Problems solved by technology

[0002] When the driver is driving the vehicle, he often forgets to release the hand brake, which will cause the vehicle to drive with the hand brake, causing the brake system to wear out and fail, and even cause a fire due to overheating
At present, there are mainly two parking protection methods on the market: one is to only alarm without cutting off the power, which will still cause damage to the braking system; the other is to directly cut off the power without considering the working environment, which will cause Safety hazards such as slippery slopes when forklifts work on slopes

Abstract

The invention discloses a diesel fork lift truck parking safety control method. The method includes the following steps that the maximum parking gradient W with a power maintaining requirement is setfor a controller U; when a parking control module is in a parking state and a gear switching module is in an advancing / retracting state, the controller U compares the gradient v, detected by an anglesensor G1, of a diesel fork lift truck with the set value W, if v is smaller than W, the controller U controls a power maintaining relay K8 not to work, power output is cut off, and the controller U controls a delayed alarm device to work; and if v is larger than W, the controller U controls the power maintaining relay K8 to work, power output is not cut off, and the controller U controls the delayed alarm device to work. The method has the following beneficial effects that abrasion of a brake system can be reduced, and the service life of the brake system is prolonged; and meanwhile a slip condition can be reduced, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of parking safety control, in particular to a parking safety control method for an internal combustion forklift that can reduce the wear of the brake system, prolong the service life of the brake system and improve safety. Background technique [0002] When the driver is driving the vehicle, he often forgets to release the hand brake, which causes the vehicle to drive with the hand brake, causing the brake system to wear out and fail, and even cause a fire due to overheating. At present, there are mainly two parking protection methods on the market: one is to only alarm without cutting off the power, which will still cause damage to the braking system; the other is to directly cut off the power without considering the working environment, which will cause When forklifts work on slopes, there are safety hazards such as sliding slopes. Contents of the invention [0003] In order to overcome the serious wear...
