Description
Technical field
The utility model relates to a kind of mining construction machinery and equipment, the explosion-proof driven Biodge device of particularly a kind of multifunction mine construction machinery and equipment.
Background technology
Mining engineering machinery walking system also need have the ability of braking during standstill, emergency braking and service braking usually except that needing bigger weight capacity and power-handling capability.Consider the safety requirements of mining construction machinery and equipment, brake system requires to adopt wet braking, and wherein emergency braking requires to adopt brake application by spring hydraulic pressure delivery mode.At present, the oil-immersed multi-disk brake that the driven bridge of mining engineering machinery walking system adopts adopts the partial installation form more, and many have braking during standstill and emergency braking function.Therefore, drg is installed inconvenience, and the service braking function can't satisfy the operating needs of mining construction machinery and equipment all by the fluid power system realization of drive axle under some heavily loaded high-revolving operating mode.If add a cover service braking system in addition at driven bridge, can realize the service braking requirement, but difficult arrangement, design difficulty are big, additional service braking system may influence the service life of former drg because of the strained condition that changes former drg.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, the driven Biodge device of a kind of multifunctional anti-explosion has been proposed, make the driven bridge of mining engineering machinery walking system can satisfy braking during standstill and emergency braking requirement, also can be competent at the service brake requirement, simultaneously compact conformation is easy for installation and have high service life, thereby improve the carrying and the deceleration and stopping performance of complete machine, simplified structure design, cost-cutting.
The technical problems to be solved in the utility model is achieved through the following technical solutions, the driven Biodge device of a kind of multifunctional anti-explosion, comprise wheel rim, the load-bearing axle, be connected by the load-bearing flange between wheel rim and the load-bearing axle, on the load-bearing axle drg is housed, drg comprises braking drive organ and by the brake strip moving plate, the brake actuator that the brake strip stator constitutes, braking drive organ comprises that hydraulic pressure discharges oil cylinder, the top that hydraulic pressure discharges oil cylinder is provided with annular platen, the back side of platen is provided with some braking springs, the braking spring evenly is provided with ringwise along the card of platen, be characterized in: between per two adjacent braking springs, all be provided with the service braking oil cylinder, have the through hole that cooperates with the piston rod of service braking oil cylinder on the platen, be provided with floating platen between the front of platen and the brake actuator.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, the piston rod retracing spring is housed in the cylinder body of service braking oil cylinder.
Driven walking operating mode
During mining engineering machinery walking, driven bridge need guarantee that each brake system all is in open mode.Therefore, discharge oil cylinder to hydraulic pressure and feed pressure oil, simultaneously the service braking oil cylinder is connect the oil circuit pressure release, make hydraulic pressure discharge the driving lower compression braking spring of the platen of oil cylinder at hydraulic fluid pressure, simultaneously the service braking oil cylinder piston under the effect of retracing spring to returning, brake strip moving plate, brake strip stator are loosened, and are in open mode.Driven bridge wheel drives the load-bearing flange and the load-bearing axle rotates.
The service braking operating mode
Oil-immersed multi-disk brake adopts the mode of operation of hydraulic braking during service braking.During service braking, keep discharging oil cylinder to hydraulic pressure and feed pressure oil, begin simultaneously to feed pressure oil in the service braking oil cylinder, make the operating brake cylinder piston push away floating platen, brake strip moving plate, brake strip stator are compacted, are in braking mode.At this moment, the big young pathbreaker of lock torque increases gradually with the increase of service braking oil cylinder working-pressure, and adjustable, thereby realizes service braking.
The emergency braking operating mode
Emergency braking be provided with purpose be to guarantee when service braking under faults such as system's decompression malfunctioning or when being in an emergency vehicle can in time realize braking.Hydraulic pressure is discharged the oil cylinder pressure release, no matter whether be connected with high pressure oil in the service braking oil cylinder this moment, promptly no matter whether the service braking function lost efficacy, it is compacted with brake strip moving plate, brake strip stator under the promotion of braking spring that hydraulic pressure discharges the oil cylinder platen, the instantaneous braking mode that transforms to of drg; Realize emergency braking.Because the heat-dissipating space of brake plate group is big, heat-sinking capability is strong, can not produce big temperature rise or influence its service life.
The stopping brake operating mode
During the stopping brake operating mode, stoppage of vehicle is in the original place, under the state of engine off, hydraulic pressure discharges oil cylinder and service braking road that oil cylinder is taken over loses pressure simultaneously, hydraulic pressure discharges the oil cylinder platen and under the promotion of braking spring brake strip moving plate, brake strip stator is compressed, and this moment, drg was in braking mode.
The utility model is compared with existing mechanism, and is simple and compact for structure, and the function that can satisfy driven walking, service braking, emergency braking and stopping brake simultaneously can guarantee long service life again.When optimizing mining construction machinery and equipment drive system performance, improve the carrying and the deceleration and stopping performance of complete machine, simplify the structure, reduced cost.
