Abstract
The utility model discloses a hydraulic protection device for a compression type garbage truck. The hydraulic protection device comprises a hoisting hydraulic cylinder and a hydraulic pump, wherein the hoisting hydraulic cylinder is connected with the hydraulic pump through an oil inlet pipeline and an oil return pipeline. The hydraulic protection device is characterized in that a bidirectional hydraulic lock is arranged on the oil return pipeline of the hoisting hydraulic cylinder; and a unidirectional throttling speed regulation valve is arranged at the oil return pipeline section between the hoisting hydraulic cylinder and the bidirectional hydraulic lock. During unloading of garbage, in spite of explosion of an oil pipe or oil leakage of an oil joint of a hydraulic system, the hoisting hydraulic cylinder and a loader on the hoisting hydraulic cylinder cannot fall down suddenly due to the bidirectional hydraulic lock; and sanitation workers who are working and operating vehicles can be protected actively.
Description
Technical field
The utility model relates to a kind of compression type garbage truck, and is especially relevant with the hydraulic efficiency pressure system of compression type garbage truck.
Background technology
Compression type garbage truck because of its load convenient, compressed capability is strong, good leak tightness can avoid secondary pollution in the clean rubbish process to become the key motorcycle type of refuse collection trucks effectively.It mainly comprises car chassis, compartment, push pedal and rammer.Slide plate and scraper component are installed in the above-mentioned rammer.The bottom of rammer is an arcuate structure, and and arranged on left and right sides is furnished with slideway, and being equipped with in the slideway can be along the slide plate of the upper and lower slip of slideway, and the motion of slide plate relies on two the sliding plate hydraulic cylinders (oil cylinder) that are fixed on the rammer to drive.Slide plate top is provided with scraper plate, and the rotation of scraper plate provides power by two the scraper plate hydraulic actuating cylinders (oil cylinder) that are fixed on the slide plate.The rammer rear portion is provided with rubbish and goes into railway carriage or compartment mechanism, turns over a barrel hydraulic actuating cylinder (oil cylinder) by left and right two and realizes the rubbish input.After rubbish was rendered to rammer, scraper plate opened, and the downward slippage of slide plate is behind desired location; Drive lower scraping plate at oil cylinder rotates at the bottom of the arc of lower edge; Then slide plate drives scraper plate and upwards slides and take rubbish to the compartment the inside, and push pedal this moment has placed the compartment rearmost end, and the rubbish that slide plate drives is when reaching certain limit to the slide plate squeese pressure; Move after under push pedal promotes, being compelled, realize that rubbish is compressed into the railway carriage or compartment.After filling rubbish in the compartment, at first open the catch gear between compartment and the rammer, be separately fixed at lifting hydraulic cylinder between compartment and the rammer by two ends then and drive rammer and do along hinge and rotate counterclockwise until level attitude.At this moment, tail is opened fully behind the compartment, and push pedal hydraulic actuating cylinder drive push pedal is moved behind the railway carriage or compartment rubbish is unloaded.But in actual use, can't avoid because the unusual damage phenomenon that causes appears in the hydraulic part of lifting hydraulic cylinder, and cause damaged vehicle, weight person jeopardizes the safety of operating personal.
The utility model content
The task of the utility model is to solve the technological deficiency of the hydraulic part existence that has lifting hydraulic cylinder in the compression type garbage truck now, and a kind of compression type garbage truck hydraulic protector is provided.
Its technical solution is:
A kind of compression type garbage truck hydraulic protector comprises lifting hydraulic cylinder and Hydraulic Pump, and lifting hydraulic cylinder is connected Hydraulic Pump through chargine line with oil return line; The oil return line of lifting hydraulic cylinder is provided with bidirectional hydraulic lock, and the oil return pipe highway section between lifting hydraulic cylinder and the bidirectional hydraulic lock is provided with one-way throttle valve.
Only when reaching setting hydraulic pressure value, it is unimpeded that its chargine line and oil return line side keep for the hydraulic efficiency pressure system of above-mentioned lifting hydraulic cylinder.
Above-mentioned compression type garbage truck hydraulic protector also comprises push pedal hydraulic actuating cylinder, sliding plate hydraulic cylinder, scraper plate hydraulic actuating cylinder and turns over a barrel hydraulic actuating cylinder; Above-mentioned push pedal hydraulic actuating cylinder, sliding plate hydraulic cylinder, scraper plate hydraulic actuating cylinder and turn over barrel hydraulic actuating cylinder and be connected Hydraulic Pump through advancing separately, oil return line respectively.
The utlity model has following useful technique effect:
The utility model is in the rubbish uninstall process; No matter be the oil pipe explosion or the oily joint leakage of oil of hydraulic efficiency pressure system; Because of the setting of bidirectional hydraulic lock, lifting hydraulic cylinder and the rammer that carries thereof all can not descend suddenly, can the active safety protection be provided to environmental sanitation personnel and the vehicle of operating.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Figure is the structural principle scheme drawing of a kind of embodiment of the utility model.
The specific embodiment
In conjunction with accompanying drawing, a kind of compression type garbage truck hydraulic protector comprises lifting hydraulic cylinder 1, push pedal hydraulic actuating cylinder 2, sliding plate hydraulic cylinder 3, scraper plate hydraulic actuating cylinder 4, turns over barrel hydraulic actuating cylinder 5 and Hydraulic Pump 6.Above-mentioned lifting hydraulic cylinder is connected Hydraulic Pump with oil return line through chargine line, other hydraulic actuating cylinders such as push pedal hydraulic actuating cylinder, sliding plate hydraulic cylinder, scraper plate hydraulic actuating cylinder and turn over barrel hydraulic actuating cylinder and also be connected Hydraulic Pump through advancing separately, oil return line respectively.The oil return line of above-mentioned lifting hydraulic cylinder is provided with bidirectional hydraulic lock 7, and the oil return pipe highway section between lifting hydraulic cylinder and the bidirectional hydraulic lock is provided with one-way throttle valve 8; One-way throttle valve is as back pressure valve.
Its principle of work roughly is:
When the environmental sanitation personnel through after controlling joystick or automatic button and making rammer give rise to certain altitude, the push pedal hydraulic actuating cylinder drives push pedal and behind the compartment forward direction, releases the rubbish that has compressed.Unload in the whole process at rubbish; Because the loop of lifting hydraulic cylinder is provided with bidirectional hydraulic lock and throttling governing valve, can make the oil return flow velocity balanced, promptly the lifting hydraulic cylinder piston rod is regained the speed equilibrium; Problem is shaken in the part of avoiding occurring impacting when rammer falls; When the external control hydraulic oil of certain pressure got into the hydraulic lock outside control mouth, main valve plug was opened, and oil return line connects.If sudden inefficacy (like oil pipe explosion, oily joint leakage of oil) appears in hydraulic efficiency pressure system; When oil pressure is lower than setting value; Hydraulic lock carries out that " " protection, promptly the lifting hydraulic cylinder piston rod can not descend suddenly lock, to the environmental sanitation personnel that operating and vehicle initiatively protection is provided.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
