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...

Abstract

The invention relates to an anti-reversion device for a hand starting diesel engine, which is characterized in that the device comprises a bracket and at least a pawl assembly; a ratchet wheel lead trepan boring is provided on the bracket; the pawl assembly is arranged on the bracket around the ratchet wheel lead trepan boring and is composed of a pawl, a locating shaft, a reverse limiting shaft and a pawl return spring. The invention also discloses a starting device matched with the anti-reversion device for a hand starting diesel engine. During hand starting, a ratchet wheel lead sleeve on a starting handle can be started by smoothly passing through the pawl. When the starting handle rotates counterclockwise, the pawl which can rotate unidirectionally stops in a lead groove of the ratchet lead sleeve; the starting handle automatically slips off under the thrust of a gradually rising lead surface on the ratchet wheel lead sleeve. The device has simple and rational structure and can effectively withdraw the starting handle during starting and reversing.

Example Embodiment

[0026] Example 1. Reference figure 1. An anti-reversal device for a hand cranked diesel engine, which includes a bracket 5 and a pawl assembly. The bracket 5 is provided with a ratchet lead sleeve hole 7, and the pawl assembly is provided in the ratchet lead sleeve hole 7 On the surrounding bracket 5; the pawl assembly consists of the pawl 1, the positioning shaft 2, the reverse limit shaft 3 and the pawl return spring 6, and the front end of the pawl 1 extends to the side of the ratchet guide sleeve hole 7 , The pawl 1 is connected to the bracket 5 through the positioning shaft 2, the reverse limit shaft 3 is set on the bracket 5 behind the pawl 1, and the pawl 1 moves around the positioning shaft 2 under the action of the reverse limit shaft 3 One-way rotation; one end of the pawl return spring 6 is fixed on the bracket 5, and the other end is set on the pawl 1, and the pawl 1 returns under the action of the pawl return spring 6.

Example Embodiment

[0027] Example 2. Reference Figure 5. An anti-reversal device for a hand cranked diesel engine, which is provided with a pawl assembly. The pawl assembly is arranged on the gear chamber cover 14 around the starting shaft 11 of the diesel engine; the pawl assembly consists of a pawl 1 , Positioning shaft 2, reverse limit shaft 3 and pawl return spring 6, the front end of pawl 1 extends to the front side of starting shaft 11, pawl 1 is connected to gear chamber cover 14 through positioning shaft 2, The reverse limit shaft 3 is set on the gear chamber cover 14 behind the pawl 1. The pawl 1 rotates unidirectionally around the positioning shaft 2 under the action of the reverse limit shaft 3; the pawl return spring 6 is fixed at one end The gear chamber cover 14 is provided on the pawl 1 at the other end, and the pawl 1 returns under the action of the pawl return spring 6.

Example Embodiment

[0028] Example 3. In the anti-reversal device for a hand cranked diesel engine described in embodiment 1 or 2, the pawls are always two, which are symmetrically arranged on the left and right sides of the ratchet wheel lead sleeve hole 7.
