The specific embodiment
Embodiment one, in Fig. 1, drives in the hydraulic efficiency pressure system of HM Hydraulic Motor 3 and operator's compartment independently that oil pump 6 is connected, and hydraulic efficiency pressure system connects and drives HM Hydraulic Motor 3, and the compressor 4 of interior environment system passes through elasticity drive coupling 13 and is connected with 3 of HM Hydraulic Motor of driving.Drive HM Hydraulic Motor 3 and pass through oil inlet 10 is connected the hydraulic efficiency pressure system in the center steering body 1 with oil return pipe 11 oil pipe, center steering body 1 is connected load 2 by former load oil inlet 8 with former load oil return pipe 9.During work, the circulation of hydraulic oil is a two-way: the one tunnel be hydraulic oil by oil pump 6 through center steering body 1, former load oil inlet 8, load 2, former load oil return pipe 9, get back to fuel tank 5 through center steering body 1, make load 2 normal operation; Another road be hydraulic oil by oil pump 6 through center steering body 1, oil inlet 10, drive HM Hydraulic Motor 3, oil return pipe 11, former load oil return pipe 9, get back to fuel tank 5 through center steering body 1.Drive the compressor 4 that HM Hydraulic Motor 3 drives interior environment systems and rotate, oil inlet 10 is by pump fuel feed independently.
Embodiment two, in Fig. 2, driving HM Hydraulic Motor 3 is connected with being connected to of hydraulic efficiency pressure system of operator's compartment, the compressor 4 of interior environment system is connected with 3 of HM Hydraulic Motor of driving by elasticity drive coupling 13, drive HM Hydraulic Motor 3 and ball valve 12 ' polyphone back with ball valve 12 and connect, and then be connected in the former load oil return pipe 9 of hydraulic efficiency pressure system.During work, ball valve 12 is closed, ball valve 12 ' is opened, at this moment, the trend of oil circuit is that hydraulic oil enters former load oil inlet 8 by oil pump 6 through center steering body 1, load 2, former load oil return pipe 9, drive HM Hydraulic Motor 3, ball valve 12 ', get back to fuel tank 5 through center steering body 1, hydraulic flow drives compressor 4 work that HM Hydraulic Motor (3) then drives interior environment system.
Embodiment three, in Fig. 3, drive being connected to and downlink connection of hydraulic efficiency pressure system of HM Hydraulic Motor 3 and operator's compartment.The compressor 4 of interior environment system connects driving HM Hydraulic Motor 3 by elasticity drive coupling 13, drive former load oil inlet 8 and former load oil return pipe 9 and downlink connection on HM Hydraulic Motor 3 and governor valve 15 polyphone backs and the center steering body 1, polyphone sequence valve 14 on the former load oil inlet 8.During work, sequence valve 14 and governor valve 15 are transferred to correct position, high pressure oil enters former load oil inlet 8, enters through governor valve 15 and drives HM Hydraulic Motor 3, thereafter again through former load oil return pipe 9 oil returns, drives 4 rotations of 3 drive compressors of HM Hydraulic Motor.
Embodiment four, in Fig. 4, this device had increased integrated distributing valve 7 before driving HM Hydraulic Motor 3, thereby make interior environment system easier for installation, more reliable and more stable, integrated distributing valve 7 makes the system pressure equilibrium by the flow of regulating high pressure oil, make and drive HM Hydraulic Motor 3 stabilizations of speed, guarantee that whole interior environment system can work all the time under the pressure of equilibrium, bear whole hydraulic system pressure, make the fixed difficult problem of rotary speed unstabilization thereby solved driving HM Hydraulic Motor 3.Drive HM Hydraulic Motor 3 and be connected with hydraulic efficiency pressure system by integrated distributing valve 7, its high pressure oil circulating oil path is: oil pump 6, center steering body 1, former load oil inlet 8, load 2, former load oil return pipe 9, integrated distributing valve 7, drive HM Hydraulic Motor oil inlet 16, drive HM Hydraulic Motor 3, integrated distributing valve oil inlet 17, integrated distributing valve 7, integrated distributing valve oil return pipe 18, center steering body 1, fuel tank 5.Drive HM Hydraulic Motor 3 and be connected by 13 of elasticity drive couplings, drive compressor 4 normal operation with the compressor 4 of interior environment system.This connection mode is to utilize the spill pressure of operator's compartment hydraulic efficiency pressure system to carry out work, thereby do not influence the normal operation of construction machinery and equipment, integrated distributing valve 7 connects former load oil return pipe and utilized spill pressure to make 3 work of driving HM Hydraulic Motor in 9 minutes behind the oil, thereby drive the compressor operation of interior environment system, make the interior environment system normal operation.
