Steel ladle framework promotes pattern, as the patent No. patent " processing the bont of bucket for the steel of RH-equipment " that is CN101081683A, for a kind of steel ladle framework bont, this ladle jacking system has two lift arms, lift arm one end is supported on ladle trunnion, and the other end is fixed on mounting, the tooth bar engagement on circle-arc tooth section and the bearing of this mounting bottom, can drive lift arm rotation, thus lifting ladle.It is large that this pattern takies ground space, and complex structure is applied less in Practical Project.
Steel ladle hoisting pattern, as the patent No. patent " a kind of ladle lifter " that is CN201250050Y, this patent comprises the winch that is fixed on ladle top and the lift frame that is fixed on winch below, on lift frame, be hinged with the hook for hooking ladle, rise ladle by winch lifting lift frame.This scheme can realize converter and RH equipment for vacuum refining layout on-line, needn't make dell, and jacking load is little, save investment, processing below, position does not have equipment, can reduce RH region security hidden danger, but winding plant, on higher platform, need certain height space, and winding plant area occupied is large.
The patent No. is the patent " steel ladle lifting device of hydraulic actuating cylinder jacking " of CN201694756U, and the patent No. patent " ladle hydraulic lifting device " that is CN201485193U, being respectively ladle hydraulic promotes and ladle hydraulic jacking pattern, similar to ladle hoisting, just actuating device replaces winch by hydraulic actuating cylinder, compare its requirement to height space of winding type lower, in some old factory transformation or because the reason factory building height conditions such as cost are limited in the situation that, can consider hydraulic pressure lift or hydraulic lifting pattern, but the ladle hydraulic of existing design promotes and hydraulic jacking device, suspension hook is shorter, promote ladle tailheaviness higher, on lift hanger or lifting-up support, need shaping-orientation device, complex structure, be not easy to installation and maintenance.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of RH in-vehicle hydraulic pressure lift ladle device, solved existing ladle jacking equipment complex structure, cost of investment high, be not easy to the problems such as installation and maintenance.
The utility model discloses a kind of RH in-vehicle hydraulic pressure lift ladle device, comprise truss frame platform, described truss frame platform is provided with mobile trolley used, described mobile trolley used below is provided with ladle hydraulic lifting device, described ladle hydraulic lifting device comprises suspension bracket and lifting hydraulic cylinder, and one end of described lifting hydraulic cylinder is connected with suspension bracket, and the other end of described lifting hydraulic cylinder is connected with mobile trolley used, described suspension bracket both sides are respectively equipped with suspension hook, and described suspension bracket and suspension hook are articulated and connected.
Further, the quantity of described lifting hydraulic cylinder is more than 2.
Further, one end of described lifting hydraulic cylinder and suspension bracket are articulated and connected.
Further, described truss frame platform is provided with and the mobile trolley used track coordinating.
Further, described ladle hydraulic lifting device also comprises suspension hook hydraulic actuating cylinder, and one end and the suspension bracket of described suspension hook hydraulic actuating cylinder are hinged, and the other end and the suspension hook of described suspension hook hydraulic actuating cylinder are hinged.
The beneficial effects of the utility model are: a kind of RH in-vehicle of the utility model hydraulic pressure lift ladle device has the following advantages:
1) can realize converter and RH equipment for vacuum refining layout on-line, can save ladle trolley turnover and wait for the handling time, reduce converter tapping across large-scale vehicling operation, enhance productivity;
2) processing below, position does not have equipment, can reduce the potential safety hazard in RH region, is convenient to settlement of accident;
3) strengthened technological flexibility, can build dell, jacking load reduces simultaneously, saves cost of investment;
4) lower to the requirement of height space, in the time that some old factory transformation or the spatial altitude that newly constructs the factory buildings have requirement, more save height space;
5) do not need lifting guide mechanism, simple in structure, few easy workout part, is convenient to installation and maintenance.
