Description
Technical field：
The utility model is related to a kind of revolution hydraulic circuits of rotary drilling rig.
Background technology：
For rotary drilling rig when doing upper-part rotation action, getting on the bus rotates that (chassis is relative to ground relative to chassis
Face is motionless.It gets on the bus and is connect with the outer ring of pivoting support, chassis bull gear is connected with the inner ring of pivoting support).Its principle is：It returns
Turn speed reducer lower end sliding tooth to be meshed with chassis bull gear, hydraulic motor output shaft is matched with speed reducer.Work as hydraulic motor
Drive speed reducer lower end sliding tooth around the relative rotation of chassis bull gear when rotation, due to the pedestal and drilling machine of rotary reducer
Get on the bus and be connected together, thus get on the bus can around the rotation of chassis bull gear (chassis bull gear connect with H framves, relative to
Ground is motionless).In the prior art, hydraulic circuit is turned round as shown in Fig. 2, this oil circuit connection is fairly simple, control mode
Fairly simple, when drilling machine, which is turned back to certain angle, to be needed to stop, moment of stopping is not delayed buffering, due to inertia of getting on the bus yet
Very big and no delay buffering, speed reducer lower end sliding tooth and chassis bull gear collision impact are very big, over time under speed reducer
End sliding tooth and chassis bull gear can all have damage, be needed replacing when serious.
Utility model content：
The utility model provides a kind of revolution hydraulic circuit of rotary drilling rig, which returns
The moment for turning to stop increases delay and buffering, effectively slows down between chassis bull gear and rotary reducer lower end sliding tooth
Impact force has effectively delayed being damaged caused by impact force between rotary reducer lower end sliding tooth and chassis bull gear, has prolonged
The service life for having grown rotary reducer lower end sliding tooth and chassis bull gear solves existing skill suitable for being widely used to promote
The problem of art.
Used technical solution is the utility model to solve above-mentioned technical problem：
A kind of revolution hydraulic circuit of rotary drilling rig, including rotary reducer brake, the connection of rotary reducer brake
Rotary fluid motor, the oil inlet end of the rotary reducer brake are connected with the oil outlet end of a delay pilot operated valve device, and be delayed hydraulic control
The oil inlet end of valve is connected with single-revolution pilot solenoid valve, turns round the oil inlet end connection guide's oil circuit of pilot solenoid valve；The revolution
Two hydraulic fluid ports of hydraulic motor are separately connected two oil inlet ends of single-revolution trimmer valve, and two oil outlet ends of rotary buffering valve are separately connected one
Two oil inlet ends of working connection multi-way valve；The aperture of the oil return damping hole of the delay pilot operated valve device is 0.6mm.
The model Rexroth 0571470304z0001A of the rotary buffering valve.
The guide's oil circuit oil pressure P ≈ 3.5MP.
Using the above structure, which increases delay pilot operated valve device, and more to the utility model
Rotary buffering valve has been changed, buffering and delay are increased when stopping rotating to moment of getting on the bus, bull gear has effectively been slowed down and subtracts with revolution
Impact force between the sliding tooth of fast machine lower end, has effectively delayed between rotary reducer lower end sliding tooth and bull gear because of impact force
Caused by damage, rotary reducer lower end sliding tooth and the service life of bull gear are extended, suitable for being widely used to promote.
Description of the drawings：
Fig. 1 is the oil circuit figure of the utility model.
Fig. 2 is oil circuit figure in the prior art.
In figure, 1 rotary reducer brake, 2 rotary fluid motors, 3 delay pilot operated valve devices, 4 revolution pilot solenoid valves, 5 times
Turn trimmer valve, 6 working connection multi-way valves.
Specific implementation mode：
In order to clarify the technical characteristics of the invention, below by specific implementation mode, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in figs. 1-2, the revolution hydraulic circuit of a kind of rotary drilling rig, including rotary reducer brake 1, revolution subtracts
Fast brake 1 connects rotary fluid motor 2, and the oil inlet end of the rotary reducer brake 1 is connected with a delay pilot operated valve device 3
Oil outlet end, the oil inlet end of delay pilot operated valve device 3 is connected with single-revolution pilot solenoid valve 4, and the oil inlet end of revolution pilot solenoid valve 4 connects
Connect guide's oil circuit；Two hydraulic fluid ports of the rotary fluid motor 2 are separately connected two oil inlet ends of single-revolution trimmer valve 5, revolution buffering
Two oil outlet ends of valve 5 are separately connected two oil inlet ends of a working connection multi-way valve 6；The oil return damping hole of the delay pilot operated valve device 3
Aperture is 0.6mm.
The model Rexroth 0571470304z0001A of 5 valves of the revolution buffering.
The guide's oil circuit oil pressure P ≈ 3.5MP.
Using the revolution hydraulic circuit of the rotary drilling rig of the utility model, when needing drilling machine upper-part rotation, to operate and drive
It sails interior hydraulic control control crank and pins the automatically controlled button on this hydraulic controlled operation handle simultaneously, first conductive magnetism is turned round after pressing automatically controlled button
Valve 4 can be powered, and so that guide oil is passed sequentially through revolution pilot solenoid valve 4 and delay pilot operated valve device 3 and enter rotary reducer brake 1
Oil inlet end, open rotary reducer brake 1.While pinning automatically controlled button, operation hydraulic control control crank of turning left or turn right
The meeting of working connection multi-way valve 6 fuel feeding, fluid make rotary fluid motor 2 work afterwards, and rotary reducer rotation is driven (to drive rotation of getting on the bus
Turn).When being turned back to certain angle and needing parking, hydraulic control control crank Hui Zhongwei in driver's cabin, at this time rotary buffering valve 5 are operated
First play buffering；Delay pilot operated valve device 3 goes back to middle position so that enters the hydraulic oil in rotary reducer brake 1 by 0.6mm's
Damping hole returns to fuel tank, plays good time-lag action.
Above-mentioned specific implementation mode cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
