Technical Field
[0001] This utility model relates to the field of lifting sling technology, specifically an intelligent webbing sling with adjustable length. Background Technology
[0002] Lifting slings are flexible rigging used for lifting, transportation, and hoisting operations. They are widely used in industries such as manufacturing, construction, and logistics. Currently, lifting slings are being upgraded towards higher strength, intelligence, and lightweight design, further expanding their application scenarios.
[0003] The initial state of chemical coatings is relatively viscous and cannot be used normally. The viscosity is reduced by adding solvents (such as water for water-based coatings and thinner for solvent-based coatings) so that the coatings meet the operating requirements of specific construction tools. Existing technology ES1306418 U discloses a sling for fixing, lifting and transporting loads, including at least one cotton webbing, which is equipped with at least one temperature sensor and an associated wireless signal transmission device in conjunction with the temperature sensor.
[0004] The aforementioned slings utilize multiple temperature sensors to monitor the temperature of the cargo in real time, thereby preventing damage to the slings due to excessive cargo temperature. However, the length of the slings is fixed, thus limiting their applicability to cargoes smaller than the slings. Furthermore, the slings equipped with temperature sensors are specially designed and therefore costly. When transporting larger cargoes, additional, longer slings are required, further increasing costs. Utility Model Content
[0005] The purpose of this invention is to provide an intelligent webbing sling that can adjust the length. It uses a locking assembly to connect the first belt body, the extension belt, and the second belt body. By loosening the locking assembly, the sum of the lengths of the first belt body and the second belt body can be changed, thereby enabling it to carry goods of different sizes, thus solving the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An adjustable-length smart webbing sling includes a first lifting sling and a second lifting sling for carrying and transferring goods;

[0010] As a further technical solution of this utility model, the shell is integrally provided with sleeves at both ends on the side near the first belt body; the ends of the extension belt and the first belt body are respectively fixedly connected to the two sleeves.
[0011] As a further technical solution of this utility model, the rotating cover is integrally provided with a lever plate on the side away from the connecting shaft, and the thickness of the lever plate is less than the thickness of the rotating cover.
[0012] As a further technical solution of this utility model, the housing is provided with a placement groove for storing the dial plate on the side near the dial plate, and a second magnet is provided in the middle of the placement groove, which is embedded in the housing; a first magnet is embedded in the middle of the side of the dial plate near the second magnet, and the positions of the first magnet and the second magnet correspond to each other.

[0017] 2. In this utility model, after the rotating cover is closed, magnet one and magnet two attract each other, which can improve the stability of the connection between the rotating cover and the shell, thereby improving the stability when multiple toothed pins bite the belt body two; in addition, hook and loop fastener one and hook and loop fastener two can make belt body one and extension belt stick to belt body two, preventing belt body one, extension belt and belt body two from not being able to maintain a continuous sticking state due to their own weight.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-8 In this embodiment of the present invention, an intelligent webbing sling capable of adjusting length includes a first lifting sling 1 and a second lifting sling 2 for carrying and transferring goods 3;
[0031] The second lifting sling 2 includes a second sling body 21; the first lifting sling 1 includes a first sling body 11, one end of which is fixedly connected to a locking assembly 12, and the end of the locking assembly 12 away from the first sling body 11 is fixedly connected to an extension sling 13.
[0032] The locking assembly 12 includes a housing 121, which has a through groove on the side near the second belt 21 for the second belt 21 to pass through; a rotating cover 123 is provided on the side of the housing 121 near the second belt 21, and a connecting plate 124 is fixedly connected to the side of the rotating cover 123 near the second belt 21; a plurality of toothed pins 125 are evenly provided on the side of the connecting plate 124 near the second belt 21; and connecting shafts 120 are fixedly connected to both ends of the rotating cover 123, with the ends of the two connecting shafts 120 away from the rotating cover 123 being rotatably connected to the housing 121.
[0033] The housing 121 has sleeves 122 integrally provided at both ends of the side near the belt body 11; the ends of the extension belt 13 and the belt body 11 are respectively fixedly connected to the two sleeves 122.
[0034] The rotating cover 123 has an integrally provided dial plate 126 on the side away from the connecting shaft 120, and the thickness of the dial plate 126 is less than the thickness of the rotating cover 123.
[0035] By adopting the above technical solution, by turning the lever 126, the rotating cover 123 is rotated, thereby moving multiple toothed pins 125 away from the belt body 21. By pulling the belt body 21, the sum of the degrees of belt body 21, belt body 11, and extension belt 13 can be changed, so that belt body 11, extension belt 13, and belt body 21 can cooperate to carry and transfer goods 3 of different sizes, improving applicability. After closing the rotating cover 123, multiple toothed pins 125 can be inserted into the belt body 21, thereby fixing the position of belt body 11, extension belt 13, and belt body 21, preventing the connection between belt body 11 and belt body 21 from falling off during the transfer of goods 3.
[0036] In this embodiment, the housing 121 is provided with a placement groove 127 for receiving the dial plate 126 on the side near the dial plate 126, and a second magnet 129 is provided in the middle of the placement groove 127.

[0038] Multiple temperature sensors 22 are evenly embedded on the side of the belt body 21 away from the cargo 3; a transmitter 23 is installed at the end of the belt body 21; and a battery is installed on the outside of the belt body 21.
[0039] By adopting the above technical solution, after the rotating cover 123 is closed, magnet 128 and magnet 229 attract each other, which can improve the stability of the connection between the rotating cover 123 and the housing 121, thereby improving the stability when multiple toothed pins 125 bite the belt body 21; in addition, hook and loop fasteners 14 and 24 can make belt body 11 and extension belt 13 stick to belt body 21, preventing belt body 11, extension belt 13 and belt body 21 from not being able to stay in a sticky state due to their own weight.
[0040] As a further explanation of the above embodiments, the working principle of temperature sensor 22 and transmitter 23 is briefly described below:
[0041] I. System Overall Architecture
[0042] Multiple temperature sensors (22) and transmitters (23) on belt body two (21), as well as the positioning and communication modules in the transmitters (23), construct a three-level monitoring system of "belt body two (21) - relay node - monitoring center". The temperature sensors (22) work with the transmitters (23) to collect temperature and position data in real time, which are then aggregated by the relay nodes and uploaded to the monitoring center to realize remote and real-time monitoring of the status of the hoisting belt and cargo.
[0043] II. Hardware Configuration and Function Implementation
[0044] (a) Temperature monitoring module
[0045] Temperature sensor (22): The DS18B20 digital temperature sensor is selected, which features small size, low power consumption, and strong anti-interference ability. The measurement range is -55℃ to 125℃, and the accuracy can reach ±0.5℃, meeting the common temperature monitoring needs in logistics transportation. The sensor adopts a single-bus protocol, and only one data line is needed to realize communication with the main control chip, which is convenient for integration on the lifting sling.
[0046] Transmitter (23): Equipped with a customized signal conditioning circuit, the digital signal output by the temperature sensor (22) is amplified, filtered, and converted into a standard 4-20mA current signal or 0-5V voltage signal to enhance signal stability and transmission distance. At the same time, the transmitter has a built-in calibration module that can automatically calibrate the sensor periodically to ensure the accuracy of the measurement data.
[0047] (ii) Location monitoring module
[0048] Employing a BeiDou / GPS dual-mode positioning module, such as the UBLOX NEO-M8 series, this module supports multi-satellite system joint positioning with an accuracy of up to 2.5 meters (CEP95), enabling rapid acquisition of precise location information for lifting slings even in complex environments. The positioning module connects to the main control chip via a serial port and can output latitude, longitude, and altitude data at a set frequency (e.g., once per minute).
[0049] (III) Main Control and Communication Module
[0050] Main control chip: The low-power STM32L4 series microcontroller is selected, which has rich peripheral interfaces and can connect to temperature sensors, positioning modules, and communication modules simultaneously. By writing corresponding programs, the sensor data acquisition, processing, and packaging can be achieved.
[0051] Communication module:
[0052] Short-range communication: It adopts LoRa wireless modules, such as the SX1278 chip, which operates in the 433MHz frequency band and has strong penetration and low power consumption characteristics. The communication distance can reach 1-5 kilometers, which is suitable for data transmission between lifting slings and relay nodes in logistics transportation scenarios.
[0053] Remote communication: An NB-IoT communication module is selected, supporting low-power wide-area network (LPWAN) communication, which can directly transmit data to the cloud server. This module has advantages such as strong coverage, low power consumption, and massive connectivity, ensuring that the data of the lifting sling is stably uploaded to the monitoring center during transportation.
[0054] (iv) Power supply system
[0055] Considering the portability and usage scenarios of the lifting sling, a rechargeable lithium polymer battery is used for power supply, along with a low-power management circuit to achieve battery charge / discharge management and intelligent power switching. Simultaneously, the system supports solar charging, allowing the battery to be charged via solar panels when the lifting sling is idle, extending the equipment's runtime.
[0056] III. Working Principle
[0057] Data acquisition: Temperature sensor (22) collects temperature data of goods near belt two (21) in real time, and positioning module periodically acquires position information of belt two (21). The main control chip collects temperature and position data synchronously according to the set sampling frequency.
[0058] Data processing: The main control chip preprocesses the collected data, including data filtering and format conversion. For temperature data, it corrects the data according to the calibration parameters of the temperature sensor (22); for location data, it extracts key information (such as latitude and longitude, timestamp). The processed data is packaged and encapsulated according to a specific protocol.
[0059] Data transmission:
[0060] Short-range transmission: The packaged data is sent to a nearby relay node via a LoRa wireless module. The relay node can be deployed at locations such as logistics vehicles and warehouse entrances / exits to receive data from multiple hoisting sling terminals and perform initial aggregation and processing.
[0061] Remote transmission: The relay node uploads the aggregated data to the cloud server via the NB-IoT communication module. The monitoring center accesses the cloud server to obtain real-time information on the location of the lifting sling and the temperature of the cargo.
[0062] Data Display and Analysis: The monitoring center's management system visualizes the received data, displaying the real-time position of the hoisting sling on an electronic map and presenting cargo temperature change trends in chart form. Simultaneously, the system has a built-in data analysis module that automatically identifies and alerts to abnormal data (such as excessively high temperature or positional deviation), facilitating timely action by management personnel.
[0063] IV. Information Transmission Reliability Guarantee
[0064] Data encryption: During data transmission, the AES-128 encryption algorithm is used to encrypt temperature and location data to prevent theft and tampering. Only authorized monitoring center equipment can decrypt the data, ensuring data security.
[0065] Redundant transmission: When relay nodes transmit data to the cloud server, they employ a multi-path redundancy transmission strategy. If the primary communication link (such as NB-IoT) fails, it automatically switches to a backup link (such as 4G communication) to ensure the continuity of data transmission.
[0066] Error verification: A CRC-16 cyclic redundancy checksum is added during data packaging. Upon receiving data, the receiving end verifies its integrity using the checksum. If verification fails, a retransmission is requested to ensure data accuracy.
[0067] Network optimization: For LoRa communication, an adaptive rate adjustment mechanism is adopted to automatically adjust the communication rate based on signal strength and interference conditions, improving data transmission stability. For NB-IoT communication, base station parameters are configured appropriately to avoid network congestion and ensure timely data upload.
[0068] The working principle of this utility model is as follows: by turning the lever 126, the rotating cover 123 is rotated, thereby moving multiple toothed pins 125 away from the belt body 21. By pulling the belt body 21, the sum of the degrees of belt body 21, belt body 11, and extension belt 13 can be changed, so that belt body 11, extension belt 13, and belt body 21 can cooperate to carry and transport goods 3 of different sizes, thus improving applicability. After closing the rotating cover 123, multiple toothed pins 125 can be inserted into the belt body 21, thereby fixing the position of belt body 11, extension belt 13, and belt body 21, preventing the connection between belt body 11 and belt body 21 from falling off during the transport of goods 3.
[0069] After the rotating cover 123 is closed, magnet 128 and magnet 229 attract each other, which can improve the stability of the connection between the rotating cover 123 and the housing 121, thereby improving the stability when multiple toothed pins 125 bite the belt body 21; in addition, hook and loop fasteners 14 and 24 can make belt body 11 and extension belt 13 stick to belt body 21, preventing belt body 11, extension belt 13 and belt body 21 from not being able to stay in a sticky state due to their own weight.
[0070] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
