[0003] To prevent the conductor from breaking, sagging, and contacting the energized line, and to ensure public safety, before the construction operation of crossing highways and railways, it is necessary to first erect a safety net, that is, "net covering". During the construction process, it is necessary to first install crossing frames in pairs on both sides of the railway. A tower head structure is provided at the top of the crossing frames. A set of cable ropes is fixedly connected between the tower heads at the corresponding positions of the two groups.

Specific implementation manner

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 , in the embodiment of the present invention, a net enclosing tower head structure includes a tower head beam frame 101. A top frame 104 is fixedly connected to the center of the top of the tower head beam frame 101. Both ends of the top frame 104 are rotatably connected to horn-shaped rods 103. Both bottoms of the two horn-shaped rods 103 are rotatably connected to vertical supports 102. The bottoms of the vertical supports 102 are rotatably connected to the tower head beam frame 101. Rollers 109 are rotatably installed on the top of the top frame 104 and the tops of the two horn-shaped rods 103; inclined supports 108 are fixedly connected to both sides of the top of the tower head beam frame 101; the above is the basic structure of the tower head structure. Through the setting of the horn-shaped rods 103 and the rollers 109 on the top frame 104, when the conductor sags and slips, the conductor is received, and the inclined horn-shaped rods 103 are used to guide it, so that the sagging conductor is concentrated towards the middle of the tower head, avoiding the scattered falling of the conductor;

[0037] To achieve the integrated installation of the net enclosing, a supporting component 2 is fixedly installed on one side of the tower head beam frame 101, that is, the supporting component 2 is used to temporarily load the net enclosing. During the assembly and lifting of the tower head and the main body of the spanning frame, the net enclosing is lifted and positioned integrally, so that there is no need to manually lift and position the net enclosing additionally.

[0038] Please refer to Figure 2, the supporting component 2 includes two fixed sleeve rods 202. The inner walls of the two fixed sleeve rods 202 are both slidably connected with movable rods 203. The bottoms of the two fixed sleeve rods 202 and the two movable sleeve rods are both fixedly connected with hanging rings 204. One ends of the two movable rods 203 are commonly connected with a traction frame 201. Both ends on one side of the traction frame 201 are fixedly connected with hanging parts for hanging with the netting cable 106. During the installation of the netting, its two ends are respectively fixed to the hanging rings 204 on the fixed sleeve rods 202 and the movable sleeve rods. The end of the netting fixed to the hanging ring 204 of the fixed sleeve rod 202 is called the fixed end, and the end fixed to the hanging ring 204 of the fixed sleeve rod 202 is called the movable end. When unfolding the netting, it is hung with the netting cable 106 through the hanging part. By the sliding of the traction frame 201 along the movement of the netting cable 106 to drive the movement of the movable rod 203, and then pulling the netting to move to achieve unfolding.

[0039] To facilitate the pulling and moving of the traction frame 201, a traction rod 208 is fixedly connected to the middle of one side of the traction frame 201. By the way of setting the traction rod 208 in the middle of the traction frame 201 for traction, it can ensure the relative consistency of the moving distances at both ends during the moving process, and effectively avoid the problem of increased movement resistance caused by the inclination of the traction frame 201.

[0040] The hanging part includes a connecting base frame 205. One end of the base frame 205 is fixedly installed with a turning motor 206. The output end of the turning motor 206 is fixedly connected with a hanging frame 2071. Please refer to Figure 3 , two hanging buckles 2074 are slidably connected to the top of the hanging frame 2071; by driving the hanging frame 2071 to lift and lower through the turning motor 206, it makes a downward avoidance during the installation process of the netting cable 106, and lifts when installing the netting, so that the hanging buckles 2074 are butted with the netting cable 106.

[0041] In this application, the hanging buckles 2074 are set as semi-circular, and the two hanging buckles 2074 are mutually close to enclose a hanging ring. The hanging part is connected with the netting cable 106 through the sliding connection of the hanging ring with the netting cable 106;

[0042] Both bottoms of the two hanging buckles 2074 are fixedly connected with pushing plates 2072. Tooth grooves are opened at the bottoms of the two pushing plates 2072. Below the two pushing plates 2072, driving motors are arranged. The output ends of the two driving motors are both fixedly connected with driving gears 2073. The two driving gears 2073 are respectively meshed with the two tooth grooves. By driving the driving gears 2073 to rotate through the driving motors, and then driving the pushing plates 2072 to shift, the displacement control of the two hanging buckles 2074 is realized.

[0043] To reduce the resistance of the hanging part during the displacement movement, a driving guide wheel 2075 is rotatably installed on the inner wall of the hanging buckle 2074.

[0044] Please refer to Figure 2 , for the installation of the netting cable 106, placing grooves are provided on both sides of the top of the traction frame 201. The end plates 105 are snap-fitted in the placing grooves. One side of the end plate 105 is fixedly connected to the netting cable 106. By setting the snap connection of the placing frame and the end plate 105, when the tower head structure is installed, the installation of the netting cable 106 can be completed synchronously, thereby improving the installation efficiency.

[0045] Please refer to Figure 4 , a guiding ring 107 is fixedly connected to the side of the tower head beam frame 101 away from the traction frame 201. During the installation of the netting cable 106, the guiding ring 107 is used to limit it, preventing the cable from being displaced excessively due to traction and shaking and disengaging from the supporting roller 3013.

[0046] Please refer to Figure 4 and Figure 5 , installation components 3 for installing the netting cable 106 are provided at both ends of the tower head beam frame 101. The installation component 3 includes an installation groove, and a supporting member or a limiting member is provided in the installation groove. During the construction process, two spanning frames on both sides of the railway 110 form a group. In one of the spanning frames, the installation groove thereon is used to install the supporting member, and in the other spanning frame, the installation groove thereon is used to install the limiting member. A corresponding supporting member and a limiting member form a group for realizing the limiting and fixing of a netting cable 106. For the installed state of a group, please refer to Figure 7 , for the specific states after multiple groups are installed, refer to Figure 8 , Figure 8 , in

[0047] Please refer to Figure 4 , the supporting member includes a supporting table 3012, a supporting roller 3013 is rotatably installed on the top of the supporting table 3012, and a supporting groove is provided in the middle of the supporting roller 3013; the limiting member includes a limiting table 3022, and a clamping groove is provided in the middle of the limiting table 3022. Both the supporting table 3012 and the limiting table 3022 can rotate on the inner wall of the installation groove, so that when there is a certain degree of horizontal misalignment between two tower head structures, through the rotation of the supporting table 3012 and the limiting table 3022, the netting cable 106 can complete the connection between the two tower heads in an inclined state.

[0048] Please refer to Figure 5 and Figure 6, to detect the tension of the network - closing cable 106, a detecting member is fixedly installed on the inner wall of the clamping groove.

Fix one end of the network - closing cable 106 to the guiding ring 107. Then, pass the end with the end plate up from below the guiding ring 107 and bypass the supporting groove on the supporting roller 3013, and then clamp the end head plate 105 of the end into the placing groove. Then, use an external hoisting and installation device to integrally install the tower head on the top of the spanning frame. Compared with the existing scheme of manually climbing the tower head to sequentially install the network - closing cable 106 and the network - closing after the overall installation of the tower head, the scheme of the present application can effectively save working hours and improve construction safety;

[0052] Then, install the network - closing cable 106. Remove the end head plate 105 manually or by a construction device and pull the network - closing cable 106 to move, and install the end head plate 105 into the limiting member on the ending frame to complete the installation of one cable;

[0053] Then, the flipping motor 206 starts to work, driving the hanging frame 2071 to flip and lift, so that the two hanging buckles 2074 are located on both sides of the netting cable 106. Then, the two driving motors start, driving the driving gears 2073 to rotate, and further driving the two pushing plates 2072 to move closer to each other, driving the two hanging hooks to approach and enclose the cable, realizing the connection between the hanging member and the netting cable 106. Then, the traction frame 201 is pulled by manual or construction equipment to move, and further drives the movable rod 203 and the hanging ring 204 thereon to move, pulling the netting to unfold; when the traction frame 201 drives the netting to move to one end close to the end frame, the traction frame 201 is fixed by a binding rope to complete the installation of the netting.
