Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0026] This utility model discloses a high-efficiency cable length measuring device, comprising a base 1, an unwinding assembly, a gantry frame 18, rollers 19, a lifting assembly, a contact wheel 22, a measuring wheel 24, and a meter counter 25; the specific structure is as follows: Figures 1-3 As shown, a winding assembly is provided on the left side of the upper surface of the horizontally arranged base 1, and the winding reel 4 is horizontally and longitudinally mounted on the winding assembly; a portal frame 18 with an opening slot is also provided on the right side of the upper surface of the base 1, and the opening end of the portal frame 18 is fixedly connected to the corresponding position of the upper surface of the base 1; a roller 19 is also provided horizontally and longitudinally within the portal frame 18 relative to the position of the winding reel 4, the upper end face of the roller 19 is located in the same horizontal plane as the center of the winding reel 4, and it is arranged horizontally and longitudinally in the same straight line as the center of the winding reel 4; the roller 19 is matched with the cable to be tested, and its two ends are respectively rotatably connected to the corresponding positions of the inner side of the portal frame 18 around its own axis.

[0027] like Figures 1-3 As shown, an abutment wheel 22 matching the roller 19 is provided inside the gantry frame 18 directly above the roller 19, and a second rotating shaft 23 is provided coaxially at both ends of the abutment wheel 22; the abutment wheel 22 is rotatably connected to the lifting end of the lifting assembly through the second rotating shaft 23, and moves vertically up and down in the area above the roller 19 within the gantry frame 18 by the drive of the lifting assembly; the front end of the second rotating shaft 23 extends vertically out of the lifting end of the lifting assembly, and is coaxially sleeved and fixed with the measuring wheel 24, and a meter counter 25 is also provided at the lifting end of the lifting assembly, so that the length of the cable is measured by the cooperation of the meter counter 25 and the measuring wheel 24.

[0028] The lifting assembly includes a cylinder 21 and a lifting frame 20; such as Figures 1-3 As shown, a gate-shaped lifting frame 20 is provided inside the gantry frame 18, directly above the roller 19. The opening slot of the lifting frame 20 is horizontally arranged, and its opening end faces downward. The abutment wheel 22 is arranged on the same plane as the roller 19, and its two ends are respectively connected to the lifting frame 20 around its own axis through the second rotating shaft 23, ensuring that the lifting frame 20 does not interfere with the rotation of the abutment wheel 22. The lower end face of the abutment wheel 22 extends out of the lower surface of the lifting frame 20, and a cylinder 21 is vertically provided on the upper surface of the gantry frame 18 relative to the center position of the lifting frame 20. The telescopic end of the cylinder 21 extends vertically downward into the interior of the gantry frame 18 and is screwed to the upper surface of the lifting frame 20, thereby driving the lifting frame 20 to move vertically up and down in the area above the roller 19 inside the gantry frame 18 to adjust the distance between the abutment wheel 22 and the roller 19, so as to ensure that the abutment wheel 22 and the roller 19 are in tight contact with the upper and lower surfaces of the cable to be tested.

[0029] like Figures 1-3 As shown, the measuring wheel 24 matches the detection wheel of the meter counter 25, and the lifting frame 20 does not interfere with the synchronous rotation of the measuring wheel 24 and the clamping wheel. A fixing plate 26 is horizontally and longitudinally fixed on the front surface of the lifting frame 20 relative to the right side of the measuring wheel 24, and the mounting end of the meter counter 25 is fixedly connected to the lower surface of the fixing plate 26 near the front via a fixing rod. The gantry frame 18 does not interfere with the vertical up-and-down movement of the meter counter 25 with the lifting frame 20, and the detection wheel of the meter counter 25 is positioned towards the rear and is horizontally and coplanar with the measuring wheel 24. Thus, the length of the cable to be measured is measured through the abutting contact between the detection wheel of the meter counter 25 and the measuring wheel 24. The meter counter 25 of this utility model is a conventional product, so its structure will not be described in detail here.

[0030] The unwinding assembly of this utility model includes a vertical plate I2, a pad 27, a vertical plate II3, a second electric push rod 28, a connecting plate 5, and a first rotating shaft 6; as shown Figures 1-3As shown, on the upper surface of the base 1, on the left side, there are vertical plates II3 and I2 arranged horizontally and vertically at intervals. The vertical plate II3 is L-shaped and is located on the front side, with its vertical side pointing vertically upward and its horizontal side pointing to the rear. It is horizontally and longitudinally slidably connected to the base 1. On the upper surface of the base 1, relative to the front side of the vertical plate II3, there is a horizontally and longitudinally arranged second electric push rod 28. The tail of the second electric push rod 28 is fixedly connected to the base 1 through a rib plate, and its pushing end is screwed to the bottom end of the outer surface of the vertical side of the vertical plate II3 in the rear direction. This pushes the vertical plate II3 to perform horizontal and longitudinal reciprocating motion in the area in front of the vertical plate I2 to adjust the distance between the vertical plate I2 and the vertical plate II3.

[0031] like Figures 1-3 As shown, vertical plate I2 is a rectangle that matches the vertical edge of vertical plate II3. A horizontal pad 27 is horizontally positioned on the upper surface of base 1 relative to vertical plate I2. The lower surface of vertical plate I2 is fixedly positioned at the rear edge of the upper surface of the pad 27, ensuring that the lower surface of vertical plate I2 and the upper surface of the horizontal edge of vertical plate II3 are on the same horizontal plane. A vertically and horizontally aligned connecting plate 5 is symmetrically positioned between vertical plate I2 and vertical plate II3, with both connecting plates 5 spaced apart directly above base 1. At each connecting plate... The outer side of plate 5 is also horizontally and longitudinally coaxially fixed with a first rotating shaft 6. The rear end of the first rotating shaft 6 is connected to the front surface of the vertical plate I2 via a bearing and rotates around its own axis. The front end of the first rotating shaft 6 is connected to the inner surface of the vertical edge of the vertical plate II3 via a bearing and rotates around its own axis. The wire feeding wheel 4 of this utility model is horizontally and longitudinally arranged between the two connecting plates 5 and directly above the base 1. Its two end faces are respectively coaxially screwed to the corresponding connecting plates 5, so that the wire feeding wheel 4 rotates with the first rotating shaft 6 to perform the unwinding operation of the cable to be tested.

[0032] like Figures 1-3 As shown, the distance between the two connecting plates 5 matches the distance between the two end faces of the feeding wheel 4, and the diameter of each connecting plate 5 matches the diameter of the two end faces of the feeding wheel 4. Several rings of mounting holes 10 are vertically embedded on the outer side of each connecting plate 5, and each mounting hole 10 extends vertically out of the inner side of the corresponding connecting plate 5. Each ring of mounting holes 10 is coaxially opened on the corresponding connecting plate 5, and its opening position corresponds to the position of the end face fixing hole of the feeding wheel 4 with different diameters. Then, through the cooperation of the fixing hole and the corresponding mounting hole 10, the two end faces of the feeding wheel 4 are coaxially screwed and fixed to the corresponding connecting plate 5.

[0033] like Figures 1-3As shown, an annular groove 7 is coaxially and vertically embedded in the middle of the outer circumference of each connecting plate 5, and each groove 7 is not interfered with by the mounting hole 10, and does not extend beyond the inner or outer side of the corresponding connecting plate 5; a first slider 9 matching the groove 7 is provided on the upper surface of the pad 27 relative to the position of the corresponding connecting plate 5, and on the upper surface of the horizontal side of the vertical plate II 3 relative to the position of the corresponding connecting plate 5, and each first slider 9 is fixedly installed on the upper surface of the corresponding pad 27 or the upper surface of the horizontal side of the vertical plate II 3 by the corresponding fixing block 8, thereby ensuring the stability of the wire feeding wheel 4 rotating with the first rotating shaft 6 through the cooperation of the first slider 9 and the groove 7.

[0034] like Figures 1-3 As shown, on the lower surface of the horizontal edge of the vertical plate II3, there are also horizontally longitudinally arranged second sliders 30 symmetrically spaced on the left and right, and on the upper surface of the base 1, there are also horizontally longitudinally arranged slide rails 29 that match the second sliders 30. Thus, the stability of the horizontal longitudinal sliding of the vertical plate II3 is ensured by the cooperation between the slide rails 29 and the second sliders 30. On the upper surface of the base 1, there are also vertically arranged limit plates 31 at the rear end of each slide rail 29, and the horizontal longitudinal sliding of the vertical plate II3 is limited by the limit plates 31.

[0035] like Figures 1-3 As shown, a first bracket 11 is vertically mounted on the upper surface of the base 1, located to the left of the vertical plate I2 and relative to the position of the wire feeding wheel 4. A first electric push rod 12 is horizontally mounted on the upper end of the first bracket 11. The pushing end of the first electric push rod 12 is mounted on the same horizontal plane as the center line of the wire feeding wheel 4 and extends towards the wire feeding wheel 4. A pressure claw 13 is also provided between the first electric push rod 12 and the wire feeding wheel 4. The pressure claw 13 is a vertically mounted triangular structure, and its side away from the wire feeding wheel 4 is fixedly connected to the pushing end of the first electric push rod 12. The two sides of the pressure claw 13 near the wire feeding wheel 4 are both mounted on the same vertical plane. A pressure roller 14 with a length corresponding to the width of the wire feeding wheel 4 is also coaxially mounted on it. Each pressure roller 14 is horizontally mounted and fits against the cable to be tested on the wire feeding wheel 4 to ensure that the wire feeding wheel 4 feeds the wire in an orderly manner.

[0036] like Figures 1-3As shown, on the upper surface of the base 1, symmetrical second supports 15 are provided on both sides of the portal frame 18 and on the right side of the vertical plate I2, and the two second supports 15 are spaced apart from the portal frame 18; each second support 15 is an inverted U-shaped structure, and its opening slot is arranged horizontally, with its opening end facing downward and fixedly connected to the corresponding position on the upper surface of the base 1; the internal longitudinal span of each second support 15 is greater than the width of the roller 19 and less than the width of the feeding wheel 4; in each second support 15, upper clamping rollers 16 and lower clamping rollers 17 are also arranged horizontally and longitudinally at intervals, and the roller surface length of each upper clamping roller 16 and lower clamping roller 17 matches the width of the roller 19, and the upper end face of each lower clamping roller 17 is horizontally coplanar with the upper end face of the roller 19; the two ends of each lower clamping roller 17 are respectively connected to the upper end face of the roller 19. The inner side of the corresponding second bracket 15 is rotatably connected around its own axis, and a third rotating shaft is coaxially provided at both ends of each upper clamping roller 16. One end of each third rotating shaft is rotatably connected to the corresponding upper clamping roller 16 around its own axis, and the other end extends vertically out of the corresponding outer side of the corresponding second bracket 15. On the two outer sides of each second bracket 15, a waist-shaped hole matching the third rotating shaft is vertically embedded and opened relative to the position of the third rotating shaft. Each upper clamping roller 16 moves vertically up and down along the corresponding waist-shaped hole through the third rotating shaft to adjust the distance between the upper clamping roller 16 and the lower clamping roller 17. The third rotating shaft is then screwed and fixed to the outer side of the corresponding second bracket 15 by a nut. Thus, through the cooperation of the upper clamping roller 16 and the corresponding lower clamping roller 17, the cable to be tested passing between them is kept in a taut state.

[0037] The working principle of this utility model:

[0038] First, by cooperating with the second electric push rod 28 and the mounting hole 10, the wire feeding wheel 4 is installed between the two connecting plates 5. Then, one end of the cable to be tested on the wire feeding wheel 4 is passed to the right sequentially between the upper clamping roller 16 and the lower clamping roller 17 on the left side, between the abutment wheel 22 and the roller 19, and between the upper clamping roller 16 and the lower clamping roller 17 on the right side, and then wound onto the winding mechanism. At this time, the length of the cable to be tested located between the roller 19 and the winding mechanism is measured manually.

[0039] Then, adjust the distance between the upper clamping roller 16 and the lower clamping roller 17, and the distance between the abutting wheel 22 and the roller 19 according to the specifications of the cable to be tested, so as to ensure that the upper clamping roller 16 and the lower clamping roller 17 are in contact with the upper and lower surfaces of the cable to be tested respectively, and ensure that the abutting wheel 22 and the roller 19 cooperate to squeeze the cable to be tested.

[0040] Then the winding mechanism starts to wind up the cable under test. During the winding process, the cable under test will drive the abutment wheel 22 to rotate synchronously, and drive the measuring wheel 24 to rotate synchronously. The length of the cable under test can then be measured by counting with the meter counter 25.

[0041] The beneficial effects of this utility model are:

[0042] (1) This utility model uses the roller 19, the abutment roller 22, the second rotating shaft 23, the measuring roller 24, the meter counter 25, the upper clamping roller 16 and the lower clamping roller 17 in combination to facilitate the length measurement of the cable to be measured by the meter counter 25, and ensures that the cable to be measured is in a taut state during the process, thereby reducing the probability of errors in length measurement, saving time and effort, and improving measurement efficiency;

[0043] (2) By setting multiple mounting holes 10 and cooperating with the second electric push rod 28, this utility model can install and fix wire feeding wheels 4 of different specifications, thereby facilitating the length measurement of cables of different specifications and having a wide range of applications.

[0044] (3) The present invention ensures the stability of the unwinding process of the wire feeding wheel 4 by using the first slider 9 in conjunction with the groove 7.

[0045] (4) By using the first electric push rod 12, the pressure claw 13 and the pressure roller 14 together, this utility model can ensure that the wire feeding wheel 4 feeds the wire in an orderly manner, thereby avoiding the messy phenomenon of the cable to be tested during the unwinding process.
