Description

Technical Field

[0001] This utility model belongs to the field of power construction technology, and specifically relates to an auxiliary measuring tool for power construction. Background Technology

[0002] During the installation of power systems, utility poles serve as supporting structures, and crossarms are typically fixed to their tops. The main function of the crossarm is to install insulators and fittings, support conductors and lightning rods, and maintain a safe distance. To ensure safe cable distances, the crossarm installation must meet design requirements regarding the distance between the crossarm and the top of the pole. Specifically, for 10kV and low-voltage lines, the horizontal distance between the center plane of the crossarm and the top of the pole is 15cm; for 10kV lines, the horizontal distance between the center plane of the lower crossarm and the center plane of the upper crossarm is 60cm; for low-voltage lines, the horizontal distance between the center plane of the lower crossarm and the center plane of the upper crossarm is 30cm; the center line of the upper clamp on a single-top support is 15cm from the top of the pole; and for a double-top support, the center line of the upper clamp is 35cm from the top of the pole. Currently, these distances are typically measured by workers using a measuring tape. However, due to the high-altitude work, workers often lack stability, and the top of the utility pole is generally rough, making it difficult for workers to hook the measuring tape onto the correct position in one attempt. This often requires multiple attempts, which is inconvenient. Even when the hook is in place, the reading can easily slip, seriously affecting work efficiency. In addition, some construction workers may look up or down to read the measurement in order to avoid multiple operations, which makes the measurement inaccurate. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary measuring tool for power construction.

[0004] This utility model is achieved through the following measures: an auxiliary measuring tool for power construction, characterized in that it includes a circular ring plate with an inner diameter larger than the outer diameter of the utility pole, an annular groove is provided on the outer wall of the circular ring plate, a horizontal plate is provided above the circular ring plate and spans the circular ring plate, both ends of the horizontal plate extend out of the circular ring plate and are provided with rollers, the two rollers are provided in the annular groove and can move along the annular groove, a stud is fixedly provided on the upper end face of the horizontal plate and outside the rollers, and the hook of the measuring tape is provided on the stud and fixed by a nut;

[0005] The lower inner wall of the circular ring plate has at least three ear plates evenly distributed circumferentially. The inner end of each ear plate is provided with a downward-facing upright plate. Each upright plate is provided with a screw connected by threads, and the inner end of the screw can press against the outer wall of the utility pole. Generally, three ear plates are provided.

[0006] Furthermore, the ruler hook is generally provided with a through hole or U-shaped groove that mates with the stud.

[0007] Furthermore, the horizontal plate has downward-facing vertical plates at both ends, and the steel tape of the measuring tape can fit against the outer wall of the vertical plates;

[0008] Limiting plates are provided on the vertical plate and on both sides of the steel ruler strip.

[0009] Furthermore, the upper end face of the circular ring plate is concentrically provided with an annular groove, and bullseye bearings are symmetrically arranged on the horizontal plate, with the bottom wall of the bullseye bearings being tangent to the bottom wall of the annular groove.

[0010] Furthermore, the roller is rotatably mounted on the U-shaped frame, a screw is fixedly mounted on the upper end face of the U-shaped frame, the horizontal plate is provided with mounting holes that cooperate with the screw, and the horizontal plate is sleeved on the screw and fixed by a nut.

[0011] One stud is provided.

[0012] The length of the vertical plate and the limiting plate is less than 15cm, generally 5cm-10cm, so as not to affect normal measurement.

[0013] The combination of the bullseye bearing and the roller allows the horizontal plate to be moved easily by a measuring tape.

[0014] How to use:

[0015] The roller is pre-placed in the annular groove of the circular ring plate and fixed in place by a horizontal plate, ensuring that the bullseye bearing is positioned within the annular groove. The lower end face of the horizontal plate should contact the upper end face of the circular ring plate. Finally, the hook of the measuring tape is fixed to the stud with a nut.

[0016] In use, place the horizontal plate on top of the utility pole, ensuring it is flush against the top. Then, rotate the screws to secure the tool to the pole. When rotating the screws, ensure all screws extend to the same length and that the circular ring plate is concentric with the pole to minimize measurement errors.

[0017] When measurements are needed, simply pull the outer casing of the measuring tape to the designated position and take the reading; there's no need to worry about the hook falling off. When adjusting the position, workers can pull the measuring tape, which in turn moves the rollers to rotate the horizontal plate along the annular groove, allowing for easy changes to the measurement position.

[0018] When the top of the utility pole is not used as a reference, the distance can be obtained by subtracting two readings.

[0019] The beneficial effects of the technical solution provided by this utility model embodiment are: to assist manual measurement of the distance between the crossarm to be installed on the utility pole and the top of the utility pole, the distance between the two crossarms, and the relative positions of other installation components.

Of course, the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0028] See Figures 1-5 An auxiliary measuring tool for power construction is characterized by comprising a circular ring plate 1 with an inner diameter larger than the outer diameter of a utility pole, an annular groove 101 on the outer wall of the circular ring plate 1, a horizontal plate 2 spanning the circular ring plate 1 above the circular ring plate 1, both ends of the horizontal plate 2 extending out of the circular ring plate 1 and each end of the extending end is provided with a roller 3, the two rollers 3 are disposed in the annular groove 101 and can move along the annular groove 101, a stud 4 is fixedly disposed on the upper end surface of the horizontal plate 2 and located outside the roller 3, and the hook 502 of the measuring tape 5 is disposed on the stud 4 and fixed by a nut;

[0029] The lower inner wall of the circular ring plate 1 has at least three ear plates 6 evenly distributed circumferentially. The inner end of each ear plate 6 is provided with a downward-facing upright plate 601. Each upright plate 601 is provided with a screw 7 by threaded connection. The inner end of the screw 7 can abut against the outer wall of the utility pole. There are generally three ear plates 6.

[0030] The ruler hook 502 is generally provided with a through hole or U-shaped groove that mates with the stud 4.

[0031] The horizontal plate 2 has downward-facing vertical plates 8 at both ends, and the steel tape 501 of the measuring tape 5 can fit against the outer wall of the vertical plate 8.

[0032] Limiting plates 801 are provided on the vertical plate 8 and on both sides of the steel ruler belt 501.

[0033] The upper end face of the circular ring plate is concentrically provided with an annular groove 102, and bullseye bearings 9 are symmetrically arranged on the horizontal plate 2. The bottom wall of the bullseye bearings 9 is tangent to the bottom wall of the annular groove 102.

[0034] The roller 3 is rotatably mounted on the U-shaped frame 301. The upper end face of the U-shaped frame 301 is fixedly mounted with a screw 302. The horizontal plate 2 is provided with a mounting hole that mates with the screw 302. The horizontal plate 2 is sleeved on the screw 302 and fixed with a nut.

[0035] There is one stud 4.

[0036] The lengths of the vertical plate 8 and the limiting plate 801 are less than 15cm, generally 5cm-10cm, so as not to affect normal measurement.

[0037] How to use:

[0038] The roller 3 is placed in the annular groove 101 of the circular ring plate 1 beforehand, and is connected and fixed by the horizontal plate 2, while ensuring that the bullseye bearing 9 is placed in the annular groove 102.
