Honeycomb Girder Bridge Construction Machine
1. Application range of Honeycomb Girder Bridge Construction Machine
The Honeycomb Girder Bridge Construction Machine is designed for highway and railway. According to the situation of present railway with less sub grade, more bridges and tunnels which connected too closely, our company design and manufacture the new Honeycomb Girder Bridge Construction Machine with double girder. Honeycomb Girder Bridge Construction Machine is mainly used for hoisting (lifting) of concrete girder in bridge construction (bridge building) of general railway and highway.
2. Main features and advantages of Honeycomb Girder Bridge Construction Machine
a. The first domestic creating isosceles triangle honeycomb beam, Honeycomb Girder Bridge Construction Machine has many advantages, such as light weight, high stiffness, low deflection, and high wind-resistance.
b. Unique steel pin connection, which is not only firm, but also easy to install.
c. Flexible steel legs, convenient to disasemble and transfer.
d. The frequency-converter can be installed according to the user's requirements.
e. The span can be within 60 meters , the height of hoisting is under 20 meters, the weight of hoisting is under 200 tons per hoist.
f. Honeycomb Girder Bridge Construction Machine is widely used in highway, harbor and railway construction.
3. Main mechanical manufacturing technology of Honeycomb Girder Bridge Construction Machine
There are many mechanical manufacturing (machinery-building) technologies; the rules of management of Honeycomb Girder Bridge Construction Machine are following:
a. Firstly, the technology department reviews the drawing from manufacturability.
b. Drawing up the technology guide book and making procedure qualification.
c. Making welding procedure card, mechanical manufacturing card, assembly process, camber drawing of box girder according to drawing , rules and criterion ; emphasizing the size of welding angle, geometry size and requirements of assembly etc.
d. Designing the assembly technology clamp according to the requirements of drawing.
e. Making the finishing time of manufacture and patrolling card according to the requirements of drawing; controlling the quality of manufacture strictly.
4. The installation method and steps of Honeycomb Girder Bridge Construction Machine
The Honeycomb Girder Bridge Construction Machine is the heavy duty hoisting equipment which requires very high safety. A little negligence maybe causes serious accident, therefore, the installation of Honeycomb Girder Bridge Construction Machine must be directed or installed by professional works, and the steps are following:a. surveying positioningb. paving railsc. assemble two sides main girder symmetrically.d. installing front and rear connecting framee. installing front, middle and rear legsf. installing lifting trolley and auxiliary trolleyg. hydraulic system, electrical system, operating platform and plug in power
5. Operating requirements and attention of Honeycomb Girder Bridge Construction Machine
a. Adjusting the height of transverse rails of front legs and middle legs when erecting girder or moving from one pier to keep main girder’s longitudinal slope≤0.5%，transverse slope≤0.5%.
b. The normal working wind speed should less than 6 grade when bridge girder launcher works in the open air ; when the wind exceed 6 grade, the bridge girder launcher shouldn’t moving from one pier to next pier, and components should be locked; the machine can’t work in thunderstorm day and must cut off power.
c. check the steel rope is broken or not, the circuitry leaks electricity or not, the brake is reliable or not, and after the reducers get enough lubricating oil and the oil lubricate the open gears, the machine start to work; the safe circle of steel rope on the drum shouldn’t less than 3;checking the surface and fixed parts after every shift of steel rope and making a specific check every 7～11 days;
d. the brake system of winch is allowed to start again after it checked;
e. the lifting ,longitudinal traveling and transverse traveling shouldn’t work together; the speed of lifting and translational velocity should be slowly to avoid leaning and side tumbling;
f. the goods are prohibited to throw out from bridge girder launcher strictly; it is prohibited to lift goods to pass over head strictly；it is prohibited to lift workers by hook or goods strictly；the inflammable goods are prohibited to put on the launching crane strictly;
g. After the legs move to their places, plug the safe pin to prevent the hydraulic cylinder from bearing force for a long time;
h. When the tubes of components are fault, the operator should cut off power immediately, and it is checked and repaired by the professional technician; the operator shouldn’t disassemble privately; when checking and repairing the machine , the technician must cut off the power.
i. test run and commissioning.
