Abstract
Description
Technical Field
[0001] This utility model relates to the field of weighing and counting technology, specifically a bolt weighing and counting mechanism. Background Technology
[0002] In shield tunnel construction, bolts are critical components for connecting segments during segment assembly, and their quantity is large and management complex. Traditional bolt management methods often involve dividing the area next to the construction walkway and stacking bolts there. However, collisions and squeezing can easily occur during handling and stacking, damaging the bolt threads. At the same time, bolt count management during segment assembly relies on manual counting, which is not only inefficient but also prone to counting errors, thus affecting construction procedures. Therefore, there is an urgent need for an integrated mechanism that combines protective functions with automatic weighing and counting capabilities. However, existing technologies lack a solution that can balance structural compactness and measurement accuracy, including the metrological characteristics of weighing sensors, measurement range definition, error control, and calibration test methods.
[0003] Therefore, it is necessary to propose a bolt weighing and counting mechanism to solve or at least alleviate the above-mentioned defects. Utility Model Content
[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.
[0005] This utility model provides a bolt weighing and counting mechanism, comprising: a bolt storage box, a limiting component, and a weighing and counting component. The bolt storage box is disposed above the weighing and counting component, and the limiting component is disposed on the bolt storage box. The limiting component is used to limit the position and orientation of the bolts, and the weighing and counting component is used to calculate the weight and quantity of the bolts.
[0006] The bolt weighing and counting mechanism provided by this utility model has at least the following beneficial effects: By using a limiting component installed on the bolt storage box, compared to the traditional method of randomly piling bolts along construction walkways, it greatly reduces collisions and compression of bolts during handling and stacking, effectively protecting bolt threads, reducing the risk of damage, extending bolt service life, ensuring their quality, and laying a solid foundation for the stability of shield tunnel segment connections. On the other hand, the weighing and counting component brings about an innovation in counting methods. It can automatically and accurately calculate the weight and quantity of bolts, abandoning the inefficient manual counting mode of the past, avoiding counting errors caused by human negligence, enabling the smooth progress of construction procedures, reducing construction delays caused by bolt quantity issues, comprehensively improving the overall efficiency and quality of shield tunnel construction, and providing an efficient and reliable solution for bolt management during construction.
[0007] Furthermore, the weighing and counting assembly includes a pressure sensor, a control unit, and a load-bearing housing. The pressure sensor is located inside the load-bearing housing and is used to sense and measure the weight of the bolts. The control unit is located inside the load-bearing housing and is electrically connected to the pressure sensor. The load-bearing housing is located below the bolt storage box. The control unit is used to receive the weight data of the bolts and calculate the number of bolts based on the weight data. By installing a pressure sensor inside the load-bearing housing, the weight of the bolts can be sensitively and accurately sensed and measured, providing an accurate data foundation for subsequent counting work. This effectively avoids counting errors caused by inaccurate weight measurement and greatly improves the reliability of counting. Secondly, the electrical connection between the control unit and the pressure sensor, along with its rapid data processing capabilities, allows the bolt weight data to be quickly received and accurately calculated based on preset parameters and algorithms, thereby quickly obtaining the number of bolts. This greatly improves work efficiency and saves manpower and material costs, making it particularly suitable for rapid counting of large-scale bolts. Furthermore, the entire weighing and counting assembly has a compact structure, is easy to install and maintain, and has good stability and durability. It can operate stably in various complex working environments, providing an efficient and reliable bolt counting solution for related production, warehousing, and other processes, with broad application prospects and practical value.
[0008] Furthermore, the limiting component includes a first limiting plate and a second limiting plate. The first limiting plate is disposed above the bolt storage box, and the second limiting plate is disposed at the bottom of the bolt storage box. The first limiting plate and the second limiting plate are used to limit the position and orientation of the bolt. The first limiting plate located above the bolt storage box and the second limiting plate located at the bottom work together to precisely restrict the position and posture of the bolts. During bolt storage and retrieval, this effectively prevents bolts from colliding and squeezing against each other, and effectively prevents bolts from sliding or rolling, which could damage or deform the threads and bolts. This not only reduces the risk of bolt thread damage, ensuring bolt quality and extending their service life, but also keeps the bolts arranged in an orderly manner, facilitating quick retrieval by construction personnel and improving construction efficiency. The stable bolt placement also provides favorable conditions for the accurate operation of the weighing and counting components. At the same time, the bolt storage box is tightly installed without gaps with the first and second limiting plates, protecting the bolts by keeping them inside the storage box and preventing them from being exposed to the outside for a long time. This effectively prevents dust, impurities, and other foreign objects from adhering to the bolt surface, thus avoiding rust and corrosion caused by the accumulation of foreign objects, ensuring the mechanical properties and service life of the bolts. Moreover, it can resist damage to the bolts caused by accidental external collisions, ensuring their dimensional accuracy and structural integrity.
[0009] Furthermore, the weighing and counting component also includes an electronic display screen, which is located on the outer surface of the load-bearing housing and electrically connected to the control unit. The electronic display screen is used to display the weight and quantity information of the bolts. By adding an electronic display screen to the outer surface of the load-bearing housing, the convenience of bolt management is greatly improved. It can intuitively display the weight and quantity information of the bolts, and construction personnel can obtain key data at a glance without additional operation. This not only improves work efficiency but also makes bolt management more transparent, facilitating timely monitoring of inventory status and providing strong support for the smooth progress of shield tunnel construction.
[0010] Furthermore, a battery compartment is provided at the bottom of the load-bearing housing to store the battery that provides power to the weighing and counting components. In the bolt weighing and counting mechanism, placing the battery compartment at the bottom of the load-bearing housing to store the battery that provides power to the weighing and counting components ensures stable operation of the components, guarantees accurate weighing and counting data, and at the same time, the bottom layout saves space, making the overall mechanism compact and facilitating battery maintenance and replacement, thus improving the efficiency and reliability of the mechanism.
[0011] Furthermore, a gasket is provided at the bottom of the load-bearing housing to provide cushioning and support for the weighing and counting assembly. In terms of cushioning, when the bolt weighing and counting mechanism is subjected to external vibration, collision, or impact force caused by improper operation, the gasket can effectively absorb and disperse energy, reducing the impact on the weighing and counting assembly, and mitigating problems such as component loosening and poor contact caused by vibration. This extends the service life of the weighing and counting assembly and ensures its long-term stable operation.
[0012] Furthermore, the first limiting plate has a first through-hole array, and the second limiting plate has a second through-hole array. The first through-hole array is located directly above the second through-hole array. The first through-hole array is used to limit the storage position and posture of the bolt head, and the second through-hole array is used to limit the storage position and posture of the bolt tail. The diameter of the first through-hole array is slightly smaller than that of the bolt head, which can firmly hold the bolt head and ensure that the bolt is in the predetermined position during storage, preventing it from shaking or shifting randomly. A washer is placed above the bolt to protect the bolt head. The diameter of the second through-hole array is slightly larger than that of the bolt thread outer diameter to protect the bolt thread and prevent it from colliding with the second limiting plate during bolt storage and retrieval, which would cause thread wear. Because the first through-hole array precisely limits the bolt head, and the second through-hole array firmly limits the bolt tail, the two are aligned vertically, ensuring that the bolt is always neatly and orderly arranged in the bolt storage box, which is conducive to the efficient use of the bolt storage box space.
[0013] Furthermore, all the first through holes in the first through hole array are circular in shape, and all the second through holes in the second through hole array are circular in shape. Designing the first and second through holes as circular allows for excellent adaptation to the shapes of the bolt head and tail. The circular through holes provide a stable accommodating space for the bolt, ensuring that the bolt head and tail fit tightly within the hole. This guarantees that the bolt remains in a precise position during storage and retrieval, ensuring consistency in bolt position and orientation. This contributes to improving the stability and reliability of the entire bolt storage system, preventing bolts from swaying or shifting within the box. The circular design also avoids additional friction and collisions caused by shape mismatch during storage, reducing wear on the bolt surface and threads, thus extending the bolt's service life and ensuring that its performance and connection strength are not affected during shield tunnel construction.
[0014] Furthermore, the diameter of the first through hole is larger than that of the second through hole. This design allows for better adaptation to the structural characteristics of the bolt. Typically, the bolt head is larger than the tail. By setting the first through hole to a larger diameter and the second through hole to a smaller diameter, the bolt can be placed in the limiting assembly in the correct orientation. Since the bolts can be stored with the head on top and the tail on the bottom, closely fitting the corresponding through hole, the space of the bolt storage box can be utilized more fully. The different hole diameters also make the bolts more neatly and orderly arranged during storage, thereby improving the space utilization rate of the bolt storage box. This allows more bolts to be stored in the same space, which helps to improve the space management efficiency of the construction site.
[0015] Furthermore, the bolt weighing and counting mechanism also includes a signal interface, which is located inside the load-bearing housing. The electronic display screen and the control unit are connected through the signal interface. The signal interface has good contact performance and anti-interference capability, ensuring stable signal transmission from the control unit to the electronic display screen, thereby ensuring real-time information updates and display.
[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation
[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0024] like Figure 1-4 As shown, a bolt weighing and counting mechanism includes: a bolt storage box 1, a limiting component 2, and a weighing and counting component 3. The bolt storage box 1 is located above the weighing and counting component 3, and the limiting component 2 is located on the bolt storage box 1. The limiting component 2 is used to restrict the position and posture of the bolts. By setting the limiting component 2, the position and posture of the bolts can be effectively restricted. Compared with the traditional random stacking of bolts along construction walkways, this greatly reduces the collision and squeezing of bolts during handling and stacking, thereby reducing the risk of damage to the bolt threads and extending the service life of the bolts. The lifespan of the bolts ensures their quality and provides a guarantee for the stability of the segment connections during shield tunnel construction. The weighing and counting component 3 is used to calculate the weight and quantity of the bolts. The weighing and counting component 3 can automatically calculate the weight and quantity of the bolts, which completely changes the previous method of relying on manual counting during segment assembly. This avoids the problem of low efficiency of manual counting and effectively prevents counting errors caused by human negligence. It ensures that the construction process can proceed smoothly, reduces construction delays or other problems caused by inaccurate bolt counts, and improves the overall efficiency and quality of shield tunnel construction.
[0025] By using the limiting component 2 installed on the bolt storage box 1, compared with the traditional method of randomly stacking bolts beside the construction walkway, the collision and compression of bolts during handling and stacking are greatly reduced. This effectively protects the bolt threads, reduces the risk of damage, extends the service life of the bolts, and ensures their quality, laying a solid foundation for the stability of the shield tunnel segment connection. On the other hand, the weighing and counting component 3 brings about an innovation in the counting method. It can automatically and accurately calculate the weight and quantity of bolts, abandoning the inefficient mode of manual counting in the past, avoiding counting errors caused by human negligence, enabling the construction process to proceed smoothly, reducing construction delays caused by bolt quantity issues, and comprehensively improving the overall efficiency and quality of shield tunnel construction. This provides an efficient and reliable solution for bolt management during the construction process.
[0026] The weighing and counting assembly 3 includes a pressure sensor 31, a control unit 32, and a load-bearing housing 33. The pressure sensor 31 is located inside the load-bearing housing 33 and is used to sense and measure the weight of the bolts. The pressure sensor 31, installed inside the load-bearing housing 33, can sensitively sense and accurately measure the weight of the bolts and transmit the weight data to the control unit 32 for processing, providing an accurate data basis for subsequent counting. The control unit 32 is located inside the load-bearing housing 33 and is electrically connected to the pressure sensor 31. The load-bearing housing 33 is located below the bolt storage box 1. The control unit 32 is used to receive the weight data of the bolts and calculate the number of bolts based on the weight data. The control unit 32 can be a single-chip microcomputer of the STC89C51 series. The control unit 32, using STM32 series microcontrollers, MSP430 series microcontrollers, microprocessors, programmable logic controllers, etc., can quickly receive bolt weight data from the pressure sensor 31. Based on the weight data and preset bolt weight parameters and algorithms, it calculates the number of bolts. The bolt count calculation steps include: S1: reading the weight parameters of a single bolt from memory; S2: calculating the bolt count based on the weight data and weight parameters using a weighted average algorithm. The control unit 32 is fixedly connected to the inner wall of the load-bearing housing 33 with fastening bolts, ensuring that the control unit 32 will not loosen or fall off under vibration or impact. The signal from the pressure sensor 31 is connected to the control unit 32 via a dedicated wire. This dedicated wire has excellent electromagnetic shielding performance, effectively resisting complex external electromagnetic interference. This greatly reduces signal fluctuations and distortions caused by external interference, ensuring that the signal collected by the pressure sensor 31 can be transmitted stably and accurately to the control unit 32, thereby reducing external interference and ensuring signal stability and accuracy.
[0027] By installing a pressure sensor 31 inside the load-bearing housing 33, the weight of the bolts can be sensitively and accurately sensed and measured, providing an accurate data foundation for subsequent counting work. This effectively avoids counting errors caused by inaccurate weight measurement and greatly improves the reliability of counting. Secondly, the electrical connection between the control unit 32 and the pressure sensor 31, along with its rapid data processing capabilities, allows the bolt weight data to be quickly received and accurately calculated based on preset parameters and algorithms, thereby quickly obtaining the number of bolts. This greatly improves work efficiency and saves manpower and material costs, making it particularly suitable for rapid counting of large-scale bolts. Furthermore, the entire weighing and counting assembly 3 has a compact structure, is easy to install and maintain, and has good stability and durability. It can operate stably in various complex working environments, providing an efficient and reliable bolt counting solution for related production, warehousing, and other processes, with broad application prospects and practical value.
[0028] The limiting component 2 includes a first limiting plate 21 and a second limiting plate 22. The first limiting plate 21 is located above the bolt storage box 1, and the second limiting plate 22 is located at the bottom of the bolt storage box 1. The first limiting plate 21 and the second limiting plate 22 are used to limit the position and posture of the bolt.
[0029] The first limiting plate 21 located above the bolt storage box 1 and the second limiting plate 22 located at the bottom work together to precisely restrict the position and posture of the bolts. During the storage and retrieval of bolts, this effectively avoids collisions and squeezing between bolts, and effectively prevents bolts from sliding or rolling, which could cause damage or deformation to the threads and bolts. This not only reduces the risk of bolt thread damage, ensuring bolt quality and extending their service life, but also makes the bolts arranged in an orderly manner, facilitating quick retrieval by construction personnel and improving construction efficiency. The stable bolt placement also provides favorable conditions for the accurate operation of the weighing and counting components 3. At the same time, the bolt storage box 1 is tightly installed with the first limiting plate 21 and the second limiting plate 22 without gaps, so that the bolts are protected inside the bolt storage box 1, preventing them from being exposed to the outside for a long time. This effectively prevents dust, impurities and other foreign objects from adhering to the bolt surface, thereby avoiding bolt rusting and corrosion caused by the accumulation of foreign objects, ensuring the mechanical properties and service life of the bolts. Moreover, it can resist damage to the bolts caused by accidental external collisions, ensuring their dimensional accuracy and structural integrity.
[0030] The weighing and counting component 3 also includes an electronic display screen 34, which is located on the outer surface of the load-bearing housing 33. The electronic display screen 34 is electrically connected to the control unit 32. The electronic display screen 34 is used to display the weight and quantity information of the bolts. By adding the electronic display screen 34 to the outer surface of the load-bearing housing 33, the convenience of bolt management is greatly improved. It can intuitively display the weight and quantity information of the bolts. Construction personnel do not need to perform any additional operations and can obtain key data at a glance. This not only improves work efficiency but also makes bolt management more transparent, making it easier to grasp the inventory status in a timely manner and providing strong support for the smooth progress of shield tunnel construction.
[0031] The control unit 32 has an internal memory for storing the weighing and counting results. The internal memory of the control unit 32 can save the data in real time, avoid data loss due to unexpected power outages or equipment failures, and facilitate staff to access historical data at any time. This provides a basis for inventory management, usage frequency analysis, etc., helps to optimize the bolt storage and retrieval process, and improves overall work efficiency and management level.
[0032] The bottom of the load-bearing housing 33 is provided with a battery slot 4, which is used to store the battery that provides power to the weighing and counting component 3.
[0033] In the bolt weighing and counting mechanism, the battery slot 4 is located at the bottom of the load-bearing housing 33 to store the battery that provides power to the weighing and counting component 3. This ensures the stable operation of the weighing and counting component 3 and guarantees the accuracy of weighing and counting data. At the same time, the bottom layout saves space, making the mechanism compact and facilitating battery maintenance and replacement, thereby improving the efficiency and reliability of the mechanism.
[0034] The bottom of the load-bearing housing 33 is provided with a pad 5, which is used to provide cushioning and support for the weighing and counting component 3.
[0035] The gasket 5 ensures that a uniform contact surface is formed between the top of the bolt storage box 1 and the weighing and counting component 3, reduces local stress concentration in the bolt storage box 1, reduces the risk of bolt deformation and damage, improves the stability and reliability of the connection, and further plays a role in buffering and supporting.
[0036] In terms of buffering, when the bolt weighing and counting mechanism is subjected to external vibration, collision or impact force caused by improper operation, the gasket 5 can effectively absorb and disperse energy, reduce the impact on the weighing and counting components 3, reduce problems such as loose parts and poor contact caused by vibration, thereby extending the service life of the weighing and counting components 3 and ensuring its long-term stable operation.
[0037] The first limiting plate 21 has a first through hole array 211, and the second limiting plate 22 has a second through hole array 221. The first through hole array 211 is located directly above the second through hole array 221. The first through hole array 211 is used for the storage position and posture of the head of the limiting bolt, and the second through hole array 221 is used for the storage position and posture of the tail of the limiting bolt. The diameter of the first through-hole array 211 is slightly smaller than that of the bolt head, which can firmly hold the bolt head in place, ensuring that the bolt is in the predetermined position during storage and preventing it from shaking or shifting. A washer is placed on top of the bolt to protect the bolt head. The diameter of the second through-hole array 221 is slightly larger than that of the bolt thread to protect the bolt thread and prevent it from colliding with the second limiting plate 22 during bolt storage and retrieval, which would cause thread wear. Since the first through-hole array 211 precisely limits the bolt head and the second through-hole array 221 firmly limits the bolt tail, the two correspond to each other, so that the bolt is always arranged neatly and orderly in the bolt storage box 1, which is conducive to the efficient use of the space in the bolt storage box 1.
[0038] All the first through holes 2111 in the first through hole array 211 are circular in shape, and all the second through holes 2211 in the second through hole array 221 are circular in shape.
[0039] The first through hole 2111 and the second through hole 2211 are designed to be circular, which can well fit the shape of the bolt head and tail. The circular through holes provide a stable space for the bolt, allowing the bolt head and tail to fit tightly inside the hole. This ensures that the bolt is always in a precise position during storage and retrieval, guaranteeing the consistency of the bolt's position and posture. This helps improve the stability and reliability of the entire bolt storage system, preventing the bolt from shaking or shifting randomly inside the box. The circular design avoids additional friction and collisions caused by the bolt's shape mismatch during storage, reducing wear on the bolt surface and threads, which helps extend the bolt's service life and ensures that its performance and connection strength are not affected during shield tunnel construction.
[0040] The diameter of the first through hole 2111 is larger than the diameter of the second through hole 2211.
[0041] The diameter of the first through hole 2111 is larger than that of the second through hole 2211. This design can better adapt to the structural characteristics of the bolt. Normally, the bolt head is larger than the tail. By setting the first through hole to a larger diameter and the second through hole to a smaller diameter, the bolt can be placed in the limiting component in the correct posture. Since the bolt can be stored with the head on top and the tail on the bottom, and closely fitted with the corresponding through hole, the space of the bolt storage box can be utilized more fully. The design of different hole diameters makes the bolts arranged more neatly and orderly during storage, thereby improving the space utilization rate of the bolt storage box. This allows more bolts to be stored in the same space, which helps to improve the space management efficiency of the construction site.
[0042] The bolt weighing and counting mechanism also includes a signal interface 6, which is located inside the load-bearing housing 33. The electronic display screen 34 and the control unit 32 are connected through the signal interface 6. The signal interface 6 has good contact performance and anti-interference ability, which can ensure stable transmission of signals from the control unit 32 to the electronic display screen 34, so as to ensure real-time updates and display of information.
[0043] To facilitate understanding by those skilled in the art, the operational process of this application is briefly described as follows:
[0044] Open the battery slot 4, install the battery that meets the specifications, and then close the battery slot 4 cover to ensure that the battery is secure and not loose. Press the switch of the control unit 32. At this time, the electronic display screen 34 lights up and displays the initial status indicating that the weighing and automatic counting system has started to operate. When it is necessary to store bolts, place the bolts to be managed into the bolt storage box 1 according to their specifications and quantity, with the bolt threads facing down, through the first through hole array 211 on the first limit plate 21 and the second through hole array 221 on the second limit plate 22. After stabilization, the pressure sensor 31 automatically senses the weight of the bolts and transmits the data to the control unit 32. After receiving the data, the control unit 32 processes the received data according to the preset bolt weight parameters and algorithm to calculate the number of bolts and display the total weight and number of bolts on the electronic display screen 34.
