Threaded Rebar Bolt
Threaded Rebar Rock Bolts(Threaded Steel Rock Bolts) are mainly used in mines where rock formations such as coal mines are not hard enough. bolts are generally used together with anchoring agents to achieve end anchoring or full anchoring in mines.
ANTO Rebar Rock Bolt is made of high-strength HRB500 or HRB600, which can provide high load-bearing capacity to protect mine safety.
Compared with other bolts, it can be installed using ordinary foreign drilling rigs, which saves installation costs.
ANTO Rebar Bolts, the threads are distributed throughout the rod body, increasing the moving length of the nut, if the anchor rod support is loose in the later stage, tighten the nut, and the anchor rod restores the support force.
The one-way left-handed rebar bolt without longitudinal reinforcement can be used in all kinds of mines and underground projects, and is especially suitable for the support of coal tunnels with wire mesh. It has achieved good technical and economic effects.
The structural features of the anchor rod: the full length of the body has a rolled continuous thread, and the full length is of equal strength; the fastening end is provided with a prestressed gasket and a ball nut. It is superior to the bolt processed by round steel, and is a new type of bolt with material saving, labor saving and equal strength.

At present, electric propulsion ships have become the focus of the development of the shipbuilding industry, and gradually replace the traditional mechanical propulsion ship. The use of electric propulsion technology can save power system space, reduce the burden on the ship, and improve work efficiency. Therefore, many of the newly built ships in the world are electric pushers. With the increase of electric push ships, the electric propulsion system is fully tested to prevent insufficient output power or performance degradation, and to ensure the stability of the entire ship power supply system, which is crucial for the safety of the electric push ship.
The electric pusher not only needs to detect the performance of the electric propulsion system, but also to check whether the power system of the whole ship can maintain stable operation when sailing at full load, especially to ensure the stability of the power control system of the central control room. In the past, shipyards generally used water load to detect ship power stations and generator sets, but the water load was afraid of bumps and mobility, and it was difficult to carry out navigation tests along the ship, and it was difficult to control power. It was difficult to carry out sudden thrust test and could not fully detect the ship power system. .
In order to solve these problems, Kaixiang Technology, the leader in China's marine power supply testing industry, launched the first high-power marine dry load in China in 2006 to replace the water load. Kaixiang marine dry load uses solid-state resistors and reactances as power consumption components. It has strong stability and is not afraid of bumps. It can go out to sea with the ship, simulate and test the performance of the ship's power system under real working conditions, thus detecting that the entire ship's power system is full. Whether it is stable under load working conditions.
Kaixiang marine dry load is greatly improved compared with the old water load and resistance box. It can complete the load test by computer software, realize the sudden unloading test, and quickly test through steady state and transient test. The key parameters such as voltage, frequency adjustment rate, volatility, recovery time, and harmonic content of the unit are taken out to visually judge the performance of the ship's power system. The software can also display parameters and curves in real time, and automatically store the test results in the database for query and printing at any time, so as to realize the intelligent and digitalization of the electric push ship detection.
Kaixiang Technology has the earliest and largest marine dry load R&D center and manufacturing base in China, and has been actively promoting the application of dry load technology in the marine field. As a national high-tech enterprise and ISO9001 international quality management system certification enterprise, Kaixiang Load has established the industry-level enterprise technology center in the industry. Its marine high-power intelligent dry load cabinet has also obtained the international advanced level scientific and technological achievements appraisal of Hebei Science and Technology Department. . So far, Kaixiang load has been applied to Jiangnan Shipyard, Huangpu Shipyard, Hudong Shipyard and other well-known domestic shipyards, and has gone abroad to serve overseas shipyards such as Singapore Keppel Shipyard and Yingshun Shipyard.
