Abstract
The utility model relates to a dump truck expired braking control device which is composed of a parking brake valve (1), a fast exhausting valve (3) and a brake cylinder brake chamber (4). The utility model is characterized in that a double-location and three-way electromagnetic valve and a control system (2) are connected between the parking brake valve (1) and the fast exhausting valve (3). Accordingly, collision accidents which are caused by that carriages are not put down are eliminated, and the utility model can also satisfy the requirement of the special operating condition of running with unloading. The utility model has the advantage of simple structure and practicality and is especially suitable for dump trucks to control expiration.
Description
Affiliated technical field
The utility model relates to a kind of dumping truck braking force control system, a kind of especially dumping truck braking force control system of dying.
Background technology
As everyone knows, during the dumping truck unloading operation, because warning and restriction starting travel controlling system when self lacking the compartment and being in the lifting state, add factors such as chaufeur is off one's guard, joy riding, the grave accidents such as disconnected wind, water lines, communication and power cable of blowing that cause take place frequently because drive that the dumping truck do not put down the compartment travels so cause chaufeur, have brought tremendous loss and inconvenience for people's lives and properties and productive life.
Summary of the invention
The purpose of this utility model is: provide a kind of failure-free to report to the police and the braking automatic control device of dying.This device can be implemented to report to the police and the braking of dying to vehicle when artificial and mechanical electric failure and other reasons cause the completion of discharge trunk not put down automatically.The utility model realizes enough that simultaneously vehicle travels on one side, Yi Bian carry out discharged special operation condition needs.
The purpose of this utility model is achieved in that a kind of self-unloading braking automatic control device of dying, form by braking during standstill valve (1), rapid release valve (3), brake cylinder compressed air brake cylinder (4), it is characterized in that being connected two-bit triplet electromagnetic valve and control system (2) between described braking during standstill valve (1) and the rapid release valve (3).
An embodiment of the present utility model is: two-bit triplet electromagnetic valve and control system (2) are to be connected with slug relay KT open contact by digital display type rotor switch SB, the KT of slug relay normally closed contact and proximity switch K1 and two-bit triplet electromagnetic valve G (2) composition that is connected in series, its P end of two-bit triplet electromagnetic valve G connects braking during standstill valve (1), the logical atmosphere of A end, the B end connects rapid release valve (3), the warning that two logical three-position electromagnetic valve G parallel connections one are connected in parallel the back and are composed in series near K switch 2 by warning indicator lamp LD and buzzer phone FMQ.
Adopt the vehicle of split brake system not have rapid release valve, the pipe end of the P end connection braking during standstill valve (1) of two-bit triplet solenoid directional control valve G can being given vent to anger, the B end connects brake cylinder air inlet pipe end, the logical atmosphere of A end.
The beneficial effects of the utility model are: because to lifting state and the warning in compartment and die to brake and implemented automatic guidance, eliminated because of not putting down compartment start to walk the to travel generation of the scratching accident that causes.Realized that simultaneously vehicle travels on one side, on one side discharged special operation condition needs.This design makes full use of original parts and system, and is simple in structure, effective, practical.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a concrete structure scheme drawing of the present utility model.
Fig. 2 is electrical control figure of the present utility model:
1, braking during standstill valve 2, two-bit triplet solenoid directional control valve and control system 3, rapid release valve 4, brake cylinder compressed air brake cylinder
SB: digital display type rotor switch KT: the K1 of slug relay, K2: near switch LD:
Warning indicator lamp FMQ: buzzer phone
The specific embodiment
Among the embodiment shown in the drawings, two-bit triplet solenoid directional control valve G employing outage conducting type, its P end connects braking during standstill valve (1) freeing pipe, B end connection rapid release valve (3) air inlet pipe, the logical atmosphere of A end; Select the outage open type for use near K switch 1, K2, be connected with the slug relay normally closed contact near K switch 1 one ends, the other end is connected with two-bit triplet solenoid directional control valve G.Warning indicator lamp LD and buzzer phone FMQ are connected in parallel, and connect then with near K switch 2.
The concrete working process of present embodiment is:
Be positioned at elevating ram near K switch 1, K2; Digital display type rotor switch SB is positioned on the facia board, is convenient to driver's observation and operation; The KT of slug relay places in the operator's compartment; Warning indicator lamp LD is positioned on the instrument carrier panel, and figure can adopt a compartment to be in the dumping truck scheme drawing of lifting state; Buzzer phone FMQ is positioned at operator's compartment.
1, non-special operation condition operation: the KT of slug relay normally closed contact closure, near K switch 1 open contact closure, solenoid directional control valve G (2) energising, its P end ends, and A, B hold conducting and communicate with the inlet end of rapid release valve (3), and vehicle implements to die braking.Near K switch 2 open contact closures, warning indicator lamp LD and buzzer phone FMQ report to the police simultaneously.When the compartment is fallen on the vehicle frame fully, open contact near K switch 1, K2 disconnects, warning indicator lamp LD and buzzer phone FMQ outage, solenoid directional control valve G (2) outage simultaneously, its PB end conducting, unclamp braking during standstill valve (1) this moment, pressurized air is led to rapid release valve (3) and brake cylinder (4) through change-over valve G (2), and the braking of dying is removed.
2, special operation condition operation: chaufeur is according to the operating mode needs, by rotor switch SB the normally closed contact turnoff time of the KT of slug relay is set, the KT of slug relay normally closed contact disconnects, disconnect near K switch 1 normally closed contact, solenoid directional control valve G (2) outage, its PB end conducting is Yi Bian then vehicle is realized travelling, Yi Bian carry out the lifting unloading; Near K switch 2 normally closed contact closures, warning indicator lamp LD and buzzer phone FMQ report to the police simultaneously.If the time that the KT of slug relay sets is shorter than the field operation time, chaufeur can be according to the field operation situation, the turnoff time of the KT of proper extension slug relay normally closed contact.After the time that the KT of slug relay sets arrives, its normally closed contact closure, if the compartment is in the lifting state, then near the open contact closure of K switch 1, solenoid directional control valve G (2) switches on, vehicle implements to die braking.
Claims (4)
