Abstract
The invention discloses a protective device for a back-and-forth travelling limit of a steel pushing machine. In the technical scheme, a power supply breaker of the steel pushing machine is a breaker with a shunt tripping device, and an electric magnet of the shunt tripping device is controlled by a back-and-forth protective limit; and an emergency stop button of an operation platform is connected to the breaker with the tripping device through signals. According to the invention, the power supply breaker of the steel pushing machine is changed into the breaker with the shunt tripping device to control the electric magnet of the shunt tripping device by the back-and-forth protective limit; in addition, the original emergency stop button of the operation platform is also connected to the breaker with the tripping device through signals to control and cut off the power supply of the steel pushing machine so as to protect the steel pushing machine, and an equipment accident caused by a failure in a control system is thoroughly stopped.
Description
Technical field
The present invention relates to steel production equipment field, more particularly, relate to a kind of pusher front and back travel limit protective device.
Background technology
Pusher all the phenomenon that slides down can occur every year, causes big equipment breakdown to bring adverse influence to production.Especially the spacing parking of can't cutting off the power supply when malfunctioning before and after the pusher has caused the generation of substantial equipment damage accident like this.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and travel limit protective device before and after a kind of pusher is provided.
Travel limit protective device before and after the pusher of the present invention, be achieved by following technical proposals, comprise the pusher power circuit breaker, it is characterized in that, described pusher power circuit breaker is band shunt release formula breaker, and spacing control shunt release electromagnet is protected in front and back; Suddenly stop the button signal is connected to electrical apparatus release formula breaker to operating desk.
The present invention changes the pusher power circuit breaker into band shunt release formula breaker; the spacing control shunt release electromagnet of protection before and after making also is connected to the control of electrical apparatus release formula breaker and cuts off the pusher power supply and make it accomplish protection at the anxious button signal that stops of origin operation platform in addition.Thoroughly stop the equipment breakdown that causes because of control system is malfunctioning.
Description of drawings
Fig. 1 is a band shunt release formula breaker circuit schematic diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Pusher power circuit breaker of the present invention is band shunt release formula breaker, and spacing control shunt release electromagnet is protected in front and back; Suddenly stop the button signal is connected to electrical apparatus release formula breaker to operating desk.Be with shunt release formula breaker as shown in Figure 1, M1～M4 is the pusher motor; KM1～KM4 is that electromagnetic trip short-circuiting device KA1～KA4 is the tripping coil of KM1～KM4; SB is pusher scram button (operated by rotary motion is in the operating table surface upper left corner); QXK is preceding limit switch (being arranged on the pusher trailing flank); HXK is back limit switch (being arranged on the pusher trailing flank).
The present invention changes the pusher power circuit breaker into band shunt release formula breaker; the spacing control shunt release electromagnet of protection before and after making also is connected to the control of electrical apparatus release formula breaker and cuts off the pusher power supply and make it accomplish protection at the anxious button signal that stops of origin operation platform in addition.
Embodiment recited above is described the preferred embodiment for the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design philosophy of the present invention; common engineers and technicians make technical scheme of the present invention in this area various distortion and improvement all should belong to protection scope of the present invention.
