Abstract
The utility model relates to a control device, in particular to the control device for a pushing mechanism, and provides the control device for the pushing mechanism. The control device for the pushing mechanism comprises a cylinder, a throttle valve, a pressure reducing valve, a dual pneumatic control valve, a single pneumatic control valve, a handle valve and a button switch; the button switch is connected with the single pneumatic control valve; the single pneumatic control valve is connected with the handle valve; the handle valve is connected with the dual pneumatic control valve; the dual pneumatic control valve is connected with the rodless chamber of the cylinder through the pressure reducing valve; and the dual pneumatic control valve is connected with the rod chamber of the cylinder through the throttle valve. The control device for the pushing mechanism has the beneficial effects that the inching control can be realized in the form of combining the button switch and an operating handle; the cylinder can operate through pressing the button switch by a hand and converting the handle valve and a side frame can enter and exit; when the hand leaves the button switch, the side frame stops moving immediately; and therefore, the safety can be ensured sufficiently.
Description
Technical field
The utility model relates to control gear, relates in particular to a kind of control gear of driving mechanism.
Background technique
General side frame driving mechanism, propulsion mode is: 1, loose one's grip after the manually-operable forwarding button, driving mechanism advances voluntarily, manually clap emergency stop button as urgency, side frame stops, after the trouble shooting, recover emergency stop button, side frame moves on, and returns as needs, and the operation back gets final product; 2, manually-operable bat-handle switch, manually rotation was to " an advancing " side when side frame advanced, and driving mechanism advances voluntarily, rotation is to " a returning " side when returning, driving mechanism is return voluntarily, as urgency rotary switch is rotated to the neutral position, and side frame is out of service.Because all there is same problem in these two kinds of operation formats: operator have operated after button or the bat-handle switch, side frame all can advance voluntarily, this moment, operator can carry out other work, need anxious stopping as emergency case, operator need remove to clap emergency stop button or operation rotatable handle, because have people's reaction time speed and the factor that manually-operable needs the time, so can not effectively avoid dangerous generation.
Summary of the invention
In order to solve the problems of the prior art, the utility model provides a kind of control gear of driving mechanism.
The utility model provides a kind of control gear of driving mechanism, comprise cylinder, throttle valve, reduction valve, double gas control valve, single Pneumatic valve, handle valve and push-button switch, described push-button switch is connected with described single Pneumatic valve, described single Pneumatic valve is connected with described handle valve, described handle valve is connected with described double gas control valve, described double gas control valve is connected with the rodless cavity of described cylinder by reduction valve, and described double gas control valve is connected with the rod chamber of described cylinder by throttle valve.
As further improvement of the utility model, described handle valve is two five-way handle valves.
As further improvement of the utility model, described single Pneumatic valve is two-bit triplet list Pneumatic valve.
As further improvement of the utility model, described double gas control valve is pressure type double gas control valve in the three-position five-way.
As further improvement of the utility model, described reduction valve is the reduction valve of band adverse current function.
The beneficial effects of the utility model are: pass through such scheme, the form that adopts push-button switch to combine with operating grip, can realize crawl control, the hand push-button switch, the transfer handle valve, cylinder can move, side frame can pass in and out, hand leaves push-button switch, and side frame stops mobile immediately, fully guarantees safety.
Description of drawings
Fig. 1 is the structural representation of the control gear of a kind of driving mechanism of the utility model.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Drawing reference numeral among Fig. 1 is: cylinder 1; Throttle valve 2; Reduction valve 3; Pressure type double gas control valve 4 in the three-position five-way; Two-bit triplet list Pneumatic valve 5; Two five-way handle valves 6; Push-button switch 7.
As shown in Figure 1, a kind of control gear of driving mechanism, comprise cylinder 1, throttle valve 2, reduction valve 3, double gas control valve, single Pneumatic valve, handle valve and push-button switch 7, described push-button switch 7 is connected with described single Pneumatic valve, described single Pneumatic valve is connected with described handle valve, described handle valve is connected with described double gas control valve, and described double gas control valve is connected with the rodless cavity of described cylinder 1 by reduction valve 3, and described double gas control valve is connected with the rod chamber of described cylinder 1 by throttle valve 2.
As shown in Figure 1, described handle valve is two five-way handle valves 6.
As shown in Figure 1, described single Pneumatic valve is two-bit triplet list Pneumatic valve 5.
As shown in Figure 1, described double gas control valve is pressure type double gas control valve 4 in the three-position five-way.
As shown in Figure 1, described reduction valve is the reduction valve 3 of band adverse current function.
The control gear of a kind of driving mechanism that the utility model provides, the form that adopts push-button switch 7 to combine with operating grip, can realize crawl control, hand push-button switch 7, transfer handle valve 6, cylinder can move, side frame can pass in and out, hand leaves push-button switch 7, and side frame stops mobile immediately, fully guarantees safety.
The control gear of a kind of driving mechanism that the utility model provides has the following advantages:
1, the Pneumatic valve of control cylinder 1 adopts pressure type double gas control valve 4 in the three-position five-way, and arranges the reduction valve 3 of a band adverse current function in rodless cavity one side, in conjunction with using, produces when effectively having avoided stopping to start again later and impacts;
When 2, bimanualness, hand touch the button switch 7, the bat-handle switch of another handling handle valve 6, the side frame slippage, as emergency case, hand leaves push-button switch 7, and side frame is out of service immediately;
3, guaranteed safe enough under the reliable situation;
4, this control mode is simple, does not increase cost;
5, principle is simple, easy care.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
