Description

Technical Field

[0001] The utility model relates to the technical field of power protection, in particular to an electric wrench fixing device for interphase spacer bars. Background Art

[0002] Spacers are devices installed on split conductors to fix the spacing between each split conductor to prevent the conductors from whipping each other and suppress breeze vibration and sub-spacing oscillation. The existing spacers are installed by drone hoisting.

[0003] The existing spacer rods use an electric wrench to provide a power source to fix the cable. However, after clamping, the electric wrench needs to be separated from the spacer rod to achieve reuse. At the same time, during the transmission clamping process, the concentricity of the electric wrench needs to be ensured to prevent the electric wrench from shaking, which makes it impossible to drive the clamping assembly to clamp and fix the cable. Utility Model Content

A fixing plate is fixed to the front end of each slider, and the fixing plate is fixedly connected to the electric wrench. Two symmetrical tension springs are fixedly connected to the fixing plate, and the lower ends of the tension springs are fixedly connected to the lower end of the fixing frame. The left and right ends of the fixing frame are provided with symmetrically arranged springs, and the fixing assembly is slidably connected to the fixing frame through the springs.

[0007] The fixing assembly includes an electric telescopic rod, the front and rear ends of the electric telescopic rod are connected to clamping blocks, the clamping blocks are threadedly connected to clamping bolts, the clamping bolts are rotatably connected to the connecting blocks, and the clamping blocks are fixed with protrusions corresponding to springs. The upper end of the connecting block is fixed with the electric telescopic rod, and the upper end of the electric telescopic rod is fixed with an H-shaped adjustment block, and the adjustment block corresponds to the forward and reverse push blocks of the electric wrench.

[0008] Preferably, four electromagnets arranged in a rectangular shape are fixed to the lower end of the fixing frame, a slide rod is provided on the electromagnet, and a spring is provided at one end of the slide rod close to the fixing frame.

[0009] Preferably, two symmetrically arranged hollow connecting tubes are fixed to the upper end of the connecting frame, and the sliding rod is inserted into the connecting tubes.

[0013] 1. Through the cooperation of the slide rail, slider and tension spring, when the electric wrench is rotating and transmitting, since the bolt is threadedly connected to the fixed block, when the bolt rotates, the bolt will move down. At this time, the tension spring will pull the fixed plate down, and the slider will slide up and down on the slide rail to ensure effective transmission between the electric wrench and the bolt, and prevent the bolt from being separated from the electric wrench, resulting in the clamping block being unable to rotate to clamp the cable. The fixed frame and the fixed block are connected through the cooperation of the electromagnet, slide rod, spring and connecting tube. When it is necessary to separate them, the electromagnet is controlled to work and the slide rod is withdrawn. At this time, the spring is compressed, and the slide rod is pulled out of the connecting tube, releasing the connection between the fixed frame and the fixed block, thereby realizing the separation of the fixed block and the fixed frame.

[0014] 2. By rotating the clamping bolt to move the clamping block, the electric wrench is clamped and fixed, which further fixes the electric wrench to prevent it from shaking during operation and affecting the concentricity. The protrusion, clamping bolt and spring are engaged and slid, so that the fixed component can only move up and down. The electric telescopic rod pushes the adjustment block up and down to control the forward and reverse rotation of the electric wrench, thereby adjusting the forward and reverse rotation of the electric wrench.

[0023] See also Figure 3 、 Figure 4 and Figure 5The front end of the fixing frame 4 is fixed with two symmetrical slide rails 41, and the slide rails 41 are slidably connected with sliders 42. The front ends of the sliders 42 are fixed with fixed plates 43, and the fixed plates 43 are fixedly connected to the electric wrench 5. Two symmetrical tension springs 44 are fixedly connected to the fixing plate 43, and the lower ends of the tension springs 44 are fixedly connected to the lower ends of the fixing frame 4. Through the cooperation of the slide rails 41, the sliders 42 and the tension springs 44, when the electric wrench 5 is rotated and transmitted, since the bolt 52 is threadedly connected to the fixing block 3, when the bolt 52 rotates, the bolt 52 will move down, at this time the tension spring 44 will pull the fixing plate 43 down, and the slider 42 will slide up and down on the slide rails 41, ensuring the effective transmission of the electric wrench 5 and the bolt 52, preventing the bolt 52 from disengaging from the electric wrench 5, resulting in the clamping block 9 being unable to rotate to clamp the cable. The upper and lower ends of the bracket 4 are both provided with symmetrically arranged springs 47, one end of the spring 47 is fixedly connected to the electromagnet 45, and the other end of the spring 47 is fixedly connected to the slide bar 46.

When it needs to be disengaged, the electromagnet 45 is controlled to work and the slide bar 46 is withdrawn. At this time, the spring 47 is compressed, and the slide bar 46 is pulled out of the connecting tube 61, thereby releasing the connection between the fixing frame 4 and the fixing block 3, thereby realizing the separation of the fixing block 3 from the fixing frame 4.

[0024] See also Figure 3 、 Figure 4 and Figure 5 The fixing assembly 7 includes an electric telescopic rod 75, the front and rear ends of which are connected to a clamping block 72, the clamping block 72 is threadedly connected to a clamping bolt 73, the clamping bolt 73 is rotatably connected to the connecting block 71, and the clamping block 72 is fixed with a protrusion 74 corresponding to the spring 47, the upper end of the connecting block 71 is fixed with the electric telescopic rod 75, and the upper end of the electric telescopic rod 75 is fixed with an H-shaped adjustment block 76, the adjustment block 76 is aligned with the positive position of the electric wrench 5 Corresponding to the reverse push block, the clamping block 72 is moved by rotating the clamping bolt 73, thereby clamping and fixing the electric wrench 5, further fixing the electric wrench 5, and preventing the electric wrench 5 from shaking and affecting the concentricity during operation. The protrusion 74 and the clamping bolt 73 are engaged and slid with the spring 47, so that the fixing assembly 7 can only move up and down. The electric telescopic rod 75 pushes the adjustment block 76 to move up and down, and the electric wrench 5 can be controlled to rotate forward and reverse, thereby adjusting the forward and reverse rotation of the electric wrench 5.
