Description

Technical Field

[0001] This utility model relates to the field of wire length measurement technology, and in particular to a steel strand wire length measurement device. Background Technology

[0002] In the production and application of steel strands, the accurate control of steel strand length measurement has always been a challenge. For example, when steel strands are used to fix meteorological towers, the length of the steel strands needs to be pre-set according to the length of the meteorological tower, and the length of steel strands used for different fixing parts of the meteorological tower is different. In the prior art, when measuring and bundling steel strands on demand, the ends of the bundled steel strands need to be led out to the clamping assembly to straighten the steel strands, and then the length of the steel strands is measured by a rotary encoder and a counter. Finally, the strands are rewound by a winding roller connected to a rotary power device, and the rewound length is mainly determined by the length calculated by the rotary encoder and the counter. For example, the utility model patent with application number CN202123271967.8 provides a meter counting device for bundling steel strands, which records the length of the steel strands by setting a rotary encoder, a limit reel, and a counter. When the limit reel rotates, the rotary encoder records the number of rotations and displays it through the counter to obtain the length of the steel strands. However, it has the following problems when in use: relative slippage may occur between the steel strand and the limit reel, and the fit between the steel strand and the limit reel may not be high. In this case, the length of the steel strand calculated by the number of rotations recorded by the rotary encoder is inaccurate.

[0003] To solve the above problems, a new type of steel strand length measuring device is needed. Summary of the Invention

[0020] Example

[0021] like Figure 1-3 As shown, a steel strand length measuring device includes a measuring component and a rewinding component arranged sequentially. The measuring component includes a measuring bracket 1, with a first support rod 2 and a second support rod 3 arranged in parallel between two side plates of the measuring bracket 1. A first pair of rollers 4 and a second pair of rollers 5 are vertically arranged on the first support rod 2 and the second support rod 3, respectively. The first pair of rollers 4 and the second pair of rollers 5 are detachably connected to the first support rod 2 and the second support rod 3, respectively, facilitating replacement of the first pair of rollers 4 and the second pair of rollers 5. The first pair of rollers 4 is located on the side of the second pair of rollers 5 away from the rewinding component, and the outer walls of both the first pair of rollers 4 and the second pair of rollers 5 are fixedly connected to rubber sleeves. The rubber sleeves increase the friction between the steel strand and the first pair of rollers 4 and the second pair of rollers 5, preventing slippage. The two rotating rollers of the first pair of rollers 4 are each connected to a rotary encoder 6, and both rotary encoders 6 are connected to counters. The counters are connected to the calculation module of the controller, and the controller is connected to the rewinding power device of the rewinding component.

[0022] In use, both the first pair of rollers 4 and the second pair of rollers 5 clamp the steel strand, so that when the steel strand is conveyed forward, it can drive the rotating rollers on the first pair of rollers 4 and the second pair of rollers 5 to rotate. The second pair of rollers 5 is used to maintain the stability of the steel strand's conveying path, preventing the steel strand from shifting due to excessive winding thickness on the slitting assembly, which could cause relative slippage between the steel strand and the first pair of rollers 4 and affect the accuracy of the rotary encoder 6 in measuring the length of the steel strand.

[0023] The slitting assembly includes a base 7, the top surface of which is provided with a rotating frame 8 connected to a slitting power unit. A slitting reel 9 is mounted on the rotating frame 8. Symmetrically arranged lifting rings 10 are provided on the top surface of the slitting reel 9, allowing a crane to easily place the slitting reel 9 onto the rotating frame 8, saving manpower. The slitting reel 9 includes a connecting part and a winding part integrally formed from top to bottom. The connecting part is detachably connected to the rotating frame 8 via a connector 11, which facilitates the disassembly of the slitting steel strand. The side wall of the winding part has a groove 12 for winding the steel strand, which can collect and protect the slitting steel strand, preventing wear during transportation. The top surface of the winding part has a through hole, within which a fixing rod 13 is installed. The fixing rod 13 is used to fix the end of the steel strand to the slitting reel 9, preventing slippage between the steel strand and the slitting reel 9 during winding. The top surface of the winding section is provided with symmetrically arranged buckle plates 14. The connecting end of the buckle plate 14 is connected to the slitting reel 9 via a rotating shaft, and the movable end of the buckle plate 14 is detachably connected to the bottom surface of the slitting reel 9 via bolts. After the movable end of the buckle plate 14 is connected to the bottom surface of the slitting reel 9, the buckle plate 14 can limit the steel strand in the slitting reel 9, preventing the tail end of the steel strand after slitting from coming out of the slitting reel 9.

[0024] The rotating frame 8 includes a connecting plate 81, the bottom surface of which is connected to the output shaft of the slitting power device, which drives the rotating frame 8 to rotate. A ring 82 is provided around the connecting plate 81, and the ring 82 and the connecting plate 81 are fixedly connected by multiple connecting rods 83. A support rod 84 is provided on the connecting rod 83, comprising a vertical section and an inclined section arranged vertically. The bottom end of the inclined section is fixedly connected to the connecting rod 83. The vertical distance from the inclined section to the vertical line where the output shaft of the slitting power device is located gradually decreases from bottom to top. The inclined section supports the bottom surface of the slitting reel 9, ensuring the stability of the slitting reel 9. A threaded hole 85 adapted to the structure of the connecting piece 11 is provided on the vertical section. The threaded hole 85 is used to cooperate with the connecting piece 11 on the slitting reel 9, firmly fixing the slitting reel 9 to the rotating frame 8.

[0025] Before use, select appropriate thicknesses for the first pair of rollers 4 and the second pair of rollers 5 and install them on the metering bracket 1. This ensures that when the steel strand passes through the first pair of rollers 4 and the second pair of rollers 5, the steel strand can rotate with the rotating rollers on the first pair of rollers 4 and the second pair of rollers 5 without slipping. During use, first fix the slitting reel 9 on the rotating frame 8. Then, pull the ends of the bundled steel strands from the clamping assembly in the prior art to ensure the straightness of the steel strands. Next, pass the steel strands sequentially through the first pair of rollers 4 and the second pair of rollers 5 and fix them to the fixing rod 13 on the slitting reel 9. Then, start the slitting power device, so that the rotating frame 8 and the slitting reel 9 can rotate under the drive of the slitting power device to achieve the slitting and winding of the steel strands. When the steel strand passes through the first pair of rollers 4 and the second pair of rollers 5, it will drive the rotating rollers on the first pair of rollers 4 and the second pair of rollers 5 to rotate. Two rotary encoders 6 sense... The number of rotations of the two rotating rollers on the first pair of rollers 4 is transmitted to the calculation module of the controller via a counter. The calculation module first determines whether the two rotation counts are consistent. If they are inconsistent, it checks whether the first pair of rollers 4 clamps the steel strand. If they are consistent, it obtains the passing length of the steel strand by multiplying the number of rotations by the cross-sectional circumference of the rotating roller. By comparing the passing length with the preset winding length, it determines whether to control the winding power device to stop winding. The second pair of rollers 5 ensures the stability of the steel strand's conveying path at the first pair of rollers 4, thereby ensuring the accuracy of measuring the winding length of the steel strand using the rotary encoder 6. After the winding power device stops winding and cuts the steel strand, the movable end of the buckle plate 14 is fixed, and then the connector 11 is loosened. The entire winding reel 9 is then removed from the rotating frame 8 using the lifting ring 10.

[0026] Therefore, the present invention provides a steel strand length measuring device with the above-mentioned structure, which effectively improves the accuracy of length measurement when steel strands are rewound, and at the same time facilitates the disassembly of the rewound steel strands.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
