Technical Field

[0001] The utility model belongs to the technical field of power equipment, and particularly relates to a multifunctional insulator replacement fixture. Background Art

[0002] Insulators used in high-voltage transmission lines are damaged easily due to long-term exposure to the open air and being affected by lightning and rain. To avoid affecting power consumption safety, an insulator replacement fixture is needed for timely replacement. Since there are many types of insulators, traditional replacement fixtures can only replace insulators of a certain type, and their lack of universality leads to low efficiency in insulator replacement.

[0003] In view of this situation, the multifunctional insulator replacement fixture is designed. Summary of the Utility Model

[0005] The utility model provides the following technical solutions:

[0006] A multifunctional insulator replacement fixture includes a front clamp, a rear clamp, an adjusting chuck, a pin shaft and a T-shaped locking pin shaft. The middle parts of the front clamp and the rear clamp are semi-circular structures. Connecting parts are provided on both sides of the semi-circular structure of the front clamp, and annular buckles are formed on the connecting parts. An annular buckle is also provided on one side of the semi-circular structure of the rear clamp, and a concave buckle is provided on the other side. The pin shaft passes through the annular buckle and the concave buckle to connect the front clamp and the rear clamp. The adjusting chuck is fixed on the semi-circular structures of the front clamp and the rear clamp through mounting holes. A pin shaft hole is formed in the upper part of the concave buckle, and the T-shaped locking pin shaft passes through the pin shaft hole to fix the pin shaft. Anti-disengagement structures are provided on one side of the lower parts of the pin shaft and the T-shaped locking pin shaft.

The opposite to the forward direction is the rear. Similarly, up, down, left, and right are all referred to the forward direction of the roadheader-anchor-loader and will not be elaborated hereinafter.

[0032] Embodiment: A multifunctional insulator replacement fixture, the structure is referred to Figures 1-6 as shown, including a front clamp 1, a rear clamp 2, an adjusting chuck 3, a pin shaft 6 and a T-shaped locking pin shaft 4. The middle parts of the front clamp 1 and the rear clamp 2 are semi-circular structures; both sides of the semi-circular structure of the front clamp 1 are provided with connecting parts 10, and ring buckles 12 are arranged on the connecting parts 10; one side of the semi-circular structure of the rear clamp 2 is also provided with a ring buckle 12, and the other side is provided with a concave buckle 13; the pin shaft 6 passes through the ring buckle 12 and the concave buckle 13 to connect the front clamp 1 and the rear clamp 2;

[0033] During specific use, the pin shaft 6 passes through the ring buckle 12 to connect one end of the front clamp 1 and the rear clamp 2. At this time, the ring buckle 12 can rotate around the pin shaft 6; the ring buckle 12 at the other end of the front clamp 1 is docked with the concave buckle 13 of the rear clamp 2, and the front clamp 1 and the rear clamp 2 are fixed at the other end by using the pin shaft 6 and the T-shaped locking pin shaft 4; specifically, a pin shaft hole 14 is opened at the upper part of the concave buckle 13, and the T-shaped locking pin shaft 4 passes through the pin shaft hole 14 to fix the pin shaft 6, referring to Figure 9 as shown;

[0034] Referring toFigure 1 As shown, the adjusting chuck 3 is fixed on the semi-circular structures of the front chuck 1 and the rear chuck 2 through the mounting holes 11;

[0035] Referring to Figure 7 and Figure 8 As shown, a plurality of positioning holes 15 are provided on the adjusting chuck 3, and the sizes of the positioning holes 15 match the mounting holes 11. The chuck locking pin shaft 5 passes through the positioning holes 15 to fix the adjusting chuck 3;

[0036] During specific use, by adjusting different positioning holes 15 of the adjusting chuck 3, the clamping diameter of the fixture is adjusted to adapt to insulators of corresponding models.
