Description

Technical Field

[0001] This utility model belongs to the technical field of power cable testing equipment, and in particular relates to a cable area measuring instrument. Background Technology

[0002] After power cables arrive at the construction site, their diameter needs to be measured, and the cross-sectional area is calculated based on the obtained diameter. Currently, cable diameter is measured manually using measuring tools, which has problems such as large errors, inconvenience in operation, and high labor intensity. Summary of the Invention

[0003] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a cable area measuring instrument with novel structure, high measurement accuracy, small error, easy operation, and low labor intensity.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A cable area measuring instrument includes: a support platform, a controller, and a photoelectric ranging device. The controller is electrically connected to the photoelectric ranging device. Its features include: a ranging reference surface and an arc-shaped groove on the support platform, with the ranging reference surface and the bottom of the arc-shaped groove on the same horizontal plane; a lifting mechanism on the support platform, with a pressure plate connected to its output end; a pressure sensor on the bottom surface of the pressure plate; the controller is electrically connected to the pressure sensor and the lifting mechanism, with the pressure sensor located above the arc-shaped groove; the photoelectric ranging device is mounted on the pressure plate, above the ranging reference surface; and cable clamps are located on the sides of the support platform, on both sides of the arc-shaped groove, for clamping cables. This measuring instrument has a novel structure, high measurement accuracy, small error, is easy to operate, and requires low labor intensity.

[0006] Furthermore, the cable clamp includes an L-shaped support base, a pressure block, and a pressure rod. The pressure block is vertically slidably connected to the L-shaped support base, and the pressure rod is screwed onto the L-shaped support base. The pressure rod is used to press down on the pressure block. When clamping the cable, first place the cable on the L-shaped support base, then slide the pressure block down, and then rotate the pressure rod so that the lower end of the pressure rod presses down on the pressure block, preventing the pressure block from moving upwards. This allows the pressure block, in conjunction with the L-shaped support base, to stably clamp the cable and prevent it from swinging freely.

[0007] Furthermore, the support platform is slidably connected to an L-shaped support base. A fixed base is provided on the side of the support platform, and a push rod is screwed onto the fixed base. One end of the push rod is rotatably connected to the L-shaped support base. Rotating the push rod can drive the L-shaped support base to slide horizontally, ensuring sufficient contact between the L-shaped support base and the cable, thus adapting to cables of different diameters and exhibiting strong adaptability.

[0008] Furthermore, the clamping block includes a horizontal part and an inclined part. The horizontal part is connected to the inclined part and is vertically slidably connected to the L-shaped support base. The inclined part cooperates with the L-shaped support base to clamp the cable. The contact area is large, the cable is not easy to loosen freely, and the clamping is reliable.

[0009] Furthermore, the horizontal and inclined sections are integrally molded, allowing for rapid prototyping, structural stability, and reliable use.

[0010] Furthermore, the pressure plate is provided with mounting through holes corresponding to the photoelectric ranging device. The photoelectric ranging device is fixed to the pressure plate with screws, which is reliable, easy to install, and simple and convenient.

[0011] Furthermore, the lifting mechanism uses a stroke cylinder, which has advantages such as a large stroke, convenient installation, and reliable and stable use.

[0012] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0013] When clamping the cable, first place the cable on the L-shaped support base, then slide the pressure block down so that the inclined part of the pressure block presses down on the cable. Next, rotate the pressure rod so that the lower end of the pressure rod presses down on the horizontal part of the pressure block, preventing the pressure block from moving upward. This allows the pressure block and the L-shaped support base to stably clamp the cable, providing two-point clamping to keep the cable straight within the arc groove and prevent the cable from twisting or bending, which would affect the measurement results. During measurement, the stroke cylinder is activated, causing the pressure plate to descend. When the pressure sensor touches the cable, the pressure sensor sends a signal to the controller. The controller then stops the stroke cylinder and activates the photoelectric distance measuring device. The distance measured by the photoelectric distance measuring device is the cross-sectional diameter of the cable. The photoelectric distance measuring device sends the data to the host computer, which calculates the cross-sectional area. Attached Figure Description

Detailed Implementation

[0021] like Figures 1 to 5 As shown, this utility model cable area measuring instrument includes: a support platform 1, a controller, and a photoelectric ranging device 2. The controller is electrically connected to the photoelectric ranging device 2. The photoelectric ranging device 2 can be a laser sensor or a laser rangefinder, which is existing technology and will not be described in detail here. The support platform 1 is provided with a ranging reference surface 3 and an arc groove 4. The ranging reference surface 3 and the bottom of the arc groove 4 are located on the same horizontal plane. The side of the support platform 1 is provided with a fixing plate 5. The fixing plate 5 is provided with a support frame 6 and a fixing base 7. The support frame 6 is provided with a lifting mechanism. The lifting mechanism adopts a stroke cylinder 8, which has the advantages of large stroke, convenient installation, and reliable and stable use. The output end of the stroke cylinder 8 is connected to a pressure plate 9. A pressure sensor 10 is provided on the bottom surface of the pressure plate 9. The controller is electrically connected to the pressure sensor 10 and the stroke cylinder 8. The pressure sensor 10 is located above the arc groove 4.

[0022] The pressure plate 9 is provided with mounting through holes 11 corresponding to the photoelectric ranging device 2. The photoelectric ranging device 2 is fixed to the pressure plate 9 by screws. The fixing is reliable, easy to install, and simple and convenient. The photoelectric ranging device 2 is located above the ranging reference surface 3.

[0023] A wire clamp 12 is provided on the side of the support platform 1. The wire clamp 12 is located on both sides of the arc groove 4. The wire clamp 12 includes an L-shaped support base 13, a pressure block 14 and a pressure rod 15. The upper surface of the horizontal section of the L-shaped support base 13 is on the same horizontal plane as the bottom of the arc groove 4. The pressure block 14 includes a horizontal part 16 and an inclined part 17. The horizontal part 16 and the inclined part 17 are integrally formed, which can be quickly formed, has a stable structure and is reliable in use. The horizontal part 16 is vertically slidably connected to the L-shaped support base 13. The pressure rod 15 is screwed to the L-shaped support base 13. The L-shaped support base 13 is slidably connected to the side of the support platform 1. A push rod 18 is screwed onto the fixed base 7. One end of the push rod 18 is rotatably connected to the L-shaped support base 13.

[0024] Rotating the push rod 18 can drive the L-shaped support 13 to slide horizontally, ensuring that the L-shaped support 13 makes full contact with the cable, so as to adapt to cables of different diameters and has strong adaptability.

[0025] When clamping cable 19, first place cable 19 on L-shaped support base 13, then slide down pressure block 14 so that the inclined part 17 of pressure block 14 presses down on cable 19. Next, rotate pressure rod 15 so that the lower end of pressure rod 15 presses down on the horizontal part 16 of pressure block 14, preventing pressure block 14 from moving upward. Pressure block 14, together with L-shaped support base 13, stably clamps cable 19, clamping cable 19 at two points, keeping cable 19 straight in arc groove 4, preventing cable 19 from twisting or bending and affecting measurement results. During measurement, start stroke cylinder 8 to drive pressure plate 9 down. When pressure sensor 10 touches cable 19, pressure sensor 10 sends a signal to controller. Controller controls stroke cylinder 8 to stop working and controls photoelectric distance measuring device 2 to start. At this time, the distance measured by photoelectric distance measuring device 2 is the cross-sectional diameter of cable 19. Photoelectric distance measuring device 2 sends data to host computer, which calculates the cross-sectional area.
