Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, and in particular to a safety warning device for monorail crane locomotives. Background Technology

[0002] A monorail locomotive is a highly mobile, fast-running, and heavy-duty auxiliary transportation device that travels on a suspended monorail system. It is mainly used for installation and retraction in fully mechanized coal mining faces. To improve the safety of monorail locomotive operation, existing monorail locomotives are equipped with safety warning devices that can monitor and warn personnel in the roadway in real time. The monitoring and warning mechanism obtains the distance to personnel in the roadway and transmits the distance to the controller. The controller analyzes and judges the received data and issues a warning to the monitoring and warning mechanism, promptly reminding the driver to brake.

[0003] Existing warning devices alert drivers with flashing lights and sounds. However, in single-crane locomotives, drivers may become less sensitive to sound due to fatigue, resulting in slow reaction times when braking or performing other operations. This can lead to untimely operations and safety accidents, indicating poor warning capabilities. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: existing warning devices all use flashing lights and sounds to remind the driver, but in single-rail locomotives, the driver may be less sensitive to sound due to fatigue, resulting in slow reaction when performing braking or other operations, which may lead to untimely operation and safety accidents. Therefore, this invention proposes a safety warning device for single-rail locomotives.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A monorail crane vehicle driving safety early warning device includes a vehicle body and a housing, wherein the housing is fixedly connected to the inner side wall of the vehicle body;

[0007] The housing is equipped with an adjustment mechanism, which includes a rotating rod, a turntable, an extraction cylinder, an extraction rod, and a connecting rod. The rotating rod is rotatably connected to the inner side wall of the housing, the turntable is fixedly connected to the side wall of the rotating rod, the turntable is slidably connected to the housing, the extraction cylinder is fixedly connected to the top wall of the housing, the extraction rod is slidably connected to the side wall of the extraction cylinder, and the connecting rod is hinged between the extraction rod and the turntable.

[0008] Preferably, a drive rod is rotatably connected to the inner sidewall of the housing, an amplifying gear is fixedly connected to the outer surface of the drive rod, and an arc-shaped gear ring is fixedly connected to the sidewall of the turntable, the arc-shaped gear ring meshing with the amplifying gear.

[0009] Preferably, a limiting sleeve is fixedly connected to the bottom wall of the housing, a limiting rod is slidably connected to the inner side wall of the limiting sleeve, a rack plate is fixedly connected to the upper end face of the limiting rod, a driving gear is fixedly connected to the outer surface of the driving rod, and the rack plate is meshed with the driving gear.

[0010] Preferably, an electromagnet is fixedly connected to the top wall of the housing, and a magnetic plate is fixedly connected to the lower end face of the electromagnet.

[0011] Preferably, an extraction plate is fixedly connected to the side wall of the extraction rod, the extraction plate is slidably connected to the inner side wall of the extraction cylinder, a water storage tank is fixedly connected to the upper end face of the housing, and a spray head is fixedly connected to the side wall of the turntable.

[0012] Preferably, an inlet pipe is fixedly connected between the extraction cylinder and the water storage tank, and an outlet pipe is fixedly connected between the extraction cylinder and the nozzle. Both the inlet pipe and the outlet pipe are equipped with one-way valves, and a return spring is fixedly connected between the rack plate and the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the coordination of electromagnets, amplifying gears, turntables, and other structures, when an emergency occurs, the alarm system emits flashing lights and alarm sounds, simultaneously driving the extraction cylinder to spray water and causing the nozzle to rotate. This sprays water onto the faces of drivers of different heights and positions, instantly stimulating the sympathetic nervous system, temporarily dispelling drowsiness, and enabling the driver to react quickly and brake in time. This prevents the driver from becoming sluggish due to fatigue and slowed reaction to the alarm, thus avoiding potential dangers. Attached Figure Description

[0022] Reference Figures 1-4 A monorail crane travel safety warning device includes a car body 1 and a housing 2. The housing 2 is sealed to protect the internal components from dust and other contaminants, and also facilitates lubrication. The housing 2 is fixedly connected to the inner wall of the car body 1. An adjustment mechanism is provided inside the housing 2. The adjustment mechanism includes a rotating rod 3, a turntable 4, an extraction cylinder 5, an extraction rod 6, and a connecting rod 7. The rotating rod 3 is rotatably connected to the inner wall of the housing 2. The turntable 4 is fixedly connected to the side wall of the rotating rod 3. An installation groove is provided on the housing 2. The turntable 4 is slidably connected in the installation groove. The turntable 4 and the housing 2 are sealed and slidably connected. The extraction cylinder 5 is fixedly connected to the top wall of the housing 2. The extraction rod 6 is slidably connected to the side wall of the extraction cylinder 5. The extraction rod 6 and the extraction cylinder 5 are not sealed. An extraction plate 16 is fixedly connected to the side wall of the extraction rod 6. The extraction plate 16 is sealed and slidably connected to the inner wall of the extraction cylinder 5. The connecting rod 7 is hinged between the extraction rod 6 and the turntable 4.

[0023] Reference Figure 4 A drive rod 8 is rotatably connected to the inner wall of the housing 2, and an amplifying gear 9 is fixedly connected to the outer surface of the drive rod 8. An arc-shaped gear ring 10 is fixedly connected to the side wall of the turntable 4, and the arc-shaped gear ring 10 meshes with the amplifying gear 9.

[0024] Reference Figure 4A limiting sleeve 11 is fixedly connected to the bottom wall of the housing 2. A limiting rod is slidably connected to the inner side wall of the limiting sleeve 11. The limiting sleeve 11 limits the limiting rod and the rack plate 12. The limiting rod can only slide and cannot rotate, ensuring that the rack plate 12 and the drive gear 13 are stably meshed. The rack plate 12 is fixedly connected to the upper end face of the limiting rod. The drive gear 13 is fixedly connected to the outer surface of the drive rod 8. The rack plate 12 and the drive gear 13 are meshed and connected.

[0025] Reference Figure 4 An electromagnet 14 is fixedly connected to the top wall of the housing 2. The electromagnet 14 is connected to the power supply of the existing alarm device. When the existing alarm device is in danger and the buzzer or warning light is powered on synchronously, the electromagnet 14 is also powered on synchronously. A magnetic plate 15 is fixedly connected to the lower end face of the electromagnet 14. The magnetic plate 15 is a permanent magnet with strong magnetic force and good corrosion resistance.

[0026] Reference Figure 2 and Figure 4 A water tank 17 is fixedly connected to the upper end face of the housing 2. The water tank 17 stores clean water. A nozzle 18 is fixedly connected to the side wall of the turntable 4. The nozzle 18 is directly facing the driver's head. An inlet pipe 19 is fixedly connected between the extraction cylinder 5 and the water tank 17. An outlet pipe 20 is fixedly connected between the extraction cylinder 5 and the nozzle 18. Both the inlet pipe 19 and the outlet pipe 20 are equipped with one-way valves. The flow direction of the one-way valve in the inlet pipe 19 is from the water tank 17 to the extraction cylinder 5. The flow direction of the one-way valve in the outlet pipe 20 is from the extraction cylinder 5 to the nozzle 18. A return spring 21 is fixedly connected between the rack plate 12 and the housing 2.

[0027] In this invention, when an emergency occurs, the alarm device powers on the buzzer to sound an alarm and simultaneously powers on the electromagnet 14, repelling the magnetic plate 15. The magnetic plate 15 then moves the rack plate 12 downwards, causing the limit rod to move up and down within the limit sleeve 11 and compressing the return spring 21. The rack plate 12 then drives the drive gear 13 to rotate clockwise, which in turn drives the drive rod 8 and the amplifying gear 9 to rotate. The diameter of the amplifying gear 9 is higher than that of the drive gear 13, thus amplifying the movement distance of the magnetic plate 15. The amplifying gear 9 also drives the arc-shaped gear ring 10 to rotate the turntable 4. When the turntable 4 rotates counterclockwise, the turntable 4 drives the extraction rod 6 to move upward through the connecting rod 7, squeezing the extraction plate 16. The one-way valve in the water inlet pipe 19 closes, and the one-way valve in the water outlet pipe 20 opens. The clean water in the extraction cylinder 5 enters the nozzle 18 through the water outlet pipe 20, so that the nozzle 18 sprays onto the driver's face. The turntable 4 drives the nozzle 18 to rotate at a certain angle, so that it can spray onto the face of drivers of different heights. The clean water stimulates the sympathetic nerves upon contact with the skin, temporarily dispelling drowsiness and enabling the driver to react quickly and brake in time, avoiding the driver's slow reaction to the alarm sound due to fatigue, which could lead to danger.

[0028] When the alarm disappears after braking, the warning system de-energizes the buzzer and electromagnet 14, and the repulsive force of electromagnet 14 on magnetic plate 15 disappears. Under the elastic force of return spring 21, rack plate 12 drives drive gear 13 to reset, drive gear 13 drives drive rod 8 and amplifying gear 9 to reset, amplifying gear 9 drives arc gear ring 10 to reset turntable 4, turntable 4 rotates clockwise, turntable 4 drives extraction rod 6 to move down through connecting rod 7, stretching extraction plate 16, one-way valve in water inlet pipe 19 opens, one-way valve in water outlet pipe 20 closes, and clean water in water storage tank 17 enters extraction cylinder 5 through water inlet pipe 19.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
