Description

Technical Field

[0001] The utility model relates to the technical field of over-position protection of coal mine overhead passenger devices, in particular to a gravity inductive type over-position protection device for the head or tail of an overhead passenger machine. Background Art

[0002] At present, the overrun protection device at the tail of the overhead passenger device is to install an overrun protection limit switch near the tail of the overhead passenger device, and the installation height is close to the shoulder position of the passenger device. When the passenger has not gotten off the vehicle after reaching the alighting point, the passenger's shoulder can support the limit switch, thereby cutting off the power supply of the overhead passenger device to achieve protection.

[0003] However, in actual use, the hanging chair may swing left and right, or the passengers may intentionally not touch the mechanical rod, resulting in the inaction of the offside protection device, which can fail to provide the proper protection. The passengers may directly pass the disembarkation position and reach the tail part of the overhead passenger device, which may easily cause injury accidents. Therefore, we propose a gravity-inductive overhead passenger head or tail offside protection device. Utility Model Content

[0004] The utility model aims to provide a gravity induction type overhead passenger aircraft head or tail offside protection device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gravity inductive overhead passenger head or tail offside protection device, which relates to the technical field of offside protection of coal mine overhead passenger devices, including a rope supporting wheel, a steel wire rope, a magnetic induction wheel, a sensor and a wireless signal control box. A fixed frame fixed to the external overhead passenger device steel beam is provided on the outer side of the rope supporting wheel and the magnetic induction wheel. The rope supporting wheel and the magnetic induction wheel are both rotatably connected to the fixed frame. The rims of the rope supporting wheel and the magnetic induction wheel are both located directly below the steel wire rope. An induction gear is fixed on the outer side of the magnetic induction wheel axle. The sensor and the wireless signal control box are both fixed on the outer side of the fixed frame. A permanent magnet head is fixed on the side of the sensor close to the induction gear. The utility model transforms the offside protection device from a mechanical type to an inductive type by adopting a magnetic induction wheel, a permanent magnet head, an inductor, etc. When a passenger rides on a monkey car and enters the prohibited offside point of the head or tail of the machine, the gravity touches the induction wheel, and the induction signal gives an offside signal to the control system through the sensor and the wireless signal control box, and the control system shuts down for protection.

[0006] Preferably, the distance between the magnetic induction wheel and the steel wire rope is greater than 50 mm, so that the overhead passenger device is not prone to malfunction and stop operation during normal operation.

[0007] Preferably, the outer end of the permanent magnet head is in the shape of a sheet that is radially flush with the induction gear. A coil is provided inside the sensor that is wound around the outside of the permanent magnet head. The two ends of the coil form a cable that is electrically connected to the wireless signal control box. The sensor is more sensitive and can respond quickly to offside signals.

[0008] Preferably, two rope supporting wheels are provided, and the magnetic induction wheel is located between the two rope supporting wheels to limit the steel wire rope on the magnetic induction wheel.

[0009] Preferably, guide blocks are symmetrically arranged above the rim of the magnetic induction wheel, and the guide blocks are fixed inside the fixing frame to guide the steel wire rope to accurately fall onto the rim of the magnetic induction wheel.

[0010] Preferably, an anti-skid sleeve is fixed to the outer side of the rim of the magnetic induction wheel to prevent the wire rope from slipping on the magnetic induction wheel.

[0011] Preferably, the guide block is in the shape of a wedge that is narrow at the top and wide at the bottom, and the inner side of the lower side of the guide block is flush with the inner side of the rim of the magnetic induction wheel, so that the steel wire rope falls more smoothly.

[0012] Preferably, the sensor is of the explosion-proof type for use in mines, and the wireless signal control box is of the intrinsically safe type for use in mines, which are suitable for coal mine collection environments.

[0013] Compared with the traditional technology, the beneficial effects of the utility model are:

[0014] 1. The offside protection device is transformed from a mechanical type to an inductive type by using a magnetic induction wheel, a permanent magnet head, a sensor, etc. Under normal circumstances, when the passengers reach the normal disembarking position, the passengers get off in time. At this time, the deadweight of the hanging chair will not cause the steel wire rope to sag and touch the magnetic induction wheel, and the magnetic induction wheel will not trigger the sensor, and the overhead passenger device can continue to operate; when the passengers reach the normal disembarking position and fail to get off in time, the steel wire rope sags and presses on the magnetic induction wheel due to the gravity of the passengers, and the magnetic induction wheel rotates, and the permanent magnet head triggers the sensor, which is connected to the stop button of the wireless signal control box, and the passenger offside signal is transmitted to the overhead passenger device electronic control system, thereby realizing the offside protection function and stopping the overhead passenger device;

[0015] 2. By setting an induction gear that rotates synchronously with the magnetic induction wheel, when offside occurs, the induction gear rotates with the magnetic induction wheel. The change in the tooth shape of the induction gear causes the change in the gap between the outer side of the induction gear and the permanent magnet head, which in turn affects the magnetic flux. The induced electromotive force in the coil wound around the permanent magnet head inside the sensor changes accordingly, generating an offside current signal with high sensitivity.

[0016] 3. The magnetic induction wheel is set at a position greater than 50mm from the bottom of the wire rope, so that it is not easy to cause malfunction and stop operation during normal operation of the overhead passenger device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 The gravity induction type overhead passenger machine head or tail offside protection device shown in the figure relates to the field of offside protection technology for coal mine overhead passenger devices, including a rope supporting wheel 1, a steel wire rope 2, a magnetic induction wheel 3, a sensor 4 and a wireless signal control box 5. A fixing frame 6 fixed to the external overhead passenger device steel beam is provided on the outer side of the rope supporting wheel 1 and the magnetic induction wheel 3. The rope supporting wheel 1 and the magnetic induction wheel 3 are both rotatably connected to the fixing frame 6. The rims of the rope supporting wheel 1 and the magnetic induction wheel 3 are both located directly below the steel wire rope 2. An induction gear 7 is fixed on the outer side of the wheel axle of the magnetic induction wheel 3. The sensor 4 and the wireless signal control box 5 are both fixed on the outer side of the fixing frame 6. A permanent magnet head 8 is fixed on the side of the sensor 4 close to the induction gear 7.

[0025] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0026] See also Figure 1-Figure 4 By adopting magnetic induction wheel 3, permanent magnet head 8, sensor, etc., the offside protection device is transformed from mechanical to inductive. When passengers ride the monkey car into the prohibited offside point at the front or tail of the aircraft, the induction wheel is touched due to gravity, and the induction signal gives the control system an offside signal through the sensor 4 and the wireless signal control box 5, and the control system shuts down for protection.

[0027] Among them, the distance between the magnetic induction wheel 3 and the wire rope 2 is greater than 50 mm, so it is not easy to cause malfunction and stop operation when the overhead passenger device is operating normally. An anti-slip sleeve 10 is fixed to the outer side of the rim of the magnetic induction wheel 3 to prevent the wire rope 2 from slipping on the magnetic induction wheel 3.

[0028] Further, such as Figure 3 As shown, guide blocks 9 are symmetrically arranged above the rim of the magnetic induction wheel 3. The guide blocks 9 are fixed inside the fixing frame 6. The guide blocks 9 are wedge-shaped with a narrow upper part and a wide lower part. The inner side of the lower side of the guide block 9 is flush with the inner side of the rim of the magnetic induction wheel 3, so as to guide the steel wire rope 2 to fall accurately onto the rim of the magnetic induction wheel 3.

[0029] By adopting the magnetic induction wheel 3, the permanent magnet head 8, the sensor, etc., the offside protection device is transformed from a mechanical type to an inductive type. Under normal circumstances, when the passengers reach the normal disembarking position, the passengers get off in time. At this time, the deadweight of the hanging chair will not cause the steel wire rope 2 to sag and touch the magnetic induction wheel 3, and the magnetic induction wheel 3 will not trigger the sensor 4, and the overhead passenger device can continue to operate; when the passengers reach the normal disembarking position and fail to get off in time, the passengers ride on the hanging chair through the magnetic induction wheel 3. Due to the gravity of the passengers, the steel wire rope 2 sags and presses on the magnetic induction wheel 3, and the magnetic induction wheel 3 rotates. The permanent magnet head 8 triggers the sensor, which is connected to the stop button of the wireless signal control box 5, and the passenger offside signal is transmitted to the overhead passenger device electronic control system, thereby realizing the offside protection function and stopping the overhead passenger device.

[0030] It is worth noting that there are two rope supporting wheels 1, and the magnetic induction wheel 3 is located between the two rope supporting wheels 1 to limit the wire rope 2 on the magnetic induction wheel 3. The sensor 4 is a mine explosion-proof type, and the wireless signal control box 5 is a mine intrinsically safe type, which is suitable for coal mine collection environment.

[0031] In addition, if Figure 2 and Figure 4 As shown, the outer end of the permanent magnet head 8 is a sheet that is radially flush with the induction gear 7. A coil is arranged inside the sensor 4 and wound around the outside of the permanent magnet head 8. The two ends of the coil form a cable that is electrically connected to the wireless signal control box 5. By setting the induction gear 7 that rotates synchronously with the magnetic induction wheel 3, when offside occurs, the induction gear 7 rotates with the magnetic induction wheel 3. The change in the tooth shape of the induction gear 7 causes the change in the gap between the outside of the induction gear 7 and the permanent magnet head 8, which in turn affects the magnetic flux. The induced electromotive force in the coil wound around the permanent magnet head 8 inside the sensor changes accordingly, generating an offside current signal with high sensitivity.

[0032] After installation and use, the device has the advantages of safety, reliability and high sensitivity. It can adapt to various working conditions in the tunnel, can reliably realize offside protection, and provide safety guarantee for the efficient operation of the underground overhead passenger device. At the same time, it can prevent mechanical injury accidents caused by offside of personnel riding on the overhead passenger device, thereby ensuring life safety.
