Abstract
The utility model provides a starter motor secondary-starting preventing circuit protective device of a diesel fork lift truck. The starter motor secondary-starting preventing circuit protective device comprises a starting relay. An input end of the starting relay is connected with a charging circuit of a generator of the diesel fork lift truck. An output control end of the starting relay is connected with a starting circuit of a starter motor. The starting relay is further connected with a neutral position relay and a key switch. The neutral position relay is connected with a gear shift handle and the key switch. A storage battery is connected with the gear shift handle, the neutral position relay and the key switch. The starter motor secondary-starting preventing circuit protective device of the diesel fork lift truck overcomes the defects in the prior art, is capable of preventing an operator from repeatedly starting the starter motor due to misoperations, and prolongs the service life of the starter motor.
Description
Technical field
The utility model relates to the anti-actuating motor reignition protective circuit device of a kind of diesel fork lift truck, belongs to the diesel fork lift truck technical field.
Background technique
At present; the protection of the anti-actuating motor reignition of the diesel fork lift truck of selling on the market mainly realizes from the key operation that resets with mechanical anti-re-lighting, and this Purely mechanical switch is after long-time the use; the switch internal mechanical partly weares and teares, and causes starting undesired.
The model utility content
The technical problems to be solved in the utility model provides and a kind ofly can prevent operator's misoperation repeated priming actuating motor, thus the anti-actuating motor reignition protective circuit device of diesel fork lift truck that prolongs the working life of actuating motor.
In order to solve the problems of the technologies described above, the technical solution of the utility model provides the anti-actuating motor reignition protective circuit device of a kind of diesel fork lift truck, it is characterized in that: comprise starting relay, the input end of starting relay is connected with the charging circuit of diesel fork lift truck generator, the output control terminal of starting relay is connected with the starting circuit of actuating motor, and starting relay also connects neutral gear relay and key operation; The neutral gear relay also connects gear handle and key operation, and storage battery connects gear handle, neutral gear relay and key operation.
When the anti-actuating motor reignition protective circuit device of a kind of diesel fork lift truck that the utility model provides uses, open the power supply shelves of key operation after, the gear handle is placed on neutral position, the neutral gear relay coil gets electric, the adhesive of neutral gear relay contact.Again key operation is got to start gear, the starting relay coil gets electric, and its contact adhesive because the starting relay common links to each other with the positive pole of battery, after the adhesive of starting relay contact, is given the coil power supply of starter motor, actuating motor work.After the motor proper functioning, key operation is returned to the power supply shelves.If again key operation is got to start gear, starting relay can't adhesive, and the starting relay coil can't be worked, and starter motor also can't proper functioning, thereby reaches the anti-reignition protection of starter motor purpose, prolongs starter motor working life.Only after motor quits work, key operation is being got to start gear, the adhesive of starter relay ability, the coil of starter motor could get electric work.
The device that the utility model provides has overcome the deficiencies in the prior art, can prevent operator's misoperation repeated priming actuating motor, has prolonged the working life of actuating motor.
Description of drawings
The anti-actuating motor reignition protective circuit device schematic representation of a kind of diesel fork lift truck that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, now with a preferred embodiment, and conjunction with figs. is described in detail below.
The anti-actuating motor reignition protective circuit device schematic representation of a kind of diesel fork lift truck that Fig. 1 provides for the utility model, the anti-actuating motor reignition protective circuit device of described a kind of diesel fork lift truck comprises starting relay, the input end of starting relay is connected with the charging circuit of diesel fork lift truck generator, the output control terminal of starting relay is connected with the starting circuit of actuating motor, and starting relay also connects neutral gear relay and key operation; The neutral gear relay also connects gear handle and key operation, and storage battery connects gear handle, neutral gear relay and key operation.
Wherein, key operation is that market is common, and model is JK411.
The working procedure of the anti-actuating motor reignition protective circuit device starting system of a kind of diesel fork lift truck that the utility model provides is: when key operation is put into start gear; the actuating motor control circuit is connected earlier; could connect the actuating motor power supply circuits; allow battery current flow into actuating motor through magnetic switch; and it is rotated, meanwhile, magnetic switch is also extrapolated with the actuation gear of actuating motor; itself and engine flywheel are meshed, drag the forwarding motivation.After treating that motor is dragged and forward to oneself to finish outburst and accelerated service; flywheel has the trend that drives the running of actuating motor actuation gear conversely, and the single clutch on the actuating motor makes the relative starter motor armature shaft idle running of the actuation gear of actuating motor (with the protection actuating motor).The operator should in time forward key operation to the power supply shelves, cuts off the actuating motor control circuit, and under the effect of control mechanism spring restoring force, actuation gear is return the original place, breaks away from and the flywheel ring gear engagement.Because power supply circuits are cut off simultaneously, actuating motor shuts down.
After opening the power supply shelves of key operation, the gear handle is placed on neutral position, and the neutral gear relay coil gets electric, the adhesive of neutral gear relay contact.Again key operation is got to start gear, the starting relay coil gets electric, and its contact adhesive because the starting relay common links to each other with the positive pole of battery, after the adhesive of starting relay contact, is given the coil power supply of starter motor, actuating motor work.After the motor proper functioning, key operation is returned to the power supply shelves.If again key operation is got to start gear; starting relay can't adhesive; because of motor when the proper functioning; generator D+ can export the high level of a 24V; its D+ is connected on the coil negative pole of starting relay; when key operation is got to start gear; the positive pole of starting relay coil has a 24V input voltage; so the pressure drop at starting relay coil two ends is 0; the starting relay coil can't be worked, and its contact can't adhesive, and starter motor also can't proper functioning; thereby reach the anti-reignition protection of actuating motor purpose, prolong actuating motor working life.Only after motor quits work, key operation is being got to start gear, the adhesive of starter relay ability, the coil of starter motor could get electric work.
