Problems solved by technology

The existing empty container stacker adopts a full-hydraulic braking system, which simply meets the braking requirements, without too much consideration for braking performance and braking safety, and there are certain problems. During use, there are mainly the following: Disadvantages: 1. The temperature of the brake oil is too high, and the brake system and the vehicle hydraulic system share the same oil tank. The brake system can only use hydraulic oil to work, and cannot use special brake fluid, causing the vehicle to drive when braking. There are abnormal noises in the bridge; 2. There are few safety protection measures in the braking system; 3. The brake system is affected by the abrasive particles of the brake friction plate, so that the service life of the braking components in the system is short

Abstract

The invention relates to a brake system of an empty container forklift. The brake system of the empty container forklift comprises a braking oil tank, a gear pump, a prefill valve, a reducing valve, a two-position three-way electromagnetic valve, a gearbox clutch, a first bag type accumulator, a right-foot brake valve, a left-foot brake valve, a shuttle valve, and a stopping brake valve block. A brake oil radiator, the brake oil tank, an overflow valve, a second bag type accumulator and a backpressure valve are additionally arranged in the system. Through adding of the brake oil radiator, the temperature of the whole brake system is effective controlled to be around 60 DEG C, and therefore a sealing part of the whole brake system is well protected. Through adding of the brake oil tank, hydraulic oil which is not suitable for brake friction is not applied to the brake system, and heavy-load wet-type axle brake liquid which is specially prepared is used, so that howling generated by a friction piece and a partition piece in a drive axle is reduced in the process of brake, the whole vehicle brake distance is shortened, and reliability of the whole brake system is improved.

Description

technical field [0001] The invention belongs to the technical field of stackers for empty containers, and in particular relates to a brake system for stackers for empty containers. Background technique [0002] Empty container stacker is the necessary empty container stacking equipment for various ports, cargo stations and container production enterprises. It has high operating efficiency and frequent work. The existing empty container stacker adopts a full hydraulic braking system, which simply meets the braking requirements, without too much consideration for braking performance and braking safety, and there are certain problems. During use, there are mainly the following: Disadvantages: 1. The temperature of the brake oil is too high, and the brake system and the vehicle hydraulic system share the same oil tank. The brake system can only use hydraulic oil to work, and cannot use special brake fluid, causing the vehicle to drive when braking. There are abnormal noises in...
