Description

Technical Field

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

[0002] In various types of equipment that use ropes for fixation, traction, or load-bearing, rope clamps are used to secure the ropes. If a rope clamp shifts, the rope's securing force will decrease, potentially causing the rope to loosen or even fall off. For example, in the hoisting mechanism of a crane, the wire rope is secured to the drum or hook by a rope clamp. If the rope clamp shifts and causes the wire rope to loosen, it could lead to serious safety accidents such as the falling of heavy objects, causing equipment damage and personal injury.

[0003] Rope clamp displacement can cause uneven stress on the rope during operation, resulting in additional impact and wear on the equipment components connected to the rope. For example, in an elevator traction system, rope clamp displacement may alter the frictional distribution between the wire rope and the traction sheave, accelerating wear on the traction sheave, shortening the equipment's service life, and affecting the safe operation of the elevator. Currently, monitoring the displacement of rope clamps mainly relies on regular manual inspections. This method is not only inefficient but also makes it difficult to detect minute displacement changes in a timely manner. In complex working environments, such as high altitudes, high temperatures, and humidity, manual inspections are even more difficult and may even pose safety risks. Therefore, this application provides a rope clamp displacement device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rope clamp displacement device, which solves the problem that the displacement of rope clamps in existing technologies mainly relies on manual periodic inspection. This method is inefficient, makes it difficult to detect minute displacement changes in a timely manner, and poses safety risks in complex working environments such as high altitude, high temperature, and humidity.

[0005] The rope clamp displacement device of this utility model includes a weighing steel wire rope and a rope clamp set on the steel wire rope, wherein the rope clamp is used to fix the steel wire rope. The wire rope includes dead wires and live wires, the live wires and dead wires are arranged symmetrically and fixed by rope clips; A sensor is also provided on the outside of the dead wire, and a mounting base is provided at the bottom of the sensor. The mounting base is located on one side of the rope clamp and is used to detect the displacement of the rope clamp. There are two sensors, which are located on both sides of the rope clamp and are used to detect the forward and reverse displacement of the rope clamp.

[0006] As a further improvement of this utility model, the mounting base includes two support plates, which are symmetrically arranged and form a clamping area for fixing the dead wire, thereby fixing the sensor.

[0007] As a further improvement of this utility model, a vertical detection plate is provided on one side of the top of one of the support plates. The vertical detection plate is perpendicular to one side of the support plate, and one side of the vertical detection plate is planar and adapted to the sensor.

[0008] As a further improvement of this utility model, both sides of the support plate are provided with protrusions, and the top of the protrusions has two positioning holes, and they are adapted to the other support plate by fasteners to fasten the clamping area.

[0009] As a further improvement of this utility model, the bottom of the support plate is provided with an arc-shaped groove, and the arc-shaped groove is provided with protrusions arranged in a ring array, with a slot formed between every two protrusions.

[0010] As a further improvement of this utility model, a filler is installed on the inner side of the slot, and one side of the filler that contacts the dead wire is roughened to increase the friction between the clamping area and the dead wire.

[0011] As a further improvement of this utility model, the bottom of the two protrusions is respectively provided with a locking block and a docking groove, and the two sets of locking blocks and docking grooves are staggered.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by placing two sensors on both sides of the rope clamp, can detect the forward and reverse displacement of the rope clamp in real time and comprehensively. Compared with manual periodic inspection, it can detect small displacement changes of the rope clamp in time, avoiding serious consequences such as rope loosening and wear of equipment parts due to displacement accumulation. The sensor is fixed to the outside of the dead wire by the mounting base, which ensures the stability of the sensor installation. Two symmetrically arranged support plates form a clamping area to fix the dead wire. The vertical detection plate provides an adaptation plane for the sensor, ensuring that the sensor can accurately sense the displacement of the rope clamp. Moreover, the protrusions, positioning holes and fasteners cooperate to tighten the support plate to secure the dead wire, further ensuring the reliability of the sensor detection. Meanwhile, the filler installed inside the slot has a rough surface on the side that contacts the dead wire, which greatly increases the friction between the clamping area and the dead wire. This effectively prevents the dead wire from sliding during equipment operation, ensures that the dead wire is firmly fixed in the clamping area, improves the fixing effect of the rope clamp on the wire rope, and reduces the risk of rope clamp displacement. Furthermore, the locking block and the mating groove at the bottom of the convex strip are staggered, which can guide the two support plates to be accurately aligned during installation, so that the dead wire is subjected to uniform force. After the locking block is embedded in the mating groove, it enhances the connection strength between the support plates and prevents the relative displacement of the support plates due to equipment vibration, further ensuring the fixing effect of the mounting base on the dead wire.

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0016] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0017] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4In equipment that uses ropes for fixing, traction, or load-bearing, rope clamps 2 are used to secure the ropes. However, displacement of rope clamps 2 can reduce the rope's securing force, leading to rope loosening or detachment. For example, displacement of rope clamps 2 in a crane's hoisting mechanism could cause serious safety accidents such as the falling of heavy objects. Simultaneously, displacement of rope clamps 2 can cause uneven stress on the rope, resulting in additional impact and wear on connected equipment components. For instance, in an elevator traction system, displacement of rope clamps 2 can accelerate the wear of the traction sheave, affecting the equipment's lifespan and safe operation.

[0018] Currently, the displacement of the rope clamp 2 mainly relies on manual periodic inspection, which is inefficient and makes it difficult to detect minute displacement changes in a timely manner. In complex working environments such as high altitude, high temperature, and humidity, manual inspection is difficult and also poses safety risks. Based on this, this application provides a rope clamp 2 displacement device, including a weighing steel wire rope 1 and a rope clamp 2 set on the steel wire rope 1, the rope clamp 2 being used to fix the steel wire rope 1; The wire rope 1 includes dead wires 11 and live wires 12. The live wires 12 and the dead wires 11 are arranged symmetrically and are fixed by rope clips 2. A sensor 3 is also provided on the outside of the dead wire 11. A mounting base 4 is provided at the bottom of the sensor 3. The mounting base 4 is located on one side of the rope clamp 2 and is used to detect the displacement of the rope clamp 2. There are two sensors 3, which are located on both sides of the rope clamp 2, and are used to detect the forward and reverse displacement of the rope clamp 2.

[0019] The wire rope 1 consists of two parts: a dead wire 11 and a live wire 12. The dead wire 11 and live wire 12 are symmetrically arranged. This symmetrical structure helps to distribute the force more evenly on the wire rope 1, improving its overall stability and load-bearing capacity. The dead wire 11 and live wire 12 are fixed together by rope clamps 2, ensuring a tight connection and coordinated function. In practical applications, the dead wire 11 is usually connected to a relatively fixed component, providing a stable support point for the entire device; while the live wire 12 will undergo certain displacement and deformation as the equipment operates to adapt to different working requirements.

[0020] A sensor 3 is installed on the outside of the dead wire 11. A mounting base 4 is provided at the bottom of the sensor 3, located on one side of the rope clamp 2. The mounting base 4 provides a stable mounting foundation for the sensor 3, ensuring that the sensor 3 can accurately detect the displacement of the rope clamp 2. The sensor 3 is tightly connected to the dead wire 11 via the mounting base 4, enabling it to sense minute displacement changes in the rope clamp 2 in real time.

[0021] The device is equipped with two sensors 3, which are installed on both sides of the rope clamp 2. This layout design is intended to comprehensively and accurately detect the forward and reverse displacement of the rope clamp 2. During equipment operation, the rope clamp 2 may experience forward or reverse displacement due to various reasons, such as equipment vibration or changes in the force on the wire rope 1. The two sensors 3, located on opposite sides, can monitor the displacement of the rope clamp 2 in different directions. When the rope clamp 2 experiences forward displacement, the sensor 3 closer to the forward side can promptly capture the displacement signal; similarly, when the rope clamp 2 experiences reverse displacement, the sensor 3 on the other side can also quickly detect the corresponding displacement change. By comprehensively analyzing the detection data from the two sensors 3, the displacement amount and direction of the rope clamp 2 can be accurately determined.

[0022] During normal operation, sensor 3 continuously monitors the displacement of rope clamp 2 and transmits the detected displacement data to the corresponding control system. The control system analyzes and judges the data based on preset displacement thresholds. If the displacement of rope clamp 2 exceeds the safe range, the control system will promptly issue an alarm signal, reminding personnel to take appropriate measures, such as adjusting or replacing rope clamp 2, to avoid safety accidents caused by rope clamp 2 displacement. Compared with existing manual detection methods, this rope clamp 2 displacement device can monitor the displacement of rope clamp 2 in real time and accurately, greatly improving detection efficiency and accuracy, reducing safety risks, and ensuring the stable operation of the equipment.

[0023] Please see Figure 4 , Figure 5 , Figure 6 as well as Figure 7 The mounting base 4 includes two support plates 41 arranged symmetrically. The two support plates 41 form a clamping area 45 for fixing the dead wire 11, thereby fixing the sensor 3.

[0024] One of the support plates 41 has a vertical detection plate 42 on one side of its top. The vertical detection plate 42 is perpendicular to one side of the support plate 41. One side of the vertical detection plate 42 is flat and is adapted to the sensor 3.

[0025] Both sides of the support plate 41 are provided with protrusions 43. The top of the protrusions 43 has two positioning holes 44, and they are adapted to another support plate 41 by fasteners to fasten the clamping area 45.

[0026] The bottom of the support plate 41 is provided with an arc-shaped groove, and the arc-shaped groove is provided with protrusions 46 arranged in a ring array, with a slot 48 formed between every two protrusions 46.

[0027] The mounting base 4 is mainly composed of two symmetrically arranged support plates 41. These two support plates 41 form a clamping area 45, which is used to firmly fix the dead wire 11 in the wire rope 1, thereby achieving reliable fixation of the sensor 3 installed on the outside of the dead wire 11. In practical applications, the dead wire 11 is placed in this clamping area 45. Through reasonable design and installation, it can be ensured that the dead wire 11 will not easily shake or shift during the operation of the device, thus providing a stable mounting base for the sensor 3 and ensuring that the sensor 3 can accurately detect the displacement of the rope clamp 2.

[0028] A vertical detection plate 42 is provided on one side of the top of one of the support plates 41. This vertical detection plate 42 is perpendicular to one side of the support plate 41, and one side of it is a flat structure that is adapted to the sensor 3. When the sensor 3 is installed on the mounting base 4, the sensor 3 can fit tightly against the flat surface of the vertical detection plate 42. This fitting method not only ensures the stability of the sensor 3 installation, but also allows the sensor 3 to better sense the displacement changes of the rope clamp 2. Because the sensor 3 is in close contact with the flat surface of the vertical detection plate 42, it can more accurately capture the minute changes caused by the displacement of the rope clamp 2, thus improving the accuracy of the detection.

[0029] Both sides of the support plate 41 are provided with protrusions 43, and each protrusion 43 has two positioning holes 44 on its top. These positioning holes 44 are used to cooperate with fasteners to connect the two support plates 41 together and secure the clamping area 45. During installation, by passing fasteners (such as bolts) through the corresponding positioning holes 44 on the two support plates 41 and then tightening them, the two support plates 41 can be made to firmly clamp the dead wire 11. This fastening method allows the tightness to be adjusted according to actual needs, ensuring that the dead wire 11 is firmly fixed within the clamping area 45, and also facilitates disassembly and reinstallation when maintenance or replacement of parts is required.

[0030] The bottom of the support plate 41 is provided with an arc-shaped groove. The shape of this arc-shaped groove matches the shape of the dead wire 11, which can better fit the surface of the dead wire 11, increase the contact area with the dead wire 11, and further improve the stability of the fixation. At the arc-shaped groove, there are protrusions 46 arranged in a circular array, with a groove 48 formed between every two protrusions 46. The design of these protrusions 46 and grooves 48 serves multiple purposes. On the one hand, they can increase the friction between the support plate 41 and the dead wire 11, preventing the dead wire 11 from sliding within the clamping area 45; on the other hand, in some special cases, such as when the surface of the dead wire 11 has some unevenness or impurities, the grooves 48 can accommodate these impurities, preventing them from affecting the tight fit between the support plate 41 and the dead wire 11, thereby ensuring the fixing effect of the mounting base 4 on the dead wire 11 and the accuracy of the sensor 3 detection.

[0031] In summary, sensor 3 can accurately and stably detect the displacement of rope clamp 2, thus providing strong support for the normal operation of the entire rope clamp 2 displacement device and the safe use of the equipment. This design plays an important role in various equipment that uses wire rope 1, such as cranes and elevators, effectively reducing the safety risks caused by the displacement of rope clamp 2.

[0032] Please see Figure 5 , Figure 6 , Figure 7 The inner side of the slot 48 is fitted with a filler, and one side of the filler that contacts the dead wire 11 is roughened to increase the friction between the clamping area 45 and the dead wire 11.

[0033] The bottom of the two protrusions 46 is provided with a locking block 47 and a docking groove 49, respectively, and the two sets of locking blocks 47 and docking grooves 49 are staggered.

[0034] In the arc-shaped groove at the bottom of the support plate 41 of the mounting base 4, a filler is installed inside the slot 48 formed between every two protrusions 46. The side that contacts the dead wire 11 is set as a rough surface. When the clamping area 45 formed by the two support plates 41 clamps the dead wire 11, the filler is in close contact with the dead wire 11. This rough surface design can significantly increase the friction between the clamping area 45 and the dead wire 11. During the operation of the equipment, the wire rope 1 will be subjected to various forces, and the dead wire 11 will also have a certain tendency to sway or displace. The rough surface of the filler can effectively prevent the dead wire 11 from sliding, ensuring that the dead wire 11 is more firmly fixed in the clamping area 45. For example, when the crane lifting mechanism is running, the wire rope 1 bears huge tension. If the dead wire 11 is not firmly fixed, it may cause the rope clamp 2 to displace and thus cause a safety accident. At this time, the increased friction of the filler can play a key stabilizing role.

[0035] The bottom of each of the two protruding strips 46 is provided with a locking block 47 and a docking groove 49, and the two sets of locking blocks 47 and docking grooves 49 are staggered. When the two support plates 41 approach each other and clamp the dead wire 11, this staggered locking block 47 and docking groove 49 can play a role in precise positioning and enhancing connection stability. During installation, the locking block 47 and docking groove 49 can guide the two support plates 41 to align accurately, ensuring the symmetry and consistency of the clamping area 45, so that the dead wire 11 is subjected to uniform force within the clamping area 45. At the same time, after the locking block 47 is embedded in the docking groove 49, it can further enhance the connection strength between the two support plates 41, preventing relative displacement between the support plates 41 due to vibration or other factors during equipment operation, thereby ensuring the fixing effect of the mounting base 4 on the dead wire 11. For example, in an elevator traction system, the equipment will generate a certain amount of vibration during operation. If the connection of the mounting base 4 is unstable, it may affect the accuracy of the displacement detection of the rope clamp 2. The design of the locking block 47 and docking groove 49 can effectively avoid this situation.

[0036] In summary, the rough surface of the filler in the slot 48 to increase friction and the misalignment of the locking block 47 and the docking groove 49 on the protrusion 46 are all designed to further improve the fixing effect of the mounting base 4 on the dead wire 11, and ensure that the rope clamp 2 displacement device can operate accurately and stably, thereby providing a more reliable guarantee for the safe operation of various equipment using ropes.

Various modifications and variations can be made to this utility model by those skilled in the art.
