The utility model has the benefits of low cost, long service cycle, convenience in installation and maintenance as well as high sensitivity, and is safe, reliable, convenient and applicable.
Description
Technical field
The utility model relates to a kind of stop, specifically is a kind of vibration induction formula stop, belongs to Safety for mine car control technology field.
Background technology
At present; the orbit mine car that use in the down-hole in most of collieries; the mechanical type stops that adopt more; its sensitivity is relatively poor; maloperation often appears; safety factor is low; damage easily in subsurface environment, operating cycles is short, the installation and maintenance inconvenience of getting up; therefore; mine car speed of a motor vehicle hypervelocity and the out-of-control phenomenon that produces brought great hidden danger to safety of life and property, and conventional stop cost is higher in use appears through regular meeting; expend a large amount of manpower and materials, be difficult to be applicable to modernized Coal Production activity.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of vibration induction formula stop, can control the mine car gait of march timely and effectively, avoids the generation of mine car out-of-control phenomenon, has reduced accident potential.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of vibration induction formula stop, comprise acceleration sensor module, micro controller system acceleration pick-up, acceleration/accel vibration induction module, pulley, hauling hook, mine car, support and track, acceleration sensor module is made of micro controller system acceleration pick-up and acceleration/accel vibration induction module; Micro controller system acceleration pick-up, pulley and support are installed in the top, tunnel, acceleration/accel vibration induction module correspondence is installed in the both sides of track, hauling hook is installed on the hauling rope of pulley lower end respectively and on the bottom end positions of mine car, acceleration sensor module electrically connects by micro controller system acceleration pick-up and pulley, and the micro controller system acceleration pick-up is connected by analogous circuit with acceleration/accel vibration induction module.
The invention has the beneficial effects as follows: cost is low, and operating cycles is long, makes things convenient for installation and maintenance, and is highly sensitive, safe and reliable, convenient being suitable for.

Among the figure: 1, acceleration pick-up, 2, the micro controller system acceleration pick-up, 3, acceleration/accel vibration induction module, 4, pulley, 5, hauling hook, 6, mine car, 7, support, 8, track.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As depicted in figs. 1 and 2, a kind of vibration induction formula stop, comprise acceleration sensor module 1, micro controller system acceleration pick-up 2, acceleration/accel vibration induction module 3, pulley 4, hauling hook 5, mine car 6, support 7 and track 8, acceleration sensor module 1 is made of micro controller system acceleration pick-up 2 and acceleration/accel vibration induction module 3; Micro controller system acceleration pick-up 2, pulley 4 and support 7 are installed in the top, tunnel, acceleration/accel vibration induction module 3 correspondences are installed in the both sides of track 8, hauling hook 5 is installed on the hauling rope of pulley 4 lower ends respectively and on the bottom end positions of mine car 6, acceleration sensor module 1 electrically connects by micro controller system acceleration pick-up 2 and pulley 4, and micro controller system acceleration pick-up 2 and acceleration/accel vibration induction module 3 are connected by analogous circuit.
As shown in Figure 3, the circuit theory scheme drawing of the micro controller system acceleration pick-up 2 in the acceleration sensor module 1, singlechip chip wherein can adopt the MMA122OD type.
Before the use, degree of will speed up sensor assembly 1, pulley 4 and support 7 are installed in the place apart from driving surface 80m to 100m, and the value of testing the speed that acceleration/accel vibration induction module 3 is provided with acquiescence is 0.5m/s
2When mine car 6 marches to acceleration/accel vibration induction module 3 places, trigger the 3 startup work of acceleration/accel vibration induction module, in advancing, vibrate the pressure size that produces by sensing mine car 6 and come the sensing mine car instantaneous acceleration of 6 this moments, and send the instantaneous acceleration signal of mine car 6 this moment to micro controller system acceleration pick-up 2, if micro controller system acceleration pick-up 2 determines the instantaneous acceleration of mine car 6 of this moment greater than the acquiescence value of testing the speed 0.5m/s
2Then micro controller system acceleration pick-up 2 will send control command to pulley 4, start pulley 4 and put down hauling rope, make top that hauling hook 5 on the hauling rope quickly falls to track 8 catching the hauling hook 5 on the mine car 6, thereby the speed of controlling mine car 6 drops to below the safety speed.
