Features
, Function
Full functions, reliable performance, advanced control system, small size, light weight, easy use and maintenance, etc. . It has the characteristics of overload shutdown protection, accident alarm display, upper and lower stroke limit control, etc. It has a manual and electric switching mechanism to automatically cut off the power supply. Both the integrated switch type and the integrated adjustment type can realize on-site and remote control functions. Outdoor type, explosion-proof protection level (special order,) instantaneous torque protection. When the opening or closing torque is momentarily pushed open, the door
will stop and not move. Even if the torque switch is momentarily pushed open and then closed,
The door
still does not move. Only by moving in the reverse direction can the over-torque protection be released. Phase loss protection has power supply phase loss and output phase loss protection functions.

Preparations before starting and closing the moving head hoist
Check content . Check whether the gate opening is at its original position. Check whether there are any floating objects blocking the gate, whether the door body is tilted, and whether the door slot is blocked. Buildings with bypass valves should check whether they are functioning properly. In frozen areas, check whether the moving parts of the gate are frozen in winter. 2. Check whether the power supply or power of the hoist is faulty. If the hoist is opened and closed manually, a sufficient number of workers must be prepared. Whether the mechanical and electrical safety protection facilities and instruments are in good condition. Check whether the oil pump, valve and oil filter of the hydraulic hoist are normal, and whether there is any oil leakage in the pipeline cylinder. , and other aspects of inspection to see if there are any ships, floating objects or other obstacles upstream and downstream that may affect the water flow. Observe upstream and downstream water levels, flows, and flow patterns. Is the vent hole blocked
Common faults and solutions during the operation of the moving head hoist, causes and solutions for the sudden stop of the hoist during operation and power outages. It should be inspected by electrical appliance specialists. If there is a large-scale power outage, a backup power supply should be activated. The fuse is blown. replace. Before replacement, check whether there is a short circuit or grounding phenomenon, and then deal with it. The limit switch malfunctions and should be readjusted. The overcurrent protector operates. It means that the motor current is too large. You should check whether the gate is tilted and whether the brake is too tight.
Installation requirements for moving head hoist
Quality assurance measures for hoist installation. When the hoist is installed, its installation position shall be controlled by a qualified crane that has been submitted to the supervisor for review. Point the longitudinal and transverse center lines and the hoist platform elevation as the benchmark, and use a hand chain hoist to make precise adjustments after rough positioning of the frame body. In addition to the control of the installation position, the hoist installation mainly controls the electrical installation and debugging of the whole machine. During electrical installation and complete machine debugging, operations must be carried out step by step in strict accordance with the instructions, relevant design and specification requirements provided by the manufacturer. The first pass rate of the installation process inspection, the first pass rate of non-destructive testing of welds, the pass rate of the previous process for delivery to the next process, and the first pass rate of final product delivery and acceptance are excellent and excellent rates. Technical measures for safe construction meet contract requirements and comply with relevant national norms, regulations and other requirements. There is no construction liability for major quality accidents, and there is no warranty liability for accidents that affect the normal use of the product. During the production process, we strictly implement the three-inspection system, highlight process control, and ensure product quality with process quality. If the previous process is not qualified, we will resolutely not enter the next process and implement a quality transfer card system for each process. Fill in quality records strictly in accordance with regulations and requirements to ensure that quality records are true, complete and complete, and that all factory information is accurate, reliable and complete.
The form and development overview of moving head hoists. According to the transmission mode, hoists are divided into mechanical transmission and hydraulic transmission. There are two major types of mechanical transmission hoists: fixed and mobile. Hydraulic transmission hoists are limited to fixed types so far. Mobile hoists using hydraulic and hydraulic transmission are still rare. Fixed machinery The transmission hoist is used for single operation or centralized operation of one machine and one door. According to the different force-bearing components of the gate, the common ones are winch type, chain type, screw type, connecting rod type, etc. Of these forms, the winch type is still the main form and is widely used in plane gates and arc gates. .
Maintenance of the moving head hoist
Maintenance is an important part of the operation and management of the gate hoist. The maintenance of the gate hoist should be based on safety first and prevention. As the main principle, regular maintenance and repairs must be carried out at any time. Nurturing is more important than repairing, and repairing is more important than robbing. , Maintenance content and technology include cleaning, tightening, adjustment, and lubrication operations. Cleaning is carried out regularly on the appearance, interior, circumferential surface of the brake wheel, electrical contacts, electromagnet suction contact surface and surrounding environment of the hoist. Doors and windows inside and outside the machine room should be cleaned once a week. Tools and tools on the site should be sorted out in a timely manner and placed neatly. Fastening is to tighten the threaded pipe joints, sealing gland bolts, etc. in the pressure oil system to prevent loosening and causing oil leakage. It also tightens various positioning bolts, high-strength bolts, wire rope compression bolts and spreaders such as foundations and flanges. Tighten the connecting bolts. If they become loose, it will change the stress and movement of the connected parts and pose a potential accident hazard. Adjustment ① Adjust the matching clearance between the bearing bush and the journal, the rolling bearing, the top and side clearance of the gear mesh, and the brake release clearance between the brake shoe and the brake wheel. ②Adjust the brake release stroke, clutch clutch stroke, safety limit switch limit stroke and gate opening and closing position indication stroke. ③ Adjust the looseness of rotating belts, chains, etc. and the elastic force of springs. ④ Adjust current, voltage, braking torque, flow pressure, speed of hoist, etc. Lubrication: All parts that move relative to each other in the opening and closing equipment must be well lubricated. Maintenance function Regularly performing necessary maintenance operations can reduce wear and tear, eliminate hidden dangers and failures, and keep the equipment in good technical condition to extend its service life, reduce operating costs, and ensure safe and reliable operation.
