DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-5 , the utility model provides an embodiment: a safe sliding contact line movable sliding contact clamp, including crossbeam 1 and the U-shaped sheet metal frame 2 of welding installation on the both sides of crossbeam 1 bottom end, the both sides of the top of crossbeam 1 are all fixed with U-shaped frame 3, and the opposite side outer wall on two U-shaped frames 3 is installed with elastic support structure, and the end away from U-shaped frame 3 of elastic support structure is installed with guide plate 6, and the double-layer multi-position sliding wire clamp 5 that is extended upwards and is supported by multiple cables is installed between two guide plates 6, and the inside of U-shaped frame 3 is installed with hydraulic damper 4, and the piston rod top of hydraulic damper 4 is connected with the other end of elastic support structure;

[0020] When the plurality of cables are forced to shift the double-layer multi-position sliding wire clamp 5 to the hydraulic damper 4 in one direction, the hydraulic damper 4 can exert effective damping effect on the cables and the double-layer multi-position sliding wire clamp 5, so as to ensure that the hydraulic damper 4 can timely absorb the impact force when the wind changes, and avoid the cables from swinging violently. In this process, the other hydraulic damper 4 not subjected to force processes the stretching state, so as to pull back the double-layer multi-position sliding wire clamp 5 in the shifting process. At this time, the two hydraulic dampers 4 jointly act;

[0021] The cross beam 1 and the U-shaped metal frame 2 are made of stainless steel components. The U-shaped metal frame 2 is provided with a plurality of through holes on the outer walls and the bottom end.

[0022] The cross beam 1 is fixed on the horizontal support of the electric pole through the U-shaped metal frame 2 and the through holes on the bottom surface and the outer wall surface of the U-shaped metal frame 2, so as to ensure that the sliding wire clamp is stably installed.

[0023] The elastic support structure includes a baffle 401 integrally formed at one end inside the hydraulic damper 4, guide rods 601 slidingly installed on both sides inside the baffle 401, and a helical spring 602 wound on the outer circumferential surface of the guide rod 601. One end of the guide rod 601 is fixedly connected with one side of the guide plate 6. When the double-layer multi-position sliding wire clamp 5 slides along the extension direction of the cross beam 1, the double-layer multi-position sliding wire clamp 5 drives the guide plate 6 to slide towards the baffle 401. At this time, the guide rod 601 and the baffle 401 relatively slide, and the helical spring 602 is compressed. The helical spring 602 cooperates with the hydraulic damper 4 to slow down the movement amplitude of the cables and the double-layer multi-position sliding wire clamp 5.

[0024] The double-layer multi-position sliding wire clamp 5 includes a vertical plate 501 fixed between the two guide plates 6, a plurality of wing plates 503 installed from top to bottom on the outer walls of the two sides of the vertical plate 501, and a half-open type clamp 504 integrally formed at one end of the wing plate 503 away from the vertical plate 501. The top end of the wing plate 503 on one side of the half-open type clamp 504 is integrally formed with a clamp two 505. One end of the half-open type clamp 504 and the clamp two 505 is bolted with the top end of the wing plate 503. The bottom end of the vertical plate 501 is integrally formed with a connecting leg 502 for bolting with the guide plate 6.

[0025] When the cables are installed into the double-layer multi-position sliding wire clamp 5, the staff pulls the half-open type clamp 504 and the clamp two 505 outward, so that a large enough opening appears between the half-open type clamp 504, the clamp two 505 and the wing plate 503 for embedding the cables. Then, the half-open type clamp 504 and the clamp two 505 are bolted to make the cables stably placed in the half-open type clamp 504 and the clamp two 505. This structure can support the cables in multiple layers respectively, and improve the cable capacity of the sliding wire clamp.

[0026] The top wall of the hoop two 505 is integrally formed with a herringbone spacer 506, and the herringbone spacer 506 is located in the hoop two 505, so that three chambers are formed in the hoop two 505, and then three cables are accommodated.

[0027] In use, the staff first ensures that all accessories and materials are complete, that the double-layer multi-position sliding wire clamp 5, the cross beam 1, the U-shaped sheet metal frame 2, the hydraulic damper 4, the elastic support structure and other components are not damaged, and that the stability of the electric pole and the horizontal support on the electric pole is checked. It is confirmed that there is no serious crack or damage on the electric pole, and the electric pole can withstand the weight of the sliding wire clamp and the cable. Then the staff installs the double-layer multi-position sliding wire clamp 5 through the cross beam 1 and the U-shaped sheet metal frame 2 to the horizontal support of the electric pole, ensuring that the connection between the cross beam 1 and the U-shaped sheet metal frame 2 and the electric pole support is tight and not loose. At this time, it should be ensured that the installation position of the cross beam 1 matches the layout direction of the cable. Then the staff installs multiple parallel cables into the double-layer multi-position sliding wire clamp 5 according to their own position characteristics. At this time, the cables can be evenly distributed in the double-layer multi-position sliding wire clamp 5, and the spacing between each cable is appropriate, avoiding mutual friction or uneven support due to excessive density or looseness. After installation, check whether all fixed points are firm, and confirm whether the installation position of the cable is stable. The hydraulic damper 4 and the elastic support structure can effectively buffer the impact of external forces on the cable. Especially when the external environment changes such as wind and temperature change, the cable will sway. The hydraulic damper 4 can inhibit the sliding amplitude of the cable and the double-layer multi-position sliding wire clamp 5, avoiding violent swinging or excessive sliding of the cable.
