Abstract
The utility model discloses a tipping bucket drive mechanism of a dust cart and a dust cart provided with the tipping bucket drive mechanism. The tipping bucket drive mechanism includes an oil cylinder used for driving the tipping bucket to turn over, and a hydraulic drive loop connected with the oil cylinder; the hydraulic drive loop includes a control valve and a reversing valve; the tipping bucket drive mechanism also includes a detecting device used for detecting the turning-over position of the tipping bucket so as to adjust the motion states of the control valve and the reversing valve. By arranging the detecting device at a proper position to control the motion of the oil cylinder, the tipping bucket can disconnect the drive of high pressure oil on the oil cylinder after passing through the set position so as to slowly fall to the ground by relying on the self-dead weight of the tipping bucket; therefore, the tipping bucket can be guaranteed to fall to the ground safety so as to improve the safety and the service lives of the tipping bucket and the dust cart.
Description
Technical field

The utility model proposes a kind of tipping bucket driver train of waste-skip at above-mentioned technical matters, comprise in order to drive the oil cylinder and the hydraulic drive circuit that links to each other with this oil cylinder of tipping bucket upset, this hydraulic drive circuit comprises control cock and change-over valve, and this tipping bucket driver train also comprises the upturned position that is used for detecting this tipping bucket detecting device with the operating state of adjusting this control cock and change-over valve.
This detecting device is to provide to adjust this control cock to meta and adjust the device of the signal of this change-over valve commutation when this tipping bucket is turned to a desired location downwards.
In an embodiment of utility model, this control cock is an electromagnetic valve.This change-over valve is an electromagnetic valve.This detecting device is near switch.This oil cylinder is a double acting single-rod piston formula oil cylinder.This hydraulic drive circuit comprises first branch road that is communicated with the rod chamber of this oil cylinder and second branch road that is communicated with the rodless cavity of this oil cylinder, this control cock is the valve whether hydraulic oil is provided to this first branch road and/or second branch road in order to control, and this change-over valve is to provide to this first branch road or the valve of this second branch road in order to modulated pressure oil.The number of described oil cylinder is two, lays respectively at the both sides of this tipping bucket.
The utility model also proposes a kind of waste-skip at above-mentioned technical matters, and it has tipping bucket and the above-mentioned tipping bucket driver train that links to each other with tipping bucket.
Compared with prior art, the tipping bucket driver train of waste-skip of the present utility model and have the waste-skip of this tipping bucket driver train, by detecting device in position being set and controlling the action of oil cylinder by the signal that this detecting device provides, can make tipping bucket rely on the self gravitation of tipping bucket slowly to land to the driving of oil cylinder through disconnecting high pressure oil after this desired location, thereby can guarantee that tipping bucket safety contacts to earth, to improve the safety and the service life of tipping bucket and waste-skip.
Description of drawings
Fig. 1 is the structural representation of the tipping bucket driver train embodiment of waste-skip of the present utility model.
Fig. 2 is the hydraulic-driven scheme drawing of the tipping bucket driver train embodiment of waste-skip of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is given elaboration further.
Illustrated in figures 1 and 2 is the structure of tipping bucket driver train embodiment of the present utility model.This tipping bucket driver train comprises in order to drive the oil cylinder 31 and the hydraulic drive circuit 32 that links to each other with this oil cylinder 31 of tipping bucket upset, this hydraulic drive circuit 32 comprises control cock 321 and change-over valve 322, and this tipping bucket driver train comprises that also the upturned position that is used for detecting tipping bucket 2 is to adjust the detecting device 33 of this control cock 321 and the operating state of change-over valve 322.Wherein,
Detecting device 33 is that a kind of providing when this tipping bucket 2 is turned to a desired location downwards adjusted this control cock 321 to meta and adjust the device of the signal of these change-over valve 322 commutations.
In a specific design of utility model, this control cock 321 is electromagnetic valves.This change-over valve 322 is electromagnetic valves.This detecting device 33 is near switch.This oil cylinder 31 is double acting single-rod piston formula oil cylinders.This hydraulic drive circuit 32 comprises first branch road 323 that is communicated with the rod chamber of this oil cylinder and second branch road 324 that is communicated with the rodless cavity of this oil cylinder, this control cock 321 is the valves whether hydraulic oil is provided to this first branch road 323 and/or second branch road 324 in order to control, and this change-over valve 322 is to provide to this first branch road 323 or the valve of this second branch road 324 in order to modulated pressure oil.The number of oil cylinder 31 is two, lays respectively at the both sides of this tipping bucket 2.
The principle of work of tipping bucket driver train of the present utility model roughly comprises: because the laden height slippage of waste-skip is limited, be provided with near switch by near the appropriate location the pivoted arm of tipping bucket 2, when tipping bucket 2 drops to setting height, near switch motion, order about control cock 321 and return meta, cut off original oil circuit, order about change-over valve 322 commutations simultaneously, make the rod chamber and the rodless cavity conducting of oil cylinder 31, thereby make oil cylinder 31 enter the dry run state.Tipping bucket 2 can slowly descend until contacting to earth under the self gravitation effect, because at this moment tipping bucket 2 is in the free floating state, can not cause impaired because of the effect of external force.
Compared with prior art, the tipping bucket driver train of waste-skip of the present utility model and have the waste-skip of this tipping bucket driver train, features simple structure, fundamentally can accomplish initiatively to adapt to the stressed bad working environments of tipping bucket and realize safety contact to earth, thereby the service life of having improved tipping bucket and even car load greatly.
Need to prove that above-mentioned detecting device 33 is not defined as near switch, also can be other the position that can detect tipping bucket 2 and provide the device of corresponding detection signals, such as: the light detection means of reflective or direct-injection type.Control cock 321 and/or change-over valve 322 are not defined as electromagnetic control type, can be mechanically controlled type, air operated control formula or electrical control formula etc. yet.When the state that the detection signal that provides when detecting device 33 can not directly order about control cock 321 and/or change-over valve 322 changes, when perhaps needing to realize more flexibly control algorithm, can realize function corresponding by control desk is set, this is known for those of ordinary skill in the art, does not repeat them here.
Foregoing; it only is preferred embodiment of the present utility model; be not to be used to limit embodiment of the present utility model; those of ordinary skills are according to main design of the present utility model and spirit; protection domain of the present utility model can carry out corresponding flexible or modification very easily, so should be as the criterion with the desired protection domain of claims.
