Abstract
A diesel engine oil supply and cut-off control device is characterized in that a threaded transmission pair consisting of a motor driving gear reducer and a threaded pull rod through a threaded shaft sleeve controls the threaded pull rod to move left and right axially, one end of the threaded pull rod drives a stroke control slide plate to control a bidirectional stroke switch, the other end of the threaded pull rod is connected with an engine through a steel wire rope, and when the device works, the engine is controlled to start and stop in a positioning mode.
Description
The utility model be the diesel engine used on steam supply car or the tractor by turn to use when shutting down for the oil-break control gear
According to the retrieval, present and the intimate diesel engine for automobile of the utility model is called " diesel engine for automobile shorting-out device " for its name of oil-break control gear, the patent No. is 93237548.0, it is by motor, worm speed reducer, crank, and connecting rod, reducing sleeve, stay cord, pull bar, position limit switch and base plate are formed.Worm speed reducer, reducing sleeve and position limit switch are contained on the base plate respectively, motor and worm speed reducer link, crank is installed on the worm-wheel shaft of worm speed reducer, one end of connecting rod and the lower end of crank link, the other end and pull bar link, one end and the pull bar of stay cord link, and the other end and diesel engine decompressor handle link
Its working principle is: after the high speed rotating of motor obtains very big deceleration by worm speed reducer, again by connecting rod be transformed into the low-speed rectilinear movement of pull bar, the reciprocating stroke of pull bar is controlled by two position limit switches.Control the oil-break that supplies of motor by the stay cord that links to each other with pull bar.Obviously, its complex structure is made difficulty, the cost height, and efficient is low, and precision is low, and the life-span is short, and motor load is heavy easily to be burnt, and is difficult to continuous 50,000 times requirement working life.
The purpose of this utility model provides a kind of diesel engine for the oil-break control gear, and this apparatus structure is simply compact, easily manufactured, with low cost, and work is more reliable and more stable, long service life.
Technological scheme for the oil-break control gear comprises: be fixed in the fixed plate on the shell frame, and the circuit fixed plate, wherein: relay and position limit switch, Stroke Control slide plate all are arranged on the circuit fixed plate; The input end and the machine shaft of gear reducer connect, the output shaft of gear reducer is threaded sleeve and is assemblied on the fixed plate through bearing, thread and threaded sleeve are formed the screw thread transmission and are paid, one end of thread drives Stroke Control slide plate control two-way travel switch, the other end stretches to the shell frame outside, and is connected with the decompressor handle bar of motor through steel wire tow line
The described retarder of said apparatus is made up of a pair of gear engagement of size
Axis that screw thread transmission in the said apparatus is paid and machine shaft line parallel
Relay in the said apparatus is a double-contact relay.
The utility model has the advantages that: by moving axially about motor-driven gear reducer control thread, one end of thread drives Stroke Control slide plate control two-way travel switch, the other end is connected with motor through wire rope, and during work, the positioning control engine start is shut down; This device implementation structure compactness, easily manufactured, working stability is reliable, can reach continuous operation working life more than 60,000 times.
Further describe the utility model below in conjunction with example.
Fig. 1 is a structure diagram of the present utility model
Among the figure in shell frame base plate 17 sides, vertical fixing is provided with a circuit fixed plate 3 along its length, be bonded with Stroke Control slide plate 14 in the upper end of circuit fixed plate 3, length direction at Stroke Control slide plate 14 is processed with the long groove of a waist shape, and the length direction two ends of groove respectively are provided with a two-way microswitch 6; Be installed with a double-contact relay 4 on the lower end surface of circuit fixed plate 3, this relay also can be two of single contacts and is arranged side by side, and double-contact relay 4 also can be fixed on the shell frame.Gear reducer 15 is made up of a pair of gear engagement of size; 24V direct current generator 1 is fixed on the fixed plate 8, and the small gear 10 on the rotating shaft of motor 1 and the gear reducer 15 connects; The output shaft 16 of gear reducer 15 is assemblied on the fixed plate 8 for threaded sleeve and through rolling bearing, and thread 5 is paid with the transmission of threaded sleeve composition screw thread, and thread 5 profiles are an end buckle head, and gib head end cover fits in the gain of Stroke Control slide plate 14; Its other end stretches to shell frame 17 outsides and is connected with handle bar on the motor decompressor through steel wire tow line 13 and connecting sleeve 12
The operating voltage of motor is the 24V direct current.The power supply of whole device links to each other with switch and power supply by DJ7041-6.3-20 four hole connector assemblys.By technique scheme, can use onboard after making and installing.
Below in conjunction with the actual use condition of this used for diesel engine of description of drawings for the oil-break control gear.Be in the state of straining the diesel engine decompression handle at diesel engine outage state steel wire tow line 13, the diesel engine oil feed pump is in the oil-break position.When the forward rotation switch, the power supply of device is switched on, motor 1 forward rotation, at this moment small gear 10 drives that are contained on the machine shaft are contained in the rotation that the gearwheel 9 on the main fixed plate 8 is done than low speed, thereby the thread 5 that is contained in the gearwheel axle sleeve is moved to the right as straight line, when thread 5 moves to certain position, to drive the Stroke Control slide plate presses two-directional micromotion switch 6 and cuts off the electricity supply, motor 1 stops operating, at this moment steel wire tow line 13 is in relaxation state, and the diesel engine oil feed pump is in for not having the position.Beginning to turn to the whole process that stops operating from motor 1 lasted less than 1 second.When the needs diesel engine is shut down; can oppositely change switch; this moment device the circuit both positive and negative polarity and above-mentioned oppositely and and power connection; the motor backward rotation when thread is moved to the left to certain position, will drives the Stroke Control slide plate and break away from two-directional micromotion switch 6; cut off the electricity supply; motor 1 stops operating, and the wire rope of tension quits work and oil-break the oil feed pump of diesel engine, and diesel engine is shut down and to be begun to be inverted to the process of haveing suffered that stops operating from motor 1 and last equally less than 1 second.
