Fig. 2 is the structural representation at the hydraulic-driven station of a kind of armful of tank car automatic safe protective device the utility model proposes;
Fig. 3 is the structural representation at the hydraulic-driven station of a kind of armful of tank car automatic safe protective device the utility model proposes.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model:
As shown in Figure 1-Figure 3, system of the present utility model is mainly comprised of master control system and hydraulic-driven station two parts, and embracing tank car has two big arm cylinders, on the large arm of a side therein, displacement sensor for pull rope is installed.
Preferably, this displacement sensor for pull rope is bus-type electric elements, measure length more accurately, more stable, and bus data transmission more can meet the requirement of real-time of communication.
Embracing tank car has two oil cylinder of small arms, and a forearm arm head is installed the forearm spacing approach switch of retracting therein.
Preferably, this approach switch is high temperature resistant type electric components, the harsh environment that forearm arm head temperature is high to meet, dust is many.
Controller is programmable PLC controller, is car load core component, the logic control of the collection of responsible car load data and analysis and each hydraulic pressure, electric elements.
Preferably, this controller is vehicle specific PLC, is car load center-control core component, and car load total data is by controller collection, processing, the safety protection control of last execution.Especially, this controller adopts the data communication mode of bus-type, more stable, reliable.
Preferably, YA11 is switching value electromagnetic valve, the open and close of control pump; YAP1, YAP2, YAP3, YAP4, YAP5, YAP6 are proportional quantities reversing solenoid valve, according to operating handle, control these relatively aperture sizes of valve, realize start and stop and the speed of action.
The data of the large arm displacement pickup of controller collection, controller judges according to the information of this displacement pickup the path of motion that large arm is retracted.Large arm when normal retraction, electromagnetic valve YA11 dead electricity, pump work, YAP2 simultaneously, YAP4 obtains electric, solenoid directional control valve is opened.In large arm retraction process, when the length data collecting reaches pre-set data, controller thinks that large arm will retract and put in place, and then makes YA11 obtain the electric object that reaches off-load to close hydraulic pressure cascade rotary pump by logic operation, makes YAP4 dead electricity to close one group of multiway valve.By above logic, export, after large arm will be retracted and be put in place, large arm is slowly steadily to retract by gravity substantially, even if operator's operating handle does not unclamp, also can not produce the larger pulling force large arm that fractures because pump has off-load.
In like manner, the data of the large arm displacement pickup of controller collection, controller judges according to the information of this displacement pickup the path of motion that large arm stretches out.Large arm when normally stretching out, electromagnetic valve YA11 dead electricity, pump work, YAP1 simultaneously, YAP3 obtains electric, solenoid directional control valve is opened.At large arm, stretch out process, when the length data collecting reaches pre-set data, controller thinks that large arm will stretch out and put in place, and then makes YA11 obtain the electric object that reaches off-load to close hydraulic pressure cascade rotary pump by logic operation, makes YAP3 dead electricity to close one group of multiway valve.By above logic, export, after large arm will stretch out and put in place, large arm is slowly steadily to stretch out by gravity substantially, even if operator's operating handle does not unclamp, also can not produce the larger pulling force large arm that fractures because pump has off-load.
When slag ladle will overturn, need to start forearm action.And forearm when action needs large arm to stretch out certain distance and could operate forearm, otherwise likely cause slag ladle to collide car body, cause safety misadventure.So controller is by gathering the data of large arm displacement pickup, when the data that collect reach pre-set data, controller just allows to operate forearm, otherwise forearm operation is invalid.
For preventing that forearm from fractureing, large arm must guarantee when retracting that forearm retraction puts in place, if forearm is retracted completely, when large arm is retracted, forearm can clash into car body, causes forearm to fracture.So controller judges whether forearm retracts and puts in place, the large arm of can retracting when SQ1 has signal, otherwise the large arm exercise void of retracting by gathering the signal of approach switch SQ1.
For convenience of operator, grasp in real time whole vehicle state data, controller is delivered to monitor display by bus all data.This telltale is that construction machinery and equipment is special-purpose, except the input/output signal for monitored control system, also can, by bus network to modules sending controling instruction, can realize complete signal monitoring, control and warning function.
In addition,, due to the variety of large arm position probing mode, following several modes can reach goal of the invention equally: 1, approach switch detects large arm position; 2, the large arm of infrared detection position; 3, the large arm of laser detection position.
Key problem in technology point of the present invention is mainly: 1, by the movement position of the large arm of bus-type pulling cord displacement sensor, and 2, large arm stretches out that security logic is controlled and the interlocked relationship of large arm retraction safety guard-safeguard logic control and forearm position; 3, the interlocked relationship of forearm action and large arm position; 4, man-machine interactive system, the real-time dynamic monitoring of car load data, reminds driver safety operation in time.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all in protection domain of the present utility model.
