Abstract
The invention relates to a gas circuit control device for forbidding a tipping bucket. The device comprises a main pneumatic parking brake loop and a pneumatic control loop, wherein the main pneumatic parking brake loop is formed by sequentially connecting a gasholder, a relay valve and a pneumatic brake via a gas pipe; the pneumatic control loop is formed by sequentially connecting the gasholder, a forward switch, a travel switch and the relay valve via the gas pipe. The device is controlled by gas circuit; the operation is safe and reliable; thus the safety performance of the tipping bucket is greatly improved.
Description
Technical field
The invention belongs to the forbidden control gas path device of a kind of safe tipping bucket, particularly relate to a kind of Absorbable organic halogens and control the motor-tilter control gas path device forbidden when unloaded of cargo.
Background technology
In present society, have the automobile of various purposes, what have realizes Self-tipping goods by lifting tipping bucket, and this process exists some safety hazard, therefore controls that tipping bucket is forbidden just seems extremely important.Just current, existing motor-tilter, when unloaded of cargo, disposablely all can not complete unloading, vehicle body is needed suitably to move forward a segment distance, in the process of this movement, there is very high requirement to the motion and standstill controlling automobile, very easily cause safety misadventure.In addition, in the process by control circui motor-tilter unloaded of cargo, driver, after completing unloaded of cargo, forgets and makes skip bucket reset, continues to move ahead to make vehicle body lack of equilibrium, thus causes safety misadventure.
Summary of the invention
This uses novel object to be to overcome prior art deficiency, provides that a kind of gas circuit controls, safe and reliable, the easy to operate forbidden control gas path device of tipping bucket.
The technical solution used in the present invention is:
The forbidden control gas path device of tipping bucket, comprise pneumatic parking brake major loop and Pneumatic control circuit, storage tank, relay valve, aerodynamic brake are connected in sequence by tracheae by described pneumatic parking brake major loop, and storage tank, the switch that moves ahead, travel switch, relay valve are connected in sequence by tracheae by described Pneumatic control circuit.
Further, the switch ends that the moves ahead parking brake switch in parallel in described Pneumatic control circuit.
The invention has the beneficial effects as follows:
(1) the forbidden and current state that controlled by travel switch of the present invention, is prevented automobile from advancing when tipping bucket does not reset, eliminates the potential safety hazard that automobile brings because tipping bucket does not reset.
(2) the present invention can also control that automobile rises at tipping bucket by the switch that moves ahead, goods fail complete discharge, automobile can be moved ahead a segment distance, goods can be unloaded completely.
(3) the present invention adopts gas circuit to control, safety of operation is reliable, the process of unloaded of cargo is become and is simply convenient to control, and can ensure safety fully, and solve some because neglecting the possible risk brought, substantially increase the safety performance of tip lorry.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the forbidden control gas path device of tipping bucket.
In accompanying drawing, 1-storage tank, 2-relay valve, 3-aerodynamic brake, 4-travel switch, 5-parking brake switch, 6-moves ahead switch.
Detailed description of the invention
Be described in further detail this use is novel below by concrete case study on implementation.
As shown in Figure 1, the forbidden control gas path device of a kind of tipping bucket, comprises pneumatic parking brake major loop and Pneumatic control circuit, and storage tank 1, relay valve 2, aerodynamic brake 3 are connected in sequence by tracheae by described pneumatic parking brake major loop.Storage tank 1 is at body bottom, and relay valve 2 is arranged on vehicle body, and aerodynamic brake 3 is arranged on wheel nave.When relay valve 2 is opened, the pressure gas in storage tank 1 will enter in aerodynamic brake 3, aerodynamic brake 3 action, and automobile is in forbidden state; When relay valve 2 cuts out, the pressure gas in storage tank 1 can not enter in aerodynamic brake 3, and aerodynamic brake 3 is failure to actuate.Relay valve 2 opens and closes and is controlled by Pneumatic control circuit.
Storage tank 1, the switch 6 that moves ahead, travel switch 4, relay valve 2 are connected in sequence by tracheae by described Pneumatic control circuit, switch 6 two ends that the move ahead parking brake switch 5 in parallel in described Pneumatic control circuit.Move ahead switch 6 and parking brake switch 5 is all arranged in operator's compartment, and travel switch 4 is arranged on automobile chassis frame, is positioned at below automobile tipping bucket.
Its control principle is as follows: the pressure gas in storage tank 1 is via ventilation flue, and a part is transferred to the switch 6 that moves ahead, and when current line switch 6 is opened, gas enters in travel switch 4.When automobile tipping bucket fills goods depression stroke switch 4, travel switch 4 cuts out, and gas cannot enter relay valve 2, and relay valve 2 is in closed condition, and pneumatic parking brake major loop can not conducting, and aerodynamic brake 3 is failure to actuate, and automobile is in current state; When automobile tipping bucket wants unloaded of cargo, automobile tipping bucket rises, and travel switch 4 conducting, gas enters relay valve 2, and relay valve 2 is opened, the conducting of pneumatic parking brake major loop, and aerodynamic brake 3 action, automobile is in forbidden state.
Motor-tilter, when unloaded of cargo, disposablely all can not complete unloading, and need in the process of unloaded of cargo, vehicle body suitably moves forward a segment distance.The effect of switch 6 of moving ahead just be used to automobile tipping bucket rise be in forbidden state time, control relay valve 2 action, make forbidden state change current state into, its principle of work is as follows:
When unloaded of cargo, when the switch 6 that moves ahead is opened, air-flow passes through smoothly, flow into travel switch 4 (travel switch 4 is conductings when tipping bucket rises), then air-flow flows into relay valve 2 by travel switch 4, the conducting of pneumatic parking brake major loop, aerodynamic brake 3 action, automobile is in forbidden state.When in the process in unloaded of cargo, when vehicle body needs suitably to move forward a segment distance, as long as chaufeur closes the switch 6 that moves ahead, whole piece control loop is obstructed, relay valve 2 is in closed condition, and pneumatic parking brake major loop can not conducting, and aerodynamic brake 3 is failure to actuate, automobile is in current state, and now chaufeur can drive a car and move ahead.
: when current line switch 6 breaks down or needs repairing and changes can be controlled by operation parking brake switch 5, guarantee that security of system is reliable in the object of switch 6 two ends that move ahead parking brake switch 5 in parallel.
