Detailed description of the invention
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to being described below in detail according to the rotary drilling rig the utility model proposes.
As shown in Figures 4 and 5, the rotary drilling rig that the utility model provides comprises engine assembly 20, turret assembly 30, master winch assembly 40, driver's cabin assembly 50, diesel fuel tanks assembly 60 and heat radiator assembly 70.The said equipment is all laid on the chassis 80 of rotary drilling rig, in the air outlet direction of heat radiator assembly 70, leaves and is beneficial to the gap 90 of discharging hot blast.The hot blast that heat radiator assembly 70 is discharged is discharged by gap 90, has promoted the heat radiation of rotary drilling rig.
Particularly, engine assembly 20 is laid in the afterbody on chassis 80.Turret assembly 30, master winch assembly 40, driver's cabin assembly 50, diesel fuel tanks assembly 60 and heat radiator assembly 70 are lined up two rows and are located at the same side of engine assembly 20, wherein, turret assembly 30 is corresponding with the output of engine assembly 20 with master winch assembly 40, and driver's cabin assembly 50, diesel fuel tanks assembly 60 and heat radiator assembly 70 are corresponding with the power end of engine assembly 20.Concrete, heat radiator assembly 70 is between driver's cabin assembly 50 and diesel fuel tanks assembly 60, and diesel fuel tanks assembly 60 is between heat radiator assembly 70 and engine assembly 20, and master winch assembly 40 is between turret assembly 30 and engine assembly 20.
Further, turret assembly 30 have girder 31 and with the integrated reinforcing rib 32 of girder 31.Reinforcing rib 32 is near engine assembly 20, the end face of reinforcing rib 32 and girder 31 are inclined-plane near the side of reinforcing rib 32, between the inclined-plane of girder 31 and master winch assembly 40, form the gap 90 of V-type, the height that the inclined-plane of reinforcing rib 32 makes reinforcing rib 32 by the one end near girder 31 to reducing gradually away from one end of girder 31.
In the present embodiment, in order to reduce the area on chassis 80, master winch assembly 40 is as much as possible near girder 31, now, between the inclined-plane of girder 31 and master winch assembly 40 lateral area in the V-type gap 90 of formation be substantially equal to heat radiator assembly 70 air outlet area 3/5.Understandably, the in the situation that of permission in 80 spaces, chassis, the distance between master winch assembly 40 and girder 31 is suitably increasing also, and make the lateral area in V-type gap 90 be greater than heat radiator assembly 70 air outlet area 3/5 so that increased radiating efficiency.
In the time that rotary drilling rig is worked, the hot blast of discharging from the air outlet of heat radiator assembly 70 will be discharged rotary drilling rig by gap 90, thereby the hot blast of discharging is not easy to be subject to stopping of other equipment, can make within heat radiator assembly relatively easily remains on the temperature range of permission for a long time by the temperature of hydraulic oil.
In sum, the utility model is by being that heat radiator assembly reserves the passage that hot blast feeding is discharged when the layout, thereby heat radiator assembly can be dispelled the heat to rotary drilling rig more easily.Further, because heat radiator assembly can dispel the heat to rotary drilling rig better, therefore can reduce the requirement of the plant capacity of rotary drilling rig to heat radiator assembly, provide cost savings.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solutions of the utility model content, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
