[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0029] like Figure 1 As shown, the utility model provides a conductive rod clamp for GIS pipe mother, comprising: a fixed support plate 1, a handle 2, a central connecting rod 3, a support frame 4, a semicircular clamp 5, a four-bar linkage 6, and a latch 7;
[0030] The handle 2 and the central connecting rod 3 are vertically assembled along the center of the fixed support plate 1, and the handle 2 and the central connecting rod 3 are fixed, wherein the central connecting rod 3 can move vertically along the fixed track in the middle of the fixed support plate 1;
[0031] The support frame 4 is rigidly connected to the fixed support plate 1, and the three end points of the bottom T zone of the support frame 4 are hinged to a semicircular clamp 5. It should be noted that Figure 1 The middle dotted line is the T zone;
[0032] The four-bar linkage 6 is assembled at the bottom of the support frame 4 and is mechanically connected to the central link 3 via a latch 7;
[0033] Each end point of the four-bar linkage 6 is also hinged to one of the semicircular clamps 5 .
[0034] It should be noted that the support frame 4 in this embodiment can be a triangular support frame or a bracket that can carry a three-phase busbar barrel.
[0035] The utility model provides a conductive rod telescopic clamp structure for GIS pipe mother:
[0036] 1. The principle of the central connecting rod's telescopic movement drives the clamps to open and close, which can achieve simultaneous clamping of the conductive rods by the connecting rod's movement. At the same time, the connecting rod drives three clamps distributed in an "equilateral triangle" to grasp three conductive rods at a time.
[0037] 2. Specially designed conductive rod fixture and gripping method: The center connecting rod drives the semicircular fixture. During the extension and retraction of the connecting rod, the fixture rotates and closes along the center of the conductive rod, which can effectively protect the surface of the workpiece.
[0038] Furthermore, the central connecting rod 3 is a screw.
[0039] By adopting a screw-type central connecting rod 3, high docking accuracy can be achieved, especially for long conductive rods assembled in long busbar barrels. The positioning of the clamp is controlled according to the moving position of the screw, and the assembly accuracy is high. The distance requirement of the three-phase conductive rods can be effectively guaranteed, and the deviation can be controlled within ±1mm, meeting the occasions with high precision requirements.
[0040] Furthermore, the handle 2 is a sliding handle.
[0041] It should be noted that the principle design of this device adopts a sliding handle telescopic type, which is simple to operate and easy to assemble and disassemble. It only needs to be assembled on the hand hole to conveniently clamp the conductive rod. After use, pull the center link 3 to drive the four-bar linkage 6 to contract, and it can be easily taken out.
[0042] Furthermore, the three semicircular clamps 5 are assembled at the bottom T-zone of the support frame 4 , and the centers of the three semicircular clamps 5 form an equilateral triangle.
[0043] It should be noted that the centers of the three semicircular clamps 5 form an equilateral triangle. Based on the requirements of stable use, high positioning accuracy and the conditions of use of the device, the entire device is fixed to the upper hand hole flange through a support plate, and the working principle of the three clamps distributed in an "equilateral triangle" is driven by the central connecting rod 3.
[0044] Furthermore, the four-bar linkage 6 is assembled at the bottom of the support frame 4 and is bilaterally symmetrical.
[0045] Furthermore, the lengths of the four bars of the four-bar linkage 6 are all the same, or are the same in pairs.
[0046] It should be noted that the length of the four-link rod can be set according to the size of the assembled busbar tube, so as to achieve a flexible structure and be applicable to different occasions.
[0047] Furthermore, if Figure 4 As shown, the fixed support plate 1 is fixedly connected to the busbar barrel housing through a flange.
[0048] It should be noted that the device is easy to operate. It only needs to be assembled on the hand hole to conveniently clamp the conductive rod. After use, the handle 2 fixed on the fixed support plate 1 is used to lift the central connecting rod 3 to drive the four-bar linkage 6 to contract, so that it can be easily taken out.
[0049] Figure 2 and Figure 3 Schematic diagrams of the clamping device in the clamped state and the open state are respectively given. It can be seen that as the central connecting rod 3 moves up and down, the semicircular clamp 5 opens and closes in an orderly manner.
[0050] Furthermore, if Figure 3 As shown, when the triangular support frame 4 is stationary and the central connecting rod 3 moves upward with the handle 2, one of the three semicircular clamps 5 rotates counterclockwise around the center, one semicircular clamp 5 rotates clockwise around the center, and one semicircular clamp 5 opens symmetrically at the position where it is fixed with the central connecting rod 3. At this time, the conductive rod clamp for the GIS pipe mother is in an open state.
[0051] Furthermore, if Figure 2 As shown, when the triangular support frame 4 is stationary and the central connecting rod 3 moves downward with the handle 2, one of the three semicircular clamps 5 rotates counterclockwise around the center, one semicircular clamp 5 rotates clockwise around the center, and one semicircular clamp 5 is closed symmetrically at the position where it is fixed with the central connecting rod 3. At this time, the conductive rod clamp for the GIS pipe mother is in a locked state.
[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
