Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, for a kind of dumping car hydraulic lifting control system, comprise fluid power system, hydraulic lifting system and control cock group, described fluid power system comprises the hydraulic circuit and hydraulic-driven path that are made up of hydraulic reservoir 1, engine installation 2, control cock group and oil pipe component, and described hydraulic-driven path connects hydraulic lifting system 6 by high pressure fuel pipe 11; Described hydraulic-driven path is connected in parallel to closed-centre system, and described closed-centre system comprises the energy storage canister 12 for storing high pressure liquid force feed; In wherein said fluid power system, hydraulic reservoir 1 is by the input end of oil pipe 8 connecting power device 2, the mouth of described engine installation 2 connects hydraulic reservoir 1 by loop oil pipe 9, composition hydraulic circuit, is provided with automatic controlling valve 3 between described engine installation 2 mouth and hydraulic reservoir 1; Connecting path oil pipe 10 on the another one output port of automatic controlling valve 3, described path oil pipe 10 connects hoist control valve 5, forms hydraulic-driven path.
Described energy storage canister 12 is arranged in parallel on the path oil pipe 10 in hydraulic-driven path between automatic controlling valve 3 and hoist control valve 5, described path oil pipe 10 is provided with switching control pilot 7, and described switching control pilot 7 is between energy storage canister 12 and two coupling ends of path oil pipe 10.
Described hoist control valve 5 connection valve controlling device for doors 4, described valve control device 4 controls the opening and closing of hoist control valve 5.
Automatic controlling valve 3 in this control system adopts electrically-controlled valve.
1 be described in detail the whole control process of control system described in the utility model by reference to the accompanying drawings, the whole control process of this hydraulic lifting control system can be divided into thermal energy storage process and energy release process.
Wherein, the control process of thermal energy storage process is as follows: closing switch control cock 7, open switching control valve 15, vehicle is in normal driving process, by engine installation 2 by the hydraulic oil in hydraulic reservoir 1, what continue through check valve I13 is transported in energy storage canister 12, wherein said engine installation 2 can adopt gear type pump, motor-drive pump, gear type pump or motor-drive pump unit, when in energy storage canister 12, oil pressure reaches rated value, the effect of electrically-controlled valve 3 starting protection starts pressure release, close hydraulic-driven path, hydraulic oil flow back in hydraulic reservoir 1 by hydraulic circuit, now thermal energy storage process terminates.
The control process of energy release process is as follows: when dumping car arrives discharge location, during break bulk, by valve control device 4, start hoist control valve 5, the high pressure liquid force feed stored in release energy storage canister 12, the hydraulic oil that hydraulic oil now in energy storage canister 12 is exported steadily by check valve II14, continue is to the elevating ram in hydraulic lifting system, thus when realizing neutral gear, the lifting in compartment is unloaded; Effectively reduce original control system like this to need to restart engine installation and carry out hydraulically powered setup time, make the more traditional lifting of each unloading shorten time about 10s, and fuel oil consumption required when having saved extra startup engine installation.
When need of work, the utility model also simply can be switched to traditional lifting master mode, now only need to close the switching control valve 15 arranged in closed-centre system, open the switching control pilot 7 that hydraulic-driven path is arranged, thus closedown closed-centre system, directly realize the control to hydraulic lifting system by hydraulic-driven path.
Each parts that this hydraulic lifting control system adopts and assembly major part are product conventional on market, design and development cost is lower, layout on car load is also more convenient, reasonable, can realize easily producing in enormous quantities and using, and can save operation cost 3 ~ 50,000 yuan every year.
