Description
Technical field
The utility model is related to hydraulic control device field, especially a kind of mobile refuse depot hydraulic cylinder regenerative circuit control
Device processed.
Background technology
Mobile refuse depot is a kind of collection garbage reclamation, the garbage recovery device that compression and storage are integrated.In the prior art
Middle hydraulic cylinder is the device for garbage-compressing the most commonly used in mobile refuse depot.
In hydraulic cylinder works compression process, due to the rubbish stored in originally refuse depot be it is fluffy, in the shape
The workload of hydraulic cylinder is small under state, and the speed of service is fast；But when it runs to certain position, rubbish in refuse depot gradually into
Row compression, the workload of hydraulic cylinder becomes larger at this time, and the speed of service reduces.
The above-mentioned course of work need to be controlled through its control device, and the rod chamber and rodless cavity of existing hydraulic cylinder pass through respectively
One oil circuit is connected with working connection, and multiple electromagnetic switch valves are equipped in above-mentioned branch oil circuit for controlling it, but
In actual use, above-mentioned mounting structure there is a problem of certain, due to carrying out electrical control using electromagnetic switch valve, because
This existing structure needs more complicated control device in use, and in addition to this, above-mentioned electromagnetic switch valve was using
It is not controlled according to real-time pressure in journey, but is opened and closed for electrical control, therefore high low speed switching difficult to realize
The smooth transition of process, be easy to cause the impact of hydraulic cylinder, and the leakage of hydraulic cylinder oil circuit is may also result in when serious.
Utility model content
It the purpose of the utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable for structure, is not necessarily to electrical control,
A kind of mobile refuse depot hydraulic cylinder regenerative circuit control device to operate steadily.
The utility model is achieved through the following technical solutions：
A kind of mobile refuse depot hydraulic cylinder regenerative circuit control device, including an oil cylinder, the rod chamber and nothing of the oil cylinder
Rod cavity is connected by two working connections respectively, it is characterised in that：In the working connection being connected with the rod chamber and and rodless cavity
It is connected by a working oil path between the working connection being connected, a control closed type check valve is installed in the working oil path,
One is equipped in the working connection being connected with the rod chamber to contend with valve, the control mouth of the valve that contends with by a control oil circuit and
Control closed type check valve is connected with the working oil path of rodless cavity homonymy, controls the control mouth of closed type check valve and the valve that contends with
End be connected by pipeline.
The advantages of the utility model and good effect are：
In the utility model, the structure using the valve cooperation control closed type check valve that contends with replaces original multiple electromagnetic switch
The structure of valve, in use, the valve that contends with are used to adjust the back pressure of oil return, to control the steady of its load, work as hydraulic cylinder
It is small in workload, the valve that not up to contends with setting value, at this time hydraulic oil be connected through check valve, hydraulic cylinder is in the speed of service
When fast state, when it is in, workload is big, reaches the value for the valve setting that contends with, and hydraulic oil is through the valve conducting that contends with, hydraulic pressure at this time
Cylinder is in the slow state of the speed of service, to replace original complexity electrical control gear and multiple electromagnetic switch valves structure,
In addition, also effective Feedback can be carried out to pressure, ensures the stabilization in hydraulic cylinder operational process, promote the safety of oil circuit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
It elaborates to the utility model below by embodiment, the embodiment is illustrative instead of limiting
, protection scope of this utility model cannot be limited by this.
A kind of mobile refuse depot hydraulic cylinder regenerative circuit control device, including an oil cylinder 1, the rod chamber and nothing of the oil cylinder
Rod cavity is connected by crossing two working connections respectively, and the innovation of the utility model is, in the working connection 8 that is connected with the rod chamber
It is connected by a working oil path 3 between the working connection 2 being connected with rodless cavity, control pass is installed in the working oil path
Closed form check valve 7 is equipped with one in the working connection being connected with the rod chamber and contends with valve 6, and the control mouth of the valve that contends with is logical
It crosses a control oil circuit 4 and control closed type check valve is connected with the working oil path of rodless cavity homonymy, control closed type check valve
Control mouth be connected by pipeline 5 with the end for the valve that contends with.
The course of work of the utility model is：
When the utility model is used, operating personnel are first configured the valve that contends with, and the valve that contends with after being arranged is for adjusting
The back pressure for saving oil return, to control the steady of its load, when hydraulic cylinder is in, workload is small, the valve that not up to contends with setting
Value, hydraulic oil is connected through check valve at this time, when hydraulic cylinder is in the speed of service fast state, when to be in workload big for it, reaches
To the value for the valve setting that contends with, for hydraulic oil through the valve conducting that contends with, hydraulic cylinder is in the slow state of the speed of service at this time.
In the utility model, the structure of original multiple electromagnetic switch valves is replaced using the structure for the valve cooperation check valve that contends with,
There is no need to the structures of complicated electrical control gear and multiple electromagnetic switch valves, in addition, in use can also be to pressure
Effective Feedback is carried out, ensures the stabilization in hydraulic cylinder operational process, promotes the safety of oil circuit.
