For more details you can to Shenzhen Hengtai state vocational training schools, corporate official website: http: //htbjypx.shop.liebiao.com/ known building construction elevator construction elevator is manned cargo building frequently used construction machinery, due to its unique cabinet structure makes it both comfortable and safe ride, lift construction on the site with the crane usually used generally in 1-3 deadweight tons, running at 1-60M / min. Many different types of construction hoist, according to the presence or absence of starting operation mode for heavy weight and there are two, according to the control mode into manual control type and automatic control type. You can also add as needed frequency devices and PLC control module, you can also add additional floors Hu called means peace layer devices. Construction elevator construction principles, features: lift workers to adapt to the bridge, chimney tilt construction needs, which according to building shape, the rail gantry tilt installation, while maintaining the level of hoists, rack rails run along the incline. The reason can be manned elevator construction, mainly due to its anti-fall safety device is equipped, greatly improving the safety factor. Rack and pinion currently widely used in the construction site of transmission of people and goods dual construction elevator, is equipped with a drum-shaped bevel progressive anti-fall safety device. Bevel gear drum progressive anti-dropping security mainly by the gears, centrifugal speed limiting device and tapered drum brakes composition, when the protection objective (construction lift cage) downlink speed reached calibrated operation speed, its centrifugal limit Rejection block shift gear device (quite pawl), driven cone drum (quite ratchet) to the brake Belt Movement, contacts and brake torque, while the disc spring stack is compressed, the compression of the size measured by calculating available Analyzing the braking distance when the rated brake load. People's Republic of China Building Industry Standards "construction hoist drum gear cone progressive anti-fall safety device" (JGl21-2000) states that "the construction elevator fall protection safety device can only be used within the effective inspection period. Safer and effective test period shall not exceed two years. safety device, whether used or not, after the expiration of valid test calibration must be re-examined. construction lift anti-fall safety device lifetime of five years. "In order to ensure the safe use of the lift construction, at present, Some of the provisions of domestic cities construction elevator fall protection safety device after factory, the initial survey period not exceeding two years and annually thereafter, and whether to use it or not, the test cycle to be inspected, the factory for five years be scrapped. Construction lifts anti-fall safety device test calibration test stand by the variable speed device, torque and speed sensor, torque and speed microprocessor-based instrument, construction elevator fall protection safety device performance tester, graphics printer and other components. Calibration before testing, the first construction lift anti-fall safety device speed centrifugal device and the cone drum brake unbundled, check the safety device speed limiting device components: pellet, centrifugal seat, shrapnel, spring and adjustment bolts good, action is normal, remove oil, rust. Tapered drum brake parts, checking large copper nut, screw, cone drum, disc springs, indicating pins, etc. is intact, functioning properly, remove oil, rust. Construction elevator fall protection safety device calibrated test items altogether five: 1. Calibration operation speed measurement, the operating speed should meet the standard requirements; the safety gear, centrifugal speed limiting device mounted on a test bench using variable speed devices, test equipment, safety devices limit the centrifugal action open gear speed when it is set for the selected operating speed.
