Technical Field

[0001] The invention relates to the technical field of insulator string production, and in particular to a power insulator manufacturing and assembling machine and an assembling process. Background Art

[0002] The assembly of insulator strings is an important part of the installation of power lines in power systems. It is mainly used to support the conductors and ensure the safe operation of the power system. The insulator string consists of multiple insulators connected in series, which are used to isolate the current from the conductor to the metal tower or supporting structure, while bearing the weight of the conductor and external forces such as wind load.

[0003] Nowadays, due to the special shape of insulator strings and their easy breakage, they are usually assembled one by one by manually moving them to the splicing table. This assembly method not only consumes a lot of manpower, but also easily leads to uneven quality during the assembly process. Therefore, in order to prevent the insulators from being knocked due to human fatigue, we propose a new type of assembly machine to improve assembly efficiency and reduce the labor intensity of assemblers.

Through the provided electric push rod two and the S-shaped clamping rod controlled by the torsion spring, before loading, it is only necessary to control the extension rod of the electric push rod two to extend, and the two clamped arc-shaped clamping blocks can be separated under the pull of the two steel ropes. When the insulator disk is placed above the bottom bracket slot, the extension rod of the electric push rod two can be retracted.

[0014] A manufacturing and assembly process for a power insulator comprises the following steps:

[0015] S1: During the loading stage, ensure that the pressing rod in the pressing mechanism is at the top initial position, and then wait for the reduction motor and the disc to operate to drag the sliding base plate and the clamping mechanism at its top to a position away from the ground rail, that is, at this time, the trapezoidal support block in the clamping mechanism is in a stationary state;

[0016] The extension rod of the second electric push rod is controlled to extend, and the two clamped arc-shaped clamping blocks are separated under the pull of the two steel wires. When the insulator disc is placed above the bottom bracket slot, the extension rod of the second electric push rod is retracted to fix the insulator disc to be assembled. Then, as the disc continues to rotate, the fixed insulator disc is pushed to the top of the longitudinal perforation;

[0017] S2: Once the electric telescopic rod in the pressing mechanism is started, the two pressing rods can be driven to move slowly downward until the insulator disc is pressed down as a whole until its ball head engages with the cap socket of the insulator disc on the ground rail; at this time, continue to press down and control the two arc-shaped clamping blocks to open until the edges of the bottom bracket slot lose their blocking ability; at this time, the locking pin shooting gun shoots out the fixing pin to lock the engaged part, and then the traction mechanism is controlled to drag the assembled insulator string one body length;

[0018] S3: When enough insulator disks are assembled, just slowly lift one end.

[0019] The beneficial effects of the present invention are:

[0020] 1. By setting a clamping mechanism that cooperates with the pressing mechanism, the clamping mechanism can be slid to a place away from the docking pressing station before docking, that is, when loading, until the single insulator disk to be assembled is clamped and then sent to the docking pressing station, that is, above the longitudinal perforation for docking and assembly. This not only improves the safety performance but also expands the space for the loading position, reduces the risk of collision and bumping of the insulator disk, and allows the loading stage to be replaced by a robot, reducing labor intensity and improving the accuracy of loading.

[0021] 2. By using the ball head connector, when pulling the assembled insulator string, you only need to connect the ball head connector to the ball head of the first insulator disk, and then start the rope winding mechanism to slowly pull it in the horizontal direction.

[0022] 3. By setting the buffer slide bar 1 on both sides of the insulator string near the top, the insulator string is further protected to prevent it from derailing during the dragging process. In addition, in the final lifting process, only one end of the insulator string needs to be fixed on the hook to slowly break through the clamping of the buffer slide bar 1. The unlifted part is still firmly fixed on the arc groove on the upper surface of the ground rail, making unloading convenient and safe. BRIEF DESCRIPTION OF THE DRAWINGS
