1, the advantages of rail type container gantry crane truck walking can automatically correct the deviation, ensure the overall straight line walking container rotation, easy to load and unload container semi-trailers and cars, improve the loading and unloading efficiency of the yard. High adaptability, flexibility, adaptability to the site, not limited by the track.
2, when the deviation exceeds 215 mm, the warning is issued; When the limit position exceeds 315 mm, the limit switch will work, at this time the system stops power supply, and manual control is required to correct the deviation, press the correction button, and the truck will automatically return to normal state. The operating mechanism of door engine adopts DC transmissionSpeed control system, the analysis of the system is the use of control generator excitation, when there is a deviation into the position of the outer ring system, to achieve automatic tracking and synchronization.
3, LDH type drive device is suitable for large tonnage, large span electric single beam, hoist double beam, small gantry crane and road bridge equipment. ZDY1 (D) 21-4-0.8KW, ZDY1 (D) 22-4-5KW conical rotor brake motors, or ZDR (D) series 5KW, 2KW, 0KW conical winding rotor brake motors, etc.
4, wireless chargingpga We developed a set of absolute encoder, ABS brake, display control instrument and other main equipment composed of crane crane automatic correction system, and the research and design results are applied in the crane crane correction.
The computer was invented in 1946 by John von Neumann. February 14, 1946, the world's first electronComputer ENIAC was born in the University of Pennsylvania, and its emergence has epoch-making great significance. From the birth of the first computer to the present, computer technology has gone through the stage of mainframe, microcomputer and network.
The first computer was born in America. On February 14, 1946, the world's first electronic computer, "Electronic Digital integral Computer", customized by the United States military, came out at the University of Pennsylvania.
The first computer (ENIAC) was born in the United States in February 1946. Program storage was proposed by the American mathematician von Neumann,With funding from the U.S. War Department, development of ENIAC began in 1943 and was completed in 1946. The computer was invented in 1946. The world's first general purpose computer "ENIAC" was born on February 14, 1946, at the University of Pennsylvania. The inventors were Americans JohnW.Mauchly and J.PresperEckert.The year Intel introduced the 80286 chip, which was a leap forward from the 8086 and 8088, although itIt is still a 16-bit structure, but 140,000 transistors are integrated inside the CPU, and the clock rate is gradually increased from the initial 6MHz to 20MHz. In 1985, Intel introduced the 80386 chip, the first 32-bit microprocessor in the X86 family, and the manufacturing process was greatly improved.
CPU has more than 40 years of history from its birth to now. In 1971, the world's first microprocessor, the Intel 4004, was born. This was the grandfather of the CPU, and compared to today's CPU 4004 is pitiful, only 2300 transistorsThe processing speed is still slow, the functions are quite limited, and it lags behind today's 64-bit processing bits, Wireless charging pga He has only 4 bits. Although this CPU has not been widely used, it has opened the industry first.
