Abstract
The invention discloses a maintenance trolley for a vacuum chamber. The maintenance trolley comprises a trolley (1) positioned on a track on the upper part of the vacuum chamber, a suspension cage (2), a hoister (4) installed on the trolley (1), a steering pulley (5), a rolling wheel group (10) and an electric control device (8). Wherein, a transmission rope (3) is arranged between the hoister (4) and the suspension cage (2), with one end coiled on the hoister (4), and the other end connected to the suspension cage (2) after passing through the steering pulley (5) and the rolling wheel group (10) in order. The suspension cage (2) is provided with a protector (11), and a protection rope (6) is positioned between the trolley (1) and the suspension cage (2). Specifically, one end of the protection rope (6) is fixed on the trolley (1) and the other end of the protection rope (6) is connected to the protector (11). With simple structure and low cost, the maintenance trolley of the invention also has good usability and security, and is convenient for maintenance.
Description
Technical field
The present invention relates to a kind of maintenance trolley for vacuum chamber.
Background technology
The general employing of adiabatic liner repair and replacement in the molten steel stilling chamber of steelworks set up scaffold at present.The workman enters in the vacuum chamber and reaches service materials such as manual delivery fire brick up and down by climbing scaffold, vacuum chamber is keeped in repair, caused a lot of inconvenience to maintenance, not only work capacity is big for this, also need the long duration, waste a lot of labour powers simultaneously, consumed a large amount of financial resources again.
Summary of the invention
The present invention relates to a kind of maintenance trolley for vacuum chamber, it is not only simple in structure, and cost is low, and usability and safety are good, are convenient to keep in repair.
The present invention has adopted following technical scheme: a kind of maintenance trolley for vacuum chamber, it comprises chassis, cage, chassis is positioned on the track on vacuum chamber top, on chassis, be provided with winch, deflection sheave, rolling wheels and electrical controller, be provided with fly rope between described winch and the cage, one end plate of described fly rope is on winch, and the other end is successively by linking to each other with cage behind deflection sheave, the rolling wheels; Described cage is provided with protector, is provided with protection rope between described chassis and cage, and the described protection end of restricting is fixed on the chassis, and the other end links to each other with protector on the cage.
The side of described chassis is connected with power supply slip maintenance suspension bracket, is provided with the trolley running device on chassis; Be provided with interlock system between described cage and the chassis; Described interlock system is a drg, and drg is positioned on the winch, and described drg is set to automatic load sustaining brake or hydraulic block drg; The bottom of described cage is provided with the energy disperser fender guard; The top of described cage is provided with lifting limiting and protecting device and rope broken protector; Described winch is provided with the stressed overload limiting protector of level; The door of described cage is provided with the door opening electrical outage fender guard; Column is provided with the radius stay setting device around the described cage.
The present invention has following beneficial effect: chassis of the present invention is across a plurality of molten steel vacuum chambers, such chassis can be many molten steel vacuum chambers and keeps in repair, adopt chassis that vacuum chamber is keeped in repair, the staff takes the materials such as fire brick of cage together with maintenance usefulness, and together maintenance works such as changing fire brick is easily finished in lifting in vacuum chamber.Maintenance trolley for vacuum chamber is not only simple in structure, protects completely, and safety performance is good, and the cost of overhaul is low, the saving of labor, laborsaving, save time, save the duration, than adopting the scaffold handling labor can improve work efficiency 6-8 doubly, guarantee safe and reliable again.
