Technical Field
[0001] This utility model belongs to the field of overhead line construction equipment, and specifically relates to a crossing frame used to assist in the construction of overhead lines. Background Technology
[0002] According to the regulations of the power grid company's on-site operation violation deduction management method (2024 edition), the prohibited category includes "failure to take safety measures such as erecting crossing frames, closing navigation, and closing roads when laying or removing power lines that cross various lines, railways, highways, rivers, etc." In order to prevent such violations, crossing frames must be erected when working under such conditions. The main function of the crossing frame is to support the power lines, maintain the stability of the lines when laying or removing power lines that cross various lines, railways, highways, rivers, etc., avoid interference and contact between the lines and obstacles, and ensure the safety of power transmission and construction operations.
[0003] Existing overhead crossings are mainly constructed from bamboo and wooden poles, and are typically assembled on-site according to the conditions of the construction site. Because their assembly and disassembly are very complex and time-consuming, they significantly impact construction efficiency. To improve efficiency, prefabricated overhead crossings exist; however, due to their size and weight, they usually require the use of large engineering machinery and have high requirements for the construction site. They are difficult to apply to small-scale overhead line construction operations in rural roads, fields, and mountainous areas. Therefore, a more flexible overhead crossing system is needed to improve construction efficiency. Utility Model Content
[0004] To overcome the shortcomings and problems of existing technologies and improve the erection efficiency and flexibility of crossing frames, this utility model provides a crossing frame for assisting the construction of overhead lines.
[0005] This utility model is achieved through the following technical solution:
[0006] A crossing frame for assisting overhead line construction includes support rods and support bases. Each support rod is composed of at least two connected components, and at least three support rods are provided. The bottom of the support base has a hinged portion, and one end of each support rod is hinged to the hinged portion. A crossbar is provided between each adjacent support rod, and both ends of the crossbar have fastening assemblies. The crossbar is fixedly connected to the support rod via the fastening assemblies. One end of each support rod has an anti-slip component, and a spacing adjustment rod is provided between the anti-slip component and the support rod. Both ends of the top of the support base have rotating shaft seats, and a line-carrying rod is connected between two rotating shaft seats. An insulating rod is provided on the top of each of the two rotating shaft seats. Both ends of the support base also have connecting portions, and the connecting portions have fixing holes for connecting windproof ropes.
[0007] The bottom circumference of the hinge part has several hinge slots, and the end of each support rod is connected to one hinge slot.
[0008] The fastening assembly includes a fastener base and a fastener. The fastener base is connected to the end of the crossbar, and the fastener is connected to the fastener base. Both the fastener base and the fastener base are arc-shaped structures. When the fastener base and the fastener base are fastened together, a buckle is formed between them.
[0009] One end of the fastener and one end of the fastener base are hinged together. The other end of the fastener and the other end of the fastener base are both provided with locking parts. Both locking parts are provided with through slots. The fastening assembly also includes a locking bolt, which passes through the two through slots and is connected to a locking nut.
[0010] One end of the locking bolt is provided with an anti-rotation part, which is in concave-convex fit with one of the locking parts.
[0011] The anti-slip component is located at the end of the spacing adjustment rod, which is threadedly connected to the support rod. The spacing between the anti-slip component and the support rod can be adjusted by rotating the spacing adjustment rod.
[0012] The anti-slip component has a cap-like structure, and anti-slip teeth are provided around the bottom perimeter of the anti-slip component.
[0013] The connecting part is a horizontally arranged plate, and the fixing holes are provided in a plurality of them, which are evenly spaced around the end of the support base and correspond to the two sides and the end of the support base respectively.
[0014] The insulating rod can be installed at an angle or vertically.
[0015] Both the rotating shaft seat and the insulating rod are made of insulating material.
[0016] The beneficial effects of this utility model are as follows:
[0017] The main components of this invention, such as the support rods, crossbars, and support bases, are all designed to be detachable. Disassembling these components during transportation effectively saves space. During assembly, simply assembling the support rods, support bases, and crossbars and connecting them allows the scaffolding to function normally. The assembly process is simple and quick, effectively improving construction efficiency. The crossbars secure the support rods together, enhancing the stability of the scaffolding. The crossbars are connected to the support rods via fastening components, allowing for quick connection and disconnection.
[0018] The spacing adjustment rod of this utility model is provided with an anti-slip component at its end. The anti-slip component can prevent the support rod from sliding during erection, thereby improving the stability of the crossing frame. At the same time, the spacing adjustment rod can control the anti-slip component to move closer to or further away from the end of the support rod, thereby adjusting the height of the anti-slip component and enabling the crossing frame to effectively maintain a horizontal state when facing uneven ground.

Detailed Implementation
[0028] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] like Figure 1 , 2As shown in Figure 3, a crossing frame for assisting in the construction of overhead lines includes a support rod 100 and a support base 200. The support rod 100 supports the support base 200, which in turn supports the overhead line. Both ends of the top of the support base 200 are provided with pivot seats 201, and a line-bearing pole 220 is connected between the two pivot seats 201. The line-bearing pole 220 is the main component supporting the overhead line and is in direct contact with it. When the overhead line needs to be pulled, the line-bearing pole 220 can rotate to prevent wear on the surface of the overhead line. The top of each of the two pivot seats 201 is provided with an insulating rod 202. The insulating rod 202 is inclined to effectively prevent the overhead line from slipping off the line-bearing pole 220 and to prevent the line from contacting the support base 200. In this embodiment, the support rod 100 and support base 200 need to have a certain rigidity, so they are preferably made of metal. Since metal is conductive, the pivot seat 201 and insulating rod 202 in this embodiment are both made of insulating material, which can prevent the circuit from conducting current to the support rod 100 and support base 200, and ensure the personal safety of the operator.
[0030] like Figure 1 , 2 As shown in Figure 3, the support rod 100 is composed of three connected components. The adjacent ends of each adjacent component are connected by a sleeve and fixed with bolts, which facilitates assembly and disassembly. There are three support rods 100. The bottom of the support base 200 is provided with a hinge part 210. The bottom circumference of the hinge part 210 has three hinge slots 211. One end of each support rod 100 is connected to the hinge slot 211. The support rod 100 and the hinge part 210 are connected to form a stable tripod structure, thereby achieving stable support for the support base 200 and effectively crossing obstacles. In practical applications, the erection angle of the support rod 100 can be adjusted according to the requirements of the construction site. The hinge slot 211 and the support rod 100 can be connected by a rotating shaft or ordinary bolts. By passing the rotating shaft or bolts through the two side walls of the hinge slot 211 and the support rod 100, the support rod 100 can be connected to the hinge slot 211. This connection structure is simple and quick to assemble and disassemble, which is convenient for the disassembly, assembly and transportation of the gantry frame.
[0031] like Figure 3 , 4As shown, the support base 200 is further provided with connecting portions 230 at both ends. Each connecting portion 230 has fixing holes 231 for connecting windproof ropes. The connecting portion 230 is a horizontally arranged plate. Several fixing holes 231 are evenly spaced around the ends of the support base 200, corresponding to the sides and ends of the support base 200. In practical applications, the buckles on the windproof ropes can be connected to the fixing holes 231 to improve the stability of the crossing frame. Multiple fixing holes 231 ensure that the windproof ropes can be connected to the support base 200 in the appropriate direction.
[0032] like Figure 5 As shown, one end of the support rod 100 is provided with an anti-slip element 111, and a spacing adjustment rod 110 is provided between the anti-slip element 111 and the support rod 100. The anti-slip element 111 has a cap-like structure, and anti-slip teeth 112 are provided around the bottom periphery of the anti-slip element 111 to prevent the support rod 100 from sliding. The anti-slip element 111 is located at the end of the spacing adjustment rod 110, which is threadedly connected to the support rod 100. By rotating the spacing adjustment rod 110, the spacing between the anti-slip element 111 and the support rod 100 can be adjusted. When facing uneven ground, the height of each anti-slip element 111 can be quickly adjusted by the spacing adjustment rod 110 to ensure that the support base 200 can remain horizontal, thereby improving the stability and adjustment flexibility of the scaffold support.
[0033] like Figure 6 , 7 As shown in Figure 8, a crossbar 120 is provided between each adjacent support rod 100. The crossbar 120 is used to support and fix the support rod 100 to prevent it from loosening after it is erected. Each end of the crossbar 120 is provided with a fastening assembly 130, and the crossbar 120 is fixedly connected to the support rod 100 through the fastening assembly 130. The fastening assembly 130 includes a fastener 131 and a fastener 132. The fastener 131 is hinged to the end of the crossbar 120, and the fastener 132 is connected to the fastener 131. Both the fastener 131 and the fastener 132 are arc-shaped structures. When the fastener 131 and the fastener 132 are fastened, a buckle is formed between them, which can be used to tighten the support rod 100. One end of the fastener 132 is hinged to one end of the buckle seat 131. The other end of the fastener 132 and the other end of the buckle seat 131 are both provided with locking parts 133. Both locking parts 133 are provided with through slots 134. The fastening assembly 130 also includes a locking bolt 135, which passes through the two through slots 134 and is connected to a locking nut 136.
[0034] When disassembling the crossbar 120, simply remove the locking bolt 135 and then open the fastener 132. When installing the crossbar 120, fasten the fastener seat 131 and the fastener 132 onto the support rod 100, and then use the locking bolt 135 to fix the fastener 132 and the fastener seat 131. The disassembly and assembly process is simple and efficient. One end of the locking bolt 135 is provided with an anti-rotation part 137, which engages with a locking part 133. The anti-rotation part 137 can prevent the locking bolt 135 from rotating, so that the locking nut 136 can be tightened quickly without the need for manual tightening of the locking nut 136 while simultaneously fixing the locking bolt 135. It also prevents the locking bolt 135 from coming out of the through groove 134 after tightening.
[0035] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
