The utility model discloses can effectively avoid because of the serious accident that individual personnel responsibility heart is not strong can not in time pull up take advantage of people's platform and cause.
Description
Technical Field
The utility model relates to an alarm device, concretely relates to main shaft skip manned platform automated inspection audible-visual alarm device.
Background
The existing coal mine main shaft hoisting mostly adopts a vertical shaft tower type multi-rope friction hoist, the power of a winch main motor is 2600kW, the maximum hoisting speed is 10m/S, the hoisting cycle time is 94S, and the control is the AC-DC-AC variable frequency speed regulation control. The main shaft hoisting system is an important component in mine production, carries the coal hoisting task of the whole mine and is also used as a standby channel for hoisting personnel. The third hundred and eighty rules of coal mine safety regulations: the person lifting in the shaft should use a cage or a skip with a platform for carrying people. When the auxiliary shaft lifting system breaks down or is overhauled greatly, the main shaft lifting system needs to undertake a person lifting task, and the person carrying platform in the main shaft skip bucket is put down to meet the needs of lifting personnel.
In the use process, occasionally, the situation that the operator does not timely pull up the manned platform after the personnel finish lifting, and the loading and unloading driver does not confirm to directly load coal into the skip bucket before lifting the coal occurs, so that the manned platform is slightly damaged, and the balance tail rope, the skip bucket and shaft equipment are seriously damaged, so that major electromechanical accidents are caused, and the safety production of a mine is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, and then provide a main shaft skip takes advantage of people platform automated inspection audible-visual annunciator, this alarm device can effectively avoided because of the serious accident that individual personnel's responsibility heart is not strong to fail in time to pull up and take advantage of people platform and cause.
The utility model adopts the technical proposal that: a main shaft skip man-riding platform automatic detection sound-light alarm device comprises an infrared sensor, a relay K and a relay K1Relay K2The device comprises an indicator light and an acousto-optic alarm device; the infrared sensor and the relay K1Are connected with each other, the relay K1The normally closed contact is connected with the normally open contact of the relay K in series and is used for controlling the relay K2Said relay K2The two pairs of normally open contacts respectively control the indicator light and the acousto-optic alarm device.
Further, the infrared sensor comprises an infrared transmitter and an infrared receiver, and the infrared transmitter and the infrared receiver are respectively installed on two sides of the skip and used for sensing the position of the skip.
Further, the relay K1And relay K2DC24V relays are used.
The utility model discloses the beneficial effect who produces is: the utility model discloses perfect solution potential hidden danger, if appear taking advantage of the people when the platform is not pulled up, the uninstallation operation panel pilot lamp is bright, and audible-visual alarm device sends out the police dispatch newspaper simultaneously, only takes advantage of the people platform and pulls up the back, just can remove the police dispatch newspaper, provides the guarantee for main shaft hoisting system's safe and reliable operation. On the premise of fully utilizing original devices and circuits of a signal system, only small electrical equipment such as a relay, an audible and visual alarm device and the like is added, the input manpower and material resources are extremely small, the production task can be ensured to be completed more smoothly, and the production efficiency of a mine is improved.
Drawings
Fig. 1 is a working principle diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the working principle of the present invention is: when the skip reaches the 'flush', a pair of infrared sensors SQ including an infrared transmitter and an infrared receiver are installed at both sides of the skip, so that the infrared sensors SQ control a DC24V relay K installed in a main shaft tower three-floor distribution box1Then using a relay K1Is connected in series with a pair of normally open contacts of a 'flush' relay K in the signalling system to control a DC24V relay K placed in the control box of the unloading station2Then through a relay K2The two pairs of normally open contacts respectively control an indicator lamp L on the operating platform and an external sound-light alarm device Q.
In the lifting process, the infrared sensor SQ firstly detects whether the passenger platform is pulled up, then the skip bucket reaches the 'flush' position, and the sequence relation exists, so that the detection device has no false alarm phenomenon. Relay K1、K2The on-off condition is as follows: when the skip bucket reaches the 'flush' position, the original relay K of the signal system is electrified and closed, and the normally open contact of the signal system is connected. If the manned platform is pulled up, the infrared transmitter and the receiver are blocked, and a relay K1When the power is on and the normally closed contact is disconnected, the relay K is started2Can not be switched on, relay K2The controlled indicator light L and the sound-light alarm device Q do not act; if the manned platform is not pulled up, no barrier exists between the infrared emitter and the receiver, and the relay K1When the relay is not operated, the normally closed contact is switched on, and the relay K is started2When the electric power is turned on, the buzzing indicator lamp of the sound-light alarm device Q is turned on, and an alarm is given to remind an unloading driver of not pulling up the passenger platform in time.
The utility model discloses a theory of operation is clear, and logical relation accords with actual conditions, and excellent in use effect has effectively avoided because of the serious accident that individual personnel responsibility heart is not strong failing in time to pull up take advantage of people's platform and causes, accords with "more equipment goes up people less" safety theory completely, lets the equipment control not keep the dead angle, more can ensure the safe operation of main hoisting equipment.
