[0002] During the construction of substation projects, cable fixation is an important part of ensuring the safe and stable operation of the power system.

[0003] A Chinese patent with announcement number CN218733106U discloses a cable fixing device for power transmission and transformation projects, including a fixing box and two cover plates. Two mounting components are provided on the fixing box. Four cable arrangement holes are opened on both sides of the fixed box. A cable body is provided in two cable arrangement holes located on the same horizontal line. A guide wheel is provided in the cable arrangement hole, and the cable body is overlapped on the guide wheel; an adjustment component is provided in the fixing box, and connecting rods are hinged to the outside of the adjustment component through two pins. The bottom end of the connecting rod is hinged to the support plate through the pin, and the support plate is fixed to the support plate. A pushing component is provided at the bottom of the support plate.

[0004] However, a single cable of the device can only pass through a through hole fixedly opened on the side of the fixing box, and the spacing between the cables cannot be adjusted according to actual needs. Utility Model Content

[0005] The purpose of the utility model is to provide a cable fixing device for substation engineering construction in order to solve the above-mentioned technical problems, so as to achieve the effect of adjusting the distance between cables.

[0006] In view of this, the utility model provides a cable fixing device for substation engineering construction, including a mounting base plate and a fixing unit slidably arranged on the mounting base plate, the fixing unit including a sliding part slidably connected to the mounting base plate and a clamping part for fixing the cable.

[0007] In this technical solution, the fixing unit is slidably connected to the mounting seat plate, the fixing unit fixes the cable individually, and a plurality of fixing units are arranged on the mounting seat plate. The spacing between the cables can be changed by adjusting the position of the fixing unit on the mounting seat plate, thereby achieving the effect of arbitrarily adjusting the spacing between the cables.

[0008] In the above technical solution, further, a slide groove is provided along the length direction of the mounting seat plate, a sliding part of the fixed unit is slidably connected in the slide groove, the sliding part is a base, a positioning hole is connected to the top of the slide groove, the positioning holes are equidistantly arranged along the length direction of the slide groove, and mounting holes are arranged on the base corresponding to the positioning holes.

[0009] In this technical solution, the positioning holes and the mounting frame are both threaded holes. The fixing part of the fixing unit is slidably connected to the mounting seat plate. The sliding part is a base. The base slides in the slide groove to push the fixing unit to a suitable position. The mounting holes on the base and the positioning holes connecting the slide groove are aligned and fixed by bolts to ensure the connection strength and stability.

[0010] In the above technical solution, further, the clamping part includes clamping arms extending upward on both sides and bending toward each other, a slot for inserting the cable is formed between the free ends of the two clamping arms, a spring sheet is provided at the slot, and a placement cavity for placing the cable is formed between the two clamping arms.

[0011] In the present technical solution, the bayonet is slightly smaller than the width of the cable, and a spring sheet is further provided to prevent the cable from falling out after being fixed between the clamping arms on both sides.

[0012] In the above technical solution, further, one end of the spring sheet is fixedly connected to the inner wall of the clamp arm, and the other end extends toward the bayonet.

[0013] In this technical solution, there are two spring sheets, which are fixedly connected to the inner walls of the clamp arms. The cable squeezes the spring sheet from the bayonet, forcing the spring sheet to bend inward. After the cable is inserted, the spring sheet is reset and abuts against the cable, ensuring the stability of the cable and preventing the cable from falling out.

[0014] In the above technical solution, further, a filling layer is symmetrically arranged in the placement cavity, and the filling layer and the cable abutting surface are arc-surface structures.

[0016] In the above technical solution, further, a plurality of rolling grooves are arranged on the arc surface structure, the rolling grooves are arranged along the circumferential direction of the arc surface structure, and balls are arranged in the rolling grooves.

[0017] In the technical solution, at least two rows of rolling grooves and balls are provided, which can cooperate with the spring sheet to support the cable pressed into the installation cavity. The contact between the cable and the balls will produce rolling, reducing the wear on the cable surface.

[0018] In the above technical solution, further, a spring-pressing assembly is provided inside the clamp arm, and the spring-pressing assembly is respectively connected to the clamp arm and the spring sheet.

[0019] In the above technical solution, further, the spring-pressing assembly includes a shell fixedly connected to the inner wall of the clamp arm, a torsion spring is arranged in the shell, the first leg of the torsion spring passes through the shell and is fixedly connected to the inner wall of the clamp arm, and the second leg of the torsion spring is slidably connected to the extrusion groove arranged on the shell and is fixedly connected to the spring sheet.

[0020] In the present technical solution, there are two groups of spring-pressing assemblies, which are respectively arranged on the side walls of the clamp arms on both sides. Two groups of torsion springs are symmetrically arranged in the shell. The shell is horizontally arranged along the width direction of the clamp arms. The direction of the extrusion groove is the same as the direction of the extrusion deformation of the spring plate. When the spring sheet is squeezed, the spring sheet presses the second leg of the torsion spring to move along the extrusion groove. After the cable is pressed into the placement cavity, the second bracket is reset to drive the spring sheet to reset. The reset of the spring sheet is guaranteed by the setting of the spring-pressing assembly.

[0021] In the above technical solution, further, a rotating structure is provided at the free end of the clamping arm.

[0022] In the above technical solution, further, the rotating structure includes a notch arranged at the free end of the clamping arm, and a rotating shaft is arranged in the notch.

[0025] 1. The fixing unit is slidably connected to the mounting base plate. The fixing unit fixes the cables separately. A number of fixing units are arranged on the mounting base plate. The spacing between the cables can be changed by adjusting the position of the fixing unit on the mounting base plate, so as to achieve the effect of arbitrarily adjusting the spacing between the cables.

[0026] 2. There are two sets of spring-pressing components, which are respectively arranged on the side walls of the clamp arms on both sides. Two sets of torsion springs are symmetrically arranged in the shell. The shell is arranged horizontally along the width direction of the clamp arms. The direction of the extrusion groove is the same as the direction of the spring plate being extruded and deformed. When the spring sheet is extruded, the spring sheet presses the second leg of the torsion spring to move along the extrusion groove. After the cable is pressed into the placement cavity, the second bracket is reset to drive the spring sheet to reset. The spring sheet is reset by the setting of the spring-pressing component.

[0027] 3. The filling layer is symmetrically arranged in the placement cavity. The filling layer and the cable contact surface are arc-shaped structures. The filling layer is made of rubber and the cable contact surface is arc-shaped, which can support the inserted cables. There are several rolling grooves on the arc surface structure, which are arranged along the circumference of the arc surface structure. Balls are arranged in the rolling grooves, which can cooperate with the springs to support the cables pressed into the installation cavity. The contact between the cable and the ball will cause rolling, reducing the wear on the cable surface. BRIEF DESCRIPTION OF THE DRAWINGS
