Description
Technical field
The utility model belongs to vehicle drive unit and jointly controls, and relates in particular to driving device and brake system and adopts the device that jointly controls.
Background technology
The discharging of dumping car transportation bulk material is quick, the efficient height.Because machinery and artificial origin, dumping car the lifting compartment often occurs and travels, and collision is located at pipeline, electric power and communication cable, the Architectural Equipment in the road sky etc., leads to a disaster, and causes great personal casualty and property damage.Therefore, the safety traffic of dumping car causes people's very big concern.China utility model patent disclose a kind of: " dumping car compression air brake lifting electric interlocking installation " (ZL99228333.7), this device is made up of pneumatic electric switch, manual electrical switch, tee connection, electromagnetic valve, manual power switch, electromagnetic valve are connected with the pneumatic switch circuit respectively, pneumatic electric switch is connected with T-pipe joint, and electromagnetic valve also is connected with Parking maneuvering valve, Parking relay valve gas circuit respectively.After the compartment lifting, pneumatic electric switch pressurized, car brakeing is in the Parking state; The compartment falls behind down, and pneumatic electric switch unclamps, and braking during standstill is removed, and vehicle can start, travel.Its defective is: pneumatic electric switch is loaded on outside the compartment, owing to corrosion, sludge blockage, swing arm fatigue are undermined reasons such as artificial damage, cause failure of apparatus, fault is many, maintenance is big, spare parts consumption is many, and the vehicle attendance rate reduces, and even more serious is can have the hidden danger that crashes after pneumatic electric switch loses efficacy.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of body of tipper carriage lifting and Parking interlock system, when the compartment lifting, force to enable braking during standstill, after the compartment falls and resets, braking during standstill is removed, vehicle can travel, and control is sensitive, reliable, guarantees traffic safety; And easy care, fault rate are low, vehicle attendance rate height.
Body of tipper carriage lifting and Parking interlock system comprise compartment lifting hydraulic efficiency gear and air pressure holding brake device, are characterized in that lifting hydraulic efficiency gear in compartment is connected to form by the road by hydraulic reservoir, lifting oil pump, check valve, elevating ram, limit valve; The air pressure holding brake device is connected to form by the road by air receiver, hand brake valve, electromagnetic valve, relay valve, brake cylinder; In the hydraulic tubing of compartment lifting hydraulic efficiency gear pressure switch is set, establishes electromagnetic valve in the air pressure holding brake device pneumatic line, pressure switch is connected with electromagnetic valve circuit, all is connected on the vehicle power.When the compartment was lifted to most significant bit, the hydraulic tubing oil pressure reached peak value; When the compartment fell to resetting, the hydraulic tubing oil pressure was reduced to valley.Utilize the variation of hydraulic tubing oil pressure, be converted into electric signal, be sent to electromagnetic valve,, thereby realize compartment lifting and vehicle ' interlocking with the open and close of control braking during standstill switch by pressure switch.
The utility model further improves, described pressure switch is connected on the hydraulic tubing by T-pipe joint, at the pipeline oil pressure greater than setting pressure (be compartment when falling reset position in the hydraulic tubing instantaneous oil pressure), provide a closed electric signal, be delivered to electromagnetic valve, thereby braking during standstill is started working, and vehicle can not travel; During less than setting pressure, provide the disconnection electric signal at the pipeline oil pressure, unclamp braking during standstill, vehicle can cruising; Pressure switch must be able to be born the peak value oil pressure in the hydraulic tubing.
Advantage is: simple and reasonable for structure, volume is little, and is easy for installation; Control is sensitive, reliable, has guaranteed the safety of driving; Fragile and lost efficacy, low, the easy care of fault rate has not improved the vehicle attendance rate, has also saved the spare part expense.
Description of drawings
The utility model is described in further detail for the contrast accompanying drawing below.
Fig. 1 is body of tipper carriage lifting and braking during standstill interlock system hydraulic diagram.
Fig. 2 is the air pressure control scheme drawing of body of tipper carriage lifting and braking during standstill interlock system.
The specific embodiment
By Fig. 1, Fig. 2 as can be seen, body of tipper carriage lifting and braking during standstill interlock system are made up of the lifting hydraulic efficiency gear and the braking during standstill pneumatics in compartment.The lifting hydraulic efficiency gear in compartment is connected to form by the road by hydraulic reservoir 3, lifting oil pump 2, check valve 1, elevating ram 7, limit valve 9, and hydraulic tubing is established gas control maneuvering valve 5, storage tank 6 and air control lifting valve 8.Hydraulic tubing is provided with T-pipe joint, and pressure switch and T-pipe joint connect.The braking during standstill pneumatics is connected to form by the road by air receiver 12, hand brake valve 11, relay valve 13, brake cylinder 14, establishes electromagnetic valve 10 on pneumatic pipeline, and pressure switch 4 is connected with electromagnetic valve 10 circuit.Electromagnetic valve 10 is a two position three-way valve, is provided with in pairs, is connected with four drag wheel cylinders 14 respectively, and gas circuit communicates.Hand brake valve 11 is communicated with sources of the gas, and after the brake cylinder inflation, the spring pressurized in it reaches setting value, opens mechanical linkage, removes braking during standstill, and vehicle can cruising; When lifting hydraulic tubing oil pressure surpassed setting pressure, pressure switch 4 provided an electric signal to electromagnetic valve 10, electromagnetic valve 10 closures, and to disconnect pneumatic pipeline, vehicle is in the braking during standstill state, and operate manual brake activation valve and can not change the Parking state this moment.When the compartment was lifted to most significant bit, the hydraulic tubing oil pressure reached peak value; When the compartment fell to resetting, the hydraulic tubing oil pressure was reduced to valley.Utilize the variation of hydraulic tubing oil pressure, be converted into electric signal, be sent to electromagnetic valve,, thereby realize compartment lifting and vehicle ' interlocking with the open and close of control braking during standstill switch by pressure switch.
