The description includes the following figures, the contents shown are respectively:
fig. 1 is a schematic structural diagram of a forklift braking system of the present invention;
labeled as: 1. an air inlet pipe; 2. an air compressor; 3. a first connecting pipe; 4. an oil-water separator combination valve; 5. an air cylinder; 6. a pressure alarm; 7. a safety valve; 8. a water drain valve; 9. an air brake valve; 10. a booster pump; 11. a three-way joint; 12. and a sixth connecting pipe.
Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.
As shown in fig. 1, the utility model provides a fork truck braking system, including the stopper, intake pipe 1 with engine air intake system is connected, air compressor machine 2 with intake pipe 1 is connected, the oil water separator combination valve 4 is connected with air compressor machine 2, the gas receiver 5 of being connected with oil water separator combination valve 4, the air brake valve 9 of being connected with gas receiver 5 and the thrust augmentation pump 10 of being connected just with the stopper with air brake valve 9.
Specifically, as shown in fig. 1, one end of an air inlet pipe 1 is connected with an engine air inlet system, the other end of the air inlet pipe 1 is connected with an air inlet of an air compressor 2, the engine air inlet system filters air, the filtered air enters the air compressor 2 through the air inlet pipe 1, an air outlet of the air compressor 2 is connected with an air inlet of an oil-water separator combination valve 4 through a first connecting pipe 3, the air compressor 2 is connected with the engine air inlet system, and the air quality entering a brake system can be guaranteed. The oil-water separator combination valve 4 is used for removing impurities, moisture and the like in air, an air outlet of the oil-water separator combination valve 4 is connected with an air inlet of the air storage cylinder 5 through a second connecting pipe, an air outlet of the air storage cylinder 5 is connected with an air inlet of the air brake valve 9 through a third connecting pipe, and the air storage cylinder 5 is used for storing compressed air. An air outlet of the air brake valve 9 is connected with a booster pump 10 through a fourth connecting pipe, the air brake valve 9 is used for being trampled by a forklift driver, brake fluid is filled in the booster pump 10, and the booster pump 10 is used for supplying the brake fluid to a brake.
Preferably, as shown in fig. 1, the air cylinder 5 is provided with a pressure alarm 6, a safety valve 7 and a water discharge valve 8. Through integrated relief valve 7 and pressure alarm 6 on the gas receiver 5, pressure alarm 6 can report to the police when 5 internal pressure of gas receivers is less than the setting value, guarantees fork truck security of traveling.
As shown in fig. 1, the brakes are connected to a booster pump 10 through a three-way joint 11, and two brakes are provided. The booster pump 10 is connected with one interface of the three-way joint 11 through a fifth connecting pipe, the other two interfaces of the three-way joint 11 are respectively connected with two brakes through two sixth connecting pipes 12, and the brakes are caliper disc brakes. When braking, after the air brake valve 9 is stepped on, the brake fluid in the booster pump 10 is respectively conveyed to the left brake caliper and the right brake caliper through the three-way joint 11 and the sixth connecting pipe 12, and braking is achieved.
The utility model also provides a fork truck, fork truck braking system including above-mentioned structure. The specific structure of the forklift braking system can be referred to fig. 1, and details are not repeated here. Because the utility model discloses a fork truck includes the fork truck braking system in the above-mentioned embodiment, so it has above-mentioned fork truck braking system's all advantages.
