Description

Technical Field

[0001] This utility model relates to the field of wire rope distance measurement technology, specifically a wire rope distance measurement device. Background Technology

[0002] In port operations, steel wire ropes of varying lengths need to be cut for hoisting, binding, fixing, and connecting. When the cut length is short, tools such as a measuring tape can be used for measurement. However, when the cut length is long, the steel wire rope needs to be stretched straight and laid flat, and the length is measured along the rope using a long measuring tape or measuring wheel. The length is then added up after marking the sections. This method greatly increases the labor intensity of workers. Therefore, the roller counting method is often used. The length is calculated by the number of rotations of the roller (length = roller circumference × number of rotations). A rotation counter is installed to record the length of the steel wire rope in real time. The roller can be set at the take-up end and rotate with the take-up motor; it can also be set at the path of the steel wire rope, where the friction of the steel wire rope drives the roller to rotate and achieve measurement.

[0003] However, the following problems exist when using existing wire rope distance measuring devices: 1. When the drum is set at the take-up end, the wire rope will stack when winding, resulting in the actual drum circumference becoming longer during measurement; 2. When the drum is set at the wire rope's movement path, the surface of the wire rope is often coated with anti-rust oil, making it difficult to obtain sufficient friction, causing the wire rope to slip when passing the drum, resulting in the drum not rotating synchronously. All of the above measurement methods will lead to inaccurate wire rope distance measurement. Utility Model Content

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] See Figure 1-7 As shown, a wire rope 2 ranging device includes a wire storage frame 3, a base 11, and a take-up frame 9, which are fixed to the ground in sequence. The wire storage frame 3 is wound with wire rope 2. The wire rope 2 is located above the base 11, and one end of the wire rope 2 is connected to the take-up frame 9. The wire storage frame 3 is rotatably connected to a wire release roller 301. One end of the wire rope 2 is wound around the wire release roller 301, and the other end of the wire rope 2 is fixed to the take-up roller 901. The take-up roller 901 is rotatably connected to the take-up frame 9. A winding motor 8 is fixed above the take-up frame 9. The output end of the winding motor 8 passes through the upper part of the take-up frame 9 and is fixedly connected to the take-up roller 901. The winding motor 8 is used to take in the wire rope 2. The upper surface of the base 11 is fixed with a first limiting roller 4, a counting structure 5, and a second limiting roller 7 in sequence from the wire storage frame 3. The wire rope 2 passes through the first limiting roller 4, the counting structure 5, and the second limiting roller 7 in sequence. The counting structure 5 includes a rotating plate 1, a rotating sleeve 501, a magnetic block 503, a rotating frame 504, and a Hall sensor 10. The rotating plate 1 has a central hole, and the steel wire rope 2 is slidably connected to the rotating plate 1. The rotating plate 1 is inserted and fixed to the rotating sleeve 501, and the rotating sleeve 501 is rotatably connected to the rotating frame 504. The Hall sensor 10 is fixed on the side of the rotating frame 504 near the magnetic block 503. The magnetic block 503 is fixed on the side of the rotating sleeve 501 near the edge of the arc surface. The minimum distance between the magnetic block 503 and the Hall sensor 10 is 1-5mm, which is adjusted according to the sensitivity of the Hall sensor 10 to ensure stable measurement.

[0027] like Figure 5As shown in this embodiment of the present invention, there are two magnetic blocks 503, symmetrically arranged at the rotation center of the rotating sleeve 501, and with opposite polarities; a balance block 502 is fixed to the side plane of the rotating sleeve 501 that fixes the magnetic blocks 503. The balance block 502 has the same mass as the magnetic blocks 503. There are multiple balance blocks 502, which are evenly arranged in a circumferential shape with the magnetic blocks 503 to avoid eccentricity during rotation and cause additional wear. The balance block 502 is made of ceramic material to avoid interference with the Hall sensor 10. The magnetic blocks 503 can be made of 5mm neodymium iron boron magnets.

[0028] The above embodiments all enable the Hall sensor 10 to generate pulses. Pulse counting of the Hall sensor 10 is a common technique. The Hall sensor 10 is readily available, model YS-27 / 3144E Hall sensor 10 module, which integrates a Hall effect chip, voltage regulator, reverse voltage protector, signal amplification and processing circuit, Schmitt trigger, and an open-collector output driver transistor. In addition, the LM393 operational amplifier chip on the Hall sensor 10 module is used to shape the analog signal generated by the ES3144 Hall sensor 10 into a digital square wave signal, which can be directly connected to the microcontroller interrupt for counting. This will not be described in detail here.

[0029] In the operation of this embodiment, when a count is performed, that is, the rotating sleeve 501 rotates one revolution, the required number of revolutions can be obtained by dividing the required length of the wire rope 2 by the lay pitch. After the required number of revolutions is reached, the winding motor 8 is turned off.

[0030] like Figure 3 , Figure 5 and Figure 6 As shown in this embodiment of the present invention, the rotating plate 1 includes positioning holes 101 and guide grooves 102. The guide grooves 102 are evenly distributed on the inner annular surface of the rotating plate 1.

The groove opening of the guide groove 102 is in contact with the outer edge of a single strand of the wire rope 2. There are multiple positioning holes 101, which are opened on the plane of the rotating plate 1 and located outside the central through hole of the rotating plate 1. The rotating sleeve 501 is fixed with a pin inserted into the positioning hole 101 on the side facing the rotating plate 1. The guide groove 102 has an arc surface in cross section, which shrinks from the upper and lower planes towards the center to reduce the friction of the wire rope 2 passing through the rotating plate 1.

[0031] Furthermore, in this embodiment, the wire rope 2 is transferred from the insertion side of the rotating plate 1 to the take-up frame 9 to prevent the rotating plate 1 from coming loose.

[0032] By changing the rotating disc 1 of different specifications, measurements can be taken on steel wire ropes 2 of different specifications and number of strands.

[0033] like Figure 7As shown in this embodiment of the present invention, a locking structure 6 is fixed on the upper surface of the base 11.

The locking frame 601 has a central through hole, into which the steel wire rope 2 is inserted. The locking block 602 is vertically inserted into the locking frame 601. The locking block 602 has an I-shaped cross-section. A spring is fixedly connected between the bottom surface of the locking block and the sliding groove inside the locking frame. The pressure block 603 is fixed to the top of the locking block 602. The above structure is used to fix the steel wire rope 2 by pressing the pressure block 603.

[0034] In the operation of this embodiment, after the required number of revolutions is reached, the winding motor 8 is turned off, the pressure block 603 is stepped on, and the wire rope scissors are used to cut the wire rope 2 at the counting structure 5 to prevent it from shifting during the cutting process.

[0035] like Figure 7 As shown, in another embodiment of this utility model, the bottom end of the locking block 602 is provided with a cutting blade. The steel wire rope 2 is cut by hammering the pressing block 603, eliminating the need to cut the steel wire rope and reducing the tools required.

[0036] like Figure 4 As shown in this embodiment of the present invention, the first limiting roller 4 and the second limiting roller 7 have the same structure, including a limiting roller frame 401, a positioning bolt 402 and a limiting roller body 403. The limiting roller frame 401 is fixed to the upper surface of the base 11. The limiting roller frame 401 is slidably connected to two positioning bolts 402. The limiting roller body 403 is rotatably connected to the positioning bolts 402. The wire rope 2 is inserted between the two limiting roller bodies 403 for adjustment according to the size of the wire rope 2, so that the wire rope 2 is transmitted on the same plane.

[0037] In the operation of this embodiment, the position of the positioning bolt 402 is fixed by adjusting the tightness of the nut of the positioning bolt 402, thereby adjusting the guide of the wire rope 2 according to the size of the wire rope 2 to reduce friction. The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
