[0027] Embodiment: Refer to Figures 1 to 4, the present invention provides a construction device for erecting cables, which includes a vertically arranged vertical rod assembly, a horizontally arranged cross rod assembly, and a pulling rope 1 for pulling the vertical rod assembly and / or the cross rod assembly. The bottom end of the vertical rod assembly is connected to the ground surface, and the cross rod assembly is connected to the upper end of the vertical rod assembly. The vertical rod assembly is composed of several vertical pipe segments 2 connected in sequence. Adjacent vertical pipe segments 2 are connected by a first connecting seat 3. Among them, a first connecting seat 3 located in the middle of the vertical rod assembly is provided with a flange ring 4. The flange ring 4 is detachably sleeved on the outer wall of the first connecting seat 3. The outer wall of the first connecting seat 3 is provided with a flange 5 for restricting the movement of the flange ring 4. The flange ring 4 is provided with a first pulling hole 6 along the circumference. One end of the pulling rope 1 is connected to the first pulling hole 6, and the other end of the pulling rope 1 is fixedly connected to the ground surface. By using the vertical rod assembly, the cross rod assembly and the pulling rope 1, a crossing frame can be built. The disassembly and assembly process is convenient and fast. Through on-site operation statistics, the assembly time is about ten minutes, and the disassembly time is about five minutes, which greatly improves the construction efficiency. At the same time, it can be reused, significantly reducing the cost. The vertical rod assembly is composed of several vertical pipe segments 2 connected in sequence. After being disassembled as a whole, it can be put into a bag, which is convenient to carry and can be applied to various site conditions.

[0028] Specifically, through holes 7 penetrating both sides of the first connecting seat 3 are formed at both ends of the first connecting seat 3. The end of the vertical pipe section 2 is provided with a second through hole penetrating both sides of the vertical pipe section 2 and corresponding to the first through hole 7. A fastening bolt (not shown in the figure) is arranged through the first through hole 7 and the second through hole. The first connecting seat 3 is used to connect two adjacent vertical pipe sections 2, and the fastening bolt is used for locking and fixing, so the assembly is convenient and fast. The cross-bar assembly includes a transverse pipe section 8 located in the middle position and extension pipe sections 9 extending outward from both ends of the transverse pipe section 8. The transverse pipe section 8 is connected to the uppermost vertical pipe section 2 through a tee connector 10. The transverse pipe section 8 penetrates through two ports of the tee connector 10 and is centered. Centering the transverse pipe section 8 can ensure its strength and make it more stable when bearing the acting force of the cable. Then, the extension pipe sections 9 are arranged as needed, and the structure is scientific and reasonable. The extension pipe section 9 is connected to the transverse pipe section 8 through a second connecting seat. A second pulling hole for connecting the pulling rope 1 is arranged on the outer wall of the second connecting seat. In this embodiment, the second connecting seat has the same specification as the first connecting seat 3, and a flange ring 4 is also sleeved on its outer wall. The flange ring 4 has the same second pulling hole as the first pulling hole 6. A limiting rod 11 extends upward on the outer side of the extension pipe section 9. A limiting hole adapted to the limiting rod 11 is arranged on the outer wall of the end of the extension pipe section 9. One end of the limiting rod 11 is inserted into the limiting hole. The limiting rod 11 has a limiting effect on the cable placed on the cross-bar assembly. The bottom end of the vertical rod assembly is fixedly connected to the ground surface through a fixing seat. The fixing seat includes a fixing plate 12 and a connecting plate 13. The fixing plate 12 is hinged to the connecting plate 13. The fixing plate 12 is fixedly connected to the ground surface. A fixing groove 14 adapted to the end of the vertical pipe section 2 is arranged on the end face of the connecting plate 13. The transverse pipe section 8 and the vertical pipe section 2 are made of the same specification of pipe material, and the cross section of the pipe material is in the shape of a Reuleaux triangle, so that the structure has better strength. Four fixing points 15 for fixing the pulling rope 1 are arranged on the ground surface. The four fixing points 15 are symmetrically distributed with the connection point of the end of the vertical rod assembly on the ground surface as the center, and the four fixing points 15 are symmetrically distributed with the cross-bar assembly as the axis of symmetry. The pulling rope 1 for pulling the cross-bar assembly and the vertical rod assembly shares the four fixing points 15, which can not only ensure the balanced force of the spanning frame, but also reduce the construction time consumed by setting too many fixing points 15, and further improve the construction efficiency.

[0029] Disassembly and assembly process of the embodiment of the present invention:

[0030] During assembly, first determine the center point, install and fix the fixing plate 12 of the fixing base at the center point. Use the first connecting seat 3 to sequentially connect several transverse pipe sections 8 into a vertical rod assembly, and assemble one end of the vertical rod assembly into the fixing groove 14 of the connecting plate 13. Sleeve a flange ring 4 on the first connecting seat 3 in the middle of the vertical rod assembly, and the end of the first connecting seat 3 with a flange 5 faces the side of the fixing base. That is, when the vertical rod assembly is erected, the flange 5 is located on the lower side, which can prevent the flange ring 4 from falling off downward. At the same time, the detachable sleeve connection is adopted, and the flange ring 4 can be configured on the first connecting seat 3 where the pulling rope 1 needs to be connected, saving material costs. Then, connect the transverse pipe section 8 on the side of the vertical rod assembly away from the fixing base through a tee connector 10. Then, connect the extension pipe section 9 at both ends of the transverse pipe section 8 by using the second connecting seat, and install a limiting hole at the end of the extension pipe section 9 away from the second connecting seat. Then, connect four pulling ropes 1 to the first connecting seat 3, and connect two pulling ropes 1 to each second connecting seat. Then, take the intersection of the fixing plate 12 and the connecting plate 13 as the rotation axis to erect the vertical rod assembly from the ground. At the same time, set four fixing points 15 around the center point, and fix the other ends of the pulling ropes 1 to the four fixing points 15 respectively, so that the spanning frame is stressed evenly in four directions and the structure is more stable.

[0031] Conversely, the spanning frame can be disassembled and put into a bag for easy carrying.

[0032] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
