External anti-reversal starting device of single-cylinder diesel engine and use method thereof

Abstract

The invention discloses an external anti-reversal starting device of a single-cylinder diesel engine consisting of an anti-reversal starting base and a starting handle. The anti-reversal starting base comprises a connecting board, a ratchet, a claw and an automatic disengaging sleeve, wherein the ratchet is arranged on the connecting board through a bearing. The starting handle comprises a rotating sleeve, a 7-shaped handle, a starting handle and an auxiliary starting pin, wherein the diameter and an installation position of the auxiliary starting pin are matched with a groove port on the exposed end surface of a ratchet sleeve shaft. The diesel engine can be normally started only by using the handle with the auxiliary starting pin without changing the components of the diesel engine. When the diesel engine cannot be normally started and reversal generates, reverse impact force acting on the handle is transmitted to the ratchet, the invention can prevent the handle from reversely rotating and the ratchet from breaking teeth; and the handle can also automatically pop to mechanically eliminate wounding accidents caused by reversal generated when the diesel engine is started. The external anti-reversal starting device can be matched with the newly-produced diesel engine and also be used for improving the safe starting of the sold diesel engine, and has the advantages of simple structure and smaller cost increment.

Description

technical field [0001] The invention relates to a starting device for a single-cylinder diesel engine, in particular to a manual starting device with anti-reverse function. Background technique [0002] The vast majority of single-cylinder diesel engines are started by hand. The current common single-cylinder diesel engine does not have the anti-reverse function. For this reason, the country issued the first part of the mandatory standard of GB / T20064-2006 and ISO11102:1997 "Handle Device for Reciprocating Internal Combustion Engines" in 2006. "Safety Requirements and Tests" stipulates that single-cylinder diesel engines must meet the requirements of hand cranking. Safe start, and enforced on July 1, 2007, although people have thought of many technical schemes, so far, also do not have a kind of scheme that can obtain user's approval. For example, Changchai Co., Ltd. discloses an "anti-reverse rocker handle" in patent No. ZL200820040856.1. Although it can better solve the a...

[0002] The vast majority of single-cylinder diesel engines are started by hand. The current common single-cylinder diesel engine does not have the anti-reverse function. For this reason, the country issued the first part of the mandatory standard of GB / T20064-2006 and ISO11102:1997 "Handle Device for Reciprocating Internal Combustion Engines" in 2006. "Safety Requirements and Tests" stipulates that single-cylinder diesel engines must meet the requirements of hand cranking. Safe start, and it was enforced on July 1, 2007. Although people have thought of many technical solutions, so far, none of them has been approved by users.

For example, Changchai Co., Ltd. discloses an "anti-reverse rocker handle" in patent No. ZL200820040856.1. Although it can better solve the anti-reverse problem in the diesel engine starting process, its structure is very complicated and the manufacturing cost is high. , the assembly process is complicated, and at the same time, it must be used with corresponding improvements to the gear chamber cover of the diesel engine. It can only be used with newly produced diesel engines. It cannot be retrofitted with safe starting for existing diesel engines in the society, and its price increases. If the range is too large, the cost of a single unit will increase by 35 to 50 yuan, which is not only unacceptable to users, but also diesel engine manufacturers are unwilling to implement
