Description
Technical field
The present invention relates to a kind of control system, be specifically related to a kind of quarry tipper jogging control system.
Background technology
Mine truck is mining transport trolley, belongs to one of mining equipment, and mine truck is because its car body is roomy, and the load carrying ability height is mainly used in the ore in mine and the short-distance transportation of other bulk cargo.In mine truck, vehicle transmission jogging device generally all is housed, it mainly acts on is that vehicle makes car retardation when bend or descending.When automobile during at bend or descent run, need Reduced Speed Now, because the mine truck total mass ratio is bigger, when Reduced Speed Now, just need overcome bigger inertia, automobile is lowered moving velocity in the short period of time.Under this operating mode, the conventional truck mode is a chaufeur control brake system, and the vehicle shift to low gear is travelled, and long-time continuous is used and will be caused the brake system temperature to rise, and braking potential descends, thereby the brake failure phenomenon occurs.
At above-mentioned deficiency, along with constantly improving and development of science and technology, hydrodynamic retarder is by a large amount of integrated car transmissions design fields that has been installed in, and the effect that hydrodynamic retarder produces when the vehicle low gear is the most obvious.Its structure of hydrodynamic retarder of generally using generally is made up of main parts size such as output shaft, hydrodynamic retarder rotor, blade, retarder housing, control system operating mechanisms at present.Before the jogging control system is not unlocked, the rotor of hydrodynamic retarder rotates with the rotating speed of turbine output all the time, when operating mechanism will be walked or drive slowly the control system unlatching, control cock and valve body assembly are opened, the hydraulic oil that has certain pressure enters in the retarder housing, this moment, the cavity of hydrodynamic retarder peritrochanteric was filled with hydraulic transmission oil, hydraulic oil with certain viscosity is to the certain resistance of blade on the fluid power retarder rotor, limit its rotative speed, thereby limited the moving velocity of car load.
Yet, existing its control system of hydrodynamic retarder technology is traditional manipulator shank type operating mode and hydraulic ram executive mode, for for the quarry tipper of continuous descending and negotiation of bends, need this moment the attention of chaufeur height to observe the road conditions of travelling, and the Stroke Control etc. of walking or drive slowly accurately, traditional manipulator shank type jogging action need chaufeur manually spurs or promotes control handle, the attention that will certainly disperse chaufeur like this, and operation inconvenience, jogging Stroke Control precision is not enough, causes potential safety hazard; And for the hydraulic ram executive mode, though can remedy the deficiency of manipulator shank type operating mode, its complex structure, parts are more in the implementation, occur various faults in real work easily, cause maintenance cost higher.
Summary of the invention
The object of the invention provides a kind of quarry tipper jogging control system, uses this device, has solved the deficiency that exists in the control system of in the past walking or drive slowly, and has improved the accuracy and the safety of quarry tipper jogging control operation.
For achieving the above object, the technical solution used in the present invention is: a kind of quarry tipper jogging control system, comprise that one is arranged at the jogging control assembly on the quarry tipper, described jogging control assembly is provided with a jogging actuating unit and a fixed support, described jogging actuating unit is connected with fixed support, described fixed support is connected on the quarry tipper through bolt, described jogging actuating unit drives change speed gear box jogging valve rod, cooperates with described jogging actuating unit also to be provided with the jogging master cock.
In the technique scheme, described jogging master cock can be installed on the central control board on chaufeur right side in the mine truck operator's compartment, is convenient to chaufeur and controls, and jogging control assembly is installed on the vehicle, power on/off by jogging master cock control assembly realizes the action of jogging actuating unit.Be respectively equipped with jogging actuating unit and fixed support on the jogging control assembly, fixed support is connected with quarry tipper, and the jogging actuating unit is fixed on the fixed support.This device when chaufeur need be carried out jogging control, is pressed the jogging master cock on the instrument carrier panel in the operator's compartment in use, the energising of switch control jogging control assembly, promote the work of jogging control executing mechanism, and then make change speed gear box jogging valve rod setting in motion, finishing jogging control.
Further technical scheme, described jogging actuating unit comprises a housing, be provided with motor in it, described motor output shaft is connected with push rod through speed reduction gearing, described push rod outer end and described change speed gear box jogging valve rod are conflicted, the end of the nearly push rod of described housing outer end is provided with stop gear, also is provided with power-transfer clutch and stop mechanism in the described housing.Described motor power on/off is by the control of jogging master cock, after pressing the jogging master cock, electrical power rotates, driving push rod through the speed reduction gearing transmission stretches out, push rod stretches out conflict change speed gear box jogging valve rod, make the action of change speed gear box jogging valve rod realize jogging control, power-transfer clutch is used to disconnect the interlock of speed reduction gearing and push rod, stop mechanism is used for braking motor, stop mechanism cooperates with parts such as in-to-in fixed type limit switch, power-transfer clutchs, can the position of push rod is fixing arbitrarily in its stroke range, stop gear is used to limit push rod, and anti-throw-out lever stretches out housing.
Further technical scheme, described jogging master cock is a wane type switch.
Further technical scheme is positioned at power-transfer clutch on the described jogging actuating unit and the push rod end is provided with built-in switch.Described built-in switch can in time be controlled the power on/off of motor, realizes cutting off functions such as power and overload protection.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. because the present invention controls assembly by jogging is set on quarry tipper, through jogging master cock control jogging assembly break-make, and then control jogging actuating unit action, control the action of change speed gear box jogging valve rod, implement jogging control, seem more convenience and accurately of jogging operation as compared with the past, and chaufeur only need be controlled the jogging master cock, need not to take sb's mind off sth, improved the safety of driving;
2. the jogging actuating unit is fixed on the fixed support among the present invention, and fixed support is connected with quarry tipper through bolt, and it is comparatively convenient to install, and the actuating unit installation site scalable that makes and walk or drive slowly satisfies different operatings needs;
3. power-transfer clutch and push rod end of travel have the built-in switch of protection in the electronic actuating system, can in time control the power on/off of motor, realize cutting off functions such as power and overload protection;
4. the present invention is simple in structure, and is easy to use, and cheap, is fit to promote the use of.
