Description

Technical Field

[0001] The invention belongs to the technical field of steel wire rope manufacturing, and in particular relates to a device and a method for measuring the roller end distance and bending amount of a strand rope pre-deformer. Background Art

[0002] Steel wire rope is made of several strands twisted around a rope core. When twisting the rope, it is necessary to use a suitable strand pre-deformer to pre-twist the strands. There are strict process requirements for the roller end distance and strand bending amount of the strand pre-deformer to ensure that the spiral line formed after the strand pre-deformation is consistent with the spiral line of the strand inside the steel wire rope, so as to achieve the best twisting state and non-loose performance. At present, the industry generally uses a three-stage adjustable conical pre-deformer. The distance between the deformation rollers is adjusted by the left and right threads on the hollow shaft, and the strand bending amount is adjusted by rotating the middle disk. When actually adjusting and measuring the process parameters of the strand pre-deformer, a tape measure is generally used for measurement, which has a large measurement error. In particular, the measurement of the strand bending amount has no reference benchmark and is only estimated by the naked eye, which seriously affects the adjustment of process parameters and the twisting quality of the product.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1-Figure 3 The present invention provides a device for measuring the roller end distance and bending amount of a strand pre-deformer, comprising:

[0028] Horizontal main board 15;

[0029] The roller end distance measuring assembly includes a starting point stopper fixedly connected to the transverse main board 15 and an end point stopper slidably connected to the transverse main board 15. A distance measuring member is also provided on the transverse main board 15. The distance measuring member is used to measure the distance between the starting point stopper and the end point stopper. The starting point stopper, the end point stopper and the distance measuring member are respectively provided corresponding to the first wire roller rotating shaft 12 and the second wire roller rotating shaft 14.

[0030] The bending measurement component includes a longitudinal ruler 5, which is slidably connected to the transverse main board 15 through a position adjustment member. The longitudinal ruler 5 is vertically arranged to the transverse main board 15, and is used to measure the distance between an intermediate wire roller shaft 13 and a distance measuring member.

[0031] The main function of the starting point limiter and the end point limiter is to abut between the first wire roller shaft 12 and the second wire roller shaft 14, so as to mark the distance between the first wire roller shaft 12 and the second wire roller shaft 14; the main function of the distance measuring member is to directly measure the distance between the starting point limiter and the end point limiter, so as to obtain the roller end distance; the main function of the longitudinal ruler 5 is to measure the distance between the intermediate wire roller shaft 13 located above the distance measuring member and the distance measuring member, so as to obtain the bending amount; the main function of the position adjusting member is to adjust the position of the longitudinal ruler 5 after the position of the transverse main board 15 is fixed, so as to facilitate the measurement. On the whole, by using the device for measuring the roller end distance and the bending amount of the strand rope predeformer of the present invention for measurement, the operation method is simple, the roller end distance and the bending amount can be measured almost synchronously, the measurement efficiency is high, the practicability is strong, and the data measurement is intuitive and accurate.

[0032] According to a further optimized solution, the starting point limiter includes a starting point measuring rod 1 , which is fixedly connected to one end of the transverse main board 15 , and the starting point measuring rod 1 is vertically arranged to the transverse main board 15 .

[0033] like Figure 1 As shown, the starting point measuring rod 1 is fixedly connected to the left end of the transverse main board 15 by bolts.

[0034] According to a further optimized solution, a slideway 2 is provided on the transverse main board 15 along the length direction of the transverse main board 15 , and the position adjustment member and the end point limit member are slidably arranged in the slideway 2 .

[0035] A further optimized solution is that the end point limiter includes an end point measuring rod 6 slidably connected in the slide 2, the end point measuring rod 6 is vertically arranged with the horizontal main board 15, and a lifting eye screw 7 is arranged on the end point measuring rod 6, the lifting eye screw 7 is arranged corresponding to the slide 2, and the lifting eye screw 7 is used to fix the end point measuring rod 6 in the slide 2.

[0036] like Figure 1 and Figure 2 As shown, the threaded end of the eye screw 7 passes through the slideway 2 and is threadedly connected to the end point measuring rod 6, so that the end point measuring rod 6 can slide freely along the slideway 2.

[0037] To further optimize the solution, a handle 9 is fixedly connected to one end of the horizontal main board 15 close to the starting point measuring rod 1, and a tension spring 8 is fixedly connected between the handle 9 and the eye screw 7.

[0038] like Figure 2 and Figure 3 As shown, the main function of the handle 9 is to facilitate the measurement personnel to hold the horizontal main board 15. At the same time, when the starting point measuring rod 1 is in contact with the left end of the first wire roller shaft 12 on the left, and the end point measuring rod 6 moves to be in contact with the right end of the second wire roller shaft 14 on the right, the tension spring 8 can automatically pull the end point measuring rod 6 to be close to the right side of the second wire roller shaft 14 through its own tension, thereby reducing the difficulty of operation and improving the measurement accuracy.

[0039] A further optimized solution is that the distance measuring component includes a transverse ruler 3, which is fixedly connected to the transverse main board 15, and the zero mark of the transverse ruler 3 is aligned with the side of the starting point measuring rod 1 close to the end point measuring rod 6. The top of the transverse ruler 3 is arranged corresponding to the bottom of the first wire roller shaft 12 and the second wire roller shaft 14. The transverse ruler 3 is used to measure the distance between the end point measuring rod 6 and the starting point measuring rod 1.

[0040] like Figure 1 and Figure 3 As shown, during measurement, the top of the transverse ruler 3 should be in contact with the bottom of the first wire roller shaft 12 and the second wire roller shaft 14, providing a reference for the data measurement of the longitudinal ruler 5. At the same time, since the zero scale line of the starting point measuring rod 1 coincides with the zero scale line of the transverse ruler 3, the scale value corresponding to the side wall of the end point measuring rod 6 close to the starting point measuring rod 1 and the transverse ruler 3 is the distance between the starting point measuring rod 1 and the end point measuring rod 6.

[0041] A further optimized solution is that the position adjustment member includes a slider 4, which is slidably connected in the slide 2. A first screw 10 is provided on the slider 4. The first screw 10 is provided corresponding to the slide 2. The first screw 10 is used to fix the position of the slider 4 in the slide 2. The longitudinal measuring ruler 5 is provided on the slider 4.

[0042] like Figure 1 and Figure 2 As shown, the threaded end of the first screw 10 passes through the slideway 2 and is threadedly connected to the slider 4. When the slider 4 drives the longitudinal measuring ruler 5 to move to a suitable position, the first screw 10 is tightened to make the first screw 10 fit tightly with the transverse main board 15, thereby fixing the position of the slider 4.

[0043] A further optimized solution is that a slot 16 is vertically opened on the side wall of the slider 4, and openings are respectively provided on both sides of the slot 16. The longitudinal ruler 5 is slidably connected in the slot 16, and a second screw 11 is provided on one side of the slot 16. The threaded end of the second screw 11 passes through the slot 16 and is provided corresponding to the side wall of the longitudinal ruler 5.

[0044] like Figure 2 As shown, when the second screw 11 is not tightened, the longitudinal ruler 5 can slide up and down in the slot 16. When the longitudinal ruler 5 moves to the point where the top zero mark fits in with the top of the intermediate wire roller shaft 13 with measurement, the second screw 11 is tightened so that the second screw 11 squeezes the longitudinal ruler 5 into the slot 16, thereby fixing the longitudinal position of the longitudinal ruler 5.

[0045] A method for measuring the roller end distance and bending amount of a strand pre-deformer, the operating steps comprising:

[0046] The distance measuring member is placed on the bottom of the first wire roller shaft 12 and the second wire roller shaft 14, the starting point stopper is placed against the side of the first wire roller shaft 12 away from the second wire roller shaft 14, and the end point stopper is moved so that the end point stopper is placed against the side of the second wire roller shaft 14 away from the first wire roller shaft 12;

[0047] The surveyor holds the handle 9 and fits the starting point measuring rod 1 to the left side of the first wire roller shaft 12 on the left side. At the same time, the end point measuring rod 6 is pulled to fit the right side of the second wire roller shaft 14 on the right side. At this time, the tension spring 8 is stretched, and the end point measuring rod 6 can automatically fit the right side of the second wire roller shaft 14 under the tension of the tension spring 8. After that, the top of the horizontal measuring ruler 3 is fit to the bottom of the first wire roller shaft 12 and the second wire roller shaft 14 through the handle.

[0048] The position of the longitudinal measuring ruler 5 is moved by the position adjusting member so that the zero mark on the top of the longitudinal measuring ruler 5 is in contact with the bottom of an intermediate wire roller shaft 13;

[0049] Loosen the first screw 10 and adjust the slider 4 so that the longitudinal ruler 5 is close to the middle wire roller shaft 13. Then tighten the first screw 10 and loosen the second screw 11 to adjust the vertical position of the longitudinal ruler 5 so that the zero mark on the top coincides with the bottom of the middle wire roller shaft 13 located above the transverse ruler 3 and closest to the transverse ruler 3.

[0050] The distance between the starting point limiter and the end point limiter is measured by the distance measuring piece, thereby determining the roller end distance, and the distance between the intermediate conductor roller shaft 13 and the distance measuring piece is measured by the longitudinal measuring ruler 5, thereby determining the bending amount.

[0051] The roller end distance can be calculated by the scale of the side wall of the end measuring rod 6 close to the starting measuring rod 1 and the horizontal measuring ruler 3, and the compression amount can be calculated by the scale of the top of the horizontal measuring ruler 3 and the vertical measuring ruler 5.

[0052] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0053] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
