Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical safety technology, and more specifically to a fixing device for loose electrical porcelain insulators. Background Technology
[0002] In power distribution lines, drop-out fuses are critical overload and short-circuit protection devices, typically installed on iron crossarms via porcelain insulators. A typical installation structure involves a pre-drilled mounting hole in the center of the porcelain insulator. One end of a metal connector is secured to the hole using adhesive, while the other end is rigidly connected to the crossarm. While this cement-based bonding process provides sufficient mechanical strength initially, long-term outdoor operation exposes the adhesive to various factors such as temperature cycling, rain erosion, mechanical vibration, and material aging. This can cause the adhesive to crack, powder, or even fail, reducing the bond strength between the connector and the insulator and leading to loosening of the insulator. If these hazards are not detected and addressed promptly, they can cause electrical accidents such as equipment tilting, lead wire breakage, or even insulator detachment, seriously threatening the safe and stable operation of the power line.
[0003] Therefore, during regular power line inspections, once loose insulators are detected, rapid and effective temporary reinforcement measures must be taken. However, existing devices for securing loose insulators generally suffer from poor adaptability in practical applications, making it difficult to meet complex on-site installation conditions. Specifically, this manifests as insufficient adaptability to installation angles: different types of insulators, after installation, have an angle of inclination between the insulator axis and the crossarm due to line routing and installation requirements. The angle of inclination varies between different insulators and crossarms. Existing fixing devices are mostly rigid structures, unable to flexibly adapt to these changing angles, making it difficult to accurately secure them to the loose insulators or apply effective tightening force.
[0004] In conclusion, developing a temporary fixing device that can flexibly adjust its angle to adapt to different porcelain insulator installation angles is of urgent practical need for improving the efficiency of power emergency maintenance and ensuring the safe operation of power lines. Summary of the Invention
[0005] To address the shortcomings of the aforementioned technology, this invention provides a fixing device for loose electrical porcelain insulators, which can be adapted to insulators with different installation angles and can better fix loose electrical porcelain insulators.
[0006] This invention discloses a fixing device for loose electrical porcelain insulators, including a fixing mechanism, a hooking mechanism, and a connecting mechanism connecting the fixing mechanism and the hooking mechanism. The hooking mechanism includes a fixing base, a supporting shell, a hooking assembly, and a tilt adjustment device. The fixing base is fixedly connected to the fixing mechanism through the connecting mechanism. The front end of the supporting shell is hinged to the fixing base, and the hooking assembly is provided at the front end of the supporting shell. The tilt adjustment device is provided between the rear end of the supporting shell and the fixing base. The tilt adjustment device includes an adjusting bolt, a pushing member, and a guide member. The rear end of the fixing base is vertically provided with a threaded through hole, and a downward-facing trumpet-shaped guide shell is provided on the lower side of the threaded through hole. The adjusting bolt is screwed into the threaded through hole. The pushing member is provided at the top end of the adjusting bolt, and the pushing member and the top end of the adjusting bolt are rotatably connected, and the two can rotate relative to each other around the central axis of the adjusting bolt. The guide member is provided on the lower side of the rear end of the supporting shell. The pushing member is slidably provided on the guide member.
[0007] When using a special tool to turn the adjusting bolt, the special tool can be as follows: an electric screwdriver is installed on the upper end of the link bar, and the control button of the electric screwdriver is set at the lower end of the link bar. The electric screwdriver is controlled to rotate by the control button to drive the adjusting bolt, so that the jacking component moves vertically. The jacking component, through its sliding on the guide, converts its own vertical displacement into pushing or pulling on the rear end of the support housing, thereby causing the support housing to rotate around its front hinge point, realizing the adjustment of the pitch angle. This allows the hook assembly to be accurately aligned with the axis of the porcelain bottle, effectively compensating for the inherent tilt that exists during the installation of the porcelain bottle.
[0008] To accommodate different distances between porcelain bottles and the crossbar, the hook assembly includes a telescopic rod and a hook. The telescopic rod is slidably mounted within the support housing via a linear drive device. The front end of the telescopic rod extends from an opening at the front of the support housing, and a hook for supporting the porcelain bottle is provided at the front end. The linear drive device includes a right-angle adapter drive, a screw, and a nut. An adjustment port is located on the lower rear side of the support housing, and a downward-facing second-order flared guide housing is located below the adjustment port. A right-angle adapter drive is located inside the rear end of the support housing, with its input end located at the adjustment port. The output end of the angle adapter drive faces the telescopic rod and is equipped with a screw. The direction of the screw is parallel to the extension direction of the telescopic rod. The telescopic rod is hollow inside, and a mounting hole is provided at the rear end of the telescopic rod. A nut is installed in the mounting hole, and the screw and nut are screwed together. When the input end of the right-angle adapter drive is driven by the above-mentioned special tool, the output end will drive the screw to rotate, thereby cooperating with the nut to extend or retract the telescopic rod. This allows for precise control of the extension length of the telescopic rod, enabling the hook to accurately extend into and support the skirt of the porcelain bottle, thus providing a stable and reliable upward support force to counteract its downward tendency.
[0009] To ensure the device's fixing mechanism can precisely adapt to crossarms of different cross-sectional shapes (such as angle steel and rectangular tubes) and sizes, the fixing mechanism includes a first base, a second base, a height adjustment component, a third base, and a locking arm. The first base is horizontally positioned, and the second base is vertically positioned and slidably mounted below the first base, secured by a locking structure. The height adjustment component is slidably mounted on the second base and secured by a locking structure. The third base is horizontally positioned and slidably mounted on the height adjustment component and secured by a locking structure. The locking arm is horizontally positioned and includes a first locking arm hinged to the first base and a second locking arm slidably mounted on the first locking arm. The first and second locking arms are secured by a locking structure, and the second base, height adjustment component, third base, and second locking arm allow for flexible adjustment and locking. This allows the device's fixing mechanism to precisely adapt to crossarms of different cross-sectional shapes (such as angle steel and rectangular tubes) and different specifications. A first torsion spring is provided at the hinge point between the first locking arm and the first base, giving the locking arm a downward pressing tendency. The end of the second locking arm is provided with a fastening part, and the third base is provided with a fastened part that cooperates with the fastening part. A locking rod is also hinged to the first locking arm, and a buckle is provided on the first base. The end of the locking rod is bent and fastened to the buckle, and a second torsion spring is provided at the hinge point between the locking rod and the first locking arm to keep the locking rod in a fastened state. When the device is not installed, its locking rod is tightly fastened to the buckle under the action of the second torsion spring, at which time the locking arm is raised and held in place. In the open state, under the preload of the first torsion spring, the locking arm tends to press down automatically. A trigger mechanism is located on the first base corresponding to the bent portion of the locking rod, used to drive the locking rod to disengage from the latch. The trigger point of the trigger mechanism is located on the lower side of the first base. The upper part of the second base, near the locking arm, has a horizontal slot for inserting one side of the angle steel. When the operator inserts the link into the insertion hole on the lower side of the fixing base to latch the device onto the target crossarm, the crossarm naturally presses against the trigger point located on the lower side of the first base. This pressure drives the trigger mechanism to move, thereby lifting the bent portion of the locking rod and disengaging it from the latch. Once the locking rod disengages, the previously restrained locking arm quickly rotates downwards and closes under the action of the first torsion spring. The latching part at the end of the second locking arm then automatically latches with the latched part on the third base, instantly and firmly "locking" the device onto the crossarm. The hook mechanism reliably supports loose electrical insulators.
[0010] To facilitate precise control of the displacement of each adjusting component of the fixing mechanism, one surface of the No. 1, No. 2, and No. 3 bases and the locking arm is provided with graduations for accommodating angle steel, while the other surface is provided with graduations for accommodating rectangular tubes. This design allows operators to quickly and accurately adjust the crossarms for different types.
[0011] To facilitate adjustment of the horizontal distance, left-right position, and hook orientation between the hook holding mechanism and the fixing mechanism, the connecting mechanism includes a first mounting base and a second mounting base fixed to a first base and a fixing base, respectively, and an adjusting rod connecting the two. The adjusting rod has multiple sets of first positioning holes spaced along its length. Both the first and second mounting bases have horizontal through holes for the adjusting rod to pass through, and vertical locking threaded holes above the through holes. Both ends of the adjusting rod pass through the horizontal through holes of the first and second mounting bases, respectively. Inside, the first positioning hole is aligned with the locking threaded holes on mounting bases one and two, and bolts are screwed in to secure it. By selecting different first positioning holes, multiple adjustment positions of the connection distance and left and right position can be achieved. The end of the telescopic rod is provided with a plug interface, and the telescopic rod is provided with a first pin hole that passes through the plug interface. One end of the hook is provided with a plug part, which is inserted into the plug interface. A second pin hole is provided on the plug part corresponding to the position of the first pin hole. The first pin hole and the second pin hole are aligned and fixed by bolts and nuts. The detachable nature of the hook makes it easy to adjust the orientation of the hook.
[0012] To facilitate adjustment of the hook's position in the height direction, an adjusting rod is provided at the front end of the telescopic rod. The adjusting rod has second positioning holes spaced along its length. One end of the hook has a slot into which the adjusting rod is inserted. A through hole corresponding to the second positioning hole is provided on the hook, and the hook is detachably connected via bolts and nuts. The adjusting rod has graduations along its length. By providing an adjusting rod with multiple sets of second positioning holes at the front end of the telescopic rod, and having the hook fitted onto the outside of the adjusting rod through the slot, the hook's height can be adjusted. When the hook reaches the desired height, a bolt is passed through the through hole on the hook and screwed into the corresponding second positioning hole for locking and fixing, thus precisely and flexibly adjusting and fixing the vertical position of the hook.
[0013] The present invention provides a fixing device for loose electrical porcelain insulators. Its advantages are that when different electrical porcelain insulators become loose, the fixing device described in the present invention can be adapted to different angles, distances, and crossarms. The locking arm structure can quickly and effectively fix the insulators, significantly improving the ease of operation and installation efficiency. It greatly simplifies the operation process, reduces the time spent working at heights and the workload of personnel, and is particularly suitable for urgent power emergency maintenance situations.
