Abstract
The utility model relates to an oxygen lance lifting system, comprising a drive motor, an electric brake, a speed changing device, a roller and a main command controller which are connected in turn. The utility model is characterized in that the oxygen lance lifting system also comprises a pneumatic motor, a pneumatic braking device connected with the speed changing device, and a pneumatic system arranged between the pneumatic motor and the pneumatic braking device. Through the improvement, a pneumatic motor is provided, and a set of pneumatic control system is added; thus, the oxygen lance can be lifted through the pneumatic motor under the emergency state; when the external power supply disappears, the UPS power supply in the system can be automatically put into service; only by operating the handle on the operating panel, the operating staff can conveniently control the electromagnetic reversing valve in the pneumatic lifting system; the oxygen lance can be lifted, and the purpose of avoiding accidents can be achieved.
Description
Technical field
The utility model relates to a kind of oxygen lance lifting system, the oxygen lance lifting system that has pneumatic type oxygen rifle service hoisting device that particularly can work as usual under powering-off state.
Background technology
Former converter oxygen gun jacking system comprises the fast speed motor 11 that links to each other in turn, dynamo-electric brake 12, planetary differential case 15, reel 16 and master controller 17 as shown in Figure 1; And the slow speed motor 13, dynamo-electric brake 14, planetary differential case 15, reel 16 and the master controller 17 that link to each other in turn.In converting process, damage if run into motor, accidents such as outage, the oxygen rifle just can't promote, and light oxygen rifle melting loss then is heavy then burner hearth is intake serious threat production and safety.
Summary of the invention
The purpose of this utility model is to provide a kind of oxygen lance lifting system, to solve in converting process, damages if run into motor, and accidents such as outage, the oxygen rifle just can't promote, light oxygen rifle melting loss then, heavy then burner hearth is intake, serious threat production and safe technical problem.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of oxygen lance lifting system comprises the drive-motor that links to each other in turn, dynamo-electric brake, speed change gear, reel and master controller; It is characterized in that, also comprise: a pneumatic motor; One pneumatic braking device, it links to each other with described speed change gear; One pneumatic system is arranged between described pneumatic motor and the pneumatic braking device.
Described pneumatic system comprises source of the gas, the stopping valve that links to each other in turn and has manometric pneumatic three company's parts; Commutation speed-regulating valve group links to each other with pneumatic motor with described pneumatic three company's parts respectively; Reversing valve of Xiang Lianing and throttle grverning valve group in turn, described reversing valve connect described pneumatic three and connect parts, and described throttle grverning valve group connects described pneumatic braking device.
Described pneumatic three company's parts are the strainer that links to each other in turn, reducing valve and oil sprayer, and described strainer connects described stopping valve, and described oil sprayer connects described commutation speed-regulating valve group and reversing valve.
Throttle grverning valve group comprises continuous throttle grverning vent valve and throttle grverning valve.
Described reversing valve is two position-5 way valves.
By above-mentioned improvement, a pneumatic motor is installed, and is increased by a cover pneumatic control system, just can realize in the state of accident, with pneumatic motor the oxygen rifle is promoted.After external power source disappeared, the ups power in the system was devoted oneself to work automatically, and operator promote the oxygen rifle as long as the handle on the manipulation operations panel just can be controlled the solenoid operated directional valve in the airlift system easily, reach the purpose of avoiding accident.
