Abstract
The utility model provides a furnace lid position control device for a soaking pit furnace lid opening machine. The furnace lid position control device comprises a motor, a speed reducer, a transmission shaft (1), a cam controller (4), an eccentric wheel and an electric control system, wherein the motor is connected on the speed reducer through the transmission shaft, the eccentric wheel is positioned on the transmission shaft (1) extending out from the speed reducer to control a furnace lid to go up and down, the cam controller (4) can monitor rotation position of the eccentric wheel and can send position signals to the electric control system, and the electric control system can control the motor to start and stop automatically according to signals of the cam controller (4). By means of the structure of the position control device, accurate location can be achieved when the lid opening machine lift the furnace lid to an upper stopping point and descends to a lower stopping point.
Description
Technical field
The utility model relates to a kind of position control, relates in particular to a kind of position control of the process that hoists for the soaking pit cover carriage.
Background technology
In metallurgy industry, adopt in the process of soaking pit heating, the shove charge of steel ingot and come out of the stove and all need to open soaking furnace lid, cover carriage moves at the rail of hole in soaking pit both sides, it comprises two actions in whole process of taking off lid: (1) vertically operation bell is mentioned or puts down; (2) translation operation with bell from a position translation to another position.Vertically operation mainly is subjected to the control of lifting mechanism.
Existing cover carriage is in the process of hoisting, need the stroke of Artificial Control lifting mechanism and stopping of the highest and extreme lower position, but the body of cover carriage blocks the operation sight line easily in the actually operating, thereby cause hoisting, in the down maneuver process, the operative employee can't see the position of soaking furnace lid, and then causes the mishandle frequent occurrence.
Therefore, those skilled in the art making great efforts to seek always a kind of can be in the lifting mechanism working process, automatically realize the control device that stop position up and down stops.
Summary of the invention
It is a kind of in the lifting mechanism working process that the purpose of this utility model is to provide, and can realize self-braking position control at stop place up and down.
To achieve these goals, the bell position control of a kind of soaking pit cover carriage described in the utility model includes motor, step-down gear, transmission shaft and cam operated contoller, eccentric wheel, electrical control system; Described motor is connected in described step-down gear by transmission shaft; Eccentric wheel is arranged at from step-down gear transmission shaft out, with rising and the decline of control bell; Cam operated contoller is monitored eccentric position of rotation, and position signal is sent to electrical control system; Electrical control system is according to the signal control motor start and stop of cam operated contoller.
Further, described position control also includes shaft coupling, flanged shaft and stopper, described speed reducer output shaft is connected in transmission shaft by shaft coupling, and the transmission the tip of the axis is linked in an end of flanged shaft, and the other end of described flanged shaft is connected with cam operated contoller by shaft coupling; Described transmission shaft is used for supporting eccentric wheel, and described motor, stopper and electrical control system are electrically connected.
Adopted the position control of said structure, realized that cover carriage is in the accurate location that bell is lifted to top dead center and is reduced to lower dead center, further avoided manually-operated inaccuracy, and reduced workman's working strength, prolonged the work-ing life of bell, soaking pit fire door and sand seal device.
Description of drawings
Fig. 1 is the structural representation sketch of the position control of soaking pit cover carriage lifting mechanism described in the utility model;
Embodiment
In order better to understand the purpose of this utility model, feature and function are described in detail structure and the function of preferred implementation of the present utility model below in conjunction with accompanying drawing.
Metallurgy industry, the cover carriage of soaking pit includes travel mechanism and lifting mechanism, and described travel mechanism is in order to do translational movement along the rail of hole in soaking pit both sides; Described lifting mechanism is in order to open (lifting) and to cut out (decline) soaking furnace lid.Described travel mechanism has the dolly body and is arranged on the dolly body and along the wheel of the orbital motion of soaking pit space for collecting ashes in a stove both sides.Described lifting mechanism includes a bell position control, and this bell position control includes motor, stopper, step-down gear, transmission shaft 1, cam operated contoller 4, eccentric wheel and electrical control system (the not shown in the figures meaning out); Described motor is connected in described step-down gear by transmission shaft 1; Described stopper is arranged on the shaft coupling between described motor and the described step-down gear; Described eccentric wheel is arranged at from step-down gear transmission shaft 1 out, with rising and the decline of control bell; Described cam operated contoller 4 is monitored eccentric position of rotation, and position signal is sent to electrical control system; Described electrical control system is according to the signal control motor start and stop of cam operated contoller 4.Further, the output shaft of described step-down gear is connected with transmission shaft 1 by shaft coupling, and described flanged shaft 2 one ends are connected by screw in transmission shaft 1 end, and described flanged shaft 2 the other ends are connected with cam operated contoller 4 by shaft coupling 3; Described transmission shaft 1 is used for supporting eccentric wheel and passes through its rotation of key control, described motor and electrical control system are electrically connected, control its working order by electrical control system, described cam operated contoller 4 is positioner, it is in order to send signal in the startup of electrical control system and then control motor and to stop, concrete, when eccentric wheel rotates on the top dead center position of lifting mechanism or bottom dead center position, described cam operated contoller 4 sends signal in electrical control system, described electrical control system received signal also further sends signal in motor and stopper, so that motor shuts down with accurate location raised position.
The above only is a kind of preferred implementation of soaking pit cover carriage described in the utility model; should be pointed out that for those skilled in the relevant art, under the prerequisite that does not break away from the utility model principle; trickle modification and the improvement made also should be considered as belonging to protection domain of the present utility model.
