Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insulator joints, in particular to a segmented insulator joint clamp. Background Art
[0002] A segment insulator is an insulating device used to electrically segment the catenary. Under normal circumstances, the pantograph slides through the section while energized. If a fault occurs in a catenary section or a power outage occurs due to construction, the disconnector at the segment insulator disconnects power to that section of the catenary while maintaining normal power supply to the remaining sections. If two sections of the catenary system are powered separately, and a power failure occurs on one section, the disconnector can be closed, allowing the power to be supplied from a single source, thereby improving the reliability and flexibility of the catenary operation.
[0003] Contact wire joint clamps are often used at the connection position between the segmented insulator and the live part of the electrified railway contact network. The contact wire joint clamps are generally composed of two identical clamping plate bodies with hook grooves on the upper and lower parts, bolts and nuts.
[0004] Most of the current insulator joint clamps require the use of a wrench or other tools to assist the joint clamp in clamping the insulator, which is cumbersome to install and increases the workload of workers. In addition, the spacing between two identical clamps is limited and cannot be adjusted according to the size of the insulator joint, making it inconvenient to fix insulator joints of different sizes, reducing its applicability.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0039] Reference Figures 1-4A segmented insulator joint clamp includes a clamp base plate 1, the top surface of which is provided with a placement slot 101. A clamp top plate 2 is hingedly connected to the end of the clamp base plate 1. Screws 3 are rotatably connected to opposite sides of the clamp top plate 2. A clamping plate 4 is mounted at the bottom of the screw 3. A cushioning pad 5 is bonded to the inner wall of the clamping plate 4. The cushioning pad 5 protects the clamped object from damage while also providing a certain degree of comfort and stability. The clamp base 1 and the clamp top plate 2 are also provided with a fixed member and a rotating member. The fixed member is used to reinforce the installation of the clamp base plate 1 and the clamp top plate 2, and the rotating member is used to drive the screw 3 to rotate.
[0040] Furthermore, two placement slots 101 are symmetrically provided, and the placement slots 101 are arranged in a semi-arc shape.
[0041] Furthermore, the fixing part includes a fixing block 21, a support rod 22, a sleeve 23, a threaded rod 24 and a nut 27. There are two fixing blocks 21. The two fixing blocks 21 serve as the basis for support and rotation connection to ensure the stability and reliability of the entire fixing part. The fixing blocks 21 are fixed to the opposite sides of the bottom clamp plate 1, the support rod 22 is rotatably connected between the two fixing blocks 21, the sleeve 23 is fixed to the support rod 22, the threaded rod 24 is fixed to the sleeve 23, and the nut 27 is threadedly connected to the screw rod 3. The nut 27 forms a tight threaded connection with the threaded rod 24, and the clamping force of the clamp can be adjusted and fixed by rotating the nut 27.
[0042] Furthermore, the fixing member also includes a concave block 25 and a snap-in groove 26. The concave block 25 is fixed to the top clamp plate 2 of the wire clamp, and the concave block 25 provides additional support and fixing points. The design of the concave block 25 not only enhances the overall structural strength of the wire clamp, but also provides a basis for the opening of the snap-in groove 26. The snap-in groove 26 is opened on the top surface of the concave block 25, and the inner diameter of the snap-in groove 26 matches the outer diameter of the nut 27. This design allows the nut 27 to be effectively clamped and fixed during the rotation and adjustment process, preventing it from accidentally loosening or falling off. At the same time, the snap-in groove 26 also facilitates the quick installation and removal of the nut 27.
[0043] Furthermore, the rotating member includes a support shaft 31, a rotating shaft 32, a rocker 33, a driving gear 34, a support shaft 36, and a driven gear 35. The support shaft 31 is fixed to the top surface of the top clamp plate 2, ensuring that the driving gear 34 and the rotating shaft 32 can rotate stably, while providing necessary support and guidance. The rotating shaft 32 is rotatably connected to the top surface of the top clamp plate 2. The rotating shaft 32 is placed in the support shaft 31 and rotates, allowing the rotating shaft 32 to rotate smoothly under the guidance of the support shaft 31. The rocker 33 is fixed to the rotating shaft 32, and the driving gear 34 is rotatably connected to the support shaft 31. The interior of the driving gear 34 is provided with an external thread that matches the thread of the screw 3. The support shaft 36 is fixed on opposite sides of the top surface of the top clamp plate 2. The support shaft 36 serves as the installation base for the driven gear 35, ensuring that the driven gear 35 can rotate stably and providing necessary support and guidance. The driven gear 35 is rotatably connected to the support shaft 36 . Two driving gears 34 are provided. The two driving gears 34 mesh with both sides of the driven gear 35 .
[0044] Furthermore, a cavity is provided within the top plate 2 of the wire clamp to facilitate the rotation of the screw 3. This cavity facilitates the rotation of the screw 3 by providing sufficient space within which the screw 3 can rotate freely. Since the screw 3 typically requires a threaded connection to secure or adjust the wire clamp, the cavity design reduces friction and resistance during the rotation of the screw 3, making operation smoother and more efficient.
[0045] The functional principle of this utility model can be explained through the following operation modes:
[0046] When reinforcing the insulator joint, first install the insulator joint in the placement groove 101 in the wire clamp bottom plate 1, then flip the wire clamp top plate 2 so that the wire clamp top plate 2 is on the same horizontal plane as the wire clamp bottom plate 1, then flip the screw 3 so that it is driven by force to drive the sleeve 23 to rotate around the support rod 22, so that the screw 3 is immediately rotated into the concave block 25, and when the screw 3 is rotated to the vertical state, the nut 27 is put on the screw 3, and the nut 27 is rotated and slid down along the screw groove of the screw 3, and stops rotating when the nut 27 slides to the clamping groove 26 on the top surface of the concave block 25, so that the wire clamp bottom plate 1 and the wire clamp top plate 2 are stably installed, making installation convenient, improving installation efficiency and reducing the workload of workers.
[0047] After installation, the rocker 33 is manually rotated to drive the rotating shaft 32 placed in the support shaft 31 to rotate. When the rotating shaft 32 rotates, the driving gear 34 on its outside rotates along the support shaft 31 and engages with the driven gear 35. The driven gear 35 is forced to rotate and engages with the screw 3 in the middle. The screw 3 is forced to drive the clamping plate 4 to descend through the action of the thread to clamp and fix the insulator joint. By adjusting the clamping height of the clamping plate 4, it can fix insulator joints of different specifications and sizes, thereby improving its applicability.
[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
