Summary of the invention
In view of this; technical matters to be solved by this invention is: provide a kind of Grabbing properties good, safe and reliable; need not hoisting crane the self-powered pick-and-place goods of realizing of grabbing bucket that passes through of power supply is provided, a kind of radio telecommand diesel-engined drive hydraulic grab of position limitation protection effect is provided in the middle of hydraulic grab is being opened work with closure simultaneously.
in order to achieve the above object, the present invention adopts following technical scheme to realize: a kind of radio telecommand diesel-engined drive hydraulic grab, comprise suspension ring, shackle, shell, through beam, bucket body, hydraulic efficiency gear, beeper, described hydraulic grab also comprises connecting rod, described connecting rod is completed when bucket body and is played spacing and protective effect to bucket body when opening with closed action, described hydraulic efficiency gear is provided with Hydraulic Pump, oil cylinder, the control cock block system, described Hydraulic Pump provides power and connects by electromagnetic valve by connected diesel engine and drives described oil cylinder, the receiver of remote-control sytem of described beeper is mounted on the grab bucket shell, described diesel engine, hydraulic efficiency gear is arranged on enclosure, be arranged on through beam, described control cock block system comprises electromagnetic valve YV1, electromagnetic valve YV2, check valve A, check valve B, check valve C, safety valve D, safety overflow valve E, blowdown valve F, shuttle valve G.
Described beeper comprises remote controller and receiver of remote-control sytem.
Described bucket body bottom is connected with through beam by bearing pin; the two ends of connecting rod are connected in respectively the inside edge of two bucket bodies by bearing pin; bucket body is along with stretching out of the piston rod of oil cylinder opened and closure accordingly with shrinking; connecting rod is tending towards level when bucket body is opened; connecting rod is in oblique position when bucket body is closed, plays spacing and protective effect to the grab bucket open and close.
Described oil cylinder is connected with the bucket body upper end by hinge.
Described suspension ring connect by bearing pin with shackle.
The present invention is the bivalve hydraulic grab, and same principle can produce many lobes hydraulic grab as required.
As shown from the above technical solution, the invention has the beneficial effects as follows:
compared to existing technology, the present invention can be in the situation that do not have hoisting crane that power supply is provided, the unlatching of grabbing bucket by the self-powered diesel engine and realizing by radio telecommand of grabbing bucket, closed, stop coming the pick-and-place goods, adapt to abominable working environment, in the middle of opening work with closure, hydraulic grab provide the position limitation protection effect to get rid of very large potential safety hazard by connecting rod simultaneously, the present invention is by realizing the off-load pressurize in whole loop with safety overflow valve, solved the large problem of Hydraulic System Fever amount, can work under the high-frequency service condition and extended the work life of grab bucket and improved the efficient of enterprise and overcome the potential safety hazard of producing, and easy to operate.

The specific embodiment
In order to make those skilled in the art can further understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing.
see also Fig. 1 to Fig. 3, in order to achieve the above object, the present invention adopts following technical scheme to realize: a kind of radio telecommand diesel-engined drive hydraulic grab, comprise suspension ring 1, shackle 2, shell 4, through beam 11, bucket body 8, hydraulic efficiency gear, beeper, described hydraulic grab also comprises connecting rod 7, described connecting rod 7 is completed when bucket body 8 and bucket body is played position-limiting action when opening with closed action, described hydraulic efficiency gear is provided with Hydraulic Pump 6, oil cylinder 5, control cock block system 10, described Hydraulic Pump 6 provides power and connects by electromagnetic valve by connected diesel engine 3 and drives described oil cylinder 5, the receiver of remote-control sytem 9 of described beeper is mounted on grab bucket shell 4, described diesel engine 3, hydraulic efficiency gear is arranged on shell 4 inside, be arranged on through beam 11, described control cock block system comprises electromagnetic valve YV1, electromagnetic valve YV2, check valve A, check valve B, check valve C, safety valve D, safety overflow valve E.
Described beeper comprises remote controller 12 and receiver of remote-control sytem 9.
Described bucket body bottom is connected with through beam 11 by bearing pin; the two ends of connecting rod 7 are connected in respectively the inside edge of two bucket bodies 8 by bearing pin; bucket body 8 is along with stretching out of the piston rod of oil cylinder 5 opened and closure accordingly with shrinking; connecting rod 7 is tending towards level when bucket body is opened; connecting rod 7 is in oblique position when bucket body is closed, plays spacing and protective effect to the grab bucket open and close.
Described oil cylinder 5 is connected with bucket body 8 upper ends by hinge.
Described suspension ring 1 are connected with shackle and are connected by bearing pin.
press the button of remote controller 12 as Fig. 1-Fig. 3, diesel engine 3 drives Hydraulic Pump 6 by coupler and turns round together, when electromagnetic valve is not switched on, safety overflow valve E is without overflow, when electromagnetic valve YV1 switches on, control the control port that oil enters right side hydraulic control one-way valve A, hydraulic control one-way valve A opens, high pressure oil is reverse enters oil cylinder rodless cavity KS by right side hydraulic control one-way valve A, rod chamber KSS oil also enters rodless cavity KS by check valve A, realize differential connection, hydraulic cylinder piston rod stretches out fast, complete the grab bucket opening action, connecting rod 7 be in the trend level to bucket body 8 open amplitude play the restriction and the safety guard-safeguard effect, at this moment, can be by MB pressure measurement electrical measurement crimp head access pressure measurement flexible pipe and compression indicator, detect the rear end KS operation pressure when opening of grabbing bucket, when electromagnetic valve YV2 switches on, control the control port that oil enters left side hydraulic control one-way valve B, hydraulic control one-way valve B opens, the high pressure oil that flows out from pump simultaneously, enter cylinder rod chamber KSS through check valve C, rodless cavity KS oil return is through the reverse outflow of left end hydraulic control one-way valve B, flow back to mailbox through the oil return filter, skip body is centered by the bearing pin that is installed on through beam, by the retraction of oil cylinder, do inside circular arc motion, bucket body stops after reaching full contact, complete closed action, connecting rod 7 plays buffer limit and protective effect when being at this moment oblique position to bucket body 8 closure.This moment can be by MA pressure tap pressure measuring tie-in access pressure measurement flexible pipe and compression indicator, rod end KSS operation pressure when the detection grab bucket is closed; After the grab bucket closure, rod end KSS pressure rises to the force value that safety valve D sets, main by pass valve can the low discharge state under off-load, and guarantee that oil cylinder piston pressure is all the time in setting value, thereby improper the opening of grab bucket when preventing from cutting off the power supply can prevent also that also fuel tank hydraulic oil from heating up too fast.
