Abstract

The utility model discloses a radio remote control electric hydraulic grab. The radio remote control electric hydraulic grab comprises a deck beam, a through beam, a hanging ring, a grab body and a brace rod and is characterized in that the grab also comprises a hydraulic device and a radio remote control device, wherein the hydraulic device is provided with a motor, a hydraulic pump, an oil cylinder, an electromagnetic valve and an oil pipe joint, the hydraulic pump provides power through the motor connected with the hydraulic pump and is connected with and drives the oil cylinder through the electromagnetic valve, and the radio remote control device is connected with and arranged on the through beam. The radio remote control electric hydraulic grab can remotely control the goods grabbing operation of the grab or enable the grab to open, close or stop grabbing and placing the goods through radio remote control under the condition that a cable control line of a crane grab is broken, is adapted to harsh working environments, can work under the condition of high-frequency usage, prolongs the service life of the grab, improves the enterprise efficiency, overcomes the safety hidden troubles in production, and is convenient to operate.

Description

The radio telecommand electric hydraulic bucket

Technical field

The utility model relates to a kind of loading-unload machine, relates in particular to a kind of radio telecommand electric hydraulic bucket.

Background technology

Electric hydraulic bucket is as important composition parts of weight-lifting equipment; But under the abominable working environments such as high temperature is damp and hot, dust flies upward because hoisting crane usually is in, seawater salt fog; Fast at rising or falling speed, high-frequency goes up and down, and bigger pulse tension force is particularly arranged when the cable take-up; Time thinner control line in the cable of long control grab bucket work is easy to broken; Break cable and will cause very big economic loss even also can bring very big potential safety hazard,, can't improve the pulling strengrth of cable through the size that increases cable because cable drum has requirement to be generally about 35mm to the diameter of cable to enterprise.

The utility model content

In view of this, the utility model technical matters to be solved is: provide the grab bucket of a kind of Remote to grasp goods or under the situation that hoisting crane cable control line is broken, still just realize a kind of radio telecommand electric hydraulic bucket of pick-and-place goods through radio telecommand.

In order to achieve the above object, the utility model adopts following technical scheme to realize:

A kind of radio telecommand electric hydraulic bucket; Comprise deck beam, through beam, suspension ring, bucket body, strut; It is characterized in that: said grab bucket also comprises hydraulic efficiency gear and beeper; Said hydraulic efficiency gear is provided with electrical motor, Hydraulic Pump, oil cylinder, electromagnetic valve, tubing interface, and said Hydraulic Pump provides power and connects the said oil cylinder of driving through electromagnetic valve through connected electrical motor, and said beeper is mounted on the through beam.

Said beeper comprises radio remote controller, change-over swith, voltage transformer.

Said strut is installed in deck beam and through beam both sides, and the following hinge of strut lays respectively at the lateral edges of homonymy bucket body.

Said oil cylinder is fixedly installed between the upper and lower bolster, and through beam is connected through hinge and bucket body upper end, and bucket body is along with stretching out with shrinking of the piston rod of oil cylinder opened and closure accordingly.

Can know that by technique scheme the beneficial effect of the utility model is:

Compare prior art; The utility model can Remote grab bucket extracting goods or the unlatching, the closure that under the situation that crane grab cable control line is broken, realize grabbing bucket through radio telecommand, stop to come the pick-and-place goods; Adapt to bad working environment; Can under the high-frequency service condition, work the work life that prolonged grab bucket with 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 the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing about the utility model.

See also Fig. 1 to Fig. 3; The utility model provides a kind of radio telecommand electric hydraulic bucket; Comprise deck beam 1, through beam 2, suspension ring 3, bucket body 5, strut 6; It is characterized in that: said grab bucket also comprises hydraulic efficiency gear and beeper 11; Said hydraulic efficiency gear is provided with electrical motor 7, Hydraulic Pump 4, oil cylinder 8, electromagnetic valve 9, tubing interface 10, and said Hydraulic Pump 4 provides power and connects the said oil cylinder 8 of driving through electromagnetic valve 9 through connected electrical motor 7, and said beeper 11 is mounted on the through beam 2.

Said beeper 11 comprises radio remote controller, change-over swith, voltage transformer.

Said strut 6 is installed in deck beam 1 and through beam 2 both sides, and the following hinge of strut 6 lays respectively at the lateral edges of homonymy bucket body 5.

Said oil cylinder 8 is fixedly installed in upper and lower bolster 1, between 2, through beam 2 is connected with bucket body 5 upper ends through hinge.Goods is grasped in the Remote grab bucket or under the situation that crane grab cable control line is broken, we are transformed into radio telecommand through change-over swith, through beeper 11 control electromagnetic valve 9 of grab bucket, thereby realizes grasping material.

Press electrical motor 7 buttons like Fig. 1-Fig. 4, electrical motor 7 drives Hydraulic Pump 4 through coupler and turns round together, when electromagnetic valve 9 is not switched on; Safety overflow valve E does not have overflow, when electromagnetic valve YV1 switches on, and the control port that control oil gets into right side hydraulic control one-way valve A; Hydraulic control one-way valve A opens, and high pressure oil is reverse to get into oil cylinder rodless cavity KS through right side hydraulic control one-way valve A, and rod chamber KSS oil also gets into rodless cavity KS through check valve A; Realize differential connection, hydraulic cylinder piston rod stretches out fast, accomplishes the grab bucket opening action; At this moment, can insert pressure measurement flexible pipe and compression indicator, detect the rear end KS operation pressure when opening of grabbing bucket through MB pressure measurement electrical measurement crimp head; When electromagnetic valve YV2 switches on, the control port that control oil gets into 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 gets into cylinder rod chamber KSS through check valve C, and 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 the center with the bearing pin that is installed on through beam, through the retraction of oil cylinder; Do inside circular arc motion, bucket body stops after reaching total contact, accomplishes closed action.Can insert pressure measurement flexible pipe and compression indicator this moment through MA pressure tap pressure measuring tie-in, 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 to cut off the power supply, it is too fast to prevent also that also fuel tank hydraulic oil from heating up.

The preferable possible embodiments that the above is merely the utility model is not the claim in order to limitation the utility model, so the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content are done changes, all in like manner is included in the scope of the utility model.
