Description

Technical Field

[0001] The invention belongs to the technical field of measuring equipment, and in particular relates to a measuring mechanism used for power supply construction. Background Art

[0002] During the construction of power supply lines, the overhead cables between the two towers will inevitably sag due to gravity and produce a certain curvature. Excessive sag will not only cause potential accidents in crowded areas or cross-over work points, but also limit the transmission capacity of the line. The inclination angle of the transmission line is an important reference indicator for calculating the sag of the transmission line. Therefore, it is necessary to measure the inclination angle of the line to ensure the stable installation of the power supply line.

[0003] A cable inclination angle measuring device with publication number CN116067345A in the prior art is provided, which comprises two vertically mounted first measuring frames and second measuring frames, wherein the first measuring frames and the second measuring frames are both slidably mounted with sliding clamping parts, and the two sliding clamping parts clamp the section of the cable or pipeline to be detected. During use, the position of the vertically mounted sliding clamping parts is adjusted to achieve reverse support and height adjustment of one end of the first measuring frame. The horizontal setting of the first measuring frame can be easily calibrated in conjunction with two leveling bubbles. The sliding setting can detect cables or pipelines with different inclination angles. By vertically sliding the top end of the second measuring frame on the first measuring frame, the length of the detection cable or pipeline section can be controlled by adjusting the clamping distance from the vertical intersection of the first measuring frame and the second measuring frame to the horizontally mounted sliding clamping parts.

[0004] Although it is possible to detect cables or pipes with different inclination angles, there are still some defects in actual use. Since the display screen position of the measuring instrument is fixed, when it is blocked by obstacles during use or the cable installation direction needs to be turned over for measurement, the display screen cannot be adjusted accordingly, which makes it inconvenient for measurement personnel to observe the measured values, greatly reducing the convenience of the device and failing to meet daily use needs.

DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-Figure 8 A measuring mechanism for power supply construction shown in the figure comprises a horizontal frame 1 and a display 3, and a vertical frame 2 fixedly connected to the bottom of the horizontal frame 1, and the horizontal frame 1 is L-shaped after being connected to the vertical frame 2, and an adjustment groove 4 is provided through the horizontal frame 1 and the vertical frame 2, and a sliding block 5 is slidably connected to the inner side of the adjustment groove 4, and a clamping mechanism 8 for clamping a cable is provided on the side wall of the sliding block 5, and a moving mechanism 25 for adjusting the position of the clamping mechanism 8 and the sliding block 5 is provided on the inner side of the adjustment groove 4, and the clamping mechanism 8 and the moving mechanism 25 are both mature technologies in the prior art, and no more description is given here, and an inwardly recessed rectangular groove 6 is provided on the front side of the horizontal frame 1 and located above the vertical frame 2 and is connected to the adjustment groove 4, and a rectangular block 7 is fixedly connected to the inner side of the rectangular groove 6, and an adjustment mechanism for adjusting the angle of the display 3 is provided on the front side of the rectangular block 7;

[0027] The adjustment mechanism includes a gear ring 9 and a gear plate 10. An L-shaped groove 11 is provided on the front side of the rectangular block 7. An upper laser rangefinder 12 and a lower laser rangefinder 13 are fixedly connected to the inner side of the L-shaped groove 11. The measuring method of the measuring device mainly clamps the cable through the clamping mechanism 8, and then measures the distance between the two clamping positions through the upper laser rangefinder 12, the lower laser rangefinder 13 and the reflector 14. Finally, the inclination angle of the cable is calculated by the processor. The calculation method is a mature technology in the prior art and will not be described in detail here. , and the front side of the sliding block 5 is fixedly connected with a reflector 14 for receiving laser signals, the front side of the rectangular block 7 is fixedly connected with a fixing plate 15, the gear ring 9 is rotatably connected to the front side of the fixing plate 15, the rectangular block 7 and the fixing plate 15 are provided with an inward-recessed card slot 16, the tooth plate 10 is slidably connected to the inner side of the card slot 16 and meshes with the gear ring 9, the front side of the gear ring 9 is fixedly connected with a fixing cylinder 17, the display 3 is fixedly connected to the front side of the fixing cylinder 17, and an upper spring 18 is fixedly connected between the inner side of the card slot 16 and the tooth plate 10;

[0028] When the measuring device needs to be reversed and the angle of the display 3 needs to be adjusted, the limiting cylinder 20 is first pressed to drive the toothed plate 10 to slide backward, thereby driving the toothed plate 10 to slide out of the meshing position with the toothed ring 9, and at the same time compressing the upper spring 18 and the lower spring 24, thereby releasing the rotation restriction of the toothed ring 9, and when the limiting cylinder 20 is pressed, it will slide out of the fit with the fixing cylinder 17, and then after the display 3 is rotated to reach the specified position, the limiting cylinder 20 can be released, and then the limiting cylinder 20 is pushed to reset by the elastic force of the upper spring 18 and the lower spring 24, thereby driving the toothed plate 10 to move to the meshing position with the toothed ring 9, thereby fixing the position of the display 3. At the same time, due to the limiting cylinder 20 The position limit tube 20 and the fixed tube 17 are both rectangular in shape, so that the display 3 can be adjusted to four directions (the rectangular structure can be completely aligned as long as one of them faces it, so the alignment process is not complicated). If the rotation angle of the display 3 is not adjusted to a horizontal state, the limit tube 20 cannot be inserted during resetting, and the gear ring 9 has not moved to a position meshing with the gear plate 10, thereby ensuring that the display 3 is adjusted to a horizontal state, and the gear ring 9 has also moved to a position meshing with the gear plate 10, and at the same time, the rotation position of the fixed tube 17 can be further restricted. Finally, after use, the display 3 can be reset by reverse operation, which can ensure that the subsequent limit tube 20 can normally block the lens.

[0029] In order to prevent the rotation of the display 3 from affecting the electrical connection between it and the upper laser rangefinder 12 and the lower laser rangefinder 13, a through hole 19 is opened on the front side of the fixed plate 15 and at a position corresponding to the gear ring 9. During installation, the wires on the upper laser rangefinder 12 and the lower laser rangefinder 13 can be connected to the controller on the display 3 through the through hole 19 and the inner side of the gear ring 9, and the wires are spring cables, so that the spring cables can be rotated when the display 3 rotates to avoid hindering the angle adjustment of the display 3. A stop block 30 is fixedly connected to the inner side of the gear ring 9, and a positioning block 31 for limiting the rotation of the gear ring 9 is fixedly connected to the front side of the fixed plate 15 and located next to the stop block 30. Through the arrangement of the stop block 30 and the positioning block 31, the number of rotations of the gear ring 9 can be limited to avoid excessive rotations causing wire entanglement, which affects the connection between the display 3 and the upper laser rangefinder 12 and the lower laser rangefinder 13.

[0030] In order to shield the lenses of the upper laser rangefinder 12 and the lower laser rangefinder 13 when the measuring equipment is not in use, the inner side of the rectangular groove 6 is slidably connected to the limiting cylinder 20, and the front side of the limiting cylinder 20 extends a part of the inner side of the rectangular groove 6 and fits with the outer side of the fixed cylinder 17, the tooth plate 10 is fixedly connected to the inner side of the limiting cylinder 20, and the outer wall of the limiting cylinder 20 and the positions corresponding to the upper laser rangefinder 12 and the lower laser rangefinder 13 are provided with ranging holes 21, and a plurality of lower springs 24 are fixedly connected between the inner side of the rectangular groove 6 and the side wall of the limiting cylinder 20;

[0031] Both sides of the inner wall of the limiting cylinder 20 are provided with inwardly sunken fixing grooves 26, the inner sides of the fixing grooves 26 are provided with upper L-shaped rods 27, and the side walls are all arranged through the outer wall of the limiting cylinder 20, a fixing spring 28 is fixedly connected between the inner side of the fixing grooves 26 and the top of the side wall of the upper L-shaped rod 27, and a lower L-shaped rod 29 is fixedly connected to the outer wall of the fixing cylinder 17 and located beside the upper L-shaped rod 27, and the vertical end of the upper L-shaped rod 27 is butted against the vertical end of the lower L-shaped rod 29;

[0032] After the measuring device is used, the two upper L-shaped rods 27 can be pressed toward the middle to slide in the fixing groove 26, so that the upper L-shaped rod 27 slides out of the mortgage position with the lower L-shaped rod 29, and the fixing spring 28 is compressed at the same time, and then the upper L-shaped rod 27 is pulled to drive the limit cylinder 20 to slide outward, and at the same time the lower spring 24 and the upper spring 18 are stretched, and the tooth plate 10 is driven to slide on the outside of the tooth ring 9 to maintain the limiting effect on the display 3, so that the distance measuring hole 21 is moved out of the upper laser rangefinder 12 and the lower laser rangefinder 1 3 lens, and then after the upper L-shaped rod 27 passes through the lower L-shaped rod 29, the upper L-shaped rod 27 can be loosened, and then the upper L-shaped rod 27 is pushed to move to the front side of the lower L-shaped rod 29 by the elastic force of the fixing spring 28, so that the position of the limit cylinder 20 is fixed by the lower L-shaped rod 29, and then the lens of the upper laser rangefinder 12 and the lower laser rangefinder 13 is shielded by the inner side of the limit cylinder 20 to prevent dust and other impurities from adhering to the lens when not in use, affecting the accuracy of subsequent measurements, and the reverse operation can be performed when it is opened again.

[0033] In order to automatically wipe the lens after use, an inward groove 22 is provided on the inner side of the limit cylinder 20 and located at the ranging hole 21, and a sponge block 23 for wiping the lenses of the upper laser rangefinder 12 and the lower laser rangefinder 13 is fixedly connected to the inner side of the groove 22. By using the sponge block 23 arranged in the groove 22, when the limit cylinder 20 is pulled outward to block the upper laser rangefinder 12 and the lower laser rangefinder 13, the sponge block 23 can be driven to move to the side of the lens. Then, when used next time, the sponge block 23 can be driven to move on the lens by pushing the limit cylinder 20, so that dust or impurities adhered to the lens during the measurement process can be wiped off.

[0034] In order to ensure the horizontality during the measurement process, a level bubble 32 is fixedly connected to the top of the display 3. Through the setting of the level bubble 32, the levelness of the measuring device can be adjusted by observing the position of the bubble on the level bubble 32 when the measuring device clamps the cable, thereby ensuring the accuracy of the measurement. Moreover, since it is set on the display 3, it can be always copied together with the display 3 during adjustment, which is convenient for observing the levelness of the measuring device when the measuring device is used in reverse.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
