Description
Technical Field
The utility model relates to a chevron shape emergency exit magnetism switch signal blocking aggregate unit, the switch signal blocking device of concretely relates to cage chair, emergency exit linkage can be in the field wide application such as mine shaft pit shaft promotion.
Background
Mine lifting in the underground mining process is an important link of the operation of the whole mine, a shaft is more important as a throat part of the mine, and bears tasks of lifting personnel, ores, equipment carrying and the like, wherein the safety door is used as shaft equipment and is always the focus of attention of people, whether the operation of the shaft mouth safety door is safe or not is directly related to whether the life safety of the personnel is guaranteed or not, and the falling accident of the personnel is caused because the shaft mouth safety door is not closed in time.
Mine well head emergency exit form is various, including hand-pulling type, pneumatic type, linear electric motor formula, fluid pressure type, and the present multi-purpose chevron shape fluid pressure type emergency exit of metal mine moves the assigned position when the cage, touches the sensor that targets in place of well head about, and the sensor establishes ties with signal system, and the signal lamp is bright, and the emergency exit can be opened. When people enter or object enter operation is finished in the cage, the operator presses the closing button, and the safety door is closed. The cage begins to transfer or promote, leaves the sensor position that targets in place, and the signal lamp goes out, also can not open if operating personnel's malfunction emergency exit appears, targets in place until the cage, switches on the signal circuit again.
At present, the switching of emergency exit is controlled through workman manually operation to traditional emergency exit, and the emergency exit often appears closing untimely or closing untight condition when rotatory is closed, leads to promoting signal delay or two emergency exits clearances too big, has produced certain potential safety hazard. Therefore, the reliable switch signal locking linkage device is a reliable guarantee that the safety of a lifting system is protected and the falling accident is avoided.
Disclosure of Invention
The utility model aims at providing a safety door that exists to prior art often appears closing untimely or close not tight the wait condition when rotatory closing, and provide a safe, reliable chevron shape emergency exit magnetic switch signal shutting aggregate unit to effectively solve the unsafe factor that mine emergency exit exists, can realize that the emergency exit is closed and will not form the response when not tight, promote the signal and will not send, thereby ensure the safety of mine promotion in-process effectively.
In order to realize the above object of the utility model, the utility model relates to a chevron shape emergency exit magnetic switch signal shutting aggregate unit adopts following technical scheme:
the utility model relates to a chevron shape emergency exit magnetic switch signal shutting aggregate unit contains a pair of stand and installs a pair of emergency exit at two stand upper portions positions respectively, magnet is installed in the lower part of the door frame stand of one of them emergency exit, electromagnetic proximity switch is installed to the corresponding position in the lower part of the door frame stand of another emergency exit, magnet and electromagnetic proximity switch horizontal induction distance control are within 25mm, electromagnetic proximity switch links to each other with the signal line, the signal line passes through the ribbon to be fixed on the emergency exit and is connected to hoist control system.
The magnet and the electromagnetic proximity switch are fixed on the lower portion of the door frame stand column in a welding mode, the distance between the magnet and the electromagnetic proximity switch is 8-12 cm from the bottom of the door frame stand column, the magnet is vertically installed, and the electromagnetic proximity switch is horizontal and installed corresponding to the magnet. The electromagnetic proximity switch is a 24V electromagnetic proximity switch. Increase the utility model discloses behind the device, magnet and 24V electromagnetism proximity switch will not form the response when the emergency exit is closed not tight, and the lifting signal will not send.
The utility model relates to a chevron shape emergency exit magnetic switch signal shutting aggregate unit has solved the unsafe factor that former emergency exit exists effectively after adopting above technical scheme, can realize that the emergency exit is closed not tight, promotes the purpose that the signal will not send, has ensured the safety problem effectively, has following beneficial effect:
(1) the utility model discloses having add magnet and electromagnetism proximity switch, the electromagnetic induction signal is sensitive, has guaranteed pit shaft safe operation, has solved because of the emergency exit closes the safety problem that not strict causes.
(2) Simple structure, convenient processing and installation.
(3) Safe, reliable, economical and practical, and ensures the safe and efficient operation of shaft facilities.
Drawings
Fig. 1 is a schematic view of the structural connection of the magnetic switch signal locking linkage device of the herringbone safety door of the present invention.
The reference signs are: the method comprises the following steps of 1-upright post, 2-safety door, 3-magnet, 4-electromagnetic proximity switch, 5-signal line, 6-door frame upright post and 7-elevator control system.
Detailed Description
For further description of the present invention, the following detailed description will be made on a magnetic switch signal blocking linkage device of a herringbone safety door according to the present invention with reference to the accompanying drawings and embodiments.
In the process of actually lifting a shaft into and out of a vehicle, when people entering or object entering operation is finished in a cage, an operator presses a closing button, a hydraulic station electromagnetic valve acts to control a hydraulic station oil pump to drive an oil outlet of a hydraulic motor on a safety door through a valve bank to transmit power, the safety door is closed through chain transmission, and a lifting signal is sent through electromagnetic induction.
By figure 1 the utility model relates to a chevron shape emergency exit magnetic switch signal shutting linkage's structural connection schematic diagram sees, the utility model relates to a chevron shape emergency exit magnetic switch signal shutting linkage is formed by a pair of stand 1, a pair of emergency exit 2, magnet 3, 24V electromagnetism proximity switch 4, signal line 5, door frame stand 6, the combination of elevator control system 7. The safety door 2 is arranged at the upper part of the upright post 1, the upright post 1 and the safety door 2 form an integrated structure in a welding mode, and the safety door 2 is also connected with the doorframe upright post 6 in a welding mode; magnet 3 is vertical to be installed in the lower part position of the door frame stand 6 of an emergency exit 2, apart from the bottom 10cm of door frame stand 6, 24V electromagnetism proximity switch 4 horizontal installation is in the lower part of the door frame stand 6 of another emergency exit 2 to correspond with magnet 3, magnet 3 and the control of electromagnetism proximity switch 4 horizontal induction distance are within 25mm, electromagnetism proximity switch 4 links to each other with signal line 5, signal line 5 passes through the ribbon to be fixed on emergency exit 2 and is connected to hoist control system 7. Through power transmission, after the safety door 2 is tightly closed in a rotating mode, the magnets 3 and the 24V electromagnetic proximity switch 4 immediately generate induction signals, the induction signals are transmitted to the elevator control system 7 through the signal wire 5, finally lifting signals are sent out, and the magnetic switch signal locking linkage of the herringbone safety door is completed.
