[0002] Coal mine underground roadways are narrow, dusty, noisy, and dimly lit. In addition, most of the vehicles used in underground coal mines have large dimensions, and the driver has a large blind spot when the vehicle starts and drives. Therefore, vehicles often start and drive in coal mines. security incident
In particular, the driver is negligent in checking and warning before starting the vehicle. Impatient driving may easily cause casualties to people around the vehicle, which seriously affects the safety of mining vehicles during the starting process.

Embodiment Construction
[0013] A start-up delay alarm device for underground mining vehicles in coal mines, including a travel variable pump for starting the driving of coal mine underground mining vehicles and a pilot oil circuit for controlling the displacement of the travel variable pump. The pilot oil circuit is provided with a parking device The pressure oil inlet and the oil outlet connected to the pilot control oil of the walking variable pump, on the pilot oil circuit between the oil outlet and the pressure oil inlet, a hydraulic control reversing valve 3, a sequence valve 6 and an adjustable flow control valve are installed in sequence. Valve 12 is connected with a pressure oil branch at the pressure oil outlet of the sequence valve 6 4. A pressure oil branch is connected to the pressure oil inlet of the adjustable throttle valve 12 10. Pressure oil branch 10 and pressure oil branch There is a time-delay sound and light alarm device between 4, and the time-delay sound and light alarm d...

Disclosed is a start delay warning device for a coal mine down-hole mine vehicle. The start delay warning device comprises a pilot oil circuit. The pilot oil circuit is provided with a pressure oil inlet and an oil outlet. A hydraulic operated directional valve, a sequence valve and an adjustable restrictive valve are installed on the pilot oil circuit between the oil outlet and the pressure oil inlet sequentially. A pressure oil inlet of the sequence valve is connected with a pressure oil branch I. A pressure oil inlet of the adjustable restrictive valve is connected with a pressure oil branch II. A delay sound-light warning device is arranged between the pressure oil branch I and the pressure oil branch II. The part, between the sequence valve and the adjustable restrictive valve, of the pilot oil circuit is provided with an energy accumulator. The start delay warning device can be applied to all coal mine down-hole hydraulic drive vehicles. The delay sound-light warning device is integrated into a vehicle braking system and a hydraulic pilot system, so that the vehicles are forced to conduct sound-light warning automatically before starting and be started in delay. The accidents of casualties surrounding the vehicles due to impatience driving can be effectively avoided, and the safety of the coal mine down-hole mine vehicle is greatly improved.
Description
technical field [0001] The invention relates to a coal mine underground vehicle alarm device, in particular to a coal mine underground mining vehicle startup delay alarm device. Background technique [0002] Coal mine underground roadways are narrow, dusty, noisy, and dimly lit. In addition, most of the vehicles used in underground coal mines have large dimensions, and the driver has a large blind spot when the vehicle starts and drives. Therefore, vehicles often start and drive in coal mines. There is a security incident. Especially the driver is negligent in checking and warning before starting the vehicle. Impatient driving can easily cause casualties to people around the vehicle, which seriously affects the safety of the mining vehicle during the starting process. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a start-up delay alarm device for coal mine underground mining vehicles that avoids driving accide...
