Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for power grid operations, and in particular to a method of using a tension clamp holding device. Background Technology

[0002] When performing overheat detection and maintenance on the drain plates of compression-type tension clamps on power transmission lines, the equipment is typically mounted on a single transmission line, which can easily cause movement and inconvenience during operation. Therefore, a clamping device is needed to hold the corresponding compression-type tension clamp sleeve on the equipment, thereby fixing the spatial relative position of the equipment and the drain plate or limiting changes in their spatial relative position.

[0003] After the conductor is compressed, the sleeve of a compression-type tension clamp partially or completely forms a regular hexagon. Viewing the cross-section of the compression-type tension clamp sleeve from a perspective parallel to the horizontal and perpendicular to the horizontal, the angle between the base of the hexagon and the horizontal is arbitrary due to the forces exerted on it by other connected components. This means the hexagon may rotate arbitrarily around the intersection of its diagonals. This makes it difficult for conventional clamping devices to properly align the sleeve and clamp the tension clamp, thus creating difficulties in securing the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a method for using a clamping device for tension clamps, which is connected to working equipment and can clamp tension clamps at any angle.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0015] Furthermore, the cross-section of the guide section is convex, the cross-section of the slider is convex, and the size of the slider is adapted to the guide section.

[0016] In a preferred embodiment, the guide further includes a connecting plate, one end of the base plate is fixed to the connecting plate, and the connecting plate is mounted on the working equipment.

[0017] In a preferred embodiment, the driving mechanism is a motor, the output end of the motor is provided with a gear, the inner arc side or the outer arc side of the sliding member has teeth, and the gear and the teeth of the sliding member mesh.

[0018] In a preferred embodiment, the clamping member includes a telescopic cylinder and a locking block. The telescopic cylinder is disposed on the sliding member, and the locking block is disposed at the output end of the telescopic cylinder. The locking block has a slot, the shape of which is adapted to the shape of the tension clamp.

[0036] like Figure 1-3 As shown, this embodiment provides a method for using a clamping device for tension clamps. The clamping device includes: a guide 1, a sliding member 2, a clamping member 3, and a driving mechanism 4.

[0037] The guide member 1 is installed on the working equipment 6 and has a guide section. The axis of the guide section is an arc and its center is located on the axis of the tension clamp 5.

[0038] The slider 2 is disposed on the guide section and slides in cooperation with the guide 1;

[0039] The clamping member 3 is disposed on the sliding member 2, and one end is used to clamp the tension clamp 5. The axis of the clamping member 3 is perpendicular to the arc of the guide section.

[0040] The driving mechanism 4 is used to drive the slider 2 and the guide 1 to slide relative to each other.

[0041] The clamping device is used as follows: the driving mechanism 4 first drives the sliding member 2 to slide relative to the guide member 1, so that the clamping member 3 rotates around the outside of the tension clamp 5 to adjust the clamping angle. Then the clamping member 3 clamps and fixes the tension clamp 5. The driving mechanism 4 then drives the guide member 1 to slide relative to the sliding member 2, so that the guide member 1 drives the working equipment 6 to rotate around the tension clamp 5 to adjust the mounting angle of the working equipment 6.

[0042] like Figure 2-4 As shown, in a preferred embodiment, the guide member 1 includes a base plate 11 and two sets of rotating shafts 12. One set of rotating shafts 12 has at least one rotating shaft 12, and the other set of rotating shafts 12 has at least two rotating shafts 12. The two sets of rotating shafts 12 and the base plate 11 enclose the guide interval. The number of rotating shafts 12 in each set is adaptively adjusted according to the arc length of the guide interval. Preferably, the two sets of rotating shafts 12 are staggered.

[0043] The slider 2 is arc-shaped, and the curvature of its axis is consistent with the curvature of the axis of the guide zone. The slider 2 is guided to slide within the guide zone by the rotation of the rotating shaft 12, which can reduce friction and make the slider 2 slide more stably and smoothly.

[0044] like Figure 3 As shown, in a preferred embodiment, the sliding member 2 includes a slider 21, a transmission gear block 22, and a connecting block 23 arranged in parallel. The slider 21, the transmission gear block 22, and the connecting block 23 are all arc-shaped, with the curvature of their axes matching that of the guide section's axis, and the centers of the arcs all located on the axis of the tension clamp 5. The slider 21 is located within the guide section and slides in cooperation with the rotating shaft 12. The transmission gear block 22 is driven by the driving mechanism 4, and the connecting block 23 is connected to the clamping member 3.

[0045] Furthermore, when the clamping member 3 is not clamping the tension clamp 5, the sliding member 2 is not subjected to any other external force. When the driving mechanism 4 drives the sliding member 2, the guide member 1 remains stationary, and the sliding member 2 slides. When the clamping member 3 is clamping the tension clamp 5, under the action of the clamping member 3 and the tension clamp 5, when the driving mechanism 4 drives the sliding member 2, the sliding member 2 remains stationary, and the guide member 1 slides.

[0046] like Figure 5 As shown, the cross-section of the rotating shaft 12 is convex, making the cross-section of the guide section also convex, wider on the side closer to the base plate 11 and narrower on the side farther from the base plate 11; the cross-section of the slider 21 is convex, its size is adapted to the guide section, and the direction is the same. In this way, the two sets of rotating shafts 12 limit the slider 21 within the guide section, so that the slider 21 does not deviate in the vertical and horizontal directions.

[0047] like Figure 3-4 As shown, in a preferred embodiment, the guide 1 further includes a connecting plate 13, one end of the base plate 11 is fixed on the connecting plate 13, and the connecting plate 13 is mounted on the working equipment 6.

[0048] like Figure 3As shown, in a preferred embodiment, the driving mechanism 4 is a motor 41, and the output end of the motor 41 is provided with a gear 42. The inner or outer arc side of the transmission gear block 22 has teeth, and the gear 42 meshes with the transmission gear block 22. In this embodiment, the teeth are located on the outer arc side of the transmission gear block 22. Through the engagement of the gear 42, the guide 1 and the sliding member 2 remain relatively fixed in the unpowered state, so that after the clamping member 3 clamps and fixes the tension clamp 5, the working device 6 remains fixed, improving stability.

[0049] like Figure 2-3 As shown, in a preferred embodiment, the clamping member 3 includes a telescopic cylinder 31 and a locking block 32. The telescopic cylinder 31 is disposed on the connecting block 23, and the locking block 32 is disposed at the output end of the telescopic cylinder 31. The locking block 32 has a slot, the shape of which is adapted to the shape of the tension clamp 5. The locking block 32 fits the tension clamp 5 through the slot, so that the clamping device and the tension clamp 5 are circumferentially fixed. The driving direction of the telescopic cylinder 31 is perpendicular to the arc of the guide section, so that the slot of the locking block 32 is always aligned with the tension clamp 5.

[0050] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
