Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figures 1 to 6, a kind of wireless single suspension centre automatic open-close type grab bucket, comprises two Hubei Province bucket 5, two pull bars 3, knock-off joint 6, slip sash weight 2, two steel rope 7 and single acting oil cylinders 1.
Two Hubei Province buckets 5 to be hinged formation normal-running fit through hinge 4, struggle against with two Hubei Province respectively and 5 to be connected in the lower end of two pull bars 3, the upper end of two pull bars 3 respectively with the connection of knock-off joint 6, the perforate of passing for the sash weight 2 that slides is offered in the centre of knock-off joint 6; Slip sash weight 2 and single acting oil cylinder 1 are arranged at the top of hinge 4, and the upper end of single acting oil cylinder 1 is connected with slip sash weight 2, and the lower end of single acting oil cylinder 1 is fixedly connected with hinge 4.
The lower end of two steel ropes 7 is each passed through slip sash weight 2 and is fixedly connected with knock-off joint 6 afterwards, and steel rope 7 and slip sash weight 2 form bearing fit.
Single acting oil cylinder 1 comprises cylinder barrel 12, piston rod 11 and piston 13, the upper end of piston rod 11 is connected with slip sash weight 2, the lower end of cylinder barrel 12 is fixedly connected with hinge 4, the lower end of piston rod 11 to be stretched in cylinder barrel 12 and is connected piston 13, the lumen segmentation of cylinder barrel 12 is become rod chamber and rodless cavity by piston 13, piston 13 is provided with for controlling the unidirectional electromagnetic throttle valve 14 leaked into by hydraulic oil in rod chamber in rodless cavity.
For realizing Wireless remote control, unidirectional electromagnetic throttle valve 14 is wireless unidirectional electromagnetic throttle valve 14; Grab bucket also comprises radio remote control switch, and radio remote control switch controls wireless unidirectional electromagnetic throttle valve 14 and works.
For making better to coordinate between steel rope 7 with slip sash weight 2, reduce friction force between the two, the both sides of slip sash weight 2 are separately installed with pulley, and be connected with knock-off joint 6 after pulley is walked around in the lower end of steel rope 7, being formed between steel rope 7 with slip sash weight 2 rolls coordinates.
The upper end also comprising a rope socket 8, two steel rope 7 is connected with rope socket 8 respectively.Can be connected with lifting machine through this rope socket 8.
When grab bucket is in open mode, the piston rod 11 of single acting oil cylinder 1 is in elongation state, now grab bucket is put on material, due to the one-way performance of single acting oil cylinder 1 and supporting unidirectional electromagnetic throttle valve 14, under the effect that slip sash weight 2 is conducted oneself with dignity, rely on gravity the piston rod 11 of single acting oil cylinder 1 to be compressed to the bottom of oil cylinder rodless cavity, in-oil cylinder hydraulic oil is expelled to rod chamber through unidirectional electromagnetic throttle valve 14.Now the piston rod 11 of single acting oil cylinder 1 is compressed to most short status, slip sash weight 2 sinks down into lowermost end accordingly, the sash weight of crane loading slip subsequently 2, due to the one-way performance of single acting oil cylinder 1 and unidirectional electromagnetic throttle valve 14, now hydraulic oil cannot be back to rodless cavity, hydraulic ram rodless cavity unidirectional blocking, is in packing state, stops stretching out of the piston rod 11 of single acting oil cylinder 1.Now single acting oil cylinder 1 can only, with contraction state, together with slip sash weight 2, drive hinge 4 to move simultaneously, thus Hubei Province bucket 5 is closed and captures material lifting.
When being in the closure state after capturing material when grabbing bucket, the piston rod 11 of single acting oil cylinder 1 is in contraction state, now operating personal radio remote control switch opens unidirectional electromagnetic throttle valve 14, remove packing state, the hydraulic oil in rod chamber is made to leak in rodless cavity, now under the Action of Gravity Field of material, the piston rod 11 of single acting oil cylinder 1 is drawn out, hinge 4 stretches out with piston rod 11 and moves down, Hubei Province bucket 5 is made to open (now, the elongation speed of single acting oil cylinder 1 piston rod 11 can set with adjustment flow regulating valve, the time that single acting oil cylinder 1 is stretched to most long status from most short status is exactly the times that Hubei Province bucket 5 is opened), thus can with height, the material captured be discharged on stacking point at any time, after having discharged, Hubei Province bucket 5 is in aerial open mode, the process once capturing material terminates.So namely complete a working cycle.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
