Abstract
The utility model provides a kind of gantry stone saw cutting machine, comprise column, crossbeam, be positioned at the lift slide at crossbeam two ends, lift slide is provided with for measuring the water level balance measurement mechanism of described crossbeam level, water level balance measurement mechanism forms by the horizontal liquid device and the liquid level relay that are interconnected are installed respectively, the normal contact of liquid level relay is closure or off-state, also comprise control module, control module is applicable to the duty for controlling motor disjunction, closing according to the signal sending from water level liquid level relay.This technical scheme equipment is simple, and reflection in time, avoids accident to occur.
Description
Technical field
The present invention relates to a kind of protective device of stone sawing machine, particularly relate to the balanced protection device of a kind of gantry saw.
Background technology
Gantry saw is in processing of stone industry, to be mainly used in cutting marble and granitic machinery, the mechanical wear producing during system control action, when saw rises or decline, may cause that going up and down with different paces of two gantry causes, the crossbeam that will cause like this gantry saw is uneven and cause mechanical accident; Add that processing of stone industry is all not stopped status of three-shift system 24 hours; night shift operating personnel particularly; to mental fatigue in the late into the night; if there is lifting nut and transmission fault; can not quick shutdown while causing saw frame uneven cause the expansion of mechanical breakdown, sometimes caused tens0000 plant equipment subscription rates.
Summary of the invention
For above technical problem, the invention provides a kind of discovery accident in time and can shut down rapidly, avoid the device of fault spread.
A kind of protective device of gantry stone saw cutting machine; comprise column; crossbeam; be positioned at the lift slide at crossbeam two ends; lift slide is provided with for measuring the water level balance measurement mechanism of described crossbeam level; water level balance measurement mechanism forms by the horizontal liquid device and the liquid level relay that are interconnected are installed respectively, and the normal contact of liquid level relay is closure or off-state.
Further: also comprise control module, control module is applicable to the duty for controlling motor disjunction, closing according to the signal sending from water level liquid level relay.
While there is imbalance by the lift slide when crossbeam two ends in the present invention, the water level of the A of horizontal liquid device or B end changes, when the control point of horizontal liquid device water level drops to below the bottom limit level water level of liquid level relay, water and probe disengage, the normal contact of liquid level relay is and disconnects or closure state, the liquid level relay signal that gives the alarm.So just can know rapidly crossbeam imbalance and employing measure.
This technical scheme equipment is simple, and reflection in time, avoids accident to occur.
Accompanying drawing explanation
Fig. 1 is the water level balance measurement mechanism scheme of installation of invention;
Fig. 2 is liquid level relay work schematic diagram of the present invention;
In figure, indicate: 1-column; 2-lift slide; 3-crossbeam; 4; Gantry saw; 5-liquid level relay; 6-liquid level relay.
The specific embodiment
Below in conjunction with accompanying drawing, be described further:
The protective device of the gantry stone saw cutting machine in Fig. 1; comprise column 1; crossbeam 3; be positioned at the liquid level relay lift slide 2 and gantry saw 4 that is arranged on crossbeam 3 at crossbeam 3 two ends; the lift slide 2 of the right and left is equipped with the horizontal liquid device being interconnected, and liquid level relay 5 and liquid level relay 6 are installed on horizontal liquid device.
Generally, when left and right horizon equipment balance water level is horizon equipment upper limit liquid level control point, water contacts with probe, and left and right liquid level relay detects signal to relay or PLC, and normally opened contact is closed, and machinery normally moves; When imbalance occurs horizon equipment, control point water level drops to below bottom limit level water level, and water and probe disengage, and liquid level relay detects signal to relay or PLC, and normal contact disconnects, and gives the alarm.
When relay is received alarm, to cut off the electricity supply, gantry saw is shut down.
Or PLC is while receiving alarm, instant analysis liquid level relay detects signal, sends halt instruction.
Claims (2)
1. the protective device of a gantry stone saw cutting machine; comprise the lift slide (2) that is positioned at crossbeam (3) two ends; described lift slide (2) is placed in respectively on two ends column (1); it is characterized in that; described lift slide (2) is provided with for measuring the water level balance measurement mechanism of described crossbeam (3) level
Described water level balance measurement mechanism is by being arranged on respectively the horizontal liquid device (A, B) that is interconnected and forming for detection of the water level liquid level relay of described horizon equipment (A, B), and the normal contact of described water level liquid level relay is closure or off-state.
2. protective device as claimed in claim 1, is characterized in that, described protective device further comprises: control module, described control module is applicable to the duty for controlling motor disjunction, closing according to the signal sending from described water level liquid level relay.
