Description

Technical Field

[0001] The utility model relates to the field of wire rope manufacturing equipment, and specifically, to a wire monitoring device for a wire wheel. Background Art

[0002] When twisting a wire rope, multiple wire wheels wound with wires are installed in the wire rack inside the barrel of the stranding machine. The wires are led out through the wire threading nozzles of the wire distributing plate behind the barrel. Through the rotation of the barrel, passing through the wire pressing die, the wires are twisted into wire ropes with different lay lengths according to different process requirements. During stranding, thin wires are continuously released from the wire wheels. When the thin wires on the wire wheels are nearly released, the machine must be stopped to replace the wire wheels. Currently, there is no automatic detection device or method for whether the wires are nearly released. Generally, workers observe in real time, resulting in high labor intensity.

[0003] The utility model patent with the authorization announcement number CN218629507U discloses a broken wire monitoring device for a stranding machine, including a wire distributing plate fixed at one end of the stranding machine. Alarm lights and monitoring switches equal in number to the wire threading openings are arranged on the circumferential side of the wire distributing plate, and a monitoring mechanism for monitoring the broken wire condition of the wires is arranged on the inner wall of the wire threading opening. This broken wire monitoring device for the stranding machine monitors the movement state of the wires in the wire threading opening by setting an installation sleeve, a support rod, a pressure switch, a diffuse reflection photoelectric switch, and a diffuse reflection plate. Specifically, as long as one pressure switch in the wire threading opening is not squeezed, it means there is a wire in this wire threading opening. When multiple diffuse reflection photoelectric switches in a wire threading opening sequentially produce diffuse reflection with the diffuse reflection plate, it means there is a wire passing through. If only one diffuse reflection photoelectric switch produces diffuse reflection with the diffuse reflection plate, it means the guide rollers do not rotate, and the wire is broken after passing through the wire threading opening. However, this device cannot be directly applied to monitor whether the thin wires on the wire wheel are nearly released. Content of the Utility Model

[0004] In order to monitor the thin wires on the wire wheel and give an early warning when the thin wires are nearly released, the technical solution adopted by the utility model is: a wire monitoring device for a wire wheel, including a probe cantilever support mechanism, a probe, a wire wheel rotating shaft, and a pair of magnets;

[0005] A pair of the magnets are arranged on the wire wheel rotating shaft and distributed along the length direction of the wire wheel rotating shaft for the probe to sense;

[0006] The probe cantilever support mechanism is arranged beside the wire wheel rotating shaft for supporting the probe and elastically pressing the probe on the wire wheel rotating shaft;

[0007] The detection head is installed at the suspended end of the detection head cantilever support mechanism, and is used to sense a pair of the magnets and generate an induction signal when simultaneously sensing a pair of magnets.

[0008] Based on the above, in order to ensure that the detection head cantilever support mechanism can always press on the steel wires of the wire wheel, the detection head cantilever support mechanism includes a slewing frame base, a slewing frame, and a probe support;

[0009] The bottom end of the slewing frame is connected to the slewing frame base through a rotating shaft, the probe support is installed at the top end of the slewing frame, the detection head is installed on the lower surface of the probe support, rollers are installed on both sides of the probe support, and a spring is installed between the lower end of the slewing frame and the slewing frame base.

[0010] That is, the top end of the slewing frame is pressed on the surface of the steel wire on the wire wheel shaft by the elastic force of the spring. Due to the existence of the rollers, the rollers will first contact the steel wire on the wire wheel shaft and rotate with the steel wire shaft, changing the sliding friction to rolling friction and reducing the friction force. At the same time, the detection head installed on the slewing frame is lifted by the rollers, so that the detection head is separated from the steel wire on the wire wheel shaft to avoid scratching the detection head.

[0011] Based on the above, in order to facilitate the adjustment of the installation position of the detection head, a strip-shaped hole for installing the probe support is opened at the top of the slewing frame, and the probe support can be adjustably installed on the slewing frame.

[0012] Based on the above, in order to facilitate the detection head to sense the magnets, the detection head and a pair of the magnets are arranged correspondingly.

[0013] Based on the above, in order to enable the detection head to detect two magnet signals before the steel wire on the wire wheel is completely emptied, and to ensure that the remaining amount of the steel wire on the wire wheel is controlled within a reasonable range, a pair of the magnets are symmetrically arranged with the center of the wire wheel shaft as the axis of symmetry.

[0014] That is, when the steel wire is wound on the wire wheel, it is usually wound from the middle part of the wire wheel shaft and then alternately moves back and forth to both sides for winding. Then, when the steel wire is released from the wire wheel, the steel wire in the middle of the wire wheel shaft is released last. Therefore, when the detection head simultaneously senses the magnets on both sides when the steel wire is released from the wire wheel, there will still be a certain length of steel wire remaining in the middle of the wire wheel shaft, thus avoiding the emptying phenomenon caused by the complete release of the steel wire rope from the wire wheel shaft and effectively avoiding the phenomena of lack of wire and broken wire in the stranding machine.

[0015] Based on the above, in order to facilitate the fixing and installation of the spring, the slewing frame base is a U-shaped slewing frame base, and the width value of the bottom end of the slewing frame is smaller than the width value of the inner groove of the U-shaped slewing frame base.

[0016] Based on the above, the length value of the probe bracket is less than the length value of the wire wheel rotating shaft.

[0017] Based on the above, in order to facilitate the detection head to promptly sense the magnet after the steel wire rope is emptied from the surface of the magnet, the magnet is a bar magnet. The detection width of the detection head is greater than the distance between two bar magnets.

[0018] The utility model has substantial features and progress compared with the prior art. Specifically, the steel wire wheel steel wire monitoring device provided by the utility model installs a pair of magnets at different positions of the wire wheel rotating shaft, and rotatably arranges a rotary frame beside the wire wheel, and installs a detection head for sensing the magnet on the rotary frame. Thus, when the steel wire wound on the wire wheel is nearly used up, the magnet is exposed from the wire wheel rotating shaft, so that the detection head can detect the position of the magnet, and then send a signal of detecting the magnet to the control device, indicating that the thin steel wire on the wire wheel is nearly released. Thus, it realizes the monitoring of the thin steel wire on the wire wheel and automatically gives an early warning when the thin steel wire is nearly released.

[0019] Furthermore, by pulling a spring at the bottom of the rotary frame and installing rollers on both sides of the rotary frame, the probe can be attached to the upper part of the wire wheel rotating shaft by using the spring, and the rotary frame is in rolling contact with the wire wheel rotating shaft, reducing friction.

[0024] The following further describes the technical solutions of the present utility model in detail through specific embodiments.

[0025] Embodiment 1

[0026] This embodiment provides a steel wire wheel steel wire monitoring device, such as Figure 1 , Figure 2 , Figure 3As shown, it includes a probe head cantilever support mechanism, a probe head 9, a wire wheel rotating shaft 1, and a pair of magnets 4. Among them, in this embodiment, the magnets are selected as common strong magnets.

[0027] A pair of the magnets 4 are arranged on the wire wheel rotating shaft 1 and distributed along the length direction of the wire wheel rotating shaft 1 for the probe head 9 to sense.

[0028] The probe head cantilever support mechanism is arranged beside the wire wheel rotating shaft 1 for supporting the probe head 9 and elastically pressing the probe head 9 on the wire wheel rotating shaft 1.

[0029] The probe head 9 is installed at the suspended end of the probe head cantilever support mechanism for sensing a pair of the magnets 4 and generating an induction signal when simultaneously sensing a pair of magnets 4.

[0030] Specifically, as Figure 1 shown, in order to ensure that the probe head cantilever support mechanism can always press on the steel wire of the wire wheel, the probe head cantilever support mechanism includes a slewing frame base 8, a slewing frame 6, and a probe holder 3.

[0031] The bottom end of the slewing frame 6 is connected to the slewing frame base 8 through a rotating shaft 7. The probe holder 3 is installed at the top end of the slewing frame 6. The probe head 9 is installed on the lower surface of the probe holder 3. Rollers 2 are installed on both sides of the probe holder 3. A spring 10 is installed between the lower end of the slewing frame 6 and the slewing frame base 8.

[0032] Specifically, when the probe head simultaneously senses a pair of magnets, an induction signal is generated, and this induction signal will subsequently be transmitted to the wire stranding machine control center so that the operator or the automatic control center can reasonably control the rotation speed and start / stop state of the wire stranding machine according to actual needs.

[0033] Embodiment 2

[0034] This embodiment provides a steel wire wheel steel wire monitoring device. The main difference from Embodiment 1 is that in this embodiment, as shown in Fig. 1, in order to facilitate adjusting the installation position of the probe head 9, a strip-shaped hole 5 for installing the probe holder 3 is opened at the top of the slewing frame 6. The probe holder 3 can be adjustably installed on the slewing frame 6.

[0035] Embodiment 3

[0036] This embodiment provides a steel wire monitoring device for a steel wire wheel. The main difference from Embodiment 1 is that in this embodiment, in order to facilitate the detection head to sense the magnet, the detection head 9 and a pair of the magnets 4 are arranged correspondingly. In order to enable the detection head to detect the signals of two magnets before the steel wires on the steel wire wheel are completely emptied, and to ensure that the remaining amount of the steel wires on the steel wire wheel is controlled within a reasonable range, a pair of the magnets 4 are symmetrically arranged with the center of the steel wire wheel rotating shaft 1 as the axis of symmetry.

[0037] That is, when winding the steel wires on the steel wire wheel, it is usually started from the middle part of the steel wire wheel rotating shaft and then wound alternately back and forth on both sides. Then, when the steel wires are released from the steel wire wheel, the steel wires in the middle of the steel wire wheel rotating shaft are released last. Therefore, when the detection head simultaneously senses the magnets on both sides when the steel wires are released from the steel wire wheel, there will still be a certain length of steel wires remaining in the middle of the steel wire wheel rotating shaft, thus avoiding the emptying phenomenon caused by the complete release of the steel wire rope from the steel wire wheel rotating shaft and effectively avoiding the wire breakage and lack of wire phenomena of the stranding machine.

[0038] Embodiment 4

[0039] This embodiment provides a steel wire monitoring device for a steel wire wheel. The main difference from Embodiment 1 is that in this embodiment, in order to facilitate the fixing and installation of the spring, the rotary frame base 8 is a U-shaped rotary frame base. The width value of the bottom end of the rotary frame 6 is smaller than the width value of the inner groove of the U-shaped rotary frame base. The length value of the probe bracket 3 is smaller than the length value of the steel wire wheel rotating shaft 1. In order to facilitate the detection head to sense the magnet in time after the steel wire rope is emptied from the surface of the magnet, the magnet 4 is a bar magnet.
