The car arrester 1 comprises a rotating shaft 4 and a car arresting bar 5 which are arranged on two tracks in a straddling mode. The rotating shaft 4 is a round shaft, and the vehicle blocking rod 5 is a rigid rod. At least one vehicle blocking rod 5 is arranged on the rotating shaft 4. In the present embodiment, three vehicle blocking levers 4 are provided in parallel on the rotating shaft 4. Specifically, one end of the car stopping rod 4 is fixedly connected with the outer wall of the middle part of the rotating shaft 5. The rotating shaft 4 can rotate around the axial center and drives the vehicle blocking rod 4 to rotate up and down. When the car stopping rod 4 is vertically connected with the rotating shaft. When the vehicle blocking rod 4 is vertical, the vehicle blocking rod is in a working position. The turning shaft 4 can be rotated counterclockwise and is in a horizontal position when the turning shaft 4 is rotated by 90 °. At this time, the vehicle stopping rod 5 is driven to rotate forwards to the horizontal direction, and is at the non-working position at this time. When the car arrester 1 is in the non-working position, when the mine car 6 moves on the track 7, the effective blocking is lost, and the mine car 6 is easy to fall too fast or fall.
The inductor 3 comprises a normally closed magnetically controlled switch. When the rotating shaft is in the working position, the normally closed magnetic control switch is in the closed state, the alarm circuit is disconnected, and when the rotating shaft is in the non-working position, the normally closed magnetic control switch is connected, and the alarm circuit is communicated. The normally closed magnetic control switch comprises: a magnetic sheet 8 arranged at the end part of the rotation shaft of the car arrester, a conductive sheet 9 arranged at the bottom of the magnetic sheet and a spring 10. The magnetic sheet 8 is fixedly connected with the rotating shaft 4, and when the rotating shaft 4 rotates, the magnetic sheet 8 rotates along with the rotating shaft. When the rotation shaft 4 is rotated counterclockwise by 90 deg., the magnetic sheet 8 is rotated counterclockwise by 90 deg. to move a distance backward. At this time, the conductive sheet 9 stays in place. The conductive sheet 9 and the spring 10 are fixed in the vacuum cylinder 11, the conductive sheet 9 and the spring 10 have weak attraction, and when the magnetic attraction of the magnetic sheet 8 to the conductive sheet 9 disappears, the conductive sheet 9 contacts with the spring 10. The conducting strip 9 and the reed 10 are connected with the alarm 2 through an alarm line. When the conducting strip 9 is contacted with the reed 10, the alarm circuit is communicated, so that the alarm 2 is triggered to alarm.
In short, when the car stopping rod 5 is in the working position, the conducting plate is attracted by the magnetic sheet and is disconnected with the reed, and the alarm does not work; when the car stopping rod is in a non-working position, the magnetic sheet is far away from the conducting sheet, so that the conducting sheet is connected with the reed, and the alarm circuit is communicated and triggers the alarm to give an alarm.
In a new embodiment, as shown in fig. 2, the sensor 3 comprises a distance sensor 12. The distance sensor 12 is used to measure the distance between the stopper rod 5 and the rail 7. When the detected distance is less than the preset distance, the distance sensor 12 sends a signal to the alarm line, so that the alarm 2 gives an alarm. Specifically, when the stopper bar 5 is vertical, that is, in the operating state, the distance of the stopper bar 5 from the rail 7 is large. The preset value can be calculated and determined through the height of the distance sensor. When the car arrester 1 is in a non-common-group state, the angle of the car arrester rod 5 relative to the horizontal plane is smaller than 90 degrees, so that the distance between the car arrester rod 5 and the track 7 is smaller than a preset value, and the position of the car arrester 1 cannot be timely and effectively monitored in this way.
Preferably, the alarm 2 further comprises a primary alarm and a secondary alarm. Wherein, the first-level alarm comprises a voice time-lifting alarm device, and the second-level alarm comprises an audible and visual alarm device. And the primary alarm and the secondary alarm are connected in parallel on an alarm circuit.
Please refer to fig. 3, which is a circuit diagram of the alarm circuit. In the figure, 13 is a power adapter, and a primary alarm 14 and a secondary alarm 15 are connected in parallel at two ends of a power supply. Wherein, the primary alarm 14 is a voice time-lifting alarm device. A first-stage switch 16 is also connected in series between the first-stage alarm 14, the second-stage alarm 15 and the power supply. In the present embodiment, the primary switch 16 is a normally closed magnetic switch. When the car arrester 1 is not in the working state, the primary switch 16 is communicated, and the primary alarm 14 and the secondary alarm 15 are communicated with a power supply.
Specifically, after being connected to the power supply, the primary alarm 14 directly sends out a voice alarm prompt. As shown in fig. 3, an audio selector 17 is also connected between the primary alarm 14 and the power supply. The audio selector 17 stores a plurality of time-raising audios, and an operator can manually select different prompting sounds.
A delay relay 18 is also connected in series between the secondary alarm 15 and the power supply. The delay relay 18 is used for performing delay processing on the communication circuit signal received by the secondary alarm 15. The time delay relay 18 can preset a time value, and when the lines of the secondary alarm 15 are connected, the time delay relay 18 starts to time. And when the preset time value is reached, the circuit of the secondary alarm 15 is communicated, and the secondary alarm is triggered to give an alarm. The secondary alarm 15 is a sound-light alarm device, and emits warning light to prompt operators in a longer distance while emitting sound, so that the grade and the range of warning are further improved.
Further, a signal relay 19 is provided between the power supply and the primary switch 16. The signal relay 19 is used to amplify the received electrical signal. In this embodiment, the electrical communication signal in the inductor 3 is weak. When the car arrester 1 is not in the working position, the communication of the alarm line cannot be timely and effectively triggered. Therefore, the signal relay 19 can effectively amplify the connection signal and the disconnection signal, thereby improving the sensitivity of the alarm line and further improving the sensitivity of the alarm system.
Further, manual change-over switches 20 and 21 are connected in series between the primary alarm 14 and the secondary alarm 15 and the power supply. The manual change over switch can be timely close corresponding alarm circuit, provide various alarm modes for operating personnel to adapt to different mine conditions, facilitate maintenance and installation.
