Abstract

The utility model belongs to the technical field of the single track, a single track hangs downhill path safety coefficient is related to, including the track that has the slope section the carriage that moves about on the track with hang in the driver's cabin of carriage below, be fixed with first baffle on the track and be less than the second baffle of first baffle height, be equipped with on the carriage and be used for responding to first baffle with the detection switch of second baffle position, be used for calculating the treater of downhill path speed and locating alarm device in the driver's cabin, the treater utilizes whether overspeed and pass through is judged to two induction time that the detection switch acquireed alarm device goes on speeding up and reports to the police. The utility model discloses can judge whether overspeed through the time difference of two baffles of response when the monorail crane locomotive descends to remind the driver and crew in the driver's cabin to slow down at the very first time.

Description

Monorail crane downhill safety system

Technical Field

The utility model relates to a single track system technical field, in particular to single track hangs downhill path safety coefficient.

Background

China has been introduced from abroad since the eighties of the last century and diesel locomotive monorail crane transportation systems have been developed. In recent years, with the introduction, popularization and application of foreign novel monorail crane manufacturing technology, a monorail crane auxiliary transportation system is rapidly popularized in coal mines in China.

The speed detection of the existing monorail crane is the detection of a walking wheel speed sensor, the walking wheel speed sensor is converted into a current speed value to be displayed on a display screen in a cab, and a driver controls an accelerator when going downhill so as to control the speed of the monorail crane. However, when the speed detection sensor detects abnormal conditions or the driver is distracted and the accelerator is not controlled well, the downhill speed is too high, the mechanical protection device can act, and the single-track lifting process can be stopped in an emergency manner by mistake.

Therefore, a new downhill safety system of a monorail crane is needed to improve safety.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a single track hangs downhill path safety coefficient can accurately judge whether single track loop wheel machine car exceeds speed and reminds driver and crew to slow down to suitable speed of a motor vehicle within range the very first time when the downhill path.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a single track hangs downhill path safety coefficient, including the track that has the slope section, on the track movable carriage with hang in the driver's cabin of carriage below, be fixed with first baffle and be less than on the track the second baffle of first baffle height, be equipped with on the carriage and be used for responding to first baffle with the detection switch of second baffle position, be used for calculating downhill path speed's treater and locate alarm device in the driver's cabin, the treater utilizes two induction time that detection switch acquireed judges whether to exceed the speed and pass through alarm device goes on overspeed and reports to the police.

Specifically, the alarm device is a sound alarm device.

Specifically, the processor displays the vehicle speed through a display screen arranged in the cab.

The utility model discloses technical scheme's beneficial effect is:

the utility model discloses can judge whether overspeed through the time difference of two baffles of response when single track crane vehicle downhill path to remind the driver and crew in the driver's cabin to slow down at the very first time.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

The embodiment is as follows:

as shown in fig. 1 and 2, the utility model discloses a single track hangs downhill path safety coefficient, including the track 1 that has the slope section, carriage 2 and the driver's cabin 3 of hanging in carriage 2 below of activity on track 1, be fixed with first baffle 11 and the second baffle 12 that is less than first baffle 1 height on track 1, be equipped with the detection switch 21 that is used for responding to first baffle 11 and second baffle 12 position on carriage 2, be used for calculating the treater (not drawn) of downhill path speed and locate alarm device 31 in driver's cabin 3, the treater utilizes two induction time judgments that detection switch 21 acquireed whether overspeed and carries out overspeed alarm through alarm device 31. There is a definite distance between the first apron 11 and the second apron 12, so that at a limited speed the time taken to travel this distance must be longer than a certain value. When the monorail crane passes through the first baffle plate 11 and the second baffle plate 12 successively when the monorail crane descends, the detection switch 21 senses the monorail crane and transmits signals to the processor, if the time difference between the two signals is shorter than the specific value, the fact that the average speed of the monorail crane exceeds the limit speed is indicated, and therefore the alarm device 31 can remind a driver and passengers in the cab 3 of speed reduction at the first time.

As shown in fig. 1, the alarm device 31 is an audible alarm device. The driver and passengers can be noticed more quickly and directly through the sound alarm, and the response delay is avoided.

As shown in fig. 1, the processor displays the vehicle speed through a display screen 32 provided in the cab 3. The display screen 32 can continue to display the real-time vehicle speed, allowing the driver and passengers to continue to control the vehicle speed.

What has been described above is merely some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.

Claims
