Technological innovation breaks through again! Jinan Liling WAA-1200G static load tensile testing machine is newly released, which enables high-precision detection of mining support materials.

Recently, Jinan Liling Testing Machine Co., Ltd. launched a brand-new WAA-1200G static load tensile testing machine based on years of research and development of mechanical testing equipment. This model focuses on the testing requirements of mechanical properties of mining support materials such as anchor bolts, anchor cables and rebar, integrates a number of independent innovation technologies, and has the advantages of high precision, high safety and intelligent operation. It is fully suitable for multi-scene standardized tests in coal mines, construction materials, scientific research institutes and third-party testing institutions, and provides reliable hardware support for mine support safety and material quality control.
As a high-tech enterprise deeply involved in Jinan testing machine industry, Jinan Liling has always focused on detecting pain points in the industry. In view of the problems of traditional large-tonnage tensile testing machine, such as complicated operation, insufficient protection, limited control accuracy and large sample fracture impact, the R&D team completed the all-round upgrade of the whole machine structure, servo hydraulic pressure and electrical measurement and control system, and created this 1200kN six-column static load tensile testing equipment, and a number of innovative designs filled the gap in the practical upgrade of the industry.
Multiple core innovations to create differentiated competitive advantages in the industry
1. Split intelligent measurement and control system, which greatly improves the convenience of operation.
The equipment is equipped with self-developed YQ300H all-digital closed-loop external independent controller, and adopts USB high-speed data transmission, which can adapt to desktop, notebook and tablet terminals. Equipped with multifunctional hand-held controller, it can independently control the beam lifting, jaw clamping loosening and emergency stop on site, and the sample clamping does not need to go back and forth to the console, which greatly reduces the manual operation intensity. The measurement and control software is equipped with DSP neuron adaptive algorithm, which supports the smooth switching of three closed-loop modes of force, deformation and displacement, and has the functions of data networking and remote control. The test curves and mechanical data are automatically stored and exported, which completely matches the national standard data acquisition specification.
2. The whole machine structure is optimized, stable and durable, and the safety protection is full.
The main engine adopts 6-column high-strength structure (4 columns+2 precision T-screw), and the upper and lower jaws have built-in hydraulic clamping structure, so that the sample clamping is stable in the center and the fracture alignment is excellent; The bottom of the lead screw is equipped with elastic damping mechanism, which greatly counteracts the fracture impact of the sample and reduces the noise of the equipment. The flexible dust cover is installed outside the lead screw to prolong the service life of the transmission parts. The whole machine is equipped with three-sided punching cold-rolled steel plate safety shield as standard, which prevents debris from splashing during the test and does not block the observation field of vision at the same time, ensuring the safety of experimenters in all directions. The servo pump station adopts imported cartridge valve differential pressure servo technology, which has the advantages of quiet operation, less heat dissipation, energy saving and environmental protection. The main oil pump and hydraulic valve parts are all made of first-line brand accessories such as Mazuqi, ABB and Huade, and the hydraulic system runs stably and reliably.
3. The whole process of electrical safety protection, stable and worry-free operation.
The equipment has built-in exclusive operation monitoring system, which integrates the functions of phase sequence, automatic self-inspection in case of lack of phase, multiple protection functions of electrical overcurrent and overload, and real-time visualization of system pressure and clamping pressure with real-time oil pressure monitoring instrument, so as to avoid the risk of circuit and hydraulic failure in advance and adapt to long-term uninterrupted quality inspection conditions.
High-precision parameters, meet the requirements of multi-standard and rigorous detection.
The WAA-1200G has a maximum test force of 1200kN, the accuracy of the whole machine reaches 0.5, and the full-scale resolution of force and deformation can reach 1/500,000 of the full scale, so the fault can be measured without precision without step. Force control, deformation control, displacement control multi-mode speed regulation accuracy can reach 0.2%, displacement resolution is 0.01mm, and the measurement performance is better than the national standard requirements. The equipment can complete a full set of mechanical tests such as metal tension, compression and bending, and automatically calculate the core indexes such as tensile strength, yield strength, elastic modulus and elongation, which fully meet the relevant standards of GB/T 228.1, JJG 139, MT/T mine anchor cables and ASTM international testing specifications.
Equipped with multi-specification special tooling accessories, rebar jaws cover φ 13-φ 45 mm, steel strand jaws adapt to φ 9.5-28.6 mm full mainstream specifications, built-in hydraulic automatic clamping device, and φ Φ160mm compression platen, one device can complete the static load test of various mining supporting components such as anchor rod, anchor cable, steel strand and rebar, and reduce the input cost of laboratory equipment by multiple purposes.
The size of the whole machine is 900×760×2880mm, the weight of the whole machine is about 4500kg, and the power supply is 380V in tn-s. The complete set of main engine, servo oil source, measurement and control system, special fixture and tool spare parts are delivered. Many rounds of precision calibration and fatigue test are completed before leaving the factory, and a full set of quality inspection reports and operation training materials are attached.
Deeply cultivate the testing equipment track and continue to help upgrade domestic equipment.
Jinan Liling Testing Machine Co., Ltd. is located in Jinan, the capital of testing machines in China. It integrates R&D, production, sales and after-sales, focusing on the R&D and manufacturing of hydraulic universal testing machines, static load tensile testing machines and material mechanics testing equipment. Its products widely serve major coal mines, construction engineering enterprises, university laboratories and third-party quality inspection centers in China. The landing of WAA-1200G new products is a special technical achievement of the company aimed at the needs of deep mine support detection, which effectively solves the industry pain points of insufficient precision, poor safety and low intelligence of large-tonnage support material detection equipment, and promotes the localization and intelligent upgrade of mine detection equipment.
The person in charge of the relevant technology of the company said: "In the future, Jinan Liling will continue to dig deep into the needs of mining and construction materials testing scenarios, continue to iterate servo control and intelligent measurement and control technologies, and constantly introduce high-precision and high-reliability testing equipment to replace imported equipment with domestic high-quality testing machines, providing strong testing guarantee for domestic engineering quality and safety and new material research and development."
