The purpose of this utility model is to realize like this; the motor-driven strand grinding machine that has overload protection device; comprise that motor-driven strand grinding machine is connected the traction riding cable of earth anchor with motor-driven strand grinding machine; the electrically-powered actuator that it is characterized in that being provided with pulling force sensor and can receive, handle pull sensing information; pulling force sensor is arranged on the traction riding cable of motor-driven strand grinding machine; electrically-powered actuator is arranged on the motor-driven strand grinding machine, and the mouth of pulling force sensor is connected with electrically-powered actuator.
Described electrically-powered actuator is provided with pulling force demonstration, overload alarm and auto-stop control setup.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low.The technology of electronic weighing system is applied in the operation control system of motor-driven strand grinding machine; the telltale of this motor-driven strand grinding machine can quantitatively show the stressing conditions of motor-driven strand grinding rope in real time; and can auto-stop when the real work load overshoot value of motor-driven strand grinding machine; solved the technical barrier of safe construction; especially in present China extra-high voltage electric power line construction engineering, all very useful to ensureing workmen's safety, raising construction quality and construction benefit.
Description of drawings
Fig. 1 is a left side of the present utility model contour structures scheme drawing;
Fig. 2 is a right side of the present utility model contour structures scheme drawing;
Fig. 3 is an electrically-powered actuator scheme drawing of the present utility model.
Among the figure: 1 clutch belt dish, 2 disengaging of clutch pawl pull bars, 3 drag-lines, 4 strand mill clutch handles, 5 electric and hands switch handle, 6 power work indicator lamps, 7 electrically-powered actuators, 8 direct supplys, 9 telltales, 10 connect the steel rope of earth anchor, 11 sensor signal output lines, 12 pulling force sensors, 13 couplings, 14 DC machine, 15 strand mill reels, 16 drag-line reels, 17 travel switches, 18 action change-over switches, 19 wiring pile crowns, 20 relays, 21 transmission gears (motor driving gear), 22 transmission gears (drag-line reel ring gear).
The specific embodiment
The electrically-powered actuator 7 of overload protection device is installed on the body of motor-driven strand grinding machine, and electrically-powered actuator 7 is made up of direct supply 8, telltale 9, DC machine 14, drag-line reel 16, travel switch 17, relay 20, transmission gear 21,22, overload alarm and the acceptance of pull sensing information, disposal system etc.Serial connection pulling force sensor 12 (the pulling force partial message transmission of overload protection device) between the coupling 13 of motor-driven strand grinding machine and the steel rope that is connected earth anchor (traction riding cable) 10, the mouth of pulling force sensor 12 is connected to electrically-powered actuator 7.At first set a tensile load numerical value allowable at electrically-powered actuator 7 during use according to construction requirement, motor-driven then strand grinding machine is started working, during work pulling force sensor 12 with stressed size conversion become electric signal to transfer to electrically-powered actuator 7, electrically-powered actuator will carry out three work: (a) value of thrust that converts motor-driven strand grinding machine to according to the electrical information of pulling force sensor 12 transmission shows on telltale 9 in real time; (b) if real work load exceeds predefined tensile load allowable, electrically-powered actuator 7 promptly touches its internal alarm device and reports to the police; Electrically-powered actuator starts DC machine 14 and drives 16 rotations of drag-line reel through transmission gear 21,22 by relay 20 when (c) reporting to the police, pulling drag-line 3 separates the clutch belt dish 1 of motor-driven strand grinding machine, cut off the transmission of power of motor-driven strand grinding machine, strand mill reel 15 stops operating, and reaches the safety requirements that guarantees the power construction process.After clutch belt dish 1 separated, the contact on the drag-line reel 16 touched travel switch 17, and DC machine 14 stops operating thereupon.
If real work load does not reach predefined tensile load value allowable and need stop the work of motor-driven strand grinding machine the time in the work progress; still the operating sequence according to former motor-driven strand grinding machine carries out; can directly pull strand mill clutch handle 4 motor-driven strand grinding machine is quit work, this is operated overload protective device without any influence.
If do not need the function of overload protection in the work progress; can stir electric and hand switching handle 5 and touch action change-over switch 18; make motor-driven strand grinding machine be in manual state, motor-driven like this strand grinding machine is just the same with the motor-driven strand grinding machine that was unkitted overload protection device originally to be operated and has worked.
Use the motor-driven strand grinding machine that has overload protection device during construction; the stressed size of motor-driven strand grinding rope can be understood, grasp to operating personal at any time by the telltale on the electrically-powered actuator; when the real work load of motor-driven strand grinding machine exceeds predefined workload allowable; overload protection device can move the transmission of power that twists grinding machine by automatic cutting off table, reaches the purpose of safe construction.
