Problems solved by technology

Although there are many types of anti-sports car devices at present, there are various safety hazards in the existing anti-sports car devices to varying degrees, resulting in frequent accidents of sports cars that are difficult to control, seriously restricting the transportation efficiency of rail transportation, and affecting the personal safety of underground workers. serious impact on safety
[0003] At present, almost all mine inclined roadway rail transportation adopts "one slope, three gears" anti-car device, which can only passively prevent sports car accidents, but cannot completely eliminate sports car accidents, and is safe and reliable Sex is not enough

Embodiment 1

[0048] like Figures 1 to 5 As shown in the figure, the automatic anti-running mine car of the inclined lane according to the present invention includes a mine car body, which can run along the inclined lane guide rail through the wheels, and an anti-running mine car is arranged between the mine car body and the inclined lane guide rail. Clutch mechanism; the anti-running clutch mechanism includes a speed limit sensing device, an anti-running catch device and a car blocker; it can be seen that the braking car can immediately drive to the anti-running catch device at the moment when a sports car trend appears The mechanism sends a trigger signal to realize the immediacy of the braking and parking of the anti-running and arresting device, prevent the occurrence of accidents, and avoid personnel accidents and property losses.

[0049] The speed limit sensing device can sense the wheel speed, and when the wheel speed reaches the preset limit speed, can send a trigger signal to the...

Embodiment 2

[0061] The difference between this embodiment and Embodiment 1 is that different structural forms of drive mechanisms, speed limit sensing devices, and different arrangements of vehicle arresters are used. The rest of the components are of the same structural form as Embodiment 1. Repeat. Only the differences mentioned above will be elaborated as follows:

[0062] like Figure 6-9 As shown, in this embodiment, the drive mechanism is a hydraulic drive system, including an oil tank, an oil cylinder and a hydraulic system oil circuit; the speed limit sensing device includes a valve trigger and a sprocket transmission mechanism.

[0063] The sprocket transmission mechanism includes a driving sprocket, a driven sprocket, and a chain that goes around the driving sprocket and the driven sprocket; the driving sprocket is fixed on the rotating shaft of the wheel, and the power input of the driven sprocket and the valve trigger End connection; according to the actual operating conditi...

Abstract

The invention discloses an automatic anti-running mine car for inclined lanes and an anti-running braking method thereof. The inclined lane automatic anti-running mine car includes a mine car body, which can run along the inclined lane guide rail through the wheels; an anti-running clutch mechanism is arranged between the mine car body and the inclined lane guide rail; the anti-running clutch mechanism includes a speed limit sensing device , anti-running and arresting device and car arrester; the speed limit sensing device can sense the wheel speed, and when the wheel speed reaches the preset limit speed, it can send a trigger signal to the driving mechanism of the anti-running and arresting device; The catching device includes a catching component, a driving mechanism and a braking winch. The driving mechanism and the braking winch are fixedly installed on the mine car body; The active protection of alley transport vehicles can eliminate the occurrence of sports car accidents from the root cause and improve the safety of inclined alley transport.

Description

technical field [0001] The invention relates to an automatic anti-running mine car in inclined lanes and an anti-running braking method thereof, belonging to the field of underground inclined lane transportation in coal mines. Background technique [0002] In coal mine production, mine transportation accidents occur from time to time, and the inclined lane sports car is one of the frequent accidents, which has become one of the "five disasters" that threaten the safety of coal mine production. As an important device to prevent sports car accidents, the safety and reliability of the anti-sports car device in the inclined lane has always been the focus of research. Although there are many types of anti-sports car devices at present, all existing anti-sports car devices have various safety hazards to varying degrees, resulting in frequent occurrence of uncontrollable sports car accidents, seriously restricting the transportation efficiency of rail transportation, and affecting ...
