly method, which is beneficial to improving the construction speed. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0029] The following combines the attached Figure 1-11 Describe the specific embodiments of the present invention.

[0030] (As Figure 1 , Figure 2 shown) The rocker arm and flat arm universal gin pole has a universal main standard section 1, slewing bearing hinge support 2, boom 3 with equilateral triangle cross-section and square box 4.

[0031] (Combined with Figure 10 ) In the above embodiment, further: the main standard section 1 is a square frame structure, one end of the main standard section 1 has a vertically arranged double fork joint 101 and the other end has a vertically arranged single fork joint 102; when adjacent main standard sections 1 are butted, the double fork joint 101 and single fork joint 102 of adjacent main standard sections 1 are vertically inserted and matched and fastened together with a horizontal pin 103. The double fork joint 101 or single fork joint 102 at the upper or lower end of each main standard section 1 is arranged in one direction for quick insertion and assembly. Using the method of fastening together with a horizontal pin 103 to replace the original flange erection method can reduce the number of components, reduce the number of operations and improve the erection efficiency.

[0032] (Combined with Figure 9In the above embodiments, further: The top end of the slewing bearing articulated support 2 has a slewing articulated connection box body 202; A slewing articulated seat body 201 is provided outside the slewing articulated connection box body 202, and the slewing articulated seat body 201 is integrally and removably connected to the vertical outer side wall of the slewing articulated connection box body 202 in a fastening manner; The slewing articulated seat body 201 and the slewing articulated connection box body 202 are designed as a detachable structure to facilitate miniaturization and lightweight of the single-piece weight for turnover and transportation in mountainous areas. Among them, the slewing articulated seat body 201 is specifically used for articulating the rocker arm variable section 5 (in combination with Figure 1 , Figure 3 , Figure 5 ) for use when assembling the rocker arm gin pole.

[0033] (As shown in Figure 5 , Figure 6 ) In the above embodiments, further: The square box 4 is a regular square frame structure; As described later, the square box 4 is fixedly installed at the top end of the slewing bearing articulated support 2. The top end of the square box 4 can be used for assembling the flat arm mast cone section 12 and can also be used for assembling the rocker arm mast transition section 7. When the top end of the square box 4 assembles the flat arm mast cone section 12, it is used to form the mast of the flat arm gin pole; When the top end of the square box assembles the rocker arm mast transition section 7, it is used to form the mast of the rocker arm gin pole. Among them, the square box 4 is characterized in that: Isosceles triangle connecting ear plates 402 are respectively provided at the top corners of the square box 4 (in combination with Figure 11 of the enlarged detailed structure schematic diagram), and the top corners of the isosceles triangle connecting ear plates 402 are welded and fixedly connected to the four corners of the square box 4 as a whole; Ear plate connection holes 4021 are respectively made at the two base angles of the isosceles base of the isosceles triangle connecting ear plates 402. It should be noted that: The eight ear plate connection holes 4021 provided at the top corners of the square box 4 respectively form upper ear plate connection holes, lower ear plate connection holes, and side ear plate connection holes. Among them, the upper ear plate connection holes are used to fixedly connect and assemble the bottom end of the flat arm mast cone section 12 or the rocker arm mast transition section 7 using a pin; The lower ear plate connection holes are used to fixedly connect and assemble the top end of the slewing bearing articulated support 2 using a pin; The side ear plate connection holes are used to fixedly connect and assemble the double flat arms using a pin (as shown in Figure 6 ). Similarly, the connection and assembly between all components are assembled by pin connection. Compared with flange plates, the assembly with fasteners has the advantages of being more convenient and faster.

[0034] On this basis: (As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 ) The top end of the main standard section 1 is fixedly connected to the bottom end of the slewing bearing articulated support 2; The top end of the slewing bearing articulated support 2 is fixedly connected to the bottom end of the square box 4 (in combination with Figure 11). The main standard section 1 can be vertically assembled by multiple sections, and the number of assembled sections can be increased or decreased according to the required height. The slewing bearing articulated support 2 is used to realize the rotation and slewing functions of the double swing arms or double horizontal arms.

[0035] When it is necessary to form a double swing arm gin pole: (as Figure 5 shown) When the slewing bearing articulated support 2 is articulated with the inner end of the swing arm variable section 5 through the slewing articulated seat body 201, the outer end of the swing arm variable section 5 is fixedly connected to the inner end of the boom 3 arranged in an inverted triangle, the outermost ends of multiple sections of the boom 3 are fixedly connected to the swing arm lifting head 6, the top of the square box 4 is fixedly connected to the swing arm mast transition section 7, and the top of the swing arm mast transition section 7 is fixedly connected to the swing arm mast cone section 8 (in combination with Figure 3 , Figure 1 ), the main standard section 1, the slewing bearing articulated support 2, the boom 3 arranged in an inverted triangle, the square box 4, the swing arm variable section 5, the swing arm lifting head 6, the swing arm mast transition section 7, and the swing arm cone mast 8 form a swing arm gin pole. Among them, one end of the swing arm lifting head 6 is pin-connected and fixedly connected to the regular triangular cross-section at the outer end of the boom 3 arranged in an inverted triangle as a whole; the structure and function of the other end of the swing arm lifting head 6 are the same as those of the existing swing arm lifting head 6. The swing arm mast transition section 7 is used to increase the mast height of the swing arm so as to adjust the swing arm pitching angle.

[0036] It should be noted that the connection method between multiple sections of the boom 3 is the same as the assembly method of the multiple sections of the main standard section 1 described above, and will not be elaborated here. The effect is that it is more convenient and faster than the flange combination method.

[0037] When it is necessary to form a double horizontal arm gin pole: (as Figure 6 shown) When the square box 4 is fixedly connected to the inner end of the horizontal arm variable section 9, the outer end of the horizontal arm variable section 9 is fixedly connected to the inner end of the boom 3 arranged in a regular triangle, the outer ends of multiple sections of the boom 3 are fixedly connected to the horizontal arm end 10 (in combination with Figure 4 , Figure 2 ), the bottom end of the boom 3 arranged in a regular triangle is installed with a mobile trolley 11 by rolling friction support, and the installation method of the mobile trolley 11 on the horizontal arm is the same as the existing structure. When the top of the square box 4 is fixedly connected to the horizontal arm mast cone section 12, the main standard section 1, the slewing bearing articulated support 2, the boom 3 arranged in an inverted triangle, the square box 4, the horizontal arm variable section 9, the horizontal arm end 10, the mobile trolley 11, and the horizontal arm mast cone section 12 form a horizontal arm gin pole. Similarly, one end of the horizontal arm end 10 is pin-connected and fixedly connected to the regular triangular cross-section at the outer end of the boom 3 arranged in a regular triangle as a whole; the function of the other end of the horizontal arm end 10 is the same as the functional structure of the existing horizontal arm end 10.

[0038] In the above embodiments, further: (as Figure 6As shown in the figure, the boom 3 is made of square pipes welded together to form an equilateral triangle frame structure. In the middle of the square pipe in the length direction at the triangular vertex of the boom 3 used as an equilateral triangle, there is a guy wire joint 301; the guy wire joint 301 is connected to the top end of the flat arm mast cone section 12 through a guy wire 302 to form a flat arm gin pole.

[0039] In the above embodiment, further: (as Figure 5 shown in the figure) One end of the rocker change section 5 is provided with a hinge ear plate 501, and the other end of the rocker change section 5 is a frame Ⅰ 502 with an equilateral triangle cross-section; the hinge ear plate 501 is hinged to the rotary hinge seat body 201 of the rotary support hinge support 2; the frame Ⅰ 502 with an equilateral triangle cross-section is fixedly connected to the inverted equilateral triangle cross-section of the boom 3 by pin connection. That is, the rocker change section 5 realizes the transitional connection between the rotary support hinge support 2 and the inverted boom 3.

[0040] In the above embodiment, further: (as Figure 6 shown in the figure) One end of the flat arm change section 9 is provided with a frame Ⅰ 901 with a square cross-section, and the other end of the flat arm change section 9 is provided with a frame Ⅱ 902 with an equilateral triangle cross-section; the frame Ⅰ 901 with a square cross-section is fixedly connected to the frame Ⅱ 401 with a square cross-section of the square box 4; the frame Ⅱ 902 with an equilateral triangle cross-section is fixedly connected to the equilateral triangle cross-section of the boom 3 arranged forward. That is, the flat arm change section 9 realizes the transitional connection between the square box 4 and the boom 3 arranged forward.

[0041] The working principle of the present invention is as follows: In actual use: Since the square box 4 is a box frame structure with dimensions of 770×770×770 mm. The boom 3 is an equilateral triangle frame structure with a length of 4 meters and a side length of 700 mm. Therefore, the assembled double-rocker gin pole has a height of 16.5 meters. Connect the 16-meter-long double rocker to the side of the rotary support hinge support 2 by hinge, and this gin pole forms a double-rocker gin pole. When the boom 3 forms a 21-meter flat arm, the flat arm is fixedly connected to the 770×770×770 mm square box 4, and this gin pole becomes a 21-meter-arm ground double-flat-arm gin pole. This gin pole is suitable for users to choose different gin poles according to different terrains and the tower shapes of the assembled iron towers, which is convenient for construction and allows for flexible and free combination and selection.

[0042] It can be found through the above description that: The double-rocker and double-flat-arm universal gin pole of the present invention provides users with one more choice in construction. The double-rocker and double-flat-arm gin poles have their own advantages and disadvantages; users can freely choose according to the needs of the tower shape of the assembled iron tower and the construction terrain in the transmission and substation repair construction, so as to realize the multi-purpose use of a set of gin poles. It can be used as a rocker gin pole and also as a flat-arm gin pole, which provides a more convenient choice for construction units, reduces user costs, and improves construction efficiency.

[0043] The single-piece structure of the double swing arm gin pole assembled by the present invention is light and handy after disassembly, facilitating single-piece handling. After assembly, it has a large bearing capacity and is suitable for places with unfavorable transportation in mountainous areas. The positioning and adjustment of the tower materials lifted by the swing arm gin pole are achieved through the undulation of the double swing arms. Lifting the gin pole once can achieve a tower erection height of 15 to 30 meters.

[0044] One side of the double horizontal arm gin pole of the present invention can be assembled by five large arms 3 each 3 meters long. Since the large arm extends at least 21 meters and there are many gin pole segments, handling is relatively inconvenient, so it is suitable for places where transportation can reach. The positioning (adjustment) of the tower materials lifted by the horizontal arm gin pole is achieved through the movement of the moving trolley 11 on the horizontal arm. Lifting the gin pole once can achieve a tower erection height of 15 to 20 meters.

[0045] The lifting weight of the double horizontal arm gin pole of the present invention decreases as the length of the large arm increases; the lifting speed of the double horizontal arm gin pole and the translation speed of the moving trolley 11 are both higher than those of the double swing arm gin pole. Selecting different gin poles can meet different construction requirements respectively and improve construction efficiency.

[0046] Between the single pieces of the present invention, the pin assembly method is used instead of the flange assembly method, which is beneficial to improving the construction speed.

[0047] In summary, a swing arm and horizontal arm universal gin pole provided by the present invention uses a universal main standard section 1, a slewing bearing hinge support 2, an equilateral triangle large arm 3, and a square box 4. One set of gin poles can be used in multiple ways. When the large arm 3 is installed and used in an inverted triangle manner, connecting the swing arm variable section 5, the swing arm lifting head 6, the swing arm mast transition section 7, and the swing arm cone mast 8 forms a swing arm gin pole; when the large arm 3 is installed and used in an equilateral triangle manner, connecting the horizontal arm variable section 9, the horizontal arm end 10, the moving trolley 11, and the horizontal arm mast cone section 12 can form a horizontal arm gin pole. It can be used as both a swing arm gin pole and a horizontal arm gin pole, providing a more convenient choice for construction units, reducing the cost of users, and improving construction efficiency.
