Abstract
A hydraulic rotary system of an excavator with a buffer device is characterized in that a rotary motor is provided with a brake, and the brake is connected with a brake control electromagnetic valve through a lead; one oil pipe of the rotary motor is respectively connected with one oil pipe A of the buffering pressure-limiting oil replenishing valve and one oil pipe of the anti-rebound valve through a tee; an oil pipe A on the buffering pressure limiting oil supplementing valve is connected with one oil pipe of the rotary operating valve; the other oil pipe of the rotary operating valve is respectively connected with the buffer pressure limiting oil supplementing valve and the other oil pipe of the rotary motor through a tee joint, and the oil pipe on the rotary motor is connected with the other oil pipe of the anti-rebound valve; the anti-rebound valve is respectively connected with one pole of the control valve and one pole of the electromagnetic valve through leads; the other pole of the control valve is connected with the other pole of the electromagnetic valve through a lead. The utility model discloses the gyration is more powerful, also is difficult to cause slewing motor, slewing bearing to break the tooth.
Description
Technical Field
The utility model relates to an excavator hydraulic pressure swing system especially relates to a take buffer's excavator hydraulic pressure swing system.
Background
The hydraulic rotation system of the excavator is the core of the excavator, namely the upper platform can rotate in any angle and forward and reverse rotation directions relative to the lower frame through the work of elements such as a hydraulic rotation mechanism, a rotation gear ring, a central rotation joint and the like. The hydraulic motor and the rotary speed reducer are key components; the existing rotary hydraulic system has weak rotary force and is easy to cause the tooth breakage of a rotary bearing of a rotary motor.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough among the prior art to a take buffer's excavator hydraulic pressure swing system is provided.
A hydraulic rotary system with a buffer device for an excavator comprises a rotary motor, a brake control solenoid valve, a buffer pressure-limiting oil supplementing valve, an anti-rebound valve, a rotary operating valve, a control valve and a solenoid valve; the rotary motor is provided with a brake, and the brake is connected with a brake control electromagnetic valve through a lead; one oil pipe of the rotary motor is respectively connected with one oil pipe A of the buffering pressure-limiting oil replenishing valve and one oil pipe of the anti-rebound valve through a tee; an oil pipe A on the buffering pressure limiting oil supplementing valve is connected with one oil pipe of the rotary operating valve; the other oil pipe of the rotary operating valve is respectively connected with the buffer pressure limiting oil supplementing valve and the other oil pipe of the rotary motor through a tee joint, and the oil pipe on the rotary motor is connected with the other oil pipe of the anti-rebound valve; the anti-rebound valve is respectively connected with one pole of the control valve and one pole of the electromagnetic valve through leads; the other pole of the control valve is connected with the other pole of the electromagnetic valve through a lead.
The beneficial effect of adopting above-mentioned technical scheme is:
the utility model discloses the gyration is more powerful, also is difficult to cause slewing motor, slewing bearing to break the tooth.
