Description

Technical Field

[0001] This application belongs to the field of measuring equipment technology, specifically relating to a portable handheld wire rope metering device. Background Technology

[0002] In industrial production, construction, and logistics, steel wire ropes serve as crucial load-bearing and traction components. Accurate measurement of their length is essential for project quality control, equipment safety, and material management. Currently, steel wire rope length is primarily measured manually with measuring tapes or using fixed meter counters. However, these methods have significant drawbacks: Manual tape measure measurement requires multiple people to operate, which is not only inefficient, but also difficult to implement when the wire rope is suspended, tangled or at a high altitude, resulting in large measurement errors. Fixed meter counters are usually bulky and complicated to install, and need to be fixed in specific equipment or production lines, which cannot meet the measurement needs of outdoor operations and mobile scenarios.

The spacing of the clamping space is adapted to the outer diameter of the workpiece to be measured, so as to drive the first roller and the second roller to rotate synchronously when the workpiece to be measured passes through. A detection element is disposed on the handheld part and is connected to the second roller via a transmission. The detection component detects the number of rotations and rotation angle of the second roller as the part to be measured passes through the clamping space and drives the second roller to rotate, and converts the number of rotations and rotation angle into the passing length of the part to be measured based on the circumference parameter of the second roller.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] See also Figure 1 As shown, an embodiment of this application provides a portable handheld wire rope metering device, comprising: Handheld part 1; The clamping assembly 2 includes a first roller 21 and a second roller 22, which are disposed opposite to each other on the first end of the handheld part 1. A clamping space is formed between the first roller 21 and the second roller 22 for the workpiece to be measured to pass through. The spacing of the clamping space is adapted to the outer diameter of the workpiece to be measured so as to drive the first roller 21 and the second roller 22 to rotate synchronously when the workpiece to be measured passes through. The detection element 3 is disposed on the handheld part 1 and is connected to the second roller 22 in a transmission manner; The detection component 3 detects the number of rotations and rotation angle of the second roller 22 as the part to be measured passes through the clamping space and drives the second roller 22 to rotate, and converts the number of rotations and rotation angle into the passing length of the part to be measured based on the circumference parameter of the second roller 22.

[0022] Specifically, the handheld part 1 provides the operator with a convenient grip structure, facilitating flexible operation in various scenarios. The first roller 21 and the second roller 22 in the clamping assembly 2 are positioned opposite each other at the first end of the handheld part 1, with the clamping space between them matching the outer diameter of the steel wire rope to be measured. When the steel wire rope passes through, it drives the first roller 21 and the second roller 22 to rotate synchronously. The detection element 3 is mounted on the handheld part 1 and is connected to the second roller 22 via a transmission connection, converting the rotation parameters of the second roller 22 into the length of the steel wire rope.

[0023] When the device is in operation, the operator holds the holding part 1 and passes the wire rope to be measured through the clamping space formed by the first roller 21 and the second roller 22. Since the clamping space spacing is adapted to the outer diameter of the wire rope, the wire rope will make close contact with the rollers as it moves, and the friction will drive the first roller 21 and the second roller 22 to rotate synchronously. At this time, the detection element 3, which is connected to the second roller 22, will detect the number of rotations and the rotation angle of the second roller 22. Because the circumference of the second roller 22 is a fixed parameter, the detection element 3, based on this, converts the number of rotations and the rotation angle into the length of the wire rope according to the corresponding calculation method. With the help of the holding part 1, the operator can complete the measurement alone without the need for multiple people, greatly improving the measurement efficiency. The detection element 3 allows the operator to directly obtain the length of the wire rope, avoiding errors that may occur during manual calculation.

[0024] Meanwhile, this device is suitable for a variety of complex scenarios. For suspended, tangled, or high-altitude steel wire ropes, the operator only needs to adjust the angle of the handheld part 1 to allow the steel wire rope to pass smoothly through the clamping space to complete the measurement, solving the problem that traditional manual tape measure measurements are difficult to implement in these scenarios.

[0025] The handheld part 1 is equipped with anti-slip texture to ensure that the operator can still hold it firmly when working outdoors or when hands are sweaty, so as to avoid affecting the measurement accuracy due to the device slipping.

[0026] The first roller 21 and the second roller 22 of the clamping assembly 2 are made of rubber with a high coefficient of friction, which can increase the friction between the roller and the wire rope, prevent slippage, and achieve synchronous rotation.

[0027] The clamping assembly 2 further includes: Adjustment component 4, which is disposed on the hand-held part 1 and connected to the first roller 21, is used to adjust the distance of the clamping space.

[0028] Specifically, the clamping assembly 2 also includes an adjusting component 4, which is disposed on the hand-held part 1 and connected to the first roller 21. It is used to adjust the distance of the clamping space between the first roller 21 and the second roller 22, so as to adapt to more steel wire ropes with different outer diameters and greatly improve the versatility of the equipment.

[0029] The adjusting element 4 can be a knob-type screw or a sliding buckle. When the operator needs to measure wire ropes of different diameters, they only need to rotate the knob or push the slider to drive the adjusting element 4, which will move the first roller 21 closer to or further away from the second roller 22, thereby changing the spacing of the clamping space. For example, when measuring thicker wire ropes, the clamping space is increased by adjusting the adjusting element 4; when measuring thinner wire ropes, the spacing is reduced, ensuring that the wire rope can maintain close contact with the two rollers regardless of the diameter, ensuring that the friction is sufficient to drive the rollers to rotate synchronously, and avoiding slippage that affects measurement accuracy. The setting of the adjusting element 4 allows the first roller 21 and the second roller 22 to adapt to various measurement needs, eliminating the need for a dedicated meter measuring device for wire ropes of different diameters, reducing equipment procurement costs and carrying burden.

[0030] The adjusting component 4 is a bolt.

[0031] The first roller 21 has a V-shaped structure, and the second roller 22 has a cylindrical structure.

[0032] Specifically, the V-shaped structure of the first roller 21 consists of two symmetrically inclined wheel surfaces, forming an angled groove. When the wire rope passes through the clamping space, regardless of its diameter, the two wheel surfaces of the V-shaped groove can form line contact with the surface of the wire rope. After adjusting the spacing by the adjusting piece 4, the wire rope can be stably confined at the bottom of the groove, preventing lateral displacement of the wire rope during measurement. Compared with the traditional arc-shaped groove, the contact area of ​​the V-shaped structure changes more reasonably with the diameter of the wire rope, providing sufficient clamping force for thin wire ropes without increasing rotational resistance due to excessive compression of thick wire ropes.

[0033] The second roller 22 adopts a cylindrical structure. When the wire rope is positioned by the V-shaped structure, the cylindrical second roller 22 can form a stable linear contact from the other side, ensuring that the wire rope drives the first roller 21 and the second roller 22 to rotate synchronously when moving. At the same time, since the circumference of the second roller 22 is fixed, the detection element 3 can measure the length of the wire rope by the number of rotations and angle of the second roller 22.

[0034] The detection component 3 includes an encoder and a data processing unit. The encoder is connected to the second roller 22 in a transmission manner. The data processing unit converts the detected rotation amount into the passing length of the component to be measured according to the preset circumference parameter of the second roller 22.

[0035] Specifically, the encoder is connected to the second roller 22 via a transmission mechanism, which can transmit the rotation of the second roller 22 synchronously to the encoder through gear meshing, belt drive, or direct coaxial connection. When the second roller 22 rotates with the steel wire rope, the encoder can capture its rotation number and rotation angle within each rotation in real time, converting the mechanical motion into pulse signals or digital quantities.

[0036] The data processing unit pre-stores the circumference parameter of the second roller 22. Upon receiving rotation data from the encoder, the unit calculates the circumference using the formula: "Length = Number of rotations × Roller circumference + Arc length corresponding to the rotation angle". For example, if the circumference of the second roller 22 is 200mm, and the encoder detects two rotations plus an additional 90°, the data processing unit automatically calculates 2 × 200 + (90° / 360°) × 200 = 450mm. Compared to traditional mechanical counting methods, this is more accurate, has smaller measurement errors, and meets the measurement needs of different scenarios.

[0037] A display screen 5 is provided on the first end of the handheld part 1.

[0038] Specifically, a display screen 5 is provided on the first end of the handheld part 1. The display screen 5 is connected to the data processing unit of the detection component 3 and can receive and display the length of the steel wire rope to be measured calculated by the data processing unit in real time, providing the operator with intuitive and immediate measurement results.

[0039] The display screen 5 is located at the first end of the handheld part 1 and close to the clamping component 2. When the operator holds the handheld part 1 to make measurements, he / she can clearly observe the screen content without changing the hand posture, thus avoiding operation deviation or measurement interruption caused by the shift of the line of sight.

[0040] The handheld part 1 is provided with a communication unit 6.

[0041] Specifically, the handheld part 1 is equipped with a communication unit 6, which is connected to the data processing unit of the detection component 3. The communication unit 6 can transmit or store the measurement data calculated by the data processing unit in real time, which provides convenience for the subsequent management, analysis and sharing of measurement data.

[0042] Communication unit 6 can use wireless communication methods such as Bluetooth, Wi-Fi, or NFC, or it can be equipped with a wired communication interface such as a USB interface to adapt to data transmission needs in different scenarios. After the device completes the measurement of the wire rope length, the data processing unit will synchronously send the measurement results to communication unit 6. Operators can quickly export the data by connecting to devices such as mobile phones and computers.

[0043] A storage battery 7 is provided on the second end of the handheld part 1.

[0044] A switch 8 is provided on the handheld part 1.

[0045] Specifically, a battery 7 is installed at the second end of the handheld unit 1, and a switch 8 is also provided on the handheld unit 1 to provide power and ensure stable and convenient operation of the device in mobile scenarios. The battery 7 is installed at the bottom of the second end of the handheld unit 1 and is a rechargeable battery, which can provide continuous power to power-consuming components such as the detection element 3, the display screen 5, and the communication unit 6. When the battery is low, the operator can replenish the battery 7 using a dedicated charger. The charging interface is usually designed on the side of the handheld unit 1 for easy connection to a power source.

[0046] The switch 8 is located in the grip area of ​​the handheld part 1 for easy and quick start and stop of the device. The switch 8 not only controls the overall power supply of the device, but also puts the device into standby mode when the switch 8 is off, which can significantly reduce the power consumption of the battery 7 and extend the battery life.

[0047] The detection component 3, the display screen 5, the communication unit 6, the storage battery 7, and the switch 8 are electrically connected.

[0048] Specifically, the detection component 3, display screen 5, communication unit 6, battery 7, and switch 8 are electrically connected. Battery 7 provides power to detection component 3, display screen 5, and communication unit 6 through the electrical connection, while switch 8 is connected in series in the circuit and controls the power supply to the entire device through the electrical connection: when switch 8 is open, the current from battery 7 is delivered to each component through the circuit, and the device enters the working state; when switch 8 is closed, the circuit is disconnected, and each component stops receiving power, effectively avoiding power waste.

[0049] The detection element 3 and the display screen 5 are electrically connected to achieve data communication. The wire rope length data calculated by the detection element 3 can be transmitted to the display screen 5 in real time and displayed. The electrical connection between the detection element 3 and the communication unit 6 allows the measurement data to be transmitted to the outside through the communication unit 6.
