Description

Technical Field

[0001] This utility model relates to the field of power inspection and maintenance technology, and in particular to a portable power line spacer installation tool. Background Technology

[0002] Based on past experience in ultra-high voltage (UHV) engineering construction, it has been found that when installing six-split conductor spacers, traditional tools tighten the clamps by rotating screws, causing wear at the clamps due to friction between the tool and the spacer contact surface. Spacer installation is also a high-altitude operation, leading to rapid physical exertion for on-site workers. Furthermore, in winter, low temperatures cause the spacer rubber pads to harden during use, requiring greater force to tighten the clamps. Additionally, at some tower locations with significant elevation differences, the angle between the conductor and the ground is large, making it difficult to apply force while maintaining the spacer's perpendicularity to the conductor. All these factors contribute to reduced efficiency in installing multi-split spacers. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] Please refer to Figures 1 to 6 This utility model provides a portable power line spacer installation tool, including an installation groove 01 and a pressing mechanism 02 disposed within the installation groove 01. The bottom of the installation groove 01 is open, and a handle 03 is provided at the bottom of the installation groove 01. A support platform 04, parallel to the bottom of the installation groove 01, is provided at the lower end of the handle 03. The pressing mechanism 02 can move up and down in the longitudinal direction facing the support platform 04, thereby clamping or releasing the spacer through the interaction between the pressing mechanism 02 and the support platform 04. Utilizing the interaction between the pressing mechanism 02 and the support platform 04, the spacer is clamped by pressing. During the spacer installation process, the wear rate of the spacer clamping claws is zero, and the installation efficiency is far higher than that of traditional spacer installation tools. During operation, it effectively solves the problem of construction efficiency for on-site workers working at heights, reduces safety risks, and the galvanized layer on the surface of the spacer effectively protects the line, ensuring zero-defect deployment in the project. It has high promotional value.

[0025] In one embodiment, the pressing mechanism 02 includes a left end fixed seat 21, a right end fixed seat 22, a lead screw 23, and a pressing assembly 24. The left end fixed seat 21 and the right end fixed seat 22 are disposed opposite each other in the mounting groove 01. The left end fixed seat 21 and the right end fixed seat 22 can be fixed in the mounting groove 01 by screws for easy disassembly and installation. One end of the lead screw 23 is rotatably connected to the left end fixed seat 21, and the other end of the lead screw 23 passes through the right end fixed seat 22 and is rotatably connected to the right end fixed seat 22. The two ends of the top of the pressing assembly 24 are respectively threaded to the lead screw 23. When the lead screw 23 rotates circumferentially, it can drive the two ends of the pressing assembly 24 to bend synchronously towards the middle of the pressing assembly 24, so that the pressing assembly 24 forms a "V" shape. Alternatively, when the lead screw 23 rotates circumferentially, it can drive the two ends of the pressing assembly 24 to move synchronously towards the left end fixed seat 21 and the right end fixed seat 22, so that the pressing assembly 24 forms a "I" shape. When the pressing component 24 forms a "V" shape, it will cooperate with the support platform 04 to clamp the spacer bar; when the pressing component 24 forms a "I" shape, it will retract as a whole.

[0026] Specifically, the pressing assembly 24 includes a left connector 241, a right connector 242, a left tie rod 243, a right tie rod 244, and a pressing component 245. The left connector 241 and the right connector 242 are threadedly connected to the lead screw 23 in a symmetrical installation manner. The threaded connection between the left connector 241 and the lead screw 23 is opposite to that between the right connector 242 and the lead screw 23. Due to the function of the mounting groove 01, the left tie rod 243 and the right tie rod 244 can form a radial limit on the left connector 241 and the right connector 242 with the mounting groove 01 as a guide, thereby allowing the left connector 241 and the right connector 242 to move axially along the lead screw 23. The upper end of the left pull rod 243 is rotatably connected to the left connector 241, and the upper end of the right pull rod 244 is rotatably connected to the right connector 242. The two sides of the lower pressure member 245 are rotatably connected to the left pull rod 243 and the right pull rod 244, respectively. When the lead screw 23 rotates circumferentially, it can drive the left connector 241 and the right connector 242 to move synchronously along the lead screw 23. When the left connector 241 and the right connector 242 move synchronously towards the middle of the lead screw 23, they will synchronously drive the left pull rod 243 and the right pull rod 244 to exert downward pressure on the lower pressure member 245, causing the lower pressure member 245 to move downwards in the direction facing the support platform 04, thus shortening the distance between the lower pressure member 245 and the support platform 04. The pressing member 245 cooperates with the support platform 04 to achieve the gripping of the spacer bar. When the left end connector 241 and the right end connector 242 move synchronously to the left end fixed seat 21 and the right end fixed seat 22 respectively, the left end connector 241 and the right end connector 242 will synchronously drive the left pull rod 243 and the right pull rod 244 to form an upward pulling force on the pressing member 245, causing the pressing member 245 to move upward in the direction facing the support platform 04, so that the distance between the pressing member 245 and the support platform 04 increases, thereby releasing the spacer bar.

[0027] The top of the pressing member 245 is provided with a boss 246, and the two ends of the boss 246 are respectively rotatably connected to the left pull rod 243 and the right pull rod 244.

[0028] To enable the pressing member 245 to make better contact with the spacer bar, a top head 247 is provided at the bottom of the pressing member 245.

[0029] In one embodiment, a connector 05 is provided at the end of the lead screw 23 located on the right end of the fixed base 22. The connector 05 can be externally connected to a drive unit 08, thereby using the drive unit 08 to drive the entire lead screw 23 to rotate. The drive unit 08 can be a power tool, such as a manual drill. This manual drill needs to be modified by removing the drill bit and installing a shaft that is compatible with the connector 05.

[0030] In one embodiment, a pad 06 is provided on the support platform 04. The pad 06 can form good contact with the spacer bar while reducing wear on the spacer bar.

[0031] In one embodiment, an auxiliary gripping rod 07 is provided on the mounting slot 01. When the external drive unit 08 drives the lead screw 23 to rotate, one operator can use both hands to firmly grip the handle 03 and the auxiliary gripping rod 07 respectively, thereby maintaining the stability of the entire tool, while another operator can operate the drive unit 08.

[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
