Jinan Liling LJZ-100W corner high-strength bolt detector, short bolt gospel, help steel structure detection standardization upgrade.

Recently, Jinan Liling Testing Machine Co., Ltd. officially launched LJZ-100W microcomputer-controlled high-strength bolt detector with corner method. The equipment was developed and manufactured in strict accordance with the national standard GB50205-2020 "Code for Acceptance of Construction Quality of Steel Structures", and a brand-new independent measurement and control system was integrated to realize full-automatic and high-precision detection of torque, axial force and torque coefficient of high-strength bolt connection pairs, providing a one-stop intelligent mechanical detection solution for steel structure processing plants, third-party detection institutions and construction engineering supervision units.
With the rapid development of long-span stadiums, bridges, wind power towers and assembled steel structures in China, the fastening performance of high-strength bolt connection pairs directly determines the overall structural safety, and the industry puts forward higher requirements for the accuracy, automation and data traceability of bolt detection equipment. The LJZ-100W tester released this time is optimized and upgraded for detecting the pain points of large hexagonal high-strength bolts. The maximum torque of the whole machine is 100Nm, the torque measuring range is 1-100Nm, the accuracy of the tester reaches level 1, the relative error of the torque indication is controlled at 1%, the torque resolution can reach 1/500,000 of the full scale, and the torque speed is continuously adjustable from 360 to 720/min, covering the length of 65-120mm perfectly.
The equipment is equipped with self-developed LLG-Testing TTC measurement and control software, adapted to Windows XP/Win7 operating system, and the software and hardware cooperate to realize digital control of the whole process. During the test, the data of torque, axial force, torsion angle and rotation angle can be collected synchronously in real time, and multiple curves of torque-axial force, torque-time and torque coefficient can be generated dynamically, which supports curve scaling and local data analysis. Built-in multiple intelligent judgment logic, the axial force reaches the standard limit and automatically stops and reverses to loosen the sample. When the sample breaks and the torque drops sharply, the system automatically judges the fracture and terminates the test. It is equipped with sensor overload protection and peak keeping monitoring functions to avoid the risk of equipment overload damage.
Intelligent data processing is the core highlight of this model. After the single-group test is completed, the software automatically calculates the key indexes such as average axial force, average torque, average torque coefficient, standard deviation and coefficient of variation of multiple groups of specimens in batches. All test data are stored locally in the form of database, which supports retrieval, retrieval and batch export at any time; With a visual report editor, users can customize the test report template, print standardized test documents with one click, and completely retain the test data to realize the whole quality traceability. The system supports three-point independent calibration of torque sensor, axial force sensor and angle encoder, and the calibration parameters can be derived from the backup and reloading of config file to avoid repeated calibration, which greatly reduces the equipment operation and maintenance cost.
At the operation level, both ease of use and professionalism are taken into account. The software interface is divided into four modules: digital display panel, curve visualization panel, sample information input panel and speed control area, which supports batch new sample records and sample template import, and batch inspection of the same batch of bolts does not require repeated input of parameters. Built-in GB50205 national standard testing standard library, which can add, import and export industry testing standards as needed, and adapt to the testing specifications in many fields of architecture, bridge and machinery manufacturing; Hierarchical user authority management, real-time wiring schematic diagram and supporting video teaching documents reduce the threshold for operators to get started, and ordinary staff can independently complete the whole set of testing processes in a short period of training.
The hardware of the whole machine adopts 1.0kW servo drive motor, with 220V standard power supply. The size of the machine body is 1300mm×500mm×600mm, and its weight is 500kg. The structure is stable and deformation-resistant, and the long-term test maintains stable measurement accuracy. The equipment comes with complete packing accessories, electrical wiring drawings and a complete set of operating instructions. The manufacturer provides technical support for the 0531-88277566 special line, covering the whole cycle of equipment installation and debugging, software training, annual calibration and after-sales maintenance.
According to experts in the industry, LJZ-100W corner high-strength bolt detector takes into account the three core advantages of high precision, full automation and digital storage, and fills the short board of intelligent detection in small and medium-sized testing laboratories, effectively solving the industrial problems such as large error in traditional manual detection, difficult data retention and cumbersome report production, promoting the standardization and digital transformation of domestic steel structure high-strength bolt detection process, and building a strong detection defense line for the quality and safety of building steel structure engineering.
At present, this detector has been fully open for ordering, and can be widely used in steel structure production enterprises, third-party quality inspection centers, quality inspection stations for residential construction projects, rail transit and wind power equipment manufacturing enterprises, providing integrated delivery services of the whole machine, customized tooling and supporting measurement and control software.
