Technical Field

[0001] The invention relates to the technical field of parallel groove wire clamp installation, in particular to an installation tool for the parallel groove wire clamp. Background Art

[0002] Parallel groove wire clamps are mainly used in power line projects. Parallel groove wire clamps are used to connect small and medium-section aluminum stranded wires or steel-core aluminum stranded wires and steel stranded wires of overhead lightning conductors at positions that do not bear tension, in order to transfer electrical loads. They are widely used, such as jumpers on non-straight poles and towers, T-connections at non-load-bearing connections in power systems, branch lines, down conductors for electrical equipment such as switches and transformers, and grounding down conductors for lightning conductors.

[0003] The parallel groove wire clamp is used for connecting aluminum stranded wire or steel core aluminum stranded wire of small and medium cross-section and steel stranded wire of overhead lightning arrester at the position where it does not bear tension, and is also used for jumper connection of non-linear pole tower. The power engineering material connecting wires is mainly used for power line engineering. It is mainly achieved by overlapping a new sub-wire on the old busbar in the air, and the parallel groove wire clamp is used to achieve conduction, and the new and old cables are exposed to metal wires. There are various existing parallel groove wire clamp installation tools, which are based on manual operation, and some manufacturers' products are electric. However, they have a common disadvantage, that is, they cannot achieve modular production. When the models of different manufacturers are different, the product parts cannot be interchanged, and the applicability is low. In addition, at present, whether it is a manual parallel groove wire clamp installation tool or an electric parallel groove wire clamp installation tool, there are only single parallel groove wire clamp installation tools, and there are no double parallel groove wire clamp installation tools.

[0006] As a further improvement of the present invention, the lower left card plate and the lower middle card plate are provided with through holes for connecting the upper locking frame.

[0007] As a further improvement of the present invention, a slide groove for limiting the upper locking frame and the lower locking frame is provided on the fixing seat.

[0008] As a further improvement of the present invention, the lower left rack and the lower right rack are symmetrically arranged with the lower middle clamping plate as the center.

The left end and the middle of the lower locking frame 3 are respectively provided with a lower left card plate 6 and a lower middle card plate 7. The upper locking frame 2 penetrates and slides to connect the lower left card plate 6 and the lower middle card plate 7. The fixed seat 1 between the upper locking frame 2 and the lower locking frame 3 is provided with a left locking gear 8 and a right locking gear 9. Gear 9, a lower left rack 10 and a lower right rack 11 are provided on the top of the lower locking frame 3, an upper left rack 12 and an upper right rack 13 are provided on the bottom of the upper locking frame 2, the left locking gear 8 is respectively meshed with the lower left rack 10 and the upper left rack 12, the right locking gear 9 is respectively meshed with the lower right rack 11 and the upper right rack 13, a driving wheel 14 is provided on the fixed seat 1, the driving wheel 14 is connected to the right locking gear 9 through a belt 15, and a locking handle 16 is installed on the driving wheel 14.

[0022] The fixing seat 1 is provided with slide grooves for limiting the upper locking frame 2 and the lower locking frame 3, and the upper locking frame 2 and the lower locking frame 3 can slide horizontally in their corresponding slide grooves. The lower left card plate 6 and the lower middle card plate 7 are provided with through holes for connecting the upper locking frame 2, so as to realize the left and right movement of the upper locking frame 2.

[0023] When the locking handle 16 is rotated counterclockwise, the driving wheel 14 is driven to rotate counterclockwise, and the driving wheel 14 drives the right locking gear 9 to rotate through the belt 15. The right locking gear 9 makes the upper locking frame 2 move to the left, and the lower locking frame 3 moves to the right at the same time, so that the upper right clamping plate 4 and the lower middle clamping plate 7 are close to each other to clamp the lower arc plate of one parallel groove wire clamp 26, and the upper middle clamping plate 5 and the lower left clamping plate 6 are close to each other to clamp the lower arc plate of another parallel groove wire clamp 26, so as to achieve the clamping and locking position.

[0024] The locking handle 16 is provided with a positioning hole 17. After the locking handle 16 is in place, the positioning hole 17 on the locking handle 16 is fixed to the base 1 by a bolt to achieve accurate locking positioning.

[0025] The lower left rack 10 and the lower right rack 11 are symmetrically arranged with the lower middle clamping plate 7 as the center, and the upper left rack 12 and the upper right rack 13 are symmetrically arranged with the upper middle clamping plate 5 as the center.

[0026] Reference Figure 3The transmission mechanism includes a gear box 25 and a servo motor 21, and the gear box 25 and the servo motor 21 are fixedly mounted on the fixed seat 1. A concave gear 18 is mounted in the middle of the gear box 25, and a left convex gear 19 and a right convex gear 20 are respectively meshed and connected on both sides of the concave gear 18, a left sleeve 23 is mounted on the left convex gear 19, and a right sleeve 24 is mounted on the right convex gear 20. The servo motor 21 is connected to the concave gear 18, and the left convex gear 19 and the right convex gear 20 are respectively meshed and connected on both sides of the concave gear 18 through the corresponding central gear 22, so that the left convex gear 19 and the right convex gear 20 have the same direction of rotation.

[0027] After the external power of the servo motor 21 is transmitted to the concave gear 18, the concave gear 18 transmits the power to the outermost left convex gear 19 and the right convex gear 20 through the central gears 22 on both sides. The left convex gear 19 is installed with a left sleeve 23, and the right convex gear 20 is installed with a right sleeve 24. The rotation of the left sleeve 23 and the right sleeve 24 can rotate and lock the two screws at the bottom of the parallel groove clamp 26.
