Diesel engine hand-operated actuating inversion proof device and matched start-up device

Abstract

The invention relates to a hand starting anti-reversion device of a diesel engine, which is characterized in that the device comprises at least a pawl assembly installed around the front side of a starting shaft of the diesel engine; the pawl assembly is installed on the diesel engine directly or by a rack and consists of a pawl, a locating shaft, a reverse limit bolt and a pawl return spring. The invention also relates to a starting device mating the anti-reversion device; when starting, a ratchet lead sleeve assembly or a ratchet block sleeve assembly on a starting handle can smoothly startvia the pawl; when the starting handle contrarotates, the pawl stops between ratchet teeth of the ratchet lead sleeve assembly or a ratchet block sleeve assembly and the starting handle automaticallyslides out under the mutual action of the ratchet lead sleeve assembly or a ratchet block sleeve assembly and an exiting lead groove or an exiting block. The anti-reversion device has simple and reasonable structure and can effectively facilitate the starting handle to withdraw during starting and reversion, thus completely avoiding the occurrences of accidents of hurting people due to starting and reversion.

Description

technical field [0001] The invention relates to an accessory of a diesel engine, in particular to a hand crank anti-reversal device for a diesel engine; the invention also relates to a hand crank start device for a diesel engine matched therewith. Background technique [0002] Most of the single-cylinder diesel engines currently in use still start by manpower. When the temperature drops, the physical strength of the operator is insufficient, repeated starts are unsuccessful, the diesel engine fails, or the engine is loosened and depressurized before reaching a certain speed when starting, etc., it will cause the diesel engine to reverse and the starting handle (cradle) will follow the reverse direction. In turn, it is impossible to withdraw voluntarily, resulting in the occurrence of injury accidents.

AI Technical Summary

Problems solved by technology

When the temperature drops, the physical strength of the operator is insufficient, repeated starts are unsuccessful, the diesel engine fails, or the engine is loosened and depressurized before reaching a certain speed when starting, etc., it will cause the diesel engine to reverse and the starting handle (cradle) will follow the reverse direction. In turn, it is unable to withdraw by itself, which leads to the occurrence of injury accidents.

[0003] In addition, due to poor starting skills or negligence of the starter, such as not holding the starter handle tightly, standing too far away from the engine, or unable to rotate the diesel engine at a constant speed when starting, etc., it is easy to cause the starter handle to be thrown out and hurt the face of the starter. part, especially the starting handle of the extended rocker arm is more dangerous

[0004] Many unsafe factors mentioned above will cause diesel engine starting accidents, which seriously threaten the life safety of starting personnel.

Existing hand crank diesel engines cannot meet the relevant national hand start industry standards
