Description
Technical field
The present invention relates to a kind of monorail crane driving control system, be specifically related to a kind of pneumatic monorail crane driving control system.
Background technology
In existing pneumatic monorail crane driving control system, the mode that external pneumatic monorail crane driving control system adopts reducing valve to control outer pilot control reducing valve more is controlled walking, although also can reach the object of controlling the speed of travel, but control very loaded down with trivial details, need 4 outer pilot control reducing valves, and anxious stopping do not controlled; Domestic pneumatic monorail crane driving control system directly adopts switch handle master cock amount change-over valve, control break-make and the commutation of air motor source of the gas, starting handle master cock motor speed reaches maxim at once, speed does not have progressive process, like this at monorail crane ground zero with impact while stopping very large, walk not steady, especially when starting, locomotive is popped out, and has very large potential safety hazard.
Because domestic colliery ubiquity degree of automation is lower, under ore deposit, personnel are many in addition, need operator or other people to press emergency stop switch under dangerous situation, avoid dangerous generation.
Summary of the invention
Smooth running when technical matters to be solved by this invention is to provide the pneumatic monorail crane starting of a kind of control and stops, and the pneumatic monorail crane driving control system that in case of emergency monorail crane can stopped fast.
In order to solve the problems of the technologies described above, originally the pneumatic monorail crane driving control system providing, comprise source of the gas, source of the gas main supply switch, source of the gas three linked piece, right proportional control change-over valve, right CD-ROM drive motor, left CD-ROM drive motor and left proportional control change-over valve, the air extractor duct of described right proportional control change-over valve is connected with described right CD-ROM drive motor, the air extractor duct of described left proportional control change-over valve is connected with described left CD-ROM drive motor, one end of emergency stop switch is by described source of the gas three linked piece, source of the gas main supply switch is connected with described source of the gas, the other end of described emergency stop switch respectively with handle proportional pressure-reducing valve, described right proportional control change-over valve is connected with the admission port of described left proportional control change-over valve, one of described handle proportional pressure-reducing valve control mouthful with a side of described left proportional control change-over valve and described right proportional control change-over valve and control and mouthful be connected, another of described handle proportional pressure-reducing valve controlled mouthful with the opposite side of described left proportional control change-over valve and described right proportional control change-over valve and controlled and mouthful be connected.
Described emergency stop switch is two-position three way mechanical commutation valve.
The pneumatic monorail crane driving control system that adopts technique scheme, its beneficial effect is:
1, the present invention can control the pneumatic monorail crane speed of travel, and along with the angle that handle proportional pressure-reducing valve promotes is ascending, the speed of travel of monorail crane also can be changed from small to big, and speed is controlled very steady, especially when hanging a year startup, parking, impacts little, safe and reliable.
2. the present invention has installed emergency stop switch, in case of emergency, can be by pressing emergency stop switch, and the total source of the gas of cutting system, and release the pressure in pipeline, and car is stopped rapidly, speed of response is fast, safe.
In sum, the present invention is a kind of by controlling the angle of control handle, smooth running when controlling the starting of pneumatic monorail crane and stopping, and the pneumatic monorail crane driving control system that in case of emergency monorail crane can stopped fast.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1, one end of emergency stop switch 4 is by source of the gas three linked piece 3, source of the gas main supply switch 2 is connected with source of the gas 1, the other end of emergency stop switch 4 respectively with handle proportional pressure-reducing valve 5, right proportional control change-over valve 6 is connected with the admission port of left proportional control change-over valve 9, the air extractor duct of right proportional control change-over valve 6 is connected with right CD-ROM drive motor 7, the air extractor duct of left proportional control change-over valve 9 is connected with left CD-ROM drive motor 8, control mouth and be connected with a side control mouthful of left proportional control change-over valve 9 and right proportional control change-over valve 6 simultaneously for one of handle proportional pressure-reducing valve 5, another of handle proportional pressure-reducing valve 5 controlled mouth and is connected with the opposite side control mouthful of left proportional control change-over valve 9 and right proportional control change-over valve 6 simultaneously.
Preferably, emergency stop switch 4 adopts two-position three way mechanical commutation valve.
Referring to Fig. 1, principle of work of the present invention is:
The speed of travel of pneumatic monorail crane is controlled by handle proportional pressure-reducing valve 5, along with changing from small to big of the handle angle of handle proportional pressure-reducing valve 5, the pressure of handle proportional pressure-reducing valve 5 outputs also changes from small to big, and this pressure removes to control right proportional control change-over valve 6 and left proportional control change-over valve 9.Right proportional control change-over valve 6 and left proportional control change-over valve 9 changing from small to big along with control presssure, the aperture of its spool is also changed from small to big, therefore the flow by right CD-ROM drive motor 7, left CD-ROM drive motor 8 also changes from small to big, the rotation of right CD-ROM drive motor 7, left CD-ROM drive motor 8 from slow to fast, thereby control the speed of travel.
The application of emergency stop switch 4 is actual is after source of the gas three linked piece 3, to have added a two-position three way mechanical commutation valve, under normality, the admission port of this emergency stop switch 4 is connected with the admission port of left proportional control change-over valve 9 with handle proportional pressure-reducing valve 5, right proportional control change-over valve 6, give system air feed, the source of the gas of walking is provided; When pressing the button of this emergency stop switch 4, this emergency stop switch 4 cuts off source of the gas, releases the pressure in monorail crane pipeline simultaneously, even if make monorail crane in the process of walking, also can stop at once, and speed of response is very fast, and source of the gas cuts off thorough, safe.
