Description

Technical Field

[0001] This utility model relates to the field of weighing device technology, and in particular to a multi-weighing-point collaborative weighing device for long objects. Background Technology

[0002] In industrial production, there is a widespread need to weigh long objects (such as metal rods, copper tubes, etc.), and the accuracy of their weight measurement directly affects production quality control, cost accounting, and logistics transportation planning.

[0003] In existing technologies, weighing long objects often employs single-point support or a few dispersed support points. Due to the significant weight and length of long objects, single-point or few-point support can easily cause bending and deformation due to their own weight, resulting in uneven weight distribution and consequently low weighing accuracy. Furthermore, traditional weighing devices are often installed using welding or drilling, which can damage the frame structure, affecting frame strength and making disassembly and maintenance difficult, hindering their ability to adapt to the flexible adjustment requirements of production lines. In addition, existing devices lack a synchronous control mechanism for each support point, which can easily generate additional stress due to differences in the timing of support point actions, further reducing weighing accuracy. Moreover, the lack of intuitive process status indicators makes it difficult for operators to monitor the weighing process and abnormal situations in real time, increasing manual monitoring costs and operational risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a multi-weighing point collaborative weighing device for long objects, which features multi-point collaborative weighing, high weighing accuracy, and status monitoring capabilities.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] A multi-weighing-point collaborative long object weighing device includes a frame and a plurality of weighing-point units disposed on the frame, the weighing-point units being spaced apart along the length of the frame; the weighing-point units are detachably mounted on the frame by a fixing component.

[0007] Each of the weighing point units includes a booster cylinder, a sensor assembly, and a fixing clamp;

[0008] The sensor assembly is disposed at the output end of the booster cylinder;

[0009] The retaining clip is disposed on the top of the sensor assembly;

[0010] The booster cylinders of multiple weighing point units rise and fall synchronously, driving the sensor assembly and fixing clamp to form a cooperative load-bearing plane.

[0011] Through the above technical solution, multiple weighing point units distributed at intervals along the length of the frame, together with the fixing components, allow the device to be detachably installed on the frame, realizing a modular layout for multi-point collaborative weighing of long objects; the booster cylinder drives the sensor components and fixing clamps to form a collaborative load-bearing plane, so that the weight of the long object is distributed to each weighing point, improving the weighing accuracy and stability, while the detachable design facilitates the installation and maintenance of the device.

[0012] As a further technical solution of this utility model: the fixing component includes a support plate and two clamping plates disposed on both sides above it, the support plate and the clamping plates being detachably fixed to the lower edge of the channel steel of the frame;

[0013] The lower surfaces of the two clamping plates are attached to the upper surface of the lower edge of the channel steel;

[0014] The upper surface of the support plate is attached to the lower surface of the lower edge of the channel steel;

[0015] The clamping plate and the support plate are vertically inserted sequentially by bolts and locked in place by nuts.

[0016] Through the above technical solution, the two clamping plates and the support plate are bolted vertically through the lower edge of the channel steel and locked together to form a stable connection of upper and lower clamping. This not only ensures the reliable fixation of the device and the frame, but also avoids damage to the channel steel body. At the same time, it achieves non-destructive installation and disperses the clamping force through surface contact to prevent local deformation from affecting the weighing accuracy.

[0017] As a further technical solution of this utility model: each weighing point unit is provided with three guide columns. The top of the guide column is fixedly connected to the mounting plate of the sensor assembly. The bottom of the guide column is slidably embedded in the guide sleeve. The guide sleeve is fixed to the support plate. The three guide columns are distributed in a triangle along the bottom surface of the mounting plate to constrain the mounting plate to move only in the vertical direction.

[0018] Through the above technical solution, three guide columns are distributed in a triangle on the bottom surface of the mounting plate. Their tops are fixed to the sensor assembly mounting plate and their bottoms are slidably embedded in the support plate guide sleeve, forming a stable spatial constraint. This effectively limits the horizontal displacement and rotation of the mounting plate, ensuring that the sensor assembly moves only in the vertical direction, which greatly improves the anti-interference ability and measurement stability during the weighing process.

[0019] As a further technical solution of this utility model, it also includes a control unit, which is electrically connected to the booster cylinder of each weighing point unit and is used to control all the booster cylinders to lift synchronously; the control unit is electrically connected to the sensor assembly of each weighing point unit and is used to receive the weight data of each sensor assembly, process the data and calculate the total weight of the long object.

[0020] Through the above technical solution, the control unit synchronously controls the lifting and lowering of all booster cylinders to ensure that each weighing point operates synchronously, eliminating measurement errors caused by differences in the timing of actions; at the same time, it collects and processes data from each sensor and calculates the total weight, realizing automatic and accurate measurement of the weight of long objects. Combined with closed-loop control logic, the weighing process can be further optimized.

[0021] As a further technical solution of this utility model, it also includes an alarm light, which is electrically connected to the control unit and is used to indicate the weighing process status.

[0022] Through the above technical solution, the alarm light indicates the weighing process status in real time through different colors or flashing patterns, such as ready, weighing in progress, abnormal, etc., so that operators can intuitively monitor the system operation. When abnormalities such as excessive weight deviation or sensor failure occur, an alarm is triggered in time, which improves the safety and operability of the equipment and reduces the cost of manual monitoring.

[0023] In summary, this utility model has at least one of the following beneficial technical effects:

[0024] 1. This utility model discloses a multi-weighing point collaborative long object weighing device, which uses multiple weighing point units distributed at intervals along the length of the frame, and the booster cylinders of each unit drive the sensor assembly and fixing clamp to form a collaborative load-bearing plane, thereby realizing the decentralized and accurate weighing of long objects and modular rapid deployment.

[0025] 2. This utility model discloses a multi-weighing-point collaborative long object weighing device, which achieves anti-interference stability (suppressing horizontal deviation and synchronization error) and accurate data acquisition and calculation in the weighing process through the non-destructive locking structure of the lateral clamping plate and the support plate, the vertical movement constraint of the triangular guide column, and the centralized control of the cylinder synchronous lifting and weight data by the control unit.

[0026] 3. This utility model discloses a multi-weighing point collaborative long object weighing device, which uses alarm lights to visually indicate the process status, realizes real-time perception of faults and status, and improves the convenience of intelligent operation and maintenance.

[0034] Example 1:

[0035] Reference Figure 1 , Figure 2 and Figure 3This utility model discloses a multi-weighing-point collaborative long object weighing device, including a frame 1 and multiple weighing point units 2 disposed on the frame 1. The weighing point units 2 are spaced apart along the length of the frame 1 and are detachably mounted on the frame 1 by a fixing component 21. In this embodiment, the fixing component 21 consists of a support plate 211 and two clamping plates 212 on both sides thereof. The three components are detachably fixed to the lower edge of the channel steel 3 of the frame 1 by bolts 4 and nuts 5. Specifically, the lower surfaces of the two clamping plates 212 are attached to the upper surface of the lower edge of the channel steel 3, the upper surface of the support plate 211 is attached to the lower surface of the lower edge of the channel steel 3, and the bolts 4 penetrate vertically through the clamping plates 212 and the support plate 211 and are locked by nuts 5. This structure avoids damage to the channel steel 3 body and disperses the clamping force through surface contact, ensuring the long-term stability of the weighing reference. Furthermore, in practical applications, the installation position and fixing method of each weighing point unit 2 can be flexibly configured according to the actual scenario. In the material conveying frame scenario, the fixing component 21 can be detachably installed by clamping the lower edge of the channel steel 3. When facing other industrial frames such as I-beams and rectangular tube supports, the fixing component 21 can be fixed by replacing the adapter module and using various fixing methods such as welding, bolt connection, guide rail slider or magnetic adsorption (e.g., welding to the frame surface, connecting through flange bolts, quick sliding positioning along the guide rail or using electromagnetic chuck to achieve ready-to-use). The installation position can be distributed as needed on different load-bearing parts such as the upper flange, web or side of the frame 1.

[0036] Each weighing point unit 2 includes a booster cylinder 22, a sensor assembly 23, and a fixing clamp 24, achieving distributed weighing of long objects through modular design. The fixing clamp 24 adopts a semi-enclosed limiting structure, consisting of a support horizontal plate and longitudinal baffles on both sides, which restricts the long object from sliding along the weighing direction, ensuring that the weight is vertically transmitted to the sensor assembly 23 and avoiding displacement errors.

[0037] The booster cylinder 22 is fixed to the upper surface of the support plate 211, and the top end of its piston rod (output end) is directly connected to the mounting plate 231 of the sensor assembly 23 (fixed by bolts or welded). When the booster cylinder 22 works, the extension and retraction of the piston rod drives the mounting plate 231 through the output end, which drives the sensor assembly 23 and the top fixing clamp 24 to rise and fall synchronously, so as to realize the "lifting and weighing" or "releasing and resetting" of long objects.

[0038] Each weighing point unit 2 is also equipped with three guide posts 6, the top of which is fixedly connected to the mounting plate 231, and the bottom is slidably embedded in the guide sleeve 61 on the support plate 211. The three guide posts 6 are distributed in a triangle along the bottom surface of the mounting plate 231, which can limit the horizontal displacement and rotation of the mounting plate 231, ensuring that the sensor assembly 23 is only subjected to vertical load, thus eliminating the influence of lateral interference on weight measurement from a structural perspective.

[0039] The device also integrates a control unit and an alarm light. The control unit synchronously controls the booster cylinders 22 of all weighing point units 2 via electrical connection to eliminate differences in action timing. At the same time, it collects the weight data of each sensor component 23 in real time and calculates the total weight of the long object through an algorithm. The alarm light is linked with the control unit and uses a "color + flashing mode" to intuitively indicate the process status such as equipment readiness, weighing in progress, and abnormal alarm, thereby improving operation and maintenance efficiency and operational safety.

[0040] Reference Figure 3 The number of weighing point units 2 can be dynamically configured according to the actual length of the long object to be weighed. For example, 20 units are used in this embodiment. In actual applications, the number can be increased or decreased based on the span requirements. The spacing between adjacent weighing point units 2 should ensure uniform support and deformation control throughout the entire length range. The spacing between adjacent weighing point units 2 is usually 1.5m. The actual spacing can be adjusted according to the specific working conditions. For example, for a 28m long object, 20 weighing point units 2 are used, and a non-uniform spacing design is adopted to adapt to its mechanical properties. Specifically, the spacing design adopts "initial densification → middle uniformity → end contraction", as follows: the initial section is densified with support, for example, the distance between the first weighing point unit 2 and the second weighing point unit 2 is about 0.8m, which offsets the additional bending moment at the front end of the long object during lifting / transportation and suppresses the bending deformation of the initial section; the middle section is uniformly covered, for example, the distance between the second weighing point unit 2 to the eighteenth weighing point unit 2 is 1.5m, so that the weight of the long object is linearly distributed to each weighing point unit 2, avoiding local stress concentration; the end section is gradually contracted to adapt to the boundary of the frame 1 and constrain the end deformation. For example, the distance between the eighteenth weighing point unit 2 and the nineteenth weighing point unit 2 is 1.35m, and the distance between the nineteenth weighing point unit 2 and the twentieth weighing point unit 2 is 0.95m, which adapts to the end installation boundary of the frame 1 and constrains the drooping deformation of the end of the long object through densified support. The layout consists of 20 units with a total span of approximately 27m, ensuring that the suspended section between all adjacent support points of long objects is ≤1.5m. It can accommodate objects up to 30m long (with a maximum suspended section of 1.5m / end), providing a mechanical basis for the stable construction of the collaborative load-bearing plane.

[0041] Under the synchronous drive of the booster cylinder 22, the sensor components 23 of each weighing point unit 2 and the fixing clamp 24 together form a cooperative load-bearing plane, distributing the weight of the long object to 20 weighing point units 2; combined with the triangular constraint of the guide column 6, the horizontal displacement of the mounting plate 231 is limited to ensure the vertical transmission of the load, and the control unit accurately controls the synchronization of the booster cylinder 22 (eliminating action timing errors) and collects and calculates weight data in real time. Finally, from the three dimensions of force distribution, directional constraint and closed-loop control, high-precision and stable weighing of long objects is achieved.

[0042] The working process of this utility model is as follows: Multi-weighing-point coordinated long object weighing device

[0043] Step 1: System initialization. Each weighing point unit 2 is fixed to the lower edge of the channel steel 3 of the frame 1 by fixing component 21. The control unit completes self-test and initializes parameters, and enters the standby state.

[0044] Step 2: Automatic mode is triggered. Click the "Start" button in the automatic control area. The system switches to automatic operation and waits for the sensor component 23 to detect the arrival signal of the long object (cast billet).

[0045] Step 3: Long object positioning detection. After the long object touches the sensor assembly 23, the alarm light turns red (indicating "object has arrived"). The control board sends an arrival signal to the control unit, and the system starts a positioning wait for a set time (to ensure the long object is stable).

[0046] Step 4: Weighing preparation. After the positioning and waiting period is over, the alarm light turns yellow (indicating "ready"). The control unit sends a zeroing command to each sensor assembly 23 to eliminate initial load interference.

[0047] Step 5: Coordinated load-bearing start-up. The control unit controls all the booster cylinders 22 to move upward synchronously, driving the sensor assembly 23 and the fixing clamp 24 to rise and contact the long object. At this time, the guide column 6 slides vertically along the guide sleeve 61 with the mounting plate 231 of the sensor assembly 23 to ensure smooth movement without deviation.

[0048] Step Six: Weight Data Acquisition. After the long object and the load-bearing system have stabilized, the control unit synchronously acquires the weight data of each sensor component 23 to complete a single data recording.

[0049] Step 7: System reset. After data acquisition is completed, the control unit controls the booster cylinder 22 to move down synchronously, the guide column 6 resets with the mounting plate 231, and the green alarm light illuminates (indicating "weighing completed").

[0050] Step 8: Data processing and storage. In single-loop mode, the data from this step is used as the final result. In double-loop mode, steps 3 to 7 are repeated for a second weighing. The average of the two weighings is taken as the final weight. The data is synchronously stored in the local and remote MES databases.

[0051] Step Nine: Manual mode operation. In manual mode, clicking the "Manual Single" button will directly trigger the weighing cycle from Step Three to Step Eight, which is equivalent to triggering the sensor component 23 and is suitable for scenarios requiring manual intervention.

[0052] Throughout the weighing process, alarm lights provide real-time indication of the process status, such as ready, weighing in progress, and abnormality, facilitating monitoring by operators.

[0053] The implementation principle of this utility model is as follows: The device uses 20 weighing point units 2 distributed at intervals along the frame 1 to disperse the weight of long objects and suppress bending due to their own weight; the fixing component 21 clamps the channel steel 3 with clamping plates 212 and support plates 211, and locks it with bolts 4 to achieve non-destructive and stable installation, ensuring the stability of the weighing benchmark; the control unit synchronously regulates the lifting and lowering of the booster cylinder 22 to eliminate stress interference caused by differences in the timing of actions; three guide columns 6 are distributed in a triangle to constrain the mounting plate 231 of the sensor component 23, limiting its horizontal displacement and rotation, ensuring that the weight is collected in the vertical direction; the control unit receives data from each sensor component 23 and calculates the total weight, and the alarm light indicates the weighing process nodes and abnormalities according to the control unit's instructions. The coordinated structure achieves high precision and stability in weighing long objects, solving the problems of single-point force deformation, complex installation, and insufficient accuracy of traditional devices.

[0054] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
